Description

[Detailed description of the invention] (Industrial application field) This invention is a method for arranging test tubes containing samples for cold preservation of serum, blood, and other various tests, and for keeping the tube openings cool, stirring, and preventing various germs. This invention relates to a test tube stand case with a lid for medical and analytical purposes, which is closed with an opening/closing lid for purposes such as medical and analytical purposes.

(Prior art) A conventional test tube stand case with a lid that allows the internal state of a group of test tubes arranged upright to be seen from the outside is the product of Utility Model Publication No. 59-20348. The opening/closing lid mechanism that accommodates test tubes of different heights has vertical guide protrusions arranged side by side on both side plates of the case body, horizontal parallel teeth are carved between them, and the guide protrusions are provided on the sides of the cover plate. Parallel teeth that mesh with the parallel teeth on the case body side are carved on the inner surface of the leg piece that is vertically installed so as to be guided between the face leg pieces of the lid plate. Since the lid is opened and closed by engaging or disengaging the parallel teeth of the lid, this conventional product has many drawbacks as follows.

1. Since the height position of the closing lid leg changes depending on the height of the test tubes aligned with the case body, when the parallel teeth of the closing lid leg mesh with the parallel teeth on the case body side, the height of the closing lid leg changes. Depending on the height, the teeth may overlap the peaks and slide from the peaks to the valleys, resulting in a slip-off engagement.

In this case, the lid may be slightly misaligned in the slipping range, causing the lid to become loose and unreliably closed, and there is a risk that the lid may be opened accidentally.

2. The engagement of the closing lid with both parallel teeth is a lid closing that relies solely on the intuition of the operator, so depending on how the lid is held down, the engagement position of both leg pieces may be misaligned, resulting in a distorted closing state. Therefore, it is not always possible to close the lid evenly and tightly with both leg pieces at the same height each time the lid is closed.Furthermore, the meshing of the fine parallel teeth tends to cause tooth ridges to rub against each other and cause abrasion, which tends to cause the lid to loosen and close. .

3. Also, the lid plate is opened and closed by grasping the lower ends of both legs of the lid plate at the same time and forcefully opening the springs from below. The spring resistance is large, and the base part is easily broken, resulting in a lack of safety and long-term usability, resulting in many defective products.

4. Resin leg pieces are easy to break even when opening and closing the lid at room temperature, but since this product is often used in cold storage, the breakage rate is high in that cold state.

5. Opening the spring at the same time from under both legs is extremely troublesome because the lid cannot be opened and closed with one touch.

(Problems to be solved by the invention) The present invention eliminates all the drawbacks of the conventional products, makes the opening/closing lid of this product an easy-to-operate one-touch mechanism, and also enables the lid to be opened and closed at room temperature or in a cold state. It guarantees completely safe and reliable lid opening and closing without breakage of the legs, and it can immediately respond to any abnormal changes in the alignment of the test tubes, ensuring that the lids are always closed evenly regardless of how the lids are held down. To provide a product with a one-touch lid that can accurately close the lid without distortion, can be opened and closed with one touch very smoothly, has excellent long-term usability, is in extremely high demand, and allows one-touch lid to be checked to see the internal state of the test tube. The purpose is to

(Means for Solving the Problem) A single or multiple supporting plate shelf with holes for passing test tubes arranged at certain positions, a bottom of the same size as the shelf, and a horizontal position between the bottom and the shelf. A case body consisting of a pair of side plates fixed to the case body, and a lid plate covering the top surface of the case body. Opposing guide frames are arranged in series at intervals on the outer surfaces of both side plates of the case body. A pair of hook sliders, each having a stopper screw attached to the guide frame and having an upwardly tapered hook claw at the upper end, are fitted on both sides of the cover plate between the openings of the guide frame. The leg piece is guided and provided with a gap with respect to the side plate, and the leg piece is provided with a downwardly tapered hook claw whose lower end is hooked to the hook claw of the slider. The hook slider mechanism is provided with a scale for positioning the hook slider.

(Function) A pair of hook sliders fitted into opposing guide frames that are symmetrically arranged on the outer surface of both side panels of the case body will slide the guide frames up and down by loosening the attached stopper screws. However, the position is fixed by tightening the screw against the outer surface. Then, the legs of the lid that presses the slider position from above the case body are guided between the openings of the guide frame, and the hook claws of the legs hook into the hook claws of the slider. If the lid plate is fixed in advance at a height that securely closes the opening of the test tube, and the leg pieces are guided between the corresponding openings of the guide frame, the gap between the side plate and the leg pieces will be reduced. Due to the presence of the part, the hook claw of the leg piece easily hooks onto the hook claw of the corresponding slider due to the inner spring movement of the leg piece within the gap, and both leg pieces are locked at a predetermined exact position. , resulting in accurate lid closure without distortion.

Then, by one-touch operation of lightly pushing both the hooked legs inward with fingers, both the legs spring inwardly within the gap, and the hooks are smoothly released and the lid can be opened easily.

The position of the slider can be changed by adjusting the stopper screw to adjust the slide to an accurate position at the same height on both the left and right sides according to the height of the test tube. Note that if the stopper mechanism is provided with a scale, the slider can be positioned more simply, quickly and accurately by matching the scale.

(Example) The present invention is based on a test tube rack case with a lid that allows the internal state of a group of test tubes containing samples for serum cooling or other various tests to be seen from the outside. , the following is an explanation of the embodiment with reference to the drawings.

In FIGS. 1 to 4, the case body a has one or several tiers of supporting flat shelves 3 having the same external shape and having holes 2, 2' arranged in a fixed manner for arranging a group of test tubes in series.

11', a pair of hook sliders 12,
12' (see FIG. 5), respectively, into the rail grooves 7,
Corresponding slide pieces 11, 11' are fitted to 7' so that the frames 6, 6' can be vertically positioned and fixed by adjusting the screws 8, 8'.

The cover plate b, which covers the upper surface of the case body a, is made of the same material as the case body a, has a downward circumferential side 13, and is made of plastic sponge suitable for pressing and closing the tube opening of the test tube 1 on the back side. Alternatively, a rubber cushion plate 14 is fitted and guided between the openings of the respective guide frames 6, 6' of the case body a to the circumferential side 13 and between the side plates 5, 5'. Gap portion 15,
15' is provided, and the lower end is connected to the slider 12,
As shown in FIG. b towards the upper surface of case body a, and both leg pieces 17, 17' are attached to the corresponding guide frame 6,
6', and insert the hook claw 1 at the lower end.
6, 16' are covered by sliding the opposed tapered portions onto the hook claws 10, 10' on the slider 12, 12' side.

Note that the guide frames 6 and 6' are installed on the case body a.
A plurality of sliders 12, 12' and leg pieces 17, 17' of the cover plate b may be provided in a corresponding plurality depending on the size of the slider 12, 12'.

Another embodiment, as shown in FIG. Alternatively, for the slider mechanical part of the combination of the surfaces of the guide frames 6, 6' and the side surfaces of the hook sliders 12, 12', the sliders 12, 1

In addition, the scale 1 provided on the surface of the guide frames 6 and 6'
In the case of scale 8, it is aligned with the scale 20 on the lower side or side surface of the slider 12, 12'. In the case of scale 19 provided on the outer surface of the side plate 5, 5', it is aligned with the lower side of the slider 12, 12'.

With the above-mentioned configuration, the present invention allows the internal state of the test tubes arranged in the holes 2 and 2' of the supporting plate shelves 3 and 3' of the case body a to be seen from the outside, and from above the case body a to the cover plate b. A cushion plate 14 provided on the back side
The tube opening of the test tube 1 is closed by pressure to form a closed lid, and the leg pieces 17, 17' are guided between the openings of the corresponding guide frames 6, 6' to close the lid.

Then, depending on the height of the test tube 1, slide pieces 11 and 1 are inserted into the rail grooves 7 and 7' of the guide frames 6 and 6'.
1' is fitted into the hook slider 12, 12'
Loosen the stopper screws 8, 8' and remove both leg pieces 17,
Slide the guide frames 6, 6' toward 17',
the slider 12 with opposing hook claws 16, 16';
The sliders 12, 12' are positioned to be hooked to the hook claws 10, 10' of the sliders 12', and the screws 8, 8' are tightened to fix the sliders 12, 12' in position at the same height on the left and right sides.

Next, the mutual hook claws 10, 10', 16, 1
The 6' hook and its release are explained in Figure 4.
This is because the sliders 12, 12' have outwardly facing L-shaped parts 9, 9' that protrude outward from the guide frames 6, 6', and both leg pieces 17, 17' of the cover plate b and the side plate 5, 5' and the gap 15, 1
5', the leg pieces 17, 17' spring inwardly within the gaps 15, 15' as shown by dotted lines as the opposing tapers slide, thereby ensuring smooth and reliable movement.

To fix the hook sliders 12, 12' with screws,
If a pointed screw is used, it will form a prick on the side plates 5, 5' and will be reliable. Therefore, the slider 12,1
2' is fixed in the hook position in advance, the legs 17, 17' of the closing lid can be simply guided between the openings of the guide frames 6, 6', and the hook state will always be maintained at the same hook position. Made sure, without any distortion
Accurately closes the lid.

As a result, if the height of test tube 1 changes,
As long as the sliders 12, 12' are adjusted to the optimal hook position for both leg pieces 17, 17' whose positions have changed, the hooks can be closed evenly even when the height changes. The lid can be closed. There is no fear that the inner spring-moving leg pieces 17, 17' will break.

Next, when the closing lid is opened by lightly pressing both the leg pieces 17 and 17' with your fingers, both the leg pieces 17 and 17' will move between the gaps 15 and 1.
By moving the inner spring at 5', the hook can be smoothly removed with a single touch operation, and the lid can be opened by lifting the lid plate b. If the scales 18, 19, 20 of the other embodiments are provided on the slider mechanism, the sliders 12, 12' can be quickly and accurately positioned by adjusting the scales.

In this way, as long as the sliders 12, 12' are positioned and fixed in advance according to the abnormal height of the test tube 1, the cover plate b can be opened and closed evenly with one touch.

(Effects) As described above, the present invention has the following advantages: 1. Opening and closing of the lid of the case body a according to the abnormal height of the test tube 1 can be done reliably, accurately and safely with a very simple one-touch operation, and compared to the conventional product, Handling the lid is much easier and safer.

2 By positioning the hook sliders 12 and 12' in advance, the lid will not be distorted and the test tube will be able to respond immediately to any abnormal height of the test tube 1, ensuring that the lid is closed evenly regardless of how the lid is held down. The lid can be closed,
Opening the lid can be done smoothly with one touch by simply pushing the legs 17, 17' inward with your fingers, which is very convenient.

3. The hook in the designated position is completely smooth, reliable, and has no rattling, and the claws are less likely to wear out, ensuring a strong closing with a light clicking sound.

4 Unlike opening and closing the lid by springing the leg pieces 17, 17' inward, unlike opening outward, there is less spring resistance at the base, so the leg pieces 17, 17' can be opened and closed at room temperature.
There is no need to worry about it breaking even when kept cold, it is completely safe and can be used for a long time, and its product value is extremely high, along with the one-touch lid, and it is in high demand.

5. Positioning of the sliders 12, 12' requires simple screw adjustment, and if the slider mechanism is provided with scales, the positioning can be made easier and more accurate, which is very convenient.

This has an excellent effect.
