[0002] Semi-automatic urine analyzers are commonly used urine examination devices in hospitals and medical examination institutions. The applicant previously applied for a utility model patent for a semi-automatic urine analyzer with an application number of CN202222038877.2. The semi-automatic urine analyzer is internally provided with a scanning part, which mainly consists of a belt pulley, a stepping pulley, a stepping belt connecting the belt pulley and the stepping pulley, and a scanning sensor fixed on the stepping belt; when the test strip is conveyed to the scanning position, the scanning sensor moves back and forth following the stepping belt to scan the test strip. However, there are still certain problems with this technology, that is, after the semi-automatic urine analyzer is used for a certain period of time, the stepping belt will become loose. Therefore, the semi-automatic urine analyzer needs to be repaired relatively frequently during use, increasing the use cost. Summary of the Utility Model

[0003] In order to solve the above problems, the present application provides a mobile scanning mechanism, which can stretch the stepping belt to keep the stepping belt in a tight state and reduce the maintenance frequency.

[0005] When the stepping belt becomes loose, the present utility model applies a driving force to the second mounting seat away from the driving component side through the spring, so that the second mounting seat moves away from the driving component side, and the stepping belt can maintain a tight state. Furthermore, the mobile scanning mechanism can be continuously used for a period of time, reducing the maintenance frequency.

In addition, a fixing cavity is provided on the second mounting seat, a positioning column is provided in the fixing cavity, and a positioning cavity is provided in the installation cavity; one end of the spring is sleeved on the positioning column, and the other end is inserted into the positioning cavity. In this way, the spring can be positioned to prevent the spring from shifting or falling off.

[0007] The driving assembly includes: a first mounting base; a driving motor mounted on the first mounting base; a driving wheel mounted on the main shaft of the driving motor; a driven wheel is provided on the second mounting base, and the stepping belt connects the driving wheel and the driven wheel.

[0008] As another preferred solution, a guiding column is further connected between the driving assembly and the second mounting base, and the scanning assembly is also connected to the guiding column.

Detailed implementation manners

[0020] In order to enable those skilled in the art of this technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments.

[0021] Embodiment

[0022] As Figures 1-5 shown, this embodiment discloses a mobile scanning mechanism, including: a driving component, a support frame 700, a second mounting seat 800, a stepping belt 500, a scanning component, and a spring 820.

[0023] Among them, the driving component includes a first mounting seat 100, a driving motor 300 mounted on the first mounting seat 100, and a driving wheel 200 mounted on the main shaft of the driving motor 300.

[0024] The support frame 700 is disposed opposite to the first mounting seat 100, and a mounting cavity 720 is provided thereon. The second mounting seat 800 is slidably mounted in the mounting cavity 720. A driven wheel 900 is provided on the second mounting seat 800, and an opening 730 is formed on the cavity wall of the mounting cavity 720. One end of the stepping belt 500 is connected to the driving wheel 200, and the other end passes through the opening 730 and is then connected to the driven wheel 900. The scanning component is connected to the stepping belt 500. When the driving motor 300 rotates forward and backward, the stepping belt 500 rotates forward and backward, driving the scanning component to reciprocate along with the stepping belt 500 to scan the test strip.

[0025] As another implementation of this embodiment, a guiding column 400 is further connected between the first mounting seat 100 and the second mounting seat 800. The number of guiding columns 400 can be set to two. The two guiding columns 400 are respectively located on both sides of the stepping belt 500, and both ends of the scanning assembly are respectively slidably connected to the two guiding columns 400. When driving the scanning assembly to reciprocate along with the stepping belt 500, the scanning assembly also slides along the two guiding columns 400. Due to the supporting and guiding effect of the guiding columns 400, the scanning assembly can move more smoothly.

[0026] In addition, a spring 820 is arranged between the second mounting seat 800 and the inner wall of the mounting cavity 720, and it is used to push the second mounting seat 800 towards the side away from the driving assembly, so as to keep the stepping belt 500 in a taut state. The number of springs 820 can be set to two. The two springs are respectively located at both ends of the second mounting seat 800. Setting the number of springs 820 to two can push the second mounting seat 800 more smoothly.

[0027] Specifically, as Figure 4 、 5 shown, a fixing cavity 830 is arranged on the second mounting seat 800, a positioning column 810 is arranged in the fixing cavity 830, and a positioning cavity 710 is arranged in the mounting cavity 720. During installation, one end of the spring 820 is sleeved on the positioning column 810, and the other end is inserted into the positioning cavity 710. In this way, the spring can be positioned to prevent the spring from shifting or falling off.

[0028] The scanning assembly includes a moving assembly 600 and a scanning sensor 1000 installed at the lower end of the moving assembly 600. Specifically, the moving assembly 600 includes two sliding sleeves respectively sleeved on the two guiding columns 400, and a clamping plate connected to the two sliding sleeves and clamping on the stepping belt 500; the scanning sensor 1000 is arranged at the lower end of the sliding sleeve. When the scanning assembly reciprocates along with the stepping belt 500, the scanning sensor 1000 scans the test strip.

[0029] In the initial state of the moving and scanning mechanism of this embodiment, the spring 820 is in a compressed state. During use, when the stepping belt 500 becomes loose, the spring 820 applies a pushing force to the second mounting seat 800 towards the side away from the first mounting seat 100, causing the second mounting seat 800 to move towards the side away from the first mounting seat 100, increasing the distance between the first mounting seat 100 and the second mounting seat 800, so that the stepping belt 500 can be kept in a taut state, and further enabling the moving and scanning mechanism to be continuously used for a period of time and reducing the maintenance frequency.

[0030] It should be noted that all the features disclosed in this specification, or all the steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.

[0031] In addition, the above specific embodiments are exemplary.
