Description
Technical field
The utility model relates to electric screw electric machine field, refers more particularly to a kind of electric screw linear push lever apparatus on equipment such as can be applicable to door, window, table, chair, medicine equipment.
Background technology
Traditional opening and closing door and window is by manual push-and-pull, and when door or high-rise window position are higher out of doors, manual operations is difficult for realizing, and cannot realize automation and control.Then with electric pushrod device, realize the electric controling switch of window, use the characteristic of electronic automatic push-pull according to electric pushrod, electric pushrod can be used equally in other place, as: the places such as door, table, chair, medicine equipment, auto parts machinery.The open defects such as but existing electric pushrod device volume is large, noise is large, thrust is little, the scope of application is limited and inconvenient.
Utility model content
The purpose of this utility model is for the problems referred to above, and a kind of electric screw linear push lever apparatus is provided, and volume is little, and thrust is large, and simple in structure, convenient and practical.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of electric screw linear push lever apparatus, it is characterized in that: comprise expansion link, screw rod, fore shell, back cover, motor and reducer, expansion link, fore shell and back cover form three stage structure, described motor and reducer are located in back cover, screw rod is located in fore shell, expansion link one end is located in fore shell and is connected with screw rod, the expansion link other end stretches out in fore shell, screw rod is connected with expansion link by nut, expansion link is provided with the inner chamber that holds screw rod, described nut is fixed on fuselage the inner of expansion link, nut external surface contacts and is provided with plane and can not relatively rotate with fore shell inner surface.
Further, the rearward end of described back cover is provided with tail-hood, can be fastened on corresponding support.
Further, the leading section of described expansion link is provided with termination point casing, can be fastened on corresponding support.
Further, the both ends of described screw rod are provided with needle roller thrust bearing respectively and between back cover and expansion link, reduce friction, make screw rod rotation more steady.
Further, described two needle roller thrust bearing places are respectively equipped with dish-shaped shell fragment, reduce impact force, avoid pushing away motor and cause damage.
Further, between described fore shell and expansion link, be provided with water proof rubber circle, prevent that rainwater or dust from entering electric pushrod inside, shorten the application life of electric pushrod.
The utility model adopts said structure, utilizes motor to transfer electric energy to kinetic energy, uses screw mechanism that rotatablely moving after slowing down by reducer become to stretching motion, and volume is little, and thrust is large, and simple in structure, convenient and practical.
Accompanying drawing explanation
Fig. 1 is that the utility model stretches out state schematic cross-section.
Fig. 2 is the utility model retracted mode schematic cross-section.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail, but not as to restriction of the present utility model.
As shown in Figure 1 to Figure 2, a kind of electric screw linear push lever apparatus, it is characterized in that: comprise expansion link 2, screw rod 5, fore shell 6, back cover 8, motor 9 and reducer 7, expansion link 2, fore shell 6 and back cover 8 form three stage structure, described motor 9 and reducer 7 are located in back cover 8, screw rod 5 is located in fore shell 6, expansion link 2 one end are located in fore shell 6 and are connected with screw rod 5, expansion link 2 other ends stretch out in fore shell 6, screw rod 5 is connected with expansion link 2 by nut 4, expansion link 2 is provided with the inner chamber that holds screw rod 5, described nut 4 is fixed on fuselage the inner of expansion link 2, nut 4 external surfaces contact and are provided with plane and can not relatively rotate with fore shell 6 inner surfaces, the rearward end of described back cover 8 is provided with tail-hood 10, the leading section of described expansion link 2 is provided with termination point casing 1, the both ends of described screw rod 5 respectively and between back cover and expansion link, be provided with needle roller thrust bearing 12, reduce friction, make screw rod rotation more steady, described two needle roller thrust bearing 12 places are respectively equipped with dish-shaped shell fragment 11, reduce impact force, between described fore shell 6 and expansion link 2, be provided with water proof rubber circle 3, prevent that rainwater or dust from entering electric pushrod inside, shorten the application life of electric pushrod.
The rotary power that motor 9 provides acts on screw rod 5 after slowing down by reducer 7, nut 4 because with can not rotate, helicitic texture between screw rod 5 and nut 4 is converted to by rotary power the power that expansion link 2 moves forward and backward, the termination point casing 1 of expansion link 2 ends is fixed on window and just can drives window to do open and close movement, thereby opens the object of electric window-opening and pass window.
More a remote switch device can be set in the wire ends of motor, allow electric pushrod increase the function of Long-distance Control.
The utility model adopts said structure, utilizes motor to transfer electric energy to kinetic energy, uses screw mechanism that rotatablely moving after slowing down by reducer become to stretching motion, and volume is little, and thrust is large, and simple in structure, convenient and practical.
Below the utility model is described in detail, but apparent, those skilled in the art can carry out various changes and improvements, and does not deviate from the scope of the present utility model that appended claims limits.
