Specific embodiments
Below in conjunction with Figure of description and embodiment, specific embodiments of the invention are described in further detail:
With reference to a kind of cabinet door locking mechanism being applicable to bedpan cleaning machine shown in Fig. 1 ~ Fig. 2, comprise mechanism's fixed head 1, be arranged on the electric pushrod 2 on described mechanism fixed head 1, also comprise the fanning strip 3 be arranged on described mechanism fixed head 1, in the present embodiment, above-mentioned fixed head 1 is the Special fixing plate that electric pushrod 2 is fixed on inside body, the object of such design is, when this is applicable to the cabinet door locking mechanism action of bedpan cleaning machine, marry again on this fixed head by the active force of electric pushrod 2 pairs of cabinet door external shells, thus outer shell body deformability can not be caused, or get up to have obvious action from the appearance, wherein, this fanning strip 3 is sheet metal component, and the object of design is like this, is convenient to processing, reduce manufacture difficulty, there is intensity simultaneously high, the advantages such as long service life, and described fanning strip 3 is provided with deep-slotted chip breaker 3-1, the object of such design is, be convenient to match with fanning strip 3, this deep-slotted chip breaker 3-1 is also the first limited post 11 and the second limited post 12 for installing in following position-limit mechanism simultaneously, thus makes above-mentioned fanning strip 3 do arc sliding motion, the end of the locking expansion link 4 of described electric pushrod 2 can adopt bolt etc. to be fixed on described fanning strip 3, electric pushrod 2 is made to stablize with fanning strip 3, reliably be connected like this, when locking expansion link 4 action of above-mentioned electric pushrod 2, can be the arcuate movement driving fanning strip 3 by the translate linear motion of locking expansion link 4, when locking expansion link 4 return, then drive fanning strip 3 to do arcuate movement in contrast by the rectilinear motion of locking expansion link 4, make this fanning strip 3 return equally, described fanning strip 3 is connected with one end of door brace 6 by kinematic link 5, and the other end of described door brace 6 is connected with door 8 by door pivot 7, in the present embodiment, one end of described kinematic link 5 is flexibly connected with described fanning strip 3, and the other end of described kinematic link 5 is fixedly connected with described door brace 6 by bolt 9.In the present embodiment, above-mentioned kinematic link 5 plays gearing, first rectilinear motion is done by the locking expansion link 4 of electric pushrod 2, thus drive the fanning strip 3 be attached thereto to do arcuate movement, owing to being be flexibly connected between fanning strip 3 with this kinematic link 5, therefore while fanning strip 3 does arcuate movement, kinematic link 5 has been driven again to twist, due between kinematic link 5 with door brace 6 for bolt is fixedly connected with, also correspondingly while kinematic link 5 action door brace 6 action has been driven, finally because the other end of door brace 6 is connected with door 8 by door pivot 7, like this when 6 action of door brace, the action of opening or closing of final realization door 8.In the present embodiment, in said mechanism, have employed fanning strip 3 and kinematic link 5, compared with conventional art, add connecting rod quantity, transform thrust well by fanning strip 3 and middle kinematic link 5, the simultaneously stability twisting of push rod itself, thus effectively improve this cabinet door locking mechanism being applicable to bedpan cleaning machine and opening and the reliability in conjunction process and safety, and flexible movements are reliable, long service life.
With reference to Fig. 1, Fig. 2, described in be applicable to bedpan cleaning machine cabinet door locking mechanism also comprise the position-limit mechanism be arranged on described mechanism fixed head 1, described position-limit mechanism comprises electronic limit mechanism and mechanical position limitation mechanism, wherein, described electronic limit mechanism is microswitch 10, and described microswitch 10 is arranged on the plate edge place of described fanning strip 3, the object of such design is, when fanning strip 3 rotates, trigger microswitch 10 by the projection at plate edge place, thus the signal of telecommunication is sent to machine, door and normal folding, in the conventional technology, have employed two microswitches and carry out spacing, and in this mechanism, use only an above-mentioned microswitch and just can reach spacing effect, therefore save cost, described mechanical position limitation mechanism comprises the first limited post 11 and the second limited post 12 be arranged in described deep-slotted chip breaker 3-1, wherein, above-mentioned first limited post 11 and the second limited post 12 interval are arranged, be separately positioned on the two ends in deep-slotted chip breaker 3-1, when fanning strip 3 does arcuate movement around deep-slotted chip breaker 3-1, by being arranged on the first limited post 11 and the second limited post 12 in this deep-slotted chip breaker 3-1, thus can position-limiting action be played, i.e. and first limited post 11 and second limited post 12 interior by the deep-slotted chip breaker 3-1 on fanning strip 3, thus the size of the cabinet door locking mechanism folding being applicable to bedpan cleaning machine can be limited, and prevent this mechanism kinematic locked to motion dead band, in the present embodiment, the object of design is like this, when above-mentioned microswitch 10 lost efficacy, is then undertaken second heavy spacing by two mechanical position limitation points of the first limited post 11 and the second limited post 12.In this cabinet door locking, adopt above-mentioned two kinds of position-limit mechanisms spacing to carry out, compared with traditional mechanism, adopt double limitation, effectively ensure that this is applicable to the reliability of the cabinet door locking mechanism kinematic of bedpan cleaning machine.
The operating principle of the present embodiment: first, when electric pushrod 2 stretches out, by locking expansion link 4 drive fanning strip 3 arcuately groove 3-1 rotate counterclockwise, the movable end that now fanning strip 3 is connected with kinematic link 5 is turned right and is moved, thus kinematic link 5 is moved upward, drive door brace 6 to move, door brace 6 turns clockwise around the door pivot 7 be fixed on door 8, namely opens the door; Secondly, when electric pushrod 2 is retracted, by locking expansion link 4 drive fanning strip 3 arcuately groove 3-1 rotate clockwise, now the movable end that is connected with kinematic link 5 of fanning strip 3 is toward left movement, thus kinematic link 5 is moved downward, drive door brace 6 to move, door brace 6 is rotated counterclockwise around the door pivot 7 be fixed on door 8, namely closes the door.
In sum, this cabinet door locking mechanism being applicable to bedpan cleaning machine connects fan-shaped sheet metal member by electric pushrod, the reciprocating motion of electric pushrod is converted to arcuate movement, thus drive kinematic link to move, drive door brace again, make rotating shaft axle in Men Yimen be that axle center rotates, realize the folding of door in cleaning machine, and ensure that the stability of Movement transmit; Simultaneously by the deep-slotted chip breaker on fan-shaped sheet metal component and two limited posts, limit the size of a folding and to prevent mechanism kinematic from arriving motion dead band locked; And only adopt a microswitch, cost-saving.
The above, it is only preferred embodiment of the present invention, not any restriction is made to technical scope of the present invention, thus every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalent variations and modification, all still belong in the scope of technical scheme of the present invention.
