Detailed implementation manners

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0026] As Figures 1-4 shown, the embodiment of the present utility model provides a multi - specification centrifuge tube fixing device, including a fixing plate 1 and a movable plate 2. There are at least two fixing plates 1, and the fixing plates 1 are arranged in parallel. The fixing plates 1 are connected by a vertical connecting member 3; an installation space 12 for installing the centrifuge tube is formed between two adjacent fixing plates 1. A movable plate 2 is arranged in the installation space 12. A plurality of installation holes 21 are arranged on the movable plate 2. The centrifuge tube can be inserted and placed into the installation holes 21. The movable plate 2 is adjustably installed on the vertical connecting member 3, and an elastic support member 4 for supporting the movable plate 2 is arranged on the vertical connecting member 3.

[0027] Specifically, the fixing plate 1 is a horizontal plate. There can be two, three or more fixing plates 1, and the fixing plates 1 are arranged in parallel in sequence. The distance between the fixing plates 1 is set as required, that is, the distance between two fixing plates 1 can be the same or different. The fixing plates 1 are connected by a vertical connecting member 3. The vertical connecting member 3 can be a fixing rod 31, and the fixing plate 1 and the fixing rod 31 are fixedly connected. The fixing rod 31 can be two or four. An installation space 12 for installing centrifuge tubes is formed between the fixing plates 1. For example, if there are three fixing plates 1, from top to bottom, they are the first fixing plate 1, the second fixing plate 1 and the third fixing plate 1. An installation space 12 is formed between the first fixing plate 1 and the second fixing plate 1, and an installation space 12 is also formed between the second fixing plate 1 and the third fixing plate 1.

[0028] In this embodiment, a movable plate 2 is provided in each installation space 12. The movable plate 2 is arranged parallel to the fixing plate 1. A plurality of installation holes 21 are provided on the movable plate 2. The plurality of installation holes 21 are arranged at intervals along the movable plate 2 in sequence. The number of installation holes 21 can meet the requirement of batch processing of centrifuge tubes at one time. The aperture of the installation hole 21 corresponds to the size of the centrifuge tube, that is, each centrifuge tube can be placed in the installation hole 21 for fixing. The movable plate 2 is adjustably installed on the fixing rod 31, that is, the movable plate 2 can move up and down along the fixing rod 31, so as to adjust the distance between the movable plate 2 and the fixing plate 1, and make the installation distance between the movable plate 2 and the fixing plate 1 at its bottom consistent with the centrifuge tube. For example, if the length of the centrifuge tube is small, the movable plate 2 is adjusted downward to make the installation distance between the movable plate 2 and the fixing plate 1 at its bottom smaller. On the contrary, when the length of the centrifuge tube is large, the movable plate 2 is adjusted upward to make the installation distance between the movable plate 2 and the fixing plate 1 at its bottom larger. At the same time, an elastic support member 4 is provided on the fixing rod 31, and the elastic support member 4 can elastically support the movable plate 2.

[0029] An embodiment of the utility model provides a multi-specification centrifuge tube fixing device, which includes a fixing plate 1 and a movable plate 2. The fixing plates 1 are connected by a vertical connecting member 3. An installation space 12 for installing centrifuge tubes is formed between two adjacent fixing plates 1. A movable plate 2 is provided in the installation space 12. The movable plate 2 is adjustably installed on the vertical connecting member 3. An elastic support member 4 for supporting the movable plate 2 is provided on the vertical connecting member 3. In this way, during use, the height of the movable rod can be adjusted as required, so that the installation distance between the movable plate 2 and the fixing plate 1 at its bottom corresponds to the length of the centrifuge tube, which is convenient for placing and fixing centrifuge tubes of different sizes. And when the specifications of the centrifuge tubes are different, the heights of the movable plates 2 in each installation space 12 can be different, so as to facilitate the fixing of centrifuge tubes of different specifications.

[0030] In this embodiment, preferably, moving holes 22 are provided on opposite sides of the moving plate 2. The moving holes 22 are sleeved on the fixed rods 31. The number of the moving holes 22 is consistent with the number of the fixed rods 31. The aperture of the moving holes 22 is larger than the size of the fixed rods 31. In this way, the moving plate 2 is adjustably mounted on the fixed rods 31, and the moving plate 2 can move up and down along the axial direction of the fixed rods 31.

[0031] In this embodiment, preferably, limiting grooves 11 are provided on the fixed plate 1. The limiting grooves 11 are arranged in one-to-one correspondence with the mounting holes 21. The bottom of the centrifuge tube can be limited in the limiting grooves 11. The limiting grooves 11 are circular grooves. The number of the circular grooves is consistent with the number of the mounting holes 21. Elastic gaskets can also be provided in the limiting grooves 11. In this way, during use, the centrifuge tube is inserted into the mounting holes 21, the bottom of the centrifuge tube is located in the limiting grooves 11, and the upper part of the centrifuge tube is limited in the mounting holes 21.

[0032] In this embodiment, preferably, the elastic support member 4 includes an upper support member 41, a lower adjusting member 42, and a spring member 43 disposed between the upper support member 41 and the lower adjusting member 42. The upper support member 41 is fixedly mounted on the top of the spring member 43, and the lower adjusting member 42 is fixedly mounted on the bottom of the spring member 43. The spring member 43 is sleeved on the fixed rods 31. The lower adjusting member 42 includes an adjusting nut 421. A threaded portion 32 is provided at the lower end of the fixed rod 31. The adjusting nut 421 is rotatably mounted on the threaded portion 32. The upper support member 41 is connected to the bottom of the moving plate 2. In this way, during use, the adjusting nut 421 can rotate along the fixed rod 31, so as to adjust the height of the adjusting nut 421, and realize the adjustment of the mounting distance between the moving plate 2 and the fixed plate 1 at its bottom. In this way, the elastic support member 4 has two effects: First, support the adjusted moving plate 2 so that the moving plate 2 is limited at the adjusted height; Second, during the operation, the moving plate 2 can be pressed down by hand, and the moving plate 2 presses against the spring member 43. In this way, the moving plate 2 can have a press-adjustable movement range along the axial direction of the fixed rod 31, which is convenient for the placement and removal of the centrifuge tube.

[0033] In this embodiment, preferably, the upper support member 41 includes an annular support member 411 and an annular connecting member 412. The annular support member 411 is fixedly installed at the bottom of the movable plate 2, and the annular connecting member 412 is fixedly installed at the top of the spring member 43. A rotating connecting plate is provided at the top of the annular connecting member 412, and an annular cavity 413 is provided at the bottom of the annular support member 411. The rotating connecting plate is rotatably installed in the annular cavity 413. The annular connecting member 412 and the annular support member 411 are coaxially installed with the movement hole 22, and the annular connecting member 412, the annular support member 411, and the movable plate 2 can move up and down along the fixed rod 31. An annular limiting groove is provided on the inner wall of the annular cavity 413, and an annular side edge is provided on the annular connecting plate. The annular side edge is rotatably limited in the annular limiting groove. Thus, during use, when the adjusting nut 421 rotates on the threaded portion 32, the spring member 43 and the annular connecting member 412 both rotate synchronously with the adjusting nut 421. Since the annular support member 411 is rotatably connected to the annular connecting member 412, at this time, the annular support member 411 does not rotate, but in the axial direction of the fixed rod 31, the annular connecting member 412 restricts the annular support member 411, so that the annular support member 411 cannot move up and down freely. That is, when the adjusting nut 421 rotates downward or upward along the threaded portion 32 of the fixed rod 31, it can drive the annular support member 411 and the movable plate 2 to move upward or downward along the axis of the fixed rod 31.

[0034] In this embodiment, preferably, an annular member 422 is provided at the bottom of the adjusting nut 421. An elastic piece 423 is provided on the inner wall of the annular member 422. A locking thread is provided at one end of the elastic piece 423 close to the fixed rod 31, and the locking thread corresponds to the threaded portion 32. A rotating screw hole is provided on the side wall of the annular member 422, and a locking rotating bolt 424 is provided in the rotating screw hole. The elastic piece 423 is an arc-shaped iron sheet. The rotating screw hole is correspondingly provided with the elastic piece 423. One end of the locking rotating bolt 424 is located inside the annular member 422 and abuts against the elastic piece 423, and the other end of the locking rotating bolt 424 extends out of the rotating screw hole to form a rotating operation structure. In the normal state of the elastic piece 423, the distance between the two elastic pieces 423 is greater than the radial dimension of the fixed rod 31. Thus, the annular member 422 can move up and down along the fixed rod 31. When the adjusting nut 421 rotates to a suitable position, the rotating operation structure of the locking rotating bolt 424 is operated, so that the locking rotating bolt 424 moves inward, and the locking rotating bolt 424 presses against the elastic piece 423 to cause it to deform until the elastic piece 423 abuts against and contacts the fixed rod 31. At this time, the locking thread is locked and fixed with the threaded portion 32. On the contrary, if the locking rotating bolt 424 is rotated in the reverse direction, the pressing force of the locking rotating bolt 424 on the elastic piece 423 disappears, and the elastic piece 423 can return to its initial state.

[0035] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
