Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a push-pull pulley for aluminum alloy doors and windows. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and sashes. They are called aluminum alloy doors and windows, or aluminum doors and windows for short. Door and window pulleys are a type of pulley used on doors and windows. Sliding doors and windows equipped with pulleys do not take up indoor space and have a beautiful appearance.

[0003] After long-term use, the pulley of the push-pull sliding device will be damaged due to wear or pressure and needs to be replaced. However, the pulley is currently fixed to the inner side of the aluminum alloy door and window by bolts. However, when the pulley needs to be replaced, the operator needs to use tools to disassemble the entire shell together with multiple pulleys, and cannot remove and replace a single pulley, which makes pulley replacement inconvenient. In addition, since the pulley height is fixed, after the pulley is installed, the purchased pulley height may not match the door and window, resulting in the pulley being unable to contact the door and window frame, so that the pulley cannot be used normally, and the practicality is poor. Utility Model Content

[0021] See also Figure 1-5 , a push-pull pulley for aluminum alloy doors and windows, comprising a mounting shell 1, and a movable mechanism 2 is arranged on the surface of the mounting shell 1;

[0022] The mounting shell 1 is used for mounting and fixing with doors and windows, and the movable mechanism 2 enables the pulley 203 to be detached from the mounting shell 1 separately, and also enables the height of the pulley 203 to be adjusted.

[0023] The movable mechanism 2 includes an inner shell 201, a mounting groove 204 is provided on the surface of the inner shell 201, a connecting block 202 is slidably connected to the surface of the mounting groove 204, a pulley 203 is rotatably connected to the surface of the connecting block 202, a limiting block 205 is fixed to the surface of the mounting groove 204, a limiting groove 206 used to cooperate with the limiting block 205 is provided on the surface of the connecting block 202, a screw rod 207 is threadedly penetrated on the surface of the inner shell 201, one end of the screw rod 207 is rotatably connected to the inner wall of the mounting shell 1, and a rotating plate 211 is fixed to one side of the screw rod 207;

[0024] The pulley 203 can rotate on the surface of the connecting block 202, and the connecting block 202 can be inserted into the installation groove 204. At the same time, during this process, the limit block 205 will be squeezed and deformed, and can enter the limit groove 206, so that the connecting block 202 can obtain a positioning effect on the inner side of the installation groove 204, so that the pulley 203 can be disassembled and assembled separately from the inner shell 201, so that when a single pulley 203 is damaged, the operator does not need to replace all of the device, thereby reducing the maintenance cost of the device, and the operator can replace the pulley 203 separately without the help of tools. When the height position of the pulley 203 needs to be adjusted, the screw 207 is rotated, so that the inner shell 201 is affected by the thread and begins to move on the surface of the screw 207, so that the height positions of multiple pulleys 203 can be changed together, so that the pulley 203 can fit with the door and window frame, making the device more practical.

[0025] Further, the top height of the rotating plate 211 is lower than the top height of the pulley 203;

[0026] This ensures that when the pulley 203 contacts the door and window frame, the rotating plate 211 will not touch the door and window frame.

[0027] Furthermore, the limit block 205 is arranged in a semicircular structure, and the limit block 205 is made of rubber;

[0028] By setting the limiting block 205 , the limiting block 205 can be deformed by its own material, and it is also ensured that the limiting block 205 can enter and leave the limiting groove 206 by its own shape.

[0029] Furthermore, a guide rail 208 is fixed to the inner wall of the mounting housing 1, a slider 209 is slidably connected to the surface of the guide rail 208, and the surface of the slider 209 is fixedly connected to the surface of the inner housing 201;

[0030] When the inner shell 201 is moving, the slider 209 will be able to slide on the surface of the guide rail 208, so that the inner shell 201 can obtain a guiding effect.

[0031] Furthermore, the connection block 202 is provided with an arch structure;

[0032] By setting the shape of the connection block 202, the connection block 202 is prevented from being separated from the installation groove 204 by moving forward and backward, and the contact area between the inner shell 201 and the surface of the connection block 202 is increased, thereby increasing the friction force.

[0033] Furthermore, a connection groove 210 is provided on the surface of the connection block 202;

[0034] The connection groove 210 is provided so that the limiting block 205 has enough space to be compressed and deformed so as to enter the limiting groove 206 .

[0035] Furthermore, a hexagonal groove is provided on the surface of the rotating plate 211;

[0036] The provision of the hexagonal slot enables an operator to operate the rotating plate 211 using a hexagonal wrench.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
