Description

Technical Field

[0001] This utility model relates to the technical field of switch anti-accidental contact devices, and in particular to an anti-accidental contact device and an emergency stop device for an emergency stop switch. Background Technology

[0002] Against the backdrop of increasingly tight global energy supplies, the new energy vehicle industry is booming and has become an important development direction in the future transportation sector. As a key infrastructure supporting the development of this industry, the safety and convenience of charging piles are of great concern. Emergency stop switches are safety control devices used to quickly cut off the power supply to charging piles or stop their operation in emergency situations. Emergency stop switches typically adopt a push-button or rotary design; when pressed or rotated, the internal mechanical structure is immediately triggered to cut off the power supply or stop the equipment from operating.

[0003] Currently, the anti-accidental-touch devices for emergency stop switches are mainly designed as manual-tightening covers, snap-on covers, or disposable covers. However, whether it is a manual-tightening cover or a snap-on cover, it is often difficult to open quickly in an emergency. Non-professional operators may miss the best time to shut down due to unfamiliarity with the operation or misjudgment of direction, directly threatening personnel safety and equipment stability. At the same time, both require a large layout space, cannot be easily opened during use, and are easily interfered with by other structures. In addition, the processing cost of manual-tightening covers and snap-on covers is high; disposable covers need to be replaced frequently after use, often incurring material procurement costs, and the covers cannot be reused after use, which easily leads to resource waste and environmental pollution.

[0023] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0024] This embodiment discloses an anti-accidental touch device for an emergency stop switch, which enhances the efficiency of emergency stop operation in emergency situations while achieving the effect of preventing accidental touch under normal conditions, improving safety, and reducing the space occupied and manufacturing cost of the anti-accidental touch device.

[0025] See Figures 1 to 5 As shown, the anti-accidental contact device includes a cover plate 1 and a fixing member 2. A sliding groove 11 is provided in the cover plate 1. One end of the fixing member 2 passes through the sliding groove 11 and is fixed to the base B on which the emergency stop switch A is installed. The other end of the fixing member 2 is engaged with the sliding groove 11 so that the cover plate 1 can slide or rotate relative to the fixing member 2 to cover or expose the emergency stop switch A.

[0026] In this embodiment, under normal circumstances, the emergency stop switch A is covered by the cover plate 1 to prevent accidental contact, thus preventing unnecessary shutdown of the charging pile due to accidental contact, misoperation, or environmental interference; in case of an abnormal situation, the cover plate 1 can choose two methods to release the covered state of the emergency stop switch A to achieve emergency shutdown of the charging pile, specifically: (1) push the cover plate 1 to slide relative to the fixing member 2, see Figure 4 As shown, the cover plate 1 is pushed upward along the sliding groove 11 until the fixing member 2 abuts against the bottom end of the sliding groove 11, and the emergency stop switch A is exposed; (2) the cover plate 1 is rotated relative to the fixing member to expose the emergency stop switch A, see reference Figure 5 As shown, when the fixing member 2 abuts against the top of the sliding groove 11, the cover plate 1 can rotate relative to the fixing member 2, thereby exposing the emergency stop switch A.

[0027] Optionally, in this embodiment, the fixing member 2 is a stepped screw. In actual use, other screws or nails with fixing and snapping functions can be used to achieve fixing.

[0028] Optionally, both ends of the sliding groove 11 are arc-shaped. The arc-shaped structure matches the edge of the fixing member 2 better, which helps the fixing member 2 to better engage the top and bottom of the sliding end, and plays a role in strengthening the fixation during pushing and rotating.

[0029] Optionally, the cover plate 1 includes a blocking portion 12 adapted to the shape of the emergency stop switch A and a rotating portion 13 formed by protruding outward from the top of the blocking portion 12. One end of the sliding groove 11 extends to the top of the rotating portion 13, and the other end of the sliding groove 11 extends to the bottom of the blocking portion 12. The blocking portion 12, designed to adapt to the shape of the emergency stop switch A, helps to reduce material usage and save costs while achieving the blocking effect.

[0030] Optionally, a drain hole 14 is also provided at the bottom of the cover plate 1. The design of the drain hole 14 helps to drain water droplets accumulated inside the emergency stop switch A in wet conditions, preventing water droplets from affecting the operation of the emergency stop switch A.

[0031] This embodiment also discloses an emergency stop device, which includes an emergency stop switch A, a base B, and an anti-accidental contact device for the emergency stop switch as described above, wherein the emergency stop switch A is embedded in the base B.

[0032] Compared with existing technologies, the anti-accidental touch device and emergency stop device of this utility model exhibit advantages in several aspects. Firstly, while ensuring that the emergency stop switch A is not accidentally touched under normal conditions, it optimizes the operation process, making emergency stop operations more direct and faster, effectively reducing the risk of delays caused by complex operations. Secondly, the design of the sliding groove 11 within the cover plate 1 not only reduces material usage and manufacturing costs but also significantly reduces space occupation, making it more adaptable to various compact working environments. Furthermore, the overall design of this anti-accidental touch device and emergency stop device emphasizes environmental protection, using recyclable materials, meeting the requirements of green and sustainable development, and possessing great application potential.
