The safe on-off device comprises an input shaft and an output shaft which are mounted on the housing, wherein an end face bearing for fixing the input shaft is arranged at one end of the housing, and wherein an input rotating disc and an output rotating disc are fixed at the connected ends of the input shaft and the output shaft, respectively; a group of through holes distributed at intervals are formed on the output rotating disc and steel balls are arranged in the through holes; grooves corresponding to the positions of the through holes are formed on the input rotating disc; a steel ball pressing plate for pressing the steel balls in the grooves is sleeved to the output shaft; an elastic element propping against the steel ball pressing plate is arranged at the outer end of the steel ball pressing plate; and a gland for limiting the elastic element is fixed at the outer end of the housing, and the output shaft penetrates through the gland. The safe on-off device on the door closer is characterized in that when the door is opened and closed by violating the normal automatic mode, and in order to prevent vicious or accidental artificial damage, the steel balls push the steel ball pressing plate and the butterfly spring under instantaneous stress so that the steel balls come out of the grooves on the input rotating disc and rotate to next grooves, and as a result, a clutch is caused to have an angular displacement to achieve the effect of protecting the motor and the output shaft.
Description
Technical field
The utility model relates to a kind of door closer, and is especially a kind of for the safe engaging and disengaging gear on the door closer.
Background technique
At present, door closer in use, door closer particularly, the motor driving input shaft on the door closer rotates, and input shaft drives output shaft and rotates, and the unavoidable situation of switch door when normal automatic mode takes place to violate, or some malice or unexpected artificial the damage are taken place, and make output shaft block suddenly, understand driving mechanism and the drive motor of major injury door closer like this, afterwards influence the door closer operation easily repeatedly impaired, even cause door closer to damage.
The model utility content
The utility model will solve the shortcoming of above-mentioned prior art, and the safe engaging and disengaging gear on a kind of door closer is provided, and door closer is played a very good protection.
The utility model solves the technological scheme that its technical problem adopts: the safe engaging and disengaging gear on this door closer, comprise the input shaft and the output shaft that are installed on the housing, one end of housing is provided with the fixedly end face bearing of input shaft, wherein the connecting end of input shaft and output shaft fixedly has input rotating disk and output rotating disk respectively, the output rotating disk is provided with one group of through hole spaced apart, be provided with steel ball in the through hole, the input rotating disk is provided with the groove corresponding with lead to the hole site, and be with at output shaft steel ball is pressed in steel ball pressing plate in the groove, the outer end of steel ball pressing plate is provided with roof pressure at the elastic component of steel ball pressing plate, and the gland of spacing elastic component is fixedly arranged in the housing outer end, wherein output shaft passes gland.Under normal situation about using, the steel ball pressing plate in groove, interconnects input rotating disk and output rotating disk the steel ball roof pressure, therefore input shaft and output shaft is in transmission connection like this; Under something unexpected happened; when input shaft is difficult to rotary output axis; the rotatory force of input shaft is excessive, and therefore the groove of importing on the rotating disk plays an axial thrust to steel ball, makes in the outside movement of steel ball and the disengaging groove; make input rotating disk and output rotating disk be in separated state; each parts in the door closer are played a very good protection, behind the input dial rotation several angle, be subjected to the elastic force effect of elastic component; steel ball is got back in the next groove again, is in drive state again.So just can avoid causing because active force is excessive the situation of damage of components to take place.
For further perfect, wherein the interior edge face of gland is provided with elastic pressuring plate, and has screw at gland, is provided with the screw of roof pressure elastic pressuring plate in the screw.Can lock the position of gland like this, the stroke of elastic component is played fixation.Gland is threaded on the housing.The inside and outside movement that gland can be suitable like this, can regulate the elasticity of elastic component, the degree of tightness of elastic component is extremely important to the safe clutch between input shaft and the output shaft, if elastic component is too tight to the roof pressure of steel ball pressing plate, then cause safety coefficient to reduce, and elastic component is too loose to the roof pressure of steel ball pressing plate, then can cause the transmission between input shaft and the output shaft loosening, the transmission instability.
Its further groove is the conical socket structure that is complementary with the steel ball size.Such structure is conducive to safe clutch between input shaft and the output shaft.Wherein elastic component is dish spring or helical spring.Elastic component is preferentially selected the dish spring for use, is enclosed within on the output shaft by one group of elasticity video disc, according to the different model door closer, the length difference of its required elastic component, select for use butterfly elasticity to be convenient to regulate its required length, and helical spring use is very extensive, the cost cost is low.
The effect that the utility model is useful is: under the situation of the utility model switch door when violating normal automatic mode; for preventing malice or unexpected artificial the damage; promote steel ball pressing plate and adjusting spring when steel ball is stressed in moment; thereby break away from the groove of steel ball on the input rotating disk; rotation causes clutch to produce the effect that angle displacement is realized protection motor and output shaft to next groove.The reduction gear of protection motor internal and each accessory on the output shaft, each link gap of having avoided slight damage to cause becomes big phenomenon.The application of safety clutch on this door closer significantly reduced and safeguarded probability and cost, and dynamics is regulated the elasticity of elastic component by gland according to the weight of door.
