Description

Technical Field

[0001] This utility model relates to the field of EP pipe rack technology, and in particular to a multi-specification adjustable EP pipe rack. Background Technology

[0002] EP tubes are small centrifuge tubes, also known as microcentrifuge tubes, commonly used in biochemistry and molecular biology laboratories. They are used with microcentrifuges for separation and centrifugation. EP tubes typically have a conical bottom, making them unsuitable for direct placement. Therefore, EP tube racks are used for storage. EP tube racks are not limited to storing EP tubes; in animal cell experiments, EP tubes containing samples are often placed on the racks, and the racks are tilted to observe the internal structure of the tubes. Most existing EP tube racks are rectangular boxes with multiple rows and columns of through-holes for storing EP tubes. Each rack can hold multiple EP tubes.

[0003] However, existing EP tube racks have a relatively limited function. They are usually fixed structures with multiple rows and columns of EP tube holes arranged in parallel, which makes it inconvenient to observe the samples inside the EP tubes. Moreover, most existing EP tube racks have the same hole diameter, and the height of the stored EP tubes is also fixed. They can only store EP tubes of fixed specifications and cannot flexibly adjust the specifications of the EP tube rack according to experimental needs. This leads to inconvenience in experimental operations, especially when it is necessary to frequently change the specifications of EP tubes, resulting in low experimental efficiency. Utility Model Content

[0004] To address the technical problems of existing EP tube racks being inconvenient for observing samples inside EP tubes, unable to flexibly adjust the specifications of EP tube racks according to experimental needs, and having low experimental efficiency, this utility model provides the following technical solution.

[0005] This utility model discloses a multi-specification adjustable EP tube rack, including a base. Several supporting components are connected to the upper part of the base and arranged side by side. Each supporting component includes an adjusting column and a guide column fixedly connected to the base. The adjusting column and the guide column are slidably connected to a lifting sleeve and a guide slide, respectively. The upper ends of the lifting sleeve and the guide slide are connected to tiltable connectors. The connectors are connected to a detachable perforated plate with several tube holes. The upper and lower ends of the tube holes are respectively connected to elastic rings and positioning tubes that match various specifications of EP tubes.

[0006] As a further technical solution, the adjusting column is provided with a number of adjusting holes in the axial direction, and a lifting ring is fixedly connected to the lower end of the lifting sleeve. A locking member extending into the adjusting hole is connected through the lifting ring.

[0007] As a further technical solution, both the lifting sleeve and the guide slide tube are fixedly provided with connecting fixing plates at their upper ends. The connecting component includes two connecting side plates that are hinged and abutted against the connecting fixing plates and a support block located at the upper end of the connecting side plates.

[0008] As a further technical solution, the upper ends of the lifting sleeve and the guide slide are both fixedly provided with connecting fixing plates. The connecting component includes two connecting side plates that abut against the connecting fixing plate and a support block located at the upper end of the connecting side plates. The connecting fixing plate and the two connecting side plates are connected through a screw and a nut located on one side of the screw.

[0009] As a further technical solution, the upper part of the support block is provided with a locking groove, and the lower part of the detachable perforated plate is provided with an insertion block that matches the locking groove.

[0010] As a further technical solution, a lifting rod is fixedly connected between the lifting sleeve and the guide slide.

[0011] The beneficial effects of this utility model are as follows: the supporting component of this utility model can be raised and lowered for adjustment, thereby adjusting the height of the connecting piece and the detachable perforated plate. The detachable perforated plate is a detachable structure, and with the expansion and contraction of the elastic ring, it can accommodate EP tubes of different diameters. This allows for flexible adjustment of the EP tube rack specifications according to experimental needs, improving experimental efficiency. After the connecting piece is connected to the connecting fixing plate, the detachable perforated plate can be manually pushed and pulled to tilt it at a certain angle. Consequently, the EP tube placed inside the detachable perforated plate will tilt at a certain angle, facilitating observation of the sample inside the EP tube by the experimenter and improving experimental convenience.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0014] In the description of this utility model, it should be understood that the terms "upper" and "lower" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0015] like Figure 1 and Figure 2 As shown, this utility model discloses a multi-specification adjustable EP tube rack, including a base 1. The bottom of the base 1 is provided with multiple anti-slip pads 101, which are thin sheets made of rubber or silicone material to ensure stability during experimental operations. Several supporting components 2 are connected side-by-side to the upper part of the base 1. Connectors 3 are connected to the upper ends of the supporting components 2, and detachable perforated plates 4 are connected to the connectors 3. The detachable perforated plates 4 have multiple tube holes 401 for placing EP tubes. In this embodiment, there are two supporting components 2 and two detachable perforated plates 4, each independently holding an EP tube. Of course, there can be more supporting components 2, and thus more detachable perforated plates 4, allowing for the placement of more different experimental types and specifications of EP tubes.

[0016] like Figure 1 and Figure 3As shown, in a preferred embodiment, the support component 2 includes an adjusting column 201 and a guide column 203 fixedly connected to the base 1. The adjusting column 201 and the guide column 203 are slidably connected to a lifting sleeve 202 and a guide slide tube 204, respectively. The lifting sleeve 202 can be raised or lowered relative to the adjusting column 201, and the guide slide tube 204 can be raised or lowered relative to the guide column 203, thereby adjusting the height of the detachable perforated plate 4.

[0017] The adjusting column 201 has several adjusting holes 205 along its axis. These holes can be through holes or threaded holes. A lifting ring 207 is fixedly connected to the lower end of the lifting sleeve 202. A locking member 206, extending into the adjusting hole 205, is connected through the lifting ring 207. The locking member 206 can be a pin matching the through hole or a screw matching the threaded hole. After the height of the detachable orifice plate 4 is adjusted, the locking member 206 can pass through the side wall of the lifting ring 207 and extend into the adjusting hole 205, thus connecting and fixing the adjusting column 201 to the lifting sleeve 202. Therefore, adjusting the height of the detachable orifice plate 4 changes the distance between the pipe hole 401 and the base 1, allowing the pipe hole 401 to accommodate EP pipes of different lengths. For commonly used EP pipes, the height adjustment range of the detachable orifice plate 4 is 3cm-8cm.

[0018] Meanwhile, the upper and lower ends of the tube hole 401 are respectively connected to an elastic ring 402 and a positioning tube 403, which are compatible with various specifications of EP tubes. The inner diameter of the elastic ring 402 is smaller than the inner diameter of the tube hole 401. The elastic ring 402 can elastically clamp common specifications of EP tubes such as 0.5ml, 1ml, 1.5ml and 2ml, so that the tube hole 401 can accommodate a variety of different specifications of EP tubes. The positioning tube 403 is a transparent structure, and its inner diameter is the same as that of the tube hole 401. The positioning tube 403 not only facilitates observation by the experimenter, but also effectively positions the EP tubes in the tube hole 401, preventing them from touching adjacent EP tubes when the elastic ring 402 is not clamped tightly.

[0019] In a preferred embodiment, a lifting rod 208 is fixedly connected between the lifting sleeve 202 and the guide slide tube 204. When the height of the detachable orifice plate 4 needs to be adjusted, the experimenter holds the lifting rod 208 to raise or lower the lifting sleeve 202 and the guide sleeve 204. Then, the locking member 206 passes through the side wall of the lifting ring 207 and extends into the adjustment hole 205 to connect and fix the adjustment column 201 to the lifting sleeve 202.

[0020] like Figure 3 and Figure 4As shown, in a preferred embodiment, the upper ends of the lifting sleeve 202 and the guide slide tube 204 are both connected to the tiltable connector 3. The connector 3 is connected to the detachable orifice plate 4. When the connector 3 is tilted, it can drive the detachable orifice plate 4 to tilt. When tilted, the EP tube can be easily observed by the experimenter.

[0021] In a preferred embodiment, both the lifting sleeve 202 and the guide slide tube 204 are fixedly provided with connecting fixing plates 209 at their upper ends. The connecting member 3 includes two connecting side plates 303 that are hinged and frictionally abutted against the connecting fixing plate 209, and a support block 301 located at the upper end of the connecting side plates 303. The support block 301 is connected to the detachable perforated plate 4. The two connecting side plates 303 are frictionally abutted against the connecting fixing plate 209. When the detachable perforated plate 4 is pushed or pulled forcefully, the detachable perforated plate 4 and the support block 301 tilt and rotate, and the two connecting side plates 303 tilt and rotate relative to the connecting fixing plate 209. At this time, when the detachable perforated plate 4 is released, the frictional abutment between the two connecting side plates 303 and the connecting fixing plate 209 can ensure the tilting stability of the detachable perforated plate 4.

[0022] In a preferred embodiment, both the lifting sleeve 202 and the guide slide tube 204 are fixedly provided with connecting fixing plates 209 at their upper ends. The connecting member 3 includes two connecting side plates 303 that rub against the connecting fixing plate 209 and a support block 301 located at the upper end of the connecting side plates 303. The support block 301 is connected to the detachable perforated plate 4. The connecting fixing plate 209 and the two connecting side plates 303 are connected by a screw 304 and a nut 305 located on one side of the screw 304. When the nut 305 is tightened, the nut 305 moves towards the other end of the screw 304. This allows the two connecting side plates 303 to move relative to each other, clamping the connecting fixing plate 209 tighter and increasing the friction between the three, further ensuring the tilt stability of the detachable perforated plate 4.

[0023] There are multiple ways to detachably connect the support block 301 and the detachable perforated plate 4. In this embodiment, the upper part of the support block 301 is provided with a locking groove 302, and the lower part of the detachable perforated plate 4 is provided with an insertion block 404 that matches the locking groove 302. Thus, the detachable perforated plate 4 and the support block 301 can be detachably connected quickly, and a new detachable perforated plate 4 with a variety of hole diameters can be replaced.

[0024] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
