Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, and in particular to a sample bottle axially fixed and rotating oscillator. Background Technology

[0002] A shaker is a laboratory device primarily used for mixing, dispersing, and blending substances such as liquids, solids, and gases. For example, patent announcement number CN202710374U discloses a temperature-equalizing, double-sided clamping tilting shaker, comprising a frame, a tilting support, a main shaft, a bottle clamping device, an insulation cover, a transmission mechanism, and a motor. The tilting support is fixed to the main shaft, which is mounted on the frame. The bottle clamping device is mounted on the tilting support. The motor drives the main shaft through the transmission mechanism. The connecting component between the tilting support and the bottle clamping device is housed within the insulation cover, which is fixed to the frame. By altering the structure of the bottle clamping device on the tilting shaker, the shaker achieves double-sided clamping of the test bottle, improving not only the clamping speed and reliability but also increasing the clamping range of the device. The bottle clamping device consists of a bottle mouth clamp and a bottle bottom clamp. The bottle mouth clamp consists of a bottle mouth handwheel, a bottle mouth screw, and a bottle mouth limiting plate. The bottle bottom clamp consists of a bottle bottom handwheel, a bottle bottom screw, and a bottle bottom limiting plate. The bottle mouth screw and the bottle mouth limiting plate, as well as the bottle bottom screw and the bottle bottom limiting plate, are fixedly connected. Due to unavoidable installation errors, it is difficult to ensure that the bottle mouth clamp and the bottle bottom clamp are on the same vertical line. The force on the edge of the bottle cap is uneven, resulting in poor sealing of the bottle cap and leakage of the bottle when it is shaken. Summary of the Invention

[0003] In view of this, and to address the above-mentioned shortcomings, it is necessary to propose a sample bottle axially fixed and rotating oscillator with optimized sample bottle sealing.

[0004] A sample bottle axially fixed and rotating oscillator includes a chassis, a turntable, and a clamping assembly. The turntable rotates relative to the chassis. The clamping assembly includes a base plate, a top plate, a screw, and a top cover. The base plate and the top plate are fixed on the turntable. The screw is threadedly engaged with the top plate. When the screw rotates, it moves relative to the top plate. The top cover is located at one end of the screw to clamp the sample bottle between the base plate and the top cover. The screw and the top cover are oscillatingly connected. The end of the top plate is bent.

[0005] Preferably, a turntable is provided on each side of the chassis, the two turntables are arranged in parallel, the two sides of the base plate are fixedly connected to a turntable respectively, and the two sides of the top plate are fixedly connected to a turntable respectively.

[0006] Preferably, there are two clamping components, which are centrally symmetrical about the rotation center of the turntable. The top plates of the two clamping components are a first top plate and a second top plate, and the base plates of the two clamping components are a first base plate and a second base plate. The axially fixed and rotating oscillator of the sample bottle includes two transition plates, which are a first transition plate and a second transition plate.

Detailed Implementation

[0021] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0022] See Figures 1 to 5 This utility model provides a sample bottle axially fixed and rotating oscillator, including a housing 20, a turntable 30, and a clamping assembly 40. The turntable 30 rotates relative to the housing 20. The clamping assembly 40 includes a base plate 41, a top plate 42, a screw 43, and a top cover 44. The base plate 41 and the top plate 42 are fixed on the turntable 30. The screw 43 is threadedly engaged with the top plate 42. When the screw 43 rotates, the screw 43 moves relative to the top plate 42. The top cover 44 is located at one end of the screw 43 to clamp the sample bottle 10 between the base plate 41 and the top cover 44. The screw 43 and the top cover 44 are oscillatingly connected. The end of the top plate 42 is bent.

[0023] For example, "axial fixation" means that the sample bottle 10 is clamped along the direction of the bottom and the cap, and the screw 43 is hinged to the top cap 44.

[0024] For example, the chassis 20 is a hollow box, and the turntable 30 is rotatably connected to the chassis 20 by a rotating shaft that can pass through the turntable 30. The two ends of the rotating shaft are rotatably connected to the two sides of the chassis 20.

[0025] Beneficial effects: If the upper surface of the substrate 41 and the lower surface of the top cover 44 cannot be parallel due to installation accuracy, the top cover 44 can swing relative to the substrate 41. The lower surface of the top cover 44 contacts the circumference of the bottle cap, and the force on the circumference of the bottle cap is uniform, which is conducive to a good seal of the bottle cap and solves the problem of leakage of the sample bottle 10 during vibration. The end of the top plate 42 is bent, increasing the connection length with the turntable 30 and increasing the connection strength with the turntable 30.

[0026] See Figures 1 to 5 Furthermore, a turntable 30 is provided on each side of the chassis 20, and the two turntables 30 are arranged in parallel. The two sides of the base plate 41 are fixedly connected to a turntable 30 respectively, and the two sides of the top plate 42 are fixedly connected to a turntable 30 respectively.

[0027] See Figures 1 to 5 Furthermore, there are two clamping components 40, which are centrally symmetrical about the rotation center of the turntable 30. Figure 1 The clamping assembly 40 located on the back is not shown. The top plates 42 of the two clamping assemblies 40 are the first top plate 42 and the second top plate 42, respectively. The base plates 41 of the two clamping assemblies 40 are the first base plate 41 and the second base plate 41, respectively. The sample bottle axially fixed and flipping oscillator includes two transition plates 50, namely the first transition plate 50 and the second transition plate 50. The two ends of the first transition plate 50 are connected to the first base plate 41 and the second top plate 42, respectively. The two ends of the second transition plate 50 are connected to the first top plate 42 and the second base plate 41, respectively. The first transition plate 50, the first base plate 41, and the second top plate 42 are connected in sequence to form a tortuous shape.

[0028] For example, the first transition plate 50, the first base plate 41, and the second top plate 42 are sequentially connected to form a "Z" shape, and the second transition plate 50, the first top plate 42, and the second base plate 41 are sequentially connected to form a "Z" shape. Multiple screws 43 and top covers 44 can be provided between the first base plate 41 and the first top plate 42 to install multiple sample bottles 10. Similarly, multiple screws 43 and top covers 44 can be provided between the second base plate 41 and the second top plate 42 to install multiple sample bottles 10.

[0029] The tortuous design of the first transition plate 50, the first base plate 41, the second top plate 42, and the second transition plate 50, the first top plate 42, and the second base plate 41 increases the centrifugal radius of the sample bottle 10 and enhances the homogenization effect of the sample bottle 10; it shortens the length of the screw 43, improving stability; the overall length is increased, the connection length with rotation is increased, and the connection strength is increased; the first transition plate 50 supports the first base plate 41 and the second top plate 42, increasing the overall strength, and similar situations will not be repeated; the first transition plate 50 and the second transition plate 50 are not connected, and a hollow space is formed between the first transition plate 50 and the second transition plate 50, which can reduce the air resistance when the clamping assembly 40 rotates.

[0030] See Figures 1 to 5 Furthermore, the top cover 44 includes an upper cover 441, a lower cover 442, and a ball head 443. One end of the screw 43 is provided with a ball head 443, the diameter of which is larger than the diameter of the screw 43. One side surface of the lower cover 442 is provided with a hemispherical recess. The upper cover 441 is provided with a through hole. One end of the through hole is a columnar hole, the diameter of which is larger than the diameter of the screw 43 and smaller than the diameter of the ball. The other end of the through hole is an arc-shaped hole, which connects with the recess to form a ball-and-socket shape that matches the shape of the ball head 443.

[0031] For example, the upper cover 441 and the lower cover 442 can be welded, or the upper cover 441 can have a countersunk hole, and the upper cover 441 and the lower cover 442 can be connected by hex bolts, with the hex bolts embedded in the countersunk hole. During installation, the ball head 443 is first brought into contact with the recess, and then the upper cover 441 passes through the screw 43. The arc-shaped hole presses the ball head 443 to prevent it from coming out. The upper cover 441 and the lower cover 442 are relatively fixed, and the ball head 443 rotates in the ball socket. There is a gap between the outer wall of the screw 43 and the inner wall of the columnar hole, and the screw 43 can swing slightly.

[0032] See Figures 1 to 5 Furthermore, the clamping assembly 40 includes a limiting disk 45, which is disposed on the substrate 41 and has a limiting groove.

[0033] For example, the sample bottle 10 is clamped between the limiting plate 45 and the top cover 44. The top cover 44 is provided with a slot, the shape of which corresponds to the shape of the bottle cap, and the shape of the limiting groove corresponds to the shape of the bottle bottom.

[0034] See Figures 1 to 5 Furthermore, the clamping assembly 40 includes a locking nut 46, which is disposed on the screw 43 and located between the top cover 44 and the top plate 42.

[0035] See Figures 1 to 5 Furthermore, the clamping assembly 40 includes a handwheel 47, which is located at the other end of the screw 43 and is fixedly connected to the screw 43.

[0036] See Figures 1 to 5 Furthermore, the clamping assembly 40 includes an additional plate 48, which is fixedly connected to the top plate 42. The additional plate 48 is threadedly connected to the screw 43, and the additional plate 48 is located between the handwheel 47 and the top plate 42.

[0037] For example, the auxiliary plate 48 is circular, which can increase the threaded connection length between the screw 43 and the top plate 42, and also prevent the handwheel 47 from being too close to the top plate 42, making it difficult to turn the handwheel 47.

[0038] See Figures 1 to 5 Furthermore, the end of the substrate 41 is bent. The bending of the end of the substrate 41 increases the connection length with the turntable 30, thereby increasing the connection strength with the turntable 30.

[0039] See Figures 1 to 5 Furthermore, the end of the top plate 42 is bent toward the handwheel 47. When the worker turns the locking nut 46, the end of the top plate 42 is bent toward the handwheel 47, which can prevent the end of the top plate 42 from scratching the worker's arm and also increase the worker's operating space.

[0040] For example, the chassis 20 is provided with a cover 60, which rotates relative to the chassis 20 to close or open the chassis 20. The cover 60 is provided with a handle 70 and is made of glass for easy observation. A cabinet 80 is provided on one side of the chassis 20. The cabinet 80 contains a motor that drives the turntable 30 to rotate. The specific connection relationship is conventional.

[0041] The modules or units in the device of this utility model embodiment can be merged, divided, or deleted according to actual needs.

[0042] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
