[0024] like Figures 1 to 4 As shown, an installation device 1 of this utility model includes an installation bracket 11 and a connecting bracket 12. The installation bracket 11 includes a first support plate 111, a first connecting plate 112, and a second connecting plate 113. The first support plate 111 is used to connect to the circuit breaker body 2. The first support plate 111 has a first installation hole 1111 that runs vertically through it. The second connecting plate 113 is spaced below the first support plate 111. The two ends of the first connecting plate 112 are respectively connected to the first support plate 111 and the second connecting plate 113. The connecting bracket 12 is disposed on the bottom surface of the second connecting plate 113 and is detachably connected to the second connecting plate 113. The top surface of the connecting bracket 12 has a second installation hole 125 corresponding to the first installation hole 1111.
[0025] In the above technical solution, the mounting bracket 11 is used to connect to the circuit breaker body 2, and the connecting bracket 12 is used to connect to the mounting base 13 installed on the distribution cabinet. The mounting bracket 11 and the connecting bracket 12 are detachably connected. Specifically, in the mounting bracket 11, the first support plate 111 is used to connect to the circuit breaker body 2, and the second connecting plate 113 is spaced below the first support plate 111. The first connecting plate 112 is connected to the first support plate 111 and the second connecting plate 113. The second connecting plate 113 is located on the top surface of the mounting bracket 11 and is detachably connected to the mounting bracket 11. The top surface of the first support plate 111 has a first mounting hole 1111 that penetrates vertically. The top surface of the circuit breaker 2 is provided with a second mounting hole 125 corresponding to the first mounting hole 1111. This allows the operator to insert a long rod-shaped tool through the first mounting hole 1111 and into the second mounting hole 125. By using the long rod-shaped tool to abut against the first mounting hole 1111 and the second mounting hole 125, the operator can pry the mounting bracket 11 towards the busbar and away from the busbar, so that the clamping device 3 on the circuit breaker body 2 is clamped to or detached from the phase busbar. In summary, the installation device 1 of this utility model allows the operator to easily move the circuit breaker body 2 towards the busbar and away from the busbar, making the circuit breaker installation and removal work very easy and simple, and eliminating the original safety hazards.
[0026] Furthermore, the two ends of the first connecting plate 112 are respectively connected to the side of the first support plate 111 relative to the second direction and the side of the second connecting plate 113 relative to the second direction, and the second connecting plate 113 protrudes from the first connecting plate 112 along the second direction.
[0027] Furthermore, the connecting bracket 12 includes a third connecting plate 121 and two side brackets 122. The third connecting plate 121 is detachably connected to the second connecting plate 113. The second mounting hole 125 is provided on the top surface of the third connecting plate 121. The two side brackets 122 are respectively provided on both sides of the third connecting plate 121 along the first direction. The side brackets 122 are connected to the third connecting plate 121. The two side brackets 122 are used to provide other features to increase the expandability of the mounting device 1. The second connecting plate 113 protrudes from the side of the first support plate 111 relative to the second direction to facilitate the disassembly and assembly of the connecting parts between the second connecting plate 113 and the third connecting plate 121 by the operator.
[0028] Furthermore, the top surface of the side frame 122 is provided with a second support plate 123, the top surface of the second support plate 123 is flush with the top surface of the first support plate 111, and the second support plate 123 is used to abut against the bottom surface of the circuit breaker body 2 to increase the area supporting the circuit breaker body 2, thereby increasing the stability of the circuit breaker body 2.
[0029] Furthermore, the side frame 122 is fixedly provided with a first abutment plate 124 on the side of the connecting bracket 12, and a second abutment plate 14 is provided directly below the first abutment plate 124. The second abutment plate 14 is fixedly connected to the mounting bracket 11. The second abutment plate 14 restricts the movement of the connecting bracket 12 in the vertical direction, preventing the circuit breaker body 2 from tilting in the vertical direction before the mounting bracket 11 is connected to the connecting bracket 12, thereby facilitating the installation and removal of the circuit breaker. Preferably, the second abutment plate 14 is provided on the bottom surface of the first abutment plate 124.
[0030] Furthermore, the top of the end of the second abutment plate 14 away from the second connecting plate 113 is provided with a guide chamfer 141. When the mounting bracket 11 is to be connected to the connecting bracket 12, the first abutment plate 124 and the guide chamfer 141 abut against each other, which makes it easier and more convenient for the mounting bracket 11 to be pushed into the connecting bracket 12.
[0031] Furthermore, it also includes connecting bolts. The second connecting plate 113 is provided with a first connecting hole 1131 that extends vertically through to the side of the second connecting plate 113 away from the first support plate 111. The top surface of the third connecting plate 121 is provided with a second connecting hole 1211 that extends vertically through. The connecting bolt passes through the first connecting hole 1131 and the second connecting hole 1211 to connect the second connecting plate 113 and the third connecting plate 121. By making the first connecting hole 1131 an elongated hole extending along the direction of pushing in and pulling out the circuit breaker body 2, the fault tolerance rate of pushing in and pulling out the circuit breaker body 2 is improved, and the situation where the first mounting hole 1111 and the second mounting hole 125 cannot correspond after being pried is prevented.
[0032] Furthermore, it also includes a mounting base 13, a plurality of mounting brackets 11 and a plurality of connecting brackets 12. The mounting base 13 extends along a first direction, and the plurality of connecting brackets 12 are spaced apart along the first direction on the top surface of the mounting base 13. The mounting brackets 11 are arranged one-to-one with the connecting brackets 12. The mounting base 13 is fixedly connected to the power distribution cabinet.
[0033] Furthermore, both the first mounting hole 1111 and the second mounting hole 125 are rectangular holes to increase the contact area of the long rod-shaped tool, thereby reducing the damage caused by repeated contact with the first mounting hole 1111 and the second mounting hole 125.
[0034] Furthermore, the top surface of the connecting bracket 12 is provided with a plurality of second mounting holes 125 spaced apart along the second direction, so that the operator can select the second mounting hole 125 for easy insertion for operation.
[0035] This utility model also relates to a circuit breaker, including a circuit breaker body 2 and the aforementioned mounting device 1, wherein the circuit breaker body 2 is fixedly mounted on the top surface of the first support plate 111; further, the circuit breaker is provided with three clamps 3 spaced apart along the vertical direction.
[0036] Furthermore, the clamping device 3 includes two clamping jaws arranged opposite each other in a vertical direction. Each clamping jaw has a clamping portion, and a clamping gap is formed between the clamping portions of the two clamping jaws. One end of each clamping jaw is connected to the circuit breaker body 2, and the other end has a guide surface relative to the surface of the other clamping jaw. The distance between the guide surfaces of the two clamping jaws gradually decreases from away from the circuit breaker body 2 to close to the circuit breaker body 2. The guide surfaces are in contact with the clamping portion to facilitate the clamping device 3 to clamp the phase row when the circuit breaker assembly is pushed in and to disengage from the phase row when the circuit breaker assembly is removed.
[0037] Furthermore, the specific connection methods of fixed setting and fixed connection refer to the methods that can fix the relative positional relationship of two connected components, including fixing by connectors, fixing by welding, fixing by adhesive, fixing by integral molding, and fixing by snap-fit connection.
[0038] Furthermore, the specific connection method of detachable connection refers to the fact that the two connected parts can be repeatedly disassembled and assembled without damage or serious deformation, including fixing by connectors and fixing by snap-fit connection.
[0039] Furthermore, the connectors include fasteners, straps, ropes, pneumatic connectors, hydraulic connectors, flanges, Velcro, and buttons.
