Detailed Description

In order to make those skilled in the art better understand the technical solution of the present application, the following further describes the technical solution of the present application with reference to the drawings and the embodiments.

Referring to the coating tool for the corner cube prism shown in fig. 1 to 8, the corner cube prism 10 is trimmed with an assembling clamping surface 10a, and one side of the assembling clamping surface 10a is provided with a plurality of prism surfaces 10b in different planes. The prism surface 10b of the pyramid prism 10 disclosed in the present application is provided with three prism surfaces connected in the circumferential direction, and the assembly clamping surface 10a is generally used as a clamping surface for assembling and clamping the pyramid prism 10 on an optical device after the prism surface 10b is coated with a film.

In order to solve the problems of the conventional pyramid prism 10 with a plurality of prism faces 10b during multiple coating, the present application designs a coating tool for solving the problems, as shown in fig. 5-7, the coating tool is clamped on the assembly clamping face 10a and suspends the prism face 10b to be coated. After the coating tool is used for clamping, the problem that the center and each prism surface 10b are in a completely exposed state at the same time due to the existing center clamping mode formed by a plurality of prism surfaces 10b can be solved, synchronous coating operation can be carried out on the three suspended prism surfaces 10b and the center after the center clamping interference is solved, the problems that coating thicknesses are overlapped, the center is exposed, coating is dropped and coating efficiency is not high due to the fact that multiple coatings are carried out at present are solved, and coating quality and using effect of the pyramid prism 10 are improved.

As shown in fig. 3 to 4, the assembly clamping surfaces 10a are symmetrically located on the pyramid prism 10, the coating tool includes a base 1, clamping blocks 11 symmetrically extending from one side of the base 1 and close to the assembly clamping surfaces 10a on each side, and clamping members contacting the assembly clamping surfaces 10a are disposed on the clamping blocks 11. When the device is used, the pyramid prism 10 is placed between the symmetrical clamping blocks 11, the assembly clamping surfaces 10a on the two sides correspond to the inner side walls of the clamping blocks 11, and then the clamping parts are driven to be tightly attached to the assembly clamping surfaces 10a on each side, so that the plurality of prism surfaces 10b and the tops of the pyramid prism 10 can be clamped in a hanging mode.

As shown in fig. 4, the clamping component is a set screw 2 (preferably a straight tightening structure) threaded through each side of the clamping block 11, and the contact end surfaces of the set screw 2 and the assembly clamping surface 10a are in a flat structure abutting against each other. The end face of the fastening screw 2 is flatly attached and pressed with the assembling clamping face 10a by rotating the fastening screw, and the clamping of the pyramid prism 10 can be quickly realized. During actual operation, the pyramid prism 10 is clamped by rotating the set screw 2 without falling, so that abrasion of an excessive clamping force on the assembling clamping surface 10a is avoided.

In order to avoid contact abrasion between the fastening screw 2 and the mounting and clamping surface 10a, as shown in fig. 4, an anti-abrasion tape 3 is detachably adhered to the end surface of the fastening screw 2 contacting the mounting and clamping surface 10a, which can effectively avoid hard damage of the fastening screw 2 to the mounting and clamping surface 10 a.

Because the fastening screw 2 needs to rotate to clamp the assembly clamping face 10a, in the process of clamping and rotationally clamping the fastening screw 2 and the assembly clamping face 10a, the fastening screw 2 drives the anti-abrasion tape 3 to cause certain rotational abrasion to the assembly clamping face 10a, and meanwhile, the anti-abrasion tape 3 also has the problems of rotational curling and falling to affect the clamping effect on the assembly clamping face 10a, so that as shown in fig. 8, the T-shaped nail 4 is rotatably penetrated through the end face of the fastening screw 2, and the anti-abrasion tape 3 is adhered to the surface of the T-shaped nail 4. When clamping tightly, order about 4 terminal surfaces of T type nail and the abrasionproof sticky tape 3 that bonds and assemble through rotatory holding screw 2 and press from both sides tight face 10a and hug closely the contact to when further screwing holding screw 2, because there is contact friction after T type nail 4 contacts with assembly holding surface 10a through abrasionproof sticky tape 3, and then restriction T type nail 4 is along with holding screw 2's continuous rotation, thereby can effectively avoid holding screw 2 to the rotatory wearing and tearing of assembly holding surface 10a, and abrasionproof sticky tape 3 has the rotatory drawback of curling or dropping.

The principle of this application is: when the device is used, the pyramid prism 10 is placed between the symmetrical clamping blocks 11, the assembling clamping surfaces 10a on two sides correspond to the inner side walls of the clamping blocks 11, then the T-shaped nail 4 and the anti-abrasion adhesive tape 3 on the end part of the T-shaped nail are flatly attached and pressed with the assembling clamping surfaces 10a by rotating the fastening screw 2, the clamping of the pyramid prism 10 can be quickly realized, the tip and each prism surface 10b are in a completely exposed state at the same time, after the clamping interference of the tip is solved, synchronous film coating operation can be carried out on three suspended prism surfaces 10b and the tip, the problems that the film coating thicknesses of multiple film coatings are overlapped, the tip is exposed, the film coatings fall off at present and the film coating efficiency is low are eliminated, and the film coating quality and the using effect of the pyramid prism 10 are improved. During actual operation, the pyramid prism 10 is clamped by rotating the set screw 2 without falling, so that abrasion of an excessive clamping force on the assembling clamping surface 10a is avoided.

The foregoing shows and describes the basic principles, essential features, and advantages of the application. Without departing from the spirit and scope of this application, there are also various changes and modifications that fall within the scope of the claimed application.
