[0001] This utility model relates to the field of gas cylinder valve connector technology, specifically a quick connector for gas cylinder valves. Background Technology

[0002] Cylinder valves are an important component of the gas cylinder system. They are installed at the cylinder opening and their main functions include sealing the cylinder, regulating the gas flow rate, and emergency shut-off. Therefore, cylinder valves directly determine the safety and controllability of the gas cylinder. Quick couplings for cylinder valves are structures that connect cylinder valves and pipelines and are auxiliary components in the gas cylinder system.

[0003] However, existing quick-connect couplings for gas cylinder valves have the following problems when used: Since leaks in the joints can cause not only economic losses but also potential dangers, the device needs to trigger an alarm to ensure that users can handle leaks promptly. However, existing quick-connect fittings for gas cylinder valves do not easily trigger an alarm when a leak occurs, which reduces the safety of the device.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing quick-connect couplings for gas cylinder valves. Summary of the Invention

[0005] The purpose of this invention is to provide a quick connector for gas cylinder valves to solve the problem mentioned in the background art that existing quick connectors for gas cylinder valves are not easy to trigger an alarm when there is a leak, thus reducing the safety of the device.

A protective cover is fixedly provided on the outer wall of the connector body, and a limit sleeve is fixedly connected to the upper surface of the protective cover. A knob is threaded on the inner wall of the limit sleeve. A triggering mechanism is provided on the upper inner wall of the protective cover, and a switch is installed on the inner wall of the protective cover on the side of the triggering mechanism.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a quick connector for a gas cylinder valve, comprising a gas cylinder valve body 1, a connector body 2, an air pipe 3, a limiting ring 4, an inner sealing ring 5, a base 6, an outer sealing ring 7, a protective cover 8, a limiting sleeve 9, a knob 10, a triggering mechanism 11, a support plate 1101, a push rod 1102, a spring 1103, a switch 12, an alarm 13, and a sealing ring 14. The connector body 2 is sleeved on the outer side of the gas cylinder valve body 1, and the air pipe 3 is fixedly connected to the inner wall of the end of the connector body 2. A limiting ring 4 is fixedly provided on the inner wall of the connector body 2 on the side of the air pipe 3. Furthermore, an inner sealing ring 5 is bonded to the outer wall of the side of the limiting ring 4, a base 6 is fixedly connected to the outer wall of the gas cylinder valve body 1 on the side of the connector body 2, an outer sealing ring 7 is fixedly installed on the outer wall of the base 6 on the side of the connector body 2, a protective cover 8 is fixedly installed on the outer wall of the connector body 2, a limiting sleeve 9 is fixedly connected to the upper surface of the protective cover 8, a knob 10 is threaded on the inner wall of the limiting sleeve 9, a triggering mechanism 11 is provided on the upper inner wall of the protective cover 8, a switch 12 is installed on the inner wall of the protective cover 8 on the side of the triggering mechanism 11, and an alarm 13 is provided on the outer wall of the protective cover 8 on the side of the switch 12.

[0017] The connector body 2 and the gas cylinder valve body 1 are threaded together, and the connector body 2 and the outer sealing ring 7 are fitted together. The gas cylinder valve body 1 and the inner sealing ring 5 are fitted together, so that after the user rotates and installs the connector body 2, the connector body 2 is tightly fitted to the outer sealing ring 7. At the same time, the connector body 2 drives the limiting ring 4 to make the inner sealing ring 5 tightly fitted to the gas cylinder valve body 1, thereby improving the sealing performance of the connector through double sealing.

[0018] Both the protective cover 8 and the knob 10 are threaded onto the base 6. A sealing ring 14 is bonded to the surface of the base 6 on the side of the protective cover 8, and the sealing ring 14 and the protective cover 8 are fitted together. This allows the protective cover 8 to be rotated and installed onto the base 6 and to be tightly fitted with the sealing ring 14 when the connector body 2 is rotated and installed, thereby ensuring the sealing performance of the protective cover 8. It also allows the user to rotate the knob 10 so that the knob 10 moves relative to the limiting sleeve 9 and is inserted into the base 6, thereby limiting the protective cover 8 and the connector body 2 and preventing the connector body 2 from becoming loose.

[0019] The triggering mechanism 11 includes a support plate 1101, a push rod 1102 and a spring 1103. The support plate 1101 is fixedly installed on the inner wall of the protective cover 8, and the push rod 1102 is movably installed on the inner wall of the support plate 1101, so that gas can push the triggering mechanism 11, causing the triggering mechanism 11 to trigger the switch 12, thereby turning on the alarm 13 to sound an alarm.

[0020] The push rod 1102 forms a sliding structure with the support plate 1101 and the protective cover 8 respectively. The outer wall of the push rod 1102 is connected to the surface of the support plate 1101 through the spring 1103. The cross-sectional shape of the push rod 1102 is set to an "L" shape, so that when the gas in the protective cover 8 increases, the gas pressure in the protective cover 8 will increase. At this time, the gas pushes the push rod 1102 to move relative to the support plate 1101 and compresses the spring 1103, thereby causing the push rod 1102 to trigger the switch 12 to turn on the alarm 13 to sound an alarm.

[0021] The top rod 1102 and the switch 12 are in contact, and the switch 12 and the alarm 13 are electrically connected, so that the top rod 1102 can move to trigger the switch 12, and the switch 12 can control the alarm 13.

[0022] Working principle: When using the quick connector for this gas cylinder valve, first as follows... Figure 1-4 As shown, the user places the connector body 2 onto the gas cylinder valve body 1 and tightens it. At this time, the connector body 2 is tightly against the outer sealing ring 7, and the connector body 2 drives the limiting ring 4 to make the inner sealing ring 5 tightly against the gas cylinder valve body 1. Simultaneously, as the connector body 2 is tightened, the connector body 2 drives the protective cover 8 to tighten. At this time, the protective cover 8 is tightly against the sealing ring 14. Next, the user rotates the knob 10, and then the knob 10 moves relative to the limiting sleeve 9 and inserts into the base 6, thereby limiting the protective cover 8 and the connector body 2 to prevent the connector body 2 from loosening. At this time, the connector body 2 is installed and connects the gas cylinder valve body 1 and the gas pipe 3, and at the same time, it is connected by the inner sealing ring 5 and the outer sealing ring 7. Ring 7 improves the sealing of the joint. When a leak occurs at the joint, the leaked gas leaks into the protective cover 8 through the gap between the gas cylinder valve body 1 and the joint body 2. As the gas in the protective cover 8 increases, the gas pressure in the protective cover 8 increases. At this time, the gas pushes the push rod 1102 to move relative to the support plate 1101 and compresses the spring 1103. Then the push rod 1102 triggers the switch 12, thereby turning on the alarm 13 (the alarm in this technical solution is an existing product sold on the market, specifically model KS-12D05YA buzzer alarm) to sound an alarm. Therefore, the device can easily alarm in time when there is a leak, thereby improving the safety of the device.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
