Description

Technical Field

[0002] After searching, application number 202223321323.X discloses an adjustable optical lens assembly, including a fixed frame, a fixed block is arranged inside the fixed frame, an adjustment mechanism is arranged above the fixed block, both sides of the fixed block are rotatably connected with locking mechanisms, a support assembly is rotatably connected below the fixed block, a support leg is fixed below the fixed frame, the adjustment mechanism is used to adjust the angle of the fixed block, and the locking mechanism is used to fix the optical lens.

[0003] During use, an adjustable optical lens assembly in the patent application uses a rotating screw to drive a clamp to fix the optical lens inside a fixed block, and then drives the optical lens on the fixed block to rotate by rotating a rotating rod, so as to adjust the angle of the optical lens. However, during such use, the device uses gears B and A to limit the rotating rod and the fixed block to prevent gear A from driving the rotating rod and the fixed block to rotate on their own. However, the meshing between the gears cannot play a self-locking role, and the support plate and the fixed block are not on the same axis, so that the support frame on the support plate cannot rotate synchronously with the fixed block, and the support frame cannot adapt to the bottom of one end of the optical lens to form an effective support effect. In view of the above shortcomings, we propose an adjustable optical lens. Utility Model Content

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides an adjustable optical lens.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an adjustable optical lens, comprising a fixed frame, a fixed block arranged inside the fixed frame, and a fixed assembly arranged at the left and right ends of the fixed block; a first rotating shaft rod and a second rotating shaft rod fixedly connected to the upper and lower ends of the fixed block are respectively rotatably connected in the middle of the upper and lower walls of the inner cavity of the fixed frame; an adjusting mechanism for driving the fixed block to rotate is provided in the middle of the inner side of the top end of the fixed frame; the adjusting mechanism comprises an adjusting worm screw rotatably connected to the left end of the inner cavity of the adjusting cavity; a supporting mechanism is arranged on the second rotating shaft rod; the supporting mechanism comprises a supporting rotating plate fixedly connected to the middle of the front end of the second rotating shaft rod and a supporting frame fixedly installed at the front end of the top wall of the supporting rotating plate; a lifting mechanism is arranged at the bottom of the fixed frame; the lifting mechanism comprises two hollow supporting rods fixedly connected to the bottom wall of the fixed frame and two movable rods slidably connected to the inside of the two hollow supporting rods.

[0006] Furthermore, the top of the first rotating shaft passes through the top wall of the inner cavity of the fixed frame and extends to the inside of the adjustment cavity.

[0007] Furthermore, an adjusting worm wheel meshing with the adjusting worm is fixedly mounted on the outer wall surface of one end of the first rotating shaft located inside the adjusting cavity.

[0008] Furthermore, the front end of the adjusting worm penetrates the front inner wall surface of the adjusting cavity and extends to the outside and is fixedly mounted with an adjusting hand wheel.

[0009] Furthermore, two locking bolts are threadedly installed on the bottom of the outer wall of the two hollow support rods.

[0010] Furthermore, one end of the two locking bolts extends into the interior of the two hollow support rods and is in pressing contact with the corresponding positions of the outer wall surfaces of the two movable rods.

[0011] Furthermore, two supporting feet are fixedly mounted on the bottom ends of the two movable rods.

[0012] Furthermore, a reinforcing connecting rod in a horizontal state is fixedly connected between the middle parts of the outer wall surfaces of the two hollow support rods.

[0013] Beneficial Effects

[0014] The utility model provides an adjustable optical lens, which has the following beneficial effects:

[0015] 1. The adjustable optical lens is provided with an adjustment mechanism and a supporting mechanism. When in use, one end of the optical lens is first placed inside the fixed block, and then the other end of the optical lens is placed on the supporting frame body. The optical lens is fixedly installed inside the fixed block through the fixing assembly. When the angle of the optical lens needs to be adjusted, the adjusting hand wheel is rotated to drive the adjusting worm to rotate, forcing the adjusting worm wheel engaged with the adjusting worm to drive the first rotating shaft rod to rotate. The first rotating shaft rod drives the optical lens to rotate through the fixed block to achieve the adjustment of the angle. The adjusting worm and the adjusting worm wheel have a self-locking ability, which can avoid the situation where the adjusting worm wheel drives the optical lens inside the fixed block to rotate by itself through the first rotating shaft rod. The supporting frame body is connected to the second rotating shaft rod through the supporting rotating plate, so that the supporting frame body can rotate and adjust the position synchronously with the optical lens inside the fixed block, so that the supporting frame body is always in close contact with the optical lens to form a stable supporting effect. The above operation is simple and practical, the structure is reasonable and compact, the device can achieve the stable angle adjustment function and stable supporting effect of the optical lens, and the practicality of the device is improved.

[0016] 2. This adjustable optical lens, by setting a reinforced connecting rod, can complete the fixation between the two hollow support rods and the two movable rods by pulling out the two movable rods from the inside of the two hollow support rods to a suitable length and tightening the two locking bolts, thereby realizing the height adjustment of the optical lens inside the fixed block. In addition, the two hollow support rods are fixedly connected with a reinforced connecting rod, which strengthens the connection between the two hollow support rods and improves the stability of the device structure.
