Description

Technical Field

[0001] This utility model relates to a constant temperature shaker, specifically a constant temperature shaker that can be fixed and adjusted. Background Technology

[0002] A constant-temperature shaker is a laboratory device that combines temperature control and oscillation functions, and is widely used in biology, medicine, chemistry and other fields. Its main functions include providing a constant temperature environment and stable oscillation function to promote the growth, metabolism and chemical reactions of biological samples. Existing constant-temperature shakers, such as the one with fixed structure and constant-temperature shaker disclosed in patent CN219647315U, use a first clamp and a second clamp to rigidly hold the bottle body, without a buffer structure during the clamping process, which can easily damage the bottle body. Utility Model Content

[0003] The purpose of this invention is to solve the technical problem of providing a fixed and adjustable constant temperature shaker with a buffer structure when clamping a bottle.

[0004] To solve the above-mentioned technical problems, the present invention provides a fixed and adjustable constant temperature shaker as follows:

[0005] The device includes a shaker body and a bottle for placing samples. A cap is rotatably connected to the shaker body, and a shaker platform is provided inside the shaker body. The bottle is placed on the shaker platform, and plug-in seats are connected to the upper left and right sides of the shaker platform. Limiting frames are detachably connected to the two plug-in seats. The limiting frames include two connecting rods and two abutment plates respectively connected to the two ends of the two connecting rods. Each of the two abutment plates has a first limiting semi-groove on its inner side. Two sets of elastic clamping assemblies corresponding to the two abutment plates are also laterally slidably connected to the two connecting rods. The elastic clamping assemblies include a transverse slide, a clamping plate, and a locking knob. The transverse slide is laterally slidably connected to the two connecting rods. Furthermore, the transverse slide block is connected to multiple transverse slide rods near the abutment plate corresponding to itself; the clamping plate is slidably connected to the multiple transverse slide rods, and each of the multiple transverse slide rods is fitted with a spring; one end of the spring is welded to the clamping plate, and the other end is welded to the transverse slide block; the clamping plate has a second limiting half-groove corresponding to the first limiting half-groove; the two connecting rods are respectively connected to threaded connecting sections corresponding to the two elastic clamping components; each threaded connecting section is threaded with a locking knob, and by rotating the locking knob on the threaded connecting section, the transverse slide block and the clamping plate are pushed closer to the abutment plate corresponding to themselves, thereby clamping the bottle on the first limiting half-groove and the second limiting half-groove.

[0006] Both of the aforementioned connectors have two vertical limiting grooves on their top surfaces; the two ends of the two connecting rods are respectively placed in the two vertical limiting grooves of the two connectors and are limited by limiting covers.

[0007] There are two limiting cover plates in total; the two limiting cover plates are respectively inserted into the two plug-in seats; both ends of the limiting cover plates are connected to connecting ears; the connecting ears are connected to the plug-in seats by bolts.

[0008] The transverse slide block has two transverse sliding rods connected to the side of the abutment plate corresponding to itself.

[0009] Both ends of the two connecting rods are connected to limit blocks.

[0010] The technical effects achieved by this utility model are as follows: In fixing the bottle in this adjustable constant-temperature shaker, the bottle is first placed against the abutment plate. Then, by pushing the transverse slide, the clamping plate is placed against the other side of the bottle. Next, the locking knob is turned onto the threaded connection section. The locking knob pushes the transverse slide laterally, gradually reducing the distance between the transverse slide and the abutment plate. The transverse slide, through a spring, pushes the clamping plate. As the distance between the transverse slide and the abutment plate decreases, the spring is compressed, increasing the spring's thrust on the clamping plate until the bottle is locked between the clamping plate and the abutment plate. This utility model, through its spring design, elastically clamps the bottle between the clamping plate and the abutment plate, making it less prone to damaging the bottle compared to existing rigid clamping methods.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] See Figures 1 to 8 .

[0022] A fixed and adjustable constant temperature shaker includes a shaker body 1 and a bottle 2 for placing samples. A cover 3 is rotatably connected to the shaker body 1. A shaker platform 4 is provided inside the shaker body 1, and the bottle 2 is placed on the shaker platform 4. Insertion seats 5 are connected to the upper left and right sides of the shaker platform 4, and limit frames are detachably connected to the two insertion seats 5. Specifically, the limit frames include two connecting rods 6 and two abutment plates 7 respectively connected to the two ends of the two connecting rods 6. Two vertical limit grooves 21 are provided above each of the two insertion seats 5. The two ends of the connecting rod 6 are respectively placed in the two vertical limiting grooves 21 of the two plug-in seats 5 and limited by the limiting cover plate 22; there are two limiting cover plates 22 in total, and the two limiting cover plates 22 are respectively inserted into the two plug-in seats 5. Both ends of the limiting cover plate 22 are connected to the connecting ears 23, and the connecting ears 23 are connected to the plug-in seats 5 by bolts; when the limiting frame needs to be disassembled, the bolts between the connecting ears 23 and the plug-in seats 5 are unscrewed, and then the limiting cover plate 22 is removed. At this time, the limiting frame can be directly removed from the plug-in seats 5.

[0023] Both abutment plates 7 have a first limiting semi-groove 8 on their inner sides. Two sets of elastic clamping components corresponding to the two abutment plates 7 are also slidably connected to the two connecting rods 6. Specifically, the elastic clamping components include a transverse slide 9, a clamping plate 10, and a locking knob 11. The transverse slide 9 is slidably connected to the two connecting rods 6, and multiple transverse slide rods 12 are connected to the side of the transverse slide 9 closest to the abutment plate 7 corresponding to itself. More specifically, two transverse slide rods 12 are connected to the side of the transverse slide 9 closest to the abutment plate 7 corresponding to itself. The clamping plate 10 is slidably connected to the two transverse slide rods 12, and springs 13 are sleeved on both transverse slide rods 12. One end of the spring 13 is welded to the clamping plate 10, and the other end is welded to the transverse slide 9. Limiting blocks 31 are connected to both ends of the two connecting rods 6. The connecting rods 6 cannot move laterally after being placed on the insertion seat 5 by the limiting blocks 31 at both ends.

[0024] The clamping plate 10 has a second limiting half groove 14 corresponding to the first limiting half groove 8; the two connecting rods 6 are respectively connected to threaded connecting sections 15 corresponding to the two elastic clamping components on both sides. Each threaded connecting section 15 is threaded with a locking knob 11. By rotating the locking knob 11 on the threaded connecting section 15, the transverse slide 9 and the clamping plate 10 are pushed closer to the abutment plate 7 corresponding to themselves, thereby clamping the bottle 2 on the first limiting half groove 8 and the second limiting half groove 14.

[0025] In this invention, the bottle body 2 is clamped by first placing it against the first limiting semi-groove 8 of the abutment plate 7, and then pushing the transverse slide 9 to move laterally so that the second limiting semi-groove 14 of the clamping plate 10 abuts against the other side of the bottle body 2. Next, the locking knob 11 is turned onto the threaded connection section 15 corresponding to itself, and the locking knob 11 is further rotated on the threaded connection section 15. The locking knob 11 pushes the transverse slide 9 towards the abutment plate 7 side corresponding to itself, gradually reducing the distance between the transverse slide 9 and the abutment plate 7. The spring 13 between the transverse slide 9 and the clamping plate 10 is compressed shorter and shorter. The shorter the spring 13, the greater the pushing force of the spring 13 on the clamping plate 10, until the bottle body 2 is locked between the clamping plate 10 and the abutment plate 7. This utility model uses an elastic clamping method to clamp the bottle body 2 by setting the spring 13 between the transverse slide 9 and the clamping plate 10. Compared with the existing rigid clamping, it is not easy to damage the bottle body 2. In terms of fixing and adjusting the bottle body 2, the distance between the clamping plate 10 and the abutment plate 7 can be adjusted to accommodate bottles 2 with different radii.
