DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0028] Example 1, with reference to Figures 1 to 4 , which is the first embodiment of the present invention, provides a distribution network cross arm insulation protection cover, which includes an external component 100, including a first insulation protection cover 101 and a second insulation protection cover 102 provided at one end of the first insulation protection cover 101; and,

[0029] The bearing assembly 200 includes a limiting groove 201 formed in the first insulating protective cover 101 and the second insulating protective cover 102; and

[0030] The limiting assembly 300 includes a first transverse plate 301 provided at one end of the first insulating protective cover 101 and the second insulating protective cover 102 and a limiting plate 301a provided at one end of the first transverse plate 301; and

[0031] The extrusion assembly 400 includes a second transverse plate 401 disposed within the first insulating protective cover 101 and the second insulating protective cover 102 .

[0032] The external component 100 further includes a cross arm 101 a disposed inside the first insulating protective cover 101 and the second insulating protective cover 102 .

[0033] The length of the cross arm 101a is 1500 mm, and the length of the first insulating protective cover 101 and the second insulating protective cover 102 is 250 mm.

[0034] The first insulating protective cover 101 and the second insulating protective cover 102 are made of silicone rubber.

[0035] The first insulating protective cover 101 and the second insulating protective cover 102 are made of silicone rubber, thereby providing them with better insulation properties.

[0036] Usage process: It is composed of multiple first insulating protective covers 101 and second insulating protective covers 102, which can be disassembled and assembled conveniently and quickly. After the multiple first insulating protective covers 101 and second insulating protective covers 102 are assembled, one end of the cross arm 101a is inserted into the first insulating protective cover 101 and the second insulating protective cover 102, thereby completely wrapping the cross arm 101a and protecting it from damage.

[0037] Example 2, reference Figures 1 to 4 , which is the second embodiment of the present invention, provides a distribution network cross-arm insulating protective cover, which includes a bearing assembly 200 and also includes a sliding groove 201a opened in the first insulating protective cover 101 and the second insulating protective cover 102, the first insulating protective cover 101 and the second insulating protective cover 102 are provided with a bearing groove 202 on the inner side, the first insulating protective cover 101 and the second insulating protective cover 102 are provided with a first mounting block 203 at one end, and the other end of the first insulating protective cover 101 and the second insulating protective cover 102 is provided with a second mounting block 204.

[0038] The first mounting block 203 and the second mounting block 204 are trapezoidal in shape.

[0039] Usage process: After the limiting groove 201 is set in the first insulating protective cover 101 and the second insulating protective cover 102, the limiting component 300 is embedded in the limiting groove 201, and the first insulating protective cover 101 and the second insulating protective cover 102 are connected through the limiting component 300 to be fixedly installed, thereby realizing quick assembly and increasing its practicality.

[0040] Example 3, reference Figures 1 to 4 , which is the third embodiment of the present invention, and this embodiment provides a distribution network cross-arm insulation protective cover, which includes a limiting component 300 and also includes a sliding plate 301b arranged at one end of the first horizontal plate 301, one end of the sliding plate 301b is provided with a limiting block 301b-1, one end of the sliding plate 301b is provided with an elastic member 302, and the elastic member 302 is an elastic sheet.

[0041] One end of the limiting plate 301a is configured as an inclined surface.

[0042] The extrusion assembly 400 also includes an extrusion block 401a arranged at one end of the second horizontal plate 401, a fixed plate 402 is provided at one end of the second horizontal plate 401, a convex plate 402a is provided at one end of the fixed plate 402, a friction groove 402a-1 is opened at one end of the convex plate 402a, and the friction groove 402a-1 is laid on the convex plate 402a.

[0043] One end of the extrusion block 401a is configured as an inclined surface.

[0044] Among them, when it is necessary to remove the first insulating protective cover 101 and the second insulating protective cover 102, the friction force is increased by setting up multiple friction grooves 402a-1, and the friction grooves 402a-1 drive the convex plate 402a and the fixed plate 402 to move to the left, the fixed plate 402 drives the second horizontal plate 401 to move to the left, and the second horizontal plate 401 drives the extrusion block 401a to move to the left. At this time, through the contact between the extrusion block 401a and the inclined surface of the limiting plate 301a, the extrusion block 401a drives the limiting plate 301a to move backward, and the limiting plate 301a cancels the connection with the limiting groove 201, thereby releasing the connection between the first insulating protective cover 101 and the second insulating protective cover 102, and then facilitating the removal of the first insulating protective cover 101 and the second insulating protective cover 102.

[0045] Usage process: When the first insulating protective cover 101 and the second insulating protective cover 102 are assembled, the first insulating protective cover 101 and the second insulating protective cover 102 are aligned and merged together. When the first insulating protective cover 101 and the second insulating protective cover 102 are merged together, the limiting groove 201 will squeeze the inclined surface of the limiting plate 301a, so that the limiting plate 301a drives the first horizontal plate 301 to slide backward, and then drives the sliding plate 301b to slide backward through the first horizontal plate 301. At this time, the sliding The plate 301b will squeeze the elastic part 302. When the limiting plate 301a is squeezed and slides backward, the limiting plate 301a will be embedded in the limiting groove 201. At this time, the squeezed elastic part 302 will release its elastic force, so that the elastic part 302 drives the sliding plate 301b and the first horizontal plate 301 to reset, and the first horizontal plate 301 drives the limiting plate 301a to reset. At this time, the limiting plate 301a will be stuck on the limiting groove 201, thereby realizing the assembly of the first insulating protective cover 101 and the second insulating protective cover 102.
