Description

Technical Field

[0001] The utility model relates to the technical field of lifting windows, in particular to a lifting window. Background Art

[0002] In architecture, windows refer to openings built on walls or roofs to allow light or air to enter a room. While ensuring sufficient sunlight in the room, they can also protect against rain and wind. Modern windows are divided into several opening forms, including casement, sliding, top-hung, bottom-hung and pull-up.

[0003] Among them, casement, sliding, top-hung and bottom-hung windows all require a certain area to be reserved outside the window for the window to be opened. The opened window extends out of the wall, which is easy to block the view and is easily damaged by moving objects outside. The lifting window is a door and window that uses the up and down lifting and pulling opening method. Both the upper and lower leaves can be opened. After opening, the upper and lower leaves will not extend out of the wall.

[0004] However, although the existing lifting windows can realize the function of opening and closing both the upper and lower sashes, their air tightness, water tightness, thermal insulation and wind pressure resistance are poor, and cannot meet the performance requirements of new buildings. In addition, they need to be manually pulled to achieve opening and closing. The manual pulling method also makes it impossible to design the lifting windows larger, otherwise their performance will be worse, and they are not suitable for manual pulling operations.

[0005] Furthermore, the anti-falling of mobile fans is related to safety issues and has always been a focus of attention in the industry. How to design a lifting window with good wind and pressure resistance, high anti-falling safety, and suitable for coastal cities is the subject of this case. Utility Model Content

DETAILED DESCRIPTION

[0031] The utility model provides a lifting window, such as Figure 1-5As shown, it includes a window frame, a movable fan, and a lifting drive mechanism. The lifting drive mechanism is installed on the window frame, and a track is installed and fixed on the side frame of the window frame. The movable fan is driven by the lifting drive mechanism and is lifted and lowered on both sides of the window frame along the track: a translation drive mechanism is also arranged on the window frame, and the track includes a vertical groove and a plurality of transverse grooves. A plurality of racks are fixed on the side of the movable fan, and a rotating shaft is vertically pivoted on the side frame of the window frame, and a plurality of gears are fixed on the rotating shaft. After the movable fan is lifted, the plurality of racks are meshed with the gears in sequence, and the rotating shaft is driven to rotate by the translation drive mechanism, thereby driving the movable fan to slide horizontally in the transverse groove, thereby realizing the closing of the movable fan.

[0032] Different from the traditional lifting track, such as Figure 1 As shown, the track in this embodiment is divided into a vertical groove and a horizontal groove, which facilitates the running trajectory of the mobile fan that first rises and then moves horizontally. When lifting vertically, it is driven by a lifting drive mechanism, which is not limited to one form, such as a screw slider transmission method, and a slide groove is opened on the slider. The mobile fan is slidably placed on the slide groove, and the motor drives the screw to rotate. After the slider drives the mobile fan to rise and fall, the mobile fan is then translated in the slide groove. In this embodiment of the case, it is driven by a lifting motor, and the lifting motor is connected to a rope, and the rope is connected to the mobile fan to realize the lifting and lowering of the mobile fan. The driving method of the lifting motor connected to the rope, when the mobile fan is translated, the rope pulled by the lifting motor is in a relaxed state, which does not affect the horizontal movement of the mobile fan.

[0033] Furthermore, in the above embodiment, if Figure 1 and 2 As shown, in order to make the moving fan move more smoothly, a plurality of pulleys are rotatably connected to the side of the moving fan. The pulleys are restricted from sliding in the track, which also ensures the correctness of the moving trajectory of the moving fan.

[0034] In this embodiment, selected Figure 1-4 As shown, there are two groups of the plurality of gears, and there are two groups of racks meshing therewith.

[0035] like Figure 1 and 2 As shown, there are three transverse grooves, two at the upper end and one at the lower end, and the corresponding pulleys are three groups, and the positions between the three groups of pulleys are consistent with those between the transverse grooves.

[0036] like Figure 1 As shown, the distance between the two groups of gears is smaller than the distance between the pulley of the lowest group and its adjacent upper group of pulleys, so as to ensure that the pulley does not interfere with the translation motor and the gear when translating outward.

[0037] Further, preferably, the two groups of gears include an upper gear and a lower gear, the two groups of racks include an upper rack and a lower rack, the diameter of the lower gear is smaller than the upper gear, the thickness of the lower rack is greater than the upper rack, and when the moving fan is raised or lowered, the upper rack does not contact the lower gear, the upper gear meshes with the upper rack, and the lower gear meshes with the lower rack. Such an arrangement effectively prevents interference between the upper rack and the lower gear during the rising process of the moving fan, but does not hinder the meshing of the upper gear with the upper rack, and the lower gear with the lower rack.

[0038] Furthermore, when the movable fan moves horizontally, it is driven by a horizontal driving mechanism, and there are various transmission methods. A double-headed motor may be installed at the upper end of the window frame, and the double-headed motor may be rotatably connected to the rotating shafts on both sides of the window frame through a transmission shaft, thereby driving the rotating shafts on both sides of the window frame to rotate. Alternatively, as shown in 2, in the embodiment of this case, the horizontal driving mechanism is a translation motor, and the translation motor is a double-headed motor. The upper and lower output ends are respectively connected to the rotating shafts, thereby driving the rotating shafts to rotate.

[0039] Furthermore, the teeth of the gear and rack are in a shuttle shape, so that the meshing between the gear and the rack is smoother.

[0040] like Figure 4 and 5 As shown, it also includes a locking mechanism, which includes a locking cylinder, an electric push rod, a transmission rod, a transmission rod connecting block, a locking point, and a lock seat. The transmission rod is slidably connected to the grooves of the upper frame, side frame, and horizontal center stile of the window frame. The lock seat is fixedly connected to the profile grooves of the upper frame and lower frame of the movable fan. The locking cylinder is installed in the profile cavity of the upper frame of the window frame. The electric push rod is connected to the locking cylinder. One end of the transmission rod connecting block is connected to the electric push rod, and the other end is connected to the transmission rod, which is used to push the transmission rod to slide. The locking point is fixedly connected to the transmission rod.

[0041] The outer side of the locking mechanism is connected to a detachable maintenance plate, which is convenient for disassembling the maintenance plate and repairing the locking mechanism.

[0042] Working principle: When the lifting window is used, Figure 1 As shown on the right, when in the open state, the movable fan is located on the side of the fixed fan and at the lower end of the window frame. At this time, the window is in the open state and the ventilation effect is optimal. When the window needs to be closed, the lifting motor is started. Under the action of the lifting motor, the rope is pulled to pull the movable fan upward, and the slides on both sides of the movable fan slide in the vertical grooves of the track, as shown in FIG. Figure 1As shown in the middle figure, after the movable fan has risen, the multiple sets of racks on both sides of the movable fan mesh with the gears on both sides of the window frame. At this time, due to the distance between the fixed fan and the movable fan, the window is in a micro-ventilation state. Under the coupling of the gear rack, the movable fan exhibits better wind resistance and pressure resistance. After starting the horizontal motor, the gear is driven to rotate, thereby prompting the movable fan to move horizontally toward the fixed fan, and the pulley slides in the corresponding horizontal groove. At this time, the horizontal motor can be stopped at any time to control the distance between the fixed fan and the movable fan to achieve a micro-ventilation state, as shown in FIG. Figure 1 As shown in the left figure, when the window is in the closed state, the movable sash is closed on the upper end of the fixed sash to prevent the movable sash from falling. Under the coupling of the gear rack, the movable sash has better sealing performance.

[0043] In summary,

[0044] This lifting window changes the track of traditional lifting and pulling windows, and then changes the running trajectory of the moving fan, realizing a new operating mode of first vertical lifting and then horizontal movement. There are three states: open, lift and close. The moving fan can be frozen when it is lifted to the top. A horizontal space is left between the moving fan and the fixed fan, so that the window is in a micro-ventilation state.

[0045] The lifting window is driven by a translation motor, and the gear rack is engaged to achieve the translation of the movable fan. Under the coupling of the gear rack, better pressure and wind resistance and stronger sealing effect are achieved. When the movable fan is in the closed state, the movable fan is placed directly above the fixed fan, and the support of the fixed fan helps prevent the movable fan from falling.

[0046] The teeth of the gear and rack of the lifting window are in a shuttle shape, which facilitates smoother meshing and reduces damage to the gear and rack.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
