Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of indoor air detection, and specifically relates to an atmosphere collection box for indoor air detection. Background Art
[0002] Indoor air testing mainly tests the content of formaldehyde, VOC (volatile organic compounds), TVOC (total volatile organic compounds), benzene, toluene, and xylene. The collection is mainly carried out using an atmospheric collector (or air detector) and a sampling tube. The indoor air is sampled by the atmospheric collector and loaded into the sampling tube, and then taken back to the laboratory for testing and analysis to obtain indoor air test data.
[0003] At present, sampling tubes are all stored in a collection box, and multiple sampling tubes are arranged on the cover of the collection box. However, when sampling air indoors, it is usually necessary to sample in different rooms and different locations in the same room. The current practice is to label the sampling tubes. Since the cross-sectional area of the sampling tubes themselves is small, it is troublesome to label the sampling tubes. At the same time, the handwriting on the labels is easily unclear due to accidental contact during the writing process, which results in a longer time spent on labeling the sampling tubes.
[0004] More importantly, the sampling tubes used for indoor air testing are made of stainless steel, and the quality of the labels themselves varies. The labels often fall off the sampling tubes due to insufficient viscosity, necessitating re-sampling. Some labels are difficult to tear off due to excessive viscosity. Utility Model Content
[0005] In order to solve the problem that labels are easily detached from sampling tubes and cause confusion, the utility model provides an atmosphere collection box for indoor air detection, which has a marking function while storing sampling tubes. Therefore, there is no need to stick labels on the sampling tubes during use, thus avoiding the problem of confusion caused by label falling off; at the same time, it also avoids the cumbersome problems caused by sticking, writing and tearing labels.
[0006] In order to solve the technical problem, the technical solution adopted by the utility model is:
[0007] An atmospheric collection box for indoor air detection comprises a box body and a cover body, the interior of the cover body is used to place multiple sampling tubes, and is characterized in that the cover body is provided with multiple hollow strip protrusions, and a clamping space for clamping a sampling tube is formed between two adjacent strip protrusions, two locking pins are installed in the strip protrusions, and the two locking pins are connected to each other via a lightweight plate, each locking pin is equipped with a pre-tightening spring, and a locking pin hole that is compatible with the locking pin is opened on the side wall of the strip protrusion; a support seat is also installed on the cover body, and a lightweight rod is installed on the support seat, and the lightweight rod is provided with paddles with the same number as the strip protrusions, and the paddles can extend into the space between the lightweight plate and the locking pin hole and contact the lightweight plate, and a locking rod is also installed on the paddle, and a through hole that is compatible with the locking rod is opened on the side wall of the strip protrusion.
[0008] In some embodiments, the distance between the position of the locking pin hole and the bottom of the clamping space and the radius of the sampling tube are matched to each other, and the position of the through hole is higher than the position of the locking pin hole.
[0009] In some embodiments, the lightweight rod is capable of rotating on the support base.
[0010] In some embodiments, a rotating handle is formed on or connected to one end of the lightweight rod.
[0011] In some embodiments, a rotating handle is sleeved on one end of the lightweight rod, and the rotating handle can slide on the lightweight rod.
[0012] In some embodiments, retaining rings are provided at both ends of the lightweight rod, and return springs are provided between the retaining rings at both ends of the lightweight rod and the support seat, and the force applied to the lightweight rod by the preload spring is greater than the force applied to the lightweight rod by the return spring.
[0013] In some embodiments, a label column or a writing column is provided on the cover body at a position corresponding to each clamping space.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] The collection box of the utility model utilizes the structure on the cover body to automatically mark each sampling tube with a label, so there is no need to label or tear off each sampling tube, which solves the problem of confusion and cumbersomeness of sampling tubes caused by label shedding, label tearing, and label intactness, and greatly improves the efficiency of gas sampling.
[0016] At the same time, during the use of the utility model, the mode of taking a sampling tube and putting the sampling tube in before taking the remaining sampling tubes can be fundamentally prevented from mixing up the sampling tubes. In addition, in some occasions (such as cleaning the sampling tubes), the utility model can also achieve the removal of all sampling tubes by adjusting the lightweight rod, thereby improving the convenience of the utility model in use.

DETAILED DESCRIPTION
[0026] The present invention is further described below in conjunction with the embodiments, which are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the protection scope of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0028] Combined with Figure 1 The sampling tube 01 is generally made of stainless steel. Both ends of the sampling tube 02 are equipped with sealing covers 02 for sealing the two ends of the sampling tube 01. The sampling tube 01 is a prior art product, which can be understood by technicians in this field and will not be described here.
[0029] In conjunction with the accompanying drawings, the utility model of the atmospheric collection box for indoor air detection includes a box body 1 and a cover body 2, wherein the cover body 2 is hinged to the box body 1, and the cover body 2 and the box body 1 are detachably connected by a buckle 102, so as to facilitate the opening of the cover 2. A handle 101 is also provided on the box body 1 to facilitate lifting the entire collection box. Those skilled in the art can understand and comprehend it, and no further details are given here. The interior of the cover body 2 is used to place a plurality of sampling tubes 01, and a plurality of hollow strip-shaped protrusions 3 are provided on the cover body 2. A clamping space for clamping a sampling tube 01 is formed between two adjacent strip-shaped protrusions 3. Two locking pins 31 are installed in the strip-shaped protrusions 3. The two locking pins 31 are connected to each other via a lightweight plate 34. Each locking pin 31 is equipped with a preload spring 32. A locking pin hole 33 that matches the locking pin 31 is provided on the side wall of the strip-shaped protrusion 3. A support is also installed on the cover body 1. The support seat 35 is provided with a lightweight rod 36, wherein the lightweight rod 36 is installed on two support seats 35, and the lightweight rod 36 is supported by the two support seats 35, and the lightweight rod 36 is provided with paddles 37 having the same number as the strip-shaped protrusion 3, and the paddles 37 can extend into the space between the lightweight plate 34 and the locking pin hole 31 and contact the lightweight plate 34, and a locking rod 38 is also installed on the paddles 37, and a through hole 39 which is adapted to the locking rod 38 is opened on the side wall of the strip-shaped protrusion 3.
[0030] In the specific implementation process, a partition 6 is provided on the cover body 2, and the partition 6 is used to separate the cover body 2 into two cavities. The strip protrusion 3 and the sampling tube 01 are arranged in the cavity of the cover body 2 facing the box body 1, that is, the strip protrusion 3 and the sampling tube 01 can be seen when the cover body 2 is opened. The light rod 36 and the support seat 35 are installed between the partition 6 and the top of the cover body 2, so that the partition 6 can be used to cover the support seat 35 and the light rod 36.
[0031] As a matter of course, in order to meet the space required for the paddle 37 to rotate with the light rod 36, a strip hole is opened on the partition corresponding to the position of the paddle. The position of the strip hole is just blocked by the strip protrusion 3.
[0032] The working process and principle of the utility model are as follows: when a sampling tube is placed in each clamping space, the locking pin is in a compressed state, and the paddle and the locking rod are in a natural state without being squeezed by the lightweight plate. When the sampling tube in one of the clamping spaces is taken away, the two locking pins in the strip-shaped protrusion pop out in the direction of the preload spring toward the clamping space (i.e., the head of the locking pin passes through a part of the locking pin hole), and the locking pin drives the paddle in the strip-shaped protrusion to move during the movement, and the paddle drives the locking rod to pass through the through hole of the strip-shaped protrusion. Since the paddle in the strip-shaped protrusion is connected to the lightweight rod, the paddle moves the entire lightweight rod, and the lightweight rod drives all the paddles to move, so that each clamping space is locked by using the locking rod on the paddle, so that the sampling tubes in the remaining clamping spaces cannot be taken out.
[0033] When the sampling tube is put back into the clamping space (i.e., the clamping space where the sampling tube was taken out before), the sampling tube squeezes the locking rod and the locking pin in turn, so that the paddle in the strip-shaped protrusion is reset, and then the entire lightweight rod and the paddles in other positions on the lightweight rod are reset, so that the locking rods in each strip-shaped protrusion are contracted and no longer block the sampling tube, so that the sampling tube in each clamping space can be taken out, so that the remaining sampling tubes can be taken after one sampling tube is taken out and put in, so that the position of the sampling tube in each position is fixed. Then, the sampling tube can be marked by using each holding space; and there is no need to label each sampling tube, so as to avoid confusion caused by label falling off. At the same time, it also reduces the process of labeling and tearing labels for each sampling tube.
[0034] In some embodiments, the distance between the position of the locking pin hole 33 and the bottom of the clamping space and the radius of the sampling tube 01 are mutually adapted, that is, the distance between the locking pin hole 33 and the partition plate and the radius 01 of the sampling tube 01 are mutually adapted. The position of the through hole 39 is higher than the position of the locking pin hole 33 (that is, the position of the through hole 39 on the strip protrusion 3 is closer to the box body 2 than the position of the locking pin hole 33). As a result, the force applied by the locking rod 38 to the sampling tube 01 is greater than the force applied by the locking pin 31 to the sampling tube 01, and the staff can easily distinguish them when using them, so the staff is reminded that the sampling tube that has been taken out must be placed in the clamping space before other sampling tubes can be taken, and finally the problem of mixing up the sampling tubes can be avoided.
[0035] In some embodiments, the position of the light rod 36 on the support seat 25 can be rotated. When the light plate can contact the paddle during the movement, it is a working state, and then the light rod is rotated so that the light plate will not contact the paddle during the movement. For example, when it is necessary to clean each sampling tube, the position of the light rod can be adjusted so that the sampling tubes in each clamping space will not be affected by the locking rod.
[0036] In some embodiments, one end of the light rod 36 is formed with or connected to a rotating handle 5. The rotating handle 5 is used to adjust the angle position of the light rod 36, thereby controlling whether the locking rod can lock the sampling tube in the clamping space.
[0037] In some embodiments, a rotating handle 5 is sleeved on one end of the light rod 36, and the rotating handle 5 can slide on the light rod 36. Therefore, when the light rod is moving, the position of the rotating handle does not change, which is convenient for operation. In the specific implementation process, since the light rod and the support seat are installed on the inner top of the cover body, in order to facilitate the operation of the rotating handle 5, a through hole for the rotating handle 5 to pass through is opened on the partition 6.
[0038] In some embodiments, retaining rings 310 are provided at both ends of the light rod 36, and return springs 311 are provided between the retaining rings 310 at both ends of the light rod 36 and the support seat 35 (that is, the return spring 311 is sleeved on the light rod 36, and the two ends of the return spring 311 are in contact with the retaining ring 310 and the support seat 33 respectively), and the force applied by the preload spring 32 to the light rod 36 is greater than the force applied by the return spring 311 to the light rod 36. During use, the position of the light rod on the support seat can be reset under the action of the return spring.
[0039] In some embodiments, a label column 4 or a writing column is provided on the cover body 2 at a position corresponding to each clamping space. When the light plate 34 is in contact with the paddle 37 during movement, since the position of each sampling tube 01 is relatively fixed, the sampling tube 01 at that position can be marked through the label column 4 or the writing column on the cover body 2. Compared with the method of directly marking the sampling tube, not only the difficulty of labeling is reduced, but also the label set in the cover body is less likely to be stained (the label on the sampling tube is more likely to be stained due to frequent handling).
[0040] In the specific implementation process, since the strip-shaped protrusion 3 is installed on the partition 6 , the label column 4 or the writing column can be set on the partition 6 .
[0041] To sum up, the collection box of the utility model utilizes the structure on the cover to automatically mark each sampling tube, so there is no need to label or tear off each sampling tube, which solves the problem of confusion and cumbersomeness of sampling tubes caused by label falling off, label tearing, or label intactness, and greatly improves the efficiency of gas sampling.
[0042] At the same time, during the use of the utility model, the mode of taking a sampling tube and putting the sampling tube in before taking the remaining sampling tubes can be fundamentally prevented from mixing up the sampling tubes. In addition, in some occasions (such as cleaning the sampling tubes), the utility model can also remove all the sampling tubes by adjusting (rotating) the lightweight rod, thereby improving the convenience of the utility model when in use.
