Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1, Figure 2 and Figure 3, give the structural representation of the solid of Biohazard Safety Equipment easy to clean of the present invention, left view and top view, it comprises cabinet 1, front window frame 2, front screen 3, air spring support 4, rotating shaft 5, lifting motor 6, power transmission shaft 7, holder 8, steel wire drive wheel 9, traction steel wire 10, balancing weight 11, balancing weight guide rail 12; Shown cabinet 1 is fixed and supporting role, and the inside of cabinet 1 is provided with biological experiment operating district, to carry out relevant Bioexperiment.
Shown front window frame 2 is arranged at the front portion of cabinet 1 rotationally by rotating shaft 5, front screen 3 is arranged among front window frame 2; When front window frame 2 is in closure state, front screen 3 can carry out elevating movement.The both sides of front window frame 2 are provided with air spring and support 4, to be located at suitable angle when current window frame 2 lifts.Lifting motor 6, power transmission shaft 7 and holder 8 are arranged at the top of cabinet 1, and power transmission shaft 7, steel wire drive wheel 9, traction steel wire 10 and balancing weight 11 constitute transmission mechanism, and lifting motor 6 can order about front screen 3 and carry out elevating movement under transmission mechanism effect.As shown in Figure 4 and Figure 5, sets forth the partial enlarged drawing in a-quadrant and B region in Fig. 1, it also comprises driving pulley 13, driven pulley 14 and directive wheel 15.
Lifting motor 6 is fixed on the upper surface of cabinet 1, and power transmission shaft 7 is fixed on the upper surface of cabinet 1 by four holders 8.Driving pulley 13 fixes with the output shaft of lifting motor 6, and driven pulley 14 is fixed on power transmission shaft 7, and driving pulley 13 is connected by driving-belt with driven pulley 14.Two steel wire drive wheels 9 are arranged at the two ends of power transmission shaft 7, and traction steel wire 10 is wrapped on steel wire turning cylinder 9, and the two ends of traction steel wire 10 fix with balancing weight 11 and front screen 3 respectively.Balancing weight 11 is positioned at the rear of cabinet 1, and the two balancing weight guide rails 12 be arranged in parallel realize the guide effect to balancing weight 11.Like this, lifting motor 6 orders about front screen 3 and carries out lifting action under the effect of balancing weight 11, can effectively reduce the Power output of lifting motor 6.
In order to when ensureing that front window frame 2 is lifted, front screen 3 can not carry out lifting action, the C region of window frame 2 is also provided with locking device before shown in Fig. 2, is provided with locking device at the two ends of front window frame 2.As shown in Fig. 6, Fig. 7 and Fig. 8, give the structural representation of locking device, it comprises locking button 17, locking hook 19, stop nut 21, back-moving spring 22, retainer ring 23, glass solder block 24; Shown glass solder block 24 is fixed on the side of front screen 3 bottom, and locking button 17 is arranged on the side of front window frame 2, realizes the position-limiting action to glass solder block 24.Locking hook 19 and locking pin 20 are all arranged on front window frame 2 and also can move along the lifting direction of front screen 3.The two ends up and down of locking pin 20 are respectively arranged with back-moving spring 22 and stop nut 21, and back-moving spring 22 realizes the reset response of locking pin 20, and stop nut 21 realizes the position-limiting action of locking pin 20 movement.Retainer ring 23 is fixed on cabinet 1, for realizing and locking coordinating of hook 19.
When before front screen 3 is not fallen when window frame 2 minimum point, glass solder block 24 does not contact with locking hook 19, locking hook 19 extend among the cavity of retainer ring 23 under the effect of back-moving spring 22, realize the position-limiting action to front window frame 2, now, front screen 3 can carry out lifting action under the effect of lifting motor 6.When current window glass 3 drops down onto minimum point, undertaken spacing by locking button 17 pairs of glass solder blocks 24, the state of locking button 17 as shown in figures 6 and 7, now lock hook 19 to be separated with retainer ring 23, front window frame 2 can carry out free rotation, and front screen 3 is owing to locking the position-limiting action of button 17, elevating movement can not be carried out.Therefore, achieve by locking device the interlocking that front window frame 2 lifts action and front screen 3 lifting action.
For the ease of front screen 3 elevating movement manually can be ordered about in the power-off state, be fixed with handle 16 in the lower end of front screen 3.Cabinet 1 is also provided with power switch 18.
The Biohazard Safety Equipment easy to clean that electric and hand of the present invention combines, front screen 3 elevating mechanism adopts electric up-down mode, adopts driven by motor synchronizing wheel to pull the mode of steel wire rope, drives counterweight to rise simultaneously or declines, realizing front screen move up and down with this.Lifting motor 6 machine distinguishing feature is that after power-off, spline moment is very little, drags front glass window handle can close front glass window with hand.Front screen 3, for manually to lift mode, supports 4 by air spring after lifting and supports.When current glass window 3 lifts, before closed, front screen 3 fixed by the locking button 17 of window frame, and front screen 3 is rotated with fixed border.
Biohazard Safety Equipment of the present invention, not only achieves the automatic lifting of front screen, is convenient to Biohazard Safety Equipment and carries out test operation.And front window frame can be in open mode easily, be convenient to clean the inner surface of front screen, ensure that the clean of biological experiment operating district.By locking device, achieve front screen and be elevated the interlocking of lifting action with front window frame, when making only have front screen to fall minimum point and be lockable, front screen just can be ordered about lifting, the security that the equipment that ensure that runs.
