Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, and in particular to a horizontal oscillator. Background Technology

[0002] A horizontal oscillator is a device capable of generating periodic motion in the horizontal direction, widely used in scientific research, industrial production, and educational demonstrations. Driven by an electric motor or other power source, it causes an object or sample mounted on it to perform stable horizontal reciprocating motion. This motion can be a simple left-right oscillation or a more complex trajectory, such as a circular or elliptical path. Horizontal oscillators are used in chemical experiments for mixing solutions, in biomedical research for cell culture, and in materials science for sample processing. Their stability and controllability are crucial for ensuring the accuracy and repeatability of experimental results.

[0003] Chinese utility model patent publication number CN 218189288 U discloses a horizontal oscillator design aimed at improving stability. This design uses a protrusion on the oscillator, with the force of a first spring firmly pressing this protrusion against the outer wall of a test tube, ensuring the test tube remains stable during oscillation and avoiding displacement or collisions caused by oscillation. However, this design also presents a significant problem: the contact between the protrusion and the outer wall of the test tube is point contact. While this enhances local fixation, in practical use, when the test tube needs to be picked up or put down, the operator must overcome the restoring force generated by the first spring. This not only increases the difficulty of operation but also carries the risk of damaging the test tube or injuring the operator due to improper force. Therefore, how to simplify the picking and putting-down operation process while ensuring test tube stability has become an urgent problem to be solved in this horizontal oscillator design. Utility Model Content

[0004] The technical problem to be solved by this invention is to provide a horizontal oscillator.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A horizontal oscillator includes an oscillator body, a cover hinged to one side of the oscillator body, a locking assembly for locking the cover and the oscillator body, and a locking mechanism. The oscillator body has multiple placement slots. Receiving slots are provided on both sides of the placement slots on the oscillator body. The locking mechanism includes two cylinders and annular airbags of the same number as the placement slots. Each cylinder includes a cylinder body and a piston rod. The cylinder bodies are respectively located within two receiving slots and rotatably connected to the inner walls of the receiving slots. The end of the piston rod is hinged to the lower end of the cover. A groove for placing the airbags is provided at the upper end of each placement slot. The airbags are respectively disposed within each groove. An inlet and outlet are provided at the tail end of the cylinder body, and the inlet and outlet are connected to the airbags on that side via flexible hoses. A fixing plate is provided at the upper end of each airbag, and the fixing plate is fixedly connected to the oscillator body. A through hole corresponding to the placement slot is provided on the fixing plate.

[0007] Preferably, a short shaft is fixedly connected to the end of the piston rod, and a connecting seat is provided at the lower end of the cover, with the short shaft rotatably connected to the connecting seat.

[0008] Preferably, the cylinder body is provided with a pivot, which is rotatably connected to the inner wall of the receiving groove.

[0009] Preferably, the oscillator body is provided with a channel for the flexible tube to pass through.

[0010] Preferably, the fixing plate is fixed to the oscillator body by bolts.

[0011] The above technical solution has the following advantages:

[0012] This invention's test tube fixing mechanism employs an innovative airbag clamping method, significantly improving the fixing effect and ease of operation. Specifically, the larger contact area between the airbag and the test tube provides a more uniform and secure fixing force, effectively avoiding the test tube damage caused by excessive local pressure that can occur with traditional spring-type fixing. When the user closes the lid, the lid drives the cylinder to inject an appropriate amount of air into the airbag, causing it to inflate and tightly adhere to the test tube, thus achieving a stable clamping effect. When the lid is opened, the lid reverses the action, causing the air in the airbag to quickly flow back into the cylinder, causing the airbag to contract and separate from the test tube surface. At this point, the test tube can be easily removed or placed in, greatly simplifying the experimental procedure and improving work efficiency. This design not only solves the shortcomings of traditional horizontal shakers in test tube fixing but also significantly improves the user experience. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] As shown in the attached figure, a horizontal oscillator includes an oscillator body 1, a cover 2 hinged to one side of the oscillator body 1, a locking assembly 3 for locking the cover 2 and the oscillator body 1, and a locking mechanism for locking a test tube (not shown in the figure); the oscillator body 1 is provided with a plurality of placement slots 5; the oscillator body 1 is provided with receiving slots 6 on both sides of the placement slots 5; the locking mechanism includes two cylinders 8 and annular air bladders 7 in the same number as the placement slots 5; each cylinder 8 includes a cylinder body 9 and a piston rod 10, the cylinder bodies of the two cylinders 8... 9 are respectively located in the two receiving grooves 6 and are rotatably connected to the inner wall of the receiving grooves 6; the end of the piston rod 10 is hinged to the lower end of the cover 2; the upper end of the placement groove 5 is provided with a groove 4 for placing the airbag 7; the airbag 7 is respectively placed in each groove 4; the tail end of the cylinder body 9 is provided with an air inlet and exhaust port (not shown in the figure), and the air inlet and exhaust port are respectively connected to the airbag 7 on the same side through a hose 11; a fixing plate 12 is provided at the upper end of the airbag 7, and the fixing plate 12 is fixedly connected to the oscillator body 1; the fixing plate 12 is provided with a through hole 13 corresponding to the placement groove 5.

[0022] As a specific technical solution in this embodiment, a short shaft 14 is fixedly connected to the end of the piston rod 10, and a connecting seat 15 is provided at the lower end of the cover 2. The short shaft 14 is rotatably connected to the connecting seat 15. Obviously, the piston rod 10 and the cover 2 can also adopt other commonly used hinged methods.

[0023] As a specific technical solution in this embodiment, a pivot 16 is provided on the cylinder body 9. The pivot 16 is rotatably connected to the inner wall of the receiving groove 6. In this embodiment, the pivot 16 is located in the middle of the cylinder body 9, but obviously it can also be provided in other suitable positions of the cylinder body 9.

[0024] As a specific technical solution in this embodiment, the oscillator body 1 is provided with a channel (not shown in the figure) for the hose 11 to pass through, so as to hide the hose 11.

[0025] As a specific technical solution in this embodiment, the fixing plate 12 is fixedly connected to the oscillator body 1 by bolts to facilitate the disassembly and maintenance of the airbag 7. Obviously, the fixing plate 12 and the oscillator body 1 can also be fixed by other commonly used methods such as snap-fit.

[0026] When using this invention, open the locking assembly 3, lift the cover 2 upwards, and the piston rod 10 moves with the cover 2. The cylinder 8 deflects to a certain extent under the action of the cover 2, and the air in the airbag 7 enters the cylinder 9 through the hose 11 and the inlet and outlet ports. The airbag 7 retracts, and the test tube can be easily placed into the placement slot 5. Then, close the cover 2 downwards, and the locking assembly 3 locks the cover 2 and the vibrator body 1. During the closing process of the cover 2, the piston rod 10 moves with it, and the cylinder 8 deflects synchronously. The piston rod 10 delivers the air in the cylinder 9 to the airbag 7 through the inlet and outlet ports and the hose 11. The airbag 7 inflates and holds the test tube tightly. At this time, the horizontal vibrator can be started to horizontally vibrate the sample in the test tube. After the vibration is completed, repeat the above steps of opening the cover 2 to easily remove the test tube.

[0027] The air bladder 7 of this invention has a large contact area with the test tube, providing a more uniform and secure fixing force, effectively avoiding the test tube damage caused by excessive local pressure that may occur with traditional spring-type fixing. When the user closes the cover 2, the cover 2 drives the cylinder 8 to inject an appropriate amount of air into the air bladder 7, causing the air bladder 7 to inflate and tightly adhere to the test tube, thus achieving a stable clamping of the test tube. When the cover 2 is opened, the cover 2 drives the cylinder 8 in the opposite direction, causing the air in the air bladder 7 to quickly flow back into the cylinder 8, and the air bladder 7 to contract and separate from the surface of the test tube. At this time, the test tube can be easily removed or placed in, greatly simplifying the experimental operation process and improving work efficiency.
