DETAILED DESCRIPTION

[0023] The utility model is further described below in combination with the drawings.

[0024] The directions involved in the specification are all in the direction of the quick clamping device of the inflation bottle when it is working normally, and are not limited to the directions when it is stored and transported, and only represent relative positional relationships, not absolute positional relationships.

[0025] Example one:

[0026] As Figure 1 shown, a quick clamping device of an inflation bottle, comprising a connecting shaft 3 fixed at one end on a main shaft and connected at the other end to a pull rod 2 of the inflation bottle 1. The connecting shaft 3 is provided at the end connected to the main shaft with a mounting flange 31, facilitating the mounting and dismounting of the entire clamping device.

[0027] As Figure 2 and Figure 3 shown, the connecting shaft 3 is designed as a hollow shaft, which can communicate with the inside of the main shaft, facilitating the mounting of the inflation device. The pull rod 2 is inserted into the shaft hole of the hollow shaft. In order to realize the relative position fixing and quick clamping function of the pull rod 2 and the connecting shaft 3, the outer peripheral side wall of the pull rod 2 inserted into the shaft hole is provided with a positioning pin 21, and the side wall of the connecting shaft 3 is provided with a guide groove 32 for the positioning pin 21 to slide.

[0028] The guide groove 32 comprises an arc-shaped groove 321 arranged on the circumferential side wall of the connecting shaft 3 and a straight groove 322 extending along the axial direction of the connecting shaft 3 and communicating with the arc-shaped groove 321 and the end face of the connecting shaft 3. The connecting position of the straight groove 322 and the arc-shaped groove 321 can be one end of the arc-shaped groove 321, that is, the guide groove 32 is in a "7" shape structure; or the connecting position of the straight groove 322 and the arc-shaped groove 321 can be the middle position of the arc-shaped groove 321, that is, the guide groove 32 is in a "T" shape structure. In this embodiment, the connecting position of the straight groove 322 and the arc-shaped groove 321 is one end of the arc-shaped groove 321. The inflation head 4 is installed in the shaft hole of the connecting shaft 3, and the inflation head 4 abuts against one end of the pull rod 2 inserted into the shaft hole.

[0029] Preferably, the opening angle of the arc-shaped groove 321 is designed to be 60°-90°, which not only ensures that the positioning pin 21 has enough sliding space, but also avoids the insufficient strength of the connecting shaft 3 due to the opening being too large.

[0030] Further, the pull rod 2 is provided with a shaft shoulder, and when the positioning pin 21 abuts against the side wall of the arc-shaped groove 321, the shaft shoulder abuts against the end face of the connecting shaft 3. The shaft shoulder plays a certain limiting role.

[0031] During installation, the pull rod 2 of the inflation bottle 1 is inserted into the shaft hole of the connecting shaft 3, the positioning pin 21 slides inward along the straight groove 322, and when the positioning pin 21 reaches the arc-shaped groove 321, the pull rod 2 and the connecting shaft 3 are relatively rotated until the positioning pin 21 abuts against the end of the arc-shaped groove 321, and the installation is completed; then the inflation head 4 abuts against one end of the pull rod 2 inserted into the shaft hole, and the communication of the air passage is realized. Then the connecting shaft 3 is rotated by the main shaft, the end of the arc-shaped groove 321 limits the positioning pin 21, and the pull rod 2 rotates with the connecting shaft 3.

[0032] Embodiment two:

[0033] This embodiment is further improved on the basis of embodiment one. Although the structure of the guide groove 32 in embodiment one is listed as two kinds, one is a "7" shape structure and the other is a "T" shape structure; the guide groove 32 in the "7" shape structure can only drive the inflation bottle to rotate in one direction, although the guide groove 32 in the "T" shape structure can drive the inflation bottle to rotate in both directions, but this also increases the opening of the arc-shaped groove 321, thereby causing the insufficient strength of the connecting shaft 3.

[0034] This embodiment realizes the bidirectional driving of the guide groove 32 to rotate the inflation bottle without increasing the opening of the arc-shaped groove 321.

[0035] The connecting position of the straight slot 322 and the arc-shaped slot 321 is located at one end of the arc-shaped slot 321, facilitating smooth transition of the positioning pin 21. The arc-shaped slot 321 is provided with a limiting slot 323 at an end away from the straight slot 322, the limiting slot 323 extends along the axis direction of the connecting shaft 3 and does not communicate with the end surface of the connecting shaft 3, for limiting the sliding range of the positioning pin 21, ensuring the stability of clamping.

[0036] The inflation head 4 is axially slidable along the connecting shaft 3 under the driving of the driving device; when the positioning pin 21 is rotated to the connecting position of the arc-shaped slot 321 and the limiting slot 323, the positioning pin 21 can be pushed into the limiting slot 323 through the pressing action of the inflation head 4, and the limiting slot 323 realizes bidirectional limiting of the positioning pin 21.

[0037] In order to facilitate replacement and maintenance, the positioning pin 21 is provided with a sliding block, and the sliding block is limitingly and slidably arranged in the guide slot 32. The surfaces of the sliding block in contact with the limiting slot 323 are flat surfaces, ensuring sufficient force receiving area and stable contact. Meanwhile, inclined surfaces are arranged between the adjacent flat surfaces of the sliding block, facilitating smooth transition of the sliding block in the guide slot 32 and avoiding jamming caused by incomplete sliding.

[0038] As shown in Figure 4 In order to ensure that the inflation head 4 can stably push the connecting shaft 3, the inflation head 4 comprises an inflation cover 41 and a thimble 42 arranged at the center of the inflation cover 41, one end of the pull rod 2 inserted into the shaft hole is sealingly inserted into the inflation cover 41, and the thimble 42 can be inserted into the air channel of the pull rod 2, realizing rapid inflation of the gas cylinder.

[0039] In order to facilitate observation of the clamping state and necessary maintenance operation, the side wall of the connecting shaft 3 is also provided with an observation hole 33.

[0040] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples, and the changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the present application should also belong to the protection scope of the present application.
