Powder spraying gun with protective structure for plastic spraying processing

Abstract

The powder spraying gun with the protective structure for the plastic spraying processing comprises a grip, a powder spraying gun barrel body, a nozzle and a control grip, one end of the grip is fixedly installed on the left side of the bottom of the powder spraying gun barrel body, and the nozzle is installed at the right end of the powder spraying gun barrel body. Through the arrangement of the protection structure, when a user applies pressure to the control grip, the tooth block is driven to rotate, the tooth block drives the rotating rod to rotate, and when the rotating rod drives the limiting mechanism to rotate, the buckle rotates along with the control grip due to the fact that the clockwise arrangement direction of the buckle protruding points is the same as the moving track of the control grip; however, when the control grip is reset along with the reset structure, the movement tracks of the buckle and the clamping groove are different, and the buckle limits the rotation of the tooth block, so that the fingers of the worker can be liberated in the plastic spraying process, and the phenomenon that the hand of the worker is hard due to non-circulation of blood under long-time work is avoided.

[0024] Example 1

[0025] like Figure 1-7As shown, the utility model is a powder spray gun with a protective structure for spraying plastics, comprising a grip 1, a powder spray gun barrel 2, a nozzle 3 and a control grip 4, one end of the grip 1 is fixedly installed with the left side of the bottom of the powder spray gun barrel 2, the nozzle 3 is installed at the right end of the powder spray gun barrel 2, the control grip 4 is installed on the right side of the bottom of the powder spray gun barrel 2, a protective structure 5 is arranged inside the control grip 4, and a limiting mechanism 6 is arranged at one end of the protective structure 5, which solves the problem of blood circulation and stiffness of the hands of workers after long-term work. The protective structure 5 includes an arc block 51, a tooth groove provided in the arc block 51, a tooth block 52, two rotating rods 53 and two tension springs 54. One end of the arc block 51 is fixedly connected to the side of the handle 1, and the other end of the arc block 51 passes through the outside of the control handle 4. The tooth block 52 is located inside the control handle 4, and the bottom end of the tooth block 52 is meshed with the inside of the tooth groove. One end of the two rotating rods 53 is fixedly connected to the two sides of the tooth block 52, and the two tension springs 54 are sleeved with the two rotating rods 53. , one end of the tension spring 54 is fixedly connected to the side of the tooth block 52, and the other end of the tension spring 54 is fixedly connected to the inner wall of the control handle 4. A movement groove adapted to the tension spring 54 is opened inside the control handle 4, and the end of the rotating rod 53 away from the tooth block 52 passes through the outside of the control handle 4. The limiting mechanism 6 includes a button 63, a moving rod 61, a spring 64 and a buckle 62. The button 63 is located on both sides of the handle 1, one end of the moving rod 61 passes through the inside of the rotating rod 53 and is fixedly connected to the buckle 62, and the moving rod 6 The other end of 1 is fixedly connected to the inner wall of the button 63, the spring 64 is sleeved on the surface of the moving rod 61, one end of the spring 64 is fixedly connected to the inner wall of the button 63, and the other end of the spring 64 is fixedly connected to the side of the rotating rod 53 to limit the moving trajectory of the protective structure 5. The surface of the buckle 62 is provided with a plurality of convex points, one end of the convex point is processed as an arc, and the plurality of arcs are clockwise, so it is more convenient for the buckle 62 to rotate clockwise, and when it rotates counterclockwise, the side of the buckle 62 is in a vertical state to limit the reset of the control handle 4.

[0026] Example 2

[0027] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 7 A card slot and a through slot are provided inside the rotating rod 53, and the card slot is connected to the through slot. The surface of the buckle 62 contacts the inner wall of the card slot. The diameter of the through slot is larger than the diameter of the card slot. When the buckle 62 is located inside the card slot, the control handle 4 cannot be reset. When the buckle 62 is located inside the through slot, the tension spring 54 will drive the tooth block 52 to reset. Grooves are provided on both sides of the top of the arc block 51. The width of the groove is larger than the width of the tooth groove, which can make the tooth block 52 disengage from the tooth groove. The center of the arc block 51 is at the same position as the center of the movement trajectory of the control handle 4. One end of the arc block 51 that passes through the outside of the control handle 4 is fixedly connected to the limit block 7, and the limit block 7 limits the outward rotation angle of the control handle 4.

[0028] During use of the present invention, when the user applies pressure to the control handle 4, the tooth block 52 is driven to rotate, and the tooth block 52 drives the rotating rod 53 to rotate. When the rotating rod 53 drives the limiting mechanism 6 to rotate, because the clockwise opening direction of the convex point of the buckle 62 is the same as the moving trajectory of the control handle 4, the buckle 62 rotates together. However, when the control handle 4 is reset with the reset structure, the movement trajectory of the buckle 62 and the card slot is different. The buckle 62 limits the rotation of the tooth block 52. When the control handle 4 needs to be reset, the user presses the button 63, and the button 6 3 drives the moving rod 61 to move, and the movement of the moving rod 61 drives the buckle 62 to move while squeezing the spring 64. After the buckle 62 is inserted into the through groove from the slot, the moving rod 61 pushes the rotating rod 53 to move, and the rotating rod 53 moves to drive the tooth block 52. When the tooth block 52 is separated from the tooth groove to the groove, the control handle 4 is driven to reset by the reset structure. After the control handle 4 is reset, the user releases the button 63, the tension spring 54 and the spring 64 are reset, and the protective structure 5 and the limiting mechanism 6 are reset for the next use, and the operation is completed.

[0029] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
