Description
Technical Field
[0001] The utility model relates to the technical field of switch cabinets, in particular to a bus connection mechanism of a solid switch cabinet. Background Technique
[0002] The structure of a fixed switch cabinet mainly includes parts such as a busbar chamber, a circuit breaker chamber, and a cable chamber. Generally, the busbar is arranged in a long strip shape as a whole. The busbar is a conductor that plays a key role in a complete set of switch cabinets. Its main function is to connect various electrical equipment between cabinets and inside the cabinets to realize the collection, distribution, and transmission of electric energy.
[0003] After retrieval, a utility model with the Chinese patent publication number CN219204035U discloses a bus connection mechanism, including a busbar plate, a rectangular block, a rectangular cavity, a sliding plate, and a groove. Two rectangular blocks are fixedly connected to the front side of the busbar plate. A rectangular cavity is opened inside the rectangular block, and rectangular holes are opened on the left inner wall and the right inner wall of the rectangular cavity.
[0004] The above device fixes the busbar by inserting two mounting plates and the busbar plate into each other. Therefore, the states of each busbar will also be the same. If one busbar needs to be repaired, the other busbars will also lose their connections, and the operation is relatively inconvenient, leaving room for improvement. Content of the Utility Model
[0005] The purpose of the utility model is to provide a bus connection mechanism of a solid switch cabinet to solve the problems raised in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A bus connection mechanism of a solid switch cabinet, including a bottom plate and a pressing plate. A plurality of busbar bodies are placed at equal distances between the bottom plate and the pressing plate. The same connection component is installed between the bottom plate and the pressing plate. A plurality of limiting components are installed inside the pressing plate. The positions of the plurality of limiting components correspond to the positions of the plurality of busbar bodies respectively. The limiting component includes a mounting groove opened on the outer wall of the top of the pressing plate, and a pressing groove is rotatably connected to the top of one side of the mounting groove through a hinge.
[0007] As a further preferred of this technical solution, two mounting plates are fixedly connected to the outer wall of one side of the pressing groove. The same positioning rod is slidably inserted into the two mounting plates. Springs are sleeved on the outer parts of the two branches of the positioning rod. The two ends of the two springs are fixedly connected to the positioning rod and the two mounting plates respectively. A limiting groove corresponding to the position of the positioning rod is opened on the outer wall of one side of the pressing plate.
[0008] It is possible to separately change the connection state of one or several busbar bodies as needed, ensuring that the states of the other several busbar bodies remain unchanged, making the operation more convenient. If one of the busbar bodies needs to be repaired, just pull the positioning rod outwards, and the tension of the spring will be overcome and it will become longer. The positioning rod will also gradually disengage from the limit groove along the mounting plate. At this time, the pressure groove rotating in the mounting groove can be easily flipped upwards, and the restricted busbar body will be completely exposed to the outside. Conversely, under the restriction of the positioning rod, the position of the pressure groove will be restricted, so that the position of the busbar body can be kept stable.
[0009] As a further optimization of this technical solution, the connection assembly includes four screw rods rotatably connected to the four corners of the outer wall of the top of the bottom plate. The four screw rods are threadedly connected to the same pulling hook, and a knob is fixedly sleeved on the bottom of the circumferential outer wall of one of the screw rods.
[0010] As a further optimization of this technical solution, one sprocket is rotatably connected to each of the four corners of the inner wall of the top of the bottom plate. The four sprockets are coaxially fixed to the four screw rods respectively, and a chain is sleeved between two adjacent sprockets.
[0011] Place the pressure plate on the top of multiple busbar bodies, and then drive one screw rod to rotate through the knob. The sprocket connected to it will be driven to rotate synchronously. The sprocket can drive the other two sprockets to rotate through two chains. Similarly, the fourth sprocket will rotate synchronously, and then the other several screw rods will also rotate simultaneously. Since the pulling hook is connected to the four screw rods, it can only move up and down. When the four screw rods rotate simultaneously, they can drive the pulling hook to move downwards until the pulling hook drives the pressure plate to squeeze the busbar bodies, and multiple busbar bodies will be fixed simultaneously.
[0012] As a further optimization of this technical solution, a card slot corresponding to the position of the pulling hook is opened on the outer wall of the top of the pressure plate.
[0013] As a further optimization of this technical solution, multiple positioning rods are all made of insulating materials.
[0014] As a further optimization of this technical solution, the lead angle of the screw thread of the screw rod is less than the equivalent friction angle.
[0015] The utility model provides a busbar connection mechanism for a solid switch cabinet, which has the following beneficial effects:
[0016] (1) By providing a limit component, the utility model can separately change the connection state of one or several busbar bodies as needed, ensuring that the states of the other several busbar bodies remain unchanged, which makes the operation more convenient. If one of the busbar bodies needs to be repaired, just pull the positioning rod outwards, the tension of the spring will be overcome and it will become longer, and the positioning rod will gradually disengage from the limit groove along the mounting plate. At this time, the pressure groove in the mounting groove can be easily flipped upwards, and the restricted busbar body will be completely exposed to the outside. On the contrary, under the restriction of the positioning rod, the position of the pressure groove will be restricted, so that the position of the busbar body can be kept stable.
[0017] (2) By providing a connection component, place the pressing plate on the tops of multiple busbar bodies, and then drive a lead screw to rotate through a knob. The sprocket connected to it will be driven to rotate synchronously. The sprocket can drive two other sprockets to rotate through two chains. Similarly, the fourth sprocket will rotate synchronously, and then several other lead screws will also rotate simultaneously. Since the pulling hook is connected to the four lead screws, it can only move up and down. When the four lead screws rotate simultaneously, they can drive the pulling hook to move downwards until the pulling hook drives the pressing plate to squeeze the busbar bodies, and multiple busbar bodies will be fixed simultaneously.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model.
[0024] The utility model provides the following technical solutions: As shown in Figure 1 and Figure 3As shown in the figure, in this embodiment, a busbar connection mechanism of a solid switch cabinet includes a bottom plate 1 and a pressing plate 2. A plurality of busbar bodies 3 are arranged at equal distances between the bottom plate 1 and the pressing plate 2. A same connection component 5 is installed between the bottom plate 1 and the pressing plate 2. A plurality of limiting components 4 are installed inside the pressing plate 2. The positions of the plurality of limiting components 4 correspond to the positions of the plurality of busbar bodies 3 respectively. The limiting component 4 includes an installation groove 401 opened on the outer wall of the top of the pressing plate 2. A pressing groove 402 is rotatably connected to the top of one side of the installation groove 401 through a hinge.
[0025] Two mounting plates 403 are fixedly connected to the outer wall of one side of the pressing groove 402. The same positioning rod 404 is slidably inserted into the two mounting plates 403. A spring 405 is sleeved on the outer portions of the two support rods of the positioning rod 404. The two ends of the two springs 405 are fixedly connected to the positioning rod 404 and the two mounting plates 403 respectively. A limiting groove 406 corresponding to the position of the positioning rod 404 is opened on the outer wall of one side of the pressing plate 2.
[0026] If one of the busbar bodies 3 needs to be repaired, as long as the positioning rod 404 is pulled outwards, the pulling force of the spring 405 will be overcome and become longer. The positioning rod 404 will also gradually disengage from the limiting groove 406 along the mounting plate 403. At this time, the pressing groove 402 in the installation groove 401 can be easily flipped upwards, and the restricted busbar body 3 will be completely exposed to the outside. On the contrary, under the restriction of the positioning rod 404, the position of the pressing groove 402 will be restricted, so that the position of the busbar body 3 can be kept stable.
[0027] As Figure 2 and Figure 4 As shown in the figure, the connection component 5 includes four lead screws 501 rotatably connected to the four corners of the outer wall of the top of the bottom plate 1. The four lead screws 501 are threadedly connected to the same pulling hook 502. A knob is fixedly sleeved on the bottom of the outer wall of the circumference of one of the lead screws 501.
[0028] One sprocket 504 is rotatably connected to each of the four corners of the inner wall of the top of the bottom plate 1. The four sprockets 504 are coaxially fixed to the four lead screws 501 respectively. A chain 505 is sleeved on two adjacent sprockets 504.
[0029] A card slot 503 corresponding to the position of the pulling hook 502 is opened on the outer wall of the top of the pressing plate 2. When the pulling hook 502 enters the card slot 503, the position of the pressing plate 2 can be ensured to be more stable.
[0030] Place the pressing plate 2 on top of multiple busbar bodies 3. Then, drive a lead screw 501 to rotate through a knob. The sprocket 504 connected to it will be driven to rotate synchronously. The sprocket 504 can drive the other two sprockets 504 to rotate through two chains 505. Similarly, the fourth sprocket 504 will rotate synchronously. Furthermore, several other lead screws 501 will also rotate simultaneously. Since the pulling hook 502 is connected to the four lead screws 501, it can only move up and down. When the four lead screws 501 rotate simultaneously, they can drive the pulling hook 502 to move downward until the pulling hook 502 drives the pressing plate 2 to squeeze the busbar bodies 3, and multiple busbar bodies 3 will be fixed simultaneously.
[0031] As Figure 3 shown, multiple positioning rods 404 are all made of insulating materials, so that workers will not get an electric shock after contacting the positioning rods 404.
[0032] As Figure 4 shown, the lead angle of the lead screw 501 is less than the equivalent friction angle, making it have a self-locking property.
[0033] The present utility model provides a busbar connection mechanism for a solid switch cabinet, and the specific working principle is as follows:
[0034] When the device works, place the pressing plate 2 on top of multiple busbar bodies 3. Then, drive a lead screw 501 to rotate through a knob. The sprocket 504 connected to it will be driven to rotate synchronously. The sprocket 504 can drive the other two sprockets 504 to rotate through two chains 505. Similarly, the fourth sprocket 504 will rotate synchronously. Furthermore, several other lead screws 501 will also rotate simultaneously. Since the pulling hook 502 is connected to the four lead screws 501, it can only move up and down. When the four lead screws 501 rotate simultaneously, they can drive the pulling hook 502 to move downward until the pulling hook 502 drives the pressing plate 2 to squeeze the busbar bodies 3, and multiple busbar bodies 3 will be fixed simultaneously. If one of the busbar bodies 3 needs to be repaired, as long as the positioning rod 404 is pulled outwards, the tension of the spring 405 will be overcome and it will become longer, and the positioning rod 404 will also gradually disengage from the limit groove 406 along the mounting plate 403. At this time, the pressing groove 402 rotating in the mounting groove 401 can be easily flipped upwards, and the restricted busbar body 3 will be completely exposed to the outside. On the contrary, under the restriction of the positioning rod 404, the position of the pressing groove 402 will be restricted, so that the position of the busbar body 3 can be kept stable.
[0035] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
