Abstract
Description
Technical Field
[0001] The utility model relates to the field of pulley structures, in particular to a novel pulley structure used in aluminum frames of doors and windows. Background Art
[0002] The pulley allows the door and window frames to slide smoothly on the frame, which is convenient for users to open and close the doors and windows. In the prior art, the pulley is usually fixed to the bottom of the door and window frame by screws. Therefore, the pulley needs to bear the weight of the doors and windows while sliding on the track. The pressure on the pulley is relatively large, which increases the friction between the pulley and the track. As time goes by, the pulley is easily worn due to the friction. According to the degree of wear, the contact area between the pulley and the track increases when the pulley rotates, and the friction between the two gradually increases, so that the external force used by the user to push the doors and windows also increases accordingly. Therefore, the pulley needs to be maintained or replaced. In the prior art, when replacing or maintaining the pulley, the doors and windows with the damaged pulley need to be separated from the track. Although it is convenient for users to lift the doors and windows from the track, the pulley is at the bottom of the door and window frame, and users need to place the doors and windows on the ground to facilitate the removal of the pulley. However, the weight of the doors and windows themselves is relatively large, and the doors and windows also have a certain length. When users operate, it is easy for the weight of the doors and windows to be too heavy or the center of gravity is unstable when lifting the doors and windows, which may damage the doors and windows. Utility Model Content

DETAILED DESCRIPTION
[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0020] like Figure 1-6 A new type of pulley structure for doors and windows aluminum frames is shown, including a mounting plate 2 and a plurality of pulley bodies 7. A movable plate 10 is provided below the mounting plate 2. The movable plate 10 is installed at the bottom of the door and window frame by screws so that the pulley can be stably connected to the mounting plate 2.
[0021] Two symmetrically arranged dovetail grooves 9 are provided on the top of the movable plate 10, and two symmetrically arranged dovetail blocks 6 are installed on the bottom of the mounting plate 2 by screws. The dovetail blocks 6 are matched and installed inside the dovetail grooves 9. When removing the pulley, it is only necessary to pull the movable plate 10, and the dovetail grooves 9 on the movable plate 10 slide on the dovetail blocks 6, which facilitates the removal of the movable plate 10 from the mounting plate 2 and the user's operation. When installing the pulley, it is only necessary to install the movable plate 10 on the dovetail block 6 through the dovetail grooves 9, which facilitates the installation and removal operations of the pulley by the staff.
[0022] A plurality of pulley bodies 7 are all mounted on the bottom of the movable plate 10 by screws, and the two ends of the mounting plate 2 and the movable plate 10 are connected by a positioning mechanism, and the positioning mechanism includes a fixed block 8, and the fixed block 8 is connected to the movable plate 10 by screws. A plurality of plug holes 13 are provided on the surface of the fixed block 8, and plug rods 15 are inserted inside the plug holes 13. A mounting block 14 is installed between the tops of the plurality of plug rods 15 by screws, and a plurality of sliding tubes 18 are installed on the top of the mounting block 14 by screws. A fixing rod 17 is inserted at the top of the sliding tube 18, and the top of the fixing rod 17 is connected to the mounting plate 2 by screws. A compression spring 16 is movably sleeved between the surfaces of the sliding tube 18 and the fixing rod 17, and the two ends of the compression spring 16 are respectively mounted on the surfaces of the mounting block 14 and the mounting plate 2 by screws. A first mounting groove 11 is provided at the bottom of the mounting plate 2, and a second mounting groove 12 is provided at the top of the movable plate 10. The first mounting groove 11 and the second mounting groove 12 are connected, and the fixed block 8 is located inside the second mounting groove 12, and the plurality of fixing rods 17 are located in the first mounting groove. Inside the groove 11, when the pulley is disassembled, it is necessary to first pull up the mounting block 14, and the mounting block 14 pushes the sliding tube 18 upward to slide on the fixed rod 17, and at the same time, the length of the compression spring 16 shrinks, and the mounting block 14 drives the multiple insertion rods 15 to move out from the multiple insertion holes 13 of the fixed block 8, which facilitates the separation of the insertion rods 15 and the fixed block 8. After the insertion rods 15 at both ends of the movable plate 10 are moved to the top of the fixed block 8, the movable plate 10 is pulled, and the movable plate 10 is separated from the mounting plate 2, and the removal operation of the pulley can be completed; When installing the pulley, it is also necessary to pull up the mounting block 14 first. After the mounting block 14 drives the insertion rod 15 to move into the first mounting groove 11, the movable plate 10 can be installed on the dovetail block 6. After the sockets 13 on the fixed blocks 8 at both ends of the movable plate 10 correspond to the positions of the insertion rods 15 at both ends of the mounting plate 2, the action on the mounting block 14 can be cancelled. At this time, the compression spring 16 pushes the mounting block 14 through its own force, and the mounting block 14 drives the insertion rod 15 to be inserted into the socket 13, thereby completing the fixing operation of the pulley.
[0023] The bottom of the mounting plate 2 is fixed with a side plate 3 by screws. The two side plates 3 are symmetrically arranged on both sides of the pulley body 7. The bottom of the side plate 3 is higher than the bottom of the pulley body 7. A plurality of support members 5 are arranged between the two side plates 3. The bottom of the support member 5 extends to the bottom of the side plate 3. The two ends of the support member 5 are provided with a first threaded hole 19 and a second threaded hole 20. The sides of the two side plates 3 are provided with a third threaded hole. The insides of the two third threaded holes and the two second threaded holes 20 are threadedly inserted with a screw 4. The two side plates 3 are used to protect the pulley, and the screw 4 is connected to the two second threaded holes 20, at this time, the bottom of the support member 5 is in contact with the adjacent track or the ground. At this time, after the pulley is taken out, the multiple support members 5 can support the doors and windows, preventing the bottom of the doors and windows from contacting the track and requiring the user to lift them, thereby saving the user's operating steps and labor, and further facilitating the user's operation; when the screw rod 4 is connected to the two first threaded holes 19, the bottom of the support member 5 is separated from the adjacent track or the ground. After the bottom of the support member 5 moves to the upper position of the bottom of the pulley, the doors and windows can be conveniently moved on the track through the pulley.
