[0028] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0029] Example 1:

[0030] A specimen tube encapsulator, such as Figure 1 It includes a closing unit 8, which includes: a housing 7, a spring 6, a traction assembly 2, a pressure module 4, and a loading button 1.

[0031] The outer casing 7 has a storage space inside for accommodating several covers 13. The covers 13 can be plug-type covers or ordinary snap-on covers, etc. The bottom of the storage space has an opening, and the inner wall of the storage space is provided with mating teeth 5, which are arranged in the height direction.

[0032] The outer casing 7 can be partially or entirely made of transparent plastic material, such as PVC, to make it easy to determine the remaining quantity of the cover.

[0033] The spring 6 can be made of metal and can produce elastic deformation. It is set at the bottom of the storage space to block the cover. At least two sets of spring 6 are set on both sides of the storage space.

[0034] The traction component 2 includes a traction rope connected to the spring piece 6. The traction component 2 can actively control the deformation of the spring piece 6. After bending the spring piece 6 outward, the cover 13 can be loaded into the storage space.

[0035] The pressure module 4 is installed in the storage space, such as Figure 2 The pressure module 4 includes a connecting frame 44, a pressure body 42, a movable tooth 41, and a connecting rod 43. The connecting frame 44 is connected to the top of the storage space in the outer shell 7 through a telescopic rod 3. The telescopic rod 3 serves to support and guide the connecting frame 44. The movable tooth 41 has an overall L-shaped structure, with one end hinged to the connecting frame 44. The pressure body 42 includes a disc-shaped structure with its bottom in contact with the cover and a support structure connected to the disc-shaped structure. The movable tooth 41 is also hinged to the support structure of the pressure body 42 through the connecting rod 43. The movable tooth 41 can contact and engage with the mating tooth 5 to achieve a position holding effect.

[0036] When the lid is closed, the lid generates an upward reaction force, the movable tooth 41 contacts the mating tooth 5, restricting the upward movement of the pressure module 4, so that the lid can close on the specimen tube when pressure is applied. After the lid moves downward, the pressure body 42 moves downward, and the movable tooth 41 retracts through the connecting rod 43, and the pressure module 4 descends until the pressure body 42 contacts the lid.

[0037] like Figure 3 The loading button 1 is used to control the traction assembly 2. The loading button 1 includes a pressing body 101, a return spring 102, and a traction connecting body 103 disposed on the pressing body 101. The pressing body 101 is mounted on the housing 7 and connected to the return spring 102. The traction connecting body 103 is connected to the traction assembly 2. The traction rope in the traction assembly 2 is connected to the spring piece 6 through the redirecting wheel. When the pressing body 101 is pressed down, the spring piece is deformed by the traction rope.

[0038] Preferably, the loading button 1 further includes a guide post 104, which slides in conjunction with the inner hole in the pressing body 101 to guide and stabilize the pressing body 101.

[0039] Procedure for closing the lid:

[0040] 1) The outer shell 7 is set as a two-piece assembly that can be opened. After opening the outer shell 7, manually move the pressure module 4 inside to the top of the storage space, and then assemble the outer shell 7.

[0041] 2) Press down on the pressing body 101, and the traction rope will pull the spring piece to deform it. After bending the spring piece 6 outward, the cover 13 will be filled into the storage space.

[0042] 3) After filling, when closing the cap, hold the outer shell 7 and press down to insert the cap into the specimen tube or snap the cap onto the specimen tube. At this time, an upward reaction force is generated, and the movable tooth 41 contacts the mating tooth 5, restricting the upward movement of the pressure module 4, thereby applying pressure to close the cap onto the specimen tube. After closing, lift the closing unit 8. The cap 13 remains on the tube due to the friction between it and the tube (the spring returns to its original shape after the corresponding deformation). If the cap is not closed tightly, the cap 13 will not remain on the tube and the operation needs to be repeated.

[0043] 4) After the cover moves downward, the pressing body 42 moves downward, and the movable tooth 41 retracts through the connecting rod 43, and the pressing module 4 descends until the pressing body 42 contacts the cover, providing pressure for the next closing operation.

[0044] The above structure allows for multiple capping operations after a single filling, which improves efficiency compared to the traditional manual cap removal and closing method, reduces the labor intensity of operators, and ensures the stability of the cap.

[0045] Example 2:

[0046] Unlike in Embodiment 1, in this embodiment, it is not necessary to open or close the outer shell 7 to reset the pressing module 4.

[0047] Specifically, the mating teeth 5 in the outer shell 7 are arranged in strips on both sides. After the movable teeth 41 rotates at a certain angle and disengages from the mating teeth 5, the pressing module 4 can move freely in the outer shell. The guide post 104 is rotatably mounted on the outer shell 7. The telescopic rod 3 is connected to the guide post 104. The pressing body 101 and the guide post 104 are in sliding fit. If a spline structure is adopted, the pressing body 101 is rotatably mounted on the outer shell 7. By rotating the pressing body 101 (e.g., 90°), the pressing module 4 can be driven to rotate, causing the movable teeth 41 to disengage from the mating teeth 5. Then, the outer shell 7 is inverted, causing the pressing module 4 to move to the top position of the storage space. Then, the pressing body 101 is rotated to rotate the pressing module 4 back to the initial position, so that the movable teeth 41 engage with the mating teeth 5. At this time, the pressing body 101 can be pressed to fill the space.

[0048] Example 3:

[0049] Based on Embodiment 1 or 2, this embodiment adds a batch operation unit, which can achieve the effect of batch sealing and capping.

[0050] like Figure 6 , Figure 7The batch operation unit includes a batch cap frame 12 and a pressing handle 11. Several cap closing units 8 can be installed on the batch cap frame 12. The pressing handle 11 is movably installed on the batch cap frame 12. The batch cap frame 12 is provided with a sliding groove. The pressing handle 11 is installed in the sliding groove. A spring is provided in the sliding groove to reset the pressing handle 11. The pressing handle 11 is used to press the pressing body 101 in batches.

[0051] The batch cap holder 12 is provided with holes for installing the cap unit 8. The outer shell 7 can be installed at the holes by means of threaded fit, interference fit or slot fit.

[0052] Install the capping unit 8 on the batch cap frame 12, operate the pressing handle 11 to press the pressing body 101 in batches, and manual batch filling can be performed. By holding the batch cap frame 12 and pressing it, the batch capping effect can be achieved.

[0053] Furthermore, the specimen tube sealer also includes a cap holder, which includes several cap placement areas 9 for batch capping. Each cap placement area 9 is formed by three rods and is located on the base plate 10. After pressing the handle 11, the capping unit 8 is placed on the cap placement area 9. The positions of the rods and the spring clips are offset. After the cap placement area 9 enters the bottom of the storage space, the handle 11 is released, and the cap holder is pulled out to complete the batch filling.

[0054] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
