In particular, for those drugs or reagents that are difficult to dissolve, such as erythromycin staining solution, bacterial endotoxin standard, etc., multiple reagents can be easily mixed at one time. Background Art
[0002] Driven by the rapid development of science and technology and social progress, the efficiency of all walks of life is constantly improving, both actively and passively. However, many of the most basic places are still stagnant in the previous state, especially in key and easily overlooked places such as production quality inspection or scientific research laboratories. In the past, when mixing reagents with a micro-vortex mixer, only one reagent could be mixed at a time, and it was placed on the bracket of the micro-vortex mixer. During the mixing process, the reagent tube was easy to tilt and the liquid medicine spilled. Sometimes, for safety, it could only be held by hand to complete the reagent mixing process. This is not only labor-intensive for professionals, but also very inefficient, and the mixing effect is difficult to guarantee. Therefore, it is particularly important to find a device that can improve labor intensity, liberate the hands of professionals, and improve work efficiency. In particular, it is necessary to develop a device that can mix multiple reagent tubes at a time, and the mixing process will not loosen or tilt, and does not require the intervention of professionals.

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0021] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0022] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0023] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0024] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0025] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
[0026] like Figures 1 to 5 As shown, an embodiment of the utility model discloses a multi-tube reagent synchronous mixing locking and fixing device, comprising a bracket, a multi-tube synchronous fixing device 1, a hollow column 3, a continuous flexible pressing handrail 4 and a half-grip anti-slip clamping device 6, wherein the multi-tube synchronous fixing device 1 is at least two-layered, and in this embodiment is two-layered, which can prevent tilting and overflowing during the mixing process, and the test tube 2 is inserted into the rubber hole on the outside of the multi-tube synchronous double-layer fixing device 1 from the top, and the multi-tube synchronous fixing device 1 is installed at the bottom of the hollow column 3, and a continuous flexible pressing handrail 4 sleeved on the hollow column 3 is arranged between the two layers, and a convex soft rubber 4-2 pressed on the middle part of the test tube 2 is arranged at the end of the continuous flexible pressing handrail 4, and the upper part of the hollow column 3 is fixed to the bracket 5 by the half-grip anti-slip clamping device 6, and the half-grip anti-slip clamping device 6 is used to adjust the relative height between the hollow column 3 and the bracket, thereby adjusting the bottom of the test tube to be pressed tightly on the upper working area of the micro vortex mixer. The hollow column 3 is moved up and down by the half-grip anti-slip clamping device 6, so that the bottom of the test tube 2 is pressed tightly against the upper working area of the micro vortex mixer 7. At this time, the hollow column 3 is fixed on the U-shaped bracket 5 by the half-grip anti-slip clamping device 6, and part of the deadweight of the U-shaped bracket 5 also acts on the upper working area of the micro vortex mixer 7 together with the test tube.
[0027] The test tube 2 is inserted into the rubber hole outside the multi-tube synchronous double-layer fixing device 1 from the top. Due to its upper and lower two-layer structure, the vertical stability of the test tube 2 is greatly improved, which can prevent tilting and overflowing during the mixing process, free the hands of the staff, and enhance the stability of the mixing process.
[0028] The multi-tube synchronous double-layer fixing device 1 is fixed to the bottom of the hollow column 3 by bolts, and bolts are arranged above and below the continuous flexible clamping handrail 4, which is self-locked by double bolts to limit the upper and lower parts so that it can rotate around the hollow column 3.
[0029] The continuous flexible pressing handrail includes an arm 4-1, a convex soft rubber 4-2, a rotating sleeve 4-3, a reset column 4-4, and a reset spring 4-5. The rotating sleeve 4-3 is sleeved on the outside of the hollow column 3. The rotating sleeve 4-3 is provided with notches for installing the reset column at preset angles based on the number of arm 4-1. The reset column 4-4 is fixed on the hollow column 3 through the reserved notch of the rotating sleeve 4-3. One end of several arm 4-1 is fixed on the rotating sleeve 4-3, and the other end is a semicircular socket structure matching the test tube, in which a convex soft rubber is arranged. Because it is a convex surface, its anti-slip performance is increased. Because it is made of soft rubber, the arm 4-1 The pressure acts on the test tube 2 without being damaged; the armrest 4-1 can rotate back and forth around the hollow column 3 with the rotating sleeve 4-3, and the rotation amplitude is limited by the length of the notch opened by the rotating sleeve 4-3 for the reset column 4-4 fixed on the hollow column 3. The length of the notch is related to the size of the fixed test tube or container. In this embodiment, four test tubes are taken as an example, and the notch requirement is to rotate 15° around the center of the hollow column 3; the root of some of the armrests is connected to one end of the reset spring, and the other end of the reset spring is connected to the reset column. Specifically, in this embodiment, there are two armrests 4-1 connected to the reset spring 4-5, and the other two are connected to the root of the armrest 4-1 and the tensioning wire rope 4-6.
[0030] The continuous flexible clamping armrest is connected with a pressure regulating device, so that the pressure holding force of the continuous flexible clamping armrest on the middle of the test tube is adjustable, and the clamping strength can be adjusted by the rotating tightening cap 4-8 of the continuous flexible clamping armrest 4, and the clamping strength is adjusted according to the characteristics of the liquid to be mixed, so as to achieve the best mixing effect. Specifically, it includes a tightening wire rope 4-6, a tightening flexible spring 4-7 and a rotating tightening cap 4-8, the tightening wire rope is connected to the armrest that is not connected to the reset spring, and the other end of the tightening wire rope passes through the reserved notch of the rotating sleeve and the reserved hole of the hollow column, passes through the hollow middle of the hollow column and comes out at its uppermost part, and is connected to one end of the tightening flexible spring, and the other end of the tightening flexible spring is connected to the central rotating ring in the rotating tightening cap. The rotating tension cap 4-8 in the cross-sectional view of the multi-tube reagent synchronous mixing and locking device corresponds to the position of the armrest 4-1 in the figure. When the rotating tension cap 4-8 rotates and moves downward, under the pulling force of the reset spring 4-5, the armrest 4-1 gradually leaves the test tube 2 with the convex soft rubber 4-2, and the rotating tension cap 4-8 continues to move downward until the armrest 4-1 is reset, and the test tube is taken out and waits for the next use.
[0031] The half-grip anti-skid clamping device 6 is composed of a pressing concave slider 6-1, an anti-skid rubber 6-2, a hollow push-pull seat 6-3, a disc-type retaining ring 6-4, a pressing push-pull rod 6-5, a rotary transmission cap 6-6, a guide key 6-7, and a guide key slot 6-8. The clamping concave slider 6-1 is glued and fixed to the anti-skid rubber 6-2, which contacts a part of the outer surface of the hollow column 3, while the other outer surfaces of the hollow column 3 at the same height are in contact with the anti-skid rubber glued and fixed in the groove of the U-shaped bracket. The other end (plane) of the clamping concave slider 6-1 is bolted to the hollow push-pull seat 6-3. The center of the hollow push-pull seat 6-3 is provided with a hole. One end of the clamping push-pull rod 6-5 passes through the center hole of the hollow push-pull seat 6-3. Disc-type retaining rings 6-4 are respectively used on both sides of the center hole of the hollow push-pull seat 6-3 to clamp the clamping push-pull rod 6-5. The other end of the clamping push-pull rod 6-5 is fixed to the center point of the rotating transmission cap 6-6. The rotating transmission cap 6-6 is connected to the end of the U-shaped bracket 5 through a thread. The rotary transmission cap 6-6 drives the clamping push-pull rod 6-5 to make concentric rotational motion through the thread, so that the clamping push-pull rod 6-5 drives the clamping concave slider 6-1 to move along the crossbeam direction of the U-shaped bracket 5. Guide keys 6-7 are respectively provided on both sides of the clamping concave slider 6-1, and a guide key groove 6-8 is provided in the cavity of the U-shaped bracket 5. With the cooperation of the guide key 6-7 and the guide key groove 6-8, the clamping concave slider 6-1 can only move along the direction of the guide key groove 6-8, ensuring that the groove direction of the clamping concave slider 6-1 is always positive to the groove of the U-shaped bracket 5, thereby ensuring that the hollow column 3 is always in the vertical direction.
[0032] The rotary transmission cap 6-6 and the clamping push-pull rod 6-5 make concentric rotational motion. In addition, the clamping push-pull rod 6-5 passes through the center hole of the hollow push-pull seat 6-3 and is fixed front and back by a disc-type retaining ring 6-4, allowing it to rotate freely, cleverly converting the rotational movement of the thread into a simple push-pull movement, and simultaneously realizing the clamping effect of the push-pull force on the hollow column 3 and the locking effect of the threaded connection between the rotary transmission cap 6-6 and the end of the U-shaped bracket 5.
[0033] The specific use process of this embodiment is as follows: the inspector or scientific researcher first holds the hollow column 3 with his hand, and rotates the rotary transmission cap 6-6 of the half-grip anti-slip clamping device 6 outward, so that the clamping push-pull rod 6-5 moves with the clamping concave slider 6-1 along the direction of the guide keyway 6-8 to loosen the hollow column 3, and as the rotary transmission cap 6-6 continues to rotate, it moves out of the hollow column 3; rotate the rotary tensioning cap 4-8 at the top of the hollow column 3 inward, the rotary tensioning cap 4-8 moves downward, and the tensioning flexible spring 4-7 begins to shorten. As the rotary tensioning cap 4-8 continues to rotate, under the action of the reset spring 4-5, the armrest 4-1 and the rotating sleeve 4-3 begin to rotate around the hollow column 3, and the wire rope 4-6 is tightened downward. The armrest 4-1 rotates with the convex soft rubber 4-2 away from the test tube until it is reset. At this time, the multiple test tubes 2 to be mixed can be inserted one by one from the top into the rubber holes outside the multi-tube synchronous double-layer fixing device 1. Because the rubber itself has a certain elasticity, the introduced test tubes 2 will not move under the condition of self-weight, and the multiple test tubes 2 are kept at the same height as much as possible. When the test tubes 2 are placed in place, the rotary tensioning cap 4-8 at the top of the hollow column 3 is rotated outward, and the rotary tensioning cap 4-8 moves upward. At the same time, the tensioning flexible spring 4-7 begins to lengthen, and the tensioning wire rope 4-6 will resist the reset spring 4-5 through the armrest 4-1 and the rotating sleeve 4-3. With the continuous rotation of the rotary tensioning cap 4-8, the force of the reset spring 4-5 is overcome, so that the armrest 4-1 with the convex soft rubber 4-2 rotates toward the test tube until it is pressed and meets the strength required by the mixed liquid.
[0034] Place the hollow column 3 in the relative recess between the U-shaped bracket 5 and the half-grip anti-skid clamping device 6, and naturally sit on the micro-vortex mixer 7. After it is in place, press the hollow column 3 downward with appropriate force to make the test tube 2 fully contact with the micro-vortex mixer 7, turn the rotary transmission cap 6-6 of the half-grip anti-skid clamping device 6 inward, and let the pressing push-pull rod 6-5 move the pressing concave slider 6-1 along the direction of the guide key groove 6-8, close to the hollow column 3, until it is pressed. At this time, the multi-tube reagent synchronous mixing locking and fixing device has been fixed, and the micro-vortex mixer 7 can be started to start mixing. After mixing, reverse the operation, operate the half-grip anti-skid clamping device 6 to loosen the hollow column 3, and then operate the continuous flexible pressing handrail 4 to loosen the test tube 2, and take out the test tube 2 to complete this operation.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
