Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, in particular to an expansion hook structure for a roof cross bar. Background Art
[0002] SUV models generally have a luggage rack (longitudinal rail) pre-installed on their roofs. Accessories manufacturers manufacture special roof luggage boxes according to the size and structure of the luggage racks. Users can directly install the purchased roof luggage boxes on the luggage racks when using them. However, special roof luggage boxes are not universal, and because the mold opening fee is expensive, this part of the cost will eventually be passed on to the user, resulting in the low compatibility and cost-effectiveness of special roof luggage boxes. Therefore, users are increasingly inclined to choose universal roof cross bars (cross rails). Chinese utility model patent CN219728038U discloses a roof cross bar assembly and a roof cross bar. In order to solve the problem that the existing roof cross bars are easy to scratch the luggage rack, it proposes a solution of a cross bar body made of hard rubber and plastic foam.
[0003] However, the installation method of the above-mentioned roof crossbar still requires the cooperation of the luggage rack, because when the roof crossbar is used, the two ends of the webbing need to be connected end to end to provide a reliable annular connection relationship for the crossbar body. Obviously, the two ends of the webbing need to pass under the luggage rack when fixed. For models without luggage racks (such as sedans), this product cannot be used. If the two ends of the above-mentioned webbing are forced to pass through the car and connect end to end, the webbing will be exposed inside the car and may hit the passenger's head, which is not a reasonable design.
[0004] In summary, compared with dedicated roof luggage boxes, roof cross bars made of hard rubber and plastic foam are indeed a more convenient and universal alternative product, but they cannot be adapted to cars without luggage racks, such as sedans, which limits their scope of application.

DETAILED DESCRIPTION
[0020] In order to make the purpose, technical solution and advantages of the utility model clearer and more specific, the content of the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the utility model, rather than to limit the utility model. It should also be noted that, for the convenience of description, only the parts related to the utility model are shown in the accompanying drawings, rather than all the contents.
[0021] This embodiment proposes an expansion hook structure for a roof crossbar, such as Figure 1 As shown, it includes a first webbing 1 for fixing to a roof cross bar 100, and adjustable hook assemblies 2 are respectively provided at both ends of the first webbing 1, and a second hook 3 for hanging with a door frame of a target vehicle, wherein the adjustable hook assembly 2 includes a lock buckle 21 connected to one end of the first webbing 1, and the other end of the lock buckle 21 is connected to a second webbing 22, and a first hook 4 for hanging with a door frame of a target vehicle is provided at the end of the second webbing 22.
[0022] In this embodiment, when in use, the roof cross bar 100 with the first webbing 1 is first placed on the roof of the target vehicle, and the second hook 3 and the first hook 4 are respectively hung on the two door frames of the target vehicle. By adjusting the length of the first webbing 1 and fixing the first webbing 1 with the adjustable hook assembly 2, the roof cross bar 100 is fixed to the roof of the target vehicle. This hook structure is suitable for vehicles without luggage racks, which increases the application range of the roof cross bar.
[0023] It should be noted that the target vehicle door frame in this embodiment can be any mass-produced SUV model or sedan model door frame, and the outside of the door frame is covered with a sealing strip (not shown in the figure), so the sealing strip needs to be pulled open first to expose the top edge of the door frame, so as to hang the first hook 4 / the second hook 3 on the edge of the door frame 200, as shown in FIG. Figure 2 When the first hook 4 / the second hook 3 is installed, the sealing strip is fastened to the top edge of the door frame.
[0024] Obviously, when the adjustable hook assembly 2 and the second hook 3 are pre-installed on both ends of the first webbing 1, the first webbing 1 will not be able to pass through the roof cross bar 100, so the device can be pre-installed on the roof cross bar 100 as a component. In order to improve the flexibility of the product, the second hook 3 and / or the first hook 4 are detachable. When the user needs to replace the first webbing 1, the user can remove one or both of the second hook 3 and the first hook 4 by himself, providing a basis for the first webbing 1 to withdraw from the roof cross bar 100.
[0025] The lock buckle 21 can be any locking member that can fix the first webbing 1, such as Figure 3 As shown, the lock buckle 21 includes a fixing member 211, and a buckle 212 hingedly installed inside the fixing member 211, and a channel 213 is formed between the buckle 212 and the side wall of the fixing member 211, and the channel 213 is used to accommodate the first webbing 1. When adjusting the tightness of the first webbing 1, one end of the first webbing 1 needs to enter from the bottom of the channel 213 and pass through the top of the channel 213, and the user needs to pull the first webbing 1 upward to ensure that the first webbing 1 is straightened, and finally the first webbing 1 is fixed with the buckle 212.
[0026] In order to improve the reliability of the lock buckle 21, a preferred solution is provided in this embodiment to ensure that the first webbing 1 will not loosen during use. Figure 4 As shown, the buckle 212 comprises a hinge 2121 installed inside the fixing member 211, and the outer surface of the hinge 2121 is radially provided with an unlocking block 2122 and a clamping block 2123 which diverge at an obtuse angle, and the space between the clamping block 2123 and the side wall of the fixing member 211 is defined as a channel 213, and the width of the channel 213 is less than the thickness of the first webbing 1. In this scheme, when the tightness of the first webbing 1 is required, the user needs to first push the unlocking block 2122 toward the direction of the roof cross bar 100, and at this time, the clamping block 2123 rotates clockwise synchronously, and the width of the channel 213 increases, so that the end of the first webbing 1 can smoothly enter the channel 213, and then immediately push the unlocking block 2122 in the opposite direction, and the clamping block 2123 rotates counterclockwise synchronously to clamp the first webbing 1, and an effective fixation is formed by interference clamping. More importantly, after the clamping block 2123 clamps the first webbing 1, no matter it is subjected to external vibration or the user actively tears the first webbing 1 downwards, the first webbing 1 will not loosen, but will be clamped tighter and tighter by the clamping block 2123, similar to the effect of a ratchet.
[0027] Optional, continue to Figure 3The adjustable hook assembly 2 also includes a third webbing 23, the two ends of which are respectively connected to the first webbing 1 and the second webbing 22, and the third webbing 23 is located directly below the lock buckle 21. The third webbing 23 has two functions: the first is to isolate the lock buckle 21 from the paint surface of the roof to prevent the lock buckle 21 from scratching the paint, and the second is to improve the connection strength between the first webbing 1 and the second webbing 22.
[0028] Furthermore, Figure 5 As shown, a fixing groove 231 is opened in the middle of the third webbing 23. Before the first webbing 1 is connected to the buckle 21, one end of the first webbing 1 enters from the bottom of the fixing groove 231 and passes through the top of the fixing groove 231 in sequence. This setting method can limit the installation position of the first webbing 1 and prevent the first webbing 1 from shaking left and right.
[0029] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable ordinary technicians in the field to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the essence of the content of the utility model should be included in the protection scope of the utility model.
