Description

Technical Field

[0001] The utility model relates to the technical field of button boxes, in particular to an explosion-proof button box. Background Art

[0002] Explosion-proof push button boxes are used to control explosion-proof equipment in high-risk and explosive environments, and these devices also require explosion-proof push button boxes to control them. Due to the particularity of their working environment, explosion-proof push button boxes must have a high degree of safety and reliability.

[0003] In the Chinese utility model patent document with patent number "CN218866946U" and patent name: "An explosion-proof and corrosion-resistant control button assembly box", a technical solution is disclosed: a protective component is provided on the surface of the panel to protect the backup control panel. After the first control button and the second control button are damaged and fail, the backup control button below can be triggered by pressing the protective strip of the protective component hard, thereby performing emergency control of the connected equipment.

[0004] The above-mentioned technical solution has the following disadvantages: First, the backup control button is placed on the cover plate, and this design relies solely on the protective strip for protection. However, in the event that the panel is destroyed or damaged, this single protective strip cannot effectively protect the backup control button, causing the backup control button to fail. In addition, the protective strip itself is also susceptible to impact forces in accidents, causing it to bend or deform. Once such a problem occurs with the protective strip, it may accidentally touch the backup control button, and even when there is no emergency, it may mistakenly trigger the emergency control function of the device, increasing the risk of device operation and the potential failure rate.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The utility model provides a technical solution: an explosion-proof button box, comprising a box body 1, a box cover 3 fixedly assembled on the top of the box body 1 by fixing screws 2, the box body 1 and the box cover 3 are both cast from explosion-proof materials, have good explosion-proof effect, and are suitable for special operation environments, a first control button 4 and a second control button 5 are fixedly assembled on the surface of the box cover 3, and a mounting groove 6 is opened on the surface of the box cover 3, a spare control button 7 is fixedly assembled in the mounting groove 6, and a cover plate 8 is clamped in the mounting groove 6, the utility model installs the spare control button 7 in the mounting groove 6 with a hidden design, and protects it with the cover plate 8, thereby avoiding damage to the spare control button 7 and inability to press it in a safety accident, and also avoiding accidental touching of the spare control button 7 when an accident occurs.

[0019] The first control button 4, the second control button 5 and the backup control button 7 are respectively electrically connected to the control circuit board in the box body 1. The first control button 4, the second control button 5 and the backup control button 7 can send control signals to the control circuit board in the inner cavity of the explosion-proof box body 1, so that the control circuit board can perform emergency control such as powering off the connected external devices.

[0020] like Figure 1 and Figure 2 As shown in the figure, the side wall of the cover plate 8 is integrally formed with an arc-shaped card block 91, and the side wall of the mounting groove 6 is provided with an arc-shaped card slot 92 adapted to the arc-shaped card block 91. The cover plate 8 and the mounting groove 6 are detachably fixedly connected by the snap-fit ​​assembly 9 composed of the arc-shaped card block 91 and the arc-shaped card slot 92. When the spare control button 7 is needed, the cover plate 8 can be slid out of the mounting groove 6 in time to press the spare control button 7.

[0021] The surface of the cover plate 8 is uniformly and integrally formed with anti-skid patterns 10 , and the anti-skid patterns 10 can better facilitate the sliding operation of the cover plate 8 .

[0022] The side wall of the box body 1 is provided with a wire connection port 11 that communicates with the inner cavity. The wire connection port 11 is located away from the backup control button 7. Since the backup control button 7 is designed to be hidden and embedded in the mounting slot 6, the wire connection port 11 is placed at a distance from the mounting slot 6 to prevent the mounting slot 6 from interfering with the connection between the wires and the first control button 4 or the second control button 5.

[0023] like Figure 1 、 Figure 3 and Figure 4 As shown, the box body 1 is provided with mounting slots 12 at each of its four corners, with fixing components 13 embedded within these slots. The configuration of fixing components 13 facilitates the secure assembly of the box body 1 to the intended installation location. Fixing components 13 can be adjusted within the mounting slots 12 over short distances to accommodate varying installation conditions, ensuring a stable connection and fixation between fixing components 13 and the installation location.

[0024] The fixing assembly 13 includes a fixing frame 131, which is slidably connected to the assembly slot 12. A connecting shaft 132 that passes through the fixing frame 131 is fixedly assembled in the assembly slot 12. The number of the connecting shafts 132 is at least two, thereby increasing the stability of the connection and fixation between the fixing frame 131 and the box body 1. The fixing frame 131 can be adjusted in position along the connecting shaft 132 in the assembly slot 12, thereby being suitable for different installation environments. The side wall of the fixing frame 131 is provided with an assembly hole 133, and the assembly hole 133 is used for assembling a fixing bolt, thereby fixing the position of the fixing frame 131. The side wall of the fixing frame 131 is screwed with a fastening bolt 134. By setting the fastening bolt 134, the fixing frame 131 and the side wall of the box body 1 are clamped and fixed, thereby increasing the stability of the fixing frame 131 in fixing the installation position of the box body 1.

[0025] like Figure 4 As shown in the figure, the side wall of the fixing frame 131 is provided with a slot 135, and a rubber pad 136 is clamped in the slot 135. The rubber pad 136 is provided to enhance the stability between the fixing frame 131 and its fixed installation position. The rubber pad 136 can reduce the vibration between the fixing frame 131 and its installation position due to external reasons, thereby maintaining the stability of the structure between the fixing frame 131 and the installation position.

[0026] Working principle: During the use of the present invention, first tighten the fastening bolt 134 so that it no longer tightens the position between the fixing frame 131 and the box body 1, then adjust the installation position of the fixing frame 131 according to the installation environment, insert the fixing bolt into the assembly hole 133 to fix the fixing frame 131, adjust the box body 1 to a suitable installation position, and then connect and fix the box body 1 and the fixing frame 131 through the fastening bolt 134, insert the connecting wire into the box body 1 from the wire connection port 11, and connect them to the first control button 4, the second control button 5 and the spare control button 7 respectively, after completing the wiring, fix the box cover 3 to the box body 1 by the fixing screw 2, during use, the first control button 4 and the second control button 5 can be used to control the connected equipment, if a safety accident occurs, after the first control button 4 and the second control button 5 are damaged, the cover 8 can be slid open, and the equipment can be controlled by the spare control button 7.
