Description

Technical Field

[0001] This utility model relates to the field of photoelectric turntable technology, specifically a limit and stop device for a photoelectric turntable. Background Technology

[0002] CN220749599U discloses a self-adjusting photoelectric turntable, which includes a base, a rotating component on the top of the base, a U-shaped frame fixedly connected to the rotating component, and a photoelectric turntable body fixedly connected to the top of the U-shaped frame. The rotating component includes a drive shaft, the bottom end of which extends into the interior of the base. A rotating shaft is rotatably connected to the bottom of the inner wall of the base. The top end of the rotating shaft and the bottom end of the drive shaft are detachably connected by fastening bolts. A drive assembly for rotating the rotating shaft is provided inside the base, and a locking component for locking the rotating shaft is provided inside the base.

[0003] This technical solution enables the photoelectric turntable to self-adjust by setting up a drive component, and locks the rotating shaft after rotation to ensure its stability after self-adjustment.

[0004] The locking mechanism uses two electric telescopic rods to extend and retract, which in turn drives two arc-shaped anti-slip blocks in opposite or opposite directions. The relative movement of the two arc-shaped anti-slip blocks wraps around the friction wheel, thus forming a friction lock and ensuring the stability of the photoelectric turntable after self-adjustment. However, the applicant found that the locking mechanism in this technical solution uses two electric telescopic rods to extend and retract simultaneously for locking, which is costly. Moreover, the two arc-shaped anti-slip blocks hold the same position on the friction wheel for a long time, which will cause wear on the outside of the friction wheel over time, thus affecting the anti-slip locking ability in the future. Therefore, this technical solution still has shortcomings and needs to be improved. Utility Model Content

[0007] The fixed cylinder is equipped with a reduction motor and a locking component. The reduction motor is used to drive the locking component to tighten or loosen the friction wheel.

[0008] The fixed cylinder is equipped with a lifting component, which is connected to a locking component. The lifting component is used to drive the locking component and the geared motor to lift.

[0009] Preferably, the locking component includes a slide rail, on which a bidirectional lead screw is connected via a bearing. The bidirectional lead screw is connected to the output shaft of a geared motor, and the geared motor is mounted on the slide rail. Two sliders are slidably connected on the slide rail, and the two sliders are respectively screwed to both ends of the bidirectional lead screw.

[0010] Preferably, the friction wheel has friction protrusions evenly distributed around its outer circumference, and the friction protrusions are hemispherical, with anti-slip pads on both sides able to wrap around the friction protrusions.

[0015] Beneficial effects

[0016] This invention provides a limiting and stopping device for an optoelectronic turntable. Compared with the prior art, it has the following advantages:

[0017] 1. This technical solution uses a geared motor to drive a bidirectional lead screw to rotate, allowing the anti-slip pads on both sides to move in opposite directions simultaneously. Compared with existing technologies, this reduces one driving source, thereby lowering the production cost for enterprises. Friction protrusions are evenly arranged on the outer side of the friction wheel, which further increases the friction force when it is wrapped and locked by the anti-slip pad, thus improving the stability of the photoelectric turntable.

[0018] 2. This technical solution uses a lifting component to drive the reduction motor and locking component to lift and lower, so that the locking component does not have to lock one point of the friction wheel all the time, thereby reducing the wear of the friction wheel and improving the locking ability between the anti-slip pad and the friction wheel, thus further improving the stability of the photoelectric turntable and improving the limit stopping ability of the photoelectric turntable.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] See Figures 1-4 This utility model provides the following two technical solutions:

[0026] First embodiment: A limiting and stopping device for a photoelectric turntable includes a base 1, a fixed cylinder 2 is provided on the top of the base 1, a rotating shaft 3 is connected to the fixed cylinder 2 through a bearing, the rotating shaft 3 is connected to a driving component and a mounting frame 4, and the mounting frame 4 is used to install a detector, the driving component includes a gear 5 provided on the rotating shaft 3, a rack 6 is meshed on the gear 5, and the rack 6 is connected to a horizontally arranged electric push rod 7, wherein the output end of the electric push rod 7 is connected to the rack 6, the electric push rod 7 is connected to the inner wall of the fixed cylinder 2, the electric push rod 7 drives the rack 6 to move horizontally, thereby driving the gear 5 to rotate, and a friction wheel 8 is provided on the rotating shaft 3;

[0027] The fixed cylinder 2 is equipped with a geared motor 11 and a locking component. The geared motor 11 is used to drive the locking component to tighten or loosen the friction wheel 8. The locking function can be achieved by driving the locking component through the geared motor 11 itself. Compared with the existing technology, one driving source is reduced, thereby reducing the production cost of enterprises.

[0028] In order to change the clamping position of the locking component on the friction wheel 8, a lifting component is provided on the fixed cylinder 2, and the lifting component is connected to the locking component, so that the lifting component can drive the locking component and the reduction motor 11 to rise and fall.

[0029] The locking component includes a slide rail 10, on which a bidirectional lead screw 12 is connected via bearings. The bidirectional lead screw 12 is connected to the output shaft of a geared motor 11, and the geared motor 11 is mounted on the slide rail 10, allowing the geared motor 11 to drive the bidirectional lead screw 12 to rotate. Two sliders 13 are slidably connected on the slide rail 10, and the two sliders 13 are respectively screwed to both ends of the bidirectional lead screw 12. Semi-circular anti-slip pads 14 are provided on the opposite sides of the two sliders 13. When the bidirectional lead screw 12 rotates, the two sliders 13 move laterally simultaneously under the guidance of the slide rail 10.

[0030] In order to improve the friction capability of the friction wheel 8, friction protrusions 9 are evenly distributed around the outer side of the friction wheel 8, and the friction protrusions 9 are hemispherical. The anti-slip pads 14 on both sides can be wrapped around the friction protrusions 9.

[0031] The lifting component includes a metal block 15 connected to the slide rail 10. The metal block 15 is slidably connected to the guide rail 16 connected to the inner wall of the fixed cylinder 2, which is used to guide the slide rail 10 when it is raised or lowered. The top of the metal block 15 is connected to a screw 17 through a bearing, and the top of the screw 17 is connected to the top of the fixed cylinder 2 through a thread. The top of the screw 17 extends above the fixed cylinder 2. A handwheel 18 is provided on the top of the screw 17. By manually rotating the handwheel 18, the screw 17 can be rotated on the fixed cylinder 2, thereby causing the metal block 15 to be raised or lowered under the guidance of the guide rail 16.

[0032] For ease of maintenance, a through groove 20 is provided on the fixed cylinder 2, and a maintenance plate 21 is provided at the through groove 20. Screw mounting structures 22 that connect to the fixed cylinder 2 are provided around the maintenance plate 21, and a handle 23 is provided on the maintenance plate 21.

[0033] To facilitate leveling of the photoelectric turntable, a waist-shaped hole 24 is provided around the base 1, and an adjustable support foot 25 is provided on the waist-shaped hole 24.

[0034] The second implementation differs from the first implementation in that an electromagnet plate 19 is provided on the guide rail 16, and the electromagnet plate 19 is in contact with the metal block 15, wherein the electromagnet plate 19 is energized by existing technology.

[0035] When the electromagnet plate 19 is energized, the metal block 15 can be attracted and fixed, thereby improving the stability of the slide rail 10 and preventing the handwheel 18 from being accidentally rotated when it is not in use.

[0036] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0037] In use, the rotating shaft 3 is adjusted by the drive component. After adjustment, the reduction motor 11 drives the anti-slip pads 14 on both sides to grip the friction wheel 8 and the friction protrusions 9 on the surface. When the friction wheel 8 and the friction protrusions 9 on the surface are worn excessively, the electromagnet plate 19 can be de-energized, and the handwheel 18 can be rotated to make the anti-slip pads 14 move downward to grip the friction wheel 8 and the lower side of the friction protrusions 9 on the surface to ensure locking ability. Finally, the electromagnet plate 19 is energized to attract and fix the metal block 15, thus completing the reinforcement of the handwheel 18.
