On the contrary, the embodiments of the present utility model include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0027] The following describes a bicycle brake handle according to an embodiment of the present utility model with reference to the drawings.

[0028] As Figures 1-4As shown in the figure, a bicycle brake handle according to an embodiment of the present utility model includes a handlebar 1, a positioning sleeve 2, a brake handle assembly 3, and a threaded fixing sleeve 4. Among them, the positioning sleeve 2 is arranged on the surface of the handlebar 1; the brake handle assembly 3 includes a handle grip frame 31, a through groove 32, a pressing assembly 33, and a traction assembly 34. Among them, the handle grip frame 31 is slidably connected to the surface of the positioning sleeve 2, the through groove 32 is opened on the surface of the handle grip frame 31, the pressing assembly 33 is arranged on the inner wall of the through groove 32, the traction assembly 34 is arranged inside the handle grip frame 31, one end of the traction assembly 34 penetrates outside the handle grip frame 31 and is slidably connected to the surface of the handle grip frame 31, the end of the traction assembly 34 that penetrates outside the handle grip frame 31 is connected to one end of the brake wire, and the other end of the traction assembly 34 is in contact with the end of the pressing assembly 33 that penetrates into the handle grip frame 31; the threaded fixing sleeve 4 is respectively threadedly connected to the surface of the handlebar 1, the surface of the positioning sleeve 2, and one end surface of the handle grip frame 31.

[0029] It should be noted that the handle grip frame 31 is made of metal material to improve the overall strength and extend the service life.

[0030] Specifically, when in use, first install the positioning sleeve 2 on the handlebar 1. After installation, then put the handle grip frame 31 on the outside of the positioning sleeve 2. After the handle grip frame 31 is installed, fix the positioning sleeve 2 and the handle grip frame 31 on the handlebar 1 through the threaded fixing sleeve 4. After fixing, connect one end of the brake wire to the end of the traction assembly 34 that penetrates outside the handle grip frame 31. After installation, squeeze the pressing assembly 33 in the direction of the inside of the handle grip frame 31. The pressing assembly 33 runs under force and synchronously triggers the operation of the traction assembly 34. The traction assembly 34 runs to synchronously pull one end of the brake wire to realize the braking operation.

[0031] The brake handle assembly 3 provided by this device significantly improves the durability compared with the traditional design, effectively avoids the damage caused by bumps, thus significantly extending the service life. At the same time, the connection structures such as the positioning sleeve 2 and the threaded fixing sleeve 4 are more optimized and easy to operate, providing a better use experience and effect for users.

[0032] In an embodiment of the present utility model, as Figure 2 shown, a positioning ring platform 11 is integrally formed on the surface of the handlebar 1, and a threaded portion 12 is integrally formed on the outside of the positioning ring platform 11; the positioning sleeve 2 includes a positioning cylinder 21 and a fastening nut 22. Among them, the positioning cylinder 21 is sleeved on the outside of the threaded portion 12 and is in contact connection with the surface of the positioning ring platform 11. The fastening nut 22 is threadedly connected to the outer surface of the threaded portion 12 and is in contact connection with the surface of the end of the positioning cylinder 21 away from the positioning ring platform 11. The outer diameter of the fastening nut 22 is smaller than the outer diameter of the positioning cylinder 21

[0033] It should be noted that at the positions corresponding to each other on the surface of the positioning ring platform 11 and the surface of the positioning sleeve 2 described in this embodiment, there are respectively a positioning groove (not shown in the figure) and a positioning boss (not shown in the figure). The positioning boss is slidably connected to the positioning groove and the inner wall. The setting of the positioning boss and the positioning groove ensures that the angle of the positioning sleeve 2 is fixed after installation, and the use effect is good.

[0034] It should also be noted that a connecting ring platform is provided at one end of the positioning sleeve 2 close to the positioning ring platform 11. The outer diameters of one end of the positioning ring platform 11, the connecting ring platform, and the handle sleeve holder 31 are the same, and external threads are provided on their surfaces. The threaded fixing sleeve 4 is respectively threadedly connected to the surface of the positioning ring platform 11, the surface of the connecting ring platform, and the surface of one end of the handle sleeve holder 31.

[0035] Specifically, the setting of the positioning ring platform 11 facilitates the limitation of the position and angle of the positioning sleeve 2. When the positioning sleeve 2 is sleeved outside the threaded portion 12 and abuts against the surface of the positioning ring platform 11, it means that the position of the positioning sleeve 2 is accurate. Then, screw on the fastening nut 22 to fix the positioning sleeve 2. Since the outer diameter of the fastening nut 22 is smaller than the outer diameter of the positioning sleeve 2, it does not prevent the handle sleeve holder 31 from being sleeved outside the positioning sleeve 2. To keep the installation angle of the handle sleeve holder 31 fixed, a positioning groove and a positioning boss are respectively provided at the positions corresponding to each other on the surface of the positioning ring platform 11 and the surface of the positioning sleeve 2. When installing the positioning sleeve 2, the positioning boss needs to be inserted into the positioning groove to achieve the angle fixation of the positioning sleeve 2. When the angle of the positioning sleeve 2 is fixed, the handle sleeve holder 31 is also fixed accordingly, and there is no need to adjust it, and the use effect is good.

[0036] In an embodiment of the present invention, as Figure 2 shown, the handle sleeve holder 31 is slidably connected to the surface of the positioning cylinder 21. At the positions corresponding to each other on the surface of the positioning cylinder 21 and the inner wall of the handle sleeve holder 31, a positioning key 211 and a positioning groove are respectively provided. The positioning key 211 is slidably connected to the inner wall of the positioning groove.

[0037] It should be noted that the positioning cylinder 21 described in this embodiment is used to achieve the quick positioning of the handle sleeve holder 31, without the need to adjust its angle, with simple operation and convenient installation.

[0038] Specifically, when in use, align the positioning groove on the handle sleeve holder 31 with the positioning key 211. After alignment, directly sleeve the handle sleeve holder 31 outside the positioning cylinder 21, without the need to adjust its angle, and the use effect is good.

[0039] In an embodiment of the present invention, as Figure 3As shown in the figure, the pressing assembly 33 includes a pressing block 331, a spring 332, and a conical extrusion seat 333. Among them, the pressing block 331 is horizontally slidably connected to the inner wall of the through groove 32, and a spring 332 is fixedly connected between the pressing block 331 and the inner wall of the through groove 32. The conical extrusion seat 333 is horizontally slidably connected to the inner wall of the handle sleeve holder 31 and is fixedly connected to one end of the pressing block 331.

[0040] It should be noted that in this embodiment, the through groove 32 is provided with an installation groove facilitating the horizontal sliding of the pressing block 331 and is connected to the inside of the handle sleeve holder 31.

[0041] It should also be noted that finger grooves are provided on the surface of the pressing block 331.

[0042] Specifically, further illustrate the structure and connection relationship of the pressing assembly 33. Squeeze the pressing block 331 into the inside of the handle sleeve holder 31. The movement of the pressing block 331 synchronously drives the movement of the conical extrusion seat 333 and squeezes the spring 332. The movement of the conical extrusion seat 333 contacts the inner wall of the conical groove 342 and synchronously squeezes the conical groove 342 to move to one side. Release the pressing block 331, and the pressing block 331 resets under the elastic force of the spring 332 and synchronously drives the conical extrusion seat 333 to separate from the conical groove 342.

[0043] In an embodiment of the present utility model, as Figure 3 shown, the traction assembly 34 includes a rectangular traction sliding seat 341, a conical groove 342, and a traction connection seat 343. Among them, the rectangular traction sliding seat 341 is horizontally slidably connected to the inner wall of the handle sleeve holder 31 and is located on one side of the conical extrusion seat 333. The conical groove 342 is opened on the surface of the rectangular traction sliding seat 341 and corresponds to the position of the conical extrusion seat 333. One end of the conical extrusion seat 333 is slidably connected to the inner wall of the conical groove 342 and is adapted to the external dimension of the inside of the conical groove 342. One end of the rectangular traction sliding seat 341 penetrates outside the handle sleeve holder 31, and a traction connection seat 343 is integrally formed. The traction connection seat 343 is connected to one end of the brake cable.

[0044] It should be noted that in this embodiment, the inner wall of the handle sleeve holder 31 is provided with a limiting groove (not shown in the figure) facilitating the horizontal sliding of the rectangular traction sliding seat 341, and the surface of the handle sleeve holder 31 is provided with a strip-shaped groove (not shown in the figure) facilitating the sliding of the traction connection seat 343.

[0045] Specifically, the structure and connection relationship of the further traction assembly 34 will be described. The conical extrusion seat 333 enters the interior of the conical groove 342 and is slidably connected to the inner wall of the conical groove 342. During the sliding connection process, the conical extrusion seat 333 synchronously extrudes the conical groove 342 to move to one side. The movement of the conical groove 342 synchronously drives the rectangular traction sliding seat 341 and the traction connection seat 343 to move. The movement of the traction connection seat 343 synchronously pulls one end of the brake wire to achieve the braking operation.

[0046] In an embodiment of the present utility model, as Figure 4 shown, a step portion 3431 is provided on the surface of the traction connection seat 343. A T-shaped card slot 3432 is provided on the surface of the step portion 3431. One end of the brake wire is clamped and fixed to the inner wall of the T-shaped card slot 3432. A fixing seat 3433 is provided on the top of the step portion 3431. The fixing seat 3433 is fixedly connected to the top of the step portion 3431 through a locking bolt 3434.

[0047] It should be noted that the outer dimensions of the T-shaped card slot 3432 described in this embodiment are adapted to the shape of the brake wire card head, and the depth of the T-shaped card slot 3432 is the same as the height of the brake wire card head.

[0048] Specifically, during use, loosen the locking bolt 3434, then remove the fixing seat 3433, and then place the brake wire card head into the T-shaped card slot 3432. Since the depth of the T-shaped card slot 3432 is the same as the height of the brake wire card head, when the fixing seat 3433 is covered, the fixing seat 3433 will limit the top of the brake wire card head to prevent it from flipping during use. By ensuring the stable installation position of the brake wire card head, the braking force is further ensured to be stable, and the use effect is good.
