AI Technical Summary
Existing liquid sampling boxes are prone to the lid popping open due to the detachment of the female fastener in complex field environments, causing the sampling tubes to fall or break. Furthermore, the hinge connection can easily cause the tubes to slide out, increasing sampling costs and time.
The system employs a dual locking mechanism consisting of an N-shaped arm, a locking hook, and a limiting block. By moving the N-shaped arm upwards with the handle, the locking hook and the limiting block lock the box body and the lid together. Combined with the locking design of the toothed plate and the engaging plate, it ensures that the box body and the lid do not separate when the female buckle is disengaged.
It effectively prevents test tubes from falling and breaking, ensuring the smooth completion of sampling work and saving time and costs.

Description
Technical Field
[0001] This utility model belongs to the technical field of environmental liquid sampling and placement boxes, specifically, it relates to an environmental liquid sampling and placement box. Background Technology
[0002] Sampling boxes are widely used in the field of testing and are mainly divided into solid sampling boxes, liquid sampling boxes, and gas sampling boxes.
[0003] Existing liquid sampling boxes mostly use a female buckle on the outside of the box and a female buckle on the lid to connect and lock the box. However, in complex field environments, the female buckle is very likely to hit an object, causing the lid to pop open, and the sampling tubes inside the box to fall or break, making the sampling work impossible to complete or delaying it, which greatly increases the cost and time of sampling.
[0004] Secondly, when the lid and body are connected by hinges, and then by female and male fasteners on the opposite side of the hinges, although the lid and body will separate when the female and male fasteners are detached, the body will become tilted, which can easily cause the test tubes inside the body to slide out.
[0005] Therefore, in order to address this problem, this utility model proposes an environmental liquid sampling and placement box. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an environmental liquid sampling box that can overcome or at least partially solve the above problems.
[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: an environmental liquid sampling and placement box, including a box body with a box cover, and further including: a handle fixedly connected to the box body, an N-shaped arm slidably connected to the handle, and locking hooks connected to both ends of the N-shaped arm; a mounting groove formed on the upper surface of the box body, a limit block fixedly connected in the mounting groove, and the locking hooks connected to the limit block; convex toothed plates symmetrically fixedly connected to the N-shaped arm, and two convex toothed plates symmetrically slidably connected to the handle, with the convex toothed plates corresponding to the meshing plates.
[0008] Preferably, a fixed stop is fixedly connected to the handle, and a first spring is fixedly connected to the fixed stop. The end of the first spring away from the fixed stop is fixedly connected to the engagement plate.
[0009] Preferably, a lever is fixedly connected to the engagement plate, and the lever has a round hole.
[0010] Preferably, a third spring is symmetrically connected inside the handle, and the end of the third spring away from the handle is fixedly connected to the N-shaped arm.
[0011] Preferably, the two ends of the N-shaped arm are fixedly connected with mounting boxes, the locking hooks are slidably connected in the mounting boxes, the second springs are connected in the mounting boxes, one end of the second spring is connected with the pull rod and the other end is connected with the locking hook, and the box body is provided with a sliding groove in the side wall of the mounting groove.
[0012] Preferably, the box body is fixedly connected with female buckles in symmetry, the box cover is fixedly connected with male buckles in symmetry, and the female buckles are locked with the male buckles.
[0013] Preferably, the box body is fixedly connected with a cross partition plate, the cross partition plate is fixedly connected with two layers of bearing plates, and the bearing plates are provided with test tube limiting holes.
[0014] Compared with the prior art, the utility model has the following beneficial effects: when the user locks the female buckle and the male buckle to lock the box body and the box cover for the first time, holds the holding plate on the handle, and makes the N-shaped arm and the locking hooks at the two ends displace upward to lock the box body and the box cover for the second time with the limiting blocks in the mounting grooves in the box body. Then the protruding tooth clamping plates displace upward to lock with the meshing clamping plates. In a complex outdoor environment, even if the female buckle and the male buckle are separated, the locking hooks and the limiting blocks can lock the box body and the box cover, avoiding the falling and breaking of the sampling test tubes. Secondly, when the box cover and the box body are connected by hinges, the female buckle and the male buckle are connected on the opposite surfaces of the hinges. Although the female buckle and the male buckle are separated, the connection between the box cover and the box body is separated, the box body is inclined, and the test tubes in the box body slide out, the device is locked for the second time, the box cover and the box body can be effectively prevented from being opened, the risk of the test tubes sliding out is avoided, the sampling time and cost are greatly saved, and the sampling work is ensured to be completed smoothly.
