[0002] Sampling is required before rapid testing of aquatic products. In order to shorten the sampling time of aquatic product samples, it is generally necessary to first conduct centralized sampling of different aquatic products on site, then seal the aquatic product samples (muscle, viscera, etc.) in self-sealing sample bags, and finally temporarily store the sample bags containing aquatic products in plastic baskets or storage boxes awaiting testing.
[0003] The sample bags containing aquatic products are temporarily stored in plastic baskets or storage boxes. The sample bags are stacked together in a disorderly manner, making it inconvenient to take and put. In addition, the sample bags are exposed to the external environment, making the samples extremely susceptible to factors such as light and temperature in the external environment, causing the photosensitive and heat-sensitive substances therein to decompose, affecting the test results. Summary of the invention
[0004] The present invention aims to solve the above-mentioned problems existing in the prior art of temporarily storing sample bags in plastic baskets or storage boxes, and provides a storage device for on-site rapid testing of water product samples, which has an ingenious structure, can isolate the sample bags from the external environment, and can realize independent placement and retrieval of sample bags, and is very quick and convenient.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an on-site rapid testing water product sample storage device of the present invention comprises a box body with an open front side, a plurality of partitions are arranged at intervals in the box body, the partitions divide the internal space of the box body into a plurality of independent storage chambers, the storage chambers are provided with a sample bag storage box with an open top, an elastic pushing and retracting mechanism is provided at the rear of the sample bag storage box for pushing the sample bag storage box out of the storage chamber, and an elastic limiting mechanism is provided on the upper side wall of the storage chamber at the opening for limiting the sample bag storage box from being pushed out of the storage chamber by the elastic pushing and retracting mechanism. The internal space of the box body in the present invention is divided into a plurality of independent storage chambers by partitions. The storage chambers are used to place sample bag storage boxes. The sample bag storage boxes can be pushed into the storage chambers or pulled out from the storage chambers (push-pull type), so that the sample storage boxes can be hidden in the storage chambers, which not only enables the sample bags to be taken and placed independently, placed in an orderly manner, and convenient to take and place, but also enables the sample bags to be located in the box body and isolated from the external environment, effectively avoiding the influence of factors such as light and temperature; the elastic pushing and shrinking mechanism is used to push the sample bag storage box out of the storage chamber, specifically, to expose part of the sample bag storage box to the outside of the storage chamber, so as to facilitate pulling the sample bag storage box out of the storage chamber, which helps to improve the convenience of taking and placing the sample bags; when the sample bag storage box is pushed into the storage chamber, the elastic limiting mechanism can block and interfere with the upper part of the front side of the sample bag storage box, thereby limiting the sample bag storage box from withdrawing / sliding out of the storage chamber.
[0006] Preferably, the elastic pushing and retracting mechanism includes a fixed U-shaped groove, a sliding U-shaped groove and a first spring, the fixed U-shaped groove is located in the accommodating chamber and fixedly connected to the rear side wall of the accommodating chamber, the notch of the fixed U-shaped groove faces the opening direction of the accommodating chamber, the sliding U-shaped groove is located in the accommodating chamber and slidingly cooperates with the accommodating chamber, the notch of the sliding U-shaped groove faces the fixed U-shaped groove, and the side walls on the same side of the fixed U-shaped groove and the sliding U-shaped groove are respectively provided with X-shaped telescopic brackets, and the two ends of the X-shaped telescopic bracket are respectively slidably connected to the side walls of the fixed U-shaped groove and the sliding U-shaped groove, the first spring is arranged between the fixed U-shaped groove and the sliding U-shaped groove, and the two ends of the first spring are respectively fixedly connected to the fixed U-shaped groove and the sliding U-shaped groove. The sliding U-shaped groove can slide along the containing chamber to push out the sample bag storage box or compress the first spring. The contact area between the sliding U-shaped groove and the sample bag storage box is large, and the sample bag storage box is relatively stable when it is pushed out or the first spring is compressed. The X-shaped telescopic bracket has a simple structure, and X-shaped telescopic brackets are respectively provided on the side walls on the same side of the fixed U-shaped groove and the sliding U-shaped groove (that is, it contains a pair of X-shaped telescopic brackets), and the sliding U-shaped groove slides more stably.
[0007] Preferably, the X-shaped telescopic bracket is composed of two connecting rods hinged by a pin in the middle, the side walls of the fixed U-shaped groove and the sliding U-shaped groove are provided with a sliding groove, and rolling pins are provided at both ends of the connecting rod, and the rolling pins are slidably matched with the sliding groove. Through the sliding match between the rolling pin and the sliding groove, the X-shaped telescopic bracket is flexible and not easy to get stuck, so that the sliding U-shaped groove slides smoothly and freely.
[0008] Preferably, limit sliders are provided at both ends of the sliding U-shaped groove, and travel limit grooves are provided on the upper side wall and the lower side wall of the accommodation chamber, and the limit sliders are slidably matched with the travel limit grooves. The limit sliders cooperate with the travel limit grooves to limit the pushing distance and speed of the sample bag storage box, so as to prevent the sample bag storage box from being quickly pushed out of the accommodation chamber.
[0009] Preferably, the elastic limiting mechanism includes a limiting column and a locking mechanism, a stepped sliding hole is provided on the upper side wall of the accommodating chamber at the opening, the limiting column is located in the large diameter hole in the stepped sliding hole, a reset push rod is provided on the limiting column, the reset push rod passes through the small diameter hole in the stepped sliding hole, and the part of the reset push rod located in the large diameter hole in the stepped sliding hole is sleeved with a second spring, the upper end of the second spring is fixedly connected to the stepped surface of the stepped sliding hole, and the second spring is fixedly connected to the limiting column, and the locking mechanism is arranged on the outer side of the stepped sliding hole for locking or releasing the limiting column, when the locking mechanism locks the limiting column, the lower end of the limiting column is exposed outside the large diameter hole in the stepped sliding hole and blocks and interferes with the sample bag storage box, and when the locking mechanism releases the limiting column, the lower end of the limiting column retracts into the large diameter hole in the stepped sliding hole. In the present invention, the sample bag storage box in the receiving chamber is limited by the blocking of the limiting column to limit the sample bag storage box from withdrawing / sliding out of the receiving chamber, and the structure is ingenious; when the locking mechanism locks the limiting column, the lower end of the limiting column is exposed outside the large-diameter hole in the stepped slide hole and blocks and interferes with the sample bag storage box. At this time, the sample bag storage box in the receiving chamber is blocked and interfered by the limiting column and cannot withdraw / slide out of the receiving chamber; and when the locking mechanism releases the limiting column, the limiting column moves upward under the action of the restoring force of the second spring and retracts into the large-diameter hole in the stepped slide hole. The sample bag storage box in the receiving chamber loses the limiting effect of the limiting column and can be pulled out of the receiving chamber.
[0010] Preferably, the locking mechanism comprises a pressing rod and an annular groove arranged on the outer circumferential surface of the limiting column, a transverse sliding groove is arranged on the outer side of the large diameter hole in the stepped sliding hole, a transverse sliding block and a third spring are arranged in the transverse sliding groove, an avoidance groove is arranged on the transverse sliding block, two ends of the third spring are against the transverse sliding block and the groove bottom of the transverse sliding groove, and a clamping head that matches the annular groove is arranged on the side of the transverse sliding block close to the limiting column, and when the clamping head is clamped into the annular groove, the lower end of the limiting column is exposed outside the large diameter hole in the stepped sliding hole and blocks the sample bag storage box. To prevent interference, when the clamping head withdraws from the annular clamping groove, the lower end of the limit column is retracted into the large diameter hole in the stepped sliding hole, and a sliding hole is provided on the upper side wall of the accommodating chamber, and the pressing rod passes through the sliding hole and slides with the sliding hole, and a lower pressure plate is provided at the upper end of the pressing rod, and the part of the pressing rod located between the lower pressure plate and the box body is sleeved with a fourth spring, and the lower end of the pressing rod extends into the avoidance groove, and an outward push portion is provided on the outer circumferential surface of the lower end of the pressing rod, and an outward push inclined surface is provided at the bottom of the outward push portion, and a guide inclined surface matched with the outward push inclined surface is provided on the upper part of the side wall of the avoidance groove away from the limit column. When the clamp head is stuck in the annular groove (the limit column is in a locked state at this time), the outward push inclined surface is opposite to the guide inclined surface. When the lower pressure plate is pressed downward, the outward push inclined surface squeezes the guide inclined surface outward, and the lower end of the pressing rod extends downward into the avoidance groove. At the same time, the outward push part pushes the transverse sliding block outward, the third spring is compressed, the transverse sliding block slides outward, and the clamp head gradually withdraws from the annular groove. After the clamp head is completely withdrawn from the annular groove (the limit column is in a loose state at this time), the limit column retracts into the large diameter hole in the stepped slide hole under the action of the restoring force of the second spring, and the clamp head is blocked by the limit column and cannot be stuck in the annular groove; to re-lock the limit column, just press the reset push rod downward to make the limit column move downward until the annular groove moves to the clamp head, and the clamp head is re-stuck in the annular groove, and the limit column is stuck by the clamp head and cannot move.

The longitudinal limit block cooperates with the longitudinal limit slot to prevent the push-out portion from colliding with the box body and being damaged, and at the same time prevents the pressing rod from rotating in the radial direction, ensuring that the push-out inclined surface is always precisely aligned with the guide inclined surface.
[0012] Preferably, when the clamp head is inserted into the annular groove, the upper end surface of the reset push rod is flush with the top surface of the box. With this structural design, as long as the upper end surface of the reset push rod is pressed to be flush with the top surface of the box, the clamp head is inserted into the annular groove to play a positioning role.
[0013] Preferably, a handle is provided on the front side of the sample bag storage box.
[0014] Preferably, connecting rings are provided on both sides of the box body, and a carrying strap is provided on the top of the box body, and both ends of the carrying strap are respectively connected to the connecting rings.
[0015] Therefore, the present invention has the following beneficial effects:
[0016] (1) The internal space of the box is divided into multiple independent storage chambers by partitions. The storage chambers are used to place sample bag storage boxes. The sample bag storage boxes can be pushed into the storage chambers or pulled out from the storage chambers (push-pull type), so that the sample storage boxes can be hidden in the storage chambers. This not only allows the sample bags to be taken and placed independently, in an orderly manner, and conveniently taken and placed, but also allows the sample bags to be located in the box and isolated from the external environment, effectively avoiding the influence of factors such as light and temperature;
[0017] (2) The elastic limiting mechanism can limit the sample bag storage box from withdrawing / sliding out of the receiving chamber;
[0018] (3) The elastic push-and-retract mechanism is used to push the sample bag storage box out of the storage chamber, so that part of the sample bag storage box is exposed outside the storage chamber, so that the sample bag storage box can be pulled out of the storage chamber, which helps to improve the convenience of taking and placing the sample bag.
