Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0019] like Figures 1 to 8 As shown, the anti-loosening beer keg connector mainly includes a connector 1, a rotating rod 8, a rod body 10, a notch 11, a probe 12, a locking mechanism 2, a liquid outlet pipe 4, a second connection port 5, an air inlet pipe 7, and a first connection port 6. The specific structure and connection relationship of each component are as follows.

[0020] Connector 1 is the main component of the connector. Probe 12 is a cylindrical structure with a pointed tip at one end for piercing a beer barrel, and the other end is slidably connected to connector 1. Specifically, the outer wall of probe 12 has a guide groove, and the inner wall of connector 1 has a corresponding guide protrusion, thereby enabling axial sliding of probe 12 relative to connector 1 while restricting its radial rotation. Notch 11 is an annular or arc-shaped notch machined in the middle of probe 12 for movable connection with subsequent components.

[0021] One end of the rotating rod 8 is rotatably connected to the connector 1. Specifically, one end of the rotating rod 8 is fixedly connected to the outer wall of the connector 1 via a hinge or a pivot, and can rotate around the pivot at a certain angle. The rod body 10 is a slender rod-shaped structure, with one end fixedly connected to the free end of the rotating rod 8 for movable connection with the notch 11. When the rotating rod 8 rotates, the rod body 10 swings accordingly, thereby driving the probe 12 to move axially downward through the notch 11, thus realizing the piercing operation of the beer barrel.

[0022] A locking mechanism 2 is installed at the connection between the connector 1 and the probe 12 to lock the position of the probe 12 and prevent it from springing back and loosening due to vibration or pressure during use. This locking mechanism 2 ensures the stability of the connector and improves safety during use.

[0023] In addition, the connector also includes components for fluid transfer: the outlet pipe 4 is a flexible pipe, one end of which is sealed to the side wall of the probe 12 and communicates with the inside of the beer barrel through a channel within the probe 12 for extracting beer; the second connection port 5 is a threaded interface or quick connector, located at the free end of the outlet pipe 4, for connecting to an external beer delivery pipeline. The air inlet pipe 7 is another flexible pipe, located at the upper part of the connector 1, and communicates with the inside of the beer barrel through a channel within the connector 1 for introducing gas to drive the beer flow; the first connection port 6 is a threaded interface-like interface, located at the free end of the air inlet pipe 7, for connecting to an external gas source, i.e., a CO2 cylinder.

[0024] In practical use, first, align the connector with the valve opening of the beer keg, and pull down the lever 8 to drive the probe 12 through the connector 1 until the probe 12 is fully inserted into the beer keg valve. At this point, the locking mechanism 2 automatically triggers, locking the probe 12 in place to prevent loosening. Next, connect the gas source through the first connector 6 to input pressurized gas into the air inlet pipe 7, and simultaneously connect the beer delivery line through the second connector 5 to extract beer from the outlet pipe 4. This design ensures smooth connection and anti-loosening function. When disassembly is required, release the locking mechanism 2 and rotate the lever 8 in the opposite direction to safely remove the probe 12.

[0025] This embodiment provides a locking mechanism 2 for an anti-loosening beer keg connector, further optimizing the locking function of the connector and ensuring that the probe 12 can be stably locked after piercing the beer keg, preventing loosening or detachment due to vibration or pressure. The specific structure of the locking mechanism 2 includes a sliding sleeve 208, a crossbeam 204, a bracket 205, a sliding rod 206, a spring 207, a connector 203, a protrusion 201, a connecting plate 209, and a connector groove 202. The sliding sleeve 208 is fitted onto the rotating rod 8 and slidably connected to it. The outer wall of the rotating rod 8 is machined with a guide groove, and the inner wall of the sliding sleeve 208 is provided with a corresponding guide protrusion, allowing the sliding sleeve 208 to slide along the length of the rotating rod 8 while restricting its radial rotation. One end of the crossbeam 204 is fixedly connected to the sliding sleeve 208, and the other end is slidably connected to the sliding rod 206. The slide rod 206 is a slender cylindrical structure, arranged along the sliding direction of the crossbeam 204, with one end fixedly connected to the bracket 205 by welding or bolts. The bracket 205 is an L-shaped or U-shaped frame, fixedly connected to the rotating rod 8, serving to support the slide rod 206. The spring 207 is a compression spring, sleeved on the slide rod 206, with its two ends abutting against the crossbeam 204 and the bracket 205 respectively. The spring 207 maintains a certain preload in its natural state. When the crossbeam 204 slides along the slide rod 206, the spring 207 is compressed, deformed, and stores elastic potential energy. The connecting plate 209 is a flat plate structure, fixedly connected to the sliding sleeve 208, used to enhance the connection stability between the sliding sleeve 208 and the crossbeam 204. The plug-in 203 is a columnar or hook-shaped structure, fixedly connected to the crossbeam 204. The protrusion 201 is a rectangular or trapezoidal protrusion, fixedly installed on the inner or outer wall of the joint 1. The insertion slot 202 is a groove that matches the shape of the insertion piece 203 and is machined on the protrusion 201 to accommodate the insertion piece 203 for locking. The upper surface of the protrusion 201 is designed as an arc-shaped guide surface. When the insertion piece 203 slides along the arc-shaped guide surface, the spring 207 is gradually compressed to store elastic potential energy until the insertion piece 203 slides into the insertion slot 202 to complete the locking.

[0026] In actual use, the operator pulls the rotating rod 8, causing the rotating rod 8 to drive the sliding sleeve 208 to slide along its length. The sliding sleeve 208 drives the connector 203 towards the protrusion 201 via the crossbeam 204. As the connector 203 contacts the arc-shaped guide surface of the protrusion 201, the crossbeam 204 slides along the sliding rod 206, compressing the spring 207 and storing elastic potential energy. When the connector 203 slides completely into the connector slot 202, the elastic potential energy of the spring 207 is partially released, pushing the connector 203 to tightly engage in the connector slot 202, thereby locking the position of the probe 12. At this time, the probe 12 is fully inserted into the beer barrel valve, and the locking mechanism 2 ensures that it will not loosen due to external vibration or internal pressure. To unlock, the operator causes the sliding sleeve 208 to drive the crossbeam 204 and the connector 203 out of the connector slot 202, and then rotates the rotating rod 8, allowing the probe 12 to be safely pulled out.

[0027] The locking mechanism 2 in this embodiment achieves a highly efficient and reliable locking function through the coordinated action of the sliding sleeve 208, the spring 207, and the connector 203, combined with the protrusion 201 and the connector groove 202. It has a compact structure and is easy to operate.

[0028] This embodiment further provides an anti-loosening beer keg connector, adding a handle 9 and a trigger mechanism 3 to optimize operational convenience and the unlocking function of the locking mechanism. Based on the original connector, this embodiment enhances the maneuverability of the rotating rod 8 through the handle 9 and achieves precise control of the locking mechanism 2 through the trigger mechanism 3, ensuring that the probe 12 can be securely locked after piercing the beer keg and easily unlocked. The structure, connection relationship, and working principle of the handle 9 and the trigger mechanism 3 are described in detail below.

[0029] The armrest 9 is an ergonomically designed grip component, fixedly connected to the free end of the rotating rod 8. The armrest 9 can be cylindrical or have an arc-shaped structure that conforms to the hand grip. The armrest 9 is fixedly connected to the rotating rod 8 in a one-piece molding manner, allowing the operator to more easily pull or rotate the rotating rod 8, thereby driving the probe 12 to pierce the beer barrel or triggering subsequent unlocking actions.

[0030] The triggering mechanism 3 assists in the unlocking operation of the locking mechanism 2, ensuring that the connector 203 can smoothly exit from the connector slot 202, thereby releasing the locked state of the probe 12. The triggering mechanism 3 includes a first contact plate 301, a second contact plate 302, a connecting plate 303, a limiting rod 304, a base plate 305, and a pressing part 306. The structure and connection relationship of each component are as follows: The first contact plate 301 is a trapezoidal plate structure, fixedly connected to the connecting plate 209 of the locking mechanism 2. Its inclined surface faces the second contact plate 302, for contacting the inclined surface of the second contact plate 302. The second contact plate 302 is also a trapezoidal plate structure, with its inclined surface opposite to the inclined surface of the first contact plate 301, and can slide against the inclined surface of the first contact plate 301. The second contact plate 302 is fixedly connected to the connecting plate 303 by bolts or integral molding. The connecting plate 303 is a rectangular or elongated structure used to connect the second contact plate 302 and the limiting rod 304. The connecting plate 303 and the limiting rod 304 are slidably connected. Specifically, the connecting plate 303 has a through hole through which the limiting rod 304 passes, allowing the connecting plate 303 to slide along the axial direction of the limiting rod 304. The limiting rod 304 is a slender cylindrical structure, with one end fixedly connected to the base plate 305. The function of the limiting rod 304 is to guide the sliding direction of the connecting plate 303 and limit its offset. The base plate 305 is a flat plate structure, fixedly connected to the rotating rod 8, preferably by bolts or welding, used to support the limiting rod 304 and provide a stable mounting base for the trigger mechanism 3. The pressing part 306 is an integrally formed protruding structure located on the upper surface of the connecting plate 303, above the armrest 9. The pressing part 306 can be a circular or rectangular button, and its surface can be textured with anti-slip material for easy pressing with the operator's fingers. The distance between the pressing part 306 and the armrest 9 is moderate, allowing the operator to conveniently press it with their thumb or other fingers while holding the armrest 9.

[0031] In actual use, the operator holds the handle 9 and pulls the rotating rod 8, causing the rotating rod 8 to slide the sliding sleeve 208 of the locking mechanism 2, thereby driving the connector 203 to engage with the insertion groove 202 on the protrusion 201, completing the locking operation of the probe 12. When unlocking is required, the operator presses the pressing part 306 with their finger to apply downward pressure, causing the connecting plate 303 to slide along the limiting rod 304 towards the base plate 305. At this time, the inclined surface of the second contact plate 302 slides into contact with the inclined surface of the first contact plate 301. Due to the trapezoidal inclined surface design of both, the second contact plate 302 pushes the first contact plate 301 to move laterally, thereby driving the connector 203 to move away from the insertion groove 202 through the connecting plate 209 and the sliding sleeve 208, ultimately causing the connector 203 to disengage from the insertion groove 202 and releasing the locked state of the probe 12. After unlocking, the operator can pull the rotating rod 8 in the opposite direction through the handle 9 to safely remove the probe 12.

[0032] This embodiment significantly improves the ease of operation and unlocking efficiency of the beer keg connector by adding a handle 9 and a trigger mechanism 3. The handle 9 optimizes the operation experience of the lever 8, and the design of the pressing part 306 and the trapezoidal contact plate makes the unlocking operation more intuitive and effortless. The sliding connection structure of the trigger mechanism 3 ensures the smoothness and reliability of the operation, and all components are made of corrosion-resistant materials, meeting food safety and mechanical durability requirements.

[0033] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
