[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] Example 1
[0019] Reference Figure 1 、 2, which is the first embodiment of the utility model, provides a high and low voltage distribution cabinet with an incoming line protection structure, including a cabinet body 1, a cabinet door 2 is hinged on one side of the cabinet body 1, and a plurality of supporting legs 3 are fixedly installed on the bottom end of the cabinet body 1. A plurality of threaded holes 4 are opened at the bottom of the cabinet body 1, and a connecting pipe 5 is sleeved in the threaded hole 4 through a threaded structure. A hexagonal cap 7 is fixedly sleeved on one side of the connecting pipe 5, and a plurality of rubber plates 8 are fixedly connected to the inner wall of the connecting pipe 5. A rubber tube 6 is fixedly sleeved in the rubber plate 8. A plurality of annular cavities 61 are hollow in the rubber tube 6, and a plurality of spheres 62 are fixedly sleeved in the annular cavity 61. A tension spring 64 is respectively provided between two adjacent spheres 62.
[0020] The wiring used in the power distribution cabinet passes through the cabinet body 1 from the bottom of the cabinet body 1. When passing through, the wires pass through the rubber tube 6. The rubber tube 6 is made of elastic rubber material. When the wires pass through, the rubber tube 6 can be opened to facilitate the passage of the wires. After the wires pass through, the wires passed through are bundled under the tension of the tension spring 64 in the annular cavity 61. At the same time, the annular cavities 61 are evenly distributed, and the wires are bundled in layers so that the entered wires are bundled and tightly together. After the rubber tube 6 elastically retracts, the wires are wrapped. At the same time, the height of the rubber tube 6 is greater than the height of the connecting tube 5, that is, the two ends of the rubber tube 6 protrude from the connecting tube 5. The rubber tube 6 wraps and protects the wires to prevent the wires from contacting the two ends of the connecting tube 5. After the rubber tube 6 elastically retracts, the rubber plate 8 is pulled to expand synchronously, thereby filling the gap between the rubber tube 6 and the connecting tube 5. At the same time, the rubber plate 8 is an elastic piano-type rubber plate, which can shrink accordingly according to the diameter of the wire to ensure the sealing of the incoming line position.
[0021] Example 2
[0022] Reference Figure 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment. Specifically, the edges of both ends of the connecting pipe 5 are respectively provided with rounded corners 52. The setting of the rounded corners 52 prevents the two ends of the connecting pipe 5 from causing wear to the rubber tube 6.
[0023] Specifically, the middle outer wall of the connecting tube 5 is provided with an external thread 51, which is threadedly matched with the threaded hole 4, making it easy to install the connecting tube 5 in the threaded hole 4. The threaded hole 4 is the wire entry hole in the prior art. The threaded structure connection method facilitates the installation or removal of the connecting tube 5 according to actual needs.
[0024] Specifically, the rubber plate 8 has an annular structure and is a piano-shaped rubber plate. The annular rubber plate 8 fills the gap between the rubber tube 6 and the connecting tube 5. At the same time, the rubber plate 8 is an elastic piano-shaped rubber plate and can shrink accordingly according to the diameter of the wire, thereby ensuring the sealing of the wire entry position.
[0025] Specifically, the rubber tube 6 is made of elastic rubber material, and at least four spheres 62 are evenly distributed around the circumference. The height of the rubber tube 6 is greater than the height of the connecting tube 5. The setting of the spheres 62 facilitates the setting of tension springs 64 between the spheres 62. The tension springs 64 are distributed in an arc shape under the restriction of the annular cavity 61. The setting of multiple tension springs 64 makes the tension distribution of the tension springs 64 more uniform.
[0026] Specifically, grooves 63 are concavely formed at both ends of the sphere 62. The inner walls of the grooves 63 are fixedly connected to the ends of tension springs 64. The tension springs 64 are movably disposed within the annular cavity 61. The annular cavities 61 are evenly distributed along the length of the rubber tube 6. The rubber tube 6 is made of elastic rubber. When the wire passes through, the rubber tube 6 can be opened to facilitate the passage of the wire. After the wire passes through, the tension of the tension springs 64 in the annular cavity 61 bundles the wire. At the same time, the annular cavities 61 are evenly distributed, bundling the wires in layers, so that the incoming wires are bundled tightly together, thereby protecting the incoming wires of the distribution cabinet.
[0027] Example 3
[0028] Reference Figure 1-4 , which is the third embodiment of the present utility model. This embodiment is based on the above two embodiments. When in use, the line used in the power distribution cabinet passes through the cabinet body 1 from the bottom of the cabinet body 1. When passing through, the wire passes through the rubber tube 6. The rubber tube 6 is made of elastic rubber material. When the wire passes through, the rubber tube 6 can be opened to facilitate the passing of the wire. After the wire passes through, the tension of the tension spring 64 in the annular cavity 61 is used to bundle the wires. At the same time, the annular cavities 61 are evenly distributed, and the wires are bundled in layers, so that the incoming wires are bundled tightly together. The rubber tube 6 starts up, and after the rubber tube 6 elastically shrinks, it wraps the wire. At the same time, the height of the rubber tube 6 is greater than the height of the connecting tube 5, that is, the two ends of the rubber tube 6 protrude from the connecting tube 5. The rubber tube 6 wraps and protects the wire to prevent the wire from contacting the two ends of the connecting tube 5. After the rubber tube 6 elastically shrinks, the rubber plate 8 is pulled to expand synchronously, thereby filling the gap between the rubber tube 6 and the connecting tube 5. At the same time, the rubber plate 8 is an elastic piano-shaped rubber plate, which can shrink accordingly according to the diameter of the wire, thereby ensuring the sealing of the wire entry position.
[0029] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
