[0020] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0021] like Figure 1-4 As shown, a production equipment for a paint production line includes a fastening assembly, the fastening assembly includes a first connecting plate 1, a second connecting plate 2, a bolt 3 and a protection mechanism, the first connecting plate 1 and the second connecting plate 2 are connected by the bolt 3, the protection mechanism is arranged on the first connecting plate 1, the bolt 3 is connected to the first connecting plate 1 through the protection mechanism, the protection mechanism includes a protection assembly and a positioning assembly, the protection assembly is arranged on the first connecting plate 1, the positioning assembly is arranged on the protection assembly, and the positioning assembly is connected to the protection assembly;

[0022] The protection assembly includes a cap 4 and a protection unit. The first connecting plate 1 is provided with an annular limiting groove. The cap 4 is arranged on the first connecting plate 1. The bottom end of the cap 4 extends into the limiting groove. The cap 4 is slidably connected to the limiting groove.

[0023] The protection unit is arranged in the limiting groove, and the protection unit includes a first limiting ring 5, a second limiting ring 6, a supporting ring 7, a first spring 8, a sliding ring 9 and a ball screw 10. The first limiting ring 5 and the second limiting ring 6 are both arranged in the limiting groove, the inner ring of the first limiting ring 5 is connected to the inner wall of the limiting groove, the outer ring of the first limiting ring 5 is abutted against the inner wall of the cap 4, the inner ring of the second limiting ring 6 is abutted against the outer ring of the cap 4, the outer ring of the second limiting ring 6 is connected to the inner wall of the limiting groove, the cap 4 is slidably connected to the first limiting ring 5 and the second limiting ring 6, the sliding ring 9 is arranged in the limiting groove, the sliding ring 9 is slidably connected to the limiting groove, and the supporting ring 7 is arranged on the sliding groove. On the ring 9, the abutting ring 7 is coaxially arranged with the sliding ring 9, and the end of the abutting ring 7 away from the sliding ring 9 abuts against the bottom end of the cap 4, and the abutting ring 7 is located between the first limiting ring 5 and the second limiting ring 6. The abutting ring 7 is slidingly connected with the first limiting ring 5 and the second limiting ring 6, and the ball screw 10 is arranged on the inner wall of the limiting groove. The cap 4 is provided with an annular groove, and the ball screw 10 is located in the groove. The ball screw 10 is slidingly connected to the groove. There are several first springs 8, and each first spring 8 is evenly arranged along the outer circumference of the sliding ring 9. One end of the first spring 8 is connected to the sliding ring 9, and the other end of the first spring 8 is connected to the bottom end inside the limiting groove;

[0024] There are two positioning assemblies, both of which are arranged on the outer ring of the cap 4. The two positioning assemblies are symmetrically arranged about the axis of the cap 4. The bolt 3 is connected to the cap 4 through the positioning assemblies.

[0025] Here, when the bolt 3 is needed for protection, the cap 4 is first moved so that the bottom end of the cap 4 moves toward the direction of the first connecting plate 1. At this time, the cap 4 moves into the limiting groove. At this time, the cap 4 is slidingly connected with the first limiting ring 5 and the second limiting ring 6. At the same time, the ball screw 10 is located in the card slot on the cap 4. The cap 4 is limited by the ball screw 10 to prevent the cap 4 from moving up and down, and the cap 4 can rotate freely in the limiting groove. Here, the restoring force of the first spring 8 is less than the limiting force of the ball screw 10.

[0026] Here, when the cap 4 is separated from the first connecting plate 1, the sliding ring 9 can be moved by the restoring force of the first spring 8, and the sliding ring 9 drives the abutment ring 7 to move, so that the abutment ring 7 is located between the first limiting ring 5 and the second limiting ring 6. The limiting groove is sealed by the abutment ring 7 to prevent dust from falling into the limiting groove, thereby facilitating the installation and disassembly of the cap 4 and improving practicality.

[0027] like Figure 5As shown, as a preference, in order to limit the bolt 3, prevent the bolt 3 from rotating, and improve the positioning effect, the positioning assembly includes a positioning block 11, a positioning rod 12, a screw rod 13, a second spring 14 and a threaded block 15, the positioning block 11 is arranged in the cap 4, the threaded block 15 is arranged on the outer ring of the cap 4, the positioning rod 12 is arranged on the side of the threaded block 15 away from the cap 4, the screw rod 13 is arranged between the positioning rod 12 and the positioning block 11, one end of the screw rod 13 is connected to the positioning block 11, and the screw rod 13 is arranged on the outer ring of the cap 4. The other end passes through the threaded block 15 and is connected to the positioning rod 12. The screw rod 13 is coaxially arranged with the positioning rod 12. The screw rod 13 is threadedly connected to the threaded block 15. The positioning rod 12 is slidingly connected to the threaded block 15. The second spring 14 is arranged between the positioning block 11 and the inner wall of the cap 4. The second spring 14 is sleeved on the screw rod 13. One end of the second spring 14 is connected to the positioning block 11. The other end of the second spring 14 abuts against the inner wall of the cap 4. The end of the positioning block 11 away from the screw rod 13 abuts against the bolt 3.

[0028] Preferably, in order to facilitate the rotation of the positioning rod 12 and reduce labor intensity, a sleeve 16 is provided at one end of the positioning rod 12 away from the screw rod 13, and the sleeve 16 is sleeved on the positioning rod 12. The sleeve 16 is slidingly connected to the positioning rod 12, and an elastic rope 17 is provided between the sleeve 16 and the threaded block 15. One end of the elastic rope 17 is connected to the sleeve 16, and the other end of the elastic rope 17 is connected to the threaded block 15.

[0029] When the bolt 3 needs to be protected, the positioning rod 12 is first pulled, and the positioning rod 12 drives the screw rod 13 to move, and the screw rod 13 drives the positioning block 11 to move, so that a certain distance is left between the positioning block 11 and the bolt 3. At this time, the positioning rod 12 is rotated, and the positioning rod 12 drives the screw rod 13 to rotate, and the screw rod 13 drives the positioning block 11 to rotate, so that the screw rod 13 is located in the threaded block 15, and the threaded block 15 is used to position the screw rod 13, thereby facilitating the installation of the cap 4. At this time, the second spring 14 is in a compressed state, and the cap 4 can be moved so that the cap 4 is located in the limit groove. Here, when the cap 4 moves to the preset position, the positioning rod 12 can be rotated again, and the positioning rod 12 drives the screw rod 13 to rotate, so that the screw rod 13 is separated from the threaded block 15. At this time, the positioning block 11 can be moved by the restoring force of the second spring 14, so that the positioning block 11 is abutted against the bolt 3, and the bolt 3 is positioned by the positioning block 11, preventing the bolt 3 from rotating and improving the positioning effect.

[0030] Here, when the bolt 3 needs to be removed, it is only necessary to pull the sleeve 16 so that the end of the sleeve 16 close to the threaded block 15 moves to the end of the positioning rod 12 away from the screw rod 13, thereby increasing the force arm of the positioning rod 12. At this time, the elastic rope 17 is in a stretched state. At this time, the sleeve 16 is rotated, and the sleeve 16 drives the positioning rod 12 to rotate. The positioning rod 12 drives the cap 4 to rotate. At the same time, the positioning rod 12 drives the screw rod 13 and the positioning plate to rotate, and the bolt 3 is rotated through the positioning plate, thereby loosening the bolt 3, so that the operator can remove the bolt 3 without carrying any auxiliary tools, thereby improving convenience.

[0031] like Figure 6 As shown, as a preference, in order to achieve the abutment of the bolt 3, reduce the gap between the bolt 3 and the first connecting plate 1, and improve the positioning effect, a abutment component is provided on the inner wall of the top end of the cap 4, and the abutment component includes a connecting rod 18, a push plate 19 and an abutment unit. The push plate 19 is horizontally arranged in the cap 4, and the push plate 19 is slidably connected to the cap 4. The connecting rod 18 is vertically arranged on the inner wall of the top end of the cap 4. There are several abutment units, and each abutment unit is evenly arranged along the outer circumference of the connecting rod 18. The abutment unit includes a support rod 20, a slider 21 and a third spring 22, a strip-shaped moving groove is provided on the push plate 19, the slider 21 is arranged in the moving groove, the support rod 20 is arranged between the connecting rod 18 and the slider 21, one end of the support rod 20 is hinged to the slider 21, and the other end of the support rod 20 is hinged to the outer ring of the connecting rod 18, the third spring 22 is arranged in the moving groove, one end of the third spring 22 is connected to the slider 21, and the other end of the third spring 22 is connected to the inner wall of the moving groove close to the connecting rod 18, and the end of the push plate 19 away from the connecting rod 18 is in contact with the end face of the bolt 3.

[0032] Here, when the cap 4 is located in the limiting groove, the top end of the bolt 3 will abut against the push plate 19, the push plate 19 drives the slider 21 to move, and the slider 21 drives the support rod 20 to move. At this time, the third spring 22 is in a stretched state, and the elastic abutment of the bolt 3 is achieved through the restoring force of the third spring 22, thereby reducing the gap between the bolt 3 and the first connecting plate 1 and improving the positioning effect. Here, multiple abutment units are used to make the bolt 3 subjected to multi-directional force, thereby improving the positioning effect.

[0033] Compared with the prior art, the production equipment for the paint production line protects the bolt 3 through the cap 4 to prevent external dust from adhering to the bolt 3, and limits the cap 4 through the protection unit. At the same time, when the cap 4 is separated from the limiting groove, the restoring force of the first spring 8 can also seal the limiting groove to prevent dust from falling into the limiting groove and affecting the installation and disassembly of the cap 4, thereby improving practicality. Here, the bolt 3 is positioned by the positioning assembly to prevent the bolt 3 from rotating. At the same time, the force arm of the positioning rod 12 is increased by the sleeve 16 to facilitate the rotation of the bolt 3, so that the operator can disassemble the bolt 3 without carrying any auxiliary tools, thereby improving convenience. Here, the top end of the bolt 3 is limited by the abutment assembly, the gap between the bolt 3 and the first connecting plate 1 is reduced, and the positioning effect is improved.
