[0041] See also Figures 1-12 .

[0042] This solution discloses a pipe clamp, comprising a clip 1, a shock-absorbing pad set 2, a bolt 3 and a nut 4, wherein:

[0043] There are two clips 1 arranged opposite to each other, and a through hole 5 for the bolt 3 to pass through is opened on the clip 1;

[0044] The shock-absorbing pad group 2 includes a first shock-absorbing pad 21 and a second shock-absorbing pad 22 arranged relatively to each other. An arc-shaped hole 6 that cooperates with the pipeline is provided on the side opposite to the first shock-absorbing pad 21 and the second shock-absorbing pad 22. Specifically, an arc-shaped hole 6 that adapts to the shape of the pipeline is provided on the side opposite to the first shock-absorbing pad 21 and the second shock-absorbing pad 22. An arc-shaped hole 6 that adapts to the shape of the pipeline is provided on the side opposite to the first shock-absorbing pad 21. After the first shock-absorbing pad 21 and the second shock-absorbing pad 22 are fitted together, the two arc-shaped holes 6 are combined to form a circular hole that adapts to the shape of the pipeline. Both the first shock-absorbing pad 21 and the second shock-absorbing pad 22 are provided with a through hole 5 that cooperates with the bolt.

[0045] In this solution, a first clamping portion 7 is provided on the side opposite to the first shock-absorbing pad 21 and the second shock-absorbing pad 22. It should be noted here that the side opposite to the first shock-absorbing pad 21 and the second shock-absorbing pad 22 is the side opposite to the side where the first shock-absorbing pad 21 and the second shock-absorbing pad 22 are in contact. Specifically, the first clamping portion 7 is provided on the side opposite to the first shock-absorbing pad 21 and the second shock-absorbing pad 22, and the first clamping portion 7 is also provided on the side opposite to the first shock-absorbing pad 21. The clip 1 has a second clamping portion 8 that is engaged with the first clamping portion 7. The clip 1 is connected to the first clamping portion 7 of the first shock-absorbing pad 21 via the second clamping portion 8, thereby achieving pre-assembly of the clip 1 and the first shock-absorbing pad 21. The clip 1 is connected to the first clamping portion 7 of the second shock-absorbing pad 22 via the second clamping portion 8, thereby achieving pre-assembly of the clip 1 and the second shock-absorbing pad 22. For the convenience of subsequent description, in this solution, the whole pre-assembled from the clip 1 and the first shock-absorbing pad 21 is named the first whole, and the whole pre-assembled from the clip 1 and the second shock-absorbing pad 22 is named the second whole.

[0046] During transportation and handling, the clip 1 is preassembled with the first shock-absorbing pad 21, and the clip 1 is preassembled with the second shock-absorbing pad 22. The bolt 3 passes through the through holes of the clip 1, the first shock-absorbing pad 21, and the second shock-absorbing pad 22 and cooperates with the nut 4, thereby achieving pre-assembly of the pipe clamp and preventing the pipe clamp structure from being fragmented. When the pipe clamp is fixed to the pipeline, only the bolt 3 and the nut 4 need to be disassembled, and the first and second integral bodies do not need to be disassembled. The first and second integral bodies directly cooperate with the pipeline. Compared with the existing method that requires all parts of the pipe clamp to be disassembled and reassembled, this simplifies the assembly process of the pipe clamp and the pipeline. In this solution, whether during transportation or installation, the clip 1 and the first shock-absorbing pad 21, as well as the clip 1 and the second shock-absorbing pad 22, are always in a pre-assembled state and do not need to be disassembled.

[0047] After the clip 1 is preassembled with the first shock-absorbing pad 21, the through-holes of the clip 1 correspond to and communicate with the through-holes of the first shock-absorbing pad 21. After the clip 1 is preassembled with the second shock-absorbing pad 22, the through-holes of the clip 1 correspond to and communicate with the through-holes of the second shock-absorbing pad 22. After the first and second components are mated to the pipeline, bolts 3 are passed through the through-holes 5 of the first and second components, respectively, and tightened with nuts 4 to secure the pipe clamp to the pipeline.

[0048] like Figure 3-Figure 6 As shown, the through hole 5 opened on the clip 1 and the shock-absorbing pad group 2 is staggered with the arc hole 6 opened on the shock-absorbing pad group 2. The through hole 5 is not connected to the arc hole 6, and the axis of the through hole 5 is perpendicular to the axis of the arc hole 6.

[0049] It should be noted that the first clamping portion 7 on the first and second shock-absorbing pads 21 and 22 and the second clamping portion 8 on the clip 1 do not affect the locking of the clip 1 by the bolt 3 and the nut 4 .

[0050] In some embodiments, the first clamping portion 7 is a clamping slot, such as Figure 3-Figure 5 As shown, the first clamping portion 7 is provided on both sides of the length direction of the first shock-absorbing pad 21 and the second shock-absorbing pad 22, that is, the first shock-absorbing pad 21 and the second shock-absorbing pad 22 each have two clamping slots, and the two clamping slots are arranged opposite to each other, and the notches of the two clamping slots are opposite to each other, wherein the length direction of the first shock-absorbing pad 21 and the second shock-absorbing pad 22 is perpendicular to the axial direction of the arc-shaped hole 6;

[0051] The clip 1 is located between the two card slots. The second engaging portion of the clip 1 may be a card block separately provided on the clip 1 or an edge of the clip 1 corresponding to the position of the card slot.

[0052] The first clamping portion is integrally formed with the first shock-absorbing pad 21 and the second shock-absorbing pad 22 .

[0053] In the embodiment where the second clamping portion 8 is a separately provided clamping block, the clamping block is provided to protrude from the edge of the clip 1, the direction in which the clamping block extends is parallel to the plane where the clip 1 is located, and the clamping blocks are arranged at intervals along the length direction of the clip 1;

[0054] In the embodiment where the second engaging portion 8 is the edge of the clip 1 corresponding to the position of the engaging slot, the edge of the clip 1 is directly engaged with the engaging slot.

[0055] The pipe clamp disclosed in this solution has a clip 1 located between two slots, which are protruding from the surfaces of the first shock-absorbing pad 21 and the second shock-absorbing pad 22. Compared with the prior art method in which the clip 1 is wrapped around the shock-absorbing pad, the width of the clip 1 of the pipe clamp of this solution is relatively reduced, thereby reducing the material consumption of the clip 1; and Figure 3 and Figure 4 As shown, the clip 1 is lower than the surfaces of the first shock-absorbing pad 21 and the second shock-absorbing pad 22 , which reduces the overall volume of the pipe clamp compared to the pipe clamp in the prior art.

[0056] In an embodiment where the second clamping portion 8 is the edge of the clip 1 corresponding to the position of the slot, the first end of the clip 1 in the longitudinal direction is inserted into the slot from the first end in the longitudinal direction of the slot, and the edge of the clip 1 slides along the longitudinal direction of the slot until the first end of the clip 1 is flush with the second end in the longitudinal direction of the slot.

[0057] When the clip 1 slides along the slot, the slot walls that are flush with the end faces of the first shock-absorbing pad 21 and the second shock-absorbing pad 22 have a pressing effect on the clip 1, and the slot walls that are perpendicular to the end faces of the first shock-absorbing pad 21 and the second shock-absorbing pad 22 have a guiding and limiting effect on the movement of the clip 1.

[0058] Optionally, the slot and the clip 1 are clearance-fitted.

[0059] In order to further optimize the above technical solution, one of the clips 1 is fixedly connected to the nut 4 to realize the assembly of the nut 4 and the clip 1. When the pipe clamp is fixed to the pipeline, the nut 4 does not need to be removed from the clip 1.

[0060] like Figure 5 As shown, a nut 4 is fixed on the clip 1 connected to the body, and an ear plate connected to the body is provided on the clip 1 connected to the body. The length of the clip 1 connected to the body is greater than the length of the clip 1 not connected to the body.

[0061] There are many ways to fix the clip 1 and the nut 4, such as welding, bonding or interference fit.

[0062] In this solution, the two clips of the pipe clamp are pre-assembled with the first shock-absorbing pad and the second shock-absorbing pad respectively. After pre-assembly, the through holes of the clips are aligned with the through holes of the first shock-absorbing pad and the second shock-absorbing pad, avoiding problems such as misalignment, skewness, poor alignment and falling off of the clips or shock-absorbing pads during the assembly process. The nut is welded to the clip used for connection to the machine body, and there is no need to fix the nut in position separately during the assembly process, which facilitates and facilitates quick assembly.

[0063] In some embodiments, the first end of the clip 1 in the longitudinal direction has a chamfer 11, and the chamfer 11 is used to reduce the difficulty of inserting the clip 1 into the card slot; and / or,

[0064] The second end of the clip 1 in the longitudinal direction has a folded edge 12 for positioning the clip 1. After the folded edge 12 abuts against the first shock-absorbing pad 21 or the second shock-absorbing pad 22, the through hole of the clip 1 corresponds to the position of the through hole of the first shock-absorbing pad 21 or the second shock-absorbing pad 22.

[0065] like Figure 2 As shown, after the pipe clamp fixes the pipeline, the pipe clamp is arranged in the vertical direction. In this embodiment, the second end of the clip 1 is located above the first end of the clip 1, and the folded edge 12 is used to limit the movement of the clip 1 under the action of gravity, thereby reducing the difficulty of assembling the pipe clamp.

[0066] In related technologies, pipe clamps are usually used to fix the engine's oil inlet and return pipes, water inlet and return pipes, and air pipes. Due to the similar size and shape of the pipes, it is difficult to distinguish the flow direction of gas and liquid in the pipes, and they can only play a fixing role. When used to connect the engine pipes and the vehicle pipes, it is impossible to quickly and intuitively identify the flow direction of gas and liquid in the pipes, which easily leads to the risk of incorrect installation or reverse installation of the pipes.

[0067] In this solution, a direction mark is provided on at least one clip 1 to indicate the flow direction of gas and liquid in the pipeline, which is convenient for quickly connecting the engine pipeline and the vehicle pipeline according to the indication of the direction mark, reducing the risk of wrong installation or reverse installation.

[0068] One of the two clips 1 is connected to the machine body, and the other clip 1 is away from the machine body. Optionally, a direction mark is provided on the clip 1 away from the machine body among the two clips 1 .

[0069] Direction signs can be arrows, text, patterns, etc.

[0070] The directions of the direction marks of the clip 1 corresponding to different pipelines can be equal or unequal. Figure 4 As shown, the first shock-absorbing pad 21 and the second shock-absorbing pad 22 of the pipe clamp each include three shock-absorbing blocks 9 , and the direction marks corresponding to the shock-absorbing blocks 9 at both ends are opposite to the direction marks corresponding to the shock-absorbing block 9 in the middle.

[0071] The direction mark can be provided on the surface of the clip 1 away from the shock-absorbing pad assembly 2 , or on the side surface of the clip 1 .

[0072] The first shock-absorbing pad 21 and the second shock-absorbing pad 22 each include at least two shock-absorbing blocks 9 arranged along the length direction of the clip 1. The first shock-absorbing pad 21 and the second shock-absorbing pad 22 include the same number of shock-absorbing blocks 9. Specifically, the first shock-absorbing pad 21 has several shock-absorbing blocks 9, and the second shock-absorbing pad 22 also has several shock-absorbing blocks 9. The shock-absorbing blocks 9 of the first shock-absorbing pad 21 correspond one-to-one to the shock-absorbing blocks 9 of the second shock-absorbing pad 22.

[0073] Each shock absorbing block 9 has a first clamping portion 7, so that each shock absorbing block 9 can be pre-assembled with the clip 1 through the second clamping portion 8. Optionally, the length of the clip 1 not connected to the body is equal to the sum of the lengths of the shock absorbing blocks 9 included in the first shock absorbing pad 21 and the second shock absorbing pad 22;

[0074] Each damping block 9 has an arc-shaped hole 6. The arc-shaped holes 6 of two damping blocks 9 arranged opposite to each other in a direction perpendicular to the plane where the clip 1 is located are combined to form a pipe hole adapted to the shape of the pipeline.

[0075] Each shock-absorbing block 9 has a through hole 5 that cooperates with the bolt 3, so that each shock-absorbing block 9 can be locked between the two clips 1 by the bolt 3 and the nut 4, or the side walls of two adjacent shock-absorbing blocks 9 that are in contact with each other are provided with an arc groove that cooperates with the bolt 3, and the arc grooves of the two adjacent shock-absorbing blocks 9 are combined to form a through hole 5 that cooperates with the bolt 3.

[0076] In this solution, the first and second shock-absorbing pads 21, 22 are designed as separate structures. This allows the number of shock-absorbing blocks 9 to be selected based on the number of pipes to be secured. Shock-absorbing blocks 9 that match the pipe diameters to be secured can be selected and freely combined to meet the needs of different scenarios. The length of the clamp can also be selected based on the number of shock-absorbing blocks.

[0077] In addition, the first shock-absorbing pad 21 and the second shock-absorbing pad 22 are both designed as split structures, and the shock-absorbing block 9 can be produced in a standardized manner. Compared with the overall setting of the shock-absorbing pad in the related art, it reduces molds and reduces costs.

[0078] The first shock-absorbing pad 21 and the second shock-absorbing pad 22 are made of rubber or plastic. On the basis of ensuring the fixation and limitation of the pipeline, they can also play a role in shock absorption and reduce damage to the pipeline.

[0079] Optionally, the nut is a lock nut.

[0080] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed, and is not intended to limit the present application. For those skilled in the art, various modifications and variations of the present application are possible. The scope of application involved in the present application is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the above-mentioned application concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application.
