Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, a fixing structure of a safety lock for an electric operating mechanism is arranged on a base 1 of the electric operating mechanism, and comprises a lock case 2 fixed on the base 1, a lock cylinder 3 arranged inside the lock case 2, and a rotating member 4 fixed on the lock cylinder 3, wherein the lock cylinder 3 drives the rotating member 4 to rotate, a fixing hole 41 is arranged at the axis of the rotating member 4, a threaded hole 31 is arranged at the bottom of the lock cylinder 3, a fixing screw 5 is inserted into the fixing hole 41, the fixing screw 5 is matched with the threaded hole 31, an anti-rotating assembly is arranged between the lock cylinder 3 and the rotating member 4, an anti-lost member for preventing the lock cylinder 3 and the rotating member 4 from being mistakenly matched is arranged on the anti-rotating assembly, the anti-rotating assembly is adopted to ensure the normal work of the rotating member 4 even if the fixing screw 5 is loosened, and the installation position of the rotating member 4 is fixed, fool-proof piece can prevent the position installation mistake of rotating member 4, improves the installation effectiveness.

The anti-rotation component can be in various forms, for example, a pin is matched with a pin hole, and the anti-rotation component is realized by matching a groove 42 with a projection 32 in the scheme, as shown in fig. 3 and 5, the anti-rotation component comprises a groove 42 arranged on the rotating part 4 and a projection 32 arranged on the lock cylinder 3, the groove 42 and the projection 32 are both in a polygonal structure, the groove 42 can also be arranged on the lock cylinder 3, the opposite projection 32 is arranged on the rotating part 4, the projection 32 is inserted into the groove 42 and is matched with the groove, and the lock cylinder 3 drives the projection 32 or the groove 42 to rotate, so that the corresponding groove 42 or the projection 32 is driven to rotate, and the rotating part 4 is operated to rotate; because the groove 42 and the protrusion 32 are matched with each other to a certain depth, if the fixing screw 5 is loosened, the protrusion 32 cannot be separated from the groove 42, so that the operation of the rotating member 4 can be continuously ensured; in the scheme, the polygonal structure adopts a regular quadrangle, and in the installation process, the polygonal structure is in various shapes, not only is a regular polygon, but also can be in other special-shaped structures, and the polygonal structure is used for driving the rotating member 4 to rotate.

The purpose of the fool-proof piece is to ensure that the lock core 3 and the rotating piece 4 are correctly installed, when the two are incorrectly inserted, the fool-proof piece is not matched, the fool-proof piece can also have various structural forms, and the fool-proof piece is realized by manufacturing irregular shapes on a polygonal structure, in the scheme, the fool-proof piece is a chamfer 33 arranged on one corner of the polygonal structure, for a regular quadrangle, the chamfer 33 is arranged on one corner of the regular quadrangle, so that the regular quadrangle is formed into an asymmetrical pentagon, and the protrusion 32 and the groove 42 are both pentagons which are matched with each; in other technical schemes, 2-3 feet can be set as the chamfers 33, and the functions can be realized.

The existing safety lock of the electric operating mechanism is fixed only by the fixing screw 5, so that the rotating force is relatively light when the safety lock rotates, and meanwhile, the safety lock is not easy to position after rotating in place, so that the rotating part 4 is easy to rotate, and safety accidents are caused.

The damping part 6 in the scheme adopts a wave washer, the wave surface of the wave washer is contacted with the rotary part 4, the wave washer has certain elasticity, and the damping effect is realized by the resistance generated by the elasticity of the wave washer to the rotation of the rotary part 4; furthermore, the highest position of the wave-shaped surface of the wave-shaped washer is abutted against the base 1, and the lowest position of the wave-shaped surface is abutted against the rotary member 4.

Simultaneously convenient quick installation and lock shell 2 can not rotate base 1 on set up a location breach lock shell 2 on set up a location arch 22, location arch 22 insert in the location breach, location arch 22 and the cooperation realization of location breach fix a position fast and the installation.

Further, for convenience, fixing can be completed by using one fixing screw 5, as shown in fig. 3 and 4, a first step 21 is arranged in the lock case 2, a second step 34 is arranged on the lock cylinder 3, the first step 21 is matched with the second step 34, the lock cylinder 3 is tightened by the fixing screw 5 so that the second step 34 is matched with the first step 21, and the lock case 2 is fixed on the base 1.

In conclusion, the rapid installation is realized by matching the protrusion 32 and the groove 42 of the anti-rotation component, the fixing screw 5 can work normally even if loosened, and meanwhile, the error matching of the protrusion 32 and the groove 42 is prevented by the foolproof piece, so that the quick and accurate matching can be realized; damping part 6 adopts wave washer, increases the resistance to revolving part 4 through wave washer's elasticity, and the resistance can not be too big, has certain resistance in rotatory, feels better, conveniently fixes a position its revolving part 4 simultaneously, guarantees that it can not oneself rotate, prevents to revolve round, improves the security performance.
