Abstract

The utility model relates to a rolling mesh window which is composed of a window screen, a pressing bobbin and a yarn pressing rod for grasping the window screen, a left guide way and a right guide way, left and right supporters for supporting a coil bobbin, a weight dropper, a rope pulley with the same axle with the coil bobbin, a rope and a weight dropper guide way. The utility model is characterized in that the weight of the weight dropper equals the sum of the weight of the pressing bobbin and the weight of the yarn pressing rod. The weight dropper is provided with a spring tensioning mechanism so that the window screen can be automatically tensioned when the screen window is closed. The utility model has no impact when opened and closed and has the advantages of convenient operation and simple manufacture, suitable for being used in the household place and the office.

Description

Rolling mesh window

The utility model relates to a kind of room window technology field, especially rolling screen window.

At present, the screen window that esidential building uses mainly is a flat opening, and it is big to take up space during unlatching, uses inconvenient, in recent years, rolling screen window emerges successively, takes up space greatly inconvenient problem with use though solved, but, because no balance sysmte, during unlatching impact bigger, influenced the result of use of screen window.

The purpose of this utility model designs a kind of novel rolling screen window exactly, and this screen window switch is steady, and window screening is tightened automatically.

Technical solution of the present utility model is such:

By the left and right sides support of the pressure spool of window screening, clamping window screening and presser bar, left and right sides gathering sill, volume spool, supporting volume spool, weight, form with rope, the weight gathering sill of coaxial rope sheave, binding weight and the rope sheave of volume spool.Window screening volume spool misalignment screen window central plane is established a thread tube below the volume spool, thread tube is connected with the left and right sides support of supporting volume spool by the adjustment bearing at two ends.Establish a directive wheel between weight and the rope sheave, directive wheel is fixed on the weight gathering sill, and rope is walked around directive wheel.Establish a stage clip on the weight, the adjustable spring limiting board in a position is established in the weight top in the weight gathering sill.Press the weight sum and the weight of spool and presser bar to be equal in weight.Below the pressure spool, the top corresponding position of screen window position-limiting tube is provided with two rectangles and bumps pearl.For the space of anti-mosquitos and flies by the window screening back side enters, below thread tube, an if rubber packing bar, weather strip is fixed on the thread tube bearing by fixed bar, when window reached maximum position, weight was fallen lowest part, established a pin-and-hole on the weight gathering sill, establish a resilient key on the weight, also establish the hand switch of a control resilient key on the weight, switch is pressed to next, and resilient key enters pin-and-hole, when switch is mentioned the extreme higher position, resilient key withdraws from, and withstands on the switch, at this moment, screen window maintains static, but can open.Close screen window, down the tension and compression spool or on carry weight, bump that pearl is closed to get final product.

Press the spool two ends to pass left and right sides gathering sill, and two ends establish an end cap respectively, in case press spool run-off the straight in the open and close process.

Use principle of the present utility model is such:

When screen window is closed, press between spool and the screen window position-limiting tube to connect by bumping pearl.At this moment, weight rises to the extreme higher position, and the stage clip on the weight is blocked by spring limiting board, and compresses, and spring has reaction force, forces the rope tensioning, thereby window screening is tightened, and in addition, the elastic force of spring can be adjusted by the position of regulating limiting plate.Open screen window, need only hold and press spool upwards to carry, overcome the frictional force of bumping between the pearl, owing to weight equates with the weight sum of pressing spool, presser bar, therefore, when weight is just opened at screen window, be subjected to the effect of spring pressure and light and slow toward falling, where just and the volume spool is rolled window screening equally light and slowly, and whole motion is very steady, and where be willing to stop stop.

The utility model result of use and technical characterstic:

1, compact conformation, reasonable

2, open, close not have in the closed procedure and impact, light, flexible

3, after screen window was closed, window screening was tightened automatically
