[0018] 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.
[0019] Please see Figure 1-4 This utility model provides a technical solution:
[0020] A detachable pipe insulation sleeve includes a composite insulation sleeve body 1. An outer cover 2 is sewn to the top and bottom of the front of the composite insulation sleeve body 1. A left plastic clip 3 is glued to the left side of the joint of the composite insulation sleeve body 1, and a right plastic clip 4 is glued to the right side of the joint of the composite insulation sleeve body 1. Limiting arc plates 5 are fixedly connected to the front and rear ends of the opposite side of the right plastic clip 4 and the left plastic clip 3. A first sealing gasket 6 and a female buckle 8 are respectively provided at the front, rear and middle positions of the side of the left plastic clip 3 near the right plastic clip 4. A second sealing gasket 7 and a female buckle 9 are respectively provided at the front, rear and middle positions of the side of the right plastic clip 4 near the left plastic clip 3.
[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the inner surface of the composite insulation jacket body 1 is provided with protrusions 15, which are semi-circular in shape. The semi-circular protrusions 15 increase the anti-slip force of the inner surface of the composite insulation jacket body 1. The inner surface of the outer cover 2 is sewn with round-pile hook and loop fasteners 10. The surface of the composite insulation jacket body 1 facing the round-pile hook and loop fasteners 10 is sewn with barbed hook and loop fasteners 11. The barbed hook and loop fasteners 11 and the round-pile hook and loop fasteners 10 are bonded together. The bonding of the hook and loop fasteners allows the entire pipe insulation jacket to be easily disassembled. The outer left side of the composite insulation jacket body 1 is sewn with an outer protrusion 13. The outer protrusion 13 is snapped with a binding ring 14. A tightening strap 12 passes through the inner side of the binding ring 14. The tightening strap 12 is sewn to the outer cover 2. After the tightening strap 12 passes through the binding ring 14 and is knotted and tightened, the installation of the composite insulation jacket body 1 can be fixed a second time.
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the male buckle 8 is positioned in the middle between the two first sealing gaskets 6. The outer end of the male buckle 8 and the inner end of the female buckle 9 are shaped to match each other. The connection between the left plastic clip plate 3 and the two limiting arc plates 5 forms a "U" shaped structure. The limiting arc plates 5 and the composite insulation sleeve body 1 are bonded together. The arrangement positions of the first sealing gasket 6 and the second sealing gasket 7 are arranged opposite to each other. The mating arrangement between the male buckle 8 and the female buckle 9 allows for auxiliary pre-positioning of the composite insulation sleeve body 1 before the Velcro is bonded.
[0023] Workflow: Before using the insulation accessory of this utility model, it is necessary to ensure that the "U"-shaped structure composed of the left plastic clamping plate 3 and the two limiting arc plates 5 is fixed to the left side of the joint of the composite insulation sleeve body 1, and also to ensure that the "U"-shaped structure composed of the right plastic clamping ring and the two limiting arc plates 5 is fixed to the right side of the joint of the composite insulation sleeve body 1. When the thermal equipment is started and running, and the detachable pipe insulation sleeve needs to be installed on the outside of the pipe, first pull the tightening strap 12 out of the restraining clamping ring 14, then open the outer cover 2 outward to unfold the joint of the composite insulation sleeve body 1, align it with the outside of the pipe, and put the composite insulation sleeve body 1 on the outside of the pipe, so that the multiple protrusions 15 are tightly attached to the surface of the pipe. Then, the composite insulation sleeve body 1 is glued and fixed. Previously, with the auxiliary connection of two sets of limiting arc plates 5, the male buckle 8 set on the left plastic card plate 3 and the female buckle 9 set on the right plastic card plate 4 were snapped together. The first sealing gasket 6 and the second sealing gasket 7 were fitted together, so that the joint of the composite insulation sleeve body 1 could be assisted in alignment by snapping. Then, the stitching position of the barbed hook and loop fastener 11 was aligned and the outer cover was covered, so that the barbed hook and loop fastener 11 and the round hook and loop fastener 10 were glued together, and the composite insulation sleeve body 1 was fixed once. Then, under the connection of the outer protrusion 13, the binding strap 12 connecting the outer cover cloth 2 was passed through the inside of the binding ring 14 and tied to fix it, thus fixing the composite insulation sleeve body 1 a second time, so that it could be stably installed on the outside of the pipe to carry out the corresponding insulation work.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
