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 implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and 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" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1, reference Figures 1 to 4 , which is the first embodiment of the present invention, provides a distribution network cross arm insulating protective cover, which includes an external component 100, including a first insulating protective cover 101 and a second insulating protective cover 102 provided at one end of the first insulating protective 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 disposed at one end of the first insulating protective cover 101 and the second insulating protective cover 102 and a limiting plate 301a disposed at one end of the first transverse plate 301; and,

[0031] The extrusion assembly 400 includes a second transverse plate 401 disposed inside 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, so that they have 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, so as to completely wrap the cross arm 101a and then protect it from damage.

[0037] Example 2, reference Figures 1 to 4 , which is the second embodiment of the present invention, and this embodiment 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 first insulating protective cover 101 and the second insulating protective cover 102 are provided with a second mounting block 204 at the other end.

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

[0039] Usage process: After the limiting assembly 300 is embedded in the limiting groove 201 through the limiting groove 201 set 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 connected through the limiting assembly 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 crossarm insulating protective cover, which includes a limiting component 300 and also includes a sliding plate 301b arranged at one end of the first cross plate 301, a limiting block 301b-1 is arranged at one end of the sliding plate 301b, and an elastic member 302 is arranged at one end of the sliding plate 301b, 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 pressing 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 the sliding plate 301b is driven to slide backward through the first horizontal plate 301. At this time, the sliding The plate 301b will squeeze the elastic member 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 member 302 will release its elastic force, so that the elastic member 302 drives the sliding plate 301b and the first transverse plate 301 to reset, and the first transverse 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.
