Description

Technical Field

[0001] This utility model relates to the technical field of changeover switch mounting bases, and in particular to a mounting base for an automatic changeover switch. Background Technology

[0002] An automatic power transfer switch (hereinafter referred to as a transfer switch) is an electrical appliance consisting of one or more transfer switching devices and other necessary electrical components. It is used to detect power circuits and automatically transfer one or more load circuits from one power source to another. It is a high-performance, safe, reliable, highly automated, and widely applicable dual-power automatic transfer switch.

[0003] Currently, mounting bases and automatic transfer switches are mostly fixed with bolts. For example, the mounting base structure of a dual-power automatic transfer switch disclosed in Chinese Patent Publication No. CN207021167U is shown. However, since there are many bolts used to fix the rotary switch, and tools are required to tighten or loosen the bolts, it is quite troublesome to disassemble and assemble the mounting base and the automatic transfer switch, making it inconvenient for maintenance personnel to disassemble and assemble the automatic transfer switch on the mounting base. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, such as: at present, the mounting base and the automatic transfer switch are mostly fixed by bolts. However, since there are many bolts used to fix the rotating switch, and tools are required to tighten or loosen the bolts, it is difficult to disassemble and assemble the mounting base and the automatic transfer switch. This makes it inconvenient for maintenance personnel to disassemble and assemble the automatic transfer switch on the mounting base. Therefore, a mounting base for automatic transfer switches is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic transfer switch mounting base includes a mounting plate, a housing fixedly connected to the upper surface of the mounting plate, a switch body disposed on the upper surface of the housing, mounting brackets fixedly connected to the left and right sides of the switch body, mounting holes formed inside the mounting brackets, a circular hole formed on the upper surface of the housing, a cylinder fixedly connected to the inner wall of the circular hole, the surface of the cylinder contacting the inner wall of the mounting hole, U-shaped plates fixedly connected to the left and right sides of the inner wall of the cylinder, sliding holes formed on the left and right sides of the cylinder, locking brackets fitted to the inner walls of the sliding holes, the inner walls of the U-shaped plates, the upper surface of the mounting brackets, and the upper surface of the mounting plate, a sliding groove formed at the bottom of the housing, a reset bracket fitted to the upper surface of the mounting plate, the inner wall of the sliding groove, and the surface of the locking bracket, the front and rear sides of the reset bracket fixedly connected to the inner wall of the housing.

[0007] Preferably, the locking bracket includes a square column, the surface of which contacts the inner wall of the U-shaped plate, a cylindrical column is fixedly connected to the bottom of the square column, the inner wall of the reset bracket and the upper surface of the mounting plate are both in contact with the surface of the cylindrical column, a trapezoidal block is fixedly connected to the side of the square column, and the inner wall of the sliding hole and the upper surface of the mounting bracket are both in contact with the surface of the trapezoidal block.

[0008] Preferably, the reset bracket includes a sliding plate, the inner wall of the slide groove and the upper surface of the mounting plate are in contact with the surface of the sliding plate, a V-shaped hole is provided inside the sliding plate, the inner wall of the V-shaped hole is in contact with the surface of the cylinder, hollow blocks are fixedly connected to the left and right sides of the sliding plate, and springs are fixedly connected to the inner wall of the hollow blocks and the front and rear sides of the inner wall of the box.

[0009] Preferably, the slide plate has a through hole inside, and a magnetic block is fixedly connected to the inner wall of the through hole. Iron rings are fitted to the front of the box, the upper surface of the magnetic block, and the inner wall of the through hole.

[0010] Preferably, a U-shaped post is fixedly connected to the upper surface of the iron ring.

[0011] Preferably, a first connecting block is fixedly connected to the front of the box body, an elastic rope is adhered to the inner wall of the first connecting block, a second connecting block is adhered to one end of the elastic rope, and the inner wall of the second connecting block is fixedly connected to the surface of the U-shaped column.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model comprises a mounting plate, a housing, a circular hole, a cylinder, a U-shaped plate, a sliding hole, a locking bracket, a sliding groove, and a reset bracket. When the switch body is placed on the housing, the reset bracket causes the trapezoidal block on the locking bracket to contact the mounting bracket. The interaction between the trapezoidal block and the mounting bracket secures the switch body to the mounting base. When the user pushes the sliding plate on the reset bracket, the V-shaped hole and cylinder work together to separate the trapezoidal block from the mounting bracket, allowing the switch body to be removed directly from the housing. Furthermore, the combination of the mounting plate, housing, circular hole, cylinder, U-shaped plate, sliding hole, locking bracket, sliding groove, and reset bracket allows the user to easily assemble and disassemble the switch body on the mounting base by pushing or pulling the sliding plate on the reset bracket, making the mounting base more convenient to use.

[0014] This invention incorporates a through hole, a magnetic block, and an iron ring. When the iron ring is inserted into the through hole, the magnetic block attracts the iron ring, fixing it within the hole. The interaction between the iron ring and the through hole prevents the sliding plate from moving. Furthermore, after the switch body is fixed to the mounting base, the trapezoidal block is locked in place by the interaction of the through hole, the magnetic block, and the iron ring, thus making the connection between the switch body and the mounting base more secure.

[0028] Example 1

[0029] Reference Figure 1-10 An automatic transfer switch mounting base includes a mounting plate 1, a housing 2 fixedly connected to the upper surface of the mounting plate 1, a switch body 3 disposed on the upper surface of the housing 2, mounting brackets 4 fixedly connected to the left and right sides of the switch body 3, mounting holes 5 opened inside the mounting brackets 4, a circular hole 6 opened on the upper surface of the housing 2, a cylinder 7 fixedly connected to the inner wall of the circular hole 6, the surface of the cylinder 7 contacting the inner wall of the mounting hole 5, U-shaped plates 8 fixedly connected to the left and right sides of the inner wall of the cylinder 7, sliding holes 9 opened on the left and right sides of the cylinder 7, locking brackets 10 fitted together on the inner wall of the sliding holes 9, the inner wall of the U-shaped plates 8, the upper surface of the mounting brackets 4 and the upper surface of the mounting plate 1, a sliding groove 11 opened at the bottom of the housing 2, a reset bracket 12 fitted together on the upper surface of the mounting plate 1, the inner wall of the sliding groove 11 and the surface of the locking bracket 10, and the front and rear sides of the reset bracket 12 fixedly connected to the inner wall of the housing 2.

[0030] The locking bracket 10 includes a square column 101, the surface of which contacts the inner wall of the U-shaped plate 8. A cylindrical column 102 is fixedly connected to the bottom of the square column 101. The inner wall of the reset bracket 12 and the upper surface of the mounting plate 1 are both in contact with the surface of the cylindrical column 102. A trapezoidal block 103 is fixedly connected to the side of the square column 101. The inner wall of the sliding hole 9 and the upper surface of the mounting bracket 4 are both in contact with the surface of the trapezoidal block 103. When the trapezoidal block 103 contacts the mounting bracket 4, the switch body 3 is fixed to the box 2 through the cooperation of the trapezoidal block 103 and the mounting bracket 4. When the trapezoidal block 103 is separated from the mounting bracket 4, the switch body 3 can be directly removed from the box 2. When the mounting bracket 4 is fitted onto the cylinder 7 and the trapezoidal block 103 is pressed down, the distance between the two trapezoidal blocks 103 on the left and right can be reduced through the inclined surface on the trapezoidal block 103.

[0031] The reset bracket 12 includes a slide plate 121. The inner wall of the slide groove 11 and the upper surface of the mounting plate 1 are in contact with the surface of the slide plate 121. A V-shaped hole 122 is opened inside the slide plate 121. The inner wall of the V-shaped hole 122 is in contact with the surface of the cylinder 102. Hollow blocks 123 are fixedly connected to both the left and right sides of the slide plate 121. Springs 124 are fixedly connected to the inner wall of the hollow blocks 123 and the front and rear sides of the inner wall of the box 2. When the slide plate 121 is pushed, the distance between the two trapezoidal blocks 103 on the left and right sides decreases through the cooperation of the V-shaped hole 122 and the cylinder 102. When the slide plate 121 is released, the slide plate 121 returns to the initial position through the spring 124, and the distance between the two trapezoidal blocks 103 on the left and right sides increases through the cooperation of the V-shaped hole 122 and the cylinder 102.

[0032] Example 2

[0033] Reference Figure 1-10 The slide plate 121 has a through hole 13 inside. A magnetic block 14 is fixedly connected to the inner wall of the through hole 13. Iron rings 15 are attached to the front of the box body 2, the upper surface of the magnetic block 14, and the inner wall of the through hole 13. When the iron ring 15 is inserted into the through hole 13, the magnetic block 14 attracts the iron ring 15, fixing the iron ring 15 in the through hole 13. The cooperation between the iron ring 15 and the through hole 13 prevents the slide plate 121 from being pushed. After the switch body 3 is fixed on the mounting base, the trapezoidal block 103 can be locked by the cooperation of the through hole 13, the magnetic block 14, and the iron ring 15, making the switch body 3 more firmly fixed to the mounting base.

[0034] Example 3

[0035] Reference Figure 1-10 A U-shaped post 16 is fixedly connected to the upper surface of the iron ring 15. The U-shaped post 16 makes it easier for the user to remove the iron ring 15 from the through hole 13. A first connecting block 17 is fixedly connected to the front of the box body 2. An elastic rope 18 is glued to the inner wall of the first connecting block 17. A second connecting block 19 is glued to one end of the elastic rope 18. The inner wall of the second connecting block 19 is fixedly connected to the surface of the U-shaped post 16. Through the cooperation of the first connecting block 17, the elastic rope and the second connecting block 19, the U-shaped post 16 is connected to the box body 2, so that the iron ring 15 is not easily lost after being separated from the through hole 13.

[0036] In this utility model, when using the mounting base, the user first fixes the mounting plate 1 on the mounting base at the designated position. Then, the iron ring 15 is removed from the through hole 13, and the mounting bracket 4 on the switch body 3 is placed inside the cylinder 7. At this time, by pressing down on the switch body 3, the mounting bracket 4 presses against the inclined surface of the trapezoidal block 103, reducing the distance between the two trapezoidal blocks 103. Simultaneously, through the cooperation of the V-shaped hole 122 and the cylinder 102, the sliding plate 121 moves, and the spring 124 deforms. When the switch body 3 contacts the housing 2, the elastic force of the spring 124 causes the sliding plate 121 to return to its initial position. Furthermore, through the cooperation of the V-shaped hole 122 and the cylinder 102, the trapezoidal block 103 and the mounting bracket 4... When the upper surface contacts the mounting bracket 4, the switch body 3 is fixed to the box 2 by the cooperation of the trapezoidal block 103 and the mounting bracket 4. Then, the iron ring 15 is inserted into the through hole 13. The iron ring 15 is fixed in the through hole 13 by the attraction of the magnetic block 14. The cooperation between the iron ring 15 and the through hole 13 prevents the slide plate 121 from being pushed. At this time, the trapezoidal block 103 can be locked. When the user needs to remove the switch body 3 from the mounting bracket, first remove the iron ring 15 from the through hole 13. Then, by pushing the slide plate 121, the trapezoidal block 103 is separated from the mounting bracket 4 by the cooperation of the V-shaped hole 122 and the cylinder 102. After the mounting bracket 4 is separated from the trapezoidal block 103, the switch body 3 can be directly separated from the box 2.
