A knob is fixedly installed at the upper end of each of the two screws, and a clamp is rotatably installed at the lower end of each of the two screws.
[0007] Furthermore, the two sleeve structures and the inner pipe are movably sleeved together, and flanges are fixedly installed at both ends of the inner pipe.
[0008] Furthermore, rubber arc plates are embedded at both the front and rear ends of the sleeve, and the insert is made of rubber.
[0009] Furthermore, a protrusion is fixedly provided on the lower part of the inner wall of the rear side of the sleeve plate.
[0010] Furthermore, the two sleeve structures are arranged rotationally symmetrically at the center of the inner pipe.
[0011] Furthermore, the thermal insulation filler is made of expanded perlite.
[0012] This utility model has the following beneficial effects:
[0013] This utility model proposes an insulated sleeve structure, which consists of two rotationally symmetrical sleeve structures fitted around an inner pipe. The two sleeve structures are joined together using connecting buckles and connecting nuts. Inserts and slots are respectively provided on the underside of the extension plates on the front and rear sides of the sleeve plate. The inserts are inserted into the slots, and the rubber arc sheets on both sides of the sleeve plate fit against the flanges on both sides of the inner pipe, thus forming a closed space between the two sleeve plates and the inner pipe. An inner cavity is formed inside the sleeve plate, and insulation filling is provided inside the cavity, giving the sleeve structure a good insulation effect. The two sleeve structures covering the inner pipe facilitate removal from the inner pipe, allowing for convenient inspection of the pipe's interior and timely detection and handling of potential problems. Two threaded sleeves are embedded at the upper end of the sleeve plate, and threaded rods are threaded inside the threaded sleeves. Rotating the threaded rods moves the clamping plates, allowing the clamping plates to hold the inner pipe, thus achieving stable support for the inner pipe. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Reference Figure 1 , Figure 5 One embodiment provided by this utility model:
[0023] An insulated sleeve structure includes two sleeve structures 1 and an inner pipe 2, which are movably fitted together. Flanges 3 are fixedly installed at both ends of the inner pipe 2. The two sleeve structures 1 are arranged symmetrically around the center of the inner pipe 2.
[0024] Specifically, two sleeve structures 1 are set to protect the inner pipe 2. Flanges 3 are set on both sides of the inner pipe 2 to facilitate the connection of multiple sections of the inner pipe 2. The two sleeve structures 1 are set in a rotational symmetrical manner, so that the two sleeve structures 1 can be spliced together.
[0025] Reference Figure 2 , Figure 3 , Figure 4 The sleeve structure 1 includes a sleeve plate 101, an inner cavity 102 is opened inside the sleeve plate 101, and a heat insulation filler 103 is fixedly installed inside the inner cavity 102. Extension plates 104 are fixedly installed on both sides of the sleeve plate 101. A slot 106 is opened on the lower side of the front extension plate 104, and an insert 105 is fixedly installed on the lower side of the rear extension plate 104. Three connecting buckles 107 are fixedly installed at the front end of the front extension plate 104, and three connecting buckles 108 are fixedly installed at the rear end of the rear extension plate 104. Threaded sleeves 109 are embedded in the front and rear sides of the upper side of the sleeve plate 101. A screw 110 is threaded inside the two threaded sleeves 109. A knob 111 is fixedly installed at the upper end of the two screws 110, and a clamping plate 112 is rotatably installed at the lower end of the two screws 110.
[0026] Rubber arc plates 114 are embedded at both the front and rear ends of the sleeve plate 101, the insert strip 105 is made of rubber, a protrusion 113 is fixedly installed on the lower part of the inner wall of the rear side of the sleeve plate 101, and the thermal insulation filler 103 is made of expanded perlite.
[0027] Specifically, an inner cavity 102 is created inside the sleeve 101, and an insulation filler 103 is installed in the inner cavity 102. The insulation filler 103 is made of expanded perlite, which is lightweight, has good thermal insulation performance, and low water absorption, thus providing insulation. Extension plates 104 are installed on both sides of the sleeve 101. When installing the two sleeve structures 1, insert strips 105 are inserted into slots 106. The insert strips 105 are made of rubber, which provides a good seal. Rubber arc plates 114 are embedded on both sides of the sleeve 101 and the flanges 3 on both sides of the inner pipe 2 fit tightly together, thus ensuring a tight seal between the two sleeve structures 1 and the inner pipe 2. A sealed cavity structure is formed, which, together with the insulation filling 103, gives the sleeve structure 1 excellent insulation performance. The two sleeve structures 1 are connected by setting the connecting buckle 107 and the connecting buckle nut 108. By setting the clamp 112, the position of the clamp 112 can be adjusted by rotating the screw 110, so that the clamp 112 can stably support the inner pipe 2. By setting the protrusion 113 on one side of the inner wall of the sleeve 101, the two protrusions 113 in the two sleeves 101 can fit and limit the connection, so that the two sleeves 101 can be quickly aligned when connected, thus facilitating quick installation.
[0028] Working principle: In use, the two sleeve structures 1 surround the inner pipe 2 and are connected by connecting buckles 107 and connecting nuts 108. Insert strip 105 is inserted into slot 106. The insert strip 105 is made of rubber to provide a good seal. Rubber arc plates 114 are embedded on both sides of the sleeve plate 101 and fit tightly with the flanges 3 on both sides of the inner pipe 2, thus forming a sealed cavity structure between the two sleeve structures 1 and the inner pipe 2. Combined with the insulation filling 103, the sleeve structure 1 has excellent thermal insulation performance. Since there are two sleeve structures 1, the structure can be easily disassembled, which facilitates the inspection of the inside of the pipe and timely detection and handling of potential problems.
