[0023] The technical scheme of the utility model will be further described in detail below in combination with specific embodiments, and the parts not described and disclosed in the following embodiments of the utility model should be understood as the prior art known or known by those skilled in the art, such as the structure and operation mode of the relay protection body, the connection mode of the electric wire end and the plug, etc.

[0024] Embodiment 1

[0025] As shown in Figure 1 , 2 The embodiment discloses a relay protection device, which comprises a box 1 and a relay protection body 2 arranged in the box 1, and a plurality of wire holes 3 are formed in the side wall of the box 1, a plurality of electric wires 4 are connected to the relay protection body 2, the number of the electric wires 4 is the same as that of the wire holes 3, the electric wires 4 of the relay protection body 2 pass through the wire holes 3 one by one and extend out of the box 1, and it can be understood that the number of the wire holes 3 can also be more than that of the electric wires 4 on the relay protection body; the end of the electric wire 4 located outside the box 1 passes through the clamping plate 9 and is connected with the plug 10, the fixed column 8 is arranged on the side wall of the box 1, and the fixing ring capable of suspending the clamping plate 9 on the fixed column 8 is arranged on the clamping plate 9.

[0026] Different from the prior art, the mounting plate 7 is slidably arranged on the outer wall of the box 1, the mounting plate 7 is in the shape of a long strip, a plurality of rotating drums 6 with circular cross sections are arranged on the plate surface of the mounting plate 7 at intervals, the plurality of rotating drums 6 are arranged in a straight line, and a wire passing channel for the electric wire 4 is formed between the adjacent rotating drums 6. The width of the wire passing channel is slightly larger than the diameter of the electric wire 4, and the electric wire 4 extending out of the box 1 from the wire hole 3 is arranged in the wire passing channel, and each electric wire 4 is arranged in a wire passing channel, so that the electric wire 4 can be arranged and the cross winding caused by too many electric wires 4 can be avoided.

[0027] In order to avoid the electric wire 4 in the wire-through channel from falling off in use, the drum 6 is provided with a plurality of coaxial stop rings 11 at the end away from the mounting plate 7, and the minimum distance between adjacent stop rings 11 is less than the diameter of the electric wire 4. The stop rings 11 are made of flexible materials such as rubber, plastic and the like, and can be deformed by external force and reset after the external force is removed. The stop rings 11 in the embodiment are made of rubber. In use, the electric wire 4 is placed between adjacent stop rings 11, and the electric wire 4 is pressed to make the stop rings 11 deformed, and the electric wire 4 falls into the wire-through channel. Since the stop plate limits the electric wire 4 in the wire-through channel, the electric wire 4 is not easy to fall off. When a longer electric wire 4 is needed for wiring, the electric wire 4 can be pulled outwardly to make the stop plate deformed, so that the electric wire 4 is pulled out of the wire-through channel.

[0028] As shown in Figure 3 the middle part of the drum wall of the drum 6 is concave to the center line of the drum 6, forming a wire-through channel with a circular cross section, which facilitates the sliding of the electric wire 4 in the wire-through channel and reduces the friction between the drum wall of the drum 6 and the electric wire 4. It should be noted that in the embodiment, the distance between the upper ends of adjacent drum walls is less than the distance in the middle part. The distance between the upper ends can be the same as or slightly less than the diameter of the electric wire 4. The electric wire 4 is wrapped with a flexible insulating layer, so that the electric wire 4 can be placed in the wire-through channel by slightly deforming the insulating layer under stress. Alternatively, the distance between the upper ends can be greater than the diameter of the electric wire 4, and the electric wire 4 is limited by the stop rings 11 on the upper part of the drum 6.

[0029] The drum 6 includes a fixed shaft 602 and a drum body 601 rotatably arranged on the fixed shaft 602. The drum body 601 can be a hollow structure or a solid structure. The end of the fixed shaft 602 away from the stop rings 11 protrudes from the drum body 601, and the fixed shaft 602 is arranged on the mounting plate 7. Specifically, the fixed shaft 602 is fixedly connected to the mounting plate 7, and can be connected by welding, screwing or interference fit. In the embodiment, the mounting plate 7 is provided with a mounting hole, the inner wall of the mounting hole is provided with an internal thread, and the side wall of the fixed shaft 602 protruding from the drum body 601 is provided with an external thread matched with the internal thread of the mounting hole, so that the fixed shaft 602 is screwed to the mounting plate 7.

[0030] The outer wall of the box body 1 is provided with a sliding groove 5, and the mounting plate 7 is slidingly arranged in the sliding groove 5. The mounting plate 7 is a strip-shaped plate, and the sliding groove 5 is a strip-shaped groove. The length of the sliding groove 5 is greater than the length of the strip-shaped plate. In order to avoid the mounting plate 7 from falling off from the sliding groove 5, the two groove walls in the length direction of the sliding groove 5 are each provided with a concave limiting groove, and the limiting groove is consistent with the length direction of the sliding groove 5. The strip-shaped plate is provided with a limiting protrusion for being inserted into the limiting groove. The limiting protrusion is consistent with the length direction of the strip-shaped plate. Through the cooperation of the limiting groove and the limiting protrusion, the sliding block can slide back and forth in the sliding groove 5, and the sliding block is prevented from falling off from the sliding groove 5.

[0031] There is at least one mounting plate 7. In order to accommodate the arrangement of longer wires 4, there can also be multiple mounting plates 7, with multiple mounting plates 7 distributed in parallel. In this embodiment, there are two mounting plates 7.

[0032] As another arrangement (not shown) in which the mounting plate 7 is slidably mounted on the side wall of the box body 1, a guide bar is fixed to the outer wall of the box body 1, and a slideway is formed on the bottom surface of the mounting plate 7 for the guide bar to engage with, and the length of the slideway is shorter than the length of the guide bar. The position of the mounting plate 7 on the outer wall of the box body 1 is changed by sliding the mounting plate 7 along the guide bar.

[0033] Example 2

[0034] The overall structure of this embodiment is the same as that of embodiment 1, except that Figure 4 As shown, in this embodiment, the rotating drum 6 is cylindrical, the outer diameter of the retaining ring 11 on the rotating drum 6 is larger than the diameter of the rotating drum 6, and the distance between adjacent rotating drums 6 is larger than the diameter of the wire 4.

[0035] In the present invention, the wire passing channel is formed by adjacent rotating drums 6. On the one hand, when the wire 4 passes through the wire passing channel, the rotating drum 6 will rotate as the wire 4 moves, which facilitates the passage of the wire 4 and reduces the wear of the wire 4 caused by the movement of the wire 4 in the wire passing channel. On the other hand, the side wall of the rotating drum 6 is arc-shaped, so the outlet of the wire passing channel formed is an outward-expanding outlet, which also reduces the wear of the wire 4 during the turning process to a certain extent.

[0036] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
