Description

[Detailed Description of the Invention] The present invention relates to an improvement of a metal test tube stand.

Conventionally, various structures have been devised for this type of test tube rack, but because such test tube racks cannot be stacked vertically, they are not suitable for laboratories that require a large number of test tubes. The disadvantage of this method was that it required a large planar space for storing test tubes.

Therefore, the present invention aims to provide a test tube rack that can be stacked vertically and that can sufficiently accommodate a large number of test tubes even in a narrow space.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 is a front view of a test tube rack according to the present invention, and FIGS. 2 and 3 are a left side view and a plan view thereof, in which 1 is a rectangular frame-shaped left support leg;
1 is a right support leg in the form of a rectangular frame, and an upper grid body 3 for a test tube section is horizontally stretched between the upper parts of the left and right support legs 1 and 2.

This upper lattice body 3 is constructed by combining a plurality of horizontal rods 4 extending in the left-right direction and a plurality of vertical rods 5 extending in the front-rear direction in a lattice shape, and forming a rectangular upper part for erecting test tubes between each rod 4 and 5. Spaces 6, 6... are formed.

Further, a lower lattice body 7 for a test tube section is stretched horizontally between the center portions of the left and right support legs 1 and 2.

Similar to the upper lattice body 3 described above, this lower lattice body 7 also has a plurality of horizontal lattice blocks 8 extending in the left-right direction and a plurality of vertical lattice blocks 9 extending in the front-rear direction, which are combined in a lattice shape, so that each bar 8, A large number of rectangular lower spaces for erecting test tubes are formed between the test tubes, and the lower spaces and the upper spaces are arranged to face each other in the vertical direction.

Furthermore, a bottom frame 10 for supporting the bottom of the test tube is stretched horizontally between the lower portions of the left and right support legs 1 and 2.

This bottom plate 10 includes a left bottom step 11 horizontally welded to the lower part of the left support leg 1, a right bottom step 12 horizontally welded to the bottom of the right support leg 2, and a space for installing the test tubes. Left and right soles 1 facing the center of
A pair of parallel wire rods 13 stretched between 1 and 12...
The upper lattice body 3, the lower lattice body 7, and the bottom frame 10 are joined at their central portions in the left-right direction by a rectangular reinforcing frame 14.

Furthermore, reinforcing members 15 and 16 are horizontally welded and fixed to the support legs 1 and 2 at the upper and lower portions of the lower grid body 7 in the front and rear directions.

In the test tube stand constructed as described above, a total of four coupling and locking bodies 17 are welded and fixed to the upper corner portions of each of the left and right support legs 1 and 2, as clearly shown in FIG. 4.

This binding and locking body 17 has a special shape in which a U-shaped binding part 17b is integrally formed on the upper end of an inverted L-shaped part 17a, and two parts of the inverted L-shaped part 17a are connected to the upper corners of the support legs 1 and 2. It is fixed by welding to the part.

In addition, the binding and locking body 17 secures the lower end of the support leg of the upper test tube stand B (see the imaginary line in the figure) which is stacked on the test tube stand A shown in solid lines in FIGS. 1 and 2. , the U-shaped coupling portion 17b...
It is designed so that it can be removably fitted.

With this configuration, the upper test tube stand B can be stacked on top of the lower test tube stand A, and another test tube stand can be stacked on top of that in sequence.
It has the effect of being able to sufficiently store a large number of test tubes even in a narrow space.

FIG. 5 is a perspective view showing another embodiment, in which a removable coupling stopper 18 that can be attached to and detached from the left and right support legs 1 and 2, in place of the fixed coupling stopper 17 of the previous embodiment.
It is attached.

That is, the coupling and locking body 18 has U-shaped attachment/detachment parts 20, 20 formed by integrally bending them at both lower ends of the gate-shaped part 19, and a C-shaped coupling part 20 at the upper horizontal part 19a of the gate-shaped part 19. The locking part 21 is fixed by welding, and the detachable parts 20, 20 are removably attached to the left and right support legs 1, 2 (however, in FIG. 5, only the left support leg is shown for convenience of illustration). When the test tube racks are stacked vertically, the binding locking body 18 is used, and when stacking is not necessary, the binding locking body 18 is removed from the test tube rack. When using the test tube stand alone, the binding locking body 18 can be removed, so the binding locking body 18 does not get in the way, and the binding locking body 18 can be used as an attachment in an existing test tube stand. It also has the effect of being able to be attached to. Moreover, in the case of this embodiment, the height can be adjusted according to the height of the test tube. Hereinafter, the embodiment shown in FIG. 5 also has the same effect and function as the previous embodiment.
Therefore, in FIG. 5, the same parts as in FIGS. 1 to 4 are given the same numbers, and detailed explanation thereof will be omitted.

FIG. 6 is a perspective view showing still another embodiment, in which the binding and locking body 22 is configured to be adjustable up and down, maintaining an appropriate vertical space according to the height of the test tube, and eliminating wasted space, so-called play. It is designed to eliminate this problem.

That is, the binding and locking body 22 has two iron wires 23, 2.
The lower end of the hook-shaped bent portions 23a, 23a are engaged with the bottom rod 11 so that the two iron wires 23, 23 can be raised using the bent portions 23a, 23a as fulcrums. The upper ends of the two iron wires 23, 23 are bent round to form sliding guide rings 24, 24, while the vertical parts 25a, 25a of the portal rod 25 are guided downward through the sliding guide rings 24, 24. At the lower ends of the vertical parts 25a, 25a of the portal frame 25, the upper horizontal parts of the support legs 1 or the reinforcing rods 1 are attached.
Engagement claws 26, 26 that can selectively engage with 5, 16
A C-shaped coupling and locking part 27 is welded and fixed to the upper horizontal part 25b of the portal rod 25.

With this configuration, the vertical position of the C-shaped conjugation locking part 27 can be selectively set according to the height of the test tubes, so when the test tube stands are stacked vertically, the upper and lower test This has the effect of eliminating wasted space between pipe stands.

Hereinafter, the embodiment shown in FIG. 6 will have the same effect and effect as the embodiment described earlier with reference to FIGS. 1 to 4.
Therefore, in FIG. 6, the same parts as in FIGS. 1 to 4 are given the same numbers, and detailed explanation thereof will be omitted.

As described in detail above, the present invention consists of a test tube in which an upper lattice body 3 and a lower lattice body 7 for a test tube section are stretched horizontally between the left and right supporting legs 1 and 2 in the shape of a rectangular frame. A coupling and locking body 17 that removably engages the ends of the support legs 1 and 2 of the stacked test tube stands when the test tube stands are stacked.
Since the coupling and locking body 17 is attached to each of the left and right support legs 1 and 2, test tube stands can be stacked up and down, and as a result, a large number of test tubes can be tested even in a narrow space. This has the effect of allowing the tube to be sufficiently stored.
