[0002] Laser line projectors are widely used in many fields, such as building construction, interior decoration, and engineering surveying, to provide horizontal, vertical, or inclined laser lines to assist workers in precise measurement, positioning, and calibration. To ensure that the laser line projector can accurately project the required lines, its mounting bracket needs to be height-adjustable and capable of fine-tuning its position.

[0003] Traditional laser line projector brackets often suffer from low adjustment precision and inconvenient operation in terms of height adjustment. For example, some simple brackets may only allow for manual plugging and unplugging or limited adjustment levels to change the height, making it difficult to achieve continuous and precise height adjustment and meet the precise height requirements of laser line projectors in different working scenarios.

[0004] Furthermore, fine-tuning the position of the laser line projector is crucial in practical use. Due to the complexity of construction sites or working environments, frequent adjustments to the horizontal position and projection angle of the laser line projector may be necessary to ensure the accuracy and applicability of the markings. However, existing brackets lack sufficient fine-tuning capabilities, failing to provide convenient and precise lateral movement and angle rotation adjustments. This inconveniences workers and impacts work efficiency and measurement accuracy. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a new type of screw lifting support structure.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 1-3 A novel screw-lifting bracket structure includes a base 1, a back plate 2 fixedly mounted on the base 1, and a rubber pad 3 fixedly mounted on the outer side of the back plate 2 by screws. A magnet 4 is fixedly mounted on the rubber pad 3 by screws. The screw-lifting bracket can be used with a tripod or a ferrous object surface for adsorption, enabling micro-motion vertical adjustment and rapid alignment. A movable slide 5 is provided above the base 1, and the movable slide 5 is vertically slidably connected to the back plate 2. A screw-lifting positioning component 6 for adjusting the height of the movable slide 5 is provided on the base 1. A mounting block 7 is provided above the movable slide 5, and mounting bolts 8 are fixedly connected to the mounting block 7 for mounting a laser line projector.

[0030] The lead screw lifting and positioning assembly 6 includes a gear bracket 61 fixedly mounted on the base 1. A rotating shaft 62 is rotatably connected to the gear bracket 61. A first helical gear 63 is inserted through the rotating shaft 62 and fixedly connected thereto. A second helical gear 64 meshes with the outer side of the first helical gear 63. An adjusting lead screw 65 is inserted through the second helical gear 64 and fixedly connected thereto. Lead screw fixing blocks 66 are rotatably connected to the top and bottom ends of the adjusting lead screw 65. The two lead screw fixing blocks 66 are fixedly connected to the back plate 2 respectively. The adjusting lead screw 65 is inserted into the movable slide 5 and threadedly connected to the movable slide 5. A handwheel 67 is fixedly connected to the rotating shaft 62 on the outer side of the gear bracket 61. By rotating the handwheel 67, the rotating shaft 62 is rotated, and through the transmission of the first helical gear 63 and the second helical gear 64, the adjusting lead screw 65 is rotated, thereby driving the movable slide 5 to rise and fall.

[0031] The back plate 2 has an integrally formed vertical limiting protrusion 21 on its surface, and the movable slide 5 has a limiting hole 51 that matches the limiting protrusion 21. The movable slide 5 is slidably connected to the back plate 2 through the vertical limiting protrusion 21 and the limiting hole 51. The cooperation between the limiting protrusion 21 and the limiting hole 51 ensures the stability of the movable slide 5 in vertical sliding on the back plate 2.

[0032] Example 2

[0033] Please see Figure 1 , 45. This embodiment is a further improvement on the basis of embodiment 1. Compared with embodiment 1, the bottom of the mounting block 7 is provided with a fine adjustment mechanism 9, which includes a horizontal movement component 91 and an angle rotation adjustment component 92.

[0034] The lateral movement assembly 91 includes a fine-tuning lower plate 911, which is slidably connected to the top of the movable slide table 5. A movable opening 912 is provided in the center of the top of the fine-tuning lower plate 911, and a fine-tuning fixing seat 913 is disposed within the movable opening 912. The bottom of the fine-tuning fixing seat 913 is fixedly connected to the top of the movable slide table 5 by screws. A fine-tuning screw 914 is threaded onto the fine-tuning fixing seat 913. A middle frame 915 is fixedly connected to the top of the fine-tuning lower plate 911. Both ends of the fine-tuning screw 914 pass through and extend to the outer sides of the middle frame 915. By rotating the fine-tuning screw 914, the fine-tuning lower plate 911 can move laterally left and right on the movable slide table 5, thereby fine-tuning the lateral position of the middle frame 915 and the mounting block 7.

[0035] The angle rotation adjustment assembly 92 includes a worm gear 921 rotatably mounted within a middle frame 915. A worm 922 meshes with the outer side of the worm gear 921 and is rotatably connected to the middle frame 915. One end of the worm 922 extends to the outside of the middle frame 915. A turntable 923 is fixedly connected to the top of the worm gear 921, and a mounting block 7 is fixedly mounted on the top of the turntable 923. Rotating the worm 922 drives the worm gear 921 to rotate, thereby achieving angle rotation adjustment of the turntable 923 and the mounting block 7. Knobs 10 are fixedly connected to both ends of the fine-tuning screw 914 and the end of the worm 922 located outside the middle frame 915, facilitating the operator's rotation of the fine-tuning screw 914 and the worm 922.

[0036] Working principle:

[0037] Height Adjustment: When the height of the movable slide 5 needs to be adjusted, the operator rotates the handwheel 67. The handwheel 67 drives the rotating shaft 62 to rotate, and the first helical gear 63 on the rotating shaft 62 rotates accordingly. The first helical gear 63 meshes with the second helical gear 64, thereby driving the second helical gear 64 to rotate. The second helical gear 64 drives the adjusting screw 65 to rotate. Since the adjusting screw 65 is threadedly connected to the movable slide 5, and the movable slide 5 is slidably connected to the back plate 2 through the vertical limiting protrusion 21 and the limiting hole 51, when the adjusting screw 65 is rotated, the movable slide 5 will move vertically along the back plate 2 to achieve height adjustment.

[0038] Lateral fine-tuning: When it is necessary to make lateral fine-tuning of the mounting block 7, the operator rotates the knob 10 on the fine-tuning screw 914, causing the fine-tuning screw 914 to rotate on the fine-tuning fixing seat 913. Since the fine-tuning lower plate 911 is threadedly engaged with the fine-tuning screw 914 and is slidably connected to the top of the moving slide table 5, when the fine-tuning screw 914 rotates, the fine-tuning lower plate 911 will move laterally on the moving slide table 5, thereby driving the middle frame 915 and the mounting block 7 to move laterally, thus achieving lateral fine-tuning of the position.

[0039] Angle adjustment: When the angle of the mounting block 7 needs to be adjusted, the operator can rotate the knob 10 at the end of the worm 922. The worm 922 rotates and drives the worm wheel 921 that meshes with it to rotate. The turntable 923 on the top of the worm wheel 921 rotates accordingly. Since the mounting block 7 is fixedly installed on the top of the turntable 923, the mounting block 7 will rotate together with the turntable 923 to achieve angle adjustment.

[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
