Detailed Implementation

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-6 In this embodiment of the invention, a sliding connection structure 1 includes a guide plate 11 and a sliding seat 12. The two sides of the guide plate 11 are turned upward to form side flanges 111. The outer edge of the side flanges 111 is provided with guide protrusions 112. The sliding seat 12 includes a mounting body 121. The mounting body 121 is movably disposed on the guide plate 11. Guide blocks 122 are detachably mounted on both sides of the mounting body 121. A guide groove 123 that cooperates with the guide protrusions 112 is opened on the side of the guide block 122 near the mounting body 121.

[0029] It should be noted that the guide plate 11 serves as the support component of the sliding seat 12. The side flange 111 and the surface of the guide protrusion 112 form a straight track. The sliding seat 12 achieves directional sliding through the cooperation of the guide groove 123 and the guide protrusion 112. The guide block 122 adopts a detachable design, which is convenient for installation and disassembly. After the guide block 122 is worn, it can be removed and replaced separately without replacing the entire sliding seat 12, thus saving resources.

[0030] A bolt groove 124 is provided on the side of the mounting body 121 near the guide plate 11. An inspection port 1224 communicating with the bolt groove is provided on the side of the mounting body perpendicular to the guide plate. A first through hole 125 communicating with the bolt groove 124 is provided on the side of the sliding seat 12. A first bolt 127 passes through the first through hole 125. A first threaded hole 126 is provided on the guide block 122. The first bolt 127 passes through the first through hole 125 and is screwed into the first threaded hole 126. 2. The first bolt 127 is detachably connected to the mounting body 121. After the guide block 122 is worn, the first bolt 127 can be unscrewed and the guide block 122 can be removed and replaced. The bolt groove 124 can be used to hide and protect the head of the first bolt 127, so as to avoid damage to the head of the first bolt 127 and the inability to tighten it. The inspection port 1224 can be used to insert tools into the bolt groove 124 through the inspection port 1224 to tighten the first bolt 127 when installing or removing the guide block 122.

[0031] An installation groove is provided on the side of the mounting body 121 near the guide plate 11. A roller 128 is rotatably installed in the installation groove. The roller 128 contacts the guide plate 11. During the sliding process of the sliding seat 12, the roller 128 plays the role of auxiliary support and positioning guidance, which improves the stability of the sliding seat 12 during the sliding process.

[0032] A rotating shaft 129 is mounted on the roller 128. The mounting groove includes a roller groove section 1210 and a rotating shaft groove section 1211. The roller 128 is disposed in the roller groove section 1210, and the rotating shaft 129 is disposed in the rotating shaft groove section 1211. A baffle 1212 is provided at the opening of the mounting groove. An opening 1213 is provided on the baffle 1212 at the corresponding position of the roller groove section 1210. The roller 128 protrudes from the opening 1213. By setting the baffle 1212, the roller 128 can be restricted within the mounting groove to prevent the roller 128 from falling out of the mounting groove during sliding.

[0033] The baffle 1212 has a second through hole 1214, and a second bolt 1215 passes through the second through hole 1214. The mounting body 121 has a second threaded hole 1216, and the second bolt 1215 passes through the second through hole 1214 and is screwed into the second threaded hole. The baffle 1212 is detachably connected to the mounting body 121 by the second bolt 1215, which facilitates the installation of the roller 128 and the baffle 1212.

[0034] In order to better confine the roller 128 within the mounting groove, the baffle 1212 is provided with a top block 1217 extending into the shaft groove 1211, and the top block 1217 abuts against the shaft 129.

[0035] The inner wall of the guide groove 123 is provided with a gasket 1218, and the outer surface of the gasket 1218 is provided with a positioning block 1219. The inner wall of the guide groove 123 is provided with a positioning groove 1220 that mates with the positioning block 1219. The positioning block 1219 is provided with a locking post 1221. The side of the guide block 122 is provided with a locking hole 1222 that communicates with the positioning groove 1220. The locking post 1221 is inserted into the locking hole 1222. By providing the gasket 1218, contact between the inner wall of the guide groove 123 and the guide protrusion 112 can be avoided, thus reducing the height of the guide block 122. The probability of wear is reduced, and the gasket 1218 is detachably fixed in the guide groove 123 through the cooperation of the locking post 1221, the locking hole 1222, the positioning block 1219 and the positioning groove 1220. After the gasket 1218 wears out, the gasket 1218 can be removed and replaced separately, further saving resources. The locking hole 1222 adopts a through-type structure design. When replacing the gasket 1218, a tool can be used to insert into the locking hole 1222 from the outside of the guide block 122 to push the gasket 1218 out of the guide groove 123, which is convenient for replacing the gasket 1218.

[0036] The guide groove 123 is concave arc shape, and the shape of the guide protrusion 112 is adapted to the shape of the guide groove 123. The gasket is arc-shaped, and the gasket 1218 wraps around the surface of the guide protrusion 123. The design of the arc-shaped guide groove 123 and the arc-shaped guide protrusion 112 to fit together makes the sliding seat 12 more stable during movement and avoids swaying.

[0037] The inner wall of the gasket 1218 has several grooves 1223 along its length, so that lubricating grease can be filled in the grooves 1223 to achieve good lubrication, reduce wear, and improve stability.

[0038] The installation process of this invention is as follows: First, the rotating shaft 129 is threaded onto the roller 128. Then, the roller 128 and the rotating shaft 129 are placed in the roller groove section 1210 and the rotating shaft groove section 1211, respectively. Then, the baffle 1212 is placed at the opening of the mounting groove. Next, the second bolt 1215 is passed through the second through hole 1214 and screwed into the second threaded hole 1216 to complete the installation of the roller 128. After the roller 128 is installed, the mounting body 121 is placed on the guide plate 11. Then, the gasket 1218 is installed into the guide groove 123. Next, the guide block 122 is placed on the side of the mounting body 121 so that the guide protrusion 112 extends into the guide groove 123 and contacts the gasket 1218. Then, the first bolt 127 is passed through the first through hole 125 and screwed into the first threaded hole 126 to complete the installation of the sliding connection structure 1.

[0039] Please see Figure 7 The present invention also provides a lifting support, which includes two sets of sliding connection structures 1 as described above. The two sets of sliding connection structures 1 are arranged vertically at intervals. An X-shaped scissor-type lifting support 2 is provided between the two sets of connection structures. The X-shaped scissor-type lifting support 2 includes a first inclined rod 21 and a second inclined rod 22. The first inclined rod 21 and the second inclined rod 22 are arranged in an X-shape. One end of the first inclined rod 21 is hinged to the guide plate 11 of the upper sliding connection structure 1, and the other end of the first inclined rod 21 is hinged to the sliding seat 12 of the lower sliding connection structure 1. One end of the second inclined rod 22 is hinged to the guide plate 11 of the lower sliding connection structure 1, and the other end of the second inclined rod 22 is hinged to the sliding seat 12 of the upper sliding connection structure 1.

[0040] The following is a method for applying a lifting bracket: Two sets of lifting brackets are set on both sides of the roof of the vehicle. The lower sliding connection structure 1 of the lifting bracket is installed on the roof of the vehicle, and the upper sliding connection structure 1 is connected to the flat roof of the RV to be lifted. By adding a power device or manually adjusting the folding state of the first inclined rod 21 and the second inclined rod 22, the flat roof of the RV is driven to rise and fall.
