The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, a kind of collapsible mosquito net frame comprises support body and holder 1; Support body is connected with holder 1; Said support body comprises two driving levers 21, two follower levers 22 and a class " U " shape end bar 23, and driving lever 21 articulates with follower lever 22, and follower lever 22 connects 23 with type " U " shape end bar pivot;

Also comprise transverse axis 3, first worm gear 4, second worm gear 5, second worm screw 6, drain pan 7, protecgulum 8 and the drive unit of a two ends band worm screw, the hand of spiral of the worm screw at transverse axis 3 two ends is opposite;

The front end of said holder 1 has two to articulate frame 1A, and the holder between the two pivot joint frame 1A has through hole 1B, and there is pivoted hole 1C the holder both sides;

Transverse axis 3 articulates with the pivoted hole 1C of holder 1, and rotating shaft articulates with articulating frame 1A, and rotating shaft is fixedly connected with first worm gear 4, and driving lever 21 is fixedly connected with rotating shaft; Worm gear 4 passes through hole 1B and cooperates with worm screw on the transverse axis 3;

Second worm screw 6 and second worm gear 5 articulate with drain pan 7 and protecgulum 8 respectively, and second worm gear 5 is fixedly connected with transverse axis 3; Drain pan 7 removably connects with holder 1, and protecgulum 8 is screwed with drain pan 7 and is connected; Drive unit is fixed on drain pan 7 and the protecgulum 8, and drive unit is connected transmission with second worm screw 6.

Like Fig. 3, Fig. 4, shown in Figure 5, drive unit 9 comprises band guide holder internal tooth and pilot hole 91, actuator 92, planetary gear 93, sprocket wheel 94, is arranged on output gear 95 and jack 96 on the sprocket shaft;
