Description
Technical Field
The invention relates to an auxiliary window opening and closing tool, which is suitable for window structures such as aluminum alloy doors and windows, curtain walls and the like, in particular to a linkage multi-point chain type window opener.
Background
Conventional chain type window openers do not have the ability to drive a lock point and can only push out and pull back a window. The locking point of the window is actuated by another mechanism or is not itself locked. If another mechanism is needed to drive the locking point, two actions are needed, the locking point is firstly opened, and then the chain type window opener is shaken to push out the window; the window is closed and vice versa. If the locking point is not added, the air tightness and the water tightness of the window cannot be met.
Disclosure of Invention

The worm gear and worm mechanism comprises an anti-bending chain 11, a chain wheel 10, a worm wheel 13 and a worm 14. The worm 14 is connected with the screw rod 6 through a connecting sleeve 8, and the screw rod 6 and the worm 14 can coaxially rotate. The worm 14 and the worm wheel 13 are engaged with each other, and the worm wheel 13 is fixed coaxially with the sprocket 10. The sprocket 10 and the anti-bending chain 11 are engaged with each other. The worm 14 rotates to drive the worm wheel 13 to rotate, the worm wheel 13 drives the chain wheel 10 to rotate, and the chain wheel 10 drives the anti-bending chain 11 to stretch.
The linkage mechanism comprises a shifting fork piece 15 and a linkage piece 16, wherein the shifting fork piece 15 is provided with a groove, the groove inclines for a certain angle along the direction of the window frame, is not vertical to the window frame and is used for accommodating the driving roller 9. The fork element 15 is connected to the chain head 12 via a linkage 16. The fork element 15 is in turn connected to a drive rod 19. The linkage mechanism is arranged in a box body structure, and the box body structure is provided with a linkage part cover 17, so that the maintenance is convenient to open.
The end of the drive bar 19 is configured with a boss 23.
Referring to fig. 3 and 4, the anti-misoperation device is used for being fixedly installed on the window sash and comprises an accommodating chamber, and a spring 22, a cylindrical pin 20 and a square pin 21 which are installed in the accommodating chamber; the square pin 21 is connected with the spring 22, the cylindrical pin 20 and the square pin 21 are integrally formed, and the cylindrical pin 20 can extend out of the accommodating chamber under the action of the elastic force of the spring 22; the accommodating chamber is matched with a boss 23 at the end part of the transmission bar, so that the square pin 21 can be clamped into the boss 23 along with the extension of the cylindrical pin 20 to limit the movement of the transmission bar 19; when the cylindrical pin 20 is compressed into the housing, the square pin 21 is also compressed, thereby exiting the boss 23, removing the restriction and allowing the driver blade 19 to move relative to the anti-tamper.
Above-mentioned linkage multiple spot chain formula ware of windowing, the rotatory number of turns of lead screw and the nut distance of marcing, sprocket drive prevent curved chain walking distance, prevent that the formation of mistake operator to the restriction of drive strip distance of moving, lock point locking lock seat needs mutually support, can guarantee to close the casement after the lock point just march to lock seat position and close the lock.
For example, every time the input end 3 rotates one turn, the screw rod 6 rotates one turn, the nut 7 on the screw rod 6 travels 4mm (here, it can also be set as 6mm, 8mm, etc., which is related to the lead of the screw rod), meanwhile, the worm 14 drives the worm wheel 13 to rotate 45 degrees (here, it can also be set as 60 degrees, 90 degrees, etc., which is related to the transmission ratio of the worm and gear), and the worm wheel 13 drives the sprocket 10 to drive the anti-bending chain 11 to travel 7mm (calculated according to the pitch 9.525mm of the chain). The stroke of the locking point 1 for locking the locking seat 2 is 16mm, under the condition, the lead screw 6 needs to rotate for 4 circles, and meanwhile, the anti-bending chain 11 needs to stretch out for 28mm, so that the anti-bending chain 11 can freely stretch out for 28mm in the opening process of the locking point 1, and the locking point can be opened and the chain can be pushed out simultaneously.
Referring to fig. 5, the process of opening the window sash is as follows: the input end 3 rotates for 4 circles, the screw 7 and the driving roller 9 move for 16mm, the anti-bending chain 11 and the chain end 12 move for 28mm freely, after the free movement is finished, the anti-bending chain 11 can push the force out of the window sash, the window sash and the window frame are separated by a certain distance, in the process, the cylindrical pin 20 of the anti-misoperation device 18 is gradually far away from the window frame and gradually extends out of the accommodating chamber under the elastic force of the spring 22. Then the driving roller 9 and the shifting fork 15 are separated and continue to travel along with the screw 7; the cylindrical pin 20 on the anti-misoperation device is completely popped out, and the square pin is clamped between two adjacent bosses of the transmission strip to limit the transmission strip to move continuously; when the window sash is closed, the shifting fork piece 15 and the driving roller 9 can be smoothly positioned.
The process of closing the sash is as follows: the input end 3, the screw 7 and the driving roller 9 are rotated reversely to move reversely, the shifting fork piece 15 on the window sash is met, the anti-bending chain 11 is continuously withdrawn, the window sash is closed until a cylindrical pin on the anti-misoperation device is propped against the window frame and is continuously pressed into the accommodating chamber, the driving roller 9 enters a groove of the shifting fork piece 15 at the moment, meanwhile, a square pin 21 of the anti-misoperation device is withdrawn due to the pressing of the cylindrical pin 20 and is pulled away from a boss 23 of the transmission strip, the transmission strip 19 is released, the screw 7 continues to move for 16mm, and the locking points of the shifting fork piece 15 and the transmission strip 19 are driven to be inserted into a locking seat of the window frame to lock the window; the chain end 12 can travel freely 28mm during this process.
The inventive concept is explained in detail herein using specific examples, which are given only to aid in understanding the core concepts of the invention. It should be understood that any obvious modifications, equivalents and other improvements made by those skilled in the art without departing from the spirit of the present invention are included in the scope of the present invention.
