Detailed Description

As shown in fig. 1 to 8, a torsion-adjustable self-rebounding hinge includes a first hinge plate 1 and a second hinge plate 2, which are hinged to each other, the first hinge plate 1 and the second hinge plate 2 have coaxial shaft sleeves, and a shaft core assembly is inserted into the shaft sleeves, the shaft core assembly includes an adjusting device 3 and a fixing device 4, which are located at two ends, the adjusting device 3 includes an adjusting base 31 and an adjusting device 32, which is located inside the adjusting base and can rotate and axially slide relative to the adjusting base, the inward end of the adjusting base 31 is provided with a plurality of protrusions 311, which are circumferentially spaced apart from each other, the outward end of the adjusting device 32 is provided with a plurality of grooves 321, which are circumferentially spaced apart from each other and are matched with the protrusions, the protrusions 311 and the grooves 321 are the same in number and are correspondingly clamped together one to one, a spring is connected between the adjusting device 32 and the fixing device 4, and two ends of the spring are fixedly connected or clamped with the adjusting device and the fixing device, the relative rotation between the two ends of the spring and the regulator and the fixer is avoided, the regulator drives the corresponding end of the spring to be synchronously twisted when rotating, the middle of the outward end of the regulator 32 is provided with a regulating hole 322 matched with a spanner, the regulating hole is a hexagon socket, and the spring generates thrust outward (namely, toward the direction of the regulating base) to the regulator so as to keep the lug of the regulating base and the groove of the regulator in a joint state; the middle of the adjusting base 31 is provided with a through hole for exposing the adjusting hole. The user uses corresponding spanner to insert in the adjusting hole on the regulator, presses the regulator inwards (to the fixer direction), when pressing to the recess that the lug of adjusting the base breaks away from the regulator with the spanner toward needs increase or reduce the direction rotation of spring torsion can, adjust the back that targets in place, loosen the spanner regulator and outwards reset under the thrust effect of spring, make the recess on the regulator and the lug of adjusting the base rejoin. The utility model discloses torsion adjustable is from resilience hinge reasonable in design, convenient to use, the practicality is strong, can change the best closed effect that torsion size obtained the door very conveniently to satisfy the operation requirement of the different door of weight, avoid because of spring torsion appears strong impact sound or causes the door to damage easily when leading to closing the door too greatly, also avoid torsion too little the unable closed phenomenon of door plant to appear.

2. The phenomenon that the door plate cannot be closed occurs when the torsion is too small.

The spring plays the effect of propping up the return to the regulator when playing the hinge from the rebound effect to guarantee that the lug of adjusting the base keeps mutually engaging with the recess of regulator under initial condition all the time.

In this embodiment, to prevent the user from adjusting the spring to a force value angle that exceeds the spring load when adjusting the torsion, the outward end of the adjuster 32 is provided with a shaft part extending into the through hole of the adjusting base, the adjusting hole 322 is positioned on the end surface of the shaft part of the adjuster, the inner wall of the through hole of the adjusting base 31 is provided with a first limit block 312 for limiting the rotating angle of the adjuster, the side surface of the shaft part of the adjuster 32 is provided with a second limit block 324 which is matched with the first limit block 312 to limit the maximum rotation angle of the adjuster, when a user twists the adjuster until the first limit block of the adjusting base and the second limit block of the adjuster are mutually abutted, the spring cannot be adjusted to a larger torsion force value, therefore, the spring is prevented from working under the condition of exceeding the load, and the failure of the spring due to overlarge torsion angle is avoided.

In this embodiment, a pair of first bushings 11 is disposed at two ends of a side edge of the first hinge plate 1, and a second bushing 21 located between the two first bushings is disposed at a side edge of the second hinge plate 2; the adjusting base is fixed in a first shaft sleeve at one end of the first hinge plate through a screw 6, and the fixer is fixed in a second shaft sleeve through a screw 6 and extends into the first shaft sleeve at the other end of the first hinge plate; a limit screw 7 penetrates through the side part of the first shaft sleeve 11 at the other end of the first hinge plate 1, and an arc-shaped limit groove 41 matched with the limit screw 7 is formed in the side part of the fixer 4; when the hinge is opened to a certain angle, the limit screw and the limit groove mutually support to ensure that the hinge cannot be opened to a larger angle, thereby limiting the door opening angle.

In this embodiment, the inward end of the adjuster 32 is provided with a first clamping groove 323 matched with one end of the spring in a clamping manner, the inward end of the fixer 4 is provided with a second clamping groove 42 matched with the other end of the spring in a clamping manner, and the two ends of the spring are clamped into the first clamping groove and the second clamping groove, so that relative rotation between the two ends of the spring and the adjuster and the fixer is avoided.
