Description

Technical Field

[0001] This application relates to the technical field of lenses, and in particular to a lens with an edge protection structure. Background Art

[0002] A lens is an optical element made of a transparent substance (such as glass, crystal, etc.). Convex lens: thick in the middle and thin at the edges, with three types: double convex, plano-convex, and concave-convex; Concave lens: thin in the middle and thick at the edges, with three types: double concave, plano-concave, and convex-concave. Lenses play an important role in fields such as astronomy, military, transportation, medicine, and art.

[0003] Existing lenses, such as double convex lenses, are often used for magnifying objects. A traditional lens is connected with a plastic or metal frame, and a handle rod is fixed on one side of the frame. Although it is convenient to pick up, since the two sides of the double convex lens are convex, and the thickness of the plastic or metal frame is less than the convex surface, when placing the lens, it will cause friction on the convex surface of the lens, and after long-term use, the convex surface of the lens will be worn and scratched, thus unable to be used normally. Utility Model Content

[0004] To solve the problem, this application provides a lens with an edge protection structure.

[0005] A lens with an edge protection structure provided by this application adopts the following technical solutions:

[0006] A lens with an edge protection structure includes a double convex lens, and also includes a protection mechanism and a connecting frame. The protection mechanism is installed at the edge of the double convex lens for external protection of the double convex lens; One side of the protection mechanism is fixed with a mounting sleeve, the middle of the connecting frame is fixed with a circular plate, and an insertion plate is fixed on one side of the circular plate. The insertion plate is inserted into the mounting sleeve, and both ends of the connecting frame are connected to the protection mechanism.

[0007] Preferably, the protection mechanism includes a pair of protection rings sleeved on the edge of the double convex lens, and a tightening ring sleeved on the protection rings. Both protection rings are arc-shaped and are symmetrically distributed and fixed. An embedding groove is opened on the outer side wall of the protection ring, and both tightening rings are arc-shaped and are embedded in the embedding groove.

[0008] Preferably, the mounting sleeve is fixed on one of the tightening rings, and the mounting groove of the mounting sleeve has a chamfer.

[0009] Preferably, a plurality of uniformly distributed support rods are fixed on both the upper and lower sides of the protection ring.

[0010] Preferably, both the protection ring and the support rods are made of plastic material and are integrally formed.

[0011] Preferably, a bolt rod is fixed on the circular sheet, and a hand-held rod is screwed onto the bolt rod.

[0012] Preferably, connecting pieces are fixed at the ends of the two tightening rings. The connecting pieces on the two tightening rings are fitted together and fixed by screwing a hand-tightening bolt.

[0013] In summary, the present application includes the following beneficial technical effects:

[0014] 1. By providing a protective ring, a support rod and a tightening ring, the protective ring can protect the edge of the biconvex lens. The length of the support rod is greater than the height of the convex surface of the biconvex lens, which can prevent the convex surface from contacting the tabletop when placing the biconvex lens, thereby avoiding wear and scratching of the convex surface.

[0015] 2. By providing a tightening ring, a connecting piece, a hand-tightening bolt, a connecting frame and a hand-held rod, damaged or severely worn components can be replaced after long-term use of the biconvex lens. It is convenient to disassemble the biconvex lens for cleaning. Also, these components can be combined with a new biconvex lens multiple times without damage, improving the practicality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes the present application in detail with reference to the Figures 1 - 3 drawings.

[0021] The embodiment of the present application discloses a lens with an edge protection structure. Refer to Figures 1 - 3, A lens with an edge protection structure, including a biconvex lens 1, and further including a protection mechanism and a connecting frame 7. The protection mechanism is installed at the edge of the biconvex lens 1 for external protection of the biconvex lens 1; one side of the protection mechanism is fixed with a mounting sleeve 8, the middle of the connecting frame 7 is fixed with a circular plate 10, and an insertion plate 9 is fixed on one side of the circular plate 10. The insertion plate 9 is inserted into the mounting sleeve 8, and both ends of the connecting frame 7 are connected to the protection mechanism. The protection mechanism includes a pair of protection rings 2 sleeved on the edge of the biconvex lens 1, and a tightening ring 4 sleeved on the protection ring 2. Both protection rings 2 are arc-shaped and are symmetrically distributed and fixed. An embedding groove 13 is opened on the outer side wall of the protection ring 2. Both tightening rings 4 are arc-shaped and are embedded in the embedding groove 13. Connecting pieces 5 are fixed at the ends of both tightening rings 4. The connecting pieces 5 on both tightening rings 4 are fitted together and are screwed and fixed by a hand-tightening bolt 6.

[0022] During use, the staff can hold the hand-held rod 11 to normally use the biconvex lens 1; during assembly, first, put the two protection rings 2 on the biconvex lens 1, and respectively set the tightening rings 4 in the embedding grooves 13 of the two protection rings 2. Subsequently, take the connecting frame 7 and insert the insertion plate 9 into the mounting sleeve 8, and align and fit the two ends of the connecting frame 7 with the connecting pieces 5, and respectively screw the hand-tightening bolt 6 to fix. Finally, screw the hand-held rod 11 tightly on the bolt rod 12 to complete the assembly. The operation is simple, which is convenient for subsequent disassembly, decomposition and replacement of parts, and has high practicability.

[0023] In this embodiment, as Figure 2 and Figure 3 shown, the mounting sleeve 8 is fixed on one of the tightening rings 4, and the mounting groove of the mounting sleeve 8 has a chamfer. This setting can make the insertion plate 9 more smoothly inserted into the mounting sleeve 8, which helps to speed up the installation speed and improve the convenience.

During assembly, first, put two protective rings 2 on the biconvex lens 1, and respectively set tightening rings 4 in the embedding grooves 13 of the two protective rings 2. Subsequently, take the connecting frame 7 and insert the inserting plate 9 into the mounting sleeve 8, and align and fit the two ends of the connecting frame 7 with the connecting pieces 5, and then respectively screw the mounting hand-tightening bolts 6 to fix them. Finally, screw the hand-held rod 11 tightly on the bolt rod 12 to complete the assembly. The operation is simple, which is convenient for subsequent disassembly, decomposition and replacement of parts, and has high practicability.
