Abstract
The utility model discloses a sheet type spring for a dialing mechanism of a mechanical coded lock. The sheet type spring is characterized in that the sheet type spring is arranged below the tail part of the dialing sheet of the mechanical coded clock, wherein the dialing sheet is used for dialing a code, the sheet type spring is in a U-shaped structure which is formed by punching and bending a spring plate and consists of an upper sheet, a lower sheet and a transition circular arc, and the end part of the lower sheet of the sheet type spring is provided with wing plates which face outwards and are vertical to the lower sheet. The sheet type spring can bear the long-term high-frequency working state so as to enable the action of the dialing sheet to be reliable and has overlong service life.
Description
Technical field
The utility model relates to the dial-up mechanism of mechanical code lock, specifically is meant the chip type spring in a kind of dial-up mechanism of stirring combination disk.
Background technology
Mechanical code lock is applied to safety cabinet, file cabinet, security door, silver vault door widely now, even has been applied in the family.Its basic functional principle is mostly consistent, at outer side of door the dial of being with scale is set, and the dial of high-grade rotating disc type mechanical code lock is simultaneously also as unlocking handle; It is marked with the scale of band numeral, also claims to unblank handwheel, is furnished with some notched disks on the inboard mandrel that is provided with of door; The main shaft of dial stretches into an inboard and is fixedly connected with mandrel, the outer dial of rotary door then, and the main shaft of dial drives disk and rotates in order; All aim at the pin plate of unblanking of bolt-operating mechanism when the breach of some disks; The pin plate of unblanking moves down the entering breach, has then removed the restriction of splitting bolt mechanism, and bolt-operating mechanism is taken advantage of a situation bolt is opened.
Chinese patent 02135963.6 has been introduced a kind of mechanical thumbwheel puzzle lock, comprises multi-disc ring-type combination disk, chassis, lock bolt, bolt-operating mechanism, detent mechanism, shell and dial, also comprises dial-up mechanism, resetting-mechanism and spy ink recorder structure.Dial-up mechanism comprises structural frame, dial-up piece, control device.Control device includes sleeve, ratchet, control panel.Structural frame is a cylindrical shape; Structural frame is fixedly connected with the main shaft of outside unlocking handle through connecting axle; On the cylinder of structural frame, have the groove of placing the dial-up piece, the dial-up piece is a sheet, is contained in the groove of structural frame; Be provided with spring in the structural frame groove of dial-up piece tail end, the cephalic par of dial-up piece can pop up under the effect of spring.Sleeve can be enclosed within outside the structural frame cylinder with relatively rotating; Sleeve surface along the circumferential direction has slotted eye; This slotted eye can supply dial-up build end to come in and go out, and under the effect of spring, the cephalic par of dial-up piece can pop up slotted eye; Under the compressing of sleeve, the cephalic par of dial-up piece can also be withdrawn in the groove.On the end face of sleeve near control panel one side, be provided with ratchet, be provided with ratchet in the position of relative ratchet, the outer rim of control panel is a cam-like, and the cam at the edge of the controlled dish of ratchet is controlled and matched with ratchet.Under the effect of outdoors unlocking handle; Structural frame and sleeve relatively rotate or are static; The cam control of the controlled plate edge of ratchet cooperates with ratchet, and control dial-up piece ejects the groove from sleeve under spring action in order, and the dial-up piece of ejection cooperates with the combination disk of the ring-type that is positioned at its outer rim; The breach of some combination disk is all aimed at the pin plate of unblanking of bolt-operating mechanism, can operate bolt-operating mechanism and open the door.
Wherein, spring is as one of between the critical component in the dial-up mechanism, and the application life of the spring that multi-form or different processing technologys are made is different, and the functional reliability of lock core dial-up mechanism is had fundamental influence.Spirality compression spring is not suitable for miniaturization lock core dial-up mechanism and uses, though adopt torsion spring can realize the upspringing function of dial-up piece, limited owing to the in-house space of lock core dial-up, it is very little that torsion spring can only be done, and fatigue break takes place easily.In case the spring fatigue phenomenon that fractures occurring is exactly major accident.
The utility model content
The utility model technical issues that need to address provide a kind of chip type spring that mechanical cipher is locked dial-up mechanism that is used for that can bear long-time high-frequency operation state.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
The chip type spring that is used for mechanical code lock dial-up mechanism; Below the afterbody of the dial-up sheet of stirring password of mechanical code lock, be provided with chip type spring; Said chip type spring by the latch plate bending ram form by last slice, the following U type structure formed of sheet and transition arc, the end of sheet is provided with outside and the vertical wing plate of following sheet under the chip type spring.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
The chip type spring of the utility model design can bear long-time high-frequency operation state, makes the reliable in action of dial-up sheet; Application life with overlength; Be not common torsion spring intensity can reach, the wing plate that following of chip type spring head is provided with has effectively been located chip type spring; Restriction chip spring shaft to move radially, make coded lock work more safe and reliable.
