Description

Bidirectional reset hinge

Technical Field

The utility model relates to a hinge is a two-way hinge that resets.

Background

A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow rotation between them; which are typically constructed of movable components, or foldable materials. Some hinges used in the industry at present are one-way reset hinges, corresponding limiting features need to be made on a door frame, and the door frame can only be opened towards a single side. Other hinges are bidirectional reset hinges, such as the grant publication number CN215108234U, the grant publication date 2021.12.10, and the utility model named "bidirectional spring hinge structure" disclosed in the chinese patent literature; the hinge comprises a lower hinge and an upper hinge hinged on one side of the lower hinge, wherein one side of the lower hinge is hinged with an elastic part which elastically pushes against the upper hinge, and the elastic part can enable the upper hinge to rotate towards a first direction or a second direction opposite to the first direction relative to the lower hinge; the hinge is hinged on the lower hinge through the elastic piece with one end abutting against the upper hinge, so that the upper hinge can rotate towards a first direction or a second direction opposite to the first direction relative to the lower hinge, and the requirement of bidirectional rotation is met. But the production cost of the product is higher, and the production and assembly are inconvenient.

Disclosure of Invention

In order to overcome the defects, the utility model aims to provide a bidirectional reset hinge to the field, which is inconvenient for the production and assembly of the prior similar products, high in production cost, poor in stability of both sides and positive and negative rotation and poor in reset effect. The purpose is realized by the following technical scheme.

A two-way reset hinge is characterized in that a fixed hinge and a movable hinge of the hinge are respectively provided with a mounting hole, a fixed shaft hole at one side of the fixed hinge is hinged and fixed with a movable shaft hole at one side of the movable hinge through a pin, and the outer diameter of the pin at the hinged position is provided with a torsion spring; the utility model has the advantages of its structural design main points are the torsional spring includes first torsional spring and second torsional spring, the tip of first torsional spring and second torsional spring is the moment of torsion respectively, the compression volume is the same, and the torsional spring of anticlockwise or clockwise forward and reverse compression, be equipped with middle dead axle hole between the dead axle hole of both sides in the dead hinge, first torsional spring and second torsional spring symmetry set up in the middle dead axle hole both sides pin external diameter of dead hinge, the tip of first torsional spring and second torsional spring is fixed in the dead groove of dead hinge both sides respectively, and move the middle recess that moves of hinge, the first torsional spring and the second torsional spring of pin are adorned the dead hinge and are moved the hinge through symmetry direction of rotation and push type respectively. Therefore, the hinge is opened and reset in two directions, and the double torsion springs are assembled in the symmetrical rotating direction to provide the same torque for positive and negative rotation; simultaneously, two torsional spring push type installations reduce the equipment degree of difficulty of this hinge, can not cause the influence to customer's installation simultaneously.

The fixed shaft hole of the fixed hinge and the movable shaft hole of the movable hinge are respectively a circle rolling hole formed by bending a plate, and the fixed groove of the fixed hinge and the movable groove of the movable hinge are respectively edge grooves formed by punching. The rolling round holes of the fixed hinge and the movable hinge are matched with the pins in a hinged mode, so that the production cost is further reduced, and the production and assembly are facilitated.

The pin is a pin, one end of the pin extends out of the fixed shaft hole of the fixed hinge, and the end part of the pin is provided with a retaining ring for a shaft. Thereby facilitating further fixation and assembly between the fixed hinge and the movable hinge.

The utility model has simple and reasonable structure design, convenient production, assembly, use and installation, low production cost, and especially good stability of forward and reverse rotation; the hinge is suitable for being used as a cabinet door of an electric cabinet, a hinge of a box body or a cabinet in the industries of telecommunication, electric power, automatic control manufacturing, engineering machinery and the like, and the structural improvement of similar products.

Figure number and name: 1. the shaft retainer comprises a fixed hinge, 101, a fixed groove, 102, a middle fixed shaft hole, 2, a movable hinge, 201, a movable groove, 3, a first torsion spring, 4, a pin, 5, a second torsion spring, 6 and a shaft retainer ring.

Detailed Description

The structure and use of the present invention will now be further described with reference to the accompanying drawings. As shown in figures 1-3, a fixed hinge 1 and a movable hinge 2 of the hinge are respectively provided with a mounting hole, a fixed shaft hole at one side of the fixed hinge and a movable shaft hole at one side of the movable hinge are hinged and fixed through a pin 4, and the outer diameter of the pin at the hinged position is provided with a torsion spring. The torsion springs comprise a first torsion spring 3 and a second torsion spring 5, the end parts of the first torsion spring and the second torsion spring are respectively torque and have the same compression amount, and are torsion springs compressed in the clockwise direction or the clockwise direction, middle fixed shaft holes 102 are arranged between the fixed shaft holes in the two sides of the fixed hinge, the first torsion spring and the second torsion spring are symmetrically arranged on the outer diameters of pins in the middle fixed shaft holes in the fixed hinge, the end parts of the first torsion spring and the second torsion spring are respectively fixed in fixed grooves in the two sides of the fixed hinge, and a movable groove in the middle of the movable hinge, and the first torsion spring and the second torsion spring of the pins are respectively installed in the fixed hinge and the movable hinge through the symmetrical rotating direction and the pressing type. The fixed shaft hole of the fixed hinge and the movable shaft hole of the movable hinge are respectively a rolling hole formed by bending a plate, and the fixed groove 101 of the fixed hinge and the movable groove 201 of the movable hinge are respectively edge grooves formed by punching. The pin is a pin, one end of the pin extends out of the fixed shaft hole of the fixed hinge 1, and the end part of the pin is provided with a retaining ring 6 for the shaft.

When the hinge is installed through the fixed hinge and the movable hinge, the first torsion spring and the second torsion spring which are opposite in rotation direction and have customized angles are fixed on the fixed hinge and the movable hinge. In the initial state of the hinge after installation, the two torsion springs have specific compression amount, and one positive torsion spring and the other negative torsion spring are mutually offset to keep the initial state of the hinge. When the door plate is opened towards one side, one of the two torsion springs is compressed in the positive direction, and the other torsion spring is compressed in the reverse direction to provide a reset torque. The reverse opening is also realized by one type of forward compression of the two torsion springs and the reverse compression of the other type of the two torsion springs, so that the reset torque is provided, and the hinge reset is realized.
