Description

Technical Field

[0001] The utility model relates to the technical field of distribution switch boxes, and specifically relates to a distribution switch control box. Background Art

[0002] Household distribution switches, also known as air switches or air circuit breakers, are mainly used in low-voltage distribution networks and electric drive systems, and have control and multiple protection functions. The distribution switches are generally fixedly installed on the mounting bars inside the control box. Specifically, they are clamped to the card slots at the bottom of the distribution switches by the convex edges on both sides of the mounting bars, so that the distribution switches can be conveniently installed inside the control box;

[0003] When repairing the distribution switches, sometimes the damaged distribution switches on the mounting bars are disassembled. Since multiple distribution switches are all slidably clamped on the convex edges of the mounting bars, when disassembling a single damaged distribution switch, the entire mounting bar and multiple distribution switches need to be disassembled at the same time, increasing the workload of replacing the distribution switches. During maintenance, after the staff opens the protective cover at the open end of the control box, the protective cover may automatically close. Therefore, a hand is needed to hold the protective cover to ensure that the protective cover will not automatically close, which is rather troublesome. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a distribution switch control box to solve the problems mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A distribution switch control box includes a switch box. Both ends of the switch box are detachably fixed with mounting seats. A first mounting bar is detachably fixed between the two mounting seats. A second mounting bar is detachably fixed to the bottom of the first mounting bar. Multiple switch bodies are clamped and installed on the outer sides of the first mounting bar and the second mounting bar. A face mask is detachably fixed to the open end of the switch box. An operation cavity is opened on the front side of the face mask. A protective cover is rotatably connected to the open side of the operation cavity. A shaft rod is slidably clamped to the top of the protective cover. One end of the shaft rod is screwed to the face mask, and the other end of the shaft rod is slidably inserted into the face mask.

[0007] Furthermore: Both ends of the second mounting bar are fixed with mounting plates, and the mounting plates are detachably fixed to the first mounting bar by screws.

[0008] Furthermore: A convex edge is fixed to one edge of both the first mounting bar and the second mounting bar, and a card slot that is movably clamped to the convex edge is opened at the bottom of the switch body.

[0009] Furthermore, the mounting base is detachably and fixedly connected to the switch box by screws. Limiting blocks are fixed on both sides of the mounting base, and a positioning block is fixed inside the mounting base. The positioning block is detachably and fixedly connected to the first mounting strip by screws.

[0010] Furthermore, mounting blocks are fixed at both ends inside the switch box, and the face mask is detachably and fixedly connected to the mounting blocks by screws.

[0011] Furthermore, a first fixing block and a second fixing block are respectively fixed at both ends on the rear side of the face mask. A threaded column screwed to the first fixing block is fixed at one end of the shaft rod, and a circular hole rotatably inserted with the shaft rod is opened at one end of the second fixing block.

[0012] Furthermore, a sliding groove is formed on the outer side of the shaft rod, and a sliding block slidably connected to the sliding groove is fixed at the top of the protective cover. The length of the sliding block is less than the length of the sliding groove.

[0013] Furthermore, a rectangular through hole for exposing the switch body is formed through the middle of the face mask, and a notch is formed at the bottom of the face mask.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By setting the traditional integrated mounting strip into the first mounting strip and the second mounting strip, and the distance between the first mounting strip and the second mounting strip can be adjusted. When fixing the switch, move the second mounting strip away from the first mounting strip, so that the convex ribs on the first mounting strip and the second mounting strip can be clamped into the grooves on the switch, and then fix the second mounting strip to the first mounting strip by screws, which is convenient for fixing multiple switches at the same time;

[0016] When disassembling a single damaged switch, disassemble the second mounting strip and move it towards the first mounting strip, so that the convex rib on the second mounting strip leaves the groove on the switch, which is convenient for removing the damaged switch separately from the first mounting strip and the second mounting strip, saving the need to disassemble the entire mounting strip and multiple switches at the same time when disassembling a single damaged switch in the traditional way, saving manpower and improving the efficiency of switch maintenance and disassembly.

[0017] 2. By sliding and clamping a shaft rod at the top of the protective cover, and one end of the shaft rod is screwed to the face mask through a threaded column. During the process of rotating the protective cover upward to open it, the protective cover drives the shaft rod to rotate through the cooperation of the sliding block and the sliding groove, and the shaft rod drives the threaded column to rotate synchronously. By using the threaded column that can be screwed and rotated in the first fixing block and stay at any position, the shaft rod drives the protective cover not to automatically close after rotating and opening, eliminating the need to hold the protective cover with one hand to ensure that the protective cover does not automatically close during maintenance.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1, please refer to Figures 1-5 , in the embodiment of the present utility model, a distribution switch control box includes a switch box 100. Mounting seats 110 are detachably fixed at both ends of the switch box 100. A first mounting strip 200 is detachably fixed between the two mounting seats 110. A second mounting strip 300 is detachably fixed to the bottom of the first mounting strip 200. A plurality of switch bodies 400 are snap-fitted and installed on the outer sides of the first mounting strip 200 and the second mounting strip 300. A mask 500 is detachably fixed to the open end of the switch box 100. An operation cavity 540 is formed on the front side of the mask 500. A protective cover 600 is rotatably connected to the open side of the operation cavity 540. A shaft rod 610 is slidably snap-fitted to the top of the protective cover 600. One end of the shaft rod 610 is screwed to the mask 500, and the other end of the shaft rod 610 is slidably inserted into the mask 500.

[0026] Specifically, by setting the traditional single integrated installation strip into installation strip one 200 and installation strip two 300 that can adjust the distance between each other, when disassembling a single damaged switch, only need to move up installation strip two 300 to hang the switch alone on installation strip one 200, which is convenient for targeting and removing the damaged switch, saving the need to disassemble the entire installation strip and multiple switches simultaneously when disassembling a single damaged switch in the traditional way, saving manpower and improving the efficiency of switch maintenance and disassembly. By sliding and inserting a shaft rod 610 at the top of the protective cover 600, and one end of the shaft rod 610 is screwed and connected to the mask 500. During the process of opening the protective cover 600, due to the characteristic of position locking after screw thread engagement, the shaft rod 610 can drive the protective cover 600 to rotate and stay at any opening and closing position, eliminating the need to hold the protective cover 600 with one hand during maintenance to ensure that the protective cover 600 will not automatically close.

[0027] As Figure 5 shown, in this embodiment, mounting plates 310 are fixed at both ends of installation strip two 300, and the mounting plates 310 are detachably and fixedly connected to installation strip one 200 by screws. During the process of fixing the switch, after moving down installation strip two 300 until it abuts against the corresponding position limiting block 111, use screws to fix the mounting plates 310 on installation strip two 300 to installation strip one 200, thereby realizing the clamping and fixing of the switch by using the convex ribs of installation strip one 200 and installation strip two 300.

[0028] As Figure 5 shown, in this embodiment, convex ribs 320 are fixed on one edge of both installation strip one 200 and installation strip two 300, and a card slot for active clamping connection with the convex rib 320 is opened at the bottom of the switch body 400. Convex ribs 320 are fixed above installation strip one 200 and below installation strip two 300. The convex ribs 320 can be clamped into the card slot of the switch in the prior art, facilitating the detachable installation of the switch between installation strip one 200 and installation strip two 300.

[0029] As Figure 4 shown, in this embodiment, the mounting base 110 is detachably and fixedly connected to the switch box 100 by screws. Limiting blocks 111 are fixed on both sides of the mounting base 110, and a positioning block is fixed inside the mounting base 110. The positioning block is detachably and fixedly connected to installation strip one 200 by screws. The limiting blocks 111 facilitate restricting the positions of installation strip one 200 and installation strip two 300. When disassembling installation strip one 200, the screws on the positioning block can be disassembled, and then installation strip one 200 can be pulled out along the limiting blocks 111.

[0030] As Figure 4As shown, in this embodiment, mounting blocks 120 are fixed at both ends inside the switch box 100. The mask 500 is detachably and fixedly connected to the mounting blocks 120 by screws, so that the mask 500 is detachably mounted on the open side of the switch box 100.

[0031] During specific implementation, when it is necessary to remove a damaged switch, first remove the mask 500 from the switch box 100, then loosen the screws on the mounting plate 310 to disengage the mounting plate 310 from the first mounting strip 200, and then move the second mounting strip 300 upward to disengage the second mounting strip 300 from the card slot at the bottom of the switch. At this time, the switch is only hooked on the first mounting strip 200, and the damaged switch can be directly removed.

[0032] Embodiment 2, on the basis of Embodiment 1, in order to prevent the protective cover 600 from automatically closing after being opened.

[0033] As Figure 3 shown, in this embodiment, a first fixing block 510 and a second fixing block 520 are respectively fixed at both ends on the rear side of the mask 500. One end of the shaft rod 610 is fixed with a threaded column 611 that is screwed and connected to the first fixing block 510, and a round hole for rotatably inserting the shaft rod 610 is opened at one end of the second fixing block 520.

[0034] In this embodiment, when the protective cover 600 is rotated and opened, the protective cover 600 drives the shaft rod 610 to rotate. The shaft rod 610 drives the threaded column 611 to screw out a certain distance from inside the first fixing block 510. At this time, the shaft rod 610 slides inside the protective cover 600, and one end of the shaft rod 610 away from the threaded column 611 moves into the round hole by the above distance. The shaft rod 610 is screwed and fixed in the opened position by the threaded column 611 and no longer rotates, so that the protective cover 600 will not automatically close.

[0035] As Figure 3 shown, in this embodiment, a chute 612 is opened on the outer side of the shaft rod 610. A slider that is slidably connected to the chute 612 is fixed at the top of the protective cover 600. The length of the slider is less than the length of the chute 612. The slider on the protective cover 600 is inserted into the chute 612. Therefore, when the protective cover 600 rotates, it will drive the shaft rod 610 to rotate. The length of the slider being less than the length of the chute 612 ensures that the chute 612 can slide outside the slider when the protective cover 600 rotates and opens.

[0036] As Figure 2 and Figure 3 shown, in this embodiment, a rectangular through hole 530 for exposing the switch body 400 is formed through the middle of the mask 500. A notch 550 is opened at the bottom of the mask 500. The rectangular through hole 530 exposes the switch body 400 inside the operation cavity 540, which is convenient for the user to operate the switch. The notch 550 on the mask 500 is convenient for opening the protective cover 600.

[0037] During specific implementation, the protective cover 600 is rotated upward from the notch 550 position of the face mask 500. The protective cover 600 drives the shaft rod 610 to rotate. The threaded column 611 at one end of the shaft rod 610 is screwed out of the first fixing block 510 by a certain distance. During this process, the shaft rod 610 slides inside the protective cover 600. The end of the shaft rod 610 away from the threaded column 611 is rotationally inserted into the round hole by the same distance. By using the fact that the threaded column 611 can stay in the rotated position after screwing, the shaft rod 610 will not automatically rotate again after rotation, and thus the opened protective cover 600 will not automatically rotate and close.

[0038] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
