Description
Technical field
The utility model relates to a kind of blind lifting protective device, is a kind of blind lifting overload protective device that is built in hollow glass specifically.
Background technology
We know that blind is widely used at present, are used for the built-in electric shutter blind of hollow glass and are also rising gradually.It mainly is to drive winder by a DC speed-reducing by power transmission shaft, and winder drives pull rope, drags blind blades oscilaltion and rotational angle.But the oscilaltion process of existing blind; except that electronic journey is spacing; do not have other protective devices, in case and the reliability of electric machine controller goes wrong, electronic limit is out of control; motor will drive louvre blade and rise to the top; cause blind to promote overload, or damage stay cord, louvre blade, or damage motor; have a strong impact on the use of blind, increased the difficulty and the maintenance cost of maintenance greatly.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art; provide a kind of rational in infrastructure; dependable performance can reduce production costs and maintenance cost greatly, prolongs the blind blind lifting overload protective device that is built in hollow glass in application life.
The technical scheme in the invention for solving the above technical problem is: a kind of blind lifting overload protective device; it is characterized in that: it comprises the driving mandrel; the compound adapter sleeve of power transmission shaft; stage clip; driving mandrel one end is connected with motor output shaft; the other end inserts in the compound adapter sleeve; end face is provided with tooth shape projection disk; compound adapter sleeve is provided with interior cover; regulate overcoat; interior cover is connected with the adjusting sleeve thread; the inner end of interior cover is provided with and drives the chain wheel that mandrel end face tooth shape projection disk matches; the outer end links to each other with the power transmission shaft that drives winder; compression spring sleeve is driving on the mandrel, tooth shape projection disk and regulating between the overcoat inner face in compound adapter sleeve.During operate as normal, drive the tooth shape projection disk of mandrel and the chain wheel of interior cover inner end and be meshing with each other transmission power.
The utility model is owing to adopt the compound adapter sleeve of disengaging type and drive mandrel, and during operate as normal, under the effect of stage clip, the chain wheel that drives mandrel and interior cover is meshing with each other, and moment of torsion transmits by its engages tooth; When the load increase reached to a certain degree, mesh tooth face slided relatively, and chain wheel separates, and realized the overburden protective effect.Against existing technologies, the damage that the utility model has avoided motor, louvre blade, rope to cause owing to runaway electric circuit has prolonged application life of blind product greatly.Improve the blind reliability of products, reduced maintenance cost.The utility model is simple in structure, is convenient to assembling, and running is reliable, can reduce production costs, and increases the service life greatly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. interior covers among the figure, the 1-1. chain wheel, 2. stage clip is 3. regulated overcoat, 4. drives mandrel, 4-1. tooth shape projection disk.
The specific embodiment
As can be seen from Figure 1, a kind of blind lifting overload protective device, it comprises driving mandrel 4, interior cover 1 and regulates the compound adapter sleeve of power transmission shaft of overcoat 3 compositions, stage clip 2 etc.Driving mandrel 4 one ends is connected with motor output shaft, it is to be fixed on the lifting motor output shaft of electric shutter blind, driving mandrel 4 other ends inserts in the compound adapter sleeve, end face is provided with tooth shape projection disk 4-1, cover 1, adjusting overcoat 3 in compound adapter sleeve is provided with, interior cover 1 and adjusting overcoat 3 are threaded, the inner end of interior cover 1 is provided with and drives the chain wheel 1-1 that mandrel 4 end face tooth shapes projection disk 4-1 matches, the outer end links to each other with the power transmission shaft that drives winder, power transmission shaft drives winder, winder drives pull rope, drags the blind blades oscilaltion.Drive the tooth shape projection disk 4-1 of mandrel 4 and the chain wheel 1-1 of interior cover 1 inner end and all have the inclination angle, two tooth shapes projection disk is meshing with each other, like this, the thread form end face that drives mandrel 4 inserts in the thread form end face of interior cover 1, is meshing with each other, under the normal condition, rotating drive mandrel 4, can transmit power, the power transmission shaft that drives winder rotates, and carries out the normal lifting of blind.
The utility model stage clip 2 is enclosed within and drives on the mandrel 4, between protruding disk 4-1 of its tooth shape in compound adapter sleeve and adjusting overcoat 3 inner faces.The screw of adjusting overcoat 3 overlaps the mandrel 4 of overdriving towards interior cover, on cover 1 external screw thread, driving mandrel 4, adjusting overcoat 3, stage clip 2, interior cover 1 is fused in being screwed in.Adjust to regulate the screw-in depth of overcoat 3, can change 2 pairs of pressure that drive mandrel 4 end faces of stage clip, with the clutch protection requirement of the blind that is fit to Different Weight.During operate as normal, under the effect of stage clip 2, the chain wheel that drives mandrel 4 and interior cover 1 is meshing with each other, and moment of torsion transmits by its engages tooth; When the load increase reached to a certain degree, mesh tooth face slided relatively, and chain wheel separates, and realized the overburden protective effect.Specifically be; it is out of control that blinds rises to the top; in the time of can't continuing to promote; winder, power transmission shaft, interior cover all will stop operating; and the axial thrust load of motor torsion is when acting on the pressure that drives mandrel 4 end faces and the frictional force between power transmission shaft and the winder greater than stage clip 2; the chain wheel that drives mandrel 4 and interior cover 1 will separate automatically, thereby protect louvre blade, rope not to be damaged.According to the Different Weight and the overload protection coefficient of blind, can change the pressure of 2 pairs of drivings of stage clip mandrel, 4 end faces to realize the correct clutch of overload protective device by adjusting the position of regulating overcoat 3.
The utility model adopts the compound adapter sleeve of disengaging type and drives mandrel, the damage of having avoided motor, louvre blade, rope to cause owing to runaway electric circuit, prolong the application life of blind product greatly, improved the blind reliability of products, reduced maintenance cost.The utility model is simple in structure, is convenient to assembling, and running is reliable.
