Description

But a kind of account encloses the mosquito net of vertical lift

The utility model relates to improved mosquito net, but particularly a kind of account encloses the mosquito net of vertical lift.

As everyone knows, mosquito net is a kind of both ventilation and penetrating lights, and bedding that can be mosquito-proof are used very extensive again.Especially in the place of some many mosquitos, then essential.Yet mosquito net hangs from above when not using and has just occupied many space of bedroom in bed, makes the bedroom seem narrow, if receipts are whole bad just in disorder, is unfavorable for beautifying and daylighting of bedroom.Various luxury imperial court formula mosquito nets are arranged, but deficiency is that it receives opening apparatus still based on landscape mode, does not also thoroughly deal with problems in prior art.Though also the someone proposed the design of Liftable mosquito net, owing to account enclose descending operation easily and account enclose and can not hang into orderly shape from above and be difficult to apply.

The purpose of this utility model is to provide that a kind of structure is comparatively simple, account encloses lifting freely, but space of bedroom influence account few and good decorating effect is enclosed the mosquito net of vertical lift.

Task of the present utility model realizes by this way: this mosquito net includes the account top frame, the mosquito net lowering or hoisting gear, pulley, the folding and unfolding rope, pull rope, lock, mosquito net and little ring, it is characterized in that the mosquito net lowering or hoisting gear is by driving wheel, driving gear, two twisted rope wheels, two driven gears, driving shaft and two driven shafts and bearing bracket stand are formed, driving wheel and driving gear are loaded on the driving shaft, two twisted rope wheels dispose mutually with two driven gears and are loaded on two driven shafts, driving gear meshes with two driven gears respectively, driving shaft and two driven shafts are located with fixing with the upper plate and the lower plate of bearing bracket stand, whole mosquito net lowering or hoisting gear is connected the centre that places the account top frame by a fixing with it crosspiece with the account top frame, the folding and unfolding rope that each bar passes the pulley on little ring of mosquito net and the account top frame half-and-half separately links with two hinge rope sheaves respectively, one end of pull rope and driving wheel link and in going into race an end length, the other end hangs from above below lock after passing lock.

The utility model is like this work: enclosing at the mosquito net account needs to rise after sagging when folding, can spur the pull rope that hangs from above below lock rotates driving wheel, transmission by driving gear and driven gear drives the rotation of twisted rope wheel, with each bar folding and unfolding rope slowly in the race of going into two twisted ropes wheel, making the mosquito net account enclose the lower end constantly up promotes, enclose up to whole account and to be received till the top, account enclosed and can not descend because the locked device of pull rope pins this moment.If mosquito net will be fallen, as long as lock is unclamped, releasing is to the constraint of driving wheel, mosquito net is slowly sagging under the deadweight effect, and drive folding and unfolding rope moves downward, drive the counter-rotating of twisted rope wheel, the engagement by driven gear and driving gear drives the driving gear rotation conversely again, make driving wheel again with pull rope in going into its race and reset.

Compared with the prior art the utility model has following advantage:

1, pull rope of the present utility model and folding and unfolding rope all rely on the driving wheel of rolling, and hinge rope sheave and pulley move, and frictional force is little, and motion makes the descending operation of mosquito net very light freely.

2, owing to adopt the minor diameter driving wheel, major diameter driving gear and minor diameter driven gear and major diameter twisted rope wheel, therefore the pull rope a bit of distance of moving, the folding and unfolding rope big segment distance that just moves, improve account effectively and place lifting speed, make and finish account and enclose to promote and only need a bit of pull rope of pulling just can realize, the convenient use.

3, because the utility model can enclose account even rising and receive to the account top frame, can not occupy too many space, keep the bedroom spacious clean and tidy.In addition, as long as the account enclosing that will add outside the account top frame after an escutcheon will fold is lived, it is neat and artistic just to seem.

4, each bar folding and unfolding rope of the present utility model separately cuts with scissors the weak point that knot influences each autokinesis together around only overcoming double easily on a hinge rope sheave to two twisted ropes wheels.

5, simple in structure, easy enforcement.

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

Fig. 1 is the utility model stereoscopic-state schematic diagram.

Fig. 2 is the vertical view cutaway drawing of mosquito net lowering or hoisting gear (3) among Fig. 1.

Fig. 3 is along the cutaway view of A-A line among Fig. 2.

As shown in Figure 1, account top frame 1 usefulness steel tube bending forms, and around it 6～12 pulleys 4 is set evenly, and the top of mosquito net 8 links on account top frame 1.Mosquito net lowering or hoisting gear 3 is fixed in the centre that places account top frame 1 on the strut rail 2.Mosquito net lowering or hoisting gear 3 of the present utility model as shown in Figure 2, its driving wheel 13 is contained on the driving shaft 15 with driving gear 12,11 and two driven gear 14 mutual configurations of two twisted rope wheels are loaded on respectively on two driven shafts 16, driving shaft 15 and two driven shafts 16 are the isosceles triangle distribution and are fixed on the upper and lower plate of bearing bracket stand 10, and allow driving gear 12 and two driven gears 14 mesh.One end of each folding and unfolding rope 6 lies in mosquito net 8 accounts and encloses the lower end, and the other end passes ties the little ring 9 that becomes to arrange shape on mosquito net 8, passes pulley 4 again and lies at last on the twisted rope axle 11, and two twisted rope wheels 11 respectively are the folding and unfolding rope 6 that half is arranged.One end of pull rope 5 lies on the driving wheel 13 and around going into its race one segment distance, and the other end passes the below that places lock 7 on the account top frame 1 to hang on lock 7.Do not expose for account after folding is enclosed, can enclose 17 at decoration of account top frame 1 arranged outside.
