Description

Technical Field

[0001] This utility model relates to the field of luggage rack technology, specifically a luggage rack fixing structure. Background Technology

[0002] As an indispensable and important extension component on the roof of a vehicle, the car roof rack plays a key role in enhancing the vehicle's practicality and expandability. It is usually composed of a carefully designed combination of horizontal and vertical bars, which work together to form a stable load-bearing platform, providing valuable extra space for various items such as bicycles, suitcases, and kayaks. This greatly meets the travel needs of people in diverse scenarios such as self-driving tours and outdoor sports. With this unique function, car roof racks have been widely used in SUVs, MPVs and other models, becoming a popular choice for many car owners to enhance the functionality and personalization of their vehicles.

[0003] However, most existing fixing structures use pre-sized clips or bolts for connection. This design concept is often optimized only for connecting rods of specific specifications in the early stages of development. When faced with a wide variety of different car models on the market, or when users customize their vehicles for personalized needs, the differences in diameter, length, and cross-sectional shape of the connecting rods will result in a serious mismatch between the fixing parts and the rod body. This mismatch directly leads to loosening during installation, which not only affects the normal use of the luggage rack, but may also force users to purchase additional matching parts, increasing the cost of use and time. Therefore, we propose a luggage rack fixing structure. Utility Model Content

[0004] The purpose of this utility model is to provide a luggage rack fixing structure to solve the problem mentioned in the background art that the existing fixing structure cannot be adapted to different specifications of connecting rods due to the preset size, resulting in loose installation and increased use costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a luggage rack fixing structure, comprising: a luggage rack body and two connecting rods, the lower ends of the two connecting rods being fixedly connected to the roof of a car;

[0006] It also includes: several fixing components, which are set at the lower part of the luggage rack body. The fixing components are used to fix the luggage rack body to the connecting rod. The fixing components include a connecting block fixedly connected to the lower end of the luggage rack body.

[0007] The clamping assembly includes a first clamping block fixedly connected to the lower end of the first slider, a second slider slidably connected to the inner cavity of the first clamping block, guide rods symmetrically fixedly connected to the inner cavity of the first clamping block, the second slider slidably connected to the two guide rods, the lower end of the second slider fixedly connected to the second clamping block, and a spring wound around the outer surface of the guide rod. The two sides of the spring are respectively fixedly connected to the lower side of the inner cavity of the first clamping block and the upper part of the second slider.

[0008] The connecting block has a first sliding groove symmetrically opened on one side, and the inner cavity of the first sliding groove is connected to the inner cavity of the connecting block. The first slider is fixedly connected to the first screw on the side near the first sliding groove. The first screw is slidably connected to the inner cavity of the first sliding groove. The first screw is threadedly connected to a nut on the side away from the first slider.

[0009] The luggage rack body has a second slide groove symmetrically opened on one side. The inner cavity of the second slide groove is slidably connected to a first slide plate. The two first slide plates are fixedly connected to an extension plate on the side away from the luggage rack body. The side of the extension plate close to the luggage rack body is symmetrically fixedly connected to a second slide plate. The luggage rack body is slidably connected to the two second slide plates.

[0010] The luggage rack body is rotatably connected to a second screw in the middle. An anti-slip block is fixedly connected to the side of the second screw away from the extension plate.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1 to 7 This utility model provides a technical solution: a luggage rack fixing structure, including: a luggage rack body 3 and two connecting rods 1, the lower ends of the two connecting rods 1 being fixedly connected to the roof of the car;

[0026] It also includes: several fixing components 2, which are set at the lower part of the luggage rack body 3. The fixing components 2 are used to fix the luggage rack body 3 to the connecting rod 1. The fixing components 2 include a connecting block 21 fixedly connected to the lower end of the luggage rack body 3. A bidirectional threaded rod 23 is rotatably connected to the middle of the connecting block 21. A first slider 24 is symmetrically slidably connected to the inner cavity of the connecting block 21. The bidirectional threaded rod 23 is threadedly connected to two first sliders 24. A clamping component 25 is fixedly connected to the lower end of each first slider 24.

[0027] By providing a connecting block 21, the luggage rack body 3 can be fixedly connected to the connecting block 21, thereby supporting the luggage rack body 3. After fixing the position of the fixing component 2, the position of the luggage rack body 3 can be fixed, making it easy to install the luggage rack body 3 on the roof of the car. The first sliders 24 are symmetrically arranged in the inner cavity of the connecting block 21, and then the two first sliders 24 are threadedly connected to the two first sliders 24 by a bidirectional threaded rod 23. The lower end of each first slider 24 is fixedly connected to a clamping component 25. When the bidirectional threaded rod 23 is rotated, the two first sliders 24 can be driven to slide in the inner cavity of the connecting block 21 towards the opposite face, and then the two clamping components 25 can be driven to slide towards the connecting rod 1, and then the two clamping components 25 can be driven to clamp the connecting rod 1, thereby installing the luggage rack body 3 together with the car. This improves the practicality and flexibility of the device and reduces the cost of use and time.

[0028] The clamping assembly 25 includes a first clamping block 251 fixedly connected to the lower end of the first slider 24, a second slider 252 slidably connected to the inner cavity of the first clamping block 251, guide rods 253 symmetrically fixedly connected to the inner cavity of the first clamping block 251, the second slider 252 slidably connected to the two guide rods 253, a second clamping block 255 fixedly connected to the lower end of the second slider 252, a spring 254 wound around the outer surface of the guide rods 253, the two sides of the spring 254 being fixedly connected to the lower side of the inner cavity of the first clamping block 251 and the upper part of the second slider 252 respectively, a first sliding groove 22 symmetrically opened on one side of the connecting block 21, and the inner cavity of the first sliding groove 22 communicating with the inner cavity of the connecting block 21, a first screw 221 fixedly connected to the side of the first slider 24 near the first sliding groove 22, the first screw 221 slidably connected to the inner cavity of the first sliding groove 22, and a nut 222 threadedly connected to the side of the first screw 221 away from the first slider 24.

[0029] When the roof rack body 3 needs to be installed on the roof of the car, first place the roof rack body 3 on the upper ends of the two connecting rods 1. Then, the user rotates the bidirectional threaded rod 23. Since the first slider 24 is threadedly connected to the bidirectional threaded rod 23, the rotation of the bidirectional threaded rod 23 can drive the first slider 24 to move. Under the action of the bidirectional threaded rod 23, the two first sliders 24 can be driven to move towards the opposite face. When the first sliders 24 move, the clamping assembly 25 can be driven to move towards the connecting rod 1. Then, when the clamping assembly 25 contacts the connecting rod 1, a force is applied to the second clamping block 255, causing the second clamping block 255 to move downward, preventing the second clamping block 255 from colliding with the connecting rod 1 during the movement of the clamping assembly 25. The movement of the clamping assembly 25 is affected by the force applied to the second clamping block 255, which can position the connecting rod 1 on the upper part of the second clamping block 255. The second clamping block 255 drives the second slider 252 to slide downward in the inner cavity of the first clamping block 251. Then, the second slider 252 can apply a force to the spring 254, causing the spring 254 to contract. When the user releases the force applied to the second clamping block 255, it can extend under the elastic force of the spring 254, which can then drive the second slider 252 to slide upward in the inner cavity of the first clamping block 251. This allows the second clamping block 255 to slide upward, so that the upper part of the second clamping block 255 can contact the lower part of the connecting rod 1, thereby clamping the connecting rod 1 at multiple angles and improving the stability during the clamping process.

[0030] When the first slider 24 moves, it can drive the first screw 221 to move in the opposite direction within the inner cavity of the first groove 22. After the first slider 24 stops moving, the user can apply force to the nut 222 to drive the nut 222 to move towards the connecting block 21. When the nut 222 contacts the connecting block 21, the friction between the nut 222 and the connecting block 21 can be used to limit the position of the first screw 221. Then, the first screw 221 can be used to limit the position of the first slider 24, preventing the first slider 24 from moving accidentally and affecting the fixation of the device.

[0031] Example 2

[0032] The luggage rack body 3 has symmetrically arranged second slide grooves 33 on one side. First slide plates 41 are slidably connected to the inner cavity of each second slide groove 33. An extension plate 4 is fixedly connected to the side of the two first slide plates 41 away from the luggage rack body 3. Second slide plates 42 are symmetrically fixedly connected to the side of the extension plate 4 near the luggage rack body 3. The luggage rack body 3 is slidably connected to the two second slide plates 42. A second screw 35 is rotatably connected to the middle of the luggage rack body 3. An anti-slip block 36 is fixedly connected to the side of the second screw 35 away from the extension plate 4. An anti-slip block 36 is fixedly connected to the side of the extension plate 4 near the luggage rack body 3. A limiting block 43 is fixedly connected to the middle side. The luggage rack body 3 is slidably connected to the limiting block 43. The second screw 35 is threadedly connected to the limiting block 43. A third slide groove 34 is symmetrically opened on the side of the luggage rack body 3 near the extension plate 4. The inner cavity of the second slide groove 33 on the same side is connected to the inner cavity of the third slide groove 34. The limiting block 43 is slidably connected to the inner cavity of the third slide groove 34. The first slide plate 41 on the same side is fixedly connected to the limiting block 43. An operation groove 31 is symmetrically opened on the upper part of the side of the luggage rack body 3 near the extension plate 4. A bolt 32 is threadedly connected to the inner cavity of the operation groove 31.

[0033] When the distance between the luggage rack body 3 and the extension plate 4 needs to be adjusted according to requirements, the user can rotate the anti-slip block 36, which in turn drives the second screw 35 to rotate. Since the second screw 35 is threadedly connected to the limiting block 43, when the second screw 35 rotates, it can drive the limiting block 43 to slide towards one side of the extension plate 4, and then drive the extension plate 4 to slide away from the luggage rack body 3. The extension plate 4 can then drive the first sliding plate 41 to slide within the adjacent second sliding groove 33. When the first slide plate 41 moves, it will cause the limiting block 43 to slide in the inner cavity of the adjacent third slide groove 34. Through the cooperation of the third slide groove 34 and the limiting block 43, the position of the first slide plate 41 in the inner cavity of the second slide groove 33 can be limited, thereby preventing the luggage rack body 3 from completely separating from the extension plate 4. After determining the position of the extension plate 4, the operating bolt 32 is rotated, and the lower end of the bolt 32 contacts the upper end of the first slide plate 41. The friction force can be used to limit the position of the first slide plate 41 in the inner cavity of the second slide groove 33.
