Description

Technical Field

[0001] The present application relates to a biomedical test apparatus, and in particular to a conical flask clamping seat and a mixing device. Background Art

[0002] In the laboratory, conical flasks are often used to prepare solutions. The required solutions, powders, etc. are added into the flasks, and then stirred to mix them. The flasks are then used for sampling and testing or for the next step. The mouth of this conical flask is small, and the solution will generally not spill out of the mouth of the flask during stirring. However, due to the characteristics of the bottle shape, when stirring, the solution can often only be stirred within the coverage of the mouth of the flask. If the inner wall near the bottom of the bottle is to be stirred, the stirring rod needs to be tilted, but it is not easy to control the stirring after tilting. Therefore, the stirring rod is generally not tilted too much, and tilting may cause the stirring rod to collide with the mouth of the bottle. In this case, if a better mixing effect is to be achieved, the stirring state without collision needs to be maintained for a long time, which is time-consuming and laborious. Utility Model Content

[0003] In order to address the deficiencies of the above-mentioned prior art, the present application provides a conical flask clamping seat and a mixing device, which can clamp the conical flask and tilt the conical flask at a certain angle to facilitate stirring. The lifting and lowering stirring component can facilitate mixing operations and improve mixing efficiency and automation.

[0004] In order to achieve the above purpose, the utility model adopts the following technologies:

[0005] A conical bottle clamping seat, comprising:

[0006] a base having a pair of spaced apart supports disposed thereon; and

[0007] The supporting plate has a plurality of clamping springs arranged in a circumferential array on it, and the area between the clamping springs is used to place the conical bottle. A rotating seat is provided at the bottom of the supporting plate, and the rotating seat is rotatably arranged between the supports through a rotating shaft.

[0008] The rotating shaft extends out of one of the supports and is coaxially connected with a gear, the gear is meshed with a rack, the rack is slidably matched on a guide rail, and the guide rail is arranged on the base.

[0009] Furthermore, a moving block is connected to the bottom of the rack, and the moving block is threadedly engaged with a screw, one end of the screw is rotatably engaged with a base at one end of the guide rail, and the other end of the screw is connected to the output shaft of the first motor, and the first motor is arranged on the base.

[0011] The conical flask clamping seat;

[0013] The lifting component is arranged on the base, and its movable end is connected to a horizontal plate, and the second motor is installed on the horizontal plate.

[0014] The beneficial effects of the utility model are:

[0015] 1. The clamping seat can clamp the placed conical flask with springs at multiple points in the circumferential direction. The clamping is stable and easy to take off. At the same time, the carrying plate can be rotated to tilt the conical flask to a predetermined angle, which is convenient for mixing and other operations;

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] In one aspect of the embodiments of the present application, a conical bottle holder is provided, such as Figure 1As shown, it includes a base 1 and a carrying plate 2. A pair of spaced supports 11 are provided on the base 1, and the carrying plate 2 is cross-shaped, with a clamping spring 21 on each side. Specifically, the clamping springs 21 are arranged in a circular array along the center of the carrying plate 2, and the area between the clamping springs 21 is used to place the conical bottle. A rotating seat 22 is provided at the bottom of the carrying plate 2, and the rotating seat 22 is rotatably arranged between the supports 11 through a rotating shaft.

[0024] At this time, when the conical bottle is placed between the clamping springs 21, the conical bottle will be confined and stabilized on the carrying plate 2 by the clamping springs 21, and the conical bottle can be tilted by rotating the carrying plate 2. Specifically, the rotation of the carrying plate 2 can be maintained by manual rotation or by setting a related rotation mechanism.

[0025] If a rotating mechanism is set up to achieve this, combined with Figure 1-Figure 2 It can be known that the rotating shaft can be extended out of one of the supports 11 and coaxially connected to the gear 12, the gear 12 is meshed with a rack 13, and the rack 13 is slidably matched on the guide rail 14 provided on the base 1, so that the gear 12 is driven to rotate by operating the rack 13 to move along the guide rail 14, thereby driving the rotating seat 22 to rotate.

[0026] Further preferably, in order to facilitate more accurate and automated control of the movement of the rack 13, a moving block 17 is connected to the bottom of the rack 13, and the moving block 17 is threadedly engaged with a screw 16, one end of the screw 16 is rotatably engaged with a base at one end of the guide rail 14, and the other end of the screw 16 is connected to the output shaft of the first motor 15, and the first motor 15 is arranged on the base 1. Through the forward or reverse rotation of the first motor 15, the screw 16 acts on the moving block 17 threaded thereon to move, so as to drive the rack 13 to move.

[0027] Specifically, on this basis, in order to reasonably utilize the space for the installation and layout of related components, the guide rail 14 adopts a pair of guide plates, and the inner side of the guide plate has a matching platform, and the matching platform is a predetermined distance from the base 1, referring to Figure 2 The rack 13 is matched with the matching platform and limited between the guide plates, and the moving block 17 and the screw rod 16 are located between the guide plates and below the rack 13.

[0028] Another aspect of the embodiments of the present application provides a mixing device, comprising the conical flask clamping seat and stirring assembly described in the above embodiments.

[0029] Specifically, Figure 3-Figure 4As shown, the stirring assembly is arranged above the carrier plate 2, including a tilted stirring rod 3, the upper end of which is connected to one end of a rotating rod 31, and the other end of the rotating rod 31 is connected to the output shaft of a second motor 32, and the output shaft of the second motor 32 is consistent with the axis of the conical flask 4 placed on the carrier plate 2. In order to improve the stirring effect, the inclination angle of the stirring rod 3 is set so that when it is located in the conical flask 4, its lower end exceeds the coverage range of the bottle mouth of the conical flask 4, and in this state, the stirring rod 3 cannot directly enter by vertical lifting and lowering, but can enter by tilting the conical flask 4 through the clamping seat.

[0030] Specifically, in order to facilitate the installation of the conical flask 4 and the removal of the conical flask 4 after the mixing is completed, the mixing device of this example preferably also includes a lifting assembly 34 arranged on the base 1, which can be a lifting cylinder or a vertically arranged linear screw, whose movable end is connected to a horizontal plate 33, and the second motor 32 is installed on the horizontal plate 33.

[0031] When in use, firstly, the entire stirring assembly is raised to a certain height by the lifting assembly 34, and then the conical flask 4 is installed on the clamping seat. After installation, the conical flask 4 is tilted to a certain angle by operating the clamping seat, such as Figure 5 As shown, the stirring assembly is then lowered so that the tilted stirring rod 3 can extend into the conical flask 4, and the process of lowering and extending will not collide with / interfere with the mouth or body of the conical flask 4. The specific insertion position is based on actual needs. Since the conical flask 4 is generally made of transparent material, it can be confirmed by observation. Then, the current tilt state of the conical flask 4 can be maintained, and the second motor 32 can be turned on for stirring, so that the tilted stirring rod 3 rotates with the rotating rod 31. Of course, in this state, it is necessary to ensure that the stirring rod 3 will not collide with the conical flask 4 after traveling one circle with the rotating rod 31. This can be achieved by adjusting the inclination angle of the lifting assembly 34 and the conical flask 4 on the clamping seat. Of course, after the stirring rod 3 enters, the clamping seat can be adjusted as follows: Figure 4 The state shown is used for stirring, thereby achieving stirring disturbance at the lower part of the conical flask 4 outside the coverage of the bottle mouth, and improving the mixing efficiency. More preferably, the maximum tilt angle of the conical flask 4 in two directions can be set, and then while stirring, the first motor 15 is allowed to rotate forward at a low speed for a predetermined time, and then switched to reverse for a predetermined time, and the mixing effect is improved with stirring. Of course, the predetermined time mentioned here needs to match the maximum tilt angle of the conical flask 4 in two directions, and it is specifically based on the fact that within this range, the stirring rod 3 does not bump against the conical flask 4 in the stirring state.

[0032] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
