[0034] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0035] The clamp assembly 1 according to an embodiment of the present utility model is described below with reference to the accompanying drawings.

[0036] like Figure 1-Figure 3 As shown, the clamp assembly 1 according to the embodiment of the utility model includes a clamp 100 , a fastener 200 and a heat-resistant anti-slip component 300 .

[0037] The clamp 100 includes a clamp body 110 extending in an arc shape, and a first mounting ear 120 is provided at one end of the clamp body 110. The fastener 200 includes a threaded portion 210 and a stopper 220. The threaded portion 210 is passed through the first mounting ear 120 and the stopper 220 is stopped at the first mounting ear 120. The heat-resistant anti-slipping member 300 is sleeved on the threaded portion 210 and is stopped at a side of the first mounting ear 120 that is away from the stopper 220. The heat-resistant anti-slipping member 300 is only allowed to move in the direction close to the stopper 220 along the axial direction of the threaded portion 210 to prevent the fastener 200 from being separated from the first mounting ear 120.

[0038] For example, the fastener 200 may be a bolt, and the heat-resistant anti-slip component 300 may be made of a high-temperature resistant metal material.

[0039] According to the clamp assembly 1 of the embodiment of the utility model, the threaded portion 210 is passed through the first mounting ear 120 and the stop portion 220 is stopped at the first mounting ear 120, and the heat-resistant anti-slip component 300 is sleeved on the threaded portion 210 and stopped at the side of the first mounting ear 120 that is away from the stop portion 220. In this way, the stop portion 220 can be stopped at one side of the first mounting ear 120, and the anti-slip component can be connected to the threaded portion 210 and stopped at the other side of the first mounting ear 120, thereby preventing the fastener 200 from detaching from the first mounting ear 120, which is convenient for transportation. When assembling the clamp assembly 1, the fastener 200 is passed through the second mounting ear 130 at the other end of the hoop body 110 and connected to the second mounting ear 130, thereby realizing the assembly of the clamp assembly 1, which is convenient for assembly in a workshop.

[0040] In addition, the heat-resistant anti-slipping component 300 is only allowed to move along the axial direction of the threaded portion 210 toward the direction approaching the stop portion 220 to prevent the fastener 200 from disengaging from the first mounting ear 120. That is to say, the heat-resistant anti-slipping component 300 cannot move along the axial direction of the threaded portion 210 toward the direction away from the stop portion 220. In this way, along the axial direction of the threaded portion 210, the heat-resistant anti-slipping component 300 can prevent the threaded portion 210 from moving toward the direction approaching the stop portion 220, that is, prevent the fastener 200 from moving in the direction of disengaging from the first mounting ear 120, so that the heat-resistant anti-slipping component 300 and the stop portion 220 can be used to clamp the first mounting ear 120 to fix the fastener 200 to the first mounting ear 120 to prevent the fastener 200 from disengaging from the first mounting ear 120.

[0041] In addition, the heat-resistant anti-slipping component 300 can be moved along the axial direction of the threaded portion 210 toward the direction close to the stop portion 220. In this way, the heat-resistant anti-slipping component 300 can be moved along the axial direction of the threaded portion 210 toward the direction close to the first mounting ear 120, so that the heat-resistant anti-slipping component 300 can be assembled into place, so that the heat-resistant anti-slipping component 300 and the stop portion 220 can be used to clamp the first mounting ear 120, thereby limiting the fastener 200. Moreover, when the clamp assembly 1 is subsequently assembled, the first mounting ear 120 and the second mounting ear 130 at both ends of the clamp 100 are fitted together, and the second mounting ear 130 can push the heat-resistant anti-slipping component 300 to move in the direction close to the first mounting ear 120, thereby avoiding the heat-resistant anti-slipping component 300 from interfering with the assembly of the first mounting ear 120 and the second mounting ear 130, so as to facilitate the assembly and connection of the clamp assembly 1.

[0042] In addition, by making the heat-resistant anti-slip component 300 of a high-temperature resistant metal material, the heat-resistant anti-slip component 300 can be prevented from melting. For example, when the clamp assembly 1 is used to fix the exhaust pipe, the exhaust temperature is high, causing the temperature of the heat-resistant anti-slip component 300 to rise, but the heat-resistant anti-slip component 300 will not melt, thereby avoiding the problem of smoke and unpleasant odor generated by the melting of the heat-resistant anti-slip component 300.

[0043] In this way, the exhaust device according to the embodiment of the utility model can prevent the fastener 200 from detaching from the first mounting ear 120, which is convenient for the subsequent assembly of the clamp assembly 1, and the heat-resistant anti-detachment component 300 is not easy to melt, effectively avoiding problems such as melting to produce smoke or unpleasant odor.

[0044] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the heat-resistant anti-slipping member 300 includes a main body 310 and anti-slipping teeth 320 .

[0045] The main body 310 is sleeved on the threaded portion 210 , and the anti-slip teeth 320 are connected to the main body 310 and cooperate with the outer circumference of the threaded portion 210 to prevent the heat-resistant anti-slip component 300 from moving in the axial direction of the threaded portion 210 away from the stopper 220 .

[0046] In this way, the main body 310 can be sleeved on the threaded portion 210 to assemble the heat-resistant anti-slipping component 300 onto the fastener 200, and the anti-slipping teeth 320 and the threaded portion 210 can be used to cooperate. For example, the anti-slipping teeth 320 can be used to abut against the threaded portion 210 or have an interference fit with the threaded portion 210, thereby preventing the heat-resistant anti-slipping component 300 from moving along the axial direction of the threaded portion 210 away from the stop portion 220. After the heat-resistant anti-slipping component 300 is assembled in place, the main body 310 can stop at the first mounting ear 120. At this time, the first mounting ear 120 stops the main body 310, and the anti-slipping teeth 320 limit the threaded portion 210, thereby preventing the fastener 200 from separating from the first mounting ear 120.

[0047] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, there are a plurality of anti-slip teeth 320 , which are connected to the inner side of the main body 310 and arranged at intervals along the circumference of the main body 310 .

[0048] By providing a plurality of anti-slip teeth 320, it is helpful to increase the clamping force of the heat-resistant anti-slip component 300 on the threaded portion 210, thereby increasing the connection strength between the heat-resistant anti-slip component 300 and the threaded portion 210, so that the heat-resistant anti-slip component 300 can be more reliably used to limit the fastener 200, and the cooperation between the threaded portion 210 and the heat-resistant anti-slip component 300 is not easy to fail, which effectively prevents the fastener 200 from detaching from the first mounting ear 120.

[0049] It should be noted that, for different specifications of fasteners 200, the number of anti-slip teeth 320 can also be adjusted according to actual conditions. For example, when the fastener 200 is larger, the number of anti-slip teeth 320 can be arranged to be larger, so as to improve the matching strength between the heat-resistant anti-slip component 300 and the threaded part 210, and to more reliably limit the fastener 200 to prevent the fastener 200 from detaching from the first mounting ear 120.

[0050] In some specific embodiments of the present invention, the inner diameter of the main body 310 is not less than the outer diameter of the threaded portion 210 , and the anti-slip teeth 320 and the threaded portion 210 are interference fit.

[0051] For example, the inner diameter of the main body 310 can be slightly larger than the outer diameter of the threaded portion 210. With this arrangement, the threaded portion 210 can be relatively easily inserted into the main body 310, and the heat-resistant anti-slip component 300 can be pushed along the axial direction of the threaded portion 210 toward the stop portion 220 to assemble the heat-resistant anti-slip component 300 into place, and the anti-slip teeth 320 can hold the threaded portion 210 tightly. When the heat-resistant anti-slip component 300 is installed in place, the heat-resistant anti-slip component 300 can use the holding force of the anti-slip teeth 320 and the threaded portion 210 to fix the heat-resistant anti-slip component 300 and the threaded portion 210, and the heat-resistant anti-slip component 300 will not detach from the fastener 200, and the heat-resistant anti-slip component 300 and the first mounting ear 120 can be used for stopping to limit the fastener 200 from detaching from the first mounting ear 120.

[0052] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the anti-slipping tooth 320 is configured as a sheet and is disposed on the side of the main body 310 facing away from the stopper 220, and the angle between the anti-slipping tooth 300 and the main body 310 is greater than 90°. In other words, the anti-slipping tooth 320 is inclined toward the central axis of the heat-resistant anti-slipping member 300 away from the stopper 220 along the axial direction of the heat-resistant anti-slipping member 300.

[0053] With this arrangement, the inner diameter of the end of the anti-slip tooth 320 close to the stop portion 220 can be larger, while the inner diameter of the end of the anti-slip tooth 320 away from the stop portion 220 can be smaller, that is, the clamping force between the end of the anti-slip tooth 320 away from the stop portion 220 and the threaded portion 210 is greater.

[0054] Preferably, the end of the anti-slipping tooth 320 close to the stopper 220 can be clearance-matched with the outer peripheral surface of the threaded portion 210, and the end of the anti-slipping tooth 320 away from the stopper 220 can be interference-matched with the threaded portion 210. In this way, on the one hand, the anti-slipping tooth 320 can be used to cooperate with the outer peripheral surface of the threaded portion 210 to achieve the fixation of the heat-resistant anti-slipping member 300 and the threaded portion 210, thereby preventing the heat-resistant anti-slipping member 300 from being separated from the threaded portion 210, thereby preventing the fastener 200 from being separated from the first mounting ear 120. On the other hand, when the heat-resistant anti-slipping member 300 moves toward the direction close to the stopper 220, the anti-slipping tooth 320 can allow the heat-resistant anti-slipping member 300 to move along the axial direction of the threaded portion 210, which is convenient for the assembly of the heat-resistant anti-slipping member 300 and the threaded portion 210, so that the heat-resistant anti-slipping member 300 can be installed at any position of the threaded portion 210.

[0055] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the side of the anti-slip tooth 320 facing the threaded portion 210 is configured as an arc surface matched with the threaded portion 210 .

[0056] In this way, the side of the anti-slip tooth 320 facing the threaded part 210 can be adapted to the threaded part 210, which is beneficial to increase the contact area between the anti-slip tooth 320 and the threaded part 210, further improves the matching strength between the anti-slip tooth 320 and the threaded part 210, and the connection strength between the heat-resistant anti-slip part 300 and the threaded part 210 is higher.

[0057] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the outer periphery of the main body 310 is provided with an anti-scratch portion 311. The anti-scratch portion 311 can be provided at the edge of the main body 310 on the side facing away from the stopper 220, and the anti-scratch portion 311 can be configured as a chamfer, a circular arc surface or other structures capable of removing the edge edges of the main body 310.

[0058] It can be understood that when the heat-resistant anti-slip component 300 is installed on the threaded portion 210 along the axial direction of the threaded portion 210, the heat-resistant anti-slip component 300 needs to be pushed into place from the side of the main body 310 that is away from the stop portion 220. Since the edges of the metal parts are relatively sharp, an anti-scratch portion 311 is provided on the edge of the main body 310 that is away from the stop portion 220. This can avoid scratching hands when assembling the heat-resistant anti-slip component 300 and the fastener 200, thereby facilitating assembly and increasing operational safety.

[0059] In some specific embodiments of the present invention, Figure 1As shown, the other end of the hoop body 110 is provided with a second mounting ear 130, and the fastener 200 is passed through the first mounting ear 120 and the second mounting ear 130; wherein, when the first mounting ear 120 and the second mounting ear 130 are abutted, an accommodation gap is defined between the first mounting ear 120 and the second mounting ear 130, and the heat-resistant anti-slip component 300 is located in the accommodation gap.

[0060] Among them, a nut 400 can be provided on the side of the second mounting ear 130 facing away from the first mounting ear 120. After the fastener 200 passes through the first mounting ear 120 and the second mounting ear 130 in sequence, the threaded portion 210 of the fastener 200 can be threadedly matched with the nut 400, thereby connecting and fixing the first mounting portion and the second mounting portion together.

[0061] In this way, when the clamp 100 is assembled, the heat-resistant anti-dropping member 300 will not interfere with the first mounting ear 120 or the second mounting ear 130 , and will not affect the connection between the first mounting ear 120 and the second mounting ear 130 .

[0062] In addition, it should be noted that the hoop body 110 can be divided into two parts, and the two parts are connected by a connecting bridge 140. The connecting bridge 140 can be deformed so that the first mounting ear 120 and the second mounting ear 130 can be moved away from or closer to each other, so as to facilitate the fixing and disassembly of the clamp 100.

[0063] The exhaust device according to the embodiment of the utility model is described below with reference to the drawings, and the exhaust device includes an exhaust pipe and a clamp assembly 1 according to the above embodiment of the utility model, and the clamp assembly 1 is connected to the outer peripheral surface of the exhaust pipe. For example, the clamp assembly 1 can be used to connect the exhaust pipe and the supercharger.

[0064] According to the exhaust device of the embodiment of the utility model, by utilizing the clamp assembly 1 according to the above embodiment of the utility model, it is possible to prevent the fastener 200 from being separated from the first mounting ear 120, thereby facilitating the subsequent assembly of the clamp assembly 1, and the heat-resistant anti-detachment component 300 is not easy to melt, thereby effectively avoiding problems such as smoke or unpleasant odor caused by melting.

[0065] A vehicle according to an embodiment of the present invention will be described below with reference to the accompanying drawings. The vehicle includes the clamp assembly 1 according to the above embodiment of the present invention or the exhaust device according to the above embodiment of the present invention.
