Description

Technical Field

[0001] This utility model relates to the technical field of water sample preservation boxes, and in particular to a water pollution sample preservation box. Background Technology

[0002] A wastewater sample preservation box is a specialized container used for storing and transporting liquid wastewater samples. Its structure includes an outer shell, an inner liner, and a sealing cap. Wastewater sample preservation boxes are used to preserve samples collected for environmental monitoring. However, traditional preservation boxes are either too large or too small. If they are too large, they are difficult to move before collection; if they are too small, the storage space is insufficient, which is not conducive to storing sample tubes.

[0003] Currently, existing technology (CN 221438840 U) discloses a wastewater sample storage box for environmental testing, including a box body. The box body has first insertion slots at its front and rear ends, with mounting holes at the bottom of the first insertion slots. The box body has a placement slot at its upper end, with second insertion slots on both sides of the placement slot. A handle slot is located in the middle of one side of the box body, and a handle is provided within the handle slot. Insertion plate structures are inserted into the first and second insertion slots of the box body. The insertion plate structure consists of a first insertion plate, a second insertion plate, a third insertion plate, a fourth insertion plate, a first connecting hole, a second connecting hole, and a second limiting hole. The front ends of the first and second insertion plates have first connecting holes. Through the cooperation between the insertion plates and the insertion slots, the storage capacity of the box is increased, which is beneficial for placing more wastewater sample tubes.

[0004] Using the above method, when removing the sample tubes, staff can only remove the wastewater sample one tube at a time, which leads to a decrease in sample removal efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a water pollution sample preservation box, which aims to solve the problem of low retrieval efficiency of existing water pollution sample preservation boxes.

[0006] To achieve the above objectives, this utility model provides a water pollution sample preservation box, including a preservation box body, multiple sample tubes, and two removal mechanisms. The removal mechanism includes a mounting frame, a transmission block, two driven blocks, two moving rods, two mating plates, and a pulling assembly.

[0007] Multiple sample tubes are disposed within the storage box body. The mounting bracket is installed within the storage box body. The transmission block is slidably connected to the mounting bracket and located within the mounting bracket. Two driven blocks are slidably connected to the mounting bracket and to the transmission block, respectively. Two moving rods are fixedly connected to the two driven blocks and located on one side of each driven block. Two mating plates are fixedly connected to the two moving rods and located on the side of the moving rods away from the driven blocks. The pulling assembly is installed on one side of the transmission block.

[0008] The pulling assembly includes a pull rod and a fixing plate. The pull rod is rotatably connected to the transmission block and passes through the mounting frame. The fixing plate is fixedly connected to the pull rod and is located around the pull rod.

[0009] The pulling assembly further includes a handle and an anti-slip sleeve. The handle is fixedly connected to the pull rod and is located on the side of the pull rod away from the transmission block. The anti-slip sleeve is fixedly connected to the handle and is located on the outside of the handle.

[0010] The retrieval mechanism further includes two positioning rods and two positioning blocks. The two positioning rods are fixedly connected to the storage box body and are located inside the storage box body. The two positioning blocks are fixedly connected to the mounting frame and are located on both sides of the mounting frame.

[0011] The retrieval mechanism further includes a locking block and a return spring. The locking block is slidably connected to the storage box body and is located on the storage box body. The return spring is fixedly connected to the locking block and the storage box body, and is located between the storage box body and the locking block.

[0012] This utility model discloses a water pollution sample preservation box. The box body provides installation conditions for multiple sample tubes and two retrieval mechanisms. Water pollution samples can be preserved through the sample tubes and the box body. When multiple sample tubes need to be retrieved at once, the pulling component is pulled. The pulling component drives the transmission block to move the rod away from the mounting frame. The transmission block drives two driven blocks to move closer to each other. The two driven blocks drive two moving rods to move closer to each other. The two moving rods drive two clamping plates to clamp the multiple sample tubes. At this time, the pulling component can be held to retrieve multiple sample tubes at once, effectively improving the sample tube retrieval efficiency and solving the problem of low retrieval efficiency in existing water pollution sample preservation boxes.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1-3 This utility model provides a water pollution sample storage box, including a storage box body 1, multiple sample tubes 2 and two removal mechanisms. The removal mechanism includes a mounting frame 3, a transmission block 4, two driven blocks 5, two moving rods 6, two mating plates 7 and a pulling assembly.

[0020] Multiple sample tubes 2 are disposed inside the storage box body 1. The mounting frame 3 is installed inside the storage box body 1. The transmission block 4 is slidably connected to the mounting frame 3 and located inside the mounting frame 3. Two driven blocks 5 are slidably connected to the mounting frame 3 and to the transmission block 4 respectively. Two moving rods 6 are fixedly connected to the two driven blocks 5 respectively and are located on one side of the two driven blocks 5 respectively. Two mating plates 7 are fixedly connected to the two moving rods 6 respectively and are located on the side of the moving rods 6 away from the driven blocks 5. The pulling assembly is installed on one side of the transmission block 4.

[0021] In this embodiment, the storage box body 1 provides installation conditions for multiple sample tubes 2 and two extraction mechanisms. Water pollution samples can be stored through the sample tubes 2 and the storage box body 1. When multiple sample tubes 2 need to be extracted at once, the pulling component is pulled. The pulling component drives the transmission block 4 to move the rod 6 away from the mounting frame 3. The transmission block 4 drives the two driven blocks 5 to move closer to each other. The two driven blocks 5 drive the two moving rods 6 to move closer to each other. The two moving rods 6 drive the two clamping plates 7 to clamp the multiple sample tubes 2. At this time, the pulling component can be held to extract multiple sample tubes 2 at once, effectively improving the extraction efficiency of the sample tubes 2, thereby solving the problem of low extraction efficiency of existing water pollution sample storage boxes.

[0022] Furthermore, the pulling assembly includes a pull rod 8 and a fixing plate 9. The pull rod 8 is rotatably connected to the transmission block 4 and passes through the mounting frame 3. The fixing plate 9 is fixedly connected to the pull rod 8 and is located around the pull rod 8.

[0023] In this embodiment, pulling the pull rod 8 can move the transmission block 4. After the fixing plate 9 moves out of the through hole on the mounting bracket 3, rotating the pull rod 8 90° can fix the pull rod 8 through the fixing plate 9 to prevent the pull rod 8 from resetting.

[0024] Furthermore, the pulling assembly also includes a handle 10 and an anti-slip sleeve 11. The handle 10 is fixedly connected to the pull rod 8 and is located on the side of the pull rod 8 away from the transmission block 4. The anti-slip sleeve 11 is fixedly connected to the handle 10 and is located on the outside of the handle 10.

[0025] In this embodiment, the lever 8 can be pulled by the handle 10, and the anti-slip sleeve 11 can increase the friction of the handle 10, thereby improving the stability when pulling the handle 10.

[0026] Furthermore, the retrieval mechanism also includes two positioning rods 12 and two positioning blocks 13. The two positioning rods 12 are fixedly connected to the storage box body 1 and are located inside the storage box body 1, respectively. The two positioning blocks 13 are fixedly connected to the mounting frame 3 and are located on both sides of the mounting frame 3, respectively.

[0027] In this embodiment, the mounting bracket 3 can be positioned by the two positioning rods 12 and the two positioning blocks 13, thereby improving the reset efficiency of the mounting bracket 3.

[0028] Furthermore, the retrieval mechanism also includes a locking block 14 and a reset spring 15. The locking block 14 is slidably connected to the storage box body 1 and is located on the storage box body 1. The reset spring 15 is fixedly connected to the locking block 14 and fixedly connected to the storage box body 1, and is located between the storage box body 1 and the locking block 14.

[0029] In this embodiment, the mounting bracket 3 has a fixing hole, and the locking block 14 can limit the mounting bracket 3 by cooperating with the corresponding fixing hole. The locking block 14 can be pushed into the corresponding mating hole by the rebound force of the reset spring 15.

[0030] When multiple sample tubes 2 need to be removed at once, pull the handle 10. The handle 10 drives the pull rod 8 to move away from the mounting frame 3. The handle 10 drives the transmission block 4 and the fixing plate 9 to move the rod 6 away from the mounting frame 3. The transmission block 4 drives the two driven blocks 5 to move closer to each other. The two driven blocks 5 drive the two moving rods 6 to move closer to each other. The two moving rods 6 drive the two fitting plates 7 to clamp the multiple sample tubes 2. Then, rotate the handle 10. The handle 10 drives the fixing plate 9 on the pull rod 8 to rotate 90° to limit the pull rod 8. Pull the locking block 14 away from the mounting frame 3. After the locking block 14 moves out of the fixing hole, the handle 10 can be held to remove multiple sample tubes 2 at once, which effectively improves the removal efficiency of the sample tubes 2 and solves the problem of low removal efficiency of existing water pollution sample storage boxes.
