Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically a distribution box that is easy to assemble and disassemble. Background Technology

[0002] Distribution boxes are electrical equipment characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint, and environmental benefits.

[0003] In the process of realizing this utility model, the inventors discovered the following problems in the prior art that have not been solved: Although the existing distribution boxes have good storage and protection effects, in order to control the size of the distribution boxes, the internal power distribution equipment is mostly compactly clamped on the mounting plate. If maintenance or replacement is required later, the distance between adjacent mounting plates is small, so assembly and disassembly are time-consuming and laborious, and improvements are urgently needed. Therefore, we propose a distribution box that is easy to assemble and disassemble. Utility Model Content

[0004] The purpose of this utility model is to provide a power distribution box that is easy to assemble and disassemble, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power distribution box that is easy to assemble and disassemble, comprising a cabinet and a connecting rod, wherein a top cover is placed on the top of the cabinet, and a uniformly arrayed mounting plate is placed inside the cabinet, and there are three sets of mounting plates in total;

[0006] Rod slots are provided inside both sides of the cabinet, and support blocks are fixedly installed at the four corners of the bottom of the cabinet.

[0007] Both sides of the lower surface of the top cover are fixedly installed with insert rods, and the insert rods are locked in the rod grooves. The top and bottom of the insert rods are provided with rod holes. The middle part of the lower surface of the top cover is fixedly connected to the mounting plate on the same side by a support rod.

[0008] A hollow block is placed inside the cabinet on the side near the mounting plate. An inner rod moves through every two adjacent hollow blocks, and a stop block is fixedly installed at both ends of the inner rod.

[0009] The mounting plate and the bottom wall of the cabinet are respectively fixedly connected to the hollow block on the same side, and a T-shaped block is fixedly installed on the front side of the mounting plate;

[0010] A horizontal bar is movably inserted through the side of the cabinet near the rod hole, and the horizontal bar is locked in the rod hole on the same side. It can be used in conjunction with components such as support rods, insertion rods, and hollow blocks. During the use of the distribution box, the top cover can be moved upward by applying force, and the insertion rod will gradually move upward in the rod groove. The top cover will move upward simultaneously with the mounting plate via the support rod, and the adjacent hollow blocks will separate. The lower hollow block will be limited by the inner rod and the stop block. After the top cover moves upward enough, the horizontal bar will be reinserted into the rod hole to limit the insertion rod. At this time, the distance between multiple mounting plates is effectively increased, which facilitates later maintenance and assembly / disassembly operations.

[0011] As an optional solution to the technical solution of this application, a limiting plate is fixedly installed on the outer end of the crossbar, and a tension spring is sleeved on the outer side of the crossbar, with both ends of the tension spring being fixedly connected to the limiting plate and the cabinet respectively. A connecting rod is fixedly installed on the outer side of both sets of limiting plates, which can be used in conjunction with the connecting rod and tension spring. When it is necessary to raise the insertion rod, the connecting rod can be held with one hand and force can be applied to move the two sets of crossbars outward. After the insertion rod is moved into place, the connecting rod is released, and the tension spring drives the crossbar to be inserted into the rod hole. This structural design allows a single person to complete the lifting and limiting without the assistance of others, and the usage effect is quite ideal.

[0012] As an optional solution to the technical solution of this application, the bottom ends of the four sets of support blocks are all fixedly installed with positioning plates, and positioning holes are opened on both sides of the positioning plates. Bolts can be moved through the positioning holes of the positioning plates and screwed to the components preset on the support, for the detachable and stable positioning of the box.

[0013] As an optional solution to the technical solution of this application, an indicator sign is fixedly installed on the outside of the connecting rod, and the indicator sign is fixed by welding. The text on the indicator sign can inform the operator of the corresponding procedures, making it easy for novice personnel to understand and use.

[0014] As an optional solution to the technical solution of this application, the shape of the crossbar is adapted to the contour of the rod hole, and the shape of the insertion rod is adapted to the contour of the rod groove, so that the positioning component is adapted to the design, which can prevent shaking and loosening, and ensure the stability of the limit.

[0015] As an optional solution to the technical solution of this application, a conduit is provided in the middle of the bottom wall of the cabinet, and a rubber ring is fixedly installed inside the conduit. Cables can be laid through the conduit, and the rubber ring is used to protect the wires from wear.

[0024] 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.

[0025] Please see Figure 1-3This utility model provides a technical solution: a power distribution box that is easy to assemble and disassemble, including a cabinet 1 and connecting rods 4. A conduit is connected to the middle of the bottom wall of the cabinet 1, and a rubber ring is fixedly installed inside the conduit. The conduit can be used for wiring, and the rubber ring is used for the protection of the wires against wear. A top cover 2 is placed on the top of the cabinet 1. A uniform array of mounting plates 3 is placed inside the cabinet 1, and there are three sets of mounting plates 3. Rod grooves 11 are opened in the inner side walls of the cabinet 1. Support blocks 12 are fixedly installed at the four corners of the bottom of the cabinet 1. Positioning plates are fixedly installed at the bottom of the four sets of support blocks 12. Positioning holes are opened on both sides of the positioning plates. Bolts can be moved through the positioning holes of the positioning plates and screwed to the components preset on the supports for the detachable and stable positioning of the box. Insert rods 22 are fixedly installed on both sides of the lower surface of the top cover 2. The insert rod 22 is positioned within the rod groove 11. Rod holes 23 are provided at the top and bottom of the insert rod 22. The lower surface of the top cover 2 is fixedly connected to the mounting plate 3 on the same side via a support rod 21. A hollow block 32 is placed inside the cabinet 1 near the mounting plate 3. An inner rod 34 extends through each pair of adjacent hollow blocks 32, and stops 33 are fixedly installed at both ends of the inner rod 34. The mounting plate 3 and the bottom wall of the cabinet 1 are fixedly connected to the hollow blocks 32 on the same side. A T-shaped block 31 is fixedly installed on the front side of the mounting plate 3. A horizontal bar 52 extends through the cabinet 1 near the rod hole 23, and the horizontal bar 52 is positioned within the rod hole 23 on the same side. The shape of the horizontal bar 52 matches the contour of the rod hole 23, and the shape of the insert rod 22 matches the contour of the rod groove 11. This design adapts the positioning components, preventing shaking and loosening, and ensuring the stability of the limit position.

[0026] In this technical solution, components such as support rod 21, insertion rod 22, and hollow block 32 can be used together. During the use of the distribution box, the top cover 2 can be moved upward by applying force. The insertion rod 22 moves upward gradually in the rod groove 11. The top cover 2 moves upward synchronously with the mounting plate 3 via the support rod 21. The adjacent hollow blocks 32 are separated, and the lower hollow block 32 is limited by the inner rod 34 and the stop block 33. After the top cover 2 moves upward in sufficient length, the crossbar 52 is reinserted into the rod hole 23 to limit the insertion rod 22. At this time, the spacing between multiple sets of mounting plates 3 is effectively increased, which facilitates later maintenance and assembly / disassembly operations.

[0027] In some technical solutions, a limit plate 5 is fixedly installed on the outer end of the crossbar 52, and a tension spring 51 is sleeved on the outer side of the crossbar 52. The two ends of the tension spring 51 are fixedly connected to the limit plate 5 and the cabinet 1 respectively. A connecting rod 4 is fixedly installed on the outer side of both sets of limit plates 5. An indicator 41 is fixedly installed on the outer side of the connecting rod 4. The indicator 41 is fixed by welding. The corresponding procedures can be informed to the operator through the text on the indicator 41, which is convenient for novice personnel to understand and use.

[0028] In this technical solution, components such as connecting rod 4 and tension spring 51 can be used together. When it is necessary to raise the insertion rod 22, one hand can hold the connecting rod 4 and apply force to move the two sets of crossbars 52 outward. After the insertion rod 22 moves into place, the connecting rod 4 is released, and the tension spring 51 drives the crossbars 52 to be inserted into the rod hole 23. With this structural design, one person can complete the lifting and limiting without the assistance of others, and the effect is quite ideal.

[0029] Working principle: It should be noted that this utility model is a distribution box that is easy to assemble and disassemble. All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be known to those skilled in the art through technical manuals or conventional test methods.

[0030] When using a distribution box that is easy to assemble and disassemble, the distribution box is placed in a suitable area and then fixed by the support block 12. During this process, the power distribution equipment can be fixed by the mounting plate 3 and the T-shaped block 31 on its front side for the storage and protection of the power distribution equipment.

[0031] By incorporating a support rod 21, a plug rod 22, and a hollow block 32, during the use of the distribution box, the top cover 2 can be moved upwards by applying force. The plug rod 22 gradually moves upwards within the rod slot 11, and the top cover 2, via the support rod 21, simultaneously moves the mounting plate 3 upwards. This causes the adjacent hollow blocks 32 to separate, and the inner rod 34 and the stop block 33 limit the movement of the lower hollow block 32. After the top cover 2 has moved upwards sufficiently, the crossbar 52 is reinserted into the rod hole 23, further limiting the movement of the plug rod 22. The spacing between the multiple mounting plates 3 is effectively increased, which facilitates later maintenance and assembly / disassembly operations. With the addition of connecting rod 4 and tension spring 51, when it is necessary to raise the insertion rod 22, one can hold the connecting rod 4 with one hand and apply force to move the two sets of crossbars 52 outward. After the insertion rod 22 moves into place, the connecting rod 4 is released, and the tension spring 51 drives the crossbar 52 to insert into the rod hole 23. This structural design allows one person to complete the lifting and limiting without the assistance of others, and the usage effect is quite ideal.
