Preferably, a through hole is formed in the bottom of the rectangular caulking groove, and the clamping pin is close to the rear edge of the through hole. The through hole enables the elastic deformation of the clamping pin to be larger, the circular plate is easier to insert into the rectangular embedded groove and clamp with the clamping pin, and the circular plate is easier to take out from the rectangular embedded groove by pressing the wedge-shaped barb of the clamping pin.

Preferably, the one end of the opening of the ring pipe clamp is provided with a clamping part, the other end of the opening of the ring pipe clamp is provided with a clamping hook which can be inserted into the clamping part and clamped with the clamping part, the front side of the clamping part is provided with an avoiding notch, and the front side of the clamping hook is provided with a limit stop matched with the avoiding notch. The limiting stop block can be used for axially limiting the clamping part, so that the clamping part and the clamping hook are prevented from relatively moving in the axial direction.

In the utility model, the first pipe clamp adopts an open structure and can be clamped with the brake vacuum pipe, and the second pipe clamp adopts a closed structure and can be clamped with a pipeline (such as a heating and ventilation water inlet pipe) near the brake vacuum pipe, so that the brake vacuum pipe is separated from the nearby pipeline, and the interference problem is avoided; the first pipe clamp and the second pipe clamp are connected through clamping of the circular plate and the clamping pin and can rotate mutually, the adjustability is good, the reliability is good, and the first pipe clamp and the second pipe clamp are not easy to fall off; the first pipe clamp and the second pipe clamp can be assembled and disassembled repeatedly, the assembly and the disassembly are convenient, and the reliability of connection of the first pipe clamp and the second pipe clamp cannot be influenced due to repeated assembly and disassembly.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

The separating pipe strap of the automobile brake vacuum pipe as shown in fig. 1 to 5 comprises a first pipe strap 1 and a second pipe strap 2. First pipe strap 1 is integrated into one piece's working of plastics, including open type pipe clamp 11, set up brace table 12 on open type pipe clamp 11 right side, set up cylinder 13 on brace table 12 right side and set up the plectane 14 at cylinder 13 right-hand member, open type pipe clamp 11 is "omega" shape. The second pipe clamp 2 is an integrally formed plastic piece and comprises a circular pipe clamp 21 capable of being opened and a connecting seat 22 arranged on the left side of the circular pipe clamp 21, one end of the opening part of the circular pipe clamp 21 is provided with a clamping part 23, the other end of the opening part of the circular pipe clamp 21 is provided with a clamping hook 24 which can be inserted into the clamping part 23 and clamped with the clamping part 23, the front side of the clamping part 23 is provided with an avoiding gap, the front side of the clamping hook 24 is provided with a limit stop 29 matched with the avoiding gap, the lower part (the part below the opening part) of the circular pipe clamp 21 is subjected to grooving and thinning treatment, a simple rotating shaft is equivalently realized, the circular pipe clamp 21 is divided into two mutually connected parts by the simple rotating shaft, the two parts can mutually rotate around the simple rotating shaft, and pipeline assembly is easier to realize; a clamping groove is formed in the connecting seat 22, the clamping groove is formed by communicating a U-shaped groove opening 25 capable of accommodating the cylinder 13 with a rectangular embedding groove 26 capable of accommodating the circular plate 14, a clamping pin 27 with a wedge-shaped barb is arranged in the rectangular embedding groove 26, a through hole 28 is formed in the bottom of the rectangular embedding groove 26, and the clamping pin 27 is close to the rear edge of the through hole 28; the column 13 is located in the U-shaped slot 25, and the circular plate 14 is inserted into the rectangular caulking slot 26 and is clamped with the clamping pin 27, so that the first pipe clamp 1 and the second pipe clamp 2 are connected and can rotate relatively.
