Description

Technical Field

[0001] This utility model relates to the field of display control device technology, specifically an external vacuum display control device. Background Technology

[0002] An external vacuum display and control device allows for the setting of internal equipment parameters. By changing these parameters, the operating environment of the equipment can be altered. Simultaneously, it enables users to monitor the vacuum index in real time and perform vacuum raising and lowering operations.

[0003] The reactive power compensation controller disclosed in the prior art, CN206575735U, has a heat sink located above the heat dissipation holes to prevent dust from falling into the heat dissipation holes. At the same time, the heat dissipation holes are located on the top of the outer casing, which makes the heat dissipation effect better. Both ends are flush with the sides of the outer casing. A heat dissipation hole is opened in the middle of the top of the outer casing below the heat sink. The heat dissipation hole communicates with the outside through the heat sink.

[0004] The cited document states that the vacuum display control device is cooled by heat dissipation holes and a heat sink. However, since the vacuum display control device is directly mounted on the equipment, the heat from the equipment is directly conducted to the vacuum display control device, so the heat dissipation effect of the heat sink and heat dissipation holes is relatively small. Summary of the Invention

[0005] The purpose of this invention is to provide an external vacuum display and control device to solve the problem mentioned in the background art of the current vacuum display and control devices on the market that cannot dissipate heat.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an external vacuum display and control device, comprising a display control cabinet, a limit ring, and a lifting rod;

[0007] A limit ring is rotatably connected to the top of the display control cabinet, and multiple lifting rods are provided on the top of the display control cabinet;

[0008] Also includes:

[0009] Three extrusion plates slide inside the limiting ring;

[0010] An internal airbag is installed on the outside of the lifting rod;

[0011] Water pipes are installed inside the lower part of the display control cabinet;

[0012] A fixing ring is disposed inside the limiting ring, and a fixing rod that drives the extrusion plate to move is slidably engaged inside the fixing ring;

[0013] The tube column is fixed inside the lower end of the display control cabinet, and a piston slides inside the tube column.

[0014] Preferably, the inner side of the limiting ring is movably connected to a connecting rod at an equal angle, and the other end of the connecting rod is movably connected to a fixed rod. The inner end of the extrusion plate is provided with an extrusion plate for further extrusion of the inner airbag. The display control cabinet is provided with a motor in the middle of the front side, and the output end of the motor is provided with a reciprocating screw. The moving rod moves up and down by rotating the reciprocating screw, thereby pulling the upper and lower ropes.

[0015] Preferably, the reciprocating screw is threadedly connected to a movable rod that pulls the upper and lower ropes. An upper rope is provided on the front side of the movable rod to move the piston, and a lower rope is provided below the movable rod. The piston inside is pulled by the upper and lower ropes, thereby pushing the water inside.

[0016] Preferably, the other ends of the lower rope and the upper rope are fixed to the two sides of the piston, and the end of the tubing is connected to the water pipe. The water pipe has an "S" shape, which increases the contact area and accelerates the cooling rate.

[0017] Preferably, the inside of the tubing is equipped with a condensation assembly, and both the inside of the tubing and the inside of the water pipe are filled with cooling water. The piston's movement distance is the same as the movement distance of the moving rod. The internal temperature is cooled by the cooling water, which protects the internal parts and increases their service life.

[0018] Preferably, the moving distance of the extrusion plate is greater than the distance between the extrusion plate and the inner airbag, the length of the connecting rod is the moving distance of the fixed rod, and the moving distance of the fixed rod is less than the distance from the rear end of the fixed rod to the outside of the fixed ring. The extrusion plate extrudes the inner airbag, thereby making the interior a sealed structure, preventing moisture from entering the lifting rod and preventing parts from rusting.

[0019] Preferably, the right end of the moving rod is engaged with a sliding rod, and both ends of the sliding rod are engaged with the inside right end of the display control cabinet. A display screen is installed on the upper left of the display control cabinet, thereby allowing the sliding rod and the moving rod to extend and retract.

[0020] Compared with the prior art, the beneficial effects of this utility model are: by moving the extrusion plate inward to compress the inner airbag, a sealing function is achieved, preventing moisture from entering the control device and protecting the internal components. Furthermore, the flow of water through the water pipe cools the display control cabinet, preventing aging and overload of internal components. The specific details are as follows:

[0021] 1. The rotation of the limit ring causes the extrusion plate to move and extrude the inner airbag. The inner airbag fills the gap between the lifting rod and the extrusion plate, thereby achieving a sealing function, preventing moisture from entering the interior of the display control cabinet, preventing the aging of internal parts, and protecting the internal parts.

[0022] 2. The piston moves to push the water inside, causing it to flow through the water pipes. This water flow absorbs heat from inside the display control cabinet, accelerating heat dissipation, protecting internal components, and extending the cabinet's lifespan. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-5 This utility model provides a technical solution: an external vacuum display control device, including a display control cabinet 1, a limiting ring 2, and lifting rods 3; the limiting ring 2 is rotatably connected to the top of the display control cabinet 1, and multiple lifting rods 3 are provided on the top of the display control cabinet 1;

[0031] Combination Figure 1 As shown, the internal adjustment of the display control cabinet 1 is achieved by adjusting the lifting rod 3. The lifting rod 3 is manually pushed. The system also includes: three extrusion plates 5 sliding inside the limiting ring 2; an inner airbag 4 installed on the outside of the lifting rod 3; a water pipe 9 located at the lower end of the display control cabinet 1; a fixing ring 7 located inside the limiting ring 2, with a fixing rod 6 that drives the extrusion plates 5 to move; a connecting rod 8 movably connected at an equal angle to the inside of the limiting ring 2, with the other end of the connecting rod 8 movably connected to the fixing rod 6; and an extrusion plate 5 at the inner end of the extrusion plate 5 that further extrudes the inner airbag 4; the inner airbag 4, which is sealed, passes through the outside of the lifting rod 3; the moving distance of the extrusion plate 5 is greater than the distance between the extrusion plate 5 and the inner airbag 4; the length of the connecting rod 8 is the moving distance of the fixing rod 6; and the moving distance of the fixing rod 6 is less than the distance from the rear end of the fixing rod 6 to the outside of the fixing ring 7.

[0032] Combination Figure 1-3 As shown, by manually rotating the limiting ring 2, the limiting ring 2 rotates and drives the connecting rod 8 to move. The connecting rod 8 pushes the fixed rod 6, and the fixed rod 6 drives the extrusion plate 5 to move inward. The extrusion plate 5 moves inward and extrudes the inner airbag 4, thereby deforming the inner airbag 4 to fit against the lifting rod 3, thus achieving the sealing function, preventing moisture from entering the interior of the display control cabinet 1, protecting the parts inside the display control cabinet 1, preventing the parts from rusting, and increasing the service life of the parts.

[0033] A motor 10 is located in the center of the front side inside the display control cabinet 1. A reciprocating screw 15 is installed at the output end of the motor 10. A moving rod 16, which pulls the upper rope 11 and the lower rope 12, is threaded onto the outer side of the reciprocating screw 15. An upper rope 11, which moves the piston 14, is located in front of the moving rod 16, and a lower rope 12 is located below the moving rod 16. The other ends of the lower rope 12 and the upper rope 11 are fixed to both sides of the piston 14. Water temperature control devices are installed at the upper front corner and the lower rear corner of the display control cabinet 1. A cooling tube column 13 is provided, and the end of the tube column 13 is connected to a water pipe 9, which has an "S" shaped structure. A piston 14 that pushes water is slidably engaged inside the tube column 13. Cooling water is provided inside both the tube column 13 and the water pipe 9. The moving distance of the piston 14 is the same as the moving distance of the moving rod 16. A sliding rod 18 is engaged at the right end of the moving rod 16. Both the left and right ends of the sliding rod 18 are engaged inside the right end of the display control cabinet 1. A display screen 17 is installed on the upper left of the display control cabinet 1.

[0034] Combination Figure 4-5As shown, when the power to the motor 10 is turned on, the motor 10 causes the reciprocating screw 15 to rotate. When the reciprocating screw 15 rotates, it causes the moving rod 16 to move downwards. This downward movement of the moving rod 16 moves the upper ropes 11 on both the upper left and right sides. The movement of the upper rope 11 on the right side causes the piston 14 at the lower rear corner to move to the left. The movement of the piston 14 at the lower rear corner pushes the water inside the pipe column 13, thus allowing water to enter the water pipe 9. Meanwhile, the upper rope 11 on the left side moves the piston 14 at the upper front corner, thus causing the water inside the water pipe 9 to... Water enters the interior of the upper front corner column 13 to cool the warm water. When the moving rod 16 moves upward, it pulls the lower ropes 12 on the left and right sides below. The lower rope 12 on the left pulls the piston 14 in the upper front corner, thereby allowing the water inside the upper front corner column 13 to enter the water pipe 9. The lower rope 12 on the right pulls the piston 14 in the lower rear corner, thereby allowing water to enter the interior of the lower rear corner column 13. The cooling water flow dissipates heat from the display control cabinet 1, improving the heat dissipation efficiency.

[0035] Working principle: When using this external vacuum display and control device, combined with... Figure 1-5 As shown, the piston 14 is pulled by the combined action of the upper rope 11 and the lower rope 12, thereby allowing water to enter the interior of the water pipe 9 to achieve the cooling function. The connecting rod 8 rotates to push the extrusion plate 5, thereby extruding the inner airbag 4 to achieve the sealing function, protecting the internal parts of the display control cabinet 1 and increasing the service life of the display control cabinet 1. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
