Description

Technical Field

[0001] This utility model belongs to the technical field of automotive pipeline heat insulation components, specifically relating to a heat insulation sleeve at a clamp connection. Background Technology

[0002] During automobile development, components such as the engine, electrical equipment, and exhaust system generate heat during energy conversion or operation, which is unavoidable. At the same time, some components of the car need to be protected from heat sources, so heat dissipation pipes must be insulated.

[0003] Currently, pipeline insulation protection is divided into two parts: non-joint pipe locations and pipe joint and bend locations. Non-joint pipe locations have regular shapes and can be directly fitted with tubular insulation sleeves; however, pipe joints and bend locations, due to the need for clamps, have irregular shapes and cannot be directly fitted with commonly used insulation sleeves, making insulation more difficult. Furthermore, the joint connections involve sealing and are critical protection areas, making insulation protection even more urgent.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a heat-insulating sleeve for clamp connections to solve the technical problem that it is inconvenient to wrap the pipe joint position in the prior art.

[0006] To achieve the above objectives, the heat-insulating sleeve at the clamp connection of this utility model provides the following technical solution:

[0007] A heat-insulating sleeve for a clamp connection includes:

[0008] A linear wrapping section, the linear wrapping section being used for detachably wrapping a straight-shaped pipe;

[0009] An arc-shaped wrapping section is integrally formed at one end of a linear wrapping section and is used to detachably wrap the turning part of the pipe.

[0010] Both the linear and arc-shaped wrapping parts have heat-insulating buffer layers on their inner sides. The radial dimension of the inner cavity of the arc-shaped and / or linear wrapping parts is larger than the outer dimension of the clamp, so as to fully wrap the clamp. One side of the arc-shaped and linear wrapping parts has a through opening, and the arc-shaped and linear wrapping parts are detachably connected to the pipe through the opening.

[0011] As a further optimized technical solution, a stitching structure is provided on the side of the arc-shaped wrapping part opposite to the opening, so that the arc-shaped wrapping part fits the bend of the pipe.

[0012] As a further optimized technical solution, two connecting plates are provided on both sides of the opening, and the two connecting plates are used to control the opening or closing of the opening.

[0013] As a further optimized technical solution, the length of each connecting plate in the linear wrapping portion is aligned with the end of the linear wrapping portion that is away from the arc-shaped wrapping portion.

[0014] As a further optimized technical solution, the height of each connecting plate is not lower than the end of the arc-shaped wrapping portion that is away from the linear wrapping portion.

[0015] As a further optimized technical solution, the two connecting plates are arranged symmetrically.

[0016] As a further optimized technical solution, the connecting plate is located on one side of the arc-shaped wrapping part facing the center of the pipe bend.

[0017] As a further optimized technical solution, the connecting plate is provided with a movable connector for detachable docking of two connecting plates.

[0018] As a further optimized technical solution, the movable connector is a snap fastener.

[0019] As a further optimized technical solution, the male and female buckles are provided at intervals along the length extension direction of the connecting plate.

[0020] Beneficial effects: Through the combined design of linear and arc-shaped wrapping parts, combined with the heat insulation buffer layer arranged on the inner side, it can accurately adapt to the joints and bends of the pipes. At the same time, the inner cavity size of the linear wrapping part and / or the arc-shaped wrapping part is larger than that of the clamp, thereby achieving all-round wrapping of the pipe joints and bends, fundamentally solving the technical problem of heat insulation in this position in the existing technology.

[0021] Furthermore, the fit between the opening and the connecting plate and the movable connector, especially the multiple spaced snap fasteners, makes the heat insulation sleeve easy to install and remove, while also ensuring the stability of the installation, guaranteeing the overall heat insulation performance, effectively ensuring the safe and stable operation of key automotive components in high-temperature environments, extending the service life of automotive parts, and reducing maintenance costs.

[0028] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art are within the protection scope of this utility model.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0031] The shapes and sizes of the components in the attached drawings do not reflect the actual proportions of the product; they are only intended to illustrate the content of this utility model.

[0032] This invention provides a heat-insulating sleeve for clamp connections. The heat-insulating sleeve includes a linear wrapping part for wrapping a straight pipe and an integrally formed arc-shaped wrapping part. Both have a heat-insulating buffer layer on their inner sides, and the inner cavity size is larger than the clamp to achieve wrapping. An opening is provided on one side of both the arc-shaped and linear wrapping parts, allowing for a detachable connection with the pipe. This invention solves the problem of poor heat insulation at pipe joints and bends caused by clamps, and has the advantages of convenient installation, tight fit, and stable heat insulation performance. It can effectively ensure the stable operation of key automotive components in high-temperature environments and reduce maintenance costs.

[0033] Example 1

[0034] like Figure 1-4 As shown, the heat insulation sleeve at the clamp connection includes an integrally formed linear wrapping part 1 and an arc-shaped wrapping part 2. The linear wrapping part 1 is used to detachably wrap the straight pipe 3; the arc-shaped wrapping part 2 is located at one end of the linear wrapping part 1 and is used to detachably wrap the bend of the pipe 3.

[0035] Both the linear wrapping part 1 and the arc-shaped wrapping part 2 have heat-insulating buffer layers on their inner sides and heat-insulating layers on their outer sides to ensure the heat insulation of the pipeline. The radial dimension of the inner cavity of the arc-shaped wrapping part 2 and / or the linear wrapping part 1 is larger than the outer dimension of the clamp 4, so as to fully wrap the clamp 4. In this embodiment, the clamp 4 is only set on the straight part of the pipe 3 joint. Therefore, only the radial dimension of the inner cavity of the linear wrapping part 1 is larger than the outer dimension of the clamp 4, which facilitates the full wrapping of the irregularly shaped clamp 4 inside the linear wrapping part 1. Although the clamp 4 is not set at the bend of the pipe 3, the significance of the arc-shaped wrapping part 2 is firstly to prevent the overall heat insulation sleeve from moving axially along the pipe 3. Secondly, the arc-shaped wrapping part 2 can extend to the heat insulation sleeve at the non-joint position after the bend of the pipe 3, thereby ensuring more comprehensive heat insulation protection for the pipe 3.

[0036] To facilitate installation and disassembly, an opening 5 is provided on one side of the arc-shaped wrapping part 2 and the linear wrapping part 1, which extends through the inner and outer sides. The arc-shaped wrapping part 2 and the linear wrapping part 1 are detachably connected to the pipe 3 through the opening 5.

[0037] Furthermore, a stitching structure 8 is provided on the side of the arc-shaped wrapping part 2 opposite to the opening 5, so that the arc-shaped wrapping part 2 fits the bend of the pipe 3. In this embodiment, the arc-shaped wrapping part 2 and the linear wrapping part 1 are made of aluminum foil fiberglass cloth. The stitching structure 8 at the position of the arc-shaped wrapping part 2 can make the arc-shaped wrapping part 2 form an arc-shaped structure that matches the shape of the bend of the pipe 3. Moreover, by adjusting the setting of the stitching structure 8, the radial dimension of the arc-shaped wrapping part 2 can be further adjusted, so that the arc-shaped wrapping part 2 can more tightly wrap the bend of the pipe 3.

[0038] Furthermore, two connecting plates 6 extend symmetrically from both sides of the opening 5. The connecting plates 6 are located on one side of the arc-shaped wrapping part 2 turning towards the center of the pipe 3. The extension length of each connecting plate 6 on the linear wrapping part 1 is aligned with the end of the linear wrapping part 1 away from the arc-shaped wrapping part 2, and the height is not lower than the end of the arc-shaped wrapping part 2 away from the linear wrapping part 1. The connecting plate 6 is provided with a movable connector 7. In this embodiment, the movable connector 7 specifically adopts a snap-fit ​​structure. Multiple snap-fits are spaced apart along the length extension direction of the connecting plate 6. This design not only enables the detachable docking of the two connecting plates 6, but also allows for flexible adjustment of the number and position of multiple snap-fits according to the actual size of the pipe 3, thereby precisely controlling the opening and closing degree of the opening 5, ensuring that the heat insulation sleeve is tightly fitted to the pipe 3, and preventing heat leakage.

[0039] When installing the thermal insulation sleeve, first open the opening 5, then place the linear wrapping part 1 onto the straight section of the pipe 3, and place the curved wrapping part 2 onto the turning point of the pipe 3. Then, align the connecting plates 6 on both sides of the opening 5, and fasten the male and female fasteners to complete the installation of the thermal insulation sleeve.

[0040] In certain special scenarios, such as when a car operates in an extremely high-temperature environment for an extended period, the temperature of pipe 3 rises rapidly. In this case, the heat insulation buffer layer on the inner wall of the heat insulation sleeve can effectively block heat transfer, preventing heat from being conducted to clamp 4 and other automotive components. When the car is traveling on bumpy roads, the high-strength material of the connecting plate 6 and the tight connection of the male and female fasteners ensure that the heat insulation sleeve is securely wrapped around pipe 3, preventing it from loosening or falling off due to vibration, and continuously providing excellent heat insulation protection.

[0041] Example 2

[0042] The difference between this embodiment and embodiment 1 lies in the setting of the inner radial dimensions of the arc-shaped wrapping part 2 and the linear wrapping part 1. In this embodiment, the clamp 4 is set on both the straight part and the bent part of the pipe 3. At this time, the inner radial dimensions of the arc-shaped wrapping part 2 and the linear wrapping part 1 need to be larger than the outer dimensions of the clamp 4 to facilitate the complete wrapping of the clamp 4.

[0043] Example 3

[0044] The difference between this embodiment and embodiment 1 lies in the setting of the inner radial dimensions of the arc-shaped wrapping part 2 and the linear wrapping part 1. In this embodiment, the clamp 4 is only set in the bent part of the pipe 3 joint. At this time, only the inner radial dimension of the arc-shaped wrapping part 2 is greater than the outer dimension of the clamp 4, so that the irregularly shaped clamp 4 can be fully wrapped inside the arc-shaped wrapping part 2.

[0045] Example 4

[0046] The difference between this embodiment and embodiment 1 lies in the setting of the movable connector 7. In this embodiment, the movable connector 7 is a movable clip or Velcro.

[0047] In summary, the heat insulation sleeve at the clamp connection provided by this utility model effectively solves the heat insulation problem of automotive pipe joints and turning positions. It has a reasonable structural design, is easy to use, and has good practicality and promotional value.

[0048] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
