Detailed Description

The following describes in further detail embodiments of the present invention with reference to the accompanying drawings. The following embodiments are provided to illustrate the present invention, but are not intended to limit the scope of the present invention.

As shown in fig. 1, the three-way structure for fixing the mosquito net frame comprises a cross bar 1, a three-way 2 and a sleeve 8. The horizontal pole connecting portion 4 of tee bend 2 cup joints at horizontal pole 1 right-hand member through shrink face 5, cup joints sleeve pipe 8 on the shrink face 5, with horizontal pole connecting portion 4 locking on horizontal pole 1. The upright post connecting part 12 of the tee joint 2 is sleeved on the upright post of the bracket. Through sleeve pipe locking shrink face, no matter how big change the horizontal pole pipe has, the shrink face homoenergetic matches with the pipe that has the diameter error, realizes the effective locking of tee bend and horizontal pole.

As shown in fig. 2, a groove 3 is arranged on the cross rod 1; the groove 3 is matched with the convex ring 7 to realize clamping.

As shown in fig. 3, the cross bar connecting part 4 of the tee joint 2 is provided with a contracting surface 5, and the contracting surface 5 is inclined from the cross bar connecting part 4 to the end part. The end part of the contraction surface 5 is provided with a clamping groove bulge 6. The clamping groove bulge 6 is matched with the locking notch rib II 10, and the convex ring 7 is clamped in the groove 3. The inner side surface of the clamping groove bulge 6 is provided with a convex ring 7. The number of the contraction surfaces 5 is at least two, and in the present embodiment, two. Openings 13 are formed adjacent to each other. The cross section of opening 13 is isosceles trapezoid, and the opening size of horizontal pole connecting portion 4 department is big, and the opening size of left side tip is little. All set up reinforcing plate 14 between horizontal pole connecting portion 4, horizontal pole connecting portion 4 and the stand connecting portion 12, increase tee bend 2's intensity.

As shown in fig. 4, a locking rib i 9 and a locking rib ii 10 are sequentially arranged in the sleeve 8. The joint of the two lock catch ribs is provided with a slope, so that the protrusion 6 of the clamping groove can pass through conveniently. The fore shaft rib I9 is located at one end close to the tee joint 2, and the inner wall of the fore shaft rib is attached to the outer wall of the cross rod connecting portion 4. The right side port of the locking rib I9 inclines from inside to outside. The left end of the sleeve 8 far away from the tee joint 2 is provided with a bead 11. The internal diameter of the locking rib I9 is larger than that of the locking rib II 10. The outer surface of the sleeve 8 is provided with grains, so that friction is increased, and assembly and disassembly operations are facilitated.

The working process is as follows: the sleeve pipe 8 is worn to establish on horizontal pole 1, and tee bend 2's horizontal pole connecting portion 4 cup joints at 1 tip of horizontal pole through shrink face 5, and recess 3 is gone into to the 7 cards of bulge loop, pushes sleeve pipe 8 to tee bend 2, makes the protruding 6 lateral surfaces of draw-in groove paste tightly with II 10 inner walls of fore shaft muscle, and bead 11 supports tight draw-in groove protruding 6 ports, and the laminating of I9 inner walls of fore shaft muscle and 4 outer walls of horizontal pole connecting portion this moment, and tee bend 2 locking can not drop on horizontal pole 1.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
