[0001] This utility model belongs to the field of emergency stop switch technology, specifically relating to an emergency stop switch protection mechanism for belt conveyors to prevent tearing. Background Technology

[0002] As a key component of master control electrical appliances, the emergency stop switch is mainly used to quickly cut off the power supply when equipment enters a dangerous state, ensuring the safety of personnel and equipment. Its core function is achieved through series connection to the control circuit, and operation is primarily manual pressing, typically featuring a red mushroom-shaped button with a locking mechanism. Depending on the application scenario, this device features IP65 protection rating, modular design, and other characteristics, making it adaptable to harsh industrial environments.

[0003] However, existing emergency stop switches often lack an automatically pop-up protective cover, requiring manual lifting of the cover when opening the emergency stop switch, causing inconvenience during use. Furthermore, existing emergency stop switches often lack a sealable protective cover, allowing dust and other contaminants to easily enter the emergency stop switch, reducing its service life. Therefore, there is an urgent need for a tear-resistant emergency stop switch protection mechanism for belt conveyors to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a protective mechanism for an emergency stop switch for belt conveyors to prevent tearing, so as to solve the problems mentioned in the background art that existing emergency stop switches often do not have a protective cover that can automatically pop up, which makes it necessary to manually lift the protective cover when opening the emergency stop switch, and existing emergency stop switches often do not have a protective cover that can be sealed, which makes it easy for dust and other substances to enter the emergency stop switch.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a belt conveyor anti-tear emergency stop switch protection mechanism, comprising a base, an emergency stop switch body, a protective cover, a rotating structure, and a pressing plate. The top of the base is fixedly connected to the emergency stop switch body, and a sealing ring is fixedly connected to the top of the base. The rotating structure is provided in two sets. The rear end of the protective cover is rotatably connected to the base through the rotating structure, and the front side of the base is rotatably connected to the pressing plate through the rotating structure. A buckle is fixedly connected to the front side of the protective cover, and a buckle is fixedly connected to the rear side of the pressing plate. The rotating structure includes a fixed seat, two fixed seats are rotatably connected to a rotating shaft, and a fixed seat is rotatably connected to the middle of the rotating shaft.

[0006] Preferably, the shape and size of the first sealing ring correspond to that of the second sealing ring, and the top surface of the first sealing ring and the bottom surface of the second sealing ring are all provided with serrations, and the first sealing ring and the second sealing ring mesh with each other.

[0007] Preferably, the first fixing seat is fixedly connected to the first limiting plate on the side closer to the center, and the second fixing seat is fixedly connected to the second limiting plate on the side farther from the center.

[0008] Preferably, torsion springs are fitted at both ends of the rotating shaft, with one end of the torsion spring abutting against the first limiting plate and the other end of the torsion spring abutting against the second limiting plate.

[0009] Preferably, one of the two fixed seats of the rotating structure is fixedly connected to the top of the base, and the other fixed seat is fixedly connected to the rear side of the protective cover.

[0010] Preferably, the other set of rotating structures has a fixed base one fixedly connected to the front side of the base, and a fixed base two fixedly connected to the rear side of the pressing plate.

[0011] Preferably, the front side of the pressing plate is provided with an anti-slip coating.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This emergency stop switch protection mechanism for belt conveyors is equipped with a rotating structure and a pressing plate. When the emergency stop switch body needs to be used, pressing the lower end of the pressing plate causes the pressing plate to rotate the fixed seat two. The limiting plate two compresses the torsion spring, causing the torsion spring to deform under pressure, making the upper end of the pressing plate lift up, so that the second buckle no longer engages with the first buckle. At this time, the spring force of the rotating structure at the rear end of the protective cover pushes the limiting plate two, causing the limiting plate two to rotate the fixed seat two, making the protective cover lift up. At this time, the button of the emergency stop switch body can be pressed. When the protective cover needs to be closed, closing the protective cover causes the first buckle to compress the second buckle, causing the second buckle to move forward. When the protective cover is completely closed, the spring force of the torsion spring pushes the pressing plate to reset, making the second buckle engage with the first buckle. Through the cooperation of the rotating structure and the pressing plate, the protective cover can be installed and fixed, and it is easy to open quickly. The operation is convenient and quick, and it is easy to use.

[0014] 2. The emergency stop switch protection mechanism for belt conveyors is equipped with a sealing ring one and a sealing ring two. When the protective cover is placed on the base, the sealing ring two engages with the sealing ring one, and the sealing ring one and the sealing ring two mesh with each other, thereby sealing the inside of the protective cover. The sealing performance of the emergency stop switch body can be improved by the sealing ring one and the sealing ring two, reducing the possibility of impurities, dust and moisture in the air entering the emergency stop switch body. This not only improves the service life of the emergency stop switch and reduces the risk of short circuit, but also enhances the protection of personal and equipment safety.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-5 This utility model provides an embodiment of an emergency stop switch protection mechanism for belt conveyors to prevent tearing. It includes a base 1, an emergency stop switch body 2, a protective cover 3, a rotating structure 4, and a pressing plate 5. The emergency stop switch body 2 is fixedly connected to the top of the base 1, and a sealing ring 11 is fixedly connected to the top of the base 1. The rotating structure 4 has two sets. The rear end of the protective cover 3 is rotatably connected to the base 1 via the rotating structure 4, and the front side of the base 1 is rotatably connected to the pressing plate 5 via the rotating structure 4. A buckle 32 is fixedly connected to the front side of the protective cover 3, and a buckle 51 is fixedly connected to the rear side of the pressing plate 5. The rotating structure 4 includes a fixing seat 41, two fixing seats 41 are rotatably connected to a rotating shaft 43, and a fixing seat 44 is rotatably connected to the middle of the rotating shaft 43. Through the cooperation of the rotating structure 4 and the pressing plate 5, the protective cover 3 can be installed and fixed, and it is easy to open quickly, making operation convenient and quick, and easy to use.

[0023] Furthermore, the shape and size of sealing ring 11 correspond to those of sealing ring 31. Both the top and bottom surfaces of sealing ring 11 and sealing ring 31 are serrated, and sealing ring 11 and sealing ring 31 mesh with each other. When the protective cover 3 is placed on the base 1, sealing ring 31 is engaged with sealing ring 11. The meshing of sealing ring 11 and sealing ring 31 seals the inside of the protective cover 3. The sealing performance of the emergency stop switch body 2 is improved by sealing ring 11 and sealing ring 31, reducing the possibility of impurities, dust and moisture in the air entering the emergency stop switch body 2. This not only improves the service life of the emergency stop switch and reduces the risk of short circuit, but also enhances the protection of personal and equipment safety.

[0024] Furthermore, a limiting plate 42 is fixedly connected to the side of the first fixed seat 41 near the middle, and a limiting plate 45 is fixedly connected to the side of the second fixed seat 44 away from the middle. Both ends of the rotating shaft 43 are fitted with torsion springs 46. One end of the torsion spring 46 abuts against the first limiting plate 42, and the other end of the torsion spring 46 abuts against the second limiting plate 45. By having the first limiting plate 42 and the second limiting plate 45 abut against the two ends of the torsion spring 46 respectively, the force of the torsion spring 46 can be applied to the first fixed seat 41 and the second fixed seat 44.

[0025] Furthermore, two fixed seats 41 of a set of rotating structures 4 are fixedly connected to the top of the base 1, and fixed seat 44 is fixedly connected to the rear side of the protective cover 3. The protective cover 3 and the base 1 are rotated relative to each other by a set of rotating structures 4, and the limit plate 45 is pushed by the spring force of the torsion spring 46, so that the limit plate 45 drives the fixed seat 44 to rotate, thereby lifting the protective cover 3.

[0026] Furthermore, the fixing seat 41 of another set of rotating structures 4 is fixedly connected to the front side of the base 1, and the fixing seat 44 is fixedly connected to the rear side of the pressing plate 5. The pressing plate 5 and the base 1 are rotated relative to each other through a set of rotating structures 4. When the protective cover 3 is completely closed, the elastic force of the torsion spring 46 pushes the pressing plate 5 to reset, so that the second buckle 51 engages with the first buckle 32.

[0027] Furthermore, the front side of the pressing plate 5 is provided with an anti-slip coating to prevent slippage when pressing the lower end of the pressing plate 5, making the pressing plate 5 easier to press.

[0028] Working principle: When using the emergency stop switch body 2, press the lower end of the press plate 5, causing the press plate 5 to rotate the fixed base 44. The limiting plate 45 compresses the torsion spring 46, causing the torsion spring 46 to deform under pressure, lifting the upper end of the press plate 5. This causes the latch 51 to no longer engage with the latch 32. At this time, the torsion spring 46 of the rotating structure 4 at the rear end of the protective cover 3 pushes the limiting plate 45, causing the limiting plate 45 to rotate the fixed base 44, lifting the protective cover 3. At this time, the button of the emergency stop switch body 2 can be pressed. When it is necessary to close the protective cover 3, close the protective cover 3, causing the latch 32 to compress the latch 51, causing the latch 51 to move forward. When the protective cover 3 is fully closed, the torsion spring 46... Forcefully push the pressing plate 5 to reset, causing the second buckle 51 to engage with the first buckle 32. Through the cooperation of the rotating structure 4 and the pressing plate 5, the protective cover 3 can be installed and fixed, and it is easy to open quickly. The operation is convenient and quick, and it is easy to use. When the protective cover 3 is placed on the base 1, the second sealing ring 31 engages with the first sealing ring 11. The first sealing ring 11 and the second sealing ring 31 mesh with each other, thereby sealing the inside of the protective cover 3. The sealing performance of the emergency stop switch body 2 can be improved through the first sealing ring 11 and the second sealing ring 31, reducing the possibility of impurities, dust and moisture in the air entering the emergency stop switch body 2. This not only improves the service life of the emergency stop switch and reduces the risk of short circuit, but also enhances the protection of personal and equipment safety.
