In order to overcome the deficiencies in the prior art, the invention provides a kind of hinged detent of pin pipe, can structure be simplified, easy to operate and eliminate safe hidden trouble.
The technical solution adopted in the present invention is: a kind of hinged detent of pin pipe, and it comprises fixed base, end cap, spring, slide block, hinged seat, rivet; It is characterized in that spring is arranged between end cap and slide block, end cap is fixed on hinged seat, and slide block is arranged in hinged seat, and hinged seat is hinged by rivet and fixed base.
Described fixed base is provided with hinging hole, positioning hole, locating notch, locating slot, limited wall; Hinging hole can be installed rivet and rivet mutually with hinged seat, the shape of locating slot and the mating shapes of hinged seat.
Described end cap is provided with locating column, boss post, screw hole; Locating column installs spring, guide support is played to spring, in boss post, be provided with screw hole.
Described slide block is provided with guiding groove, plane boss, groove; Guiding groove is arranged on the periphery of slide block, and plane boss is arranged on the center of slide block, and plane boss is used for supported spring, is provided with groove below plane boss, and groove is semicircle, matches with the external diameter of rivet.
Described hinged seat is provided with slotted hole, directional post, location counterbore, positioning boss, link arm; Rivet can slippage in slotted hole, and the guiding groove on slide block is installed on directional post, makes slide block can along directional post slippage, boss post is installed in the counterbore of location, be fixed together by screw, positioning boss and locating notch fasten, and link arm is used for connecting pin pipe.
The invention has the beneficial effects as follows: spring is installed between slide block and end cap, end cap is fixed on hinged seat, hinged seat is hinged by rivet and fixed base, is installed in by hinged seat in the locating slot on fixed base, can realizes the positioning supports of hinged seat, when needing to turn folding, only need pull hinged seat, make rivet promote slide block Compress Spring, spring is shortened by compression, thus hinged seat is spun off in locating slot, hinged seat can realize free rotation; Therefore, to have structure simple, easy to operate and be suitable as the feature that the accessory such as furniture uses in the present invention.

Embodiment
Below by specific embodiment, and by reference to the accompanying drawings technological scheme of the present invention is described further.
Embodiment: with reference to Fig. 1, a kind of hinged detent of pin pipe, it comprises fixed base 1, end cap 2, spring 3, slide block 4, hinged seat 5, rivet 6; It is characterized in that spring 3 is arranged between end cap 2 and slide block 4, end cap 2 is installed on hinged seat 5, and slide block 4 is arranged in hinged seat 5, and hinged seat 5 is hinged by rivet 6 and fixed base 1.
With reference to Fig. 2, described fixed base 1 is provided with hinging hole 11, positioning hole 12, locating notch 13, locating slot 14, limited wall 15; Hinging hole 11 can be installed 6 and rivet with hinged seat 5 phase, the shape of locating slot 14 and the mating shapes of hinged seat 5.
With reference to Fig. 3, described end cap 2 is provided with locating column 21, boss post 22, screw hole 23; Locating column 21 is installed spring 3, guide support is played to spring 3, in boss post 22, be provided with screw hole 23.
With reference to Fig. 4, described slide block 4 is provided with guiding groove 41, plane boss 42, groove 43; Guiding groove 41 is arranged on the periphery of slide block 4, and plane boss 42 is arranged on the center of slide block 4, and plane boss 42 is for supported spring 3, and plane boss 42 is provided with groove 43 below, and groove 43 is semicircle, matches with the external diameter of rivet 6.
With reference to Fig. 5, described hinged seat 5 is provided with slotted hole 51, directional post 52, location counterbore 53, positioning boss 54, link arm 55; Rivet 6 can slippage in slotted hole 51, guiding groove 41 on slide block 4 is installed on directional post 52, makes slide block 4 can along directional post 52 slippage, and boss post 22 is installed in the counterbore 53 of location, be fixed together by screw, positioning boss 54 and locating notch 13 fasten.
