[0003] The back basically means the part of the human skeleton formed by the two shoulders and the upper back. This part is most suitable for weight-bearing. Before back beauty treatment, the size of the customer's back needs to be measured and recorded with a measuring tape. After the beautician completes the technique, the size of the customer's back needs to be measured and recorded again with a measuring tape.

[0004] The existing Chinese patent document publication number CN216454990U is a back adjustment measuring ruler that adjusts the position of the second ruler through structures such as a first mounting column and a first adjustment sleeve, thereby solving the problem that the current measurement of the size of the human back using a conventional ruler is cumbersome to operate and has large errors, which affects the measurement of the size of the human back. The position of the second ruler and other structures can be adjusted, and the measurement operation is simple, which is convenient for measuring the size of the human back.

[0005] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0006] The existing back adjustment measuring ruler uses the support of the first ruler to make the second ruler slide on the first ruler, and the third ruler slide on the second ruler to measure the back size. However, since the first ruler needs to be held and fixed, the adjustment process of the second ruler and the third ruler is greatly restricted and the operation is more troublesome. Utility Model Content

[0024] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0025] Embodiment 1:

[0026] This embodiment introduces a specific structure of a back adjustment measuring ruler. Figure 1-Figure 4As shown, it includes a ruler 3 and a fixing assembly 1 arranged on the top of the ruler 3, the fixing assembly 1 includes a central support 103, two support rods 102 are processed on both sides of the central support 103, one end of the two support rods 102 is provided with a base 106, the top of the base 106 is provided with a connecting belt 104, and one end of the connecting belt 104 is connected to a counterweight block 101;

[0027] The connecting belt 104 is made of rubber material, so that the connecting belt 104 has a bendable property, so that the connecting belt 104 can fit with the shoulder surface when it passes over the shoulder of the user, and the counterweight block 101 can be used for counterweighting, so that the base 106 and the counterweight block 101 are respectively located on both sides of the shoulder;

[0028] Secondly, in order to prevent the counterweight 101 from causing damage to the user's skin, tendons and bones when the ruler 3 and related connecting parts are counterweighted, a latex layer is wrapped around the outside of the counterweight 101, so that the counterweight 101 has elasticity when counterweighted;

[0029] At the same time, when the two counterweights 101 are placed on the shoulders of the user through the two connecting belts 104, the ruler 3 connected to the central support 103 can be vertically moved down along the cervical spine of the user, which is conducive to ensuring the measurement accuracy of the ruler 3 and conveniently controlling the movement of the measuring ruler connected to the ruler 3;

[0030] Furthermore, for convenience, the base 106 is fixed to one end of the two support rods 102, so that the base 106 can be hung on the back of the user through the counterweight block 101 and the connecting belt 104. Figure 3 As shown, one end of the four support rods 102 is processed with a threaded rod 105. By inserting the two threaded rods 105 on one side into the inside of a base 106 and threading nuts on the outside of one end of the threaded rod 105, a base 106 can be fixed to one end of the two support rods 102 on one side.

[0031] By adopting the above technical solution:

[0032] The above design connects a central support 103 to the top of the ruler 3, and connects two support rods 102 with a base 106 and two threaded rods 105 on both sides of the central support 103. When the counterweight 101 is passed from the user's back around the shoulders and hung in front of the chest, the connecting belt 104 can be supported on the user's shoulders. Therefore, by hanging the ruler 3 on the user's back, it is helpful to control the ruler 3 connected to the central support 103 to go vertically down along the user's cervical spine according to actual conditions, freeing the measurer's hands and facilitating the position adjustment of the other two rulers connected to the ruler 3 in the prior art.

[0033] Embodiment 2:

[0034] Based on Example 1, this example introduces the connection between the fixing assembly 1 and the ruler 3. Figures 2 to 4 As shown, the inner part of the center support 103 is processed with a limit groove 2, and the surface of the top of the ruler 3 is processed with a slide bar 5;

[0035] By making the slide bar 5 slidably connected to the inside of the limit groove 2, the relative position of the ruler 3 and the central support 103 can be adjusted, so as to control the starting point of the ruler 3 to achieve the effect of accurate measurement;

[0036] Secondly, in order to fix the ruler 3 to the surface of the central support 103, the ruler 3 is hung at a fixed height, such as Figure 2 and Figure 4 As shown, the top of the ruler 3 is threadedly connected with a tightening screw 4. By supporting one end of the tightening screw 4 on the surface of the center support 103, the friction between the ruler 3 and the center support 103 can be increased, thereby limiting the ruler 3 from sliding toward the bottom relative to the center support 103 due to the influence of gravity.

[0037] By adopting the above technical solution:

[0038] The above design allows the slide bar 5 processed on one side of the top of the ruler 3 to be slidably connected to the limit groove 2 processed inside the center support 103. By adjusting the threaded connection between the tightening screw 4 and the ruler 3, one end of the tightening screw 4 can apply pressure to the surface of the center support 103, thereby increasing the friction between the center support 103 and the ruler 3, so that the ruler 3 is at a fixed height on one side of the center support 103, which is beneficial to controlling the starting point of the ruler 3 measurement to achieve the effect of accurate measurement.

[0039] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
