[0030] Prevent the quantitative card from wearing the glass tube, such as Figure 1-Figure 3As shown, it includes a fixed ring seat 10 for sleeved on a glass tube 40, the glass tube 40 is made of transparent glass material, and has scale lines on the outer wall, a stand 20 is installed on the outer wall of the fixed ring seat 10, and an adjusting screw 30 is installed on the top of the stand 20; a silicone inner ring sleeve 11 is installed on the inner ring wall of the fixed ring seat 10; the stand 20 is vertically arranged between the fixed ring seat 10, and an adjusting slot 21 is opened on the top of the side of the stand 20 close to the fixed ring seat 10, and an adjustable quantitative rod 22 is installed on one side of the stand 20, and the adjustable quantitative rod 22 is arranged parallel to the fixed ring seat 10, and one end of the adjustable quantitative rod 22 is equipped with a cross-sectional size of the adjusting slot 21 and The sliding-fitting adjustment slider 23 enhances the friction and stability between the glass tube 40 and the silicone inner ring sleeve 11 installed on the inner ring wall of the fixed ring seat 10. At the same time, the silicone material is soft and will not cause scratches or wear to the glass tube 40, thereby effectively extending the service life of the glass tube 40. The adjustment groove 21 provided on the stand 20 cooperates with the adjustment slider 23 on the adjustable quantitative rod 22, so that the adjustable quantitative rod 22 can slide along the adjustment groove 21, and the position of the quantitative rod can be easily adjusted, thereby limiting the piston rod 42. This design allows the quantitative card to adapt to glass tubes 40 of different ranges, thereby improving the versatility and practicality of the quantitative card.

[0031] Furthermore, locking holes 12 connected to the bottom of the limit ring seat 41 on the glass tube 40 are symmetrically opened at both ends of the fixed ring seat 10. The fixed ring seat 10 is threadedly connected to the bottom of the limit ring seat 41 through the locking holes 12 by fixing bolts 13. Through the set locking holes 12 and fixing bolts 13, the fixed ring seat 10 can be firmly connected to the bottom of the limit ring seat 41 on the glass tube 40.

[0032] Specifically, the inner diameter of the silicone inner ring sleeve 11 is matched with the outer diameter of the glass tube 40 and the two are slid with interference fit. The thickness of the silicone inner ring sleeve 11 is 0.5-1.5mm, and the silicone inner ring sleeve 11 and the fixed ring seat 10 are an integrally formed structure, so that the silicone inner ring sleeve 11 can fit tightly on the outer wall of the glass tube 40, which not only ensures friction but also avoids wear.

[0033] It is worth noting that the cross-sections of the adjusting slider 23 and the adjusting slot 21 are both T-shaped, so that the fit between the two is tighter and more stable, and shaking or deviation caused by sliding during use is prevented.

[0034] Among them, a rotating seat 24 is installed at the center of the top surface of the adjusting slider 23, and the bottom of the adjusting screw 30 is coaxially connected to the rotating seat 24. The adjusting screw 30 is connected to the adjusting slider 23 through the rotating seat 24, so that the adjusting screw 30 can drive the adjusting slider 23 to slide in the adjusting slot 21 when rotating, thereby realizing precise adjustment of the adjustable quantitative rod 22.

[0035] In addition, a rotating disk 31 is coaxially mounted on the top surface of the adjusting screw 30 , making the rotation of the adjusting screw 30 easier and more labor-saving. The user can conveniently adjust the height of the adjusting screw 30 by rotating the disk 31 , thereby achieving precise control of the adjustable quantitative rod 22 .

[0036] The working principle of the quantitative card for preventing wear of the glass tube is as follows: the operator observes the measuring range of the glass tube 40 and the position requiring quantitative measurement, determines the initial position of the adjustable quantitative rod 22, aligns the adjusting slider 23 installed at one end of the adjustable quantitative rod 22 with the adjusting slot 21 on the stand 20, and then slides the adjustable quantitative rod 22 along the adjusting slot 21 to the predetermined position. By fine-tuning the adjusting screw 30, the position of the adjustable quantitative rod 22 can be further accurately adjusted to ensure that the limiting position of the piston rod 42 is accurate and reliable. When the piston rod 42 moves in the glass tube 40, the adjustable quantitative rod 22 will play a limiting role to prevent the piston rod 42 from exceeding the predetermined quantitative position. The movement of the piston rod 42 can be monitored by observing the scale line on the glass tube 40 to ensure accurate quantitative measurement.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
