Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a novel bicycle rim, including shaft 3 and wheel rim, the wheel rim is enclosed to close by fixed half wheel rim 1 and the activity half wheel rim 7 that two symmetries set up and forms, 3 outside solid fixed rings 2 that have cup jointed of shaft, 3 outside of shaft lie in solid fixed ring 2 one side cover and are equipped with the activity ring 8, gu fixed ring 2 is connected with fixed half wheel rim 1 through spoke 4, activity ring 8 passes through spoke 4 and is connected with activity half wheel rim 7, shaft 3 is close to the one end threaded connection of activity ring 8 and has fastening nut 301, wherein, when fixed half wheel rim 1 encloses into complete wheel rim with activity half wheel rim 7, activity ring 8 and solid fixed ring 2 are under fastening nut 301's effect, the butt is in the same place, setting through fastening nut 301, take place to break away from when preventing that activity half wheel rim 7 and fixed half wheel rim 1 from forming complete wheel rim.

Preferably, the two sides of the fixing ring 2 are provided with first connecting rods 10 fixedly connected to the end portions of the fixed half rims 1, the two sides of the movable ring 8 are provided with second connecting rods 9 fixedly connected to the movable half rims 7, wherein the first connecting rods 10 are abutted to the second connecting rods 9 when the movable half rims 7 and the fixed half rims 1 form a complete rim, so that the contact area between the fixed half rims 1 and the movable half rims 7 is increased, and the stability of the fixed half rims 1 and the movable half rims 7 after being abutted is improved.

Preferably, the middle part of the first connecting rod 10 is provided with a quick release device, the quick release device comprises a button 1001, the middle part of the first connecting rod 10 is provided with a button groove 1004, the middle part of the button 1001 is rotatably connected with the button groove 1004, one end of the bottom of the button 1001 is fixedly connected with a spring 1003, the other end is connected with a push rod 1002, the button groove 1004 is provided with a through hole in clearance fit with the push rod 1002, the second connecting rod 9 is provided with a positioning groove 901 in clamping connection with the end of the push rod 1002, wherein, under the action of the spring 1003, one side of the button 1001 located on the spring 1003 is always higher than the other side, thereby enabling the mandril 1002 to be always jacked in the positioning groove 901, reducing the relative movement of the first connecting rod 10 and the second connecting rod 9, when the first connecting rod 10 is separated from the second connecting rod 9, the tilted end of the button 1001 needs to be pressed down to separate the top rod 1002 from the positioning groove 901, and then the first connecting rod 10 can be separated from the second connecting rod 9; when the first connecting rod 10 abuts against the second connecting rod 9, the tilting end of the button 1001 needs to be pressed down, so that the ejector rod 1002 moves towards the first connecting rod 10, and interference of the ejector rod 1002 on the connection of the first connecting rod 10 and the second connecting rod 9 is reduced.

Preferably, four through grooves are uniformly distributed in the movable ring 8 along the circumference of the movable ring, and the wheel shaft 3 is fixedly connected with a sliding block 302 matched with the through grooves, wherein the sliding block 302 and the sliding grooves are arranged to play a role in guiding the movable ring 8, so that the movable half-rim 7 is matched with the fixed half-rim 1 at a correct angle, and meanwhile, the movable ring 8 can be prevented from rotating.

Preferably, T type spout 5 has all been seted up to the both sides that fixed semi-rim 1 and activity semi-rim 7 are close to the junction, and sliding connection has T type slider 6 in T type spout 5, and wherein, during the use, slide T type slider 6 to the middle part of fixed semi-rim 1 and activity semi-rim 7 to reduce and produce axial shake between fixed semi-rim 1 and the activity semi-rim 7.

Preferably, the fastening nut 301 is a locknut, wherein the locknut can reduce the occurrence of looseness, thereby ensuring the stability of the movable half-rim 7 after being butted with the fixed half-rim 1.

One specific application of this embodiment is:

when the rim needs to be folded, firstly, the T-shaped sliding block 6 slides to one side of the sliding groove, then the fastening nut 301 on the wheel shaft 3 is detached, finally, the button 1001 is pressed down to enable the end part of the ejector rod 1002 to leave the positioning groove 901, then the movable ring 8 moves towards the direction far away from the fixed ring 2, and then the movable half rim 7 is rotated by 180 degrees and can be overlapped with the fixed half rim 1; when the movable half rim 7 and the fixed half rim 1 need to be butted, firstly, the movable half rim 7 is rotated by 180 degrees, then the sliding blocks 302 correspond to the sliding grooves one by one, the movable half rim 7 is pushed to the fixed half rim 1, the sliding grooves are matched with the sliding blocks 302, at the moment, the push buttons 1001 need to be pressed, the push rods 1002 move towards the first connecting rods 10, so that the interference between the first connecting rods 10 and the second connecting rods 9 is reduced, then, the fastening nuts 301 are used for locking and fixing, and finally, the T-shaped sliding blocks 6 are moved to the middle of the connecting positions of the movable half rim 7 and the fixed half rim 1; the occupied area of the rim can be reduced through the structure, the packaging volume of the rim is reduced, and the rim is convenient to transport.

In conclusion, the fastening nut 301 can fix the movable half rim 7 and the fixed half rim 1 after being connected, and the contact area between the movable half rim 7 and the fixed half rim 1 after being connected can be increased by arranging the first connecting rod 10 and the second connecting rod 9, so that the stability is improved, and the radial shaking of the movable half rim 7 and the fixed half rim 1 after being connected can be reduced by arranging the T-shaped sliding block 6 and the T-shaped sliding groove 5.
