Description

Technical Field

[0001] This utility model relates to the field of power supply boxes, specifically to a modular power supply. Background Technology

[0002] The power supply box is the control center that directs the rational distribution of electrical energy among various components in the power supply line. It is the control link that reliably receives the upstream power supply and correctly feeds out the load electrical energy. During normal operation, the circuit can be connected or disconnected by manual or automatic switches. In case of fault or abnormal operation, the circuit can be cut off or an alarm can be triggered by protective electrical appliances.

[0003] A Chinese patent discloses a modular power supply (authorization announcement number CN 221614425 U). This patented technology can solve the problems that most power cabinets are fixed and spliced ​​together by connecting plates and multiple bolts, which is time-consuming, labor-intensive and inefficient.

[0004] The existing power supply box has a one-piece structure and is relatively large, making it difficult to transport and move. Furthermore, the internal wiring is prone to detachment when pulled, affecting the normal operation of the power supply components. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a modular power supply, including an upper plate and side plates. The upper plate is symmetrically arranged vertically, and a side plate is arranged on the inner end of the upper plate. The side plates are connected to the upper plate by a first bolt. The side plates are symmetrically arranged horizontally. A rear plate is screwed to the rear end face of the upper plate by a second bolt. A door is rotatably installed on the front end face of the side plate by a pin. An outer plate is symmetrically installed on the front end face of the rear plate. An inner plate is installed on the inner end of the outer plate. A side plate is arranged between the outer plate and the inner plate. The side plates are connected to the outer plate and the inner plate by a third bolt.

[0006] Preferably, the side plate has a through hole at the outer end, a sleeve is installed at the outer end of the through hole, a through groove is opened at the outer end of the sleeve, and ring buckles are symmetrically arranged in the through groove. The ring buckles are connected by snap-fit. The side plate has a fixing groove symmetrically opened at the front and back, a first spring is installed at the outer end of the fixing groove, a first slider is installed at the other end of the first spring, and an L-shaped frame is installed at the outer end of the first slider.

[0007] Preferably, an adjustment cavity is installed on the outer end of the upper plate, and an adjustment screw is rotatably installed on the left and right side walls of the adjustment cavity through bearings. Adjustment sliders are symmetrically screwed to the outer side walls of the adjustment screws. A baffle is installed on the outer end of the adjustment slider through a fixing bracket. A circular hole is opened on the front end face of the adjustment cavity, and an insertion rod is installed in the circular hole by sliding fit. The insertion rod is inserted into the outer side wall of the adjustment screw.

[0008] The technical effects and advantages of this utility model are as follows:

[0009] 1. The present invention adopts a first bolt and a second bolt structure, which facilitates the disassembly and separation of the upper plate and the side plate, making it easy to disassemble and carry, and avoiding the inconvenience of transportation due to excessive size.

[0010] 2. This utility model adopts a ring buckle structure to limit and fix the connecting wire, so as to prevent the external pulling of the connecting wire from causing it to loosen and fall off at the connection with the power device, which would affect the normal use of the device. The L-shaped frame plays a limiting role for the ring buckle, preventing it from falling off the through groove. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0018] Please see Figures 1-5This embodiment provides a modular power supply, including an upper plate 1 and side plates 2. The upper plate 1 is arranged symmetrically vertically, and the side plates 2 are arranged on the inner side of the upper plate 1. The side plates 2 are connected to the upper plate 1 by a first bolt 11. The side plates 2 are arranged symmetrically horizontally. A rear plate 13 is screwed to the rear end face of the upper plate 1 by a second bolt 12. A door 14 is rotatably installed on the front end face of the side plates 2 by a pin. Outer plates 15 are symmetrically installed on the front end face of the rear plate 13, and inner plates 16 are installed on the inner side of the outer plates 15. A side plate 2 is arranged between the outer plate 15 and the inner plate 16. The side plate 2 is connected to the outer plate 15 and the inner plate 16 by a third bolt 17. During operation, the upper plate 1 and the side plate 2 form a cavity structure, which facilitates the storage of power supply devices. The first bolt 11 and the second bolt 12 can be rotated to remove the upper plate 1 and the side plate 2, thereby separating them for easy disassembly and transport, avoiding the inconvenience of excessive volume. The outer plate 15 and the interior provide positioning and clamping for the side plate 2, further improving the overall stability of the device.

[0019] The side plate 2 has a through hole at its outer end, and a sleeve 18 is installed at the outer end of the through hole. A through groove is opened at the outer end of the sleeve 18, and ring buckles 19 are symmetrically arranged in the through groove. The ring buckles 19 are connected by snap-fit. The side plate 2 has a fixing groove symmetrically opened at the front and back of its outer end. A first spring 21 is installed at the outer end of the fixing groove, and a first slider is installed at the other end of the first spring 21. An L-shaped frame 22 is installed at the outer end of the first slider. During operation, the multiple connecting wires of the internal power device pass through the through hole to connect with the external circuit. The ring buckles 19 press and fix the connecting wires to prevent them from being pulled loose and falling off at the connection point with the power device, which would affect the normal use of the device. The L-shaped frame 22 limits the ring buckles 19 to prevent them from falling off the through groove.

[0020] An adjustment cavity is installed on the outer end of the upper plate 1. An adjustment screw 23 is rotatably installed on the left and right side walls of the adjustment cavity via bearings. An adjustment slider is symmetrically screwed to the outer wall of the adjustment screw 23. A baffle 24 is installed on the outer end of the adjustment slider via a fixing bracket. A circular hole is opened on the front end face of the adjustment cavity. An insert rod 25 is installed in the circular hole by sliding fit. The insert rod 25 is inserted into the outer wall of the adjustment screw 23. During operation, the left and right symmetrical threads of the adjustment screw 23 are opposite in direction. The baffle 24 plays a role in limiting and fixing the first bolt 11 to prevent it from loosening and falling off. The insert rod 25 limits the adjustment screw 23 to prevent it from rotating accidentally. Pulling out the insert rod 25 drives the adjustment screw 23 to rotate, causing the baffle 24 to move inward, thereby enabling the first bolt 11 to be disassembled.

[0021] In actual operation, the upper plate 1 and the side plate 2 form a cavity structure, which facilitates the storage of power supply devices. The first bolt 11 and the second bolt 12 are removed by rotating, thereby separating the upper plate 1 and the side plate 2, which facilitates disassembly and carrying, avoiding the inconvenience of transportation due to excessive size. The outer plate 15 and the interior provide positioning and clamping for the side plate 2, further improving the overall stability of the device.
