[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] like Figures 1 to 8 As shown.

[0037] A bicycle carrier includes a base frame 1, a first wheel clamp 2 movably connected to the base frame 1, and a limiting and fixing device 3 movably connected at both ends to the base frame 1 and the first wheel clamp 2, respectively. The limiting and fixing device 3 consists of a sleeve cavity 31 movably connected at one end to the first wheel clamp 2, a helical toothed rod cavity 32 with one end extending into the sleeve cavity 31 and the other end movably connected to the base frame 1, and a locking device 33 disposed on the sleeve cavity 31. The helical toothed rod cavity 32 is provided with helical teeth 321. The locking device 33 can limit the distance of the helical toothed rod cavity 32 extending into the sleeve cavity 31 by engaging with the helical teeth 321. The locking device 33 includes a lock box 331 disposed on the sleeve cavity 31, a lock handle 332 rotatably connected to the lock box 331, and a lock tongue 333 disposed on the lock handle 332. The lock box 331 is provided with a locking hole 334 for the lock tongue 333 to pass through and engage with the helical teeth 321.

[0038] First, fix the bicycle rack to the car's rear rack or roof crossbar. When you need to carry the bicycle, place the bicycle 9 on the base frame 1, bringing the first wheel clamp 2 close to the wheel of the bicycle 9, and simultaneously press the limiting and fixing device 3. Under the pressure of the first wheel clamp 2, the helical toothed cavity 32 and the helical teeth 321 gradually extend into the sleeve cavity 31. After the first wheel clamp 2 clamps the wheel of the bicycle 9, engage the locking handle 332 of the locking device 33 onto the lock box 331. At this time, driven by the locking handle 332, the locking tongue 333 passes through the engaging hole 334 and engages with the helical teeth 321 on the helical toothed cavity 32, thus fixing the bicycle 9. To prevent the bicycle 9 from being stolen when the vehicle is parked, an anti-theft lock can be installed on the fixing device 3. After the anti-theft lock is locked, the locking handle 332 cannot be lifted, and the bicycle 9 will always be in a fixed and anti-theft state.

[0039] When the bicycle needs to be removed, lift the locking handle 332 to separate the locking tongue 333 from the helical tooth 321, move the first wheel clamp 2 away from the wheel of the bicycle 9, and at the same time, the limiting and fixing device 3 loses pressure, and the helical tooth cavity 32 gradually extends out of the sleeve cavity 31. The bicycle 9 can then be removed from the base frame 1.

[0040] The first wheel clamp 2 is provided with a wheel fixing device 5. The wheel fixing device 5 consists of a first locking member 51 and a second locking member 52 that can be snapped together with the first locking member 51. The first locking member 51 is provided with a drive hole 511 and a first clamping part 512. The second locking member 52 is provided with a horizontal sliding hole 521. A spring and a horizontally sliding top rod 53 connected to one end of the spring are provided in the horizontal sliding hole 521. The top rod 53 is provided with a drive part 531 that can pass through the drive hole 511. The second locking member 52 is provided with a second clamping part 522 that can form a clamping hole 54 with the first clamping part 512. The first locking member 51 is provided with a first wheel contact part 513. The second locking member 52 is provided with a second wheel contact part 523 that can form a wheel contact groove 55 with the first wheel contact part 513.

[0041] The wheel fixing device 5 on the first wheel clamp 2 can better fix the wheel of the bicycle 9 and prevent the bicycle 9 from wobbling up and down during vehicle operation. It can also be used in conjunction with the first wheel clamp 2 to fix wheels of different sizes. After the first locking member 51 and the second locking member 52 are engaged, the first wheel clamp 2 is held by the clamping hole 54 formed by the first clamping part 512 and the second clamping part 522, and can slide up and down along the first wheel clamp 2. To fix the wheel, the drive part 531 passing through the drive hole 511 is moved, which drives the top clamping rod 53 away from the first wheel clamp 2 in the horizontal sliding hole 521 and compresses the spring set in the horizontal sliding hole 521. The position of the fixing device 5 on the first wheel clamp 2 is adjusted according to the size of the wheel. The drive part 531 is released, and under the elastic force of the spring, the top clamping rod 53 presses against the first wheel clamp 2, and the position of the fixing device 5 is fixed. The wheel is clamped by the first wheel clamp 2, and simultaneously, the wheel contact groove 55 formed by the first wheel contact portion 513 and the second wheel contact portion 523 on the fixing device 5 presses against the wheel, preventing the bicycle 9 from wobbling up and down when the vehicle is in motion. A tightening hole can also be provided on the first wheel clamp 2, into which a tightening rod 53 can extend to increase the firmness. The spring provided in the horizontal sliding hole 521 is not shown in the attached drawings.

[0042] To release the wheel, lift the latch handle 332 of the locking device 33 to separate the latch 333 from the helical tooth 321, move the first wheel clamp 2 away from the wheel of the bicycle 9, and at the same time move the fixing device 5 away from the wheel.

[0043] The first wheel clamp 2 has a U-shaped structure, and there are two of each of the following: the drive hole 511, the first clamping part 512, the second clamping part 522, the top clamping rod 53, and the drive part 531. The two top clamping rods 53 can respectively abut against the two rods of the U-shaped structure, better securing the wheel. The spring between the two top clamping rods 53 is not shown in the attached drawing.

[0044] A second wheel clamp 4 is provided on the base frame 1 at the end away from the first wheel clamp 2, and the second wheel clamp 4 is movably connected to the base frame 1. The second wheel clamp 4 is provided to fix the other wheel of the bicycle 9. The wheel fixing device 5 can also be provided on the second wheel clamp 4 to press down the other wheel of the bicycle 9.

[0045] Gas springs 34 are installed in the sleeve cavity 31 and the helical toothed rod cavity 32. When the first wheel clamp 2 approaches the wheel of the bicycle 9 and simultaneously squeezes the limiting and fixing device 3, the helical toothed rod cavity 32 gradually extends into the sleeve cavity 31, compressing the gas spring 34. At this time, the gas spring 34 exerts an outward force on the sleeve cavity 31 and the helical toothed rod cavity 32, making the locking tongue 333 more securely engaged with the helical tooth 321. When it is necessary to remove the bicycle 9, the locking handle 332 is lifted, causing the locking tongue 333 to separate from the helical tooth 321. At this time, the outward force exerted by the gas spring 34 on the sleeve cavity 31 and the helical toothed rod cavity 32 is released, causing the helical toothed rod cavity 32 to gradually extend out of the sleeve cavity 31 and move the first wheel clamp 2 away from the wheel of the bicycle 9, allowing the bicycle 9 to be removed from the base frame 1. The gas spring 34 is a universal accessory and can be purchased on the market.

[0046] The base frame 1 has a U-shaped base plate 6 on its bottom surface. An inverted triangular limiting block 7 is provided at one end of the first wheel clamp 2 that connects to the base frame 1. The base frame 1, the limiting block 7, and the U-shaped base plate 6 are connected by bolts. The limiting block 7 has a first limiting surface 71 and a second limiting surface 72 on its left and right sides. When the first wheel clamp 2 is opened, the first limiting surface 71 on one side of the limiting block 7 contacts the surface of the U-shaped base plate 6, preventing the first wheel clamp 2 from having an excessive angle with the base frame 1, which could cause damage to the limiting and fixing device 3 due to prolonged stress. When stored, the first wheel clamp 2 is closed, at which point the second limiting surface 72 on the other side of the limiting block 7 contacts the surface of the U-shaped base plate 6, making the first wheel clamp 2 parallel to the base frame 1, preventing a negative angle that could cause damage to the limiting and fixing device 3 due to prolonged stress. An inverted triangular limiting block 7 and a U-shaped base plate 6 can also be provided at the same position where the second wheel clamp 4 connects to the base frame 1.

[0047] The base frame 1 is provided with a V-shaped wheel groove 11, and a wheel limiting member 8 is provided in the V-shaped wheel groove 11. The V-shaped wheel groove 11 makes the bicycle 9 more stable. There can be two wheel limiting members 8, one placed behind the front wheel and one placed in front of the rear wheel, to further prevent the bicycle 9 from moving back and forth during vehicle operation.

[0048] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any changes, modifications, substitutions, and variations made to the above embodiments based on the essential technical content of the present invention shall still fall within the scope of the technical solution of the present invention.
