Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning machine technology, and more particularly to an ultrasonic cleaning machine test tube rack. Background Technology

[0002] Ultrasonic cleaners can not only clean objects, but also disperse experimental reagents. However, when dispersing experimental reagents, existing ultrasonic cleaners typically place a cleaning basket inside the cleaning tank and then directly place the test tubes containing the reagents into the cleaning basket for processing. Since there is no device to stabilize the test tubes in the cleaning basket, the test tubes in the cleaning basket are prone to tilting and tipping over during operation, resulting in reagent loss and contamination of experimental samples. Utility Model Content

[0003] The purpose of this invention is to provide a test tube rack for an ultrasonic cleaner, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an ultrasonic cleaner test tube rack, including a cleaning basket and a placement rack that can be plugged into the cleaning basket. The placement rack is provided with placement holes for placing test tubes, and the bottom of the cleaning basket is provided with support members that provide support for test tubes of different specifications.

[0005] For example, one rack holds 1ml test tubes, and another rack holds 50ml test tubes. Because the racks are removable, both racks can be placed in the cleaning basket; therefore, the test tube rack of this application is suitable for test tubes of different sizes. Simultaneously, the placement holes and supports ensure that the test tubes inside the placement holes stand upright in the cleaning basket, preventing them from tilting and from directly contacting the ultrasonic cleaner.

[0006] In a preferred embodiment of this application, multiple arc-shaped clamping blocks are evenly distributed inside the placement hole, clamping holes are provided between the clamping blocks, and the clamping blocks are elastically connected to the sidewall of the placement hole.

[0007] When a test tube is placed into the clamping hole, the clamping block abuts against the side wall of the test tube to fix it in place. Since the clamping block is elastically connected to the side wall of the placement hole, test tubes of different diameters can be placed in one placement hole, thus expanding the compatibility of the test tube rack.

[0008] In a preferred embodiment of this application, at least two fixed posts are fixedly installed on the placement rack, and at least one extension rod is detachably connected to each fixed post. A support tube adapted to the extension rod is provided on the cleaning basket, and the extension rod and the support tube are pluggable and detachable.

[0009] Once the placement rack is inserted into the cleaning basket, the support tube and extension rod work together to prevent the placement rack from shaking inside the cleaning basket, thus achieving a positioning function.

[0010] In a preferred embodiment of this application, one end of the extension rod is provided with a connecting hole adapted to the fixing post, and the other end of the extension rod is provided with a connecting post adapted to the connecting hole.

[0011] By using connecting columns and connecting holes, multiple extension rods can be combined and connected to the placement rack, increasing the distance between the placement plate and the support components according to different test tube specifications; avoiding excessive length of test tubes exposed outside the test tube rack; thereby improving the stability of the test tubes inside the test tube rack.

[0012] In a preferred embodiment of this application, a support plate is provided on the cleaning basket, and the support plate is located directly below the support tube. When the placement rack is inserted into the cleaning basket, the extension rod and the support plate abut against each other.

[0013] By setting up the support plate, when the rack is inserted into the cleaning basket, the extension rod is prevented from contacting the bottom wall of the cleaning tank inside the ultrasonic cleaner.

[0014] In a preferred embodiment of this application, the bottom of the cleaning basket is provided with a mesh, the support member is located inside the mesh, and the support member is fixedly connected to the side wall of the mesh by a connecting rod.

[0015] In addition to the technical problems solved by the present invention, the technical features constituting the technical solutions, and the advantages brought about by the technical features of these technical solutions as described above, other technical problems that the present invention can solve, other technical features contained in the technical solutions, and the advantages brought about by these technical features will be further described in detail with reference to the accompanying drawings.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-3 As shown, the ultrasonic cleaner test tube rack provided in this embodiment includes a cleaning basket 01 and a placement rack 02 for use in the cleaning tank of the ultrasonic cleaner. The placement rack 02 includes a placement hole 03 for placing test tubes. Multiple arc-shaped clamping blocks 04 are evenly distributed within the placement hole 03. The multiple clamping blocks 04 are combined to form a clamping hole. The clamping blocks 04 are connected to the side wall of the placement hole 03 by springs 05. One end of the spring 05 is fixed to the inner wall of the placement hole 03, and the other end of the spring 05 is connected to the clamping block 04 towards the center of the placement hole 03. When a test tube is placed into the clamping hole, the clamping block 04 abuts against the side wall of the test tube under the action of the spring 05, and the test tube is fixed by the evenly distributed clamping blocks 04. Due to the spring 05, test tubes of different diameters can be placed in the placement hole 03, expanding the compatibility of the test tube rack.

[0022] Please see Figure 1 As shown, the cleaning basket 01 includes a grid-like base plate 06. Support frames 07 are fixedly installed around the base plate 06 by welding. Support tubes 08 are fixedly installed by welding at the connection points of adjacent support frames 07. In other embodiments, two support tubes 08 can be installed diagonally across the cleaning basket 01. An extension rod 09 adapted to the support tubes 08 is provided on the placement frame 02. When the placement frame 02 is inserted into the cleaning basket 01, the cooperation of the support tubes 08 and extension rods 09 prevents the placement frame 02 from shaking within the cleaning basket 01, thus providing a positioning function. A fixing post 10 is fixedly installed on the placement frame 02 by welding. The fixing post 10 has external threads. One end of the extension rod 09 has a connecting hole 11 adapted to the fixing post 10, and the connecting hole 11 has internal threads. The other end of the extension rod 09 has a connecting post 12 adapted to the connecting hole 11. Multiple extension rods 09 can be combined using the connecting post 12 and the connecting hole 11. The extension rod 09 and the placement rack 02 are fixed by the fixing post 10 and the connecting hole 11, so that the extension rod 09 and the placement rack 02 are threadedly connected. After the extension rod 09 and the placement rack 02 are assembled, the extension rod 09 is inserted into the support tube 08, so that the support rack 07 is combined with the cleaning basket 01. When the extension rod 09 is pulled out from the support tube 08, the support rack 07 is separated from the cleaning basket 01, so that the placement rack 02 can be inserted and removed onto the cleaning basket 01, thereby allowing test tubes of different sizes to be placed in the cleaning basket 01.

[0023] To prevent the extension rod 09 on the placement rack 02 from contacting the bottom wall of the cleaning tank inside the ultrasonic cleaner when the placement rack 02 is inserted into the cleaning basket 01, a support plate 13 is provided on the base plate 06. The support plate 13 is located directly below the support tube 08. When the placement rack 02 is installed on the base frame, the extension rod 09 and the support plate 13 abut against each other, thereby preventing the extension rod 09 from passing through the base plate 06 and contacting the bottom wall of the cleaning tank.

[0024] Please see Figure 3 As shown, the base plate 06 consists of multiple support strips. Mesh openings 14 are provided between adjacent support strips, and support members 15 are installed within the mesh openings 14. The support members 15 are circular or cross-shaped. The support members 15 are fixedly connected to the sidewalls of the mesh openings 14 via connecting rods 16. When the test tube is placed vertically, the bottom of the test tube contacts the support member 15 to support it, preventing the test tube from passing through the mesh openings 14 and directly contacting the bottom of the cleaning tank.

[0025] Therefore, in actual use, for example, if it is necessary to place a 1ml test tube into an ultrasonic cleaner for processing, firstly, select an extension rod 09 and install it on each fixed post 10 on the placement rack 02. Then, insert the extension rod 09 into the support tube 08, so that the connecting post 12 on the extension rod 09 contacts the support plate 13, thereby assembling the placement rack 02 and the cleaning basket. Finally, place the 1ml test tube into the placement hole 03. The 1ml test tube contacts the support member 15 on the cleaning basket, and the support member 15 supports the 1ml test tube to prevent it from falling. The clamping plate in the placement hole 03 stabilizes the 1ml test tube, preventing it from wobbling within the placement hole 03.

[0026] For example, if a 50ml test tube needs to be placed in an ultrasonic cleaner for processing, since the 50ml test tube is longer than a 1ml test tube, multiple extension rods 09 are selected and combined before being connected to the placement rack 02, increasing the distance between the placement plate and the support member 15 on the base plate 06. This prevents excessive length of the 50ml test tube from protruding outside the rack after it is placed inside, thus improving the stability of the 50ml test tube within the rack.

[0027] If the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0028] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
