Abstract
Description
Technical Field
[0001] This utility model belongs to the field of galvanized door technology, and in particular relates to a galvanized door equipped with a bottom support structure. Background Technology
[0002] Galvanized doors are steel doors coated with a layer of zinc. The zinc layer effectively prevents the steel from rusting and corroding, making it suitable for outdoor or industrial environments. Galvanized doors are generally connected to the door frame by hinges. Because galvanized doors are relatively heavy, prolonged use can cause the hinges to deform, leading to the door tilting and the bottom of the door rubbing against the ground. To ensure smooth operation of galvanized doors, we have designed a galvanized door with a bottom support structure. A rolling bottom support is installed at the bottom of the galvanized door to provide auxiliary support and effectively enhance stability. Utility Model Content
[0003] The purpose of this utility model is to provide a galvanized door equipped with a bottom support structure, which has the advantage of providing auxiliary support to the galvanized door by setting a rolling bottom support at the bottom of the galvanized door, thereby effectively enhancing the stability and solving the above-mentioned technical problems.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A galvanized door with a bottom support structure includes a galvanized door body. A cavity is opened at the bottom of the front side of the galvanized door body. A square threaded sleeve is installed in the inner cavity of the cavity. A threaded rod is threadedly connected to the inner cavity of the square threaded sleeve. A sleeve is rotatably connected to the bottom of the threaded rod. A ball head seat is slidably connected to the inner cavity of the sleeve. A rotatable ball is installed in the inner cavity of the ball head seat. A coarse spring is fixedly connected between the top of the ball head seat and the inner wall of the sleeve.
[0005] Preferably, the inner cavity of the cavity is detachably fitted with a cover, and both the inner cavity of the cover and the inner cavity of the cavity are provided with rectangular mounting cavities that are adapted to the square threaded sleeve.
[0006] Preferably, four screws are provided through the front side of the cover, and the screws pass through the cover and are threadedly connected to the inner wall of the cavity.
[0007] Preferably, a hexagonal rotating block is fixedly connected to the top of the threaded rod.
[0008] Preferably, the inner wall of the cavity and the inner wall of the cover are both adapted to and fit against the sleeve.
[0009] The beneficial effects of this utility model are: 1. This utility model involves placing a square threaded sleeve inside the cavity of the galvanized door. Depending on the height of the galvanized door from the ground, the threaded rod is rotated to move downwards, thereby driving the sleeve, ball head seat, and ball to move downwards until the ball touches the ground. At this point, the threaded rod is continued to be operated to put the coarse spring under stress. Then, the cover is installed to cover the inner cavity of the cavity, thus achieving the purpose of setting a rolling bottom support at the bottom of the galvanized door to provide auxiliary support for the galvanized door and effectively enhance its stability. 2. The present invention provides a force point for the user to operate the threaded rod by setting a hexagonal rotating block, which facilitates the operation of the threaded rod rotation. Attached Figure Description
[0010] The advantages of the present invention, as described above and / or in the following detailed description in conjunction with the accompanying drawings, will become clearer and more readily understood. These drawings are merely illustrative and do not limit the scope of the present invention. Figure 1 This is a schematic diagram of one embodiment of the present utility model; Figure 2 This is a three-dimensional disassembled schematic diagram of the galvanized door body and the cover according to one embodiment of the present utility model; Figure 3 This is a three-dimensional disassembled schematic diagram of a galvanized door body and a square threaded sleeve according to an embodiment of the present invention; Figure 4 This is a perspective view of a cover according to an embodiment of the present invention.
[0011] The attached diagram lists the components represented by each number as follows: 1. Galvanized door body; 2. Cavity; 3. Square threaded sleeve; 4. Threaded rod; 5. Sleeve; 6. Ball head seat; 7. Rolling ball; 8. Coarse spring; 9. Rectangular mounting cavity; 10. Cover; 11. Screw; 12. Hexagonal swivel block. Detailed Implementation
[0012] In the following description, embodiments of the galvanized door with a bottom support structure of the present invention will be described with reference to the accompanying drawings.
[0013] Figure 1-4This invention illustrates an embodiment of a galvanized door equipped with a bottom support structure. It includes a galvanized door body 1, a cavity 2 at the bottom of the front side of the galvanized door body 1, a square threaded sleeve 3 installed inside the cavity 2, and a threaded rod 4 threadedly connected to the inner cavity of the square threaded sleeve 3. A hexagonal rotating block 12 is fixedly connected to the top of the threaded rod 4. The hexagonal rotating block 12 provides a force point for the user to rotate the threaded rod 4, facilitating its rotation. A sleeve 5 is rotatably connected to the bottom of the threaded rod 4, and the inner cavity of the sleeve 5 is slidably connected to... There is a ball head seat 6, and a rotatable ball 7 is installed in the inner cavity of the ball head seat 6. A thick spring 8 is fixedly connected between the top of the ball head seat 6 and the inner wall of the sleeve 5. A cover 10 is detachably installed in the inner cavity of the cavity 2. The inner cavity of the cover 10 and the inner cavity of the cavity 2 are both provided with rectangular mounting cavities 9 that are adapted to the square threaded sleeve 3. The inner wall of the cavity 2 and the inner wall of the cover 10 are adapted to the sleeve 5 and fit against the sleeve 5. Four screws 11 are provided through the front side of the cover 10. The screws 11 pass through the cover 10 and are threadedly connected to the inner wall of the cavity 2.
[0014] Working principle: When using this utility model, the cover 10 is removed, and then the square threaded sleeve 3 is inserted into the rectangular mounting cavity 9 inside the cavity 2, so that the rectangular mounting cavity 9 is in a locked state. Then, the hexagonal rotating block 12 is operated to drive the threaded rod 4 to rotate. Because the square threaded sleeve 3 is fixed, the threaded rod 4 moves downward and rotates. The threaded rod 4 drives the sleeve 5, ball head seat 6 and rolling ball 7 to move downward until the rolling ball 7 touches the ground. Then, the threaded rod 4 is operated to rotate. Because the diameter of the coarse spring 8 is relatively large and the coils are relatively dense, the coarse spring 8 will undergo a small deformation, so that the rolling ball 7 can be stably supported. The contact with the ground can also provide a certain degree of cushioning. Then, the cover 10 is inserted into the cavity 2 and fixed by the screw 11 to limit the sleeve 5 and the square threaded sleeve 3, ensuring the stability of the sleeve 5 and the rolling ball 7.
[0015] In summary: This galvanized door equipped with a bottom support structure, by placing the square threaded sleeve 3 inside the cavity 2, and operating the threaded rod 4 to rotate according to the height of the galvanized door 1 above the ground, causes the threaded rod 4 to move downward, thereby driving the sleeve 5, ball head seat 6, and rolling ball 7 to move downward until the rolling ball 7 touches the ground. At this point, continuing to operate the threaded rod 4 causes the coarse spring 8 to be under stress. Then, the cover 10 is installed to cover the inner cavity of the cavity 2, thus achieving the purpose of setting a rolling bottom support at the bottom of the galvanized door to provide auxiliary support for the galvanized door and effectively enhance its stability.
