Description
Technical field
The utility model relates to a kind of folding seat steel pipe lockable mechanism.
Background technology
Existing folding seat steel pipe adopts rocker switch type lockable mechanism, and this mechanism exists complex structure, installs the defect inconvenient, volume is too fat to move.Lockable mechanism.This device is a set of chair lockable mechanism, and it changes former rocker switch type lockable mechanism into open by push-button locking mechanism.
Summary of the invention
The purpose of this utility model is: provide a kind of folding seat steel pipe lockable mechanism, adopts open by push-button locking mechanism, reduces product cost, simplify installation steps, decrease number of parts, add locking reliability.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of folding seat steel pipe lockable mechanism, include lock housing, lock core, limited cap and spring, described lock housing upper surface has the longitudinal hole running through lock core, and described built-in lock pin is in lock housing, and lock housing upper surface is extended on the top of lock core; Described lock housing side also has the transverse holes staggered with longitudinal hole, described steel pipe runs through described transverse holes, the aperture of described transverse holes is consistent with steel pipe aperture, and described lock core correspondence position has the elongated through-holes that steel pipe runs through, and the aperture of described elongated through-holes is greater than the aperture of steel pipe; Described limited cap and spring is provided with between the lower surface of lock core and adjacent lock housing, the corresponding limited cap in described lock core lower surface is provided with spacing hole, the cap body of limited cap is through spacing hole, the brim of a hat and the lock core lower surface of limited cap offset, spring one end and lock housing lower surface inwall offset, and the other end and cap body inwall offset.
The elongated structure of the described the brim of a hat.
Described lock housing is provided with the lug be connected with folding seat, and described lug is provided with installing hole.
Operation principle of the present utility model is: the through hole in lock housing and diameter of steel tube are equally large, and therefore lock housing can only drive the lock core in it, spring, limited cap to move up and down along steel pipe axis.When not to spacing hole on steel pipe, lock core is drawn in lock housing by the limited cap heading on steel pipe, and spring is now pressed in limited cap; When spacing hole overlaps with limited cap, limited cap under the action of the spring, is headed in steel pipe, thus the motion of restriction lock housing; Pressing lock core, makes limited cap depart from the spacing hole of steel pipe, i.e. adjustable steel pipe position.
The utility model has the advantage of: 1, adopt open by push-button locking mechanism, weight reduces 25%, volume reduces 35%, thus reduces product cost, simplify installation steps, decrease number of parts, add locking reliability; 2, structure is simple, low cost of manufacture, result of use are good.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure decomposing schematic representation;
Fig. 2 is that steel pipe embeds lock core structure schematic diagram;
Fig. 3 is that steel pipe and lock core depart from schematic diagram.
Detailed description of the invention
With reference to accompanying drawing 1-3, a kind of folding seat steel pipe lockable mechanism, includes lock housing 1, lock core 2, limited cap 3 and spring 4, and described lock housing upper surface has the longitudinal hole running through lock core, and described built-in lock pin is in lock housing, and lock housing upper surface is extended on the top of lock core; Described lock housing side also has the transverse holes 11 staggered with longitudinal hole, described steel pipe 5 runs through described transverse holes, the aperture of described transverse holes is consistent with steel pipe aperture, and described lock core correspondence position has the elongated through-holes 21 that steel pipe runs through, and the aperture of described elongated through-holes is greater than the aperture of steel pipe; Described limited cap and spring is provided with between the lower surface of lock core and adjacent lock housing, the corresponding limited cap in described lock core lower surface is provided with spacing hole 22, the cap body of limited cap is through spacing hole, the brim of a hat 31 and the lock core lower surface of limited cap offset, spring one end and lock housing lower surface inwall offset, and the other end and cap body inwall offset.The elongated structure of the described the brim of a hat.Described lock housing is provided with the lug 12 be connected with folding seat, and described lug is provided with installing hole 13.
Above embodiment is only case of the present utility model, and any replacement done according to the utility model spirit is all interpreted as not departing from protection domain of the present utility model.
