Abstract
Description
Technical Field
[0001] This application relates to the field of test tube racks, and more particularly to liftable oscillating test tube racks. Background Technology
[0002] A water bath test tube rack is a device used to fix test tubes in a water bath environment, mainly for water bath heating operations of test tubes in laboratories. It can effectively fix the test tubes, preventing them from floating or tilting during the water bath process, and ensuring the smooth progress of experiments.
[0003] Existing test tube racks typically hold the test tubes in place within the water bath. However, this makes it difficult to shake or vibrate the test tubes during the water bath process and also makes it impossible to simultaneously control the water bath height, resulting in reduced work efficiency. Utility Model Content
[0004] To address the aforementioned issues, this application provides a height-adjustable oscillating test tube rack.
[0005] The liftable oscillating test tube rack provided in this application adopts the following technical solution:
[0006] A height-adjustable oscillating test tube rack includes a fixed frame and a test tube rack body. The fixed frame is provided with a lifting component for raising and lowering the test tube rack body and a shaking component for oscillating the test tube rack body. The shaking component includes two movable tubes disposed on both sides of the fixed frame. A movable rod is slidably connected to one end of each movable tube. A connecting block is fixedly connected to the end of each movable rod away from the movable tube. One side wall of each connecting block is fixedly connected to the fixed frame. A first electric push rod is fixedly connected to the side wall of each movable tube near the connecting block. The output end of each first electric push rod is fixedly connected to the connecting block. A fixing component is provided on the movable tube for fixing the device in a water bath.
[0007] By adopting the above technical solution, during use, the test tubes are placed in the test tube rack body, and then the device is fixed in the water bath by the fixing component. The lifting component is activated to move the test tube rack body downwards to a suitable position, placing the test tubes in the water. Then, the first electric push rod is activated to reciprocate, driving the moving rod to extend and retract within the moving tube. The connecting block pulls the fixed frame, causing the test tube rack body to move accordingly. The test tubes sway horizontally in the water with the test tube rack body, minimizing the problems of difficulty in uniformly shaking and oscillating the test tubes during the water bath process and the inability to effectively control the sample water bath height, which would otherwise reduce work efficiency.
[0008] Preferably, the lifting assembly includes two second electric push rods respectively fixedly connected to both sides of the upper surface of the fixed frame. The output end of the second electric push rod passes through the fixed frame and is fixedly connected to the side wall of the test tube rack body. Guide rods are provided at all four ends of the upper surface of the fixed frame. The bottom ends of the guide rods all pass through the fixed frame and are fixedly connected to the side wall of the test tube rack body.
[0009] By adopting the above technical solution, after the test tube is placed on the test tube rack body, the test tube rack body can be pushed down in the fixed frame by activating the second electric push rod, immersing the test tube in water. After the water bath is stopped, the test tube rack body is raised in the fixed frame, making it convenient to remove the test tube from the test tube rack body.
[0010] Preferably, the fixing assembly includes two fixing tubes respectively fixedly connected to one side of the moving tube, and threaded rods are threadedly connected to both ends of the fixing tubes, with L-shaped abutment blocks rotatably connected to each threaded rod.
[0011] By adopting the above technical solution, the fixed tube is placed on the water bath, and then the threaded rod is rotated to move the threaded rod in the fixed tube, which drives the L-shaped abutment blocks to move. The L-shaped abutment blocks abut against the side wall of the water bath, which can fix the moving tube and make the test tube rack body stably located in the water bath. The moving rod moves to make horizontal rocking.
[0012] Preferably, the end of each L-shaped abutment block away from the threaded rod is fixedly connected with a rubber pad for abutting against the side wall of the water bath.
[0013] By adopting the above technical solution, the rubber pad abuts against the side wall of the water bath during the movement of the L-shaped abutment block, which can reduce the wear on the side wall of the water bath and increase the friction between the rubber pad and the water bath, thereby improving the stability of the fixation.
[0014] Preferably, the movable tube has guide grooves on the side wall near the fixed frame, and a guide block is slidably connected in the guide groove. The end of the guide block away from the guide groove is fixedly connected to the fixed frame.
[0015] By adopting the above technical solution, the stability of the fixed frame movement can be improved by using guide grooves and guide blocks, and the shaking of the fixed frame during movement can be prevented.
[0016] Preferably, the inner walls of the holes in the test tube rack body are all fixedly connected with rubber rings to improve the stability of the test tubes.
[0017] By adopting the above technical solution, when the test tube is inserted into the hole in the test tube rack body, the elastic rubber ring can fit against the side wall of the test tube, improving the stability of the test tube in the test tube rack body and preventing the test tube from colliding with the hole wall.
[0018] Preferably, each of the guide grooves is fixedly connected to a limiting rod, and the guide blocks are respectively sleeved on the limiting rods and form a sliding arrangement.
[0019] By adopting the above technical solution, the stability of the guide block sliding in the guide groove can be improved by using the limiting rod, and the guide block can be prevented from leaving the guide groove.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. This application utilizes the cooperative arrangement of structures such as a moving tube, a moving rod, and a first electric push rod. In use, the test tube is placed in the test tube rack body, and then the device is fixed in the water bath by the fixing component. The lifting component is activated to move the test tube rack body downward to a suitable position so that the test tube is in the water. Then, the first electric push rod is activated to perform reciprocating motion, which drives the moving rod to extend and retract in the moving tube. The connecting block pulls the fixing frame to move, so that the test tube rack body moves accordingly. The test tube sways horizontally in the water with the test tube rack body, which avoids the problems of difficulty in uniformly shaking and oscillating the test tube and ineffective control of the sample water bath height during the water bath process, which leads to reduced work efficiency.
[0022] 2. By placing the fixed tube on the water bath, and then rotating the threaded rod to move the threaded rod in the fixed tube, the L-shaped abutment blocks are moved, so that the L-shaped abutment blocks abut against the side wall of the water bath, which can fix the moving tube and make the test tube rack body stably located in the water bath. The horizontal rocking is achieved by moving the moving rod. Attached Figure Description

Detailed Implementation
[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0029] This application discloses a liftable oscillating test tube rack.
[0030] Reference Figure 1 , Figure 2 and Figure 3 The liftable vibrating test tube rack includes a fixed frame 1 and a test tube rack body 2. The test tube rack body 2 is made of stainless steel and has two layers. Each layer has three rows of holes with nine holes per row. The test tube rack body 2 can also be made into two layers according to the usage requirements. The dimensions are 18 cm wide, 35 cm long, and 5 cm high. Each layer has eight rows of holes with 30 holes per row and a diameter of 1 cm. The fixed frame 1 is equipped with a lifting component for lifting the test tube rack body 2 and a shaking component for vibrating the test tube rack body 2. The shaking component includes a moving tube 3, a moving rod 4, a connecting block 5, and a first electric push rod 6.
[0031] Two movable tubes 3 are provided, respectively located on both sides of the fixed frame 1. Two movable rods 4 are provided, respectively slidably connected to one end of the movable tube 3. Two connecting blocks 5 are provided, respectively fixedly connected to the end of the movable rod 4 away from the movable tube 3. One side wall of each connecting block 5 is fixedly connected to the fixed frame 1. Two first electric push rods 6 are provided, respectively fixedly connected to the side wall of the movable tube 3 near the connecting block 5. The output end of the first electric push rod 6 is fixedly connected to the connecting block 5. The movable tube 3 is provided with a fixing component for fixing the device in the water bath.
[0032] Reference Figure 1 and Figure 4 The lifting assembly includes two second electric push rods 7, which are respectively fixedly connected to both sides of the upper surface of the fixed frame 1. The output end of the second electric push rod 7 passes through the fixed frame 1 and is fixedly connected to the side wall of the test tube rack body 2. Guide rods 8 are provided at all four ends of the upper surface of the fixed frame 1. The bottom ends of the guide rods 8 pass through the fixed frame 1 and are fixedly connected to the side wall of the test tube rack body 2. After the test tube is placed on the test tube rack body 2, the test tube rack body 2 can be pushed down in the fixed frame 1 by activating the second electric push rod 7, immersing the test tube in water. After the water bath is stopped, the test tube rack body 2 is raised in the fixed frame 1 to facilitate the removal of the test tube in the test tube rack body 2.
[0033] Reference Figure 1 and Figure 2The fixing assembly includes two fixing tubes 9, which are respectively fixedly connected to one side of the moving tube 3. Both ends of the fixing tube 9 are threadedly connected to threaded rods 10, and L-shaped abutment blocks 11 are rotatably connected to the threaded rods 10. By placing the fixing tube 9 on the water bath, and then rotating the threaded rods 10 to move the threaded rods 10 in the fixing tube 9, the L-shaped abutment blocks 11 are moved and abut against the side wall of the water bath, which can fix the moving tube 3 and make the test tube rack body 2 stably located in the water bath. The moving rod 4 moves to make horizontal rocking.
[0034] Reference Figure 1 and Figure 2 Each L-shaped abutment block 11 has a rubber pad 12 fixedly connected to the end away from the threaded rod 10 for abutting against the side wall of the water bath. During the movement of the L-shaped abutment block 11, the rubber pad 12 abuts against the side wall of the water bath, which can reduce the wear on the side wall of the water bath and increase the friction between it and the water bath, thereby improving the stability of the fixation.
[0035] Reference Figure 1 , Figure 2 and Figure 3 The moving tube 3 has a guide groove 13 on the side wall near the fixed frame 1. A guide block 14 is slidably connected in the guide groove 13. The end of the guide block 14 away from the guide groove 13 is fixedly connected to the fixed frame 1. The guide groove 13 and the guide block 14 can improve the stability of the movement of the fixed frame 1 and prevent the fixed frame 1 from shaking when it moves.
[0036] Reference Figure 4 The inner walls of the holes in the test tube rack body 2 are all fixedly connected with rubber rings 15 to improve the stability of the test tubes. When the test tubes are inserted into the holes in the test tube rack body 2, the elastic rubber rings 15 can fit against the side walls of the test tubes, improving the stability of the test tubes in the test tube rack body 2 and preventing the test tubes from colliding with the hole walls.
[0037] Reference Figure 3 Each guide groove 13 is fixedly connected to a limiting rod 16, and the guide blocks 14 are respectively sleeved on the limiting rod 16 and form a sliding arrangement. The limiting rod 16 can improve the stability of the guide blocks 14 sliding in the guide groove 13 and prevent the guide blocks 14 from leaving the guide groove 13.
[0038] The implementation principle of the liftable oscillating test tube rack in this embodiment is as follows: During use, test tubes are placed in the test tube rack body 2. The fixed tube 9 is placed on a water bath. Then, the threaded rod 10 is rotated, causing it to move within the fixed tube 9, which in turn moves the L-shaped abutment block 11. This causes the rubber pads 12 to abut against the side walls of the water bath, fixing the moving tube 3 and ensuring the fixed frame 1 is stably positioned on the water bath. Then, the second electric push rod 7 is activated to push the test tube rack body 2 downwards within the fixed frame 1, immersing the test tubes in water. The first electric push rod 6 is then activated to reciprocate, causing the moving rod 4 to extend and retract within the moving tube 3. The connecting block 5 pulls the fixed frame 1, causing the test tubes to sway horizontally in the water along with the test tube rack body 2. This minimizes the difficulty in uniformly oscillating the test tubes and effectively controlling the sample water bath height during the water bath process, thus reducing work efficiency.
[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
