Description

Technical Field

[0001] This utility model relates to the field of laser level technology, specifically to an angle adjustment bracket for a laser level. Background Technology

[0002] Angle adjustment brackets for laser levels, also known as laser level fine-tuning bases, are mostly manual in design. Their structure generally includes a base, support feet, a rotating frame, a knob, and a transmission mechanism. The knob, rotating frame, and transmission mechanism are connected. The laser level is fixed to the top of the rotating frame. Turning the knob drives the rotating frame to rotate via the transmission mechanism, allowing the laser level to rotate, as shown in CN219734794U. Alternatively, there are electrically operated angle adjustment brackets for laser levels, such as the high-reliability laser level disclosed in CN216283510U. Electric control is more labor-saving than manual control, but the electric structure cannot function properly when the power supply is unavailable or damaged. Manual control does not have this drawback. Therefore, developing an angle adjustment bracket for laser levels that combines both manual and electric functions is a research direction desired by those skilled in the art. Utility Model Content

[0005] Furthermore, a first fixed plate is fixed inside the rotating frame, the motor is fixed on the first fixed plate, the end of the first worm gear away from the motor has a first rotating shaft, one end of the first fixed plate has a shaft seat, the first rotating shaft is inserted into the shaft seat and rotates with the shaft seat.

[0006] Furthermore, a second fixed plate is fixed inside the rotating frame, and a second rotating shaft extending vertically is fixed on the second fixed plate, with the first gear sleeved outside the second rotating shaft.

[0007] Furthermore, a retaining ring is fixed at the bottom of the second rotating shaft, and the retaining ring blocks the bottom of the first gear.

[0008] The advantages of using the angle adjustment bracket for laser level provided by this utility model are: it has both manual and electric adjustment functions. When adjusting manually, you can turn the knob by hand, and when adjusting electrically, it is controlled by a motor, which makes it convenient to use under different usage needs.

Detailed Implementation

[0013] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:

[0014] like Figure 1 — Figure 3 As shown, the laser level uses an angle adjustment bracket, which includes a base 11. Multiple support feet 2 are installed at the bottom of the base 11. A rotating frame 12 is covered on the upper end of the base 11. The base 11 and the rotating frame 12 form a housing 1. A motor 3, a first worm gear 4, a first gear 5, a second gear 6, and a third gear 7 are installed inside the housing 1. The output shaft of the motor 3 is fixedly connected to the first worm gear 4. The second gear 6 is fixed on the top of the third gear 7. The first gear 5 meshes with the outside of the second gear 6. The first gear 5 meshes with the first worm gear 4. The rotating frame 12 is fixed on the top of the second gear 6. A second worm gear 8 is installed on one side of the base 11. The second worm gear 8 meshes with the outside of the third gear 7. A knob 9 is fixed at both ends of the second worm gear 8 after it passes through the base 11.

[0015] like Figure 2 As shown, a first fixed plate 10 is fixed inside the rotating frame 12, the motor 3 is fixed on the first fixed plate 10, the end of the first worm gear 4 away from the motor 3 has a first rotating shaft 20, one end of the first fixed plate 10 has a bearing seat 101, the first rotating shaft 20 is inserted into the bearing seat 101 and rotates with the bearing seat 101.

[0016] like Figure 3 As shown, a second fixing plate 30 is fixed inside the rotating frame 12, and a second rotating shaft 40 extending vertically is fixed on the second fixing plate 30. The first gear 5 is sleeved on the second rotating shaft 40. A retaining ring 50 is fixed at the bottom of the second rotating shaft 40, which blocks the bottom of the first gear 5 to prevent the first gear 5 from falling off.

[0017] During electric adjustment, motor 3 drives the first worm gear 4 to rotate, the first worm gear 4 drives the first gear 5 to rotate, the first gear 5 drives the second gear 6 to rotate, and the second gear 6 drives the rotating frame 12 to rotate. During manual adjustment, knob 9 drives the second worm gear 8 to rotate, the second worm gear 8 drives the third gear 7 to rotate, the third gear 7 drives the second gear 6 to rotate, and the second gear 6 drives the rotating frame 12 to rotate.
