Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an extended luggage rack for automobiles. Example

[0026] Combination Figure 1-4 As shown, this utility model provides an extended luggage rack for automobiles, comprising: a base frame 100 and an adjustment assembly 200; the base frame 100 includes fixed seats 101 fixedly installed at its four bottom corners, pressure plates 102 movably installed at the outer ends of the fixed seats 101, and hexagon socket head cap screws 103 threadedly connected between the pressure plates 102 and the fixed seats 101; the adjustment assembly 200 includes a front extension plate 201 and a rear extension plate 202 movably installed at the front and rear ends of the base frame 100 respectively, first support bars 203 fixedly installed on both sides of the front extension plate 201 and the rear extension plate 202, second support bars 204 fixedly installed in the middle of the front extension plate 201 and the rear extension plate 202, third support bars 205 fixedly installed on both sides of the front extension plate 201 and the rear extension plate 202, and first support grooves 206 penetrating through both sides of the base frame 100. Multiple sets of fixing rods 207 are arranged and fixedly installed in the middle of the base frame 100. Fixing blocks 208 are arranged and fixedly installed on the upper sides of both sides of the base frame 100. Each fixing rod 207 has a second support groove 209, and the second support bars 204 are movably installed in the second support groove 209. Each fixing block 208 has a third support groove 210, and the third support bars 205 are movably installed in the third support groove 210. Each first support bar 203 also has a set of insertion holes 211. Each of the four corners of the base frame 100 has a threaded hole 212. Each threaded hole 212 and insertion hole 211 has an adjusting screw 213 movably installed in the threaded hole 212 and the insertion hole 211. Each fixing block 208 also has a binding opening 214. Each of the front extension plate 201 and the rear extension plate 202 has a set of slots 215. Each first support bar 203 is movably installed in the first support groove 206.

[0027] Specifically, a car roof rack is an accessory installed on the roof of a car, with the core function of expanding storage space. The front extension plates 201 and rear extension plates 202 of this rack 100 can be easily extended and adjusted at the front and rear, thereby increasing the overall area of ​​the rack 100 and improving its loading capacity. After adjustment, the front extension plates 201 and rear extension plates 202 are supported and connected to the rack 100 through multiple sets of first support bars 203, third support bars 205, and second support bars 204 on both sides and in the middle, thus providing a more even and stable support for the adjusted front extension plates 201 and rear extension plates 202. The extension plate 202 provides support to ensure the stability of the front extension plate 201 and rear extension plate 202 after adjustment, thereby preventing wobbling during use due to poor stability after adjustment. Furthermore, the front extension plate 201 and rear extension plate 202 at both ends of the base frame 100 can be easily disassembled and assembled according to usage requirements, thus improving its flexibility in use. The first support bars 203 at both ends of the front extension plate 201 and rear extension plate 202 are movably fitted into the first support grooves 206 on both sides of the base frame 100. The first support grooves 206 can both support the first support bars 203 and... The position of the first support groove 206 is adjusted by moving the adjusting screw 213 on its outer side, thereby extending and adjusting the front extension plate 201 and the rear extension plate 202. The second support bars 204 in the middle of the front extension plate 201 and the rear extension plate 202 are movably installed in the second support groove 209 in the middle of the fixing rod 207, so that the second support bars 204 are evenly supported by multiple sets of fixing rods 207. The third support bars 205 on both sides of the front extension plate 201 and the rear extension plate 202 are movably installed in the third support groove 210 in the fixing block 208, so that the multiple sets of fixing blocks 208 at the upper ends of the base frame 100 can be used to adjust the position of the first support groove 206. The third support bar 205 provides support during use. The binding hole 214 in the fixing block 208 is mainly for securing items on the upper part of the base frame 100. The fixing block 208 on the base frame 100 and the third support bar 205 on the front extension plate 201 and the rear extension plate 202 can also block the two ends of the base frame 100 to prevent items from falling after loading. The slots 215 in the front extension plate 201 and the rear extension plate 202 are mainly for reducing wind resistance. The fixing base 101 fixedly installed at the four corners of the bottom of the base frame 100 and the pressure plate 102 connected by the hexagonal screws 103 at its outer end are mainly used for fixing the base frame 100 on the upper part of the vehicle.

[0028] Working principle and usage process of this utility model:

[0029] When extending the luggage rack's usable space, first remove the adjusting screws 213 from the threaded holes 212 at the four corners of the base frame 100 to release the fixing of the front extension plate 201 and rear extension plate 202 at the front and rear ends of the base frame 100. After the front extension plate 201 and rear extension plate 202 are released, move the front extension plate 201 and rear extension plate 202 at the front and rear ends of the base frame 100 in sequence. After the front extension plate 201 and rear extension plate 202 are moved to the appropriate position, reinstall the adjusting screws 213 to fix the front extension plate 201 and rear extension plate 202 after adjustment. After the front extension plate 201 and rear extension plate 202 are moved and adjusted, the first support bar 203, the third support bar 205 and the second support bar 204 on both sides and the middle are always in the first support groove 206, the third support groove 210 and the second support groove 209 on the base frame 100, thereby providing stable and uniform support for the adjusted front extension plate 201 and rear extension plate 202 to ensure stability during use.

[0030] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
