The utility model further discloses a supporting door lock for the insurance door lock mechanism. The insurance door lock mechanism assists in solving a problem that a track door lock with a traditional linear lock core key can not be used because of an insufficient torque, and the insurance door lock mechanism has advantages of reliable operation, simple structure, strong practicability, accurate motion of the hinged door lock tongue mechanism and high transmission efficiency.
Description
Technical field
The utility model relates to a kind of lockset, specifically, is a kind of insurance lock mechanism of hinge door lock and supporting hinge door lock thereof.
Background technology
In the rail vehicle manufacturing, select the car door of hinged door usually for use as driver's cabin; The used key form of the insurance lock mechanism that on hinged door, is provided with mainly is cubic key or triangle key; This key form is simple, and the strength reliability of key own is high, uses also relatively extensively; But this type Key structure is simple, is easy to copied, and therefore uses in public to exist great potential safety hazard.Now people's tending to more uses a traditional letter lock core key to be used for substituting cubic key or triangular key; But the moment of torsion of a common letter lock core key is less relatively; And the maximum transmission output torque to lock requires than higher on rail vehicle; Regular meeting key occurs and twists off the incident in lockhole in actual use, brings inconvenience for daily use.
Summary of the invention
Goal of the invention: the purpose of the utility model is to provide a kind of brand-new door lock mechanism to solve the problem of using a traditional letter lock core key moment of torsion not enough, the utility model discloses supporting with it door lock simultaneously.
Technical scheme: the utility model adopts following technological means to realize:
A kind of insurance lock mechanism of hinge door lock; Described insurance lock mechanism comprises that described lock core is a letter lock core; Lock core is connected through bearing pin with lock core gear; Lock core gear and transition gear are in transmission connection, and transition gear is arranged on the gear shaft and the rack-and-pinion that is connected with the insurance dead bolt is set on gear shaft, and the gear ratio of described transition gear and lock core gear is 1:4.
[
0005] described insurance lock mechanism also comprises little handle, said handle and the coaxial setting of gear shaft are provided with the little spring that resets between insurance dead bolt and lock body.
A kind of hinge door lock comprises above-mentioned insurance lock mechanism and spring bolt mechanism, and described spring bolt mechanism is a cam mechanism.
Described cam mechanism comprises handle, cam, dead bolt, reseting pressuring spring and support set; Described handle is connected with cam is coaxial; Cam connects the tail end of dead bolt, between dead bolt and support set, reseting pressuring spring is set, and on gear shaft, also is provided with the cam stop piece that limits angular displacement of the cam.
Beneficial effect: the utility model has solved letter lock core key moment of torsion deficiency in the track door lock at one stroke, the problem that can't use, and it is reliable, and is simple and practical, and the motion of hinged door spring bolt mechanism is accurate, and transmission efficiency is high.

The specific embodiment
Below in conjunction with Figure of description the utility model is further detailed:
The utility model relates to a kind of insurance lock mechanism of hinge door lock; It comprises lock core 11, lock core gear 10, transition gear 7, gear shaft 8 and insurance dead bolt 9; Lock core 11 is the yi word pattern lock core; It connects lock core gear 10, and lock core gear 10 connects transition gear 7 through gear drive, and transition gear 7 is arranged on the gear shaft 8 and the rack-and-pinion that is connected with insurance dead bolt 9 is set on gear shaft 8.When key inserts in the lock core 11 and begins to rotate; Connect the also rotation thereupon of lock core gear 10 of lock core 11, then drive transition gear 7 rotations, the rotation of transition gear 7 has driven the rotation of gear shaft 8; The rotation of gear shaft 8 has caused rack-and-pinion laterally to move; Rack-and-pinion is connected on the insurance dead bolt 9, therefore insures dead bolt 9 and laterally moves thereupon, accomplishes the on-off action of safety lock.Because the gear ratio between lock core gear 10 and the transition gear 7 differs greatly, and specifically, is 1:4; Be that lock core gear rotates 360 °, transition gear 7 rotates 90 °, so transition gear 7 is when rotating along with lock core gear 10; The corresponding amplification of its moment of torsion so, produces the strength that same moment of torsion then need spend and reduces; Even if therefore use yi word pattern lock core key also can produce enough moments of torsion, thereby satisfied the switching requirement of track train door.Said insurance lock mechanism also comprises wisp hand 6, the little spring 12 that resets, and wisp hand 6 and gear shaft 8 connect as one through pin, and an end of the little spring that resets articulates insurance dead bolt 9, and the other end is fixed on the lock body.Wisp hand 6 is used at door inner control insurance dead bolt 9, and the little spring 12 that resets is used to insurance dead bolt 9 moment of torsion of the maintenance under the vibration environment is provided.
The utility model discloses the hinge door lock that a kind of and said insurance lock mechanism matches simultaneously, and it comprises handle 1, cam 2, dead bolt 3, reseting pressuring spring 4 and support set 5, described handle 1 and 2 coaxial connections of cam; Cam 2 connects the tail end of dead bolt 3, reseting pressuring spring 4 is set, between dead bolt and support set when swing handle 1; Drive cam 2 rotates thereupon; The rotation of cam 2 has driven dead bolt 3 and has laterally moved completion withdrawal action, and the withdrawal of dead bolt also makes reseting pressuring spring 4 produce deformation, after unclamping handle 1; Reseting pressuring spring 4 restores to the original state, and dead bolt 3 is resetted.In the utility model, on gear shaft 8, also be provided with the cam stop piece 13 of restriction cam 2 rotational angles, when safety lock is locked; Cam stop piece 13 also turns on the position with cam 2 formation dead points simultaneously; Cam 2 can't be rotated, cause the locked of handle 1, realize insurance function.
