Description

Technical Field

[0001] The utility model relates to the technical field of luggage racks, in particular to an assembly fixture for luggage racks which is easy to adjust. Background Art

[0002] A luggage rack is a support frame or component installed on the top of a car body to securely and conveniently secure luggage. A car luggage rack is both aesthetically pleasing and practical. It can not only make the car look cooler, but also be very useful when you travel. It can carry things that cannot fit in a suitcase, such as large luggage, bicycles, folding beds, etc. As long as the owner secures the cargo in place, especially if a luggage rope net is installed on the cargo, more things can be carried.

[0003] After searching, a luggage rack assembly fixture disclosed in a Chinese patent with publication number CN214686117U has the following technical points: the utility model discloses a luggage rack assembly fixture, including an assembly platform and a support rod, a movable plate is provided inside the assembly platform, and limit plates are provided at both ends of the movable plate, a positioning groove is provided on the upper surface of the assembly platform, and a plurality of clamping blocks are movably provided above the positioning groove through a first mounting plate, a plurality of first slide bars are vertically slidably connected to the first mounting plate, the upper and lower ends of the first slide bars are fixedly connected to the second mounting plate through a first mounting seat, and a cylinder is installed on the first mounting seat located above, the lower end of the cylinder is transmission-connected to the upper surface of the first mounting plate, a plurality of second slide bars are slidably connected to the lower end of the second mounting plate, both ends of the second slide bars are fixedly installed on the upper surface of the assembly platform through a second mounting seat, and a first compression spring is sleeved on the outer wall of the front end of the second slide bar. The utility model has a reasonable structural design, which enables the luggage rack to maintain a stable positioning during assembly, and improves the assembly effect and assembly efficiency.

[0004] The above scheme solves the problem of clamping and positioning the parts to be assembled, avoids the deviation between the luggage rack and the parts to be assembled during assembly, and improves the assembly effect and efficiency. However, this device cannot be adjusted according to the dimensions of the luggage rack in all directions, and has limitations. It is easy to cause luggage racks of different sizes to be unusable when they are fixed, which can easily lead to a decline in purchasing power and affect sales.
