Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermal insulation covers, in particular to a wedge-type installation structure for thermal insulation covers. Background Art
[0002] The thermal insulation cover is an important component commonly found on automobile exhaust pipes. Its main function is to provide thermal insulation. During the driving process of the car, the high-temperature exhaust gas emitted by the engine is discharged through the exhaust pipe. The exhaust pipe will be affected by the high temperature, which will reduce the fuel combustion efficiency on the one hand, and cause thermal damage to the surrounding parts on the other hand. In order to effectively avoid this situation, the thermal insulation cover is designed to be installed on the exhaust pipe, which can effectively reduce the heat loss, keep the temperature of the exhaust pipe stable, and prevent the heat from affecting the surrounding parts of the vehicle.
[0003] At present, there are certain problems with the design of the heat shield on some automobile exhaust pipes. The fixing method is to open a mounting hole on the cover body and then fix the heat shield to the exhaust pipe with screws. However, this design is not conducive to the installation, removal and replacement of the heat shield by the staff, and the operation is relatively cumbersome. In addition, with the vibration generated when the car is driving, the tightness of the screws may be affected, causing the screws to loosen, which in turn affects the normal use of the heat shield. This fixing method is not only inconvenient for maintenance operations, but also has safety hazards. It may cause the heat shield to fall off or be damaged, reducing the efficiency and reliability of the automobile exhaust system.
[0004] Therefore, it is necessary to provide a wedge-type installation structure for a thermal insulation cover to solve the above technical problems. Utility Model Content

[0029] A thermal insulation cover wedge-type installation structure, comprising:
[0030] A first cover body 1, a second cover body 2 is arranged at the bottom of the first cover body 1, wedge blocks 7 are fixedly installed on both sides of the bottom of the first cover body 1, wedge grooves 15 are opened on both sides of the top of the second cover body 2, and the wedge grooves 15 are adapted to the wedge blocks 7, and a plurality of rectangular holes 14 are opened on both sides of the outer surface of the second cover body 2, and the rectangular holes 14 are connected to the inside of the wedge grooves 15;
[0031] A limiting groove 10 is provided at the bottom of the inner wall of the rectangular hole 14, a limiting rod 12 is fixedly installed inside the limiting groove 10, a limiting block 9 is sleeved on the outer wall of the limiting rod 12, and the limiting block 9 is slidably connected to the limiting groove 10, and a second spring 11 is sleeved on one side of the limiting block 9 on the outer wall of the limiting rod 12;
[0032] A rectangular plug rod 13 is fixedly installed on the top of the limit block 9, and the rectangular plug rod 13 is slidably connected to the rectangular hole 14. A positioning groove 8 corresponding to the position and number of the rectangular plug rod 13 is opened on one side of the wedge block 7, and the positioning groove 8 is clamped with the rectangular plug rod 13.
[0033] A plurality of telescopic rods 6 are fixedly mounted on the inner surfaces of the first cover body 1 and the second cover body 2, a clamping plate 4 is fixedly mounted on the telescopic end of the telescopic rod 6, a first spring 5 is sleeved on the outer wall of the telescopic rod 6, and shock absorbers 16 are fixedly mounted on both sides of the telescopic rod 6 on the inner surfaces of the first cover body 1 and the second cover body 2, and one end of the shock absorber 16 is fixedly connected to the clamping plate 4 at the corresponding position.
[0034] In one embodiment, an operating member 3 is fixedly mounted on one end of the rectangular rod 13 close to the outside of the second cover body 2, and the operating member 3 is L-shaped, which is convenient for operating the positions of multiple rectangular rods 13 at one time and facilitating the disassembly of the heat insulation cover.
[0035] In one preferred embodiment, one end of the rectangular rod 13 away from the operating member 3 is inclined, and the rectangular rod 13 is matched with the positioning groove 8, so as to facilitate the quick docking installation between the first cover body 1 and the second cover body 2.
[0036] In one embodiment, a sliding hole matched with the limiting rod 12 is opened on one side of the limiting block 9, and the limiting block 9 is slidably connected with the limiting rod 12 through the sliding hole opened on one side.
[0037] In one of the preferred embodiments, the materials of the first cover body 1, the second cover body 2 and the splint 4 are all made of aluminum alloy, and the inner surfaces of the first cover body 1 and the second cover body 2 are provided with a thermal insulation coating. The design of aluminum alloy material and thermal insulation coating can make the thermal insulation cover have good strength, high temperature resistance, lightweight characteristics and excellent thermal insulation performance, thereby ensuring the normal operation of the automobile exhaust system and the safe use of components.
[0038] The working principle of the utility model is as follows: the parts not involved in the device are the same as the prior art or can be implemented by the prior art. When installing the thermal insulation cover, first fit the second cover body 2 to the lower side of the exhaust duct, then fit the first cover body 1 to the upper side of the exhaust duct, and make the bottom of the first cover body 1 fit with the top of the second cover body 2. At this time, the wedge block 7 at the bottom of the first cover body 1 will be directly inserted into the inside of the wedge-shaped groove 15 at the top of the second cover body 2. During the insertion process, the wedge block 7 will contact the inclined end of the rectangular plug rod 13, so that the rectangular plug rod 13 slides into the inside of the rectangular hole 14. During the movement, the rectangular plug rod 13 will drive the limit block 9 to slide on the outer wall of the limit rod 12 and squeeze the second spring 11. As the wedge block 7 is fully inserted into the inside of the wedge groove 15, the rectangular plug rod 13 will be clamped into the inside of the side positioning groove 8 of the wedge block 7 under the elastic action of the second spring 11, so that the wedge block 7 is firmly clamped. The first and second covers 1 and 2 are wrapped and installed on the outer wall of the exhaust pipe in the wedge-shaped groove 15. When disassembling them later, a rod-shaped tool is inserted into the operating member 3 on one side, and then the operating member 3 on one side is pulled as a whole, so that the operating member 3 drives the rectangular plug rod 13 to disengage from the inside of the side positioning groove 8 of the wedge block 7. At this time, the first cover body 1 can be directly pulled out from the top of the second cover body 2 to complete the disassembly of the thermal insulation cover. The detachable structure between the first cover body 1 and the second cover body 2 is connected by the clamping method of the wedge block 7 and the wedge-shaped groove 15 to ensure the fit and stability of the connection between the first cover body 1 and the second cover body 2. In addition, the rectangular plug rod 13 is elastically clamped with the positioning groove 8 to further ensure the firmness of the first cover body 1 and the second cover body 2 after the connection. Compared with the traditional screw fixing, the operation method of the detachable structure is simpler to disassemble and assemble, which improves the convenience of people's operation.
[0039] After the first cover body 1 and the second cover body 2 are sleeved on the outer wall of the exhaust pipe, the clamping plate 4 located inside the first cover body 1 and the second cover body 2 will be tightly clamped on the outer wall of the exhaust pipe under the elastic action of the first spring 5, so that the exhaust pipe is centrally installed inside the heat insulation cover, which improves the heat insulation effect of the heat insulation cover on the exhaust pipe. In addition, with the shock absorption effect of the shock absorber 16, the overall shaking between the exhaust pipe and the heat insulation cover is reduced, and the stability during use after installation is improved. The function of the shock absorber reduces the vibration of the entire exhaust system during driving, reduces the impact on the connection structure of the heat insulation cover, and prolongs the service life of the heat insulation cover.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
