Abstract
The utility model discloses a novel multifunctional fitness chair backrest resetting mechanism. The novel multifunctional fitness chair backrest resetting mechanism comprises a support assembly of a multifunctional fitness chair and a backrest mechanism which is pivoted to the support assembly through pins; an elasticity device is arranged between the support assembly and the backrest mechanism; one end of the elasticity device is pivoted to the support assembly; the other end of the elasticity device is pivoted to the backrest mechanism; a spring, an elastic piece and the like can be served as the elasticity device in a practical application process. According to the novel multifunctional fitness chair backrest resetting mechanism, the backrest mechanism can distort the elasticity device when rotating downward around the pins, so that the elasticity device generates the restoring force to the backrest mechanism and the backrest mechanism can automatically reset. The novel multifunctional fitness chair backrest resetting mechanism has the advantages of being simple and reasonable in integral mechanism, small in occupied space, not easy to clamp hands and safe and reliable.
Description
Technical field
The utility model relates to a kind of Multifunction ab lounge backrest resetting-mechanism.
Background technology
Along with social development, people's rhythm of life is accelerated gradually, the time of modern urbanite's outdoor exercises is fewer and feweri, the various physical problems that thereupon occur are as physical stamina letdown, resistance lowers, fat etc., for addressing this problem, occurred now much can being placed on indoor sports equipment for people, as comparatively common multifunctional body-building chair, people can sway one's hips on multifunctional body-building chair, sleeping lifting the dumbbell, sit-ups, the motion that push-up etc. are multiple, people's back comfortableness while carrying out sit-ups for being increased in, conventionally multifunctional body-building chair can configure a backrest, this backrest can rotate and can automatically reset, yet traditional resetting-mechanism normally adopts the modes such as extension spring to reset, extension spring need to be reserved certain stretching space so that it elongates, therefore its space taking is larger, and while elongating, easily clip to staff.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of simple in structure, take up room Multifunction ab lounge backrest resetting-mechanism little, safe.
The utility model solves the technical scheme that its technical problem adopts:
A kind of Multifunction ab lounge backrest resetting-mechanism, comprise a multifunctional body-building chair bracket component, by a pin be articulated in the backrest on bracket component and be arranged on bracket component and backrest between elastic force apparatus, described elastic force apparatus one end is articulated on bracket component, its other end is hinged on backrest, can distortion elastic force apparatus when pin rotates when backrest and make elastic force apparatus produce restoring force to backrest.
Described elastic force apparatus is comprised of the spring of at least one.
Described elastic force apparatus is comprised of the shell fragment of at least one.
On described backrest, be provided with an inverted U-shaped fastener being buckled on elastic force apparatus.
The extension of described backrest lower end is provided with a limiting section, is provided with the limited block corresponding with this limiting section on described bracket component.
On described limited block, be provided with cushion pad.
The beneficial effects of the utility model are: between bracket component and backrest, be provided with elastic force apparatus, elastic force apparatus one end is articulated on bracket component, its other end is hinged on backrest, at actual application elastic force device, can adopt spring, shell fragment etc., can distortion elastic force apparatus when pin rotates when backrest and make elastic force apparatus produce restoring force to backrest, thereby backrest can be resetted automatically, the structure of whole mechanism, advantages of simple, and the space taking is little, be difficult for clipping to staff, safe and reliable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is one of overall structure schematic diagram of the present utility model;
Fig. 2 is two of overall structure schematic diagram of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 1, Fig. 2 is the structural representation of a specific embodiment of the utility model, as shown in the figure, a kind of Multifunction ab lounge backrest resetting-mechanism, the bracket component 1 that comprises a multifunctional body-building chair, by a pin 11 be articulated in the backrest 2 on bracket component 1 and be arranged on bracket component 1 and backrest 2 between elastic force apparatus, this elastic force apparatus is a spring 3 in the present embodiment, certainly in the concrete process of implementing, also can adopt shell fragment, a plurality of spring assemblies, a plurality of modes such as shell fragment combination, described spring 3 one end are articulated on bracket component 1, its other end is hinged on backrest 2 rears, on backrest 2, be provided with an inverted U-shaped fastener 21 being buckled on spring 3, the distortion of restraining spring 3, when backrest 2 is when pin 11 rotates, under the restriction of inverted U-shaped fastener 21, spring 3 flexural deformations, and backrest 2 is produced to restoring force, when unclamping downforce, backrest 2 can reset automatically, realize the reset function of backrest 2, the structure of whole mechanism, advantages of simple, and the space taking is little, be difficult for clipping to staff, safe and reliable.
As shown in the figure, described backrest 2 lower ends extensions are provided with a limiting section 22, on described bracket component 1, be provided with the limited block corresponding with this limiting section 22 12, when backrest 2 resets to certain angle, limiting section 22 is pressed on limited block 12, realizes spacing function, in addition, on this limited block 12, be also provided with cushion pad, play cushioning effect, prevent that limiting section 22 from directly clashing into limited block 12.
More than that better enforcement of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the distortion that these are equal to or replacement are all included in the application's claim limited range.
