Description

Technical Field

[0001] This invention relates to a temporary holding device, and more particularly to a laboratory-grade high-density temporary holding device for snails. Background Technology

[0002] Snails (such as the wrasse) are commonly used to analyze toxins, heavy metals, and other chemical components, and are a common biological sample in aquaculture laboratories. After collection, snails are usually temporarily held in containers such as basins, turnover boxes, or buckets in the laboratory for subsequent experiments or tests. However, temporarily holding snails in such containers results in them piling up together, making them difficult to sort and handle, and also reduces the space utilization of the containers.

[0003] In addition, Chinese Patent No. CN208113799U, authorized on November 20, 2018, discloses a detachable aquatic holding box, which includes a holding box body composed of several square boxes with open tops. Each side of the square box is provided with two connecting holes. Multiple water pipes are provided on the top of the holding box body, and several water outlets corresponding to the positions of the square boxes are provided on the water pipes. The water pipes are set on the holding box body through several brackets. The holding box body is provided with connecting rods that connect the square boxes in series. The connecting rods pass through the square boxes through the connecting holes. Nuts are provided at both ends of the connecting rods. Openable and closable drainage holes are provided at the bottom of the square boxes. This holding box has the following defects: (1) It is large in size and occupies a large area when in use, making it unsuitable for use in the laboratory; (2) It has low space utilization. Summary of the Invention

[0004] The present invention addresses the aforementioned problems of existing aquatic holding tanks by providing a laboratory-grade high-density holding device for snails that is compact in structure, occupies little space, has high space utilization, and facilitates snail classification and handling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A laboratory high-density temporary rearing device for snails includes a box with an open top and a lateral telescopic mechanism. Several supports are spaced apart inside the box. Multiple pull-out breeding mesh baskets are spaced apart from top to bottom within each support. Several opposing guide grooves are provided on the inner wall of the box. Guide rails adapted to the guide grooves are fixed to the outer side of the supports. Several locking holes are spaced apart longitudinally on the guide rails. Locking pins that can be inserted into the locking holes are provided on the outer side of the box. The lateral telescopic structure is located on both sides of the box. The lateral telescopic structure can drive the locking pins to insert into or retract from the locking holes. When the locking pins are inserted into the locking holes, the positions of the supports and the box are relatively fixed. When the locking pins are retracted from the locking holes, the supports slide relative to the box. This invention is mainly used for the temporary holding of snails in the laboratory for testing experiments. The length, width, and height should not be too large to facilitate placement and use; the length should preferably not exceed 160cm, the width 60cm, and the height 60cm. This invention features multiple supports, each containing multiple layers of aquaculture mesh baskets. This design improves space utilization and facilitates the categorization and placement of snails. The water level during use is set according to actual needs. To remove snails, the lateral telescopic structure moves the locking pin out of the locking hole, unlocking the support. The aquaculture mesh baskets used for temporarily holding snails are then lifted to the desired height. The lateral telescopic structure then moves the locking pin into the locking hole, locking the support. The aquaculture mesh baskets can then be removed to retrieve the snails. After removal, the baskets are pushed back in to reset them. The lateral telescopic structure again moves the locking pin out of the locking hole to unlock the support, allowing the support and aquaculture mesh baskets to fall back into the housing. The guide rail serves both guiding and limiting functions, and also cooperates with the locking pin.

[0006] Preferably, the lateral telescopic mechanism includes a U-shaped frame, a movable plate, and a conical head disposed on one side of the housing. The movable plate is located on the outer side of the housing on both sides of the U-shaped frame, and the conical head is located inside the U-shaped frame. Ball heads are provided on both sides of the conical head. A connecting rod is fixed on the ball head, passing through the U-shaped frame and slidingly engaging with it. The outer end of the connecting rod is fixedly connected to the movable plate. A locking pin is fixed on the movable plate. A retaining spring is sleeved on the part of the connecting rod between the U-shaped frame and the ball head. The ball head contacts the inclined surface of the conical head under the action of the retaining spring. A pull rod is fixed on the conical head. The pull rod passes through the U-shaped frame and slidesly engaging with it. A handle is fixed on the outer end of the pull rod. A spring is sleeved on the part of the pull rod between the U-shaped frame and the handle. The lateral telescopic mechanism in this invention has a simple structure and is easy to use. When the pull rod is pulled outward, the spring is compressed, and the inclined surface of the conical head squeezes the ball head, thereby causing the connecting rod to drive the locking pins located on both sides of the box to move outward and exit the locking hole at the same time. When the pull rod is released, the spring returns to its original position, and the ball head slides along the inclined surface of the conical head, causing the connecting rod to drive the locking pins located on both sides of the box to move inward and insert into the locking hole at the same time.

[0007] Preferably, guide rods are fixed on both sides of the housing, the guide rods pass through the movable plate, and limit baffles are fixed to the outer ends of the guide rods.

[0008] Preferably, a fixed plate is fixed on the movable plate, and the locking pin is disposed on the fixed plate.

[0009] Preferably, the side plate of the U-shaped frame is provided with a guide sleeve, and the connecting rod passes through the guide sleeve and slides with the guide sleeve.

[0010] Preferably, the end face of the locking pin is spherical. The spherical surface serves as a guide.

[0011] Preferably, the support includes two opposing side panels and a partition spaced between the side panels, the space between adjacent partitions forming a placement chamber for placing the aquaculture mesh basket, and the guide rail is fixed to the outer surface of the side panels.

[0012] Preferably, the partition plate is provided with flow holes.

[0013] Preferably, the breeding grid basket is provided with limiting sliders on both sides, and the inner side of the side plate is provided with limiting grooves, and the limiting sliders and limiting grooves are slidably matched.

[0014] Preferably, the upper end of the side panel is provided with a handle.

[0015] Therefore, the present invention has the following beneficial effects:

[0016] (1) Multiple supports are set inside the box, and multi-layer breeding grid baskets are set in the supports, which can improve the space utilization and facilitate the classification and placement of snails;

[0017] (2) The bracket can be moved freely and locked by the cooperation of the lateral telescopic structure, locking pin and locking hole, which makes it easy to put and take out screws and convenient to use. Attached Figure Description

[0026] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 , Figure 2 The illustrated laboratory high-density temporary holding device for snails includes a box 1 with an open top and a lateral telescopic mechanism. Several supports 2 are spaced apart inside the box. Each support includes two opposing side panels 21 and partitions 22 spaced apart between the side panels (e.g., ...). Figure 3 As shown), the upper end of the side panel is provided with a handle 27, and the partition is provided with a flow hole 24. The space between adjacent partitions forms a placement chamber 23 for placing the breeding mesh basket (as shown). Figure 4 As shown), the guide rail is fixed to the outer side of the side panel. A pull-out aquaculture grid basket 3 is installed inside the room. Limiting sliders 25 are fixed to both sides of the aquaculture grid basket. Limiting grooves 26 are provided on the inner side of the side panel. The limiting sliders and limiting grooves are slidably matched (e.g., ...). Figure 7 As shown), the inner wall of the housing is provided with several opposing guide grooves 4, and the outer side of the bracket is fixed with guide rails 5 that are adapted to the guide grooves. Several locking holes 6 are provided longitudinally on the guide rails (such as...). Figure 6 As shown), the lateral telescopic structure is set on both sides of the box body. The lateral telescopic mechanism includes a U-shaped frame 8, a movable plate 9, and a conical head 10 set on one side of the box body. The movable plate is located on the outer side of the box body on both sides of the U-shaped frame. Guide rods 17 are fixed on both sides of the box body. The guide rods pass through the movable plate. Limit baffles 18 are fixed to the outer ends of the guide rods. Fixed plates 19 are fixed on the movable plate (as shown). Figure 5As shown), a locking pin 7 that can be inserted into the locking hole is fixed on the fixed plate. The end face of the locking pin is spherical, and the conical head is located inside the U-shaped frame. Ball heads 11 are provided on both sides of the conical head. A connecting rod 12 that passes through the U-shaped frame and slides with the U-shaped frame is fixed on the ball head. A guide sleeve 20 is fixed on the outside of the side plate of the U-shaped frame. The connecting rod passes through the guide sleeve and slides with the guide sleeve. The outer end of the connecting rod is fixedly connected to the moving plate. The locking pin is fixed on the moving plate. A retaining spring 13 is sleeved on the part of the connecting rod between the U-shaped frame and the ball head. The ball head contacts the inclined surface of the conical head under the action of the retaining spring. A pull rod 14 is fixed on the conical head. The pull rod passes through the U-shaped frame and slides with the U-shaped frame. A handle 15 is fixed on the outer end of the pull rod. A spring 16 is sleeved on the part of the pull rod between the U-shaped frame and the handle.

[0028] The method of using this invention is as follows: When placing snails for temporary care, pull the lever outward to compress the spring. The beveled surface of the conical head presses the ball head outward, thereby causing the connecting rod to move the locking pins located on both sides of the box outward simultaneously until they exit the locking holes. Once the guide rail on the bracket can move along the guide groove, lift the bracket upward to raise the breeding mesh basket for placing snails to a suitable height (e.g., Figure 1 As shown in the diagram, release the lever to insert the locking pin into the corresponding locking hole, and the bracket will be fixed relative to the box. After pulling out the breeding mesh basket, place the snails into the breeding mesh basket. After placing them, push the breeding mesh basket back into place to reset it. Pull the lever outward to compress the spring. The beveled surface of the conical head will press the ball head outward, thereby causing the connecting rod to move the locking pins located on both sides of the box outward simultaneously until they exit the locking hole. After the bracket and the breeding mesh basket fall back into the box under the action of gravity, release the lever. The method of taking out snails is the same as the method of placing them.

[0029] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
