[0036] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0037] like Figure 1-5 As shown, a test tube includes a tube body 1, a top cover 2, a cover plate 3, and a clamping mechanism. The top cover 2 is cylindrical with a through hole 21 in its middle, which is detachably connected to the top of the tube body 1. The cover plate 3 can be inserted into the through hole 21 to seal the through hole 21, and a flexible connecting rod 31 is fixedly connected to the cover plate 3. One end of the flexible connecting rod 31 is connected to the top cover 2.
[0038] Specifically, the clamping mechanism includes a clamping plate 41, a push rod 42, a control sleeve 43, and a push block 44. The clamping plate 41 is evenly arranged around the inner wall of the through hole 21, and the inner wall of the through hole 21 has a slot for the clamping plate 41 to be inserted. One end of the push rod 42 is connected to the clamping plate 41, and the other end passes through the top cover 2. The top cover 2 has a circular hole 22 through which the push rod 42 can pass, and the push rod 42 can slide relative to the circular hole 22. The control sleeve 43 is sleeved on the outside of the top cover 2, and the axis of the control sleeve 43 coincides with the axis of the through hole 21. The outer wall of the top cover 2 has a mounting groove 23 that mates with the control sleeve 43. The reset member 49 is a spring, which is sleeved on... One end of the push rod 42 is fixed to the push rod 42, and the other end is fixed to the side wall of the mounting groove 23. The push block 44 is evenly fixed on the inner wall of the control sleeve 43, corresponding to the push rod 42. The push block 44 has an arc-shaped curved surface 441. The end of the push rod 42 abuts against the arc-shaped curved surface 441. Before the tube is inserted, the clamping plate 41 is inserted into the slot to avoid interfering with the insertion of the tube. After the tube is inserted, the push block 44 is rotated relative to the through hole 21 by rotating the control sleeve 43. Under the guidance of the arc-shaped curved surface 441 of the push block 44, the clamping plate 41 can be pushed out of the slot, thereby clamping the tube.
[0039] As a preferred embodiment, a reset element 49 is sleeved on the top rod 42. The reset element 49 is made of spring and is sleeved on the top rod 42. One end of the spring is fixed on the top rod 42 and the other end is fixed on the side wall of the mounting groove 23. When the reset element 49 is pulled, the clamping plate 41 will be inserted into the slot, so as to prevent the clamping plate 41 from sliding out of the slot and interfering with the insertion of the tube.
[0040] As a preferred embodiment, the clamping mechanism also includes a connecting sleeve 45 and an elastic element 46. The connecting sleeve 45 is fixed on the clamping plate 41. The elastic element 46 is a spring, with one end fixed to the clamping plate 41 and the other end fixed to the push rod 42. One end of the push rod 42 extends into the connecting sleeve 45, ensuring the adjustability and uniformity of the clamping force and avoiding deformation or damage to the tube due to excessive clamping.
[0041] As a preferred embodiment, the top cover 2 has an insertion hole 24 for insertion into the top of the tube body 1, and the outer wall of the tube body 1 has multiple elastic sealing protrusions 25, and the inner wall of the insertion hole 24 has a sealing groove that mates with the elastic sealing protrusions 25.
[0042] As a preferred embodiment, a limiting plate 47 is fixedly provided on the outer wall of the control sleeve 43, and the limiting plate 47 is in contact with the outer wall of the top cover 2.
[0043] As a preferred embodiment, the end of the push rod 42 is provided with a ball bearing 48. The ball bearing 48 at the end of the push rod 42 replaces sliding friction with rolling friction, which significantly reduces the friction between the push rod 42 and the arc surface of the push block 44, making the rotation of the control sleeve 43 easier and smoother.
[0044] In other embodiments, the bottom of the tube body 1 is detachably provided with an elastic sleeve 51, which has a groove for the bottom of the tube body 1 to be inserted into; a support plate 52 is fixedly provided at the bottom of the elastic sleeve 51, so when test tubes need to be placed, the bottom end of the tube body 1 can be inserted into the groove. The detachable connection design between the elastic sleeve 51 and the bottom of the tube body 1 allows for quick engagement through the groove, simplifying the assembly steps. The addition of the bottom support plate 52 enhances the upright stability of the test tubes and prevents them from tipping over; one side of the support plate 52 is provided with an insertion plate 53, and the other side is provided with an insertion groove 54, into which the insertion plate 53 can be inserted; an elastic protrusion 55 is fixedly provided on the side wall of the insertion plate 53, and the insertion groove 54 is provided with a limiting groove 56 that cooperates with the elastic protrusion 55. When multiple test tubes need to be placed, the insertion plates 53 on adjacent support plates 52 can be inserted into the insertion groove 54, and the elastic protrusion 55 can be inserted into the limiting groove 56.
[0045] In other embodiments, an anti-slip sleeve 6 is provided on the tube body 1. The anti-slip sleeve 6 increases the coefficient of friction of the outer wall of the tube body 1, making the test tube more stable when the user holds it and preventing accidental drop due to slipping.
[0046] In other embodiments, a plurality of anti-slip protrusions 7 are evenly fixed on the limiting plate 47. The anti-slip protrusions 7 on the limiting plate 47 increase the friction when the user rotates the control sleeve 43, making the operation more precise and effortless. This design is particularly suitable for operation while wearing gloves or in humid environments, reducing the risk of misoperation and improving the user experience.
[0047] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
