DETAILED DESCRIPTION

[0028] The utility model is described below with specific examples, but is not limited to the utility model.

[0029] Example one

[0030] As Figures 1-6 shown, in this embodiment, a sliding block locking structure is provided, which comprises a clamping piece 1 assembled in the sliding block and a locking piece 4 assembled in the sliding rail.

[0031] The clamping piece 1 is fixedly installed in the sliding block by means of bolts and the like, and a gap is left between the clamping piece 1 and the sliding rail to avoid friction between the clamping piece 1 and the sliding rail when the sliding block moves. The clamping piece 1 is provided with a buffer surface 2, and the buffer surface 2 is internally embedded with a clamping groove 3.

[0032] The locking piece 4 comprises a wedge-shaped block 5, which can move vertically towards the inside of the sliding rail, and the wedge-shaped block 5 is provided with a clamping pin 6 on the wedge-shaped surface thereof.

[0033] The locking piece 4 is installed at the locking position of the sliding rail, and when the clamping piece 1 moves to the locking position, the buffer surface 2 contacts the wedge-shaped surface of the wedge-shaped block 5. When the buffer surface 2 contacts the wedge-shaped surface, the wedge-shaped surface will hinder the buffer cotton and the clamping piece 1, so as to slow down the clamping piece 1 in advance, improve the deceleration effect, make the sliding block more easily stationary, and push the wedge-shaped block 5 to move towards the inside of the sliding rail. When the clamping groove 3 moves to the inside of the clamping pin 6, the clamping pin 6 can lock the sliding block through the clamping piece 1. When the clamping pin 6 is clamped into the inside of the clamping groove 3, the clamping piece 1 can be fixed, so as to fix the clamping piece 1 and the sliding block on the sliding rail.

[0034] Example two

[0035] As Figures 1-6 shown, on the basis of example one, the structure of the locking piece 4 is provided in this embodiment, which is as follows:

[0036] The locking component 4 also includes a groove 7 and a vent pipe 8 formed inside the slide rail. The wedge block 5 is slidably installed inside the groove 7, and a sealing structure is provided between the wedge block 5 and the side wall of the groove 7. The groove 7 is connected to the vent pipe 8, which can inject gas into the groove 7. The gas can push the wedge block 5 to move outward from the slide rail. The vent pipe 8 is connected to an external air supply device. When it is necessary to unlock or reset the wedge block 5, gas is injected into the groove 7 through the vent pipe 8. Because of the sealing structure between the wedge block 5 and the side wall of the groove 7, the injected gas creates pressure in the groove 7, pushing the wedge block 5 to move outward from the slide rail, preparing for the next locking.

[0037] The wedge block 5 has a sliding hole 9 inside, and the locking pin 6 is slidably installed inside the sliding hole 9. The sliding hole 9 passes through the outside of the wedge block 5 and communicates with the sliding groove 7. The sliding hole 9 inside the wedge block 5 provides sliding space for the locking pin 6, and the sliding hole 9 is connected to the sliding groove 7. In this way, when the wedge block 5 moves or the air pressure in the sliding groove 7 changes, it may have a certain impact on the sliding of the locking pin 6 in the sliding hole 9, ensuring that the locking pin 6 can work normally.

[0038] The end of the locking pin 6 extends to the outside of the wedge block 5 and has a locking surface. When the slot 3 moves to the position of the locking pin 6, the locking surface can better cooperate with the slot 3, improve the stability of the locking, and ensure that the locking pin 6 can reliably lock into the slot 3 to lock the slider.

[0039] A sealing gasket is provided between the locking pin 6 and the side wall of the sliding hole 9. The locking pin 6 is slidably installed in the sliding hole 9 via a second elastic body. The sealing gasket between the locking pin 6 and the side wall of the sliding hole 9 can prevent gas leakage and ensure stable air pressure inside the sliding hole 9. The second elastic body enables the locking pin 6 to slide in the sliding hole 9, and when the locking pin 6 is engaged in the locking groove 3 or subjected to external force, the second elastic body can play a buffering and resetting role, ensuring the reliability of the locking pin 6.

[0040] When the wedge block 5 moves to the outermost part of the slide groove 7, the highest point of the buffer surface 2 is higher than the lowest point of the wedge surface on the wedge block 5. The friction between the wedge surface on the wedge block 5 and the buffer surface 2 is generated, thereby reducing the moving speed of the snap fastener 1.

[0041] Example 3

[0042] like Figures 1-6 As shown, based on Embodiment 1 and Embodiment 2, this embodiment provides a gas supply device, as detailed below:

[0043] The middle part of the ventilation pipe 8 is provided with a pipe 10, and the inside of the pipe 10 is slidably provided with two piston columns 11. The two piston columns 11 are connected with a first elastic body 12. When the front end of the ventilation pipe 8 is injected with gas, the gas enters the inside of the pipe 10 and pushes the piston columns 11 and the first elastic body 12 to move. Another piston column 11 moves towards the direction of the sliding groove 7, and the gas is injected into the sliding groove 7 to generate a pushing force on the wedge-shaped block 5.

[0044] The outer end of the ventilation pipe 8 extends to the outside of the sliding rail and communicates with an external gas supply tank to facilitate the supply of gas to the ventilation pipe 8. The external gas supply tank can provide stable gas pressure, and the gas is injected into the sliding groove 7 through the ventilation pipe 8 to control the movement of the wedge-shaped block 5, thereby achieving the unlocking and locking operations of the sliding block.

[0045] The material of the clamping piece 1 is rubber, which has certain elasticity and flexibility. When the buffer surface 2 contacts the wedge surface of the wedge-shaped block 5, the rubber material of the clamping piece 1 can better absorb the impact force and play a buffering role. At the same time, it can also increase the friction between the wedge surface and improve the deceleration effect. Moreover, the rubber material can provide certain elastic deformation when the clamping pin 6 is clamped into the clamping groove 3, so that the clamping is more compact.

[0046] The diameter of the pipe 10 is greater than that of the ventilation pipe 8. When the gas enters the pipe 10 from the ventilation pipe 8, the space of the pipe 10 becomes larger, and the gas pressure decreases relatively, so that the movement of the piston column 11 and the first elastic body 12 is more stable. At the same time, this structure design can play a certain buffering and pressure stabilizing role, which can ensure that the gas can stably push the piston column 11 to move towards the direction of the sliding groove 7, and provide a stable pushing force for the wedge-shaped block 5.

[0047] Working principle: The sliding block moves freely on the sliding rail, and the clamping piece 1 is fixed inside the sliding block and has a gap with the sliding rail to avoid generating additional friction force and hinder the normal movement of the sliding block.

[0048] When the sliding block moves to the locking position, the buffer surface 2 of the clamping piece 1 contacts the wedge surface of the wedge-shaped block 5. The wedge surface hinders the clamping piece 1 to slow down in advance, and pushes the wedge-shaped block 5 to move towards the inside of the sliding rail. As the sliding block continues to move, the clamping groove 3 on the clamping piece 1 moves to the corresponding position of the clamping pin 6, the clamping pin 6 is clamped into the clamping groove 3, and the sliding block is fixed on the sliding rail by fixing the clamping piece 1, thereby completing the locking.

[0049] The external gas supply device injects gas into the ventilation pipe 8, and the gas pushes the piston column 11 and the first elastic body 12 to move after entering the pipe 10, so that another piston column 11 injects the gas into the sliding groove 7. Due to the sealing structure of the wedge-shaped block 5 and the side wall of the sliding groove 7, the gas pressure in the sliding groove 7 pushes the wedge-shaped block 5 to move towards the outside of the sliding rail, so that the clamping pin 6 is separated from the clamping groove 3, thereby achieving the unlocking and preparing for the next locking.

[0050] Finally, it should be noted that the above examples are intended to illustrate and not limit the technical solutions of the present application. Although the present application has been described in detail with reference to the above examples, those skilled in the art should understand that the present application can still be modified or equivalently replaced without departing from the spirit and scope of the present application, and any modification or partial replacement thereof should be covered in the scope of the claims of the present application.
