Description

[Detailed description of the invention] This invention relates to a structure for mounting a support bar to prevent reagent bottles placed on the medicine side from falling in the event of a disaster such as an earthquake.

As a conventional support bar mounting structure, for example, the structure shown in FIG. 1 is generally known.

That is, 101 in the figure indicates the drug side, and the drug side 101
are both side walls 103 (one not shown) and both side walls 1
It is composed of a support shelf 105 whose both ends are fixedly supported by the support shelf 105, and longitudinal support bars 107, 107 arranged on the front side and the rear side of the support shelf 105.

Both ends of the support bar 107 are supported by fixtures 111 screwed 109 to the side walls 103.

Since the conventional support bar 107 is fixed at a predetermined height using a fixture 111, for example, the mounting position of the support bar can be set to the optimum position for the reagent bottle depending on the height of the bottle. There was a problem in that there were cases where the support bar did not function as a support bar.

Therefore, the object of this invention is to provide a new means that allows the mounting position of the support bar to be easily changed without using tools or the like, and that can be securely fixed using screw holes.

In order to achieve the above object, this invention has a plurality of pairs of fitting recesses provided on both side walls on the medicine side and a shaft hole formed as a blind hole in the axial direction, and the fitting A fitting protrusion is removably fitted to the recess, and both ends are fitted in the axial direction of the fitting protrusion, and the play with the shaft hole is set to be larger than the fitting clearance of the fitting protrusion. It consists of a support bar of different length.

Hereinafter, one embodiment of this invention will be described in detail with reference to the drawings of FIGS. 2 to 5.

In Figure 2, 1 is the medicine side 1, and both side plates 3 that also serve as supporting legs
3 and two upper and lower support shelves 5, 5 whose ends are supported by side plates 3, 3.

A plurality of pairs of fitting recesses 9 are provided in both side walls 7, 7 of the drug side 1 in the front-rear direction.

In this embodiment, three fitting recesses 9 are formed in the screw hole 11 in the vertical direction.

A fitting protrusion 13 is fitted into the fitting recess 9 .

The fitting convex portion 13 is composed of a fitting main body portion 19 having a threaded portion 15 that can be screwed into the screw hole 11 of the fitting recess 9 and a shaft hole 17 formed as a blind hole in the axial direction. There is.

Both ends of the support bar 21 are fitted into the shaft hole 17 of the fitting convex portion 13 .

The length of the support bar 21 is such that the fitting convex portion 13 is connected to the fitting concave portion 9.
When the fitting protrusion 1 is inserted into the screw hole 11 of
The play H of the end of the support bar 21 in the shaft hole 17 of No. 3 is set to be larger than the fitting allowance 1, which is the threaded portion 15 of the fitting portion 13.

Therefore, according to this embodiment, in order to adjust the height of the support bar 21 in accordance with the height of the reagent bottle, one of the fitting convex portions 13 is fitted into the fitting recess 9, and then the fitting convex portion 13 is fitted into the fitting concave portion 9, and then Part protrusion 13
Fully insert one end of the support bar 21 into the shaft hole 17 of the.

Next, the other fitting recess 9 is fully fitted into the other end of the support bar 21 as shown in FIG.

At this time, the dimension W of the support bar 21 is the distance α between the side walls 7, 7.
Since it is slightly shorter, the threaded portion 15 of the fitting convex portion 13 is made to correspond to the threaded hole 11 along the side wall 7 from the front side.

Attachment is completed by screwing together the threaded portion 15 in this state.

In this attached state, both ends of the support bar 21 are within the play allowance of the shaft hole 17, so that both ends are securely supported without coming off.

As explained above, according to this invention, the mounting position of the support bar can be easily changed without using any tools.

This enables optimal positioning with respect to the reagent bottle, and the support bar can be securely fixed by the screw-fastened mating protrusions on both ends, and is effective as an anti-overturn function depending on the height and size of the reagent bottle. started working.
