Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a bicycle field especially relates to a axis adjustable bracket.
[ background of the invention ]
The axis among the prior art is installed on the longeron of frame through a installing support, and installation back axis and longeron rigidity, the defect of this kind of structure is: the distance from the middle shaft to the seat can not be adjusted, so that the bicycle can not adapt to riders with different heights by adopting the structure, and the riding comfort of the riders is greatly reduced.
Therefore, there is a need for a bottom bracket adjustable mount that solves the above mentioned problems.
[ Utility model ] content
In order to solve the above problem, an object of the present invention is to provide a middle axle adjustable frame capable of moving axially relative to a longitudinal beam of a vehicle frame.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a bottom bracket adjustable bracket, comprising: the adjustable frame main part and with adjustable frame main part matched with locking lid, be connected through the mounting between adjustable frame main part and the locking lid, axial displacement can be made for the longeron of frame to adjustable frame main part and locking lid, the adjustable frame main part is equipped with the first draw-in groove with longeron matched with, the locking lid is equipped with the second draw-in groove with longeron matched with, the shape after first draw-in groove and second draw-in groove are in the same place is identical with the cross sectional shape of longeron, the adjustable frame main part is equipped with and is used for installing centraxonial mounting hole.
Preferably, the utility model provides a well axle adjustable shelf further sets up to: the cross section of the longitudinal beam is circular, square or oval.
Preferably, the utility model provides a well axle adjustable shelf further sets up to: the fixing piece is a bolt.
Preferably, the utility model provides a well axle adjustable shelf further sets up to: the cross section of the mounting hole is in circular arrangement.
Preferably, the utility model provides a well axle adjustable shelf further sets up to: and the hole shaft of the mounting hole is perpendicular to the longitudinal beam.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model provides a axis adjustable shelf simple structure, simple to operate through with its design for can be for longeron axial displacement, and then adjustable axis is to the distance of seat and the elasticity of chain to can be fit for not the people of co-altitude and ride, improved the comfort level of riding passerby greatly.

[ detailed description ] embodiments
The present invention provides an adjustable middle axle bracket, which is further described in detail with reference to the following embodiments.
Referring to fig. 1 to 3, a bottom bracket adjustable frame includes: adjustable frame main part 1 reaches and can adjust frame main part 1 matched with locking lid 2, be connected through mounting 3 between adjustable frame main part 1 and the locking lid 2, in this embodiment, mounting 3 is the bolt. The adjustable frame comprises an adjustable frame body 1 and a locking cover 2, wherein the adjustable frame body 1 and the locking cover 2 can move axially relative to a longitudinal beam 4 of a frame, the adjustable frame body 1 is provided with a first clamping groove 10 matched with the longitudinal beam 4, the locking cover 2 is provided with a second clamping groove 20 matched with the longitudinal beam 4, the shape of the first clamping groove 10 and the second clamping groove 20 after being combined is identical to the shape of the cross section of the longitudinal beam 4, the adjustable frame body 1 is provided with a mounting hole 11 for mounting a middle shaft, the cross section of the mounting hole 11 is in a circular arrangement, and the hole axis of the mounting hole 11 is perpendicular to the longitudinal beam 4. In this embodiment, the longitudinal beam 4 has a circular cross section, and the first engaging groove 10 and the second engaging groove 20 are both semicircular, but in other embodiments, the longitudinal beam 4 may have a square, oval or other cross section, and the present invention can be implemented.
To sum up, the utility model provides a but axis adjustable shelf simple structure, simple to operate through with its design for can be for longeron axial displacement, and then the elasticity of the distance of adjustable axis to seat and chain to can be fit for not the people of co-altitude to ride, improved the comfort level of riding passerby greatly.
The above-mentioned embodiments are merely illustrative of the principles and effects of the present invention, and some embodiments may be applied, and are not intended to limit the present invention; it should be noted that, for those skilled in the art, without departing from the inventive concept, several variations and modifications can be made, which are within the scope of the present invention.
