Description

Technical Field

[0001] The invention belongs to the technical field of switches, and in particular relates to an opening and closing mechanism for side operation of switches. Background Art

[0002] Traditional switch operating mechanisms are installed on the front of the switch. For plug-and-play switch cabinets, switches with busbars installed on the side cannot be used normally. Generally, the door needs to be opened to use them, which makes use and maintenance inconvenient and has poor safety. Summary of the invention

[0003] In order to solve the above problems existing in the prior art, the present invention aims to provide an opening and closing mechanism which can open and close a plug-and-play switch in a cabinet from outside the cabinet.

[0004] The technical solution adopted by the present invention is:

[0005] A switch-on / off mechanism for side operation of a switch comprises an operating box fixed on a side column of a cabinet, an operating rod rotatably connected in the operating box, one end of the operating rod extending out of the cabinet, the other end of the operating rod connected to a gear rack mechanism, a push-pull plate connected to the output end of the gear rack mechanism, the other end of the push-pull plate connected to a toggle mechanism for toggling a switch handle, and the toggle mechanism sleeved on the switch handle. When the operating rod is rotated from outside the cabinet, the operating rod drives the gear rack mechanism to move, and the gear rack mechanism can push the push-pull plate to move linearly. The toggle mechanism is driven to move linearly during the movement of the push-pull plate. Since the toggle mechanism is sleeved on the switch handle, the toggle mechanism can toggle the switch handle of the plug-and-play switch when it moves. The operator can operate the plug-and-play switch in the cabinet without opening the cabinet, which simplifies the operation and ensures the timeliness of the switch opening and closing.

[0006] As a preferred embodiment of the present invention, the pull mechanism includes a limit frame, which is fixed on the switch, and a through slot is provided on the limit frame, from which the pull handle of the switch extends; a pull plate is sleeved in the limit frame, one end of the pull plate is connected to the push-pull plate, and the other end of the pull plate is provided with a square hole, and the pull handle of the switch is sleeved in the square hole. Since the pull handle of the switch is sleeved in the square hole of the pull plate, when the push-pull plate drives the pull plate to move, the edge of the square hole on the pull plate pushes the pull handle to achieve the opening or closing of the switch. The limit frame can limit the pull plate to ensure that the pull plate moves in a straight line, so that the pull plate can accurately pull the handle. The switch handle can extend from the through slot on the limit frame to avoid the situation where the limit frame blocks the pulling action.

[0007] As a preferred solution of the present invention, the middle section of the pull plate is bent. The middle section of the pull plate is bent twice at 90 degrees, so that the pull plate can compensate for the height difference between the push-pull plate and the limit frame, ensuring that the pull plate can be connected to the push-pull plate and the limit frame at the same time.

[0008] As a preferred embodiment of the present invention, the gear rack mechanism includes a gear and a moving frame, the gear is mounted on the operating rod, a row of rack holes is provided on the moving frame, the gear is meshed with the rack holes of the moving frame, and the moving frame is connected to the push-pull plate. When the operating rod is rotated, the operating rod drives the gear to rotate. The gear is meshed with a row of rack holes of the moving frame, and the gear can push the moving frame to move. When the moving frame moves, the push-pull plate and the pull mechanism move accordingly, so that the pull mechanism can open or close the switch.

[0009] As a preferred solution of the present invention, both sides of the operation box are provided with slide grooves, and both sides of the moving frame are provided with limiting edges, which are sleeved in the slide grooves. During the movement of the moving frame, the limiting edges on the moving frame always move in the slide grooves of the operation box, and the slide grooves limit the limiting edges, so that the moving frame can move in a straight line along an accurate path, ensuring the reliability of the transmission.

[0010] As a preferred solution of the present invention, a transverse long hole is provided at one end of the push-pull plate close to the pull mechanism, the transverse long hole is perpendicular to the push-pull plate, and the push-pull plate is connected to the pull mechanism through the transverse long hole; a connecting hole is provided at one end of the push-pull plate close to the gear rack structure, and the push-pull plate is connected to the gear rack mechanism through the connecting hole, and a longitudinal long hole is also provided on the push-pull plate, the longitudinal long hole is connected to the connecting hole, and the longitudinal long hole is parallel to the push-pull plate. When the push-pull plate needs to be removed during maintenance, the push-pull plate is pushed in a direction perpendicular to the push-pull plate, so that the connecting piece between the gear rack mechanism and the push-pull plate moves into the longitudinal long hole, so as to facilitate the removal of the push-pull plate.

[0011] The beneficial effects of the present invention are:

[0012] One end of the operating rod of the present invention extends out of the cabinet. When the operating rod is rotated from outside the cabinet, the operating rod drives the rack and pinion mechanism to move, and the rack and pinion mechanism can push the push-pull plate to move linearly. During the movement of the push-pull plate, the pull mechanism is driven to move linearly. Since the pull mechanism is sleeved on the handle of the switch, the pull mechanism can pull the handle of the plug-and-play switch when it moves. The operator can operate the plug-and-play switch in the cabinet without opening the cabinet, which simplifies the operation and ensures the timeliness of opening and closing the switch.

DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] like Figure 1 to Figure 3 As shown, the opening and closing mechanism for side operation of the switch of this embodiment includes an operating box 1 fixed on the side column of the cabinet 6, an operating rod 2 is rotatably connected inside the operating box 1, one end of the operating rod 2 extends out of the cabinet 6, and the other end of the operating rod 2 is connected to a gear rack mechanism 3, the output end of the gear rack mechanism 3 is connected to a push-pull plate 4, and the other end of the push-pull plate 4 is connected to a pulling mechanism 5 for pulling the handle of the switch 7, and the pulling mechanism 5 is sleeved on the handle of the switch 7.

[0022] The operating rod 2 includes a square rod section and a round rod section. The square rod section is sleeved with a round sleeve, and the round sleeve is sleeved in the upper round hole of the operating box 1. The round rod section is provided with a square hole, and the lower end of the square rod section is inserted into the square hole and locked by a screw. The round rod section is sleeved in the lower round hole of the operating box 1 and has a limiting step.

[0023] When the operating lever 2 is rotated from outside the cabinet 6, the operating lever 2 drives the rack and pinion mechanism 3 to move, and the rack and pinion mechanism 3 can push the push-pull plate 4 to move linearly. The push-pull plate 4 drives the pull mechanism 5 to move linearly during its movement. Since the pull mechanism 5 is sleeved on the handle of the switch 7, the pull mechanism 5 can pull the handle of the plug-and-play switch 7 when it moves. The operator can operate the plug-and-play switch 7 in the cabinet 6 without opening the cabinet 6, which simplifies the operation and ensures the timeliness of opening and closing the switch 7.

[0024] Specifically, Figure 4As shown, the pull mechanism 5 includes a limit frame 51, which is fixed on the switch 7, and a through slot 511 is provided on the limit frame 51, and the pull handle of the switch 7 extends from the through slot 511; a pull plate 52 is sleeved in the limit frame 51, one end of the pull plate 52 is connected to the push-pull plate 4, and the other end of the pull plate 52 is provided with a square hole 521, and the pull handle of the switch 7 is sleeved in the square hole 521. Since the pull handle of the switch 7 is sleeved in the square hole 521 of the pull plate 52, when the push-pull plate 4 drives the pull plate 52 to move, the edge of the square hole 521 on the pull plate 52 pushes the pull handle to achieve the opening or closing of the switch 7. The limit frame 51 can limit the pull plate 52 to ensure that the pull plate 52 moves in a straight line, so that the pull plate 52 can accurately pull the pull handle. The pull handle of the switch 7 can extend from the through slot 511 on the limit frame 51 to avoid the situation where the limit frame 51 blocks the pull action. The middle section of the pull plate 52 is bent. The middle section of the pull plate 52 is bent twice at 90 degrees, so that the pull plate can compensate for the height difference between the push-pull plate 4 and the limit frame 51, ensuring that the pull plate 52 can be connected to the push-pull plate 4 and the limit frame 51 at the same time.

[0025] Specifically, Figure 5 and Figure 6 As shown, the gear rack mechanism 3 includes a gear 31 and a moving frame 32. The gear 31 is mounted on the operating rod 2. The moving frame 32 is provided with a row of rack holes 321. The gear 31 meshes with the rack holes 321 of the moving frame 32. The moving frame 32 is connected to the push-pull plate 4. When the operating rod 2 is rotated, the operating rod 2 drives the gear 31 to rotate. The gear 31 meshes with a row of rack holes 321 of the moving frame 32, and the gear 31 can push the moving frame 32 to move. When the moving frame 32 moves, the push-pull plate 4 and the pulling mechanism 5 move accordingly, so that the pulling mechanism 5 can open or close the switch 7.

[0026] In order to ensure the stability of the moving frame 32 during movement, the operation box 1 is provided with a slide groove 11 on both sides, and a limiting edge 322 is provided on both sides of the moving frame 32, and the limiting edge 322 is sleeved in the slide groove 11. During the movement of the moving frame 32, the limiting edge 322 on the moving frame 32 always moves in the slide groove 11 of the operation box 1, and the slide groove 11 limits the limiting edge 322, so that the moving frame 32 can move in a straight line along an accurate path, ensuring the reliability of the transmission.

[0027] In order to facilitate the disassembly of the push-pull plate 4, a transverse long hole 41 is provided at one end of the push-pull plate 4 close to the pull mechanism 5, and the transverse long hole 41 is perpendicular to the push-pull plate 4, and the push-pull plate 4 is connected to the pull mechanism 5 through the transverse long hole 41; a connecting hole 42 is provided at one end of the push-pull plate 4 close to the gear rack structure 31, and the push-pull plate 4 is connected to the gear rack mechanism 3 through the connecting hole 42. A longitudinal long hole 43 is also provided on the push-pull plate 4, and the longitudinal long hole 43 is connected to the connecting hole 42, and the longitudinal long hole 43 is parallel to the push-pull plate 4. The diameter of a section of the longitudinal long hole 43 close to the connecting hole 42 is larger than the diameter of the connecting hole 42. When the push-pull plate 4 needs to be removed during maintenance, the push-pull plate 4 is pushed in a direction perpendicular to the push-pull plate 4, so that the connecting piece between the gear rack mechanism 3 and the push-pull plate 4 moves into the longitudinal long hole 43, so that the push-pull plate 4 can be easily removed.

[0028] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
