Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of detection equipment, especially relates to a four-position oscillation support. BACKGROUND

[0002] In sample detection, a lot of samples need to be shaken before detection. For example, in the detection of certain components in blood samples, such as platelet count, white blood cell classification, etc., sometimes the blood sample needs to be shaken to ensure uniform distribution of cells, so as to obtain accurate detection results. For blood samples using anticoagulants, shaking can help the anticoagulants to be evenly distributed, preventing blood from coagulating and affecting the detection results. For example, in the detection of formed elements in urine samples (such as red blood cells, white blood cells, epithelial cells, etc.), shaking the urine sample can help the components to be evenly distributed, avoiding inaccurate detection results due to sedimentation or aggregation. For urine samples with a large number of formed elements, shaking can make them more evenly distributed in the sample, improving the accuracy of detection.

[0003] During sample shaking operation, an oscillator can be used. The top driving end of the oscillator is provided with a support, and the tabletop of the oscillator is provided with a limiting frame. During operation, the limiting frame is first removed, or the limiting frame is adjusted to a higher position. After the sample tube is placed on the support, the limiting frame is installed or adjusted to a lower position, so that the limiting frame can limit the top of the sample tube, preventing the sample tube from falling off the support during shaking. Moreover, the disassembly and height adjustment of the limiting frame are relatively complex, and after the limiting frame is adjusted to a higher position, it is also more difficult to place and remove the sample tube subsequently.

[0004] In view of the above problems, the utility model aims to provide a four-position oscillation support, which aims to solve the above technical problems.

[0005] The utility model adopts the following technical scheme:

[0006] The four-position oscillation support comprises a chassis and a cross pressing plate. The bottom of the chassis is provided with a fixing part. Four groups of auxiliary frames are evenly arranged on the chassis. A guide cylinder is arranged at the center position of the chassis. A spring and a T-shaped guide rod are arranged in the guide cylinder. The spring is located above the end of the T-shaped guide rod. Wings are formed on both sides of each supporting arm of the cross pressing plate. A connecting cylinder is arranged at the center position of the cross pressing plate. The head end of the T-shaped guide rod is rotatably installed in the connecting cylinder. A quarter short groove is arranged on the side wall of the connecting cylinder. A locking pin is inserted into the short groove and fixed to the side wall of the head end of the T-shaped guide rod.

[0007] Further, a pair of planes are arranged on the side wall of the guide cylinder. A long groove is formed in the planes. An adjustable height position locking bolt is arranged in the long groove. A sliding groove is formed in the T-shaped guide rod. The locking bolt is inserted into the sliding groove. The spring is located between the locking bolt and the end of the T-shaped guide rod.

[0008] Furthermore, the wing plates on the cross-shaped pressure plate form a grid pattern.

[0009] Furthermore, the chassis has a recessed groove formed downwards opposite each auxiliary frame position.

[0010] Furthermore, the auxiliary frame includes four uprights and a ring rod connecting the top of the uprights.

[0011] The beneficial effects of this utility model are as follows: In this structure, the initial position of the cross pressure plate does not interfere with each auxiliary frame, which makes it convenient for the user to place the sample tube into the auxiliary frame, and then pull the cross pressure plate upward and rotate it 90 degrees. At this time, each sample tube is located directly below the end of each support arm of the cross pressure plate. After releasing the cross pressure plate, the top of the sample tube is pressed tightly. When it is necessary to remove the sample tube, the operation can be reversed. Therefore, the operation of this device is very simple and the limiting effect of the sample tube is also better. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0017] like Figures 1-3As shown, the four-position oscillation support provided by the embodiment includes a chassis 1 and a cross-shaped pressing plate 2, the chassis 1 has a fixing portion 3 at the bottom, four groups of auxiliary supports 4 are uniformly arranged on the chassis 1, a guide cylinder 5 is arranged at the center of the chassis 1, a spring 6 and a T-shaped guide rod 7 are arranged in the guide cylinder 5, the spring 6 is above the end of the T-shaped guide rod 7, wing plates 21 are downwardly formed at both sides of each supporting arm of the cross-shaped pressing plate 2, a connecting cylinder 22 is arranged at the center of the cross-shaped pressing plate 2, the head end of the T-shaped guide rod 7 is rotatably installed into the connecting cylinder 22, and a quarter short groove 23 is further arranged on the side wall of the connecting cylinder 22, and a locking nail 71 is inserted into the short groove 23 and fixed to the side wall of the head end of the T-shaped guide rod 7.

[0018] In the structure, the whole structure is installed on the top driving end of the oscillator through the fixing portion at the bottom of the four-position oscillation support, the driving end of the oscillator slightly vibrates in the horizontal range, and thus the oscillation driving of the four-position oscillation support is realized. The four groups of auxiliary supports are cross-shaped, and in the drawing, the auxiliary support 4 includes four vertical rods 41 and a ring rod 42 connected to the top of the vertical rods. The sample tube is directly placed in the auxiliary support 4, and in addition, the chassis 1 downwardly forms a sink 11 at the position opposite to each auxiliary support 4, so as to better limit the bottom of the sample tube.

[0019] In the initial state, the direction of the cross-shaped pressing plate is staggered with the four groups of auxiliary supports and does not interfere, and the bottom of the connecting cylinder 22 can contact the top of the guide cylinder 5. After the sample tube is placed, the cross-shaped pressing plate is pulled upward so that the height of the wing plate is equal to the top of the sample tube, and then the cross-shaped pressing plate is rotated by 90 degrees, at this time, each sample tube is located directly below the end of each supporting arm of the cross-shaped pressing plate, and after the cross-shaped pressing plate is released, the sample tube top is pressed by the cross-shaped pressing plate under the action of the spring. The wing plate can also limit the top of the sample tube. When the sample tube needs to be taken out, the reverse operation can be performed, that is, the cross-shaped pressing plate is pulled upward and is reversely rotated by 90 degrees and then is released. Therefore, the operation of the device is very simple, and the limiting effect of the sample tube is also good. In addition, it should be noted that in the structure, the cross-shaped pressing plate is rotated by 90 degrees through the quarter short groove and the locking nail for limiting control.

[0020] As a preferred structure, the wing plates 21 on the cross-shaped pressing plate 2 form a cross shape, which can improve the overall strength of the cross-shaped pressing plate 2.

[0021] In order to conveniently adjust the pressure of the cross pressing plate, the embodiment provides a specific structure, the side wall of the guide cylinder 5 is provided with a pair of planes 51, the plane 51 is provided with a through long slot 52, the long slot 52 is provided with a locking bolt 53 which can be adjusted in height position, the T-shaped guide rod 7 is provided with a sliding slot 72, the locking bolt 53 passes through the sliding slot 72, and the spring 6 is located between the locking bolt 53 and the end of the T-shaped guide rod 7. The locking bolt 53 can be a manual butterfly bolt, which is convenient to adjust. For example, when the position of the locking bolt 53 is adjusted downward and locked, the compression degree of the spring becomes larger, and the pressure of the cross pressing plate on the sample tube increases, so that the pressure adjustment of the cross pressing plate can be realized through the structure, and even different height sample tubes can be adapted.

[0022] The above merely describes the preferred embodiment of the utility model and is not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
