[0038] like Figure 1-5 As shown, the present invention provides a rainproof link rod, comprising a link head 1 and an insulating rod 2 detachably arranged at the lower side of the link head 1, and further comprising:

[0039] The rainproof mechanism 3 comprises an upper rainproof cover assembly 31 disposed between the link head 1 and the insulating rod 2, and a combined umbrella skirt cover 32 rotatably disposed at the lower side of the upper rainproof cover assembly 31, for preventing rainwater on the link head 1 from extending to the insulating rod 2;

[0040] A mounting mechanism 4, which is arranged at the center of the rainproof mechanism 3 and is detachably assembled with the link head 1 and the end of the insulating rod 2;

[0041] The water diversion mechanism 5 is arranged in the inner cavity of the upper rain cover assembly 31 and is used for diverting the rainwater collected in the upper rain cover assembly 31 .

[0042] In a specific implementation, by using the mounting mechanism 4 to assemble between the link head 1 and the insulating rod 2, on the one hand, the distance between the link head 1 and the upper end of the insulating rod 2 can be increased and adjusted, which can have the effect of adjusting the overall length of the link rod; on the other hand, it can prevent rainwater sliding down the link head 1 from sliding onto the insulating rod 2. At the same time, under the action of the upper rain cover assembly 31 included in the rainproof mechanism 3, the rainwater sliding down the link head 1 can be collected in the chamber to prevent the rainwater from continuing to slide onto the insulating rod 2. Subsequently, during use, the collected rainwater is discharged through the water diversion mechanism 5, thereby reducing the weight effect of the rainwater collection on the overall link rod, thereby reducing the adverse effects of the use of the link rod.

[0043] In one embodiment, the upper rain cover assembly 31 is composed of a rain cover 311 and an umbrella skirt 312;

[0044] The lower end of the spiral inner channel 313 is arranged at the bottom of the umbrella skirt 312. With this design, the rain collecting cover 311 and the umbrella skirt 312 are combined by an integrated molding process, and the rain collecting cover 311 is in the shape of a funnel with an open top, which can effectively collect rainwater and prevent the rainwater sliding off the clasp 1 from directly sliding onto the insulating rod 2, and the shape of the umbrella skirt 312 can also improve the safety of use in rainy weather.

[0045] Preferably, a spiral inner channel 313 for draining water is provided in the column where the rain collecting cover 311 and the umbrella skirt 312 are connected. In this design, the spiral inner channel 313 opened in the column where the rain collecting cover 311 and the rain collecting cover 311 are connected can utilize gravity and centrifugal force to make water flow more smoothly, reduce water flow resistance, and thus improve drainage efficiency.

[0046] It should be noted that the rain collecting cover 311, the umbrella skirt 312 and the combined umbrella skirt cover 32 are all made of silicone rubber.

When the combined umbrella skirt cover 32 is driven by an external force to rotate, the rainwater on its outer surface will be centrifugally scattered to prevent the rainwater from being retained on the outer surface of the combined umbrella skirt cover 32;

[0048] Also, through the central shaft 42 coaxially installed vertically and slidably on the central rod 41, the side plate 44 welded on the upper side of the central shaft 42, and the spring 45 welded on the end face of the side plate 44, when an external force pushes the central shaft 42, the spring 45 will elastically stretch, driving the central shaft 42 to move upward, so that the fixing ring 43 welded on the top end of the central shaft 42 enters the groove opened inside the lower end of the link head 1, thereby completing the fixation of the link head 1 and the rainproof mechanism 3.

[0049] It should be noted that the coaxially installed center rod 41 and center axis 42 both adopt a retractable structure at both ends and have a length adjustment function, and the overall minimum length of the center rod 41 is longer than or equal to the overall length of the upper rain cover assembly 31 and the combined umbrella skirt cover 32.

[0050] In one embodiment, the bottom end of the link head 1 is provided with a first threaded groove 11, and the upper part of the first threaded groove 11 is provided with a fixing sleeve 6 used in conjunction with the fixing ring 43.

In this design, the second threaded groove 411 machined at the bottom end of the center rod 41, the threaded joint 21 welded at the top end of the insulating rod 2, and the specifications of the internal thread of the second threaded groove 411 and the external thread of the threaded joint 21 are the same, and the two are inserted and rotated to complete the docking of the insulating rod 2 and the mounting mechanism 4.

[0052] It should be noted that when the insulating rod 2 is rotated and engaged at the bottom end of the center rod 41, the upward movement direction will push the center shaft 42 supported by the spring 45 to move upward until the fixing ring 43 welded on the top of the center shaft 42 is engaged with the fixing sleeve 6 installed inside the first threaded groove 11 opened at the lower end of the link head 1, thereby realizing the convenient assembly of the link head 1, the insulating rod 2, and the installation mechanism 4.

[0053] In addition, a first threaded connection groove 11 provided at the lower end of the link head 1 and a threaded joint 21 provided at the top end of the insulating rod 2 can be directly threadedly engaged, thereby realizing convenient assembly of the link head 1 and the insulating rod 2.

In this design, the hollow tube 51 is evenly welded on the inner wall of the rain collecting cover 311, and both ends are provided with open ends, and the nozzle 521 is plugged into the open top of the hollow tube 51. Under external force pumping, the rainwater collected in the rain collecting cover 311 can be dispersedly transported to the outside through the multiple conduits 522 welded on the ring-shaped fixed tube 523 and the corresponding nozzles 521, thereby reducing the accumulation of rainwater that affects the use effect of the link stick.

In this design, by connecting the welded connecting pipe 524 at one side of the annular fixed pipe 523 and welding the sealed cylindrical shell 53 at the other end of the connecting pipe 524, when an external force is applied to drive the blade 54 horizontally installed inside the cylindrical shell 53 to rotate, the rainwater collected inside the rain collecting cover 311 can be transported into the inner cavity of the annular fixed pipe 523 through the connecting pipe 524 through the rotating blade 54, and then discharged through the guide tube 522 and the nozzle 521.

[0057] Preferably, the plunger 55 installed at the lower part of the blade 54 can form a sealed space inside the cylindrical shell 53 to ensure a good water guiding effect.
