Abstract
The utility model relates to a gravity self open curtain winder. The gravity self open curtain winder uses the gravity of a weight dropper installed on a guide rail to make a rotatable drum installed on a supporting base fixed shaft rotate by a pull line and drive a steel strip embedded into the drum to wind a window screen or the cloth stuck on the steel strip along a guiding block and a guide rail on the rotatable drum. When the window screen and the cloth are pulled downwards, the window screen and the cloth are blocked off a window and a door, the weight dropper is lifted to store the energy for winding once more and then the steel strip is pressed by a stop strip to fix the window screen or the cloth. The utility model can be installed on windows, doors, foods and meat safes to replace traditional screen doors and windows to save the material and the labor. The utility model has the characteristics that the gravity self open curtain winder is installed only by setscrews and is opened and closed in a small vertical plane, and the occupation area is small. The gravity self open curtain winder can also be used for a curtain and the door of the bathroom of the household.
Description
The utility model be a kind of utilize gravity can the automatic winding window screening, the roller shutter utensil of cloth.Be installed on the housing window and food, meat safe door on replace traditional screen door window or door, curtain.
Traditional screen door window is to be formed with hinge-coupled by door and window outside framework and the doorframe and window frame of coveing with window screening; Switch takies than large space all around hinge axis, and trouble is expected, taken a lot of work, installs to expense.
The purpose of this utility model is will provide a kind of can save door and window outside framework and doorframe and window frame; Window screening or cloth are vertically moved up and down rolling; Device easy for installation.
The purpose of this utility model is achieved in that utilizes the gravity that is installed in weight in the guide rail, make by stay cord to be installed in that rotating reel rotates on the bearing fixed axis, and drive the steel band that embeds reel be bonded at window screening on the steel band or cloth along guide pad along the guide rail rolling to reel.Then launch window screening when pulling down or cloth blocks door and window, and promote weight and do energy storage, push down steel band with fixedly window screening or cloth with bar only again for rolling once more.
The utility model is owing to be window screening or cloth to be done to launch in vertical plane or rolling is moved, so it is little to take up room, saved Door and window frame and, framework outside window.Bearing and guide rail only need just can fix with setscrew, and be easy for installation.
The utility model is as shown in the figure: 1, guide pad; 2, weight; 3, guide rail; 4, end bar; 5, cheese; 6, nylon bearing; 7, axle; 8, steel band; 9, plastic window screening; 10, reel; 11, bearing; 12, pulley; 13, stay cord; 14, draw shelves.
To be the gravity that utilizes weight 2 drive reel 10 by stay cord 13 through the torque that pulley 12 break-ins are produced on the cheese 5 that is fixed together with reel 10 to the utility model, and on axle 7, rotate by the nylon bearing 6 that is fixed together with reel, thereby rolling embeds the steel band 8 of 10 li on reel, and by the steel band band the window screening 9 that is bonded on the steel band together rolling to reel, up to steel band 8 lower ends be fixed together draw the shelves 14 1 time transverse plane of guide pad that in guide rail 3, are fixed on guide rail 3 upper ends to block till.Guide pad is the prism nylon block that two mutual vertical planes and a garden arc surface are surrounded, its installation site as A among the figure to shown in the view.Axle 7 is installed in bearing 11 axis holes, fixes with holding screw.When drawing shelves 14, when guide rail 3 pulled down, then steel band band in both sides window screening and is moved down for 3 li at guide rail along guide pad 1, and the both sides weight upwards slides along guide rail.When window screening all blocks door and window, then embed in the guide rails ending bar 4, utilize and end that two ends hang over the elastic compression steel band that the finer wire on the guide rail lug produces on the bar 4, not only prevented make progress rolling but also the steel band window screening is pressed on insects such as preventing mosquitos and flies on the guide rail enters of window screening.One of the finer wire that ends two ends on the bar only penetrates that in the hole riveting jail on the bar, and the other end curves the right angle and inserts from upper and lower two directions respectively and only make the guide rail epirelief earhole that bar can rotate around the two hole lines of centres; Finer wire is crooked arc in ending the bar sagittal plane; Make and produce elastic force when only bar embeds guide rail steel band slideway.As among the figure 4 and C-C shown in.Bearing 11, pulley 12, guide rail 3 are all fixed with setscrew.Guide rail, reel all draw with aluminium alloys, and wall thickness should be below 1mm, and steel band is answered annealed condition, and head is formed by two riveted joints, go out so that the on-slip of reel rear defence is gone in the intercalation of formation barb.Shown in B-B.When width can only save one of centre with two steel bands during less than 1m; When width increases, can come adhesion 2 or 3 width of cloth window screening or clothes with wide strip bar number in the middle of increasing because guide rail is fixing shown in C-C in the weight slideway with setscrew, thus weight inside one side should stay a groove in order to avoid bump screw and take place stuck.Both ends of the surface have two nylon6 chips similar and bigger to the weight cross section in case weight and guide rail rub about weight.
Claims (6)
1, gravity is to utilize the potential energy of weight to come the utensil of rolling window screening and cloth from opening screen-roller.It is characterized in that utilizing the gravity that is installed in weight in the guide rail, make by stay cord to be installed in that rotating reel rotates on the bearing fixed axis, and drive the steel band that embeds reel be bonded at window screening on the steel band or cloth along guide pad along the guide rail rolling to reel.Then launch window screening when pulling down or cloth blocks door and window, and promote weight and do energy storage, push down steel band with fixedly window screening or cloth with bar only again for rolling once more.
2, screen-roller according to claim 1 is characterized in that the steel band head makes barb type, can not come off in case the reel slot is gone in intercalation.
3, screen-roller according to claim 1 is characterized in that when this utensil width during greater than the window screening or the cloth bin gate width of cloth, and wide strip bar number comes two of adhesions or three door width of cloth window screenings or cloth in the middle of can increasing.
