The invention aims to provide a mechanical locking device with an electric limit function, and solves the problem that the conventional pure mechanical locking device is easy to operate by mistake. The device is simple, reliable, simple, convenient and feasible, and can be subjected to modularized integrated design.

The technical scheme who realizes above-mentioned purpose and take, including fitting pin and locking seat, fitting pin one end is equipped with the handle, and the handle passes through the stop pin to be fixed on the fitting pin, and fitting pin middle part symmetric position is equipped with two backing pins, and the fitting pin other end is equipped with the spring, be equipped with shallow spout, dark spout and micro-gap switch installation face in the locking seat, micro-gap switch passes through hexagon socket head cap screw A to be fixed on the locking seat, and the locking seat is equipped with the dust cover outward, and the dust cover passes through countersunk screw to be fixed on the locking seat, and the locking seat passes through hexagon socket head cap screw.

Compared with the prior art, the invention has the following advantages.

1. The invention solves the technical problem that the existing mechanical locking mode is easy to operate by mistake, and has the characteristics of simple and reliable structure, integration and modular design;

2. on one hand, the mechanical limit is realized through the locking pin, and on the other hand, the feedback signals of locking and unlocking are given through the micro switch to play a role in electric limit, so that the reliability of locking and unlocking is high.

Drawings

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

FIG. 1 is a cross-sectional structural view of the present invention;

FIG. 2 is a schematic of the three-dimensional structure of the present invention;

FIG. 3 is a schematic three-dimensional structure of the locking socket of the present invention;

shown in the figure: 1. the novel anti-theft lock comprises a handle, a stop pin 2, a locking pin 3, a stop pin 4, a dust cover 5, a microswitch 6, a hexagon socket head cap screw A7, a locking seat 8, a rubber gasket 9, a spring 10, a countersunk head screw 11, a hexagon socket head cap screw B12, a shallow sliding groove 13, a deep sliding groove 14 and a microswitch mounting surface 15.

Detailed Description

This device includes fitting pin 3 and locking seat 8, 3 one ends of fitting pin are equipped with handle 1, and handle 1 passes through stop pin 2 to be fixed on fitting

3, and 3 middle part symmetric positions of fitting pin are equipped with two backing pins 4, and the 3 other ends of fitting pin are equipped with spring 10, be equipped with shallow spout 13, dark spout 14 and micro-gap switch installation face 15 in the locking seat 8, micro-gap switch 6 passes through hexagon socket head cap screw A7 to be fixed on locking seat 8, and locking seat 8 is equipped with dust cover 5 outward, and dust cover 5 passes through countersunk screw 11 to be fixed on locking seat 8, and locking seat 8 passes through hexagon socket head cap screw B12 to be fixed on rubber gasket 9.

The shallow sliding groove 13 and the deep sliding groove 14 are respectively provided with two grooves, the shallow sliding groove 13 and the deep sliding groove 14 are vertically arranged on the locking seat 8, and the stop pin 4 is switched by the handle 1 to slide in the shallow sliding groove 13 and the deep sliding groove 14, so that the locking pin 3 is unlocked and locked.

Example (b):

the utility model provides a spacing mechanical locking device of electrified, as shown in figure 1, including fitting pin 3 and locking seat 8, 3 one ends of fitting pin are equipped with handle 1, and handle 1 passes through stop pin 2 to be fixed on fitting

In the invention, the handle 1 is rotated to enable the stop pin 4 to align with the deep sliding groove 14 on the locking seat 8, under the action of the elastic force of the spring 10, the stop pin 4 slides along the deep sliding groove 14, the locking pin 3 extends out, and the stop pin 4 triggers the micro switch 6 to give out an electric signal, so that mechanical locking and electric limiting are realized; when the handle 1 is pulled, the stop pin 4 slides upwards along the deep sliding groove 14, the micro switch 6 is triggered again, a closing signal is given, after the stop pin 4 slides to the tail end, the handle 1 is rotated by 90 degrees, so that the stop pin 4 is aligned with the shallow sliding groove 13, the handle 1 is released, and under the elastic force action of the spring 10, the stop pin 4 slides into the shallow sliding groove 13 and is clamped therein, so that unlocking is realized; the locking force is increased through the spring 10, so that locking and unlocking looseness under the environments of vibration and the like are avoided; the stop pin 4 triggers the microswitch 6 to give an opening and closing electric signal, so that the purpose of electric limiting is realized, and equipment damage caused by misoperation is avoided.

The device has simple and reliable structure, integrated and modularized design, can be applied to the limit of equipment, and plays the dual limit role of mechanical limit and electrical limit, so the locking and unlocking reliability of the device is high.
