Description

Technical Field

[0001] The utility model relates to a laser spirit level bracket, belonging to the field of surveying and mapping tools. Background Art

[0002] A spirit level is a measuring instrument that uses the principle of liquid level horizontality, directly displays angular displacement with a spirit bubble, and measures the deviation degree of the measured surface from the horizontal position, vertical position, and inclined position. It is widely used in the construction industry. With the progress of technology, lasers have been added to spirit levels for marking and measuring at longer distances and larger ranges.

[0003] However, the existing laser spirit levels are placed and fixed by placing a tripod at the bottom. This fixing method cannot achieve the free translation and rotation of the laser spirit level. It is necessary to move the bracket together. After rotation, it is necessary to level again, which affects the measurement accuracy. Moreover, when the laser spirit level is placed independently, it is easy to be knocked down by the human body or tools, causing damage to the spirit level. Summary of the Invention

Specific Embodiments

[0022] The principles and features of the present utility model will be described below with reference to the drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0023] As Figure 1-2As shown in the figure, the laser level support includes a support base 01, a support rod 02, and a fixing base 03;

[0024] The support rod 02 includes a rod base 21. The rod base 21 is snap - connected to the fixing base 03 and can rotate axially along the fixing base 03. The upper end face of the fixing base 03 has a positioning hole 31. A screw passes through the positioning hole 31 to fix the position of the rod base 21. One end of the rod base 21 away from the support base 01 extends outward to form two movable rods 22. The ends of the movable rods 22 are integrally connected and form a stabilizing rod 23 at the connection. The middle part of the stabilizing rod 23 has a first threaded hole;

[0025] The support base 01 includes an upper seat 11 and a lower seat 12 which are fixedly connected. A channel for the movable rod 22 to slide is formed between the upper seat 11 and the lower seat 12. A bolt is fixedly connected inside the channel. The bolt is thread - connected with a screw rod. One end of the screw rod away from the bolt passes through the channel and the first threaded hole in sequence and is integrally provided with a first knob 24;

[0026] A rotating mechanism is arranged on the lower end face of the support base 01. The lower end face of the rotating mechanism has a second threaded hole for installing a laser level.

[0027] In another embodiment of the present utility model, the rotating mechanism includes a rotating plate 13. The center of the upper end face of the rotating plate 13 is connected to the lower end face of the lower seat 12 and can rotate axially along the connection. Gear teeth 14 are circumferentially distributed on the upper end face of the rotating plate 13 around the center point. A rotating shaft 15 is arranged on the side wall of the lower seat 12. One end of the rotating shaft 15 has a crown gear meshing with the gear teeth 14, and the other end has a second knob.

[0028] In another embodiment of the present utility model, moving grooves are respectively formed on the upper end face and the lower end face of the rod base 21. A rotating shaft 25 is movably arranged in the middle of the rod base 21. A third threaded hole is penetrated through the middle of the rotating shaft 25. A screw passes through the positioning hole 31, the moving groove on the upper end face, the third threaded hole, and the moving groove on the lower end face in sequence and is thread - connected with the third threaded hole.

[0029] In another embodiment of the present utility model, one end of the screw away from the positioning hole 31 has a third knob.

[0030] In another embodiment of the present utility model, as Figure 3 shown, it further includes a fixing plate 04. The fixing plate 04 is detachably connected to the end of the fixing base 03 away from the support rod 02. The fixing plate 04 has a mounting hole 41.

[0031] The following describes the usage method of the laser level support of the present utility model in combination with the above structure:

[0032] Fixing method: The fixing base 03 can be directly pasted on the wall surface or the surface of the device, or one or more fixing plates 04 can be pasted on the wall surface or the surface of the device or fixed through the mounting holes 41, and the fixing base 03 and the fixing plate 04 are connected in a clamping manner. When there are multiple fixing plates 04, the bracket can be freely switched among the multiple fixing plates 04 to adapt to measurements in different scenarios.

[0033] Horizontal rotation: Rotate the second knob, the rotating shaft 15 drives the crown gear to rotate, and drives the rotating plate 13 to rotate through the gear teeth 14. The laser level set on the lower end surface of the rotating plate 13 can thus achieve horizontal rotation.

[0034] Horizontal translation: Rotate the first knob 24 to drive the screw rod to rotate. The bolt threadedly connected to the screw rod moves on the screw rod accordingly, and then drives the support base 01 to move on the movable rod 22. The laser level set on the lower seat 12 can thus achieve horizontal translation.

[0035] Angle adjustment: Rotate the screw, the position of the screw on the third threaded hole changes. Then, affected by gravity, the support rod 02 clamped on the fixing base 03 performs axial movement. At this time, the rotating shaft 25 rotates, the angle between the screw and the rod seat 21 changes, and the screw moves in the moving groove to realize the angle change of the support rod 02, and thus realize the angle adjustment of the laser level in the vertical direction.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
