Description

TECHNICAL FIELD

[0001] The present application relates to the field of switch cabinets, in particular to an operating handle for a switch cabinet. BACKGROUND

[0002] In the current power system and electrical equipment operation scene, the switch cabinet as the core equipment, its operation accuracy and timeliness is very important. However, the existing switch cabinet operating handle, its operating head and handle body are integrally arranged. Because the switch cabinets produced by different manufacturers are various in model, the operation interface and operation requirement are also different, which leads to that the operation personnel must carry multiple types of operating handles when operating multiple models of switch cabinets.

[0003] This situation brings many disadvantages. On the one hand, a large number of operating handles increase the carrying burden of the operation personnel, occupy a large space, and need to be frequently replaced during operation, which also wastes a lot of working time. On the other hand, once it is found that a certain model of operating handle is missed when reaching the operation site, it needs to be returned to take, which further prolongs the power-off time of the equipment. The prolongation of the power-off time of the equipment not only affects the stable operation of the power system, but also brings economic loss and inconvenience to the users caused by power-off, reduces the satisfaction of the users to the power supply. SUMMARY

[0004] The present application aims to solve one of the problems in the related art to some extent. To this end, the present application provides an operating handle for a switch cabinet, which has the advantage of facilitating replacement of the operating head.

[0005] In order to achieve the above purpose, the present application adopts the following technical solutions: An operating handle for a switch cabinet, comprising a handle body and an operating head for inserting into a switch cabinet operating hole, the handle body comprising a handle and a movable rod, one end of the movable rod close to the handle being slidingly connected to the handle, one end of the movable rod away from the handle being provided with a plug-in interface, at least one end of the operating head being configured as a hollow structure and being detachably sleeved to the plug-in interface; a first limiting piece is arranged on the outer surface of the plug-in interface, and the first limiting piece can be clamped to the operating head to limit the separation of the operating head and the plug-in interface when the operating head is sleeved to the plug-in interface.

[0006] In the present application, the operating handle comprises a handle body and an operating head, and the operating head is detachably mounted on the handle body, so that the handle has better adaptability and maintainability in different use scenarios. The switch cabinet is provided with a plurality of operating holes, and the operating handle is used for being inserted into the operating hole. The operating handle is used by the worker to operate the switch cabinet to open and close, adjust the operation mode of the power grid, and realize the reasonable distribution and transmission of power. In the prior art, the operating handle is usually of an integral structure. When the equipment is damaged or needs to be upgraded, many drawbacks are exposed. Once the handle is damaged, the whole handle must be replaced, which not only directly increases the maintenance cost, but also reduces the availability of the equipment due to equipment downtime for maintenance, thereby affecting the production efficiency. Therefore, the present application provides an operating handle with a replaceable operating head to adapt to different shapes of operating holes in the switch cabinet. The worker only needs to carry one operating handle and a complete set of operating heads to complete a series of work, thereby saving a lot of working time, reducing power outage time, and reducing the impact of user power outage.

[0007] Optionally, the plug-in interface is hollow and comprises a connecting part and a sleeve part arranged integrally, the connecting part is used for connecting with the rod body of the movable rod, and the sleeve part is used for sleeving the operating head, and the outer diameter of the sleeve part is smaller than the outer diameter of the connecting part.

[0008] The plug-in interface is designed as a hollow structure, which can not only realize the connection function with the movable rod and the operating head, but also reduce the weight and save the material. The plug-in interface comprises a connecting part and a sleeve part arranged integrally. The integral arrangement ensures the integrity and structural strength of the plug-in interface and reduces the risk of failure caused by loosening of the connecting part. The connecting part is used for connecting with the rod body of the movable rod, and the connecting part and the rod body of the movable rod are integrally connected in the present application, which is more firm. The sleeve part is used for sleeving the operating head, and the outer diameter of the sleeve part is smaller than the outer diameter of the connecting part, forming a stepped structure. The inner diameter and the length of the sleeve part are designed according to the size of the operating head, so as to ensure that the operating head can be smoothly sleeved and tightly fitted.

[0009] Optionally, the first limiting part comprises a spring and a steel ball, one end of the spring is fixedly connected to the inner surface of the sleeve part, the other end of the spring is fixedly connected to the steel ball, the sleeve part is provided with a through hole, and the diameter of the through hole is greater than the diameter of the steel ball, so that the steel ball can be extended out of the sleeve part through the through hole.

[0010] The spring is fixedly connected to the inner surface of the sleeve part at one end, and the material thereof is usually selected from metal materials with good elasticity, such as spring steel, so as to ensure that the spring can maintain the elastic property and is not prone to deformation during long-term use. The steel ball is fixedly connected to the other end of the spring, so that the spring provides the steel ball with the elastic force tending to move through the through hole. The sleeve part is part of the plug-in interface and is used for sleeving the operation head. The sleeve part is provided with a through hole, and the diameter of the through hole is greater than the diameter of the steel ball, so that the steel ball can partially protrude out of the sleeve part under the action of the spring, and the steel ball will not completely fall out of the through hole.

[0011] Optionally, a guide groove is formed in the inner wall of the operation head along the length direction of the inner wall. When the operation head is sleeved on the sleeve part and the guide groove is opposite to the first limiting piece, the steel ball extends into the guide groove. An end of the guide groove is provided with a limiting hole penetrating through the inner wall of the operation head. The limiting hole is in communication with the guide groove, and an elastic pressing piece fixed to the outer wall of the operation head is arranged outside the limiting hole.

[0012] The inner wall of the operation head is provided with a guide groove along the length direction of the inner wall. The guide groove has a strip shape and has a certain width and depth. The width and depth of the guide groove are designed according to the size of the steel ball, so as to ensure that the steel ball can smoothly extend into the guide groove and have a certain movement space in the guide groove. The first limiting piece is composed of a spring and a steel ball. The steel ball can be clamped in the limiting hole under the action of the spring, so as to limit the separation of the operation head and the plug-in interface.

[0013] Optionally, the limiting hole includes an inclined side wall, and the width of the limiting hole gradually decreases in a direction away from the guide groove.

[0014] The inclined side wall and the structure of wide at the top and narrow at the bottom simplify the assembly process of the operation head. When the operation head is sleeved on the sleeve part, the positions of the steel ball and the limiting hole do not need to be accurately aligned. The steel ball can smoothly enter the limiting hole under the guidance of the inclined side wall only by roughly sleeving the operation head. The operation difficulty and time in the assembly process are reduced, and the production efficiency is improved. This structure is especially suitable for large-scale production and on-site rapid assembly.

[0015] Optionally, the movable rod is hollow, and connecting holes are formed in opposite sides of the movable rod. The handle is arranged in the two connecting holes, so that the handle and the movable rod slide relative to each other.

[0016] The movable rod is hollow to reduce the overall weight of the movable rod, making the operating handle lighter and easier for the operator to hold and operate for a long time. Meanwhile, the hollow structure can also provide space for internal wiring or installation of other components in some electrically operated handles. Connection holes are formed on opposite sides of the movable rod, and the two connection holes are symmetrically distributed to ensure that the grip can remain balanced and stable after being threaded. The diameter of the connection holes is adapted to the diameter of the grip to allow the grip to be smoothly threaded and limit the shaking of the grip, ensuring the smoothness of relative sliding.

[0017] Optionally, the grip is provided with a plurality of first positioning holes along the axial direction thereof, and the end of the movable rod close to the grip is provided with a second positioning hole, and the second positioning hole is selectively connected with one of the first positioning holes through a positioning pin.

[0018] The grip is provided with a plurality of first positioning holes along the axial direction thereof, which can be uniformly distributed or non-uniformly distributed. When uniformly distributed, the spacing between adjacent holes is fixed, which can provide regular position adjustment options for the operator; when non-uniformly distributed, it can be set according to the operation requirements and use habits, for example, more accurate positioning is required in some specific operation positions, so more dense first positioning holes are arranged in this area. The diameter of the first positioning hole is matched with the positioning pin, so that the positioning pin can be smoothly inserted and firmly fixed.

[0019] Optionally, a flexible connecting band is fixed on the movable rod, and one end of the flexible connecting band away from the movable rod is fixedly connected with the positioning pin.

[0020] During operation, when the grip position needs to be adjusted and the positioning pin is pulled out, the positioning pin is connected with the movable rod through the flexible connecting band, avoiding the loss of the positioning pin due to random placement. Especially in outdoor operation scenarios, the positioning pin can be used at any time, without affecting subsequent operation.

[0021] Optionally, the two ends of the grip are provided with second limiting members protruding from the surface of the grip.

[0022] The second limiting members protrude from the surface of the grip and form an obstruction in the relative movement path of the movable rod and the grip. When the movable rod has a tendency to come out, the limiting members will contact and block the end of the movable rod, preventing it from moving further, thereby preventing the movable rod from coming out of the grip completely.

[0023] Optionally, the axial direction of the grip and the axial direction of the movable rod are perpendicular to each other.

[0024] The perpendicularity between the handle's axis and the moving rod's axis allows for easier operation. The handle's perpendicularity to the moving rod effectively provides the operator with a larger radius of rotation. When the operator rotates the handle, this larger radius of rotation means that, at the same angular velocity, the linear velocity of the handle's end is greater, making it easier to rotate the moving rod.

Detailed Implementation

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain the present invention and should not be construed as limiting the invention.

[0029] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this patent. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0030] Example: like Figure 1As shown, this embodiment provides an operating handle for a switch cabinet, including a handle body and an operating head 3 for inserting into the switch cabinet operating hole. The handle body includes a grip 1 and a movable rod 2. The end of the movable rod 2 near the grip 1 is slidably connected to the grip 1, and the end of the movable rod 2 away from the grip 1 is provided with a plug-in interface 21. At least one end of the operating head 3 is constructed as a hollow structure and is detachably sleeved on the plug-in interface 21. A first limiting member 22 is provided on the outer surface of the plug-in interface 21. When the operating head 3 is sleeved on the plug-in interface 21, the first limiting member 22 can be locked onto the operating head 3 to prevent the operating head 3 from separating from the plug-in interface 21.

[0031] In this embodiment, the operating handle includes a handle body and an operating head 3, with the operating head 3 detachably mounted on the handle body. This allows the handle to have better adaptability and maintainability in different usage scenarios. The switchgear has multiple operating holes, and the operating handle is inserted into these holes. Operators use the operating handle to perform opening and closing operations on the switchgear, adjust the power grid's operation mode, and achieve reasonable power distribution and transmission. In the prior art, operating handles are mostly of a single integrated structure. This structure exposes many drawbacks when facing equipment damage or upgrade requirements. Once the handle malfunctions, the entire unit must be replaced, which not only directly increases maintenance costs but also reduces equipment availability due to downtime for maintenance, affecting production efficiency. Therefore, this embodiment proposes an operating handle with a replaceable operating head 3 to adapt to operating holes of different shapes within the switchgear. Operators only need to carry one operating handle and a complete set of operating heads 3 to complete a series of tasks, saving significant working time, reducing power outage time, and minimizing the impact of power outages on users. Furthermore, when the operating head 3 is damaged, only the operating head 3 needs to be replaced.

[0032] The handle body includes a grip 1 and a movable rod 2. The grip 1, which is directly held by the operator, may be made of a material with sufficient strength, such as stainless steel, to meet the strength requirements for daily use. The end of the movable rod 2 closest to the grip 1 is slidably connected to it, allowing adjustment of their relative positions and improving operational flexibility. The end of the movable rod 2 furthest from the grip 1 has a plug-in interface 21 for connecting to the operating head 3. The movable rod 2 is generally made of a metal material, such as stainless steel, to ensure sufficient strength and rigidity to withstand various forces generated during operation. At least one end of the operating head 3 is hollow, allowing it to fit onto the plug-in interface 21 of the movable rod 2. The shape and size of the operating head 3 are typically designed according to the specific requirements of the switchgear operating hole to ensure insertion into the hole. A first limiting member 22 is provided on the outer surface of the plug-in interface 21, which engages with the operating head 3 when it is fitted onto the interface 21, thus preventing separation between the operating head 3 and the interface 21.

[0033] In summary, the detachable connection between the operating head 3 and the movable rod 2 allows the handle to be quickly replaced with the appropriate operating head 3 according to different switchgear operating hole types and operational requirements. For example, different types of switchgear may require different shapes and sizes of operating heads 3. By changing the operating head 3, one handle can adapt to multiple operating scenarios, improving the versatility and practicality of the handle. The first limiting member 22 prevents the operating head 3 from separating from the plug-in interface 21 during operation, avoiding operational interruptions or safety accidents caused by the operating head 3 falling off.

[0034] The plug-in interface 21 is hollow and includes an integrally formed connecting part 211 and a sleeve part 212. The connecting part 211 is used to connect with the rod body of the movable rod 2, and the sleeve part 212 is used for the operating head 3 to be sleeved. The outer diameter of the sleeve part 212 is smaller than the outer diameter of the connecting part 211.

[0035] In this embodiment, the plug-in interface 21 is designed as a hollow structure, which, while enabling connection with the movable rod 2 and the operating head 3, also reduces weight and saves materials. The plug-in interface 21 consists of an integrally formed connecting part 211 and a sleeve part 212. This integral design ensures the integrity and structural strength of the plug-in interface 21, reducing the risk of failure due to loosening of the connecting part 211. The connecting part 211 is used to connect with the rod body of the movable rod 2, and in this embodiment, the connecting part 211 and the rod body of the movable rod 2 are integrally connected, making it more robust. The sleeve part 212 is for the operating head 3 to fit into, and its outer diameter is smaller than that of the connecting part 211, forming a stepped structure. The inner diameter and length of the sleeve part 212 are designed according to the size of the operating head 3 to ensure that the operating head 3 can be smoothly inserted and tightly fitted. In this embodiment, when the operating head 3 is fitted into the socket 212, the two are in a clearance fit, with a certain gap between the operating head 3 and the socket 212. However, the first limiting member 22 ensures that the operating head 3 will not easily fall off after being fitted. The stepped structure formed by the outer diameter of the socket 212 being smaller than the outer diameter of the connecting part 211 provides guidance for the fitting of the operating head 3. When fitting the operating head 3, the operator can fit it into the socket 212 more quickly and accurately, reducing operation time and difficulty, and improving work efficiency.

[0036] like Figure 1 and Figure 2 As shown, the first limiting member 22 includes a spring 221 and a steel ball 222. One end of the spring 221 is fixed to the inner surface of the sleeve portion 212, and the other end is fixed to the steel ball 222. The sleeve portion 212 has a through hole with a diameter larger than that of the steel ball 222 so that the steel ball 222 protrudes from the sleeve portion 212 through the through hole.

[0037] In this embodiment, one end of the spring 221 is fixedly connected to the inner surface of the sleeve portion 212. Its material is typically a metal with good elasticity, such as spring steel 221, to ensure that it maintains its elasticity and is not easily deformed during long-term use. The steel ball 222 is fixedly connected to the other end of the spring 221 so that the spring 221 provides it with a spring force that tends to move towards the through hole. The sleeve portion 212 is part of the plug-in interface 21 and is used to engage the operating head 3. A through hole is provided in the sleeve portion 212, the diameter of which is slightly larger than the diameter of the steel ball 222, allowing the steel ball 222 to partially extend out of the sleeve portion 212 under the action of the spring 221, while not completely disengaging from the through hole. When the operating head 3 is engaged in the sleeve portion 212, pressing the extended steel ball 222 causes it to overcome the spring force of the spring 221 and move into the sleeve portion 212, releasing it from the engagement with the operating head 3. Specifically, when installing the first limiting member 22, one end of the spring 221 can be installed inside the sleeve part 212 through the through hole, and then the other end can be pulled out of the through hole and fixed to the steel ball 222.

[0038] The inner wall of the operating head 3 is provided with a guide groove 31 along its own length direction. When the operating head 3 is sleeved on the sleeve part 212 and the guide groove 31 is opposite to the first limiting member 22, the steel ball 222 extends into the guide groove 31. The end of the guide groove 31 is provided with a limiting hole 32 that penetrates the inner wall of the operating head. The limiting hole 32 communicates with the guide groove. An elastic pressing member 223 fixed to the outer wall of the operating head is provided on the outside of the limiting hole 32.

[0039] In this embodiment, a guide groove 31 is formed on the inner wall of the operating head 3 along its length. The guide groove 31 is elongated and has a certain width and depth. The width and depth of the guide groove 31 are designed according to the size of the steel ball 222 to ensure that the steel ball 222 can smoothly extend into the groove and has sufficient space to move within it. The first limiting member 22 consists of a spring 221 and the steel ball 222. The steel ball 222 can extend out of the sleeve portion 212 under the action of the spring 221. When the operating head 3 is sleeved on the sleeve portion 212 and the guide groove 31 is opposite to the first limiting member 22, the steel ball 222 will extend into the guide groove 31. At this time, there is a gap between the steel ball 222 and the inner wall of the guide groove 31, so the steel ball 222 can move along the length of the inner wall of the operating head 3, and the guide groove 31 will not interfere with the steel ball 222. Since the operating head 3 also moves along its own length and sleeves onto the insertion / removal opening, the operating head 3 can smoothly sleeve onto the insertion / removal opening. After the connection is complete, simply press the elastic pressing member 223, and the steel ball 222 will disengage from the limiting hole 32. At this time, the steel ball 222 no longer restricts the separation of the operating head 3 and the plug-in interface 21. The guide groove 31 is coaxially arranged and connected with the limiting hole 32. The steel ball 222 is engaged with the limiting hole 32 to restrict the axial relative movement between the two. The elastic pressing member 223 is fixed to the outer wall of the operating head 3 to block the limiting hole 32. When the elastic pressing member 223 is pressed, the elastic pressing member 223 can deform and transmit the pressure to the steel ball 222 through contact. The steel ball 222 moves away from the limiting hole 32, and finally releases the axial restriction between the operating head 3 and the plug-in interface 21. Specifically, the elastic pressing member 223 can be an elastic metal sheet.

[0040] The limiting hole 32 includes an inclined sidewall, and the width of the limiting hole 32 gradually decreases in the direction away from the guide groove 31.

[0041] In this embodiment, the inclined sidewalls and the groove shape (wider at the top and narrower at the bottom) simplify the assembly process of the operating head 3. When the operating head 3 is fitted onto the socket 212, it is not necessary to precisely align the steel ball 222 and the limiting hole 32. Simply fitting the operating head 3 roughly allows the steel ball 222 to smoothly enter the limiting hole 32 under the guidance of the inclined sidewalls. This reduces the difficulty and time required during assembly, improving production efficiency, and is particularly suitable for large-scale production and rapid on-site assembly scenarios. When it is necessary to unlock the operating head 3, the inclined sidewalls allow the steel ball 222 to slide out of the limiting hole 32 relatively smoothly. The operator only needs to press the elastic pressing member 223, eliminating the need for complex tools or cumbersome operations, thus improving the convenience and efficiency of operation, especially suitable for situations requiring frequent insertion and removal of the operating head 3.

[0042] The movable rod 2 is hollow and has connecting holes 23 on both sides. The handle 1 passes through the two connecting holes 23 so that the handle 1 and the movable rod 2 can slide relative to each other.

[0043] In this embodiment, the movable rod 2 is hollow to reduce its overall weight, making the operating handle lighter and easier for operators to hold and operate for extended periods. Additionally, the hollow structure in some electric operating handles may provide space for internal wiring or the installation of other components. Connecting holes 23 are symmetrically distributed on opposite sides of the movable rod 2 to ensure the grip 1 remains balanced and stable after insertion. The diameter of the connecting holes 23 matches the diameter of the grip 1, allowing it to slide smoothly and limiting its wobbling, ensuring smooth relative sliding. The connecting holes 23 provide a sliding channel for the grip 1, and a certain gap exists between the grip 1 and the inner wall of the connecting holes 23. This gap allows the grip 1 to slide freely without being too large to cause excessive wobbling during sliding. When the operator applies a force along the axial direction of the grip 1, the grip 1 slides within the connecting holes 23 in the direction of the force, thus achieving relative movement between the grip 1 and the movable rod 2.

[0044] The handle 1 has multiple first positioning holes 11 along its own axis, and the movable rod 2 has a second positioning hole 25 at one end near the handle 1. The second positioning hole 25 is selectively connected to one of the first positioning holes 11 by a positioning pin 26.

[0045] In this embodiment, the grip 1 has multiple first positioning holes 11 along its own axial direction. These first positioning holes 11 can be evenly or unevenly distributed. When evenly distributed, the spacing between adjacent holes is fixed, providing the operator with a regular position adjustment option. Uneven distribution may be set according to operational needs and usage habits; for example, if more precise positioning is required in certain specific operating positions, more densely packed first positioning holes 11 will be set in that area. The diameter of the first positioning holes 11 matches the positioning pin 26, allowing the positioning pin 26 to be smoothly inserted and securely fixed. A second positioning hole 25 is formed at the end of the movable rod 2 near the grip 1, its position corresponding to the first positioning hole 11 on the grip 1, so that the positioning pin 26 can pass through both simultaneously to achieve connection. The size of the second positioning hole 25 must also be adapted to the positioning pin 26 to ensure a tight connection. The positioning pin 26 is used to connect the grip 1 and the movable rod 2, and the length of the positioning pin 26 can pass through both the second positioning hole 25 and the selected first positioning hole 11 simultaneously, and it remains stable after insertion, without easily loosening or falling off.

[0046] A flexible connecting strip 24 is fixed on the movable rod 2, and the end of the flexible connecting strip 24 away from the movable rod 2 is fixedly connected to the positioning pin 26.

[0047] In this embodiment, during operation, when the position of the handle 1 needs to be adjusted and the positioning pin 26 is pulled out, the positioning pin 26 is connected to the movable rod 2 via the flexible connecting strip 24, preventing the positioning pin 26 from being lost due to careless placement. Especially in outdoor operation scenarios, this ensures that the positioning pin 26 is always available and does not affect subsequent operations.

[0048] The handle 1 has a second limiting member 12 protruding from the surface of the handle 1 at both ends.

[0049] In this embodiment, the second limiting member 12 protrudes from the surface of the grip 1, forming a block on the relative movement path of the movable rod 2 and the grip 1. When the movable rod 2 tends to detach outward, the limiting member will contact and block the end of the movable rod 2, preventing it from continuing to move, thereby preventing the movable rod 2 from completely detaching from the grip 1. Specifically, the second limiting member 12 can be a rubber ring. First, a rubber ring is wrapped around one end of the grip 1, then the other end of the grip 1 is passed through the movable rod 2, and finally the rubber ring is wrapped around one end of the grip 1 that is passed through the movable rod 2.

[0050] The axis of handle 1 and the axis of moving rod 2 are perpendicular to each other.

[0051] In this embodiment, the perpendicularity of the axis of the handle 1 and the axis of the movable rod 2 makes operation easier for the operator. The perpendicularity of the handle 1 to the movable rod 2 provides the operator with a larger radius of rotation. When the operator rotates the handle 1, the larger radius of rotation means that, at the same angular velocity, the linear velocity of the end of the handle 1 is greater, making it easier to rotate the movable rod 2.

Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above.
