Description

Technical Field

[0001] This utility model belongs to the field of laser adjustment technology, and in particular relates to a laser line adjustment device. Background Technology

[0002] In fields such as building construction, civil engineering, and equipment installation, laser line projectors have become indispensable positioning tools. They use projected horizontal laser lines to mark the required construction height, providing a precise benchmark for construction and are widely used in operations such as wall tile laying, pipeline installation, and door and window positioning.

[0003] In practical use of laser line projectors, it is generally necessary to adjust the height of the projected horizontal laser line. Currently, adjustable brackets are commonly used for this adjustment. However, these brackets are relatively large, especially when using cylindrical single-line or cross-line lasers for laser positioning to facilitate construction. In such cases, smaller adjustment brackets are required, as shown in the attached image. Figure 8 The laser line adjustment mechanism 1 shown includes a connecting plate 11 that can be detachably fixed to various sheet metal or steel structures and other mechanisms on the construction site; a rotating plate 13 rotatably connected to the connecting plate 11 by a positioning bolt 12; a sleeve 14 fixedly connected to the rotating plate 13; and a laser 15 fixedly inserted inside the sleeve 14. Furthermore, an arc-shaped adjustment groove 131 centered on the axis of the positioning bolt 12 is formed on the rotating plate 13. An adjustment bolt 16 is rotatably embedded in the adjustment groove 131 and threadedly connected to the connecting plate 11. When it is necessary to adjust the tilt angle of the laser 15, the adjustment bolt 16 is loosened, the angle of the rotating plate 13 is manually adjusted, and then the adjustment bolt 16 is tightened again.

[0004] The existing laser line adjustment mechanism 1 has the following technical problems: When it is necessary to adjust the height of the laser line emitted by the laser 15, the adjusting bolt 16 needs to be loosened, the rotating plate 13 needs to be rotated, and then the adjusting bolt 16 needs to be tightened, which makes the overall operation relatively complicated; In addition, since the rotating plate 13 needs to be rotated manually, it is difficult to adjust the laser line height precisely; Furthermore, since the connecting plate 11 has been fixed, when it is necessary to project the laser line to another wall or another specified direction, the connecting plate 11 needs to be removed and then installed in the corresponding position, which makes the overall operation relatively troublesome. Utility Model Content

[0005] To address at least one technical problem in the prior art, this application provides a laser line adjustment device that allows for easy and precise adjustment of the laser line height and is convenient to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A laser line adjustment device includes a mounting plate with a top plate and side plates on both sides of the top plate. A screw is rotatably embedded in each of the side plates, and an adjustment block is threaded onto the screw. An adjustment plate is rotatably connected to one side plate, and the two ends of a hinge plate are respectively hinged to the adjustment block and the adjustment plate. A fixing sleeve is fixedly connected to the lower end of the adjustment plate, and a laser is fixedly inserted into the fixing sleeve. Rotating the screw drives the adjustment block to move along the length of the screw, which in turn drives the adjustment plate to rotate via the hinge plate.

[0007] Preferably, the top plate is rotatably connected to the mounting plate via a rotating shaft, and a ball-head plunger is fixedly embedded in the mounting plate; a plurality of limiting holes are provided on the upper end face of the top plate, the limiting holes being arranged on a circumference with the axis of the rotating shaft as the center, and the ball head of the ball-head plunger can be embedded in the corresponding limiting hole and disengage from the corresponding limiting hole.

[0008] Preferably, a rotating knob is fixedly connected to the screw on the outer side of the side plate.

[0009] Preferably, a fixing bolt is threaded into the fixing sleeve, and a fixing knob is fixedly connected to the fixing bolt on the outside of the fixing sleeve. Rotating the fixing knob can cause the fixing bolt to press against the laser to fix the laser inside the fixing sleeve.

[0010] Preferably, the fixing sleeve is fixedly connected to the adjusting plate by fixing sleeve screws.

[0011] Preferably, a limiting plate is fixedly connected to a screw on the outer side of the side plate opposite to the rotating knob.

[0012] Preferably, an annular guide groove is provided on the upper surface of the top plate, and the limiting hole is provided at the bottom of the guide groove.

[0013] Preferably, a vertical plate is fixedly connected to the mounting plate, a fixing plate is fixedly connected to the upper end of the vertical plate, and a connection hole is provided on the fixing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention drives the slider to move along the length of the screw by rotating the drive screw, which in turn drives the hinge plate to rotate the adjustment plate relative to the side plate. This drives the fixed sleeve and the laser to rotate, thereby adjusting the height of the laser emitted by the laser. Furthermore, by rotating the screw, the accuracy and convenience of adjusting the laser line height of the laser can be improved.

[0015] This invention rotatably connects the top plate to the mounting plate via a rotating shaft, allowing the laser to be rotated as needed, thus avoiding the drawback of prior art where the connecting plate or laser must be removed first. Furthermore, by incorporating a ball-head plunger and a limiting hole, the relative position of the top plate and mounting plate is fixed when the ball head of the plunger is embedded in the limiting hole; when the ball head of the plunger disengages from the limiting hole, the top plate can rotate relative to the mounting plate to adjust the horizontal angle of the laser.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example 1

[0027] See appendix Figure 1 , 2 As shown in Figure 5, a laser line adjustment device includes a mounting plate 2, a vertical plate 21 fixedly connected to the mounting plate 2, and a fixing plate 22 fixedly connected to the upper end of the vertical plate 21. The fixing plate 22, the vertical plate 21, and the mounting plate 2 can be integrally formed. A connecting hole 221 is provided on the fixing plate 22. Existing structures such as bolts and nuts can be used to fix the fixing plate 22 to existing sheet metal, steel structures, or other structures through the connecting hole 221. The connection principle is based on existing machine tools and will not be described in detail here. In addition, in order to facilitate the adjustment of the installation position of the fixing plate 22, in this embodiment, the connecting hole 221 is an oblong structure and its length direction is perpendicular to the length direction of the mounting plate 2.

[0028] A top plate 3 is provided on the lower end face of the mounting plate 2. In this embodiment, the top plate 3 can be fixedly connected to the mounting plate 2 by existing bolts. Side plates are provided on both sides of the top plate 3. For ease of description, they are divided into a front side plate 31 closer to the laser line and a rear side plate 32 farther away from the laser line. Screws 4 are rotatably embedded in the front side plate 31 and the rear side plate 32, and the two ends of the screws 4 extend to the outside of the front side plate 31 and the rear side plate 32, respectively.

[0029] A rotary knob 41 is fixedly connected to the screw 4 on the outer side of the rear side plate 32. A limiting plate 42 is fixedly connected to the screw 4 on the outer side of the front side plate 31 opposite to the rotary knob 41. The limiting plate 42 prevents the screw 4 from detaching from the front side plate 31. Rotating the rotary knob 41 drives the screw 4 and the limiting plate 42 to rotate.

[0030] An adjusting block 43 is threaded onto the screw 4 between the front side plate 31 and the rear side plate 32. An adjusting plate 33 is rotatably connected to the rear side plate 32. The two ends of the hinge plate 34 are respectively hinged to the adjusting block 33 and the adjusting plate 33. There are two hinge plates 34, which are respectively located on both sides of the adjusting block 33 and the adjusting plate 33.

[0031] Specifically, the adjusting block screw 431 is rotatably inserted through the hinge plate 34 and threadedly connected to the adjusting block 43. The adjusting block screw 431 is locked within the adjusting block 43, and the hinge plate 34 can rotate relative to the adjusting block 43. Similarly, the adjusting plate screw 331 is rotatably inserted through the hinge plate 34 and threadedly connected to the adjusting plate 33. The adjusting plate screw 331 is locked within the adjusting plate 33, and the hinge plate 34 can rotate relative to the adjusting plate 33.

[0032] A protruding plate 332 is integrally formed at one end of the adjusting plate 33, and a rear side plate groove 321 is formed on the lower end face of the rear side plate 32. The protruding plate 332 is rotatably embedded in the rear side plate groove 321. Specifically, the rear side plate screw 322 is threaded and locked in the rear side plate 32 and passes through the protruding plate 332. The protruding plate 332 can rotate relative to the rear side plate screw 322.

[0033] It should be noted that, in order to avoid the lower end of the front side plate 31 from blocking the adjustment plate 33, in this embodiment, the lower end of the front side plate 31 is higher than the lower end of the rear side plate 32. For example, when the adjustment plate 33 is in a horizontal state, the upper end of the adjustment plate 33 can abut against the lower end of the front side plate 31.

[0034] See Figure 7 As shown, a fixing sleeve 5 is fixedly connected to the lower end of the adjusting plate 33, and an existing laser 15 is fixedly inserted inside the fixing sleeve 5. Specifically, in order to facilitate the fixing sleeve 5 to be fixedly connected to the adjusting plate 33 by fixing sleeve screws 51, a planar notch 52 is provided on the outer circumference of the fixing sleeve 5, and the planar notch 52 can abut against the lower end face of the adjusting plate 33.

[0035] To facilitate the installation and removal of the laser 15 from the fixed sleeve 5, a fixing bolt 53 is threaded inside the fixed sleeve 5, and a fixing knob 54 is fixedly connected to the fixing bolt 53 on the outside of the fixed sleeve 5. Rotating the fixing knob 54 can cause the fixing bolt 53 to press against the laser 15 to fix the laser 15 inside the fixed sleeve 5.

[0036] The working principle and process of this embodiment are as follows: Install the components as described above. The operator can rotate the rotary knob 41 to drive the screw 4 to rotate, which in turn moves the adjusting block 43 and the hinge plate 34 and adjusting plate 33 to rotate, thereby adjusting the horizontal angle of the fixing sleeve 5 and the laser 15 to adjust the height of the horizontal laser line emitted by the laser 15. Example 2

[0037] See appendix Figure 3 , 4 As shown in Figure 6, this embodiment is a further improvement on the basis of embodiment 1. The difference between this embodiment and embodiment 1 is that the top plate 3 and the mounting plate 2 are rotatably connected and the relative position between them is limited by the limiting component.

[0038] The top plate 3 is rotatably connected to the mounting plate 2 via a rotating shaft 6. An upper limit cap 61 is fixedly connected to the rotating shaft 6 above the mounting plate 2, and a lower limit cap 62 is fixedly connected to the rotating shaft 6 below the top plate 3. The rotating shaft 6, the upper limit cap 61, and the lower limit cap 62 can be integrally formed, such as by riveting the upper limit cap 61 and the lower limit cap 62 to the rotating shaft 6. Of course, the upper limit cap 61 and the lower limit cap 62 can also be fixedly connected to the rotating shaft 6 in other ways, allowing the top plate 3 to rotate relative to the mounting plate 2.

[0039] To limit the relative rotation angle between the top plate 3 and the mounting plate 2, in this embodiment, the limiting component includes a ball-head plunger 7 vertically fixedly embedded in the mounting plate 2. The ball-head plunger 7 has a prior art structure, comprising a plunger housing 71, a spring 72 passing through the plunger housing 71, and a ball head 73 located at one end of the spring 72 near the outlet of the plunger housing 71. The plunger housing 71 is threaded into the mounting plate 2, and the ball head 73 abuts against the top plate 3 under the elastic force of the spring 72. Multiple ball-head plungers 7 can be provided; in this embodiment, two are provided. The elastic force of the spring 72 provides a certain degree of damping when the top plate 3 rotates relative to the mounting plate 2, thus limiting the rotation of the top plate 2 to a certain extent.

[0040] Furthermore, multiple limiting holes 35 are evenly distributed on the upper surface of the top plate 3. The limiting holes 35 are arranged on a circle with the axis of the rotating shaft 6 as the center. In this embodiment, four limiting holes 35 are evenly distributed, but the number can be adjusted according to the rotation angle requirements of the top plate 3. The ball head of the ball plunger 7 can be embedded in the corresponding limiting hole 35 and disengaged from the corresponding limiting hole 35.

[0041] Thus, in the initial state, the ball heads 73 of the two ball plungers 7 are embedded in the corresponding two limiting holes 35 under the elastic force of the spring 72, thereby fixing and limiting the top plate 3; when the top plate 3 is rotated, the ball heads 73 can compress the spring 72 and disengage from the corresponding limiting holes 35. After rotating a set angle, the ball heads 73 are re-embedded in the corresponding limiting holes 35.

[0042] Furthermore, in order to facilitate the guidance of the top plate 3 when rotating the top plate 3, an annular guide groove 36 is provided on the upper end face of the top plate 3, and a limiting hole 35 is provided at the bottom of the guide groove 36, that is, the ball head 73 slides in the guide groove 36.

[0043] The working principle and process of this embodiment are as follows: Install the components as described above. When adjusting the height of the horizontal laser line emitted by the laser 15, the operator can rotate the rotary knob 41 to drive the screw 4 to rotate, which in turn moves the adjusting block 43 and rotates the hinge plate 34 and the adjusting plate 33, thereby adjusting the horizontal angle of the fixing sleeve 5 and the laser 15 to adjust the height of the horizontal laser line emitted by the laser 15. When adjusting the horizontal angle of the laser 5, rotate the top plate 3 to the specified angle and the ball head 73 is embedded in the corresponding limiting hole 35. During this process, the front side plate 31, the rear side plate 32, the screw 4, the hinge plate 34, the fixing sleeve 5, and the laser 15 rotate synchronously with the top plate 3.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
