[0002] Molecular reagents are chemical or biological substances used in molecular biology research, biotechnology development, and clinical diagnostics. Currently, in some small laboratories and research institutions, due to limited funding and small reagent dispensing volumes, the dispensing equipment often uses manually adjustable needles to control costs. However, after manual adjustment, the needle spacing must be measured individually with calipers and the data recorded, a tedious and time-consuming process. Especially when there are a large number of needles, the measurement work significantly increases the operation time, seriously affecting experimental efficiency. Utility Model Content

[0003] The purpose of this invention is to address the problem that small laboratories and research institutions often use manually adjustable needle dispensing equipment due to budget and usage limitations, but the spacing measurement is cumbersome and easily slows down the experimental progress. This invention proposes a molecular reagent dispensing mechanism.

[0004] The technical solution of this utility model is as follows: a molecular reagent dispensing mechanism, including a fixed plate and a plurality of needles, and further including: an adjustment groove and a limiting groove that are interconnected on the fixed plate; an adjustment block that is slidably connected in the adjustment groove and corresponds to the needle and is fixedly connected to its end; a spring mechanism that is arranged between the adjustment blocks to make the spacing after adjustment the same; and a rotating mechanism installed at one end of the fixed plate to drive the spring mechanism to adjust.

[0005] Optionally, the rebound mechanism includes a rotating groove formed between the adjusting blocks. Each of the rotating grooves on the pair of adjusting blocks is provided with a spring of the same elastic force. A pair of first rotating rods are rotatably connected inside one of the rotating grooves, and a second rotating rod corresponding to the first rotating rods is rotatably connected inside the other rotating groove. A rotating groove is formed at the end of the second rotating rod near the first rotating rod. A rotating block inserted into the rotating groove is fixedly connected at the end of the first rotating rod near the second rotating rod. The connecting ends of the first rotating rod and the second rotating rod are rotatably connected by a rotating shaft.

[0006] Optionally, the outer wall of the adjusting block is also fixedly connected with a pair of limiting sliders that are engaged in the limiting groove.

[0007] Optionally, the rotating mechanism includes a spiral rod that is spirally connected to one end of the fixed plate, a support base that is fixedly connected to the outer wall of one of the adjusting blocks, one end of the spiral rod spirally passing through the adjusting groove and rotatably connected to the support base, and a knob that is fixedly connected to the other end of the spiral rod.

[0008] Optionally, the outer wall of the knob is provided with a plurality of grooves arranged in a circumferential array.

[0009] Optionally, each of the adjustment blocks is provided with a pointer at its top, and the upper surface of the fixing plate is provided with a scale for the pointer to point to.

[0010] Optionally, the end of the adjusting block furthest from the needle is fixedly connected to an infusion tubing.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This utility model utilizes the combination of structures such as adjustment groove, limit slide groove, adjustment block, spring mechanism and rotation mechanism. When it is necessary to adjust the spacing of multiple needles, simply turn the knob, and the knob drives the adjustment block to move the needles synchronously.

[0025] Example

[0026] like Figures 1 to 4As shown, the present invention proposes a molecular reagent dispensing mechanism, including a fixed plate 1 and several needles 201. The fixed plate 1 has an adjustment groove 11 and a limiting slide groove 12 that are interconnected. Adjustment blocks 2 corresponding to and fixedly connected to the ends of the needles 201 are slidably connected within the adjustment groove 11. One adjustment block 2 located at the starting point of the scale 31 is fixedly connected to the inner wall of the adjustment groove 11. The distance between all adjustment blocks 2 can be determined by observing the distance between the starting adjustment block 2 and the sequentially connected adjustment blocks 2, which is achieved by the force of the elastic spring 28. Adjustment blocks 2 corresponding to and fixedly connected to the ends of the needles 201 are slidably connected within the adjustment groove 11. A pair of limiting sliders 27, which engage with the limiting slide groove 12, are also fixedly connected to the outer wall of the adjustment block 2. The limiting sliders 27 engage with the limiting slide groove 12, thus restricting the adjustment block 2 to slide only at the same horizontal level, preventing tilting. An infusion tubing 202 is fixedly connected to the end of each adjustment block 2 away from the needle 201.

[0027] Among them, such as Figures 3 to 4 As shown, a spring-loaded mechanism is provided between the adjusting blocks 2 to ensure that the spacing after adjustment is the same. The spring-loaded mechanism includes a rotating groove 21 formed between the adjusting blocks 2. Each rotating groove 21 on a pair of adjusting blocks 2 has a spring 28 with the same elastic force in its middle. The spring 28 provides feedback with the same elastic deformation force, restricting the movement of the adjusting blocks 2 and causing them to tend to be evenly distributed under the action of force. Even if there are slight disturbances or errors, the elastic buffer of the spring 28 can adaptively adjust and compensate for the differences through deformation, ultimately ensuring that the spacing of the components is the same after adjustment. A pair of first rotating rods 22 are rotatably connected inside one of the rotating grooves 21, and a second rotating rod 24 corresponding to the first rotating rods 22 is rotatably connected inside the other rotating groove 21. The second rotating rod 24 is rotatably connected to the first rotating rod 22, and its function is to further ensure that the multiple adjusting blocks 2 can only be adjusted and slid on the same horizontal level. The second rotating rod 24 has a rotating groove 25 at one end near the first rotating rod 22. The first rotating rod 22 is fixedly connected to a rotating block 23 inserted into the rotating groove 25 at one end near the second rotating rod 24. The connecting ends of the first rotating rod 22 and the second rotating rod 24 are rotatably connected by a rotating shaft 26.

[0028] In addition, such as Figures 1 to 3 As shown, a rotating mechanism for adjusting the drive spring mechanism is installed at one end of the fixed plate 1. The rotating mechanism includes a spiral rod 204 that is spirally connected to one end of the fixed plate 1. A support base 203 is fixedly connected to the outer wall of one of the adjusting blocks 2. One end of the spiral rod 204 spirally passes through the adjusting groove 11 and is rotatably connected to the support base 203. A knob 205 is fixedly connected to the other end of the spiral rod 204.

[0029] It is worth noting that, such as Figure 3As shown, multiple grooves 206 arranged in a circular array are provided on the outer wall of the knob 205. The function of the grooves 206 is to increase the friction when the knob 205 is manually rotated, so as to prevent the knob 205 from sliding when manually rotated.

[0030] Furthermore, such as Figures 1 to 3 As shown, each adjusting block 2 has a pointer 3 at its top. The pointer 3 is used to point to the scale 31, thereby indicating the amount of movement of the corresponding adjusting block 2. The upper surface of the fixed plate 1 has a scale 31 for the pointer 3 to point to. The scale 31 refers to the measuring tool of the measuring instrument (e.g., a ruler), which is a mark or line divided for accurate measurement and representation of values.

[0031] In this embodiment, when using a molecular reagent dispensing mechanism, such as Figure 1 As shown, simply turn knob 205 manually. Knob 205 drives the rotation of screw rod 204. Since screw rod 204 is screwed to fixed plate 1, the end of screw rod 204 away from knob 205 pushes support base 203 to move, and support base 203 in turn pushes the corresponding adjusting block 2 to move. However, through the springs 28 with the same elastic force set between the adjusting blocks 2, each adjusting block 2 is subjected to equal and consistent force. During adjustment, the equal elastic force balances the force on the adjusting blocks 2, preventing displacement deviation of a component due to uneven force. When an external force pushes or pulls the adjusting block 2, each spring 28 provides feedback with the same elastic deformation force, limiting the movement of the adjusting blocks 2 and making them tend to be evenly distributed under the action of force. Even if there are small disturbances or errors, the elastic buffer of spring 28 can adaptively adjust, compensating for differences through deformation, and ultimately ensuring that the spacing between components is the same after adjustment, which is convenient, quick, and efficient. As the distance between the adjusting blocks 2 increases or decreases, the rotating block 23 at the end of the first rotating rod 22 rotates within the rotating groove 25 at the end of the second rotating rod 24, supported by the rotating shaft 26, ensuring that the adjusted adjusting blocks 2 are at the same horizontal height. Finally, the limiting slider 27 ensures the stable operation of the first rotating rod 22, the rotating block 23, the second rotating rod 24, the rotating groove 25, and the rotating shaft 26.

[0032] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
