For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the teachings of the utility model concept. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0030] refer to Figures 1 to 4 According to a preferred embodiment of the RV jack connection structure, it should be noted that the structure of the RV jack connection structure is as follows: Figure 1 and Figure 2 As shown, it is mounted on the outer wall of the RV jack to define the position of the RV jack and to support it. Specifically, this application provides a disassembly and assembly structure to facilitate easy installation of the RV jack by the user.

[0031] Among them, such as Figure 1 The RV jack structure shown includes a housing 10, a support rod 20 placed inside the housing 10, and a drive assembly 30. Those skilled in the art will understand that one end of the support rod 20 is vertically and flexibly placed inside the housing 10. A rotating handle is mounted on the top of the housing 10, with one end engaging with the drive assembly 30 and the other end externally. The drive assembly 30 also engages with the support rod 20. Notably, the connection method of rotating the rotating handle and then using the drive assembly 30 to move the support rod 20 up and down is a conventional structure. Specifically, the drive assembly 30 can be implemented as a screw-slider transmission, where the screw engages with both the rotating handle and the slider. The slider is fixed to the support rod 20; when the rotating handle is rotated, the screw rotates synchronously, causing the slider to move up and down along the screw, while simultaneously operating synchronously with the slider fixed to the support rod 20.

[0032] This application is installed on the outer wall of the aforementioned housing 10. The RV jack connection structure includes a housing assembly, which includes a mating plate 40. The mating plate 40 has two opposing first connecting plates 41 and a second connecting plate 42. The two ends of the second connecting plate 42 respectively engage with the sides of the two first connecting plates 41 that are close to each other. The two first connecting plates 41 and the second connecting plate 42 are integrally formed. Specifically, each of the two first connecting plates 41 has a first insertion hole 4101, which penetrates the corresponding first connecting plate 41, and the two first insertion holes 4101 correspond one-to-one. It should also be noted that the housing 10 also has two opposing second insertion holes, meaning the user can fasten the mating plate 40 onto the outer wall of the housing 10, thus making the two first insertion holes 4101 correspond one-to-one with the two second insertion holes. Specifically, the RV jack connection structure also includes a pin, which can engage with both the first insertion hole 4101 and the second insertion hole, thereby defining the position of the mating plate 40.

[0033] It should also be noted that the aforementioned mating plate 40 has another embodiment, namely, one side of the mating plate 40 has an arc-shaped mating groove 401, the outer wall of the housing 10 can mate with the arc-shaped mating groove 401, and then the user welds along the outer wall of the mating plate 40 to define the position of the mating plate 40, and then inserts the pin, thereby improving the connection reliability of the mating plate 40.

[0034] Specifically, the RV jack connection structure also includes a connecting column 50, which is stepped. One end of the connecting column 50 is fixedly connected to the side of the mating plate 40 opposite to the housing 10, i.e., the end of the connecting column 50 is fixed to the second connecting plate 42, and the fixing method of the connecting column 50 can be implemented by welding. It is worth mentioning that the connecting column 50 can be implemented as a hollow structure to reduce the weight or manufacturing cost of the connecting column 50. That is, one side of the connecting column 50 has a cavity with an opening, and the end of the connecting column 50 with the opening is fixed to the mating plate 40. Then, the user welds along the mating edge of the connecting column 50 and the mating plate 40. At the same time, welding a partition in the cavity can improve the structural strength of the connecting column 50 and prevent the connecting column 50 from deforming due to excessive pressure. In addition, it should be noted that the side of the connecting column 50 opposite to the opening also has a connection port, i.e., the positioning pin of the external vehicle can be inserted into the connection port, thereby initially defining the position of the connecting column 50.

[0035] Furthermore, the outer wall of the connecting post 50 has two third insertion holes 501, which are arranged opposite to each other and spaced apart by a predetermined distance. Both third insertion holes 501 are also connected to the cavity.

[0036] It should be noted that the outer wall of the connecting column 50 also has two stops 51. Both stops 51 are located on one side of the connecting column 50, and are arranged opposite to each other, spaced a predetermined distance apart. Specifically, both stops 51 are inclined, such as... Figure 1 As shown, it is shaped like an inverted V, and one of the third insertion holes 501 is located between the two stops 51.

[0037] Furthermore, the RV jack connection structure also includes an insert 60. One end of the insert 60 can pass through the two third insertion holes 501 in sequence and is located at the end of the stop 51 away from the connecting post 50. The other end is also located externally. In addition, the insert 60 also has an annular blocking portion 61, which is close to the stop 51 and spaced at a predetermined distance from the stop 51. It is worth mentioning that the RV jack connection structure also includes a limiting member 70. The limiting member 70 is disposed between the two stops and is configured to be fastened onto the insert 60, located on the side of the annular blocking portion 61 near the third insertion hole 501, thereby limiting the position of the insert 60. Specifically, the limiting member 70 has two insertion portions 71, two limiting portions 72, and an arc-shaped connecting portion 73. The two limiting portions 72 are folded, and one end of each of the two insertion portions 71 is connected to one end of each of the two limiting portions 72, and the other end of each of them cooperates with the insertion member 60. The other end of each of the two limiting portions 72 is connected to both ends of the arc-shaped connecting portion 73. That is, the two insertion portions 71, the two limiting portions 72, and the arc-shaped connecting portion 73 are all integrally formed. Specifically, the gap between the two insertion portions 71 and the two stops 51 is squeezed by the side of the two stops 51 that are close to each other, so that the two insertion portions 71 fit together. At the same time, the sides of the two limiting portions 72 that are opposite to each other respectively contact the side of the two stops 51 that are close to each other. The side of the two limiting portions 72 that are close to each other contacts the outer wall of the insertion member 60. That is, at this time, the size of the distance between the two limiting portions 72 is smaller than the cross-sectional size of the annular blocking portion 61, thereby limiting the position of the insertion member 60. In addition, those skilled in the art should understand that the end of the insertion member 60 that is opposite to the limiting portion 70 is the large end, that is, the size of this part is larger than the size of the third insertion hole 501.

[0038] It should also be noted that the fixing post of the external vehicle is penetrated by the aforementioned insert 60, thereby improving the connection strength between this application and the external vehicle.

[0039] Specifically, the insertion part 71 has a concave structure, meaning each insertion part 71 has a first rod 711, a second rod 712, and a third rod 713. The two first rods 711 are vertically arranged and connected to the two limiting parts, respectively, with their other ends connected to one end of the second rod 712. The two second rods 712 are horizontally arranged and located below the connecting post. One end of each of the two third rods 713 is connected to the other end of the two second rods 712, and the other end of each third rod 713 penetrates the insertion member 60 at the end away from the arc-shaped connecting part. During disassembly, the user can pull the arc-shaped connecting part 73 to disengage the two limiting parts 72 from the arc-shaped blocking part 61.

[0040] In summary, the RV jack connection structure described in the embodiments of this application is explained, which provides advantages such as quick disassembly and assembly, simple structure, and high practicality.

[0041] It is worth mentioning that, in this embodiment, the RV jack connection structure is simple in design, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the RV jack connection structure 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.
