Description

Technical Field

[0001] This utility model belongs to the technical field of low-voltage switchgear operating handles, specifically a protective device for low-voltage switchgear operating handles. Background Technology

[0002] With the widespread application of modern industry and power equipment, electrical equipment such as low-voltage switchgear has become a core component in power distribution and control systems. The operating handle of the low-voltage switchgear, as a key component connecting human-machine interaction, undertakes the functions of equipment switching, adjustment and control.

[0003] Traditional operating handles are often of fixed length and mostly exposed. When the low-voltage cabinet is in normal operation, the handle is prone to misoperation due to accidental collisions (such as personnel movement or tool collisions), which can lead to equipment failure or even safety accidents. To address this, we have proposed a protective device for the operating handle of the low-voltage cabinet. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a protective device for a low-voltage switchgear operating handle, comprising a base, a handle body mounted on the base, folding grooves on both sides of the handle body, a partition between the two folding grooves, a rotating shaft at the tail of each folding groove, two rotating shafts symmetrically arranged at the tail of the handle body, folding grips rotatably mounted on both rotating shafts, a first magnet group on each opposite side of the two folding grips, the first magnet group comprising multiple first magnets symmetrically distributed on the sides of the two folding grips, the opposite poles of the first magnets on the two folding grips facing each other, a second magnet group at the tail of the folding grip and the head of the folding groove, the second magnet group comprising multiple second magnets, the opposite poles of the multiple second magnets facing each other, an opening on the handle body, and the partition used to prevent excessive rotation of the folding grip, providing support during operation and better force application.

[0005] Preferably, the folding handle has an arc structure with a streamlined design and anti-slip texture, making the handle fit the palm better and improving grip stability during operation.

[0006] Preferably, the rotating shaft and the folding handle are both made of stainless steel, titanium alloy or aluminum alloy. The use of high-strength materials enhances the durability and environmental adaptability of the rotating shaft and the folding handle.

[0007] Preferably, the base is provided with indicator marks, and the handle body is provided with indicator arrows. The intuitive marks and arrows reduce the risk of misoperation and improve the ease of operation of the device.

[0008] Preferably, the indicator and the arrow are coated with a luminescent paint, which is made of zinc sulfide or chlorate, to ensure that the indicator and the arrow are clearly visible in low-light environments, facilitating operation at night or in a dark room.

[0009] Preferably, the handle body and the surface of the folding grip are provided with an insulating coating, which is made of rubber material, to effectively prevent the risk of electric leakage during operation and ensure the safety of the operator.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] In the folded state, the folding handle folds inward via the rotation axis and embeds into the folding slots on both sides of the handle body. The second set of magnets uses the attraction of opposite poles to fix the tail of the folding handle in the folding slot. When it needs to be unfolded, the operator gently pulls the folding handle through the unfolding opening to release it from the attraction of the second set of magnets. The folding handle rotates and unfolds along the rotation axis. It is limited by the partition. The unfolded folding handle and the handle body form a rigid linear structure. The first set of magnets attracts and fixes the two handles together. The handles are used to transmit force to the mechanical operating mechanism of the device. The anti-slip texture and curved structure provide a better grip experience. In the non-operating state, the handle can be folded and stored in the handle body to reduce space occupation and prevent accidental damage. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Depend on Figure 1-2 The present invention includes a base 1, on which a handle body 2 is mounted. Folding grooves 3 are respectively formed on both sides of the handle body 2, and a partition is provided between the two folding grooves 3. A rotating shaft 4 is provided at the tail of each folding groove 3. Two rotating shafts 4 are symmetrically arranged at the tail of the handle body 2. Folding handles 5 are rotatably mounted on both rotating shafts 4. A first magnet group 6 is provided on the opposite side of each of the two folding handles 5. The first magnet group 6 includes multiple first magnets symmetrically distributed on the sides of the two folding handles 5, with opposite poles facing each other. A second magnet group 7 is provided at the tail of the folding handle 5 and the head of the folding groove 3. The second magnet group 7 includes multiple second magnets with opposite poles facing each other. An opening 8 is provided on the handle body 2. The partition is used to prevent excessive rotation of the folding handles 5, providing support during operation and allowing for better force application.

[0018] The folding handle 5 features an arc structure 9 with a streamlined design and anti-slip texture, making the handle fit the palm better and improving grip stability during operation.

[0019] Both the rotating shaft 4 and the folding grip 5 are made of stainless steel, titanium alloy, or aluminum alloy. The use of high-strength materials enhances the durability and environmental adaptability of the rotating shaft 4 and the folding grip 5.

[0020] The base 1 is equipped with an indicator mark 10, and the handle body 2 is equipped with an indicator arrow 11. The intuitive marks and arrow prompts reduce the risk of misoperation and improve the ease of operation of the equipment.

[0021] Both the indicator 10 and the indicator arrow 11 are coated with luminescent paint, which is made of zinc sulfide or chlorate. This ensures that the indicator and arrow are clearly visible in low-light environments, facilitating operation at night or in dark rooms.

[0022] The handle body 2 and the folding grip 5 are provided with an insulating coating. The insulating coating is made of rubber, which can effectively prevent the risk of electric leakage during operation and ensure the safety of the operator.

[0023] Working principle: In the folded state, the folding handle 5 folds inward via the rotating shaft 4 and is embedded in the folding grooves 3 on both sides of the handle body 2. The second magnet group 7 fixes the tail of the folding handle 5 in the folding groove 3 by the attraction of opposite poles. When it needs to be unfolded, the operator gently pulls the folding handle 5 through the unfolding opening 8 to release it from the attraction force of the second magnet group 7. The folding handle 5 rotates and unfolds along the rotating shaft 4. It is limited by the partition. The unfolded folding handle 5 and the handle body 2 form a rigid linear structure. The first magnet group 6 makes the two handles attract and fix each other. The handles are used to transmit force to the mechanical operating mechanism of the device. The anti-slip texture and curved structure 9 provide a better grip experience. In the non-operation state, the handle can be folded and stored in the handle body 2 to reduce space occupation and prevent accidental damage.
