Drawings

FIG. 1 is a schematic structural view of the anti-detachment structure at the front end of the motor of the window curtain of the present invention;

fig. 2 is a schematic view of the mounting structure of the rear end cap and the housing of the present invention.

Detailed Description

As shown in fig. 1 and 2, a front-end anti-dismounting structure of a curtain motor comprises a motor body 1, wherein a transfer buckle 3 is arranged between the front end of the motor body 1 and a front end cover 2, one end of the transfer buckle 3 is fixedly connected with the inner side of the front end cover 2, and the other end of the transfer buckle is buckled with the front end of the motor body 1 through a buckle structure; casing 4 is followed the rear end and is gone forward the cover and is docked with front end housing 2 in the motor body 1 outside, is provided with spacing fixture block 5 on the switching knot 3, and front end housing 2 and casing 4 are provided with fore-groove 6 and back groove 7 in the relevant position, and fore-groove 6 and back groove 7 are followed both sides and 5 gomphosis of spacing fixture block, and back end housing 8 is located the rear side of casing 4, supports with the casing 4 rear end, is connected with motor body 1 through chucking spare 9, compresses tightly casing 4 between front end housing 2 and back end housing 8.

Because there is not fixed connection between shell 4 and the front end housing 2, when the motor rotates, it produces relative rotation each other easily, influences the normal use of motor, through embedding spacing fixture block 5 between the front slot 6 of front end housing 2 and the back groove 7 of shell 4, can effectively avoid the relative rotation between shell 4 and the front end housing 2 to and because the connection that the rotation produced is not hard up. Simultaneously, spacing fixture block 5 need prize spacing fixture block 5 by force between front groove 6 and back groove 7 and just can pry it open, nevertheless prize spacing fixture block 5 by force after, the vestige of damage all can appear in spacing fixture block 5, front groove 6 and back groove 7 to can avoid the user to dismantle privately, and then can make things convenient for the accurate quality problems who traces back the product.

The adapter buckle 3 is provided with an axial sliding groove 10, the limiting clamping block 5 is slidably arranged in the sliding groove 10, a reset pressure spring 11 is arranged between the bottom of the limiting clamping block 5 and the bottom of the sliding groove 10, the limiting clamping block 5 comprises a side convex part 12 protruding out of one side of the sliding groove 10 and embedded between the front groove 6 and the rear groove 7, the limiting clamping block further comprises a guide part 13 protruding forwards along the direction of the sliding groove 10, a matched guide hole 14 is formed in the position, corresponding to the guide part 13, of the front end cover 2, and the guide part 13 is inserted into the guide hole 14. When the curtain motor is arranged on the track, the convex guide part can retract inwards by pressing the convex part and compressing the return spring, so that the barrier of the convex guide part on the track is avoided; after the track is installed in place, the guide part can extend out again for limiting under the resilience action of the return spring.

The periphery of the motor body 1 is provided with a raised strip prism 15 which is propped against the shell 4. When the outer shell 4 is sleeved, the strip prism 15 on the periphery of the motor body 1 can support the outer shell 4, so that a certain gap is formed between the motor body 1 and the outer shell 4, the convection of the air inside the motor body is facilitated, and the heat dissipation performance of the curtain motor is improved.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
