Description

Technical Field

[0001] This invention relates to the field of switch auxiliary equipment technology, and in particular to an air switch latch to prevent misoperation. Background Technology

[0002] During substation equipment maintenance, it is often necessary to perform opening and closing operations on equipment such as switches and disconnectors. If maintenance work is carried out without effective isolation and reminder measures for the maintenance isolation surface equipment, serious misoperation incidents can easily occur. For example, energizing with the grounding switch on can lead to damage to power equipment, endanger the safety of the power grid, and even cause injury or death to operators. Therefore, it is necessary to isolate and lock the maintenance equipment, and to take safety measures such as tagging or padding the control power supply and motor power air switches of the de-energized equipment and maintenance isolation surface equipment.

[0003] Currently, there are two common practices for implementing safety measures for circuit breakers: one is to print warnings such as "Do not close the circuit, people are working" or "Do not close the circuit, people are working on the line" on labels; the other is to use snap-on signs of the same size. However, these methods are not reusable, are not environmentally friendly, require constant purchase of labels, and the adhesive properties of the tape will significantly decrease with changes in the external environment. For example, high temperatures and rain can reduce the adhesiveness of the tape, making it easy for warning signs to fall off, which could lead to workers accidentally closing the circuit breaker and potentially threatening equipment, the power grid, and personal safety.

[0042] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] In the description of the embodiments of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0045] For easier understanding, please refer to Figure 1 The present invention provides an air switch latch to prevent misoperation, comprising: an air switch body 1, the air switch body 1 being provided with a toggle piece, and further comprising: a mounting component and a locking component;

[0046] Among them, the toggle piece is the knife switch piece of the air switch body 1.

[0047] The mounting component is detachably mounted on the air switch body 1. The mounting component has a horizontal extension block 21 and a vertical mounting block 22. The horizontal extension block 21 and the vertical mounting block 22 are connected to form an L-shaped structure. The horizontal extension block 21 is set perpendicular to the air switch body 1.

[0048] The installation height of the mounting component relative to the air switch body 1 is set based on actual needs, generally corresponding to the position of the toggle switch at the bottom. The horizontal extension block 21 is set perpendicular to the length direction of the air switch body 1. The horizontal extension block 21 and the vertical mounting block 22 are perpendicular to each other. The connection between the horizontal extension block 21 and the vertical mounting block 22 makes the cross-sectional structure of the mounting component L-shaped.

[0049] like Figure 2 As shown, the locking assembly includes a locking block 8 and a fixing block 13. The locking block 8 and the fixing block 13 cooperate to form a locking space, which is used to lock the position of the toggle piece.

[0050] The horizontal extension block 21 has a sliding through hole 7 along the axial direction that is adapted to the structure of the locking block 8, and the locking block 8 is slidably connected in the sliding through hole 7;

[0051] Limiting plates are provided on both sides of the inner wall of the sliding through hole 7, and connecting plates 9 are provided on both sides of the locking block 8. The connecting plates 9 and the limiting plates are fixedly connected by the first reset spring 10. The locking block 8 moves up and down in the sliding through hole 7 under the action of the first reset spring 10.

[0052] In the natural state of the first return spring 10, the locking block 8 is located outside the sliding through hole 7 and protrudes above the horizontal extension block 21. In the compressed state of the first return spring 10, the locking block 8 is located inside the sliding through hole 7. Specifically, when the locking block 8 slides outward, it will cause the connecting plate 9 to squeeze the first return spring 10. After the squeezing force is lost, the first return spring 10 will lock the locking block 8 back to its original position, thereby improving the convenience of use.

[0053] like Figure 3 As shown, a limiting groove 12 is formed along the depth direction on the surface of the vertical mounting block 22 facing the outer side of the air switch body 1. The opening direction of the limiting groove 12 is set towards the outer side of the air switch body 1. The fixing block 13 is disposed in the limiting groove 12. The fixing block 13 is fixedly connected to the bottom of the limiting groove 12 by the second return spring 14. The fixing block 13 moves within the limiting groove 12 under the action of the second return spring 14.

[0054] When the second return spring 14 is in its natural state, the fixing block 13 is located outside the limiting groove 12 and protrudes from the vertical mounting block 22. When the second return spring 14 is in its compressed state, the fixing block 13 is located inside the limiting groove 12.

[0055] In order to more effectively lock the position of the toggle switch, multiple limiting grooves 12 and fixing blocks 13 can be provided. Multiple limiting grooves 12 and fixing blocks 13 are evenly arranged on the vertical mounting block 22, which can fix multiple switches at the same time, reduce the use of locking devices, and improve the efficiency of use.

[0056] It should be noted that the working process of this embodiment is as follows:

[0057] According to actual needs, the toggle piece on the air switch body 1 is pulled down, and then the toggle piece presses the locking block 8 under the action of the first return spring 10, so that the locking block 8 is pressed into the sliding through hole 7. Continue to pull down the toggle piece. When the toggle piece leaves the locking block 8, the locking block 8 will return to its original position after the deformation of the first return spring 10 removes the external force, so that the toggle piece is located in the locking space formed between the locking block 8 and the fixing block 13. Furthermore, the fixing block 13 can hold the toggle piece in place under the action of the second return spring 14, thereby achieving position locking of the toggle piece.

[0058] To release the position lock of the toggle switch, press the locking block 8 and pull the toggle switch on the air switch body 1 upward to the outside of the locking block 8 relative to the air switch body 1, thereby releasing the position lock of the toggle switch.

[0059] To facilitate the movement of the toggle switch into the locking space, such as Figure 1 As shown, the upper end of the card block 8 is a wedge-shaped structure facing the outside of the air switch body 1.

[0060] It should also be noted that the present invention sets a locking component on the main body of the air switch, and uses the cooperation between the locking block and the fixing block to form a locking space to lock the position of the toggle piece. At the same time, under the action of the return spring, the fixing block and the locking block work together to effectively lock the position of the toggle piece, thereby preventing the operator from accidentally operating the air switch.

[0061] In one specific embodiment, such as Figure 1 , 4 As shown, the mounting components include a first mounting block 2 and a second mounting block 3;

[0062] The first mounting block 2 and the second mounting block 3 are positioned opposite each other. Each of the first mounting block 2 and the second mounting block 3 is provided with an auxiliary clamping member 4 on the side that is far away from each other. The auxiliary clamping member 4 is used to fix the first mounting block 2 and the second mounting block 3 to the air switch body 1.

[0063] In this embodiment, both the first mounting block 2 and the second mounting block 3 are made of a composition of ABS engineering plastic.

[0064] The composition of ABS engineering plastics includes acrylonitrile-butadiene-styrene copolymer.

[0065] It should be noted that all parts used are made of ABS engineering plastic. The composition of ABS engineering plastic includes acrylonitrile-butadiene-styrene copolymer, which is a resin mixture formed by copolymerizing acrylonitrile, butadiene and styrene, which is then heated, extruded and molded. The resulting parts have a stable structure. ABS engineering plastic has high strength and rigidity, which allows it to provide sufficient structural support and resistance to deformation when manufacturing parts. It also has excellent impact resistance, which can absorb and disperse impact forces, making it less prone to breakage or cracking when subjected to impact or vibration. At the same time, it has good molding properties, and can be used to manufacture complex-shaped parts through injection molding, extrusion and blow molding, thus achieving a long service life.

[0066] In order to make the clamping more reliable, there can be two auxiliary clamping parts 4. The two auxiliary clamping parts are located on both sides of the mounting assembly to clamp the air switch body 1 of different sizes and specifications.

[0067] like Figure 5 As shown, the auxiliary clamping component 4 includes a clamping plate 401, a first lead screw 402, a first bearing 403, and a moving plate 404, with the clamping plate 401 and the moving plate 404 arranged opposite to each other.

[0068] After the first lead screw 402 passes through the through hole in the clamping plate 401, it is rotatably connected to the first bearing 403. The first bearing 403 is fixedly embedded in the through hole in the moving plate 404. The moving plate 404 moves relative to the clamping plate 401 under the rotation of the first lead screw 402.

[0069] A sliding piece 405 is provided on one side of the movable plate 404, and both the first mounting block 2 and the second mounting block 3 are provided with a sliding groove 15 that is slidably connected to the sliding piece 405.

[0070] Specifically, when the air switch body 1 is in its smallest size, turning the first lead screws 402 on both sides pushes the moving plate 404 to move within the slide groove 15, thereby fixing the first mounting block 2 and the second mounting block 3 to the outer surfaces on both sides of the air switch body 1. Simultaneously, the arrangement of the slide groove 15 and the sliding plate 405 improves the stability of the moving plate 404 during sliding, enhancing ease of use.

[0071] like Figures 6-7 As shown, the air switch latch for preventing accidental operation provided in this embodiment also includes a moving component;

[0072] The moving assembly includes a second lead screw 18, an adjusting knob 19, and a second bearing 20;

[0073] A finger groove 16 is provided at the connection between the first mounting block 2 and the second mounting block 3. A threaded hole 17 is provided on the side of the second mounting block 3 opposite to the finger groove 16. One end of the second lead screw 18 is threadedly connected to the threaded hole 17. An adjustment knob 19 is fixedly provided on the outer surface of the second lead screw 18. The other end of the second lead screw 18 is rotatably connected to the second bearing 20. The second bearing 20 is fixedly embedded in the bearing groove provided on the side of the first mounting block 2 opposite to the finger groove 16.

[0074] Specifically, turning the adjustment knob 19 drives the second lead screw 18 to rotate. With the finger groove 16, it is convenient to manually turn the adjustment knob 19. Furthermore, with the threaded hole 17, the second mounting block 3 can be moved. This allows for adjustment according to the model of the air switch body 1, thereby fixing the first mounting block 2 and the second mounting block 3 to the outer surface of the air switch body 1.

[0075] Understandably, the finger groove 16 allows for easy rotation of the adjustment knob 19, improving the efficiency of the device.

[0076] like Figure 2 , 7 As shown, the moving component also includes two sliders 11 and 110;

[0077] There are two locking blocks 8, which are arranged opposite to each other. One end of the slide rod 11 is fixedly connected to the surface of one of the locking blocks, which is close to the surface of the other locking block. The other end of the slide rod 11 is slidably connected to the groove provided in the other locking block.

[0078] One end of the slide rod 110 is fixedly connected to the surface of the first mounting block 2, which is relatively close to the surface of the second mounting block 3, and the other end of the slide rod 110 is slidably connected to the groove provided in the second mounting block 3.

[0079] Specifically, with the slide bar 11, the two locking blocks can be separated and fitted to accommodate different sizes. At the same time, with the slide bar 110, the first mounting block 2 and the second mounting block 3 can be separated and fitted to accommodate different sizes, and it is also convenient for both sides to move at the same time, thereby improving the ease of use.

[0080] like Figure 8 As shown, the air switch latch for preventing misoperation provided in this embodiment also includes an identification component 5, which is disposed on the mounting component.

[0081] The signage component 5 includes a hook 501, a tension spring 502, a mounting plate 503, a connecting ring 504, and a sign 505.

[0082] The first mounting block 2 and the second mounting block 3 are respectively provided with mounting holes 6 on the side that are relatively far apart from each other, which are adapted to the structure of the hook 501.

[0083] The two ends of the tension spring 502 are fixedly connected to the bottom of the hook 501 and the mounting hole 6, respectively;

[0084] The mounting plate 503 is snapped onto the hook 501, and one side of the mounting plate 503 is rotatably connected to the sign 505 via the connecting ring 504.

[0085] Specifically, after locking the switch, pull the hook 501 to slide it out of the mounting hole 6, then snap the mounting plate 503 into the inside of the hook 501. Then, under the setting of the tension spring 502, the hook 501 can be pulled back, thus fixing the mounting plate 503 inside the hook 501. And under the setting of the connecting ring 504, the sign 505 can be hung below the air switch body 1. The sign 505 can have relevant warning signs written on it, such as "Operation Prohibited", thereby improving the warning effect and allowing signs of different sizes to be hung, thus improving safety.

[0086] The sign 505 is wider than the mounting plate 503, which facilitates its warning function and improves safety.

[0087] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
