Description

Technical Field

[0001] The utility model belongs to the technical field of Fresnel lenses, and in particular relates to a novel Fresnel lens. Background Art

[0002] Fresnel lens, also known as threaded lens, has a smooth surface on one side and concentric circles from small to large on the other side. Its texture is designed according to the interference and disturbance of light as well as the relative sensitivity and receiving angle requirements. Fresnel lens has the function of focusing and dividing the detection area into several bright and dark areas. It is mainly used in solar photovoltaic, optical engineering, polymer material engineering, focusing and energy, aviation and navigation and other fields.

[0003] During the application process, the Fresnel lens usually requires a corresponding assembly frame for assembly limitation, and the height and angle of the Fresnel lens need to be adaptively adjusted according to actual conditions. However, most of the Fresnel lenses in the prior art do not have the function of convenient assembly adjustment, which makes the assembly and adjustment process of the Fresnel lens in actual application more cumbersome and complicated, making the application convenience of the Fresnel lens less.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a new type of Fresnel lens.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] like Figures 1 to 6 As shown, a novel Fresnel lens in an embodiment of the utility model comprises: an assembly base 1, a convenient clamping mechanism 2, and an adjustable fixing mechanism 3.

[0031] like Figure 1 As shown, the bottom of the assembly base 1 is fixedly assembled with multiple groups of evenly distributed support legs 101. The assembly base 1 is supported and limited by the multiple groups of support legs 101, thereby ensuring the stability of the assembly base 1 in use.

[0032] like Figures 1 to 3 As shown, the portable clamping mechanism 2 is assembled on the top of the assembly base 1, and the portable clamping mechanism 2 includes a clamping limit plate 201, and the clamping limit plate 201 is assembled on the top of the assembly base 1. The clamping limit plate 201 is used to assemble and limit the Fresnel lens 202.

[0033] like Figures 2 to 3As shown, multiple groups of evenly distributed fixed clamps 205 are fixedly connected to the upper side of the clamping limit plate 201. The multiple groups of fixed clamps 205 are used to assemble and limit the Fresnel lens 202, thereby reducing the possibility of the Fresnel lens 202 falling off during the rotation of the clamping limit plate 201.

[0034] like Figures 2 to 3 As shown, the side of the multiple groups of fixed clamps 205 close to the Fresnel lens 202 is fixedly connected with a protective pad 206. The protective pad 206 improves the effect of the fixed clamps 205 on the Fresnel lens 202, and reduces the situation that the Fresnel lens 202 is broken and damaged by the external force of the fixed clamps 205.

[0035] like Figures 2 to 3 As shown, a Fresnel lens 202 is snap-fitted and assembled inside the clamping limit plate 201 .

[0036] like Figure 5 to Figure 6 As shown, both sides of the clamping and limiting plate 201 are fixedly connected with the assembly shaft 203. The clamping and limiting plate 201 is supported and limited by supporting and limiting the assembly shaft 203.

[0037] like Figures 2 to 6 As shown, a pair of assembly shafts 203 are rotatably assembled with threaded fixing blocks 204 on one side away from the clamping limit plate 201. The assembly shafts 203 are supported and limited by the threaded fixing blocks 204. At the same time, the clamping limit plate 201 can be lifted and lowered by controlling the threaded fixing blocks 204.

[0038] like Figure 5 to Figure 6 As shown, one side of a pair of threaded fixing blocks 204 is threadedly connected with a locking bolt rod 207, and the locking bolt rod 207 is arranged in cooperation with the assembly shaft 203. The assembly shaft 203 is locked and fixed by controlling the rotation of the locking bolt rod 207, so as to facilitate the fixing and limiting of the inclined clamping limit plate 201.

[0039] like Figures 2 to 4 As shown, the adjustable fixing mechanism 3 is fixedly assembled between the clamping limit plate 201 and the assembly base 1, and the adjustable fixing mechanism 3 includes an assembly gear box 301, and the assembly gear box 301 is fixedly assembled above the assembly base 1. The assembly gear box 301 is used to assemble and limit the limit threaded rod 303. At the same time, the assembly gear box 301 can provide a rotation and assembly operation space for the driving pulley 305, the synchronous belt 306, and the double-groove pulley 307.

[0040] like Figure 1 As shown, a loading platform 302 is fixedly mounted above the assembly gear box 301. The loading platform 302 is used to support and limit the objects.

[0041] like Figure 1 to Figure 2 As shown, a plurality of evenly distributed limiting bosses 304 are integrally formed above the loading platform 302. The plurality of limiting bosses 304 are used to limit the position of the articles placed on the loading platform 302, thereby improving the reliability of the loading platform 302 in supporting and limiting the articles.

[0042] like Figure 1 to Figure 2 As shown, limiting threaded rods 303 are arranged on both sides of the stage 302, and the limiting threaded rods 303 are rotatably assembled on both sides of the assembly gear box 301. A pair of limiting threaded rods 303 are both arranged through the threaded fixing block 204, and a pair of limiting threaded rods 303 are threadedly connected with the threaded fixing block 204.

[0043] like Figures 2 to 4 As shown, one end of a pair of limiting threaded rods 303 located in the assembly gear box 301 is fixedly connected to a driving pulley 305. The limiting threaded rods 303 are rotationally driven by controlling the rotation of the driving pulley 305, so that the threaded fixing block 204 is raised and lowered with the rotation of the limiting threaded rods 303 under the action of the internal and external threads, thereby playing a role in adjusting the height of the Fresnel lens 202.

[0044] like Figures 2 to 4 As shown, a synchronous belt 306 is sleeved on the outer side of the driving pulley 305. The synchronous belt 306 serves to connect the driving pulley 305 with the double groove pulley 307, so that the driving pulley 305 rotates synchronously with the rotation of the double groove pulley 307 under the action of the synchronous belt 306.

[0045] like Figures 2 to 4 As shown, a double groove pulley 307 is connected to one side of the synchronous belt 306 away from the driving pulley 305. The synchronous belt 306 is moved and controlled by the double groove pulley 307, so that the driving pulley 305 is driven and controlled.

[0046] like Figures 2 to 4 As shown, a limit rotation shaft 308 is fixedly connected inside the synchronous belt 306, and the limit rotation shaft 308 is rotatably assembled in the assembly gear box 301. The limit rotation shaft 308 plays the role of assembly limit for the synchronous belt 306.

[0047] like Figures 2 to 4 As shown, a driving worm gear 309 is fixedly mounted below the limit rotation shaft 308. The limit rotation shaft 308 is rotationally driven by controlling the driving worm gear 309 to rotate.

[0048] like Figures 2 to 4As shown, a transmission worm 310 is meshed on one side of the driving worm wheel 309. The driving worm wheel 309 is rotationally driven by controlling the rotation of the transmission worm 310. At the same time, the limit rotation shaft 308 is locked and limited by the self-locking function of the driving worm wheel 309 and the transmission worm 310.

[0049] like Figures 2 to 4 As shown, a driving shaft 311 is fixedly connected inside the transmission worm 310. The driving shaft 311 plays the role of supporting, fixing and rotating the transmission worm 310.

[0050] like Figure 1 As shown, one end of the driving shaft 311 outside the assembly gear box 301 is fixedly connected with a driving hand wheel 312. The driving shaft 311 is driven to rotate by controlling the rotation of the driving hand wheel 312, so as to facilitate driving control of the transmission worm 310.

[0051] When used specifically, the Fresnel lens 202 can be placed in the clamping and limiting plate 201, and the Fresnel lens 202 can be supported and limited by the clamping and limiting plate 201. At the same time, the Fresnel lens 202 can be clamped and limited by controlling multiple sets of fixed clamping plates 205 and protective pads 206, so that the Fresnel lens 202 can be conveniently clamped.

[0052] When the Fresnel lens 202 needs to be angle-adjusted, the locking state of the assembly shaft 203 is released by controlling the operation of the locking bolt rod 207. Subsequently, the angle of the clamping limit plate 201 can be manually adjusted. After the angle is adjusted, the locking bolt rod 207 is controlled to rotate so that the locking bolt rod 207 locks and fixes the assembly shaft 203, thereby limiting the angle of the clamping limit plate 201.

[0053] When the height of the Fresnel lens 202 needs to be adjusted, the driving shaft 311 is rotated by controlling the rotation of the driving hand wheel 312 so that the driving shaft 311 can rotationally drive the driving worm gear 309. The limiting shaft 308 drives the double-groove pulley 307 to rotate under the driving action of the driving worm gear 309. A pair of limiting threaded rods 303 rotate synchronously with the rotation of the double-groove pulley 307 under the action of the driving pulley 305 and the synchronous belt 306. When the limiting threaded rod 303 rotates, the threaded fixing block 204 drives the clamping limiting plate 201 to move up and down under the action of the internal and external threads, thereby adjusting the height of the Fresnel lens 202, simplifying the convenience of clamping and adjusting the Fresnel lens 202.

[0054] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
