The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.As shown in Figure 1, the plummer 1 of the indoor bay-lift structure of the utility model uses the rack-and-gear type of drive, drives with 24 volts of DC machine; DC machine has Electronic Protection; the lifting of available remote control equipment (RCE) control bay-lift also can be adopted manual mode, volume I flexible combination.

As shown in Figure 2, gear 2 tooth bars 3 adopt plastic gear 2 and plastics tooth bar 3, and the friction during transmission between gear 2 and the tooth bar 3 does not have sound, and is quiet, and plastics tooth bar 3 can prolong as required.

As shown in Figure 3, the core of tooth bar 3 is provided with metal shaft 4 along its length, increases the intensity of tooth bar 3, to bear big pressure.

As shown in Figure 4, no matter manual mode or electronic mode all are furnished with braking mechanism, make bay-lift stay in some height for a long time under passive situation, do not glide.Braking mechanism comprises a brake gear 5 that tooth is arranged, utilize the toothed brake linkage 6 of an end, add the effect of upper reset spring 7, brake linkage 6 is meshed with brake gear 5, the other end of brake linkage 6 connects with the mouth 8 of brake engine installation, normally stopping situation, the tooth of brake linkage 6 one ends is meshed with brake gear 5, make brake gear 5 static, when rising or during the decline bay-lift, brake linkage 6 utilizes motor or manually promotes brake linkage 6 and breaks away from brake gear 5, the rotating shaft of gear 2 thereby freedom, and bay-lift just can freely move up and down.

The design of rack-and-gear can be adopted several different designs combinations, as shown in Figure 5 because of the Item Weight difference of bay-lift carrying, light-duty formula, two pairs of gear 2 tooth bars 3 are positioned at the homonymy of plummer 1, and opposite side is provided with a pair of sliding rail, and gear 2 lays respectively at the outside of two tooth bars 3.

As shown in Figure 6, standard form, four synchronizer gears 2 cooperate four toothed rack 3, and tooth bar 3 is two groups, and two is one group, is positioned at the relative both sides of plummer 1, and gear 2 lays respectively at two tooth bars, 3 inboards, and this design is applicable to that the very narrow bay-lift in space uses.

As shown in Figure 1, four synchronizer gears 2 cooperate four toothed rack 3, tooth bar 3 is two groups, and two is one group, is positioned at the relative both sides of plummer 1, gear 2 lays respectively at two tooth bars, 3 outsides, this is the design of safety, is subjected to external impacts in gear 2 accidents, after impaired the breaking of gear 2 bodies, elevator still can be clipped on the tooth bar 3, and bay-lift can not fallen down.

As shown in Figure 7, gravity-type, cooperate eight toothed rack 3 or four two-sided tooth bars 3 to combine with eight gears 2, divide two groups of relative both sides that are arranged on plummer, the design of bidentate wheel is safe and the strongest a kind of design, two groups of gears 2 clip one group of two-sided tooth bar 3 simultaneously, two gears, 2 relative fixed, the situation of slip teeth can occur hardly, can bear bigger weight and out-of-balance force with the bay-lift of this method arrangement.

As shown in Figure 8, all gears all are provided with guard shield 9, make the staff can not the striking gear, are the important rings of bay-lift.

As shown in Figure 9; motor is provided with temperature protection switch 10 or Thermal Cutoffs 11; when motor 12 operating temperatures are spent above 60; motor 12 stops automatically; and whole machine also enters dormant state; wait motor cooling, this device are to prevent that people are placed on overweight object on the bay-lift and do not stop lifting back and forth, make the 12 temperature rising of bay-lift overload motor and can cut off the electricity supply automatically.

As shown in figure 10, motor type bay-lift all is provided with upper stroke switch 13 and lower stroke switch 14, and switch will be cut off the electricity supply when bay-lift is gone to top dead point or bottom dead point, allows bay-lift stop.

The entire circuit of motor type bay-lift also is provided with an electronic time controller, and time set is the travel time of whole machine, and when the capable intact one stroke of each bay-lift, time system is stopped power supply automatically.Arranged until next time people's Push switch just automatic zero set (AZS), from the beginning computing time again.This device is exempted from people and is forgotten and close electricity and bay-lift to be subjected to external force stuck, under the situation of being unable to stir any more, still only allows and has only a travel time just to cut off the electricity supply.
