[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] The directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "inner," "outer," and "side," are merely for reference to the accompanying drawings. Therefore, the directional terms used are for explanation and understanding of this invention, and not for limiting it. Furthermore, in the accompanying drawings, structures that are similar or identical are indicated by the same reference numerals.

[0034] Reference Figures 1 to 11 For details, please refer to Figures 1 to 4This invention demonstrates an embodiment of the anti-sway wheel 10 provided by this utility model. The structure and working principle of the anti-sway wheel 10 will be described in detail below with reference to the accompanying drawings. The anti-sway wheel 10 is used to be installed on the frame 100 of a fan-shaped profile. The anti-sway wheel 10 includes: a slotted member 1 for fixing to the frame 100 of the fan-shaped profile, the slotted member 1 having a guide groove 101 extending at least partially along the height direction; a pulley assembly 2 including a roller 21 and a fixed bracket 22, the fixed bracket 22 being slidably connected to the guide groove 101, and the roller 21 being rotatably connected to the fixed bracket 22; and an adjusting assembly 3 disposed on the slotted member 1 and elastically connected to the fixed bracket 22, the adjusting assembly 3 cooperating with the slotted member 1 to rotate and drive the fixed bracket 22 to slide along the guide groove 101, causing the fixed bracket 22 to drive the roller 21 to rise or fall.

[0035] In practical implementation, the anti-sway wheel 10 is mainly used in sliding doors or sliding windows. Sliding doors and sliding windows are usually composed of two parts: sash profile and frame profile. The frame profile is a rectangular frame structure with tracks on the top and bottom sides, such as sliding door frames and sliding window frames. The sash profile is usually composed of a rectangular frame and glass or other profiles installed on the inside of the frame, such as sliding door sash and sliding window sash. The sash profile has pulleys installed on the bottom side or top and bottom sides of the frame. The sliding is achieved by the pulleys cooperating with the tracks of the frame profile.

[0036] In this embodiment, as Figure 11As shown, the anti-sway wheel 10 is used to install onto the frame 100 of the fan profile, typically on the upper frame. The anti-sway wheel 10 contacts and engages with the frame profile by being installed on the frame 100, reducing the fan profile's sway relative to the frame profile and improving its stability within the frame profile. The anti-sway wheel 10 consists of a slotted component 1, a pulley assembly 2, and an adjusting assembly 3. The slotted component 1 is used to connect and fix to the frame 100 of the fan profile. Specifically, the slotted component 1 can be threaded to the bottom of the fan profile frame 100 using screws. By fixing the slotted component 1 to the frame 100 of the fan profile, the entire anti-sway wheel 10 is installed onto the fan profile. The slotted component 1 is provided with a guide groove 101 extending at least partially along the height direction. The guide groove 101 is a groove structure with one part extending laterally and the other part extending upwards along the height direction. The portion between the two ends of the guide groove 101 has an arc-shaped bend transition. The guide groove 101 is mainly used to install the pulley assembly 2. The pulley assembly 2 mainly consists of a roller 21 and a fixed bracket 22. The fixed bracket 22 is slidably connected to the guide groove 101 on the through-groove 1, meaning the fixed bracket 22 can slide along the guide groove 101. The roller 21 is rotatably mounted on the fixed bracket 22. Overall, the fixed bracket 22 is slidable relative to the through-groove 1, and the roller 21 is rotatable relative to the fixed bracket 22. The sliding of the fixed bracket 22 can drive the roller 21 to move. The adjusting assembly 3 is mainly set on the through-groove 1 and is elastically connected to the fixed bracket 22. The adjusting component 3 rotates in cooperation with the slotted part 1, causing the fixed bracket 22 to slide along the guide groove 101 on the slotted part 1. Since the roller 21 is integrally connected to the fixed bracket 22, the sliding of the fixed bracket 22 along the guide groove 101 causes the roller 21 to shift relative to the slotted part 1. Specifically, the position of the fixed bracket 22 relative to the guide groove 101 determines the position of the roller 21. When the fixed bracket 22 slides to the bottom of the guide groove 101, the height of the roller 21 is the lowest; when the fixed bracket 22 slides to the top of the guide groove 101, the height of the roller 21 is the highest. By adjusting the sliding position of the fixed bracket 22 relative to the guide groove 101 through the adjusting component 3, the roller 21 can be raised or lowered. When the position of the roller 21 is fixed, the adjusting component 3 can provide elastic support when the roller 21 is under force. In practical applications, the height of the roller 21 relative to the frame 100 of the fan profile can be adjusted by rotating the adjusting component 3 to achieve the best matching effect with the frame profile and provide anti-sway function for the fan profile.

[0037] In one embodiment, reference is made to Figures 1 to 4The slotted component 1 includes a first mounting plate 11 and a second mounting plate 12 arranged in parallel and at intervals. The guide grooves 101 are respectively disposed on the first mounting plate 11 and the second mounting plate 12, and the guide grooves 101 on the first mounting plate 11 and the second mounting plate 12 overlap and are aligned. The fixed bracket 22 is disposed between the first mounting plate 11 and the second mounting plate 12, and its two sides are slidably connected to the guide grooves 101 on the first mounting plate 11 and the second mounting plate 12, respectively. The adjusting component 3 is disposed between the first mounting plate 11 and the second mounting plate 12. In specific implementation, the through-groove component 1 mainly consists of a first mounting plate 11 and a second mounting plate 12. The first mounting plate 11 and the second mounting plate 12 are arranged parallel and spaced apart. Guide grooves 101 are respectively provided on the first mounting plate 11 and the second mounting plate 12, that is, each of the first mounting plate 11 and the second mounting plate 12 has a guide groove 101. The guide groove 101 on the first mounting plate 11 coincides and is aligned with the guide groove 101 on the second mounting plate 12. The fixed bracket 22 is disposed between the first mounting plate 11 and the second mounting plate 12, and the opposite sides of the fixed bracket 22 are slidably connected to the guide grooves 101 on the first mounting plate 11 and the second mounting plate 12, respectively. The fixed bracket 22 as a whole is slidable relative to the two guide grooves 101 on the first mounting plate 11 and the second mounting plate 12. The adjusting component 3 is disposed between the first mounting plate 11 and the second mounting plate 12 and is elastically connected to the fixed bracket 22 between the first mounting plate 11 and the second mounting plate 12. Overall, the fixed bracket 22 is slidably connected to the two guide grooves 101 on the first mounting plate 11 and the second mounting plate 12 on both sides, which improves the force distribution and enhances the stability of the sliding of the fixed bracket 22.

[0038] Furthermore, referring to Figure 5 and Figure 6The fixed bracket 22 has at least one protruding shaft 221, which passes through the guide groove 101 and can slide along the guide groove 101. In a specific implementation, the fixed bracket 22 has at least one protruding shaft 221, which is a cylindrical structure and can be a rivet structure. The protruding shaft 221 on the fixed bracket 22 passes through the guide groove 101 on the slotted member 1 and can slide along the guide groove 101. The fixed bracket 22 is slidably connected to the guide groove 101 on the slotted member 1 through the protruding shaft 221. Specifically, the protruding shafts 221 are arranged on both sides of the fixed bracket 22 facing the first mounting plate 11 and the second mounting plate 12. Each side of the fixed bracket 22 is provided with two mutually spaced protruding shafts 221. The protruding shafts 221 on both sides of the fixed bracket 22 are respectively inserted into the guide grooves 101 on the first mounting plate 11 and the second mounting plate 12. The protruding shafts 221 can slide along the guide grooves 101. The fixed bracket 22 is slidably connected to the guide grooves 101 on the first mounting plate 11 and the second mounting plate 12 through the protruding shafts 221 on both sides. In practical applications, the raised shafts 221 on both sides of the fixed bracket 22 slide synchronously along the guide groove 101, causing the fixed bracket 22 to rise and fall relative to the through-groove part 1, thereby realizing the rise and fall of the roller 21. When the raised shaft 221 is at the bottom of the guide groove 101, the height of the roller 21 is at its lowest, and when the raised shaft 221 is at the top of the guide groove 101, the height of the roller 21 is at its highest. Since the fixed bracket 22 slides through the raised shafts 221 and the guide groove 101, the fixed bracket 22 has better pressure bearing capacity and improved sliding stability.

[0039] In one embodiment, reference is made to Figure 2 and Figure 7The adjusting assembly 3 includes a bolt 31, a nut 32, and a spring 33. The bolt 31 is laterally and rotatably disposed between the first mounting plate 11 and the second mounting plate 12. The nut 32 is threaded onto the bolt 31. The spring 33 is sleeved on the bolt 31, with one end abutting against the nut 32 and the other end abutting against the fixed bracket 22. The bolt 31 is used to rotate and drive the nut 32 to move along the axial direction of the bolt 31 to push the spring 33 against the fixed bracket 22. In specific implementation, the adjustment component 3 mainly consists of a bolt 31, a nut plate 32, and a spring 33. The bolt 31 is horizontally and rotatably disposed between the first mounting plate 11 and the second mounting plate 12. The nut plate 32 is threadedly connected to the bolt 31 through a threaded hole. Specifically, the nut plate 32 is located near the end of the bolt 31. The spring 33 is sleeved on the bolt 31. One end of the spring 33 abuts against the nut plate 32, and the other end of the spring 33 abuts against the fixed bracket 22. The spring 33 is located between the nut plate 32 and the fixed bracket 22. In practical applications, by rotating the bolt 31 in different directions, the nut plate 32 can move along the axial direction of the bolt 31 under the action of thread transmission. The nut plate 32 pushes the spring 33 toward the fixed bracket 22, which can compress the spring 33. When the roller 21 is not under force, the spring 33 will push the fixed bracket 22 to slide along the guide groove 101, thereby driving the roller 21 to rise and fall. When the roller 21 is under force, for example, when the roller 21 abuts against the track of the frame profile, continue to rotate the bolt 31 or press down the roller 21. The nut plate 32 will compress the spring 33, and the spring 33 will generate elastic force, so that the roller 21 will have the effect of rebounding under force, thereby providing elastic support and effectively preventing the fan profile from sliding or swaying when subjected to external force.

[0040] Furthermore, referring to Figure 5 and Figure 6The fixed bracket 22 has a vertically extending strip-shaped opening 201 on the side facing the spring 33. The end of the bolt 31 away from the nut 32 is inserted into the strip-shaped opening 201, and the end of the spring 33 abuts against the edge of the strip-shaped opening 201. In a specific implementation, a vertically extending strip-shaped opening 201 is provided on the side of the fixed bracket 22 facing the spring 33. One end of the strip-shaped opening 201 is at the top and the other end is at the bottom. The width between the left and right sides of the strip-shaped opening 201 is greater than the diameter of the bolt 31. The end of the bolt 31 away from the nut 32 is inserted into the strip-shaped opening 201. After the bolt 31 is inserted into the strip-shaped opening 201, there is still a certain gap between the upper or lower end of the strip-shaped opening 201 and the bolt 31, so that the fixed bracket 22 can move relative to the bolt 31. The diameter of the end of the spring 33 is larger than the width between the left and right sides of the strip opening 201. The end of the spring 33 abuts against the edge of the strip opening 201 without passing through the strip opening 201. The end of the bolt 31 passes through the strip opening 201, which can prevent the spring 33 from falling off the bolt 31 when the fixed bracket 22 slides, thus improving the stability of the structure.

[0041] Furthermore, referring to Figure 2 and Figure 7 The adjusting assembly 3 further includes an annular washer 34. The end of the bolt 31 away from the nut 32 passes through the annular washer 34 and is inserted into the strip opening 201. The end of the spring 33 abuts against the annular washer 34. In a specific implementation, the adjusting assembly 3 is also composed of an annular washer 34. The annular washer 34 is a thin, circular sheet. The outer diameter of the annular washer 34 is larger than the width between the left and right sides of the strip opening 201. The annular washer 34 is mainly used to make the force on the spring 33 more even. The end of the bolt 31 away from the nut 32 passes through the annular washer 34 and is inserted into the strip opening 201, while the spring 33 is located between the nut 32 and the annular washer 34. The end of the spring 33 away from the nut 32 abuts against the annular washer 34. Through the annular washer 34, the force on the spring 33 can be made more even.

[0042] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 8The slotted component 1 further includes a mounting base 13, which is connected to one end of both the first mounting plate 11 and the second mounting plate 12. The mounting base 13 has a groove 102 and a notch 103 formed on it. The groove 102 extends directly between the first mounting plate 11 and the second mounting plate 12 through the notch 103. The bolt 31 passes through the notch 103, with one part located within the groove 102 and the other part located between the first mounting plate 11 and the second mounting plate 12. The portion of the bolt 31 located within the groove 102 stops at one end of the notch 103, and the nut piece 32 stops at the other end of the notch 103. In a specific implementation, the slotted component 1 further includes a mounting base 13, which is connected to one end of both the first mounting plate 11 and the second mounting plate 12. The mounting base 13 is mainly used to connect the bolt 31 so that it can rotate independently. Specifically, the mounting base 13 has adjacent grooves 102 and notches 103. The groove 102 extends directly between the first mounting plate 11 and the second mounting plate 12 through the notch 103. The bolt 31 passes entirely through the notch 103 and can rotate freely relative to it. Part of the bolt 31 is located within the groove 102, and the other part is located between the first mounting plate 11 and the second mounting plate 12. The portion of the bolt 31 within the groove 102 is stopped at one end of the notch 103, while the nut 32 is stopped at the other end of the notch 103. The nut 32 is entirely located between the first mounting plate 11 and the second mounting plate 12. When the bolt 31 is rotated, it is blocked by one end of the notch 103 and restricted by the groove 102, causing it to rotate in place. The nut 32 moves along the axial direction of the bolt 31 between the first mounting plate 11 and the second mounting plate 12, pushing the spring 33.

[0043] Furthermore, referring to Figure 9The bolt 31 includes a head 311 and a threaded portion 312 connected to each other. The head 311 is received within the groove 102 and stopped at one end of the notch 103. The threaded portion 312 is laterally disposed between the first mounting plate 11 and the second mounting plate 12. The nut 32 is threadedly connected to the threaded portion 312. In a specific implementation, the bolt 31 consists of a head 311 and a threaded portion 312. The head 311 is connected to one end of the threaded portion 312, which has a threaded post structure. The diameter of the head 311 of the bolt 31 is larger than the diameter of the threaded portion 312. The head 311 of the bolt 31 is received within the groove 102 on the mounting base 13 and stopped at one end of the notch 103, preventing the head 311 from passing through the notch 103. The threaded portion 312 of the bolt 31 passes through the notch 103 and is laterally disposed between the first mounting plate 11 and the second mounting plate 12. The nut 32 is threadedly connected to the threaded portion 312 through a threaded hole. When the bolt 31 is rotated, the head 311 of the bolt 31 rotates in the groove 102, and the threaded part 312 of the bolt 31 drives the nut to move, thereby pushing the spring 33.

[0044] Furthermore, referring to Figure 10 An adjustment portion 301 is provided on the side of the head 311 away from the threaded portion 312. An adjustment hole 104 with a diameter smaller than that of the head 311 is provided on the mounting base 13. The groove 102 extends directly through the adjustment hole 104 to the outside of the mounting base 13. The adjustment portion 301 is exposed on the outside of the mounting base 13 through the adjustment hole 104. The adjustment portion 301 is used to rotate the bolt 31 with a tool. In a specific embodiment, the adjustment portion 301 is provided on the side of the bolt 311 away from the threaded portion 312. The adjustment portion 301 is a structure used to rotate the bolt 31 with a tool. In this embodiment, the adjustment portion 301 has an internal hexagonal opening. In other embodiments, the adjustment portion 301 can be a slotted opening, a cross opening, or other structures. An adjustment hole 104 is provided on the mounting base 13. The diameter of the adjustment hole 104 is smaller than the diameter of the head 311 of the bolt 31. The groove 102 extends directly through the adjustment hole 104 to the outside of the mounting base 13. The adjustment part 301 provided on the head 311 of the bolt 31 is exposed on the outside of the mounting base 13 through the adjustment hole 104. In practical applications, tools such as an Allen wrench or screwdriver are used to engage with the adjustment part 301 through the adjustment hole 104, thereby allowing the head 311 of the bolt 31 to be rotated very easily to adjust the height of the roller 21.
