Abstract
Disclosed is a door and window pulley, which comprises a fixing plate, a pulley fixing frame, a pulley and an adjusting screw. The fixing plate is provided with an adjusting screw hole that is arranged on a plate on the upper side of fixing plate which is perpendicular to the fixing plate; the adjusting screw is screwed inside the screw hole; the end part of the adjusting screw contacts with the pulley fixing frame; the pulley is arranged between two vertical plates that form the pulley fixing frame; a sliding slot is arranged under the adjusting screw hole on the fixing plate; both sides of one vertical plate of the pulley fixing frame are arranged inside the sliding slot; the section of the pulley fixing frame is in a shape of letter n. The advantages are that the utility model increases the solidness of door and window pulley, and the pulley will not be jammed when adjusted; the utility model is convenient to adjust with a wide adjustment range.
Description
Technical field
The utility model relates to the pulley field, relates to be installed in the door and window trolley on the door and window in particular.
Background technology
More flexible when the installation pulley can make door and window at switch on the door and window, in installation process,, door and window well is installed in the doorframe by regulating the position of pulley in its fixed head.But the pulley that has at present is inconvenience when regulating, and adjustable range is little, is unfavorable for the installation and the mode of door and window, and stuck phenomenon appears in its structure of the pulley that has insecure easy damage in use easily.As application number is 01206532, the applying date is June 13 calendar year 2001, denomination of invention is a door and window trolley, it comprises the external fixation folder, be contained in the fixed axis in the external fixation folder, be contained on the fixed axis and can take turns folder around the interior activity that fixed axis rotates, the movable wheel pressed from both sides in roller was contained in, it is characterized in that the adjusting screw is arranged on the external fixation double wall, its termination contacts with interior movable wheel folder adjusting wall after regulating the bolt threaded one end and revolving the external fixation folder and regulate screw.The door and window trolley adjustable range of this kind structure is little, owing to be to slide in groove by axle to realize the adjusting of pulley, its adjustment structure is insecure, is easy to damage and occur easily stuck phenomenon, regulates inconvenient.
Summary of the invention
The purpose of this utility model is exactly that a kind of adjustable range that provides in order to solve top described deficiency is big, sound construction and door and window trolley easy to adjust.
The technical solution that the utility model adopts in order to achieve the above object is as follows:
Door and window trolley, comprise fixed head, pulley fixed frame, pulley and adjusting bolt, on fixed head, be provided with the adjusting screw, regulate screw and be arranged on the fixed head upside plate vertical with fixed head, regulate the bolt spiral in this screw, its end contacts with pulley fixed frame, pulley is installed between two risers that constitute pulley fixed frame, be provided with sliding tray below fixed head adjusted screw, pulley fixed frame one riser both sides place in this sliding tray, and the cross section of described pulley fixed frame is " n " type.
The utility model also can be done following technological improvement:
Regulating the boss that the screw place is fixed with the band screw.
Be positioned on fixed head one side at pulley fixed frame and be provided with projection.
Be provided with the installing plate reverse and vertical in the bottom of fixed head, on installing plate, also be provided with installing hole with pulley.
Be provided with the stiffener perpendicular in the both sides of fixed head with fixed head.
The technique effect that the utility model adopts said structure to reach is:
1, adjusting device is to slide in sliding tray by the riser that constitutes pulley fixed frame to realize the adjusting of pulley, has increased the fastness of door and window trolley, also stuck phenomenon can not occur when regulating pulley;
2, easy to adjust and adjustable range is big, only need turn bolt with screwdriver can regulate the position of pulley in fixed head at an easy rate, by strengthening the length of sliding tray, just can be suitable add wide adjusting range.
3, be positioned at set projection on fixed head one side at pulley fixed frame, can prevent effectively that pulley fixed frame from skidding off fixed head when regulating;
4, install the boss that has screw again additional at adjusting screw place, improved the supporting capacity of screw when regulating, thereby strengthened the firm intensity of door and window trolley.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, door and window trolley, comprise fixed head 1, pulley fixed frame 2, pulley 3 and adjusting bolt 4, be provided with the plate 11 perpendicular at fixed head 1 upside with fixed head 1, on this plate 11, have and regulate screw 12, below this adjusting screw 12, install the boss 5 that has screw again additional, the screw of boss 5 connects with adjusting screw 12, can increase the supporting capacity of fixed head 1 adjusted screw 12 when regulating, strengthen the fastness of fixed head 1, below fixed head 1 adjusted screw 12, be provided with sliding tray 13 in couples, pulley fixed frame 2 is made of two risers, pulley fixed frame 2 slides in the sliding tray 13 of fixed head 1 by a riser, can increase the fastness of door and window trolley so on the one hand and can prevent that stuck phenomenon from appearring in pulley fixed frame 2 when regulating, on the other hand, the adjustable range of pulley fixed frame 2 is also very big, it can add wide adjusting range by the length that increases sliding tray 13, described pulley fixed frame 2 constitutes the cross section by two risers and is " n " type, pulley 3 is installed between two risers that are " n " type, regulate bolt 4 spirals in above-mentioned two screws that communicate, its end contacts with pulley fixed frame 2, pulley fixed frame 2 is positioned at fixed head 1 one sides and is provided with projection 21, it can prevent effectively that pulley fixed frame 2 from skidding off fixed head 1 when regulating, when regulating, turn adjusting bolt 4 with screwdriver, regulate bolt 4 the moving up and down of spiral under the effect of regulating screw 12, when adjusting bolt 4 moves downward, just but propelling sheave fixed mount 2 moves downward, when bolt 4 moves upward, regulating bolt 4 just breaks away from pulley fixed frame 2, pulley fixed frame 2 moves upward under the action of gravity of door and window, thereby pulley fixed frame is played convenient purpose of regulating, be provided with the installing plate 14 reverse and vertical with pulley 3 in the bottom of fixed head 1, on this installing plate 14, also have installing hole 15, also be provided with the stiffener 16 perpendicular with fixed head 1 in the both sides of fixed head 1, they can play the effect of reinforcement to fixed head 1.
