Description

Technical Field

[0001] The utility model relates to the technical field of cell culture utensils, in particular to a clamping tray for cell cryopreservation tubes. Background Technique

[0002] During the cell culture process, cell cryopreservation tubes are consumables frequently used in cell experiments. Cell cryopreservation tubes often move back and forth between various operating tables. Generally, the experimenter takes good protective measures and holds the cell cryopreservation tubes to perform various operations. Generally, the number of cell cryopreservation tubes held by hand is limited, and it is extremely easy to drop during the holding process. Content of the Utility Model

[0003] The purpose of the utility model is to provide a clamping tray for cell cryopreservation tubes to overcome the above-mentioned defects in the prior art.

[0004] According to a clamping tray for cell cryopreservation tubes of the utility model, it includes a clamping tray. A handle is fixedly arranged on the upper end surface of the clamping tray. Uniformly distributed tube openings are arranged on the clamping tray. Fixed sleeves are fixedly arranged on the upper end surface of the clamping tray and at each tube opening. A test tube is arranged at the tube opening. A magnet ring is fixedly arranged on the fixed sleeve. The upper end part of the fixed sleeve is provided with a downwardly recessed conical surface. A placement tray is abutted on the fixed sleeve. Circumferentially uniformly distributed sliding cavities are arranged in the placement tray. Sliders are slidably connected to the sliding cavities. A return spring is connected between the slider and the side wall of the sliding cavity. The upper end of the slider is rotatably connected with a clamping block. An elastic pad is arranged on the inner end surface of the clamping block. Circumferentially uniformly distributed buffer plates are fixedly arranged on the upper end surface of the placement tray. The elastic pads and the buffer plates are staggered and have the same number. The elastic pads are arranged in a U-shape on the inner end and two side end surfaces of the clamping block. A circular through cavity is arranged at the sliding cavity to the magnet ring. A through hole is arranged in the middle part of the fixed sleeve. The radius of the through hole is the same as that of the tube opening and larger than the radius of the test tube.

[0005] The beneficial effects of the utility model are:

[0006] A fixed sleeve is fixedly connected at the tube opening. The slider is attracted by the magnet ring on the fixed sleeve, so that the clamping blocks approach each other to clamp the test tube, maintaining the stability of the test tube at the clamping tray, and thus realizing the transportation and carrying of multiple test tubes through the clamping tray.

[0007] Through the downwardly recessed conical surface at the upper end of the fixed sleeve, when the user places the placement tray, the operation requirements for the user can be reduced, the placement tray can be automatically centered, and it is convenient for the user to perform batch operations.

[0008] The elastic pad is in contact with the buffer plate and the test tube for buffering, and the impact force when the clamp moves is transmitted to the test tube and the buffer plate. The elastic pad can buffer and reduce the impact force on the test tube, preventing the test tube from being damaged when the clamp automatically clamps the test tube.

[0017] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time:

[0019] Embodiment 1:

[0020] Reference Figure 1-Figure 6 Figure 1-Figure 6 , a cell cryopreservation tube clamping tray according to an embodiment of the present utility model, includes a clamping tray 10. A handle 12 is fixedly provided on the upper end surface of the clamping tray 10. Uniformly distributed tube openings 11 are formed on the clamping tray 10. Fixed sleeves 14 are fixedly provided on the upper end surface of the clamping tray 10 and at each tube opening 11. A test tube 13 is provided at the tube opening 11. A magnet ring 16 is fixedly provided on the fixed sleeve 14. The upper part of the fixed sleeve 14 is provided with a tapered surface 15 that is recessed downward. A placement tray 18 is abutted on the fixed sleeve 14. A circumferentially uniformly distributed sliding cavity 17 is formed in the placement tray 18. A slider 19 is slidably connected to the sliding cavity 17. A return spring 23 is connected between the slider 19 and the side wall of the sliding cavity 17. The upper end of the slider 19 is rotatably connected to a clamping block 20. An elastic pad 21 is provided on the inner end surface of the clamping block 20. Buffer plates 22 that are circumferentially uniformly distributed are fixedly provided on the upper end surface of the placement tray 18. The elastic pads 21 and the buffer plates 22 are staggered and have the same number. The elastic pads 21 are arranged in a U-shape on the inner end and two side surfaces of the clamping block 20. A circular through cavity is provided at the sliding cavity 17 to the magnet ring 16. A through hole is formed in the middle part of the fixed sleeve 14. The through hole has the same radius as that at the tube opening 11 and is larger than the radius of the test tube 13;

[0021] The user holds the handle 12 and places the test tube 13 at the uniformly distributed tube openings 11. For the fixed sleeve 14 where the test tube 13 is provided, the user places the placement tray 18 on the fixed sleeve 14. Under the abutment of the tapered surface 15, the placement tray 18 moves downward from top to bottom. The placement tray 18 is centered under the abutment of the tapered surface 15, so that a part of the inner peripheral surface of the placement tray 18 abuts on the magnet ring 16. The magnet ring 16 emits magnetic force to the circumferential side. Under the action of the magnetic force, the slider 19 connected to the return spring 23 is attracted through the sliding cavity 17, so that the circumferentially uniformly distributed sliders 19 slide along the sliding cavity 17 towards the magnet ring 16 end, thereby driving the clamping block 20 connected to the upper end of the slider 19 to move, so that the circumferentially arranged clamping blocks 20 approach the test tube 13. The elastic pads 21 on the clamping blocks 20 abut on the circumferentially uniformly distributed buffer plates 22 and the test tube 13 for buffering. The clamping force is provided by the clamping blocks 20, and the test tube 13 is fixedly arranged on the tube opening 11. The user can freely move the test tube 13 on the clamping tray 10 by lifting the handle 12;

[0022] The user holds the circumferentially distributed clamping blocks 20 and removes the test tube 13 clamped by the clamping blocks 20 from the clamping tray 10. After placing the test tube 13 at the corresponding position, the user releases the clamping blocks 20. When the clamping blocks 20 lose the magnetic attraction, under the spring action of the return spring 23, the clamping blocks 20 are pushed to move towards the outer end direction, so that the clamping blocks 20 are disengaged from the clamping of the test tube 13. The user removes and partially stores the placement tray 18 from bottom to top.

[0023] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
