[0002] Outdoor barbecue grills are a type of outdoor equipment, 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, moving them directly is inconvenient. To address this issue, technicians installed wheels on the bottom of the grills and a lever at one end, allowing users to pull the grill to the desired location. However, currently, this lever only serves as a tool for moving the grill, its function is relatively limited, and therefore, improvements are needed to enhance its functionality. Summary of the Invention

[0003] The purpose of this utility model is to provide a multifunctional pull rod. Through the design of the pull rod, it can not only be used as a tool for moving outdoor ovens, but also as a ground pole to support required objects, thereby effectively increasing the functionality of the pull rod.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multi-functional pull rod, including a rod body and a handle, the handle being connected to the first end of the rod body, the second end of the rod body being provided with a first connecting structure, and the end of the handle being provided with a second connecting structure. The rod body can be selectively fitted with a ground insert or a connecting joint through the first connecting structure. When the rod body is connected to the connecting joint through the first connecting structure, the pull rod is connected to an outdoor oven through the connecting joint, and at this time the pull rod is used as a tool for carrying the outdoor oven. When the rod body is connected to the ground insert through the first connecting structure, the pull rod acts as a ground insert to support the required object.

[0005] Furthermore, the pole can also be optionally fitted with foot pads via the first connecting structure to enable the pole to be used as a trekking pole.

[0006] Furthermore, the first connecting structure includes a sleeve, a limiting steel ball, a limiting pin, and an elastic element. The sleeve is slidably disposed on the rod body along the length direction of the rod body. The limiting pin is inserted into the sleeve along the direction perpendicular to the length direction of the rod body. The end of the rod body relative to the handle has a receiving cavity and a clearance channel for the limiting pin to slide. The elastic element is disposed between the limiting pin and the inner end face of the receiving cavity. The rod body is provided with a limiting part to prevent the sleeve from detaching from the rod body. The outer periphery of the rod body is provided with an annular groove and several positioning holes. Multiple limiting steel balls are provided and correspond one-to-one with the positioning holes. The limiting steel balls can partially extend into the receiving groove through the positioning holes. The central through hole of the sleeve includes a first hole section and a second hole section with a diameter smaller than that of the first hole section. Under the action of the elastic element, the sleeve slides until the limiting steel ball is located in the second hole section area. At this time, the limiting steel ball is pressed into the positioning hole after being pressured by the inner wall of the sleeve. When the sleeve is slid to the first hole section area by overcoming the elastic force of the elastic element, the limiting steel ball can exit the positioning hole.

[0007] Furthermore, the insertion component and the connecting connector are provided with a plug that matches the first connecting structure. The outer diameter of the plug matches the receiving cavity. One end of the plug that extends into the receiving cavity is provided with an annular groove. The axial direction of the plug is limited by the limiting steel ball and the annular groove.

[0008] Furthermore, an anti-rotation groove is provided on the end face of the insertion component and the connecting joint that extends into the accommodating cavity. The anti-rotation groove and the limiting pin cooperate to prevent rotation and limit the insertion component and the connecting joint in the circumferential direction.

[0009] Furthermore, the second connection structure includes a clamping block, a knob, and a connecting shaft. The handle has a through-hole, the clamping block is disposed in the connecting hole, the connecting shaft is threaded to the handle, one end of the connecting shaft is connected to the clamping block, and the other end of the connecting shaft is connected to the knob.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figures 1-9 As shown, a multi-functional pull rod includes a rod body 10 and a handle 20. The handle 20 is connected to the first end of the rod body 10. Preferably, the handle 20 is perpendicular to the rod body 10. The second end of the rod body 10 is provided with a first connecting structure 11, and the end of the handle 20 is provided with a second connecting structure 21. The rod body 10 can be selectively fitted with a ground insert 30 or a connecting joint 40 through the first connecting structure 11. When the rod body 10 is connected to the connecting joint 40 through the first connecting structure 11, the pull rod is connected to an outdoor grill through the connecting joint 40. At this time, the pull rod is used as a tool for carrying the outdoor grill. The function of the handle 20 is to facilitate the user's grip on the pull rod. When the rod body 10 is connected to the ground insert 30 through the first connecting structure 11, the pull rod acts as a ground insert to support the required object. For example, the pull rod is used to support an umbrella, which can be a sun umbrella or a rain umbrella. The pull rod is connected to the umbrella handle through the second connecting structure 21 of the handle 20, thereby supporting the umbrella.

[0028] In some embodiments, the pole 10 may also be optionally fitted with foot pads via the first connecting structure 11 to enable the pole to be used as a trekking pole, thereby further enhancing the functionality of the pole.

[0029] In some embodiments, the first connecting structure 11 includes a sleeve 111, a limiting steel ball 112, a limiting pin 113, and an elastic element 114. The sleeve 111 is slidably disposed on the rod 10 along the length direction of the rod 10. The limiting pin 113 is inserted into the sleeve 111 along the length direction perpendicular to the rod 10. One end of the rod 10 relative to the handle 20 has a receiving cavity and a clearance channel 115 for the limiting pin 113 to slide. The elastic element 114 is disposed between the limiting pin 113 and the inner end face of the receiving cavity. The rod 10 is provided with a limiting part 116 to prevent the sleeve 111 from disengaging from the rod 10. The outer periphery of the rod 10 is provided with an annular groove 117 and a plurality of positioning holes 118. Multiple positioning steel balls 112 are provided and correspond one-to-one with positioning holes 118. The positioning steel balls 112 can partially extend into the receiving groove through the positioning holes 118. The central through hole of the sleeve 111 includes a first hole section 1111 and a second hole section 1112 with a diameter smaller than the first hole section 1111. Under the action of the elastic member 114, the sleeve 111 slides until the positioning steel balls 112 are located in the area of ​​the second hole section 1112. At this time, the positioning steel balls 112 are pressed into the positioning holes 118 after being pressured by the inner wall of the sleeve 111. When the sleeve 111 is slid to the area of ​​the first hole section 1111 after overcoming the elastic force of the elastic member 114, the positioning steel balls 112 can exit the positioning holes 118.

[0030] In some embodiments, the insertion member 30 and the connecting connector 40 are provided with a connector 50 that matches the first connecting structure 11. The outer diameter of the connector 50 matches the receiving cavity. One end of the connector 50 extending into the receiving cavity is provided with an annular groove 51. The connector 50 is axially limited by a limiting steel ball 112 engaging with the annular groove 51. Further, the end face of the insertion member 30 and the connecting connector 40 extending into the receiving cavity is provided with an anti-rotation groove 52. The anti-rotation groove 52 engages with the limiting pin 113 to prevent rotation and circumferentially limit the insertion member 30 and the connecting connector 40.

[0031] The outer periphery of the connector 50 is provided with an annular groove 51, and the end face of the connector 50 is provided with an anti-rotation groove 52. When the connector 50 is inserted into the receiving groove of the rod body 10 and the anti-rotation groove 52 is engaged with the limiting pin 113, the circumferential positioning of the connector 50 and the rod body 10 is achieved. The position of the sliding sleeve 111 is used to assemble and disassemble the connector 50 and the rod body 10, that is, to assemble and disassemble the rod body 10 and the grounding component 30 and the connecting connector 40. Specifically, the sleeve 111 is under the action of the elastic element 114. When the limiting steel ball 112 is slid to the second hole section 1112 area, the limiting steel ball 112 is pressed into the positioning hole 118 by the inner wall of the sleeve 111, so that the limiting steel ball 112 and the annular groove 51 are positioned and engaged to axially limit the connector 50 and the rod 10. When the sleeve 111 is slid to the first hole section 1111 area by overcoming the elastic force of the elastic element 114, the limiting steel ball 112 can be withdrawn from the positioning hole 118, thereby releasing the axial limitation on the connector 50 and the rod 10.

[0032] Specifically, the connecting connector 40 includes a connector body 41, a connecting ring 42, a plug connector 50, and a fixing nut 43. The connector body 41 has a threaded portion on its outer periphery. The connecting ring 42 is pivotally connected to the first end of the connector body 41. The connecting ring 42 has a switch structure 44 for locking or unlocking the connecting ring 42. The connecting ring 42 has a connection port for connecting an outdoor oven. A limiting surface is provided on the side of the connecting ring 42 adjacent to the connector body 41. The plug connector 50 is fixedly disposed at the second end of the connector body 41. The fixing nut 43 is threadedly connected to the threaded portion of the connector body 41. When the fixing nut 43 is screwed along the threaded portion to abut against the limiting surface of the connecting ring 42, the fixing nut 43 abuts against the limiting surface of the connecting ring 42 to limit the rotation of the connecting ring 42.

[0033] In some embodiments, the second connection structure 21 includes a clamping block 211, a knob 212, and a connecting shaft 213. The handle 20 has a through-hole, the clamping block 211 is disposed in the through-hole, and the connecting shaft 213 is threaded to the handle 20. One end of the connecting shaft 213 is connected to the clamping block 211, and the other end of the connecting shaft 213 is connected to the knob 212. When the knob 212 is turned clockwise, the connecting shaft 213 and the clamping block 211 can be driven to move closer to the center of the through-hole. Specifically, rotating the knob 212 can drive the connecting shaft 213 to rotate relative to the handle 20. This allows the clamping block 211 to extend and retract. To prevent the clamping block 211 from rotating, the handle 20 has a limiting groove corresponding to the position of the clamping block 211, which limits its movement. The clamping block 211 is connected to the end face of the connecting shaft 213 by connecting screws. When the knob 212 rotates in the forward direction, it drives the connecting shaft 213 closer to the center of the connecting hole. Under the action of the connecting shaft 213, the clamping block 211 moves towards the center of the connecting hole. At the same time, the clamping block 211 cannot rotate because it is limited by the limiting groove. Similarly, when the knob 212 rotates in the reverse direction, it drives the connecting shaft 213 away from the center of the connecting hole. In this utility model, the shape of the connecting hole is set to a polygonal structure to prevent the handle 20 from rotating relative to the required connecting part, such as the umbrella handle of an umbrella body.

[0034] In some embodiments, the rod 10 includes an upper rod 12, a lower rod 13, and a telescopic structure 14. The lower end of the upper rod 12 is fitted inside the lower rod 13. The telescopic structure 14 includes an adjusting sleeve 141 and an elastic sleeve 142. The lower rod 13 has a cavity with an open upper end. The elastic sleeve 142 is fitted into the opening of the cavity. The outer diameter of the elastic sleeve 142 is larger than the aperture of the cavity. The upper rod 12 passes through the channel of the elastic sleeve 142 and extends into the cavity. The bottom of the upper rod 12 is provided with a limiting member 121 to limit its sliding out of the cavity. The outer periphery of the upper end of the lower rod 13 is provided with a threaded portion. When the adjusting sleeve 141 is screwed to the threaded portion of the lower rod 13, the lower rod 13 will squeeze the elastic sleeve 142, so that the elastic sleeve 142 contracts inward and tightens the upper rod 12, thereby fixing the upper rod 12 and the lower rod 13.

[0035] In some embodiments, the elastic sleeve 142 includes a flange 1421 and an annular portion disposed at the lower end of the flange 1421. The outer diameter of the flange 1421 is larger than the outer diameter of the annular portion. The lower end face of the flange 1421 abuts against the lower rod 13. The annular portion is provided with a plurality of spaced-apart cut grooves 1423. The cut grooves 1423 extend to the bottom of the annular portion so that the annular portion is divided into a plurality of elastic pieces 1422. The plurality of elastic pieces 1422 can contract inward after being squeezed.

[0036] In summary, this utility model has the following beneficial effects:

[0037] 1. The multifunctional pull rod of this utility model, through its design, enables the pull rod to not only be used as a tool for moving outdoor ovens, but also as a ground stake to support required objects, thereby effectively increasing the functionality of the pull rod;
