Description
Technical Field
The invention belongs to the technical field of sliding support hinges, and particularly relates to a sliding support hinge which is free of a sliding groove and easy to install.
Background
The sliding support hinge for the casement window is assembled by a sliding rail, a sliding block, a guide top angle and a plurality of support cantilevers: the sliding rail is an open-ended groove formed by bending a stainless steel sheet, the sliding block is assembled in the groove below the upper folded edge of the open-ended groove, and the short supporting cantilever and one end of the supporting cantilever are hinged to corresponding positions of the sliding block; one end of the long supporting cantilever is hinged to one end of the sliding rail, the middle of the long supporting cantilever is hinged to the other end of the supporting cantilever, the other end of the long supporting cantilever is hinged to the middle of the top supporting cantilever, and the head of the top supporting cantilever is hinged to the other end of the short supporting cantilever to form a connecting rod movement mechanism. The other end of the sliding rail is provided with a guide vertex angle which plays a role in guiding the opening and closing of the hinge. The sliding rail of the sliding support hinge and the top support cantilever are provided with mounting holes at corresponding positions, the sliding rail and the top support cantilever are respectively connected and fixed with the window frame and the window sash during mounting, when the window sash is pushed, the force is transmitted to the connecting rod motion mechanism by the top support cantilever mounted on the window sash, and the slide block can slide in the sliding rail, so that the motion mechanism moves under the action force, and the window sash can be opened and closed.
The weight of the window sash is supported and pressed on the short supporting cantilever and the long supporting cantilever through the top supporting cantilever, and the short supporting cantilever is stressed independently, while the long supporting cantilever is stressed jointly (because the middle part of the long supporting cantilever is hinged with one end of the supporting cantilever), the stress of the short supporting cantilever is larger than that of the supporting cantilever and that of the long supporting cantilever. The slider still needs to slide back and forth while bearing the pressure of the short supporting cantilever and the supporting cantilever, so that the stress condition is worse.
The commonly used sliding stay hinges have some disadvantages: 1. the bending change or the twisting of the sliding rail or the top supporting cantilever is caused by the stress change in the opening and closing process of the window sash, so that the mounting screw is gradually loosened, and the window sash falls off due to the fact that the window sash is separated from the top supporting cantilever or the sliding rail is separated from the window frame under the condition that the window is accidentally impacted because the screw is loosened or loses efficacy if the window is cared for in an unscheduled way after being used for a period of time. 2. After long-time use, the sliding block is deformed or broken under the condition that the window sash is impacted by external force due to the fact that bearing capacity of the sliding block is poor under the condition of long-time abrasion, the sliding block is separated from the sliding rail, the window sash cannot be opened or closed, and even the danger that the window sash falls possibly occurs. 3. For the sliding support hinge installed at the bottom end of the window sash, the short support cantilever is seriously bent downwards due to large stress, so that the head of the top support cantilever hinged with the short support cantilever is bent downwards, and one end of the window sash (connected with the top support cantilever) is drooped. And the sag of one end of the window sash enables the gap between the top end of the window sash and the window frame to be drawn downwards and expanded, so that the window is not closed tightly, and even the head of the top supporting cantilever of the sliding support hinge connected with the top end of the window sash is drawn downwards by the sagging window sash to be separated from the lower surface of the guide top angle. The sliding support hinge can not be opened or closed, so that the window sash can not be opened or closed. 4. The dust falling on the slide rail can block the sliding of the slide block after being accumulated for a period of time, so that the window sash is not smoothly opened or even cannot be opened or closed.
In view of the above, the present invention is particularly proposed.

When the short-support cantilever 3 bends downwards due to bearing the gravity of the window sash, the reinforcing pad 8 on the short-support cantilever 3 bends downwards, so that the lower sliding support rivet 9 is driven to move downwards. Because a certain gap is reserved between the step surface of the second-stage circular step 9-2 of the lower sliding support rivet 9 and the top surface of the top support cantilever 4, therefore, when the lower sliding support rivet 9 is driven to move downwards due to the downward bending of the short support cantilever 3 under the force, the top support cantilever 4 is not dragged to bend downwards until the step surface of the second-stage circular step 9-2 of the lower sliding support rivet 9 moves downwards and contacts with the top surface of the top support cantilever 4, and then the lower sliding support rivet 3 bends downwards along with the continuous downward bending of the short support cantilever 3, so that the droop of the window sash arranged on the top supporting cantilever 4 can be adjusted and relieved by adjusting the gap between the step surface of the second-stage circular step 9-2 and the top surface of the top supporting cantilever 4, and further prevent the end of the top supporting cantilever 4 from being pulled down by the drooping window sash to be separated from the guide top corner 1, so that the sliding support hinge can not be opened or closed to cause the window sash to be opened or closed.
Referring to fig. 1a, the end of the upper brace rivet 10 fitted between the end of the top bracket cantilever 4 and the reinforcing pad 8 is provided with a screw hole (as shown in fig. 8), and the locking/positioning block 11 can be locked by a screw 13 so as to prevent the locking/positioning block 11 from being separated from the upper brace rivet 10.
Further, referring to fig. 1a, the short supporting cantilever 3 is a thickened structure and is wrapped with a nylon sleeve pad 3-1 (as shown in fig. 3a-3 c), and a reinforcing pad 8 is arranged between the short supporting cantilever 3 and the top supporting cantilever 4 for reinforcing the bending resistance of the short supporting cantilever 3 and the top supporting cantilever 4, further reducing the sagging of one end of the window sash and increasing the bearing capacity of the sliding support hinge.
Besides the main characteristics, the invention can also be applied to various section bars, and the installation is convenient: as shown in fig. 1a-1C and fig. 2, the present invention can be used for K-channel profile and common channel profile, in addition to C-channel profile, when the frame connecting plate 2 of the original tertiary platform is replaced by the frame connecting plate of the common flat plate. When the anti-loosening/positioning block 11 is leaned against one side of a window sash, the top supporting cantilever 4 can be positioned and installed on the window sash, and then the frame connecting plate 2 can be installed on the window frame by leaning the guide top angle 1 against one side of the window frame. The position of the mounting hole does not need to be measured and calculated in advance, so that the installation is quick and convenient.
