Description

Mosquito net frame

Technical field

The utility model relates to articles for use, particularly a kind of mosquito net frame at home.

Background technology

Mosquito net, every tent outside, refers in particular to mosquito to hang over a kind of tent on bedstead, bed being surrounded.Belong to small stores, summer, south was essential.Mosquito net is of a great variety, by account top shape, is divided into dome and rectangular top mosquito net.Tradition mosquito net is rectangular top, its after hanging, have inner space large, be by comfortable feature.The hanging method of tradition mosquito net is to wear account bar in the both sides account cylinder on account top, account bar by stent support be suspended on ceiling or room beam on.It not only gets or hangs complex operation, therefore, conventionally when changing according to the season, just hangs up or collects.It not only affects indoor attractive in appearance, and takies daily living space.For this reason, at present, there is the mosquito net frame of convenient folding.But there is complex structure, scope of application limitation, the halfway deficiency of folding in existing mosquito net capable of being folded support.For this reason, need to improve.

Summary of the invention

The purpose of this utility model is exactly for the deficiencies in the prior art, provide a kind of simple in structure, applied widely, folding is thorough, and the mosquito net frame of good stability.

For achieving the above object, the utility model adopts following technical scheme:

A kind of mosquito net frame, comprise the column of the two rectangular tube structures that are oppositely arranged, telescopic account bar, column lower end is provided with sole, between two columns, be provided with tensioned lines and crossbeam, telescopic account bar comprises the fundamental segment of tubular style structure, in the socket of fundamental segment, be provided with the telescopic joint that can be stretched out by its far-end, two telescopic joints form removable being fixedly connected with; Fundamental segment upside far-end is fixedly connected with a drag-line; Described column top is slidably socketed one first sliding sleeve, and two first sliding sleeves are fixedly connected with by described crossbeam, and the fundamental segment near-end of described telescopic account bar and described the first sliding sleeve are hinged; Between the first sliding sleeve and fundamental segment, a use is set so that the extreme position that fundamental segment is toppled over is the position-limit mechanism that axis is the level of state; The other end of described drag-line is fixedly connected on the first sliding sleeve, and described column top is provided with one for supporting the pulley of described drag-line, and the first sliding sleeve is when limit inferior position, and account rod axis is vertical state; Described column bottom sliding sleeve one comprises the second sliding sleeve of gripper shoe, and two gripper shoes on two second sliding sleeves are setting in opposite directions, be also provided with for the second sliding sleeve and described column and form fixing lock-screw on the second sliding sleeve; Described tensioned lines is fixedly connected with by two second sliding sleeves or two gripper shoes.

The utility model that adopts aforementioned techniques scheme, because column is made by rectangle pipe material, in the material consumption situation of identical weight, can improve the sectional dimension of pillar construction, is convenient to increase the stability of mosquito net frame; Column lower end is provided with sole, can make column and mosquito net frame fixation by add the mode of loads on sole, and it is easy to operate; Also can use swell fixture mode and ground to form by sole fixing, can guarantee fixation, use safety.Slide over and slip in journey when first, fundamental segment rotates by pin joint, its far-end dips down and moves, under Action of Gravity Field, fundamental segment makes drag-line all the time in tensioning state, and the first sliding sleeve provides a lifting force making progress to overcome its gravity, now by drag-line, if telescopic joint is pulled out, its tensioning and castering action are more reliable.When fundamental segment, telescopic joint approach or are horizontal, fundamental segment and telescopic joint form cantilever beam, the horizontal component of drag-line acts on the first sliding sleeve by fundamental segment horizontal direction, make the first sliding sleeve be close to column, thereby increase the coefficient of friction between the two, increase static friction force, the first sliding sleeve overcomes Action of Gravity Field by drag-line lifting force and static friction force and keeps static.When hanging with after mosquito net on account bar, its stability is better; In addition, the first sliding sleeve is when limit inferior position, and account rod axis is vertical state.Guarantee to take up room after its folding little, folding is thorough.

The utility model arranges by comprising that at column bottom sliding sleeve one the second sliding sleeve of gripper shoe, two gripper shoes on two second sliding sleeves are in opposite directions, is also provided with for the second sliding sleeve and described column and forms fixing lock-screw on the second sliding sleeve.Utilize the gripper shoe of the second sliding sleeve setting for being supported on plane on edge of bed, thereby form firmly, support, the edge of bed that no matter used is high or low, all can use easily, and it is applied widely.Between two second sliding sleeves, be provided with tensioned lines, further to increase support steadiness, tensioned lines is fixedly connected with by two second sliding sleeves or two gripper shoes simultaneously.When second slides over gripper shoe below and also has the extended structure of U-shaped frame, can make column lower sides be close to a sidewall, by the second sliding sleeve, further improve the stability of mosquito net frame.

The utility model is also by a position-limit mechanism is set between the first sliding sleeve and fundamental segment, with so that the extreme position that fundamental segment is toppled over is axis is the level of state, further to guarantee the stability of support.

The utility model beneficial effect is compared with prior art, simple in structure, applied widely, folding is thorough, and good stability, uses safety.
