Problems solved by technology

[0009] The technical problem to be solved by the present invention is to overcome the disadvantages of hinges in the prior art or cumbersome installation that takes up a lot of space, or the impact force caused by the accumulation of kinetic energy, or cannot be self-closing and is not humanized enough to provide a hinge with adjustable restoring force and speed. Hinges of the same size, self-closing, and small outer diameter

Embodiment 1

[0044] Embodiment 1: as Figure 1~3 As shown, a multifunctional adjustable self-closing buffer hinge includes a main shaft 1, a leaf 2 and a leaf 2 3 provided with a rotating tube, a lower end cover 21 and an upper end cover 31, and the main shaft 1 is provided with an elastic transmission Device 4, clutch 5 and damper 6, wherein:

[0045] Elastic transmission device 4 comprises the helical spring 41 that one end is fixedly connected with the lower end of main shaft 1 and the other end is connected with the turntable 42 that is located at the inner upper end of sheet-2 rotating tube, and turntable 42 is sliding fit with main shaft 1, and the lower end of main shaft 1 It is an oblate structure, and the oblate structure utilizes the oblate hole located at the center of the lower end cover 21 to be fixedly connected to the lower end of the sheet-2 rotating tube; the oblate structure is provided with a right-angled notch 11 to connect with the coil spring 41 lower ends are connec...

Embodiment 2

[0056] Embodiment 2: The helical groove on the main shaft 1 has a turning arc section 121 at a position of 5° to 10° from the lower end of the spiral groove, and the lift of the turning arc section is smaller than the lift of the rest of the helical groove; Due to the small lift of the turning arc section, the relative movement of the sliding kingpin in the turning arc section is accelerated when the door is closed. This acceleration causes the door to obtain a local impact force to achieve the effect of automatic locking of the door lock, such as Figure 11 shown.

Abstract

The invention discloses a multifunctional adjustable self-closing buffer hinge which comprises a main shaft, a flange I, a flange II, a lower end cover and an upper end cover, wherein the main shaft is provided with an elastic transmission device, a clutch and a damper; the elastic transmission device comprises a spiral spring connecting the main shaft and a turntable; the clutch comprises a turntable and a fixing sleeve in sliding fit with the main shaft; the lower end of the fixing sleeve in fixed fit with the flange II is in sliding fit with the outside of the upper end of the turntable; the turntable, the fixing sleeve and the main shaft are provided with rolling grooves and separated / combined by rotation pins; the damper consists of the main shaft, the fixing sleeve, a piston, a sliding main pin, the flange II, a flow rod and the upper end cover; the main shaft is provided with a spiral groove; the fixing sleeve is provided with a sliding groove; the lower end of the piston is in sliding fit with a center hole of the main shaft; the sliding main pin is fixed at the lower end of the piston and is in sliding fit with the spiral groove and the sliding groove; an oil storage cavity is arranged in a rotation pipe of the flange II; the flow rod fits with a center regulation hole of the piston; and a one-way valve is arranged at the upper end of the piston. In the invention, the closing damping has a self-closing function as the piston is arranged axially, an arbitrary stop section is set, and the damping is adjustable.

Description

technical field [0001] The invention belongs to the technical field of hinges, and in particular relates to a self-closing adjustable buffer hinge. Background technique [0002] A general hinge is composed of a main shaft and two leaves, one leaf is installed on the door, and the other leaf is installed on the door frame, and the door can be opened or closed by rotating the leaf around the main shaft, but the existing hinge is In the process of use, there are many deficiencies. Although there are various improvements for hinges, there are still unsatisfactory aspects. For example, [0003] 1. Spring hinges using only torsion springs, such as the hinge described in Chinese Patent No. ZL200510129600, named "damper", the hinge will continue to accelerate the closing speed of the door due to the continuous action of the spring tension, often causing personnel Accidental injury and damage to the door frame from repeated impacts; [0004] 2. No spring hinge, such as the hinge de...
