Abstract
The utility model discloses a pulley with a self-locking device for aluminum doors and windows. The technical scheme is that the pulley with the self-locking device comprises a pulley casing, a pulley frame is sleeved on the pulley casing in embedded mode and provided with a pulley body, and one end of the pulley frame is provided with an adjusting screw. The pulley with the self-locking device for the aluminum doors and windows is characterized in that one end of the pulley casing is provided with the self-locking device to be connected with the adjusting screw. The self-locking device comprises a locking base fixed on the pulley casing, a locking block is sleeved at one end of the locking base in embedded mode, and the other end of the locking block penetrates through a return spring and then is sleeved on a head of the adjusting screw in embedded mode. The pulley with the self-locking device for the aluminum doors and windows has the advantages of being capable of conveniently adjusting height of window sashes and fixing gaps between the window sashes and a window frame, safe in use and the like.
Description
Technical field
The utility model relates to a kind of aluminium door sash pulley that self-locking device is arranged, and is used to support bar and in doorframe and window frame, slides.
Background technology
Existing aluminium door sash pulley mainly comprises pulley shell, pulley yoke, pulley and set screw, and the transhipment set screw can change the upright position of pulley yoke, thereby adjusts gap between bar and the frame.Because pulley is not provided with self-locking device, aluminium door and window under the state that bears a heavy burden, set screw through regular meeting because be given a shock revolution, thereby cause bar and doorframe and window frame gap to dwindle, produce and rub.Can cause the door and window can not switch when serious, the indoor person and property safety are caused very big hidden danger.
Summary of the invention
The purpose of the utility model is to address the above problem, and designs a kind of aluminium door sash pulley with self-locking device.
In order to achieve the above object; The aluminium door sash pulley of the utility model; Comprise a pulley shell, the pulley shell cover is embedded with a pulley yoke, and pulley yoke is provided with pulley; One end of pulley yoke is provided with a set screw, it is characterized in that: an end of pulley shell is provided with a self-locking device and links to each other with set screw.
The self-locking device of the utility model comprises that one is fixed on the stop pedestal of pulley shell, and an end cover of stop pedestal is embedded with a scotch; Cover was embedded in the set screw head after the other end of scotch passed a back-moving spring.
The two ends of the scotch of the utility model have a polygon projection respectively, and stop pedestal and set screw head have a hole respectively, and its shape size is complementary with the hole of stop pedestal and set screw head respectively.The limit number of projection is the 3-8 limit, and the optimum value of limit number is a hexagon.
Owing to adopted said structure, the utlity model has convenient sash height, fixed sash and window frame gap, the advantage such as safe in utilization of regulating.

The specific embodiment
Like Fig. 1, shown in Figure 2, the aluminium door sash pulley of the utility model comprises a pulley shell 1, and the middle part cover of pulley shell 1 is embedded with a pulley yoke 2, and pulley 3 is installed in the pulley yoke 2, and pulley 3 is used to support bar and in doorframe and window frame, slides.Pulley yoke 2 one ends are provided with an installing hole 4, and set screw 5 is arranged in the installing hole 4, are used to adjust the gap between bar and the frame.The head of set screw 5 is provided with a polygonal hole 6, and is as shown in Figure 3, and the limit number is the 3-8 limit, and the optimum value of limit number is a hexagon, and its size is complementary with the projection 8 of scotch 7 one ends.Projection 8 passes a back-moving spring 9, is inserted in the polygonal hole 6, and fixing.The other end of scotch 7 has another polygon projection 10, and is as shown in Figure 4, and the limit number is the 3-8 limit, and the optimum value of limit number is a hexagon, and the hole 12 on its size and the stop pedestal 11 as shown in Figure 5 is complementary.One through hole 13 is arranged on the stop pedestal 11, can put into adjustment means (figure does not draw) and regulate scotch 7.Stop pedestal 11 is fixed on the pulley shell 1.
During use, under back-moving spring 9 effects, scotch 7 contacts with stop pedestal 11, and projection 10 receives hole 12 restrictions, and set screw 5 receives scotch 7 restrictions, even bar heavy burden horizontal slip can not turned round.When adjustment doors sash height, use adjustment means to pass through hole 13, extruding scotch 7, thus compression reseting spring 9 makes scotch 7 separate with stop pedestal 11; The pivot stop piece 7 again, and drive set screw 5 rotations, and the bar that pulley 3 supports is transferred to proper height.Remove external force, let back-moving spring scotch 7 pushed back stop pedestal 11, realize locking 9.
