Description

Technical Field

[0001] The utility model belongs to the technical field of laser levels, and in particular relates to a laser module installation structure. Background Art

[0002] With the development of my country's modernization construction, the application of laser level for measurement and construction assistance is becoming more and more widespread. The existing laser level is equipped with a pendulum body, which is connected to the cross axis and achieves balance through the gravity of the pendulum body. A laser module is installed on the pendulum body. Figure 1 As shown, it is the related structure of the existing pendulum body 1 and the laser module 2. The laser module 2 is a stepped cylindrical structure as a whole. An adjustment groove 21 is opened in the middle of the shell of the laser module 2, a cylindrical mounting hole 11 is opened on the pendulum body 1, and an adjustment hole 12 perpendicular to the axis of the mounting hole 11 is opened on the end face of one side of the pendulum body 1. The adjustment hole 12 is connected to the mounting hole 11, and an adjusting screw (not shown in the figure) can be threadedly connected in the adjustment hole 12. The adjusting screw can abut the groove wall of the adjusting groove 21. The left and right and up and down directions of the laser module 2 can be adjusted by adjusting the adjusting screw, thereby realizing the leveling of the laser module 2.

[0003] The above existing structure has the following technical problems when debugging the laser module 2: Since there are many adjustment screws to adjust the laser module 2 left and right and up and down (the "left and right adjustment, up and down adjustment" is based on Figure 1 For example, left-right adjustment in the horizontal direction and up-down adjustment in the longitudinal direction), therefore, the debugging speed of the laser module 2 is slow. In addition, the laser module 2 is subjected to more pressure from the adjusting screws, and the stress release generated is also greater. Utility Model Content

[0004] In order to solve the technical problems existing in the prior art, the present application provides a laser module installation structure which can quickly debug the laser module and has low stress release.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Preferably, the positioning reference hole wall includes two inclined planes 1 and 2 that form a certain angle, and the top screw can extend into the mounting hole and press the shell of the laser module to make the positioning reference surface abut against the inclined planes 1 and 2.

[0014] Preferably, the angle between the first bevel and the second bevel is 60-120°.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model sets a positioning reference hole wall in the mounting hole and sets a positioning reference surface on the shell of the laser module. When the laser module is embedded in the mounting hole, the top screw can press the positioning reference surface of the laser module against the positioning reference hole wall, thereby realizing the surface contact between the shell and the pendulum body, and the laser module can be quickly limited, so as to quickly debug the laser module; further, by setting a bevel three and a bevel four matching the bevel one and the bevel two on the shell of the laser module, the laser module can be quickly further limited, so as to quickly debug the laser module; thus, through the above structure, only one top screw is needed to realize the limitation of the laser module in the left and right directions and the up and down directions, so as to quickly debug the laser module. Compared with the prior art, debugging is more convenient and quick, and since fewer top screws are used, stress release is smaller. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Example 1

[0029] See attached Figure 2 , 3 As shown in Figures 4 and 5, a laser module installation structure includes a pendulum body 1 and a laser module 2, wherein a mounting hole 11 is opened on the pendulum body 1, and a positioning reference hole wall 15 is arranged on the hole wall of the mounting hole 11 along its length direction; the laser module 2 includes a shell 24, and a positioning reference surface 25 matching the positioning reference hole wall 15 is arranged on the outer side surface of the shell 24 along its length direction.

[0030] Specifically, in the present embodiment, the hole wall of the mounting hole 11 includes an arc-shaped portion 111 and a positioning reference hole wall 15 transitionally connected to the arc-shaped portion 111, the positioning reference hole wall 15 includes two inclined planes 112 and 113 forming a certain angle, the inclined planes 112 and 113 are respectively connected to the two ends of the arc-shaped portion 111, that is, the inner cavity of the mounting hole 11 is surrounded by the inner circumference of the arc-shaped portion 111, the inclined planes 112 and 113, wherein the inner diameter of the arc-shaped portion 111 is larger than the outer diameter of the shell 24 of the laser module 2, so as to facilitate the insertion and adjustment of the laser module 2 in the mounting hole 11. The angle between the first bevel 112 and the second bevel 113 can be determined based on the outer diameter of the laser module 2, the specific size of the pendulum 1, and the inner diameter of the mounting hole 11, and is generally set between 60-120°. In the present embodiment, the angle between the first bevel 112 and the second bevel 113 is 90°. In addition, the first bevel 112 and the second bevel 113 can be symmetrically arranged.

[0031] The positioning reference surface 25 of the laser module 2 includes a third bevel 22 and a fourth bevel 23. The third bevel 22 and the fourth bevel 23 are formed by opening a notch on the outer side of the shell 24 of the laser module 2. The angle formed by the third bevel 23 and the fourth bevel 24 is the same as the angle formed by the first bevel 112 and the second bevel 113.

[0032] In addition, in order to quickly achieve the balance of the pendulum body 1 when the laser level is in use, a counterweight hole 14 is opened on the end surface of the pendulum body 1, and a counterweight screw (not shown in the figure) is threadedly connected in the counterweight hole 14. The overall balance of the pendulum body 1 and the laser module 2 can be adjusted by adjusting the depth of the counterweight screw in the counterweight hole 14.

[0033] The housing 24 of the laser module 2 is detachably inserted into the mounting hole 11, and an adjustment hole 12 is provided on one end surface of the pendulum body 1. A top screw 13 is threadedly connected to the adjustment hole 12. The top screw 13 can extend into the mounting hole 11 and press the housing 24 of the laser module 2 to make the positioning reference surface 25 abut against the corresponding positioning reference hole wall 15. That is, the inclined surface 3 22 abuts against the inclined surface 1 112, and the inclined surface 4 23 abuts against the inclined surface 2 113, so as to achieve surface contact between the housing 24 and the pendulum body 1.

[0034] Therefore, when installing the laser module 2, it is only necessary to align the bevel three 22 with the bevel one 112, the bevel four 23 with the bevel two 113, and insert the laser module 2 into the mounting hole 11, and then tighten the top screw 13 to complete the debugging of the laser module 2. At this time, the bevel three 22 is in contact with the bevel one 112, and the bevel four 23 is in contact with the bevel two 113, and then the counterweight screw can be adjusted.

[0035] Therefore, through the above structure, when the top screw 13 presses the laser module 2, the laser module 2 can be completely positioned in the up and down and left and right directions, thereby quickly debugging the laser module. Example 2

[0036] See also Figure 6 As shown, the difference between this embodiment and embodiment 1 is that the specific structures of the positioning reference hole wall 15 and the positioning reference surface 25 are different. In this embodiment, the inner cavity cross-section of the mounting hole 11 is a square structure, and the outer cross-section of the shell 24 is a square structure matching the mounting hole 11; the positioning reference hole wall 15 is a hole wall of the mounting hole 11 opposite to the top screw 13, and the positioning reference surface 25 is a side surface that can abut against the positioning reference hole wall. When installing the laser module 2, it is only necessary to align the positioning reference surface 25 with the positioning reference hole wall 15, and insert the laser module 2 into the mounting hole 11, and then tighten the top screw 13 to complete the debugging of the laser module 2. At this time, the positioning reference surface 25 fits with the positioning reference hole wall 15, and then adjust the counterweight screw. Example 3

[0037] See also Figure 7 As shown, the difference between this embodiment and the first embodiment lies in the specific structures of the positioning reference hole wall 15 and the positioning reference surface 25.

[0038] When installing the laser module 2, it is only necessary to align the positioning reference surface 25 with the positioning reference hole wall 15, and insert the laser module 2 into the mounting hole 11, and then tighten the top screw 13 to complete the debugging of the laser module 2. At this time, the positioning reference surface 25 is in contact with the positioning reference hole wall 15, and then the counterweight screw can be adjusted. Example 4

At this time, the positioning reference surface 25 is in contact with the positioning reference hole wall 15, and then the counterweight screw can be adjusted. Example 5

[0041] See also Fig. 9 As shown, the difference between this embodiment and the first embodiment lies in the specific structures of the positioning reference hole wall 15 and the positioning reference surface 25. In this embodiment, the inner cavity cross section of the mounting hole 11 is a circular structure, that is, the positioning reference hole wall 15 is an arc-shaped inner wall opposite to the top screw 13, and the outer cross section of the housing 24 is a "D"-shaped structure matching the mounting hole 11; the positioning reference hole wall 15 is the hole wall of the mounting hole 11 opposite to the top screw 13, and the positioning reference surface 25 is an arc-shaped surface of the "D"-shaped structure that can abut against the positioning reference hole wall 15, and the top screw 13 abuts against the plane of the "D"-shaped structure so that the positioning reference surface 25 abuts against the positioning reference hole wall 15. At this time, the end of the top screw 13 is a planar structure, and when it abuts against the plane of the "D"-shaped structure, the housing 24 can also be positioned.

[0042] When installing the laser module 2, it is only necessary to align the positioning reference surface 25 with the positioning reference hole wall 15, and insert the laser module 2 into the mounting hole 11, and then tighten the top screw 13 to complete the debugging of the laser module 2.
