Description
Technical Field
[0001] The utility model specifically relates to the technical field of level instrument auxiliary devices, in particular to an auxiliary device which facilitates the horizontal sliding of a laser level instrument. Background Art
[0002] In construction or decoration, it is often necessary to rely on tools to obtain horizontal or vertical lines. A laser level is an electronic instrument that can accurately project horizontal and vertical laser beams on a spatial plane, providing convenience for subsequent construction. Usually, laser levels are divided into 2-line, 3-line, and 5-line laser levels according to their models. Among them, a 2-line laser level refers to a laser level that can project two mutually perpendicular laser lines in both the horizontal and vertical directions. The 3-line and 5-line laser levels increase the number of laser lines projected in the horizontal or vertical direction on the basis of the 2-line laser level, and in principle they are no different from the 2-line laser level.
[0003] Although the existing level can realize multi-angle laser projection to achieve 360-degree laser marking without blind spots, there are many concrete columns in the construction industry, which will block the laser line at a certain place, resulting in part of the laser line not being able to be projected normally to the position that needs to be measured. Therefore, the staff is required to mark the height of the existing laser line and then move the laser level to re-mark the line.
[0004] However, due to the unevenness of the construction site, the levelness of the spirit level changes after being moved; this requires adjusting the laser line to the position of the previously marked point before continuing the laser line measurement, which is a very troublesome operation. Utility Model Content
[0005] The purpose of the utility model is to provide an auxiliary device that facilitates the horizontal sliding of a laser level. After the first line is drawn, the measuring point is marked. If there is a concrete column blocking it, the laser level is slid so that the blocked part can be hit by the laser line and then directly marked. This horizontal sliding auxiliary device is relatively stable, and the horizontality of the level will not change during the sliding process, so it is extremely convenient to use, so as to solve the technical problems raised in the above-mentioned background technology.

[0030] By adopting the above technical solution, when in use, first unfold a slide bar assembly 1 and a second slide bar assembly 2, and lock the first slide bar assembly 1, the second slide bar assembly 2 and the connecting piece 3 by means of the locking bolt 7, then install the laser level on the level mounting seat 6, and the laser level shoots out a laser line. After the first line is drawn, the measuring point is marked. If there is a concrete column blocking it, move the slide seat 51 along the first slide bar assembly 1 and the second slide bar assembly 2, so that the blocked part can be hit by the laser line and then directly marked. This horizontal sliding is relatively smooth, and the level of the level will not change during the sliding process, so it is extremely convenient to use.
[0031] In this embodiment, the first slide bar assembly 1 and the second slide bar assembly 2 each include two parallel metal rods, which are fixed on one side of the end seat 8; and the end surface of the metal rod away from the end seat 8 is arranged in a "D" shape.
[0032] More specifically, the longitudinal section of the connecting member 3 is in a "D" shape, the radius of the connecting member 3 is consistent with the radius of the metal rod, and a plane is provided on the inner side of the connecting member 3, and a locking bolt 7 is installed thereon.
[0033] By adopting the above technical solution, the mutual folding of the first slide bar assembly 1 and the second slide bar assembly 2 can be achieved, and the sliding assembly 5 can be ensured to smoothly pass through the hinge point of the first slide bar assembly 1 and the second slide bar assembly 2, thereby ensuring the smooth movement of the level.
[0034] In this embodiment, the locking bolt 7 is a hexagon socket bolt, and the end of the locking bolt 7 is configured to be in the shape of an optical axis.
[0035] Furthermore, when the connecting piece 3 is fitted into the inner side of the first slide bar assembly 1 and the second slide bar assembly 2, the locking bolt 7 is tightened, and its thread is matched and connected with the connecting piece 3 and the metal rods in the first slide bar assembly 1 and the second slide bar assembly 2, so that the support of the first slide bar assembly 1 and the second slide bar assembly 2 in the unfolded state can be achieved, ensuring that the first slide bar assembly 1 and the second slide bar assembly 2 are in a horizontal or vertical state.
[0036] When the locking bolt 7 is loosened, the end of the locking bolt 7 is movably connected to the metal rods in the first slide bar assembly 1 and the second slide bar assembly 2, so that the first slide bar assembly 1 and the second slide bar assembly 2 can be folded or the angle can be changed.
[0037] In this embodiment, a groove is formed at the bottom of the end seat 8, and two movable legs 4 are movably connected in the groove.
[0038] The contact area between the outrigger 4 and the ground is small, so a suitable stable point can be quickly found on a construction site with uneven ground.
[0039] In this embodiment, the level mounting base 6 is arranged in a C shape, the bottom of the level mounting base 6 is fixed to the slide seat 51, and threaded holes are provided on the side and top surface of the level mounting base 6 for easy installation of the level.
[0040] To be more specific, two guide rods 54 are provided on one side of the slide 51, and the two guide rods 54 are movably connected to the movable plate 53; a spring 55 is also provided between the slide 51 and the movable plate 53; the spring 55 is sleeved on the guide rod 54; a through hole is also opened in the middle position of the movable plate 53, and a plum blossom handle bolt 52 is provided in the through hole, and the plum blossom handle bolt 52 is threadedly connected to the slide 51; auxiliary wheels 56 are mounted on both ends of the movable plate 53; the auxiliary wheels 56 are movably connected to the first slide bar assembly 1 or the second slide bar assembly 2.
[0041] By adopting the above technical solution, when sliding, first loosen the plum blossom handle bolt 52, and under the push of the spring 55, the movable plate 53 slides outward along the guide rod 54, releasing the locking and fixation of the movable plate 53 and the slide seat 51, so that the slide seat 51 can be driven to slide. At this time, the auxiliary wheel 56 slides along the metal rods on the first slide bar assembly 1 and the second slide bar assembly 2; after adjusting to the appropriate position, tighten the plum blossom handle bolt 52.
[0042] As another method of using the utility model:
[0043] Please see attached Figure 4-5After loosening the locking bolt 7, the first slide bar assembly 1 and the second slide bar assembly 2 can be folded at 90 degrees, and then the locking bolt 7 can be locked. At this time, the laser level is installed on the upward surface of the level mounting base 6. In this way, the height of the level can be adjusted, and lines can be drawn at different heights of the building, which is convenient for the staff to mark.
[0044] The working principle of the utility model is: when in use, first unfold a slide bar assembly 1 and a second slide bar assembly 2, and lock the first slide bar assembly 1, the second slide bar assembly 2 and the connecting piece 3 by means of the locking bolt 7, then install the laser level on the level mounting seat 6, and the laser level shoots a laser line. After the first line is shot, the measuring point is marked.

[0045] In this way, the blocked part can be hit by the laser line and then marked directly; this horizontal sliding is relatively smooth, and the level of the spirit level will not change during the sliding process, so it is extremely convenient to use.
