DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0025] As shown in Figures 1 to 4 The utility model provides a line protection device for electrical engineering, U shape protection box 1 and apron 2, four mounting blocks 3 are fixedly connected to the vertical direction below of U shape protection box 1, and the upper surface of four mounting blocks 3 is all set up with the bolt hole that passes up and down, and the corner of the lower surface of U shape protection box 1 is all fixedly connected with pad foot 4, and the inner wall of U shape protection box 1 is provided with clamping assembly 5, and the outer surface of apron 2 is overlapped with the inner wall of U shape protection box 1.

[0026] Through the setting of mounting block 3, the installation connection of protection device and other objects can be conveniently realized. In addition, the setting of clamping assembly 5 can limit multiple electric wires at the same time, and the combination of U shape protection box 1 and apron 2 constitutes a box body, effectively protecting the limited electric wire.

[0027] As shown in Figures 1 to 4 The vertical direction left and right sides of U shape protection box 1 are all set up with the positioning mouth 11 that passes front and back, and the lower surface of the inner wall of U shape protection box 1 is set up with several pass-through openings 12 that pass up and down, and the inner wall opposite surface below of U shape protection box 1 is all set up with the clamping block slot 13, and the lower surface of apron 2 is all fixedly connected with the elastic plate 21 of front and back sides, and the outer surface of elastic plate 21 is all fixedly connected with two semicircle blocking blocks 23 of one side near U shape protection box 1, and the outer surface of elastic plate 21 is fixedly connected with semicircle clamping block 24 below of one side near U shape protection box 1, and the upper surface of apron 2 is set up with several pass-through openings 22 that pass up and down, and the outer surface of front and back elastic plate 21 is overlapped with the inner wall of U shape protection box 1, and the outer surface of front and back semicircle blocking block 23 is corresponding with the interior of positioning mouth 11 one to one, and the outer surface of semicircle blocking block 23 is overlapped with the interior of positioning mouth 11, and the outer surface of front and back semicircle clamping block 24 is corresponding with the interior of clamping block slot 13 one to one, and the outer surface of semicircle clamping block 24 is overlapped with the interior of clamping block slot 13.

[0028] When disassembling, the worker moves the cover plate 2 upward, driving the elastic plate 21 to move upward. In this process, due to the action of the semicircular blocking block 23, the semicircular blocking block 23 is in contact with and tightly abuts against the inner wall of the positioning port 11, causing the elastic plate 21 to bend and deform. At the same time, the semicircular clamping block 24 interacts with the clamping block groove 13, causing the elastic plate 21 to be further pressed and deformed. When the elastic plate 21 moves upward again, the semicircular clamping block 24 is separated from the clamping block groove 13, and the semicircular blocking block 23 is also separated from the positioning port 11, thereby completing the disassembly operation of the cover plate 2. In the process of the cover plate 2 rising, the clamping plate two 54 is also driven, facilitating the worker to check the line. Conversely, when assembling, the worker presses the cover plate 2 downward, driving the elastic plate 21, the semicircular blocking block 23 and the semicircular clamping block 24 to move downward. Since the semicircular clamping block 24 and the semicircular blocking block 23 are in contact with the inner wall of the U-shaped protective box 1 respectively, the elastic plate 21 is pressed and deformed. When the elastic plate 21 is completely inserted into the U-shaped protective box 1, its self-elastic effect causes it to reset. At this time, the semicircular clamping block 24 is clamped into the clamping block groove 13, and the semicircular blocking block 23 enters the positioning port 11, thereby realizing the positioning and clamping of the elastic plate 21 and the cover plate 2.

[0029] As shown in Figures 1 to 4 The clamping assembly 5 comprises clamping plate one 51 and clamping plate two 54. The material of the clamping plate one 51 and the clamping plate two 54 is rubber. The lower surface of the clamping plate one 51 is fixedly connected with the upper surface of the inner wall of the U-shaped protective box 1. The upper surface of the clamping plate two 54 is fixedly connected with the lower surface of the cover plate 2. The upper surface of the clamping plate one 51 is provided with a plurality of placement grooves one 52. The plurality of placement grooves one 52 are communicated left and right. The front and rear sides of the upper surface of the clamping plate one 51 are fixedly connected with a plurality of rubber insertion blocks 53. The outer surfaces of the plurality of rubber insertion blocks 53 are provided with patterns. The lower surface of the clamping plate two 54 is provided with a plurality of placement grooves two 55. The plurality of placement grooves two 55 are communicated left and right. The upper surface of the clamping plate two 54 is provided with a plurality of heat dissipation grooves one 56 which are communicated up and down. The heat dissipation grooves one 56 correspond to the strip-shaped ports 22 one by one. The lower surface of the clamping plate one 51 is provided with a plurality of heat dissipation grooves two 511 which correspond to the through ports 12 one by one. The lower surface of the clamping plate two 54 is provided with a plurality of insertion ports 541. The inner surfaces of the plurality of insertion ports 541 are respectively inserted and tightly connected with the outer surfaces of the rubber insertion blocks 53.

[0030] When the cover plate 2 is pressed and the clamping plate two 54 is moved, the clamping plate two 54 is inserted into the socket 541 to be tightly pressed. At this time, the rubber plug 53 is in a retracted state and tightly fits the inner wall of the socket 541. The pattern design in the rubber plug 53 effectively increases the friction, so that the clamping plate two 54 and the cover plate 2 are more stable during assembly. In addition, the placement groove two 55 and the placement groove one 52 are arranged to help define the position of the wire. At this time, the clamping plate two 54 and the clamping plate one 51 on the upper and lower sides are not completely closed, and the placement groove two 55 and the placement groove one 52 are in contact with the outer surface of the wire, thereby limiting the wire. The design of the heat dissipation groove two 511, the heat dissipation groove one 56, the through hole 12 and the strip-shaped hole 22 has the characteristics of limiting the wire and ventilating and dissipating heat.

[0031] The working principle of the line protection device for electrical engineering will be described in detail below.

[0032] When disassembling, the worker moves the cover plate 2 upward to move the elastic plate 21 upward. In this process, due to the action of the semicircular blocking block 23, the semicircular blocking block 23 is in contact with and tightly pressed against the inner wall of the positioning hole 11, causing the elastic plate 21 to bend and deform. At the same time, the semicircular clamping block 24 interacts with the clamping block groove 13, so that the elastic plate 21 is further pressed and deformed. When the elastic plate 21 is moved upward again, the semicircular clamping block 24 is separated from the clamping block groove 13, and the semicircular blocking block 23 is also separated from the positioning hole 11, thereby completing the disassembly operation of the cover plate 2. When the cover plate 2 is pressed and the clamping plate two 54 is moved, the clamping plate two 54 is inserted into the socket 541 to be tightly pressed. At this time, the rubber plug 53 is in a retracted state and tightly fits the inner wall of the socket 541. The pattern design in the rubber plug 53 effectively increases the friction, so that the clamping plate two 54 and the cover plate 2 are more stable during assembly. In addition, the placement groove two 55 and the placement groove one 52 are arranged to help define the position of the wire.

[0033] The above has made a detailed description of the utility model, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, without departing from the modification or improvement of the spirit of the utility model, it is within the protection scope of the utility model.
