【Detailed ways】

The present invention will be further described below in conjunction with the accompanying drawings:

A heavy-duty exterior window sliding support hinge as shown in Figures 1 to 6, comprising a sliding groove 1, a short rod 2, a middle rod 3, a long rod 4 and a support arm 5. One end of the long rod 4 is connected to the sliding groove 1 Rotational connection, the other end is rotatably connected to the middle of the support arm 5. On the side of the connecting point of the long rod 4 and the sliding groove 1 on the sliding groove 1, two independently sliding first sliding blocks 6 are slidably connected in sequence And the second sliding block 7, wherein the first sliding block 6 is located between the second sliding block 7 and the connection point of the long rod 4 and the sliding groove 1, and one end of the short rod 2 is rotatably connected with the first sliding block 6 , The other end is rotatably connected with one end of the support arm 5, one end of the middle rod 3 is rotatably connected with the second slider 7, and the other end is rotatably connected with the long rod 4, and the rotational connection point is located between the long rod and the chute 1. Between the rotation connection point and the rotation connection point of the long rod and the support arm 5, the middle rod 3 crosses the short rod 2 and the middle rod is supported at the bottom of the short rod 2, and the middle rod 3 and the short rod 2 rotate at the intersection Connected, the short rod 2, the middle rod 3, the long rod 4, and the support arm 5 form a parallelogram 10 between the adjacent two rotationally connected nodes, which changes as the sliding hinge opens and closes.

The rotational connection between the above-mentioned different components is realized by hinged connection with rivets.

Through the cooperation of the double-slider structure of the first slider 6 and the second slider 7, the short rod 2 and the middle rod 3 are crossed and then rotated and connected, so that the connection node of the short rod 2 and the first slider 6, the middle rod 3 and the first The connecting node of the two sliding blocks 7, the connecting node of the short rod 2 and the middle rod 3 form a triangle with the same waist and variable length and shortening of the bottom side, and the parallelogram 10 realizes the heavy-duty external window sliding support The hinge is opened and closed to realize the opening and closing of the window sash. The new link connection structure is adopted. Because the short rod 2 and the middle rod 3 are cross-connected, and the middle rod 3 supports the short rod 2 from the middle, it is shortened. The length of the suspended arm from the point of force to the support point relatively reduces the torsion of the short rod 2 by the window sash, and at the same time makes the short rod 2 have two connection points and support points of the middle rod 3 and the first sliding block 6, and the rotation is dispersed. The force of the connection structure, such as the rivet rotation connection, can increase the service life of the rivet; the other can avoid the use of wrap angle and guiding head structure, simplifying the structure of the chute 1 and the support arm 5.

The middle rod 3 is provided with a relief groove 31 for avoiding the rotational connection point of the short rod 2 and the first sliding block 6 when closed, and connects the rotational connection point of the short rod 2 and the first sliding block 6 It coincides with the sliding track of the rotating connection point of the middle rod 3 and the second slider 7, so that after closing, the chute 1, the short rod 2, the middle rod 3, the long rod 4 and the support arm 5 are parallel and overlapped into a line shape , As shown in Figure 4, the window sash has good closing performance, which reduces the volume of the heavy-duty outer window sliding support hinge after it is closed.

As shown in Figure 3, the chute 1 includes an L-shaped plate 13 composed of a vertical plate 11 and a horizontal plate 12. The upper end of the vertical plate 11 of the L-shaped plate 13 is provided with an inverted U-shaped slide rail 14 facing the horizontal plate 12 , The first slide 6 and the second slide 7 are attached to the horizontal board 12, and the first slide 6 and the second slide 7 are provided with a slide rail 14 inserted in the slide rail 14 to slide A mating sliding table 61 is provided between the horizontal plate 12 and the sliding rail 14 for the sliding of the first sliding block 6 and the second sliding block 7 and restricting the first sliding block 6 and the second sliding block 7 to the horizontal plate 12 And the sliding port 15 between the slide rail 14. The connecting structure of the sliding groove 1 and the first sliding block 6 and the second sliding block 7 is simple, only the first sliding block 6 and the second sliding block 7 are opposed to the horizontal plate 12, and the sliding table 61 corresponds to the sliding rail 14 from the sliding One end of the slot 1 can be inserted, and the connection is convenient and fast. At the same time, the inverted U-shaped slide rail 14 can prevent dust and garbage from accumulating. When the L-shaped plate 13 deposits dust and other garbage, it only needs to sweep the garbage horizontally along the horizontal board 12. However, it is easy to clean, and solves the problem of difficulty in cleaning up garbage caused by the traditional chute of the concave structure.

Below the sliding groove 1 is provided a lock piece 8 that can be locked in the channel 101 of the aluminum profile of the window frame 100 when rotating, and the lock piece 8 is connected to the sliding groove 1 by a hexagon socket screw 81. The lock piece 8 follows the rotation of the hexagon socket screw 81, and the sliding groove 1 is provided with a screw hole 16 for locking the sliding groove 1 on the window frame 100. Since the window frame is usually made of aluminum profile and has a channel 101, when the heavy-duty external window sliding support hinge is installed on the window frame, it is only necessary to turn the hexagon socket screw 81 to rotate the lock plate 8 in the channel 101 Inside, you can lock the heavy-duty outer window sliding support hinge on the window frame, and then insert the screw from the screw hole 16 to connect with the window frame, and fix the heavy-duty outer window sliding support hinge lock at the set position. Disassembly and assembly are quick and convenient, and solve the problem of the traditional complicated installation structure with multiple screw holes and multiple screw locking.

A reinforcing piece 9 for supporting the long rod 4 is fixed on the chute 1 at the connection between the long rod 4 and the chute 1, and the reinforcing piece 9 is located between the long rod 4 and the chute 1 and rotates with the long rod 4 Connect, avoid punching and drawing the corresponding structure on the chute 1 to directly pad up the long rod 4. Due to the punched and stretched structure, the higher the tensile boss, the weaker the structural strength, and the long rod 4 is replaced by the reinforcing sheet 9. The pads are raised to a corresponding height to strengthen the structural strength of the connection between the long rod 4 and the chute 1. The long rod 4 is jointly connected by the chute 1 and the reinforcing piece 9 to bear the force together, and the connection strength is good, which can meet the performance upgrade of the window sash. Increasing weight requirements.

Furthermore, as shown in Figure 6, when the chute 1 is installed in the channel 101, the chute 1 is usually supported from the left and right sides of the chute 1. The channel 101 avoids the middle area of the bottom of the chute 1. It is empty so that the structure where screws or rivets protrude from the bottom of the chute 1, and the connection point between the long rod 4 and the chute 1 is in the suspended middle area of the chute 1, and the structure of the suspended middle area of the chute 1 The strength is relatively weak. Under the long-term pressure of the heavy outer window, the sliding groove 1 and the reinforcing piece 9 are prone to deformation, and accelerate the rotation and wear of the long rod 4 at the connection. For this reason, the reinforcing piece 9 is provided with a slave One end of the chute 1 protrudes from a positioning support piece 91 below the bottom of the chute 1. The positioning support piece 91 is used to extend into the channel 101 of the window frame 100 and support it on the bottom of the channel 101 of the window frame 100, forming a middle Support to prevent the chute 1 and the reinforcing sheet 9 from being deformed when they are seated, and the width of the positioning support sheet 91 corresponds to the width of the channel opening. When the positioning support sheet 91 is inserted into the channel 101 from the channel opening, the positioning The supporting piece 91 cooperates with the left and right sides of the channel 101 to locate the left and right positions of the sliding channel 1 on the channel 101.

As shown in Figure 1, the reinforcing sheet 9 is stamped and formed with a convex hull 92 from the bottom to the top. The sliding groove 1 is provided with a protruding support boss 17 supported at the bottom of the convex hull 92, and the long rod 4 passes through A rivet is rotatably connected with the convex hull 92 and the supporting boss 17 at the same time. Since a certain height is padded by the reinforcing sheet 9, the convex hull 92 and the supporting boss 17 only need to be stretched to a small height, and the structural strength is good. However, the double structure and long length of the convex hull 92 and the supporting boss 17 The rod 4 is hinged by a rivet, and the connection strength is good, the contact area of the rotating surface of the rivet is increased, and the service life of the rivet at the connection is improved. The long rod 4 is cushioned and separated from the top surface of the reinforcing sheet 9 by the convex hull 92 to prevent the long rod 4 from interfering with the reinforcing sheet 9 during rotation and affecting the rotation; and the top surface of the long rod 4 and the reinforcing sheet 9 have a certain degree of The gap allows the long rod 4 to have a certain amount of deformation without affecting the normal use of the sliding hinge.

The sliding support hinge of the heavy-duty external opening window has a simple structure, good structural strength, can be applied to heavy-duty external opening windows, has good safety performance in use, and is easy to install.
