Description

Closed bicycle frame folding unit

Technical field

The utility model closed bicycle frame folding unit, what relate to is bicycle designs manufacturing technology field, particularly Folding Bicycle technical field.

Background technology

Comprehensive bicycle frame folder both at home and abroad, thumping majority is all used theory of machines, reach the purpose of locking, be line contact locking, its self-lock force exposes with cam face, not attractive in appearance, the cam precision of manufacturing is not high, and coupling mechanism force is little, and unreliable, the rider often will clamp or unclamp folder with very big torsion, this uses very inconvenient concerning women or the elderly and weak rider; At this moment, as the Uneven road of riding, shake frequently relatively, it often loses self-lock ability, can't carry out self-locking, the very easy generation that causes personal injury accidents is so it often adopts double insurance, subsidiary ... the cover latch mechanism, mechanism's relative complex has increased productive costs, and uneconomical.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned defective, design a kind of both attractive in appearance, light weight, the closed bicycle frame folding unit that tightening is quick, firm.Its technology is achieved in that the structure that comprises handwheel, holding screw, spring device, axle sleeve, hinge, cover plate, flathead screw, it is characterized in that: be fixed on the hook axle of right body and be with latch hook, one side is provided with by goalpost, steel ball, stage clip, the spring device formed of screw silently, latch hook is provided with the crotch that can hook lock shaft, the left body of latch hook one side, be fixed with cover plate, block set by flathead screw, be provided with the screw mandrel that has handwheel in the block set, left side body and right body junction are the inclined-plane, by the active connection of the hinge in the axle sleeve.The positive effect of implementing after this technology is: broken through the old design philosophy of domestic and international bicycle trade, with interior envelope spiral catch gear, reached light locking, little power is unclamped catch gear, reach the purpose that stretches Foldable frame, handsome in appearance, compact conformation adopts spiral to pay locking, screw thread is easily made, the precision height, self-lock force is big, reliable lock, and the torsion that folder is grown, locks and unclamped to the life-span is little, be the regeneration product of Folding Bicycle, be subjected to women and the elderly's weakling's welcome deeply.

Description of drawings

Fig. 1 locks timer-operated sectional structure scheme drawing for the utility model,

Wherein, 1-handwheel, 2-holding screw, 3-spring device, 4-hook axle, 5-latch hook, the right body of 6-, 7-axle sleeve, 8-hinge, 9-left side body, 10-lock shaft, 11-screw mandrel, 12-block set, 13-cover plate, 14-flathead screw;

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:

See accompanying drawing 1, be fixed on the hook axle (4) of right body (6) and be with latch hook (5), one side is provided with by goalpost, steel ball, stage clip, the spring device (3) formed of screw silently, latch hook (5) is provided with the crotch that can hook lock shaft (10), the left body (9) of latch hook (5) one sides, by flathead screw (14) securing cover plate (13), block set (12), be provided with the screw mandrel (11) that has handwheel (1) in the block set (12), holding screw (2) is fixed on screw mandrel (11) top with handwheel (1), left side body (9) is the inclined-plane with right body (6) junction, by the active connection of hinge (8) in the axle sleeve (7), vehicle frame links into an integrated entity respectively by left body (9) and right body (6) two ends.

See accompanying drawing 1, for locking timer-operated sectional structure, when needs during with bicycle folding, rotation hand wheel (1) unclamps screw mandrel (11), and screw mandrel (11) top sphere breaks away from latch hook (5), left side body (9) and right body (6) rotate around hinge (8), left side body (9) separates with the junction that right body (6) is the inclined-plane, and the front and rear wheel of bicycle and relevant parts are folded, and are convenient to collection.When the need locking is used, left side body (9) and right body (6) rotate around hinge (8), left side body (9) is the junction, inclined-plane with right body (6) and combines, and latch hook (5) hooks lock shaft (10), rotation hand wheel (1), screw mandrel (11) advances to latch hook (5) direction, screw mandrel (11) top sphere contact latch hook (5), spring device (3) location screws locking again, make bicycle enter running condition, ride usefulness for the user.
