Description

Technical Field

[0001] This utility model relates to the field of bicycle handlebar technology, specifically to a bicycle handlebar structure. Background Technology

[0002] The bicycle handlebars have a relatively complex and sophisticated structure. They are not only a key component for riders to control direction, but also carry multiple functions such as braking and shifting.

[0003] Bicycle handlebars are consumable parts because they are easily damaged when a bicycle falls over and hits the ground. However, current bicycle handlebars do not have a disassembly function. When bicycle handlebars are damaged by impact, if they cannot be easily disassembled, riders often need to seek professional repair services or replace them themselves using complicated tools. This is not only time-consuming and laborious, but may also increase additional repair costs. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a bicycle handlebar structure.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A bicycle handlebar structure, comprising:

[0007] Handlebars;

[0008] Both fixing rods are fixed to the handlebar frame;

[0009] Two handles are respectively installed at the ends of the two fixed rods that are far apart from each other, and each handle is fixed with a plug rod;

[0010] Two slots are respectively provided at the ends of the two fixing rods that are far apart from each other;

[0011] Two mounting structures are provided, and both grips are connected to corresponding fixed rods via the mounting structures.

[0012] As a further embodiment of this utility model: the mounting structure includes:

[0013] Both openings are formed on the fixed rod, and both openings are connected to the slot;

[0014] Two positioning springs are fixed inside the two openings respectively;

[0015] A sliding sleeve is fitted onto the fixed rod.

[0016] Both protrusions are fixed on the inner ring of the sliding sleeve;

[0017] Both slots are provided on the insert rod;

[0018] A retaining ring is fixedly sleeved on the retaining rod;

[0019] The spring has one end connected to the fixed ring and the other end connected to the sliding sleeve.

[0020] As a further embodiment of this invention, the outer surface of the insertion rod is in contact with the groove wall of the slot.

[0021] As a further aspect of this utility model: the shape of the positioning spring is adapted to the shape of the slot.

[0022] As a further embodiment of this invention, the protrusion has a hemispherical structure.

[0023] As a further embodiment of this utility model: the handlebar frame is provided with a ventilation opening, the fixing rod, the grip and the insert rod are all provided with air ducts, and the outer surface of the grip is provided with a plurality of air outlets, each of which is connected to the air duct inside the grip.

[0024] The beneficial effects of this utility model are:

[0025] 1. This bicycle handlebar structure enables quick installation and removal of the handlebars through its installation mechanism. During installation, the sliding sleeve is pulled to separate the protrusion from the positioning spring, allowing the insert rod to be inserted into the slot and secured. After releasing the sliding sleeve, the protrusion presses against the positioning spring, causing it to snap into the slot and complete the fixation. During removal, the sliding sleeve is pulled to restore the positioning spring to its original shape and disengage it from the slot, allowing the insert rod to slide out easily. This design not only simplifies the installation and removal process but also greatly improves work efficiency, making it convenient for staff to quickly replace damaged handlebars.

[0026] 2. The ventilation openings on the handlebars and the air duct design on the fixing bar, grip, and insert bar allow air to smoothly enter and flow through the grip during riding, and finally be blown out through several air outlets on the outer surface of the grip. In summer riding, the air blown out by these air outlets can effectively reduce the temperature of the rider's hands and prevent sweating due to prolonged gripping of the grip, thereby improving riding comfort. In addition, by adding a coverable design, the cover can be closed over the ventilation openings in winter to prevent cold air from entering the grip, further enhancing the practicality and flexibility of the structure.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figure 1-3 As shown, a bicycle handlebar structure includes a handlebar frame 1; two fixing rods 2, both fixed to the handlebar frame 1; two grips 3, respectively installed at the ends of the two fixing rods 2 that are far apart from each other, and each grip 3 is fixed with a plug rod; and two slots 4, respectively opened at the ends of the two fixing rods 2 that are far apart from each other, with the outer surface of the plug rod and the groove wall of the slot 4 fitting together.

[0034] The handle structure also includes two mounting structures. Both grips 3 are connected to the corresponding fixed rods 2 through the mounting structures. The mounting structures include: two openings 51, both of which are opened on the fixed rods 2 and are connected to the slots 4; two positioning springs 52, which are fixed in the two openings 51 respectively; a sliding sleeve 53, which is provided on the fixed rods 2; two protrusions 54, which are fixed on the inner ring of the sliding sleeves 53 and are hemispherical; two slots 55, which are opened on the insert rods and whose shapes match the shapes of the positioning springs 52; a fixing ring 56, which is fixedly sleeved on the fixed rods 2; and a spring 57, one end of which is connected to the fixing ring 56 and the other end of which is connected to the sliding sleeve 53.

[0035] The handlebar frame 1 has ventilation openings 6, and the fixing rod 2, grip 3 and insert rod all have air ducts. The outer surface of the grip 3 has several air outlets, each of which is connected to the air duct inside the grip 3.

[0036] The working principle of this utility model:

[0037] In use, the bicycle handlebar structure proposed in this utility model involves mounting the handlebar 3 onto the fixed rod 2 via an installation structure. When installing the handlebar 3, the operator first pulls the sliding sleeve 53, bringing it closer to the fixed ring 56. As the sliding sleeve 53 moves, it moves the two protrusions 54 until they separate from the two positioning springs 52. Without the pressure of the two protrusions 54, the two positioning springs 52 return to their original shape and retract into the two openings 51. Next, the operator inserts the rod on the handlebar 3 into the slot 4. Two guide blocks are fixed on the rod, and two guide grooves are provided in the slot 4. The operator aligns the two guide blocks with the two guide grooves and inserts the rod into the slot 4. When the rod is fully inserted into the slot 4, the two locking slots 55 are precisely aligned with the two positioning springs 52. Then, the operator releases the sliding sleeve 53, allowing it to be released under the elastic force of the spring 57. The sliding sleeve 53 is moved to the position facing the two openings 51. At this time, the two protrusions 54 will squeeze the two positioning springs 52, causing the two positioning springs 52 to deform. When the two positioning springs 52 are deformed, they will be inserted into the two slots 55 respectively. At this time, the two positioning springs 52 and the two slots 55 fix the rod and the position of the handle 3 will also be fixed. This realizes the quick installation of the handle 3. When disassembling the handle 3, the operator also pulls the sliding sleeve 53 to separate the two protrusions 54 from the two positioning springs 52, and then restores the two positioning springs 52 to their original state. In this case, the two positioning springs 52 will disengage from the two slots 55. Without the restriction of the two positioning springs 52, the rod can slide out from the slot 4, thus realizing the quick disassembly of the handle 3. This quick disassembly and assembly mechanism makes it convenient for the operator to replace the handle 3 when it is damaged.

[0038] In addition, the handlebar frame 1 has ventilation openings 6, and the fixing rod 2, grips 3 and insert rods all have air ducts. The outer surface of the grips 3 has several air outlets, each of which is connected to the air duct inside the grips 3. During the ride, air enters the ventilation openings 6 and then enters the two grips 3 through the air ducts, and finally blows out through the air outlets. In summer, the air blown out by the air outlets can cool the rider's hands, preventing the rider's hands from sweating when holding the grips 3 and improving riding comfort. Furthermore, a cover plate can be added to the handlebar frame 1 facing the ventilation openings 6. In winter, the handlebar cover plate can be closed over the ventilation openings 6.

[0039] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
