Description

Technical Field

[0001] The utility model relates to the technical field of trailer frame fixing devices, in particular to a vehicle-mounted bicycle fixing device. Background Art

[0002] The vehicle-mounted bicycle fixing device is suitable for car owners who like to ride outdoors during travel. The bicycle rack fixed on the rear tailgate is also called a backpack bicycle rack. The backpack bicycle rack is connected to the sheet metal gap of the rear tailgate by a metal hook, keeping the roof free for loading other equipment. The higher-positioned model allows the rear lights to be always visible. The advantage is that it is more convenient to take and put bicycles than a roof-mounted bicycle rack, and it is the preferred choice of most car owners.

[0003] At present, the fixing devices for bicycles on vehicles mostly use a combination of a wheel trailer and a cassette for setting up and fixing. However, it is worth noting that during the loading process, if the user slips and causes the bicycle to shift, the wheel of the bicycle will slide out, thereby reducing the protection of the fixing device on the side stops of the bicycle on the vehicle. Utility Model Content

[0004] The purpose of the utility model is to provide a vehicle-mounted bicycle fixing device, which solves the technical problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vehicle-mounted bicycle fixing device, comprising a connecting bracket, a lower bracket is welded to the surface of one side of the connecting bracket, an upper bracket is detachably sleeved on the surface of the lower bracket, connecting bracket sleeves are fixedly sleeved on both ends of the upper bracket, a group of symmetrical supporting frames are plug-connected inside the connecting bracket sleeves, and a group of symmetrical vehicle brackets are fixedly connected to the upper end surface of any group of the supporting frames, a toothed belt for fastening wheels is connected to the vehicle brackets, a group of limiting plates are symmetrically fixedly connected to the inside of one side of the supporting frame, a limiting rod is fixedly connected between the two limiting plates, a displacement sleeve is threadedly sleeved on the external surface of the adjusting screw, an opening for the limiting rod to slide and pass through is opened on the side of the displacement sleeve, and a side arc baffle is fixedly connected to the surface of one side of the displacement sleeve.

[0006] Optionally, a handlebar rod is connected to a surface close to the center of one side of the vehicle bracket close to the connecting bracket.

[0007] Optionally, both side surfaces of the supporting frame close to the lower bracket are hinged to the lower bracket with a rotating shaft for folding.

[0008] Optionally, a stabilizing clamp is symmetrically mounted and connected to the surface of the handle frame rod.

[0009] Optionally, inner surfaces of the side baffles all abut against the wheel of the bicycle.

[0010] Optionally, a temporary license plate frame is fixedly connected to the upper bracket away from the central surface of the connecting bracket, and a threaded hole is provided on the surface of the temporary license plate frame for facilitating installation and removal of the license plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model utilizes the side arc baffle plate that is adjustable on one side of the fixing bracket, so that when the user loads the bicycle, the side arc baffle plates on both sides can be used for loading operation to prevent lateral sliding from occurring. Secondly, the user can also manually rotate the adjustment handle according to the specific loading position of the bicycle, and the adjustment handle drives the adjustment screw to perform threaded rotation between the limit plates. The displacement sleeve sleeved outside the adjustment screw will also drive the side arc baffle plate to approach the wheel part of the bicycle under the limiting action of the limit rod until it hits the wheel part of the bicycle, thereby ensuring the flexible adjustment of the side baffle protection operation, thereby improving the dual effect of the fixing protection of the fixing device.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] For example, see Figures 1 to 5 The utility model provides a technical solution: a vehicle-mounted bicycle fixing device, comprising a connecting bracket 1, a lower bracket 2 is welded to the surface of one side of the connecting bracket 1, an upper bracket 3 is detachably sleeved on the surface of the lower bracket 2, and can be detachably connected together by bolts, connecting frame sleeves 5 are fixedly sleeved at both ends of the upper bracket 3, a group of symmetrical supporting frames 4 are plug-connected inside the connecting frame sleeves 5, a group of symmetrical vehicle brackets 7 are fixedly connected to the upper end surface of any group of supporting frames 4, a handlebar rod 6 is connected to the surface of the vehicle bracket 7 close to the center of the side of the connecting bracket 1, and a toothed cassette 10 for fastening the wheel is connected to the vehicle bracket 7.

[0023] In this embodiment, the connecting bracket 1 is installed and connected to the rear of the car. The user can use the bicycle bracket 7 and the toothed cassette 10 to lock the wheel of the bicycle in the bicycle bracket 7 by the toothed cassette 10, so as to achieve the purpose of stably loading the bicycle on the trailer frame.

[0024] Furthermore, since a group of limit plates 15 are symmetrically fixedly connected to the inside of one side of the supporting frame 4, the limit plates 15 are internally through-through limited rotationally connected with an adjusting screw 16, one end of the adjusting screw 16 is connected to an adjusting handle 20, a limit rod 17 is fixedly connected between the two limit plates 15, the external threaded sleeve of the adjusting screw 16 is connected with a displacement sleeve 18, the side of the displacement sleeve 18 is provided with an opening for the limit rod 17 to slide and pass through, and a side arc plate 19 is fixedly connected to the surface of one side of the displacement sleeve 18, and the inner surfaces of the side arc plate 19 are all in contact with the wheel of the bicycle.

[0025] More specifically, when the user is loading a bicycle, the side arc plates 19 on both sides can be used for loading operations to prevent lateral sliding. Secondly, the user can also manually rotate the adjustment handle 20 according to the specific loading position of the bicycle. The adjustment handle 20 drives the adjustment screw 16 to rotate between the limit plates 15. The displacement sleeve 18 sleeved on the outside of the adjustment screw 16 will also drive the side arc plates 19 to approach the wheel of the bicycle under the limiting action of the limit rod 17 until it hits the wheel of the bicycle, ensuring the flexible adjustment of the side guard protection operation, thereby improving the dual effect of the fixing protection of the fixing device.

[0026] Furthermore, both side surfaces of the supporting frame 4 close to the lower bracket 2 are hingedly connected to the lower bracket 2 with a rotating shaft 11 for folding.

[0027] It is worth noting that the vehicle brackets 7 and the supporting frame 4 on both sides can be folded inward by rotating the shaft 11, which is convenient for users to disassemble and store.

[0028] Embodiment 2, based on the above embodiment:

[0029] Furthermore, a temporary license plate frame 8 is fixedly connected to the central surface of the upper bracket 3 away from the connecting bracket 1, and a threaded hole 9 is provided on the surface of the temporary license plate frame 8 for facilitating the installation and removal of the license plate.

[0030] More specifically, in this embodiment, since the vehicle-mounted bicycle fixing device is installed, the license plate of the vehicle itself is easily blocked. Therefore, during the use of the fixing device, the user can thread the vehicle license plate to the position of the temporary license plate frame 8 through the threaded hole 9, thereby avoiding the situation where the electronic eye cannot recognize the vehicle information. Moreover, after folding, it can rotate with the frame to reduce the occupied space. For details, see the folded state Figure 7 .

[0031] In addition, since the surface of the handle frame rod 6 is symmetrically mounted and connected with a fixing clamp 12, as shown in FIG. Figure 7 As shown, a crossbeam for clamping and fixing a bicycle is provided with two stabilizing clamps 12, each of which is used to fix one bicycle. The stabilizing clamps 12 cooperate with the toothed cassette 10 to achieve high and low matching to better fix the vehicle, thereby preventing the bicycle from tipping over.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
