[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] See Figs. 1-3This embodiment discloses a heat insulation cover for heat insulation of an exhaust pipe. Specifically, it is an exhaust pipe heat insulation cover, including an elastic element 101, a heat insulation cover body, and a connecting mechanism 102 for mounting at both ends of the heat insulation cover body. The left and right ends of the elastic element 101 are fixedly connected with connecting rings 103, and the heat insulation cover body is used to be mounted on the exhaust pipe body 118.

[0035] The connecting mechanism 102 includes a connecting plate 104 and a first connecting hook 105 for cooperating with the connecting ring 103. The connecting plate 104 is used to be installed on the heat insulation cover body. The first connecting hook 105 is slidably installed on the connecting plate 104. A first baffle 106 is fixedly connected to the connecting plate 104. After the first connecting hook 105 contacts the first baffle 106, it forms an installation area for limiting the connection ring 103.

[0036] When the connecting ring 103 engages with the first connecting hook 105, the left and right ends of the heat insulation cover body can be connected.

[0037] In this embodiment, the heat insulation cover body is used to be installed on the exhaust pipe body 118. When heat insulation of the exhaust pipe body 118 is required, the heat insulation cover body is first wrapped around the exhaust pipe body 118, and the connecting mechanisms 102 installed at both ends of the heat insulation cover body are aligned. After the connecting rings 103 fixedly connected to the left and right ends of the elastic member 101 are respectively sleeved onto the first connecting hooks 105 fixedly connected to both ends of the heat insulation cover body, the first connecting hooks 105 move towards the first baffle 106 under the force provided by the elastic member 101. When the first connecting hooks 105 contact the first baffle 106, the first baffle 106 can engage the first connecting hooks 105. The installation area formed between hook 105 and the first baffle 106 is sealed, so that the connecting ring 103 will not come out of the installation area under the influence of external forces, ensuring that the heat insulation cover body can be stably installed on the exhaust pipe body 118 after the cooperation of the connector and the connecting mechanism 102, thus providing heat insulation for the exhaust pipe body 118. Compared with the prior art of connecting the heat insulation cover body by sequentially turning multiple screws through the fixed guide holes, the cooperation of the connector and the connecting mechanism 102 in this embodiment can effectively improve the installation efficiency and avoid wasting time and manpower. In this embodiment, the elastic element 101 is a conventional tension spring structure in the prior art.

[0038] In some embodiments, the connecting plate 104 is provided with a groove 107, and the bottom end of the first connecting hook 105 is provided with a slider 108 for cooperating with the groove 107. The first connecting hook 105 is slidably mounted on the connecting plate 104 via the slider 108. By providing the groove 107, the slider 108 and the first connecting hook 105 can be limited, preventing the first connecting hook 105 from separating from the connecting plate 104 during sliding.

[0039] In some embodiments, the first baffle 106 is provided with a groove 109 for limiting the first connecting hook 105. After the first connecting hook 105 moves to the point of contact with the groove 109 under the force provided by the elastic member 101, the first baffle 106 can close the installation area formed between the first connecting hook 105 and the first baffle 106; by providing the groove 109, the contact area between the first connecting hook 105 and the first baffle 106 can be increased, further improving the sealing effect of the first baffle 106 on the first connecting hook 105.

[0040] In some embodiments, the first connecting hook 105 is provided with a limiting groove 110 for limiting the connecting ring 103. After the connecting ring 103 is fitted onto the first connecting hook 105, the connecting ring 103 moves into the limiting groove 110 under the force of the elastic member 101. By providing the limiting groove 110, the connecting ring 103 can be limited, thereby improving the stability of the connection between the elastic member 101 and the connecting mechanism 102.

[0041] In some embodiments, a second connecting hook 111 is slidably mounted on the connecting plate 104, and a second baffle 112 for closing the open end of the second connecting hook 111 is fixedly connected to the connecting plate 104. In this embodiment, there are two sliding grooves 107, which are arranged sequentially along the direction of the connecting plate 104; the first connecting hook 105 and the second connecting hook 111 are slidably mounted in the two sliding grooves 107 respectively; when the heat insulation cover body is installed on pipes of different diameters, the connecting ring 103 can cooperate with the first connecting hook 105 or the second connecting hook 111 as needed, so that the heat insulation cover body can cover and insulate pipes of different diameters.

[0042] In some embodiments, a buffer block 113 is installed in the slide groove 107. The buffer block 113 is made of rubber material. By setting the buffer block 113, the impact force generated when the first connecting hook 105 or the second connecting hook 111 contacts the slide groove 107 under the force of the elastic member 101 can be absorbed, thereby avoiding collision between the first connecting hook 105 or the second connecting hook 111 and the slide groove 107.

[0043] In some embodiments, the heat shield body includes a steel wire mesh layer 114 and a heat insulation layer 115 arranged sequentially from the inside to the outside. The steel wire mesh layer 114 is used to contact the exhaust pipe body 118. The steel wire mesh layer 114 can enhance the strength of the heat shield body while isolating the direct heat radiation of the high-temperature exhaust to the inner side of the heat shield body, reducing the risk of heat damage and extending the service life of the heat shield body and the exhaust system. The heat insulation layer 115 can isolate the high temperature on the surface of the exhaust pipe, prevent heat from being transferred to surrounding components, and protect key components such as the fuel tank, body parts, and suspension components from high temperature.

[0044] In some embodiments, a high-temperature resistant fabric layer 116 is provided outside the heat insulation layer 115. The high-temperature resistant fabric layer 116 is made of a heat insulation material with good wear resistance and hydrophobicity, which can resist the erosion of external environmental factors such as rainwater, snow and road debris, and extend the service life of the heat insulation cover body.

[0045] In some embodiments, the high-temperature fabric layer is provided with vent holes 117. By providing the vent holes 117, some of the heat inside the heat insulation cover body can be discharged, preventing the internal temperature of the heat insulation cover body from becoming too high and protecting the heat insulation cover body and other related components from high-temperature damage.

[0046] In some embodiments, a sealing plug is detachably installed on the exhaust port 117. The sealing plug is threaded into the exhaust port 117. When it is necessary to maintain a high temperature inside the exhaust system to improve the conversion efficiency of the catalytic converter, the sealing plug can be used to seal the exhaust port 117. When it is necessary to discharge some of the heat inside the heat shield body, the sealing plug can be rotated to remove the exhaust port 117.

[0047] Preferred embodiments of the present invention have been described, but those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
