Description

Technical Field

[0001] This utility model relates to the field of distribution box guide rail technology, specifically to a guide rail for a distribution box. Background Technology

[0002] A distribution box is a low-voltage distribution box in which switching equipment, measuring instruments, protective electrical appliances and auxiliary equipment are assembled in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. The guide rail of the distribution box plays an important role in the power distribution system. The guide rail can fix various electrical appliances in the distribution box, such as circuit breakers and relays, to ensure that they will not be displaced or damaged due to vibration during operation.

[0003] Existing distribution box guide rails have a simple structure and cannot be adjusted after being fixed inside the distribution box with bolts. Therefore, a new type of distribution box guide rail is proposed. By rotating a long screw, the limiting strip and the guide rail on its outer side can be moved up and down, thereby adjusting the position of the guide rail and facilitating the installation of electrical components. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a guide rail for a distribution box. Rotating the long screw pushes the limiting strip and the guide rail on its outer side to move up and down, which can adjust the position of the guide rail and facilitate the installation of electrical components.

[0005] The technical solution adopted by this utility model to solve its technical problem is a guide rail for a distribution box, including a guide rail, a pusher assembly is provided on the top of the guide rail, the pusher assembly includes a cylinder that is fixed to the top of the guide rail at equal intervals by a flange, a compression spring is fixed to the bottom of the cylinder by bolts, a support rod is sleeved on the top of the cylinder, and a pusher cover is connected to the top of the support rod by a threaded groove.

[0006] The guide rail has mounting bases at both ends with protective sleeves welded to the top. A long screw is sleeved inside the protective sleeve through a bearing. Internal threaded sleeves are fixedly sleeved at both ends inside the guide rail, and the internal threaded sleeves are sleeved on the outside of the long screw.

[0007] By adopting the above technical solution, the compression spring pushes the support rod and the pusher cover to move, thereby pushing the electrical components locked on the outside of the guide rail to prevent them from loosening. The rotation of the long screw pushes the inner threaded sleeve and the guide rail on the outside to move up and down, which can adjust the position of the guide rail.

[0008] Specifically, the mounting base has limit strips welded to both sides inside, and the guide rail has limit grooves equidistantly opened on both sides, with the limit grooves sleeved on the outside of the limit strips.

[0009] Specifically, the bottom end of the long screw is rotatably connected to the bottom of the mounting base via a bearing, and the bottom ends of both sides of the mounting base are welded with fixing ears.

[0010] Specifically, the bottom end of the support rod located inside the cylinder is fixed to a limit block by bolts, and the top end of the compression spring is fixed to the bottom of the limit block by bolts.

[0011] Specifically, the pusher cover is made of fiberglass material, and structural grooves are equidistantly opened through the top of the pusher cover.

[0012] The beneficial effects of this utility model are:

[0013] (1) The guide rail of the distribution box described in this utility model uses a working rotating long screw. When the long screw rotates, it pushes the inner threaded sleeve and the guide rail on the outside to move up and down, which can adjust the position of the guide rail and facilitate the installation of electrical components such as circuit breakers and relays.

[0014] (2) When the circuit breaker, relay and other electrical components are locked on the guide rail of the distribution box described in this utility model, the compression spring pushes the circuit breaker, relay and other electrical components locked on the guide rail through the support rod and the push cover, so that they are not easy to shake.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Rotating the long screw pushes the limiting strip and its outer guide rail up and down, adjusting the position of the guide rail and facilitating the installation of electrical components, such as... Figure 1-4As shown, the guide rail of the distribution box of this utility model includes a guide rail 1, a pusher assembly 3 is provided on the top of the guide rail 1, the pusher assembly 3 includes a cylinder 301 that is equidistantly fixed to the top of the guide rail 1 by a flange, a compression spring 304 is fixed to the bottom of the cylinder 301 by bolts, a support rod 302 is sleeved on the top of the cylinder 301, and a pusher cover 303 is connected to the top of the support rod 302 by a threaded groove;

[0023] The guide rail 1 has mounting bases 2 at both ends and a protective sleeve 4 welded to the top. A long screw 5 is sleeved inside the protective sleeve 4 through a bearing. An internal threaded sleeve 7 is fixedly sleeved at both ends inside the guide rail 1. The internal threaded sleeve 7 is sleeved on the outside of the long screw 5.

[0024] In use, the compression spring 304 pushes the support rod 302 and the pusher cover 303 to move, thereby pushing the electrical components engaged on the outside of the guide rail 1 to prevent them from becoming loose. The long screw 5 rotates to push the inner threaded sleeve 7 and the guide rail 1 on the outside to move up and down, which can adjust the position of the guide rail 1.

[0025] For example, such as Figure 2 , Figure 3 As shown, the present invention also includes, on both sides of the inner side of the mounting base 2, a limiting strip 6 is welded, and on both sides of the guide rail 1, a limiting groove 8 is equally spaced, and the limiting groove 8 is sleeved on the outside of the limiting strip 6.

[0026] When in use, the limit bar 6 and the limit groove 8 can limit the movement of the guide rail 1 without affecting it, thus preventing the guide rail 1 from tilting.

[0027] For example, such as Figure 2 As shown, the present invention also includes a long screw 5 whose bottom end is rotatably connected to the bottom of the mounting base 2 via a bearing, and a fixing lug 9 is welded to the bottom ends of both sides of the mounting base 2.

[0028] In use, the bottom end of the long screw 5 is rotatably connected to the bottom of the mounting base 2 through the bearing, which makes the structure stable. The mounting base 2 can be fixed in the distribution box by bolts through the fixing lug 9.

[0029] For example, such as Figure 4 As shown, the present invention also includes a limit block 305 fixed to the bottom end of the support rod 302 inside the cylinder 301 by bolts, and the top end of the compression spring 304 fixed to the bottom of the limit block 305 by bolts.

[0030] During use, the compression spring 304 pushes the support rod 302 upward through the limiting block 305, which can prevent the support rod 302 from falling out of the cylinder 301.

[0031] For example, such as Figure 3As shown, the present invention also includes a pusher cover 303 made of glass fiber material, and structural grooves 10 are equidistantly provided on the top of the pusher cover 303.

[0032] When in use, the pusher cover 303 made of fiberglass material has high strength and good insulation. The setting of the structural groove 10 can reduce its weight without affecting the structural stability of the pusher cover 303.

[0033] In use, personnel use bolts to fix the mounting base 2 inside the distribution box via the fixing lug 9;

[0034] The working rotating long screw 5 pushes the internal threaded sleeve 7 to move up and down when the long screw 5 rotates, thereby driving the guide rail 1 to move up and down. The position of the guide rail 1 can be adjusted, which facilitates the installation of electrical components such as circuit breakers and relays.

[0035] When the guide rail 1 moves up and down, the limiting groove 8 slides outside the limiting strip 6, which can limit the movement of the internal threaded sleeve 7 without affecting it and prevent the internal threaded sleeve 7 from tilting.

[0036] When personnel attach electrical components such as circuit breakers and relays to the guide rail 1, they push the pusher cover 303 and its bottom support rod 302 downwards. The downward movement of the support rod 302 pushes the compression spring 304 through the limit block 305, compressing it. The compression spring 304 then pushes the electrical components such as circuit breakers and relays attached to the guide rail 1 through the support rod 302 and the pusher cover 303, making them less prone to vibration.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
