Description

Technical Field

[0001] This utility model relates to the field of engineering surveying instrument technology, specifically to a laser line marker with a rotatable laser output window. Background Technology

[0002] Existing 360-degree laser line markers include a housing and a laser module housed within the housing. Two adjacent side walls of the housing are each equipped with a laser output window. Each laser output window includes a glass assembly, specifically a ring-shaped glass element. This ring-shaped glass is composed of four glass panes arranged in a rectangular shape, with adjacent panes bonded together using silicone sealant. During use, the laser emitted by the laser module passes through the ring-shaped glass and is projected onto the work surface, forming a laser line. However, because the adjacent glass panes are bonded together with silicone sealant, the bonded areas block the laser beam, causing four breaks in the laser line on the work surface. This creates blind spots in the work reference, affecting construction efficiency and project quality. Utility Model Content

[0003] The technical problem to be solved by this utility model is a laser marking instrument with a rotatable laser output window. The laser marking instrument of this invention has the characteristics that the laser output window can be manually rotated and adjusted, and will not cause blind spots in the construction benchmark.

[0004] To solve the above-mentioned technical problems, this utility model provides a laser line marker with a rotatable laser output window, including a housing and a laser module disposed within the housing. Laser output windows are respectively provided on two adjacent side walls of the housing. Each laser output window includes a fixed plate and a rotating plate disposed on the side wall. The rotating plate is located outside the fixed plate. The laser output window also includes a glass assembly disposed outside the rotating plate. The glass assembly includes an annular glass. Multiple positioning holes are evenly distributed circumferentially on the rotating plate. Multiple spherical grooves are evenly distributed circumferentially on the outer surface of the fixed plate. The number of spherical grooves is an integer multiple of the number of positioning holes. Ball bearings and springs are sequentially disposed along the axial direction within each positioning hole. The end of each ball bearing away from the spring engages with the corresponding spherical groove, and the end of the spring away from the ball bearing abuts against the glass assembly.

[0005] Furthermore, the glass assembly also includes a first rubber pad disposed on the inner side of the annular glass, a second rubber pad disposed on the outer side of the annular glass, and a glass seat disposed on the outer side of the second rubber pad. The glass seat is fixedly connected to the rotating plate by screws. The first rubber pad and the second rubber pad serve to protect the annular glass.

[0006] Furthermore, the annular glass comprises four glass sheets arranged in a rectangular shape, with adjacent glass sheets bonded together by glass adhesive.

[0007] Furthermore, the number of positioning holes is 4, and the number of spherical grooves is 16; when the glass assembly is manually rotated and adjusted, the glass assembly rotates 22.5 degrees to generate a positioning feedback.

[0008] Furthermore, the housing includes an upper housing and a lower housing that interlock with each other, and the upper housing and the lower housing are fixedly connected by screws. The mounting hole is formed by a first arc-shaped groove and a second arc-shaped groove that interlock with each other. The first arc-shaped groove and the second arc-shaped groove are respectively opened on the upper housing and the lower housing. The inner walls of the first arc-shaped groove and the second arc-shaped groove are respectively provided with a first slot and a second slot that interlock with each other. The fixing plate is fixed in the first slot and the second slot. The inner walls of the first arc-shaped groove and the second arc-shaped groove are respectively provided with a third arc-shaped groove and a fourth arc-shaped groove that interlock with each other. The rotating plate is rotatably fitted in the third arc-shaped groove and the fourth arc-shaped groove.

[0009] Furthermore, the fixing plate is octagonal; the fixing plate is not easily moved within the first and second slots, and the fixing plate is relatively fixed to the housing.

[0010] The beneficial effects of this utility model are as follows: The laser emitted by the laser module passes through the annular glass and is then projected onto the construction surface to form a laser line. This laser line produces four breakpoints, but since the glass assembly in the laser output window can be manually rotated and adjusted, the position of the breakpoints on the construction surface can be changed, thus avoiding blind spots in the construction reference. In the initial state, the ends of multiple balls away from the spring are respectively engaged with the corresponding spherical grooves. At this time, the glass assembly and the fixed plate are relatively fixed. When the glass assembly is manually rotated and adjusted, the rotating plate rotates synchronously, forcing the balls to disengage from the spherical grooves and press against the outer surface of the fixed plate. At this time, the spring is in a compressed state, generating uniform rotational damping. When the ball moves to the next spherical groove, under the elastic force of the spring, the ball is bounced into the next spherical groove and makes a "click" sound, providing good positioning feedback. The manual rotation adjustment of the glass assembly has a good rotational feel and positioning feedback. This new laser marking instrument has the characteristics of good adjustment feel and no blind spots in the construction reference. Attached Figure Description

The laser emitting end of the laser module 5 passes through through holes on the fixed plate 3 and the rotating plate 4 in sequence and is disposed within the annular glass 11. Multiple positioning holes 6 are evenly distributed circumferentially on the rotating plate 4. Multiple spherical grooves 7 are evenly distributed circumferentially on the outer surface of the fixed plate 3. The number of spherical grooves 7 is an integer multiple (generally 2 or 3 times) of the number of positioning holes 6. Ball bearings 8 and springs 9 are sequentially disposed along their axial direction within the positioning holes 6. The end of each ball bearing 8 away from the spring 9 respectively engages with the corresponding spherical groove 7. The end of the spring 9 away from the ball bearing 8 abuts against the glass assembly.

[0017] Preferably, the glass assembly further includes a first rubber pad 10 disposed on the inner side of the annular glass 11, a second rubber pad 12 disposed on the outer side of the annular glass 11, and a glass seat 13 disposed on the outer side of the second rubber pad 12. The glass seat 13 is fixedly connected to the rotating plate 4 by screws. The first rubber pad 10 and the second rubber pad 12 serve to protect the annular glass 11.

[0018] Preferably, the annular glass 11 comprises four glass sheets arranged in a rectangular shape, with adjacent glass sheets bonded together by glass adhesive.

[0019] Preferably, the number of positioning holes 6 is 4, and the number of spherical grooves 7 is 16; when the glass assembly is manually rotated and adjusted, the glass assembly rotates 22.5 degrees to generate a positioning feedback.

[0020] Preferably, the housing 1 includes an upper housing 14 and a lower housing 15 that interlock with each other. The upper housing 14 and the lower housing 15 are fixedly connected by screws. The mounting hole 2 is formed by a first arc-shaped groove 16 and a second arc-shaped groove 17 that interlock with each other. The first arc-shaped groove 16 and the second arc-shaped groove 17 are respectively opened on the upper housing 14 and the lower housing 15. The inner walls of the first arc-shaped groove 16 and the second arc-shaped groove 17 are respectively provided with a first slot and a second slot that interlock with each other.

[0021] Preferably, the fixing plate 3 is octagonal; the fixing plate 3 is not easily moved within the first and second slots, and the fixing plate 3 is relatively fixed to the housing 1.

[0022] In use, the laser emitted by the laser module 5 passes through the annular glass 11 and is then projected onto the construction surface to form a laser line. This laser line produces four breakpoints. However, since the glass assembly can be manually rotated and adjusted, the position of the breakpoints on the construction surface can be changed, thus avoiding blind spots in the construction reference. In the initial state, the end of each ball bearing 8 away from the spring 9 is engaged with the corresponding spherical groove 7. At this time, the glass assembly and the fixing plate 3 are relatively fixed. When the glass assembly is manually rotated and adjusted, the rotating plate 4 rotates synchronously, forcing the ball bearing 8 to disengage from the spherical groove 7 and press against the outer surface of the fixing plate 3. At this time, the spring 9 is in a compressed state, generating uniform rotational damping. When the ball bearing 8 moves to the next spherical groove 7, under the elastic force of the spring 9, the ball bearing 8 is bounced into the next spherical groove 7 and makes a "click" sound, providing good positioning feedback. When the glass assembly is manually rotated and adjusted, it has a good rotational feel and positioning feedback. The laser marking instrument of this embodiment has the characteristics of good adjustment feel and no blind spots in the construction reference.
