Description

There is the cycle frame of integral type lockset

Technical field

The invention belongs to bicycle assembly parts technical field, particularly relate to a kind of cycle frame with integral type lockset.

Background technology

In modern society, bicycle has become one of vehicle of indispensability when people go on a journey.Along with the increase of bicycle recoverable amount, the antitheft problem of bicycle highlights gradually, also becomes one of subject matter considered when people purchase bicycle.Existing bicycle generally dispatches from the factory and does not arrange lockset, and lock needs to purchase in addition and install, and this brings inconvenience for people.And the lockset that the later stage purchases installation is installed owing to adopting the fasteners such as bolt and car body, anti-orcible entry effect is poor.

Summary of the invention

The present invention provides a kind of cycle frame with integral type lockset for solving in known technology the technical matters that exists, solves the trouble that people purchase and installed individual lock the later stage, promotes the anti-orcible entry ability of lockset simultaneously.

The technical scheme that the present invention takes for the technical matters existed in solution known technology is: the cycle frame with integral type lockset comprises front cross rail, front cant beam, chain stay, seat pipe and vertical fork, the rear end of front cross rail and the upper end of vertical fork are all connected with the upper end of seat pipe is affixed, and the lower end of front cant beam and seat pipe and the front end of chain stay are converged and be fixed in bottom bracket axle; Present pipe is provided with lockset; Lockset comprise grafting be fixed in be opened in a pipe bottom, sleeve in radial through mounting hole, rotating shaft is provided with in sleeve, also comprise first body of rod and second body of rod, both lower ends are articulated and connected at the two ends of rotating shaft respectively, the axis of its jointed shaft all with the central axis of rotating shaft; Offer accommodating groove on the top of the first body of rod inwall, be hingedly connected with the 3rd body of rod at the top of accommodating groove inner chamber, be connected with dead bolt in the end of the 3rd body of rod; Lock core is installed the upper end of second body of rod is affixed; The also compressing groove had for holding first body of rod, second body of rod and lock core on the sidewall of present pipe.

Advantage of the present invention and good effect are: the cycle frame with integral type lockset that the invention provides a kind of structure design advantages of simple, compared with existing vehicle frame and free-standing lock device, the technical program by arranging the lockset be made up of sleeve, rotating shaft, first body of rod, second body of rod, foldable dead bolt and lock core on the seat pipe of vehicle frame, achieve configuring with car of lockset, solve people and purchase and install the trouble that free-standing lockset brings the later stage, also can effectively prevent lockset from losing.Above-mentioned lockset has compact conformation, feature that structural strength is large, by being integrated by the seat duct ligation of lockset and vehicle frame, improves the ability of the anti-orcible entry of lockset, and then improves the theftproof performance of bicycle.During car locking, only first body of rod and second body of rod need be transferred to by the groove at respective place, sealed in the docking of rear wheel place after the certain angle that verts, simple operation; After unblock, in lockset retraction groove, do not affect the attractive in appearance of car body, do not affect the comfort level of riding yet.

Preferably: the upper end of present pipe is also provided with the fastener for being fixed the saddle pipe inserted in seat pipe.

Preferably: the line of centers of rotating shaft and the centerline parallel of bottom bracket axle are arranged.

Detailed description of the invention

For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:

Refer to Fig. 1, the present invention includes front cross rail 1, front cant beam 2, chain stay 4, seat pipe 6 and vertical fork 8.Wherein, the rear end of front cross rail 1 and the upper end of vertical fork 8 are all connected with the upper end of seat pipe 6 is affixed, and the lower end of front cant beam 2 and seat pipe 6 and the front end of chain stay 4 are converged and be fixed in bottom bracket axle 3.

Present pipe 6 is provided with lockset 7.

As shown in Figure 2, lockset 7 comprise grafting be fixed in be opened in a pipe 6 bottom, sleeve 7-8 in radial through mounting hole, in sleeve 7-8, be provided with rotating shaft 7-3.Also comprise the first body of rod 7-2 and the second body of rod 7-7, both lower ends are articulated and connected at the two ends of rotating shaft 7-3 respectively, the axis of its jointed shaft all with the central axis of rotating shaft 7-3.Offer accommodating groove 7-1 on the top of the first body of rod 7-2 inwall, be hingedly connected with the 3rd body of rod 7-4 at the top of accommodating groove 7-1 inner chamber, be connected with dead bolt 7-6 in the end of the 3rd body of rod 7-4.By stirring the 3rd body of rod 7-4, realize dead bolt 7-6 complete folding storage or completely protruding in accommodating groove 7-1.Affixed in the upper end of the second body of rod 7-7 lock core 7-5 coordinated with dead bolt 7-6 is installed.
