Abstract
A ratchet elevating device comprises a housing and an arc holder cooperated with the housing. Guide grooves are arranged on two vertical sides of the surface of the housing. The guide grooves are provided with horizontal chutes. A hollow cavity is disposed in the housing, and a tooth block is placed in the hollow cavity. Wing surfaces of two wings of the arc holder are cooperated with the guide grooves and the arc holder slides along the guide grooves. The wing surface of each wing of the arc holder is equipped with a trapezoid positioning groove. A positioning shaft arranged on the tooth block passes through the horizontal chutes to be placed in the trapezoid positioning grooves. The top end of each trapezoid positioning groove is provided with a blind hole. When the tooth block fully extend out of the hollow cavity along the horizontal chutes, the positioning shaft is cooperated with the blind holes. When the arc holder is lifted along the guide grooves, the positioning shaft is separated from the blind holes to make the tooth block withdraw along the horizontal chutes. The ratchet elevating device, scientific in structure, ingenious in design and high in safety, is practical and reliable, and serves as a practical apparatus for production of folding bicycles and folding electric vehicles.
Description
Technical field
The present invention relates to bicycle part field, relate in particular to the supplementary structure of folding bicycle or electric motor bicycle with folding saddle bracing frame.
Background technology
Chinese patent ZL201010504401.2 discloses a kind of bicycle saddle lifting adjusting device, comprise bicycle saddle bracing frame, on described bicycle saddle bracing frame, be provided with a chute, there are a bicycle saddle fixedly tenon and chute bearing fit, in described chute, a side is provided with tooth rank, described saddle is fixedly provided with a movable rotor on tenon, is provided with an one way engagement sprocket and coordinates with tooth rank on described movable rotor.When bicycle saddle is when fixedly tenon moves to certain position downwards in chute, the one way engagement sprocket on movable rotor is placed in to the position with the engagement of tooth rank, thus the fixing tenon of fixed saddle, while preventing cycling, saddle is to sinking; When regulating saddle fixedly during the upper-lower position of tenon; the one way engagement sprocket of movable rotor is placed in to the position separated with tooth rank; twitch up and down saddle fixedly tenon arrive after correct position releasing activity rotor again; make the engagement of one way engagement sprocket and tooth rank and by saddle fixedly tenon fix, thereby realize the lifting of bicycle saddle; This patent is not good enough because controlling the saddle structural stability that fixedly tenon moves in chute, vibrations when cause is ridden, sometimes make the fixedly de-tooth of tenon glide, saddle is also taken advantage of a situation and is glided and fold along saddle bracing frame like this, thereby for the use of folded bicycle has brought potential safety hazard, thereby be necessary to be improved on this basis.
Summary of the invention

A kind of ratchet jacking system as above, it is characterized in that: on described housing, be provided with a screw, on described arch holder, be provided with slotted hole, described slotted hole is that the macropore other end is aperture by one end, described macropore is communicated with composition with aperture flute profile, the screw rod of a set of upper spring is connected and fixes with the screw on described housing through described macropore, and one end of described spring holds the nut head that described arch holder, the other end hold described screw rod; And form a kind of elastic reset structure.
A kind of ratchet jacking system as above, is characterized in that: the pulling buckle rope that aperture one side and one end of described slotted hole is provided with bulb coordinates.
A kind of ratchet jacking system as above, is characterized in that: the described pulling buckle rope other end arranges another bulb.By another bulb with peripheral hardware of the present invention but the pulling buckle arranging on the saddle capable of lifted pulling buckle device coordinating with the present invention be connected, shown in Figure 3.
The hole, blind position arranging on arch holder of the present invention, continuous state when move on described positioning groove according to the described fix shaft of change in its position on described trapezoidal positioning groove, and arrange after a flex point, for fixing described tooth piece; If do not add External Force Acting, described fix shaft is stabilized in this place, hole, blind position, can effectively avoid Vehicle Driving Cycle to retract because vibrations cause described tooth piece, and supported saddle sinks suddenly and the potential safety hazard brought.
Scientific structure of the present invention, design ingenious, high safety, practical reliable, for the production of folding bicycle and electric motor bicycle with folding provides a kind of practical equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the combination assumption diagram of Fig. 1.
Fig. 3 is that the present invention with structure shown in Fig. 1 is applied in the enforcement illustration on car body.
Fig. 4 is the folding car structure figure that structure embodiment illustrated in fig. 3 is installed.
The specific embodiment
Below in conjunction with accompanying drawing 1 to accompanying drawing 4, embodiments of the invention are described, but should be limited to following examples:
A kind of ratchet jacking system is provided, it comprises a housing 1 and an arch holder 2, and described housing 1 vertical both sides, surface are provided with guide groove 11, on described guide groove 11, are provided with horizontal concrete chute 12, in described housing 1, be provided with a hollow reservoir 13, in described hollow reservoir 13, be equipped with a tooth piece 3; The aerofoil of described arch holder 2 both wings coordinates with described guide groove 11 and slides along described guide groove 11, is provided with a trapezoidal positioning groove 21 on the aerofoil of described arch holder 2 both wings; The fix shaft 311 of the axis hole 31 interior settings on described tooth piece 3 is placed on described trapezoidal positioning groove 21 through described horizontal concrete chute 12, and the upper end of described trapezoidal positioning groove 21 is provided with hole 211, blind position; When described tooth piece 3 stretches out completely along described horizontal concrete chute 12 from described hollow reservoir 13 is interior, described fix shaft 311 matches with hole 211, described blind position, when described arch holder 2 is upwards mentioned along described guide groove 11, described fix shaft 311 departs from described blind hole 211, position and described tooth piece 3 is retracted along described horizontal concrete chute 12.
