Description

Technical Field

[0001] The utility model relates to the technical field of a special device for disassembling lenses of a laser rangefinder, in particular to a special device for disassembling the lenses of a laser rangefinder. Background Art

[0002] Among various production equipment used in cigarette cut tobacco production, such as stackers, case turnover machines, etc., in order to ensure the stability and continuity of cut tobacco production work, laser rangefinder equipment is widely used. The production equipment is centrally placed in the workshop, and the laser rangefinder is often installed at a position not far from the cut tobacco raw materials, resulting in a closed working environment for the laser rangefinder, with a lot of impurities such as dust and cut tobacco filaments and adhesiveness. After the laser rangefinder works for a period of time, impurities such as dust and cut tobacco filaments will adhere to the laser lens of the laser rangefinder, thereby affecting the accuracy of the laser rangefinder to emit and receive laser, and affecting the continuity and stability of cigarette cut tobacco production. Therefore, after the laser rangefinder works for a period of time, it is necessary to manually take out the lens, clean and maintain the lens, wipe it clean and then reinstall it to ensure the stability of the laser rangefinder.

[0003] Since the lens of the laser rangefinder is fixed by pressing the lens through a cover plate using a threaded connection, and the cover plate and the lens are placed inside the housing of the laser rangefinder, it is difficult to take out the cover plate and the lens. During the actual maintenance process, the staff often uses the tools at hand to take out the lens. The sizes of these tools do not match, either too large or too small, and it takes a lot of time to take out the lens. During this process, if not careful, the lens will be scratched, leaving traces that are difficult to repair on the surface of the lens. Even if the method is improper, the lens will be damaged. As one of the key components of the laser rangefinder, once damaged, it will not only affect the measurement accuracy, but also may cause the entire device to fail to work properly, and only a new laser rangefinder can be replaced, resulting in waste of resources and increase in cost. Summary of the Invention

[0004] To solve the many problems in the above-mentioned background art, the purpose of the utility model is to provide a special device for disassembling the lens of a laser rangefinder, to overcome the technical problems in the prior art such as long time-consuming, difficult to disassemble, and easy to damage due to improper methods when disassembling the lens, and to achieve the purposes of efficiently taking out the lens with high function, simple operation, safety and quickness. Specifically, the utility model realizes the above technical purposes by adopting the following design structure and the following technical solutions:

[0005] A special device for disassembling the lens of a laser rangefinder, comprising:

[0006] A cage, the cage having a triangular structure with two hypotenuses symmetrically inclined but not in contact, for installing a suction cup assembly 4 and disassembling the lens 7;

[0007] Rotating rod, the rotating rod is in the shape of a cylinder with an internal through-hole, and a limiting protrusion is provided on the outside. The lower half of the limiting protrusion is a threaded rod, and the upper half of the limiting protrusion is a cylindrical rod. A button is movably connected to the top of the cylindrical rod;

[0008] Tensioning block, the tensioning block is fixedly welded with a hexagonal nut for connecting the built-in threaded rod. Convex platform-shaped holes are provided at the left and right ends of the tensioning block for restricting the hypotenuse of the adjusting cage;

[0009] Suction cup assembly, the suction cup assembly passes through the tensioning block and is fixedly connected to the cage through a nut for stably sucking the lens of the laser rangefinder;

[0010] Further, the through-hole is arranged at the center position of the parallel side of the cage for connecting the rotating rod. Threaded holes are symmetrically arranged on the left and right sides of the through-hole for connecting the suction cup assembly. A parallel side is provided at the front end of the hypotenuse of the cage, and a rubber holder is fixedly connected to the front end of the parallel side;

[0011] Further, the rubber block is fixedly adhered to the outer side surface of the rubber holder with strong glue for clamping and fixing the lens cover plate of the laser rangefinder.

[0012] Further, the rotating rod includes:

[0013] Threaded rod, the threaded rod is arranged in the lower half of the limiting protrusion, and an internal threaded hole is arranged inside the threaded rod for connecting the tensioning block;

[0014] Cylindrical rod, the cylindrical rod is the upper half of the limiting protrusion. Grips are symmetrically arranged on the left and right sides at the top of the cylindrical rod, and L-shaped sliding grooves are arranged on the front and rear sides for the sliding movement and locking position of the button;

[0015] Button, the button is arranged in the through-hole of the cylindrical rod, and limiting rods are fixedly arranged on the front and rear arc surfaces for restricting the sliding direction of the button and playing a locking role;

[0016] Further, the tensioning nut is sleeved on the threaded rod and contacts the lower end surface of the parallel side of the cage. The limiting protrusion included in the rotating rod contacts the upper end surface of the parallel side of the cage. The tensioning nut is used to fix the position of the rotating rod on the cage.

[0017] Further, the tensioning block includes: through-hole Ⅰ, through-hole Ⅱ and convex platform-shaped hole. Through-hole Ⅰ is arranged at the center position of the tensioning block, and a hexagonal nut is fixedly welded to the top surface position of through-hole Ⅰ; Through-hole Ⅱ is symmetrically arranged on the left and right sides of through-hole Ⅰ; The convex platform-shaped hole is arranged at the left and right end positions of the tensioning block for restricting the hypotenuse of the adjusting cage.

[0018] Further, the top end of the built-in threaded rod is screwed into the internal threaded hole of the rotating rod, and the tail end is screwed into the hexagonal nut and fixedly connected to the tensioning block. During use, when the rotating rod is rotated, the rotational movement of the built-in threaded rod is restricted by the inclined sides of the cages at both ends of the tensioning block. Therefore, the built-in threaded rod can only move back and forth, thereby driving the tensioning block to move back and forth.

[0019] Further, the convex platform-shaped holes included in the tensioning block are used to limit the two inclined sides of the adjustment cage. When the tensioning block moves back and forth driven by the built-in threaded rod, the two inclined sides gather or disperse due to the restriction of the tensioning block, thereby controlling the distance between the rubber frames, so as to achieve the purpose of clamping and fixing or loosening the lens cover plate of the laser rangefinder by the rubber block.

[0023] A spring, which is placed between the push rod and the bottom plate of the U-shaped rod and is used for automatic reset.

[0024] Further, there is no contact connection between the suction cup assembly and the tensioning block. The U-shaped rod passes through the through hole II and is fixedly connected to the cage through a nut. The push rod passes through the through hole I, is placed inside the built-in threaded rod and the rotating rod, and is in contact connection with the key.

[0025] The beneficial effects produced by the present utility model compared with the prior art are as follows:

[0026] 1. A special device for disassembling the lens of a laser rangefinder involved in the present utility model has a simple structure and is convenient and fast to operate. Compared with the traditional method of disassembling the lens, which is time-consuming and laborious, it can complete the disassembly work of the lens in a short time, bringing great convenience to subsequent production and maintenance and other links. During the process of taking the lens, the suction cup assembly can adsorb and fix the lens, effectively ensuring that the lens will not be scratched or damaged during the disassembly process, and ensuring that it always maintains a stable working state during long-term use.

[0027] 2. In the present utility model, the opening size of the hypotenuse of the cage is controlled by the forward and backward movement of the tensioning block, and the forward and backward movement of the tensioning block is governed by the rotational movement of the rotating rod. The staff only needs to rotate the rotating rod to accurately control the opening size of the hypotenuse, thereby regulating the distance between the rubber frames. In this way, the cage can form various opening sizes of different dimensions, so as to meet the requirements of different-sized laser rangefinders when disassembling, maintaining, and replacing the lenses.

[0028] 3. Rubber blocks are adhered to the outer side of the rubber frames of the present utility model. After being in close contact with the inner wall of the cover plate, the friction between the two is effectively increased without damaging the cover plate. During the process of removing the lens, it can ensure that the cover plate continuously rotates in a spiral motion and will not cause damage to the cover plate throughout the process, effectively improving the success rate of removing the lens.

[0029] 4. In the present utility model, the suction cup assembly and the tensioning block cooperate with each other but do not interfere with each other. The suction cup assembly can ensure that the lens remains stable during the disassembly process and ensure that the lens will not be scratched or damaged. The tensioning block can correspondingly adjust the opening size of the cage according to the size of the laser rangefinder, and then firmly hold the cover plate, laying a foundation for the subsequent operation of removing the lens. The suction cup assembly and the tensioning block are used in cooperation, which can significantly improve the disassembly and maintenance work efficiency of the laser rangefinder lens. In this way, the production continuity of the wire-making workshop can be ensured, and the working time and service life of the laser rangefinder can be effectively extended.

[0030] 5. The special device of the present utility model has a simple structure, is convenient to manufacture and use, can meet the requirements of different-sized laser rangefinders when disassembling, maintaining, and replacing the lenses, and is suitable for popularization and use.
