Description

Technical Field

[0001] This utility model relates to the field of thermal insulation sleeve technology, and in particular to a detachable thermal insulation sleeve with protective function. Background Technology

[0002] Thermal insulation jackets, also known as thermal insulation blankets or heat insulation covers, are three-layer thermal insulation devices made of fire-resistant materials that are resistant to high and low temperatures. They consist of an inner lining, a middle insulation layer, and an outer protective layer.

[0003] When using protective sleeves, they are often designed to be detachable for easy removal and replacement. However, this also results in multiple movable connections or open structures, leading to insufficient stress and support strength, especially at the joints between insulation sleeves. If the pipe enclosed by the sleeve is bent or damaged, the sleeve itself can easily be damaged, affecting its continued use. Therefore, we propose a detachable insulation sleeve with protective functions. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a detachable insulation sleeve with protective functions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a detachable heat insulation sleeve with protective function, comprising two arc-shaped plates, which are arranged opposite to each other and are movably connected.

[0006] Arc-shaped connecting plates are coaxially installed on the outer walls of both ends of the arc plate, and several slots are arranged at intervals along the outer wall of the connecting plates.

[0007] Each slot is equipped with a screw rod, one end of which is rotatably mounted on the arc-shaped plate, and two nuts are threaded onto each screw rod.

[0008] Preferably, an arc-shaped insulation pad is coaxially installed on the inner wall of the arc-shaped plate. The insulation pad consists of an inner lining layer and a heat insulation layer, wherein the heat insulation layer is fixedly installed close to the arc-shaped plate, and the inner lining layer is fixed on the inner wall of the heat insulation layer.

[0009] Preferably, the inner lining layer is one of fiberglass cloth, silicone rubber coated fiberglass cloth, aluminum foil cloth, and Teflon coated fiberglass cloth;

[0010] The thermal insulation layer is one of the following: glass fiber cotton, ceramic fiber cotton, rock wool, aerogel felt, and rubber-plastic sponge.

[0011] Preferably, an arc-shaped cut surface is provided along the outer edge of the insulation pad.

[0012] Preferably, the two curved plates are hinged on their relatively close sides, and a fixing plate is installed on the other side of the curved plates, with the two fixing plates being fixed together by at least one fixing bolt.

[0013] Preferably, a pressure plate is installed on the side of each screw where the two nuts are relatively close to each other, and the pressure plate is an elastic annular plate.

[0014] Preferably, a connecting seat is installed at one end of the screw, a support plate is installed at the other end of the connecting seat, a connecting shaft is installed on the support plate, and a support seat is rotatably installed at the other end of the connecting shaft. The support seat is fixed to the outer wall of the arc-shaped plate.

[0015] Preferably, a magnetic absorbing sheet is installed on the outer wall of the curved plate, and the connecting seat is a magnetic metal block, with the connecting seat corresponding to the magnetic absorbing sheet.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] 1. This utility model achieves quick disassembly and installation of the insulation sleeve by setting up structures such as arc-shaped plates, connecting plates, slots, screws and nuts. At the same time, the screws and nuts are used to fasten the multiple connecting plates together, which enhances the overall structural strength and stability of the insulation sleeve, effectively prevents the insulation sleeve from being damaged by pipe deformation or external impact, and improves its service life and scope of application.

[0018] 2. This utility model uses a hinged structure and a fixing plate with fixing bolts to realize the opening, closing and locking of two arc-shaped plates, which facilitates installation and disassembly on pipelines; the screw is rotated and stored through a connecting seat, a support plate, a connecting shaft and a support seat, and is positioned with a magnetic chuck, which not only facilitates transportation and storage, but also improves the convenience and efficiency of on-site installation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example

[0027] Reference Figures 1-5 A detachable insulation sleeve with protective function includes two arc-shaped plates 1, which are arranged opposite each other and movably connected. The two arc-shaped plates 1 are hinged on their closest sides, allowing them to rotate relative to each other. This allows the arc-shaped plates 1 to be unfolded and placed on the pipe during use. A fixing plate 3 is installed on the other side of the arc-shaped plates 1, and the two fixing plates 3 are fixed together by at least one fixing bolt 4. After the arc-shaped plates 1 are placed on the pipe and then joined together, the two arc-shaped plates 1 can be fixed together by the fixing bolt 4, so that the arc-shaped plates 1 are firmly fixed on the pipe.

[0028] It should be noted that, as Figure 1 and Figure 4 As shown, an arc-shaped insulation pad 2 is coaxially installed on the inner wall of the arc plate 1. The insulation pad 2 consists of an inner lining layer and a heat insulation layer. The heat insulation layer is fixed close to the arc plate 1, and the inner lining layer is fixed on the inner wall of the heat insulation layer. The inner lining layer directly contacts the surface of the equipment or pipe to be insulated, while the heat insulation layer is the core layer for performing heat insulation performance.

[0029] The inner lining layer is one of fiberglass cloth, silicone rubber coated fiberglass cloth, aluminum foil cloth, or Teflon coated fiberglass cloth; the thermal insulation layer is one of fiberglass wool, ceramic fiber wool, rock wool, aerogel felt, or rubber and plastic sponge.

[0030] Furthermore, an arc-shaped cut surface 14 is provided along the outer edge of the insulation pad 2, that is, the arc-shaped cut surface 14 is provided at the outer edge of the inner lining layer to prevent operators from being scratched by the sharp edges of the insulation pad 2 when they come into contact with it.

[0031] like Figure 1 and Figure 3As shown, arc-shaped connecting plates 5 are coaxially mounted on the outer walls of both ends of the arc-shaped plate 1, and several spaced slots 6 are opened along the outer wall of the connecting plate 5. Each slot 6 contains a screw 7, one end of which is rotatably mounted on the arc-shaped plate 1, and two nuts 8 are threaded onto each screw 7, i.e. Figure 5 As shown, after the two sets of arc-shaped plates 1 are joined together, the slots 6 on the two connecting plates 5 that are relatively close to each other correspond. After the screw 7 is placed in the slot 6, the nuts 8 on it will be arranged on the side of the two connecting plates 5 that are relatively far apart. By tightening the nuts 8 close to the connecting plates 5 and pressing them against the connecting plates 5, the connecting plates 5 can be fastened. Since one end of the screw 7 is connected to the arc-shaped plate 1, it can support and strengthen the connection between the two sets of arc-shaped plates 1, and also strengthen the pipe that is wrapped, thereby increasing the stress strength of the pipe.

[0032] Furthermore, pressure plates are installed on the relatively close sides of the two nuts 8 on each screw 7. The pressure plates are elastic annular plates. As the nuts 8 press against the connecting plate 5, they compress and deform the pressure plates. Through the elasticity of the pressure plates, a reverse force can be provided to the nuts 8, thereby improving the fastening effect of the nuts 8 against the connecting plate 5.

[0033] It should be noted that, as Figure 2 and Figure 3 As shown, a connecting seat 9 is installed at one end of the screw 7, and a support plate 10 is installed at the other end of the connecting seat 9. A connecting shaft 11 is installed on the support plate 10, and a support seat 12 is rotatably installed at the other end of the connecting shaft 11. The support seat 12 is fixed on the outer wall of the arc plate 1, forming a rotation mechanism of the screw 7 on the outer wall of the arc plate 1, allowing the screw 7 to rotate freely on the outer wall of the arc plate 1. That is, when multiple sets of arc plates 1 are coaxially merged, the screw 7 can be rotated to a position that is close to the outer wall of the arc plate 1 to prevent the outward protrusion of the screw 7 from hindering the coaxial merging of multiple sets of arc plates 1. After the arc plates 1 are merged together, the screw 7 can be rotated back to be placed in the slot 6 for fixation, which provides convenience for the installation of the insulation sleeve on the pipeline.

[0034] Furthermore, a magnetic absorbing piece 13 is installed on the outer wall of the arc plate 1, and the connecting seat 9 is a magnetic metal block. The connecting seat 9 corresponds to the magnetic absorbing piece 13, which can attract and fix the screw 7 when it is placed on the outside of the arc plate 1, so as to prevent the screw 7 from swinging around and making it difficult to transport the arc plate 1.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
