[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details.

[0024] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0025] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0026] In order to solve the problem that the metal spray paint protective device is easily unstable when it is used by plug-in fixing, which reduces the tightness of the connection between the metal part and the protective device and reduces the quality of the paint spraying on the metal part, please refer to Figures 1 to 5 The structure of the device body is a metal part body 1 and a flange ring 2. A baffle plate 3 is overlapped on the side of the flange ring 2. The baffle plate 3 is in close contact with the flange ring 2 to prevent the paint from flowing into the side of the flange ring 2 when the metal part body 1 is sprayed with paint, thereby reducing the quality of spraying paint on the metal part body 1. A hollow plug-in plate 12 is plugged into the side of the metal part body 1 through an opened groove. The hollow plug-in plate 12 is provided to provide a preliminary blocking and shielding effect for the metal part body 1. The side of the hollow plug-in plate 12 is fixedly connected to the baffle plate 3 to fix the position of the hollow plug-in plate 12. A sealed bearing 4 is fixedly connected to the side of the baffle plate 3 through an opened groove, and the inner ring side of the sealed bearing 4 does not contact the baffle plate 3, thereby preventing the baffle plate 3 from contacting the inner ring of the sealed bearing 4, causing rotation resistance to the inner ring of the sealed bearing 4, and improving the functional structural stability of the device.

[0027] The inner ring of the sealed bearing 4 is fixedly connected to the rotating rod 6. The sealed bearing 4 is set to fix the rotating position of the rotating rod 6, and at the same time it is convenient to realize the relative rotation of the rotating rod 6 and the baffle plate 3. The end face of the rotating rod 6 is connected to the transmission rod 7 through the meshing rotation of the bevel gear, which is convenient for driving the transmission rod 7 to rotate by rotating the rotating rod 6. Both ends of the side of the transmission rod 7 are fixedly connected to the inner ring of the limit bearing 8. The two limit bearings 8 provide rotational support for the transmission rod 7 to prevent the transmission rod 7 from shaking during rotation, reduce the meshing effect of the bevel gear, and improve the structural stability of the device parts. The outer ring of the limit bearing 8 is fixedly connected to the hollow plug-in plate 12 to fix the position of the limit bearing 8. The two end faces of the transmission rod 7 are fixedly connected with threaded blocks 9.

[0028] The threaded block 9 is threadedly connected with a hollow threaded plate 10. The threaded blocks 9 fixedly connected at both ends of the transmission rod 7 have reverse threads, and the two hollow threaded plates 10 have unidirectional threads, so that when the transmission rod 7 is rotated, the two hollow threaded plates 10 can move in opposite directions. The end faces of the hollow threaded plates 10 are fixedly connected with rubber plates 11. The arranged rubber plates 11 provide an anti-slip effect. A hollow plug-in plate 12 extends from one end of the rubber plate 11 away from the hollow threaded plate 10. The end face of the rubber plate 11 overlaps the metal part body 1. By centrifugally moving the two rubber plates 11, the rubber plates 11 are in close contact with the inner cavity of the metal part body 1, so that the position of the hollow plug-in plate 12 is fixed, and the shielding plate 3 is prevented from being in loose contact with the flange ring 2 during transmission, thereby reducing the protective effect of the protective device on the metal parts and reducing the paint quality of the metal parts.

[0029] The inner ring surface of the flange ring 2 is fixedly connected to the metal body 1, so that the flange ring 2 and the metal body 1 are connected as a whole. The inner ring side of the sealing bearing 4 is fixedly connected to a rotating block 5, and the side of the rotating block 5 is fixedly connected to the rotating rod 6. The rotating block 5 is arranged to facilitate the rotation of the rotating rod 6 from the outside, thereby improving the convenience of using the device. The outer ring surface of the flange ring 2 is sleeved with a shielding ring 13, and the shielding ring 13 provides further shielding for the flange ring 2 to prevent the paint from penetrating. The side of the shielding ring 13 is fixedly connected to the shielding plate 3 to fix the position of the shielding ring 13. The side of the flange ring 2 is provided with a plug-in block 14 by opening four equidistantly arranged through grooves, and the plug-in block 14 is provided on the side of the flange ring 2. The through groove provides a shielding and blocking effect to prevent the paint liquid from flowing in and reduce the quality of painting metal parts. The side of the baffle plate 3 is connected with a connecting rod 15 by opening four equidistantly arranged through grooves, and the four plug-in blocks 14 are fixedly connected to the four connecting rods 15 in a one-to-one correspondence. The end face of the plug-in block 14 is fixedly connected to the connecting rod 15, and the end of the connecting rod 15 away from the plug-in block 14 is overlapped with a fastening plate 17, and the connecting rod 15 and the fastening plate 17 are threadedly connected with a bolt 16. By threading a bolt 16 with a fastening plate 17 and the connecting rod 15, the functional structural stability of the device is improved, the position of the plug-in block 14 is fixed during the transmission process, and it is convenient to replace the damaged plug-in block 14, thereby improving the convenience of using the device.

[0030] The working principle, size and model are irrelevant to the function of this application, so they are not described in detail. The control method of the utility model is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0031] How it works

[0032] When using the protective device for metal spray painting, the user makes the baffle plate 3 fit with the flange ring 2, thereby extending the hollow plug-in plate 12 into the groove of the metal component body 1. To prevent the baffle plate 3 from being loosely in contact with the flange ring 2, the rotating block 5 is rotated, and the rotating rod 6 drives the transmission rod 7 to rotate through the meshing action of the bevel gears. The threaded blocks 9 fixedly connected at both ends of the transmission rod 7 have reverse threads and are threadedly connected to two hollow threaded plates 10 with the same direction of threads, and the side surfaces of the hollow threaded plates 10 are slidably connected to the hollow plug-in plate 12, so that the hollow threaded plate 10 is prevented from rotating when moving along the threaded path of the threaded block 9, thereby improving the functional structural stability of the device, and realizing the centrifugal movement of the two rubber plates 11 during the transmission process, so that the two rubber plates 11 are in close contact with the metal component body 1.

[0033] During the transmission process, the baffle plate 3 and the flange ring 2 are fixed to each other, and the paint liquid is prevented from penetrating into the side of the flange ring 2, thereby improving the protective effect of the protective device and the quality of painting of metal parts. The plug-in block 14 is extended into the through groove of the flange ring 2 to prevent the paint liquid from flowing into the through groove of the flange ring 2 and reducing the protective effect of the protective device. At the same time, the plug-in block 14 is prevented from being damaged due to long-term use. By rotating the bolt 16, the contact bolt 16 fixes the position of the connecting rod 15 and the fastening plate 17, so that the plug-in block 14 can be easily disassembled and the convenience of the device can be improved. During the transmission process, the bolt 16 improves the stability of the position fixation of the plug-in block 14, prevents the plug-in block 14 from shaking, reduces the shielding effect of the through groove of the flange ring 2, improves the functional structural stability of the device, thereby improving the protective effect of the protective device on metal parts and improving the quality of painting of metal parts.
