The utility model discloses an embodiment relates to a track optional position locking mechanism, as shown in fig. 1-4, including track slider lock 1, track slider lock 1 on seted up socket 2, the inner wall department symmetry of this socket 2 both sides is provided with two locking device, locking device include binding clip 4, oblique ejector pad 9 and piston head 13, track slider lock 1 inside both sides that are located socket 2 respectively be equipped with a vertical piston chamber 8 of arranging, all install a piston head 13 in every piston chamber 8, 13 one end of piston head be connected with oblique ejector pad 9, track slider lock 1 in be located oblique ejector pad 9 one side and install lateral sliding's binding clip 4, this binding clip 4 one end runs through 2 inner walls of socket and the cover has elastic sealing element 14, oblique ejector pad 9 one end install reset spring 11.

The socket 2 is in a U-shaped opening shape.

And the outer side of the track sliding block lock 1 is provided with an air inlet 6 and an air outlet 7 which are communicated with a piston cavity 8.

The upper end of the piston cavity 8 penetrates through the upper end face of the track slider lock 1, an opening in the upper end of the piston cavity 8 is sealed through the piston cover 3, and the piston cover 3 is detachable through the screw, so that the condition of each part in the piston cavity 8 can be conveniently checked.

An inner cavity 15 communicated with the piston cavity 8 is formed in the track slider lock 1, the lower end of the piston cavity is located in the inner cavity 15, a guide seat 10 is installed in the inner cavity 15, a return spring 11 is installed between the lower end of the guide seat 10 and the bottom of the inner cavity 15, the guide seat 10 is sleeved on an inclined push block 9, two bearing needle rollers 12 are installed on two sides of the inclined push block 9 in the guide seat 10 respectively, and one bearing needle roller 12 is located between the inclined surface of the inclined push block 9 and the tong head 4.

One side of the inner cavity 15 penetrates through the outer side of the track slider lock 1, an opening in one side of the inner cavity 15 is sealed through the side sealing cover 5, the side sealing cover 5 is detachable through screws, and therefore the condition of each component in the inner cavity 15 can be conveniently checked.

The binding clip 4 include axially connected big cylinder 16 and little cylinder 17, big cylinder 16 one end around little cylinder 17 arranged round annular inner groovy 18, elastic sealing element 14 install in annular inner groovy 18, little cylinder 17 one end run through the inside wall of socket 2, the perforation that runs through the inside wall of socket 2 can only supply little cylinder 17 to pass, big cylinder 16 can't pass the perforation. The elastic sealing element 14 is an elastic sealing ring, which not only functions to seal the inner cavity 15, but also helps the bit 4 to reset.

The locking principle is as follows: the guide rail sliding block lock 1 is sleeved on a proper track through the sleeve joint 2, when the air inlet 6 is filled with air, the piston head 13 drives the inclined push block 9 to move downwards together, the inclined surface of the inclined push block 9 pushes the bearing needle roller 12 to move outwards, the tong heads 4 move outwards, and the two tong heads 4 move outwards simultaneously to lock the track; when the piston head 13 moves downwards and contacts with the guide seat 10, the guide seat 10 is pushed to move downwards, and meanwhile, the bearing roller 12 also moves downwards, so that the bearing roller 12 is adjusted to reach the central position of the tong head 4, the force on the tong head 4 is more balanced, and the track is better locked.

Locking at any position: an external force driving device is installed on the guide rail sliding block lock, and under the action of the driving device, the guide rail sliding block lock 1 can slide on the rail at will and is matched with air inlet locking to realize the locking function at any position.

The principle of relaxation is as follows: when the air inlet 6 admits air, a part of the return spring 11 pushes the inclined push block 9 to move upwards, and a part of the return spring 11 pushes the guide seat 10 to move upwards, so that the bearing needle roller 12 is loosened, the bearing needle roller 12 simultaneously loosens the tong head 4, and the elastic sealing element 14 has resilience and can push the tong head 4 to loosen the rail, so that the rail is loosened.
