Detailed Description

The present invention will be further explained with reference to the accompanying drawings and embodiments:

please refer to fig. 1-8, the utility model discloses a moped with quick detachable back, including front wheel support 1, rear wheel support 2 and back 3, front wheel support 1 and rear wheel support 2 pass through connecting piece 4 to be connected, front wheel support 1 articulates on connecting piece 4, back 3 is installed on connecting piece 4 and is located the outside of rear wheel support 2, the both ends of back 3 are connected and are equipped with mounting 5, the one end that connecting piece 4 is close to mounting 5 is equipped with convex body 6, be equipped with on mounting 5 with convex body 6 assorted spout 7, one side that convex body 6 was kept away from to spout 7 is equipped with the release assembly 9 that is used for dismantling mounting 5 from connecting piece 4.

Be equipped with the vallecular cavity 8 that is used for accomodating separator assembly 9 between the both sides terminal surface of mounting 5, vallecular cavity 8 is linked together with spout 7.

As shown in fig. 6-7, the separating assembly 9 includes a cap nut 91 and a lock 92 in threaded connection with the cap nut 91, the lock 92 includes a connecting rod 93 connected with the cap nut 91 and a locking head 94 vertically connected with the end of the connecting rod 93, and the locking head 94 abuts against the inner wall of the cavity 8 and is provided with a return spring 95. The end surface of the convex body 6 close to the fixed piece 5 is provided with a locking groove 10 for sliding the locking head 94.

When the locking head 94 is located in the locking groove 10, the return spring 95 is in an extended state, that is, the upper end and the lower end of the locking head 94 are pressed against the inner wall of the locking groove 10, and at this time, the fixing member 5 cannot slide out from the convex body 6 along the sliding groove 7; when the locking head 94 is completely withdrawn from the locking groove 10, the return spring 95 is in a compressed state, that is, the locking head 94 is not pressed against the locking groove 10, and at this time, the fixing member 5 can slide out from the protrusion 6 along the sliding groove 7, so that the fixing member 5 can be detached from the connecting member 4. Through connecting rod 93 and cover type nut 91 to at locking head 94 and 8 inner walls fixedly connected with reset spring 95 of vallecular cavity, can through pressing and unclamping cover type nut 91, realize withdrawing from locking head 94 or stop in locked groove 10, and then realize the quick dismantlement or the installation of back.
