Description

Technical Field

[0001] This utility model relates to the technical field of quadrupole cleaning, and in particular to a quadrupole clamping pliers. Background Technology

[0002] In mass spectrometry systems, the quadrupole mass analyzer is one of the most widely used core components, renowned for its compact structure, fast scanning speed, high cost-effectiveness, and excellent stability. The four precision electrodes of the quadrupole are susceptible to ion deposition, organic residue, or particulate contamination, leading to electric field distortion, decreased resolution, signal drift, and even loss of sensitivity. Therefore, regular and standardized maintenance and cleaning are necessary to maintain the long-term stability and accuracy of the quadrupole. When performing maintenance and cleaning, the quadrupole needs to be removed from the instrument. Currently, most maintenance personnel remove it by hand. Because the gap between the cavity housing the quadrupole and the quadrupole itself is very small, this process is inconvenient and may even damage the quadrupole. Utility Model Content

[0018] The present invention will be further described in detail below with reference to the embodiments.

[0019] refer to Figures 1-5 This utility model provides a four-pole clamp, including a clamp body, a first clamp head assembly, a second clamp head assembly, and a silicone ring 5 with an opening.

[0020] The clamping pliers body includes a first clamping body 1 and a second clamping body 2 that rotate and engage with each other. The first clamping body 1 has a first mounting part 11, a first mating part 12, and a first handhold part 13. The second clamping body 2 has a second mounting part 21, a second mating part 22, and a second handhold part 23. The first mating part 12 and the second mating part 22 are connected by a pin, allowing the first clamping body 1 and the second clamping body 2 to rotate and engage with each other. The first handhold part 13 and the second handhold part 23 correspond left and right and are both provided with anti-slip textures. The top of the first mounting part 11 and the second mounting part 12 are both provided with a hollow section 14, and the side wall of the hollow section 14 is provided with a locking hole. The shape and position of the locking hole match the shape and position of the locking block 31. The inner diameter of the hollow section 14 matches the diameter of the first rod 31 and the second rod 41, facilitating the insertion of the first rod 31 and the second rod 41 into the hollow section 14 during clamping.

[0021] The first clamping head assembly includes two first clamping heads 3. Each first clamping head 3 has a locking block 31, a spring 32, a first rod body 33, and an arc-shaped clamping arm 34. The first rod body 33 has a receiving groove 35, in which the spring 32 is installed. The bottom of the locking block 31 is installed in the receiving groove 35 and fixedly connected to the spring 32. The top of the locking block 31 protrudes from the receiving groove 35 and is located on the outer surface of the first rod body 33. The shape and position of the locking block 35 match the shape and position of the locking hole 15, facilitating smooth locking of the locking block 31 into the locking hole 15 during installation. The arc-shaped clamping arm 34 is located at the end of the first rod body 33 furthest from the locking block 31 and is vertically fixedly connected to the first rod body 33. The surface of the arc-shaped clamping arm 34 is covered with a silicone layer, and the surface of the silicone layer has anti-slip textures. The silicone layer on the surface of the arc-shaped clamping arm 34 protects the quadrupole during clamping, preventing damage to the quadrupole surface caused by the arc-shaped clamping arm 34.

[0022] Two first clamping heads 3 are inserted one-to-one into the hollow sections 14 of the first mounting part 11 and the second mounting part 21. Two locking blocks 31 are locked one-to-one into the locking holes of the first mounting part 11 and the locking holes 15 of the second mounting part 21, so that the two arc-shaped clamping arms 34 are in a relative position. The clamping space formed when the two opposing arc-shaped clamping arms 34 are closed matches the rod portion of the quadrupole.

[0023] The second jaw assembly includes two second jaws 4. Each second jaw 4 sequentially comprises a locking block 31, a spring 32, a second rod 41, and a connecting post 42. The second rod 41 has a receiving groove 35, within which the spring 32 is installed. The bottom of the locking block 31 is installed within the receiving groove 35 and fixedly connected to the spring 32. The top of the locking block 31 protrudes beyond the receiving groove 35 and is located on the outer surface of the second rod 41. The shape and position of the locking block 31 match the shape and position of the locking hole 15. The connecting post 42 is located at the end of the second rod 41 furthest from the locking block 31, integrally connected to the second rod 41, and located inside the top of the second rod 41.

[0024] The silicone ring 5 has two integrally connected insertion rings 52 at both ends of its ring body 51. Two insertion posts 42 are inserted into the two insertion rings 52 one-to-one. The diameter of the insertion posts 42 matches the inner diameter of the insertion rings 52. The inner side of the ring body 51 has anti-slip texture.

[0025] In use, the two first clamp heads 3 are installed one-to-one in the hollow sections 14 of the first mounting part 11 and the second mounting part 21. The user holds the first hand-held part 13 and the second hand-held part 23, opens the first clamp body 1 and the second clamp body 2 to both sides, and the two arc-shaped clamping arms 34 open. The two arc-shaped clamping arms 34 are moved to one end of the quadrupole, so that the two arc-shaped clamping arms 34 are located on both sides of the end of the quadrupole. Then the two opposing arc-shaped clamping arms are closed to clamp the quadrupole, and then the quadrupole is removed from the instrument.

[0026] Another way to use this device is to install the two second clamp heads 4 one-to-one in the hollow section 14 of the first mounting part 11 and the hollow section 14 of the second mounting part 21, and insert the two plug pins 42 one-to-one into the two plug rings 52 of the silicone ring 5. The user holds the first hand-held part 13 and the second hand-held part 23, opens the first clamp body 1 and the second clamp body 2 to both sides, opens the ring body 51 of the silicone ring 5, moves the silicone ring 51 to the quadrupole accessory, so that the ring body 51 is fitted on the quadrupole, and then closes the first clamp body 1 and the second clamp body 2, so that the two plug pins 42 close and clamp the silicone ring 5, thereby clamping the quadrupole, and then remove the quadrupole from the instrument.

[0027] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
