Description

A kind of double span wire system mosquito net frame

The utility model relates to a kind of mosquito net frame, especially a kind of mosquito net frame with two backguys.

The double span wire system mosquito net frame of known technology generally comprises support post, the framework of the left and right sides and front and back cross bar are formed, the framework of the left and right sides has rail plate or peg, motion bar is arranged between the two, as the patent No. is ZL98234397.3, notification number is CN2331232Y, name is called the patent of the full retractable mosquito net frame of a kind of double span wire system, a pulley is respectively adorned in the both sides, front and back end of its mosquito net frame, and a horizontal trolley and the perpendicular pulley of putting be housed respectively below latter two pulley, walk around each pulley by a rope, and two ends and homodromous two sections backguys of motion bar are linked.Adopting the advantage of said structure is that the mosquito net folding is more convenient.But stay cord twines complicated, and stay cord is fragile, and inconvenience is installed, and simultaneously because firmly uneven with pulling rope, easily make the motion bar inclination or blocks.

The purpose of this utility model be to provide a kind of easy to install and use, stay cord is not fragile, the mosquito net folding operates steadily, double span wire system mosquito net frame simple in structure.

For achieving the above object, the utility model is to adopt following scheme to realize: the double span wire system mosquito net frame comprises two support posts, the framework of the left and right sides and front and back cross bar are formed, the framework of the left and right sides is rail plate or peg is arranged, be connected to motion bar between the two, front rail is equipped with two fixed pulleys or link along symmetric position inboard, center, an axle that can rotate flexibly is equipped with near the rear transverse rod position in rear portion at support, the rotation shaft unit that axle is rotated is housed on this, also be fixed with two pairs of reels on the axle or on axle, have two pairs of cannelures, the two pairs of reels or groove are corresponding with two fixed pulleys or link position on the front rail, article two, a termination of rope is separately fixed on each reel or groove of two centerings, the correspondence position that passes corresponding fixed pulley on the front rail or link and motion bar behind the line of last q.s again links, other has the termination of two ropes to be separately fixed in addition on two reels or the groove, links with the opposite position of motion bar behind the line of last q.s in the other direction.

The rotation shaft unit that axle is rotated can adopt on axle the adjacent position to fix a pair of reel again or have a pair of cannelure, article one, a termination of rope is fixed on a reel or the groove, behind the line of last q.s and sagging one section more in the other direction around the line of last q.s on another reel or groove, and the termination is fixed thereon; Also can adopt and on axle, fix a gear-like driving wheel, on driving wheel, put by a string beading constitute and sagging stay cord constitute; Can also adopt the motor transmission and load onto the rotation that remote control drives axle; Rotation shaft unit can be contained in a last arbitrary position, also can respectively load onto a cover at the axle two ends, and making all can the folding mosquito net on the both sides of bed.

Axle can adopt to insert in two ball bearing endoporus that are fixed on the support and be connected with support, also can be to insert to be fixed in the circular hole of support the right and left.

After adopting said structure,, make motion bar stressed more even relatively because the power of stay cord is transmitted by axle, move steady relatively, also not fragile rope; Rotation shaft unit can be contained in arbitrary position of axle, perhaps all is equipped with in both sides, even the rotation shaft unit of the motor transmission of band remote control is housed, thereby use more convenient.

Be described further below in conjunction with drawings and Examples.

Fig. 1 is the utility model overall structure schematic diagram;

Fig. 2 is the utility model stay cord coiling schematic diagram.

As Fig. 1, double span wire system mosquito net frame of the present utility model shown in Figure 2 comprises two support posts 1, the framework 2 of the left and right sides, 3 and front and back cross bar 4,5 form, the framework 2 of the left and right sides, 3 also is rail plate simultaneously, be connected to motion bar 6 between the two, front rail 4 is equipped with two fixed pulleys or link 7 along center line symmetry inboard, near rear transverse rod 5 positions one turning cylinder 8 flexibly is housed at the rear portion of support, the rotation shaft unit 9 that axle 8 is rotated is equipped with in these 8 both sides, rotation shaft unit 9 is two fixing reel 9-1 of adjacent position on axle, 9-2, article one, a termination of rope is fixed on the reel 9-1, behind the line of last q.s and sagging one section more in the other direction around the line of last q.s on another reel 9-2, and the termination is fixed thereon; Also be fixed with two pairs of reels 10,11 on the axle, two pairs of reels 10,11 are corresponding with the fixed pulley position on the front rail 4, respectively there is a termination of a rope to be fixed on in two pairs of reels 10,11 one, link around the relevant position of passing fixed pulley 7 and motion bar 6 on the front rail 4 behind the line of last q.s again, respectively there is the termination of another rope to be fixed on another reel in two pairs of reels 10,11, behind the line of last q.s, links in the other direction with the opposite position of motion bar 6.Respectively be fixed with a ball bearing 12 in the both sides of support, axle 8 inserts in ball bearing 12 endoporus and is connected with support, easily links in order to make rope and motion bar 6, and hook or little ring etc. can be loaded onto in the corresponding position of motion bar 6.

In a last embodiment, the rotation shaft unit 9 that axle is rotated also can adopt fixes a gear-like driving wheel on axle, puts by a string beading to constitute and sagging stay cord constitutes on driving wheel; Thereby can also adopt the gear on the driven by motor axle to rotate the rotation that drives axle, motor switch also can be loaded onto remote control; Rotation shaft unit 9 also can be contained in a last arbitrary position; Above-mentioned reel comprises that the reel among the embodiment all can be replaced by the cannelure of being opened on axle; So simultaneously, ball bearing 12 also can adopt and be fixed on support the right and left, interior round-meshed wheel or other object and substitute, as long as can retainer shaft 8 can rotate flexibly within it, have groove the axle or the axle and reel can also be fixed on the rear transverse rod, above-mentioned all these changes can constitute the different embodiment of the utility model.
