[0035] like Figures 1 to 7 As shown, an embodiment of the utility model provides a telescopic pregnancy test stick, including a protective tube 1, in which a pregnancy test stick body 6 is movably provided, a movable groove 5 for the pregnancy test stick body 6 to move is provided in the protective tube 1, and a movable plate 11 is arranged on the top of the pregnancy test stick body 6, the movable plate 11 is movably arranged in the movable groove 5, a plurality of limiting holes 13 are penetrated along the circumference direction of the movable plate 11, a first spring 4 is provided on the top of the movable plate 11, and a limiting component 9 for limiting the plurality of limiting holes 13 is provided on the protective tube 1.
[0036] Specifically, when the pregnancy test stick body 6 is not in use, one end of the pregnancy test stick body 6 is located outside the protective tube 1, and the other end is squeezed by the movable plate 11 to the first spring 4, and the limiting hole 13 is limited by the limiting assembly 9, so that the pregnancy test stick body 6 is limited in the movable groove 5. When the length of the pregnancy test stick body 6 needs to be adjusted, the limiting of the multiple limiting holes 13 is released by the limiting assembly 9. At this time, the movable plate 11 is pushed to slide along the movable groove 5 under the elastic force of the first spring 4, thereby pushing the pregnancy test stick body 6 toward the outside of the protective tube 1 to achieve the change of the length of the pregnancy test stick body 6. At the same time, the first spring 4 applies a thrust to the pregnancy test stick body 6 to ensure the stability of the pregnancy test stick body 6. The overall operation is simple, and it is convenient to quickly adjust the length of the pregnancy test stick body 6. There is no need to manually hold down the pregnancy test stick to limit it, which is convenient for people to use, and solves the problem that the existing telescopic pregnancy test stick requires manual continuous pressing of the slider 15 to achieve the fixation of the pregnancy test stick after it extends out of the shell, thereby causing inconvenience for people to use.
[0037] It should be noted that an opening is provided at the bottom of the protective tube 1 for the pregnancy test stick body 6 to pass through, and the opening is connected to the movable groove 5. The diameter of the movable plate 11 is larger than the diameter of the pregnancy test stick body 6, and the opening is smaller than the diameter of the movable groove 5. The advantage of this is that the movable plate 11 can be used to limit the pregnancy test stick body 6 to prevent the pregnancy test stick body 6 from moving inside the protective tube 1.
[0038] like Figure 1 and Figure 7As shown, in this embodiment, the limiting assembly 9 includes a movable plate 92, which is movably arranged in the protective tube 1, and a movable groove 94 is provided in the protective tube 1 for the movable plate 92 to move, a limiting block 91, which is fixedly connected to the movable plate 92 and slidably arranged between the movable groove 94 and the movable groove 5, and the limiting block 91 is suitable for limiting the limiting hole 13, a traction rope 95, a first end of which is fixedly connected to an end of the movable plate 92 away from the limiting block 91, and a second spring 93 is provided on the outer sleeve of the traction rope 95, and the second spring 93 is located in the movable groove 94, a control ring 96, which is sleeved and rotatably arranged on the outer wall of the protective tube 1, and the second end of the traction rope 95 extends to the outer wall of the protective tube 1 and is fixedly connected to the control ring 96, a slider 15 is relatively fixedly connected to the control ring 96, and a sliding groove 16 is provided on the protective tube 1 for the slider 15 to slide, and a groove 14 is provided in the middle of the control ring 96, and the traction rope 95 is fixedly connected in the groove 14. Specifically, by rotating the control ring 96, the control ring 96 The movable plate 92 is driven to move by the traction rope 95, and the movable plate 92 drives the limit block 91 to release the limit on the limit hole 13, so that the first spring 4 pushes the pregnancy test stick body 6 to slide out along the movable groove 5. Similarly, when the pregnancy test stick body 6 needs to be put into the movable groove 5, it is only necessary to push the pregnancy test stick body 6 toward the movable groove 5 so that the pregnancy test stick body 6 drives the movable plate 11 to squeeze the first spring 4. When the limit hole 13 corresponds to the limit block 91, the limit block 91 realizes the limit of the limit hole 13 under the elastic force of the second spring 93, that is, the limit of the pregnancy test stick body 6 is realized. The overall operation is simple, which is convenient for realizing the rapid limit of the limit hole 13 and improving the user experience of the personnel; it should be noted that the number of limit blocks 91 and movable plates 92 is the same as the limit hole 13, and multiple movable plates 92 are connected to the control ring 96 through the traction rope 95. The groove 14 can provide activity space for the activity of the traction rope 95 to avoid damage to the traction rope 95 when the control ring 96 rotates.
[0039] like Figure 3 and Figure 4 As shown, in the present embodiment, a tube cover 3 is further included, which is clamped with the protective tube 1, and a clamping ring 12 is fixedly connected at the connection between the protective tube 1 and the tube cover 3. A placement groove 7 is provided inside the tube cover 3 for the test end of the pregnancy test stick body 6 to be inserted, and a sponge pad 8 is fixedly connected in the placement groove 7. Specifically, the clamping connection between the tube cover 3 and the protective tube 1 can be achieved through the clamping ring 12. At the same time, the cooperation of the placement groove 7 and the sponge pad 8 can protect the test end of the pregnancy test stick body 6, avoid damage to the pregnancy test stick body 6, and ensure its normal use.
[0040] like Figure 1 , Figure 5 and Figure 6As shown, in the present embodiment, a display window 10 is provided on the pregnancy test stick body 6, and a perspective plate 2 is provided on the protective tube 1 facing the display window 10. Specifically, the perspective plate 2 facilitates people to view the display window 10, thereby improving the convenience of use, wherein the perspective plate 2 is made of a transparent acrylic plate.
[0041] Working principle:
[0042] When using the pregnancy test stick body 6, by opening the barrel cover 3 and then rotating the control ring 96, the control ring 96 drives the movable plate 92 to move through the traction rope 95, and the movable plate 92 drives the limit block 91 to release the limit on the limit hole 13, so that the first spring 4 pushes the pregnancy test stick body 6 to slide out along the movable groove 5. Similarly, when the pregnancy test stick body 6 needs to be put into the movable groove 5, it is only necessary to push the pregnancy test stick body 6 toward the movable groove 5, so that the pregnancy test stick body 6 drives the movable plate 11 to squeeze the first spring 4, and wait until the limit hole 13 is in contact with the movable plate 11. When the limit block 91 corresponds, the limit block 91 realizes the limitation of the limit hole 13 under the elastic force of the second spring 93, that is, the limitation of the pregnancy test stick body 6, and then the tube cover 3 and the protective tube 1 are snapped into place. The overall operation is simple, and it is convenient to realize the rapid adjustment of the length of the pregnancy test stick body 6. There is no need to manually press the pregnancy test stick to limit it, which is convenient for people to use. It solves the problem that the existing telescopic pregnancy test stick requires manual continuous pressing of the slider 15 to achieve the fixation of the pregnancy test stick after it is extended out of the shell, thereby causing inconvenience for people to use.
