Novel screen window
Technical field
The utility model relates to the screen window technical field, particularly relates to a kind of novel screen window.
Background technology
As everyone knows, screen window is a kind of being arranged on the window, is used for furniture building materials mosquito-proof and the energy available ventilation, is widely used in the furniture building materials field; Existing screen window, usually be divided into collapsible screen window and can not fold screen window, wherein, collapsible screen window generally includes yarn box, gauze, pull bar, frame and underframe, the yarn box is arranged on the top of window, underframe is arranged on the bottom of window, and the top of gauze is fixed in the yarn box, but and elasticity be involved in the yarn box, the bottom of gauze is connected with pull bar, pull bar drags gauze and is fixed on the underframe, slides in frame relatively in the two ends of pull bar, and the width of gauze and height are complementary with window; Collapsible screen window so in use, utility model people finds that exist pull bar not stablize is fixed on effectively on the underframe, causes mosquito-proof effect relatively poor, or pull bar connector complex structure, the cost of production problem of higher.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of and can effectively pull bar be fixed on the underframe, and is simple in structure, the novel screen window that cost of production is lower.
Novel screen window of the present utility model, comprise the yarn box, gauze, pull bar, frame and underframe, the cross section of described underframe is U-shaped, described underframe comprises anter, substrate and rear panel, described anter and rear panel are separately fixed at the both sides, front and back of described substrate, the top of described rear panel is provided with the sheet that colludes to the bending of described anter direction, the described angle that colludes sheet and described rear panel is spent less than 90 greater than 0 degree, the inboard of described rear panel also is provided with blend stop, described blend stop is arranged on described below of colluding sheet, described pull bar is sheet, the top of described pull bar is provided with the gauze connector, described gauze connector is fixedlyed connected with the bottom of described gauze, and the bottom of described pull bar is provided with described and colludes the hook that sheet matches.
Further, also be provided with protuberance on the described pull bar, the cross section of described protuberance is arc, and described protuberance and described hook are positioned at the both sides, front and back of described pull bar.
Further, the bottom of described pull bar also is provided with catch, and described catch is arranged on the top of described hook, and is arranged on the homonymy of described pull bar with described hook.
Further, describedly collude distance between end, sheet bottom and the described rear panel less than the distance of the relative described rear panel in described blend stop end.
Further, also be connected with support chip between described anter and the rear panel, described support chip is positioned at described below of colluding sheet, and the width of described support chip is consistent with the width of substrate.
Compared with prior art the beneficial effects of the utility model are: the cross section of underframe is U-shaped, underframe comprises anter, substrate and rear panel, anter and rear panel are separately fixed at the both sides, front and back of substrate, the top of rear panel is provided with the sheet that colludes to the bending of anter direction, colluding the angle of sheet and rear panel spends less than 90 greater than 0 degree, the inboard of rear panel also is provided with blend stop, blend stop is arranged on the below of colluding sheet, pull bar is sheet, the top of pull bar is provided with the gauze connector, the gauze connector is fixedlyed connected with the bottom of gauze, and the bottom of pull bar is provided with and colludes the hook that sheet matches; Slide in frame relatively in the two ends of pull bar, and on the pull bar slip plane of hook at anter with collude between the sheet, under the situation that does not add external force, pull bar moves down and can't cause hook and collude linking of sheet; But in use, the user presses pull bar and moves down, and contacts with colluding sheet up to hook, and snaps in and collude in the sheet, finishes interconnecting of pull bar and underframe, and this connected mode is simple and stable; When needs are regained pull bar, press pull bar and continue to move downward, by blend stop jack-up, at this moment, the user only need loose one's grip up to hook, and gauze just can be with pull bar upwards to rebound automatically, and simple in structure, cost of production is lower, and easy to use.
Description of drawings
Fig. 1 be the utility model cut open to structural representation.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, novel screen window of the present utility model, comprise the yarn box, gauze, pull bar 1, frame and underframe 2, the cross section of underframe 2 is U-shaped, underframe comprises anter, substrate and rear panel, anter and rear panel are separately fixed at the both sides, front and back of substrate, the top of rear panel is provided with colludes sheet 21 to the bending of anter direction, collude sheet 21 and spend less than 90 greater than 0 degree with the angle of rear panel, the inboard of rear panel also is provided with blend stop 22, and blend stop 22 is arranged on the below of colluding sheet 21, pull bar 1 is sheet, the top of pull bar 1 is provided with gauze connector 13, and gauze connector 13 is fixedlyed connected with the bottom of gauze, and the bottom of pull bar 1 is provided with and colludes the hook 11 that sheet matches; Slide in frame relatively in the two ends of pull bar, and on the pull bar slip plane of hook at anter with collude between the sheet, under the situation that does not add external force, pull bar moves down and can't cause hook and collude linking of sheet; But in use, the user presses pull bar and moves down, and contacts with colluding sheet up to hook, and snaps in and collude in the sheet, finishes interconnecting of pull bar and underframe, and this connected mode is simple and stable; When needs are regained pull bar, press pull bar and continue to move downward, by blend stop jack-up, at this moment, the user only need loose one's grip up to hook, and gauze just can be with pull bar upwards to rebound automatically, and simple in structure, cost of production is lower, and easy to use.
Also be provided with protuberance 12 on the pull bar, the cross section of protuberance 12 is arc, and protuberance and hook are positioned at the both sides, front and back of pull bar; Like this, can make things convenient for the user to the pressing operation of pull bar.
The bottom of pull bar also is provided with catch 14, and catch 14 is arranged on the top of hook, and is arranged on the homonymy of pull bar with hook; Like this, can prevent effectively that pull bar from excessively moving down.
Collude distance between end, sheet 21 bottom and the rear panel less than the distance of the relative rear panel in blend stop 22 ends; Like this, in the time of pull bar need being regained, pressing pull bar continues to move downward, up to hook by blend stop jack-up, at this moment, the user only need loose one's grip, and gauze just can be with pull bar upwards to rebound automatically, and collude distance between end, sheet bottom and the rear panel less than the distance of the relative rear panel in blend stop end, be conducive to the retraction of gauze.
Also be connected with support chip 23 between anter and the rear panel, support chip 23 is positioned at the below of colluding sheet, and the width of support chip is consistent with the width of substrate; Improved the stability of underframe like this, effectively.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
