Detailed Description
The present invention will be described in further detail with reference to examples, but the present invention is not limited thereto.
Example 1
As shown in fig. 1 and 2, the tool for protecting the head of the countersunk head screw 1 by spraying is mounted on a head 11 of the countersunk head screw 1 when the countersunk head screw 1 is sprayed, and a screw groove 12 is formed on the head 11. Including rubber spare 2, rubber spare 2 includes disc 21 and sets up the boss 22 in disc 21 one side, disc 21 and boss 22 coaxial setting just the diameter of disc 21 is greater than the diameter of boss 22, boss 22 and nail groove 12 phase-match and can imbed in the nail groove 12, the diameter of disc 21 equals the diameter of the pin fin 11 of required protection, disc 21 can cover on the pin fin 11, makes disc 21 covers completely on the pin fin 11.
Before spraying, the boss 22 of the rubber part 2 is only required to be pressed into the nail groove 12 of the nail head 11 of the countersunk head screw 1 to be protected, and the disc 21 covers the upper surface of the nail head 11, so that the protection of the nail head 11 of the countersunk head screw 1 can be completed. After the spraying is finished, the rubber part 2 is taken out, and the rubber part is easy to disassemble and assemble and can be used repeatedly.
Preferably, a handle 23 is provided on the side of the disc 21 remote from the boss 22. Preferably, the handle 23 is a cylinder coaxial with the disc 21 and the boss 22, so as to facilitate the removal of the rubber member 2 after the spraying is completed.
Preferably, the handle 23, the disc 21 and the boss 22 are integrally formed.
The countersunk head screw 1 is exemplified by a gear groove countersunk head screw 1, and the side wall of the nail groove 12 is in a gear shape, so that the boss 22 is in a gear shape consistent with the nail groove 12, and the boss 22 is in clearance fit with the nail groove 12, so that the boss 22 can be embedded into the nail groove 12 to play a role in positioning.
Preferably, the boss 22 is a conical boss, and the size of the end of the boss 22 away from the disk 21 is smaller than the size of the end of the boss 22 connected with the disk 21. The size of one end of the lug boss 22, which is connected with the disc 21, is consistent with that of the nail groove 12, so that the lug boss 22 can be quickly embedded into the nail groove 12, and a quick and accurate positioning effect is achieved.
Example 2
The embodiment is improved on the basis of embodiment 1, and the improvement is as follows: but protection frock still includes that coaxial cover establishes the paster layer 3 on boss 22, paster layer 3 sets up the homonymy at disc 21 with boss 22, paster layer 3 is connected just with disc 21 the diameter on paster layer 3 is greater than the diameter of disc 21. The patch layer 3 includes a plurality of patches 4 having different diameters. The patches 4 on the patch layer 3 are detachably connected with the rubber part 2. The middle of the patch layer 3 is provided with a through hole with the same shape as the boss 22, and the through hole is used for sleeving the patch layer 3 on the boss 22 and can move along the boss 22, namely, the center of each patch 4 of the patch layer 3 is provided with a through hole for sleeving on the boss 22.
The protection tool can select the patch 4 with the same diameter as the nail head 11 according to the diameter of the nail head 11 of the countersunk head screw 1 to be protected, the patch 4 is coaxially sleeved on the boss 22, the technical effect of spraying protection on the countersunk head screws 1 with the nail heads 11 with different diameters is achieved, and the applicability is better.
The two sides of the patches 4 are provided with non-setting adhesives, so that the patches 4 are bonded together, and the protective tool can be taken out and reused after spraying is finished.
Other parts in this embodiment are substantially the same as those in embodiment 1, and thus are not described in detail.
Example 3
The embodiment is improved on the basis of the embodiment 2, and the improvement is as follows: the diameter of the patches 4 close to the disc 21 decreases in order to the diameter of the patches 4 further from the disc 21, the diameter of the patch 4 furthest from the disc 21 being equal to the diameter of the head 11 to be protected. The multilayer patches 4 form an inverted pagoda-shaped structure with the diameters decreasing from top to bottom, so that the sprayed coating is not easy to adhere to the protection tool, the protection tool is easy to maintain after spraying is finished, and the integrity of the coating near the nail head 11 of the countersunk head screw 1 can be protected to the maximum extent.
Preferably, the thickness of the patch layer 3 is matched with the thickness of a coating to be sprayed, the thickness of the patch layer 3 is not less than the thickness of the coating to be sprayed, and the number of layers of the patch layer 3 is matched with the number of layers of the sprayed coating, so that the completeness of the coating after the tool is assembled and disassembled can be protected to the maximum extent. Preferably, the diameters of two adjacent patches 4 differ by 0.1 mm.
The diameters of two adjacent patches 4 are not easy to be too large in difference, and the thicknesses of the patches 4 are not easy to be too thick, so that the coating is not stained on the upper surface of the nail head 11 in the spraying process, and the condition that the nail head 11 is sprayed with the coating due to untight protection is avoided.
The countersunk head screw 1 required to be protected is taken as a gear groove countersunk head screw 1 with the head 11 diameter of 9mm, and the thickness of the coating layer to be sprayed on the cover arranged on the machine body is 0.4-0.5 mm. As shown in fig. 3, the patch layer 3 includes three patches 4, namely a first patch 41, a second patch 42 and a third patch 43, which are sequentially arranged from top to bottom, and the thicknesses of the patches are all 0.2mm, and the diameters of the first patch 41, the second patch 42 and the third patch 43 are sequentially reduced to form an inverted pagoda shape; the diameters of the first patch 41 and the nail head 11 of the countersunk head screw 1 are consistent and are 9mm, and the diameters of the first patch 41, the second patch 42 and the third patch 43 are gradually increased by 0.1 mm. The rubber part 2 and the patch layer 3 are connected into a whole through the adhesive sticker.
As shown in fig. 4 and 5, before spraying, the boss 22 of the protection tool is embedded into the nail groove 12 of the nail head 11, and the third patch 43 is pressed above the nail head 11, because the patch layer 3 is coaxially arranged with the nail head 11, and the diameter of the first patch 41 is the same as that of the nail head 11, the first patch 41 completely covers the nail head 11, that is, the accurate protection of the nail head 11 of the gear groove countersunk head screw 1 is completed, so that the nail head 11 of the gear groove countersunk head screw 1 cannot be coated during the spraying of the cover cap installed on the machine body. After the spraying is finished, the protection tool is taken down, the dismounting is simple and easy, and the protection tool can be recycled.
Other parts in this embodiment are substantially the same as those in embodiment 1 or 2, and therefore are not described in detail.
The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the technical matters of the present invention all fall into the protection scope of the present invention to any simple modification and equivalent change of the above embodiments.
