Description

Technical Field

[0001] This utility model relates to the field of laser level technology, specifically a level holder. Background Technology

[0002] Laser levels are used in many fields such as building layout, interior decoration, furniture installation, and pipeline laying. Laser levels can be used on the ground or a table, or with a level holder. The holder typically consists of a base, a main frame, and a lifting frame. The level is fixed to the lifting frame, and the holder attaches to metal objects using multiple magnets on its back. Since the back is flat, it can only achieve good adhesion and adhesion to flat metal surfaces, which limits its application. In actual working environments, besides flat metal plates, there are also many metal pipes. Existing level holders cannot effectively adhere to metal pipes because there are insufficient adhesion points, and even when they do, they tend to wobble. This greatly limits the scope of use of level holders. Utility Model Content

[0003] In view of the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a level holder.

[0004] The technical solution of this utility model is: a level bracket, including a base, a main frame vertically fixed to the rear end of the base, a lifting frame installed at the front end of the main frame, a knob installed on both the left and right sides of the lifting frame, a gear connected between the two knobs, a rack plate fixed to the front end of the main frame, the rack plate having a rack extending vertically at the front end, the rack meshing with the gear, and two rotatable movable plates installed at the rear end of the main frame, with multiple magnets fixed to the rear end of each of the two movable plates.

[0005] Furthermore, the rack plate has vertically extending grooves on both the left and right sides, and the lifting frame has sliders on both the left and right sides of the rear end. The sliders are engaged with the grooves and slide vertically with the grooves.

[0006] Furthermore, the lifting frame has elastic grippers composed of two arc-shaped clamps on both the left and right sides. The inner sides of the two knobs have left and right extending fixing rods, which are fixedly connected to the gears. The elastic grippers have through holes that extend left and right and allow the fixing rods to pass through. A locking ring is installed at both ends of the lifting frame. The locking ring rotates and fits around the elastic grippers. The locking ring is used to drive the elastic grippers to clamp the fixing rods.

[0007] Furthermore, the lifting frame has two arc-shaped grooves on both the left and right sides. The arc-shaped grooves are located on the outer side of the arc-shaped clamping plate. One end of the arc-shaped groove has an extended first limiting groove. The inner side of the locking ring has two locking blocks. The first limiting groove is for the locking blocks to be inserted. The inner side of the locking blocks has a protruding locking strip. The outer side of the end of the arc-shaped clamping plate has a second limiting groove for the locking strip to be inserted. There is a gap between the two arc-shaped clamping plates. When the locking block rotates into the arc-shaped groove, the locking block presses the arc-shaped clamping plate inward, so that the arc-shaped clamping plate clamps the fixing rod.

[0008] Furthermore, a lever protrudes from the outer side of the locking ring.

[0009] Furthermore, the two movable plates are distributed to the left and right. One movable plate has a first arc-shaped toothed plate and a first rotating shaft at its left and right ends, respectively. The other movable plate has a second rotating shaft and a second arc-shaped toothed plate at its left and right ends, respectively. The first arc-shaped toothed plate meshes with the second arc-shaped toothed plate. There is a movable groove at both the left and right ends of the main frame. The first rotating shaft and the second rotating shaft are respectively inserted into a movable groove and rotate in cooperation with the movable groove.

[0010] The advantages of using the level bracket provided by this utility model are: two rotatable movable plates are installed at the rear end of the main frame, and multiple magnets are fixed at the rear end of each movable plate, which can attract the level bracket to a metal object. Because the angle between the two movable plates is adjustable, it can not only attract flat metal tubes, but also stably attract circular metal tubes. Attached Figure Description

Detailed Implementation

[0019] 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:

[0020] like Figure 1 — Figure 7 As shown, a level holder includes a base 1, a main frame 2 vertically fixed to the rear end of the base 1, a lifting frame 3 mounted to the front end of the main frame 2, a knob 4 mounted on each of the left and right sides of the lifting frame 3, and a gear 5 connecting the two knobs 4. A rack plate 6 is fixed to the front end of the main frame 2, and the front end of the rack plate 6 has vertically extending racks 61 that mesh with the gear 5. Two rotatable movable plates 7 are mounted to the rear end of the main frame 2, and multiple magnets 8 are fixed to the rear ends of both movable plates 7. Rotating the knobs 4 allows the lifting frame 3 to move up and down.

[0021] like Figure 2 As shown, in order to improve the stability of the lifting frame 3 when it moves up and down, the left and right sides of the rack plate 6 have vertically extending grooves 62, and the left and right sides of the rear end of the lifting frame 3 have sliders 31. The sliders 31 are inserted into the grooves 62 and slide up and down with the grooves 62.

[0022] like Figure 3As shown, the lifting frame 3 has elastic grippers 32 composed of two arc-shaped clamping plates 321 on both the left and right sides. The inner sides of the two knobs 4 have left and right extending fixing rods 41, which are fixedly connected to the gears 5. The elastic grippers 32 have through holes 322 that extend left and right and allow the fixing rods 41 to pass through. A locking ring 9 is installed at both the left and right ends of the lifting frame 3. The locking ring 9 is rotated and sleeved on the outside of the elastic grippers 32. The knobs 4 are against the outside of the locking rings 9. The fixing rods 41 of the knobs 4 pass through the locking rings 9. The locking rings 9 are used to drive the elastic grippers 32 to clamp the fixing rods 41. The lifting frame 3 has two arc-shaped grooves 33 on both its left and right sides. The arc-shaped grooves 33 are located outside the arc-shaped clamping plate 321. One end of the arc-shaped groove 33 has an extended first limiting groove 331. The inner side of the locking ring 9 has two locking blocks 91. The first limiting groove 331 is for the locking blocks 91 to be engaged. The inner side of the locking blocks 91 has a protruding locking strip 911. The outer side of the end of the arc-shaped clamping plate 321 has a second limiting groove 3211 for the locking strip 911 to be engaged. There is a gap between the two arc-shaped clamping plates 321. When the locking blocks 91 rotate into the arc-shaped groove 33, the locking blocks 91 press the arc-shaped clamping plate 321 inward, so that the arc-shaped clamping plate 321 clamps the fixing rod 41. At this time, the locking strip 911 is engaged in the second limiting groove 3211. The outer side of the locking ring 9 has a protruding lever 92. When in use, the locking ring 9 can be rotated by pinching the lever 92. To move the lifting frame 3, rotate the locking ring 9, and rotate the locking block 91 of the locking ring 9 into the first limit groove 331. The elastic gripper 32 will then release the fixing rod 41. The elastic gripper 32 and the locking ring 9 are both plastic parts with a certain degree of elasticity. The locking block 91 and the arc-shaped clamping plate 321 can both deform during operation.

[0023] like Figure 6 , Figure 7 As shown, two movable plates 7 are distributed left and right. One movable plate 7 has a first arc-shaped toothed plate 71 and a first rotating shaft 72 at its left and right ends, respectively. The other movable plate 7 has a second rotating shaft 73 and a second arc-shaped toothed plate 74 at its left and right ends, respectively. The first arc-shaped toothed plate 71 and the second arc-shaped toothed plate 74 mesh with each other. The main frame 2 has a movable groove 21 at both its left and right ends. The first rotating shaft 72 and the second rotating shaft 73 are respectively inserted into a movable groove 21 and rotate in cooperation with the movable groove 21. Figure 5 As shown, the rear ends of the two movable plates 7 are on the same horizontal plane. This is for objects that need to be attracted to a flat surface, such as when magnet 8 is to be attracted to a flat metal plate. Figure 4 As shown, an obtuse angle is formed between the two movable plates 7. This is for cylindrical objects to be adsorbed, thus providing more adsorption points. For example, when adsorbing a metal tube, both movable plates 7 have adsorption points, and the metal tube can also be held between the two movable plates 7. To... Figure 5 The activity board 7 in the current state is switched to Figure 4In this state, simply press the movable plate 7 forward, or press it against the cylindrical metal tube; this will also achieve the desired effect. Figure 4 The activity board 7 in the current state is switched to Figure 5 In this state, simply align magnet 8 with the flat surface of the metal plate, and magnet 8 will be attracted to the flat surface, thus switching to the desired state. Figure 5 It's in a good state.

[0024] The present invention provides a level holder with two rotatable movable plates 7 installed at the rear end of the main frame 2. Each movable plate 7 has multiple magnets 8 fixed at its rear end, which can attract the level holder to a metal object. Because the angle between the two movable plates 7 is adjustable, it can not only attract flat metal tubes, but also stably attract circular metal tubes.

[0025] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
