一种可拆卸的防护套管

Abstract

本申请提供了一种防护套管，该防护套管包括内层管和外层管；内层管沿着内管长度方向设有第一开口，第一开口的边缘处设有相互配合的卡扣结构；外层管沿着外管长度方向设有第二开口，并以第二开口与第一开口边缘对齐且全覆盖的方式粘结于内层管外层，在内层管处于保护待防护体的情况下，内层管包裹于待防护体上且卡扣结构处于闭合状态，在内层管处于从待防护体中剥离的情况下，内层管分离于待防护体且卡扣结构处于分开状态，内层管和外层管采用不同防护材质制成。可见，应用本申请实施例提供的防护套管既能提高防护套管套设裸导线的便利性，又能提高裸导线的安全性，降低危险度。

Claims

1. A detachable protective sleeve, characterized in that, The protective sleeve includes: The inner tube has a first opening along its length, and the edge of the first opening has a snap-fit ​​structure that engages with each other. The outer tube has a second opening along its length and is bonded to the outer layer of the inner tube in a manner that aligns the second opening with the edge of the first opening and fully covers it. When the inner tube is protecting the object to be protected, the inner tube wraps around the object and the snap-fit ​​structure is in a closed state. When the inner tube is being peeled off from the object to be protected, the inner tube separates from the object and the snap-fit ​​structure is in a separated state. The inner tube and the outer tube are made of different protective materials.

2. The protective sleeve of claim 1, wherein, The buckle structure is a flexible body, comprising a buckle and a sleeve. The buckle has a protrusion, and the sleeve has an insertion groove for engaging with the buckle. The end of the buckle away from the protrusion is located at one edge of the first opening, and the end of the sleeve away from the insertion groove is located at the other edge of the first opening. When the inner tube is protecting the object to be protected, the protrusion engages with the insertion groove. When the inner tube is being detached from the object to be protected, the protrusion and the sleeve are separated.

3. The protective sleeve of claim 2, wherein, The protrusion includes a plug and a snap-fit ​​component with end faces increasing in size. The snap-fit ​​component includes a snap-fit ​​connector and a connecting body. The cross-sectional area of ​​the snap-fit ​​connector is greater than or equal to the area of ​​the large end face of the plug and is greater than the cross-sectional area of ​​the connecting body. The large end face of the plug is connected to one end face of the snap-fit ​​connector, and the other end of the snap-fit ​​connector is connected to one end of the connecting body. The other end of the connecting body is connected to the edge of one side of the first opening. The snap-fit ​​sleeve has a plug groove that mates with the plug and the snap-fit ​​component, so that when the plug and the snap-fit ​​component are inserted into the plug groove, the first opening is in a closed state, and when the plug and the snap-fit ​​component are separated from the plug groove, the first opening is in an open state.

4. The protective sleeve of claim 1, wherein, The inner surface of the inner tube is provided with multiple guide grooves along its length.

5. The protective sleeve according to claim 1, characterized in that, The inner tube is an insulating layer.

6. The boot sleeve of claim 5, wherein, The outer tube is made of multiple layers of different materials bonded together.

7. The boot sleeve of claim 6, wherein, The outer tube includes a flame-retardant layer, which is disposed outside the insulating layer.

8. The boot sleeve of claim 7, wherein, The outer tube also includes an anti-icing layer, which is disposed outside the flame-retardant layer.

9. The boot sleeve of claim 8, wherein, The outer tube also includes a self-luminous layer, which is disposed between the flame-retardant layer and the anti-icing layer.

10. The boot sleeve of claim 9, wherein, The surface of the anti-icing coating is provided with a micro-nano composite structure, wherein the micro-protrusion height of the micro-nano composite structure is 5-20μm and the protrusion spacing is 10-50μm.

11. The protective sleeve of any one of claims 1-9, wherein, The bending radius of the protective sleeve is less than or equal to the sleeve diameter.
