[0006] In one or more embodiments, the cross-section of the auxiliary pressure strip is semicircular or rectangular.

[0007] In one or more embodiments, the locking mechanism includes a screw, a hexagonal nut, and a fixing seat respectively provided at both ends of the hoop body, and the fixing seat is provided with a through hole for the screw to pass through.

[0008] In one or more embodiments, the locking mechanism further includes an allen key having a cavity for accommodating the screw, and the allen key further includes a hand-held portion.

[0009] In one or more embodiments, the fixing seat and the hoop body are an integral structure.

[0010] In one or more embodiments, a reinforcement strip is formed on the outer wall of the hoop body.

[0011] In one or more embodiments, the hoop body, the reinforcement bar and the fixing seat are all made of stainless steel.

[0012] Compared with the background technology, the utility model has the following effects: the clamp is provided with an inner cushion layer, and a plurality of auxiliary pressure strips are arranged at axial intervals on the inner side surface of the cushion layer, that is, the surface in contact with the outer surface of the water pipe; when the clamp body is tightened, the plurality of auxiliary pressure strips tightly press the outer surface of the water pipe, thereby strengthening the connection firmness at the interface between the water pipe and the faucet or the water pipe.

[0016] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0017] Please see Figure 1-3 The present embodiment provides a fastening type clamp, which includes a clamp body 1 and a locking mechanism for locking the clamp body 1. A cushion layer 2 is provided on the inner side of the clamp body 1. The outer side surface of the cushion layer 2 is bonded to the inner side wall of the clamp body 1. The inner side surface of the cushion layer 2 is formed with a plurality of auxiliary pressure strips 3 which are convex and axially arranged. The present embodiment is provided with three auxiliary pressure strips 3. The number of the auxiliary pressure strips is determined according to the actual size of the clamp. The larger the size of the clamp, the greater the number of the auxiliary pressure strips 3. The auxiliary pressure strips 3 are spaced apart from each other. The auxiliary pressure strips 3 and the cushion layer 2 are an integrally formed structure. Specifically, they can be made of polyurethane rubber material, which has the advantages of high pressure resistance, wear resistance, and aging resistance.

[0018] When the clamp of this embodiment is installed, the clamp body 1 is contracted by tightening the locking mechanism, thereby contracting the cushion layer 2. During the contraction process, multiple auxiliary pressure strips 3 continuously press the interface between the water pipe and the faucet or the water pipe to strengthen the connection firmness and sealing at the interface. In addition, when the water pipe is connected to the faucet, the auxiliary pressure strips play a better effect, because the outer surface of the faucet is provided with circles of grooves, just to facilitate the connection of the water pipe, and the cooperation of the auxiliary pressure strips 3 and these grooves will further strengthen the connection firmness and sealing at the interface. In addition, the clamp body is provided with hemming at the two axial outer sides of the cushion layer, which is used to strengthen the connection tightness between the cushion layer and the clamp body and prevent the cushion layer from loosening.

[0019] The cross section of the auxiliary pressure strip 3 is semicircular or rectangular, and the semicircular or rectangular auxiliary pressure strip can better press the water pipe.

[0020] The locking mechanism includes a screw 4, a hexagonal nut 5 and a fixing seat 6 respectively arranged at both ends of the hoop body 1. The fixing seat 6 is provided with a through hole 61 for the screw 4 to pass through. After the screw 4 passes through the two fixing seats 6, it is connected to the hexagonal nut 5. The hoop body 1 can be tightened by tightening the hexagonal nut 5. This structure is more convenient to install.

[0021] In order to facilitate the user to install, tighten or remove the hoop body 1, the locking mechanism further includes an allen key 7, the allen key 7 is provided with a cavity 71 for accommodating the screw 4, and the allen key 7 is also provided with a hand-held portion 8.

[0022] In order to enhance the structural stability of the fixing seat 6 and the hoop body 1, the fixing seat 6 and the hoop body 1 are an integral structure. A reinforcing strip 9 is formed on the outer wall of the hoop body 1.

[0023] The hoop body 1, the reinforcing strip 9 and the fixing seat 6 are all made of stainless steel. Stainless steel has a large stock volume in the market, is relatively easy to purchase, and has good corrosion resistance.

[0024] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
