Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] First embodiment:

[0044] like Figure 1 As shown, the first embodiment of this utility model provides a clamping and fixing pulley structure for doors and windows, including a housing 1, a pulley assembly 2, a fixing member 3, and an adjusting member 4. The housing 1 is mounted on the door / window profile, providing a mounting base for the pulley assembly 2. The pulley assembly 2 is mounted on the housing 1 to support the door / window and drive its movement. The fixing member 3 and the adjusting member 4 are both mounted on the housing 1, and their mutual cooperation achieves clamping and fixing of the entire pulley structure.

[0045] like Figure 2As shown, in this embodiment, the bottom of the outer shell 1 is recessed towards the top to form a hollow inner cavity 101, which provides installation space for the pulley assembly 2. Furthermore, the top of the outer shell 1 has a clearance hole 102 communicating with the hollow inner cavity, which, in conjunction with the hollow inner cavity 101, provides installation space for the fixing member 3. An oblique guide groove 103 is formed on the side wall of the outer shell 1, which is used for sliding engagement with the fixing member 3 to clamp and fix the entire pulley structure. One end of the outer shell 1 (i.e....) Figure 2 An adjustment hole 104 is provided at the left end of the fixed part 3. The adjustment hole 104 is used to install the adjustment component 4, so that the movement adjustment of the fixed part 3 can be achieved by using the adjustment component 4.

[0046] In the above embodiments, preferably, the outer shell 1 is integrally formed, thereby improving the structural strength of the outer shell 1. In other embodiments, the outer shell 1 can also be configured as a combination structure of multiple components as needed.

[0047] like Figure 1 As shown, in this embodiment, the pulley assembly 2 is installed inside the hollow inner cavity 101 of the housing 1. Specifically, as... Figure 2 As shown, the pulley assembly 2 includes an inner shell 21, a connecting pin 22, a pulley 23, a nut block 24, a height bolt 25, a brush box 26, and a brush 27.

[0048] In this embodiment, the inner shell 21 is disposed within the hollow inner cavity 101, and the inner shell 21 is composed of two parallel inner shell plates 210. Each inner shell plate 210 has a positioning hole 211 on its surface, and the positioning holes 211 of the two inner shell plates are aligned. Correspondingly, a groove 105 is formed on the outer shell 1 at a position corresponding to the positioning hole 211 for engaging with the connecting pin 22. Furthermore, each inner shell plate 210 also has a pulley mounting hole 212 on its surface for mounting pulleys 23. In this embodiment, each inner shell plate 210 has two pulley mounting holes 212, thus enabling the mounting of two pulleys 23, but this number is not limited and can be adjusted as needed.

[0049] like Figure 2 As shown, the nut block 24 is disposed at one end of the inner shell 21 (i.e. Figure 2 The height bolt 25 is located at one end of the outer casing 1 (i.e., the left end of the casing 1). Figure 2 (Left end of the middle). The height bolt 25 is threadedly connected to the nut block 24. Rotating the height bolt 25 can drive the inner shell 21 along the inclined groove 105 to adjust the height of the pulley through the nut block 24. The brush box 26 is installed on the inner shell 21 and is located outside the pulley 23; correspondingly, the brush 27 is installed on the brush box 26.

[0050] During assembly, first, place the two inner shell plates 210 in parallel; then, insert the rollers of the pulley 23 into the pulley mounting holes 212 of the two inner shell plates 210; then, pass the connecting pin 22 through the inclined groove 105 and the positioning hole 211 in sequence; finally, thread the height bolt 25 to the nut block 24, so that by rotating the height bolt 25, the inner shell 21 can be adjusted to a suitable height along the inclined groove 105 by the nut block 24.

[0051] like Figure 2 As shown, the fixing member 3 in this embodiment is a sheet-like structure. It is disposed within the hollow inner cavity 101 of the outer casing 1 and located within the clearance hole 102. The bottom of the fixing member 3 has a guide portion 31, which slides into the inclined guide groove 103. Furthermore, the top of the fixing member 3 has an abutment 32, which abuts against or separates from the inner wall of the profile to clamp and fix the entire pulley structure. Additionally, limiting protrusions 106 are provided on both sides of the top of the outer casing 1 for inserting the outer casing 1 into the mounting groove 110 of the profile.

[0052] Specifically, such as Figure 2 As shown, the fixing member 3 has a threaded hole 301, and the adjusting member 4 is an adjusting bolt. The adjusting bolt 4 is rotatable but not movable relative to the adjusting hole 104 of the outer casing 1, and is threadedly engaged with the threaded hole 301. Thus, by rotating the adjusting bolt 4, the guide part 31 can be driven to move obliquely downward along the inclined guide groove 103 (i.e., from...). Figures 3 to 4 (in the state of) so that the top 32 abuts against the inner wall of the mounting groove 110 of the profile, thereby causing the top surface of the outer shell 1 to adhere tightly to the top of the mounting groove of the profile 100, thereby achieving clamping and fixing of the entire pulley structure.

[0053] Furthermore, to ensure that the adjusting bolt 4 can be rotatably but not movable relative to the adjusting hole 104 in the housing 1, in this embodiment, a limiting insertion hole 107 is also provided on the top of the housing 1 near the clearance hole 102. A limiting member 5 is inserted into the limiting insertion hole 107, and a limiting slot 51 is provided on the limiting member 5. Correspondingly, a first limiting groove 41 is provided on the outer wall of the adjusting member 4, and the first limiting groove 41 engages with the limiting slot 51 to limit the relative movement of the adjusting member 4 and the housing 1. More preferably, a second limiting groove 251 is provided on the outer wall of the height bolt 25, and the second limiting groove 251 engages with the limiting slot 51 to limit the relative movement of the height bolt 25 and the housing 1.

[0058] ③ Assemble pulley assembly 2 and install it in the corresponding area of ​​housing 1 to form a complete clamping and fixing pulley structure;

[0059] ④ Insert the complete housing of the clamping and fixing pulley structure into the profile 100, that is: Figure 3 The state shown;

[0060] ⑤ By turning the adjusting part 4 with a tool (e.g., an Allen wrench), the guide part 31 moves downward along the inclined guide groove 103, thereby driving the top part 32 to push against the inner wall of the profile 100, thus achieving the firmness of the pulley installation.

[0061] (II) Disassembly Process

[0062] ① By using a tool (e.g., an Allen wrench) to twist the adjusting part 4 in the opposite direction, the guide part 31 moves upward along the inclined guide groove 103, thereby causing the top part 32 to disengage from the inner wall of the top profile 100; at this time, the complete clamping and fixing pulley structure and the profile 100 are in a state of relative movement.
