Description

Technical Field

[0001] This utility model relates to the technical field of exhaust pipe connection structure, specifically a connection structure for a vehicle exhaust pipe. Background Technology

[0002] The vehicle exhaust pipe is an important device used for vehicle exhaust. Traditional exhaust pipes are fixed to the vehicle with multiple screws during installation, which reduces disassembly efficiency when the exhaust pipe needs to be removed.

[0003] A search revealed a vehicle exhaust pipe disclosed in Chinese Patent Publication No. CN218093200U. The key technical point is that when the vehicle is not in use for an extended period, activating the drive assembly causes the first slider to slide on the connecting plate towards the drive assembly. The first slider drives the connecting plate to rotate on the mounting base, and the connecting plate drives the second slider to rotate and slide correspondingly within the groove. Simultaneously, the groove is pulled away from the mounting base, causing the dust cover to rotate on the mounting base towards the exhaust pipe body until the dust cover contacts the exhaust pipe body and blocks the exhaust pipe's outlet, preventing rainwater and dust from entering. This solves the problem of existing exhaust pipes becoming clogged due to foreign objects entering the exhaust pipe when not in use for extended periods.

[0004] However, existing technologies do not allow for quick assembly and disassembly of exhaust pipes, hindering their rapid replacement. This application addresses this issue by pressing a first pipe body with a first connector to a second connector. During this process, an elastic plate is inserted along a corresponding slot, then opens until the first and second connectors contact. A rotating wheel then drives a threaded column to rotate on the first pipe body. This causes the connecting column to slide a fixing ring horizontally along a groove, which in turn presses the elastic plate open, enabling quick assembly and disassembly of the exhaust pipe. Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The aforementioned background technology addresses the problem that existing technologies cannot quickly disassemble and assemble exhaust pipes.

[0006] This utility model discloses a connection structure for a vehicle exhaust pipe, comprising a first pipe body and a second pipe body. A rotating wheel is rotatably connected to the outer surface of the first pipe body, and a threaded post is fixedly connected to the outer surface of the rotating wheel. A first connector is fixedly connected to one end of the first pipe body, and the outer surface of the first connector has several slots. A sliding groove is formed on the outer surface of the first pipe body. A connecting post is threadedly connected to the outer surface of the threaded post, and a fixing ring is fixedly connected to the outer surface of the connecting post. The outer surface of the fixing ring is slidably connected to both the sliding groove and the first pipe body. A second connector is fixedly connected to one end of the second pipe body near the first pipe body, and several elastic plates are fixedly connected to the outer surface of the second connector. The outer surface of each elastic plate engages with a corresponding slot.

[0007] Furthermore, a slot is provided on the outer surface of the first connector, and a gasket is inserted into the inner wall of the slot.

[0008] Furthermore, a connector is fixedly connected to the outer surface of the first tube, and an insertion hole is provided on the outer surface of the connector.

[0009] Furthermore, a connecting plate is provided above the connector, and a T-shaped plate is fixedly connected to the inner wall of the connecting plate. The outer surface of the T-shaped plate is slidably connected to the connector.

[0010] Furthermore, the outer surface of the connecting plate is fixedly connected to two fixing posts, and the inner wall of each fixing post is slidably connected to a plug rod, and the outer surface of each plug rod is inserted into a corresponding plug hole.

[0011] Furthermore, the outer surface of each of the inserts is slidably connected to the connecting plate, and a pull block is fixedly connected to the end of each insert away from the connecting plate.

[0012] Furthermore, each of the insert rods has a spring fitted onto its outer surface. The ends of two springs that are close to each other are fixedly connected to the corresponding insert rods, and the other ends are fixedly connected to the corresponding fixing posts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model comprises a first pipe body, a second pipe body, a rotating wheel, a first connector, a second connector, an elastic clamping plate, a connecting post, a fixing ring, a slot, a sliding groove, and a threaded post. By connecting the first connector and the second connector, the elastic clamping plate engages along the corresponding slot, allowing for quick installation of the first and second connectors. Then, by rotating the rotating wheel, the threaded post rotates around the first pipe body. This rotation causes the connecting post to slide horizontally along the sliding groove. Finally, the fixing ring squeezes the elastic clamping plate, causing it to open. This achieves the effect of quickly assembling and disassembling the exhaust pipe by adjusting the engagement / disengagement of the elastic clamping plate and the slot.

[0015] 2. This utility model incorporates components such as a pull block, connecting plate, T-shaped plate, connector, insertion hole, insertion rod, and spring. By horizontally inserting the connecting plate carrying the T-shaped plate along the connector, pulling the pull block causes the corresponding insertion rod to enter the connector. The spring is compressed until the insertion rod and the corresponding insertion hole are aligned on the same central axis. At this point, releasing the pull block allows the spring to push the corresponding insertion rod into the corresponding insertion hole under its rebound force. This achieves the effect of quickly installing the connector by inserting the insertion rod into the corresponding insertion hole. Attached Figure Description

Detailed Implementation

[0023] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0024] Please see Figure 1 - Figure 5 This utility model discloses a connection structure for a vehicle exhaust pipe, comprising a first pipe body 1 and a second pipe body 2. The first pipe body 1 is the tail end of the vehicle exhaust pipe, and the second pipe body 2 is the output end of the exhaust pipe. A rotating wheel 4 is rotatably connected to the outer surface of the first pipe body 1. By rotating the rotating wheel 4, the rotating wheel 4 will rotate on the first pipe body 1. A threaded post 5 is fixedly connected to the outer surface of the rotating wheel 4. The rotation of the rotating wheel 4 will drive the threaded post 5 to rotate on the first pipe body 1. A first connector 9 is fixedly connected to one end of the first pipe body 1. Several slots 10 are formed on the outer surface of the first connector 9. A sliding groove 6 is formed on the outer surface of the first pipe body 1. A connecting post 7 is threadedly connected to the outer surface of the threaded post 5. A fixing ring 8 is fixedly connected to the outer surface of the connecting post 7. Specifically, the rotation of the threaded post 5 will drive the connecting post 7 to move horizontally along the threaded post 5. At this time, the horizontal movement of the connecting post 7 will push the fixing ring 8 to move horizontally. Four sliding grooves 6 are provided and evenly distributed on the outer side of the first pipe body 1.

[0025] In a preferred embodiment, the outer surface of the fixing ring 8 is slidably connected to both the sliding groove 6 and the first tube 1. The connection between the fixing ring 8 and the sliding groove 6 allows the fixing ring 8 to slide horizontally along the sliding groove 6. At this time, the setting of the sliding groove 6 can prevent the fixing ring 8 from rotating in the first tube 1. The second tube 2 is fixedly connected to a second connector 3 at one end near the first tube 1. A plurality of elastic locking plates 11 are fixedly connected to the outer surface of the second connector 3. The outer surface of each elastic locking plate 11 is engaged with the corresponding locking groove 10. Specifically, by connecting the second connector 3 with the first connector 9, the elastic locking plate 11 will be inserted along the corresponding locking groove 10. At this time, the elastic locking plate 11 will first open until the first connector 9 and the second connector 3 come into contact, and then the elastic locking plate 11 will be engaged in the corresponding locking groove 10.

[0026] In this embodiment, a slot is provided on the outer surface of the first connector 9, and a gasket 20 is inserted into the inner wall of the slot. Specifically, by installing the gasket 20 in the slot of the first connector 9, the airtightness between the first connector 9 and the second connector 3 can be increased.

[0027] Looking back Figure 2 , Figure 4 A connector 12 is fixedly connected to the outer surface of the first tube 1. A T-shaped groove is provided on the upper surface of the connector 12, and an insertion hole 13 is provided on the outer surface of the connector 12. Specifically, the insertion hole 13 is provided on the left and right sides of the connector 12.

[0028] In this embodiment, a connecting plate 14 is provided above the connector 12. A T-shaped plate 15 is fixedly connected to the inner wall of the connecting plate 14. The outer surface of the T-shaped plate 15 is slidably connected to the connector 12. Specifically, the T-shaped plate 15 is inserted along the connecting plate 14. During this process, the T-shaped plate 15 will be inserted along the T-slot. The connecting plate 14 can be installed on the vehicle body by using bolts.

[0029] like Figure 2 , Figure 3 , Figure 4 Two fixing posts 16 are fixedly connected to the outer surface of the connecting plate 14. Each fixing post 16 has a sliding rod 17 connected to its inner wall. The outer surface of each rod 17 is inserted into the corresponding insertion hole 13. Specifically, the fixing posts 16 are set on the left and right sides of the connecting plate 14. Each rod 17 can slide horizontally along the corresponding fixing post 16. The connecting plate 14 can be quickly fixed by inserting the rod 17 into the corresponding insertion hole 13.

[0030] In this embodiment, the outer surface of each insertion rod 17 is slidably connected to the connecting plate 14, and a pull block 18 is fixedly connected to the end of each insertion rod 17 away from the connecting plate 14. Specifically, by pulling the pull block 18, the pull block 18 will slide horizontally along the corresponding fixed post 16.

[0031] In this embodiment, each insertion rod 17 is fitted with a spring 19 on its outer surface. The ends of the two springs 19 that are close to each other are fixedly connected to the corresponding insertion rod 17, and the other ends are fixedly connected to the corresponding fixing post 16. Specifically, when the pull block 18 is pulled, the insertion rod 17 will slide horizontally along the corresponding fixing post 16. At this time, the spring 19 will be compressed until the insertion rod 17 and the corresponding insertion hole 13 are on the same central axis. At this time, the pull block 18 is released, and the spring 19 will push the corresponding insertion rod 17 into the insertion hole 13 under the action of its rebound force.

[0032] The implementation principle is as follows: First, the first tube 1 with the first connector 9 is pressed against the second connector 3. During this process, the elastic plate 11 is inserted along the corresponding slot 10. Then, the elastic plate 11 opens until the first connector 9 and the second connector 3 come into contact. At this time, the elastic plate 11 is locked in the corresponding slot 10. The connecting plate 14 is installed on the vehicle body using bolts. Then, the connector 12 is inserted along the T-shaped plate 15. During this process, by pulling the pull block 18, the pull block 18 will drive the corresponding insertion rod 17 to slide horizontally along the corresponding fixed post 16. Spring 19 is compressed until the socket 13 and the corresponding plug 17 are on the same central axis. Then, the pull block 18 is released, and spring 19 pushes the corresponding plug 17 into the corresponding socket 13 under its rebound force. This allows for the quick installation of the connector 12 with the first tube 1. By rotating the rotating wheel 4, the rotating wheel 4 will drive the threaded column 5 to rotate on the first tube 1. At this time, the connecting column 7 will drive the fixing ring 8 to slide horizontally along the slide groove 6. At this time, the fixing ring 8 will squeeze the elastic plate 11 to open it, and the first tube 1 can be quickly disassembled.

[0033] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
