Description

Axle head spring type rolling door, window screening

One, technical field: the utility model relates to a kind of door, window screening, particularly a kind of axle head spring type rolling door, window screening.

Two, background technology: the mosquito-insect-proof door, the window screening that use on present various doors, the window, mostly be closed-in construction, middle dress yarn, axle page hinge and window frame link or frame inset type mounting means, this window screening is contained in outside the Door and window frame, have a strong impact on door, see warpage, crack, mosquito-insect-proof poor performance outside window.Another Self rolling screen window is " extension spring self-rolling structure " complex structure, the group external member is many, cost is high, the dynamics of curling is little, meet or exceed the long window screening of 1.2m, roll up not to the end, window screening can not all involve in the outer cover, wind-shielding function is undesirable, window screening two vertical edges are very easily deviate from the window screening munnion, have a strong impact on the mosquito-insect-proof performance.More than three kinds of different structure forms window screening all in various degree exist that practicality is not good enough, door, see not attractive in appearance, mosquito-insect-proof poor-performing outside window, the price height is unfavorable for shortcomings such as popularization.

Three, utility model content: the purpose of this utility model just be to provide a kind of simple in structure, the group external member is few, cost is low, rotations is flexible, the great efforts of curling, window screening curlingly roll up that number is many, mosquito-insect-proof, windproof well behaved roller shutter window screening---axle head spring type rolling door, window screening.During technical solution of the present utility model, described axle head spring type rolling door, window screening mainly include end cap, intracavity coil spring box, wind spring, coil spring box shaft-cup, spacing pad, pin, the munnion by windproof pearl opening, window screening axle, window screening box, left and right two vertical edges of window screening and the window screening of windproof pearl is housed and forms with the structure subitem position parts etc. that above-mentioned group of external member made one.The notch that the window screening box is installed is arranged around end cap, and the centre has the installation shaft of coil spring box and coil spring box shaft-cup, installation shaft centre that the opening crack that wind spring is installed, the installation pillow block that the coil spring box root has the coil spring box bearing are arranged.Wind spring one termination clamps in a construction opening seam and fixes, and wind spring curls and puts in the cavity type coil spring box, and it is fixing in the construction opening of processing that another termination is installed in the coil spring box cross wall.The coil spring box shaft-cup is installed concavo-convex bayonet socket by installation bayonet socket on box upper shed one end wall and shaft-cup and is attached to together afterwards, is sleeved on coil spring box, the shaft-cup axle, loads onto limiting gasket, and it is spacing to put on the opening pin.Window screening axle plug-in mounting is advanced with the window screening axle positive stop lug boss is installed on the installation base of two ends coil spring box shaft-cup and is connected, the window screening one end top that window screening two vertical edges are equipped with windproof ball is bonded on the window screening axle, two vertical edges are put in the windproof pearl vertical openings of the window screening groove in the munnion.When downward pulling window screening, wind spring takes up being wrapped in clockwise on the box axle in the coil spring box, and when unclamping window screening, wind spring oppositely rebounds, the window screening axle is backward rotation under the drive of coil spring box and coil spring box shaft-cup, can be the window screening rollback in the window screening box.That the axle head spring type rolling door of the utility model form of structure, window screening have is simple in structure, group cover accessory is few, rotate flexibly, the great efforts of revolution volume yarn, the number of turns of curling are many, mosquito-insect-proof, wind are functional, pulling, curl and rotate the many advantages of thread such as flexible, long service life, price are low.

Four, description of drawings: Fig. 1 is the sectional structure schematic diagram of the utility model embodiment axle head spring type rolling door, window screening;

Five, the specific embodiment: with reference to accompanying drawing, axle head spring type rolling door, the window screening made with the utility model structure axle head spring type rolling door, window screening are example, and the utility model mainly includes end cap (1), intracavity coil spring box (2), wind spring (3) coil spring box shaft-cup (4), spacing pad (5), pin (6) to be had munnion (7), window screening axle (8), window screening box (9), left and right two vertical edges of window screening of vertical windproof pearl opening that the window screening (10) of windproof pearl is arranged and make the structure subitem functional part parts compositions such as (11-19) of one with above-mentioned group of external member.The installation notch (17) that open type window screening box (9) is arranged around end cap (1) cylindrical, there is coil spring box (2) centre, the installation circular shaft (11) of coil spring box shaft-cup (4) has wind spring that crack (12) is installed in the middle of circular shaft (11), axle (11) root has the installation boss platform (18) of coil spring box intermediate shaft hole, in the middle of the sidewall of coil spring box (2) one sides, leave the desk-top circular shaft of evagination hole, opening perimeter cross wall one end of wind spring (2) is an opening, leave the installation bayonet socket of shaft-cup (4) on the opening, fixing installation crack (12) lining that wind spring (3) one terminations are installed on the axle (11), it is fixing on the cross wall construction opening of processing that the other end head-clamp of wind spring (3) is contained in coil spring box (2), other of wind spring (3) partly curl and put in the inner chamber of coil spring box (2), be sleeved on the axle (11) together with coil spring box (2), link the installation of big face sidewall cylindrical one end of coil spring box shaft-cup (4) recessed, the cross wall of boss threading coil spring box (2) is sleeved on the axle (11) after installing in the bayonet socket.Load onto spacing pad (5), opening pin (6) is spacing.On the single reinforcement positioning boss (14) on wind spring shaft-cup (4) the one end external diameters of the threading of the two muscle locating aperture grooves (15) on window screening central siphon (8) internal diameter two ends.The horizontal horizontal straight line of window screening (10) top one end be bonded in volume yarn axle (8) go up, window screening box (9), threading end cap (3) installation notch (17) lining all around.Putting into the window screening (10) of the vertical vertical vertical edge of windproof ball window screening is arranged, windproof pearl is open channel (7) lining vertically.When downward pulling window screening (10), wind spring (3) be wrapped in clockwise axle (11) go up rolling-in, when unclamping window screening (10), wind spring (3) oppositely rebounds on the interior cavity outer wall that is crimped onto coil spring box (2), window screening axle (8) under the reverse elastic force induced effect of wind spring (3) and coil spring box (2), shaft-cup (4) rotate together, window screening (10) is promptly involved in window screening box (9) lining by window screening axle (8), overlapping curling groove (13) lining that is deposited on the shaft-cup (4) of window screening two vertical edge edge sealing and the dislocation of windproof pearl.Upper and lower reciprocating motion like this realizes closing and doing from scrolling of window screening.

The axle head spring type rolling door of the utility model structure, window screening are applicable to and make door, window window screening, can adopt plastics or aluminum alloy materials to make the axle head spring type of this form of structure from rolling door, window screening.
