Description

Technical Field

[0001] The invention relates to the technical field of door and window hardware, in particular to an adjustable auxiliary pull rod. Background Art

[0002] In modern buildings, the inward swing and underhang hardware system has been widely used due to its unique functionality and convenience. This hardware system allows doors and windows to open inwards and also to be opened under the hanging mode, meeting the ventilation, lighting and safety requirements in different scenarios. The diagonal rod is an important part of the inward swing and underhang hardware system. It plays an important role in mechanical support during the opening and closing of doors and windows. When the doors and windows are under the hanging, the diagonal rod can effectively share the weight of the window frame, ensure the stability of the hanging angle, and ensure the safety of the doors and windows when they are open.

[0003] Based on the above, the inventors have discovered the following problems: the existing auxiliary tie rods are usually designed with a single specification and cannot adapt to diagonal tie rods of various specifications. This results in the auxiliary tie rods and diagonal tie rods often not matching each other during the assembly and use of the hardware system. When the auxiliary tie rods cannot cooperate well with the diagonal tie rods, the mechanical properties of the entire hardware system will be affected.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an adjustable auxiliary pull rod is provided to achieve the purpose of having more practical value. Summary of the invention

[0005] The object of the present invention is to provide an adjustable auxiliary tie rod to solve the problems raised in the above background technology.

[0006] By adopting the above technical solution, the auxiliary tie rod can be easily adjusted to be suitable for inclined tie rods of various specifications.

[0007] In view of the above problems, the technical solution proposed by the present invention is: An adjustable auxiliary pull rod comprises a window frame connection mechanism, an adjustment mechanism and a window sash connection mechanism, the adjustment mechanism comprises a first connecting rod and a second connecting rod, a first mounting hole is formed at one end of the first connecting rod, a slide groove is formed at one side of the first mounting hole, a second mounting hole is formed at the other end of the first connecting rod, a first screw is connected to the internal thread of the second mounting hole, a third mounting hole is formed at one end of the second connecting rod, a plurality of adjustment holes are formed at one side of the third mounting hole, one end of the first screw is threadedly connected to one of the adjustment holes, a first rivet is inserted between the slide groove and the third mounting hole, and a first washer is sleeved on the first rivet and the first screw between the first connecting rod and the second connecting rod.

[0008] Furthermore, the window frame connection mechanism includes a frame base, and a fourth mounting hole is provided at the center of the upper end surface of the frame base.

[0009] The beneficial effect of adopting the above further solution is that by providing a frame base, it is convenient for users to install it at a suitable position on the window frame, and by providing a fourth mounting hole, it is convenient for users to install the first connecting rod.

[0010] Furthermore, a spring sheet is provided at the bottom end of the fourth mounting hole, and a second gasket is provided at the upper end of the first mounting hole.

[0011] The beneficial effect of adopting the above further scheme is that by installing the spring sheet, when the first connecting rod is retracted into the frame base, its two ends can be used to support the first connecting rod, thereby preventing it from shaking inside the frame base. By installing the second gasket, the wear between the first connecting rod and the spring sheet can be reduced.

[0012] Furthermore, the centers of the first mounting hole, the second washer, the spring sheet and the fourth mounting hole are located on the same axis, and a second rivet is inserted between the first mounting hole, the second washer, the spring sheet and the fourth mounting hole.

[0013] The beneficial effect of adopting the above further solution is that by locating the centers of the first mounting hole, the second washer, the spring sheet and the fourth mounting hole on the same axis, it is convenient for the user to insert the second rivet to install it and to rotate the first connecting rod.

[0014] Furthermore, a pair of through holes is opened on one side of the frame base, and the interiors of the through holes are both threadedly connected with second fixing screws.

[0015] The beneficial effect of adopting the above further solution is that by providing a through hole and threading the second screw inside the through hole, it is convenient for the user to fix the frame base and the window frame using the second screw.

[0016] Furthermore, the window sash connecting mechanism includes a sash connecting rod, a limiting groove is provided at the upper end of the sash connecting rod, and an opening buckle is installed at the bottom end of the sash connecting rod located in the limiting groove.

[0017] The beneficial effect of adopting the above further scheme is that by setting the sash connecting rod, it is convenient for the user to install it at the appropriate position on the window sash, by installing the limit groove, it is convenient for the third rivet to slide, and by installing the opening buckle, it is convenient to lock the third rivet.

[0018] Furthermore, a fifth mounting hole is formed at the other end of the second connecting rod, and a third rivet is disposed inside the fifth mounting hole.

[0019] The beneficial effect of adopting the above further solution is that, by arranging the third rivet inside the fifth mounting hole, it is convenient to install and connect the second connecting rod with the limiting groove on the fan connecting rod.

[0020] Furthermore, the bottom end of the third rivet is slidably connected to the limiting groove, and the bottom end of the third rivet is clamped to the inner side of the opening buckle.

[0021] The beneficial effect of adopting the above further scheme is that by slidingly connecting the bottom end of the third rivet with the limit groove, the window sash will not cause movement interference with the second connecting rod when closing and opening. By connecting the bottom end of the third rivet with the opening buckle, when the window sash is opened to the appropriate position, the third rivet slides to the inside of the opening buckle and locks with it, thereby improving the stability and safety of the window sash after it is unfolded.

[0022] The beneficial effects of the present invention are as follows: an adjustable auxiliary pull rod is obtained through the above-mentioned design of the present invention. The adjustable auxiliary pull rod is formed by opening a slide groove on the first connecting rod, and opening a second mounting hole at one end thereof, opening a third mounting hole at one end of the second connecting rod, and opening a plurality of adjustment holes on the second connecting rod. The user inserts the first rivet between the slide groove and the third mounting hole so that the second connecting rod can slide along the slide groove, thereby adjusting the length of the second connecting rod. The second connecting rod can be fixed by connecting the first screw with the internal thread of the third mounting hole so that it is threadedly connected with one of the adjustment holes. The second connecting rod located at different positions can be fixed by threading the first screw with different adjustment holes, thereby facilitating the user to adjust and fix it. The wear between the first connecting rod and the second connecting rod can be reduced by installing the first washer, thereby increasing the service life of both. BRIEF DESCRIPTION OF THE DRAWINGS
