Detailed Description
The present invention will be described in detail with reference to the accompanying drawings, as shown in fig. 1, a sample storage tube mainly includes the following two parts: the tube body 1 and the tube cover 2 which is sleeved on the tube body 1, wherein the tube body 1 is made of corrosion-resistant plastics (not only plastics, but also other hard materials with excellent characteristics), the tube cover 2 is made of rubber, and the ratio of the overall height of the tube cover 2 to the overall height of the tube body 1 is 1:5, so that freeze-dried samples such as freeze-dried nucleic acid samples can be safely put into the tube body 1 for sealed storage, the sealing performance of a storage tube cannot be influenced when the freeze-dried samples are taken and put, and the interior of the storage tube cannot be polluted.
As shown in fig. 3, we have specially designed the tube cap 2, the tube cap 2 mainly includes a cap body 21, and we have designed a double-layer seal for the cap body 21, so an outer baffle ring 22 and an inner baffle ring 23 are disposed at the bottom of the cap body 21, the diameter of the inner baffle ring is smaller than that of the outer baffle ring 22, and the overall height of the inner baffle ring 23 is greater than that of the outer baffle ring 22, and the outer diameter of the inner baffle ring 23 is consistent with the inner diameter of the tube opening of the tube body 1, so that when the inner baffle ring 23 is inserted into the tube body 1 from the tube opening of the tube body 1, the inner baffle ring 23 can be tightly attached to the inner wall of the tube body 1, thereby playing a role of sealing.
Keep off ring 22 and interior fender ring 23 outward and all with lid 21 body coupling, in keep off ring 23 and keep off ring 22 outward and locate the bottom of lid 21, can form a gomphosis cavity 26 that is used for holding body 1 orificial jointly with lid 21, when overlapping tube cap 2 on body 1, the mouth of pipe department of body 1 can be embedded into in the gomphosis cavity 26 of lid 21 bottom to interference fit plays double-deck sealed effect to body 1 inside and outside.
Meanwhile, as shown in fig. 2, at least one first sealing protrusion 12 is disposed on the outer side of the pipe orifice of the pipe body 1 (in this embodiment, one first sealing protrusion 12 is disposed, which is not limited to one, and may be multiple), and the outer baffle ring at the bottom of the cover body 21 is matched with the first sealing protrusion 12 to enhance the sealing on the outer side of the pipe body 1; at least one second sealing bulge 13 is arranged on the inner side of the pipe orifice of the pipe body 1, so that the inner baffle ring at the bottom of the cover body 21 can be matched with the second sealing bulge 13 to strengthen the sealing on the inner side of the pipe body 1.
If the number of the second sealing protrusions 13 is greater than or equal to 2 (two second sealing protrusions are provided in this embodiment, actually, the number is not limited to 2, or more than 2), the inner diameter of the second sealing ring protrusion from top to bottom along the tube body 1 will gradually decrease, so the design is designed to have a slight deformation when the tube cap 2 is sleeved on the tube body 1, and the inner baffle ring 23 will extend into the inner side of the tube body 1, because the whole tube cap 2 is made of rubber, the whole tube cap 2 has certain elasticity, so when the inner baffle ring 23 is matched with the second sealing protrusion 13 on the inner side of the tube body 1, two seals are performed on the inner side of the tube body 1, and therefore the inner diameter of the second sealing protrusion 13 decreases downward, that is, when the inner baffle ring 23 extends into the inner side of the tube body 1, the inner diameter of the second sealing protrusion 13 limits, and extends downward, the inner pressure from the second sealing protrusion 13 is increased, the inner baffle ring receives the inner and outer pressure, so that the tightness between the inner baffle ring and the second sealing protrusion 13 can be increased, and the inner baffle ring and the two sides of the tube body 1 can be sealed together with the outer baffle ring.
In order to detach the tube cap 2 conveniently, the top of the cap body 21 is further provided with a quick-release structure 24, the quick-release structure 24 is composed of two parts, namely a ring sleeve 241 and an outer ring 242 which is arranged at the top of the ring sleeve 241 and integrally connected with the ring sleeve 241 and extends outwards along the radial direction of the ring sleeve 241, when a machine clamping jaw extends into a gap at the top of the tube cap 2, the quick-release structure 24 can be fastened with the quick-release structure 24, a downward force can be applied to the middle of the tube cap 2, the tube cap 2 is made to be sunken inwards, the outer blocking ring 22 is driven to tilt, the inner blocking ring 23 can be contracted towards the middle, and thus the machine clamping jaw can pull the tube cap 2 upwards, so that the tube cap 2 can be detached automatically, and the detection efficiency of a sample is improved.
In order to facilitate taking and placing of a sample, a circular recess is formed in the middle of the cover body 21, the diameter of the circular recess is consistent with the inner diameter of the ring sleeve, and the circular recess is designed to enable a circular thin-wall layer to be formed in the middle of the cover body 21 and penetrate through the thin-wall layer through a sharp tool, so that the sample can be taken and placed (the principle is basically the same as that of liquid taking through an injector).
The bottom of silo 11 is 3 to the whole high ratio of distance between the bottom of body 1 and body 1 (if the whole height of body 1 is 5cm, then the bottom of silo 11 is 1.5cm to the distance between the body 1 bottom), and the purpose of design just so is the influence of the temperature of minimize body 1 bottom to the sample in the silo 11, and through this storage tube, the sample that can be fine is preserved, can effectively reduce the risk that sample and outside air contacted moreover.
Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical staff probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
