Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of emergency stop interlocking switches, and in particular relates to an emergency stop interlocking switch that prevents accidental contact. Background Technology
[0002] An emergency stop interlock switch is a safety control device used in emergency situations to quickly stop equipment operation and prevent accidental restart of the equipment. It is usually a manually operated switch, and its purpose is to immediately cut off the power source or control signal of the equipment in the event of an emergency, so that the equipment is in a safe stop state.
[0003] In situations where the operating space for some equipment is limited, protective housings are often used. Operators may need to frequently enter and exit the operating area. The housings protect the emergency stop interlock switch during equipment operation and effectively prevent accidental activation.
[0004] Currently, in special working environments with a large amount of dust and oil, oil and dust may enter the gaps of the protective cover, making it difficult to open or close. In this case, the anti-accidental touch function may fail, and frequent cleaning and maintenance are required to ensure its normal use.
[0005] To address the aforementioned issues, this application proposes an emergency stop interlocking switch designed to prevent accidental activation. Utility Model Content
[0006] The purpose of this utility model is to provide an emergency stop interlocking switch that prevents accidental contact, thereby solving the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0008] This utility model relates to an anti-accidental-touch emergency stop interlocking switch, comprising a switch body, a switch contact inside the switch body, an anti-accidental-touch cover on the outer side of the switch body, a transparent soft shell fixedly installed on the inner wall of the anti-accidental-touch cover, two sets of support blocks fixedly installed on the inner side wall of the anti-accidental-touch cover, each set of support blocks having a screw inside, a matching nut threaded onto the outer surface of each screw, a bracket fixedly installed on the outer surface of each matching nut, the bottom surface of each bracket being fixedly connected to the upper surface of the switch body, a lifting plate on the outer side of each screw, two telescopic rods fixedly installed on the bottom surface of each lifting plate, the bottom surface of each telescopic rod being fixedly connected to the upper surface of the switch body, and a locking ring fixedly installed on one side of the four lifting plates that are close to each other, the inner wall of the locking ring contacting the outer surface of the switch contact.
[0009] Furthermore, the upper surface of the switch body is provided with two sets of sockets, each set of sockets being located directly below the screw.
[0010] Furthermore, each of the support blocks has two disassembly pins threadedly connected to its inner wall, and the outer surface of each disassembly pin is threadedly connected to the inner wall of the anti-accidental contact cover.
[0011] Furthermore, a bearing is fixedly installed on the inner wall of each support block, and the inner wall of each bearing is fixedly connected to the outer surface of the screw.
[0012] Furthermore, a connecting pressure plate is fixedly installed on the upper surface of each of the lifting plates, and the upper surface of each connecting pressure plate is fixedly connected to the bottom surface of the support block.
[0013] Furthermore, each of the lifting plates has a through hole on its upper surface, and each of the screws passes through the through hole.
[0014] This utility model has the following beneficial effects:
[0015] This invention features an anti-accidental touch cover with an opening facing downwards and a fully enclosed appearance except for the bottom, effectively preventing dust or oil from entering the gaps. Through the cooperation of a transparent soft shell, support block, screw, matching nut, bracket, lifting plate, telescopic rod, and locking ring, the anti-accidental touch cover has a lifting function. Continuous pressure must be applied to the cover to lower it, preventing accidental touches. Furthermore, the locking ring can be raised and lowered; after the anti-accidental touch cover is lowered, the locking ring unlocks the switch contact, allowing the switch contact to be touched through the transparent soft shell. This effectively solves the problem of oil contamination affecting the protective structure while still allowing the switch contact to function normally.
[0016] In summary, by pressing down the anti-accidental contact cover, the screw and matching nut work together to support the lifting and lowering of the cover, and also drive the locking ring to lift and lower, so that the switch contact is not blocked by the locking ring. This allows the switch contact to be pressed down at the transparent soft shell, effectively preventing oil and dust from getting in.
[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4As shown, this utility model is an anti-accidental-touch emergency stop interlocking switch, including a switch body 1. A switch contact 6 is disposed inside the switch body 1. An anti-accidental-touch cover 2 is disposed on the outer side of the switch body 1. A transparent soft shell 3 is fixedly installed on the inner wall of the anti-accidental-touch cover 2. Two sets of support blocks 7 are fixedly installed on the inner side wall of the anti-accidental-touch cover 2. Each set of support blocks 7 has a screw 12 disposed inside. A matching nut 13 is threaded onto the outer surface of each screw 12. A bracket 5 is fixedly installed on the outer surface of each matching nut 13. The bottom surface of each bracket 5 is fixedly connected to the upper surface of the switch body 1. The outer surface of each screw 12 is threaded with a matching nut 13. A lifting plate 14 is provided, and two telescopic rods 11 are fixedly installed on the bottom surface of each lifting plate 14. The bottom surface of each telescopic rod 11 is fixedly connected to the upper surface of the switch body 1. A locking ring 8 is fixedly installed on one side of the four lifting plates 14 that are close to each other. The inner wall of the locking ring 8 is in contact with the outer surface of the switch contact 6. In this embodiment, by providing the lifting plate 14, telescopic rods 11 and locking ring 8, the lifting and lowering are synchronized with the lifting and lowering of the anti-accidental contact cover 2. After the locking ring 8 descends, the switch contact 6 can be pressed down normally. If the locking ring 8 does not descend, the switch contact 6 cannot be pressed down to avoid accidental contact.
[0028] The upper surface of the switch body 1 is provided with two sets of sockets 4, each set of sockets 4 being located directly below the screw 12. In this embodiment, the sockets 4 provide space for the screw 12 to descend, and the depth of the sockets 4 can be used to limit the descending height of the screw 12.
[0029] Each support block 7 has two disassembly pins 10 threadedly connected to its inner wall. The outer surface of each disassembly pin 10 is threadedly connected to the inner wall of the anti-accidental contact cover 2. In this embodiment, the disassembly pins 10 serve to connect the support block 7 and the anti-accidental contact cover 2 and are used to fix the support block 7.
[0030] Each support block 7 has a bearing 9 fixedly installed on its inner wall, and the inner wall of each bearing 9 is fixedly connected to the outer surface of the screw 12. In this embodiment, the screw 12 is fixed by the bearing 9, and the rotation of the inner ring of the bearing 9 can support the rotation of the screw 12.
[0031] Each lifting plate 14 has a connecting pressure plate 15 fixedly installed on its upper surface. The upper surface of each connecting pressure plate 15 is fixedly connected to the bottom surface of the support block 7. In this embodiment, the connecting pressure plate 15 is used to connect the lifting plate 14 and the support block 7, so that the lifting plate 14 can be pressed down during the descent of the support block 7.
[0032] Each lifting plate 14 has a through hole 16 on its upper surface, and each screw 12 passes through the through hole 16. In this embodiment, by providing the through hole 16, the screw 12 needs to pass through the lifting plate 14 without contacting the lifting plate 14, and the through hole 16 provides space for the screw 12 to pass through.
[0033] Understandably, firstly, it is necessary to continuously press the anti-accidental contact cover 2. During the descent of the anti-accidental contact cover 2, the screw 12 works with the matching nut 13 to drive the screw 12 down. Secondly, during the descent of the support block 7, the connecting pressure plate 15 drives the lifting plate 14 down, and then the lifting plate 14 drives the locking ring 8 down. The locking ring 8 is no longer fixing the switch contact 6. Finally, the switch contact 6 can be touched at the transparent soft shell 3 to turn the switch on and off.
[0034] One specific application of this embodiment is as follows: When using the switch body 1, to prevent accidental contact of the switch body 1, the anti-accidental contact cover 2 can perform normal anti-accidental contact. Furthermore, the opening of the anti-accidental contact cover 2 faces downwards, making it difficult for oil or dust to enter the contact switch contact 6. Since the anti-accidental contact cover 2 is integrated with the transparent soft shell 3, oil or dust cannot enter the interior of the anti-accidental contact cover 2. When the switch contact 6 needs to be used, the anti-accidental contact cover 2 can be continuously pressed down. Due to the transmission method of the screw 12 and the matching nut 13, there will be no sudden pressure drop. When the screw 12 is lowered, it needs to be pressed down continuously. The support block 7 and screw 12 will gradually descend. During the descent of the support block 7, the lifting plate 14 will be lowered through the connecting pressure plate 15. The lifting plate 14 will drive the locking ring 8 to descend. After the screw 12 descends into the insertion hole 4, the depth of the insertion hole 4 determines the overall descent height of the anti-accidental contact cover 2. After the anti-accidental contact cover 2 stops descending, the locking ring 8 will descend to the bottom of the switch contact 6. At this time, the locking ring 8 no longer supports the switch contact 6, and the switch contact 6 can be pressed normally. The switch contact 6 can be pressed at the transparent soft shell 3.
