DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0016] Combined with Figures 1 to 3 shown in:
[0017] An adjustable test tube rack includes a bottom plate 1. Side plates 2 are vertically provided at both ends of the bottom plate 1. A rear plate 3 is vertically arranged on one side of the bottom plate 1. The two ends of the rear plate 3 are connected to the side surfaces of the side plates 2 at both ends of the bottom plate 1. It is characterized in that: Adjusting grooves 4 are respectively provided above the middle parts of the side plates 2 for adjusting the height of the mounting plate 5. A mounting plate 5 is arranged between the adjusting grooves 4. A plurality of mounting holes 6 are provided on the mounting plate 5 for placing test tubes. Support rods 7 are provided at both ends of the mounting plate 5. One end of the outer side of the support rod 7 is provided with a thread, and a wing nut is arranged on the thread. Through the cooperation of the wing nut, the thread and the side plate, the height of the support rod 7 is fixed. The support rod 7 is arranged in the adjusting groove 4. A mounting groove 8 is arranged inside the mounting plate 5. Sliding grooves 9 are respectively provided on both sides of the mounting groove 8. Oppositely arranged sliding rods 10 are arranged in the sliding grooves 9. The sliding rods 10 on both sides of the mounting groove 8 are connected by a support rod 11. The support rod 11 is vertically arranged on the support rods 7 at both ends of the mounting plate 5.
[0018] The sliding rod 10 is a convex sliding rod 10. The sliding rods 10 are arranged transversely and inwardly opposite to each other. An arc-shaped groove 12 corresponding to the mounting hole 6 is provided at the upper end of the convex structure of the sliding rod 10. Relative support is provided through the structure of the arc-shaped groove 12. Grooves are provided above and below the mounting plate 5 at the position between the arc-shaped grooves 12. A spring cylinder 13 is provided in the groove. A spring groove 14 is provided in the spring cylinder 13. A spring is provided in the spring groove 14. Sliders 15 are provided at both ends of the spring. A spring rod 16 arranged outward is provided on the slider 15. The spring rod 16 abuts against the sliding rod 10 to provide an outward elastic force of a certain magnitude, so that the position of the sliding rod 10 is convenient to fix.
[0019] Fixing blocks 17 are provided above and below the sliding rods 10 at both ends of the mounting plate 5 to prevent the sliding rods 10 from loosening outward. Threads are provided on the support rod 11, screw holes corresponding to the threads are provided on the sliding rod 10, and a wing nut is provided on the support rod 11 outside the sliding rod 10. Through the wing nut at this place, an inward force is applied to the sliding rod. It is fixed in cooperation with the spring, effectively increasing the stability of the structure of the present utility model. A circular groove 18 corresponding to the mounting hole 6 is provided on the bottom plate 1 for supporting the bottom of the test tube.
[0020] Working principle: According to the height of the test tube, the height of the mounting plate is controlled by adjusting the groove, the threads at both ends of the support rod and the wing nut to fix it on the side plate. When adjusting the aperture according to the test tube, the wing nut on the support rod and the thread cooperate to make the sliding rod move inward. At this time, the spring contracts, and the distance between the corresponding arc-shaped grooves shortens. Through the elastic force, the sliding rod maintains a certain tension, and at the same time, the clamping radius is reduced to adapt to a test tube with a smaller radius.
[0021] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
[0022] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
