Abstract

A pin-free hinge, comprising a door frame leaf (A) and a door leaf (B). Multiple hollow hinge cylinders (1, 2) are formed at side surfaces of the door leaf (B) and the door frame leaf (A), and the hollow hinge cylinder (2) of the door leaf (B) is set between the hollow hinge cylinders (1) of the door frame leaf (A). Among the hollow hinge cylinder (2) of the door leaf (B) and the hollow hinge cylinders (1) of the door frame leaf (A), one pair of adjacent hollow hinge cylinders (1, 2) is provided with a planar ball bearing (5) therebetween. The planar ball bearing (5) comprises a pair of races (51) and multiple spherical balls (52). Annular recesses (a) having a semi-circular cross section are provided in the races (51). The two races (51) are joined oppositely, and the two annular recesses (a) form a channel having a circular cross section. The multiple spherical balls (52) are disposed in the channel, and match a wall of the channel. The races (51) rotate on the spherical balls (52), and are limited by the spherical balls (52). The hinge of the present invention has superior stability, endurance, and load-carrying capacity, and improves smoothness during use to enable an easy open or close operation.

Description

A hingeless hinge

Technical field

The invention belongs to a hinge of a door and window, and relates to an improvement of a hinge structure, and more particularly to a hinge without a shaft core bearing.

Background technique

The traditional hinge includes a door leaf page and a door frame page, and a plurality of hinge tubes are formed at the side of the door leaf page and the door frame page, and the door leaf page and the door frame page are inlaid with each other through the hinge tube, and the inner hole is penetrated from top to bottom by a shaft core The function of the connection and the tube is positive. When the hinge is mounted on the door frame, the weight of the door leaf directly acts on the entire connecting shaft core through the hinge tube of the door leaf page, so that the entire connecting shaft core is tightened. When the door leaf is opened and closed, the whole shaft core is directly rubbed with all the hinge tubes, which easily causes the shaft core and the inner wall of the hinge tube to wear, causing the hinge to be deformed or even damaged. In addition, due to the hinge Relying on the direct sliding friction between the hinge tube and the shaft core to realize the rotation of the door leaf, there is a disadvantage that the resistance of the door leaf opening and closing is large, and the operation is laborious, and the door leaf hinge tube carries the weight of the door leaf, and The sliding of the door frame hinge pipe directly causes friction and damage of the hinge pipe.

Summary of the invention

It is an object of the present invention to provide a hinge having a new structure in which the hinge tube of the door frame and the hinge tube of the door leaf are no longer connected by the shaft core, but instead are connected by bearings, not only It has better stability, durability and load-bearing performance, and it is smoother to use, and it is easier to open and close.

The object of the invention is achieved in this way:

A hingeless hinge, including a door frame page and a door leaf page, a side of the door leaf page and the door frame page A plurality of hinge tubes are formed at the same time, and the hinge tubes of the door leaf sheets are embedded between the hinge tubes of the door frame sheets; and the hooks of the door leaf sheets and the hinge tubes of the door frame sheets have a pair of adjacent hinge tubes A planar ball bearing is arranged between the two; the planar ball bearing comprises a pair of bead disks and a plurality of circular balls, wherein the bead disk has an annular groove with a semicircular cross section, the two bead disks face each other, and the two annular grooves The channel is formed in a circular cross section, and a plurality of circular balls are placed in the channel, and some of the circular balls are matched with the wall of the channel, and the bead disk rotates on a plurality of round balls and is limited by a plurality of round balls.

In the solution, the hinge tube of the door leaf page and the hinge tube of the door frame page, wherein the planar ball bearing is installed between a pair of adjacent hinge tubes, and the connection pins or connections can be installed between other adjacent hinge tubes. Pin and needle bearings or connecting pins and ball beads or the like for active connection.

Thus, when the door leaf page is rotated relative to the door frame page, the bead plate mounted on the door leaf hinge tube can roll on a plurality of round balls, and at the same time, the bead disk is restricted by a plurality of round balls, and cannot be moved in any of the front, rear, left and right directions. , can play a positive role at the same time.

The hinge obtained thereby can be connected by a flat ball bearing, a front door frame and a door leaf, and the weight of the door leaf is carried by the planar ball bearing, so that the core of the conventional hinge can be eliminated, and a shaftless core is obtained. The hinge structure.

The invention creates a hinge without a shaft core, adopts rolling instead of the traditional sliding, and cancels the shaft core, not only has small rolling friction force, but also no sliding friction between the shaft core and the hinge tube, and the resistance during use thereof It is also smaller, which makes it more smooth and labor-saving to use, and also helps to extend the life of the product.

In the hingeless hinge of the invention, since the shaft core is eliminated, the upper and lower hinge tubes no longer interact with each other through the shaft core, and in particular, the hinge tube of the door leaf sheet can be overcome due to the gravity of the door leaf, and the tilting and the acting shaft are easily generated. The core and the shaft core affect the cooperation of the shaft core with other hinge tubes.

The hingeless hinge of the invention adopts the flat ball bearing design, not only the weight of the bearing door leaf is greatly improved, but also the structure of several round balls and the channel can play a positive or no deviation during the rotation of the bead disk. The role of the hinge to ensure the stability of the hinge during the rotation.
