Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

The first embodiment is as follows:

as shown in fig. 1 and 2, the positioning mechanism comprises a positioning cover 1 mounted on a hydraulic hinge, and a thread or buckle structure is formed below the positioning cover 1 and is used for being connected and fixed with a hydraulic hinge shell 6. The positioning cover 1 is provided with 3 through holes 13, internal threads 15 for fixing screws are arranged in the through holes 13, and the through holes 13 are separated by 120 degrees, so that the through holes 13 can be found to install or disassemble the screws when the door rotates to any angle.

The positioning cover 1 is provided with a cavity 11, the cavity 11 penetrates through the positioning cover 1, an inner cover 2 is installed in the cavity 11, the positioning cover 1 is connected with the inner cover 2 through a detachable limiting part 3, and the limiting part 3 is preferably a screw. As shown in fig. 3, the inner cap 2 is provided with annular knurls 23 for increasing the friction force with the screw. As shown in fig. 7, a gap 4 exists between the inner cover 2 and the positioning cover 1, when the through hole 11 is not screwed with a screw, the inner cover 2 and the positioning cover 1 are relatively independent due to the gap 4, that is, the positioning cover 1 does not drive the inner cover 2 to rotate, and does not touch the inner cover 2 to generate friction force to hinder the rotation of the positioning cover 1.

As shown in fig. 4 and 1, a long hole 21 and an inner cavity 22 matched with the inner hexagonal wrench in shape are formed in the inner cover 2, the long hole 21 is communicated with the inner cavity 22, so that the inner hexagonal wrench can penetrate into the inner cover and rotate the shaft core 5 by means of friction force between the inner hexagonal wrench and the inner cover, and thus the automatic reset angle of the hydraulic hinge is adjusted. The opening shape of the other end of the long hole 21 is matched with a fixing block 51 formed on the shaft core 5, and the fixing block 51 is clamped in the long hole 21 to realize the fixed connection between the shaft core 5 and the inner cover 2.

The specific working process of the scheme is as follows:

inner cup 2 is fixed on axle center 5, and location lid 1 screw thread is screwed up on hydraulic hinge, has replaced the position of original hydraulic hinge end cover.

If need hydraulic pressure hinge automatic re-setting's function, only need to pass through-hole 13 wrong through one or more pieces of screw, screw one end can be supported annular knurl 23, the tighter the screw is twisted, the screw is more inseparable to the one end of annular knurl 23, when the door is opened, the blade of shaping on hydraulic pressure hinge casing 6 rotates along with the door, location lid 1 rotates along with it, under the effect of screw, inner cup 2 drives axle core 5 and rotates together, because the rotation of axle core 5 has made hydraulic pressure hinge produce the restoring force, hydraulic pressure hinge this moment has automatic re-setting's function.

If the function of automatic resetting of the hydraulic hinge is to be cancelled, a tool is used for screwing out the screw, so that the positioning cover 1 and the inner cover 2 are relatively independent. Because the inner cover 2 is installed on the shaft core 5 and has a gap 4 from the inside of the positioning cover 1, the positioning cover 1 does not drive the inner cover 2 to rotate when rotating. Therefore, when the door is opened, the positioning cover 1 rotates under the action of the blades, the inner cover 2 and the shaft core 5 are kept in the original state, and the hydraulic hinge does not have the function of automatic resetting.

If people want to adjust the automatic resetting angle of the hydraulic hinge, the screw in the through hole 13 is taken out, then an inner hexagonal wrench is used, the inner hexagonal wrench is inserted from the inner cavity 22 formed by the strip hole 21, and therefore the inner cover 2 and the shaft core 5 are screwed to adjust the automatic resetting angle of the hydraulic hinge.

The utility model discloses simple structure only needs to replace the end cover of the popular hydraulic pressure hinge on the market, can realize freely switching of automatic re-setting function, and need not to change whole hydraulic pressure into the hydraulic pressure hinge that can automatic positioning, and is very economical convenient.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
