Description

Technical Field

[0001] The utility model relates to the technical field of camera films, in particular to a film for a single-lens reflex camera lens. Background Art

[0002] SLR cameras are a type of camera, and digital SLR cameras are single-lens reflex digital cameras. The light entering the lens is reflected upward by the reflector onto a piece of frosted glass. Early SLR cameras had to be held at waist level and looked down at the frosted glass to frame the shot. Although the image on the frosted glass was upright, it was inverted left and right. In order to correct this defect, the current eye-level SLR cameras have a pentaprism installed above the frosted glass. This prism reflects the light multiple times to change the optical path and transmits the image to the eyepiece. At this time, the image is upright up and down and corrected left and right.

[0003] The unique design of the reflector and prism allows the photographer to directly observe the image through the lens through the viewfinder. The lens on the SLR camera needs to be covered with a film for protection. The film for the SLR camera lens needs to be torn off from the base layer and pasted on the SLR camera lens.

[0004] After searching, it is found that most of the films for SLR camera lenses can only provide scratch protection for the lens. Once the user's fingers touch the film for SLR camera lenses, fingerprints and oil stains are likely to remain on the film paper and are inconvenient to wipe off. In addition, most of the films for SLR camera lenses are printed on base paper. When using them, the film needs to be torn off from the base paper. However, directly tearing off the film is likely to cause the film to be torn, which affects the efficiency of the film and increases the cost of the film.

[0005] There is an urgent need for a film for SLR camera lenses to solve the technical defects proposed in the above-mentioned technology. Utility Model Content

[0006] The utility model aims to provide a film for a single-lens reflex camera lens, so as to solve the problem in the above-mentioned background technology that it is inconvenient to completely tear off the film for use.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a film for a SLR camera lens, comprising a base paper, a lens film bonded to the front end of the base paper, a release paper installed at the front end of the lens film, a first auxiliary line and a second auxiliary line respectively arranged at the front end of the release paper, an auxiliary reserved opening arranged at the top of the lens film, an outer diameter adhesive layer installed at the outer diameter of the lens film, an inner diameter adhesive layer installed on the inner side of the lens film, and an explosion-proof film layer fixedly bonded to one end of the lens film.

[0008] Preferably, the first auxiliary line and the second auxiliary line are cutting dotted lines, and the first auxiliary line and the second auxiliary line are arranged at the front end of the release paper.

[0009] Preferably, the first auxiliary line is perpendicular to the lens film, and the second auxiliary line is parallel to the lens film.

[0010] Preferably, a strong scratch-resistant coating is fixedly bonded to one end of the inner diameter bonding layer, and a nano coating is fixedly connected to one end of the strong scratch-resistant coating.

[0012] Preferably, the lens film is bonded to a base paper, and a circular reserved groove is provided on the base paper.

[0014] By providing a base paper, a lens film, a first auxiliary line, a peeling paper, a second auxiliary line and an auxiliary reserved opening, the lens film can be pasted on the lens of a SLR camera to protect the lens. Before using the lens film, the base paper needs to be torn off first. When tearing, the peeling paper can be torn off from the base paper using the first auxiliary line and the second auxiliary line. When peeling, first hold the edge of the first auxiliary line to tear off a part of the peeling paper outside the lens film, then hold the second auxiliary line to tear off another part of the peeling paper, and then tear off the lens film from the base paper through the auxiliary reserved opening for use. This structure realizes the function of being easy to tear off completely for use.

[0015] By providing an outer diameter adhesive layer and an inner diameter adhesive layer, the inner diameter adhesive layer on the inner side of the lens film can be bonded to the outer wall of the lens, and then the outer diameter adhesive layer on the lens film is bonded to the lens of the SLR camera. The lens film improves the overall bonding stability through the two sets of bonding structures of the outer diameter adhesive layer and the inner diameter adhesive layer, and the structure realizes the function of facilitating firm bonding;

[0016] By arranging nano-coating, high-definition film layer, electrostatic adsorption layer, explosion-proof film layer and strong scratch-resistant coating, the nano-coating installed on the lens film is arranged on the outermost side, and the user's fingers will not leave fingerprints on it when they touch the nano-coating, thus avoiding the contact affecting the use effect of the lens. The electrostatic adsorption layer and explosion-proof film layer have the functions of electrostatic protection and explosion-proof protection. The strong scratch-resistant coating on the lens film can improve the overall durability. This structure realizes the functions of anti-scratch and anti-fingerprint.
