Abstract
The utility model relates to a screen door and window pulley which comprises a shell and a pulley riveted in a shell slot. An oblique positioning reed extends from the top of the shell, an elongated slot bore is arranged in the top of the shell, and a positioning reed extends from a side hole edge. The width of the positioning reed is less than or equal to that of the elongated slot bore, while the length of the positioning reed is less than or equal to that of the elongated slot bore. An angled elastic connecting arm downward extends from one end of the shell. The product shell, the positioning reed and the elastic connecting arm are sheet metal material which is integrally formed by punch forming, which saves supporting steel wires, springs, assembly process, connecting arm rivets and riveting process thereof. The production efficiency is raised greatly, the raw material is saved, and the production cost is reduced further. The utility model has the advantages of simple structure, reliable and accurate integral type reed positioning, no vibration, high product performance and long service life.
Description
Technical field
The utility model relates to a kind of slide door or window pulley, particularly a kind of screen door sash pulley.
Background technology
In the prior art, that China Patent No. 02258267.3 discloses is a kind of the screen door sash pulley assembly of easy adjusting " can ", comprise housing and be arranged at the interior pulley body of housing, make pulley body protrude in housing bottom, be characterized in that a side laterally is provided with cylinder card knot end above the housing, make this card knot end protrude from the housing both sides, the housing opposite side is convexly equipped with a support piece, this support piece is slightly less than card knot end width, and is provided with a screw on the support piece, and spiral shell is established a screw on screw.When this pulley assembly is inserted in the screen window bottom horizontal frame, can locate by card knot end, and can be by screw contact bottom horizontal frame, making whole pulley assembly is the center rotation displacement according to card knot end, and reaches the purpose of just regulating of pulley assembly.Its structure is complicated, and materials are more, and cost is higher.Other has a kind of screen door window glidewheel of designs simplification, and as shown in Figure 1, it comprises the pulley 2 of housing 1 and riveted joint, and the end riveted joint of housing has linking arm 3, and the case top two ends are provided with porose, and card is established supporting steel wire spring 4 in the hole.Its housing, linking arm, supporting steel wire spring are three independently parts, have still that materials are more, the process and assemble operation is many, labor productivity is lower, the cost problem of higher.The supporting steel wire spring easily produces and rocks, and properties of product are had certain influence.
The utility model content
It is a kind of simple and reasonable that the purpose of this utility model is to provide, and production process is few, and materials are economized, and cost is low, and the screen door window glidewheel of long service life is to overcome weak point of the prior art.
By a kind of screen door window glidewheel of this purpose design, comprise housing and be riveted on pulley in the enclosure slot that its architectural feature is that the end face of housing extends a positioning reed that tilts.
Described housing end face is provided with a long slot bore, and a side opening edge extends positioning reed; The width of positioning reed is less than or equal to the width of long slot bore, and the length of positioning reed is less than or equal to the length of long slot bore.Described housing one end extends the elasticity linking arm of bending downwards.
Housing of this product and positioning reed, elasticity linking arm are the monolithic of metal sheet integrated punching moulding, supporting steel wire spring of the prior art and assembly process thereof have been saved, the rivet and the staking process thereof of linking arm have been saved, production efficiency improves by a relatively large margin, saved raw material, cost of production further descends.Its simple and ingenious structure, the accurate positioning of monolithic positioning reed is reliable, can not rock, and properties of product are improved, and prolong application life.
Description of drawings
Fig. 1 is the structural representation of existing screen door window glidewheel.
Fig. 2 is the structural representation of the utility model one embodiment.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 2, this screen door window glidewheel comprises housing 21 and is riveted on pulley 22 in the enclosure slot that the housing front is subtriangular, and pulley is riveted on triangle central authorities top.Housing 21 end faces are provided with a rectangle slotted eye 25, one side opening edge and extend acclivitous positioning reed 24; The width of positioning reed less than or near the width of rectangle slotted eye, the length of positioning reed less than or near the length of rectangle slotted eye.Housing 21 1 ends extend the elasticity linking arm 23 of bending downwards.Housing 21 is the monolithic of metal sheet integrated punching moulding with positioning reed 24, elasticity linking arm 23.Pulley 22 can be plastic wheel or metal wheel.
Same as the prior art during use: the intraperitoneal that this pulley is placed screen door window aluminium extruded sections, one end of dihedral holder is provided with projection, the elasticity linking arm of projection and this pulley is hinged, and positioning reed is resisted against aluminium extruded sections inner top surface location, and adjustment screw is resisted against the housing end face.When needs are adjusted the pulley high and low position, rotate adjustment screw, pulley is rotated around hinged projection, can realize the adjusting of pulley high and low position, very easy.
