Abstract

Disclosed is an anti-settling building window transmission locking device. A drive case body is made up of the mutual lock jointing of the front and back positioning plates, and the inner of the case body is assembled with single-sided three gears driving gear and a driven gear. The driving gear meshes with a gear rack whose lower end is provided with a moving-strip toothed rack. The driven gear respectively intermeshes with the moving-strip toothed rack whose upper and lower ends are provided with moving-strip toothed racks and the moving-strip gear. The device has the advantages of simple structure, reasonable design, easy mounting and dismounting and low cost. The drive device is adopted, so the opening window can not deform and subside, the service life of entire building window is extended, and simultaneously, the closed effect of the window is made better.

Description

Anti-settling type building window transmission locking device

Technical field

The utility model relates to a kind of building window transmission locking device, and definite a kind of building window of saying so is opened locking device.

Background technology

At present, China's transmission locking device that plastic-steel door and window uses that builds a building is mainly by strap, the centre that is installed in the strap middle part has the gear of driving hole, be installed in the bar of deciding on the strap, be installed on a moving bar of travelling gear one side, the two ends of moving bar respectively have a lock.It is that a kind of unidirectional transmission is all same from the bottom up direction transmission of upper and lower lock, to reach the locking purpose, the long-term mobile from bottom to top and fricative frictional force of lock post of moving lock of using, make sash open the length of side phase to lower stress, easily make the sash distortion, the unlatching limit sinks, and influences the normal switch of sash, the application life of also having reduced door and window simultaneously.

Summary of the invention

The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, opens the anti-settling type building window transmission locking device that sash is difficult for distortion, sinks.

In order to achieve the above object, the technical solution adopted in the utility model is: constitute the transmission device box body by the mutual snapping of front and back location-plate, be equipped with single face three tooth driving gear and the driven gears on the same horizon in it, driving gear is meshed with the moving plate tooth bar that the lower end is provided with, and driven gear is provided with moving plate tooth bar and moving plate tooth bar and driven gear with upper/lower terminal respectively and is meshing with each other.

The utility model has the advantages that:

Simple in structure, reasonable in design, easily installing/dismounting is with low cost, adopts this transmission device, opens the indeformable sinking of sash, has improved the whole service life of building window, makes the sash obturation effect better simultaneously.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

By Fig. 1-Fig. 2 as can be known, the utility model is to constitute the transmission device box body by front and back location-plate 1,2 mutual snappings, be equipped with single face three tooth driving gears 3 and driven gear 4 on the same horizon in it, driving gear 3 is meshed with the moving plate tooth bar 5 that the lower end is provided with, and driven gear 4 with upper/lower terminal moving plate tooth bar 6 is set respectively and moving plate tooth bar 5 is meshing with each other with driven gear 4.The utility model is work like this:

During locking device work, the driving gear 3 that location-plate 1,2 mutual snappings in front and back constitute in the transmission device box bodys turns clockwise, driving gear 5 and moving plate tooth bar 5 be meshing with each other make the moving plate tooth bar left direction move, moving plate tooth bar 5 is rotated counterclockwise with driven gear 4 and is meshing with each other simultaneously, also make driven gear 4 rotations, drive is arranged at the intermeshing moving plate tooth bar in driven gear 4 upper ends 6 and moves to right, make

lock

9,10 that upper and

lower tooth bar

6,5 two ends install along sliding in the slotted hole that has on the fixed head 8, locking device is reached close the window purpose.

Claims

1. an anti-settling type is built the window transmission locking device, comprise fixed head, lock, it is characterized in that: constitute the transmission device box body by front and back location-plate (1), (2) mutual snapping, be equipped with single face three tooth driving gears (3) and driven gear (4) on the same horizon in it, driving gear (3) is meshed with the moving plate tooth bar (5) that the lower end is provided with, and driven gear (4) with upper/lower terminal moving plate tooth bar (6) is set respectively and moving plate tooth bar (5) is meshing with each other with driven gear (4).
