Specific implementation manners

[0027] Referring to Figures 1 to 4 shown, the present utility model provides a technical solution: a limiting bracket for steel door spraying, including a fixed plate 1, a rotating shaft 6 is rotatably connected to the upper surface of the fixed plate 1, the other end of the rotating shaft 6 is fixedly connected to a rotating frame 2, a steel door 3 abuts against the upper surface of the rotating frame 2, a clamping device 4 is arranged on the side surface of the rotating frame 2, and an auxiliary device 5 is sleeved on the upper surface of the fixed plate 1.

[0028] Next, specifically describe the specific settings and functions of its clamping device 4 and auxiliary device 5.

[0029] Referring to Figure 2 And Figure 3As shown in the figure, in this implementation: The clamping device 4 includes a screw 41 and a clamping plate 44. The arc surface of the screw 41 is threadedly connected to the inner wall of the rotating frame 2. On one side where the two screws 41 are close to each other, a moving plate 42 is rotatably connected. The cross-section of the moving plate 42 is in the shape of an "H". A rotating rod 43 threadedly penetrates through the inner wall of the end of the moving plate 42 away from the rotating shaft 6. Opposite-direction threads are provided on the arc surface of the rotating rod 43. A sliding rod 48 slidably penetrates through the inner wall of the other end of the moving plate 42. The inner wall of the side of the clamping plate 44 away from the sliding rod 48 is threadedly connected to the rotating rod 43, and the inner wall of the other side of the clamping plate 44 is slidably connected to the sliding rod 48. The cross-section of the clamping plate 44 is in the shape of a "U". By providing the clamping device 4, it is realized that the operator only needs to rotate the screw 41 and the rotating rod 43 to clamp and fix the steel door 3, and the operation is simple. At the positions corresponding to the moving plate 42 on both sides of the rotating frame 2, limit frames 45 are fixedly connected. A limiting rod 46 is slidably connected to the inner wall of the limit frame 45. One end of the limiting rod 46 close to the clamping plate 44 is fixedly connected to the moving plate 42. The limiting rod 46 restricts the rotation direction of the moving plate 42 and also enhances the stability between the moving plate 42 and the rotating frame 2. The other end of the screw 41 is fixedly connected to an auxiliary rod 47. Anti-slip rings are evenly provided on the arc surface of the auxiliary rod 47 to increase the friction between the hand and the screw 41 and facilitate the operation of the screw 41. On one side where the two clamping plates 44 are close to each other, a number of pressing plates 49 are fixedly connected. The number of pressing plates 49 is an elastic rubber plate, which increases the friction between the moving plate 42 and the steel door 3 and prevents the steel door 3 from shifting.

[0030] Refer to Figure 4 As shown in the figure, in this implementation: The auxiliary device 5 includes two fixing blocks 51. The fixing plate 1 is fixedly connected to the fixing blocks 51. A rotating column 52 threadedly penetrates through the inner wall of the fixing block 51. One end of the rotating column 52 close to the rotating shaft 6 is rotatably connected to a pressing plate 53. By providing the auxiliary device 5, it is realized that the operator only needs to rotate the column 52 to clamp and fix the rotating shaft 6, and the operation is convenient. A number of pressing blocks 56 are fixedly connected to the arc surface of the pressing plate 53. The pressing blocks 56 are elastic blocks, which increase the friction between the pressing plate 53 and the rotating shaft 6 and improve the stability. A sliding plate 54 is fixedly connected to the bottom surface of the pressing plate 53. A sliding groove 55 is provided on the upper surface of the fixing plate 1 at the position corresponding to the sliding plate 54. The inner wall of the sliding groove 55 is slidably connected to the surface of the sliding plate 54. The sliding plate 54 and the sliding groove 55 restrict the rotation direction of the pressing plate 53 and prevent the pressing plate 53 from rotating and shifting.

[0031] The working principle of a limit bracket for steel door spraying provided by the present utility model is as follows. In the present utility model, when spraying the steel door 3, first place the steel door 3 on the rotating frame 2, and then rotate the screw rods 41 at both ends. Due to the limitation of the rotation direction of the moving plate 42 by the limit rod 46, the screw rod 41 can only drive the moving plate 42 to translate. When the moving plates 42 at both ends are in pressing contact with the steel door 3, then rotate the rotating rod 43, and the rotating rod 43 drives the two clamping plates 44 to move towards each other. When the two clamping plates 44 are in pressing contact with the steel door 3, stop rotating, and then spray the steel door.

[0032] In the present utility model, when spraying the other side of the steel door 3, first rotate the two rotating columns 52 to move the two pressing plates 53 away from each other to release the fixation of the rotating shaft 6, then rotate the rotating frame 2, and then rotate the rotating columns 52. Under the action of the sliding plate 54 and the sliding groove 55, the rotation direction of the pressing plate 53 is limited so that it can only translate until the pressing plate 53 is in pressing contact with the rotating shaft 6 to fix the rotating shaft 6, and then spray the steel door.

[0033] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.
