Description
Technical Field
The utility model relates to a high folding mechanism of security and use its equipment belongs to the sport equipment field.
Background
Chinese patent (publication No. CN 201193075) discloses a double-locking bicycle folder, belonging to the technical field of sports equipment. Including the last folder that is used for connecting, lower folder, its characterized in that goes up folder one side and the articulated cooperation of folder down, the opposite side sets up the frid of taking the spout, set up between two frids with spout sliding fit's locking axle, locking epaxial coaxial coupling rather than normal running fit's locking hook, quick detach handle, locking hook and the lower folder go up the latch hook lock joint cooperation that corresponds the setting, quick detach handle is through the oval cam and the last folder press-contact cooperation that the lower part set up. The folder has the advantages of simple and compact structure, double locking functions, high folding speed, safe and reliable performance, convenience in installation and maintenance and low production cost.
The utility model provides a two locking bicycle scray, its quick detach handle passes through the elliptical cam that the lower part set up and the cooperation of last folder pressure contact, can satisfy from the locking surface to the face of opening position change that the big curvature radius increase and decrease more than 90 degrees of bottom dead center promptly to drive locking hook and fold body flash time quick locking from top to bottom, realize the purpose of main locking.
Above-mentioned scheme, whole beta structure's rotation moment of torsion and deformation force need be born by the locking hook, but are subject to current manufacturing material and size restriction, and the locking hook hardly satisfies its structural strength requirement, easily takes place the locking hook and warp, and cracked risk even leads to the unable reliable locking of upper and lower folded body, has the potential safety hazard.
Further, when the folding body needs to be folded about this scheme, need break off the quick detach handle with the fingers and thumb earlier, then the effort through the quick detach handle drives the locking hook and will fold the body from top to bottom and unblock fast when flash. But the quick detach handle is more protruding, very easily bumps by mistake, and after the quick detach handle was touched by the mistake, took place the position change back, the main locking of locking hook was relieved, because the locking hook need bear whole beta structure's the turning force and the power of warp, only relies on the vice locking of torsional spring, and the locking hook unhook very easily for upper and lower folder takes place relative rotation, has the potential safety hazard.
