DETAILED DESCRIPTION

[0025] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0026] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention. Therefore, the drawings only show the layers related to the present invention rather than being drawn according to the number, shape and size of the layers in actual implementation. In actual implementation, the type, quantity and proportion of each layer may be changed arbitrarily, and the layer layout may also be more complicated.

[0027] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention; however, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details.

[0028] Figure 1 This is a schematic diagram of the unfolded structure of an air pump connecting hose in one embodiment of the utility model. Figure 2 The bottom structure diagram of an air pump connecting hose of the utility model is as follows: Figure 1-Figure 2 As shown, it includes a hose body 1, a first pipe sleeve 2, a second pipe sleeve 3, a first clamping ring 4, a second clamping ring 5, a first joint 6, a second joint 7 and a gas nozzle connector;

[0029] The first sleeve 2 and the second sleeve 3 are respectively arranged at two ends of the hose body 1;

[0030] The first clamping ring 4 and the second clamping ring 5 are respectively sleeved on the first sleeve 2 and the second sleeve 3, so that the first sleeve 2 and the second sleeve 3 are compressed on the end of the hose body 1;

[0031] The first joint 6 and the second joint 7 are respectively arranged on the first pipe sleeve 2 and the second pipe sleeve 3. The first joint 6 is connected to the air pump, and the second joint 6 is detachably connected to the air nozzle connector.

[0032] The first sleeve 2 and the second sleeve 3 are both provided with an insertion end, and the insertion end is tapered; the insertion end of the first sleeve 2 is inserted into one end of the hose body 1, and the insertion end of the second sleeve 3 is inserted into the other end of the hose body 1, and the middle parts of the first sleeve 2 and the second sleeve 3 are both provided with external threads.

[0033] The first clamping ring 4 is sleeved on one end of the hose body 1, the inner wall of one end of the first clamping ring 4 is provided with an internal thread, and the inner wall of the other end of the first clamping ring 4 is provided with a limiting ring, and the limiting ring contacts the outer wall of the hose body 1; the first clamping ring 4 is threadedly connected to the first pipe sleeve 2, so that when the insertion end of the first pipe sleeve 2 is inserted into the hose body 1, one end of the hose body 1 expands and is limited by the limiting ring.

[0034] In the present application, when the first clamping ring 4 is twisted, the threaded structure causes the insertion portion of the first sleeve 2 to drill into the interior of the hose body 1. Since the insertion portion is conical, the deeper it drills, the greater the expansion of one end of the hose body 1 will be. Since the inner wall of the other end of the first clamping ring 4 is provided with a limiting ring, the inner diameter of which is exactly the same as the outer diameter of the hose body 1 in a natural state, after one end of the hose body 1 expands, on the one hand, the first clamping ring 4 cannot be detached from one end of the hose body 1, and the first sleeve 2 threadedly connected to the first clamping ring 4 cannot be detached from one end of the hose body 1, thereby ensuring the stability of the connection; on the other hand, the expanded hose body 1 fits tightly with the first sleeve 2, thereby ensuring air tightness.

[0035] The second clamping ring 5 is sleeved on the other end of the hose body 1, the inner wall of one end of the second clamping ring 5 is provided with an internal thread, and the inner wall of the other end of the second clamping ring 5 is provided with a limiting ring, which contacts the outer wall of the hose body 1; the second clamping ring 5 is threadedly connected with the second pipe sleeve 3, so that when the insertion end of the first pipe sleeve 2 is inserted into the hose body 1, one end of the hose body 1 expands and is limited by the limiting ring.

[0036] The principle of the second compression ring 5 compressing and sealing the second sleeve 3 is consistent with the above, and specifically includes:

[0037] When the second clamping ring 5 is turned, the threaded structure causes the insertion portion of the second sleeve 3 to drill into the interior of the hose body 1. Since the insertion portion is conical, the deeper it drills, the greater the expansion of one end of the hose body 1 will be. Since the inner wall of the other end of the second clamping ring 5 is provided with a limiting ring, the inner diameter of which is exactly the same as the outer diameter of the hose body 1 in a natural state, after one end of the hose body 1 expands, on the one hand, the second clamping ring 5 cannot be detached from one end of the hose body 1, and the second sleeve 3 threadedly connected to the second clamping ring 5 cannot be detached from one end of the hose body 1, thereby ensuring the stability of the connection; on the other hand, the expanded hose body 1 fits tightly with the second sleeve 3, thereby ensuring air tightness.

[0038] In one embodiment of the present application, a first outer limiting ring 21 is further provided on the outer wall of the first sleeve 2, a first inner limiting ring 61 is provided on the inner wall of the first joint 6, and the first outer limiting ring 21 is arranged on the outer side of the first inner limiting ring 61 to limit the first joint 6 on the first sleeve 2.

[0041] like Figure 3 As shown, various types of gas nozzle connectors can be provided in the present application to be suitable for different gas nozzle types.

[0042] When the second joint 7 is threadedly connected to the gas nozzle connector, the end of the second sleeve 3 contacts the gas nozzle connector, and a sealing ring 8 is provided between the end of the second sleeve 3 and the gas nozzle connector. The first joint 6 is threadedly connected to the outlet of the air pump, and the connection between the first joint 6 and the outlet of the air pump is sealed by a sealing gasket to ensure the overall sealing.
