Description

Technical Field

[0001] This utility model belongs to the field of lens impact testing technology, and in particular relates to a lens impact testing device. Background Technology

[0002] With the diversification of entertainment facilities, people's entertainment options have also diversified, greatly enriching their leisure life. People can improve their mood and relax their tense minds and bodies through entertainment. Moreover, these happy moments are worth recording and preserving, which brings us to the video camera. Video cameras can record people's entertainment activities, making it convenient for people to relive these heartwarming moments later. The components of a video camera include a power system, viewfinder, body, storage device, image sensor, and lens. The lens is mainly used to collect light and form an optical image. It is composed of multiple convex and concave lenses. By adjusting the focal length and aperture, the image clarity is controlled. Before the lens is put into use, it needs to undergo an impact test to check whether its internal structure is loose when subjected to impact, and to determine whether the lens quality is up to standard.

[0003] However, the lens impact testing device still has the following drawbacks in actual use:

[0004] 1. First, a movable platform is set on the base. Threaded holes are equidistantly opened on the movable platform, and molds are also equidistantly placed on the movable platform. During the process of connecting the movable platform and the molds, the workers place the molds on the movable platform and align them with the threaded holes. They then use a screwdriver to turn the screws on the molds clockwise to fix the molds on the movable platform. During the process of disassembling the movable platform and the molds, it is still necessary to use a screwdriver to turn the screws on the molds. Therefore, the workers need to rely on a screwdriver during the disassembly and assembly of the movable platform and the molds. If the screwdriver is lost, it is impossible to disassemble and assemble the movable platform and the molds.

[0005] 2. Next, the mold is fixed on the movable table. The staff inserts the lens base into the mold and uses a screwdriver to rotate the four screws on the lens base in turn to fix the lens on the mold, which increases the stability of the lens and allows for a smooth impact test. When unloading the lens, it is still necessary to use a screwdriver to remove the four screws in turn, which increases the steps in loading and unloading the lens, increases the workload, and reduces the efficiency of the lens impact test.

[0006] To address these issues, we provide a lens impact testing device. Utility Model Content

[0007] The purpose of this utility model is to provide a lens impact testing device. By setting up a clamping component, the operation steps of loading and unloading lenses are simplified, the workload is reduced, and the efficiency of lens impact testing is accelerated. Furthermore, by setting up a connecting component, the assembly and disassembly between the fixing clamp and the mounting plate are facilitated, thereby solving the technical problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model relates to a lens impact testing device, comprising a movable platform. A clamping assembly is provided on the upper surface of the movable platform. The clamping assembly includes a rectangular array of supports fixed to the four corners of the lower surface of a mounting plate. The supports are connected to the upper surface of the movable platform. A rectangular array of connecting blocks is connected to the upper surface of the mounting plate. A fixed clamping block is fixed to the side wall of a support block fixed to the side wall of the connecting block. A movable clamping block is hinged to the side wall of the fixed clamping block. A bolt threaded to the side wall of the movable clamping block is threadedly connected to the fixed clamping block. A connecting assembly is provided on the lower surface of the mounting plate. The connecting assembly includes a protruding rod connected to the lower surface of the connecting block. The protruding rod penetrates the mounting plate. A strip plate is threaded to the peripheral side wall of a screw fixed to the lower surface of the mounting plate. A limiting block is fixed to the side wall of the strip plate. A notch is formed on the side wall of the protruding rod, and the limiting block abuts against the inside of the notch.

[0010] The present invention is further configured such that a base is provided on the lower surface of the movable platform, a base plate is provided on the lower surface of the base, and a damping spring is sleeved on the peripheral side wall of a damper connected in a rectangular array on the side wall of the base, and the lower surface of the damper is connected to the upper surface of the base plate.

[0011] The present invention is further configured such that a rectangular array of connecting cylinders are connected to the side wall of the base, and a connecting rod is sleeved inside the connecting cylinder, with the lower end of the connecting rod connected to the upper surface of the substrate.

[0012] The present invention is further configured such that a top platform is provided above the movable platform, and guide posts are installed at the four corners of the lower surface of the top platform, with the lower ends of the guide posts penetrating the movable platform and installed on the upper surface of the substrate.

[0013] The present invention is further configured such that a driving gear is symmetrically connected to the upper surface of the substrate, a driven gear is symmetrically connected to the lower surface of the top platform, the driving gear and the driven gear mesh together with a toothed belt, a motor is connected to the end of the driving gear, and toothed blocks are symmetrically installed on the two side walls of the movable platform, the toothed blocks meshing with the toothed belt.

[0015] The present invention is further configured such that the thickness of the limiting block is one-third of the depth of the notch, and both the limiting block and the notch are semi-circular structures.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting up a clamping component, allows the movable clamping block to be fixed by rotating the bolt counterclockwise, placing the lens on the connecting block and releasing it from the fixed clamping block. The movable clamping block is then closed, and the bolt is rotated clockwise to fix the position of the movable clamping block, locking the lens position and preventing it from moving during impact testing. This ensures a stable impact test. At the same time, the operator only needs to rotate a single bolt to fix and unlock the lens position, simplifying the lens loading and unloading process, reducing workload, and accelerating the efficiency of lens impact testing.

[0018] 2. This utility model, by setting a connecting component, allows the strip plate to be rotated counterclockwise. The strip plate moves in an arc around the screw as a fixed point, and the limiting block moves accordingly, moving out of the notch. This releases the fixation of the protruding rod position, pulls the support block upward, and disassembles the mounting plate and the fixing clamp. Conversely, it assembles the mounting plate and the fixing clamp. There is no need to use a screwdriver to adjust the position of the limiting block, which facilitates the disassembly and assembly of the mounting plate and the fixing clamp.
