Detailed Embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] As shown in the attached drawings, a structure of an anti-sway wheel of the present utility model includes a door frame 5 and a door body 6. If it is used on a window, it corresponds to a window frame and a window body. A track groove 50 is provided inside the door frame 5. Specifically, the profile of the door frame 5 is provided with the track groove 50, which belongs to an existing structure and will not be described in detail. Specifically, it further includes a wheel body seat 1. A pulley 2 matching the width of the track groove 50 is rotatably provided in the middle of the wheel body seat 1. The pulley is detachably connected to the wheel body seat 1. Specifically, the diameter of the pulley 2 corresponds to the width of the track groove 50. Even after the anti-sway wheel is placed in the track, the pulley 2 abuts against both sides of the track, ensuring that the linear sliding of the anti-sway wheel in the track will not deviate. The pulley 2 and the wheel body seat 1 are detachably connected. By replacing the pulley 2 with a corresponding size according to different track widths, the anti-sway wheel can be adjusted. Connection blocks 3 are provided at both ends of the wheel body seat 1. A T-shaped groove 30 is provided at the bottom of the connection block 3, and the connection block 3 is connected to the door body 6 through the T-shaped groove 30.

[0021] A structure of an anti-sway wheel of the present utility model provides another anti-sway positioning structure for doors and windows through the wheel body seat 1. The wheel body seat 1 is composed of a pulley 2 and a connection block 3. By installing a pulley 2 matching the width of the track groove 50, there is no need to adjust the pulley 2. Only by replacing the pulley 2 matching the width of the track groove 50 can the adjustment be completed at one time. Moreover, the overall structure of the anti-sway wheel is simplified, which is more conducive to production and practical application. The connection block 3 is connected to the door body 6 and hung on the door frame 5, realizing the connection between the wheel body seat 1, the door body 6, and the door frame 5.

[0022] In this embodiment, a T-shaped groove 30 is provided at the bottom of the connection block 3. A T-shaped hanging rib 33 fixedly connected to the door body 6 is inserted into the T-shaped groove 30. The T-shaped hanging rib 33 fixedly connected to the door body 6 is inserted into the T-shaped groove 30 to prevent the wheel body seat 1 from detaching from the door body 6. Specifically, the shape of the T-shaped groove 30 is as Figure 1 shown, and its cross-section is a T-shape with a wider top and a narrower bottom. The cross-section of the T-shaped hanging rib 33 is the same. Therefore, when the T-shaped hanging rib 33 penetrates into the T-shaped groove 30, the T-shaped hanging rib 33 cannot detach from the bottom slot opening. On this basis, a fixing screw 300 is provided between the T-shaped groove 30 and the T-shaped hanging rib 33. The fixing screw 300 is used to expand the T-shaped hanging rib 33 and the connection block 3, so that the T-shaped hanging rib 33 tightly abuts against the inner wall of the T-shaped groove 30, thereby fixedly connecting the connection block 3 and the T-shaped hanging rib 33 to prevent detachment, as Figure 1 shown in or 6. Preferably, an arc concave surface is provided on the T-shaped hanging rib 33 and the T-shaped groove 30, which is more conducive to the entry of the fixing screw 300.

[0023] In this embodiment, anti - detachment plates 501 protruding towards the track groove 50 are provided on both sides of the bottom of the door frame 5. Anti - detachment ribs 31 are symmetrically arranged on both sides of the connecting block 3. The anti - detachment ribs 31 are abutted against the upper sides of the corresponding anti - detachment plates 501, that is, the anti - detachment ribs 31 are arranged on the outer side surfaces of the two groove walls of the T - shaped groove 30. The distance between the two anti - detachment plates 501 is less than the distance between the two anti - detachment ribs 31, so as to prevent the connecting block 3 from falling out between the two anti - detachment plates 501, ensuring that the connecting block 3 can be stably suspended in the door frame 5, and realizing the connection of the connecting block 3 to the door body 6 and the door frame 5 respectively.

[0024] In this embodiment, the setting height of the lower surface of the pulley 2 is higher than the setting height of the lower surface of the anti - detachment rib 31. Since the main function of the anti - swing wheel structure is to prevent the door body 6 from swinging, the anti - detachment rib 31 does not need to bear the load - bearing function. Its main function is to ensure that the connecting block 3 cannot fall out of the door frame 5. In practical applications, the anti - detachment rib 31 can be set higher than the anti - detachment plate 501 or in contact with the anti - detachment plate 501. The height settings of the pulley 2, the anti - detachment rib 31 and the T - shaped groove 30 are mainly for adapting to the door frame 5. Therefore, their heights can be set by themselves without affecting the normal use of the anti - swing wheel.

[0025] In this embodiment, a buffer block 40 for cooperating with the buffer 505 is prominently provided in the middle of the wheel body base 1. The pulley 2 is arranged at the bottom of the buffer block 40, and the connecting block 3 is arranged at both ends of the buffer block 40. It should be noted that the buffer 505 is one of the accessories on the existing sliding doors and windows. It can slow down the impact force, reduce noise and protect the door body 6, etc. Generally, the buffer 505 needs to install an intervening body on the door body 6 to cooperate with it. When the door body 6 is closed, the intervening body needs to be stuck into the movable block 505a of the buffer 505. By providing the buffer block 40, the installation of the intervening body can be avoided, saving the installation of redundant accessories on the door body 6. The buffer block 40 is provided with an installation hole 400. The pulley 2 is rotatably provided with a connecting rod 22 connected to the installation hole 400. The installation hole 400 and the connecting rod 22 can refer to the existing connection structure, such as using a threaded connection. External threads are provided on the outer side of the connecting rod 22, and internal threads are provided on the inner side of the installation hole 400. The pulley 2 is installed by directly screwing in the connecting rod 22. One end of the connecting rod 22 is provided with a head, and a hole is provided on the central axis of the pulley 2 for the connecting rod 22 to pass through. Further, the head of the connecting rod 22 can be set as a screwing part that is convenient for people to hold and turn. The wheel body base 1 is an integrally formed structure, which is more conducive to the production of the wheel body base 1. The specific structure refers to Figure 1 , the middle of the wheel body base 1 is the buffer block 40, and both ends are the connecting blocks 3. The buffer block 40 and the connecting blocks 3 are integrally formed. The buffer block 40 is provided with an installation hole 400 and is detachably connected to the pulley 2 through the installation hole 400.

[0026] The above embodiments are the preferred embodiments of the present utility model. Any structure similar to the present utility model and equivalent changes made thereto shall fall within the protection scope of the present utility model.
