The trailing cable operating mechanism of perambulator pushing hands bar
Technical field
The utility model relates to a kind of perambulator, the trailing cable operating mechanism of perambulator pushing hands bar particularly, and this operating mechanism is used for release of operational lock device or locking.
Background technology
In the prior art, the trailing cable operating mechanism of perambulator pushing hands bar, comprise the pushing hands bar, be fixed in the cover plate on the pushing hands bar, part be inserted in the described cover plate and with the handling knob of its sliding block joint, be arranged in a pair of trailing cable of the inner chamber of pushing hands bar, be provided with runner in the described cover plate inner chamber, this runner is connected with trailing cable, the control of being handled knob, runner rotates and the tractive trailing cable, but runner affects distance shorter to trailing cable, and the stroke of handling knob often also is restricted, and therefore the trailing cable operating mechanism of this perambulator pushing hands bar is not suitable for the long blocking device of some hauling distances that need traction lock.
Summary of the invention
The purpose of this utility model is to provide a kind of affecting apart from the trailing cable operating mechanism than long perambulator pushing hands bar trailing cable.
The technical solution of the utility model is: a kind of trailing cable operating mechanism of perambulator pushing hands bar, comprise the pushing hands bar, be fixed in the cover plate on the pushing hands bar, part be inserted in the described cover plate and with the handling knob of its sliding block joint, be arranged in a pair of trailing cable of the inner chamber of pushing hands bar, have a pair of sliding tray on the described cover plate, be provided with pair of turning wheels in the inner chamber of cover plate, be respectively equipped with a runner fulcrum on described each runner, described each runner fulcrum is inserted in the corresponding sliding tray, the upper end of each runner is connected with a trailing cable, and the bottom of described each runner contacts with handling knob.
The utility model compared with prior art has following advantage:
Owing on the cover board have a sliding tray, and be inserted with the runner fulcrum of runner in this groove, so the runner fulcrum can carry out slide displacement and rotation, under the situation of the identical stroke of handling knob, can make trailing cable affect longer distance.

The specific embodiment
Referring to accompanying drawing, a kind of trailing cable operating mechanism of perambulator pushing hands bar, comprise pushing hands bar [2], be fixed in the cover plate [1] on the pushing hands bar [2], part be inserted in the described cover plate [1] and with handle knob [5] of its sliding block joint, be arranged in a pair of trailing cable [9] of the inner chamber of pushing hands bar [2], have a pair of sliding tray [4] on the described cover plate [1], be provided with pair of turning wheels [7] in the inner chamber of cover plate [1], be respectively equipped with a runner fulcrum [6] on described each runner [7], described each runner fulcrum [6] is inserted in the corresponding sliding tray [4], the upper end of each runner [7] is connected with a trailing cable [9], and the bottom of described each runner [7] contacts with handle knob [5].Described each runner [7] be provided with laterally protrude by activity supporting point [8], should contact with handle knob [5] by activity supporting point [8].When handling knob [5] when moving up, promote to move up by activity supporting point [8], then the runner fulcrum [6] on the runner [7] not only rotates but also slides in sliding tray [4], makes that the trailing cable [9] on the left of the upper end drive of runner [7] on right side moves right; And the trailing cable [9] on drive right side, the upper end of the runner in left side [7] is moved to the left, and finishes the control of trailing cable [6].
