Abstract

The utility model discloses a universal hinging device, which comprises a ball socket body (1) and a ball head body (2), wherein the ball socket body (1) comprises two ball socket cover plates (3, 4) which are approximately in the same structures; the two ball socket cover plates are connected through an anti-drop bolt (5) to form a ball socket cavity (6); the ball head body (2) comprises a ball head (7) and a ball head hanging plate (8); through holes (9) are arranged in the ball head hanging plate (8); the ball head (7) is embedded into the ball socket cavity (6); and a structure (10) used for being connected with other objects is arranged at the bottom of the ball socket cover plate (4). The universal hinging device is reasonable and simple in structure, products connected with the universal hinging device can mutually and freely rotate in each direction, so that the degree of freedom is higher.

Description

The universal hinging device

Technical field

The utility model relates to a kind of connection set, relates in particular to a kind of universal hinging device that can make two connection object rotations free of one another on all directions.

Background technique

In production practices, for two members are realized being flexibly connected, can apply to a large amount of connection sets.The degrees of freedom that at present mostly is connection set is less, and along with the development of economic society, the variation of product function is also had higher requirement to articulating device.Only possess rotary freedom such as traditional articulated manner, not too be applicable to some stressed relative complex and the degrees of freedom number is required higher occasion.Although some universal connectors occurred at present, such device is the structure relative complex mostly, and is expensive.

Summary of the invention

The purpose of this utility model is the shortcoming that overcomes prior art, provide a kind of simple in structure, can make the universal hinging device that realization is freely rotated on the two construction all directions.

For solving the problems of the technologies described above, concrete technological scheme of the present utility model is as follows:

A kind of universal hinging device comprises ball-and-socket body and bulb body, and described ball-and-socket body comprises two ball-and-socket cover plates, and two ball-and-socket cover plates consist of a ball-and-socket cavity after connecting by the bolt that falls;

Described bulb body comprises bulb and ball-clevis, has the hole of perforation at described ball-clevis; Described bulb embeds in the described ball-and-socket cavity;

In a described ball-and-socket cover plate bottom structure that connects other objects is set also.

The bolt number of described connection two ball-and-socket cover plates is 3 further, is triangle at the ball-and-socket cover plate and arranges.

Further, described linkage structure integral body is U-shaped body, has the hole that runs through two walls at U-shaped body.

Further, one deck elastic ball pad is set in the ball-and-socket cavity bottom of described ball-and-socket body.

The utility model is simple and reasonable, realizes mutually rotating on the two construction all directions, has stronger practicability.

Embodiment

Come the utility model is done to describe further below in conjunction with accompanying drawing.

Shown in Fig. 1,2,3 and 4, the utility model universal hinging device comprises ball-and-socket body 1 and bulb body 2, described ball-and-socket body 1 is comprised of two roughly the same ball-and-socket cover plates 3 and 4 of structure, is by three between the two ball-and-socket cover plates can consist of ball-and-socket cavity 6 after bolt 5 that triangle arranges connects; Described bulb body 2 comprises bulb 7 and ball-clevis 8, bulb 7 embeds in the described ball-and-socket cavity 6 can realize ball-and-socket body 1 and bulb body 2 freely rotating on all directions, and mutually do not break away between the two, the hole 9 that the ball-clevis 8 on described bulb body 2 has a perforation is realized and being connected of other objects.Ball-and-socket cover plate 4 bottoms at ball-and-socket body 2 arrange the structure 10 that is connected with other objects, described linkage structure 10 global shapes are U-shaped body, have the hole 11 of two walls that run through at U-shaped body, so just can be connected with other objects by the mode that bolt or pin connect, two after independently parts connect through the utility model universal hinging device, two articles can be realized mutually freely rotating in all directions, and higher degrees of freedom is arranged.Simultaneously in described ball-and-socket cavity 6 bottoms, one deck elastic ball pad 12 is set, so just so that have elasticity between bulb body 2 and the ball-and-socket body 1, has avoided again having simultaneously direct rigidity contact between the two, make product have the life-span of growing.

The utility model universal hinging apparatus structure advantages of simple after the two articles connection two articles freely being rotated mutually, has stronger practicability on all directions.

Claims

1. universal hinging device, comprise ball-and-socket body (1) and bulb body (2), it is characterized in that: described ball-and-socket body (1) comprises the roughly the same ball-and-socket cover plate of two structures (3,4), and two ball-and-socket cover plates (3,4) consist of a ball-and-socket cavity (6) after connecting by the bolt that falls (5); Described bulb body (2) comprises bulb (7) and ball-clevis (8), has the hole (9) of perforation at described ball-clevis (8); Described bulb (7) embeds in the described ball-and-socket cavity (6); In a described ball-and-socket cover plate (4) bottom the structure (10) that connects other objects is set also.

2. universal hinging device according to claim 1, it is characterized in that: the bolt number of described connection two ball-and-socket cover plates (3,4) is 3, is triangle at the ball-and-socket cover plate and arranges.
