Description

Technical Field

[0001] The utility model relates to the technical field of air detection adsorption tube experimental tools, in particular to a handheld clamp with magnetic attraction that is convenient for clamping metal samples. Background Art

[0002] The air sampling and adsorption tube experiment is a commonly used method for collecting and analyzing air samples. It uses an adsorbent to absorb pollutants from the air, then analyzes them through elution and quantification. Air samples are collected on-site and stored in a large number of adsorption tubes. These tubes are then brought back to the laboratory and individually placed into the experimental instrument for analysis.

[0003] Deficiencies in existing technology: Laboratories test certain samples by manually placing them into instrument slots, lacking specialized tools. Manual manipulation is unstable, and adsorption tube samples are made of metal, which creates low friction with the hand and can easily slip. Even simple clamping tools can cause slippage and instability.

[0004] When placing the sample, it needs to be placed accurately in the hole of the experimental instrument. The proficiency of the operators varies, and the placement efficiency is sometimes low. When placing the sample, if it is not vertically aligned with the bottom groove in the instrument hole, the sample will fall in and it will be difficult to take it out for a while, which greatly affects the experiment.

[0005] Therefore, in order to maintain the stability and accuracy of the sample when placed in the test instrument during the experiment, it is necessary to design a special tool to facilitate clamping the metal sample with a magnetic handheld clamp. Utility Model Content

[0008] One half of the clamping section is fixedly connected to the central rotating hub, and the other half is hinged to the axis inside the central rotating hub to achieve rotation.

[0009] A push-type magnetic attraction component is also provided above the clamp body. The push-type magnetic attraction component includes a magnetic attraction head located above the arc-shaped clamping section, a magnetic attraction control rod above the hand-held section, and a torsion spring. The magnetic attraction head is connected to one end of the magnetic attraction control rod via a torsion spring; the torsion spring is installed on the central rotating hub.

[0010] Under the initial torsion force of the torsion spring, the magnetic head is tightly attached to and parallel to the top of the arc-shaped clamping section, and the magnetic control rod is obliquely placed above the hand-held section. When the magnetic control rod is pressed, the magnetic head is driven to rise up and away from the arc-shaped clamping section under the action of the torsion spring.

[0011] Furthermore, a triangular connecting column is extended from the upper end of the central rotating hub described in the utility model, and the torsion spring is installed on the triangular connecting column; a magnet auxiliary gasket is extended from the front end of the central rotating hub, and the magnet auxiliary gasket is located between the magnetic suction head and the arc-shaped clamping section.

[0012] Furthermore, a rubber gasket is installed on the clamping surface inside the linear clamping section of the utility model.

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 4 The illustrated embodiment shows a magnetic handheld clamp for clamping metal samples, comprising a clamp body consisting of a clamping section, a handheld section 1, and a central rotating hub 2. The clamping section comprises two arc-shaped clamping sections 3 on the left and right, each of which has a corresponding embracing structure. A linear clamping section 4 is further provided on the outer side of the arc-shaped clamping section 3.

[0025] A push-type magnetic attraction assembly is also provided above the clamp body. The push-type magnetic attraction assembly includes a magnetic attraction head 5 located above the arc-shaped clamping section 3, a magnetic attraction control rod 6 above the hand-held section 1, and a torsion spring 7. The magnetic attraction head 5 is connected to one end of the magnetic attraction control rod 6 via the torsion spring 7. The torsion spring 7 is mounted on the central rotating hub 2.

[0026] Under the initial torsion of the torsion spring 7 , the magnetic head 5 is closely attached to and parallel to the upper side of the arc-shaped clamping section 3 , and the magnetic control rod 6 is obliquely placed above the hand-held section 1 .

[0027] Among them, a triangular connecting column 8 is extended from the upper end of the central rotating hub 2, and the torsion spring 7 is installed on the triangular connecting column 8; a magnet auxiliary gasket 9 is extended from the front end of the central rotating hub 2, and the magnet auxiliary gasket 9 is located between the magnetic head 5 and the arc-shaped clamping section 3.

[0028] A rubber gasket 10 is installed on the clamping surface inside the linear clamping section 4. A handheld section protective pad 11 is sleeved on the handheld section 1. A magnet block is built into the magnetic head 5. A logo button 12 is also provided on the magnetic control rod.

[0029] Working principle:

[0030] Step 1: Confirm that the components are intact: Confirm that the rubber gasket and the handheld section pad are intact and the central rotating hub is functioning properly to maintain a good clamping effect. Press the magnetic control lever to test the action and magnetism of the push-type magnetic assembly.

[0031] Step 2: For metal sample parts: Operate the handheld section to open the clamping section, without pressing the magnetic control lever. At this time, the magnetic head falls onto the magnetic auxiliary gasket under the initial torsion of the torsion spring. Keep the magnetic auxiliary gasket magnetic, and then place the magnetic auxiliary gasket close to the target part of the sample for adsorption;

[0032] Step 3: Maintain the magnetism to stabilize the metal sample: operate the handheld section to close the clamping section to clamp the sample. The sample is located in the arc-shaped clamping section and is clamped tightly, so that the sample can be moved stably and placed into the target part of the test instrument.

[0033] Step 4: After placing the sample in the target area of ​​the instrument, press the magnetic control lever. Under the action of the torsion spring, the magnetic head is driven to lift up and separate from the magnet auxiliary gasket, and the adsorption effect on the sample disappears. Then, the clamping section is opened and the sample is successfully separated.

[0034] Step 5: For samples that do not require magnetic clamping, you can only use the linear clamping section to clamp the sample for operation.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
