[0026] Working principle description:

[0027] The basic function of this equipment is the same as that of the utility model patent named "Intermediate Frame Connection Structure of a Mining Transfer Machine" (application number 201822169086.7). The connection structure body is matched and installed by a first-level connection female part and a first-level connection male part 1. When the first-level connection female part and the first-level connection male part 1 need to be matched and installed, first press the upper button 6 and the lower button 10. This operation can be performed with one hand. The upper button 6 compresses the first spring 4 to drive the upper linkage block 7 to move. The movement of the upper linkage block 7 drives the upper limit rod 9 to retract into the installation slot 2. During this process, the upper pressure block 8 compresses the third spring 14, and the lower button 10 compresses the second spring 5 to drive the lower linkage The block 11 moves, and the lower linkage block 11 moves to drive the lower limit rod 13 to retract into the installation groove 2. During this process, the lower pressing block 12 compresses the fourth spring 16, and then matches the primary connection female component and the primary connection male component 1; when the primary connection female component and the primary connection male component 1 are matched, release the upper button 6 and the lower button 10, and the upper button 6 rebounds under the action of the first spring 4, and the upper limit rod 9 rebounds into the primary connection female component under the action of the third spring 14 and the fourth spring 16 to be fixed. Similarly, the lower button 10 rebounds under the action of the second spring 5, and the lower limit rod 13 rebounds into the primary connection female component under the action of the third spring 14 and the fourth spring 16 to be fixed.

[0028] Preferably, a rubber pad is installed in the mounting groove 2. Such a structural design reduces friction damage to the mounting groove 2 and prolongs the service life of the equipment.

[0029] Preferably, a rubber cushion is installed on the support block 3. Such a structural design reduces the friction damage to the support block 3 and prolongs the service life of the equipment.

[0030] Preferably, the upper button 6 and the lower button 10 are provided with anti-slip grooves. Such a structural design makes the upper button 6 and the lower button 10 more convenient to operate.

[0031] Preferably, the lower pressing block 12 and the upper pressing block 8 are provided with a rubber cushion layer. Such a structural design reduces the friction damage suffered by the lower pressing block 12 and the upper pressing block 8, thereby extending the service life of the equipment.

[0032] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
