Description

Hinge and window

Technical Field

The utility model relates to a hinge which can drive a window to move in a horizontal direction, in particular to a hinge and a window.

Background Art

With the continuous acceleration of urbanization, modern buildings mostly use aluminum alloy windows. When using aluminum alloy windows, you will face the choice of window opening and closing methods. Traditional residential buildings mostly use external casement windows, which have good wind pressure resistance, water tightness and air tightness, and do not occupy indoor space.

At present, the hinges for casement windows on the market either use several interconnected rods to rotate to achieve the opening of the window and the required angle; or use a sliding support structure, through the movement of the slider in the slide rail groove to drive several mutually hinged rods to rotate, so as to achieve the opening of the window and the required angle. However, there are two problems with both methods: First, the maintenance of the window opening angle is completely dependent on the friction force provided by the hinges of several rods, and the stability of the opening angle may be difficult to maintain when encountering strong winds; second, the existing external casement window hinges are difficult to clean the window glass. To clean the glass facing the outside, you need to lean out of the window to clean it, which is not only inconvenient to clean, but also has a high safety hazard. Therefore, it is of great significance to design a hinge that can facilitate window cleaning and enhance the ability to maintain the window opening angle.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

A hinge as shown in Figure 1 includes a base 1, which also includes a plurality of slide grooves formed at intervals on the base. A cantilever assembly is installed on the base 1. The base 1 is movably connected to the cantilever assembly through the slide groove. The cantilever assembly translates along the slide groove so that the cantilever assembly can be unfolded or folded relative to the base.

In one embodiment, as shown in FIG6 , the slide groove includes a first slide groove 13 and a second slide groove 12 which are arranged at intervals and whose center lines are located on the same horizontal line. The slide grooves are both long strips. The base 1 on both sides of the slide grooves is provided with a first lock hole 11 and a second lock hole 14 respectively. A countersunk groove 15 is formed on the bottom surface of the first slide groove 13 near the second lock hole 14. By providing the countersunk groove 15, when the hinge is in a closed state or a normally opened state, the circular slider 73 at the bottom of the fastener can be matched and embedded in the countersunk groove, thereby ensuring that the first sliding cantilever will not move along the first slide groove.

By opening two slide grooves on the base, the cantilever assembly can generate relative movement along the slide grooves. The cantilever assembly can be unfolded or folded during the sliding or rotating process, thereby ensuring the opening angle of the window. By opening two long strip slide grooves, the cantilever assembly can move horizontally along the slide grooves, further increasing the distance between the window and the wall, meeting the user's needs for cleaning the window.

In one embodiment, the cantilever assembly includes a linkage cantilever and a sliding cantilever. The linkage cantilever drives the sliding cantilever to expand or fold. The other end of the sliding cantilever is connected to the slide groove through a connecting piece and can reciprocate along the slide groove. The two groups of cantilever cooperate with each other to drive the window to open and close during the expansion or folding process, so that the window is opened outward at a certain angle and then moves left and right along the slide groove, so that the distance between the window and the side of the wall is increased, and the extra gap makes it convenient for people to reach out to clean the window.

In one embodiment, the linkage cantilever includes a linkage cantilever No. 1 2 and a linkage cantilever No. 2 3. Two connecting holes are provided on the linkage cantilever No. 1 2. The linkage cantilever No. 1 2 is riveted to the column 41 on the sliding cantilever No. 1 4 and the corresponding holes on the linkage cantilever No. 2 3 through the two connecting holes. As the window is pulled, the linkage cantilever No. 1 rotates and drives the sliding cantilever No. 1 4 to move in the slide groove No. 1 13.

Preferably, the sliding cantilever comprises a first sliding cantilever 4 and a second sliding cantilever 5. The middle of the first sliding cantilever 4 is riveted to the corresponding hole on the second sliding cantilever 5 through a round hole, and the two can rotate relative to each other. The side close to the first slide groove 13 is connected to the first slide groove 13 through a fastener 7. By providing the fastener 7, when the window is normally opened, the first sliding cantilever and the first slide groove do not slide relative to each other, and the linkage cantilever only drives the second sliding cantilever to slide along the second slide groove, thereby realizing the normal opening or closing of the window.

As shown in Fig. 7 and Fig. 5, the fastener 7 includes a tightening part 72 at the top and a movable column 71 at the bottom that is detachably connected to the tightening part. The movable column 71 includes a circular slider 73. A threaded rod 74 is vertically formed in the middle of the circular slider 73. The circular slider 73 is matched and inserted into the countersunk slot 15. The threaded rod 74 is threadedly connected to the tightening part 72. Preferably, a hexagonal hole is provided at the center of the tightening part, and the center of the tightening part is threadedly connected to the threaded rod. The tightening part is screwed to fix or separate the tightening part and the movable column, thereby adjusting the state of the No. 1 sliding cantilever, ensuring that the hinge can meet the user's window opening or glass wiping needs when in use, and is more convenient to use.

When the window needs to be opened normally, since the circular slider 73 is matched and inserted in the countersunk slot 15, the circular slider can only rotate in the countersunk slot but cannot move along the No. 1 slide slot, so the No. 1 sliding cantilever cannot move. At this time, only the No. 2 sliding cantilever connected to the damping hinge can slide to ensure the normal opening or closing of the window.

Preferably, one end of the No. 2 linkage cantilever 3 away from the connecting hole is riveted to the No. 2 sliding cantilever 5, and the rotation of the No. 1 linkage cantilever drives the No. 2 linkage cantilever 3 to rotate, and the No. 2 linkage cantilever 3 drives the No. 2 sliding cantilever 5 to move in the No. 2 slide groove 12 while causing relative rotation.

Preferably, one end of the second sliding cantilever 5 close to the second slide groove 12 is connected to the second slide groove 12 through a damping hinge 6, and the rotation angle can be maintained by means of the damping hinge, and the rotation angle of the second sliding cantilever 5 is limited by the damping hinge 6. By installing a damping hinge with adjustable torque value at the hinge of the second sliding cantilever, the stability of the window opening angle can be enhanced by adjusting the torque value of the damping hinge.

As shown in FIG. 4 , the damping hinge 6 includes an upper rotating portion 61 and a lower connecting portion 62 . The rotating portion 61 is rotationally connected to the second sliding cantilever 5 , and the connecting portion 62 is slidingly connected to the second sliding groove 12 .

Among them, the damping hinge is a commonly used mechanical device that mainly controls the movement through the internal damping structure. Its working principle can be simply summarized as follows: during the rotation of the damping hinge, the movement speed and angle of the damping hinge are controlled by specially designed friction and damping forces. The damping hinge usually consists of two main parts: one is the damping hinge itself, and the other is its internal damping structure. Among them, the damping hinge usually consists of two interconnected and rotatable parts, which are connected by an axis, and the damping structure is located inside the damping hinge.

Specifically, the upper end of the damping hinge is connected to the No. 2 sliding cantilever, and the lower end is connected to the No. 2 slide groove on the base. The damping hinge can drive the No. 2 sliding cantilever to move in the No. 2 slide groove, and at the same time, the No. 2 sliding cantilever can rotate relatively around the rotating axis of the damping hinge.

A window comprises a window frame, a window sash and a hinge. The base of the hinge is connected to the window frame. The base 1 is fastened to a window frame groove through a first locking hole 11 and a second locking hole 14.

Specifically, the first linkage cantilever 2 is installed in the lower frame of the window frame. As shown in FIG3, the chain is connected to the window frame through the column 41 when it is in the closed state. The column of the first sliding cantilever is connected to the first linkage cantilever, and the extra part of the upper part of the column is connected to the lock block installed on the side frame of the window. When in use, the hinge is installed in the window frame as a whole, which is convenient for driving the window to move when opening and closing, so as to achieve cleaning of the blind corners.

As shown in Figure 8, when the utility model is in normal use, sliding cantilever No. 1 is in a fixed state and can only be rotated by the circular slider at the bottom of the fastener. When the linkage cantilever No. 1 is pulled to move outward, the sliding cantilever No. 2 is first driven to move downward, and then the sliding cantilever No. 2 drives the sliding cantilever No. 2 to move along the No. 2 slide groove toward the direction of the No. 1 slide groove until it moves to the lower end of the No. 1 slide groove. The maximum opening angle of the linkage cantilever No. 1 is 180°. When the hinge needs to be closed, just pull it hard in the opposite direction.

As shown in FIG. 2 , the opening process of the utility model for window cleaning is as follows: when the window cleaning function is to be realized, it is first necessary to release the fixing state of the fasteners to realize the overall translation of the window, so that the distance between the window and the wall is increased, thereby facilitating cleaning the window from the opened gap.

The specific operation process is: first, twist the tightening part to loosen the tightening part and the threaded rod, continue to twist to move the threaded rod downward, until the circular slider is completely out of the countersunk slot, stop twisting, and the fastener can slide in the No. 1 slide slot. Then open the window to a certain angle according to the normal operation mentioned above. In the process of sliding the No. 2 sliding cantilever along the No. 2 slide slot, the No. 1 sliding cantilever is further driven to slide along the No. 1 slide slot. At this time, the No. 2 sliding cantilever and the No. 1 sliding cantilever slide in the same direction along the No. 2 slide slot and the No. 1 slide slot respectively, so that the window can maintain a certain distance on the base as a whole and move left and right after opening a certain angle. The distance from the wall can be increased during the sliding process. The gap left by the left and right movement of the cantilever assembly can facilitate people to clean some hard-to-clean dead corners of the window.

The utility model aims to provide a hinge for a window, so as to enhance the opening angle of the window, thereby ensuring the stability of the window angle, and further driving the window to open and close by moving the cantilever assembly left and right in the slide groove, so as to achieve the cleaning of the blind corner of the window.

The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also fall within the protection scope of the present invention.
