The slide 6 is a fitting that slides along the chute 1 with a damping effect and a positioning function. In the structure, the slide block 6, the stress arm 4, the bearing arm 2, the guide arm 3 and the auxiliary arm 5 form a five-link transmission component.
In addition, the riveting holes at the two hinged positions on the force receiving arm 4 are designed concentrically (namely, the connecting line of the two riveting holes is in the same direction with the axial direction of the force receiving arm), so that in order to avoid over rotation when the sliding support is closed, the wrap angle 7 needs to be arranged at the end part of the sliding chute 1, and the processing cost of the product installation wrap angle 7 is increased.
When the sliding support realizes the supporting effect, most of the weight of the door and window is borne on the stress arm 4 because only one stress arm 4 is provided, and the stress arm 4 slides along with the sliding block 6 in the opening and closing processes of the door and window, so that the bearing capacity of the sliding support structure is very low.
As shown in fig. 3 to 6, in order to enhance the bearing capacity of the sliding support for building doors and windows and reduce the production and processing costs of the sliding support, the utility model provides a high-bearing and low-cost sliding support for building doors and windows, which comprises a bottom rail 10 fixedly connected with a building door and window frame, a bearing arm 20 fixedly connected with a building door and window, a stress arm arranged between the bottom rail 10 and the bearing arm 20, and a guide arm 30. The bottom rail 10 is used for providing a supporting base of the whole sliding support structure, the supporting arm 20 is used for providing a base for fixing the door and window, the guide arm 30 is used for providing guidance for opening and closing the door and window, and the stress arm is used for bearing the door and window.
The bottom rail 10 of the present invention is made of aluminum alloy. In the traditional sliding support structure, the sliding chute is made of stainless steel, and needs to be formed in a punching mode in the machining process, so that the raw material cost is high, and the machining cost and the machining difficulty are high; the aluminum alloy material of the utility model not only reduces the weight of the whole sliding support structure and the cost of raw materials, but also can be formed by extrusion, and has smaller processing difficulty and lower processing cost. In addition, other alloy components can be added into the aluminum alloy material to increase the yield strength and hardness of the sliding support structure, but the cost is lower than that of the traditional stainless steel material, the processing difficulty is lower than that of the stainless steel, and the aluminum alloy components added into the aluminum alloy material and the corresponding proportion are not specifically limited in the application and can be properly adjusted according to specific needs.
The surface of the bottom rail 10 is provided with a bottom groove 11, and the bottom groove 11 provides a sliding track for the building door and window. Specifically, a slider 60 sliding along the bottom groove is arranged in the bottom groove 11, and the slider 60 has a damping effect and a positioning function (the opening angle of the sliding support structure can be adjusted). The slider 60 is hinged to the inner end of the guide arm 30 and the outer end of the guide arm 30 is hinged to one end of the support arm 20. In the process that the sliding block 60 slides along the bottom groove 11, the guide arm 30 is sequentially driven to be gradually opened or closed, and then the supporting arm 20 and the building door and window are driven to be opened or closed. In the sliding support structure of the traditional building door and window, the end part of the inner side of the guide arm is fixed, the outer side of the guide arm is used for opening or closing the door and window, and the window and window have a smaller range after being completely opened, while the guide arm 30 in the utility model is used as a movable part and can move along with the position when being opened at an angle, so that the window and window has a larger range after being opened.
As shown in fig. 3, in the present embodiment, the cross section of the bottom groove 11 is in a concave shape, the cross section of the slider 60 is in an i shape, and a bottom cross beam of the slider 60 is sleeved inside the bottom groove 11, so that the slider 60 cannot fall off from the bottom groove 11, and the sliding is more convenient. Preferably, the bottom slot 11 extends from one end of the bottom rail 10 to the other end, so that the slider 60 is easier to install during assembly.
In addition, the stress arm in the utility model comprises a first stress arm 40 and a second stress arm 50, the other end of the bottom rail 10 is hinged with the first stress arm 40 and the second stress arm 50, and the other end of the first stress arm 40 and the other end of the second stress arm 50 are hinged with the other end of the bearing arm 20, so that the bearing arm 20, the first stress arm 40, the bottom rail 10 and the second stress arm 50 are sequentially connected to form a four-bar linkage structure. The first force-bearing arm 40 and the second force-bearing arm 50 simultaneously support the support arm 20, and compared with a traditional sliding support structure with one force-bearing arm, the bearing capacity of the sliding support structure is larger; meanwhile, the inner sides of the first force receiving arm 40 and the second force receiving arm 50 are hinged to the bottom rail 10, and the positions of the first force receiving arm 40 and the second force receiving arm 50 cannot move along with the opening and closing of the door and window, so that the bearing capacity of the two force receiving arms is further improved.
The length of the first force-receiving arm 40 is less than the length of the second force-receiving arm 50, and the length of the second force-receiving arm 50 is less than the length of the guide arm 30. The hinged position of the second force-bearing arm 50 and the bottom rail 10 is positioned between the hinged position of the first force-bearing arm 40 and the bottom rail 10 and the sliding block 60, and the hinged position of the second force-bearing arm 50 and the supporting arm 20 is positioned between the hinged position of the first force-bearing arm 40 and the supporting arm 20 and the hinged position of the guide arm 30 and the supporting arm 20. When the sliding support for the building door and window is in a fully opened state, the first force receiving arm 40 and the bearing arm 20 (the door and window) form an angle similar to a straight line, the second force receiving arm 50 and the door and window form a small triangular support, and the guide arm 30 and the door and window form a large triangular support.
As shown in fig. 1 and 2, in the conventional sliding support structure for building doors and windows, the supporting arm 2 and the force-bearing arm 4 are both regular long strips. In order to avoid the phenomenon that the bearing arm 2 is out of position when closed, the end part of the sliding groove 1 is additionally provided with a wrap angle 7, so that the bearing arm 2 falls into the wrap angle 7 after being closed. In the utility model, the convex limiting angle 41 is arranged on the outer side of the first force receiving arm 40, so that when the sliding support for the building door and window is closed, the limiting angle 41 is abutted against the limiting edge of the bottom rail 10, an acute included angle is formed between the edge line of the limiting angle 41 and the connecting line of two hinged positions of the first force receiving arm 40, at the moment, the door and window is closed, but because the limiting angle 41 is abutted against the limiting edge in preference to the bearing arm 20 in the closing process, the bearing arm 20 cannot form an 'offside' state when the sliding support is completely closed, the structure omits the wrap angle design of the traditional sliding support, the processing cost of a product is saved, and the product structure is more stable.
In order to match with the limit design, in the utility model, relative to the hinged position of the second force receiving arm 50 and the bottom rail 10, the hinged position of the first force receiving arm 40 and the bottom rail 10 is closer to the limit edge of the bottom rail 10, so that when the sliding support for the building door and window is in a completely closed state, the bearing arm 20, the second force receiving arm 50 and the guide arm 30 are all positioned on the same straight line, and an acute angle is formed between the connecting line of the two hinged positions of the first force receiving arm 40 and the bearing arm 20.
Specifically, one end of the second force-receiving arm 50 is hinged to the bottom groove 11, the upper side of the bottom rail 10 is provided with a reinforcing wall 12, and one end of the first force-receiving arm 40 is hinged to the reinforcing wall 12.
Preferably, the support arm 20 is provided with a clamping block 70 for fixing the side of the door window, and the building door window is further fixed by the clamping block 70. In this embodiment, the lower end of the clamping block 70 is connected to the supporting arm 20 through the supporting column 71, and the supporting column 71 is coaxial with the hinge position of the first force receiving arm 40 on the supporting arm 20, so as to further ensure the structural stability of the supporting arm 20.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the utility model as defined in the appended claims.
The utility model is described above with reference to the accompanying drawings, which are illustrative, and it is obvious that the implementation of the utility model is not limited in the above manner, and it is within the scope of the utility model to adopt various modifications of the inventive method concept and technical solution, or to apply the inventive concept and technical solution to other fields without modification.
