Description

Land flexible gathering formula mosquito net frame and mosquito net

Technical field

The utility model relates to a kind of mosquito net technical field, especially relate to a kind of use that rear mosquito net frame can draw in, take up room little mosquito net frame and mosquito net.

Background technology

Mosquito net is a kind of tent avoiding mosquito bite, usually hangs on bedstead and surrounds bed with isolated mosquito.Mosquito net mostly is netted material, it is windproof that use mosquito net can keep away mosquito, and the dust also descended slowly and lightly in adsorbable air, because mosquito net material is excessively soft, need to be fixed by mosquito net frame, but the quadra that traditional mosquito net frame is generally all made up of four vertical rods and cross bar, although sound construction, but dismounting is inconvenient, not easily reclaim receipts whole, take up room resource, affects attractive in appearance.Therefore, the whole mosquito net of receipts can be reclaimed more in recent years and be loved by the people, as extension support for mosquito net most popular in the market, divide by structure, be divided into the mosquito net frame hung on wall and the mosquito net frame two kinds being with vertical rod.The mosquito net frame hung on wall is structurally made up of bearing, expansion link and cross bar, if China Patent Publication No. is CN202525655U, a kind of practical mosquito net frame, be provided with base, one end of base is provided with the expansion link hinged with base, expansion link is set to 90 degrees by support and base, and the two ends of expansion link are respectively equipped with hook.This supporting structure is simple, can carry out dismounting and shrink, but is greater than the length of lathe bed due to the length requirement under its extended configuration of expansion link, and be suspended in for a long time with it wall, expansion link is easily lower curved on the one hand, and another aspect is also higher to the installation requirement of this in-wall.

Mosquito net frame with vertical rod is by vertical rod, expansion link and cross bar are formed, if China Patent Publication No. is CN203693055U, a kind of full gathering type mosquito net frame, it is characterized in that: described mosquito net frame comprises a pair symmetrically arranged three and connects directional rotating combined mechanism, the a level longitudinally vertical pole of setting and the cross bar of two horizontal cross settings, this connects directional rotating combined mechanism to three and plugs with a cross bar respectively, this vertical pole is arranged on this and connects between directional rotating combined mechanism to three, described three connect directional rotating combined mechanism can drive coupled cross bar to carry out circumference rotation, thus realize the full gathering of mosquito net frame.The mosquito net frame of this structure is installed does not have destructiveness to body of wall, be finished and three connection directional rotating combined mechanisms can be utilized substantially can to realize drawing in completely, but, still there is the flexible problem of expansion link extended configuration span great Rong in this mosquito net, and before gathering, need the support bar of expansion link front end to remove, very inconvenient.

And for example China Patent Publication No. is CN203597684U, a kind of hinged drawn-back type mosquito net frame, comprise vertical a pair montant arranged and horizontally disposed a pair cross bar be connected with described a pair montant, each root cross bar is by a connecting rod and butt bar composition, one end of connecting rod is hinged by adapter with corresponding montant, the other end of connecting rod is hinged with end bar, inner support vertical pole is vertically arranged with between described two adapters, described two butt bars are vertically arranged with split type dismountable outer end and support vertical pole between the termination away from connecting rod, two connecting rods inwardly can intersect gathering by adapter, connecting rod after gathering is pressed close to described the inner and is supported vertical pole, two butt bars also can outwards be opened, connecting rod pressed close to by end bar after opening, thus realize the gathering of mosquito net frame.This mosquito net frame structure is simple, easy to use, and can freely fold, and realizes the full gathering of mosquito net frame.But shortcoming is: 1, this mode of drawing in of intersecting, is easily intertwined in the mosquito net in gathering process on cross bar; 2, because the arcuate part of support front end can not folding, the support after gathering still occupies certain space in the horizontal direction, can not realize drawing in completely.3, the size of mosquito net frame is all fixing, as adult's bed and Children's bed all need to configure according to certain specification, due to this not general shape, user needs the size having a clear understanding of the mosquito net that its needs are bought before choosing, and this is also the problem that some more careless users often ignore.

For this reason, how to provide one to draw in completely, and easy to adjust, take up room little, the mosquito net with good decorative effect has become the problem that people are worth inquiring into.
