Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, and specifically, to a door and window load-bearing device. Background Art

[0002] Modern doors and windows are usually in the form that the sides of the door and window main body are hinged to the sides of the door and window frame. When opening the door, it is pulled open in a hinged form. In this case, the weight of the door and window main body all falls on the hinge where the two are hinged, which requires high strength of the hinge. And now, in places such as sunrooms, doors and windows with relatively large weights will be used, and the supporting force of conventional hinges is not enough. If invisible hinges installed above and below the door and window are used, it will be even more difficult to support. Content of the Utility Model

[0003] In summary, to overcome the deficiencies of the prior art, the utility model provides a door and window load-bearing device that can share a part of the weight of the door and window main body.

[0004] To achieve the above object, the utility model provides the following technical solution: A door and window load-bearing device includes a first connecting member, a connecting rod, and a second connecting member. The first connecting member and the second connecting member are respectively connected to the side of the door and window frame and the door and window main body. One end of the connecting rod is hinged to the first connecting member and the other end is movably connected to the second connecting member.

[0005] With such a setting, during use, the first connecting member and the second connecting member are respectively installed at corresponding positions on the sides of the door and window frame and the door and window main body. Usually, grooves are provided on the installation sides, and the two connecting blocks are arranged in the grooves, so that the function can be realized without affecting the closing and opening of the door and window. After all parts are installed, the second connecting member installed on the door and window main body will conduct the weight of the door and window main body to the first connecting member through the connecting rod. In this way, the door and window main body will be suspended by the connecting rod, sharing the pressure on the hinge and increasing the load-bearing capacity of the door and window. When the door and window are fully opened or fully closed, the connecting rod will just be in a state of being connected to the second connecting member. During the process of opening and closing, the connecting rod will be swung on the first connecting member, and it will slightly lift up during the swinging process. The time of the opening and closing process is short, and the impact on the overall strength is small. The installation positions of the first connecting member and the second connecting member can also be reversed, with the second connecting member installed above the door and window frame and the first connecting member installed below the door and window frame. In this way, the load-bearing effect can also be achieved, and the number of load-bearing devices can be increased according to needs.

[0006] Further, it further includes a transmission rod. The first connecting member is provided with a first strip-shaped hole, the hinge shaft of the connecting rod and the first connecting member is located in the first strip-shaped hole, and both ends of the transmission rod are respectively hinged to the connecting rod and the first connecting member.

[0007] With such a setting, the transmission rod can pull the connecting rod to increase the stability of the connecting rod. After being connected to the transmission rod, one end of the connecting rod will hinge and slide in the first strip-shaped hole, reducing the displacement of the end of the connecting rod connected to the second connecting member in the vertical direction during the swinging process, keeping it as much as possible on the same horizontal plane, and making the connection more stable.

[0008] Furthermore, the transmission rod is located between the connecting rod and the first connecting member, and a support gasket is provided at the hinge position of the connecting rod and the first connecting member.

[0009] With such a setting, the connecting rod that will deform when opening and closing the door or window is located outside. During its deformation process, the influence on the transmission rod is small. Even if the transmission rod deforms, when the door or window is fully opened or closed, the connecting rod located outside will press it down to make it recover.

[0010] Furthermore, on the side of the second connecting member facing the first connecting member, there is an activity hole. The connecting rod passes through the activity hole, and at one end of the connecting rod facing the second connecting member, there is a connecting block larger than the activity hole.

[0011] With such a setting, after the connecting rod passes through the activity hole, it will be buckled on the second connecting member by relying on the connecting block. In this way, the weight of the door or window main body will be suspended at the position of the connecting block by relying on the second connecting member. And after setting the activity hole, the connecting rod can freely rotate in the activity hole when opening and closing the door or window. The structure is simple and the installation is convenient.

[0012] Furthermore, the connecting block is a T-shaped pin inserted into the end of the connecting rod and having an interference fit with it. The rod part of the connecting block is smaller than the activity hole, and the head part of the connecting block is larger than the activity hole.

[0013] With such a setting, a hole adapted to the pin will be provided at the end of the connecting rod. During installation, only need to align this hole with the activity hole and then knock in the pin to complete the installation at this position. The installation is convenient. After the installation is completed, the rod of the pin can move in the activity hole, while the head of the pin will be stuck below. After connection, it can also be welded to increase the connection strength.

[0014] Furthermore, on the side of the activity hole of the second connecting member facing the connecting block, there is a connecting plate, and the activity hole penetrates through the connecting plate.

[0015] With such a setting, the connecting plate can be made of a material with higher hardness. In this way, when the connecting block is suspended at this position, the friction with it will not cause damage, and the overall strength of the second connecting member is higher. The connecting plate can be connected to the second connecting member by means of plugging.

[0016] Further, the second connecting member includes a mounting member, a movable member, and an adjusting member. The movable member is slidably connected to the mounting member. The movable hole is located on the movable member. The mounting member is connected to the side of the door and window body. The adjusting member is used to control the position of the movable member on the mounting member.

[0017] With such a setting, the mounting member can be installed on the door and window by passing multiple bolts through it. Then, the position of the movable member on the mounting member can be changed by using the adjusting member, so as to change the tightness between the connecting rod and the movable member.

[0018] Further, a sliding groove is provided on one side of the movable member facing the mounting member, and a sliding head adapted to the sliding groove is provided on the mounting member.

[0019] With such a setting, the movable member will slide on the mounting member in a form that the sliding groove sleeves outside the sliding head, which is more stable.

[0020] Further, an adjusting groove is provided on the mounting member. An adjusting block is provided at the position of the movable member in the adjusting groove. The adjusting member is a bolt that penetrates the adjusting block and is threadedly connected to it. The adjusting member is rotationally connected to the mounting member around the axis of the adjusting member on the mounting member.

[0021] With such a setting, the adjusting block will be inserted into the adjusting groove. Then, when installing, the adjusting block of the selected bolt is inserted and screwed onto the adjusting block. When screwing, since the adjusting member is rotationally connected to the mounting member, its rotation will not be affected and it can be screwed in and out at will. However, its axial sliding is restricted. Therefore, the mounting member will be driven to move together by the head of the bolt, so as to achieve the adjusting effect, and the operation is simple.

[0022] Further, a fixing groove is provided on the mounting member. The fixing groove penetrates through one end of the mounting member facing away from the adjusting member. The fixing groove is communicated with the adjusting groove. A connecting groove adapted to the bolt head of the adjusting member is provided in the fixing groove.

[0023] With such a setting, the bolt will be inserted from the position of the fixing groove, its screw head is placed in the connecting groove, and the screw rod part enters the adjusting groove to be connected to the adjusting block. After installation, the connecting groove will restrict the bolt head, restricting its axial sliding while not affecting its rotation. BRIEF DESCRIPTION OF THE DRAWINGS
