Description

Technical Field

[0001] The utility model belongs to the technical field of refrigerant tank accessories and relates to a refrigerant bottle opener. Background Art

[0002] At present, the refrigerant filling of refrigeration equipment such as air conditioners and refrigerators is generally carried out by connecting the refrigerant tank to the equipment to be filled and utilizing the pressure difference between the two. The refrigerant used in automobile air conditioners is usually stored in refrigerant tanks. Automobile repair shops use special refrigerant bottle openers to open the refrigerant tanks. The commonly used refrigerant bottle openers on the market are type 337, type 338 and type 339. They all have defects such as easy leakage at the ejector pin. In the international market, R134A refrigerant tanks are divided into puncture type and valve core type. For the self-sealing refrigerant tank of the valve core type, after the bottle opener is assembled, the ejector pin needs to be rotated to push open the valve core, resulting in low efficiency and inability to quickly perform subsequent operations. At the same time, the rotating ejector pin may also cause severe wear of the thread, resulting in leakage. Summary of the invention

The end faces of the upper ring frame and the lower ring frame are provided with a plurality of flow holes arranged along their circumferential directions, and the end faces of the upper ring frame and the lower ring frame are also provided with an axial hole for the shaft rod to pass through and install. The valve disc is arranged on the shaft rod and connected thereto, and the reset spring is sleeved on the shaft rod, and the two ends of the reset spring respectively contact with the valve disc and the upper ring frame, and the valve disc is sealed by contacting with the lower ring frame through the reset spring.

[0006] In the above-mentioned refrigerant bottle opener, the conduction unit is composed of a conduction plate and a conduction rod. The conduction plate is arranged in the adapter shell and slidably cooperates with it. The conduction rod is arranged on the conduction plate and connected with it, and the conduction plate is in conflict with the above-mentioned shaft rod through the conduction rod. The conduction plate is provided with a plurality of filling holes arranged along its circumferential direction and convenient for filling.

[0007] In the above-mentioned refrigerant bottle opener, a limiting ring connected to the inner wall of the adapter shell is provided for limiting the position of the conduction plate.

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1As shown, the refrigerant bottle opener comprises a bottle opener body 2 having a guide outlet 1 and a transfer shell 3 connected to the bottle opener body 2 and also connected to the refrigerant tank, and the transfer shell 3 is hollow, and a non-return unit connected to the transfer shell 3 and having a non-return seal is arranged inside the transfer shell 3, and a conduction unit connected to the transfer shell 3 and matched with the non-return unit is also arranged inside the transfer shell 3, and the non-return unit connects the refrigerant tank with the guide outlet 1, and the non-return unit is composed of an upper ring frame 4, a lower ring frame 5, and a shaft 6. The bottle opener body 2 is composed of a valve flap 7 and a reset spring 8. The upper ring frame 4 is arranged in the bottle opener body 2 and connected thereto. The lower ring frame 5 is arranged in the adapter shell 3 and connected thereto. The lower ring frame 5 is located at the upper end of the adapter shell 3. The end faces of the upper ring frame 4 and the lower ring frame 5 are provided with a plurality of flow holes arranged along the circumferential direction thereof. The end faces of the upper ring frame 4 and the lower ring frame 5 are also provided with an axial hole for the shaft rod 6 to pass through and be installed and slide with the shaft rod 6. The valve flap 7 is arranged on the shaft rod 6 and is connected thereto. The return spring 8 is sleeved on the shaft 6, and the two ends of the return spring 8 are respectively in contact with the valve disc 7 and the upper ring frame 4, and the valve disc 7 is sealed against the lower ring frame 5 by the return spring 8. The conduction unit is composed of a conduction plate 9 and a conduction rod 10. The conduction plate 9 is arranged in the adapter shell 3 and slidably cooperates with it. The conduction rod 10 is arranged on the conduction plate 9 and connected with it, and the conduction plate 9 is in contact with the above-mentioned shaft 6 by the conduction rod 10. There are several injection holes arranged along its circumferential direction and convenient for injection. The injection holes and the flow holes are arranged correspondingly. When the adapter shell 3 is connected to the refrigerant tank, the adapter shell 3 is rotated to cause the guide rod to contact the valve core and push the valve core open. The above-mentioned conduction plate 9 pushes the shaft rod 6, so that a gap appears in the seal of the lower ring frame 5, so as to inject refrigerant. After the injection is completed, the above-mentioned check unit is reset and sealed by rotating the steering shell, and the conduction rod 10 leaves the valve core at the same time.
