Description

Movable hinge and cabinet door connection structure with same
Technical Field
The invention belongs to the technical field of household, and relates to a movable hinge and a cabinet door connecting structure with the movable hinge.
Background
The side-hung door of the cabinet furniture is usually formed by connecting one side of a cabinet door with a cabinet body through a fixed hinge such as a hinge, wherein the fixed hinge refers to a cabinet door with a specific hinged side and a movable side, the cabinet door can be opened only from the direction of the movable side, the space required for allowing the cabinet door to swing around the hinged side is reserved at the corresponding position of the movable side for normal use, in the actual application scene, the situation of re-placing objects often exists, if a certain object is required to be placed in the space required for opening the cabinet door, the problem is caused that the subsequent arrangement of a household is inconvenient; moreover, the existing furniture is generally formed between boards in a factory customization mode, then hardware is installed on site, boards are damaged to different degrees in the installation process of the hardware, performance of the boards such as water resistance and moisture resistance is reduced, the installation of hinges is taken as an example, the door opening side needs to be selected according to the actual condition of the site, grooving, perforating and other works needed for installing the hinges are completed on site, and compared with the factory, the technology of site construction is difficult, the technology affects attractiveness of a cabinet body (nail holes and the like), firmness of the hardware (such as poor accuracy of perforating on-site construction) and poor moisture resistance and water resistance (dimensional deviation of perforating grooves is exposed).
In addition, because of reasons such as using habit, only can the unilateral open cabinet door can cause inconvenience to the use, if the direction of opening the door can be selected wantonly, this kind of cabinet door can be higher-end, use more handily, the operation is lighter.
Disclosure of Invention
A first object of the present invention is to provide a living hinge, which solves the above-mentioned problems of the prior art, and the present invention provides a living hinge, so that a hinge side and a living side can be switched.
The aim of the invention can be achieved by the following technical scheme: the movable hinge is characterized by comprising a door body mounting part and a door frame mounting part matched with the door body mounting part, wherein the door body mounting part comprises a strip-shaped first sliding rail and two sunk cover plates with insertion holes, the door frame mounting part comprises a second sliding rail, a toothed belt and two traction wheels, a sliding block is fixedly arranged on the toothed belt, a pin shaft is arranged on the sliding block, one end of the pin shaft is provided with a first roller eccentrically arranged with the pin shaft, the first roller is matched with the first sliding rail, the other end of the pin shaft is rotationally connected with a second roller matched with the second sliding rail, the two traction wheels pull the toothed belt to form flat sections of two toothed belts, one toothed belt of the flat sections is fixedly connected with the sliding block, and a guide groove allowing the toothed belt of the other flat section to slide is formed on the sliding block;
the middle part of traction wheel wears to be equipped with a connecting nail, be connected with a strip between connecting nail and the traction wheel, threaded connection has the plug tongue with the jack adaptation on the connecting nail.
Further, a buffer spring is connected between the traction wheel and the insert tongue.
Furthermore, the traction wheel is provided with a first guide conical surface, the insert tongue is provided with a second guide conical surface symmetrical to the first guide conical surface, a locking ring groove is formed between the first guide conical surface and the second guide conical surface, and the sliding block is provided with a positioning jaw matched with the locking ring groove.
