[0004] Therefore, it is particularly important to design and manufacture a sample storage tube that can realize convenient anti-deflection limiting treatment after screwing the screw cap and improve the operation convenience and structural stability of the sample storage tube in the actual use of environmental monitoring. UTILITY MODEL CONTENT

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Please refer to Figures 1-3 The utility model provides a technical scheme: an environment monitoring sample storage tube, which comprises a transparent tube body 1 and a screw cap 2 installed on the upper end of the transparent tube body 1 through screwing, and a deviation prevention mechanism for limiting the axial rotation of the screw cap 2 to prevent the screw cap 2 from being opened by mistake is arranged between the upper end of the transparent tube body 1 and the lower end of the screw cap 2.

[0027] Specifically, as shown in Figure 1 and Figure 2 The deviation prevention mechanism comprises a slip ring 3 movably sleeved on the upper end of the transparent tube body 1 and located below the screw cap 2, limit blocks 301 symmetrically fixed on the upper end of the slip ring 3 and penetrating upward through the screw cap 2, and a plurality of limit slots 201 annularly arranged on the outer side of the lower end of the screw cap 2 and used for accommodating the upper ends of the limit blocks 301. When the limit blocks 301 on the slip ring 3 are inserted upward into the limit slots 201 of the screw cap 2, the axial rotation of the screw cap 2 on the transparent tube body 1 can be limited, so that the anti-deviation locking operation of the screw cap 2 is performed.

[0028] Specifically, as shown in Figure 1 and Figure 2As shown, the upper end of the transparent tube body 1 is fixedly connected with an upper limiting ring 103 abutting against the lower end of the screw cap 2 between the screw cap 2 and the sliding ring 3. The left and right ends of the upper limiting ring 103 are provided with guide grooves 104 for accommodating limiting blocks 301. Meanwhile, the upper end of the transparent tube body 1 is fixedly connected with a lower limiting ring 102 below the sliding ring 3. The upper limiting ring 103 and the lower limiting ring 102 can limit the sliding range of the sliding ring 3 in the transparent tube body 1, so that the limiting blocks 301 can be stably arranged in the guide grooves 104 of the upper limiting ring 103, and the limiting blocks 301 are prevented from deviating.

[0029] Specifically, as shown in Figure 1 and Figure 2 The front end of the transparent tube body 1 is provided with a scale bar 101. The outside of the transparent tube body 1 is sleeved with a light-shielding and heat-insulating sheath 4 below the lower limiting ring 102. The front end of the light-shielding and heat-insulating sheath 4 is provided with a vertical insertion groove 401 for accommodating the scale bar 101. The vertical insertion groove 401 can prevent the light-shielding and heat-insulating sheath 4 from shielding the scale bar 101, so that the operator can normally watch the scale bar 101.

[0030] The light-shielding and heat-insulating sheath 4 and the vertical insertion groove 401 are symmetrically fixedly connected with two anti-back-off elastic sheets 402 elastically abutting against the upper end of the scale bar 101. When the light-shielding and heat-insulating sheath 4 is completely sleeved on the outside of the transparent tube body 1, the anti-back-off elastic sheets 402 can pass through the side wall of the scale bar 101, then elastically move to the upper end of the scale bar 101, and abut against the upper end of the scale bar 101, so that the locking force between the light-shielding and heat-insulating sheath 4 and the transparent tube body 1 is improved.

[0031] The light-shielding and heat-insulating sheath 4 is made of black polyurethane foam material. After being sleeved on the outside of the transparent tube body 1, the light-shielding and heat-insulating sheath 4 can shield light in the transparent tube body 1. The polyurethane foam has good heat-insulating performance, so that the sample in the transparent tube body 1 can be heat-insulated.

[0032] Working principle: in use, the slide ring 3 will be in contact with the lower limit ring 102 in the unused state, at this time the upper end of the limiting plug block 301 on the slide ring 3 can be hidden in the guide groove 104 of the upper limit ring 103, at this time the screw cap 2 can be normally opened and closed on the transparent tube body 1, when the sample is added to the transparent tube body 1, the screw cap 2 can be screwed on the transparent tube body 1, after the screw cap 2 is screwed tightly, the sample storage worker can hold and slide the slide ring 3 upwards, adjust the slide ring 3 upwards to abut against the upper limit ring 103, at this time the limiting plug block 301 on the slide ring 3 can be inserted into the limiting plug slot 201 on the screw cap 2 at the specified position, which can prevent the screw cap 2 from rotating axially on the transparent tube body 1; when the sample in the transparent tube body 1 needs to be shaded or heat preserved, the vertical insertion slot 401 on the shading and heat preservation sleeve 4 can be directed towards the scale bar 101 on the transparent tube body 1, the shading and heat preservation sleeve 4 can be vertically upwardly sleeved on the outside of the transparent tube body 1, and the sample can be shaded or heat preserved, so as to meet the actual sample storage use requirements of different samples.

[0033] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
