[0002] At present, in the field of work that relies on air belts to transmit high-pressure gas, the connection of the air belt mainly relies on the traditional method of plug-in joints and wire bundling. This method not only requires the use of professional tools for operation, but also during the operation process, due to the influence of factors such as dragging and gas pressure changes on the air belt, it is easy to have problems such as loose binding and falling off of the air belt connection joint. Once the joint falls off, it will cause gas leakage, which will not only affect work efficiency, but may also cause serious safety accidents. Therefore, the existing technical solutions have obvious deficiencies in the stability of the air belt connection and the convenience of operation, and a new type of air belt joint technology is urgently needed to solve these problems.

[0006] Furthermore, a threaded hole is provided on the connecting portion, and a diameter of the threaded hole is slightly larger than a diameter of the valve seat.

[0007] Furthermore, the outer shell is movably sleeved on the outer surface of the clamping portion and abuts against each buckle, and the outer shell is internally provided with a push spring abutting against the screw-connecting portion.

[0008] Furthermore, a return spring is provided at the bottom of the valve seat, and the return spring is installed on the inner wall surface of the threaded portion.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] The utility model discloses a special quick connector for air belts, which is provided with a clamping part so that the air belt can be clamped on the clamping part, and a connecting part is provided on the screw connection part so as to connect another air belt, thereby connecting two air belts conveniently and quickly.

[0019] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0020] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "back" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] The present embodiment relates to a special quick connector for air belts, which is provided with a clamping part so that the air belt can be clamped on the clamping part, and a connecting part is provided on the threaded part to facilitate connecting another air belt, thereby conveniently and quickly connecting two air belts.

[0023] Based on the above design concept, an exemplary structure of the special quick connector for air belt of this embodiment is as follows: Figure 1-5 As shown, it mainly includes a clamping part 1, a screw-connecting part 2 and an outer shell 4, the outer shell 4 is movably connected to the clamping part 1, the clamping part 1 and the screw-connecting part 2 are cast as one piece, the clamping part 1 and the screw-connecting part 2 are both hollow cylinders, the clamping part 1 is provided with two buckle holes 5 on the outer surface of the spacer ring, and a buckle 6 is provided in each buckle hole 5, a valve seat 8 is provided in the clamping part 1, and an air inlet 9 connected to the inside of the clamping part 1 is provided on the valve seat 8, and the screw-connecting part 2 is threadedly connected with the connecting part 3.
