Description

Technical Field

[0001] This utility model relates to a switch operating handle, belonging to the technical field of low-voltage switchgear. Background Technology

[0002] Some existing electrical switches use a relatively traditional handle rotation method for operation. For example, high and low voltage disconnect switches, molded case switches, and knife fuse switches are usually equipped with a simple handle that is manually operated. After gripping the handle with one hand, the switch is turned clockwise or counterclockwise to open or close.

[0003] High and low voltage disconnect switches mainly consist of moving and stationary contacts, operating mechanisms, insulating supports, and conductive arms. During operation, the disconnect switch must only be operated after the circuit breaker has disconnected the circuit to prevent arcing caused by opening and closing under load. Manual operation of high and low voltage disconnect switches via a handle presents a challenge in terms of effort. This is because the handles mounted on the cabinet are generally short and close to the cabinet, just large enough for one person to hold with one hand. However, manual operation requires overcoming the contact pressure of the moving and stationary contacts, often requiring a significant operating torque. The short handle necessitates greater operating force, easily leading to hand fatigue for the operator.

[0004] Therefore, to make the switch operation more effortless and comfortable, a two-handed operating handle is added to the original handle to achieve the same effect. It is temporarily attached to the original switch handle during use, and can be easily removed for storage without affecting the normal layout of the cabinet. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a switch operating handle that solves the problems of current switch handles being not labor-saving and difficult to operate.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0007] A switch operating handle, comprising:

[0008] The handle body is composed of a clamp, a bending part, and a wing part. The clamp has an inner groove that can be fitted onto the original handle. The clamp has symmetrically connected bending parts on both sides that deflect away from the original handle. Each bending part is connected to a wing part that is parallel to the original handle at its end.

[0009] The handle sleeve fits snugly onto the symmetrically arranged wings on both sides of the clamp.

[0010] Preferably, the clamp is a C-shaped clamp.

[0011] Preferably, the handle sleeve is an insulating silicone sleeve with an opening at one end.

[0012] Preferably, the thickness of the wing portion is greater than that of the bent portion, and a step is formed at the connection between the wing portion and the bent portion to prevent the opening of the insulating silicone sleeve from detaching.

[0013] Preferably, the surface of the handle body is provided with an insulating plastic layer.

[0014] Preferably, the clamp has a hollow hole.

[0015] The beneficial effects of this utility model are as follows: A two-handed operating handle is added to the original handle, which can only be operated with one hand. A clamp is used to fit the handle body onto the shorter original handle. By holding the wing part, which is far from the original handle, with both hands, force is applied to the original handle, making it more effortless and comfortable compared to one-handed operation. Because the wing part is far from the original handle and cabinet, it does not collide during rotation. Furthermore, the silicone handle sleeve is non-slip, prevents slippage, and does not injure hands. The clamp structure makes it easy to remove and can be placed next to the equipment when not in use.

[0022] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0023] like Figure 1 As shown, the switch operating handle includes: a handle body 1, and a handle sleeve 2 fitted onto the handle body 1.

[0024] like Figures 2-5As shown, the handle body 1 is made of a single piece of metal and includes a clamp 101, a bending portion 102, and a wing portion 103. The clamp 101 has a C-shaped cross-section and an inner groove 104 is formed inside the clamp 101. The clamp 101 is fitted onto the original handle 3 through the inner groove 104 to form a fixed shape. The bending portions 102 are symmetrically connected to both sides of the clamp 101. The bending portions 102 are bent away from the original handle 3. The wing portion 103 is connected to the end of the bending portion 102 and is parallel to the original handle 3, forming a hand-held part that can be operated by both hands away from the original handle 3.

[0025] The handle sleeve 2 is made of flexible insulating silicone sleeve 201, which fits tightly onto the symmetrically arranged wing parts 103 on both sides of the clamp 101 through a small opening 202 at one end.

[0026] The original handle 3 can only be operated with one hand. For switches on high-current switching equipment, a large torque is required to open them, making one-handed operation inconvenient. Therefore, a handle body 1 that can be operated with both hands is added to the original handle 3. A clamp 101 is used to fit the handle body 1 onto the shorter original handle 3. By gripping the wing part 103 away from the original handle 3 with both hands, force is applied to the original handle 3. At this time, the wing part 103 held by both hands is away from the original handle 3 and the cabinet 4, so it will not interfere with the grip. Moreover, even if it suddenly loosens during forceful operation, it will not scratch the original handle 3 and the cabinet 4, making it safer. When operating with both hands, whether lifting or pressing, the clamp 101 always maintains force transmission with the side of the original handle 3 in a surface contact manner, avoiding the formation of an overly concentrated force point on the handle and preventing damage to the original handle 3. The double-wing structure extends the original handle on one side and adds an auxiliary gripping part for force application on the other side. The combination of the two achieves a force-saving effect.

[0027] Two-handed operation is more labor-saving and comfortable than one-handed operation, reducing the force required and the impact; and the silicone handle sleeve 2 is non-slip, non-detachable, and does not hurt the hands; the clamp 101 structure is easy to remove and can be placed in a conspicuous place next to the equipment when not in use.

[0028] Effort-saving design is achieved through mechanical structure optimization, making it suitable for high and low voltage disconnect switches, circuit breakers, or other mechanical switches that require greater operating force.

[0029] In some embodiments, the thickness of the wing portion 103 is greater than that of the bent portion 102, and a step 105 is formed at the connection between the wing portion 103 and the bent portion 102 to prevent the opening 202 of the insulating silicone sleeve 201 from detaching.

[0030] By relying on the step 105 formed by the larger wing portion 103 than the bending portion 102, and by opening a smaller opening 202 at one end of the insulating silicone sleeve 201, during installation, the opening 202 is pulled open and the sleeve is put on from the end of the wing portion 103 all the way to the bending portion 102. The smaller opening 202 is blocked at the step 105, which can prevent the insulating silicone sleeve 201 from falling off.

[0031] In some embodiments, an insulating plastic layer is provided on the surface of the handle body 1.

[0032] The handle body 1, covered with an insulating plastic layer, provides insulation, enhancing safety. It also allows for contact with the original handle 3 through the insulating plastic layer, preventing direct metal-to-metal contact and potential scratches. The insulating plastic layer can be formed using a powder coating process.

[0033] In some embodiments, the clamp 101 has a hollow hole 106.

[0034] While maintaining the preset strength, the hollow hole 106 can reduce the weight, making it lighter and more convenient to use, and also reducing the amount of metal materials required to make the handle body 1.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
