[0028] refer to Figures 1 to 4 According to a preferred embodiment of the RV jack of this utility model, it should be noted that the structure of the RV jack is as follows: Figure 1As shown, the RV jack includes a telescopic assembly 10 and a rotating assembly 20, with the rotating assembly 20 rotatably mounted on top of the telescopic assembly 10. Specifically, those skilled in the art will understand that the telescopic assembly 10 includes a fixed rod 11 and a movable assembly 12, with the movable assembly 12 slidably mounted within the fixed rod 11. Specifically, the fixing rod 11 has a first cavity, both ends of which are connected to the outside. A cover plate 13 is welded to the top of the fixing rod 11 to seal the bottom of the first cavity. The movable component 12 includes a first connecting rod 121 and a second connecting rod 122. The first connecting rod 121 has a second cavity that extends through it. One end of the first connecting rod 121 is located in the first cavity, and the other end passes through the first cavity and is located at the bottom of the fixing rod 11. The second connecting rod 122 has a third cavity that extends through it. One end of the second connecting rod 122 is located in the second cavity and is spaced a predetermined distance from the top of the first connecting rod 121. The other end of the second connecting rod 122 passes through the third cavity and is spaced a predetermined distance from the bottom of the first connecting rod 121.

[0029] Specifically, the movable component 12 further includes an insert 123, through which the first connecting rod 121 and the second connecting rod 122 are fixed. Specifically, the outer wall of the first connecting rod 121 has a first connecting hole, and the outer wall of the second connecting rod 122 has a second connecting hole. The first connecting hole is near the bottom of the first connecting rod 121, and the second connecting hole is near the bottom of the second connecting rod 122, with the first connecting hole directly opposite the second connecting hole. One end of the insert 123 engages with both the first and second connecting holes, and both ends of the insert 123 are located on opposite sides of the first connecting rod 121.

[0030] Specifically, the structure of the aforementioned insert 123 is as follows: Figure 2 As shown, it includes an insertion end 1231, abutment end 1232, and gripping end 1233. The insertion end 1231 is connected to the abutment end 1232, and the end of the abutment end 1232 opposite to the insertion end 1231 is also connected to the gripping end 1233. That is, the insertion end 1231 is engaged with the first connecting hole and the second connecting hole, while the abutment end 1232 contacts the outer wall of the first connecting rod 121. The gripping end 1233 is configured to facilitate the user to hold the insertion part 123 and engage it with the first connecting rod 121 and the second connecting rod 122.

[0031] In addition, the insertion end 1231 also has a limiting hole, which is spaced at a predetermined distance from the abutting end 1232. After the insertion piece 123 is installed, the user can insert the external pin into the limiting hole to limit the position of the insertion piece 123.

[0032] like Figure 1 As shown, a support plate 124 is also fixed at the bottom of the second connecting rod 122. The support plate 124 is welded to the bottom of the second connecting rod 122. The support plate 124 is set to contact the ground. Specifically, the movable component 12 is set to be able to move downward a predetermined distance, so that the support plate 124 contacts the ground.

[0033] Furthermore, the movable component 12 also includes a slider 125 and a lead screw 126. One end of the lead screw 126 passes sequentially through the cover plate 13, the first cavity, and the second cavity, and is placed inside the third cavity. The other end is located externally and spaced a predetermined distance from the cover plate 13. It should also be noted that the slider 125 engages with the wall forming the second cavity and is close to the top of the first connecting rod 121. Simultaneously, the lead screw 126 is connected to the slider 125. That is, when the lead screw 126 rotates, the slider 125 moves up or down along the lead screw 126. Since the slider 125 is fixed to the first connecting rod 121, the first connecting rod 121 and the slider 125 move synchronously. Simultaneously, the second connecting rod 122 also moves synchronously with the first connecting rod 121. In other words, the rotation of the lead screw 126 controls the raising and lowering of the support plate 124.

[0034] It should be noted that the aforementioned rotating assembly 20 also cooperates with the top of the lead screw 126, meaning that a person can manually drive the lead screw 126 to rotate via the rotating assembly 20. Specifically, the structure of the rotating assembly 20 is as follows: Figure 4As shown, it includes a rotating handle 21 and a connecting member 22. The connecting member 22 engages with the end of the rotating handle 21 and the top of the lead screw 126, respectively. That is, when the user rotates the rotating handle 21, the connecting member 22 drives the lead screw 126 to rotate synchronously. Specifically, the connecting member 22 has a first connecting portion 221 and two second connecting portions 222. The two second connecting portions 222 are arranged opposite each other and spaced at a predetermined distance. The first connecting portion 221 is arc-shaped, and both ends of the first connecting portion 221 are connected to the tops of the two second connecting portions 222, respectively. That is, the first connecting portion 221 and the two second connecting portions 222 are integrally formed. In addition, the end of the rotating handle 21 passes through the inner side of the first connecting portion 221. The rotating assembly 20 also includes a bolt 23 and a nut 24. The end of the bolt 23 passes through the ends of the two second connecting portions 222 and the lead screw 126 in sequence and is threadedly connected to the nut 24. That is, the user rotates the nut 24 to deform the two second connecting parts 222 toward each other, thereby causing the first connecting part 221 to press against the end of the rotating handle 21, thereby limiting the position of the rotating handle 21.

[0035] It should be noted that the advantages of this utility model include the quick-connect structure of the first connecting rod 121 and the second connecting rod 122, which facilitates subsequent assembly and disassembly. Furthermore, the structural design of the insert 123 also facilitates subsequent assembly and disassembly. Specifically, our previous insert structure was as follows: Figure 5 As shown, when the support plate 124 is subjected to excessive pressure, the inner walls of the first connecting hole of the first connecting rod 121 and the second connecting hole of the second connecting rod 122 will deform, which will make it difficult to remove the existing insert. However, the gripping end 1233 of the insert 123 of this utility model can cooperate with an external twisting device. That is, by rotating the insert 123, the deformed first connecting hole or second connecting hole will no longer squeeze the insert 123, so that the user can remove the insert 123.

[0036] In summary, the RV jack described in the embodiments of this application is explained, which provides advantages such as convenient disassembly and assembly of the telescopic part, high practicality, and simple structure.

[0037] It is worth mentioning that, in this embodiment, the RV jack has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the RV jack provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.
