Abstract

The utility model discloses an articulation positioning device for furniture. The articulation positioning device for the furniture comprises a fixing seat, a boss clamping seat, a articulation seat, a positioning wrench and a rivet. The articulation positioning device of the furniture is characterized in that the articulation seat is articulated with the fixing seat through the rivet; a limiting wall limits the rotation of the articulation seat towards one direction; the boss clamping seat is arranged at one side of the articulation seat; the boss clamping seat rotates along with the positioning wrench to a position in back of a boss cambered surface and a arc wall; and the rotation of the articulation seat towards another direction is limited, so that the articulation seat achieves a locked positioning state; and the articulation seat can rotate towards one direction around the fixing seat after the positioning wrench is rotated to separate the boss cambered surface and the arc wall, so as to achieve a free rotation state. Therefore, the articulation positioning device is simple in structure, convenient to operate and suitable for being used as accessories of the furniture and the like.

Description

The hinged detent of furniture

Technical field

The utility model relates to the hinged detent of a kind of accessory of furniture, particularly a kind of furniture.

Background technique

In the furniture that uses at present, have in the fold mechanism of hinging par, hinging par adopts supporting hinges to support usually, and supporting hinges is made of two metals, and there is shearing point in this supporting hinges, and in use, there is potential safety hazard in easy tong; Also have part furniture to adopt support tube to be located by connecting, this structure in use needs separately support tube to be dismantled and fixedly mounted, and cause operating process more loaded down with trivial details, and consumptive material is many.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of hinged detent of furniture, can simplify structure, and is easy to operate and eliminate safe hidden trouble.

The technological scheme that the utility model adopts is: a kind of hinged detent of furniture, and it comprises fixed base, boss deck, hinged seat, dowelled spanner, rivet; It is characterized in that the boss deck is hinged by dowelled spanner and fixed base; Hinged seat is hinged by rivet and fixed base.

Described fixed base is provided with macropore, hinging hole, aperture, limited wall, and macropore is coaxial setting with aperture, and hinging hole is arranged on a side in macropore and axle center, aperture place, and limited wall is arranged on a side of hinging hole.

Described boss deck is provided with profiled holes and boss cambered surface, profiled holes and macropore and the coaxial setting of aperture.

Described hinged seat is provided with through hole, arcwall and connecting base, through hole and the coaxial setting of hinging hole, and arcwall and boss cambered surface are inconsistent.

Described dowelled spanner is provided with special-shaped bar and circular pin, and circular pin is arranged on the termination of special-shaped bar, and the shape of special-shaped bar and profiled holes is complementary, and circular pin is installed in aperture, and after special-shaped bar passed profiled holes, the boss deck can rotate with dowelled spanner.

Described limited wall has limited hinged seat and has rotated towards a direction; After the rotating position spanner, the boss deck rotates with dowelled spanner, when the boss cambered surface and arcwall inconsistent after, limited hinged seat and rotated to another way, this moment, the degrees of freedom of hinged seat was zero, reached firm support rotating.

The beneficial effects of the utility model are: hinged seat is hinged by rivet and fixed base, limited wall has limited hinged seat and has rotated towards a direction, be provided with the boss deck in hinged seat one side, the boss deck rotates with dowelled spanner, until after boss cambered surface and arcwall, limited the rotation of hinged seat towards the another one direction, make hinged seat reach the locking and positioning state, after the rotating position spanner makes the boss cambered surface and arcwall separates, hinged seat can rotate towards a direction around fixed base, reaches free rotary state; Therefore, the utlity model has characteristics simple in structure, easy to operate and that be suitable as the accessory uses such as furniture.

Embodiment

Below by specific embodiment, and by reference to the accompanying drawings the technical solution of the utility model is described further.

Embodiment: with reference to Fig. 1, a kind of hinged detent of furniture, it comprises fixed base 1, boss deck 2, hinged seat 3, dowelled spanner 4, rivet 5; It is characterized in that boss deck 2 is hinged by dowelled spanner 4 and fixed base 1; Hinged seat 3 is hinged by rivet 5 and fixed base 1.

With reference to Fig. 2, described fixed base 1 is provided with macropore 11, hinging hole 12, aperture 13, limited wall 14, and macropore 11 is coaxial setting with aperture 13, and hinging hole 12 is arranged on a side in macropore 11 and aperture 13 axle center, place, and limited wall 14 is arranged on a side of hinging hole 12.

With reference to Fig. 3, described boss deck 2 is provided with profiled holes 21 and boss cambered surface 22, profiled holes 21 and macropore 11 and the coaxial setting of aperture 13.

With reference to Fig. 4, described hinged seat 3 is provided with through hole 31, arcwall 32 and connecting base 33, through hole 31 and the coaxial setting of hinging hole 12, and arcwall 32 is inconsistent with boss cambered surface 22.

With reference to Fig. 5, described dowelled spanner 4 is provided with special-shaped bar 41 and circular pin 42, and circular pin 42 is arranged on the termination of special-shaped bar 41, and special-shaped bar 41 is complementary with the shape of profiled holes 21, and circular pin 42 is installed in aperture 13.

With reference to Fig. 6, during use, fixed base 1 is installed on matrix 7 by screw 6, and hinged seat 3 is hinged by rivet 5 and fixed base 1, a lateral confinement system of fixed base 1 hinged seat 3 clockwise rotate, when driving boss deck 2, rotating position spanner 4 rotates, rotate counterclockwise until boss deck 2 has limited hinged seat 3, at this moment, hinged seat 3 has reached locking state, metallic support pipe 8 is fixed on hinged seat 3, makes hinged seat 3 and metallic support pipe 8 reach the positioning supports state.
