[0002] Exposed wire protection devices for electrical engineering and automation are specialized equipment designed to protect exposed cables or conduits in electrical engineering and automation fields. These devices, through various mechanisms and materials, are designed to prevent damage to cables or conduits from external factors, thereby ensuring the safe and stable operation of electrical systems. They are not only simple in structure and easy to install, but also effectively reduce the risk of cable or conduit damage.

[0003] Chinese patent CN217956366U discloses an exposed wire protection device suitable for electrical and automation applications. The device includes a housing, a fixing device, a protective device, and a bending device. The fixing device includes a fixing ring with sliding holes at both its upper and lower ends. A sliding post is provided on the inner wall of the housing, and the sliding holes are slidably installed with the sliding post. A lead screw is provided on one side of the fixing ring, and the lead screw is rotatably installed with the fixing ring. A threaded hole is provided on the housing, and the threaded hole is threadedly installed with the lead screw. The other end of the lead screw passes through the housing and is fixedly mounted on a rotating disk. The exposed wire can be fixed by placing it between two fixing rings and then rotating the rotating disk to bring the fixing rings closer together.

[0004] The above-mentioned device can fix wires of different inner diameters. However, in practical applications, the existing device has a complicated installation process and poor sealing performance. When rainwater enters the device, it can easily damage the wires. Therefore, there is a need to provide an exposed wire protection device for electrical and automation applications. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Combination Figures 1-4 An exposed wire protection device for electrical and automation applications includes a first wire housing 1 and a second wire housing 2, with a protection mechanism 3 disposed between the first wire housing 1 and the second wire housing 2. The protection mechanism 3 includes two first rotating seats 301 and two second rotating seats 302, which are respectively fixedly installed on both sides of the first wire housing 1 and the second wire housing 2, passing through the first rotating seats 301 and the second rotating seats 302. Two limiting rods 303 are slidably installed, and top seats 304 are fixedly installed at both ends of the two limiting rods 303. Two retaining plates 305 are fixedly installed side by side between the first wire housing 1 and the second wire housing 2.

[0023] See Figure 2Furthermore, it is found that the interiors of the first rotary seat 301 and the second rotary seat 302 are both provided with arc-shaped grooves. The retaining plate 305 is located inside the first wire shell 1 and the second wire shell 2 and is close to both sides. The two ends of the limiting rod 303 are both provided with irregular grooves. Several annular pads are sleeved on the outside of the top seat 304. The irregular grooves and the annular pads are compatiblely matched.

[0024] Specifically, the exposed wire portion is wrapped inside wire shell 1 and wire shell 2, and wire shell 1 and wire shell 2 are secured by a limiting rod 303. In use, the limiting rod 303 is inserted between the first rotating seat 301 and the second rotating seat 302, and top seats 304 are installed at both ends of the limiting rod 303. Because several annular pads are installed on the outside of the top seats 304, the device can be made more stable. When the device needs to be removed, the limiting rod 303 can be pulled out.

[0025] Example 2

[0026] Combination Figures 1-4 The first wire housing 1 and the second wire housing 2 are equipped with a sealing mechanism 4. The sealing mechanism 4 includes a first buffer pad 401 and a second buffer pad 402. Two first retaining bolts 403 are threaded in parallel on the first buffer pad 401 and penetrating the first wire housing 1. Two second retaining bolts 404 are threaded in parallel on the second buffer pad 402 and penetrating the second wire housing 2. A first sealing seat 405 and a second sealing seat 406 are fixedly installed at both ends of the first wire housing 1 and the second wire housing 2. Wire rings 407 are sleeved on the outside of the first sealing seat 405 and the second sealing seat 406.

[0027] See Figure 3 and Figure 4 Furthermore, based on Embodiment 1, it is further found that the first buffer pad 401 and the second buffer pad 402 are both arc-shaped, and circular pads are fixedly installed between the first buffer pad 401 and the second buffer pad 402 and the first fixing bolt 403 and the second fixing bolt 404, respectively. The first sealing seat 405 and the second sealing seat 406 are both trapezoidal in shape, and annular grooves are opened on the outside of the first sealing seat 405 and the second sealing seat 406. The wire ring 407 is adapted to match the annular groove.

[0028] Specifically, when the exposed wire is restricted by the No. 1 wire housing 1 and the No. 2 wire housing 2, the No. 1 buffer pad 401 and the No. 2 buffer pad 402 are attached to the outside of the exposed wire. By adjusting the No. 1 fixing bolt 403 and the No. 2 fixing bolt 404, pressure is applied to the No. 1 buffer pad 401 and the No. 2 buffer pad 402, thereby making the device tightly fit the exposed wire and increasing the sealing performance of the device. At the same time, the No. 1 wire housing 1 and the No. 2 wire housing 2 fix the No. 1 sealing seat 405 and the No. 2 sealing seat 406. Under the action of the wire ring 407, the device and the exposed wire form a sealed space.

[0029] In actual operation, the exposed wire portion is wrapped inside wire shell 1 and wire shell 2, and wire shell 1 and wire shell 2 are secured by limiting rod 303. When in use, the limiting rod 303 is embedded between the first rotating seat 301 and the second rotating seat 302, and top seats 304 are installed at both ends of the limiting rod 303. Because several annular pads are installed on the outside of the top seat 304, the device can be more stable. When the device needs to be removed, the limiting rod 303 can be pulled out.

[0030] When the exposed wire is confined by wire housing 1 and wire housing 2, buffer pad 401 and buffer pad 402 are attached to the outside of the exposed wire. By adjusting the retaining bolt 403 and retaining bolt 404, pressure is applied to the buffer pad 401 and buffer pad 402, thereby making the device tightly fit the exposed wire and increasing the sealing performance of the device. At the same time, wire housing 1 and wire housing 2 fix the sealing seat 405 and sealing seat 406. Under the action of wire ring 407, the device and the exposed wire form a sealed space.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
