Description

Technical Field

[0001] The utility model relates to the technical field of branch pipes, in particular to a branch pipe thermal insulation sheath. Background Art

[0002] When installing a household or commercial multi-split air conditioner, a branch pipe is required in the online pipeline to divert and collect the refrigerant. The branch pipe distributes the refrigerant in the refrigeration system from one path to two paths, or collects the two refrigerants into one path, so as to form a complete air conditioning piping system. At present, the insulation and anti-condensation of the copper pipe branch pipe in the central air-conditioning installation are very important, so it is usually necessary to install an insulation jacket on the outer wall of the branch pipe.

[0003] The existing new composite branch pipe (publication number: CN208365075U) has at least the following disadvantages: the above scheme ensures the insulation and leakage-proof effect by arranging an external locking device to press and seal the insulation sleeve shell from both ends, but because the insulation sleeve is divided into two, and the bonding surface of the two insulation sleeves is a traditional plane structure, after the two insulation sleeves are bonded, they are greatly affected by shear force or tensile force, etc., which may cause peeling or breaking of the bonding point, and the connection is unreliable, thereby affecting the anti-condensation and anti-drip effect of the insulation sleeve. For this reason, the present utility model is proposed. Utility Model Content

The inner side of the front cover is provided with a first clamping cavity, and the inner side of the rear cover is provided with a second clamping cavity. The first clamping cavity and the second clamping cavity form a circular cavity. A first protrusion and a second protrusion are respectively arranged on one side of the front cover, and a first recessed portion and a second recessed portion are respectively arranged on one side of the rear cover.

[0022] like Figure 1-Figure 4 As shown, the branch pipe insulation cover includes an insulation cover body 1, which is made of glass fiber and has a certain toughness. The insulation cover body 1 is composed of a front cover 101 and a rear cover 102. The inner side of the front cover 101 is provided with a first clamping cavity 2, and the inner side of the rear cover 102 is provided with a second clamping cavity 201. The first clamping cavity 2 and the second clamping cavity 201 form a circular cavity. One side of the front cover 101 is respectively provided with a first protrusion 202 and a second protrusion 203, and one side of the rear cover 102 is respectively provided with a first recessed portion 204 and a second recessed portion 205.

[0023] like Figure 1-Figure 4As shown, in this embodiment, the first protrusion 202 is arranged around the periphery of the first clamping cavity 2, the second protrusion 203 is arranged around the inner periphery of the first clamping cavity 2, the first recessed portion 204 is opened around the periphery of the second clamping cavity 201, and the second recessed portion 205 is opened around the inner periphery of the second clamping cavity 201. The first protrusion 202 and the first recessed portion 204 are inserted, and the second protrusion 203 and the second recessed portion 205 are inserted. By setting the first protrusion 202 and the second protrusion 203, the front sheath 101 and the rear sheath 101 can be connected. 02 are fitted, so that the first protrusion 202 and the second protrusion 203 are respectively inserted into the first recessed portion 204 and the second recessed portion 205, thereby forming a plug-in mechanism at the connection between the front sheath 101 and the rear sheath 102, which effectively increases the shear resistance or tensile force, and at the same time increases the area on the inner side of the front sheath 101 and the rear sheath 102 that can be coated with glue, increases the tightness of the front sheath 101 and the rear sheath 102 when they are adhered, increases the reliability of the insulation cover main body 1, and increases the anti-condensation and anti-drip effects of the insulation cover main body 1.

[0024] like Figure 1-Figure 4 As shown, in this embodiment, three first avoidance grooves 3 are opened on the inner side of the front sleeve 101, and a second avoidance groove 301 is opened on the inner side of the rear sleeve 102. The first avoidance grooves 3 and the second avoidance grooves 301 form a circular cavity. By setting the first avoidance grooves 3 and the second avoidance grooves 301, the welding parts of the branch pipes can be avoided to prevent the bulges of the welding parts of the branch pipes from affecting the tightness of the front sleeve 101 and the rear sleeve 102.

[0025] like Figure 1-Figure 4 As shown, in this embodiment, a limiting protrusion 4 is provided on the inner side of the front sheath 101 near the top surface, and a limiting recess 401 is provided on the inner side of the rear sheath 102 near the top surface. The limiting protrusion 4 and the limiting recess 401 are inserted into each other. By providing the limiting protrusion 4 and the limiting recess 401, the front sheath 101 and the rear sheath 102 can be limited up and down when they are fitted and fixed, thereby preventing the front sheath 101 and the rear sheath 102 from being misaligned up and down.

[0026] like Figure 1-Figure 4 As shown, in this embodiment, the outer walls of the front sheath 101 and the rear sheath 102 are each provided with three snap-in grooves 5, and the positions of the snap-in grooves 5 on the front sheath 101 and the rear sheath 102 correspond to each other and are connected to each other. By providing the snap-in grooves 5, after the front sheath 101 and the rear sheath 102 are adhered together, a clamp can be used to be internally sleeved on the snap-in grooves 5 to achieve better fixation of the front sheath 101 and the rear sheath 102.

[0027] like Figure 1-Figure 4As shown, in this embodiment, the first clamping cavity 2 and the second clamping cavity 201 form a circular cavity, the first clamping cavity 2 occupies three quarters of the area of ​​the circular cavity, and the second clamping cavity 201 occupies one quarter of the area of ​​the circular cavity. By setting the first clamping cavity 2 to occupy three quarters of the area of ​​the circular cavity, the front sleeve 101 can be clamped on the branch pipe after the branch pipe is clamped with the inside of the first clamping cavity 2, so that the rear sleeve 102 does not need to be supported and lifted when it is aligned and adhered to the front sleeve 101, thereby increasing the convenience of installation of the insulation sleeve main body 1.

[0028] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: in use, the front sheath 101 is clamped with the outer wall of the branch pipe so that the branch pipe is sleeved into the interior of the first clamping cavity 2. At this time, glue is applied to the inner side of the front sheath 101 and the first protrusion 202 and the second protrusion 203. Then, glue is applied to the inner layer of the rear sheath 102 and the first recess 204 and the second recess 205. Then, the rear sheath 102 is placed in a position parallel to the front sheath 101. Then, the limiting protrusion 4 is inserted into the interior of the limiting recess 401 first, and then the rear sheath 102 is slowly pressed into the front sheath 101. Then, the first protrusion 202 and the first recess 204 are inserted, and the second protrusion 203 and the second recess 205 are inserted, thereby completing the installation of the insulation cover body 1. The first avoidance groove 3 and the second avoidance groove 301 are provided to avoid the welding part of the branch pipe, so as to prevent the bulge of the welding part of the branch pipe from affecting the tightness of the front sleeve 101 and the rear sleeve 102. By providing the limiting protrusion 4 and the limiting recess 401, the front sleeve 101 and the rear sleeve 102 can be limited up and down when the front sleeve 101 and the rear sleeve 102 are fitted and fixed, so as to prevent the front sleeve 101 and the rear sleeve 102 from being misaligned up and down. By providing the clamping groove 5, after the front sleeve 101 and the rear sleeve 102 are adhered, the clamp and the internal sleeve of the clamping groove 5 can be used to better fix the front sleeve 101 and the rear sleeve 102. In the circular cavity formed by the first clamping cavity 2 and the second clamping cavity 201, the first clamping cavity 2 occupies three quarters of the area of ​​the circular cavity, and the second clamping cavity 201 occupies one quarter of the area of ​​the circular cavity.
