Description

Technical Field

[0001] The utility model relates to the technical field of biological centrifuges, in particular to a built-in low-speed constant-temperature biological centrifuge. Background Technique

[0002] A biological centrifuge is a device that separates specimens into different components under the action of centrifugal force through rotation. Currently, the built-in biological centrifuge has a low-speed drive mechanism and a constant-temperature mechanism. The low-speed drive mechanism is mainly used to separate biological specimens (such as cells, blood components, proteins, etc.) that are sensitive to high-speed centrifugation and are prone to sample damage or degradation at too high a rotation speed, while the constant-temperature mechanism can ensure that the sample is separated at an ideal temperature to avoid its inactivation.

[0003] However, in the current biological centrifuge with a built-in low-speed constant-temperature mechanism, a single sealing ring is used between the centrifuge lid and the body. When the lid covers the body, the sealing effect of the single sealing ring is poor, and the temperature inside the centrifuge is easily affected by the external environment, increasing the load of the constant-temperature control system. It is impossible to ensure the temperature stability inside the device, thereby affecting the sample. Moreover, the current centrifuge body lacks a stable structure. When the centrifuge is placed on a relatively smooth tabletop for work, the centrifuge is prone to move during operation and there is a safety hazard of falling off the tabletop. Content of the Utility Model

[0004] In order to overcome the above technical problems, the purpose of the utility model is to provide a built-in low-speed constant-temperature biological centrifuge to solve the problem that a single sealing ring is used between the centrifuge lid and the body as mentioned in the above background technique. When the lid covers the body, the sealing effect of the single sealing ring is poor, and the temperature inside the centrifuge is easily affected by the external environment.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A built-in low-speed constant-temperature biological centrifuge includes a low-speed constant-temperature centrifuge component group. The low-speed constant-temperature centrifuge component group includes a body part and an upper cover part. The body part is hinged to the upper cover part. A sealing component group is arranged at the top of the body part. The sealing component group is used to seal the body part and the upper cover part. The sealing component group includes a middle rubber ring. An inner rubber ring and an outer rubber ring are arranged outside the middle rubber ring. A fixed hoop and a movable hoop are arranged outside the outer rubber ring. Connecting plate one, connecting plate two and screw parts are arranged on the side of the fixed hoop. Anti-slip component groups are arranged on both sides of the body part. The anti-slip component groups are used to improve the stability of the body part.

[0007] Preferably: The axis lines of the middle rubber ring, the inner rubber ring and the outer rubber ring are the same, and the inner rubber ring and the outer rubber ring are both fixedly connected to the upper cover part.

[0008] Preferably, the middle rubber ring is fixedly connected to the top of the body member, the middle rubber ring contacts the inner rubber ring and the outer rubber ring, and the fixed hoop is fixedly connected to the top of the body member.

[0009] Preferably, one side of the fixed hoop and the moving hoop is connected by a rotating shaft, the moving hoop is in sliding contact with the top of the body member, the other side of the moving hoop is connected to the first connecting plate, the second connecting plate is connected to the fixed hoop, the screw member is connected to the second connecting plate through a threaded hole, the screw member contacts the first connecting plate through a through hole, and the diameter of the head of the screw member is smaller than the through hole.

[0010] Preferably, the anti-slip component group includes a sticking frame, one side of the sticking frame is provided with a connecting arm, one end of the connecting arm is connected with an end plate, and a bolt assembly is arranged inside the connecting arm.

[0011] Preferably, there are four groups of the anti-slip component groups, and the four groups of anti-slip component groups are symmetrically distributed on both sides of the body member.

[0012] Preferably, the sticking frame is connected to the body member, the sticking frame and the connecting arm are connected by a bolt assembly, and anti-slip gaskets are connected to the bottom of both the end plate and the connecting arm.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The built-in low-speed constant-temperature biological centrifuge is provided with a sealing component group. Currently, on the biological centrifuge with an internal low-speed constant-temperature mechanism, a single sealing ring is used between the centrifuge lid and the body. When the lid is covered on the body, the sealing effect of the single sealing ring is poor, the temperature inside the centrifuge is easily affected by the external environment, the load of the constant-temperature control system increases, and the temperature stability inside the equipment cannot be guaranteed, thereby affecting the samples. In the corresponding designed sealing component group, after placing the sample into the body member, close the upper cover member so that the upper cover member covers the body member. At this time, the middle rubber ring will be clamped between the inner rubber ring and the outer rubber ring. Then, by rotating the moving hoop, the first connecting plate connected to the moving hoop and the second connecting plate are brought into contact. Then, let the screw member pass through the through hole of the first connecting plate and connect it to the threaded hole of the second connecting plate. By tightening the screw member, the head position of the screw member will contact the first connecting plate, and the screw member will squeeze the fixed hoop, making the connection between the fixed hoop and the moving hoop stable. Due to the clamping of the fixed hoop and the moving hoop, the internal middle rubber ring, inner rubber ring, and outer rubber ring will be connected more tightly to each other, increasing the sealing performance between the body member and the upper cover member, preventing the temperature inside the centrifuge from being affected by the external environment, reducing the load of the constant-temperature control system, and improving the temperature stability inside the equipment;

[0015] 2. The built-in low-speed constant-temperature biological centrifuge is provided with an anti-slip component group. At present, the centrifuge body lacks a stable structure. When the centrifuge is placed on a relatively smooth tabletop for work, the centrifuge is prone to move during operation, posing a safety hazard of falling off the tabletop. In the corresponding designed anti-slip component group, when placed on a relatively smooth tabletop, by removing the bolt assembly and adjusting the angles of the connecting arm and the end plate, the anti-slip pads at the bottom of the connecting arm and the end plate can contact the tabletop. Subsequently, the connecting arm and the mounting frame are connected through the bolt assembly. Due to the functions of the connecting arm and the end plate, the friction between the low-speed constant-temperature centrifuge component group and the tabletop can be increased, achieving the effect of improving the working stability of the centrifuge and preventing it from sliding and displacing during operation.

The anti-slip component groups 03 are used to improve the stability of the body part 11.

[0024] The central axes of the middle rubber ring 21, the inner rubber ring 22 and the outer rubber ring 23 are the same. The inner rubber ring 22 and the outer rubber ring 23 are both fixedly connected to the upper cover part 12.

The screw member 28 is connected to the connecting plate two 27 through a threaded hole. The screw member 28 contacts the connecting plate one 26 through a through hole, and the head diameter of the screw member 28 is smaller than the through hole.

[0027] The anti-slip component group 03 includes a pasting frame 31. A connecting arm 32 is arranged on one side of the pasting frame 31. One end of the connecting arm 32 is connected with an end plate 33. A bolt assembly 34 is arranged inside the connecting arm 32.

[0030] Working principle: Currently, on a biological centrifuge with a built-in low-speed constant-temperature mechanism, a single sealing ring is used between the centrifuge lid and the body. When the lid is placed on the body, the sealing effect of the single sealing ring is poor. The temperature inside the centrifuge is easily affected by the external environment, increasing the load on the constant-temperature control system and unable to ensure the temperature stability inside the equipment, thus affecting the samples. In the corresponding designed sealing component group 02, after placing the sample into the body part 11, close the upper cover part 12 so that the upper cover part 12 covers the body part 11. At this time, the middle rubber ring 21 will be clamped between the inner rubber ring 22 and the outer rubber ring 23. Then, by rotating the moving hoop 25, the connecting plate one 26 and the connecting plate two 27 connected to the moving hoop 25 are made to contact. Then, let the screw part 28 pass through the through hole of the connecting plate one 26 and connect it to the threaded hole of the connecting plate two 27. By tightening the screw part 28, the head position of the screw part 28 will contact the connecting plate one 26, and the screw part 28 will squeeze the fixed hoop 24, making the connection between the fixed hoop 24 and the moving hoop 25 stable. Due to the clamping of the fixed hoop 24 and the moving hoop 25, the middle rubber ring 21, the inner rubber ring 22, and the outer rubber ring 23 inside will be connected more tightly to each other, increasing the sealing performance between the body part 11 and the upper cover part 12, avoiding the temperature inside the centrifuge from being affected by the external environment, reducing the load on the constant-temperature control system, and improving the temperature stability inside the equipment. Currently, there is a lack of a stable structure on the centrifuge body. When the centrifuge is placed on a relatively smooth tabletop for work, the centrifuge is prone to moving during operation and there is a safety hazard of falling off the tabletop. In the corresponding designed anti-slip component group 03, when placed on a relatively smooth tabletop, by removing the bolt assembly 34 and adjusting the angles of the connecting arm 32 and the end plate 33 so that the anti-slip pads at the bottom of the connecting arm 32 and the end plate 33 can contact the tabletop, and then connecting the connecting arm 32 and the sticker holder 31 through the bolt assembly 34. Due to the action of the connecting arm 32 and the end plate 33, the friction between the low-speed constant-temperature centrifuge component group 01 and the tabletop can be increased, achieving the effect of improving the working stability of the centrifuge and preventing it from sliding and displacing during operation.
