A lifting hinge structure

Abstract

The invention discloses a lifting hinge structure. The lifting hinge structure comprises an upper sleeve, a lower sleeve, a connecting rod, a first hinge piece and a second hinge piece. A sealed sleeve bottom is arranged on the upper sleeve. An inner gear is arranged on the inner cylinder wall of the upper sleeve. A stepped hole is formed in the lower sleeve cylinder. A big hole and a small hole in the stepped hole are eccentrically arranged. The connecting rod comprises an abutting portion, a gear portion and a guide column which are fixedly connected into a whole from top to bottom. The guide column of the connecting rod is spirally connected into the small hole of the stepped hole in the lower sleeve and drives the first hinge piece to drive the upper sleeve on the first hinge piece to rotate. Due to the fact that the inner gear on the inner cylinder wall of the upper sleeve and the gear portion on the connecting rod are eccentrically arranged and internally engaged with each other, the gear portion on the connecting rod rotates to drive the connecting rod to spirally rotate up and down in the small hole of the lower sleeve, the abutting portion on the connecting rod abuts against the sleeve bottom of the upper sleeve, and the upper sleeve and the first hinge piece fixedly connected with the upper sleeve ascend and descend in the axial direction. By the adoption of the lifting hinge structure, the large-range angle rotation can be achieved, the structure is simple, and disassembly, assembly and operation are facilitated.

Description

technical field [0001] The invention relates to the technical field of hinge structures, in particular to a rotatable lifting hinge structure. Background technique [0002] At present, in the field of housing construction, the hinge structure used in the shower room door is generally a common flat hinge, that is, it rotates in the same horizontal direction to realize the opening and closing of the shower room door. The gap between the door and the floor flows out. The common form of waterproofing is to install waterproof rubber strips under the shower door. Because of this, if the shower door is turned in the same horizontal direction, the shower door is in the process of turning. In the process, the waterproof rubber strip is always close to the ground and rotates, which will not only create resistance to the push-pull process of the shower room door, but also easily wear out the waterproof rubber strip installed under the shower room door, resulting in waterproof failure a...

[0002] At present, in the field of housing construction, the hinge structure used in the shower room door is generally a common flat hinge, that is, it rotates in the same horizontal direction to realize the opening and closing of the shower room door. The gap between the door and the floor flows out. The common form of waterproofing is to install waterproof rubber strips under the shower door. Because of this, if the shower door is turned in the same horizontal direction, the shower door is in the process of turning. In the process, the waterproof rubber strip is always close to the ground and rotates, which will not only create resistance to the push-pull process of the shower room door, but also easily wear out the waterproof rubber strip installed under the shower room door, resulting in waterproof failure and scratches on the ground; in addition , the existing shower room door also has a structural form that uses a rotating lifting hinge, but the structure of the lifting hinge used to realize the lifting is relatively complicated, and usually due to the influence of the lifting structure, the rotation angle of the lifting hinge is limited. The rotation of a wide range of angles cannot be realized, resulting in the limitation of the lifting hinge due to the different angles between the two shower room doors, and there are also problems such as complicated disassembly and assembly of the hinge
