[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] In the description of this utility model, it should be noted that the terms "vertical," "upper," "lower," and "horizontal," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0041] like Figures 1 to 3 As shown, in one embodiment of the present invention, a pulley with adjustable installation position is provided, comprising: a housing 10, a pulley assembly 20, a first adjustment assembly 30, and a connector 40; wherein the pulley assembly 20 is arranged on the housing 10, and the first adjustment assembly 30 is arranged on the housing 10; the connector 40 is a screw, and the connector 40 is arranged on the first adjustment assembly 30. As shown in the figure, the housing 10 is mounted to the bottom surface of the profile through the connector 40 to install the pulley; the first adjustment assembly 30 is used to drive the connector 40 to move along the height direction of the housing 10, thereby achieving the purpose of adjusting the installation position. With the above technical solution, when the pulley needs to be installed on different types of profiles, the first adjustment assembly 30 drives the connector 40 to move along the height direction of the housing 10 to achieve the adjustment of the position of the connector 40, thereby facilitating the installation of the connector 40 on profiles with different position and spatial dimensions, thereby improving the adaptability of the overall pulley.

[0042] Specifically, see Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 The first adjustment assembly 30 includes a fixing base 301, a first adjustment screw 302, and a fixing block 303. The fixing base 301 is mounted on the housing 10 and is hollow with openings on both sides. The first adjustment screw 302 extends vertically through the bottom surface of the fixing base 301. One end of the fixing block 303 is located inside the fixing base 301 and is threadedly connected to the first adjustment screw 302. The other end of the fixing block 303 is located outside the fixing base 301. The connector 40 is mounted on the end of the fixing block 303 located outside the fixing base 301. When the installation position does not match the profile, rotating the first adjustment screw 302 causes the fixing block 303 to move along the axial direction of the first adjustment screw 302, thereby moving the connector 40 and adjusting the installation position to accommodate profiles of different sizes.

[0043] Furthermore, a slide groove 101 is provided on both sides of the shell 10, and the extension direction of the slide groove 101 is parallel to the height direction of the shell 10. The fixed seat 301 is arranged in the slide groove 101, and the fixed seat 301 can slide along the slide groove 101 to adjust the position of the first adjustment component 30.

[0044] See also Figure 5 and Figure 6 A first threaded hole 3031 is provided at one end of the fixing block 303 located inside the fixing seat 301. The first threaded hole 3031 is threadedly connected to the first adjusting screw 302. Therefore, rotating the first adjusting screw 302 can drive the fixing block 303 to move along the first adjusting screw 302.

[0045] Furthermore, a first through-hole 3032 is defined at one end of the fixing block 303 located outside the fixing base 301, a second through-hole 3011 is defined on the bottom surface of the fixing base 301, and a third through-hole 3012 is defined on the top surface of the fixing base 301. During installation, the end of the fixing block 303 with the first threaded hole 3031 is placed within the fixing base 301. The first adjustment screw 302 is then passed vertically through the second through-hole 3011, the first threaded hole 3031, and the third through-hole 3012, extending from the top surface of the fixing base 301. The first adjustment screw 302 is then rotated to adjust the position of the fixing block 303. Finally, the connector 40 is passed through the first through-hole 3032 and connected to the profile, thereby mounting the pulley to the bottom surface of the profile.

[0046] Because the second through hole 3011 and the third through hole 3012 are not threaded, there is a chance that the first adjusting screw 302 will fall out. In some embodiments, to prevent the first adjusting screw 302 from falling out, the first adjusting assembly 30 further includes a U-shaped retaining spring 304. A first retaining groove 3021 is circumferentially disposed on the end of the first adjusting screw 302 facing the second through hole 3011. When the first adjusting screw 302 passes through the second through hole 3011 and the third through hole 3012, the U-shaped retaining spring 304 engages with the first retaining groove 3021. Simultaneously, the U-shaped retaining spring 304 abuts against the inner bottom surface of the fixing base 301, thereby preventing the first adjusting screw 302 from slipping out of the second through hole 3011 and thereby securing the first adjusting screw 302.

[0047] In some embodiments, the pulley with adjustable installation position of the present invention also includes a second adjustment component 50 arranged on the outer shell 10, and the second adjustment component 50 is connected to the pulley assembly 20, which is used to adjust the position of the pulley assembly 20 along the height direction of the outer shell 10; secondary adjustment is achieved to further adapt to profiles of different sizes and installation positions, thereby improving the adaptability of the pulley.

[0048] Furthermore, a first guide hole 102 is provided in the outer shell 10. The extension direction of the first guide hole 102 is arranged at an acute angle to the longitudinal direction of the outer shell 10, which can be understood as the first guide hole 102 being arranged at an angle. The pulley assembly 20 includes an inner shell 201, a sliding wheel 202, and a connecting shaft 203. The inner shell 201 is disposed within an inner cavity formed inside the outer shell 10. The sliding wheel 202 is rotatably mounted on the inner shell 201. The connecting shaft 203 is connected to the inner shell 201. The outward end of the connecting shaft 203 passes through the inner shell 201 and is inserted into the first guide hole 102. The pulley assembly 20 also includes a rotating shaft 204 disposed inside the inner shell 201. The sliding wheel 202 is rotatably connected to the rotating shaft 204. The second adjustment assembly 50 includes a second adjustment screw 501. One end of the second adjustment screw 501 extends through the outer shell 10 and is threadedly connected to the inner shell 201.

[0049] When it is necessary to adjust the height of the sliding wheel 202 relative to the outer shell 10; since the second adjusting screw 501 is threadedly connected to the inner shell 201, rotating the second adjusting screw 501 can drive the inner shell 201 to approach the second adjusting screw 501 or move away from the second adjusting screw 501; at the same time, since the connecting shaft 203 is inserted into the first guide hole 102, and the extension direction of the first guide hole 102 is set at an acute angle to the length direction of the outer shell 10, when the inner shell 201 approaches the second adjusting screw 501 or moves away from the second adjusting screw 501, the inner shell 201 will move along the first guide hole 102, and the position of the sliding wheel 202 in the height direction of the outer shell 10 will change accordingly during the movement, thereby adjusting the height of the sliding wheel 202.

[0050] Furthermore, a second guide hole 103 is provided on the outer shell 10, and the extension direction of the second guide hole 103 is parallel to the length direction of the outer shell 10, and a fourth through hole 104 is provided on the side of the outer shell 10; the pulley assembly 20 also includes a connecting block 205, an adjusting block 206 and a connecting pin 207, and a fifth through hole 2051 and a sixth through hole 2052 are provided on the connecting block 205; a convex shaft 2061 is provided at both ends of the adjusting block 206, and a second threaded hole 2062 is provided on the side of the adjusting block 206 facing the second adjusting screw 501; the connecting pin 207 passes through the fifth through hole 2051 and is connected to the inner shell 201, and the convex shaft 2061 passes through the sixth through hole 2052 and is clearance-fitted with the second guide hole 103; the second adjusting screw 501 passes through the fourth through hole 104 and is threadedly connected to the second threaded hole 2062.

[0051] When in use, by rotating the second adjusting screw 501, the second adjusting screw 501 drives the adjusting block 206 to move along the axial direction of the second adjusting screw 501, the adjusting block 206 drives the connecting block 205 to move synchronously, and the connecting block 205 drives the inner shell 201 to move synchronously. Figure 3 As shown, when the inner shell 201 moves in the direction away from the second adjusting screw 501, the inner shell 201 will drive the connecting shaft 203 to move upward along the first guide hole 102. Since the sliding wheel 202 is set on the inner shell 201, the sliding wheel 202 will move upward at this time, and vice versa.

[0052] In some embodiments, the second adjustment assembly 50 further includes a circular retaining spring 502. A second retaining groove 5011 is defined at the end of the second adjustment screw 501 facing away from the inner housing 201. When the second adjustment screw 501 passes through the fourth through hole 104, the circular retaining spring 502 engages with the second retaining groove 5011. The circular retaining spring 502 can retain the second adjustment screw 501, preventing it from rotating in place and from disengaging from the fourth through hole 104.

[0053] Next, the installation steps of the pulley with adjustable installation position involved in the present invention are described in detail; please refer to Figure 8 , the figure shows a first profile 601 and a second profile 602 arranged up and down; specifically, the pulley is mounted on the bottom surface of the first profile 601 so that the first profile 601 can slide relative to the second profile 602; Figure 9 and Figure 10 As shown, during installation, the first adjusting screw 302 is rotated to drive the fixing block 303 to move axially along the first adjusting screw 302 until the fixing block 303 abuts against the bottom surface of the connecting portion 6011 of the first profile 601. At this time, the connecting member 40 is passed through the first through hole 3032 and inserted into the connecting portion 6011 to complete the installation of the pulley.

[0054] Compared with the prior art, the pulley with adjustable installation position involved in the present invention includes a shell 10, a pulley assembly 20, a first adjustment assembly 30 and a connecting member 40; wherein the pulley assembly 20 is assembled to the shell 10, and the shell 10 is installed to the bottom of the door and window profile through the connecting member 40 to realize the pushing and pulling of the doors and windows; when the pulley needs to be installed on different types of profiles, the connecting member 40 is driven by the first adjustment assembly 30 to move along the height direction of the shell 10 to realize the adjustment of the position of the connecting member 40, thereby facilitating the installation of the connecting member 40 on profiles in different position spaces, thereby improving the adaptability of the overall pulley.

[0055] The above merely represents the preferred technical solution of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
