[0002] Sliding doors and windows are common building doors, which are pushed / pulled by pulleys. In the past, the pulleys of sliding doors and windows were installed at the bottom of the glass leaf and slidably connected to the track in the frame to achieve pushing and pulling. In order to facilitate the protection and replacement of the pulleys, some sliding doors and windows arrange the pulleys in the frame, and set the guide strips that match the pulleys at the bottom of the glass leaf. Such a structure is also called a frame-mounted wheel set, which is particularly suitable for larger sliding doors and windows. In the existing frame-mounted wheel set structure, multiple U-shaped grooves of the same depth are opened on the bottom frame profile, and the rotating shaft is set in the corresponding U-shaped grooves. The pulley set is mainly installed on the frame by opening U-shaped grooves of the same depth. At the same height, however, affected by the processing accuracy of the current profiles and pulley blocks, the horizontality of the outer frame installation, installation errors, etc., there will be a certain height difference between the pulley blocks. The glass sash is placed on the pulley blocks, and it is difficult to ensure that the pulley blocks covering the bottom of the glass sash can support the glass sash. Some pulley blocks installed lower may not be able to contact the glass sash, and the glass sash does not move smoothly on the uneven pulley blocks, causing the glass sash to get stuck when sliding on it, colliding with the pulleys, etc. At the same time, the existing pulleys are directly installed in the frame through the rotating shaft, and the position of each pulley cannot be adjusted. Therefore, this problem has not been effectively solved. Utility Model Content

The first adjusting block 31 and the second adjusting block 32 slide relatively forward and backward through the screwing of the adjusting screw 33. The adjusting member 3 is placed in the bottom frame profile 1, and the rotating shaft 21 is horizontally placed between the first adjusting block 31 and the second adjusting block 32.
[0021] The utility model discloses a frame-mounted wheel group with adjustable height. The height of the pulley group 2 is adjusted by the arranged adjusting member 3. The adjusting member 3 corresponds to the pulley group 2, that is, the height of each pulley group 2 can be adjusted separately, so that each pulley group 2 is arranged on the same horizontal plane, and unevenness between the pulley groups 2 is prevented, so as to better support the glass fan and ensure the normal sliding use of the glass fan.
[0022] refer to Figure 3-4 The second adjustment block 32 is protrudingly provided with a baffle 321, and a channel is formed between the two baffles 321. The first adjustment block 31 is arranged between the two baffles 321. The first adjustment block 31 and the baffle 321 face each other on an inclined surface, and the two inclined surfaces intersect to form an opening 301 with a V-shaped cross section. It should be noted that the baffle 321 is as shown in FIG. Figure 4As shown in the figure, two blocks are provided, and the sides of the two baffles 321 facing the first adjustment block 31 are both set as inclined surfaces 300. The rotating shaft 21 is arranged on the opening 301 and abuts against the inclined surface 300. The outer curved surface of the rotating shaft 21 is tangent to the inclined surface 300. The rotating shaft 21 is lifted and lowered by the relative forward and backward sliding of the first adjustment block 31. The second adjustment block 32 and the two protruding baffles 321 are combined with each other to form a recess. The first adjustment block 31 is arranged in the recess. A groove is arranged on the top of the first adjustment block 31. The inclined surface 300 located on the first adjusting block 31 is a side wall of the groove, and the bottom of the groove is an arc shape matching the rotating shaft 21. The two inclined surfaces 300 of the first adjusting block 31 and the baffle 321 constitute the two side walls of the opening 301. As the adjusting screw 33 is turned, the first adjusting block 31 and the second adjusting block 32 approach or move away from each other, so that the opening 301 gradually shrinks or expands, thereby lifting or lowering the rotating shaft 21. It should be noted that the opening 301 is reduced or expanded in the same proportion, and the angle of the opening 301 is fixed.
[0023] refer to Figure 1-2 The bottom frame profile 1 is provided with frame plates 101 on the front and rear sides in the width direction, and two partitions 102 are provided in the middle. The frame plates 101 and the partitions 102 are provided with U-shaped grooves 100 for installing the pulley block 2. The frame plates 101 and the partitions 102 are provided with multiple U-shaped grooves 100 at intervals. The width of the U-shaped groove 100 corresponds to the diameter of the rotating shaft 21. The distance between the two partitions 102 corresponds to the width of the adjusting member 3. The structure of the bottom frame profile 1 including the frame plates 101 and the partitions 102 belongs to the existing structure. The existing sliding wheel 22 is placed between the frame plates 101 and the partitions 102. It should be particularly noted that according to the existing structure, the width of the adjusting member 3 is set on the two partitions 102 so that the distance between the two partitions 102 is equal to the width of the adjusting member 3, ensuring that the adjusting member 3 cannot be laterally offset, and mounting parts are also provided at both ends of the rotating shaft 21. The width of the U-shaped groove 100 is the same as the diameter of the mounting part.
[0024] refer to Figure 3-4 The adjusting screw 33 is passed through the second adjusting block 32 and is threadedly connected to the second adjusting block 32. One end of the adjusting screw 33 is rotatably connected to the first adjusting block 31, that is, one end of the adjusting screw 33 and the first adjusting block 31 form a positioning structure. The adjusting screw 33 can only rotate on the first adjusting block 31. The first adjusting block 31 and the adjusting screw 33 can be rotatably connected by rotating the bearing. The adjusting screw 33 is connected to the inner ring of the bearing, and the first adjusting block 31 is connected to the outer ring. Moreover, the width of the second adjusting block 32 corresponds to the straight-line distance between the two baffles 321. The first adjusting block 31 is arranged in the channel of the second adjusting block 32, and the width of the channel corresponds to the width of the first adjusting block 32.
[0025] Compared with the existing structure, the adjustment member 3 is added, and each pulley block 2 is equipped with the same adjustment member 3, which provides a height-adjustable function for each pulley block 2. When installing, the adjustment member 3 is first placed, and then the pulley block 2 is placed, so that the rotating shaft 21 is placed horizontally on the opening 301 and is set in the U-shaped groove 100. By turning the adjustment screw 33, the relative sliding of the first adjustment block 31 and the second adjustment block 32 is achieved, that is, they are close to or away from each other, so that the rotating shaft 21 is raised and lowered. For example, by turning the adjustment screw 33 clockwise, the first adjustment block 31 and the second adjustment block 32 are close to each other, that is, the two inclined surfaces 300 overlap. Since the inclined surface 300 has a certain slope, when the first adjustment block 31 and the second adjustment block 32 gradually approach each other, the rotating shaft 21 placed on the upper part is pushed by the two inclined surfaces 300 on both sides of the oblique lower side, and gradually rises. Figure 5 and 6 , the opening 301 gradually shrinks, so that the rotating shaft 21 abutting against the two inclined surfaces 300 gradually rises. When the rotating shaft 21 is in the rising state, it is out of contact with the lower side of the U-shaped groove and is mainly supported by the inclined surface 300. The adjusting screw 33 is reversed to make the first adjusting block 31 and the second adjusting block 32 move away from each other, that is, the intersection point of the inclined surfaces 300 gradually decreases, and the opening 301 is expanded, so that the rotating shaft 21 descends. When the rotating shaft 21 descends to the bottom, it is in contact with the bottom of the U-shaped groove 100, and the rotating shaft 21 is supported by the U-shaped groove 100 and the inclined surface 300.
