DETAILED DESCRIPTION

[0021] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0022] like Figure 1-Figure 4 As shown, this embodiment provides a connection device for preventing argon leakage of a direct-reading spectrometer, including a delivery pipe 1, a connector 2 installed at the end of the delivery pipe 1, and a pressure reducing valve 3 at the other end of the delivery pipe 1, both ends of the delivery pipe 1 are provided with a positioning mechanism 4 for fixing the end of the delivery pipe 1, and the middle position of the delivery pipe 1 is provided with a pipe collecting mechanism 5 for adjusting the length of the delivery pipe 1.

[0023] General working principle: When in use, connect one end of the pressure reducing valve 3 on the delivery pipe 1 to the argon tank, and then connect the connector 2 to the connection port on the rear panel of the direct reading spectrometer. After the pressure reducing valve 3 and the connector 2 are fixed, use the positioning mechanism 4 to fix the two ends of the delivery pipe 1 in position to avoid direct pulling on the connection between the pressure reducing valve 3 and the connector 2 when the delivery pipe 1 is subjected to tension, thereby ensuring the stability of the connection and avoiding leakage of argon. In addition, according to the placement of the argon tank, the length of the delivery pipe 1 is adjusted using the pipe collecting mechanism 5 to avoid the delivery pipe 1 being dragged on the ground.

[0024] In this embodiment, protection springs 6 are fixedly provided at both ends of the delivery pipe 1 , and the delivery pipe 1 passes through the inside of the protection springs 6 .

[0025] Partial working principle: The protective springs 6 are located at both ends of the delivery pipe 1, which effectively avoid excessive bending of the connection and ensure the delivery effect of argon gas.

[0026] In this embodiment, the positioning mechanism 4 includes a fixing sleeve 7 and a fastening rope 8. The fixing sleeve 7 is fixed to the end of the conveying pipe 1. The fastening rope 8 is provided on the outside of the fixing sleeve 7. A take-up mechanism for retracting and releasing the fastening rope 8 is provided on the top of the fixing sleeve 7. A buffer mechanism is provided inside the fixing sleeve 7.

[0027] Local working principle: when fixing the end of the conveying pipe 1, the fastening rope 8 is tied to a fixed object. At this time, the end of the conveying pipe 1 has a fulcrum at the position of the fixing sleeve 7. When the conveying pipe 1 is pulled, the position of the fixing sleeve 7 and the object tied with the fastening rope 8 bear the tension, which will not cause the end of the conveying pipe 1 to loosen.

[0028] In this embodiment, the buffer mechanism includes an end cover 9 and a tension spring 10. The end cover 9 is fixed to the outside of the conveying pipe 1, and the side of the end cover 9 is fitted to the end of the fixed sleeve 7. A tension spring 10 is provided between the inner end of the fixed sleeve 7 and the end cover 9. The conveying pipe 1 is bent and arranged inside the fixed sleeve 7. The straight length of the conveying pipe 1 inside the fixed sleeve 7 is greater than the length of the fixed sleeve 7.

[0029] Local working principle: When the conveying pipe 1 is pulled, the end cover 9 will be pulled. Since a tension spring 10 is provided between the end cover 9 and the inside of the fixed sleeve 7, and the conveying pipe 1 is bent and arranged inside the fixed sleeve 7, the tension spring 10 can be used for buffering to reduce the instantaneous tension on the fixed sleeve 7.

[0030] In this embodiment, the wire-reeling mechanism includes a storage box 11, a rotating rod 12 and an adjusting block 13. The storage box 11 is fixed on the top of the fixed sleeve 7. The rotating rod 12 is vertically rotatably installed inside the storage box 11. The fastening rope 8 is wound around and installed on the rotating rod 12. There are two groups of fastening ropes 8 on the rotating rod 12. The other end of the fastening rope 8 extends to the outside of the storage box 11. The top of the rotating rod 12 is installed with an adjusting block 13, and the adjusting block 13 is attached to the top of the storage box 11.

[0031] Partial working principle: Before use, the fastening rope 8 is wound around the rotating rod 12. When in use, the bracket pulls the fastening rope 8 outward. After loosening it after use, the adjustment block 13 can still be rotated to control the rotation of the rotating rod 12, and the fastening rope 8 can be wound around the rotating rod 12 for rewinding.

[0032] In this embodiment, the tube storage mechanism 5 includes a storage tube 14, a fixing rod 15 and a cover plate 16. The storage tube 14 is fixed on the conveying tube 1, and the conveying tube 1 passes through the end of the storage tube 14. A fixing rod 15 is fixed at the middle position inside the storage tube 14, and the conveying tube 1 is wrapped around the fixing rod 15. The cover plate 16 is inserted into the end of the storage tube 14.

[0033] Partial working principle: If the length of the delivery tube 1 is long, the delivery tube 1 can be firstly wound around the fixing rod 15, and the delivery tube 1 is hidden inside the storage tube 14, and then the cover plate 16 is put on to adjust the use length of the delivery tube 1.

[0034] In this embodiment, the length of the fixing rod 15 is greater than that of the storage tube 14 , a notch is provided on the cover plate 16 for the conveying tube 1 to pass through, and a sliding hole for limiting the fixing rod 15 is provided in the middle of the cover plate 16 .

[0035] Partial working principle: The length of the fixing rod 15 is relatively long, so it is more convenient to wind the conveying tube 1, and it is more convenient to push the conveying tube 1 into the storage tube 14 during the winding process.

[0036] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
