Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a portable handheld atmospheric sampling device. Background Technology

[0002] Atmospheric sampling is a fundamental task in fields such as environmental monitoring, occupational health, and scientific research. It is used to collect gaseous or particulate pollutants in the air for subsequent analysis. To meet the portability requirements of the device, existing atmospheric sampling devices are usually designed with a flip-up, retractable grip to reduce the overall size and facilitate carrying when not in use. However, most of these grips rely solely on the friction between the grip and the main body of the sampling device for positioning. This method of positioning is unstable, and the grip is prone to accidental flipping due to accidental touches or vibrations during carrying or use, seriously affecting the ease of operation and the stability of the sampling process. In addition, existing grips are generally just a single flip-up rod structure without any protective components to enhance hand grip stability. Under conditions of prolonged gripping, sweaty hands, or unstable force, the grip is very likely to slip off the operator's hand, causing the entire device to fall. Therefore, there is an urgent need for a portable handheld atmospheric sampling device. Utility Model Content

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: It includes an atmospheric sampler body 1 and a sampling bottle 2. The sampling bottle 2 is connected to the air outlet at the lower left side of the atmospheric sampler body 1, and an air inlet pipe 13 is connected to the air inlet at the upper left side of the atmospheric sampler body 1. The air inlet pipe 13 is a telescopic structure. By utilizing the telescopic structure of the air inlet pipe 13, the space occupied by the air inlet pipe 13 during carrying can be reduced, thereby further improving the portability of the device. It also includes: A fixed rod 3 is fixedly installed in a storage slot 4 at the bottom of the atmospheric sampler body 1. A support rod 5 is rotatably mounted on the fixed rod 3 via a bearing. Anti-detachment frames 6 are inserted on both the front and rear sides of the support rod 5. A self-retracting mechanism 7 connected to the anti-detachment frames 6 is provided inside the support rod 5. Two limiting frames 14 are fixedly installed on the anti-detachment frames 6, and the limiting frames 14 are abutted against inside the support rod 5. The limiting frames 14 can limit the anti-detachment frames 6 on the support rod 5 to prevent the anti-detachment frames 6 from falling off the support rod 5. A rubber sleeve 15 is fixedly mounted on the support rod 5 at the inner position of the anti-detachment frames 6. The outer ring wall of the rubber sleeve 15 is provided with anti-slip texture. The rubber sleeve 15 can increase the friction generated when the operator's hand holds the support rod 5, thereby fully improving the handheld stability of the device. The control plate 8 is movably disposed in the connecting groove 9 opened at the lower end of the support rod 5. A pull handle 16 is fixedly provided at the bottom of the control plate 8. By pulling the handle 16, it is easier for the staff to apply force to the control plate 8 by hand, thus improving the ease of operation. Limiting rods 10 are fixedly provided on both the left and right sides of the upper part of the control plate 8, and the limiting rods 10 are movably inserted into the support rod 5. Limiting grooves 11 that cooperate with one end of the limiting rods 10 are opened on the inner top wall and the left inner wall of the storage groove 4. Spring 12 is fixedly mounted on the inner top wall of the connecting groove 9, and the lower end of spring 12 is fixedly connected to the control plate 8. The self-closing mechanism 7 includes: The first bevel gear 7-1 is fixedly sleeved on the fixed rod 3. The support rod 5 has a rotating rod 7-2 rotatably installed inside the rod 5 via a bearing. The upper end of the rotating rod 7-2 is fixedly sleeved with a second bevel gear 7-3 that meshes with the first bevel gear 7-1. Two spur gears 7-4 are fixedly mounted on the rotating rod 7-2. Two racks 7-5 are fixedly mounted on the anti-detachment frame 6. The spur gears 7-4 mesh with the racks 7-5 on the two anti-detachment frames 6. The anti-detachment frame 6 has slots 7-6 that cooperate with the racks 7-5. During the process of the support rod 5 flipping to the storage slot 4, the self-storage mechanism 7 can be used to move the anti-detachment frame 6 inward to the support rod 5, reducing the space occupied by the storage slot 4 in the atmospheric sampler body 1.

[0018] When using this utility model, the operator holds the support rod 5 to operate the device by hand, and the two anti-drop brackets 6 also provide physical restraint for the operator's hands, reducing the risk of the device falling. During use, the connecting slot 9 can also be connected to external support components such as a portable tripod to enable the device to be used in a fixed position. After sampling is completed, the pull handle 16 can be pulled down, causing the control plate 8 to move the limiting rod 10 downward and stretch the spring 12, so that the upper end of the limiting rod 10 moves out of the limiting groove 11 on the inner top wall of the connecting slot 9. Then, the support rod 5 is flipped into the storage slot 4. During this process... The rotating rod 7-2 also flips, and by meshing with the first bevel gear 7-1 and the second bevel gear 7-3, the second bevel gear 7-3 drives the rotating rod 7-2 to rotate. The rotating rod 7-2 drives the spur gear 7-4 to rotate, and the spur gear 7-4 drives the racks 7-5 on both sides to move in opposite directions synchronously. The racks 7-5 drive the anti-detachment frame 6 to move into the support rod 5. Then, the pull handle 16 is released, so that the spring 12 returns to its original position and shortens, and drives the limit rod 10 to move through the control plate 8. One end of the limit rod 10 is inserted into the limit groove 11 on the inner wall of the left side of the connecting groove 9 to achieve the limit of the support rod 5 in the retracted state.

[0019] Compared with the prior art, the beneficial effects of this utility model are: The rubber sleeve 15 on the support rod 5, combined with the anti-slip texture, can increase the friction when the hand is gripping it, and the anti-slip brackets 6 on both sides can limit the worker's hand, reducing the risk of the device falling through double protection; By utilizing the engagement of the limiting rod 10 with the limiting grooves 11 at different positions in the storage groove 4, as well as the cooperation of the control plate 8 and the spring 12, not only can the stability of the support rod 5 be ensured during use, but also accidental flipping caused by vibration or contact during storage or carrying can be avoided, thus improving operational reliability. The lower end of the support rod 5 can be connected to external support components such as a portable tripod through the connecting slot 9, so that the device can be flexibly moved and sampled by hand, and can also be sampled stably in a fixed position. This adapts to different needs in environmental monitoring, such as outdoor mobile sampling and continuous sampling at fixed points, and improves the practicality and scenario adaptability of the device. During the process of the support rod 5 flipping into the storage slot 4, the anti-detachment frame 6 can be moved inward to the support rod 5 by the self-storage mechanism 7, thereby reducing the space occupied by the storage slot 4 on the atmospheric sampler body 1.

[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
