Abstract
The utility model relates to a structure-improved cipher-code-changing piece of a puzzle lock, which comprises a piece body and a cipher-code-changing gear. A cam is arranged on the piece body. A cipher-code-changing block is arranged between the cam and the cipher-code-changing gear. The lower part of the cipher-code-changing block is provided with teeth. The upper part of the cipher-code-changing block is provided with a spring. The outline of the cam is contacted with the spring. The cipher-code-changing piece which is provided by the utility model uses the elasticity of the spring to make the cipher-code-changing block engaged with the cipher-code-changing gear, which ensures the performance stability of the cipher-code-changing piece and extends the service life of the cipher-code-changing piece.
Description
The utility model relates to the code converter chip of a kind of accessory of mechanical code lock, particularly coded lock.
Code converter chip is as the crucial accessory of mechanical code lock, and the height of its quality will directly have influence on the security performance and the application life of coded lock.More advanced code converter chip is that the heart is provided with a change sign indicating number gear therein at present, utilizes change sign indicating number gear that code converter chip is located.But such code converter chip all is to rely on the change code-bar between code converter chip lamellar body and the change sign indicating number gear that change sign indicating number gear and lamellar body are connected, and this will have better elastic by the changes persuing code-bar.Yet along with the growth of coded lock service time with become increasing of sign indicating number number of times, the elasticity that becomes code-bar can descend gradually, causes the degradation of code converter chip, occurs slippage phenomenon easily.
The purpose of this utility model is to overcome the problems referred to above, and a kind of structure improved coded lock code converter chip is provided, and it utilizes the elasticity of spring, effectively guarantees the code converter chip stable performance, long service life.
The purpose of this utility model realizes by following technical proposal: this structure improved coded lock code converter chip comprises lamellar body and becomes the sign indicating number gear, lamellar body is provided with cam, cam is axially fixed on the lamellar body by location-plate, be provided with the change code block between cam and the change sign indicating number gear, become the code block bottom and be provided with teeth, become code block and can be meshed with becoming the sign indicating number gear by these teeth, the top that becomes code block is provided with spring, and the profile of cam contacts with spring.This code converter chip is to utilize cam to push down the change code block, make to become code block and become the sign indicating number gears engaged, thereby realization becomes the sign indicating number gear and lamellar body is fixed together.When needs become sign indicating number, as long as rotating cam makes the change code block loosening, then with regard to change sign indicating number gear free to rotate.
Compare with existing code converter chip, the utility model utilizes the elasticity of spring to make the change code block and become the sign indicating number gears engaged, so can guarantee code converter chip stable performance, long service life owing between cam and change code block spring is set.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, lamellar body; 2, become code block; 2a, teeth; 3, become the sign indicating number gear; 4, open slot; 5, cam; 5a, square hole; 6, location-plate; 7, spring; 8, back-moving spring.
As shown in the figure, the code converter chip of this coded lock comprises lamellar body (1) and becomes sign indicating number gear (3).The turning cylinder of coded lock passes and becomes sign indicating number gear (3).Open slot (4) is arranged on the excircle of lamellar body (1).Cam (5) is arranged on the lamellar body (1), and cam (5) is axially fixed on the lamellar body (1) by location-plate (6).Becoming code block (2) is stuck between cam (5) and the change sign indicating number gear (3).Becoming code block (2) is meshed with a change sign indicating number gear (3) by teeth (2a).Become between code block (2) and the cam (5) and be provided with spring (7).In addition, also be provided with back-moving spring (8) between change code block (2) and the lamellar body (1).Two back-moving springs (8) are set in the present embodiment.The center of cam (5) is a square hole (5a).When becoming code operations, pass square hole (5a), cam (5) is rotated by becoming the sign indicating number bar.This code converter chip utilizes cam (5) to push down change code block (2) and change code block (2) is meshed with a change sign indicating number gear (3) through spring (7).After rotating cam (5) made change code block (2) loosening, becoming code block (2) will separate with a change sign indicating number gear (3) under the effect of back-moving spring (8), and energy freely rotate thereby assurance becomes a sign indicating number gear (3).
Claims (2)
1, a kind of structure improved coded lock code converter chip, comprise lamellar body (1) and become sign indicating number gear (3), lamellar body (1) is provided with cam (5), cam (5) is axially fixed on the lamellar body (1) by location-plate (6), it is characterized in that described cam (5) and become to be provided with between the sign indicating number gear (3) becoming code block (2), become code block (2) bottom and be provided with teeth (2a), becoming code block (2) can be meshed with a change sign indicating number gear (3) by these teeth (2a), the top that becomes code block (2) is provided with spring (7), and the profile of cam (5) contacts with spring (7).
2, coded lock code converter chip according to claim 1 is characterized in that also being provided with back-moving spring (8) between described change code block (2) and the lamellar body (1).
