[0001] This utility model relates to the technical field of cabinet door lifting support mechanism, specifically, a lifting door support rod. Background Technology

[0002] In the common upward-opening door structure of cabinet doors, there is a buffering effect during the opening and closing process. The buffering structure is mostly based on the upward-opening door support rod structure. In the existing upward-opening door support rod structure, gas struts or springs are basically used. Gas struts are more expensive than springs, so support rods with spring structures are the more widely used products in the market.

[0003] However, in the existing spring support rod structure, the hinge structure for adjusting the spring buffer force is relatively complex, which makes the assembly of the entire lift-up door support rod troublesome, difficult, and costly. Moreover, the fixed seat installed inside the cabinet is usually directly installed on the main shell, which can easily lead to loosening between the main shell and the fixed seat, affecting the service life.

Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Combination Figures 1 to 5 The illustrated top-hinged door support rod includes a housing 1. A fixing seat 7 is inserted into one side of the housing 1. A spring 11 is installed inside the housing 1. An adjusting bolt 10 passes through one end of the housing 1 near the fixing seat 7, pressing the adjusting bolt 10 against one end of the spring 11. A swingable rocker arm 15 is installed at the other end of the housing 1. A slider 13 is engaged with one end of the rocker arm 15 near the spring 11, and the slider 13 abuts against the other end of the spring 11. A nut seat 8 is hinged to one side of the fixing seat 7, inserted into the housing 1, and the adjusting bolt 10 is threadedly connected to the nut seat 8, so that the fixing seat 7 is on the side of the housing 1. It is swingable; in this embodiment, the nut seat 8 is inserted into the housing 1 and locked onto the nut seat 8 by the adjusting bolt 10, so that the fixed seat 7 is fixed on the side of the housing 1, so that the fixed seat 7 can swing on the nut seat 8 to install in the cabinet. At the same time, the adjusting bolt 10 can abut against the spring 11, thereby adjusting the compression degree of the spring 11, thereby adjusting the pressure of the spring 11 on the slider 13, so as to achieve the swing buffering effect of the rocker arm 15. The whole structure is relatively simpler and more compact, easier to assemble, and easier to assemble, thereby reducing assembly costs. Moreover, the fixed seat 7 is more robust and has a longer service life.

[0020] It is worth noting that the mounting base 7 in this embodiment has a mounting hole, and the outer wall of the nut seat 8 is provided with a hinge shaft 9, which is hinged to the mounting base 7. This makes the nut seat 8 and the mounting base 7 vertically connected. After the nut seat 8 is inserted into the housing 1 for fixed installation, the mounting base 7 can rotate and swing through the hinge shaft 9, thereby facilitating the adjustment of the installation angle.

[0021] In this embodiment, a spring cavity 2 is provided inside the housing 1. An adjusting bolt cavity 3 is provided at one end of the spring cavity 2. A nut cavity 4 is provided between the spring cavity 2 and the adjusting bolt cavity 3. An opening for inserting a nut seat 8 is provided on one side of the nut cavity 4.
