Description
Technical field
The utility model belongs to Electrical Bicycle accessory field, and particularly a kind of battery-driven car is vertical latching device.
Background technology
battery-driven car is vertical latching device that battery-driven car is connected locking so that the connection latching device of rotation direction vertical with front fork of electric vehicle, the latching device of traditional electrical motor-car is first butterfly heronsbill (band M6 screw thread) to be pressed in standpipe of front fork, then pack into vertical, the parts such as aluminium lid, because of seat tube and standpipe of front fork shorter, after a complete set of steel bowl and steel ball are packed into, do not tighten with locknut and shut, just screw tension and compression by heronsbill nut and M6 screw association, to be pressed on vertical and a whole set of steel bowl on seat tube, though this structure is fairly simple, but there is potential safety hazard, in case the M6 screw is loose, thrust weakens or disappears, steering handle will rotate freely, uncontrollable front fork and front-wheel, driving turns to will get out of hand, the utmost point can cause traffic accidents.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of firm, safe battery-driven car of locking that connects vertical latching device.
The utility model solves its technical matters and takes following technical scheme to realize:
a kind of battery-driven car is vertical latching device, comprise vertical, vertical core gland, standpipe of front fork, vertical lock screw, case ring, its innovation is: also comprise vertical core pipe, the stock screw, the wedge nut, standpipe of front fork rotates and is installed in seat tube, vertical core pipe lower end is inserted in standpipe of front fork and fitted with the wedge nut, vertical core pipe upper end suit vertical, vertical gland is fitted in vertical core pipe top, stock screw upper end is lifted on vertical gland, the stock screw is connected threadably with the wedge nut, to be integrated vertical core pipe and vertical core gland locking.
And the vertical core pipe of described handle lower surface is wedge.
Advantage of the present utility model and good effect are:
1. this battery-driven car has been set up vertical latching device vertical core pipe, stock screw, wedge nut, connects locking function better, and safety is higher.
2. this battery-driven car is scientific and reasonable vertical the design of lockup equipment, and the advantage that has that the locking linkage function is good, safety is high etc. is a kind ofly to have the battery-driven car of higher innovation vertical latching device.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, by specific embodiment.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
a kind of battery-driven car is vertical latching device, comprise vertical 1, vertical core gland 2, standpipe of front fork 12, vertical lock screw 3, case ring 4, its innovation is: also comprise vertical core pipe 5, stock screw 6, wedge nut 13, standpipe of front fork rotates and is installed in seat tube 11, vertical core pipe lower end is inserted in standpipe of front fork and fitted with the wedge nut, vertical core pipe upper end suit vertical, vertical gland is fitted in vertical core pipe top, stock screw upper end is lifted on vertical gland, the stock screw is connected threadably with the wedge nut, to be integrated vertical core pipe and vertical core gland locking.The vertical core pipe of described handle lower surface is wedge.
This battery-driven car is the principle of work of vertical latching device:
Between vertical and front fork by vertical core is connected, the assembly connection relation is: standpipe of front fork rotates and is installed in seat tube, fit on steel ball group 17 between upper steel bowl, upper steel ball bowl seat by upper locknut 8, upper steel bowl 9, upper steel ball bowl seat 10, lower steel bowl 16, lower steel ball bowl seat 14.The lower steel ball group 15 of assembling between lower steel bowl, lower steel ball bowl seat.Vertical core pipe lower end is inserted in standpipe of front fork together with the wedge nut, and the degree of depth 〉=75mm is far longer than catch siding institute subject distance; Seven case rings and a locknut aluminium lid 7 are inserted in vertical core upper end, and topmost suit will be fastened on vertical lock screw vertical core pipe upper end standing stand and using again; Last rotational lock stock screw, the wedge nut is stressed along wedge inclined-plane, vertical core pipe lower end is slided, radial and axial both direction all will produce displacement, be subject to the extruding that stops of standpipe of front fork inwall due to radial motion, when screw-driving moment larger, the extrusion friction power of wedge nut and standpipe of front fork inwall is also larger, therefore vertical core pipe and standpipe of front fork just can be tightly locking, locking is integral.Under the locking of stock screw, the stock screw in compression transfers the pressure to vertical core gland on vertical to vertical core gland, thereby will be press fit into securely on vertical core pipe vertical in addition, makes standing, connecting vertical core pipe, standpipe of front fork tightr, more firm.Candy i catch gear can be converted into the screw-down torque of long spiro nail vertical thrust and expansion pressure and the friction force of wedge nut dexterously, steering handle is connected more firm, and driving turns to more safe and reliable.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
