Abstract

The utility model discloses a device for inflating and the saddle height-regulating of the bicycle, mainly comprising a vertical tube, an air stop plug, a piston rod handle, a locker, a cup and a rubber tube. People twist the lock handle under the saddle and both hands have the saddle moved up and down, and the air is pressed into tires; the tooth space of the piston rod handle has the function of clamping the saddle, and locking the handle can adjust the height of the saddle without tools adjusting. The utility model is very convenient and reliable, and has no influence on the strength and appearance of the bicycle.

Description

Device for inflating and saddle height-regulating of bicycle

The utility model relates to the inflation mechanism on a kind of bicycle.Particularly be installed in the interior inflation of bicycle tripod pipe and directly adjust a device of saddle height with hand.

The inflation of existing bicycle is small-sized, medium-sized to play the vapour tube or heat pump carries out with independent.With the shortcoming of beating vapour tube and heat pump is to carry inconvenience, and the cost of vapour tube heat pump is also expensive, also will spend great deal of steel.Shortcoming with small-sized vapour tube is a spended time, because the vapour bobbin is little, the leather cup reciprocal time on the piston rod is not durable too much, adjusts a seat saddle and just wants wrench.

In sum, the purpose of this utility model is to be integrated vapour tube and bicycle, adjusts seat saddle height without wrench, reduces material consumption, reduces cost, and convenient inflation and the convenient seat saddle of adjusting are suitable for attractive in appearance, economy and durability to reach.

Task of the present utility model is finished as follows, it is to utilize the bicycle tripod standpipe to do to play the vapour bobbin, a dress choke plug in the spider standpipe, piston rod and leather cup are directly put in the standpipe, and present saddle lock bolt place refills the lifting that a special latching device comes control plunger bar and seat saddle.Now make things convenient for bicycle inflation and the device of adjusting seat saddle height to be described in further detail in conjunction with the accompanying drawings.

Device by spider standpipe (1) (abbreviation standpipe) and choke plug (2) locker (8) piston rod handle (9) is to realize inflation like this and adjust seat saddle height.Then can tighten up piston rod handle (9) when the position clamp handle (7) turned round to the long and two-short dash line of handle can not lifting see figure, and a seat saddle (10) also is fixed.Otherwise just can with the hands catch a saddle (10) up-and-down movement, piston rod (3) and leather cup (5) also just follow motion to make gas pass through gas-tpe fitting (4) and rubber tubing (6) is compressed into tire.Before gas filled device is installed, the slotted wall burr in the handle riser (1) to remove with instrument, again choke plug (2) is put into standpipe (1) inner bottom part and compress.Choke plug (2) preferably selects for use aluminium to make.After installing, choke plug (2) must not leak gas.Bore a hole tapping again of leading to choke plug (2) with drill bit outside standpipe (1), be tightened on standpipe (1) and the choke plug (2) wearing a rubber grommet on the adaptor union (4) then again, piston rod (3) combines or seam with the available screw of piston rod handle (9).Piston rod handle (9) installs to qualifying bit postpone in the locker (8) and twists clamp handle (7) with hand that a saddle is fixed is not loose.Pin on the locker handle (7) is in the backlash (11) that is stuck in above the piston handle (9), sees figure.Seat saddle (10) can directly twist clamp handle (7) with hand with people's height and adjust height.Than saving trouble conveniently with wrench.

This device confirms through investigating, really convenient and practical reliable, if being drained back only need, gas in the tire can beat foot to gas in about 5 minutes, friction temperature in leather cup (5) and the standpipe (1) is about about 30 ° of degree, this temperature and above-mentioned structure do not influence the material of bicycle basically, and this device is well suited for bicycle producer and cooperates processing when producing spider.

Claims

1, a kind of bicycle inflation and the device of adjusting seat saddle height is characterized in that, it comprises that spider is responsible for [1]; Be loaded on described spider and be responsible for the adaptor union [4] that the choke plug [2] in [1] links; Be contained in the rubber tubing [6] on the adaptor union [4]; Be arranged in described spider and be responsible for the leather cup [5] of [1]; Drive the piston rod [3] that described leather cup [5] moves back and forth; The piston rod handle [9] that links with piston rod [3] and be contained in seat saddle [10] on the piston rod handle [9]; Be used to lock the clamp handle [7] that described piston rod handle [9] makes its locker that can not move back and forth [8]; Rotation lock handle [7] can be locked in described piston rod handle [9] on the needed position.
