Description

Technical Field

[0001] The utility model relates to the technical field of handle devices, in particular to an anti-static interference handle device. Background Art

[0002] During the installation of stage lighting equipment, especially when devices such as laser lights and smoke machines are fixed on metal trusses, since metal trusses are often shared with other electrical equipment, high-voltage static electricity is likely to accumulate on their surfaces. Once this static electricity is conducted to the inside of the chassis shell through the connected handle or other metal components, it may cause equipment failures, misoperations, and even safety accidents. Most of the existing handle devices are not specifically designed for static electricity protection and cannot effectively isolate and prevent static electricity conduction. Therefore, there are significant safety hazards when used in a high-static environment.

[0003] Traditional solutions usually rely on simple insulation material covering or grounding to disperse static electricity, but these methods may still have problems such as unstable electrical connections and non-durable insulation effects in actual applications. Therefore, how to effectively prevent static interference while ensuring the stable connection of the handle device has become an urgent technical problem to be solved. In view of the above problems, the utility model proposes an anti-static interference handle device. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problems raised in the above background art.

[0005] The utility model adopts the following technical scheme: an anti-static interference handle device, including a chassis shell and a handle body for fixing the chassis shell. The handle body is fixed on the surface of the chassis shell through a handle fixing block. An insulating pad for the handle is provided between the handle fixing block and the chassis shell. A convex insulating pad is inserted on the surface of the handle fixing block. A fixing screw is inserted inside the convex insulating pad. The fixing screw is threadedly connected between the insulating pad for the handle and the chassis shell after passing through the insulating pad for the handle. A hand-tightening screw is inserted on the surface of the handle body.

[0006] Preferably, both the insulating pad for the handle and the convex insulating pad are made of high-voltage-resistant insulating materials. Here, the insulation performance of the device is greatly improved, which can effectively prevent static electricity from being conducted to the chassis shell or internal electrical equipment through the handle body, avoiding equipment failures or safety accidents caused by static electricity discharge.

[0007] Preferably, a handle pressing block is fixedly installed at the connection between the hand-twist screw and the handle body. The hand-twist screw is threadedly connected between the handle body and the chassis housing, and the handle body is located between the handle pressing block and the handle fixing block. Here, the stability of the handle body is ensured, preventing loosening caused by vibration or external force. At the same time, by strengthening the connection between the handle and the chassis housing, the anti-static interference ability of the device is further improved.

[0008] Preferably, the electrical equipment in the chassis housing is isolated from the handle body through a handle insulating pad provided on the chassis housing. Here, possible static interference is effectively isolated outside the chassis housing, protecting the internal electrical equipment from static interference, extending the service life of the equipment, and reducing equipment malfunction or damage caused by static interference, thereby improving the stability and reliability of the entire system.

[0009] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0010] In the present utility model, the handle body and the chassis housing are effectively isolated by a high-voltage-resistant insulating material, significantly reducing the risk of static conduction and preventing equipment failures caused by static discharge. At the same time, the design of the hand-twist screw and the pressing block ensures the tight connection between the handle and the chassis, improving the stability and durability of the device. In addition, by isolating the electrical equipment in the chassis from the external static power source, static interference is reduced, the reliability and service life of the equipment are improved, making the device suitable for high-static environments, especially suitable for stage lighting equipment, and having a wide range of application prospects.

[0016] Embodiment

[0017] Please refer to Figure 1 , the present utility model provides a technical solution: an anti-static interference handle device, including a chassis housing 7 and a handle body 4 for fixing the chassis housing 7. The handle body 4 is fixed on the surface of the chassis housing 7 through a handle fixing block 2. An insulating pad 1 is provided between the handle fixing block 2 and the chassis housing 7. A boss insulating pad 3 is inserted on the surface of the handle fixing block 2. Both the handle insulating pad 1 and the boss insulating pad 3 are made of high-voltage-resistant insulating materials, greatly improving the insulation performance of the device. It can effectively prevent static electricity from being conducted from the handle body 4 to the chassis housing 7 or internal electrical equipment, avoiding equipment failures or safety accidents caused by static electricity discharge. A fixing screw is inserted inside the boss insulating pad 3, and the fixing screw is threadedly connected to the chassis housing 7 through the handle insulating pad 1. A hand-tightening screw 6 is inserted on the surface of the handle body 4. A handle pressing block 5 is fixedly installed at the connection between the hand-tightening screw 6 and the handle body 4. The hand-tightening screw 6 is threadedly connected to the chassis housing 7 through the handle body 4, and the handle body 4 is located between the handle pressing block 5 and the handle fixing block 2, ensuring the stability of the handle body 4 and preventing loosening caused by vibration or external force. At the same time, by strengthening the connection between the handle and the chassis housing 7, the anti-static interference ability of the device is further improved. The electrical equipment inside the chassis housing 7 is isolated from the handle body 4 through the handle insulating pad 1 provided on the chassis housing 7, effectively isolating possible static interference outside the chassis housing 7, protecting the internal electrical equipment from static interference, extending the service life of the equipment, and reducing equipment malfunction or damage caused by static interference, thereby improving the stability and reliability of the entire system.

[0018] Working principle: The handle body 4 is fixed on the surface of the chassis housing 7 through the handle fixing block 2. A handle insulating pad 1 is provided between the handle fixing block 2 and the chassis housing 7. A boss insulating pad 3 is inserted on the surface of the handle fixing block 2. Both the handle insulating pad 1 and the boss insulating pad 3 are made of high-voltage-resistant insulating materials, which can effectively prevent static electricity from being conducted from the chassis housing 7 to the handle body 4, avoiding the diffusion of static electricity to the external environment through the handle body 4 or causing electrical interference to the internal equipment of the chassis. A fixing screw is inserted inside the boss insulating pad 3, so that when the fixing screw connects the chassis housing 7, it is completely isolated from external static electricity interference, preventing the screw from becoming a path for static electricity conduction, thereby improving the insulation of the entire device and effectively protecting the electrical equipment inside the chassis. A handle pressing block 5 is fixedly installed at the connection between the hand-tightening screw 6 and the handle body 4. The handle body 4 is firmly fixed on the chassis housing 7 through the hand-tightening screw 6, which not only ensures the stability of the handle body 4 during long-term use and prevents loosening caused by vibration or external force, but also further improves the anti-static interference ability of the device by strengthening the tight connection between the handle and the chassis housing 7. The electrical equipment inside the chassis housing 7 is isolated from the handle body 4 through the handle insulating pad 1 provided on the chassis housing 7, ensuring that the electrical equipment inside the chassis is isolated from possible static electricity sources and preventing static electricity from interfering with and damaging the internal equipment, thereby improving the reliability and service life of the equipment.
