Abstract
The utility model relates to an over torque type electric pushing pole which is used in the electromotive implementing mechanism to realize the automatic control, pertaining to a to and fro moving electric driving device, mainly consisting of a screw pole, a pushing pole, a canal, a shell body and a motor. The utility model is characterized in that one end of the screw pole is provided with a gear connecting cover, a steel ball fixing rack, a steel ball, a convex shaped spring, a big gear, a middle gear and a small gear. The utility model has the advantages of simple, compact and rational structure, low manufacturing cost, small volume and quality, reliable and stable capability and not easy to burn the motor; as one end of the screw pole is provided with a gear connecting cover, gears, a steel ball and a convex shaped spring to make the over torque skid through the clutching action so as to make the pushing pole have overload to protect the motor in the operating process, preventing overloading effect and applicable for the electromotive implementing mechanisms of every walk of life to realize automatic control.
Description
Technical field:
The utility model relates to a kind of moment of torsion formula electric pushrod of crossing, and is used for electric operator to realize automatic control, belongs to a kind of reciprocating power-jdriven gear.
Background technology:
Before the utility model was made, in prior art, the electric pushrod that is used for electric operator mainly was made up of screw mandrel, push rod, conduit, housing and overload protection arrangement.Its overload protection arrangement adopts helical spring to be pressed on the screw mandrel.The helical compression spring pressurized that the electric pushrod of this kind structure is to use promotes the travel switch power-off protection by driving lever, thereby reaches the overload protection motor.Its weak point is that volume is big, the electric appliance circuits complexity; Easy burn-out motor when travel switch breaks down.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple, compact and reasonable for structure; Volume is little, and quality is little, flexibility and reliability; Can effectively protect motor, prevent the moment of torsion formula of the crossing electric pushrod of overload effect.
Main solution of the present utility model is achieved in that
It mainly adopts screw mandrel 5 to be installed in the housing 2, copper nut 4 is installed on the screw mandrel 5, push rod 8 is enclosed within on the copper nut 4, conduit 9 is installed on the housing 2, it is characterized in that bearing 10 is fixed on the screw mandrel 5, gear adapter sleeve 11 is installed on the screw mandrel 11, steel ball fixed mount 3 is installed on the screw mandrel 5, steel ball 12 is contained on the steel ball fixed mount 3, and steel ball 12 is pushed down by convex spring 14, and gear wheel 13 is contained on the screw mandrel 5, gear wheel 13 and central gear 15 engagements, and drive pinion 16, and pinion 16 is installed on 1 in the motor, and motor is installed on the housing 2.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Low cost of manufacture, easy to install and use; Volume is little, quality is little, and dependable performance is stable; Easy burn-out motor not; Because gear adapter sleeve, gear, steel ball and convex spring are housed on screw mandrel one end; and cross moment of torsion with screw mandrel by clutch action and produce and to skid; thereby make push rod the overload protection motor in running, occur; can prevent the effect of surmounting; and can be widely used in the electric operator of all trades and professions, to realize automatic control.
Description of drawings:
Fig. 1 is the utility model structural representation;
Embodiment:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model screw mandrel 5 is installed in and adopts nut 17 fastening in the housing 2.End at screw mandrel 5 is installed bearing 10, and gear adapter sleeve 11 is installed on the screw mandrel 5, and steel ball fixed mount 3 is installed on the screw mandrel 5, and steel ball 12 is installed on the steel ball fixed mount 3, and convex spring 14 is pushed down steel ball 12.Gear wheel 13 is installed on the screw mandrel 5, and gear wheel 13 engagement central gears 15, central gear 15 and pinion 16 engagements, pinion 16 are installed on 1 in the motor, and motor 1 is installed on the housing 2.Screw mandrel 5 tightens copper nut 4, and push rod 8 is enclosed within on the copper nut 4, and sealing ring 7 is installed on the push rod 8, and is stuck on the conduit 9, and conduit 9 is contained on the housing 2, connects connector 6 on the push rod 8.
The utility model is to utilize gear, gear adapter sleeve, steel ball and spring on the screw mandrel and screw mandrel to cross moment of torsion by clutch action to produce and skid, thereby makes push rod the overload protection motor occur in running; And push down a plurality of steel balls by the convex spring on the screw mandrel and produce moment of frictions and be bonded together.These two moment sums make gear and screw mandrel rotate synchronously just when operate as normal, thereby make push rod run to two ends when overload gear to skid with the screw mandrel generation, thereby play the protection motor, prevent the overload effect.
