Description

Technical Field

[0001] The utility model relates to the technical field of remote controllers, in particular to an explosion-proof remote controller. Background Art

[0002] In industrial environments, explosion-proof performance is crucial, especially in workplaces with flammable gas or dust environments. In order to ensure the safety of the remote control in these environments, we have adopted strict explosion-proof design standards. First, the shell material of the remote control is made of high-strength, corrosion-resistant explosion-proof material, which can effectively prevent the intrusion of external substances. Secondly, explosion-proof sealing design is adopted in key parts to ensure that the circuit inside the equipment will not explode due to sparks or high temperatures in extreme environments. In addition, the remote control is equipped with an explosion-proof safety isolation fence, which can effectively isolate the circuit, prevent the spread of sparks or arcs, and ensure the safety of equipment and operators.

[0003] When vibration occurs in existing explosion-proof remote controls, since there is a battery inside, if the circuit remains connected during vibration, then in extreme cases, such as an explosion, sparks may be generated in the circuit, which may further ignite surrounding flammable gases or dust, thereby causing the remote control to explode, posing a serious threat to personnel and the surrounding environment. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an explosion-proof remote control to solve the technical problem that sparks may be generated in the circuit and thus cause the explosion of the remote control.

[0005] To achieve the above object, the utility model provides the following technical solutions: an explosion-proof remote control, comprising a shell, wherein a first mounting wall and a second mounting wall are fixedly connected inside the shell, a mounting groove is provided on the first mounting wall, a conductive plate is rotatably connected to the mounting groove through a rotating shaft, a connecting plate is fixedly connected to one side of the conductive plate, and a spring is provided between the connecting plate and the first mounting wall;

[0006] A ball rod is engaged on one side of the conductive plate, a ball is fixedly connected to one end of the ball rod, limiting spring plates are engaged on the upper and lower sides of the ball, the limiting spring plates are fixedly connected to the first mounting wall, a pull rod is fixedly connected to the left side of the ball, and a shift rod is connected to one side of the pull rod through a ball joint.

[0007] By adopting the above technical solution, when the remote control housing is subjected to external impact or vibration, this force will be transmitted to the limiting spring pieces through the first mounting wall. Due to the elastic characteristics of the limiting spring pieces, they will be deformed or displaced, so that the card ball that was originally tightly clamped by them can be detached, thereby achieving rapid and reliable disconnection of the circuit, effectively preventing sparks that may be generated by short circuits in the circuit in explosion or extreme vibration environments, thereby significantly reducing the risk of explosion of the remote control itself.

[0008] Furthermore, a shock absorbing block is fixedly connected to the first installation wall, a slot is provided on the shock absorbing block, and the material of the shock absorbing block is rubber.

[0009] By adopting the above technical solution, the added shock-absorbing block can effectively absorb and disperse the impact of external impact or vibration on the internal structure of the remote control. Since the shock-absorbing block is made of rubber, it has good elasticity and buffering properties. When the outer shell is subjected to external force, the rubber shock-absorbing block can deform, thereby absorbing part of the impact energy, which helps to protect the internal structure of the remote control from damage and improve the durability and reliability of the equipment.

[0010] Furthermore, a third mounting wall is provided between the first mounting wall and the second mounting wall, and a battery is provided inside the third mounting wall.

[0011] By adopting the above technical solution, since the battery is placed inside the third mounting wall between the first mounting wall and the second mounting wall, it is fully protected, reducing the risk of damage under external impact or vibration, helping to ensure the stability and reliability of the battery under normal operation or extreme conditions, thereby extending the battery life.

[0012] Furthermore, a first conductive sheet is fixedly connected to one side of the third installation wall, and two first conductive sheets are provided, and the two first conductive sheets are arranged in a mirror image structure.

[0013] By adopting the above technical solution, the two conductive sheets are designed mainly to form a circuit loop. In the circuit, the current needs to flow from the positive electrode to the negative electrode to form a complete loop in order for the electrical equipment to work normally.

[0014] Furthermore, a second conductive sheet is fixedly connected to one side of the conductive plate, and two second conductive sheets are provided, and the two second conductive sheets and the two first conductive sheets are arranged opposite to each other.

[0015] By adopting the above technical solution, the setting of the second conductive sheet realizes electrical connection with the first conductive sheet, thereby completing the circuit loop. When the conductive plate is in a closed state, the second conductive sheet is in close contact with the corresponding first conductive sheet, ensuring that the current can pass smoothly, thereby providing the necessary circuit conditions for the normal operation of the explosion-proof remote control.

[0016] Furthermore, a plurality of the shock absorbing blocks are provided, and the plurality of the shock absorbing blocks are arranged in a rectangular array.

[0017] By adopting the above technical solution, the setting of multiple shock-absorbing blocks can more effectively absorb and disperse the impact of external impact or vibration on the internal structure of the remote control. When the outer shell is subjected to external forces, these shock-absorbing blocks arranged in a rectangular array can work together to disperse the impact energy to a larger area, thereby reducing its transmission to the internal circuit, thereby improving the durability and reliability of the device.

[0018] Furthermore, a bottom plate is fixedly connected to the rear side of the shell, and the bottom plate is adapted to the shell.

[0019] By adopting the above technical solution, the bottom plate is tightly connected and matched with the shell, which effectively increases the supporting area and strength of the bottom of the remote control, thereby improving the stability of the remote control.

[0020] Furthermore, a hand wheel is provided at the bottom of the front side of the housing, an eight-speed knob is provided above the hand wheel, a three-speed knob is provided above the eight-speed knob, and a power switch and an emergency stop button are provided above the three-speed knob.

[0021] By adopting the above technical solution, users can operate the explosion-proof remote control more conveniently and intuitively. The handwheel is a pulse electronic handwheel, and the output corresponds to 0-30000-60000; the gears on the eight-speed knob are off, x, y, z, a, b, c, 7 and the gears on the three-speed knob are x1, x10, x100, so that different gears can be selected according to specific needs to achieve precise control of the equipment; the power switch is used to control the power on and off of the remote control, so that the user can start or turn off the remote control at any time; and the emergency stop button can quickly cut off the power in an emergency to ensure the safe shutdown of the equipment.

[0022] Furthermore, a fixed spring sheet is engaged with the upper side of the locking ball, and a sliding spring sheet is engaged with the lower side of the locking ball. The sliding spring sheet is directly slidably connected to the first mounting wall.

[0023] By adopting the above technical solution, the setting of the fixed spring piece and the sliding spring piece further enhances the stability of the card ball in the limiting spring piece. The fixed spring piece is engaged with the upper side of the card ball, and the sliding spring piece is engaged with the lower side of the card ball and is slidably connected to the first mounting wall, which provides sufficient constraints for the card ball and limits its range of movement in the horizontal direction, thereby ensuring the accurate position of the card ball in the limiting spring piece.

[0024] Furthermore, an adjusting screw is provided between the fixed spring piece and the sliding spring piece.

[0025] By adopting the above technical solution, the setting of the adjusting screw makes the distance between the fixed spring piece and the sliding spring piece adjustable, and the clamping force of the fixed spring piece and the sliding spring piece on the stuck ball can be changed by adjusting the position of the adjusting screw, thereby achieving precise control of the force on the stuck ball, which helps to improve the service life of the equipment.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model provides a mounting groove, a conductive plate, a connecting plate, a spring and a third mounting wall, so that the explosion-proof remote control can respond quickly when facing the danger of explosion and effectively cut off the power supply, thereby protecting the safety of equipment and personnel;

[0028] 2. The utility model provides a shock-absorbing block. When the remote control is subjected to an accidental collision or impact, the shock-absorbing block can absorb part of the impact energy and disperse it to a larger area, thereby reducing the impact force transmitted to the internal equipment, which not only improves the safety and stability of the internal equipment, but also prolongs the service life of the equipment;

[0029] 3. The utility model provides an adjusting screw, a fixed spring piece and a sliding spring piece. When it is necessary to increase the clamping force, the adjusting screw only needs to be tightened appropriately to make the fixed spring piece and the sliding spring piece clamp the ball more tightly. Conversely, when it is necessary to reduce the clamping force, the adjusting screw can be loosened appropriately so that the user can flexibly adjust the clamping force of the fixed spring piece and the sliding spring piece on the ball according to actual conditions and needs.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0037] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1:

[0038] An explosion-proof remote control, such as Figure 1-Figure 5 As shown, it comprises a housing 1, a first mounting wall 2 and a second mounting wall 11 are fixedly connected inside the housing 1, a mounting groove 3 is provided on the first mounting wall 2, a conductive plate 4 is rotatably connected to the mounting groove 3 through a rotating shaft, a connecting plate 5 is fixedly connected to one side of the conductive plate 4, and a spring 6 is provided between the connecting plate 5 and the first mounting wall 2;

[0039] A ball rod 7 is engaged with one side of the conductive plate 4, and a ball 8 is fixedly connected to one end of the ball rod 7. Limiting spring pieces 9 are engaged on both the upper and lower sides of the ball 8. The limiting spring piece 9 is fixedly connected to the first mounting wall 2. A pull rod 27 is fixedly connected to the left side of the ball 8. One side of the pull rod 27 is connected to a lever 10 through a ball joint. When the remote control housing 1 is subjected to external impact or vibration, this force will be transmitted to the limiting spring piece 9 through the first mounting wall 2. Due to the elastic characteristics of the limiting spring piece 9, they will be deformed or displaced, so that the ball 8 that was originally tightly clamped by it can be detached, thereby realizing rapid and reliable disconnection of the circuit. Open, effectively preventing sparks that may be generated by short circuit in the circuit under explosion or extreme vibration environment, thereby significantly reducing the risk of explosion of the remote control itself. Once the circuit is disconnected, the user can restore the circuit connection by simply toggling the lever 10. The lever 10 is connected to the pull rod 27 through a ball joint, so its movement can easily drive the pull rod 27 to move. The movement of the pull rod 27 will then pull the card ball 8 back into the limiting spring piece 9, so that the remote control returns to normal working state. This not only allows the user to quickly restore the function of the remote control when necessary, but also enhances the operability and convenience of the device.

[0040] See also Figure 3 A shock absorbing block 12 is fixedly connected to the first mounting wall 2, and a card slot 13 is opened on the shock absorbing block 12. The material of the shock absorbing block 12 is rubber. The added shock absorbing block 12 can effectively absorb and disperse the influence of external impact or vibration on the internal structure of the remote control. Since the shock absorbing block 12 is made of rubber, it has good elasticity and buffering performance. When the shell 1 is subjected to external force, the rubber shock absorbing block 12 can be deformed, thereby absorbing part of the impact energy, which helps to protect the internal structure of the remote control from damage and improve the durability and reliability of the equipment. The card slot 13 on the shock absorbing block 12 is used to fix and install the circuit board, thereby realizing the functionality of the remote control.

[0041] See also Figure 3 A third mounting wall 14 is provided between the first mounting wall 2 and the second mounting wall 11, and a battery 15 is provided inside the third mounting wall 14. Since the battery 15 is placed inside the third mounting wall 14 between the first mounting wall 2 and the second mounting wall 11, it is fully protected, reducing the risk of damage under external impact or vibration, which helps to ensure the stability and reliability of the battery 15 under normal operation or extreme conditions, thereby extending the service life of the battery. Placing the battery 15 inside the third mounting wall 14 allows the remote control to maintain a compact size while achieving a reasonable layout of internal components, thereby improving the portability of the remote control.

[0042] See also Figure 4 A first conductive sheet 16 is fixedly connected to one side of the third mounting wall 14. Two first conductive sheets 16 are provided, and the two first conductive sheets 16 are arranged in a mirror structure. The two conductive sheets are designed mainly to form a circuit loop. In the circuit, the current needs to flow from the positive electrode to the negative electrode to form a complete loop in order for the electrical equipment to work normally. Therefore, two conductive sheets are provided in the explosion-proof remote control, which can be connected to the positive and negative electrodes of the battery respectively to form a circuit loop. In this way, when the battery is installed on the third mounting wall 14, the current can flow smoothly through the two conductive sheets to provide the required electrical energy for various components of the remote control.

[0043] See also Figure 4 A second conductive sheet 17 is fixedly connected to one side of the conductive plate 4. Two second conductive sheets 17 are provided. The two second conductive sheets 17 and the two first conductive sheets 16 are arranged opposite to each other. The arrangement of the second conductive sheet 17 realizes electrical connection with the first conductive sheet 16, thereby completing the circuit loop. When the conductive plate 4 is in a closed state, the second conductive sheet 17 is in close contact with the corresponding first conductive sheet 16 to ensure that the current can pass smoothly, providing the necessary circuit conditions for the normal operation of the explosion-proof remote control. The relative position of the two second conductive sheets 17 and the two first conductive sheets 16 makes the current more balanced during the transmission process, reduces the resistance and heat generation in the circuit, and thus reduces the risk of circuit failure.

[0044] See also Figure 3 There are multiple shock-absorbing blocks 12, and the multiple shock-absorbing blocks 12 are arranged in a rectangular array. The arrangement of the multiple shock-absorbing blocks 12 can more effectively absorb and disperse the impact of external impact or vibration on the internal structure of the remote control. When the shell 1 is subjected to external forces, these shock-absorbing blocks 12 arranged in a rectangular array can work together to disperse the impact energy to a larger area, thereby reducing its transmission to the internal circuit, improving the durability and reliability of the equipment, and the rectangular array arrangement of the shock-absorbing blocks 12 also helps to improve the structural stability of the remote control. This layout enables the shock-absorbing blocks 12 to provide support and constraints for the circuit board to form a stable overall structure.

[0045] See also Figure 2 A bottom plate 18 is fixedly connected to the rear side of the housing 1, and the bottom plate 18 is adapted to the housing 1. The bottom plate 18 is tightly connected and adapted to the housing 1, which effectively increases the supporting area and strength of the bottom of the remote control, thereby improving the stability of the remote control 1. In some cases, such as when the remote control accidentally falls or is hit, the bottom plate 18 can serve as the first layer of protection structure to absorb part of the impact energy and disperse the impact force, thereby reducing damage to the internal components of the remote control.

[0046] See also Figure 1 A hand wheel 19 is arranged at the bottom of the front side of the housing 1, an eight-speed knob 20 is arranged above the hand wheel 19, a three-speed knob 21 is arranged above the eight-speed knob 20, and a power switch 22 and an emergency stop button 23 are arranged above the three-speed knob 21, so that the user can operate the explosion-proof remote control more conveniently and intuitively. The hand wheel 19 is a pulse electronic hand wheel, and the output corresponds to 0-30000-60000; the gear positions on the eight-speed knob 20 are off, x, y, z, a, b, c, 7 and the gear positions on the three-speed knob 21 are x1, x10, x100, so that different gear positions can be selected according to specific needs to achieve precise control of the device; the power switch 22 is used to control the power on and off of the remote control, so that the user can start or turn off the remote control at any time; and the emergency stop button 23 can quickly cut off the power supply in an emergency to ensure the safe shutdown of the equipment, so that the user can easily touch and accurately operate each component during operation.

[0047] The implementation principle of the utility model is as follows: first, when an explosion occurs, the vibration is transmitted to the limit spring piece 9, causing the limit spring piece 9 to vibrate, so that the internally engaged ball 8 is separated from the spring piece 9. At this time, under the elastic force of the spring 6, the spring 6 pushes the connecting plate 5 to move, thereby driving the conductive plate 4 to rotate around the axis. At this time, the second conductive sheet 17 and the first conductive sheet 16 are separated, and the circuit is disconnected, thereby preventing the battery explosion caused by the internal circuit short circuit during the explosion;

[0048] When resetting is required, the lever 10 is moved, the lever 10 drives the pull rod 27 , and the pull rod 27 drives the locking ball 8 to be locked back into the limiting spring piece 9 . Embodiment 2:

[0049] See also Figure 5 The upper side of the card ball 8 is engaged with a fixed spring piece 24, and the lower side of the card ball 8 is engaged with a sliding spring piece 25. The sliding spring piece 25 is directly slidably connected to the first mounting wall 2. The setting of the fixed spring piece 24 and the sliding spring piece 25 further enhances the stability of the card ball 8 in the limiting spring piece 9. The fixed spring piece 24 is engaged with the upper side of the card ball 8, and the sliding spring piece 25 is engaged with the lower side of the card ball 8 and is slidably connected to the first mounting wall 2, which provides sufficient constraints for the card ball 8 and limits its range of movement in the horizontal direction, thereby ensuring the accurate position of the card ball 8 in the limiting spring piece 9, so that the sliding spring piece 25 can be slidably adjusted when needed, and then when the fixed spring piece 24 and the sliding spring piece 25 are worn, they can maintain sufficient tightness through adjustment.

[0050] See also Figure 5 An adjusting screw 26 is arranged between the fixed spring piece 24 and the sliding spring piece 25. The arrangement of the adjusting screw 26 makes the spacing between the fixed spring piece 24 and the sliding spring piece 25 adjustable. The clamping force of the fixed spring piece 24 and the sliding spring piece 25 on the card ball 8 can be changed by adjusting the position of the adjusting screw 26, thereby realizing precise control of the force on the card ball 8, which helps to improve the service life of the equipment. The existence of the adjusting screw 26 also provides convenience for the maintenance and debugging of the explosion-proof remote control. During long-term use, the fixed spring piece 24 and the sliding spring piece 25 may be deformed or loosened due to wear or aging. At this time, the clamping force of the fixed spring piece 24 and the sliding spring piece 25 on the card ball 8 can be easily restored by adjusting the position of the adjusting screw 26 without replacing the entire spring piece assembly, which not only reduces the maintenance cost but also improves the maintainability and service life of the equipment.

[0051] The implementation principle of the utility model is as follows: first, when the tightness of the fixed spring piece 24 needs to be adjusted, the adjusting screw 26 is rotated to allow the sliding spring piece 25 to slide up and down, thereby adjusting the locking force.
