Detailed Implementation

[0020] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As shown in the attached figure, this utility model discloses a wheel assembly structure for side-pressure sliding doors and windows, including a fixed base 1, a sliding seat 2, a pulley assembly 3, and an adjustment structure. The sliding seat 2 is slidably connected to the fixed base 1, and the pulley assembly 3 is connected to the sliding seat 2 via the adjustment structure. The adjustment structure is used to adjust the vertical position of the pulley assembly 3 on the sliding seat 2. The pulley assembly 3 includes a lower wheel 31 for sliding linearly along a track, and a side-pressure wheel 32 perpendicular to the lower wheel 31. The lower wheel 31 is mainly used for sliding connection with the track inside the frame, while the side-pressure wheel 32... It slides against the side pressure wall of the frame during side pressure. Since the current side pressure method guides the sliding seat 2 to move laterally through the inclined groove, the lower wheel 31 can press the sliding seat 2 against the side pressure wall of the frame without leaving the track. This inclined groove guiding structure makes the lower wheel 31 still slide a certain distance along the track inside the frame during the side pressure process. In the previous structure, the sliding seat 2 and the pulley assembly 3 would rub against the side pressure wall of the frame during the sliding process. However, the side pressure wheel 32 can slide on the side pressure wall instead of the sliding seat 2, thereby preventing the sliding seat 2 and the pulley assembly 3 from rubbing against the side pressure wall.

[0022] This utility model discloses a wheel assembly structure for side-pressure sliding doors and windows. The sliding seat 2 slides on the fixed base 1, and the pulley assembly 3 is installed on the sliding seat 2 and slides with the sliding seat 2. Based on the original basic structure of the side-pressure wheel 32 sets, the pulley assembly 3 is connected to the sliding seat 2 through an adjustment structure. The adjustment structure is used to adjust the height of the pulley assembly 3 on the sliding seat 2, thereby realizing the adjustment of the height of the movable sash, which is convenient for disassembly and assembly. Before installation or disassembly, the pulley assembly 3 can be adjusted and lowered to reduce the overall height of the movable sash, which is more conducive to disassembly and assembly, and at the same time allows the sash frame to fit better.

[0023] In this embodiment, the pulley assembly 3 includes a bracket 33, a sliding rod 34 is provided in the middle of the bracket 33 and connected to the sliding seat 2 through the sliding rod 34, the lower wheel 31 is symmetrically arranged on the bracket 33 with the sliding rod 34 as the center, and the side pressure wheel 32 is rotatably arranged on the bracket 33 and located below the sliding rod 34. A pulley assembly 3 includes at least 2 lower wheels 31, and may also include 4 or more. The lower wheels 31 are rotatably connected to the bracket 33, and the bracket 33 is connected to the sliding seat 2 through the sliding rod 34, so that the bracket 33 can swing with the sliding rod 34 as the fulcrum, making it easier for the pulley assembly 3 to pass through some uneven tracks. The side pressure wheel 32 is arranged in the middle of the bracket 33 and corresponds to the sliding rod 34 vertically.

[0024] In this embodiment, the adjustment structure includes an adjustment rod 41, a slanted slot 42, and a transmission block 43. The slanted slot 42 is disposed on the sliding seat 2. Referring to the existing installation position of the side pressure roller 32 group, the side pressure roller 32 group is generally installed on both sides of the bottom of the movable fan. The end of the adjustment rod 41 away from the transmission block 43 corresponds to the side of the movable fan, and this end is provided with a tool slot for easy insertion of tools for turning. The sliding rod 34 passes through and is slidably connected to the slanted slot 42. The transmission block 43 is slidably disposed on the end of the bracket 33. The end of the sliding seat 2 has a boss 21 protruding. The adjustment rod 41 passes through the boss 21 and the transmission block 43 in sequence, and the adjustment rod 41 is rotatably connected to the boss 21. The transmission block 43 has a threaded hole 430 for threaded connection to the adjustment rod 41. The pulley assembly 3 can be adjusted in height on the sliding seat 2 through this adjustment structure. Specifically, the boss 21 has a passage for the adjustment rod 41 to pass through. The through hole 210 has an annular groove 2100 on its outer side. The adjusting rod 41 has a convex ring 411 corresponding to the annular groove 2100 on its outer side. The boss 21 is a split structure, including a bottom and an upper part. The bottom and upper parts have arc-shaped grooves on their facing sides. The two parts are combined to form the annular groove 2100. The bottom and upper parts are connected by screws or other tools. During installation, the convex ring 411 of the adjusting rod 41 can be placed into the arc-shaped groove at the bottom first, and then the upper part can be covered and fixedly connected, so that the adjusting rod 41 cannot be separated from the boss 21 and the adjusting rod 41 can rotate on the boss 21. The bracket 33 has a vertically arranged strip groove 330 at its end. The transmission block 43 has pins 431 that are slidably connected to the strip groove 330 at both ends. The transmission block 43 can slide up and down on the bracket 33 and is connected to the sliding rod 34 in conjunction with the inclined slot hole 42, so that the pulley assembly 3 can be adjusted up and down on the sliding seat 2 more smoothly.

[0025] In this embodiment, the fixed base 1 is provided with a groove 100, and a guide strip is provided at the bottom of the groove 100. A retaining edge 101 is provided on one side of the groove 100, and a limiting pressure plate 102 is connected to the other side by rivets. The bottom of the sliding seat 2 is provided with a sliding groove 211, and two ends of the sliding seat 2 are correspondingly provided with insert plates 212. One insert plate 212 is inserted between the retaining edge 101 and the bottom of the groove 100, and the other insert plate 212 is inserted between the limiting pressure plate 102 and the bottom of the groove 100. This structure provides a connection structure between the sliding seat 2 and the fixed base 1. Specifically, the retaining edge 101... 01 is set on one side of the groove 100, and there is space between the sidewall 101 and the bottom of the groove for the insertion plate 212 to be inserted. During installation, the sliding seat 2 is tilted so that the insertion plate 212 on one side is inserted into the space between the sidewall 101 and the bottom of the groove. After the sliding groove 211 cooperates with the guide bar and the sliding seat 2 is placed into the groove 100 of the fixed base 1, the limiting pressure plate 102 is placed on the other side of the insertion plate 212, and the limiting pressure plate 102 and the fixed base 1 are fixedly connected by rivets or other connecting parts, thereby realizing the installation of the sliding seat 2 on the fixed base 1 and ensuring that the sliding seat 2 can slide along the guide bar.

[0026] It also includes a transmission structure with a side pressure groove. The sliding seat 2 has a pull pin 2001 that is connected to the side pressure groove on the side facing the fixed base 1. The fixed base 1 has a clearance channel 1000 for the pull pin 2001 to move. The pull pin 2001 protrudes from one side of the fixed base 1 and slides with the sliding seat 2. Therefore, the fixed base 1 has a clearance channel 1000 for the pull pin 2001 to protrude and slide. Specifically, the transmission structure includes a transmission box, a transmission rod, etc. The transmission rod is provided with a side pressure groove, which is used to cooperate with the pull pin 2001.
