Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a bearing mounting mechanism. Background Technology

[0002] In the reagent tray of a chemiluminescence analyzer, a small lever bearing is installed inside the tray to support the rotation of the magnetic bead bottle in the reagent kit in order to mix the magnetic beads in the luminescence detection reagent. The mixing of the magnetic bead reagent is achieved by the rotation of the magnetic bead bottle. The existing bearing is mainly installed by a press, which can only put in and press one bearing at a time. This is inefficient and easy to press it out of place, which may cause the reagent tray to be scrapped or the movement of the small gear for mixing the magnetic beads to be uneven, resulting in abnormal noise, or even affecting the mixing effect of the magnetic beads.

Detailed Implementation

[0024] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figure 1-3As shown, a bearing mounting mechanism includes a clamping mechanism for providing pressure when clamping the bearing; a plurality of pressure head columns 1 mounted on the clamping mechanism for clamping the bearing; and a support mechanism for mounting the clamping mechanism.

[0026] This invention uses a clamping mechanism to provide downward pressure to clamp the bearings. Multiple pressure head columns 1 can simultaneously clamp multiple bearings into place each time, which can greatly save manpower and improve assembly accuracy and efficiency.

[0027] The support mechanism includes a base plate 2, a column 3 mounted on the base plate 2, and a tension spring suspension 4 mounted on the column 3.

[0028] The clamping mechanism includes a cam 5 rotatably mounted on the column 3 and a pressure plate frame 6 slidably mounted on the column 3; the top of the pressure plate frame 6 is connected to a tension spring suspension 4 via a tension spring, the tension spring provides a buffer force for the pressure plate frame 6 to prevent the pressure plate frame 6 from falling due to its own weight; multiple pressure columns 1 are mounted on the pressure plate frame 6, and a ratchet 7 is provided on one side of the pressure plate frame 6; the cam 5 is connected to the ratchet 7 for transmission, and is used to drive the ratchet 7 to move up and down, thereby driving the pressure plate frame 6 to move up and down, providing pressure when the pressure columns 1 clamp the bearing.

[0029] Furthermore, a guide rail 8 is provided on the column 3, and the pressure plate frame 6 is slidably mounted on the guide rail 8 via a slider 9; the ratchet 7 is fixedly mounted on one side of the slider 9.

[0030] The top of the ratchet 7 is provided with a guide wheel plate 10; the top of the guide wheel plate 10 is provided with a guide wheel 11; the outer ring of the cam 5 is tangent to the guide wheel 11, and the rotation of the cam 5 drives the ratchet 7 to move up and down along the guide rail 8, thereby driving the pressure head plate frame 6 to move up and down.

[0031] This invention uses the tangency of the outer ring of the cam with the guide wheel. When the bearing is pressed, the change in the outer diameter of the cam causes the pressure head plate to move downward, thereby driving the pressure head column to press the bearing into place.

[0032] Furthermore, a first handle 12 is fixed on the cam 5 for the operator to drive the cam 5 to rotate; a second handle 13 is rotatably installed on the end of the first handle 12 away from the cam 5, which can lengthen the lever arm and reduce the manual force required for clamping.

[0033] Furthermore, a first support frame 14 is slidably provided inside the base plate 2 along the length direction of the base plate 2, and can extend and retract along the length direction of the base plate 2; a second support frame 15 is rotatably installed on the base plate 2 on both sides of the first support frame 14, and can be extended or retracted relative to the base plate 2.

[0034] Furthermore, the first support frame 14 is installed in the slide groove below the base plate 2, and is limited by spring plungers on the side. When pressing the inner ring bearing of the reagent tray, it can be pulled out to the limited position for operation, and can be returned to the base plate 2 after completion. The second support frame 15 is rotatably installed on the base plate 2. When pressing the outer ring bearing of the reagent tray, it can be unfolded to the maximum position on both sides, and can be rotated back to both sides of the base plate 2 after completion.

[0035] Furthermore, the pressure plate frame 6 is provided with two rows of pressure head columns 1, namely inner ring pressure head columns 16 and outer ring pressure head columns 17; the inner ring pressure head columns 16 are aligned with the inner ring of the reagent tray and are used to press the bearing on the inner ring reagent tray, and the outer ring pressure head columns 17 are aligned with the outer ring of the reagent tray and are used to press the bearing on the outer ring reagent tray; each row of pressure head columns is provided with multiple columns.

[0036] A pad 18 is provided on the base plate corresponding to the inner ring pressure head 16 and the outer ring pressure head 17; the inner ring of the reagent tray is placed on the support surface formed by the first support frame 14 and the pad 18, which facilitates the inner ring pressure head 16 to press the bearing. The outer ring of the reagent tray is placed on the support surface formed by the second support frame 15 and the pad 18, which facilitates the outer ring pressure head 17 to press the bearing.

[0037] Furthermore, a lever 19 is rotatably mounted on the post 3 on one side of the ratchet 7, and a lever spring 20 is fixed on the post 3 below the lever 19 to tighten the lever 19; the ratchet 7 is configured with a toothed structure, and the front end of the lever 19 can be engaged with the ratchet 7.

[0038] With the above-described structure, after the bearing is clamped, even if the operator removes the handle, the tension spring will pull the pressure head plate 6 upward due to its elasticity. However, due to the presence of the lever 19, the one-way teeth of the ratchet 7, in conjunction with the lever 19, ensure that the pressure head plate 6 can only move downward in one direction, preventing the pressure head plate 6 from suddenly sliding upward and accidentally injuring the operator. When the pressure head plate 6 needs to be reset, the lever 19 can be rotated, and then the cam 5 can be slowly rotated, causing the tension spring to pull the pressure head plate 6 upward slowly.

[0039] Furthermore, the lower end of the pressure head column 1 is designed with a plane equal to the diameter of the outer ring of the bearing, so that the bearing can move horizontally downwards to accurately enter the hole and reach the desired position.

[0040] This utility model's bearing mounting mechanism is used for the bearing mounting and clamping of the mixing gears of the inner and outer disks of the reagent tray in a chemiluminescence analyzer. It ensures the vertical installation and correct positioning of the bearings, thereby enabling the magnetic beads to be smoothly mixed during the reagent kit operation. This plays a crucial role in improving production efficiency and subsequent instrument performance.

[0041] This invention uses a cam to provide downward pressure to clamp the bearings, and can clamp multiple bearings into place at the same time, which can greatly save manpower and improve assembly accuracy and efficiency.

[0042] This utility model has a simple structure, is highly operable, and ensures accurate and efficient bearing assembly and clamping. It can press-fit bearings of different outer diameter reagent trays, exhibiting strong compatibility. The handle of this utility model features a long and short arm folding design, which can maximize manpower savings. The lower support structure of this utility model can be retracted and extended, saving handling and storage space.

[0043] The above are merely embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model shall be included within the scope of the claims of this utility model pending approval.
