Description

Technical Field

[0001] The utility model belongs to the technical field of shadowless lamps, and in particular relates to an anti-scratch shadowless lamp. Background Art

[0002] Shadowless lamps are commonly used lamps in operating rooms and are now popular. Technical personnel in related fields have found that the light-transmitting plates of current shadowless lamps are mostly fixed directly to the lampshade with screws. The advantage of using screws for fixing is that the appearance requirements of the lampshade and the light-transmitting plate are low, and only the accurate fixing position of the screws needs to be ensured. However, the problem with this method is that the edge of the light-transmitting plate is exposed, and there is a possibility of scratching hands when maintaining and cleaning it. This has already happened in actual use, and scratching hands may lead to secondary contamination. Utility Model Content

[0003] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a scratch-proof shadowless lamp.

[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0005] An anti-scratch shadowless lamp, comprising a cover body on which the shadowless lamp is installed, the cover body being integrally connected with an edge ring, the edge ring being symmetrically provided with two through grooves, the edge ring being provided with a threaded hole connected to the through grooves on the side, the threaded hole being threadedly connected with a positioning pin, a retaining ring being installed at the lower side of the edge ring, the retaining ring being provided with a plug post whose position specification and size match the through grooves, the plug post being provided with a blind hole whose specification and size match the positioning pin;

[0006] The side ring is provided with an upper mounting groove, the retaining ring is provided with a lower mounting groove, the specifications and sizes of the upper mounting groove and the lower mounting groove correspond to each other, the upper mounting groove and the lower mounting groove are both provided with a sealing groove, a sealing ring is installed in the sealing groove, the upper mounting groove and the lower mounting groove are installed with a side pressure ring, the cross section of the side pressure ring is U-shaped, and a light-transmitting plate is installed in the side pressure ring;

[0007] The edge ring, the retaining ring and the light-transmitting plate are all provided with rounded corners.

[0008] It is further defined that the end of the positioning pin is connected with a screw block, and such a design facilitates the rotation of the positioning pin.

[0009] It is further defined that the entrance end of the blind hole is provided with a chamfer, and such a design facilitates the guiding of the positioning pin.

[0010] It is further defined that the opening end of the side pressure ring is provided with an outwardly expanding bevel, and such a design facilitates the edge wrapping of the light-transmitting plate.

[0011] It is further defined that the sealing groove is arranged adjacent to the inner diameter edges of the side ring and the retaining ring. With such a design, the sealing ring installed in the sealing groove can prevent dust from entering the area of ​​the lower installation groove to the greatest extent.

[0012] The beneficial effects of adopting the utility model are:

[0013] With the structural design of the utility model, the light-transmitting plate can be installed without any auxiliary tools, which is more convenient and quicker than the installation by using a screwdriver or the like in the prior art;

[0014] By adopting the structural design of the utility model, the edge of the light-transmitting plate is completely covered, so there is no possibility of scratching hands during cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
