Specific embodiments

[0026] Next, the technical solution of the present invention will be described more clearly and completely in conjunction with the accompanying drawings and through the description of the preferred embodiments of the present invention.

[0027] The present invention provides a connecting structure for conveniently installing a laser measuring tool and an accessory, including: a tool connecting structure provided on the laser measuring tool, the tool connecting structure including an inner spherical magnet; a connecting component for connecting the laser measuring tool and the accessory, the connecting component including a metal ball for cooperating with the inner spherical magnet; and a locking mechanism provided on the accessory for locking the connecting component on the accessory.

[0028] The above connecting structure of the present invention makes the installation and disassembly operations between the laser measuring tool and the accessory, as well as the angle adjustment operation of the laser measuring tool, simpler and more convenient, saving the time for installation and adjustment, and improving the usability and user experience of the laser measuring tool.

[0029] As Figure 1 and Figure 2 shown, the connecting structure 100 for conveniently installing a laser measuring tool and an accessory in the preferred embodiment of the present invention includes: a tool connecting structure 1, a connecting component 2, and a locking mechanism 3.

[0030] The tool connection structure 1 is provided on the laser measurement tool 10. Specifically, it is provided at the bottom of the laser measurement tool 10. The tool connection structure 1 includes an inner spherical magnet 11 which has a concave spherical surface. Preferably, the inner spherical magnet 11 is wrapped by a rubber anti-slip layer 12 for providing a damping effect when cooperating with the metal spherical ball 21 described below and positioning the laser measurement tool 10 at a desired position. The inner spherical magnet 11 and the rubber anti-slip layer 12 are assembled inside the housing of the laser measurement tool 10, and the concave spherical surface of the inner spherical magnet 11 faces the outside of the laser measurement tool 10 for facilitating cooperation with the metal spherical ball 21.

[0031] Preferably, the tool connection structure 1 further includes a connection nut 13 which is embedded inside the housing of the laser measurement tool 10 and is close to the inner spherical magnet 11. On the one hand, the connection nut 13 can cooperate with the connection screw 22 described below; on the other hand, it can also be connected to conventional accessories on the market. Conventional accessories on the market usually have a connection screw provided at the top, so that the laser measurement tool with the connection structure of the present utility model can be connected to both the accessories of the present utility model and common accessories on the market, thus having good versatility.

[0032] As Figure 2 and Figure 3 shown, the connection component 2 includes opposite first and second ends. The first end is provided with a metal spherical ball 21, and the second end is provided with a connection screw 22. The metal spherical ball 21 can be adsorbed by the inner spherical magnet 11 of the tool connection structure 1 and cooperate with each other; the connection screw 22 is used to cooperate with the above-mentioned connection nut 13.

[0033] Furthermore, the connection component 2 further includes a non-circular assembly main body 23 which is located between the metal spherical ball 21 and the connection screw 22 and is used to assemble the connection component 2 to the accessory 4. Correspondingly, the accessory 4 has an assembly hole 43 which matches the shape of the assembly main body 23 for cooperating with the assembly main body 23. Here, the non-circular design of the assembly main body 23 is to be able to limit its rotational movement relative to the accessory 4 after being installed on the accessory 4. Specifically, in this preferred embodiment, the assembly main body 23 has an elliptical outer shape, and the assembly hole 43 is an elliptical hole; in other embodiments, the assembly main body can also adopt a square or other suitable shape.

[0034] Based on the above design, the user can selectively use the cooperation between the metal spherical ball 21 and the inner spherical magnet 11 or the cooperation between the connection screw 22 and the connection nut 13 to realize the connection between the laser measurement tool 10 and the accessory 4. As Figure 1 and Figure 4As shown, it respectively shows the connection achieved through the metal sphere 21, the connecting screw 22 and the laser measuring tool 10. When choosing the connection method where the metal sphere 21 cooperates with the inner spherical magnet 11, the connecting component 2 is installed on the accessory 4 with the first end facing upwards, so that the metal sphere 21 is adsorbed by the inner spherical magnet 11 and they cooperate with each other, thus achieving the connection between the connecting component 2 and the laser measuring tool 10. In this connection method, the user can freely adjust the use angle by swinging the laser measuring tool 10, and under the damping effect of the rubber anti-slip layer 12, the laser measuring tool 10 can automatically be fixed at the adjusted angle, making the angle adjustment operation very convenient. When choosing the connection method where the connecting screw 22 cooperates with the connecting nut 13, the connecting component 2 is installed on the accessory 4 with the second end facing upwards, so that the connecting screw 22 cooperates with the connecting nut 13, thus achieving the connection between the connecting component 2 and the laser measuring tool 10. Therefore, when encountering common accessories on the market, the laser measuring tool of the present utility model can also be connected to match them, with strong versatility.

[0035] In this preferred embodiment, the accessory 4 is a tripod. Those skilled in the art can understand that the connection structure of the present utility model is also applicable to other accessories, such as a support frame that can be fixed on an object. Therefore, the present utility model does not limit the specific structure of the accessory.

[0036] As Figure 5 and Figure 6 shown, the connection structure 100 further includes a locking mechanism 3 provided on the accessory 4, which includes a rotating shaft 31, a buckle 32, and a torsion spring 33. Among them, the buckle 32 is rotatably installed on the accessory 4 through the rotating shaft 31. Specifically, the buckle 32 has an eccentrically designed abutting portion 320 for abutting on the upper part of the assembly main body 23 of the connecting component 2. The torsion spring 33 is installed on the rotating shaft 31, and it applies a reset torsion force to the buckle 32, so that the buckle 32 is in the locked position under normal conditions, that is, the position where the abutting portion 320 abuts against the assembly main body 23, that is Figure 5 the state shown.

[0037] Preferably, in order to achieve the stability of locking, the outer surface of the assembly main body 23 has symmetrically arranged first inclined surface 231 and second inclined surface 232. These two inclined surfaces are symmetric about the horizontal bisecting plane A of the assembly main body 23, and these two inclined surfaces respectively extend from the end of the assembly main body 23 towards the horizontal bisecting plane A and outwards. The abutting portion 320 abuts on the first inclined surface 231 or the second inclined surface 232. When the metal sphere 21 cooperates with the inner spherical magnet 11, the abutting portion 320 abuts on the first inclined surface 231. When the connecting screw 22 cooperates with the connecting nut 13, the abutting portion 320 abuts on the second inclined surface 232. Therefore, no matter which connection method is selected, the locking mechanism 3 can effectively prevent the connecting component 2 from moving upwards, making the locking more stable.

[0038] When it is necessary to unlock the locking mechanism 3, rotate the buckle 32 to overcome the torsion force of the torsion spring 33, so that the abutting portion 320 leaves the assembly main body 23. At this time, the user can switch between the metal ball 21 and the connecting screw 22 to select a suitable connection method. After the switching is completed, release the buckle 32. Under the action of the torsion spring 33, the buckle 32 automatically reaches the locking position, locking the connecting component 2 on the accessory 4. This locking mechanism is convenient to operate and has a more stable locking effect.

[0039] The above specific embodiments only describe the preferred embodiments of the present invention, rather than limiting the protection scope of the present invention. Without departing from the concept and spirit of the present invention, various deformations, substitutions and improvements made by those of ordinary skill in the art to the technical solutions of the present invention based on the written description and drawings provided by the present invention shall fall within the protection scope of the present invention. The protection scope of the present invention is determined by the claims.
