Abstract
The utility model relates to a bidirectional transmission for casement doors/windows, and the bidirectional transmission comprises a box body, a first gear and a rack. The bidirectional transmission for casement doors/windows is characterized in that the rack comprises an upper rack and a lower rack; the upper and lower racks are glidingly arranged on the box body, respectively; the box body is internally provided with a second gear; double-sided teeth are arranged on the upper rack and are respectively meshed with the first and second gears; the pitch of the meshing surface of the upper rack and the first gear is twice of the pitch of the meshing surface of the upper rack and the second gear; the lower rack is also meshed with the second gear; the running lengths of the upper and lower racks are the same; and the upper and lower racks which are 20mm long are respectively connected with corresponding transmission rod on a window sash. According to the bidirectional transmission for casement doors/windows, by rotating a handle connector, the upper and lower racks can move rapidly, so that the transmission is flexible and labor-saving, the abrasion of the handle connector is decreased and the service life is prolonged; and when being applied to the window sashes or door leaves, the bidirectional transmission for casement doors/windows has the advantages of bidirectional locking, stable running and strong practicability.
Description
Technical field
The utility model relates to a kind of door and window Hardware fitting, and what be specifically related to is the flat-open door and window bidirectional driver.
Background technology
In the modern architecture field, the most widely used is various alloy door and windows, adopts alloy profile as Door and window frame and door, sash.Wherein bar is made of section bar coating glass, the outer edge of section bar is equiped with linkage, linkage is provided with the lock dot structure that matches with door and window, be equipped with on sash between handle and linkage and be provided with driver, driver usually coordinates by physical dimension and is installed in section bar, driver is provided with intermeshing switch tooth bar and travelling gear, circular motion is changed into the rectilinear motion of translation.The door and window actuator of this structure, its switch gear and travelling gear are all to adopt die casting, in long-term the use, wear and tear larger, thereby cause broken teeth, cause door and window not open.So, just have human hair to understand the strong and long-lived door and window actuator of interchangeability.Look into Chinese patent database, obtaining notification number is CN201802142U, name is called the utility model patent of door and window actuator, following content is disclosed: a kind of door and window actuator, it is characterized in that this driver comprises that housing, tooth bar, gear and pull bar, the engagement of described rack and pinion are placed in described housing, described pull bar is through described housing, and described tooth bar is arranged on described pull bar, and described gear and tooth bar adopt powder metallurgy to be made.The door and window actuator of this structure, solved short-life defective, but it is a kind of one-way driver, adopts a pull bar to come linkages all on the transmission sash and lock point apparatus, transmission direction is single, can not well satisfy user's the higher demand of many-side.
Summary of the invention
In view of the deficiency that background technology exists, the technical problems to be solved in the utility model is that Bidirectional driving can be provided, the flat-open door and window bidirectional driver that increases the service life.
for this reason, the utility model adopts following technical scheme to realize: a kind of flat-open door and window bidirectional driver, comprise box body, the first gear and tooth bar, it is characterized in that described tooth bar has upper rack and lower tooth bar, and slidably be arranged on box body respectively, be provided with the second gear in described box body, described upper rack has double cog, respectively with described the first gear, the second gear engagement, wherein, the tooth pitch of upper rack and the first gear field of conjugate action is the twice with the second gear field of conjugate action tooth pitch, and lower tooth bar also meshes with described the second gear, described upper rack is connected with corresponding drive link on door leaf or sash respectively with lower tooth bar.
Described the first gear is non-complete gear, and this non-complete gear has three teeth, and it is octadentate when being complete gear.
This structure of the present utility model, pull handle and drive the first gear, the transmission upper rack, upper rack transmission the second gear, then tooth bar under transmission are after the rack-driving of up and down, just the drive link with their connections respectively links, with with the linkage on the transmission sash and each lock point, make and window or to close window very light.Because the tooth pitch on two sides on upper rack differs one times, so as long as with very little power, just transmission tooth bar up and down fast has stable drive labour-saving characteristics.
Description of drawings
The below further describes details of the present utility model more by reference to the accompanying drawings.
Fig. 1 is structure chart of the present utility model.
The specific embodiment
With reference to accompanying drawing, this flat-open door and window bidirectional driver, comprise box body 2, the first gear 5 and tooth bar, wherein, described the first gear 5 is non-complete gear, and this non-complete gear has three teeth, when it is all gear, the full-depth tooth number is octadentate, the gear of this structure is large modification coefficient, the ultrashort tooth involute gear of large pressure angle, solved the following easily problem of undercut of 17 teeth, and in the situation that reference circle is constant, guaranteed running length, save space and material, can increase the facewidth and tooth pitch again, but with the just following tooth bar up and down of transmission of very little power.Described tooth bar has upper rack 3 and lower tooth bar 1, and slidably is arranged on respectively on box body 2, namely has a notch (not shown) that supplies tooth bar to move in the both sides of box body 2.Be provided with the second gear 4 in described box body 2, described upper rack 3 has double cog, respectively with described the first gear 5, the second gear 4 engagements, wherein, the tooth pitch of upper rack 3 and first gear 5 fields of conjugate action is the twices with the second gear 4 field of conjugate action tooth pitches, like this, the one side that the first gear 5 and upper rack 3 tooth pitches are large coordinates, and the little one side of the second gear 4 and upper rack 3 tooth pitches coordinates, and lower tooth bar 1 also meshes with described the second gear 4, and the handle on the first gear 5 sash connects, and described upper rack 3 is connected with corresponding drive link on sash respectively with lower tooth bar 1.When pulling handle, rotate the first gear 5, and mobile upper rack 3, then drive the second gear 4, and mobile lower tooth bar 1, after up and down tooth bar 3,1 moves, the corresponding drive link that links, the linkage on transmission door leaf or sash and each lock point, just can easily open door leaf or sash, the counter-rotating handle, the corresponding drive link that just links can be locked with door leaf or sash with linkage and each lock point.This structure of the present utility model, stable drive, reliability is high, pulls handle laborsaving, has reduced the wearing and tearing of handle for driving spare, has improved application life, has extraordinary practicality.
