[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.
[0017] In the description of the present application, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0018] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0019] The following is combined with Figure 1-3 This application is described in further detail.
[0020] The embodiment of the present application discloses a test tube rack for laboratory use, including a base 1, a bracket 2 and a group of limiting mechanisms 3. It should be noted that a group of corresponding test tube holes 4 are provided on the base 1 and the bracket 2 for storing test tubes. In order to better protect the test tubes, elastic protective rings are bonded to the inner sides of the test tube holes 4. It should be further noted that each group of test tube holes 4 is arranged in sequence from large to small, so that test tubes of different sizes can be conveniently stored. In order to improve the storage effect of the test tubes, a horizontal plate 8 is fixedly connected between the inner walls on both sides of the base 1, and a group of test tube holes 4 are also correspondingly provided on the horizontal plate 8.
[0021] See also Figure 1 and Figure 3 The limit mechanism 3 includes a chassis 31, the bottom of the chassis 31 is fixed to the base 1, and the top of the chassis 31 is fixedly connected with a screw rod 33, and a round rod 32 is threadedly sleeved on the screw rod 33, and the height of the round rod 32 can be adjusted by rotating the round rod 32. It should be noted that a ring 34 is sleeved on the lower end of the round rod 32, and the round rod 32 is rotatably connected to the ring 34. When the round rod 32 moves vertically, the ring 34 follows the round rod 32 to move vertically. It should be further noted that a group of elastic abutment strips 35 are connected between the ring 34 and the chassis 31. As the ring 34 moves vertically, the distance between the ring 34 and the chassis 31 changes, and the expansion range of the abutment strip 35 also changes. In this way, the abutment force of the abutment strip 35 can be adjusted, so as to better limit the inverted test tube, prevent the test tube from shaking, and improve the protection of the test tube.
[0022] See also Figure 1 and Figure 2In order to improve the storage effect of the test tube rack for test tubes, a lifting mechanism is arranged between the base 1 and the bracket 2. It should be noted that the lifting mechanism includes a telescopic plate 5, the top of the telescopic plate 5 is fixed to the bottom of the bracket 2, and a group of positioning holes 6 are opened on the side of the telescopic plate 5 close to the limiting mechanism 3, and the positioning holes 6 are equidistantly distributed. It should be further noted that the base 1 is threadedly connected with a knob 7 at the position corresponding to the positioning hole 6. By tightening the knob 7, the tip of the knob can be inserted into the positioning hole 6 to fix the bracket 2. It can be understood that in order to facilitate the storage of the telescopic plate 5, a storage groove for accommodating the telescopic plate 5 is opened on the base 1, and the telescopic plate 5 is slidably connected to the storage groove. In order to improve the stability of the base 1, a layer of rubber pad 9 is arranged at the bottom of the base 1, and the bottom of the rubber pad 9 is provided with anti-slip grooves.
[0023] The implementation principle of a laboratory test tube rack in the embodiment of the present application is as follows: when it is necessary to invert an unused test tube, first, according to the different sizes of the test tube, the height of the ring 34 can be adjusted by rotating the round rod 32, so as to adjust the distance between the ring 34 and the base 31, thereby adjusting the expansion range of the abutment bar 35, and thus better limiting the inverted test tube, preventing the test tube from shaking, and improving the protection of the test tube; when it is necessary to adjust the height of the bracket 2, first, the telescopic plate 5 can be released by loosening the knob 7, and then the bracket 2 and the telescopic plate 5 can be pulled up as a whole, and finally fixed by tightening the knob 7.
[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
