Detailed Description of the Embodiment

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides: a device for evaluating the ranging ability of a laser ranging device, as Figures 1 - 6 shown, which includes an absorbing material plate 1. Two groups of mounting disks 9 are symmetrically and movably installed on the upper and lower sides of the front side of the absorbing material plate 1. A group of reflecting mirrors 10 are respectively installed on the corresponding sides of the two groups of mounting disks 9. A group of adjusting components 32 are respectively installed on the left and right sides of the two reflecting mirrors 10 on the front side of the absorbing material plate 1. The adjusting component 32; the adjusting component 32 includes a moving block 13 slidably installed inside the absorbing material plate 1, and a positioning sleeve 18 rotatably installed at the outer end of the moving block 13. A limiting frame 20 is inserted and installed inside the positioning sleeve 18. Two groups of elastic buckles 26 are respectively installed on the upper and lower surfaces of the outer surface of the limiting frame 20; among them, an optical attenuator 27 is clamped and installed inside the lower elastic buckle 26 on the left side of the limiting frame 20 of the reflecting mirror 10, and a collimator 28 is clamped and installed inside the lower elastic buckle 26 on the left side of the limiting frame 20 of the reflecting mirror 10, and a diffusing lens group 29 is clamped and installed inside the upper elastic buckle 26 on the right side of the limiting frame 20 of the reflecting mirror 10, and a limiting column 30 is clamped and installed inside the lower elastic buckle 26 on the right side of the limiting frame 20 of the reflecting mirror 10.

[0027] Preferably, two groups of limiting grooves 2 are symmetrically penetrated through the left and right sides of the surface of the absorbing material plate 1. A positioning rod 3 is fixedly installed in the middle of each group of limiting grooves 2. A number of limiting beads 4 are equidistantly installed on the upper and lower sides inside each group of limiting grooves 2. The absorbing material plate 1 is used to absorb the surrounding light sources, so that the light emitted by the optical attenuator 27 and the collimator 28 can be more intuitively detected, and the light path formed by the refraction of the light through the reflecting mirror 10 can be more easily captured. The limiting grooves 2 opened on both sides of the absorbing material plate 1 are used to limit the moving block 13. The positioning rod 3 installed in the middle of the limiting groove 2 and the limiting beads 4 installed on the inner wall of the limiting groove 2 are both for limiting the movement of the moving block 13, so that the movement process of the moving block 13 is more stable.

[0028] Furthermore, an electric driver 5 is fixedly installed at the center of the rear side of the absorbing material plate 1. A group of lead screws 6 are respectively key-connected to the upper and lower output ends of the electric driver 5. A group of positioning plates 7 are respectively installed at the positions corresponding to the ends of the two lead screws 6 on the rear side of the absorbing material plate 1, and the ends of the lead screws 6 are rotatably installed inside the positioning plates 7. The electric driver 5 installed on the rear side of the absorbing material plate 1 controls the rotation of the lead screws 6. By controlling the lifting of the adjusting frame 11 through the rotation of the lead screws 6, the two reflecting mirrors 10 are synchronously moved, so that the refraction path of the light of the device can be controlled, and the use quality of the device is improved.

[0029] Further, a set of elevation adjusters 11 are fixedly installed outside each installation disc 9. The elevation adjusters 11 are in threaded connection with the screw rod 6 by fitting on the surface of the light-absorbing material plate 1. A chute 12 is provided at the position corresponding to the positioning plate 7 at the rear side of the elevation adjuster 11. The elevation adjusters 11 are located outside the two installation discs 9, so that when the installation discs 9 are limited, the light path will not be affected. The chute 12 provided at the rear side of the elevation adjuster 11 is used to avoid the positioning plate 7. At the same time, the movement of the elevation adjuster 11 can be further limited by the positioning plate 7, so that the two reflecting mirrors 10 can move more stably and synchronously.

[0030] It should be noted that a through hole 14 is provided through the center of the moving block 13. A number of elastic ball beads 15 are elastically installed on the upper and lower sides of the moving block 13 respectively. A damping telescopic rod 16 is fixedly installed at the center of the front side of the moving block 13. The telescopic end of the damping telescopic rod 16 is fixedly installed with a connecting disc 17. The positioning rod 3 is installed through the through hole 14. The elastic ball beads 15 are elastically clamped with the limiting ball beads 4. The through hole 14 provided at the center of the moving block 13 cooperates with the positioning rod 3, and the elastic ball beads 15 installed on the upper and lower sides of the moving block 13 cooperate with the limiting ball beads 4, so that the whole moving block 13 can move stably and stop stably, and the optical attenuator 27, the collimator 28, the diffusing lens group 29 and the diffuse reflection material plate 31 used under limitation can be more stable.

[0031] Specifically, the connecting disc 17 is rotatably installed at the rear side of the positioning sleeve 18. A tightening bolt 19 is threadedly installed at the front side of the positioning sleeve 18. The end of the tightening bolt 19 is movably abutted against the limiting frame 20. The damping telescopic rod 16 installed outside the moving block 13 can control the use position of the positioning sleeve 18, so as to adjust the position of the light emitted to the reflecting mirror 10. And due to the rotational connection property between the connecting disc 17 and the positioning sleeve 18, the use angles of the optical attenuator 27 and the collimator 28 or the diffusing lens group 29 and the diffuse reflection material plate 31 can be adjusted. However, since each set of elastic buckles 26 are limited by the limiting frame 20, the optical attenuator 27, the collimator 28, the diffusing lens group 29 and the diffuse reflection material plate 31 all maintain the same horizontal position, improving the test accuracy.

[0032] In addition, a group of baffles 21 are respectively installed on the upper and lower sides of the limit frame 20, and adjustment teeth 22 are respectively provided on the front and rear sides of the limit frame 20. Two sliding plates 23 are movably sleeved outside the limit frame 20. A socket 24 is provided inside the sliding plate 23. Biting teeth 25 are fixedly installed on the inner wall of the socket 24 corresponding to the position of the adjustment teeth 22. Elastic buckles 26 are installed on the outer surface of the sliding plate 23. The adjustment teeth 22 provided on the front and rear sides of the limit frame 20 cooperate with the biting teeth 25 provided inside the socket 24, so that the independent sliding plates 23 can move to lift the positions of one or more of the optical attenuator 27, the collimator 28, the diffusing lens group 29, and the diffuse reflection material plate 31, so as to make more targeted adjustments according to actual use requirements.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
