Description

Technical Field

[0001] This application relates to the technical field of circuit breakers, and more specifically, to a circuit breaker support device. Background Art

[0002] A circuit breaker is a switching device that can close, carry, and interrupt the current under normal circuit conditions and can also close, carry, and interrupt the current under abnormal circuit conditions within a specified time. Circuit breakers are generally installed on a circuit breaker support plate. However, there are some inconveniences in the current circuit breaker support plate. One is that circuit breakers are generally fixed to the support plate by screws. However, circuit breakers have different specifications and sizes, so the current circuit breaker support device has poor versatility.

[0003] In this regard, Chinese Patent Application No. CN202121333905.2 discloses a circuit breaker support plate. This solution mainly sets a connection body. The connection body is connected to the support main board through a connection component. Threaded holes are provided on the connection body. The distance between the connection bodies can be adjusted according to the position of the screw holes on the circuit breaker to fix circuit breakers of different models.

[0004] However, in the process of the applicant of the present application implementing the technical solution in the embodiment of the present application, it is found that the above technology has at least the following technical problems:

[0005] The support main board and the clamping protrusion are connected in a mortise and tenon manner, which requires high processing precision. All threaded holes also need to be machined in advance on the connection body, but only a few of them will actually be used. Therefore, the overall structure cost is relatively high. Utility Model Content

[0006] To make up for the above deficiencies, this application provides a circuit breaker support device, aiming to improve the problems mentioned in the above background art.

[0007] An embodiment of this application provides a circuit breaker support device, including a bottom plate. Horizontal grooves are vertically arranged in an array on the bottom plate. A transfer member is horizontally slidably connected in the horizontal grooves. The transfer member is detachably connected to the bottom plate. Tooth teeth are arranged in an array on the edge of the horizontal grooves and engage with the transfer member. Screws are penetrated through the transfer member, and the screws are screwed to an external circuit breaker.

[0008] In a specific implementation, mounting holes are provided on the bottom plate.

[0009] In the above implementation process, the mounting holes are used to install the bottom plate into a power distribution cabinet or other equipment, and multiple bottom plates can also be spliced and used.

[0010] In a specific implementation, the screws are sheep's horn screws.

[0011] In the above implementation process, the sheep's horn screw facilitates manual screwing operation, realizes tool-free operation, and is easy to operate.

[0012] In a specific implementation scheme, the adapter includes a T-shaped slider, a strip-shaped through groove is provided on the slider, and the screw movably penetrates through the through groove.

[0013] In a specific implementation scheme, the slider engages with the teeth on the edge of the transverse groove.

[0014] In the above implementation process, the slider drives the screw to slide horizontally on the transverse groove, so as to adjust the position of the screw according to the position of the threaded hole of the actual circuit breaker. When the screw is tightened, the slider engages with the teeth, and the position can be fixed and is not easy to loosen. The teeth on the edge of the transverse groove here mainly play the role of fixing the position, and the requirement for processing accuracy is not high. The hobbing method can be used for processing, and the cost is low. The T-shaped slider can be stuck into the transverse groove and slide.

[0015] In a specific implementation scheme, the adapter further includes an adjusting block, a through hole is provided on the adjusting block, and the screw movably penetrates through the through hole.

[0016] In a specific implementation scheme, the adjusting block engages with the slider in a tooth shape.

[0017] In a specific implementation scheme, the adjusting block and the slider are respectively located on both sides of the bottom plate, and the adjusting block abuts against the external circuit breaker.

[0018] In the above implementation process, the adjusting block and the slider are respectively placed on both sides of the bottom plate, so that the adjusting block fits against the back of the circuit breaker. By adjusting the up and down position of the adjusting block, the up and down position of the screw is changed, so as to finely adjust the vertical height of the screw. When the screw is tightened, the adjusting block and the slider are engaged together to lock the relative position. Such a setting can improve the matching degree between the screw and the circuit breaker, and can also reduce the density of the transverse groove, further reducing the processing cost.

[0019] Compared with the prior art, the beneficial effects of the present application are: according to the threaded hole on the back of the circuit breaker, the adapter is installed on the transverse groove at an appropriate height, and is horizontally moved on the transverse groove for adjustment. Then, the circuit breaker and the adapter are tightened on the bottom plate by using the screw, and the engagement between the teeth on the bottom plate and the adapter is used to improve the connection firmness. Since the adapter is installed according to the actual situation, there will be no waste, and the transverse groove on the bottom plate is also easy to process. Therefore, the structural cost can be effectively reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application.

[0027] Please refer to Figures 1-4 , the present application provides a breaker support device, including a bottom plate 10. Transverse grooves are vertically arranged in an array on the bottom plate 10. An adapter 20 is horizontally slidably connected in the transverse grooves. The adapter 20 is detachably connected to the bottom plate 10. Teeth are arranged in an array along the edge of the transverse grooves and engage with the adapter 20. A screw 30 is penetrated through the adapter 20, and the screw 30 is screwed to an external breaker. Among them, according to the threaded holes on the back of the breaker, the adapter 20 is installed on the transverse groove at an appropriate height, and is horizontally moved on the transverse groove for adjustment. Then, the breaker and the adapter 20 are tightened on the bottom plate 10 by using the screw 30, and the engagement between the teeth on the bottom plate 10 and the adapter 20 is used to improve the connection firmness. Since the adapter 20 is installed according to the actual situation, there will be no waste, and the transverse grooves on the bottom plate 10 are also easy to process. Therefore, the structural cost can be effectively reduced.

[0028] Please refer to Figures 1-4 , mounting holes 40 are provided on the bottom plate 10. The mounting holes 40 are used to install the bottom plate 10 into a power distribution cabinet or other equipment, and multiple bottom plates 10 can also be spliced and used.

[0029] Please refer to Figures 1-4, the screw 30 is a ram's horn screw. The ram's horn screw facilitates manual screwing operation, enabling tool-free operation and simple operation.

[0030] Please refer to Figures 1-4 , the adapter 20 includes a T-shaped slider 21. A strip-shaped through groove is formed in the slider 21, and the screw 30 movably penetrates through the through groove. The slider 21 engages with the teeth on the edge of the transverse groove. The slider 21 drives the screw 30 to slide horizontally on the transverse groove, so as to adjust the position of the screw 30 according to the position of the threaded hole of the actual circuit breaker. When the screw 30 is tightened, the slider 21 engages with the teeth, and the position can be fixed and is not easy to loosen. Here, the teeth on the edge of the transverse groove mainly play a role in fixing the position and have low requirements for machining accuracy. The hobbing method can be used for machining, and the cost is low. The T-shaped slider 21 can be stuck into the transverse groove for sliding.

[0031] Please refer to Figures 1-4 , the adapter 20 further includes an adjusting block 22. A through hole is formed in the adjusting block 22, and the screw 30 movably penetrates through the through hole. The adjusting block 22 engages with the slider 21 in a tooth shape. The adjusting block 22 and the slider 21 are respectively located on both sides of the bottom plate 10, and the adjusting block 22 abuts against the external circuit breaker. The adjusting block 22 and the slider 21 are respectively placed on both sides of the bottom plate 10, so that the adjusting block 22 fits against the back of the circuit breaker. By adjusting the up and down of the adjusting block 22, the up and down position of the screw 30 is changed, so as to finely adjust the vertical height of the screw 30. When the screw 30 is tightened, the adjusting block 22 engages with the slider 21 and is stuck on the bottom plate 10 to realize the locking of the relative position. Such a setting can improve the matching degree between the screw 30 and the circuit breaker, and can also reduce the density of the transverse groove, further reducing the processing cost. It should be noted that if it is necessary to adjust the distance between the circuit breaker and the bottom plate 10, only a gasket needs to be sleeved on the screw 30. On the other hand, the height of the adjusting block 22 should be greater than the height of the transverse groove, so that when the adjusting block 22 is adjusted up and down, it can still be stuck on the transverse groove.

[0032] The working principle of the breaker support device is as follows: Place the adjusting block 22 and the slider 21 on both sides of the bottom plate 10 respectively, so that the adjusting block 22 fits against the back of the breaker. By adjusting the up and down position of the adjusting block 22, the up and down position of the screw 30 is changed, thereby finely adjusting the vertical height of the screw 30. After the screw 30 is tightened, the adjusting block 22 engages with the slider 21 to lock the relative position in the vertical direction. At the same time, the slider 21 also engages with the teeth on the bottom plate 10 to lock the relative position in the horizontal direction. Since the slider 21 and the adjusting block 22 can be separated, only the corresponding number of adapters 20 for the threaded holes of the breaker needs to be equipped, effectively reducing the structural cost. In summary, according to the threaded holes on the back of the breaker, the adapter 20 is installed on the horizontal groove at an appropriate height and laterally moved on the horizontal groove for adjustment. Then, the breaker and the adapter 20 are tightened on the bottom plate 10 using the screw 30, and the engagement between the teeth on the bottom plate 10 and the adapter 20 is used to improve the connection firmness. Since the adapter 20 is installed according to the actual situation, there will be no waste, and the horizontal groove on the bottom plate 10 is also easy to process, so the structural cost can be effectively reduced.
