Description

Technical Field

[0001] This utility model relates to the field of lens technology, and in particular to a linear laser zoom lens with multi-directional positioning and anti-detachment. Background Technology

[0002] A linear laser zoom lens is a lens device that can continuously or in stages zoom the laser spot on the target surface (i.e., change the size, shape, or degree of focus of the spot) through internal structural adjustments. Its core feature is the use of optical principles to dynamically adjust the linear laser to meet the measurement, scanning, or imaging needs under different distances or scenarios.

[0003] Existing lenses only support simple focal length adjustment and cannot achieve multi-directional adjustment. This limitation may restrict the application of existing lenses in complex scenarios and fail to meet the diverse needs for laser optical paths or imaging perspectives. Utility Model Content

[0004] The purpose of this invention is to provide a multi-directional positioning and anti-detachment linear laser zoom lens. This device facilitates multi-directional adjustment of the lens, thus solving the problem of inconvenient multi-directional adjustment of the lens in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-directional positioning and anti-detachment linear laser zoom lens includes an upper base, with multiple mounting blocks fixedly connected to the side wall of the upper base, a ring plate rotatably connected inside the upper base, and a turntable fixedly connected to the lower end of the ring plate; and a bracket, fixedly mounted at the lower end of the turntable, with a movable block slidably connected inside the bracket, a shaft rotatably connected to the side wall of the movable block, a rotating column fixedly connected to the end of the shaft, a groove provided at the end of the rotating column, a protrusion slidably connected inside the groove, a lens fixedly connected to the end of the protrusion, and an electromagnet fixedly connected to the inner wall of the groove, the electromagnet cooperating with the protrusion.

[0007] Preferably, a motor is fixedly connected to the top of the upper seat, and a gear is rotatably connected inside the upper seat, with the motor output end fixedly connected to the upper end of the gear.

[0008] Preferably, a plurality of tooth blocks are fixedly connected to the inner wall of the ring plate, and the plurality of tooth blocks are distributed in a ring array, wherein the tooth blocks cooperate with the side wall of the gear.

[0009] Preferably, the inner wall of the upper seat is provided with an annular groove, and a limiting plate is fixedly connected to the side wall of the annular plate, with the limiting plate slidably connected to the annular groove.

[0010] Preferably, an electric actuator is fixedly connected to the upper end of the bracket, the electric actuator is slidably connected to the turntable, and the output end of the electric actuator is fixedly connected to the upper end of the movable block.

[0011] Preferably, a drive motor is fixedly connected to the side wall of the movable block, and the output end of the drive motor is fixedly connected to the end of the shaft through a coupling.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. The radial displacement of the lens is limited by the mechanical cooperation between the protrusion and the groove. The magnetic attraction generated by the electromagnet after it is energized further fixes the lens, preventing it from falling off due to vibration, gravity or external force during the adjustment process.

[0014] 2. Through the coordinated action of the motor, electric actuator and drive motor, the lens can be flexibly adjusted in horizontal angle, vertical angle and vertical position, which meets the diverse needs of laser optical path or imaging angle in complex scenes, and also significantly improves the adaptability and compatibility of the system.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A multi-directional positioning and anti-detachment linear laser zoom lens includes an upper base 001, with multiple mounting blocks 101 fixedly connected to its side wall. An annular plate 104 is rotatably connected inside the upper base 001, and a turntable 106 is fixedly connected to the lower end of the annular plate 104. A bracket 002 is fixedly mounted on the lower end of the turntable 106. A movable block 202 is slidably connected inside the bracket 002. A shaft 204 is rotatably connected to the side wall of the movable block 202. A rotating column 205 is fixedly connected to the end of the shaft 204. A groove 206 is provided at the end of the rotating column 205. A protrusion 208 is slidably connected inside the groove 206. A lens 207 is fixedly connected to the end of the protrusion 208. An electromagnet 209 is fixedly connected to the inner wall of the groove 206, cooperating with the protrusion 208. The protrusion 208 is made of iron. The operator designates the upper base 001 to be inside the equipment. The upper end contacts the top of the equipment. Then, the operator inserts bolts through the mounting block 101 to fix the upper seat 001 to the top of the designated equipment. The operator then slides the protrusion 208 at the end of the lens 207 into the groove 206. The side wall of the protrusion 208 fits against the electromagnet 209. Then, the electromagnet 209 is energized to generate magnetic force, attracting the protrusion 208, thereby fixing the lens 207. When the lens 207 needs to be adjusted, the ring plate 104 drives the lens 207 to adjust its horizontal position through the turntable 106, the bracket 002 and the rotating column 205. Then, the shaft 204 drives the rotating column 205 to rotate, adjusting the angle of the lens 207 in the longitudinal position. Then, the movable block 202 drives the lens 207 to adjust its longitudinal displacement through the shaft 204 and the rotating column 205, thus facilitating multi-directional adjustment of the lens 207.

[0022] A motor 102 is fixedly connected to the top of the upper seat 001. A gear 103 is rotatably connected inside the upper seat 001. The output end of the motor 102 is fixedly connected to the upper end of the gear 103. The gear 103 is a spur gear.

[0023] Multiple toothed blocks 105 are fixedly connected to the inner wall of the ring plate 104. The multiple toothed blocks 105 are arranged in a ring array. The toothed blocks 105 cooperate with the side wall of the gear 103. The toothed blocks 105 are straight toothed blocks that match the side wall of the gear 103. When the gear 103 rotates, the ring plate 104 rotates through the cooperation between the toothed blocks 105 and the gear 103.

[0024] The inner wall of the upper seat 001 is provided with an annular groove 107. The side wall of the annular plate 104 is fixedly connected with a limiting plate 108. The limiting plate 108 is slidably connected to the annular groove 107. Through the cooperation between the annular plate 104 and the annular groove 107, the annular plate 104 is limited to prevent the annular plate 104 from falling out of the upper seat 001.

[0025] An electric push rod 201 is fixedly connected to the upper end of the bracket 002. The electric push rod 201 is slidably connected to the turntable 106. The output end of the electric push rod 201 is fixedly connected to the upper end of the movable block 202. The movable block 202 is pushed or pulled up and down by the output end of the electric push rod 201.

[0026] A drive motor 203 is fixedly connected to the side wall of the movable block 202. The output end of the drive motor 203 is fixedly connected to the end of the shaft 204 through a coupling. The shaft 204 is driven to rotate by the output end of the drive motor 203. Both the drive motor 203 and the motor 102 are stepper motors with self-locking function.

[0027] In this utility model, the operator sits on the designated equipment 001, with the upper end of the upper seat 001 contacting the top of the equipment. The operator then inserts a bolt through the mounting block 101 to fix the upper seat 001 to the top of the designated equipment. The operator then slides the protrusion 208 at the end of the lens 207 into the groove 206. The side wall of the protrusion 208 fits against the electromagnet 209. The electromagnet 209 is then energized to generate magnetic force, attracting the protrusion 208, thereby fixing the lens 207 and preventing the lens 207 from falling off the side wall of the rotating column 205 during adjustment.

[0028] When the lens 207 needs to be adjusted, the output end of the motor 102 drives the gear 103 to rotate. Through the cooperation between the gear block 105 and the gear 103, the ring plate 104 rotates. The ring plate 104 drives the lens 207 to adjust its horizontal position through the turntable 106, the bracket 002 and the rotating column 205. After the lens 207 is adjusted horizontally, the output end of the electric push rod 201 pushes the movable block 202 to slide downward. The movable block 202 drives the lens 207 to adjust its vertical displacement through the shaft 204 and the rotating column 205. After the lens 207 is adjusted vertically, the output end of the drive motor 203 drives the shaft 204 to rotate. The shaft 204 drives the rotating column 205 to rotate, thereby adjusting the angle of the lens 207 in the vertical position. Thus, the lens 207 can be adjusted in multiple directions, including horizontal angle, vertical angle and vertical position.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
