[0003] A utility model patent for the installation structure of a lens column of a foot measuring instrument is disclosed on the Chinese Patent Network, and its authorization announcement number is CN213188402U. Although this device can install and fix the lens column through the cooperation of a positioning column, a positioning cylinder, a limiting plate and a locking rod, however, due to the semicircular structure design at the bottom of this lens column, the contact area with the upper base of the foot measuring instrument is small, resulting in relatively poor stability of the installation of this lens column; and this device does not have an installation structure for pre-stably and accurately positioning the lens column before installation, and through the positioning method of the cooperation of the positioning column and the positioning cylinder, it is difficult to accurately position the lens column before installation, thus resulting in the need to frequently adjust and twist the position of the lens column during the actual installation process, making the assembly of the limiting plate not fast and convenient enough.

[0004] Therefore, a lens column of a foot measuring instrument with high stability that is convenient for accurate positioning and installation is specifically proposed to solve the above technical problems. Content of the Utility Model

[0008] Further, there are three positioning posts, and the three positioning posts are distributed in a triangular structure.

[0009] Further, the boss is designed in a semi-circular structure.

[0010] Further, the magnetic block is a permanent magnet block.

[0011] Further, the lens post is designed in an arc semi-cylindrical structure that is narrower at the top and wider at the bottom.

[0012] Further, the lens post is made of aluminum alloy.

[0013] Further, a buffer pad is further included. A buffer pad is provided between the bottom of the lens post and the boss, and through holes corresponding to the positioning posts, magnetic blocks, positioning holes, card holes, and wire passing holes are respectively formed in the buffer pad.

Detailed Embodiments

[0021] The present utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which the currently preferred embodiments of the present utility model are shown. However, the present utility model can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the present utility model to those skilled in the art.

[0022] Example: A lens column of a high-stability foot inspection instrument provided by the present utility model, see Figures 1 - 5 As shown, it includes a lens column 1, a column cover 3, a mounting column 10, a positioning cylinder 11, a limiting plate 12, a support structure and a clamping structure. The lens column 1 is designed as an arc-shaped semi-cylindrical structure that is narrower at the top and wider at the bottom, which is beneficial to improving the stability of the structure. And the lens column 1 is made of aluminum alloy material, with high strength and good heat dissipation effect. The front side of the lens column 1 is clamped with the column cover 3 through the clamping structure. A lens mounting hole 33 is opened in the middle of the upper side of the column cover 3. Positioning holes 5 and wire passing holes 9 are respectively opened at the bottom of the lens column 1. The mounting column 10 is arranged at the lower side inside the lens column 1. A positioning cylinder 11 corresponding to and communicating with the positioning hole 5 is arranged in the middle of the inner bottom of the lens column 1. The limiting plate 12 is assembled on the mounting column 10 through screws to clamp and fix the positioning cylinder 11. A support structure is arranged at the bottom of the lens column 1. The support structure includes a boss 2, a positioning post 4 and a magnetic block 6. The boss 2 is arranged at the front side of the bottom of the lens column 1, and the boss 2 is designed as a semi-circular structure, which is beneficial to increasing the contact area with the base of the foot inspection instrument, and thus is beneficial to further improving the installation stability of the lens column 1. The positioning posts 4 are respectively arranged at the bottoms of the lens column 1 and the boss 2. The number of the positioning posts 4 is three, and the three positioning posts 4 are distributed in a triangular structure, which is beneficial to forming a stable positioning structure. The magnetic block 6 is embedded in the middle of the bottom of the boss 2. The magnetic block 6 is a permanent magnet block with strong magnetism and large magnetic attraction. Through the auxiliary cooperation of the positioning post 4 and the magnetic block 6, it is beneficial to accurately position and install the lens column 1.

[0023] Further, see Figures 3 - 5 As shown, the clamping structure includes a buckle 30, a convex block 31 and a protrusion 32. The buckle 30 is arranged in the middle of the lower side of the column cover 3. A clamping hole 8 that is clamped with the buckle 30 is opened in the middle of the boss 2. The convex block 31 is arranged at the upper end of the column cover 3, and a positioning groove 100 that is clamped with the convex block 31 is opened at the front side of the inner top of the lens column 1. The protrusions 32 are arranged at intervals on the side of the lens column 1, and clamping grooves 101 that can be clamped with the protrusions 32 are respectively opened at the front side edges of the lens column 1. By vertically clamping the column cover 3 on the lens column 1, it can support the shell of the lens column 1, and thus is beneficial to improving the stability of the structure of the lens column 1.

[0024] In addition, see Figures 1 - 4As shown in the figure, it further includes a buffer pad 7. A buffer pad 7 is provided between the bottom of the lens column 1 and the boss 2, and through holes corresponding to the positioning posts 4, magnetic blocks 6, positioning holes 5, card holes 8 and wire passing holes 9 are respectively formed on the buffer pad 7. The buffer pad 7 is beneficial to improving the tightness of the fit between the bottom of the lens column 1 and the boss 2 and the base of the foot inspection instrument, and further beneficial to further improving the stability of the installation of the lens column 1.

[0025] When the lens column 1 needs to be installed, first, the positioning cylinder 11 on the lens column 1 is sleeved on the positioning rod of the base of the foot inspection instrument. As the lens column 1 descends, when its bottom contacts the base of the foot inspection instrument, the magnetic attraction between the magnetic block 6 and the base of the foot inspection instrument is used to ensure that the lens column 1 can be placed stably and horizontally. Then, by using the three positioning posts 4 distributed in a triangular structure, just gently rotate the lens column 1 so that the positioning posts 4 on it can accurately insert into the corresponding positioning slot holes on the base of the foot inspection instrument, thus realizing the precise installation and positioning of the lens column 1. Subsequently, use screws to fix the limiting plate 12 on the mounting post 10 to complete the main steps of the installation. During the installation of the lens column 1, after the above operations are completed, align the convex block 31 on the column cover 3 with and abut against the positioning slot 100 at the top of the lens column 1. Then, push the column cover 3 towards the inside of the lens column 1 until the buckle 30 elastically engages in the card slot 101 on the front edge of the lens column 1. At the same time, the protrusion 32 on the column cover 3 also forms a snap-fit with the card slot 101, so that the installation of the column cover 3 can be conveniently completed. In addition, since the lens column 1 is designed with an arc-shaped semi-cylindrical structure that is narrower at the top and wider at the bottom and is equipped with a boss 2 as a strengthening support structure, the contact area between the lens column 1 and the base of the foot inspection instrument can be significantly increased, which is further beneficial to enhancing the stability and firmness of the installation of the lens column 1.

[0026] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
