[0002] Civil defense doors are special doors designed to protect personnel from dangers such as explosions, nuclear radiation, and chemical gases. They are typically installed in underground protective engineering projects. The role of the spray painting rack is to assist in evenly spraying the surface of the civil defense door with rust-proof, corrosion-resistant, and aesthetically pleasing paint.

[0003] Currently, the location and height of some air defense door spray painting racks are fixed, making it inconvenient for workers to spray paint air defense doors of different heights and locations, resulting in poor convenience.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a spray painting rack for air-raid shelter doors in order to achieve a more practical purpose. Utility Model Content

[0020] Example: As attached Figure 1 To be continued Figure 3 As shown: This utility model provides a spray painting rack for a civil defense door, including a base 1. The bottom end of the base 1 has a first sliding groove 2. A support seat 3 is slidably installed in the first sliding groove 2. Both the first sliding groove 2 and the support seat 3 have square cross-sections, allowing the first sliding groove 2 to limit the movement of the support seat 3. A first driving assembly is installed in the first sliding groove 2 to drive the support seat 3 to move. A pair of first mounting seats 4 are symmetrically installed on both sides of the base 1. A pair of second sliding grooves 5 are provided on opposite sides of each pair of first mounting seats 4. A second slider 6 is slidably installed in each pair of second sliding grooves 5. The cross-section of the second slider 6 is square, so that the second slide groove 5 can limit the movement of the second slider 6. A standing frame 7 is installed between the pair of second sliders 6 to facilitate the worker to stand and spray paint. A connecting seat 8 is installed between the pair of first mounting seats 4. A mounting groove 9 is provided through one side of the connecting seat 8. A second drive component is installed in the pair of second slide grooves 5 and the mounting groove 9 to drive the movement of the second slider 6. A pair of casters 10 are installed at the bottom of the pair of first mounting seats 4. The casters 10 can be models with a brake function to facilitate the worker to push the paint spray frame.

[0021] Among them, the bottom of the support base 3 is equipped with an anti-slip pad 11 to increase the friction between the support base 3 and the ground and increase the overall stability of the paint spraying frame.

[0022] The first drive assembly includes a first screw 12, which is rotatably mounted in the first slide groove 2 via a bearing seat, and the first screw 12 passes through the top end of the support 3 and is threadedly connected to the support 3.

[0023] The top of the first slide 2 is equipped with a first motor 13, and the output end of the first motor 13 is connected to the first screw 12 via a coupling.

[0024] The first motor 13 drives the first screw 12 to rotate, and the support base 3 moves under the limiting action of the first slide groove 2.

[0025] The second drive assembly includes a pair of second screws 14, which are rotatably mounted in the second slide groove 5 via bearing seats. The second screws 14 pass through the upper and lower ends of the second slider 6 and are threadedly connected to the second slider 6. A pair of synchronous pulleys 15 are mounted at the bottom of the pair of second screws 14 at a position parallel to the mounting groove 9. A transmission belt 16 is installed between the pair of synchronous pulleys 15. The transmission belt 16 passes through the mounting groove 9 to connect the pair of synchronous pulleys 15, and the pair of synchronous pulleys 15 are connected by transmission belt 16.

[0026] Among them, a second motor 17 is installed at the bottom end of one of the pair of second slides 5, and the output end of the second motor 17 is connected to one of the pair of second screws 14 via a coupling.

[0027] The second motor 17 drives a second screw 14 to rotate. Under the transmission action of a pair of synchronous pulleys 15, the pair of second screws 14 rotate together. Then, under the limiting action of the second slide groove 5, the pair of second sliders 6 move simultaneously.

[0028] The top of the standing frame 7 is equipped with a protective frame 18, and a door panel 19 is installed on one side of the protective frame 18 via a hinge. The protective frame 18 can protect the staff above the standing frame 7, and the door panel 19 is fixed with a pin, making it convenient for staff to enter or leave the standing frame 7.

[0029] The working principle of this embodiment is as follows: When using the spray painting frame for the air-raid shelter door, the worker first pushes the spray painting frame to the position where the air-raid shelter door is placed. Then, the first motor 13 and the second motor 17 are connected to an external power source and the first motor 13 is turned on. The first motor 13 drives the first screw 12 to rotate. Under the limiting action of the first slide groove 2, the support seat 3 moves downward and supports the ground. Then, the worker opens the door panel 19 and enters the standing frame 7 to carry out the spray painting operation through the spray gun. During the spraying process, the worker can turn on the second motor 17. The second motor 17 drives a second screw 14 to rotate. Under the transmission action of a pair of synchronous pulleys 15, the pair of second screws 14 rotate together. Then, under the limiting action of the second slide groove 5, the pair of second sliders 6 move up and down at the same time, so as to facilitate spraying at different height positions of the air-raid shelter door.

[0030] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
