Description

Technical Field

[0001] The utility model belongs to the technical field of urine detection, in particular to a urine tumor screening test paper discharging mechanism. Background Art

[0002] With the rapid economic development, people's income has increased, and people are more concerned about their health. At present, physical examinations basically require going to the hospital for physical examinations. Most people are used to not taking the initiative to go to the hospital for physical examinations regularly in their normal daily lives, thus delaying the best time for treatment. Therefore, urinals with urine testing functions play a vital role in people's daily lives, allowing users to complete urine testing without going to the hospital, greatly improving the efficiency of urine testing and the convenience of urine testing for users.

[0003] At present, in urinals with urine detection function, the test strips for detection are stacked in a test strip chamber. After the test strips are dropped and pushed out from the chamber outlet, urine is dripped on the color block of each test strip. After the reaction, the test results are compared with the color card to obtain the inspection results. However, most urinals are in a humid environment. When the test strips are discharged from the chamber, humid air can easily enter the sealed chamber from the chamber outlet, causing the test strips to become damp. Therefore, it is necessary to design a chamber outlet mechanism that can smoothly complete the discharge and ensure the sealing of the chamber outlet. Utility Model Content

When the baffle plate 35 is supported upward by the connecting rod assembly 4, the sealing plate 32 is also upward, thereby driving the sealing ring 31 to seal the outlet port 25, and the spring 34 is compressed. When paper needs to be discharged, the connecting rod assembly 4 no longer supports the baffle plate 35 (that is, under the action of the screw assembly 6, the connecting rod assembly 4 rotates, and its end is away from the baffle plate 35). Under the action of gravity and the reaction force of the spring 34, the sealing ring 31 and the sealing plate 32 move downward away from the outlet port 25. The height of the distance is just enough for a test paper rack 24 to be discharged from the warehouse, so that under the action of the pushing assembly 5, they are pushed out for detection. After pushing, under the action of the screw assembly 6, the connecting rod assembly 4 provides supporting force to support the baffle plate upward to complete the sealing of the outlet port 25.

The motor is arranged at the bottom of the pushing platform 1, the screw is connected to the motor, the nut seat is arranged on the screw, the top of the nut seat is connected to the pushing assembly 5, and the bottom of the nut seat is connected to the connecting rod assembly.

[0037] In this optional solution, a new connecting rod assembly 4 and a screw assembly 6 are provided, so that the screw assembly 6 can simultaneously provide the power of the pushing assembly 5 and the supporting force of the connecting rod assembly 4. Specifically, Figure 3 As shown, the connecting rod assembly 4 includes an L-shaped transmission rod 41, a bracket 42, a guide rail 43 and a fixed shaft, wherein the bracket 42 is a triangular bracket 42, and there are two of them, which are respectively installed on both sides of the bottom of the pushing platform 1, and the two brackets 42 are connected by a fixed shaft. An L-shaped transmission rod 41 is installed at both ends of the fixed shaft, and the corners of the L-shaped transmission rod 41 are rotatably connected to the fixed shaft. The longer end of the L-shaped transmission rod 41 is located at the bottom of the sealing assembly 3, that is, below the baffle 35, and the other end of the L-shaped transmission rod 41 is inclined at a certain angle, and the guide rail 43 is placed inside the inclination, that is, the two sides of the guide rail 43 are respectively located on the inner side of the L-shaped transmission rod 41. When the guide rail 43 moves outward, it will contact the end, thereby driving the other end of the L-shaped transmission rod 41, that is, the end located below the baffle 35, to move upward, thereby providing an upward supporting force to the sealing assembly 3. When the guide rail 43 moves inward, the guide rail 43 moves away from the L-shaped transmission rod 41 , and then under the action of its own gravity, the sealing assembly 3 moves downward, the L-shaped transmission rod 41 will rotate, and the sealing assembly 3 leaves the outlet 25 to complete the paper discharge. Therefore, the sealing of the sealing assembly 3 can be completed by controlling the movement of the guide rail 43 by the screw assembly 6. The screw assembly 6 includes a motor, a screw and a nut seat, which belongs to the prior art.

The bottom of the nut seat is connected to the guide rail 43, and the top of the nut seat is connected to the pushing assembly 5, that is, the pushing plate. When the test paper needs to be detected, the nut seat moves inward to drive the pushing mechanism. At this time, the guide rail 43 is away from the L-shaped transmission rod 41, and the sealing assembly 3 moves downward and leaves the outlet 25 synchronously. The test paper rack 24 falls from the outlet 25, and the pushing assembly 5 completes the pushing synchronously. In the present application, the guide rail 43 is a U-shaped guide rail 43, and a space is reserved in the middle to accommodate the motor. The motor is fixed to the bottom of the pushing platform 1.
