Description

Technical Field

[0001] This application relates to the field of sampling device technology, and in particular to a safe sampling mechanical handle. Background Technology

[0002] In the production and preparation of various coatings, in addition to certain parameters that can be detected online, many other parameters must be sampled and tested. With the current shift towards water-based coatings, most coatings pose less harm to the human body. However, some specialty coatings (and of course, certain solvents and chemical raw materials) require minimizing direct contact with the human body. Therefore, for these types of coatings, a sampling handle is needed for sampling, using the handle to hold the coating sampling container.

[0003] A Chinese patent with authorization publication number CN221020983U discloses a safe sampling mechanical handle, which includes grippers for holding a sampling container, an extension arm, a handle, and a protective plate. The grippers are fixedly installed on the extension arm, the handle is fixedly installed on the end of the extension arm away from the grippers, and the protective plate is fixedly installed on the extension arm and located between the grippers and the handle. A pulling component for controlling the retraction of the grippers is installed on the handle. The protective plate separates the holding part from the gripping part of the paint sampling container, thereby reducing paint splashes onto the hand holding part during sampling or transportation and reducing direct contact between paint and the human body.

[0004] The aforementioned technologies have the following drawbacks: In addition to certain scenarios where splashing occurs, such as when developing new coating products, it is difficult to avoid reactions in certain systems. For example, systems containing concentrated acids are not only prone to generating heat but also to producing acid mist, which is difficult to effectively protect against through protective plates, and therefore needs to be improved. Utility Model Content

[0005] To reduce the risk of injury to sampling personnel from acid mist and other hazards during the sampling process, this application provides a safe sampling mechanical handle.

[0006] A safe sampling mechanical handle includes a gripper, an extension arm, and a handle connected in sequence. The extension arm is connected to a protective plate and an air guide shroud. The air guide shroud is located between the protective plate and the gripper, forming an air guide channel between the air guide shroud and the protective plate. The air guide shroud is connected to a gas collection pipe that communicates with the air guide channel. The extension arm is connected to a processing bottle. The gas collection pipe communicates with the processing bottle. The processing bottle is filled with packing material. A gas collection pump for drawing air into the processing bottle is provided between the gas collection pipe and the processing bottle. The processing bottle is provided with an exhaust port.

[0007] By adopting the above technical solution, the gripper, extension arm and handle are connected in sequence to realize basic sampling operations. The protective plate plays a preliminary separation role and reduces paint splashing onto the gripping part. The air guide hood is located between the protective plate and the gripper. The air guide hood and the protective plate form an air guide channel. With the help of the gas collection pipe and gas collection pump, harmful gases such as acid mist are drawn into the treatment bottle. The packing material in the treatment bottle treats the harmful gases and finally discharges them through the exhaust port, thereby reducing the damage to the sampling personnel caused by acid mist and other scenes during the sampling process.

[0008] Preferably, the air guide hood includes two symmetrically arranged half-hoods, each half-hood having a half-arm hole and a half-pipe hole. The two half-arm holes form a channel for an extension arm to pass through, and the two half-pipe holes form a channel for an air collection pipe to pass through. The two half-hoods are detachably connected.

[0009] By adopting the above technical solution, the air guide cover adopts two symmetrically arranged half covers, and the half covers are provided with half arm holes and half pipe holes for the extension arm and the air collection pipe to pass through respectively. The half covers can be detachably connected, which facilitates the installation and disassembly of the air guide cover and makes it easy to maintain and replace parts.

[0010] Preferably, a sealing ring is provided at the connection between the air collection pipe, the extension arm and the air guide shroud.

[0011] By adopting the above technical solution, the gas collection pipe, extension arm and air guide hood adopt a symmetrical half-cover structure that can be detachably connected for easy assembly. The sealing ring at the connection can prevent gas from leaking from the connection gap, improve the air sealing of the air guide channel, and thus ensure the effect of gas collection and treatment of harmful gases such as acid mist.

[0012] Preferably, the outer edge of the sealing ring at the end of the gas collecting pipe is provided with an anti-detachment ring groove, and the inner wall of the half-pipe hole is provided with an anti-detachment strip, which is inserted into the anti-detachment ring groove.

[0013] By adopting the above technical solution, a sealing ring is set at the connection between the gas collecting pipe, the extension arm and the air guide shroud to prevent gas leakage. An anti-detachment ring groove is set on the outer edge of the sealing ring at the end of the gas collecting pipe, and an anti-detachment clip is set on the inner wall of the half-pipe hole and inserted into the anti-detachment ring groove. This can further enhance the connection stability between the gas collecting pipe and the air guide shroud, prevent the sealing ring from falling off and ensure the sealing effect.

[0014] Preferably, the extension arm is connected to a ball-head connecting rod, and the processing bottle is provided with a ball-and-socket connecting rod, and the ball-head connecting rod and the ball-and-socket connecting rod are rotatably connected.

[0015] By adopting the above technical solution, the extension arm is connected to the ball joint rod, and the treatment bottle is equipped with a ball socket rod, with the two rotatably connected. This allows the treatment bottle to rotate flexibly relative to the extension arm, automatically adjusting its position and angle to adapt to different sampling scenarios and operational needs. When the holding part needs to be rotated slightly during operation, the treatment bottle can still be automatically kept vertical, thereby reducing packing shaking or even overflow caused by bottle swaying.

[0016] Preferably, the treatment bottle includes a cap and a bottle body, the cap and the bottle body are threaded together, and the cap is connected to a ball-and-socket connecting rod.

[0017] By adopting the above technical solution, the treatment bottle consists of a cap and a bottle body connected by threads, which makes it easy to disassemble the treatment bottle to replace the internal packing. At the same time, the cap is connected to the ball joint rod, which can cooperate with the ball joint rod to realize the rotation adjustment of the treatment bottle relative to the extension arm, making the whole device more flexible to use.

[0018] Preferably, activated carbon is provided at the exhaust port.

[0019] By adopting the above technical solution and placing activated carbon at the exhaust port, the gas discharged from the treatment bottle can be further purified, the treatment effect of harmful gases can be improved, and the sampling personnel can be better protected.

[0020] Preferably, the packing material is a neutralizing liquid, the bottom of the gas collecting pipe extends into the bottom of the neutralizing liquid and is connected to a coil, and the coil is provided with several vent holes.

[0021] By adopting the above-mentioned technical solutions, for example, an alkaline neutralizing liquid can be used to neutralize acid mist. The acid mist, along with air, is drawn to the bottom of the neutralizing liquid and then discharged through several vents, increasing the contact area between the acid mist and the neutralizing liquid, thereby improving the neutralization effect. The acid mist after neutralization treatment has reduced acidity, thus achieving a certain level of protection compared to directly inhaling acid mist.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By connecting the air guide hood, gas collection pipe, treatment bottle and gas collection pump to the extension arm, the acid mist and other harmful gases generated during the sampling process can be drawn into the treatment bottle, reducing the damage to sampling personnel caused by acid mist and other situations. 2. The air guide cover consists of two detachable half-covers, making it easy to install and remove the air guide cover; 3. A sealing ring is installed at the connection between the gas collection pipe, the extension arm and the air guide shroud to reduce gas leakage and improve the protection effect.

[0025] The technical solutions in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0026] This application mainly adopts the method of setting up a wind guide hood, a gas collection pipe and a treatment bottle to purify acid mist, thereby reducing the damage caused to sampling personnel by acid mist during the sampling process. The following is a further detailed description of this application. Example

[0027] The safe sampling mechanical handle provided in this application embodiment includes a gripper 1, an extension arm 11, and a handle 12 connected in sequence. Specifically, the gripper 1 is used to hold the sampling container. It can be a structure similar to the mechanical grippers 1 commonly found in the prior art, such as a gripper 1 made of elastic material that relies on its own elastic deformation to hold the sampling container; or it can be a gripper 1 that is controlled to retract by a mechanical linkage device, like the jaws of pliers. The gripper 1 typically has good wear resistance and corrosion resistance to adapt to long-term use and various chemical environments.

[0028] The extension arm 11 connects the gripper 1 and the handle 12, and also provides a mounting base for other components. It is typically a slender rod-like structure, which can be made of metal, such as stainless steel, to ensure sufficient strength and durability; or it can be made of high-strength plastic to reduce overall weight. The surface of the extension arm 11 can be smoothed to reduce the adhesion of acid mist and other contaminants.

[0029] The grip 12 is the part for the operator to hold. To improve grip comfort and stability, a non-slip rubber layer can be wrapped around its surface. The rubber layer has a soft texture that conforms to the hand and prevents the handle from slipping and falling.

[0030] Reference Figure 1 The extension arm 11 is connected to a protective plate 13 and an air guide shroud 2. The air guide shroud 2 is located between the protective plate 13 and the gripper 1, forming an air guide channel 20 between them. The protective plate 13 is fixed to the extension arm 11 and serves to prevent paint splatter. It is usually a flat plate structure, made of transparent plexiglass, which allows the operator to observe the sampling process while effectively blocking paint. The protective plate 13 is bolted to the extension arm 11 for easy disassembly and replacement.

[0031] The air guide hood 2 is connected to a gas collecting pipe 3 that communicates with the air guide channel 20. The extension arm 11 is also connected to a treatment bottle 4, which is filled with packing material 41. The gas collecting pipe 3 is connected to the treatment bottle 4, and a gas collecting pump 42 is installed between the gas collecting pipe 3 and the treatment bottle 4 to draw air into the treatment bottle 4. The treatment bottle 4 is equipped with an exhaust port 43. This structure allows harmful gases such as acid mist to enter the treatment bottle 4 through the air guide channel 20 and the gas collecting pipe 3, be treated by the packing material 41, and then be discharged, effectively reducing the damage of acid mist to sampling personnel.

[0032] Reference Figure 2 The air guide shroud 2 includes two symmetrically arranged half-shrouds 21. Each half-shroud 21 has a half-arm hole 22 and a half-pipe hole 23. The two half-arm holes 22 form a channel for the extension arm 11 to pass through, and the two half-pipe holes 23 form a channel for the air collecting pipe 3 to pass through. The two half-shrouds 21 are detachably connected. The detachable connection between the two half-shrouds 21 can be achieved by snap-fit, making installation and disassembly convenient. The half-shrouds 21 can also be made of plastic and manufactured through injection molding, which has the advantages of being lightweight and low-cost. The joint between the two half-shrouds 21 can be designed as a sealing structure, such as using a rubber sealing strip, to enhance the sealing performance of the air guide shroud 2.

[0033] Reference Figure 2 and Figure 3A sealing ring 24 is provided at the connection points of the gas collecting pipe 3, the extension arm 11, and the air guide shroud 2. The outer edge of the sealing ring 24 at the end of the gas collecting pipe 3 is provided with an anti-detachment groove 26, and an anti-detachment retaining strip 25 is provided on the inner wall of the half-pipe hole 23, which is inserted into the anti-detachment groove 26. The sealing ring 24 can be made of rubber, which has good elasticity and sealing performance. It can prevent gases such as acid mist from leaking from the connection points, further improving the overall system's sealing performance. The design of the anti-detachment groove 26 and the anti-detachment retaining strip 25 enhances the stability of the sealing ring 24, preventing it from falling off during use.

[0034] By incorporating a sealing ring 24 and an anti-detachment structure, the sealing performance at the connection between the gas collecting pipe 3, the extension arm 11, and the air guide shroud 2 is further improved, reducing the leakage of harmful gases such as acid mist and further ensuring the safety of sampling personnel. In actual use, even when the handle is operated at different angles or subjected to certain vibrations, the sealing ring 24 can function stably, effectively improving the reliability and safety of the handle.

[0035] Reference Figure 4 The gas collecting pipe 3 is used to transport harmful gases such as acid mist from the air guide duct 20 to the treatment bottle 4. It can be a flexible hose for easy adjustment or a rigid pipe, such as a metal pipe, for better corrosion resistance and strength. The connection between the gas collecting pipe 3 and the air guide hood 2 and the treatment bottle 4 must be sealed to prevent gas leakage.

[0036] The treatment bottle 4 is a key component for treating harmful gases such as acid mist. It includes a cap 45 and a bottle body 46, with a threaded connection between the cap 45 and the bottle body 46 for easy opening to add or replace the filler 41. Furthermore, in this embodiment, the cap 45 is connected to a ball-and-socket connecting rod 48, and correspondingly, the extension arm 11 is connected to a ball-head connecting rod 47, which is rotatably connected to the ball-and-socket connecting rod 48. This rotatable connection allows the treatment bottle 4 to automatically and flexibly adjust its angle to maintain verticality, adapting to different usage scenarios. The treatment bottle 4 can be made of glass or plastic, and must have good corrosion resistance.

[0037] The packing material 41 is a neutralizing liquid, such as sodium hydroxide solution, which can neutralize acid mist. The bottom of the gas collecting pipe 3 extends into the bottom of the neutralizing liquid and is connected to a coil 31, which has several vent holes 32. The design of the coil 31 increases the contact area between the gas and the neutralizing liquid, improving the treatment effect. The vent holes 32 can be evenly distributed on the coil 31, allowing the gas to be evenly dispersed in the neutralizing liquid.

[0038] The gas collecting pump 42 provides power for the flow of gas. It can be a small electric air pump with small size and low power consumption. The air inlet of the gas collecting pump 42 is connected to the gas collecting pipe 3, and the air outlet is connected to the treatment bottle 4, continuously drawing gas from the air guide channel 20 into the treatment bottle 4.

[0039] Activated carbon 44 is installed at the exhaust port 43. Activated carbon 44 has an adsorption function, which can further filter residual harmful gases and odors. Activated carbon 44 can be in granular form and filled into the filter screen of exhaust port 43 for easy replacement.

[0040] The implementation principle of this embodiment is as follows: During the sampling process, when harmful gases such as acid mist are generated, the gas collecting pump 42 is activated, drawing the acid mist into the gas collecting pipe 3 through the air guide channel 20. The acid mist enters the treatment bottle 4 along with the air and is evenly dispersed in the neutralizing liquid through the exhaust port 32 on the coil 31. The neutralizing liquid reacts with the acid mist, reducing its acidity. In addition, the gas after neutralization is further filtered by the activated carbon 44 at the exhaust port 43 before being discharged. This effectively reduces the harm of acid mist to sampling personnel. At the same time, the rotatable connection of the ball joint rod 47 and the ball socket rod 48, as well as the detachable structure of the two halves of the air guide cover 2 21, make the handle more flexible and convenient to use and maintain, representing a significant improvement and enhancement compared to the prior art.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
