Patent name: production method of password door lock
Technical field:
The invention relates to a password type door lock, in particular to a password type door lock which is arranged on the door panel, and has the function of finding the original unlocking number and resetting the new unlocking number, and can temporarily release the locking function after the door panel is opened.
Background technology:
Password lock is a kind of common simple lock. The user can change the state of the lock center to unlock or lock by turning each word wheel on the password lock, so as to omit the necessity of the user carrying the key and increase the convenience of use. Therefore, when the password lock is applied to the door panel, it can be adjusted to the unlocked or locked state to control the rotation of the handle that can drive the latch. When the password lock is unlocked, the handle can drive the latch to open the door panel. When the password lock is locked, the handle will be locked so that it can not drive the latch and the door panel will be in a closed state. However, the memory of ordinary people is limited, or it is easy to forget the unlocking number in a hurry. When the password lock of the forgotten unlocking number cannot be opened, the only way to release the locking state is to destroy the password lock and the door panel. Therefore, for most users, the existing technology of the password lock does have its inconvenience in use; moreover, when adjusting After the whole password is locked to the unlocking state and the door panel is opened, the user should dial the disordered character wheel first, and then enter the other side of the door panel, so as to prevent the intentional person from peeping and recording the unlocking number of the password lock; however, once the disordered character wheel is dialed, the password lock will show the locking state and the position of the locking handle, so that the door panel will show the closed state again, so it is necessary to repeatedly enter and exit the door panel The users of the entrance and exit of the door panel also have their own inconveniences. As mentioned above, the cryptographic door lock of the prior art really needs further improvement.
summary of the invention
In view of the disadvantages of the prior art, the invention designs a password type door lock, hoping to provide a password type door lock which can find the original unlocking number, reset the new unlocking number, and temporarily release the locking function after the door panel is opened. In order to achieve the purpose of the invention, the technical scheme of the invention is to make a cipher type door lock include a middle empty shell body, which is provided with a support frame; a handle group, which is penetrated on the shell; a number lock group, which is arranged in the shell body, the number lock group includes a lock bolt, a plurality of sleeves and a plurality of word wheels, the lock bolt is connected with the handle group, which has a base, the The top surface of the base is axially protruded and formed with a main rod body. The main rod body is spaced and surrounded by a plurality of alignment parts. Each alignment part is formed with a plurality of positioning bumps along the axial spacing of the main rod body. A through groove is formed between two adjacent positioning bumps, and the through grooves of each alignment part are respectively connected. The sleeve is sequentially sleeved on the main rod body of the lock bolt, and each sleeve is formed with a plurality of alignment parts The alignment convex block and a number finding hole are formed around the inner wall surface of the sleeve near the bottom end, and protrude between one through groove of the main rod body. Each alignment convex block can be corresponding to the positioning convex block between two specific adjacent alignment parts of the lock bolt. The number finding hole is penetrated and formed on the sleeve, and the gear wheel is respectively set on each sleeve A number finding group is arranged in the shell and on the side of the number lock group. The number lock group includes a pushing piece, a plurality of alignment pins and a key lock center. The pushing piece is arranged on the side of the bearing frame of the shell, on which a plurality of pushing convex parts and a transverse groove are formed. The pushing convex parts are spaced on the side of the corresponding bearing frame of the pushing piece, and the transverse groove runs through the pushing piece horizontally The alignment pin is movably and horizontally penetrated into the support frame, one end of each alignment pin is against the outer wall surface of the corresponding sleeve, the other end of the alignment pin is against a corresponding pushing convex part of the pushing member, a second elastic part is arranged between each alignment pin and the inner wall surface of the support frame, the second elastic part pushes the alignment pin against the pushing member, and the key lock Center It is arranged on the support frame and protrudes outside the shell. The inner end of the support frame protrudes a driving rod at the eccentric position, and the driving rod passes through the transverse groove of the pushing member. In the number lock group, the sleeve can be formed with a convex ring and at least a pair of number bumps, the convex ring protrudes radially and surrounds the outer wall surface of the sleeve near the bottom end, the pair of number bumps are formed on the outer wall surface of the sleeve near the bottom end, the inner wall surface of each wheel is spaced around the sleeve to form a plurality of pair of number bumps, and the pair of number bumps of the sleeve are correspondingly buckled on the wheel The number lock group may include a first elastic member and a press button, the first elastic member is sleeved on the main rod body of the lock bolt, and is butted between the base of the lock bolt and the sleeve, the press button is penetrated on the shell, and butted on the sleeve at the top of the main rod body close to the lock bolt. The side of the base of the lock bolt of the above-mentioned number lock group can be formed with a set of joint parts, which are internally formed with a holding groove; the number lock group can contain a certain position block, the positioning block is arranged in the holding groove of the lock bolt group joint part, the bottom end of the number lock group can be formed with a clamp part, the clamp part is connected with the handle group; the password lock can include an unlocking group, the unlocking group is penetrated in the shell The rear side of the body comprises an adjusting rod, a driving rod and a driving rod, the adjusting rod penetrates the fitting part of the lock bolt and protrudes to the fixed part
