2. Secondly, the staff can be fast with the dead lever spiro union in the threaded hole when taking place danger for the push pedal promotes the telescopic link and can provide the helping hand, makes to have safe distance between two mine cars, places the staff and is extrudeed the cell-phone, has improved the device's factor of safety.

Drawings

FIG. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a structural diagram of the connection between the telescopic rod and the protective casing;

figure 3 is a side view of the protective housing of the present invention.

In the drawings, the corresponding relationship between the component names and the reference numbers is as follows: the protection device comprises a protection shell 1, an expansion link 2, a bump 21, a clamping groove 22, a damping spring 3, a clamp 4, a reset button 5, a contact 6, a stress arm 7, a fixed rod 8, a reset spring 9, a push plate 10 and a threaded hole 11.

Detailed Description

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example (b):

as shown in fig. 1-3;

the embodiment provides a coal mine car coupling mechanism, includes: protecting sheathing 1, telescopic link 2, damping spring 3, anchor clamps 4, reset button 5 and reset spring 9, protecting sheathing 1's both sides fixedly connected with damping spring 3, damping spring 3's other end fixedly connected with anchor clamps 4, damping spring 3's inside is equipped with telescopic link 2, telescopic link 2's inside is provided with push pedal 10, push pedal 10's top is provided with lug 21, lug 21's top is equipped with draw-in groove 22, push pedal 10's bottom fixedly connected with receives the arm of force 7, the other end that receives arm 7 is equipped with contact 6, protecting sheathing 1's inside is provided with screw hole 11, the inside dead lever 8 that is provided with of screw hole 11, the one end fixedly connected with reset button 5 of screw hole 11 is kept away from to dead lever 8, the surface.

Wherein, dead lever 8 and contact 6 are 180 horizontal installation, help the accurate transmission of thrust, improve the protection to the hand.

Wherein, the contact 6 is a rubber hemisphere to enhance the friction force of the contact surface.

Wherein, anchor clamps 4 are the arc form, and inside is equipped with the antiskid rubber arch and is favorable to consolidating the connection between the mine car, avoids appearing the phenomenon of taking off the car.
