Technical Field
[0001] The utility model relates to the technical field of testing equipment, in particular to an oscillation device for a laboratory with a test tube protection function. Background Art
[0002] In testing, it is necessary to mix samples with chemical reagents for reaction. In order to improve the reaction efficiency, it is necessary to shake the test tubes sufficiently. However, some samples need a long reaction time with chemical reagents. If the manual shaking method is used, the labor cost is relatively high. In addition, when the laboratory conducts sample tests, it is often necessary to test and compare a large number of samples. Therefore, the workload is large, and it is more difficult to meet the requirements by the manual shaking method. Therefore, in the prior art, a constant temperature oscillator is usually used to heat and oscillate the test tubes. The fixing device in the existing constant temperature oscillator usually sets several springs distributed in a criss-cross manner on the equipment housing, and the test tubes are placed in the cavities formed by multiple springs. The defects of this fixing device are as follows: First, after long-term use, the springs are prone to aging, resulting in a decrease in the spring force, which leads to an enlarged movement range of the test tubes, and it is easy for the test tubes to collide with each other, thereby causing wear of the test tubes. Second, during the oscillation process, the bottom of the test tube and the bottom of the equipment base will also continuously rub against each other, resulting in wear of the test tubes. After long-term use, there is a risk of test tube rupture. Summary of the Utility Model
[0003] In order to solve the above problems, the utility model provides an oscillation device for a laboratory with a test tube protection function, which can improve the service life of the equipment and ensure that the test tubes will not be damaged during use.
[0004] The technical solution of the utility model: An oscillation device for a laboratory with a test tube protection function includes an equipment housing, a connection base fixedly connected to the equipment housing, a first sliding base slidably connected to the connection base, a second sliding base slidably connected to the first sliding base, a fixed housing fixedly connected to the second sliding base, several first rubber rods connected to the fixed housing, several second rubber rods connected to the fixed housing, a first hydraulic cylinder for driving the first sliding base to move along the X-axis direction, a second hydraulic cylinder for driving the second sliding base to move along the Y-axis, and a controller. The first rubber rods and the second rubber rods are evenly distributed along the X-axis direction and the Y-axis direction respectively. A cavity can be formed between the first rubber rods and the second rubber rods. The first rubber rods and the second rubber rods are made of soft rubber material. The cavity can accommodate test tubes. The controller is electrically connected to the first hydraulic cylinder and the second hydraulic cylinder respectively.
[0005] By adopting the above technical solution, when the test tube needs to be oscillated, first, the test tube is placed in the cavity, and then the first hydraulic cylinder and the second hydraulic cylinder are controlled by the controller to respectively drive the first sliding base and the second sliding base to slide in the X-axis direction and the Y-axis direction respectively. Since the first rubber rod and the second rubber rod are provided on the fixed shell, the rubber material has good shock absorption performance and flexibility, so the test tube can be prevented from being damaged when colliding with the first rubber rod and the second rubber rod. In addition, the fixed shell can move back and forth in the X-axis direction and the Y-axis direction with the first sliding base and the second sliding base, so that the test tube placed in the cavity completes the oscillation work.
[0006] A further configuration of the utility model is as follows: the fixed shell is provided with a rubber pad fixedly connected to the fixed shell, the rubber pad is provided with a plurality of limiting holes, the central axes of the limiting holes are respectively coaxially arranged with the central axes of the cavities at corresponding positions, and the diameter of the limiting holes is larger than the diameter of the test tube to be processed.
[0007] By adopting the above technical scheme, since a rubber pad fixedly connected to the fixed shell is provided on the fixed shell, and a plurality of limiting holes are provided on the rubber pad, the central axes of the limiting holes are respectively coaxially arranged with the central axes of the cavities at the corresponding positions, therefore, the bottom of the test tube can be protected. At the same time, since the diameter of the limiting hole is larger than the diameter of the test tube to be processed, it can be ensured that the test tube can oscillate normally after being inserted into the limiting hole.
[0008] The utility model is further configured as follows: the first rubber rod and the second rubber rod are both provided with foam protective sleeves, the foam protective sleeves are respectively sleeved on the first rubber rod and the second rubber rod, and the inner diameters of the foam protective sleeves are respectively adapted to the outer diameters of the first rubber rod and the second rubber rod.
[0009] With the above technical solution, since both the first rubber rod and the second rubber rod are provided with foam protective covers, the foam protective covers are softer in texture and can provide good buffering for the test tube when colliding with the test tube, thereby further improving the service life of the test tube.
[0010] The utility model is further configured as follows: the fixed shell is provided with a plurality of first positioning grooves, a plurality of first mounting holes and a mounting plate connected to the fixed shell, the mounting plate is provided with a plurality of second positioning grooves and a plurality of second mounting holes, when the mounting plate is installed on the fixed shell, the positions of the first positioning grooves and the second positioning grooves correspond one to one, the positions of the first mounting holes and the second mounting holes correspond, the shapes enclosed by the first positioning grooves and the second positioning grooves are respectively adapted to the shapes and sizes of the first rubber rod and the second rubber rod, and the first mounting holes and the second mounting holes are threadedly connected by fixing bolts.
[0011] With the above technical solution, since the shapes enclosed by the first positioning groove and the second positioning groove respectively match the shapes and sizes of the first rubber rod and the second rubber rod, when the foam protective cover, the first rubber rod or the second rubber rod is damaged, by rotating the fixing bolt, the mounting plate is separated from the fixed housing, and then the damaged first rubber rod or the second rubber rod is taken out, the foam protective cover above is replaced, and then it is reinstalled in place. Then, the mounting plate is placed on the fixed housing, aligning the first positioning groove with the second positioning groove one by one, and aligning the positions of the first mounting hole and the second mounting hole. Then, the fixing bolt is installed into the first mounting hole and the second mounting hole, so that the mounting plate is fixed to the fixed housing. This can reduce the maintenance cost of the equipment and improve the service life of the equipment. Description of the Drawings

The first rubber rods 6 and the second rubber rods 7 are uniformly distributed along the X-axis direction and the Y-axis direction respectively. A cavity 11 can be formed between the first rubber rods 6 and the second rubber rods 7. The first rubber rods 6 and the second rubber rods 7 are made of soft rubber material. A test tube can be accommodated in the cavity 11. The controller 10 is electrically connected to the first hydraulic cylinder 8 and the second hydraulic cylinder 9 respectively.
[0017] When it is necessary to oscillate the test tube, first, place the test tube into the cavity 11, and then control the first hydraulic cylinder 8 and the second hydraulic cylinder 9 through the controller 10 to drive the first sliding base 3 and the second sliding base 4 to slide in the X-axis direction and the Y-axis direction respectively. Since the fixed housing 5 is provided with the first rubber rods 6 and the second rubber rods 7, and the rubber material has good shock absorption performance and flexibility, it is possible to avoid the test tube from being damaged when colliding with the first rubber rods 6 and the second rubber rods 7. In addition, the fixed housing 5 can move back and forth in the X-axis direction and the Y-axis direction along with the first sliding base 3 and the second sliding base 4, so that the test tube placed in the cavity 11 can complete the oscillation work.
[0018] The fixed housing 5 is provided with a rubber pad 12 fixedly connected to the fixed housing 5. The rubber pad 12 is provided with a plurality of limiting holes 13. The central axes of the limiting holes 13 are coaxially arranged with the central axes of the corresponding cavities 11. The diameter of the limiting holes 13 is larger than the diameter of the test tube to be processed.
[0019] Since the fixed housing 5 is provided with a rubber pad 12 fixedly connected to the fixed housing 5, and the rubber pad 12 is provided with a plurality of limiting holes 13, and the central axes of the limiting holes 13 are coaxially arranged with the central axes of the corresponding cavities 11, it is possible to protect the bottom of the test tube. At the same time, since the diameter of the limiting holes 13 is larger than the diameter of the test tube to be processed, it is possible to ensure that the test tube can oscillate normally after being inserted into the limiting holes 13.
[0020] The first rubber rods 6 and the second rubber rods 7 are both provided with foam protection sleeves 14. The foam protection sleeves 14 are respectively sleeved on the first rubber rods 6 and the second rubber rods 7. The inner diameters of the foam protection sleeves 14 are respectively adapted to the outer diameters of the first rubber rods 6 and the second rubber rods 7.
[0021] Since the first rubber rod 6 and the second rubber rod 7 are both provided with foam protective sleeves 14, the texture of the foam protective sleeves 14 is softer, and it can play a good buffering role for the test tube when colliding with the test tube, thereby further improving the service life of the test tube.
[0022] The fixed housing 5 is provided with a plurality of first positioning grooves 15, a plurality of first mounting holes 16 and a mounting plate 17 connected to the fixed housing 5. The mounting plate 17 is provided with a plurality of second positioning grooves 18 and a plurality of second mounting holes 19. When the mounting plate 17 is mounted on the fixed housing 5, the positions of the first positioning grooves 15 and the second positioning grooves 18 correspond to each other one by one, the positions of the first mounting holes 16 and the second mounting holes 19 correspond, and the shapes enclosed by the first positioning grooves 15 and the second positioning grooves 18 respectively match the shapes and sizes of the first rubber rod 6 and the second rubber rod 7. The first mounting holes 16 and the second mounting holes 19 are threadedly connected by fixing bolts 20.
[0023] Since the shapes enclosed by the first positioning grooves 15 and the second positioning grooves 18 respectively match the shapes and sizes of the first rubber rod 6 and the second rubber rod 7, when the foam protective sleeve 14 or the first rubber rod 6 or the second rubber rod 7 is damaged, by rotating the fixing bolt 20, the mounting plate 17 is separated from the fixed housing 5, then the damaged first rubber rod 6 or the second rubber rod 7 is taken out, the foam protective sleeve 14 on it is replaced, and then it is reinstalled in place. Then the mounting plate 17 is placed on the fixed housing 5, so that the first positioning grooves 15 are aligned with the second positioning grooves 18 one by one, and the positions of the first mounting holes 16 and the second mounting holes 19 are aligned. Then the fixing bolt 20 is installed into the first mounting hole 16 and the second mounting hole 19, so that the mounting plate 17 and the fixed housing 5 are fixed together, which can reduce the maintenance cost of the equipment and improve the service life of the equipment.
