Detailed description of the invention

Core of the present utility model is in that to provide a kind of long service life, and simple in construction, the height adjustable seat maintained easily, for various body-building apparatus.

In order to make those skilled in the art be more fully understood that technical scheme, height adjustable seat this utility model designed below in conjunction with accompanying drawing and specific embodiment is described in detail.

As in figure 2 it is shown, structural relation figure, Fig. 3 for a kind of height adjustable seat of this utility model offer are the outside overall structure figure being arranged in a kind of exercising apparatus.There is a seat cushion 1, take for user, be fixedly installed rotating turret 2 in the bottom of seat cushion 1, rotating turret 2 seat cushion 1 supported from below. One end of rotating turret 2 is fixed with seat cushion 1, and the other end is hinged on bearing 3, and rotating turret 2 can rotate by the hinge on bearing 3, drives seat cushion 1 synchronous axial system, and rotating shaft is horizontally disposed with, and makes seat cushion 1 rotate up and down in vertical plane, thus realizing the adjustment of height. Rotating turret 2 is provided with adjustment handle 21, regulates handle 21 and may be provided at the underface of seat cushion 1, against the bottom of seat cushion 1, in the position that user arm can touch, conveniently move adjustment. Regulating handle 21 and be rotationally connected with on rotating turret 2, be additionally provided with bolt axle 22 on rotating turret 2, one end of bolt axle 22 is rotationally connected with regulating handle 21, and the other end can slide on rotating turret 2. Being further fixedly arranged on adjustment seat 4 on bearing 3, the end portion of bolt axle 22 sliding end can be inserted in adjustment seat 4, when after bolt axle 22 with adjustment seat 4 secure fit, it is possible to rotating turret 2 is played a supporting role, thus seat cushion 1 is positioned support.

Seat cushion 1 is supported by the rotating turret 2 arranged by rotation in this utility model, and by the height of the up and down motion regulating seat cushion 1 of rotating turret 2, rotating turret 2 is provided support force by bolt axle 22, bolt axle 22 inserts in adjustment seat 4 behind relevant position, axial to rotating turret 2 applied thrust along bolt axle 22, is supported from below. Owing to have employed mechanical structure, therefore having longer service life compared to the supporting construction of air-cylinder type, the parts that whole device has are also less, structure can be simplified, relative to four-bar linkage structure, the requirement of precision is not significantly high, facilitate the manufacturing, reduce production cost.

Hinged on rotating turret 2 can arranging rotation bar 5 to realize better support effect, the one end rotating bar 5 is connected with rotating turret 2, and the other end is hinged with bearing 3, rotates bar 5 and rotates on bearing 3 rotating around respective hinge with rotating turret 2. Rotate arranging of bar 5 and can improve the stability that rotating turret 2 rotates, restriction effect better can be reached when regulating. And rotate bar 5 and be set to two, two rotation bars 5 lay respectively at the both sides of bearing 3 and the both sides of rotating turret 2. Two the rotation bars 5 being connected on bearing 3 when rotating are connected to same rotating shaft, and the rotation bar 5 being connected on rotating turret 2 is connected to same rotating shaft, makes two rotation bars 5 reach synchronous axial system.

In order to user when being adjusted up seat lighter, scroll spring can be set at the hinge place rotated between bar 5 and bearing 3, scroll spring can produce moment of torsion to rotating bar 5, thus rotating turret 2 is applied active force upwards, user owing to the auxiliary of scroll spring can be easier to lift, facilitates adjustment when being adjusted up; And owing to the action of gravity of seat cushion 1 self has the trend moved downward when needing to regulate downwards, also can conveniently adjust.

Bolt axle 22 needs to slide on rotating turret 2, is driven bolt axle 22 axially-movable by regulating handle 21, more smoothly in order to make bolt axle 22 move, and can arrange sleeve pipe 23 on rotating turret 2. Sleeve pipe 23 and rotating turret 2 being fixed, bolt axle 22 may be inserted in sleeve pipe 23, and the both sides of sleeve pipe 23 are run through, and bolt axle 22 inserts from one end and passes from the other end, can inject in the hole, location in adjustment seat 4, thus realizing the positioning action of differing heights after prominent. It is provided with and sleeve pipe 3 can allow the motion of bolt axle 22 more smooth, and bolt axle 22 can be made more to enter precisely in adjustment seat 4 and position in hole.

Specifically, rotating turret 2 is set to the shell structure of inner hollow, rotate bar 5 and be hinged on outside the upright side walls of housing both sides, two blocks of fixing plates it are vertically arranged between two upright side walls, fixing plate has the perforate of card tubing 23, sleeve pipe 23 is fixed on rotating turret 2 by fixing plate, sleeve pipe 23 and rotating turret 2 common rotation.

Sleeve pipe 23 rotates along with rotating turret 2, in order to realize and bolt axle 22 corresponding matching in sleeve pipe 23, adjustment seat 4 is set to the platy structure of arch, the two ends of arch are fixed by bolt and bearing 3, plate face arranges multiple through hole corresponding with bolt axle 22 shape, the rotary motion trace of sleeve pipe 23 end and the shape corresponding matching in adjustment seat 4 plate face, make rotating turret 2 no matter turn to what angle and can make bolt axle 22 corresponding reeve adjustment seat 4.

In order to facilitate manual adjustments, can being arranged to bent angle shape by regulating handle 21, apex and rotating turret 2 are hinged setting, the one end regulating handle 21 is moved for staff, the other end installs spring 211, and spring 211 is also connected with rotating turret 2, applies pulling force to regulating handle 21. Structure in accompanying drawing, upwards moves adjustment handle 21 when regulating, and driving bolt axle 22 to extract out, making adjustment handle 21 rotate, thus being re-inserted in adjustment seat 4 by bolt axle 22 after regulating height under the drive of spring 211, it is achieved spacing fixing.

In order to strengthen rotating the intensity of bar 5, tabular can be set to by rotating bar 5, along vertically setting. In order to coordinate better with rotating turret 2 when making the rotation of rotation bar 5, rotating bar 5 and be set to the flat board of obtuse angle shape, the drift angle at obtuse angle is downward.

Height adjustable seat in this utility model, drives seat cushion about 1 to rotate owing to rotating 2, two rotation bars 5 of bar jointly, and regulating seat cushion 1 is in differing heights. More laborsaving by rotating when the scroll spring arranged between bar 5 and bearing 3 provides the thrust of auxiliary to make adjustment. Relative to four-bar linkage structure, the structure in this programme is simpler, therefore can simplify production process, makes the precision of installation reduce, and reduces production cost.

Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this utility model. The multiple amendment of these embodiments be will be apparent from for those skilled in the art, generic principles defined herein, it is possible to when without departing from spirit or scope of the present utility model, realize in other embodiments. Therefore, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
