Description

Technical Field

[0001] This utility model relates to the technical field of multifunctional car roof racks, specifically a multifunctional car roof rack. Background Technology

[0002] A roof rack is a device installed on the roof of a vehicle to store items, thereby increasing interior space. Roof racks are convenient for carrying large amounts of belongings on trips. However, installing a roof rack increases wind resistance, thus increasing fuel consumption; therefore, it should be removed if the vehicle will not be used for an extended period. Roof racks are suitable for medium to large vehicles such as commercial vehicles and SUVs.

[0003] A multi-functional car roof rack disclosed in Chinese Utility Model Patent Application Publication CN213768414U has advantages such as easy washing, powerful functions, and strong practicality. However, it also has some drawbacks: First, the roof rack lacks a fixing mechanism at the top, requiring the use of ropes to secure luggage, which may be inconvenient and difficult to maintain stability. Furthermore, it cannot be adjusted for different situations. Second, the roof rack is fixedly installed on the car roof, making disassembly inconvenient after installation. Prolonged use may lead to damage, causing inconvenience during subsequent disassembly and replacement, thus reducing user comfort. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1:

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a multifunctional car roof rack, including a crossbar 1 and a roof rack body 2. The crossbars 1 are symmetrically installed on the left and right sides. The roof rack body 2 is located directly above the two crossbars 1, and the two crossbars 1 are fixedly connected to the roof of the car. The roof rack body 2 is not connected to the crossbars 1. A first mounting block 3 and a second mounting block 4 are fixedly connected to the bottom of the roof rack body 2. Roller grooves 5 are formed on the inner sides of the first mounting block 3 and the second mounting block 4. The crossbar 1 is located between the first mounting block 3 and the second mounting block 4. Multiple roller grooves 5 are formed on the inner sides of the first mounting block 3 and the second mounting block 4. The number and position of movable rollers 6 correspond to the number of roller grooves 5. The surface of the movable rollers 6 is in contact with the two sides of the crossbar 1. The movable rollers 6, in conjunction with the first mounting block 3 and the second mounting block 4, facilitate easy installation and removal of the roof rack body 2. The movable rollers 6 are rotatably connected inside the roller grooves 5. A fixing mechanism is provided on the side of the first mounting block 3, including a fixing block 7 and a fixing... Bolt 8 and threaded hole 9 are used to fix the fixing block 7 to the front and rear inner sides of the first mounting block 3. The fixing bolt 8 is rotatably connected to the front of the fixing block 7 and passes through the fixing block 7 itself from both sides. The threaded hole 9 is opened on the outer side of the crossbar 1. The end of the fixing bolt 8 is threaded into the inside of the threaded hole 9. The fixing mechanism ensures the stable connection between the roof rack body 2 and the crossbar 1, and prevents the roof rack body 2 from shifting and causing the top objects to slip when the vehicle moves. The front and rear surfaces of the roof rack body 2 are provided with snap-fit ​​grooves 16. The snap-fit ​​groove 16 is equipped with a blocking mechanism, which includes a snap-fit ​​block 17, a stop bar 18, and a mounting bolt 19. The snap-fit ​​block 17 snaps into the inside of the snap-fit ​​groove 16. The snap-fit ​​groove 16 and the snap-fit ​​block 17 are installed in two sets facing each other. The stop bar 18 is fixedly connected between the two snap-fit ​​blocks 17. The mounting bolt 19 is rotatably connected to the front of the snap-fit ​​block 17 and its end passes through the entire snap-fit ​​block 17 and is threaded to the inner side wall of the snap-fit ​​groove 16. The blocking mechanism facilitates the blocking of objects on the roof rack body 2 from the front and rear.

[0026] When using this multifunctional car roof rack, first place the crossbar 1 between the first mounting block 3 and the second mounting block 4. Then, move the roof rack body 2 to a suitable position on the roof using the movable rollers 6 inside the roller groove 5. Next, rotate the fixing bolt 8 on the fixing block 7 so that its end is threaded into the threaded hole 9, thereby completing the fixed connection between the roof rack body 2 and the crossbar 1, so that the roof rack body 2 can be stably placed on the roof of the car. Then, the movable seat 10 on the top of the roof rack body 2 can be used with the rope to limit and fix the items to be carried. After the items are limited and fixed, the snap-fit ​​block 17 can be snapped into the snap-fit ​​groove 16, and the mounting bolt 19 can be screwed onto the front of the snap-fit ​​block 17, so that the stop bar 18 can cover the front and rear sides of the items, ensuring that the items on the top will not slip. It is very convenient and easy to use.

[0027] Example 2:

[0028] Please see Figures 1 to 6 This utility model provides a technical solution: a multifunctional car roof rack, wherein a movable seat 10 is fixedly installed on the top of the roof rack body 2, a movable groove 11 is opened on the top of the movable seat 10, a movable block 12 is slidably connected inside the movable groove 11, a threaded post 13 is threadedly connected to the top of the movable block 12, an abutment nut 14 is threadedly connected to the outside of the threaded post 13, and a limit rod 15 is fixedly connected to the top of the threaded post 13. The movable seat 10 is symmetrically installed on the left and right sides, the top of the movable block 12 is opened with a groove that matches the bottom end of the threaded post 13, the diameter of the abutment nut 14 is larger than the width of the movable groove 11, and the limit rod 15 is fixedly connected to the top of the left and right threaded posts 13 and is symmetrically installed front and back. The movable seat 10 is designed to facilitate the adjustment of the limit rod 15 on the top and to facilitate the fixing of objects on the top.

[0029] When using this multifunctional car roof rack, after the roof rack body 2 is fixedly connected, the items to be carried can first be placed on the top of the roof rack body 2 between the two movable seats 10. Then, the abutment nut 14 is turned upwards, so that the movable block 12 can slide inside the movable groove 11, driving the front and rear limit rods 15 to move. Adjust the size of the items on the roof rack body 2 to limit and fix the items. After the items are fixed, the abutment nut 14 is turned downwards so that it abuts against the top of the movable seat 10, thereby completing the fixing of the limit rods 15. This can effectively prevent the limit rods 15 from moving when the vehicle moves, thus preventing the items from falling off. It is very convenient and easy to use.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
