Description

Technical Field

[0001] This utility model relates to the technical field of drying needle installation equipment, specifically to a convenient installation structure for drying needles in biochemical equipment. Background Technology

[0002] The fully automated seminal plasma analyzer mainly detects the content of various biochemical indicators in seminal plasma samples. It works by adding a mixture of sample and reagent to a cuvette inside the reaction plate, where a chemical reaction occurs in a constant-temperature incubator. Based on the characteristic absorption spectra of substances in the ultraviolet and visible light regions and the principle of Lambert-Beer's law, the analytes in the seminal plasma are finally quantitatively analyzed using the molar absorptivity method.

[0003] The drying needle in the cuvette cleaning mechanism is a crucial component of the fully automated biochemical analyzer. Its ability to absorb moisture after cleaning the cuvettes directly affects the accuracy of subsequent tests. Because the original mounting plate structure did not provide sufficient space for the drying head to pass through, it was necessary to first remove the drying head, install the drying needle tube, and then reinstall the drying head onto the tube. This process could affect the reliability of the connection between the drying head and the needle tube, impacting the durability of the drying needle. Therefore, an improved installation process is needed. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a convenient installation structure for drying needles in biochemical equipment. This solves the problem that in the prior art, when installing drying needles using a mounting plate structure, it is necessary to first remove the drying head, install the drying needle tube, and then reinstall the drying head onto the drying needle tube, which can easily affect the durability of the drying needle.

[0005] A convenient installation structure for a drying needle in a biochemical device includes a mounting plate and a drying needle; the drying needle includes a drying needle tube and a drying head installed at the bottom of the drying needle tube;

[0006] The mounting plate is provided with a drying needle mounting hole and a drying head transfer hole. A drying needle tube transfer channel is provided between the drying needle mounting hole and the drying head transfer hole, allowing the drying needle tube to move from the drying head transfer hole into the drying needle mounting hole through the drying needle tube transfer channel.

[0007] Furthermore, the drying needle mounting hole is a rectangular through hole.

[0008] Furthermore, the drying needle also includes a main body sleeved on the drying needle tube, the main body being spaced apart from the drying head, and the outer diameter of the main body being adapted to the inner diameter of the drying needle mounting hole.

[0009] Furthermore, it also includes cleaning needles, and the mounting plate is also provided with cleaning needle mounting holes for mounting the cleaning needles.

[0010] Furthermore, the top of the mounting plate is provided with limiting posts, and a limiting groove is formed between adjacent limiting posts. The cleaning needle and the drying needle are connected to a flange on the outside, and one end of the flange is inserted into the limiting groove.

[0011] Furthermore, a limiting plate is provided on the upper side of the mounting plate, and the two ends of the limiting plate are detachably connected to the mounting plate.

[0012] Furthermore, the limiting plate has a limiting hole on one side near the cleaning needle or the limiting needle, and a limiting hole channel is provided on one side of the limiting hole to facilitate the installation of the cleaning needle or the limiting needle.

[0013] Furthermore, the width of the drying needle tube transfer channel is smaller than the outer diameter of the main body.

[0014] Beneficial effects: After the drying head is installed, the drying needle tube moves downward through the drying head transfer hole. Once the drying head has completely passed through the drying head transfer hole, the drying needle tube is moved into the drying needle mounting hole through the drying needle tube transfer channel to complete the installation of the drying needle. The entire process does not require disassembling the drying head and then connecting the drying head and the drying needle tube, which avoids the problem of durability loss caused by disassembling the drying head and extends the service life of the drying needle.

For ease of explanation, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0023] It should be noted that the embodiments and features involved in the embodiments of this utility model can be combined with each other without conflict. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] like Figures 1-5 The present invention relates to a convenient installation structure for a drying needle in a biochemical device, comprising a mounting plate 1 and a drying needle 2; the drying needle 2 includes a vertically arranged drying needle tube 201 and a drying head 203 sleeved on the bottom of the drying needle tube 201;

[0025] The mounting plate 1 has a drying needle mounting hole 101 for mounting the drying needle 2 and a drying head transfer hole 103 for the drying head 203 to pass through. A drying needle tube transfer channel 104 communicating with the drying needle mounting hole 103 is provided on one side of the drying head transfer hole 103, allowing the drying needle tube 201 to move from the drying head transfer hole 103 into the drying needle mounting hole 101 via the drying needle tube transfer channel 104. The drying head 203 has a through hole for the drying needle tube 201 to pass through; the diameter of this through hole is slightly smaller than the outer diameter of the drying needle tube 201 to ensure a secure connection between the drying needle tube 201 and the drying head 203.

[0026] In this embodiment, the drying head 203 is installed at the bottom of the drying needle tube 201. The drying head 203 is inserted downward into the drying head transfer hole 103 and then moved downward. After the drying head 203 is completely removed from the drying head transfer hole 103, the movement stops. The drying needle tube 201 is moved into the drying needle mounting hole 101 through the drying needle tube transfer channel 104 to complete the transfer of the drying needle 2. Finally, the installation of the drying needle 2 is completed. The entire installation process avoids the disassembly of the drying head 203, thereby avoiding the problem of durability loss caused by disassembling the drying head 203 and extending the service life of the drying needle 2.

[0027] The inner contour of the drying head transfer hole 103 is adapted to the outer contour of the drying head 203, and the drying head transfer hole 103 is a rectangular through hole.

[0028] In this embodiment, the inner contour of the drying head transfer hole 103 is adapted to the outer contour of the drying head 203, which facilitates the positioning and transfer of the drying head 203.

[0029] The drying needle 2 also includes a main body 202 sleeved on the drying needle tube 201, with the main body 202 spaced apart from the drying head 203. The width of the transfer channel of the drying needle tube 201 is smaller than the outer diameter of the main body 202, which is used to restrict the movement of the main body 202 toward the transfer hole 103 of the drying head.

[0030] In this embodiment, the drying needle tube 201 between the main body 202 and the drying head 203 is used to transfer the drying needle 2 through the drying needle tube transfer channel 104. After the drying needle 2 is moved through the drying needle tube transfer channel 104, the drying needle 2 moves downward and the main body 202 is inserted into the drying needle mounting hole 101. The main body 202 is made of elastic material, and the outer diameter of the main body 202 is slightly larger than or equal to the outer diameter of the drying needle mounting hole 101. This is to facilitate the contact between the side of the main body 202 and the side of the drying needle mounting hole 101, and to prevent the drying needle 2 from shaking inside the drying needle mounting hole 101. The outer diameter of the main body 202 is larger than the distance between the two ends of the drying needle tube transfer channel 104, so as to prevent the main body 202 from moving into the drying head transfer hole 103 through the drying needle tube transfer channel 104.

[0031] The mounting plate 1 is also provided with a cleaning needle mounting hole 102 for mounting the cleaning needle 3.

[0032] In this embodiment, the cleaning needle mounting hole 102 is provided for mounting the cleaning needle 3.

[0033] The top of the mounting plate 1 is provided with a limiting post 105, and a limiting groove is formed between adjacent limiting posts 105. A flange 204 is sleeved on the outside of the cleaning needle 3 and the drying needle 2, and one end of the flange 204 is inserted into the limiting groove.

[0034] In this embodiment, a flange 204 is sleeved on the outer side of the main body 202 of the drying needle 2; the outer sides of the drying needle 2 and the cleaning needle 3 are connected by the flange 204, one end of the flange 204 is inserted into the limiting groove, and the limiting posts 105 on both sides of the limiting groove restrict the flange 204 in the horizontal direction to prevent the cleaning needle 3 and the drying needle 2 from rotating and moving horizontally; at the same time, the flange 204 is also used to restrict the cleaning needle 3 and the drying needle 2 in the resin direction, and the contact between the flange 204 and the top of the mounting plate 1 prevents the cleaning needle 3 and the drying needle 2 from sliding downward.

[0035] The mounting plate 1 has through holes at both ends for screws to pass through. A limiting plate 4 is provided on the upper side of the mounting plate 1, and the bottom surfaces of both ends of the limiting plate 4 are detachably connected to the mounting plate 1 by screws. A limiting hole 401 for mounting the cleaning needle 3 or drying needle 2 is provided on the side of the limiting plate 4 near the cleaning needle 3 or drying needle 2. A limiting hole channel 402 is provided on one side of the limiting hole 401, through which the needle tube of the drying needle 201 or the needle tube of the cleaning needle 3 passes, facilitating the movement of the cleaning needle 3 or drying needle 2 into the mounting hole. The cleaning needle 3 and drying needle 2 are existing technologies.

[0036] Working principle: The drying needle 2 and cleaning needle 3 are pre-assembled. The cleaning needle 3 is installed in the cleaning needle mounting hole 102 of the mounting plate 1. The flange 204 connected to the outside of the cleaning needle 3 abuts against the top surface of the mounting plate 1, and one end of the flange 204 is inserted into the corresponding limiting groove. The end of the drying needle 2 with the drying head 203 is moved downward from above the drying head transfer hole 103 until the drying head 203 is disengaged from the drying head transfer hole 103. Then the drying needle 2 is moved horizontally, and the drying needle tube 201 passes through the drying needle tube transfer channel 104 and moves into the drying needle mounting hole 101. Then the drying needle 2 moves downward. One end of the flange 204 sleeved on the drying needle tube 201 moves downward along the limiting groove until the flange 204 abuts against the top surface of the mounting plate 1. Then the top of the cleaning needle 3 and the drying needle 2 are installed in the limiting hole 401 on the limiting plate 4. The two ends of the limiting plate 4 are connected to the two ends of the mounting plate 1 by screws or rivets.
