Detailed implementation manners
[0029] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.
[0030] The embodiments of the present invention provide a built-in hinge with a large opening angle. Please refer to Figures 1-3, including a first mounting member 10, a second mounting member 20 and a linkage assembly 30; the first mounting member 10 includes a main body 110 and a sliding member 120, and the sliding member 120 moves on the main body 110; one end of the second mounting member 20 is hinged to the sliding member 120, and a plurality of mounting holes 230 are provided on the second mounting member 20; the linkage assembly 30 is respectively connected to the first mounting member 10 and the second mounting member 20, and the second mounting member 20 rotates relative to the first mounting member 10 through the linkage assembly 30.
[0031] Using the built-in hinge with a large opening angle of this embodiment, the first mounting member 10 is used to be fixed on the windowsill, and the second mounting member 20 is used to install the window. The second mounting member 20 rotates relative to the first mounting member 10 through the linkage assembly 30, thereby opening the window. Since one end of the second mounting member 20 is connected to the sliding member 120, and the sliding member 120 moves on the main body 110. At this time, the included angle between the linkage assembly 30 and the first mounting member 10 is always an acute angle. And according to the geometric properties of the triangle, at this time, angle a = b + c, and c is approximately equal to the opening angle of the hinge in the prior art. Implementing the built-in hinge with a large opening angle in the present invention can realize a hinge that can be unfolded at a larger angle.
[0032] In one embodiment, a plurality of mounting holes 230 are provided on the second mounting member 20.
[0033] The plurality of mounting holes 230 on the second mounting member 20 are generally used to install the window, and the window is unfolded by driving the edge of the window to move.
[0034] The first mounting member 10, the second mounting member 20 and the linkage assembly 30 together form a triangle. A triangle is a stable geometric figure, which can ensure the positioning of the window after it is opened and avoid shaking. In this triangle, the base changes as the sliding member 120 slides.
[0035] In one embodiment, a chute 1110 is provided on the main body 110, and the sliding member 120 is movably arranged in the chute 1110 so that the sliding member 120 moves along the length direction of the main body 110.
[0036] Normally, the sliding member 120 can be wrapped around the main body 110. Optimally, a chute 1110 is still provided on the main body 110, so that the movement of the sliding member 120 is not interfered by external things. That is, when installing, there is no need to consider deliberately avoiding obstacles on the movement path of the sliding member 120.
[0037] In one embodiment, please refer to Figure 1 , the linkage assembly 30 includes a connecting rod 310 and a support rod 320. The connecting rod 310 is respectively hinged to the first mounting member 10 and the second mounting member 20, and the support rod 320 is respectively hinged to the sliding member 120 and the connecting rod 310.
[0038] The function of the connecting rod 310 is to link the first mounting member 10 and the second mounting member 20, and the function of the support rod 320 is to strengthen the support. The support rod 320, the connecting rod 310 and the first mounting member 10 form a triangle, thereby increasing the stability of the hinge to resist strong wind and heavy rain weather.
[0039] In one embodiment, a dust-proof member 330 is further provided on the support rod 320. The dust-proof member 330 is sleeved on the support rod 320 and can move along the length direction of the support rod 320.
[0040] The dust-proof member 330 is movably arranged on the support rod 320. By moving the dust-proof member 330 back and forth, dust can be removed. On the other hand, the strength of the support rod 320 can also be enhanced.
[0041] In one embodiment, the sliding member 120 is formed by nesting a support plate 1210 and an anti-slip pad 1220, and the anti-slip pad 1220 faces the main body 110.
[0042] The sliding of the sliding member 120 in the sliding groove 1110 should not be too smooth, otherwise the hinge is likely to be shaken. By integrating the support plate 1210 and the anti-slip pad 1220 and arranging the anti-slip pad 1220 facing the main body 110, it can ensure that the sliding member 120 has a certain damping effect while maintaining a certain strength.
[0043] The friction between the anti-slip pad 1220 and the main body 110 is relatively large, which can not only play a damping effect, but also reduce the wear of the sliding groove 1110.
[0044] In one embodiment, please refer to Figure 4 , the sliding member 120 is provided with a clamping portion 1230, and the clamping portion 1230 is clamped with the sliding groove 1110 to prevent the sliding member 120 from separating from the first mounting member 10.
[0045] The clamping portion 1230 is snapped into the sliding groove 1110, so that the sliding member 120 can only move along the length direction of the sliding groove 1110 and cannot move away from the main body 110. Such a setting can prevent the sliding groove 1110 and the sliding member 120 from separating, resulting in the disassembly of the hinge.
[0046] In one embodiment, the main body 110 has at least one end with an opening 130 to facilitate the sliding member 120 to enter the sliding groove 1110 from the opening 130.
[0047] The sliding member 120 needs to be assembled with the main body 110. The clamping portion 1230 of the sliding member 120 enters the sliding groove 1110 from the opening 130, thereby realizing the mutual locking of the sliding member 120 and the main body 110. Among them, the main body 110 and the sliding member 120 are generally formed by bending profiles, preferably aluminum profiles.
[0048] More specifically, the second mounting member 20 and the linkage assembly 30 are also all formed by bending and shaping aluminum profiles.
[0049] In one embodiment, the second mounting member 20 includes a first section 210 and a second section 220 that are hinged to each other. The first section 210 is hinged to the first mounting member 10, and the second section 220 is hinged to the linkage assembly 30.
[0050] In this embodiment, it is mainly to expand the unfolding range of the hinge as much as possible. Since the second mounting member 20 needs to be stored and stacked with the first mounting member 10. Therefore, the length of the second mounting member 20 cannot be longer than the length of the first mounting member 10. Otherwise, if it cannot be stored, the second mounting member 20 will extend beyond the first mounting member 10.
[0051] Specifically, the distance from the sliding member 120 to one end of the first mounting member 10 should always be greater than the length of the second mounting member 20 after being stored.
[0052] By the first section 210 and the second section 220 that are hinged to each other, it can meet the requirement that it does not extend beyond the length of the first mounting member 10 after being stored, and at the same time, the unfolding angle a of the hinge can be made as large as possible.
[0053] It should be noted that since the second mounting member 20 is divided into the first section 210 and the second section 220, its supporting stability is not enough. Therefore, the support rod 320 in the linkage assembly 30 can play a role in strengthening the support more. In the unfolded state of the entire hinge, there must be a relatively stable triangle.
[0054] In one embodiment, the first mounting member 10 further includes a first limiting member 140. The second section 220 is provided with a limiting portion 2210, and the limiting portion 2210 cooperates with the first limiting member 140 to prevent the second mounting member 20 from rotating to the other side of the first mounting member 10.
[0055] When the hinge changes from the unfolded state to the stored state, the first section 210 and the second section 220 rotate relative to each other until they rotate 180 degrees and coincide. At this time, the limiting portion 2210 of the second section 220 abuts against the first limiting member 140, thereby preventing the second mounting member 20 from continuing to rotate.
[0056] In one embodiment, the first mounting member 10 further includes a second limiting member 150. The second limiting member 150 is disposed in the path of the sliding groove 1110 and cooperates with the first limiting member 140 to limit the sliding of the sliding member 120 between the first limiting member 140 and the second limiting member 150.
[0057] In the triangle formed by the first mounting member 10, the second mounting member 20, and the connecting rod 310, the base is formed by the first mounting member 10, and only the length of the base changes as the slider 120 slides. When the second mounting member 20 is completely perpendicular to the first mounting member 10, there is a dead point of motion, and it is very difficult to continue moving the slider 120 at this time. Therefore, the second limiting member 150 can prevent the slider 120 from entering the dead point.
[0058] In addition, as the slider 120 slides to the right, after the slider 120 passes the dead point, the end of the second mounting member 20 away from the first mounting member 10 will approach the first mounting member 10 instead, which results in a decrease in the opening degree of the window.
[0059] It should be noted that all components are connected by bolts. Specifically, after the slider 120 is installed into the chute 1110 from the notch, the second limiting member 150 and the first limiting member 140 are respectively fixed with two bolts to make it difficult for the slider 120 to slide out. Then, the connecting rod 310 is connected to the first mounting member 10 with a single bolt, and the slider 120 and the second mounting member 20 are connected with a single bolt. Immediately afterwards, the two ends of the support rod 320 are respectively hinged to the connecting rod 310 and the slider 120 with bolts. Finally, one end of the connecting rod 310 is hinged to the first mounting member 10 with a bolt.
[0060] The following describes an embodiment of the hinge of the present utility model from being retracted to being deployed as a whole.
[0061] 1. Push the window, driving the second mounting member 20 to rotate relative to the first mounting member 10, and the slider 120 starts to move to the left.
[0062] 2. The first section 210 and the second section 220 of the second mounting member 20 start to rotate relative to each other until there is no included angle between the first section 210 and the second section 220.
[0063] 3. The slider 120 abuts against the second limiting member 150. At this time, the doors and windows are in the maximum deployed state.
[0064] The process of the hinge from being deployed to being retracted is opposite to the above process.
