[0002] Laboratory PE tubes are one of the laboratory consumables, and their main function is to be used for liquid transmission, drug delivery, and various other experimental operations during experiments. The importance of laboratory PE tubes not only lies in their wide application range but also in a series of advantages brought by their specific materials, such as chemical stability, physical durability, and biocompatibility, etc.

[0003] When using existing laboratory PE tubes, it is necessary to open the caps one by one, which increases the experimental preparation time. In high-throughput experiments, such as genomics research or large-scale nucleic acid detection, the inability to open the caps uniformly will greatly limit the sample processing speed and quantity, affecting the overall experimental progress. Therefore, it is necessary to provide an opening device for laboratory PE tubes that can open the caps of multiple PE tubes. Content of the Utility Model

[0004] The purpose of the utility model is to provide an opening device for laboratory PE tubes to solve the problem proposed in the above background technique that when using existing laboratory PE tubes, it is necessary to open the caps one by one, which increases the experimental preparation time. In high-throughput experiments, such as genomics research or large-scale nucleic acid detection, the inability to open the caps uniformly will greatly limit the sample processing speed and quantity, affecting the overall experimental progress.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is an opening device for laboratory PE tubes, including:

[0007] A clamping mechanism, the clamping mechanism includes a bracket;

[0008] An opening mechanism, the opening mechanism includes a meshing sleeve fixedly connected to the inner wall of the middle of the bracket. The inner wall of the meshing sleeve is threadedly connected with a threaded rod. The end of the threaded rod is fixedly connected to the outer wall of the circumferential surface. The outer wall of the end of the connecting sleeve is rotatably connected to a second annular shaft. The outer wall of the circumferential surface of the second annular shaft is equidistantly fixedly connected with a pushing frame. The outer wall of the meshing sleeve is fixedly connected with a fixed sleeve. The outer wall of the circumferential surface of the fixed sleeve is equidistantly provided with movable grooves. The inner wall of the movable groove is rotatably connected with a spherical shaft. One end of the spherical shaft close to the threaded rod is fixedly connected with a pressing rod.

[0009] Furthermore, the bracket is equidistantly penetrated with installation grooves around the circumference. The inner walls of the circumferences of the installation grooves are symmetrically fixedly connected with connecting springs. The ends of the connecting springs are fixedly connected with clamping plates;

[0010] Further, a handle is fixedly connected to the outer wall of the top of the threaded rod. A first annular groove is formed in the outer wall of the bottom of the connecting sleeve, and the inner diameter of the fixed sleeve is larger than the outer diameter of the threaded rod;

[0011] Wherein, a second annular shaft is rotatably connected to the inner wall of the first annular groove;

[0012] Further, a second sleeve is fixedly connected to the outer wall of the ball shaft, and a second telescopic rod is threadedly connected to the inner wall of the second sleeve;

[0016] 1. In the present utility model, after inserting the PE pipe into the installation groove and the connecting spring rebounds to clamp the PE pipe with the clamping plate, manually rotate the threaded rod to move up and down in the meshing sleeve. The threaded rod drives the connecting sleeve to approach the lid of the PE pipe. When the connecting sleeve moves to make the pushing frame enter the fixed sleeve, the pushing frame pushes the pressure rod. The connecting sleeve continues to move and drives the ball shaft to rotate in the moving groove through the pushing frame. The ball shaft adjusts the angle of the second sleeve, and the second telescopic rod can be rotated in the second sleeve to adjust the length of the second telescopic rod. The second telescopic rod is driven by the second sleeve to contact the bottom outer wall of the lid body.

[0030] A clamping mechanism 1, and the clamping mechanism 1 includes a bracket 101;

[0031] The bracket 101 is equidistantly penetrated by installation grooves 102 around the circumference. Symmetrically fixed to the inner wall of the circumference of the installation grooves 102 are connecting springs 103, and the ends of the connecting springs 103 are fixedly connected with clamping plates 104;

[0032] The clamping plates 104 clamp the PE tube by the rebound of the connecting springs 103;

[0033] An opening mechanism 3, and the opening mechanism 3 includes an engaging sleeve 301 fixedly connected to the inner wall of the middle of the bracket 101. Threadedly connected to the inner wall of the engaging sleeve 301 is a threaded rod 302. Fixedly connected to the outer wall of the circumference of the end of the threaded rod 302 is a connecting sleeve 303. Rotatably connected to the outer wall of the end of the connecting sleeve 303 is a second annular shaft 304. Equally spaced and fixedly connected to the outer wall of the circumference of the second annular shaft 304 are push frames 305. Fixedly connected to the outer wall of the engaging sleeve 301 is a fixed sleeve 306. Equally spaced and provided on the outer wall of the circumference of the fixed sleeve 306 are movable grooves 307.

Fixedly connected to the outer wall of one end of the spherical shaft 308 close to the threaded rod 302 is a pressure rod 311;

[0034] Rotating the threaded rod 302 causes the threaded rod 302 to move up and down through the engaging sleeve 301, supports the second annular shaft 304 through the connecting sleeve 303, and rotatably supports the push frames 305 through the second annular shaft 304;

[0035] Fixedly connected to the outer wall of the top of the threaded rod 302 is a handle. An annular groove is provided on the outer wall of the bottom of the connecting sleeve 303. The inner diameter of the fixed sleeve 306 is larger than the outer diameter of the threaded rod 302;

[0038] The outer wall of the ball shaft 308 is fixedly connected with a second sleeve 309, and the inner wall of the second sleeve 309 is threadedly connected with a second telescopic rod 310;

[0039] Drive the ball shaft 308 to rotate through the push frame 305, drive the second sleeve 309 to rotate through the ball shaft 308, and rotate the second telescopic rod 310 in the second sleeve 309 to adjust the length of the second telescopic rod 310, and open the lid by continuously adjusting the angle of the second telescopic rod 310;

[0040] Working principle: Insert the PE pipe into the installation groove 102. After the connecting spring 103 rebounds to clamp the PE pipe with the clamping plate 104, manually rotate the threaded rod 302 to move up and down in the meshing sleeve 301. The threaded rod 302 drives the connecting sleeve 303 close to the lid of the PE pipe.
