[0002] In the field of circuit breakers, existing technology typically uses a method of directly fixing the circuit breaker to the upper-level equipment for installation. Although this installation method ensures the stability of the equipment, due to the circuit breaker's large size and complex installation environment (such as limited space in the distribution box or high temperature and high humidity conditions), the maintenance and disassembly process requires multiple steps, including disconnecting the power supply, removing the fixing bolts, and cleaning the contact points. Summary of the Invention

[0003] The purpose of the present invention is to provide a rotating push-pull locking structure to address the above-mentioned shortcomings. This structure can not only fix the equipment on the frame through a drawer, but also enable the drawer to drive the equipment out, thereby facilitating equipment maintenance and repair, and meeting the requirements of equipment installation stability and maintainability.

[0004] The present invention is achieved through the following solutions:

[0005] A rotating push-pull structure and a method of using the same, comprising a base plate, a slide rail, a support frame, a rotating rod, a rotating rod groove, a locking rod, a retaining nut and a pad with a threaded hole; the base plate is detachably connected to the slide rail, the rotating rod groove is fixed to the base plate, the rotating rod is rotatably arranged in the rotating rod groove, the rear end of the rotating rod can be embedded in the pad with a threaded hole for relative fixation, the locking rod is arranged through the support frame, the end of the locking rod is provided with a threaded section, the end of the locking rod can be arranged in the pad with a threaded hole, the retaining nut is sleeved on the locking rod, and the pad with a threaded hole is fixed to the base plate.

[0006] Based on the above-mentioned rotating push-pull structure, the mounting and fixing holes of the bottom plate correspond to the positions of the holes of the slide rail.

[0007] Based on the above-mentioned rotating push-pull structure, the bottom and sides of the rotating rod are arc-shaped, and the top is flat. When the drawer is fixed, the top plane faces upward. When the drawer moves, the rotating rod rotates 90° to support the slide rail.

[0008] Based on the above-mentioned rotating push-pull structure, the support frame is connected to the equipment in the drawer device, and there is a hole on the support frame; the support frame is connected to the equipment in the drawer device, and there is a hole on the support frame.

[0009] Based on the above-mentioned rotating push-pull structure, the rotating rod groove is fixed on the bottom plate; the rotating rod is placed on the rotating rod groove support block; the front and rear ends of the rotating rod are threaded, and the rotating rod can be fixed to the pad with threaded holes through the threads.

[0010] Based on the above-mentioned rotating push-pull structure, the locking rod is set through the limiting hole of the support frame, and the rear end of the locking rod has an external thread. The locking rod can be fixed on the pad with threaded holes through the external thread; there are retaining nuts at both ends of the locking rod.

[0011] Based on the above-mentioned rotating push-pull structure, the backing plate with threaded holes is provided with side threaded holes matched with the rotating rod and a central threaded hole matched with the locking rod.

[0012] Based on the above-mentioned rotating push-pull structure, support bars cooperating with the slide rails are provided on both sides of the bottom plate.

[0013] Based on the above-mentioned rotating push-pull structure, the slide rail includes a first contact surface and a second contact surface, the first contact surface and the second contact surface are arranged in a stepped manner, the first contact surface contacts the side wall of the rotating rod, and the second contact surface contacts the support bar.

[0014] The present invention also discloses a method for using a push-pull locking structure, wherein when the drawer is in a fixed position, the tail of the locking rod is located in a pad with a threaded hole, the direction of the rotating rod is horizontally upward, and the slide rail is fixed to the bottom plate by a stud; when starting to pull out the drawer, first remove the screws between the slide rail and the bottom plate, then twist the locking rod to make the tail of the locking rod disengage from the threaded pad with a hole, drive the support frame and the equipment to be pulled out together, and then rotate the rotating rods on both sides 90° to lift the slide rail, so that the surface contact between the slide rail and the bottom plate is changed to line contact, reducing the contact area between the slide rail and the bottom plate, thereby reducing the friction during the pulling process; when returning the drawer to its original position, twist the locking rod to drive the equipment to complete the return through the support frame, the locking rod and the drawer are locked, and finally the slide rail is fixed to the bottom plate.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. Through structural design, this solution allows the equipment to be fixed to the frame through a drawer, and at the same time, the drawer can be used to pull out the equipment, which facilitates equipment maintenance and repair, while meeting the requirements of equipment installation stability and maintainability.

[0017] 2. During conventional support, when the rotating rod is rotated, its flat end contacts the first contact surface, so that during normal operation, the components on it have a larger contact area with the bottom, ensuring overall stability. When movement is required, the rotating rod is rotated so that the arcuate surface contacts the first contact surface. At the same time, the track can be lifted to a certain height so that the second contact surface is spaced a certain distance from the support bar. At this time, it is only supported by the rotating rod. Since the end of the rotating rod is fixed to the pad 8 with threaded holes through threads, the gravity on it cannot make it rotate further. At this time, the contact surface between the track and the bottom is only the contact area between the arcuate surface and the first contact surface, which greatly reduces the friction and facilitates the sliding of the devices thereon.

[0028] Example 1

[0029] like Figures 1 to 5 As shown, the present invention provides a technical solution:

[0030] When the drawer is moved, the top end of the drawer 1 is rotated 90 degrees to support the drawer 2, thereby reducing the friction between the drawer 2 and the bottom plate 1 and reducing the force of pulling the drawer out.

[0031] Furthermore, the support frame 3 is connected to the equipment in the drawer device, and there is an assembly hole on the support frame 3.

[0032] Furthermore, the rotating rod slot 5 is fixed on the base plate 1 .

[0033] Furthermore, the rotating rod 4 is rotatably disposed in the rotating rod slot 5 .

[0034] Furthermore, both the front and rear ends of the rotating rod 4 are provided with threads. After the drawer is pushed in, the rotating rod can be fixed on the backing plate 8 with threaded holes through the threads.

[0035] Furthermore, the locking rod 6 passes through the limiting hole of the support frame 3 and has a thread at the rear end, and can be fixed on the backing plate 8 with a threaded hole.

[0036] Furthermore, both ends of the locking rod 6 are provided with retaining nuts 7 .

[0037] The threaded plate is provided with a side threaded hole 81 that cooperates with the rotating rod and a center threaded hole 82 that cooperates with the locking rod.

[0038] Support bars 9 cooperating with the slide rail are provided on both sides of the bottom plate; the slide rail can include a first contact surface 21 and a second contact surface 22, the first contact surface and the second contact surface are arranged in a stepped manner, the first contact surface contacts the side wall of the rotating rod, and the second contact surface contacts the support bar.

[0039] Based on the above structure, during conventional support, when the rotating rod is rotated, its flat end contacts the first contact surface, so that during normal operation, the components on it have a larger contact area with the bottom, ensuring overall stability. When movement is required, the rotating rod is rotated so that the arcuate surface contacts the first contact surface. At the same time, the track can be lifted to a certain height so that the second contact surface is separated from the support bar by a certain distance. At this time, it is only supported by the rotating rod. Since the end of the rotating rod is fixed to the threaded hole pad 8 by threads, the gravity on it cannot cause it to rotate further. At this time, the contact surface between the track and the bottom is only the contact area between the arcuate surface and the first contact surface, which greatly reduces the friction and facilitates the sliding of the devices thereon.

[0040] Reference Figure 4 As shown, when the drawer is placed, the tail of the locking rod 6 is located in the pad 8 with threaded holes, the direction of the rotating rod 4 is horizontally upward, and the slide rail 2 is fixed to the bottom plate 1 by studs.

[0041] Reference Figure 2 As shown, when starting to pull out the drawer, first remove the studs between the slide rail 2 and the bottom plate 1, then move the locking rod 6 to disengage the tail end of the locking rod 6 from the threaded pad 8 with holes, and pull out the support frame 3 and the equipment together, then rotate the rotating rods on both sides 90° to lift the slide rail, reduce the contact area between the slide rail and the bottom plate, and thus reduce the friction during the pulling process.

[0042] Example 2

[0043] Based on the above embodiment 1, this embodiment provides a method for using a rotating push-pull locking structure;

[0044] When the drawer is in a fixed position, the tail of the locking rod is located in the pad with threaded holes, the direction of the rotating rod is horizontal and upward, and the slide rail is fixed to the bottom plate by studs; when starting to pull out the drawer, first remove the screws between the slide rail and the bottom plate, then turn the locking rod to make the tail of the locking rod disengage from the threaded pad with holes, drive the support frame and the equipment to be pulled out together, then rotate the rotating rods on both sides 90°, lift the slide rail, and change the surface contact between the slide rail and the bottom plate to line contact, reducing the contact area between the slide rail and the bottom plate, thereby reducing the friction during the pulling process; when returning the drawer to its original position, twist the locking rod to drive the equipment to complete the return through the support frame, the locking rod and the drawer are locked, and finally the slide rail is fixed to the bottom plate.
