Description

A kind of rotary tiltable operation with the car pump-up device

The utility model relate to a kind of can with bicycle, three-wheel vehicle and Electrical Bicycle constitute with the body car with the car pump-up device, refer more particularly to a kind of have last fitting and following connecting element with the car pump-up device.

Usually in sub by bike road, find that just car does not have gas; Sometimes do not have gas especially in summer once the car of going out morning, because the valve skin is aging, car often leaks gas, and this thing takes place, and at first is to delay the work hours, secondly is the Tire ﹠ Tube that damages bicycle.Existing a kind of patent No. is 972228454 dual-purpose Floor Pump, can address the above problem, but also there is following problem in it:

1. owing to the side of Floor Pump, be easy to be broken or fall bad at back seat;

2. because handle for flexibly connecting, is not durable the manufacturing cost height;

3. breather pipe is oversize, and Floor Pump need be pacified check valve;

4. the operating position of handle is higher.

The purpose of this utility model is: use inexpensive failure-free attaching parts, portablely take Floor Pump and bicycle links up commercial, realize carrying with car, energy instantaneously changing valve skin and inflation are difficult for losing, the firmly operation of being more convenient for, prevent that Floor Pump from being broken or breaking, and reaches inexpensive.

The purpose of this utility model is achieved in that with the car pump-up device and mainly is made of the standpipe on the vehicle frame and chain stay, Floor Pump, upper connector and following connecting element that upper connector comprises the eccentric wheel locking piece, can change locking lever and chuck bar.Can change locking lever and the chuck bar is inserted in standpipe and Floor Pump respectively, and constitute two garden post pairs; Couple together and constituted a ball pin and arrive changeing locking lever and chuck bar by the eccentric wheel locking piece, following connecting element the bottom of Floor Pump is fixed on the chain stay or under, constitute a spherical pair between Floor Pump and the chain stay, thereby, by vehicle frame, Floor Pump, can change locking lever and chuck bar and form four-bar linkage, make Floor Pump can rotate to the left side or the inboard of bicycle when the eccentric wheel locking piece unclamps, Floor Pump is between standpipe and back mud watt at ordinary times.By mobile upper connector, select suitable angle of inclination or cone angle, cooperate with suitable angle of rotation, when hand-held handle is operated up and down, can not hit saddle.

Handle is provided with one and stores the hole, is used to deposit the valve skin, but is convenient to instantaneously changing in the way.

The changeed locking lever of upper connector of the present utility model and chuck bar, and following connecting element, all available thin-walled iron-sheet stamped, production efficiency height, cost is low, for changeing the also method of available casting of tight locking bar and chuck bar, production efficiency height, handle is that hinge-less connects, and is not perishable, durable; Because the Floor Pump present position is lower, and, obtain optimum incline angle by regulating the height of upper connector, simultaneously can determine a suitable angle of rotation, make Floor Pump be convenient to firmly operation, at ordinary times, Floor Pump is placed between standpipe and the back mud watt, is not easy to break or break; Floor Pump and eccentric wheel locking piece can be selected the product of commerce-change for use, need not redevelopment, thereby total manufacturing cost are low; In the storage hole of handle, depositing the valve skin, but instantaneously changing, more convenient use.
