Description

A vortex mixer test tube fixing device

technical field

The utility model belongs to the field of laboratory appliances, in particular to a test tube fixing device for a vortex mixer.

Background technique

The laboratory vortex mixer often does not have a special test tube fixing device, and the user needs to hold the test tube when using it. However, laboratory mixing often takes a long time, so it is necessary to design a device that can fix the test tube.

In the prior art, there is a device for fixing test tubes on a vortex mixer. The device includes a bracket and a cylinder. The cylinder is provided with a groove with a diameter larger than that of the test tube, and the test tube is placed in the groove. This device solves the problem of having to hold the test tube to a certain extent, but there is only one cylinder on each support in the device, and only one test tube can be fixed at a time, which cannot meet the needs of simultaneous mixing; moreover, the test tube is not completely fixed, There is no blocking device at the top, and when the vortex mixer is vigorously moving, the liquid in the test tube is likely to splash out, and more seriously, the test tube will be broken. In addition, the position of the bracket cannot be adjusted, and the use in the laboratory will be limited by the position.

Utility model content

In view of the above-mentioned prior art, the utility model solves the technical problems that the liquid in the test tube is easy to splash, the test tube is easily broken, only one test tube can be mixed at a time, and the position of the bracket cannot be adjusted.

In order to achieve the above purpose, the technical solution adopted by the utility model is: provide a test tube fixing device for a vortex mixer, including a bracket and a test tube cover; the bracket includes a base, and a rotatable vertical bar is arranged on the base, and There is a horizontal bar, which is movably connected with the vertical bar; the test tube cover includes a slider and a rubber sleeve, the rubber sleeve is cylindrical, and its upper end is sealed, and the rubber sleeve is connected with the slider through an elastic rod; the slider is movably installed on the horizontal bar .

On the basis of the above technical solutions, the utility model can also be improved as follows.

Further, the bottom of the slider is provided with an arc-shaped through groove, and the radius of curvature of the arc-shaped through groove is slightly smaller than the radius of the crossbar; the slider is clamped on the crossbar through the arc-shaped through groove.

Further, the length of the rubber sheath is 1/4-1/3 of the length of the test tube.

Further, there is a notch at the lower end of the rubber sheath, and the notch accounts for 1/4-1/3 of the length of the rubber sheath.

Further, the cross bar is installed on the vertical bar through the lifting sliding sleeve.

Further, there is at least one test tube cover.

The beneficial effects of the utility model are:

1. The horizontal bar can move up and down along the vertical bar and rotate around the vertical bar. At the same time, the test tube cover can slide on the horizontal bar. Therefore, by adjusting the position of the horizontal bar on the vertical bar and the position of the slider on the horizontal bar, you can The hanging sleeve can reach any position on the working surface of the vortex mixer without being restricted by the position of the test tube fixing device, so the use is more flexible.

2. The test tube cover is clamped on the cross bar through the slider, which is convenient for disassembly and assembly, and the position of the slide block on the cross bar can be adjusted by applying a lateral force, thereby adjusting the position of the test tube cover, which is easy to operate. Moreover, multiple test tube sets can be snapped on the cross bar, and the test tubes installed in different test tube sets can be placed in the corresponding trays by adjusting the position of the cross bar and the slider, so that multiple test tubes can be mixed at the same time, and the mixing time is shortened. Mixing efficiency is improved.

3. Due to the elasticity of the rubber sleeve, it can fit test tubes of different specifications, which expands the scope of use of the device, and the upper end of the rubber sleeve is sealed. When working, even if the vortex mixer vibrates violently, the liquid in the test tube will not splash out. . The rubber sheath is connected with the slide block through an elastic rod, which can buffer most of the external force and protect the test tube from being broken. In addition, a gap is provided at the lower end of the rubber sheath, so that the test tube can be more easily inserted into the rubber sheath.

Detailed ways

Below in conjunction with accompanying drawing, specific embodiment of the present utility model is described in detail.

In the embodiment of the present utility model, as shown in Figures 1-3, a test tube fixing device for a vortex mixer is provided, including a bracket and a test tube cover. The support includes a base 1, on which a vertical rod 2 is arranged, and for the stability of the support, the vertical rod 2 is fixed on the base 1. The vertical bar 2 is provided with a cross bar 3, and the cross bar 3 is movably connected with the vertical bar 2. The cross clamp is generally used in the laboratory to realize the movable connection between the horizontal bar 3 and the vertical bar 2, but in this way, each time the position is adjusted, the cross clamp must be unscrewed first, and the operation is very troublesome. In the utility model, in addition to the above-mentioned method, the lifting sliding sleeve can also be used to connect the horizontal bar 3 and the vertical bar 2. The lifting sliding sleeve can adjust and rotate the position of the horizontal bar by pressing the button, and release it after adjusting to a suitable position. Just a button, easy to operate and labor-saving.

Test tube cover comprises slide block 6 and rubber sheath 5, and rubber sheath 5 is cylindrical, because rubber sheath 5 has elasticity, so the diameter of rubber sheath 5 is set smaller than the diameter of test tube, to reach better fixing effect. After the rubber sheath 5 is set on the test tube, in order to prevent the liquid in the test tube from splashing during the mixing process, the rubber sheath 5 top seals. Moreover, in order to facilitate the fitting of test tubes, a rectangular notch is provided at the lower end of the rubber sheath 5, which accounts for 1/4 to 1/3 of the length of the entire rubber sheath 5, and the length of the whole rubber sheath 5 is 1/4 to 1/3 of the length of the test tube. /3. In order to avoid damage to the test tube caused by the vibration of the vortex mixer, the rubber sleeve 5 is connected with the slider 6 through the elastic rod 7. Due to the existence of the elastic rod 7, the force exerted by the vortex mixer on the test tube directly acts on the elastic rod 7 and the actual force on the test tube The acting force is greatly reduced, thereby effectively protecting the test tube. The slide block 6 is movably installed on the cross bar 3, and the way of movable connection in the utility model is that an arc-shaped through groove 8 is arranged at the bottom of the slide block 6, and the radius of curvature of the arc-shaped through groove 8 is slightly smaller than that of the cross bar 3 The radius of, and, the section of arc-shaped through groove 8 is preferably a superior arc. The slider 6 is clamped on the cross bar 3 through the arc-shaped through slot 8 .

When in use, break open the opening at the lower end of the test tube cover 5, insert the test tube into the test tube cover 5, then clamp the slider on the cross bar 3, and adjust the cross bar 3 to a suitable height and angle by adjusting the lifting sliding sleeve 4, Then adjust the slide block 6 to make the test tube reach a suitable position. Turn on the vortex mixer switch to start the mixing process.

Although the specific implementation of the utility model has been described in detail in conjunction with the accompanying drawings, it should not be understood as limiting the scope of protection of this patent. Within the scope described in the claims, various modifications and deformations that can be made by those skilled in the art without creative work still belong to the protection scope of this patent.
