Description
Technical field
The present invention relates to body-building apparatus technical field, especially relate to a kind of can stable regulation after the abdominal boards of plate.
Background technology
Abdominal boards is extremely welcome body-building apparatus at present.Conventionally, this abdominal boards comprises the side arm, the after-frame that link together.This side arm is provided with support bar and pin raker, and the front portion of this after-frame is horizontal, rear portion is skewed, and on the front portion of this after-frame, be fixed with horizontal header board, rear portion is provided with the rear plate with certain inclination angle.In use, person taking exercise is sitting on this header board, leans against rear plate, and meanwhile, person taking exercise's huckle is subject to the support of support bar, and ankle portion hooks on pin raker, can repeatedly carry out sit-up exercise.After further developing, in order to meet different person taking exercises' needs, or for the needs that regulate exercise intensity, the inclination angle of this rear plate can be adjusted.But, be that rear plate increases after angle regulator, this rear plate is often stable not, thereby makes person taking exercise feel comfortable not.
Summary of the invention
The object of this invention is to provide a kind of can stable regulation after the abdominal boards of plate, it is comparatively stable that it has the time of use, thus person taking exercise feels comparatively comfortable feature.
The technical solution adopted in the present invention is: the abdominal boards of plate after can stable regulation, comprise rear plate and the side arm linking together, after-frame, wherein, this side arm is provided with support bar and pin raker, the front portion of this after-frame is horizontal, it is skewed that rear portion is, and on the front portion of this after-frame, be fixed with horizontal header board, the front end of described rear plate is hinged at the middle part of this after-frame, and the middle lower portion of this rear plate is hinged with rigidity connecting rod, the lower end of this rigidity connecting rod is hinged with sliding sleeve, simultaneously, this after-frame adopts tubing preparation, on the rear portion that is sheathed on this after-frame of this sliding sleeve matched in clearance, and, this sliding sleeve is provided with elasticity pin, the rear portion of this rear bar is provided with at least 2 adjustment holes that match with this elasticity pin.
The section of described after-frame is track type.
The advantage that the present invention has is: comparatively stable when use, and comparatively comfortable thereby person taking exercise feels.Of the present invention can stable regulation after the abdominal boards of plate support by this rear plate of a rigid connecting pole pair, simultaneously, thereby the slip that is enclosed within this sliding sleeve on this after-frame that is used for the sliding sleeve matched in clearance that supports this rigidity connecting rod is comparatively stable, and after elasticity pin is inserted in adjustment hole, this sliding sleeve cannot move, and then this rear plate, rigidity connecting rod, after-frame form comparatively stable triangular structure all the time.Like this, make person taking exercise feel comparatively comfortable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the front view (broken section) of embodiments of the invention;
Fig. 2 is the A portion enlarged drawing of Fig. 1.
The specific embodiment
Embodiment, is shown in shown in Fig. 1 and Fig. 2: the abdominal boards of plate after can stable regulation, comprise rear plate 50 and the side arm 11 linking together, after-frame 12, this side arm 11 and after-frame 12 can be integrative-structures.Wherein, this side arm 11 is provided with support bar 20 and pin raker 30, and the front portion 121 of this after-frame 12 is horizontal, rear portion 122 is skewed, and is fixed with horizontal header board 40 on the front portion 121 of this after-frame 12.Further say, the front end of this rear plate 50 is hinged at the middle part of this after-frame 12.Such as the front end of this rear plate 50 is hinged at the front portion 121 of this after-frame 12 and the joint portion at rear portion 122.And the middle lower portion of this rear plate 50 is hinged with rigidity connecting rod 60, the lower end of this rigidity connecting rod 60 is hinged with sliding sleeve 70.Meanwhile, this after-frame 12 adopts tubing preparation, on the rear portion that is sheathed on this after-frame 12 122 of these sliding sleeve 70 matched in clearance.And this sliding sleeve 70 is provided with elasticity pin 71, the rear portion 122 of this rear bar 12 is provided with at least 2 adjustment holes 1221 that match with this elasticity pin 71.Thereby so-called elasticity pin 71 refers to and is connected with back-moving spring and can be inserted in voluntarily in this adjustment hole 1221, and can be imposed the pin being pulled out after pulling force by user.Such as, the inner of this elasticity pin 71 can be inserted in this adjustment hole 1221, the outer end of this elasticity pin 71 is provided with to be convenient to user and to extract the ballhead of this elasticity pin 71, and on this elasticity pin 71, is arranged with the stage clip that makes this elasticity pin 71 have inside reset trend.Like this, this rear plate 50, this rigidity connecting rod 60, this after-frame 12 form comparatively stable triangular structure all the time, thereby this rear plate 50 is comparatively stable all the time, make person taking exercise feel comparatively comfortable.
Further say, the section of this after-frame 12 is track type.Certainly, the inner chamber section of sliding sleeve 70 now is also track type.Like this, make the slip of this sliding sleeve 70 more smooth and steady.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
