DETAILED DESCRIPTION

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the present invention is described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0022] It should be noted that the terms "first", "second", "third", "fourth", etc. in the specification and claims of the utility model are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0023] See also Figure 1 to Figure 2 The utility model provides a double pipe clamp, which is suitable for cooling pipes in the front cabin of an automobile, and is also suitable for other pipes in the automobile, and can improve the NVH of the automobile by isolating and reducing noise. The double pipe clamp in the utility model includes a pipe clamp body 1 and a mounting seat 2, and the pipe clamp body 1 is connected to the mounting seat 2 and is installed on the vibration reduction bracket. Specifically, in a preferred embodiment of the utility model, the vibration reduction bracket is arranged on the front panel in the front cabin of the automobile, and the pipe clamp body 1 and the mounting seat 2 are made of different materials respectively. The pipe clamp body 1 is made of EPDM rubber, the mounting seat 2 is made of PA66 nylon, and the vibration reduction bracket is made of PA66 nylon. The material of the pipe body to be clamped by the pipe clamp body 1 is PA22 nylon. It is easy to understand that the hardness of the pipe clamp body 1, the hardness of the mounting seat 2 and the hardness of the vibration reduction bracket do not have to be the same. In other preferred embodiments of the utility model, the vibration reduction bracket can also be made of other nylon, rubber or similar materials with lower cost but greater hardness than the pipe clamp body 1, as long as it can form a secondary vibration reduction structure with the pipe clamp body 1. In the second embodiment of the utility model, due to the limited layout space in the front cabin of the car, the vibration-damping bracket can be directly assembled with the front panel metal without setting the vibration-damping bracket. Since the hardness of the car sheet metal is much greater than that of rubber and nylon, a small-large hardness relationship is formed between the pipe clamp body 1 and the vibration-damping bracket, which forms a good vibration-damping effect for the pipe to be clamped in the pipe clamp body 1. The double pipe clamp of the utility model uses materials with different hardness to respectively form the pipe clamp body 1 and the mounting seat 2, avoiding the use of traditional two-color injection molding process, reducing costs while optimizing the vibration and noise reduction effect of the double pipe clamp, and improving the NVH of the car.

[0024] Please also read Figure 3, further, the tube clamp body 1 includes a first tube clamp 11, a second tube clamp 12 and a connecting portion 13 located between the first tube clamp 11 and the second tube clamp 12, and the first tube clamp 11, the second tube clamp 12 and the connecting portion 13 are fixedly connected as one. It is easy to understand that the double tube clamp is a fastener used to relatively fix two adjacent pipelines or other tubular parts, so the first tube clamp 11 and the second tube clamp 12 are used to clamp two adjacent tube bodies to be clamped, and the connecting portion 13 is used to connect the first tube clamp 11 and the second tube clamp 12 as one, and also relatively limit the two adjacent tube bodies to be clamped. Since the first tube clamp 11, the second tube clamp 12 and the connecting portion 13 are all made of the first material, in a preferred embodiment of the utility model, the first tube clamp 11, the second tube clamp 12 and the connecting portion 13 are integrally formed, and the first tube clamp 11 and the second tube clamp 12 are bilaterally symmetrical structures, and the two maintain a certain distance according to the preset parameters of the tube clamp body 1 and do not interfere with each other. Specifically, taking the first tube clamp 11 as an example, the first tube clamp 11 is provided with an anti-slip portion 4 and a clamping portion 5, the anti-slip portion 4 includes an anti-slip buckle 41 and an anti-slip groove 42, the anti-slip buckle 41 is used to be inserted into the anti-slip groove 42, and the anti-slip groove 42 is used to prevent the anti-slip buckle 41 from escaping from the anti-slip portion 4; the clamping portion 5 is an inner protrusion arranged at intervals in the first tube clamp 11 and the second tube clamp 12, and the tube clamp body 1 wraps and fixes the tube body to be clamped along the circumferential direction through the clamping portion 5. In a preferred embodiment of the utility model, the first tube clamp 11 has an opening, the anti-dropping portion is located in the opening, the anti-dropping buckle 41 is a wedge-shaped hook, and the anti-dropping groove 42 is configured according to the wedge-shaped hook. The anti-dropping buckle 41 and the anti-dropping groove 42 are both located at the top of the first tube clamp 11. That is to say, when the anti-dropping buckle 41 and the anti-dropping groove 42 are disengaged, the first tube clamp 11 presents a "C"-shaped structure with an opening upward, and the anti-dropping buckle 41 and the anti-dropping groove 42 are respectively located on the two end surfaces of the top thereof. The first tube clamp 11 is in the anti-dropping buckle 41 and the anti-dropping groove When 42 is engaged, it forms a closed "O"-shaped structure, and the anti-slip buckle 41 and the anti-slip groove 42 can gather the parts of the first tube clamp 11 located on both sides of the corresponding opening together; the inner edge of the first tube clamp 11 is provided with a plurality of inner protrusions, and the inner protrusions are arranged in sequence with the same intervals. The first tube clamp 11 is abutted against the tube to be clamped in the first tube clamp 11 through the inner protrusions, and the interval between the inner protrusions will slightly expand and open as the anti-slip buckle 41 and the anti-slip groove 42 are disengaged, and will also gradually shrink and be fixed as the anti-slip buckle 41 and the anti-slip groove 42 are engaged. The pipe clamp body 1 of the utility model realizes effective fixation of the pipe body to be clamped by arranging the anti-slipping part 4 and the clamping part 5. The anti-slipping part 4 can prevent the pipe body to be clamped from escaping or moving from the pipe clamp body 1 during the bumpy driving process. The clamping part 5 can stabilize the contact surface size between the pipe body to be clamped and the pipe clamp body 1, and also make the pipe clamp body 1 adaptable to a variety of pipe bodies to be clamped with similar sizes. In addition, it can also reduce the difficulty of assembling the pipe clamp body 1 to the pipe body to be clamped to a certain extent. The utility model has excellent applicability and adjustability and good economic benefits.

[0025] Further, the connection part 13 is provided with a weight-reducing part 31 for weight reduction and a mounting part 32 for assembling the mounting seat 2. Specifically, in the present embodiment, the weight-reducing part 31 includes a weight-reducing hole, and the mounting part 32 includes a mounting hole. The weight-reducing hole is opened at the bottom of the connection part 13 along the front-to-back direction, and the mounting part 32 is opened at the bottom of the connection part 13 along the up-down direction. The weight-reducing hole and the mounting part 32 are connected in the weight-reducing part 31. Specifically, in a preferred embodiment of the present utility model, the weight-reducing hole is opened along the front-to-back direction and is a through hole. The weight-reducing hole is provided between the first pipe clamp 11 and the second pipe clamp 12. The mounting hole is opened along the up-down direction. The upper end of the mounting hole is connected to the weight-reducing hole, and the lower end opening faces the mounting seat 2. It is easy to understand that the function of the weight reduction part 31 is to remove part of the weight of the pipe clamp body 1 to make it lightweight. Therefore, the size and setting method of the weight reduction hole and the mounting hole can also be adjusted according to the actual situation of the interior space of the front cabin of the car. In some other embodiments of the utility model, the size of the weight reduction hole in the up and down direction is small, and the weight reduction hole is correspondingly set as a single-sided opening in the front and rear directions, or is not a through hole, and the mounting hole can also be correspondingly set to be not connected to the weight reduction hole. The utility model reduces the manufacturing cost of the pipe clamp body 1 by setting the weight reduction part 31 on the connecting part 13. While achieving the lightweight of the double pipe clamp, the weight reduction hole is used to open an additional mounting hole according to the actual situation of the interior space of the front cabin of the car, so as to facilitate the assembly of the mounting seat 2.

The second positioning portion 21b is axially arranged at the bottom of the mounting seat 2 and is integrally formed with the mounting seat 2, the second positioning portion 21b is hollow cylindrical, and the vibration damping bracket positions the mounting seat 2 axially in the vibration damping bracket by extending into the second positioning portion 21b. As mentioned above, due to the limited layout space in the front cabin of the automobile, a vibration damping bracket may not be provided and the mounting base 2 may be directly assembled with the front panel sheet metal. Therefore, the form and shape of the positioning portion may be configured according to whether it is assembled with the vibration damping bracket or the front panel sheet metal and the structure of the vibration damping bracket or the front panel sheet metal. The vibration damping bracket may also be provided with an assembly portion for assembling with the first positioning portion 21a and / or the second positioning portion 21b in accordance with the layout space in the front cabin of the automobile. In the first embodiment of the utility model, the mounting seat 2 is in the shape of a Christmas tree, and the assembly portion is configured as a circular hole corresponding to the columnar first positioning portion 21a, and the size of the circular hole is smaller than the limiting portion 22, so the mounting seat 2 can be inserted into the shock-absorbing bracket to position it circumferentially, and the limiting portion 22 is abutted against the shock-absorbing bracket and limited axially, so as to realize the assembly and fixation between the two; and in the second embodiment of the utility model, the mounting seat 2 is in the shape of a bushing, and the assembly portion is configured as a cylinder corresponding to the hollow cylindrical second positioning portion 21b, so the mounting seat 2 can be sleeved on the cylinder of the front wall sheet metal to position it circumferentially, and the limiting portion 22 is abutted against the front wall sheet metal and limited axially, so as to realize the assembly and fixation between the two. That is to say, the mounting seat 2 of the utility model can be adapted to the corresponding structure in the front cabin of the car through the solid column or hollow cylindrical positioning portion, so as to adapt to various structures in the front cabin of the car, such as: motor, air conditioner, engine, suspension, etc.
