Description

Technical Field

[0001] The invention relates to the field of screen window manufacturing and processing, and in particular to an aluminum alloy sunshade screen window used for vehicles, ships and the like. Background Art

[0002] Pleated screens are generally used on windows of houses, cars, ships, etc. to block the sun and mosquitoes.

[0003] The pleated curtain screen is mainly composed of left and right side rails, upper and lower rails, a movable rail and a window screen, wherein the left and right side rails and the upper and lower rails are fixedly connected by an angle wrap, one end of the window screen is fixed to the upper rail or the lower rail, and the other end of the curtain body is connected to the movable rail, and the movable rail slides up and down along the side rails. Usually, multiple wires are passed through the window screen, two of which are respectively embedded in the left and right side rails, and the two wires directly pass through the window screen and the movable rail, and are located on both sides of the window screen. The wires also include one end fixed to the angle wrap at the lower left corner or the lower right corner of the pleated curtain screen, and the other end moves upward along the side rail, and then horizontally penetrates into the movable rail, after moving horizontally for a certain distance in the movable rail, passes out of the movable rail, and then vertically passes through the window screen upward, and the wire fixed to the upper rail guides, positions and limits the up and down movement of the movable rail and the curtain body, prevents the movable rail and the window screen from offset when moving, and keeps the window screen stably in an open or closed state.

[0004] When the movable rail is pulled to drive the window screen to open or close, the edge of the wire hole of the movable rail will rub against the wire, and the wire will be worn off after long-term use. At the same time, long-term use will reduce the elasticity of the wire, the wire will become loose, and the length will increase, and the force of the wire on the movable rail will be reduced, making the movable rail and the window screen loose, affecting the use. Usually, a tensioning mechanism is set in the wrapping angle, and when the wire becomes loose, it is adjusted by opening a screw hole in the box cover, screwing a stud into the screw hole, manually winding the head of the pull wire around the outer wall of the stud, and then tightening the stud downward with a screwdriver or other tools to tighten the pull wire. The operation is troublesome, and the pull wire and the stud are easy to loosen, and the tensioning reliability is poor. Summary of the invention

After the adjustment, the angle of the shaft sleeve is adjusted so that the shaft sleeve can be embedded in the polygonal hole, and the elastic member pushes the shaft sleeve back into the polygonal hole to clamp the shaft sleeve, prevent the shaft sleeve from rotating, and release the wire around it. The above adjustment method is simple, effective, and can keep the screen window stably at the adjusted tightness.

[0008] Preferably, cavities are opened inside the upper and lower rails and the left and right rails, and two movable rails are arranged between the upper and lower rails, and the two movable rails are movable rail one and movable rail two respectively, and blocking caps are connected to both ends of movable rail one and movable rail two respectively, and the blocking caps are embedded in the cavities of the left rail and the right rail, and the blocking caps are detachably connected to the left and right rails, and a plurality of fixed blocks are respectively clamped in the cavities of movable rail one and movable rail two, and the upper and lower ends of the window screen one are respectively embedded in the cavities of the upper rail and movable rail one, and the two ends of the window screen one are respectively connected to the top wall of the upper rail cavity and the fixed blocks of the movable rail one cavity, and the fixing method of the window screen two to the lower rail and movable rail two is the same as that of the window screen one.

After the polygonal cap top is pushed out of the polygonal hole with an angle, the polygonal cap top is rotated, and the polygonal cap top drives the shaft sleeve to rotate, and the guide wire is wound up. After adjustment, the angle of the polygonal cap top is adjusted so that the sides of the polygonal cap top are aligned with the sides of the polygonal hole. The spring rebounds to push the polygonal cap top into the polygonal hole, and the polygonal cap top is stuck.

[0012] Preferably, two card slots are respectively provided on the two side surfaces of the movable rail, the blocking cap includes a connecting block, the connecting block has a cavity, and two card strips 1 and 2 are respectively integrally formed on both sides of the connecting block, the card strips 1 and 2 are elastic, and there are two card strips 1 and two card strips 2 respectively, the end of the movable rail is located between the two card strips 1, and the two card strips 1 are respectively inserted into the card slots 2 on both sides of the movable rail, the end of the movable rail, the connecting block and the two card strips 2 are all embedded in the cavities of the left and right rails, the card strip 2 is slidably connected to the side rails, the distance between the two card strips 2 is greater than the distance between the inner walls of the side rail cavities, and the upper and lower sides of the connecting block and a side close to the movable rail are respectively provided with wire holes.

[0013] By adopting the above technical solution, when the blocking cap is connected to the left and right side rails, the two clamping strips 2 of the blocking cap are brought close to each other to generate elastic force, and the two clamping strips are inserted into the cavity of the side rails.

Enter the cavity of the upper rail and be fixed on the inner wall of the cavity of the upper rail. When the movable rail is pulled to drive the window screen to expand or contract, the pulleys on the movable rail and the blocking cap will generate force with the wire. The force between the pulley and the wire causes the pulley to rotate, avoiding relative movement between the wire and the pulley, thereby generating friction, causing damage to the wire and reducing the durability of the wire. When adjusting the tightness, the shaft sleeve is rotated to wrap the wire around it, so that the wire is tightened, the tension is increased, and the radial force of the wire on the pulley is increased, thereby increasing the resistance to the movement of the movable rail.

[0037] Working principle: when the magnetic strips of the two moving rails are attracted to each other and the two moving rails are connected together, the moving rails are pulled to stretch and open one window screen, while the other window screen will shrink and close, so that the screen window can be in a sunshade state or a mosquito-proof state; when the two moving rails are separated, the two moving rails are pulled to move away from each other and approach the upper rail 3 and the lower rail 4 respectively, so that the window screen 1 and the window screen 2 are folded up and stored in the cavities of the upper rail 3 and the lower rail 4 respectively, so that the screen window is in an unobstructed state, and when the moving rails are pulled, the pulleys on the moving rails and the blocking cap will generate a force with the guide wire, and the force between the pulley and the guide wire causes the pulley to rotate, avoiding relative movement between the guide wire and the pulley, thereby generating friction, causing damage to the guide wire, and reducing the durability of the guide wire; when adjusting the tightness of the window screen, use a 12-bit screwdriver to insert the blade of the 12-bit screwdriver into the The polygonal cap is inserted into the bolt groove of the polygonal cap top, the polygonal cap top is pushed, and the shaft sleeve 13 is driven to slide on the support shaft 14, and the spring 15 is compressed. After the polygonal cap top is pushed out of the polygonal hole 20 of the wrapped angle, the polygonal cap top is rotated, and the polygonal cap top drives the shaft sleeve 13 to rotate. The shaft sleeve 13 wraps the guide wire around it, tightens the guide wire, increases the tension, and increases the radial force of the guide wire on the pulley, thereby increasing the resistance to the movement of the moving rail, avoiding that when the window screen is opened on a moving car, the window screen is too loose and closed by external force, or the screen window cannot be stably maintained in the sunshade state or the mosquito shielding state, affecting the use. After adjustment, adjust the angle of the polygonal cap top so that the sides of the polygonal cap top are aligned with the sides of the polygonal hole 20. The spring 15 rebounds and pushes the polygonal cap top into the polygonal hole 20, jams the polygonal cap top, prevents the shaft sleeve 13 from rotating, and releases the guide wire on the body.
