Description

Technical Field

[0001] The utility model belongs to the technical field of bicycles, and in particular relates to a front supporting device for a bicycle. Background Art

[0002] Bicycles, also known as bicycles or bikes, can be used as an environmentally friendly means of transportation for travel. In order to facilitate users to place the items they carry, a basket is usually installed in front of the front of the bicycle to increase the storage function of the bicycle. The bicycle front support device is a fixing device when the basket is installed, which can provide stable support for the basket and ensure the safety of the stored items.

[0003] However, the existing front support device of a bicycle is generally a fixed plate with a simple structure. The simple fixed plate may not be able to withstand heavier loads. When the basket is loaded with too many items, the support plate may bend or break. At the same time, on uneven roads or when riding at high speeds, the fixed plate may not provide sufficient stability, increasing the risk of the bicycle tipping over. Secondly, the design of the fixed plate may not be able to adapt to baskets of different sizes and shapes, limiting its versatility. Based on the above problems, this application document proposes a front support device for a bicycle to improve the above problems. Utility Model Content

[0024] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0025] like Figure 1 As shown, a front support device for a bicycle comprises a main frame 10, through holes are provided on both sides of the lower end of the main frame 10, a U-shaped frame 11 is fixed between the two through holes, a support plate 12 is fixed to one end of the main frame 10 and close to the U-shaped frame 11, a first support seat 20 is fixed to the upper end of the support plate 12 and away from the main frame 10, a second support seat 21 is threadedly connected to the upper end of the support plate 12 and close to the first support seat 20, a fixing plate 25 is fixed to the upper end of the second support seat 21, and the first support seat 20 is fixed to the upper end of the second support seat 21. A basket 23 is fixed at the upper end, a first groove is formed at the lower end of the support plate 12 and at one end away from the main frame 10 of the vehicle body, and the upper end of the U-shaped frame 11 is fixed in the first groove. The triangular structure formed by the main frame 10, the U-shaped frame 11 and the support plate 12 can provide good stability. The triangular structure can disperse and balance the load, which enables the front support device to carry a heavier basket 23 and items. At the same time, due to its stability, the triangular structure can provide the required strength while using less material, which helps to reduce the weight of the bicycle.

[0026] like Figure 2 and Figure 3As shown, two square through holes are opened in the middle of the support plate 12, and a T-shaped groove is opened inside the support plate 12, and the T-shaped groove is located in the middle of the two square through holes, and a T-shaped stop block 22 is fixed to the lower end of the second support seat 21, and the T-shaped stop block 22 is adapted to the T-shaped groove. The T-shaped groove and the T-shaped stop block 22 can provide precise movement distance control, and the T-shaped structure provides good stability when subjected to vertical or horizontal forces.

[0027] Furthermore, threaded holes are provided at the bottom end of the second support seat 21 and on both sides of the T-shaped stop block 22 , and bolts 15 penetrate through the two square through holes, and the support plate 12 and the second support seat 21 are fixedly connected by the bolts 15 .

[0028] Furthermore, a second groove is formed at the upper end of the second support seat 21, and a third groove is formed at the upper end of the first support seat 20, and the second groove is the same size as the third groove, and the second groove and the basket 23 and the third groove and the basket 23 are adapted to each other. The second groove and the third groove can provide a stable support for the basket 23, reduce shaking on a bumpy road, and the basket 23 fixed in the second groove and the third groove greatly reduces the possibility of falling off during riding, increasing the safety of riding. At the same time, the design of the second groove and the third groove can reduce the damage to the basket 23 caused by improper fixing, and extend the service life of the basket 23.

[0029] like Figure 3 , Figure 5 and Figure 6 As shown, a first lock buckle 13 is provided at the lower end of the U-shaped frame 11, a limiting block 14 is fixed at the lower end of the U-shaped frame 11 and at the upper end of the first lock buckle 13, and two second lock buckles 24 are fixed at one end of the support plate 12 and close to the end of the vehicle body main frame 10. The two second lock buckles 24 are adapted to the first lock buckle 13, and the two second lock buckles 24 and the first lock buckle 13 can facilitate the placement of the lock body 26, reasonably utilize the space on the support plate 12, and have a neat appearance.

[0030] Furthermore, a lock body 26 is assembled on the upper end of the second lock buckle 24. When riding, the lock body 26 is locked to the second lock buckle 24. When the bicycle needs to be locked, the lock body 26 can be removed from the second lock buckle 24 and locked to the first lock buckle 13. At this time, the front wheel of the bicycle is locked to increase the additional anti-theft function.

[0031] It should be noted that a lock tongue assembly is installed inside the lock body 26, and lock rod holes are provided at both ends of the lock body 26, and the lock tongue assembly and the lock rod hole are adapted to each other. After the two ends of the U-shaped frame 11 are inserted into the lock rod hole, a lock can be formed (the appearance of the lock can refer to the existing U-shaped lock), and when the U-shaped frame 11 and the lock body 26 cooperate to form a lock, the lock can limit the front wheels of the vehicle, so that the vehicle has an anti-theft function.

[0032] The working principle of the utility model is:

[0033] The U-shaped frame 11 is fixed on the main frame 10 of the vehicle body. The limit block 14 can limit the U-shaped frame 11 to be fixed in a suitable position to avoid inconvenience in hole alignment. The support plate 12 is fixed on the U-shaped frame 11 and the main frame 10 of the vehicle body. The first support seat 20 is fixed on the support plate 12. When the vehicle basket 23 is installed, the T-shaped stop block 22 at the bottom end of the second support seat 21 can be moved by loosening the bolt 15. The T-shaped stop block 22 will move along the T-shaped groove. When the second support seat 21 is in a suitable position, tighten the bolt 15, place the vehicle basket 23 on the second groove and the third groove and fasten it with screws. At the same time, the fixing plate 25 at the upper end of the second support seat 21 and the vehicle basket 23 are fastened with screws. When it is necessary to lock the vehicle, the lock body 26 fixed on the second lock buckle 24 can be removed, and the lock body 26 can be fixed on the first lock buckle 13 to complete the locking of the vehicle.

[0034] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
