In this way, the laser emitter body needs to be used together with a placement rack. The existing placement rack is fixed to the outer wall of the laser emitter body. In this form of direct fixing of the rack, when the laser emitter body is erected following the rack, the laser emitter body cannot be automatically leveled, resulting in the laser emitter body being skewed during use, causing inaccurate measurement and positioning.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] The present utility model provides a laser emitter with an automatic leveling function as Figure 1-6 shown, including a connecting plate 1, and further including:

[0029] A prism bracket, the prism bracket is arranged at the bottom end of the connecting plate 1, the prism bracket is used for supporting the connecting plate 1, and a connecting bolt 101 is fixedly connected to the bottom end of the connecting plate 1, and the bottom of the connecting bolt 101 is used for connecting the prism bracket;

[0030] Specifically, the prism bracket includes:

[0031] A centering rod 2, the centering rod 2 is fixedly connected to the bottom end of the connecting bolt 101;

[0032] A connecting jacket 201, one end of the connecting jacket 201 is slidably sleeved on the outer wall of the centering rod 2, and the other end of the connecting jacket 201 is inserted and connected with a support rod 202.

[0033] Further, the prism support further includes a hinge seat 203. The hinge seat 203 is arranged at the top of the support rod 202. A plurality of diagonal braces 204 are hinged to the outer wall of the hinge seat 203. Positioning cones 205 are arranged at one ends of the plurality of diagonal braces 204 away from the hinge seat 203.

[0034] It should be noted that the connecting plate 1 is fixed to the centering rod 2 through the connecting bolts 101. With such a structural connection setting, the structure arranged at the connecting plate 1 and the centering rod 2 are on the same plumb line. After the position of the centering rod 2 is set, according to the height and position to be supported and used, the setting angle of the diagonal brace 204 is adjusted. Under the rotational support of the hinge seat 203, the diagonal brace 204 can be rotationally adjusted. After the adjustment is completed, the diagonal brace 204 can be inserted and supported through the positioning cone 205.

[0035] A containing cylinder body is arranged at the top end of the connecting plate 1. A laser emitting mechanism is arranged inside the containing cylinder body. The laser emitting mechanism includes a supporting platform 5. A hemispherical seat 6 is rotationally inserted through the middle of the supporting platform 5. A laser emitter body 7 is arranged at the top end of the hemispherical seat 6. A weight mechanism is arranged at the bottom of the hemispherical seat 6. A rolling structure is arranged between the insertion part of the hemispherical seat 6 and the supporting platform 5.

[0036] Specifically, the containing cylinder body includes a first semi-arc plate 3 and a second semi-arc plate 4. The first semi-arc plate 3 and the second semi-arc plate 4 enclose a cylinder body at the top end of the connecting plate 1. The outer wall of the supporting platform 5 is fixedly connected to the inner wall enclosed by the first semi-arc plate 3 and the second semi-arc plate 4.

[0037] It should be noted that the outer wall diameters of the first semi-arc plate 3 and the second semi-arc plate 4 are the same as the diameter of the connecting plate 1. In this way, the first semi-arc plate 3 and the second semi-arc plate 4 can be enclosed and closed at the top end of the connecting plate 1 to form a cylinder structure.

[0038] Specifically, an arc-shaped supporting groove is formed in the middle of the supporting platform 5. The hemispherical seat 6 is rotationally inserted into the arc-shaped supporting groove. The inner wall at the bottom end of the arc-shaped supporting groove is penetrated, and the weight mechanism is inserted and connected through the penetration. The rolling structure is arranged in the arc-shaped supporting groove.

[0039] Further, a plurality of bearing grooves are formed in a surrounding manner on the inner wall of the arc-shaped supporting groove. A plurality of blocking blocks 501 are arranged in a surrounding manner on the inner wall at the top end of the arc-shaped supporting groove. The rolling structure includes a plurality of balls 502. The plurality of balls 502 are respectively rotationally inserted into the plurality of bearing grooves.

[0040] It should be noted that the opening diameter of the arc-shaped bracket is the same as the outer wall diameter of the hemispherical seat 6, and the outer walls of both are smoothly processed, so as to ensure that the hemispherical seat 6 can rotate in the arc-shaped bracket. In the setting of this solution, the contact between the outer wall of the hemispherical seat 6 and the arc-shaped bracket is less through the setting of the ball 502. And through the setting of the ball 502, the sliding friction is changed into rolling friction. After the friction force is further reduced, the hemispherical seat 6 rotates more flexibly in the arc-shaped bracket. The blocking block 501 is a sponge block, which blocks at the top of the arc-shaped bracket to prevent the hemispherical seat 6 from falling from the top of the arc-shaped bracket.

[0041] Furthermore, the counterweight mechanism includes a connecting bar 601. One end of the connecting bar 601 is fixedly connected to the middle of the bottom end of the hemispherical seat 6, and a counterweight ball 602 is fixedly connected to the other end of the connecting bar 601.

[0042] Specifically, a placement groove is opened in the middle of the top end of the hemispherical seat 6, the laser emitter body 7 is arranged in the placement groove, and a plurality of extrusion bumps 603 are arranged around the inner wall of the placement groove.

[0043] It should be noted that the connecting bar 601 and the counterweight ball 602 form a whole. In this way, under the action of gravity, the counterweight ball 602 and the connecting bar 601 always point downward, and at the same time drive the hemispherical seat 6 to rotate, so that the hemispherical seat 6 and the connecting plate 1 are in the same vertical center. Since the connecting plate 1 and the centering rod 2 are in the same vertical center, the hemispherical seat 6 always remains in the same vertical center as the centering rod 2. At the same time, the laser emitter body 7 arranged at the top end of the hemispherical seat 6 can be automatically leveled, and then the laser emitter body 7 and the centering rod 2 are kept in the same plumb center. In this way, after the laser is emitted vertically upward, according to the initial positioning of the centering rod 2, the vertically emitted laser can be used for the positioning of the high-altitude formwork.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
