Technical Field

[0001] This utility model relates to the technical field of signal control boxes, specifically a signal transmission control box. Background Technology

[0002] Signal transmission control boxes, as key relay and signal processing units, play a vital role in modern technological systems. They are widely used in various fields, including industrial automation, intelligent buildings, communication base stations, and various electronic equipment systems. The main function of a signal transmission control box is to condition, distribute, convert, or isolate input and output electrical signals. These processing steps aim to optimize the signal transmission process, ensuring the stability and reliability of signal transmission, thereby guaranteeing the efficient and accurate operation of each system.

[0003] The existing technology has the following shortcomings: The existing technology disclosed in CN218300503U discloses a machine tool signal transmission control box, which "includes a box body, a control circuit board, a plurality of aviation plugs, a signal output interface and a power supply interface. The control circuit board is installed in the box body, the plurality of aviation plugs are arranged in a matrix on the control circuit board, the box body is provided with openings corresponding to the plurality of aviation plugs, the signal output interface and the power supply interface are located on one side of the control circuit board, the side of the box body is provided with openings corresponding to the signal output interface and the power supply interface, the control circuit board includes a control chip, the plurality of aviation plugs are connected to the signal input pins of the control chip, and the signal output interface is connected to the signal output pins of the control chip"; The aforementioned signal control box uses bolts to seal the connection between the upper box and the base plate during use. However, when a fault occurs inside the control box and needs to be repaired or replaced, operators must use special tools to disassemble multiple bolts one by one. This process is cumbersome and time-consuming, greatly reducing maintenance efficiency. This problem is particularly prominent in situations with limited space or where frequent maintenance is required. Furthermore, bolts are prone to stripping, corrosion, or loss during repeated disassembly and assembly, affecting the reusability of the equipment and increasing maintenance costs. At the same time, the existing control boxes mostly use simple plug-in ports for their wire interfaces, which are prone to loosening or even falling off under external pulling or equipment vibration, causing signal interruption. In addition, there are gaps between the ports and the wires, resulting in unsatisfactory dustproof and waterproof effects. Utility Model Content

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] This utility model provides a technical solution: such as Figure 1 and Figure 2 As shown in this embodiment, a signal transmission control box includes a box body 1. The side wall of the box body 1 has a connection port, and the top of the box body 1 has an opening for storing and fixing structures such as control circuit boards. The control circuit board is disposed inside the box body 1. A connection component is disposed on the top of the box body 1 for quick assembly and disassembly between the box body 1 and the cover plate 2. A fixing component is disposed on the side wall of the box body 1 for fixing and sealing wires.

[0018] like Figure 3 and Figure 4 As shown, the connecting assembly includes a cover plate 2 and multiple sets of fixing holes 3. The cover plate 2 is located on the top of the box body 1 and is used to seal the top opening of the box body 1. The multiple sets of fixing holes 3 are symmetrically opened on the inner wall of the box body 1. Two sets of sealing strips 4 are symmetrically installed on the bottom of the cover plate 2. Multiple sets of limiting cylinders 5 are evenly distributed on the side wall of the sealing strips 4 to limit the movement of the fixing pins 6 and ensure the horizontal movement of the fixing pins 6. The fixing pins 6 are installed inside the limiting cylinders 5 for installation and fixation between the cover plate 2 and the box body 1. A connecting plate 7 is installed at the end of the fixing pin 6. The cover plate 2 is correspondingly set to the box body 1. The sealing strips 4 are attached to the inner wall of the box body 1. The fixing pins 6 are correspondingly set to the fixing holes 3. A return spring 8 is installed on the side wall of the connecting plate 7. A fixing piece 9 is installed at the end of the return spring 8. The fixing piece 9 is connected to the bottom of the cover plate 2. A connecting rope 10 is installed on the side wall of the connecting plate 7 for connecting the connecting plate 7. The connecting rope 10 passes through the fixing plate 9 and is pulled. A winding rod 11 is installed at the end of the connecting rope 10 and extends out of the cover plate 2. When the cover plate 2 needs to be disassembled, the user only needs to rotate the winding rod 11. The rotation of the winding rod 11 causes the connecting rope 10 to be wound and pulled. The pull of the connecting rope 10 causes the connecting plate 7 to move. The movement of the connecting plate 7 causes the fixing pin 6 to move and the return spring 8 to be compressed. The fixing pin 6 moves out of the fixing hole 3, releasing the limitation between the cover plate 2 and the box body 1, and the cover plate 2 can be removed. This facilitates the user's inspection and maintenance of the internal structure of the box body 1. When installing the cover plate 2, simply rotate the winding rod 11, then place the cover plate 2 and the box body 1 together, and finally slowly release the winding rod 11. Under the return force of the return spring 8, the fixing pin 6 is reinserted into the fixing hole 3, thus completing the connection and fixation between the cover plate 2 and the box body 1. The operation is simple and the risk of damage is low.

[0019] like Figure 1 and Figure 5As shown, the fixing assembly includes two sets of fixing plates 12, which are installed on the side wall of the box body 1. A transmission screw 13 is rotatably installed inside the fixing plate 12. A rotating handle 14 is installed at the end of the transmission screw 13 for rotating the transmission screw 13. Two sets of screw nuts 15 are symmetrically sleeved on the outside of the transmission screw 13. A clamping strip 16 is installed on the side wall of the screw nut 15 for clamping and limiting the wire. Two sets of external threads are formed on the surface of the transmission screw 13, and the two sets of external threads are arranged in opposite directions. The screw nut 15 is slidably disposed with the side wall of the box body 1. A vertical rod 17 is installed at the bottom of the clamping strip 16. A compression plate 18 is installed at the end of the vertical rod 17 for compressing or drawing back the gas in the gas storage box 19. A gas storage box 19 is slidably sleeved on the outside of the compression plate 18 for storing the gas. The gas storage box 19 is connected to the side wall of the box body 1. A connecting rod is installed at the bottom of the gas storage box 19. The connecting pipe 20 has multiple sets of sealing airbag rings 21 installed at its end. The sealing airbag rings 21 are located inside the connection port and are used to seal the connection between the wire and the inner wall of the connection port. After the wire is inserted, the user rotates the handle 14 clockwise. The rotation of the handle 14 drives the transmission screw 13 to rotate. The rotation of the transmission screw 13 drives the two sets of screw nuts 15 to move closer to each other. The movement of the screw nuts 15 drives the pressure strip 16 to move, which can clamp and limit the wire. At the same time, the movement of the pressure strip 16 drives the vertical rod 17 to move. The movement of the vertical rod 17 drives the extrusion plate 18 to move. The movement of the extrusion plate 18 can squeeze the gas in the gas storage box 19 from the connecting pipe 20 into the sealing airbag ring 21, causing the sealing airbag ring 21 to expand. This can seal the connection between the port and the wire, achieving good dustproof and waterproof effects. At the same time, it can also limit the wire, reducing the risk of the wire loosening or even falling off under external force or equipment vibration.
