The utility model has the advantage that since the pretensioner is introduced in the door and the window, and the self-locking function can be realized during the process of closing the doors and windows at a high speed by using the pretensioner, so as to achieve the purpose of avoiding the phenomenon of trapping caused by quickly closing the doors and windows.
Description
Technical field
The utility model relates to a kind of door, window, particularly a kind of door, window with finger pinch device.
Background technology
For the door and window that adopts hinge, hinge, when door or window are in open mode, might be because wind, child be played etc. reason, door, the natural quick closedown situation of window take place.Just be easy to cause this moment the tong incident to take place, the lighter may cause finger swelling, and weight person may cause the comminuted fracture of finger.Therefore there is great potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, can prevent door, the door with anti-tong function of window tong, window and provide a kind of.
A kind of door, window with finger pinch device, its structural feature is: be provided with the pre-tightening device between door, window and door, window fixed frame.
Between door, window and door, window fixed frame, the pre-tightening device is set, utilize the pre-tightening device, when door or window are subjected to applied external force and during quick closedown, pre-tightening device between door, window and framework can block rapidly when being subjected to quick impact force again, and make door, window can't be closed, thereby avoid finger to be clamped in closed instant by door, window.
Described pre-tightening device includes oil cylinder, piston and push rod, push rod is connected with piston, in the oil cylinder cavity, be provided with the oil cylinder cavity is divided into, following two-part taper valve seat, and the spool that matches with valve seat, the big end of taper valve seat is towards piston, spool separates with valve seat when normality, in the cavity of oil cylinder, store fluid oil, pasta in the described cavity is all the time above the upper surface of valve seat, described push rod is connected with an executive item, described executive item is along door, the closing direction of window is the setting at certain inclination angle, it is for to be provided with from high to low along closing direction, and that the high end on the executive item is than door, the window height, that end ratio door that executive item is low, window is low, the low side of push rod and executive item is fixed, and drives the high-end rotation of executive item around executive item.
The pre-tightening device of this structure, in use, it is installed on the upper door frame place, and make wherein executive item towards door, the closing direction of window, and arrange from high to low along closing direction, when door or window are slowly closed the executive item place that enters the pre-tightening device, because the high-end door that is higher than of executive item, window, therefore, door, or window can slowly enter executive item, and along with moving on of door and window, executive item will be by the jack-up that makes progress around its that high end, the executive item of jack-up drives coupled push rod and moves upward, the push rod that slowly moves upward drives piston and moves upward, thereby the oil that promotes the piston top upwards flows, and the oil that flows drives spool and moves upward, oil also flows into the cavity on oil cylinder valve seat top from the gap between valve seat and the spool simultaneously, until valve seat and spool closure.When door or window quick-make, because excessive velocities, therefore make the piston oil in the extrusion oil cylinder upwards fast, thereby promote spool fast and the valve seat closure, after spool and the valve seat closure, because the oil of valve seat below can't enter the oil cylinder cavity of valve seat top, thereby makes that piston can't continue to move upward, thereby makes push rod to move, this just makes that the executive item that links to each other with push rod can't move, thereby badge is lived, make door, window can't realize closure, and then realize anti-tong function.
Described executive item is for to be made of two strip shape bodies that are hinged to certain angle mutually, and a strip shape body wherein is used for fixing, and another strip shape body is connected with push rod.
Described spool is a kind of spherical spool.
Described spherical spool is fixed by a pull bar, described pull bar passes the through hole that is arranged at spherical spool axial line, be provided with keeper at the pull bar end that is positioned at below the spool, described pull bar stretches out in oil cylinder, be provided with screw thread in the pull bar upper end, pull bar nut check is provided with spring between the nut fixed end of pull bar and keeper fixed end, spring housing is loaded on the pull bar.
Spool is adopted the fixing of this form, just can pass through the distance between the adjusting yoke top nut relative positioning spare, thereby realize the distance of the relative valve seat of regulating spool, thus the range ability of control push rod, to adapt to the door of plurality of specifications.
Described pre-tightening device can also be: comprise the slideway of wedge shape, spool device mandrel, connection cord, pulley, pulley are installed on the spool device mandrel, and pulley can move along slideway, be provided with along slideway pivot holder that extend, flute profile in the both sides of slideway, connection cord is wound on the mandrel.
The pre-tightening device of this form in use, is installed on whole pre-tightening device on that side door, window frame that is used for fixing door, window, and the other end of connection cord is fixed on door, the window.When door or window are slowly closed, the pulling connection cord launches gradually, when door or window quick closedown, then will make connection cord drag the volume mandrel moves along the small end of wedge shape slideway rapidly, can't rotate until blocking pulley, thereby mandrel can't be rotated, and connection cord can't continue to launch, thereby makes door, window can't realize closure.
In sum, advantage of the present utility model is:
The utility model is introduced the pre-tightening device in door, window, utilize the pre-tightening device to run into door, can realize the function of self-locking during the window scram, prevents the generation because of the tong phenomenon that quick closedown was caused of door, window to reach.
