Description
Technical field
The utility model relates to body-building apparatus technical field, specially a kind of sit-ups assistor.
Background technique
Sit-ups assistor is the relatively common instrument in gymnasium, is mainly used for body builder's excercising muscle at abdominal part, at present
Sit-ups assistor is main or large-scale instrument, it is inconvenient that installation is carried, and occurs in the market for this defect some small
The portable sit-ups assistor of type, the sucked type as disclosed in the Chinese patent application No. is 2017216339560 have been lain on the back
Assistor is sat, which has made certain improvement for the simplification of the portability and structure of the equipment, but the skill
Art scheme has the disadvantage that
1, volume waste storage space bigger than normal.
2, the locking of sucker and loosening configuration are excessively complicated, are unfavorable for producing and safeguard.
Utility model content
The purpose of this utility model is that: provide it is a kind of it is portable, save storage space, and simple and reliable for structure lain on the back
Sit assistor.
The purpose of this utility model is achieved through the following technical solutions:
A kind of sit-ups assistor, including pedestal and sucker, pedestal are equipped with bracket, and bracket two sides are equipped with support arm, institute
It states and is equipped with fold mechanism between pedestal and bracket, bracket is compressed or loosened by fold mechanism, driving sucker.
The utility model allows instrument more the advantage is that due to by being equipped with fold mechanism between pedestal and bracket
Good diminution volume can also make bracket by fold mechanism convenient for storage, and driving sucker compresses or loosens, and bracket plays sucker
The effect of switch, simplifies structure, and instrument is made to be more conducive to production maintenance.
In the present invention: the fold mechanism are as follows: the sucker is equipped with sucking disk bar, and sucking disk bar is pierced by pedestal and branch
Frame is hinged on pedestal simultaneously, and the hinge hole of the bracket is less than bottom surface B at a distance from the A of side, is equipped between side A and bottom surface B
Knuckle.Sucking disk bar and bracket are hinged on pedestal simultaneously, sucking disk bar and bracket produce linkage, hinged due to bracket
Hole is less than bottom surface B, bottom surface B and base contacts when bracket is upright at a distance from the A of side, so that bracket hinge hole is in highest order,
Sucking disk bar is driven to increase, to make to generate vacuum compression adsorption plane in sucker；When support-folding, side A and base contacts, make
It obtains bracket hinge hole and is in lowest order, sucking disk bar is driven to reduce, so that vacuum in sucker be made to release release adsorption plane；In side A
It is additionally provided with knuckle between the B of bottom surface, so that the folding of bracket is smoothly transitted with upright state.
In the present invention: the sucker is connect by upper lower sheeting with sucking disk bar, is equipped with and is matched between upper lower sheeting
The seal groove of conjunction.Sucking disk bar can be connect by upper lower sheeting with sucker, and keep sealing by seal groove.
In the present invention: it can also be equipped with seal receptacle in the sucking disk bar bottom, seal receptacle edge is inclined-plane, and
It is matched with the Internal periphery of sucker.When sucking disk bar drive seal receptacle raising can be in true in sucker with Internal periphery tight closure
Sealing is kept when dummy status.
In the present invention: being equipped with power assistant spring between the sucker and pedestal, to the upright of bracket and can fold
Play the role of auxiliary positioning in position.
Compared with prior art, the utility model has the beneficial effects that due to by setting folding between pedestal and bracket
Mechanism folds instrument and is more convenient for storing, and bracket plays the role of sucker switch, driving by fold mechanism
Sucker compresses or loosens, and simplifies structure, and instrument is made to be more conducive to produce and safeguard.

Specific embodiment
Attached drawing 1- attached drawing 4 gives the utility model embodiment.In the present embodiment, sit-ups assistor includes pedestal
1 and sucker 2, pedestal 1 is equipped with bracket 3, and 3 two sides of bracket are equipped with support arm 4, and fold mechanism is equipped between pedestal 1 and bracket 3,
Bracket 3 is compressed or is loosened by fold mechanism, driving sucker 2.The effect that the present embodiment switchs bracket 3 instead of sucker, from
And structure is in turn simplified while reducing and storing volume.The fold mechanism of the present embodiment specifically: sucker 2 is equipped with sucking disk bar 5,
Sucking disk bar 5 is pierced by pedestal 1 and bracket 3 is hinged on simultaneously on pedestal 1, and the hinge hole of the bracket 3 is less than bottom at a distance from the A of side
Face B is equipped with knuckle 6 between side A and bottom surface B.Sucking disk bar 5 and bracket 3 are hinged on pedestal 1 simultaneously, sucking disk bar 5 and branch
Frame 3 produces linkage, since the hinge hole of bracket 3 is less than bottom surface B at a distance from the A of side, bottom surface B and pedestal 1 when bracket 3 is upright
Contact drives sucking disk bar 5 to increase so that the hinge hole of bracket 3 is in highest order, to make to generate vacuum in sucker 2 and compress to inhale
Attached face；When bracket 3 folds, side A is contacted with pedestal 1, so that the hinge hole of bracket 3 is in lowest order, sucking disk bar 5 is driven to drop
It is low, so that vacuum in sucker 2 be made to release release adsorption plane；Knuckle 6 is additionally provided between side A and bottom surface B, so that bracket 3
Folding smoothly transitted with upright state.Sucker 2 is connect by upper tabletting 7 and lower sheeting 8 with sucking disk bar 5, upper lower sheeting
Between be equipped with the seal groove 9 that matches.Sucking disk bar 5 can be connect by upper lower sheeting with sucker 2, and keep sealing by seal groove 9.
Attached drawing 5 gives another sucker structure of the utility model: being equipped with seal receptacle in 5 bottom of sucking disk bar
10,10 edge of seal receptacle is inclined-plane, and is matched with the Internal periphery of sucker 2.It is and interior when sucking disk bar 5 drives seal receptacle 10 to increase
Profile tight closure can keep sealing when sucker 2 is in vacuum state.This technical solution, so that sucker structure more may be used
By simple.
In the present embodiment, can also between the sucker 2 and pedestal 1 be equipped with power assistant spring 11, can be to bracket 3
Play the role of auxiliary positioning in upright and folding position.
Compared with prior art, the utility model has the beneficial effects that due to by setting folding between pedestal 1 and bracket 3
Folded mechanism, folds instrument and reduces volume, be more convenient for storing；And bracket 3 is played sucker and is opened by fold mechanism
The effect of pass, driving sucker 2 compress or loosen, and simplify structure, and instrument is made to be more conducive to produce and safeguard.Above embodiments are only
The case of the utility model, any replacement made according to the spirit of the present invention should be understood as without departing from the utility model
Protection scope.
