Description
Technical Field
[0001] This application relates to the field of clamp technology, and in particular to an integrated clamp gasket. Background Technology
[0002] The exhaust pipe of a car is located at the bottom of the vehicle and serves as the passage for exhaust gases from the engine. A typical car exhaust pipe consists of a first exhaust pipe and a second exhaust pipe. One end of the first exhaust pipe has a flange, and the side wall of the second exhaust pipe has a protrusion that engages with the flange. A clamp is placed on the outer periphery between the first and second exhaust pipes. Before installing the clamp, a gasket must be placed between the first and second exhaust pipes. The installation steps for the first and second exhaust pipes are as follows: first, the gasket must be installed onto the first or second pipe; then, the second pipe is inserted into the first pipe; finally, the clamp is fitted onto the connection and tightened. This process is inefficient and carries the risk of the gasket being missing during installation, reducing the seal between the first and second exhaust pipes. Utility Model Content
[0003] The purpose of this utility model is to provide an integrated clamp gasket to address the defects and shortcomings of the existing technology.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: The device includes a clamp, a mounting washer, a threaded rod, and a nut. The mounting washer is located inside the clamp. One end of the threaded rod is rotatably connected to one end of the clamp, and the other end of the threaded rod passes through the other end of the clamp. The nut is threadedly connected to the periphery of one end of the threaded rod. The mounting washer includes a sealing gasket, a deformable part, and a pressure plate. One end of the deformable part is connected to the outer peripheral sidewall of the sealing gasket, and one end of the pressure plate is located at the other end of the deformable part. When the clamp is tightened, the pressure plate can bend toward the sealing gasket.
[0005] Preferably, the mounting pad further includes a locking piece, one end of which is evenly disposed on the peripheral sidewall of the deformed part, and the other end of which is bent, with the bending direction of the locking piece being opposite to the bending direction of the pressure plate.
[0006] Preferably, the locking piece includes a locking part and a sliding part, one end of the sliding part is provided with one end of the locking part and bends outward, and the bending direction of the locking part is opposite to the bending direction of the pressure plate.
[0007] Preferably, the inner wall of the hoop is in the shape of an arc groove, and the deformable part is close to the inner wall of the hoop.
[0008] Preferably, the pressure plate has a clamping block.
[0009] Preferably, the sidewall of the sealing gasket is provided with sealing ribs in the circumferential direction.
[0010] Preferably, the peripheral sidewall of the hoop is provided with a top plate, and the top plate is arranged correspondingly to the pressure plate.
[0011] In summary, this application includes at least one of the following beneficial technical effects: 1. When assembling the first exhaust pipe and the second exhaust pipe, first put the clamp on the second exhaust pipe, then place the sealing gasket on the boss of the second exhaust pipe, then put one end of the first exhaust pipe on the outer peripheral wall of one end of the second exhaust pipe and abut against the sealing rib, then tighten the nut to pull the threaded rod to tighten the clamp, then the top plate of the clamp bends the pressure plate, so that the top block of the pressure plate presses against the flange of the first exhaust pipe, connecting the first exhaust pipe and the second exhaust pipe, which improves the efficiency of assembling exhaust pipes; 2. When the clamp is placed on the second exhaust pipe, the locking piece is fastened and fixed to the peripheral wall of the boss, so that the clamp is fixed on the second exhaust pipe, which improves the stability between the clamp and the second exhaust pipe.

[0014] The present invention will be further described below with reference to the accompanying drawings.
[0015] This application discloses an exhaust pipe.
[0016] Reference Figure 1 and Figure 2It includes a first exhaust pipe 1, a second exhaust pipe 2 and a clamp 3. One end of the first exhaust pipe 1 has an outwardly inclined flange 4. The outer peripheral sidewall of the second exhaust pipe 2 is integrally provided with a boss 5. The longitudinal section of the boss 5 is "V" shaped. The clamp 3 is located between the flange 4 and the boss 5.
[0017] The clamp 3 includes a clamp band 6, a mounting washer 7, a threaded rod 8, and a nut 9. The clamp band 6 is arc-shaped, and its longitudinal section is "C"-shaped, meaning that the inner sidewall of the clamp band 6 is an arc groove. One end of the threaded rod 8 is rotatably connected to one end of the clamp band 6, and the threaded rod 8 slides through the other end of the clamp band 6. The nut 9 is threadedly connected to the circumferential sidewall of one end of the threaded rod 8, and one end of the nut 9 abuts against the sidewall of one end of the clamp band 6.
[0018] Reference Figure 4 and Figure 5 The mounting gasket 7 includes a sealing gasket 10, multiple deformable parts 11, multiple locking pieces 12, and multiple pressure plates 13. One end of each of the multiple deformable parts 11 is uniformly and integrally disposed on the outer peripheral sidewall of the sealing gasket 10. The locking pieces 12 are located between two adjacent deformable parts 11. One end of each of the multiple locking pieces 12 is uniformly and integrally disposed on the outer peripheral sidewall of the sealing gasket 10. The deformable parts 11 and the locking pieces 12 are arranged in opposite directions. One end of the pressure plate 13 is integrally disposed on the outer end face of the deformable part 11.
[0019] The inner circumferential sidewall of the sealing gasket 10 is bent to form a sealing rib 15, which protrudes upward and has a circular longitudinal section. When the first exhaust pipe 1 and the second exhaust pipe 2 approach each other, they will press the sealing rib 15 together. Subsequently, the sealing rib 15 deforms, which increases the contact area between the upper end face of the sealing rib 15 and the flange 4, thereby improving the sealing performance between the first exhaust pipe 1 and the second exhaust pipe 2.
[0020] The sidewall of the pressure plate 13 is die-cast inward to form a clamping block 16, which can press against the sidewall of the flange 4. The clamp 3 is put on the second exhaust pipe 2, and then the sealing gasket 10 is placed on the boss 5 of the second exhaust pipe 2. Then, one end of the first exhaust pipe 1 is put on the outer peripheral sidewall of one end of the second exhaust pipe 2 and abuts against the sealing gasket 10. Then, the nut 9 is turned, thereby pulling the threaded rod 8 to tighten the clamp 6. Then, the top plate 19 of the clamp 6 bends the pressure plate 13, so that the clamping block 16 of the pressure plate 13 presses against the flange 4 of the first exhaust pipe 1, so that the first exhaust pipe 1 and the second exhaust pipe 2 are connected.
[0021] Reference Figure 2 and Figure 3 The locking piece 12 includes a locking part 17 and a sliding part 18. One end of the locking part 17 is integrally provided on the outer side wall of the sealing gasket 10, and one end of the sliding part 18 is integrally provided on the other end of the locking part 17. The longitudinal section of the locking piece 12 is V-shaped, and the locking part 17 is fastened and fixed to the side wall of the boss 5.
[0022] The sidewall of the hoop 6 is uniformly and integrally provided with multiple top plates 19, and the multiple top plates 19 are correspondingly arranged with multiple pressure plates 13. One end of the top plate 19 is provided with a limiting groove, and the sidewall of the pressure plate 13 is embedded in the limiting groove.
[0023] The mounting gasket 7 includes a sealing gasket 10, multiple locking pieces 12, multiple deformable parts 11, and multiple pressure plates 13. The deformable parts 11 are inserted into the clamp 6 to fix the mounting gasket 7 to the clamp 3. The locking pieces 12 are inserted into the first exhaust pipe 1 to fix the first pipe 1 to the mounting gasket 7.
[0024] The overall system installation efficiency has been significantly improved, reducing the number of steps from four to two. The sealing rib 15 completely eliminates the risk of missing gaskets. During installation, the sealing rib 15 is more centered on the sealing surface, which facilitates uniform pressure on the sealing rib 15 and improves sealing performance.
[0025] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
