Description

Technical Field

[0001] This utility model relates to the field of explosion-proof button devices, and in particular to an explosion-proof button structure that is easy to install and disassemble quickly. Background Technology

[0002] In industrial production, where many hazardous environments contain flammable and explosive substances, the safe operation of equipment is of paramount importance. As a key control component, the ease of installation and maintenance of explosion-proof buttons directly impacts production efficiency. Traditional explosion-proof button structures often employ complex screw fastening methods, requiring tools to tighten each screw individually during installation, a cumbersome and time-consuming process. Disassembly and maintenance also consume significant time to remove the screws, which are prone to stripping and damage during frequent operation. Furthermore, in hazardous environments, handling malfunctions quickly is crucial for ensuring safety. Therefore, there is an urgent need for an explosion-proof button structure that facilitates rapid installation and disassembly to address these challenges.

[0003] A search revealed Chinese patent publication number CN221407105U, which discloses an explosion-proof push button switch. The push button switch has a connecting base at its bottom, a sealing cover at the bottom of the connecting base, and multiple spring contacts evenly distributed on the outer side of the sealing cover. This utility model utilizes a spring and a pressing block to press against the outside of the sealing cover, thus facilitating connection and fixation during installation. An expansion bracket is mounted on the side of the spring and internally connected to a pressure ring. The pressure ring allows multiple expansion brackets to slide downwards. The expansion brackets are angled, and the downward pressure of the pressure ring causes deformation at the bending position of the spring. Simultaneously, the damping spring retracts, separating the pressing block from the outside of the sealing cover, achieving effective and quick disassembly. During installation, simply pass the sealing cover through the inside of the pressure ring and press down; the pressing block springs back, fixing the sealing cover. However, in actual use, when installing the push-button switch, the lack of limiting and guiding mechanisms prevents it from reaching the optimal position after being snapped in, requiring excessive wiring for connection and resulting in resource waste. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an explosion-proof button structure that is easy to install and disassemble quickly, aiming to improve the problem that the existing technology lacks limiting and guiding functions, which prevents it from reaching the optimal position.

Connecting post holes are fixedly connected to the left and right sides of the bottom inner wall of the mounting box. A wiring hole plate is fixedly connected to adjacent sides of two connecting post holes. A compression fitting is threaded to the front and back sides of the inner wall of the wiring hole plate. The mounting box has recesses on both the left and right sides of its top. A button block is provided on the inner wall of the right recess, and an emergency brake button is provided on the inner wall of the left recess. A cross-shaped locking block is fixedly connected to the bottom of both the button block and the emergency brake button. A U-shaped plate is fixedly connected to the center of the top of the inner wall of the top cover. Multiple telescopic springs are fixedly connected to the left and right sides of the inner wall of the U-shaped plate. A trapezoidal locking block is fixedly connected to the other end of each of the multiple telescopic springs. The outer wall of the trapezoidal locking block engages with the inner wall of the cross-shaped locking block. A sealing mechanism is provided on the top of the top cover.

[0006] The above technical solution involves the following steps: When installing the explosion-proof button, first align the top cover with the top of the mounting box and initially position it using the connecting screws. Then, rotate the connecting screws to fix the top cover. The connecting hole post is used for positioning and connection, ensuring that the button block and emergency brake button are stably installed and connected to the circuit. The wiring hole plate is used to connect external wiring. The wire connection is secured by rotating and squeezing the screws. When replacing the button, the cross-shaped locking block passes through the notch and engages with the trapezoidal locking block. After being placed in the designated position, the trapezoidal locking block engages with the cross-shaped locking block. When disassembling, push the trapezoidal locking block to release the engagement, remove the button block and emergency brake button, and the installation is complete.

[0007] As a further description of the above technical solution: The sealing mechanism includes two limiting rings, the bottom ends of which are fixedly connected to the top left and right sides of the top cover, respectively. A sealing ring is fixedly connected to the top of the inner wall of the limiting ring. A transparent protective sleeve is fixedly connected to the top left side of the top cover. A transparent cover is rotatably connected to the rear side of the outer wall of the transparent protective sleeve. A rubber waterproof sleeve is threaded to the front side of the inner wall of the connecting tube. An annular baffle is fixedly connected to the top of the mounting box. The outer wall of the annular baffle engages with the inner wall of the top cover.

[0008] Through the above technical solution: when the top cover is installed on the mounting box, the limiting ring prevents sewage from entering, the sealing ring is squeezed and deformed to seal the tiny gaps between the top cover and the mounting box, preventing particles in dust and moisture from intruding, reducing the risk of short circuits or component corrosion, the transparent protective sleeve provides protection for the emergency braking button, the transparent cover can be opened for easy operation, and when closed, it forms a closed space with the protective sleeve, reducing the button's contact with the outside world and extending its service life, the rubber waterproof sleeve wraps the circuit, and the annular baffle forms a physical barrier between the mounting box and the top cover, enhancing the sealing effect and comprehensively improving the protective performance of the sealing mechanism.

[0009] As a further description of the above technical solution: The bottom left and right sides of the cross-shaped locking block are fixedly connected to contact posts, and the bottom end of the contact post engages with the inner wall of the connecting hole post.

[0010] The above technical solution allows for precise positioning of the cross-shaped locking block within the connecting hole post via the contact post, preventing the cross-shaped locking block from shaking or shifting during connection and ensuring the stability of the entire circuit connection. Furthermore, the bottom end of the contact post engages with the inner wall of the connecting hole post, providing a certain axial force to prevent the cross-shaped locking block from detaching from the connecting hole post axially during use.

[0011] As a further description of the above technical solution: Limiting strips are fixedly connected to the bottom front and rear sides of the inner wall of the U-shaped plate. The left and right sides of the outer wall of the limiting strips are slidably connected to the bottom of the trapezoidal block. A connecting post is fixedly connected to the front side of the trapezoidal block, and a concave block is fixedly connected to the front end of the connecting post.

[0012] The above technical solution allows the trapezoidal block to move back and forth within a certain range by means of a limiting strip, while ensuring that the trapezoidal block always moves within the limited track, preventing it from deviating or misaligning, and ensuring the normal operation of the relevant mechanical structure. The connecting column can tightly connect the trapezoidal block and the concave block together, and the concave block can easily push the trapezoidal block to release it from the cross block.

[0013] As a further description of the above technical solution: A nameplate is fixedly connected to the front end of the top of the top cover, and a warning sign block is fixedly connected to the rear end of the top of the top cover.

[0014] The above technical solutions enable the rapid and accurate acquisition of this important information through nameplates, thereby ensuring the correct use and effective management of equipment. Warning signs can serve as a strong warning to those in the vicinity, preventing accidents caused by misoperation or proximity, and effectively ensuring the safety of the working environment.

[0015] As a further description of the above technical solution: Both the transparent cover and the outer wall of the transparent protective sleeve are fixedly connected with perforated blocks, and a status light is fixedly connected to the top right end of the top cover.

[0016] The above technical solution allows for easy locking of the transparent cover and protective sleeve using a perforated block, while status lights display the current operating status of the device.

[0017] As a further description of the above technical solution: The four corners of the top of the inner wall of the mounting box are threaded with fastening screws. The outer wall of the fastening screw is provided with a hollow block, and the inner wall of the hollow block engages with the outer wall of the fastening screw.

[0018] The above technical solution allows for the use of fastening screws to securely fasten the mounting box and the hollow block together, while the hollow block facilitates the installation of equipment.

[0019] As a further description of the above technical solution: A silicone cushioning pad is fixedly connected to the top center of the inner wall of the mounting box, and multiple corrugated anti-slip grooves are opened at the bottom of the silicone cushioning pad.

[0020] The above technical solution effectively absorbs and buffers these impact forces through the silicone buffer pad, reducing damage to the precision components inside the mounting box. The corrugated anti-slip groove increases the friction between the silicone buffer pad and the components placed on it, preventing the components from sliding inside the mounting box and further ensuring the stability of the internal structure of the equipment.

[0021] This utility model has the following beneficial effects: 1.

Simultaneously, the sealing ring 202 fills the tiny gaps between the top cover 3, the button block 10, and the emergency brake button 11, effectively preventing dust and small particles in moisture from entering through the connection between the top cover 3 and the mounting box 1. This reduces the risk of short circuits or component corrosion caused by external impurities. The transparent protective cover 203 provides primary protection for the emergency brake button 11. Under normal operating conditions, the transparent cover 204 can be opened to allow operators to press the button. When not in use or in harsh environments, the transparent cover 204 is closed, forming a relatively enclosed space together with the transparent protective sleeve 203, further isolating dust and moisture, reducing direct contact between the buttons and the external environment, thereby extending the lifespan of the buttons. The rubber waterproof sleeve 205 can tightly wrap the circuit, while the annular baffle 206 forms a physical barrier between the mounting box 1 and the top cover 3, further enhancing the sealing effect. It can not only prevent foreign objects from laterally intruding from the gap between the mounting box 1 and the top cover 3, but also play a preliminary positioning role during the installation of the top cover 3, thereby comprehensively improving the protective performance of the sealing mechanism 2.
