Description

Technical Field

[0001] The utility model relates to the technical field of reflectors, in particular to a reflector provided with a film pre-fixing structure. Background Technique

[0002] A reflector is an optical device commonly used in fields such as photography, videography, and lighting. Its main function is to reflect light, thereby changing the direction and distribution of light to improve the light quality or create a specific light and shadow effect. The reflector can improve the reflection effect through a special film. The film is a material with high reflection performance and can effectively reflect light or other types of radiation, and has a wide range of applications.

[0003] In the prior art, a Chinese patent with the authorization announcement number of CN220269232U discloses a reflector for improving the positioning of arc surface film sticking, belonging to the field of reflectors. Its technical key points include a reflector. A reflection film is provided below the reflector, and the shape of the outer surface of the reflection film matches the shape of the inner wall of the reflector. A top annular frame is provided below the reflection film, and a bottom annular frame is provided below the top annular frame. Four end corners of the upper end surface of the bottom annular frame are fixedly provided with a connecting rod. Through the utility model reflector, the heat insulation film on its inner wall can be replaced without removing the internal bulb, thereby improving the safety and convenience of the device when replacing the heat insulation film.

[0004] Currently, most reflectors on the market still have certain deficiencies when in use. For example, as described in the above document, a top annular frame is provided below the reflection film, and a bottom annular frame is provided below the top annular frame. While this kind of frame improves the efficiency of replacing the film, it will have an impact on the light. The rod will affect the refraction of the light and reduce the light reflection effect. Secondly, the reflector generally needs to be fixed on a device. Most reflectors on the market are installed by threads, which is rather troublesome to use. Content of the Utility Model

[0028] Embodiment 1:

[0029] As Figures 1 - 4 shown in the technical solution, the present invention provides the following technical solutions: To solve the problem that the reflection cover does not have a film pre-fixing structure, which affects the efficiency during film installation and fixation, an extrusion mechanism is disclosed:

[0031] When fixing the film on the reflector, move one side of two films of appropriate size between the first pressing rod 103 and the second pressing rod 106, and then pressing the second pressing rod 106 can drive the guide block 105 to move. When the guide block 105 moves, it can slide through the guide groove 104. When the second pressing rod 106 slides to the side of the film, it can perform extrusion. At this time, the film can be extruded by the second pressing rod 106 and the first pressing rod 103. When the second pressing rod 106 is extruding, it can drive the half-threaded block 107 to move. When the half-threaded block 107 of the second pressing rod 106 moves to the side of the half-threaded block 107 of the first pressing rod 103, they can be combined and fitted. At this time, move the threaded cylinder 108 to the top of the two half-threaded blocks 107 and rotate it.

After tightening, the film will adhere to the inner side surface of the reflector. Then, in the same way, fix one side of other groups of films through the first pressing rod 103, and the fixing of the film by the reflector can be realized, improving the efficiency of film fixing.

[0032] Embodiment 2:

[0033] As Figure 3 and Figure 5 shown in the technical solution, the present invention provides the following technical solution: To solve the problem that the extrusion mechanism of the reflector is unstable and easily causes the film to be loose, on the basis of Embodiment 1, a limiting mechanism is disclosed:

The limiting mechanism includes a compression groove 113, and the compression groove 113 is opened on the upper surface of the rotating block 102. A compression block 114 rotates inside the compression groove 113. A first spring 115 is connected between the compression block 114 and the compression groove 113. A toothed ring 116 is fixed to the bottom of the first pressing rod 103. When the extrusion mechanism of the reflector is in use, the first pressing rod 103 can rotate at the top of the rotating block 102 through a bearing. When the first pressing rod 103 rotates, it can drive the toothed ring 116 to rotate. When the toothed ring 116 rotates, the teeth at the bottom can squeeze the tooth inclined surface of the compression block 114. When the compression block 114 is squeezed, it can rotate through the compression groove 113. When the compression groove 113 rotates, it can squeeze the first spring 115. When the compression block 114 is squeezed to the bottom of the teeth of the toothed ring 116, the first pressing rod 103 can rotate. When the first pressing rod 103 rotates, it can tighten the film. After the first pressing rod 103 rotates to a specified position, the first spring 115 can push the compression block 114 to reset by its own elastic force. When the compression block 114 resets, it can position the toothed ring 116, thereby preventing the first pressing rod 103 from rotating when the film is affected by an external force, and improving the stability when the film is tightened.

[0035] Embodiment 3:

Insert blocks 207 are symmetrically fixed to the left and right sides of the bottom of the cover body 1. A engaging groove 208 is formed on the side surface of the insert block 207. The engaging groove 208 is engaged with the engaging blocks 205. Slots 209 are penetrated and formed on both sides of the rotating groove 201. When the reflector needs to be installed, the rotating block 202 can be rotated through the rotating groove 201. When the rotating block 202 rotates, it can drive the winding disc 203 to rotate. When the winding disc 203 rotates, it can wind the pull rope 204. When the pull rope 204 is wound, both ends can pull the engaging blocks 205 to move. When the engaging blocks 205 move, they can slide through the rotating groove 201. When the engaging blocks 205 slide, they can elastically squeeze the second spring 206. When the engaging blocks 205 are squeezed into the rotating groove 201, the cover body 1 is moved. When the cover body 1 moves, it can drive the insert blocks 207 to move. When the insert blocks 207 move to the top of the slots 209, they can be inserted. When the insert blocks 207 are inserted into the slots 209, they can drive the engaging grooves 208 to move to the side of the engaging blocks 205. At this time, when the rotating block 202 is released, the self-elastic force of the second spring 206 can push the engaging blocks 205 to reset. When the engaging blocks 205 reset, they can be engaged and positioned with the engaging grooves 208. When the engaging grooves 208 are positioned, they can drive the cover body 1 to be installed with the base 2, improving the installation efficiency of the reflector and facilitating later maintenance at the same time.
