Technical Field

[0001] This utility model relates to the technical field of outdoor equipment parts and accessories, and in particular to a quick-connect coupling for outdoor ovens. Background Technology

[0002] Outdoor grills are considered outdoor equipment and are essential for popular camping and picnics. However, many outdoor barbecue locations are inaccessible by vehicle, requiring the grills to be carried manually. Since outdoor grills are heavy, direct transport is inconvenient. To address this, technicians installed wheels on the bottom of the grills and a pull rod at one end. However, directly fixing the pull rod to the grill would take up too much space. Therefore, the pull rod needs to be designed for detachable connection. For example, a connecting pipe is typically installed on the side of the grill, and the pull rod connects to this pipe via a connector. The current technical challenge is how to achieve a quick-connection between the pull rod and the connecting pipe. Summary of the Invention

[0003] The purpose of this utility model is to provide a quick-connect coupling for outdoor ovens. Through the design of the quick-connect coupling, the pull rod can be quickly connected to the connecting pipe of the outdoor oven, and the pull rod, quick-connect coupling and outdoor oven can also be quickly separated, thereby achieving the purpose of quick assembly and disassembly.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick-connect coupling for an outdoor oven, comprising a coupling body, a connecting ring, a plug post, and a fixing nut.

A limiting slot is provided on the end face of the plug post; the fixing nut is threadedly connected to the threaded portion of the coupling body. When the fixing nut is screwed along the threaded portion to abut against the limiting surface of the connecting ring, the fixing nut and the limiting surface of the connecting ring abut against each other to limit the rotation of the connecting ring.

[0005] Furthermore, the connecting ring has a connecting portion, the connecting portion having a slot for inserting the first end portion of the connector body, the connector body being pivotally connected to the connecting portion via a pin a, the first end of the connector body having a flat groove to provide rotational space for the connecting portion to rotate, and the limiting surface being provided on the bottom end face of the connecting portion.

[0006] Furthermore, the connecting ring includes a first clamping ring and a second clamping ring, which are hinged together by a pin b. The switch structure includes a rotary switch and a limiting end. The rotary switch is rotatably connected to the other end of the first clamping ring relative to the pin b via a rotating shaft. The limiting end is fixedly disposed at the other end of the first clamping ring relative to the pin b. The limiting end is provided with a clearance channel for the rotary switch to rotate. The connecting ring is locked by locking the rotary switch with the limiting end.

[0007] Furthermore, the limiting slot is a U-shaped groove with an opening at the lower end, and the U-shaped groove passes through the periphery of the insertion post.

[0008] Furthermore, two fixing nuts are provided on the threaded portion of the connector body.

[0009] In summary, this utility model has the following beneficial effects:

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figures 1-5 As shown, a quick-connect coupling for an outdoor grill includes a coupling body 10, a connecting ring 20, a plug post 30, and a fixing nut 40. The coupling body 10 has a threaded portion 11 on its outer periphery. The connecting ring 20 is pivotally connected to the first end of the coupling body 10. The connecting ring 20 has a switch structure 21 for locking or unlocking the connecting ring 20. The connecting ring 20 has a connection port 22 for connecting to the outdoor grill. A limiting surface 231 is provided on the side of the connecting ring 20 adjacent to the coupling body 10. The plug post 30 is fixedly disposed at the second end of the coupling body 10. An annular positioning groove 31 is provided on the outer periphery of the plug post 30. A limiting slot 32 is provided on the end face of the plug post 30. The fixing nut 40 is threadedly connected to the threaded portion 11 of the coupling body 10. When the fixing nut 40 is screwed along the threaded portion 11 to abut against the limiting surface 231 of the connecting ring 20, the fixing nut 40 and the limiting surface 231 of the connecting ring 20 abut against each other to limit the rotation of the connecting ring 20.

[0019] In some embodiments, the connecting ring 20 has a connecting portion 23, which has a slot 232 for inserting the first end portion of the connector body 10. The connector body 10 is pivotally connected to the connecting portion 23 via a pin a233. The first end of the connector body 10 has a flat groove 234 to provide rotational space for the connecting portion 23. The limiting surface 231 is provided on the bottom end face of the connecting portion 23. Specifically, the connecting portion 23 has a U-shaped structure. Both sides of the first end of the connector body 10 have flat grooves 234 so that the width of the first end of the connector body 10 matches the width of the slot 232, thereby ensuring that the connecting portion 23 and the connecting ring 20 can rotate about the pin a233 as the axis of rotation.

[0020] In some embodiments, the connecting ring 20 includes a first clamping ring 24 and a second clamping ring 25, which are hinged together by a pin b26. The switch structure 21 includes a rotary switch 211 and a limiting end 212. The rotary switch 211 is rotatably connected to the other end of the first clamping ring 24 relative to the pin b26 via a rotating shaft 213. The limiting end 212 is fixedly disposed at the other end of the first clamping ring 24 relative to the pin b26. The limiting end 212 is provided with a clearance channel 2121 for the rotary switch 211 to rotate. The rotary switch 211 is locked to the limiting end 212. In conjunction with the locking connecting ring 20, specifically, the rotary switch 211 includes a rocker arm 2111 fixedly connected to the rotating shaft and a knob part 2112 threadedly connected to the rocker arm 2111. The rocker arm 2111 has a threaded section, and the knob part 2112 is threadedly connected to the threaded section. When the knob part 2112 is turned to abut against the limiting end 212, the connecting ring 20 is locked. In order to increase the locking effect, a washer 214 is provided at the lower end of the knob part 2112 and is provided on the rocker arm 2111. When the knob part 2112 is turned to press the washer 214 tightly against the limiting end 212, the connecting ring 20 can be locked.

[0021] The pull rod 50, used for connecting the quick connector, has a connecting structure 51 at one end. The connecting structure 51 includes a sleeve 52, a limiting steel ball 53, a limiting pin 54, and an elastic element 55. The sleeve 52 is slidably disposed on the pull rod 50 along its length. The limiting pin 54 is fixedly inserted into the sleeve 52 along a direction perpendicular to the length of the pull rod 50. The end of the pull rod 50 has a receiving cavity and a strip groove 58 for the limiting pin 54 to slide. The elastic element 55 is disposed between the limiting pin 54 and the inner end face of the receiving cavity. The end of the pull rod 50 has a limiting part 59 to prevent the sleeve 52 from disengaging from the pull rod 50. The outer periphery of the pull rod 50 has an annular groove 56 and several positioning holes 57. Multiple limiting steel balls 53 are provided, each corresponding to one of the positioning holes 57. The limiting steel balls 53 can partially extend into the receiving groove through the positioning holes 57. The central through hole of the sleeve 52 includes a... The sleeve 52 has a first hole section 521 and a second hole section 522 with a smaller diameter than the first hole section 521. The first hole section 521 is located at the end away from the elastic member 55. The sleeve 52 has an upward sliding tendency under the action of the elastic member 55, so that the limiting steel ball 53 is located in the area of ​​the second hole section 522. At this time, the limiting steel ball 53 is pressed into the positioning hole 57 by the pressure of the inner wall of the second hole section 522 of the sleeve 52, so that the limiting steel ball 53 is pressed into the annular positioning groove 31, so that the pull rod 50 is positioned with the axis of the quick connector. When the sleeve 52 is slid downward, so that the limiting steel ball 53 is located in the area of ​​the first hole section 521, the limiting steel ball 53 can exit the positioning hole 57 and disengage from the annular positioning groove 31, so that the axis positioning of the pull rod 50 and the quick connector is released. The limiting part 59 is located at the end of the strip groove 58, so as to prevent the sleeve 52 from disengaging from the pull rod 50.

[0022] The quick-connect connector is circumferentially positioned by the insertion and engagement of the limiting pin 54 and the limiting slot 32, that is, the quick-connect connector and the pull rod 50 achieve anti-rotation engagement. In some embodiments, the limiting slot 32 is a U-shaped groove with an open bottom and the U-shaped groove passes through the periphery of the insertion post 30, so that the limiting pin 54 can be inserted into the limiting slot 32. In this utility model, the outer diameter of the limiting pin 54 is adapted to the width of the limiting slot 32.

[0023] In some embodiments, the threaded portion 11 of the connector body 10 is provided with two fixing nuts 40, wherein the upper fixing nut 40 is used to abut against the limiting surface 231 of the connecting ring 20 to limit the rotation of the connecting ring 20, and the lower fixing nut 40 is used to abut against the end face of the pull rod 50 to make the quick connector and the pull rod 50 more securely connected, effectively solving the problem of easy shaking after the pull rod 50 and the quick connector are connected.

[0024] When it is necessary to release the limiting position of the fixing nut 40 on the connecting ring 20, simply turn the fixing nut 40 a certain distance away from the connecting ring 20. Similarly, when it is necessary to release the limiting position of the fixing nut 40 on the pull rod 50, simply turn the fixing nut 40 a certain distance away from the pull rod 50.

[0025] In summary, this utility model has the following beneficial effects:

[0026] This utility model is a quick-connect coupling for outdoor grills. Through the design of the quick-connect coupling, the pull rod 50 can be quickly connected to the connecting pipe of the outdoor grill, and the pull rod 50 and quick-connect coupling can also be quickly separated from the outdoor grill, thereby achieving the purpose of quick assembly and disassembly. Specifically, the connecting ring 20 is used to connect the connecting pipe of the outdoor grill, and the plug post 30 is used to connect the pull rod 50.
