[0002] A spirit level support is a component used to adjust and fix a spirit level. It is often called a "support" or "foot cup". It is height-adjustable via threads to ensure that the spirit level remains level and stable during use. It is widely used for leveling infrared spirit levels.

[0003] However, the existing level support structure is relatively simple, mainly using an external threaded rod or an internal threaded cylinder in conjunction with a threaded cylinder or screw at the bottom of the equipment. This results in two main types of existing level supports, which limits their use and makes it impossible to adjust between the two different connection methods, thus reducing the ease of installation. At the same time, the anti-slip sleeve and the support shaft are connected as one piece, making it impossible to replace the anti-slip sleeve when it is damaged, further reducing the convenience of subsequent maintenance.

The external threads are threaded to the first threaded hole, and the first threaded post is threaded to the second threaded hole.

[0009] Preferably, one end of the support shaft has a tapered structure, the diameter of the positioning support ring is larger than the diameter of the support shaft, and the outer diameter of the positioning support ring is equal to the outer diameter of the anti-slip sleeve.

[0010] Preferably, the outer wall of the support shaft is uniformly provided with limit slots, and the inner wall of the anti-slip sleeve is uniformly provided with positioning guide rails corresponding to the limit slots, and the positioning guide rails are plugged into the limit slots.

[0011] Preferably, a limiting ring is provided on the inner side of the top circumference of the anti-slip sleeve, and a groove for matching the limiting ring is provided on the top of the support shaft. When the anti-slip sleeve is engaged with the outside of the support shaft, the top of the limiting ring and the top of the support shaft are on the same horizontal plane.

[0012] Preferably, the diameter of the positioning plate is equal to the diameter of the anti-slip sleeve, and the outer wall of the center end of the anti-slip sleeve is evenly distributed with anti-slip ridges, and the side of the positioning plate that contacts the anti-slip sleeve is provided with anti-slip texture.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 One embodiment of this utility model provides: a level support leg that is easy to install, comprising:

[0024] The support shaft 1 has a positioning support ring 11 integrally formed on its outer wall, and a second threaded hole 14 is formed in the center of the support shaft 1; an anti-slip sleeve 2 is fitted on the outside of the support shaft 1; a positioning pressure plate 3 has a threaded connecting cylinder 31 integrally formed in the center of the positioning pressure plate 3, and an external thread 33 is formed on the outer wall of the threaded connecting cylinder 31. A first threaded post 32 is formed at one end of the threaded connecting cylinder 31, and an internal thread 34 is formed on the inner wall of the threaded connecting cylinder 31. The external thread 33 is threaded to the first threaded hole 13, and the first threaded post 32 is threaded to the second threaded hole 14. Through the threaded connection between the external thread 33 and the first threaded hole 13 or the first threaded post 32 and the second threaded hole 14, different installation methods can be used to realize the installation and adjustment of the device. At the same time, through its threaded connection, different height adjustment can be realized, which facilitates the horizontal height adjustment of the infrared level.

[0025] Furthermore, one end of the support shaft 1 has a tapered structure, the diameter of the positioning support ring 11 is larger than the diameter of the support shaft 1, and the outer diameter of the positioning support ring 11 is equal to the outer diameter of the anti-slip sleeve 2. The positioning support ring 11 is mainly designed to provide abutment support for the anti-slip sleeve 2, ensuring the stability of the anti-slip sleeve 2 during installation and engagement.

[0026] Furthermore, the outer wall of the support shaft 1 is uniformly provided with limiting grooves 12, and the inner wall of the anti-slip sleeve 2 is uniformly provided with positioning guide rails 21 corresponding to the limiting grooves 12. The positioning guide rails 21 and the limiting grooves 12 are plugged into each other. Through the limiting plug-in connection between the positioning guide rails 21 and the limiting grooves 12, the shaft has good self-locking performance. Thus, the thread adjustment of the device can be achieved by holding the anti-slip sleeve 2, which facilitates the connection adjustment at different heights.

[0027] Furthermore, a limiting ring is provided on the inner side of the top circumference of the anti-slip sleeve 2, and a groove adapted to the limiting ring is opened at the top of the support shaft 1. When the anti-slip sleeve 2 is engaged with the outside of the support shaft 1, the top of the limiting ring and the top of the support shaft 1 are on the same horizontal plane. The diameter of the positioning pressure plate 3 is equal to the diameter of the anti-slip sleeve 2, and anti-slip ridges are evenly distributed on the outer wall of the center end of the anti-slip sleeve 2. Anti-slip textures are provided on the side of the positioning pressure plate 3 that is in contact with the anti-slip sleeve 2. The engagement and compression positioning of the anti-slip sleeve 2 can improve the stability of the anti-slip sleeve 2 installation. At the same time, the compression contact between the positioning pressure plate 3 and the anti-slip textures of the anti-slip sleeve 2 increases the friction, making the compression more stable. In addition, when the anti-slip sleeve 2 is rotated by hand, it avoids loosening of the threads between the external thread 33 and the first threaded hole 13 or the first threaded post 32 and the second threaded hole 14, ensuring the overall stability of the device installation.

[0028] Furthermore, the first threaded hole 13 and the second threaded hole 14 are coaxially distributed, and the first threaded hole 13 is located below the opening end of the second threaded hole 14. The distribution length of the external thread 33 is less than the height of the first threaded post 32. The internal thread 34 has the same specifications as the second threaded hole 14. The outer wall of the positioning plate 3 is uniformly provided with positioning grooves. The opening of these positioning grooves is mainly used to cooperate with the crescent wrench to realize the rotation of the positioning plate 3, thereby realizing the threaded tight positioning between the external thread 33 and the first threaded hole 13 or the first threaded post 32 and the second threaded hole 14.

[0029] Working principle: When using this utility model, depending on the different installation methods, the splicing of the device in different states can be achieved by adjusting the threads between the external thread 33 and the first threaded hole 13 or the first threaded post 32 and the second threaded hole 14. At the same time, the anti-slip sleeve 2 is fitted and pressed between the positioning support ring 11 and the positioning pressure plate 3. The device can then be installed by holding the anti-slip sleeve 2 and cooperating with the bottom connector of the infrared level through the internal thread 34 or the first threaded post 32.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
