Abstract
The utility model belongs to the technical field of accessories for architectural doors and windows, and in particular relates to a large center distance bidirectional internal side-hung transmission locking device for doors and windows. The large center distance bidirectional internal side-hung transmission locking device for the doors and the windows comprises two gear boxes which are riveted together, wherein a fixing plate is fixed on the bottom surface of each gear box; a driving gear is fixed between the two gear boxes; the driving gear is meshed with an upper sliding plate and a lower sliding plate which is arranged above the fixing plates. The large center distance bidirectional internal side-hung transmission locking device for the doors and the windows is characterized in that a driven gear is meshed above the lower sliding plate; a gear shaft is inserted into the central hole of the driven gear; and the gear shaft is fixed between the two gear boxes. The locking device disclosed by the utility model has the beneficial effects that center distance is increased through two gears, so as to achieve use of the bidirectional internal side-hung transmission locking device when the center distance is comparatively large; and the locking device is simple in structure, convenient to operate, easy to process and wide in application range.
Description
(1) technical field
The utility model belongs to use in construction of door and window accessory technical field, and particularly a kind of door and window is with the two-way inward opening driving lock of large center to center distance.
(2) background technology
At present, in the building doors and windows field, the plastics casement window opening inwards is used widely with its good watertightness, tightness, Wind-Pressure Resistance, heat insulating ability.And the inward opening driving lock is to guarantee the requisite selection of above-mentioned superperformance.Wherein two-way inward opening driver owing to having the effect that prevents that door and window is sagging, is widely used.This type of driving lock slides up and down sliding panel to realize by rotating handle the device that prevents that door and window is sagging with regard to referring to.Its principle is that sliding panel is divided into two sliding panels in up and down, be engaged on gear both sides according to relative direction, under the operation of handle, sliding panel transmission on travelling gear and locking device and drive some tapered ends and move to two rightabouts simultaneously, stressed decomposition when the lock point is moved in lock dog reaches a kind of equilibrant force and avoids sash sagging.Thereby realize anti-drop and locking effect to door and window.But due to incomplete restriction of prior art, the structure of common bidirectional driver is only used when center to center distance less (9mm or 15mm).Cause the wheel backplate longer when center to center distance is larger, easily distortion in processing.Door is 20mm, 30mm, 35mm, 45mm with driver center to center distance specification substantially, and the structure of common bidirectional driver does not realize.
(3) summary of the invention
The utility model is in order to make up the deficiencies in the prior art, provide a kind of simple in structure, easy to operate, be easy to process, door and window applied widely is with the two-way inward opening driving lock of large center to center distance.
The utility model is achieved by the following technical solution:
A kind of door and window is with the two-way inward opening driving lock of large center to center distance, comprise two gearcases that are riveted together, the gearcase bottom surface is fixed with fixed head, be fixed with the lower slider plate that driving gear, driving gear are engaged with upper sliding plate and are arranged at the fixed head top between two gearcases, it is characterized in that: be engaged with driven gear above described lower slider plate, be equipped with gear shaft on the interstitial hole of driven gear, gear shaft is fixed between two gearcases.
Described upper sliding plate and lower slider plate are meshed with driving gear and driven gear by engaging hole respectively.
There are a end that engaging hole is arranged on an end, driven gear, lower slider plate of engaging hole and fixed head middle part to be successively set between two gearcases on described driving gear, upper sliding plate from top to bottom.
Fix in the middle part of described gearcase and fixed head.
Offer some strip through holes on described fixed head, be equipped with respectively pin on the strip through hole, pin and upper sliding plate or lower slider plate are fixedly connected.
Described pin below correspondence is provided with pin block.
Be provided with the rotation square hole on described driving gear.
The beneficial effects of the utility model are: strengthen center to center distance by Double-gear, the original gear diameter is constant, and the slide plate bending is highly constant, and gearcase length is constant, thereby realizes the use of two-way inward opening driving lock when center to center distance is larger; Simple in structure, easy to operate, be easy to processing, applied widely.
