[0032] One or more examples of the present application are shown in the accompanying drawings. The detailed description uses numbers and letter marks to refer to features in the drawings. Similar or similar marks in the drawings and description have been used to refer to similar or similar parts of the present application. As used herein, the terms "first", "second", and "third", etc. are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of individual components.

[0033] like Figures 1 to 7 As shown, according to an embodiment of the present application, a two-wheel bracket is provided, including a first frame tube fork 1, which has a first wheel frame 11 and a first tube fork 12; a second frame tube fork 3, which has a second wheel frame 31 and a second tube fork 32. The modular design of the first frame tube fork 1 and the second frame tube fork 3 improves the versatility and flexibility of the two-wheel bracket. The first wheel frame 11 and the second wheel frame 31 are parallel structural members with wheel clamping. By designing the first wheel frame 11 and the second wheel frame 31 as parallel structural members with wheel clamping, the two-wheel bracket can firmly fix a bicycle or similar means of transportation, ensure the stability of the items during driving, reduce the displacement caused by bumps, and at the same time, the parallel structure can evenly distribute the load and improve the load-bearing capacity. The first end and the second end of the support frame 24 are respectively provided with a first pipe clamp 21 and a second pipe clamp 22. The first pipe fork 12 and the support frame 24 are fixed by the first pipe clamp 21, and the second pipe clamp 22 and the support frame 24 are fixed by the second pipe clamp 22. The support frame 24 and the first wheel frame 11 and the second wheel frame 31 are fixed by the first pipe clamp 21 and the second pipe clamp 22, which ensures the fixation of the wheel position and the overall stability of the double-wheel bracket. The first pipe clamp 21 and the second pipe clamp 22 not only ensure the firm connection between the first frame pipe fork 1 and the second frame pipe fork 3 and the support frame 24, but also accurately control the spacing between the first wheel frame 11 and the second wheel frame 31 by the way of limiting and fixing, ensure the appropriate spacing between the wheels or the loaded objects, avoid mutual collision or friction, and improve safety and loading efficiency.

[0034] The main bracket 2 includes a support frame 24 and a fixing frame 23 connected to the support frame 24. The first end of the support frame 24 is detachably plugged into the first tube fork 12, and the second end of the support frame 24 is detachably plugged into the second tube fork 32. The detachable plug-in design of the first frame tube fork 1, the second frame tube fork 3 and the main bracket 2 makes the installation and disassembly of the two-wheel bracket simple and quick, which is convenient for the adaptation of different vehicle models and daily maintenance and storage. The above-mentioned limited fixing structure simplifies the installation process, and the user can quickly complete the installation and adjustment of the two-wheel bracket without complicated tools or professional knowledge, thereby improving the user experience.

[0035] The vertical rod tube 4 is vertically connected to the main support 2. It provides additional vertical support for the two-wheel bracket, so that the vertical rod tube 4 and the first tube fork 12 and the second tube fork 32 form a triangular structure, which enhances the overall structural stability of the two-wheel bracket. Especially when carrying heavy objects or large items, the vertical rod tube 4 can effectively prevent the shaking or deformation of the two-wheel bracket, thereby improving the carrying capacity. The vertical rod tube 4 is detachably connected to the fixing frame 23 through the vertical rod tube fixing 5. The height and position of the vertical rod tube 4 can be adjusted according to actual needs to adapt to different height vehicle models, thereby improving the flexibility and adaptability of the two-wheel bracket and meeting the needs of different scenes and loads. The design of the vertical rod tube 4 and its fixings not only provides additional vertical support for the two-wheel bracket, but also provides the possibility of mounting additional accessories (such as lamps, suitcases, etc.), thereby enhancing the versatility and adaptability of the two-wheel bracket.

[0036] The vertical pole tube fixing member 5 includes a pipe fitting 55, a vertical pole tube clamp 51 is provided at the end of the pipe fitting 55, and the vertical pole tube 4 is inserted into the pipe fitting 55 and fixed by the vertical pole tube clamp 51. The pipe fitting 55 of the vertical pole tube fixing member 5 is used in combination with the vertical pole tube clamp 51, and the vertical pole tube 4 is ensured to be stable by the limited fixing method, and loosening due to vibration or wind resistance during driving is prevented, thereby improving the safety of the two-wheel bracket.

[0037] The vertical pole tube fixing member 5 also includes a sleeve clamping member 52, and the fixing frame 23 is detachably connected to the vertical pole tube fixing member 5 through the pipe through hole 53 on the sleeve clamping member 52. The sleeve clamping member 52 is also provided with a through hole 54, and when the vertical pole tube fixing member 5 is connected to the fixing frame 23, the vertical pole tube fixing member 5 and the fixing frame 23 can be locked and fixed by passing a bolt through the through hole 54. The cooperation between the pipe through hole 53 on the sleeve clamping member 52 and the fixing frame 23, and the mechanism of locking and fixing by passing a bolt through the through hole 54, make the connection between the vertical pole tube fixing member 5 and the fixing frame 23 both stable and easy to disassemble, simplify the installation and disassembly process, and improve the convenience of use.

[0038] The support frame 24 is perpendicularly connected to the fixing frame 23 in a T-shape, and a reinforcing rib plate 25 is provided at the connection point between the support frame 24 and the fixing frame 23. This structure not only optimizes the structural layout of the two-wheel bracket, but also improves the overall anti-bending and anti-torsion capabilities of the two-wheel bracket by increasing the local strength, thereby ensuring the stability of the structure when bearing loads.

[0039] One application step of the utility model is as follows:

[0040] In the first step, one end of the main bracket 2 of the double-wheel bracket is installed at the rear of the vehicle, and then the main bracket 2 is ensured to be correctly connected with the first frame tube fork 1 and the second frame tube fork 3. The first tube clamp 21 and the second tube clamp 22 respectively limit and fix the first tube fork 12 and the second tube fork 32 to ensure that the spacing distance between the first wheel frame 11 and the second wheel frame 31 is correct.

[0041] Connect the vertical pole tube 4 to the main support 2 vertically, and connect it to the fixing frame 23 detachably through the vertical pole tube fixing piece 5, and ensure that the vertical pole tube 4 is inserted into the pipe 55 and fixed by the vertical pole pipe clamp 51. Use the pipe through hole 53 on the sleeve clamp 52 to connect the fixing frame 23 to the vertical pole tube fixing piece 5, and lock and fix it by bolts passing through the through hole 54 to ensure that all parts are stable.

[0042] Step 2: Load the bike

[0043] Place the rear wheel of the bicycle 6 in the clamping structure of the first wheel frame 11, and the front wheel in the clamping structure of the second wheel frame 31. Make sure that the wheels of the bicycle 6 are completely located in the grooves of the wheel frames to prevent sliding during driving. Adjust the distance between the first wheel frame 11 and the second wheel frame 31 according to the width of the bicycle 6 to ensure that the bicycle 6 is in a stable state on the two-wheel bracket. Check whether the bicycle 6 is firmly fixed on the two-wheel bracket by gently shaking the bicycle manually to confirm that it has no obvious shaking on the two-wheel bracket.

[0044] Step 3: Confirm safety

[0045] After loading, check whether all connection parts are tight, especially the connection between the upright tube 4 and the fixing frame 23, and the T-shaped connection point between the support frame 24 and the fixing frame 23, to ensure that the reinforcing rib plate 25 provides sufficient support. Confirm that the loading of the bicycle will not block the rearview mirror or taillight of the vehicle to ensure driving safety.

[0046] Step 4: Reinforcement

[0047] After confirming safety, the bicycle 6 can also be further reinforced with a binding belt 7 to make the bicycle 6 more stable on the two-wheel bracket. The binding belt 7 can also be replaced with similar binding belts, ropes, etc.

[0048] Step 5: Check before driving

[0049] Before you start riding, check the bike's securement again to make sure nothing will come loose or fall off during riding.

[0050] The above description is only some embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
