Description

Technical Field

[0001] This utility model relates to the field of automobile roof rack technology, specifically to an automobile roof rack connecting device. Background Technology

[0002] Generally, a car roof rack consists of mounting brackets and connecting rods. There are two sets of mounting brackets, which are respectively located at both ends of the connecting rods. In actual use, the two sets of mounting brackets are usually clamped onto the two longitudinal rods on the roof to achieve a fixed effect and ensure the stability of the roof rack on the roof.

[0003] However, in existing technologies, the mounting base is often directly fixed to the connecting rod with bolts. As a result, when actually disassembling and assembling the luggage rack, manual labor often needs to tighten or loosen the bolts from both ends of the connecting rod one by one. This operation is time-consuming and laborious, which seriously affects work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, a car roof rack connecting device is provided, which solves the problem of inconvenience in assembling and disassembling the roof rack in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a car roof rack connecting device, including a connecting rod and mounting seats detachably disposed at both ends of the connecting rod, an air passage is transversely disposed in the inner wall of the connecting rod, and plug-in components are disposed on both sides of the air passage, an air nozzle communicating with the air passage is fixed in the middle of the connecting rod body, the air nozzle has a built-in valve core, and a load-bearing reinforcing component is disposed on the mounting seat;

[0006] The insertion component includes a slide member slidably disposed in the inner cavity of the airway and an insertion rod vertically fixed to the side of the slide member facing the mounting base. The mounting base is provided with a positioning hole that matches the insertion rod.

[0007] The load-bearing reinforcement component includes a U-shaped retainer that is snapped into the end of the connecting rod, and a reinforcing rib is fixed between the retainer and the mounting base. The mounting base, the connecting rod, and the reinforcing rib form a triangular shape.

[0008] Preferably, a ring-shaped fixing member is provided on the side of the slide away from the mounting base, the outer wall of the fixing member is fixed to the inner wall of the air passage, and a spring is fixed between the fixing member and the slide.

[0009] Preferably, the bottom end of the slide is provided with a sliding opening, and a slide bar is slidably disposed in the sliding opening, the slide bar being fixedly connected to the inner wall of the air passage.

[0010] Preferably, a plug is vertically fixed on the inner wall of the bottom end of the card holder, and a slot adapted to the plug is provided on the body of the connecting rod.

[0011] Compared with the prior art, the advantages of this utility model are as follows: by setting the plug-in component, while ensuring the firmness of the connection between the connecting rod and the mounting base, it replaces the cumbersome connection method of fixing the mounting base and the connecting rod with bolts in the traditional technology. It only requires the use of an air pump to inject gas into the air passage cavity to achieve the synchronous disassembly and assembly effect between the two ends of the connecting rod and the two mounting bases, simplifying the operation steps and improving work efficiency.

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] Reference Figure 1-3 As shown, a car roof rack connecting device includes a connecting rod 1 and mounting seats 2 detachably disposed at both ends of the connecting rod 1. An air passage 3 is transversely disposed in the inner wall of the connecting rod 1. Insertion components are disposed on both sides inside the air passage 3. An air nozzle 10 communicating with the inside of the air passage 3 is fixed in the middle of the connecting rod 1. The air nozzle 10 has a valve core inside. A load-bearing reinforcing component is disposed on the mounting seat 2.

[0019] The insertion component includes a slide 4 that is slidably disposed in the inner cavity of the airway 3 and an insertion rod 5 that is vertically fixed on the side of the slide 4 facing the mounting base 2. The mounting base 2 is provided with a positioning hole 6 that is adapted to the insertion rod 5. A ring-shaped fixing member 8 is provided on the side of the slide 4 away from the mounting base 2. The outer wall of the fixing member 8 is fixed to the inner wall of the airway 3, and a spring 9 is fixed between the fixing member 8 and the slide 4.

[0020] By using the plug-in components, when assembling the luggage rack, the connecting rod 1 is pre-positioned horizontally between the two mounting bases 2. Then, an air pump is connected to the air nozzle 10, and the air pump continuously injects gas into the air passage 3. The sliding parts 4 on both sides of the air passage 3 can then be simultaneously carried by the air pressure, sliding the plug-in rod 5 towards one side of the mounting base 2 until the plug-in rod 5 passes into the positioning hole 6. Finally, the two mounting bases 2 can be fixedly connected to the two ends of the connecting rod 1. During this process, the sliding parts 4 can simultaneously stretch and deform the spring 9. Therefore, the elastic force of the spring 9 is used to release the gas inside the air passage 3 later using the ejector pin. At the same time, the sliding parts 4 on both sides inside the air passage 3 can simultaneously carry the plug rod 5 to quickly reset, so that the plug rod 5 is disengaged from the positioning hole 6, and the fixing effect between the mounting base 2 and the connecting rod 1 is also removed. In this way, while ensuring the firmness of the connection between the connecting rod 1 and the mounting base 2, it replaces the cumbersome connection method of fixing the mounting base 2 and the connecting rod 1 with bolts in the traditional technology. Only by using an air pump to inject gas into the inner cavity of the air passage 3, the simultaneous disassembly and assembly of the two ends of the connecting rod 1 and the two mounting bases 2 can be achieved, simplifying the operation steps and improving work efficiency.

[0021] Furthermore, referring to Figure 1-3 As shown, it is worth noting that the load-bearing reinforcement component includes a U-shaped retainer 11 that is clamped at the end of the connecting rod 1, and a reinforcing rib 12 is fixed between the retainer 11 and the mounting base 2. The mounting base 2, the connecting rod 1, and the reinforcing rib 12 form a triangular shape.

[0022] With the addition of the load-bearing reinforcement component, when the connecting rod 1 is horizontally mounted between the two mounting bases 2, the end of the connecting rod 1 can be simultaneously inserted into the mounting base 11 in the load-bearing reinforcement component. In this way, the end of the connecting rod 1 can be supported by the mounting base 11, which provides auxiliary positioning for the end of the connecting rod 1, so that the end of the connecting rod 1 and the mounting base 2 are fully matched, which facilitates the subsequent use of the plug-in component to finally fix the connecting rod 1 and the mounting base 2.

[0023] Furthermore, by utilizing the reinforcing rib 12, a stable triangular shape is formed between the mounting base 2, the connecting rod 1, and the reinforcing rib 12, thereby enhancing the bearing capacity of the end of the connecting rod 1 and improving the firmness between the end of the connecting rod 1 and the mounting base 2.

[0024] Furthermore, referring to Figure 2 As shown, it is worth noting that a plug 13 is vertically fixed on the inner wall of the bottom end of the card holder 11, and a slot adapted to the plug 13 is provided on the body of the connecting rod 1.

[0025] By setting the reinforcing rib 12 and the slot, when the end of the connecting rod 1 is inserted into the card seat 11, the insert 13 is simultaneously embedded into the slot. With the insert 13 and the slot, the mounting seat 2 can be prevented from falling off the connecting rod 1 when it is pulled laterally, thus further enhancing the connection strength between the connecting rod 1 and the mounting seat 2.

[0026] Furthermore, referring to Figure 2 As shown, it is worth noting that the bottom end of the slide 4 is provided with a sliding opening, and a slide bar 7 is slidably disposed in the sliding opening. The slide bar 7 is fixedly connected to the inner wall of the air passage 3.

[0027] By setting the slider 7, when the slider 4 slides under air pressure, the slider 4 can slide synchronously on the slider 7. In this way, the slider 7 can effectively limit the movement trajectory of the slider 4 and ensure the stability of the slider 4 during movement.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
