DETAILED DESCRIPTION

[0020] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0021] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0022] like Figure 1 and Figure 2 As shown, a specific embodiment of the utility model provides a suspended hinge, which has a function of being able to be opened and closed arbitrarily and suspended, and can be applied to different furniture structures. Specifically, it includes a fixed end 100 and a movable end 200, and a connecting rod 300 mechanism is provided between the fixed end 100 and the movable end 200; the connecting rod 300 mechanism includes a connecting rod 300 and a first cantilever 400 arranged in an X structure and hinged to each other at a cross position, and the upper end of the connecting rod 300 is hinged to a second cantilever 500 parallel to the first cantilever 400, and the front ends of the first cantilever 400 and the second cantilever 500 are hinged to the edge of the movable end 200, and the first cantilever 300 is hinged to the movable end 200. The rear ends of the arm 400 and the connecting rod 300 are hinged to the fixed end 100, and one end of the connecting rod 300 hinged to the fixed end 100 is also provided with a supporting portion 310. A sliding plate 600 capable of horizontal sliding is provided in the fixed end 100, and a hydraulic cylinder 700 is installed on the sliding plate 600. The front end of the sliding plate 600 is abutted against the abutting portion 310. A damping lever 800 is provided at the rear end of the fixed plate corresponding to the sliding plate 600. One end of the damping lever 800 is abutted against the rear end of the sliding plate 600, and the other end is abutted against a damping slider 900 provided in the fixed end 100. The damping slider 900 is provided with a damping spring 1000 with adjustable damping.

[0023] like Figure 1 and Figure 2 As shown, through the above arrangement, the hinge structure provided in this embodiment uses the connecting rod 300 structure to install the movable end 200. When in use, the movable end 200 is installed on a structure that needs to be opened and closed, such as a cabinet door, and the fixed end 100 is installed on the cabinet body; the first cantilever 400, the second cantilever 500 and the connecting rod 300 of the connecting rod 300 mechanism constitute a four-link 300 structure, so that the movable end 200 can be rotated to any angle. In order to achieve hovering, the cantilever and the connecting rod 300 structure in this embodiment push the sliding plate 600 to move horizontally through the abutment portion 310 at the lower end of the connecting rod 300 during the rotation process. During the movement of the sliding plate 600 The damping lever 800 is rotated to drive the damping slider 900 to slide. Since the damping slider 900 is connected to the damping spring 1000 and the sliding plate 600 is provided with a hydraulic cylinder 700, when the resistance generated by the damping spring 1000 is balanced with the damping generated by the hydraulic cylinder 700, the movable end 200 can be suspended. Since the weights of different cabinet door structures are different, the hovering function can be achieved by adjusting the resistance of the damping spring 1000 according to the installation weight of the movable end 200 during use, thereby improving the use effect of different product installations. In actual use, the best use effect is within the opening and closing angle range of 20°-70°.

[0024] like Figure 1 and Figure 2 As shown, when the sliding plate 600 is in the initial position, the movable end 200 is located at the end of the fixed end 100 and is in a closed state. In order to ensure the stability of the cabinet door in a closed state when in use, this embodiment provides a positioning claw 320 on the outer side of the end where the connecting rod 300 and the fixed end 100 are hinged, and a positioning groove 610 for the positioning claw 320 to be inserted into the end of the sliding plate 600 close to the connecting rod 300. That is to say, when in the closed state, the positioning claw 320 can be stuck in the positioning groove to ensure stability, and when the connecting rod 300 rotates clockwise, the positioning claw 320 exits the positioning groove to allow the movable end 200 to open smoothly; when the connecting rod 300 rotates clockwise to the maximum angle, the opening and closing angle reached by the movable end 200 is at the maximum position, and at the same time, the sliding plate 600 slides to the side close to the damping lever 800. In order to prevent the sliding plate 600 from exceeding the stroke, the present embodiment also provides a limiting mechanism, which includes a limiting lever 1200 rotatably arranged on the outside of the damping lever 800, the lower end of the limiting lever 1200 is against the rear end of the sliding plate 600, and the upper end of the limiting lever 1200 is provided with a limiting portion 1210. When the sliding plate 600 moves toward the damping lever 800, the limiting portion 1210 is against the rear end of the sliding plate 600, thereby ensuring the stability of the movable end 200 when it is opened to the maximum angle.

[0025] As mentioned above, the connecting rod 300 of the connecting rod 300 mechanism needs to push the sliding plate 600 to slide horizontally through the abutting portion 310 when the movable end 200 is opened by rotating clockwise. In this embodiment, an abutting roller 1100 that rolls with the edge of the sliding plate 600 is provided at the end of the abutting portion 310. The abutting roller 1100 rolls with the edge of the sliding plate 600 to reduce friction and improve the smoothness of the hinge when opening and closing. In addition, when the movable end 200 is opened to the maximum angle, in order to ensure the stability of the contact position between the abutting portion 310 and the sliding plate 600, a positioning groove is provided at the front end of the sliding plate 600 in this embodiment. After the connecting rod 300 rotates clockwise, the abutting roller 1100 can be inserted into the positioning groove. After the abutting roller 1100 is inserted into the positioning groove, the stability is improved.

[0026] As mentioned above, the hydraulic cylinder 700 on the sliding plate 600 is used to play a supporting role, so that the tension generated by the sliding plate 600 when sliding is balanced with the elastic force of the damping spring 1000. In this embodiment, a mounting groove for accommodating the hydraulic cylinder 700 is provided on the sliding plate 600, and the piston end of the hydraulic cylinder 700 is connected to the connecting part provided in the fixed end 100, so as to achieve stable installation.

[0027] like Figure 1 and Figure 2 As shown, in order to improve the application scope of the device, in this embodiment, a plurality of mounting columns 910 arranged in parallel up and down are provided at one end of the damping slider 900 away from the damping lever 800, and the end of the damping spring 1000 is sleeved on the mounting column. At the same time, an adjustment block is provided at the end of the fixed end 100 opposite to the damping slider 900, and the adjustment block is provided with an adjustment screw 920 for adjusting the compression amount of the damping spring 1000. When in use, different numbers of damping springs 1000 can be selected and installed according to the weight of the cabinet door installed at the movable end 200, and the spring damping can also be adjusted according to the use situation, so as to be suitable for installation in different scenes. When the weight of the cabinet door is large, multiple damping springs 1000 can be selected for installation. In this embodiment, a receiving groove for accommodating the damping spring 1000 is provided between the damping slider 900 and the adjustment block in the fixed end 100. The provision of the receiving groove is conducive to improving the stability of the structural installation of the damping spring 1000. Since the movable end 200 needs to be installed with structures such as cabinet doors, the present embodiment provides a detachable mounting block 210 on the movable end 200, and the mounting block 210 is provided with mounting holes, so that the movable end 200 and the cabinet door structure can be fixed by screw installation during installation, which is convenient for installation and disassembly.
