Description

Technical Field

[0001] The present application relates to the technical field of automobile accessories, and in particular to a heat insulating bushing for automobile engines. Background Art

[0002] The engine thermal insulation bushing is an important component in the automobile engine. It can effectively insulate, prevent the engine from overheating, and protect the normal operation of the engine. The thermal insulation bushing is usually composed of one or more layers of insulating materials, which can effectively isolate the temperature difference between the engine and the outside world in a high temperature environment. The thermal insulation bushing is mainly divided into two parts: internal insulation and external insulation. Internal insulation: The engine will generate a lot of heat when working. The internal insulation bushing is located on the outside of each cooling component of the engine (such as coolant pipelines, intake pipes, etc.), which plays a role in insulation, reduces conduction heat, and avoids excessive loss.

[0003] Usually, the inner heat insulation bushing is installed after the engine is installed on the vehicle. Therefore, the inner heat insulation bushing is generally a flat heat insulation bushing, and then it is wrapped around the coolant pipeline and the intake pipe. After the staff wraps the heat insulation bushing around the pipeline, they need to tighten the heat insulation bushing by hand to prevent it from loosening and becoming fluffy, which will cause the pipeline to not fit, and then use a cable tie to tie the heat insulation bushing to the pipeline. This makes the installation of the heat insulation bushing inconvenient. Utility Model Content

[0022] The following is combined with Figure 1-3 This application is described in further detail.

[0023] The present application embodiment discloses a heat insulating bushing for an automobile engine. Figure 1 The thermal insulation bushing for automobile engine comprises an outer thermal insulation layer 1, an inner thermal insulation layer 2 and an elastic tie assembly 3. The outer thermal insulation layer 1 is located outside the inner thermal insulation layer 2, and the outer thermal insulation layer 1 and the inner thermal insulation layer 2 are sewn together. The elastic tie assembly 3 is arranged on one side of the outer wall of the outer thermal insulation layer 1, and a button 11 is arranged on the side of the outer wall of the outer thermal insulation layer 1 away from the elastic tie assembly 3 so that the thermal insulation bushing can be fixed on the pipeline after wrapping the pipeline.

[0024] Reference Figure 1 and Figure 2 A long strip of magnetic sheet 12 is fixedly installed between the outer insulation layer 1 and the inner insulation layer 2. The magnetic sheet 12 is located between the outer insulation layer 1 and the inner insulation layer 2 on the side close to the button 11. When wrapping the pipeline, one side of the insulation sleeve can be first adsorbed on the pipeline through the magnetic sheet 12, and the staff does not need to hold it with hands to limit it all the time.

[0025] The outer wall of the outer heat insulation layer 1 on the side where the button 11 is provided is sewn with a Velcro 13, and the Velcro 13 and the button 11 are arranged at intervals, and the button 11 is located between the Velcro 13 and the elastic lace assembly 3. The inner wall of the inner heat insulation layer 2 away from the Velcro 13 is sewn with a Velcro mother patch 21 that is attached to the Velcro 13. When the heat insulation bushing is installed, the side of the heat insulation bushing on which the magnetic suction sheet 12 is provided is first adsorbed on the pipeline, and then the pipeline is wrapped. After wrapping, the Velcro 13 and the Velcro mother patch 21 are adhered together, and then the heat insulation bushing is pre-positioned on the pipeline.

[0026] Reference Figure 1 and Figure 2, wherein an arc-shaped bending spring piece 22 is arranged between the outer insulation layer 1 and the inner insulation layer 2, and the middle part of the outer insulation layer 1 and the inner insulation layer 2 along the direction from the button 11 to the elastic strap assembly 3 is bent into an arc under the action of the arc-shaped bending spring piece 22, so that when the insulation bushing is installed on the pipeline, the arc-shaped part of the insulation bushing can be directly buckled on the pipeline. Two insertion pockets 23 for inserting and positioning the ends of the arc-shaped bending spring piece 22 are sewn on the inner insulation layer 2, and the two insertion pocket buckles are respectively located at the two ends of the arc-shaped bending spring piece 22, so as to limit the arc-shaped bending spring piece 22 on the inner insulation layer 2. Multiple arc-shaped bending spring pieces 22 are arranged at intervals along the axial direction after the insulation bushing wraps the pipeline.

[0027] There are multiple sets of elastic tie assemblies 3, and the multiple sets of elastic tie assemblies 3 are arranged at intervals along the axial direction after the heat insulating sleeve wraps the pipeline. Correspondingly, the number of buttons 11 is consistent with the number of elastic tie assemblies 3 and corresponds one to one. The following is an example of the combination of a set of elastic tie assemblies 3 and buttons 11.

[0028] Reference Figure 1 and Figure 3 The elastic strap assembly 3 includes a connecting cloth strip 31, a tension spring 32, a first connecting ring 33 and a second connecting ring 34. The first connecting ring 33 and the second connecting ring 34 are respectively welded to the two ends of the tension spring 32. A canvas rivet 35 is provided on the outer insulation layer 1, and the first connecting ring 33 is fixed on the canvas rivet 35. One side of the connecting cloth strip 31 is fixedly connected to the second connecting ring 34. A button hole 311 for the button 11 to enter is provided on the connecting cloth strip 31. There are multiple button holes 311, and the multiple button holes 311 are arranged at intervals along the length of the connecting cloth strip 31, so that the thermal insulation bushing is suitable for pipelines of different diameters. The setting of the tension spring 32 enables the connecting cloth strip 31 to have a pulling wrapping force after being tied to the button 11, so that the fixation of the thermal insulation bushing is more stable.

[0029] The implementation principle of a heat-insulating bushing for automobile engines in the embodiment of the present application is as follows: when the heat-insulating bushing is wrapped on the pipeline, first, the middle part of the heat-insulating bushing is bent into an arc-shaped part through the arc-shaped bending spring sheet 22 and buckled on the pipeline, and then the side of the heat-insulating bushing with the magnetic suction sheet 12 is adsorbed on the pipeline through the magnetic suction sheet 12; then the other end of the heat-insulating bushing is wrapped around the pipeline; after wrapping the pipeline, the Velcro 13 and the Velcro 21 of the heat-insulating bushing are pasted together to achieve pre-fixation. Finally, pull the connecting cloth strip 31 to drive the tension spring 32 to open, so that the button 11 can be buckled into the corresponding buttonhole 311 on the connecting cloth strip 31, thereby making the installation process more convenient.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
