[0027] Compared with the prior art, a plurality of grooves are provided on the inner surfaces of the fixed tube clamp body 10 and the movable tube clamp body 20, and the first elastic pad 31 and the second elastic pad 32 are respectively injection molded on the inner surfaces of the fixed tube clamp body 10 and the movable tube clamp body 20 through an injection molding process, so that a plurality of protrusions corresponding to and matching the grooves can be formed on the back sides of the first elastic pad 31 and the second elastic pad 32 after injection molding, thereby improving the connection firmness between the first elastic pad 31 and the fixed tube clamp body 10, and between the second elastic pad 32 and the movable tube clamp body 20, and preventing the elastic pad 3 from detaching.

[0028] Furthermore, in order to improve the support and fixation effect on the wiring harness pipeline, the inner surfaces of the first elastic pad 31 and the second elastic pad 32 are both provided with anti-slip grooves.

[0029] According to one embodiment of the present invention, in order to make the fixed pipe clamp 1 and the movable pipe clamp 2 cooperate with each other to clamp and fix the wiring harness pipeline, the wiring harness pipe clamp also includes a flexible connecting belt 4 and a quick connection structure 5, and the two ends of the flexible connecting belt 4 are respectively fixedly connected to one end of the fixed pipe clamp body 10 and one end of the movable pipe clamp body 20; the quick connection structure 5 is used to realize the quick connection of the other end of the fixed pipe clamp body 10 and the other end of the movable pipe clamp body 20.

[0030] Specifically, the quick connection structure 5 includes a buckle 51 and a buckle 52 that match each other. The buckle 51 is fixedly arranged at one end of the movable pipe clamp body 20 away from the flexible connecting belt 4, and the buckle 52 is fixedly arranged at one end of the fixed pipe clamp body 10 away from the flexible connecting belt 4.

[0031] It can be understood that the buckle 51 and the undercut 52 cooperate with each other to realize the rapid closing and opening of the fixed pipe clamp 1 and the movable pipe clamp 2, so that the operation of the wire harness pipe clamp in this solution is very fast and convenient when in use. It should be noted that the opening and closing of the wire harness pipe clamp in this solution by the cooperation of the buckle 51 and the undercut 52 is only a preferred embodiment of this solution. In other embodiments, it can also be realized by other means, such as bolts, teeth, etc.

[0032] According to an embodiment of the present invention, in order to avoid the harness pipe from directly contacting the buckle 51 and damaging the buckle 51 after the harness pipe clamp in this solution is closed, as shown in FIG. Figure 2The figure shows a schematic diagram of the structure of the wire harness pipe clamp in the closed state in this embodiment; the fixed pipe clamp 1 also includes a stop arm 11 fixedly arranged on the outside of the fixed pipe clamp body 10 and fixedly connected thereto, and a buckle groove for accommodating the buckle 51 is formed between the stop arm 11 and the outer surface of the fixed pipe clamp body 10; the undercut 52 is fixedly arranged at the top end of the stop arm 11.

[0033] It can be understood that since the buckle 51 is generally elastic, the strength of the buckle 51 is relatively small. By fixing the stop arm 11 fixedly connected to the fixed pipe clamp body 10 on the outside of the fixed pipe clamp body 10, and forming a buckle groove for accommodating the buckle 51 between the stop arm 11 and the outer surface of the fixed pipe clamp body 10, when the movable pipe clamp 2 is closed, the buckle 51 is received in the buckle groove, which can prevent the clamping force from being directly applied to the buckle 51 and causing damage to the buckle 51, thereby protecting the buckle 51.

[0034] Furthermore, in order to improve the strength of the buckle 51 , reinforcing ribs 50 are provided on the inner side and / or the outer side of the buckle 51 .

[0035] According to an embodiment of the present invention, in order to improve the strength of the barrier arm 11, the fixed pipe clamp 1 further includes a reinforcing spring sheet 12 fixedly connected between the barrier arm 11 and the fixed pipe clamp body 10, and the reinforcing spring sheet 12 is located on one side of the buckle groove. Specifically, the reinforcing spring sheet 12 is a V-shaped or U-shaped reinforcing spring sheet.

[0036] It can be understood that the reinforcing spring piece 12 can support the barrier arm 11 without affecting the elasticity of the barrier arm 11 itself, thereby improving the strength of the barrier arm 11 .

[0037] According to one embodiment of the present invention, in order to prevent the buckle 51 from shaking along the axial direction of the pipe clamp and disengaging from the undercut 52, the fixed pipe clamp 1 also includes a first limit block 13 fixedly arranged on the other side of the buckle groove, and the first limit block 13 is fixedly connected to the fixed pipe clamp body 10 or the stop arm 11.

[0038] It can be understood that the first limiting block 13 and the reinforcing spring sheet 12 can stop the buckle 51 from both sides of the buckle groove respectively, so as to prevent the buckle 51 from being separated from the buckle groove along the axial direction of the pipe clamp due to shaking.

[0039] According to one embodiment of the present invention, in order to further prevent the buckle from being detached from the undercut 52 due to shaking, the movable pipe clamp 2 also includes a second limit block 21 fixedly arranged on the movable pipe clamp body 20 near one end of the flexible connecting belt 4, and the height of the second limit block 21 is less than the thickness of the second elastic pad 32.

[0040] It can be understood that the second limit block 21 can cooperate with the side wall of the fixed pipe clamp body 10, so as to prevent the buckle 51 from being separated from the undercut 52 due to the axial sliding of the movable pipe clamp body 20 relative to the fixed pipe clamp body 10.

[0041] Furthermore, in order to prevent the second limit block 21 from interfering with the fixed pipe clamp 1 when the fixed pipe clamp 1 and the movable pipe clamp 2 are closed, an anti-interference groove 14 matching the second limit block 21 is provided at one end of the fixed pipe clamp body 10 close to the flexible connecting belt 4.

[0043] It can be understood that the plug connector 61 can cooperate with the sheet metal hole on the vehicle body, so as to fix the clamped wiring harness on the vehicle body sheet metal, and the elastic claws on the plug connector 61 can prevent the plug connector 61 from being detached from the body sheet metal hole due to shaking.

[0044] According to an embodiment of the present invention, in order to prevent dust from entering the installation space of the wiring harness, the fastening connector 6 further includes an elastic dustproof disc 62 fixedly arranged at the root of the plug connector 61. Specifically, the elastic dustproof disc 62 is a trumpet-shaped elastic dustproof disc made of rubber.

[0045] It can be understood that by fixing the dustproof plate 62 at the root of the plug connector 61, when the plug connector 61 is inserted into the sheet metal hole of the vehicle body, the dustproof plate 62 can completely cover the sheet metal hole, thereby preventing external dust from entering the installation space of the wiring harness, and maintaining the cleanliness of the wiring harness installation space, so that the wiring harness has better working performance.

[0046] To sum up, in a wire harness tube clamp provided by an embodiment of the utility model, the elastic pad 3 is injection molded on the inner surfaces of the fixed tube clamp body 10 and the movable tube clamp body 20 through an injection molding process, and since the inner surfaces of the fixed tube clamp body 10 and the movable tube clamp body 20 are provided with a plurality of grooves, after the elastic pad 3 is injection molded, a plurality of protrusions corresponding to the grooves and cooperating with each other are formed on the back of the elastic pad 3, thereby ensuring the firmness of the connection between the elastic pad 3 and the fixed tube clamp 1 and the movable tube clamp 2, and preventing the elastic pad 3 in the fixed tube clamp 1 and the movable tube clamp 2 from detaching.
