By setting an adjustment component and a lifting component, the effect of adjusting the height can be achieved while supporting the extension platform. Its structure is simple and easy to operate. At the same time, by setting a first anti-wear ring and a second anti-wear ring, wear can be reduced.

[0028] Figures 1-4 Shown is a schematic diagram of the overall structure of an embodiment of the adjustable support rod of the motorhome of the present utility model. Please refer to Figures 1-4 In this embodiment, the main body part of the adjustable support rod of the motorhome includes: a support component 100, an adjustment component 200, and a lifting component 300.

[0029] Specifically, the support component 100 includes a support tube 101 provided, a lower fixed shell 103 inserted into the top of the support tube 101, and an upper fixed shell 105 abutted against the top of the lower fixed shell 103. A bottom plate is provided at the bottom of the support tube 101, and the bottom plate is circular. During use, the support tube 101 is used to support the lifting component 300, and the cooperation of the lower fixed shell 103 and the upper fixed shell 105 facilitates the fixation of the adjustment component 200.

[0030] Further, the lower fixed shell 103 is fixedly connected to the support tube 101 through a first connecting device 102, and the top of the lower fixed shell 103 is fixedly connected to the upper fixed shell 105 through a second screw 104. During use, the support tube 101, the lower fixed shell 103, and the upper fixed shell 105 are fixed by means of the first connecting device 102 and the second screw 104 for easy installation and complete shipment.

[0031] Specifically, the adjustment component 200 includes a first anti-wear ring 201 placed inside the lower fixed shell 103, a first bevel gear 202 placed at the top of the first anti-wear ring 201, a second bevel gear 203 meshed with the first bevel gear 202, and an adjustment rod 204 inserted into the second bevel gear 203. The bevel gears are metal gears, which can increase durability. The single static load-bearing of the product is 5000 pounds. During use, the adjustment rod 204 can be pinched and rotated. The rotating adjustment rod 204 will drive the second bevel gear 203 and the first bevel gear 202 to rotate in sequence, so that the first bevel gear 202 will push the lifting component 300 to move up or down. At the same time, the wear between the first bevel gear 202 and the lower fixed shell 103 can be reduced through the first anti-wear ring 201.

[0032] Further, a first groove 2031 and a second groove 2041 are respectively formed in the inner side of the second helical gear 203 and the bottom of the adjusting rod 204. A fixing block 205 is inserted into the first groove 2031 and the second groove 2041. Two third screws 206 are threadedly connected to the second helical gear 203. The two third screws 206 are respectively abutted against the fixing block 205 and the adjusting rod 204. During use, the fixing block 205 plays a limiting role, so that the rotation of the adjusting rod 204 can drive the second helical gear 203, and the two third screws 206 can fix the fixing block 205 and the adjusting rod 204 in the second helical gear 203.

[0033] Specifically, the lifting assembly 300 includes a screw rod 301 threadedly connected to the first helical gear 202 and passing through the lower fixing shell 103 and the upper fixing shell 105, a lifting plate 302 arranged at the top of the screw rod 301, and a second anti-wear ring 303 bonded to the bottom of the lifting plate 302. During use, the rotating first helical gear 202 will push the screw rod 301 and the lifting plate 302 to move up or down, so as to adjust the height of the extension table. The structure is simple and easy to operate in this process. The second anti-wear ring 303 can prevent the lifting plate 302 from being worn due to friction with the upper fixing shell 105, and the service life is prolonged.

[0034] Further, a blocking rod 304 for blocking is inserted into the bottom of the screw rod 301. A jack for inserting the blocking rod 304 is formed in the bottom of the screw rod 301. During use, the blocking rod 304 plays a blocking role to prevent the screw rod 301 from detaching from the support tube 101, the lower fixing shell 103 and the upper fixing shell 105.

[0035] It should be noted that the second anti-wear ring 303 is a nylon flat washer, and the first anti-wear ring 201 is a stainless steel flat washer.

[0036] Combined with Figures 1-4 In this embodiment, when the adjustable support rod of the RV is specifically used, the user can place the support tube 101 of the support assembly 100 on the ground, and press the lifting plate 302 of the lifting assembly 300 against the extension table. Then, pinch the adjusting rod 204 of the adjusting assembly 200 and rotate it. The rotating adjusting rod 204 will drive the second helical gear 203 and the first helical gear 202 to rotate in sequence. Since the first helical gear 202 is threadedly connected to the screw rod 301, the rotating first helical gear 202 will push the screw rod 301 and the lifting plate 302 to move up or down, so as to adjust the height of the extension table. The structure is simple and easy to operate in this process. During the adjustment process, the first anti-wear ring 201 can reduce the wear between the first helical gear 202 and the lower fixing shell 103, and the second anti-wear ring 303 can prevent the lifting plate 302 from being worn due to friction with the upper fixing shell 105, and the service life is prolonged.
