Detailed Implementation

[0016] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1-3 This embodiment includes a housing 200 and a base 300. The laser assembly is installed inside the housing 200 and has multiple laser heads that emit linear light outwards from the housing 200. The base 300 is movably mounted on a fixed object, typically a wall or beam. The housing 200 has a hollow structure and is used to house the laser assembly; the housing 200 is rotatably mounted on the base 300.

[0018] In this embodiment, the base 300 is provided with a mounting body 301. The mounting body 301 is provided with a fixing part 304 and a protruding part 302 provided on the fixing part 304. The protruding part 302 is a cylindrical structure fixed in the middle of the mounting body 301. The mounting body 301 is also provided with an annular groove surrounding the protruding part 302. The fixing part 304 is an annular structure and is located in the annular groove.

[0019] In this embodiment, the housing 200 is provided with a mounting portion movably mounted on the protrusion 302. The bottom of the housing 200 is provided with a mating hole to accommodate the rotation of the protrusion 302 therein. The fixing portion 304 has a ring-shaped structure. Multiple mounting portions 202, such as three, are provided and are adsorbed onto the fixing portion 304. The mounting portion 202 and the fixing portion 304 are a magnet and a magnetically conductive metal, respectively. A friction block 204 is provided on the housing 200, and the friction block 204 contacts the surface of the base 300. The friction between them, without external force, can restrict the relative movement of the two.

[0020] In this embodiment, the housing 200, on which the laser component is mounted, is rotatably connected to the base 300. On one hand, under external force (such as manual rotation), the housing 200 can rotate freely relative to the base 300. On the other hand, a friction block 204 is provided between the housing 200 and the base 300, and the resulting friction ensures that the housing 200 remains fixed relative to the base 300 after the external force is removed. This embodiment achieves both rotational adjustment and wall mounting of the laser component.

[0021] like Figure 4-8 As shown, the laser assembly 100 of this embodiment includes a fixed base 102 and a laser head 104. The fixed base 102 is provided with a cylindrical mounting hole 106. The laser head 104 is a cylindrical structure, one end of which is used to emit a laser line. The laser head 104 is installed in the mounting hole 106 and there is an movable gap between the laser head 104 and the mounting hole 106.

[0022] In this embodiment, three mounting holes 106 are arranged on the fixed seat 102. The three mounting holes 106 form a structure like the Chinese character "pin". The axes of two of the mounting holes 106 are on the same straight line, and the axis of the other mounting hole 106 is perpendicular to this straight line and is located between the above two mounting holes 106. A laser head 104 is provided in each mounting hole 106. Its function is to emit linear laser in three mutually perpendicular directions. In this embodiment, an annular boss 108 concentric with it is provided on the outer cylindrical wall of the laser head 104. The circumferential surface of the boss 108 contacts the inner wall of the bottom of the mounting hole 106; the fixed seat 102 is provided with a first adjustment hole 110. The first adjustment hole 110 is communicated with the mounting hole 106 and penetrates upward through the upper surface of the fixed seat 102. The first imaginary axis of the first adjustment hole 110 eccentrically passes through the boss 108. A first adjustment rod 111 that can move along its axial direction and can extend downward at least partially out of the first adjustment hole 110 is also provided in the first adjustment hole 110. In this embodiment, the fixed seat 102 is provided with a second adjustment hole 112. The second adjustment hole 112 is communicated with the mounting hole 106 and penetrates upward to the upper surface of the fixed seat 102; a convex structure 114 is provided at the central position of the bottom of the inner wall of the mounting hole 106. The convex structure 114 contacts the outer wall of the laser head 104; a second adjustment rod 113 that can move along its axial direction and can extend downward at least partially out of the second adjustment hole 112 is also provided in the second adjustment hole 112. When the second adjustment rod 113 contacts the laser head 104 and continues to move downward, it can push the laser head 104 to rotate along the second imaginary axis. The second imaginary axis passes through the center of the laser head 104 and the convex structure 114 along the radial direction of the laser head 104. A flat concave 120 is also provided on the boss 108. When the first adjustment rod 111 contacts the boss 108, its free end abuts against the flat concave 120. In addition, in the embodiment, a third adjustment hole 116 that penetrates its lower surface and is communicated with the mounting hole 106 is provided at the bottom of the fixed seat 102. The convex structure 114 is a third adjustment rod 118 which is a rod-shaped structure installed in the third adjustment hole 116 and can move along the axial direction of the third adjustment hole 116. The top of the third adjustment rod 118 can at least partially extend into the mounting hole 106. In this embodiment, the rotation of the laser head 104 around the axis direction is realized by the first adjustment rod 111. Specifically, rotate the first adjustment rod on one side 111 to make it move along its axial direction. The free end of the first adjustment rod 111 abuts against the flat concave 120 of the boss 108 and pushes the laser head 104 to rotate around its axis, realizing the rotation of the laser head 104. Of course, the first adjustment rod 111 on the other side can also be adjusted, and its rotation direction is exactly opposite.The left-right swing of the laser head 104 is achieved by the second adjusting rod 113. Specifically, rotating one side of the second adjusting rod 113 causes it to move along its axial direction. The free end of the second adjusting rod 113 abuts against the laser head 104. Continuing to move, the force of the second adjusting rod 113 causes the laser head 104 to rotate around the protruding structure 114 at the bottom of the inner wall of the mounting hole 106. The axis of rotation passes radially through the center of the laser head 104 and the protruding structure 114, thereby causing the laser head 104 to swing upwards. In this embodiment, two first adjusting holes 110 are provided, symmetrically arranged along an imaginary plane passing through the axis of the laser head 104. The shortest line connecting the two first adjusting holes 110 is perpendicular to this imaginary plane. Each first adjusting hole 110 contains a first adjusting rod 111. Two second adjusting holes 112 are also provided, symmetrically arranged along an imaginary plane. The shortest line connecting the two second adjusting holes 112 is perpendicular to the imaginary plane. Each second adjusting hole 112 contains a second adjusting rod 113. Two first adjusting rods 111 and two second adjusting rods 113 are provided, which can adjust the rotation or swing of the laser head 104 in both clockwise and counterclockwise directions.

[0023] In this embodiment, the first adjusting hole 110, the second adjusting hole 112, and the third adjusting hole 116 are provided with internal threads, and the first adjusting rod 111, the second adjusting rod 113, and the third adjusting rod 118 are provided with external threads that respectively engage with the threads of the first adjusting hole 110, the second adjusting hole 112, and the third adjusting hole 116. The threaded connection method ensures a defined stroke for the first adjusting rod 111, the second adjusting rod 113, and the third adjusting rod 118, while also ensuring fixation after adjustment.

[0024] Example 2 In this embodiment, a mounting pin 400 is also provided. The mounting pin 400 includes a needle-like insertion part and a head that is disposed at one end of the insertion part and extends radially outward. The mounting body 301 is provided with at least two mounting holes 303, which allow the insertion part to pass through and restrict the head from passing through. The mounting body 301 is also provided with a mounting groove for the head of the mounting pin 400 to engage.

[0025] In this embodiment, mounting nails 400 are provided to fix the mounting body 301 and the base 300 to the wall. The mounting nails 400 can be removed during disassembly. In addition, the mounting body 301 is also provided with a mounting groove for storing the mounting nails 400 when not in use.

[0026] Example 3 The difference between this embodiment and Embodiment 1 is that the protruding structure 114 is a protruding structure fixed to the bottom of the inner wall of the mounting hole 106.

[0027] Example 4 In this embodiment, three mounting holes 106 are arranged on the fixed seat 102. The three mounting holes 106 form a "pin" - shaped structure. The axes of two of the mounting holes 106 are on the same straight line, and the axis of the other mounting hole 106 is perpendicular to them and is located between the above - mentioned two mounting holes 106. A laser head 104 is arranged in each mounting hole 106. In this embodiment, by setting three laser heads 104, and the laser heads 104 emit three light rays in a "pin" - shaped manner, it meets the needs of daily marking lines.
