Description

Technical Field

[0001] The utility model relates to the technical field of strong magnetic stirrers, in particular to a strong magnetic stirrer with stable performance. Background Art

[0002] A strong magnetic stirrer is an instrument commonly used in laboratories, mainly used for mixing liquids, especially low-viscosity liquids or solid-liquid mixtures. Its basic principle is to use the characteristics of magnetic field that like charges repel each other and opposite charges attract each other, and to use the magnetic field to push the magnetic stirrer placed in the container to rotate in a circle, thereby achieving the purpose of stirring the liquid.

[0003] At present, most of the existing strong magnetic stirrers do not have a protective structure for the stirring container. When a person places the container on the stirrer, if the container is accidentally touched, the container may be offset, tipped over, or even dropped and damaged. The displacement of the container will also reduce the magnetic stirring effect, resulting in poor stability of the strong magnetic stirrer and reduced practicality of the stirrer. Therefore, we propose a strong magnetic stirrer with stable performance to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a strong magnetic stirrer with stable performance, which solves the problem that most of the existing strong magnetic stirrers in the prior art do not have a protective structure for the stirring container. If a person accidentally touches the container when taking the container, the container may be offset, tipped over, or even dropped and damaged. The deviation of the container will also cause a reduction in the magnetic stirring effect, resulting in poor stability of the strong magnetic stirrer and reduced practicality of the stirrer.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A strong magnetic stirrer with stable performance comprises a stirrer body, two support plates are symmetrically arranged on one side of the top of the stirrer body, and the bottoms of the two support plates are fixedly installed on one side of the top of the stirrer body, two connecting blocks are symmetrically arranged between the two support plates, two lower arc seats are symmetrically arranged on one side of the two connecting blocks, upper arc seats are arranged above the two lower arc seats, bolts are arranged on one side of the bottom of the two lower arc seats, and limiting rods are fixedly connected to one side of the top of the two lower arc seats, and a clamping assembly connected to the two connecting blocks is arranged between the two support plates.

[0007] Preferably, a threaded hole is provided on one side of the bottom of the two upper arc seats, the top ends of the two bolts pass through the top of the adjacent lower arc seats and are screwed together with the threaded holes, and a limiting hole is provided on the other side of the bottom of the two upper arc seats, and the top ends of the two limiting rods are adapted to the adjacent limiting holes.

[0008] Preferably, the clamping assembly includes a motor arranged on one side of one of the support plates, the bottom of the motor is installed with the adjacent support plate side wall through a bracket, the output end of the motor is driven and connected with a bidirectional screw rod, and the end of the bidirectional screw rod away from the motor is rotatably connected with the adjacent side wall of the other support plate.

[0009] Preferably, the clamping assembly further comprises two screw sleeves respectively sleeved on the two ends of the bidirectional screw rod, and one side of the outer ring of the two screw sleeves is fixedly connected to one side of the adjacent connecting block.

[0010] Preferably, a guide rod is commonly sleeved inside the two screw sleeves, and both ends of the guide rod are fixedly connected to the side walls of the adjacent support plates.

[0011] Preferably, a plurality of cushions are fixedly mounted on the inner arc surfaces of the two lower arc seats and the two upper arc seats.

[0012] The utility model has at least the following beneficial effects:

[0013] The starting motor drives the bidirectional screw rod to make the two screw sleeves move towards each other, and then drives the lower arc seat to move together through the connecting block, and clamps and positions the outside of the container placed on the top of the agitator body. By holding the bottom end of the bolt and rotating it to engage the bolt with the threaded hole, the upper arc seat moves upward to facilitate the adjustment of the distance between the upper arc seat and the lower arc seat, adapt to different container heights and limit the outside of the container to prevent personnel from colliding with the container to cause it to deviate or tip over, resulting in damage to the container or loss of internal liquid, thereby improving the stability and practicality of the high-strength magnetic agitator during operation.

[0014] The utility model also has the following beneficial effects:

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Reference Figure 1-5 A strong magnetic stirrer with stable performance comprises a stirrer body 1, two support plates 5 are symmetrically arranged on one side of the top of the stirrer body 1, and the bottoms of the two support plates 5 are fixedly installed on one side of the top of the stirrer body 1, two connecting blocks 6 are symmetrically arranged between the two supporting plates 5, two lower arc seats 7 are symmetrically arranged on one side of the two connecting blocks 6, upper arc seats 8 are arranged above the two lower arc seats 7, bolts 9 are arranged on one side of the bottom of the two lower arc seats 7, and the tops of the two lower arc seats 7 are fixedly connected to limit rods 10, and a limit rod 10 is arranged between the two support plates 5. There is a clamping assembly connected to the two connecting blocks 6. Specifically, the container is placed on the magnetic disk on one side of the top of the agitator body 1, and then the clamping assembly is started to drive the two connecting blocks 6 to approach each other, and the adjacent lower arc seat 7 and upper arc seat 8 are driven by the connecting blocks 6 to move to clamp and limit the two sides of the outside of the container. At the same time, the height distance between the adjacent upper arc seat 8 and the lower arc seat 7 can be adjusted by adjusting the rotating bolt 9, which is suitable for limiting the outside of containers of different heights, further improving the stability of the strong magnetic agitator during operation, and improving the practicability of the strong magnetic agitator.

[0025] Furthermore, threaded holes are provided on one side of the bottom of the two upper arc seats 8, and the top ends of the two bolts 9 penetrate the top of the adjacent lower arc seat 7 and are screwed together with the threaded holes. Limiting holes are provided on the other side of the bottom of the two upper arc seats 8, and the top ends of the two limiting rods 10 are adapted to the adjacent limiting holes. Specifically, through the provision of the bolts 9, personnel can hold the bottom end of the bolts 9 and rotate them to make the bolts 9 rotate and rotate with the threaded holes at the bottom of the adjacent upper arc seats 8, and through the limiting of the limiting rods 10 and the limiting holes, the upper arc seats 8 are moved upward, thereby facilitating the adjustment of the distance between the upper arc seat 8 and the lower arc seat 7, adapting to different container heights placed on the magnetic disc of the strong magnetic stirrer, and limiting the outside of the container to prevent personnel from colliding with the container and causing it to shift or tip over during operation.

[0026] Furthermore, the clamping assembly includes a motor 2 arranged on one side of one of the support plates 5, the bottom of the motor 2 is installed with the side wall of the adjacent support plate 5 through a bracket, the output end of the motor 2 is driven and connected with a bidirectional screw rod 3, and the end of the bidirectional screw rod 3 away from the motor 2 is rotatably connected with the adjacent side wall of the other support plate 5. Specifically, through the setting of the support plates 5, the two support plates 5 can protect the bidirectional screw rod 3 and the motor 2, etc., to increase their stability during operation.

[0027] Furthermore, the clamping assembly also includes two screw sleeves 4 respectively sleeved on the two ends of the outside of the bidirectional screw rod 3, and one side of the outer circle of the two screw sleeves 4 is fixedly connected to one side of the adjacent connecting block 6. Specifically, through the setting of the screw sleeve 4, the bidirectional screw rod 3 is driven to rotate by starting the motor 2, and the bidirectional screw rod 3 then produces a lateral displacement of the two screw sleeves 4 approaching each other. The screw sleeve 4 then drives the lower arc seat 7 to move together through the adjacent connecting block 6, and clamps and positions the outside of the container placed on the top of the agitator body 1, thereby preventing people from accidentally colliding with the container to cause it to deviate or tip over, resulting in damage to the container or loss of internal liquid.

[0028] Furthermore, a guide rod 12 is commonly sleeved inside the two screw sleeves 4, and both ends of the guide rod 12 are fixedly connected to the side walls of the adjacent support plate 5. Specifically, through the setting of the guide rod 12, the guide rod 12 can limit the two screw sleeves 4 to prevent the screw sleeves 4 from rotating together with the bidirectional screw rod 3.

[0029] Furthermore, the inner arc surfaces of the two lower arc seats 7 and the two upper arc seats 8 are fixedly mounted with a plurality of soft pads 11. Specifically, through the arrangement of the soft pads 11, the soft pads 11 are soft, so that when the two upper arc seats 8 and the two lower arc seats 7 are close to each other to clamp the outside of the container, excessive force is applied to damage the outside of the container.

[0030] In summary:

[0031] By starting the motor 2 to drive the bidirectional screw rod 3 to rotate, the bidirectional screw rod 3 will cause the two screw sleeves 4 to produce a lateral displacement close to each other, and the screw sleeve 4 will then drive the lower arc seat 7 to move together through the adjacent connecting block 6, and clamp and position the outside of the container placed on the top of the agitator body 1, so as to avoid the situation where people accidentally collide with the container to cause it to deviate or tip over, resulting in damage to the container or loss of internal liquid. People can hold the bottom end of the bolt 9 and rotate it to make the bolt 9 rotate and rotate with the threaded hole at the bottom of the adjacent upper arc seat 8, and through the limiting of the limiting rod 10 and the limiting hole, the upper arc seat 8 is moved upward, thereby facilitating the adjustment of the distance between the upper arc seat 8 and the lower arc seat 7, adapting to different container heights placed on the magnetic disc of the strong magnetic agitator, and limiting the outside of the container, so that people can avoid colliding with the container to cause it to deviate or tip over during operation, thereby improving the stability of the strong magnetic agitator during operation and the practicality of the strong magnetic agitator.
