[0002] Door and window hanging wheels are an important component of sliding doors used in balconies, kitchens, dining rooms and other areas. Their main function is to lift the door leaf, bear the weight of the door, and cooperate with the hanging rails to enable the door to move easily.

[0003] The existing door and window hanging wheels can refer to the hanging door and window hanging pulley disclosed in the Chinese utility model patent with patent application number CN202320419123.3, including a hanging part, a pulley, a pre-assembled part, a screw rod and a connecting part, wherein a plurality of pulleys are installed on the hanging part, a slot is provided on the hanging part, and a fixed platform is provided in the slot. The pre-assembled part can be inserted in the slot, and a screw hole and a clamping platform are provided on the pre-assembled part, and the clamping platform can cooperate with the fixed platform. A screw rod is installed on the connecting part, one end of the screw rod is connected to the connecting part, and the other end of the screw rod can be inserted in the screw hole. In the actual operation process, the structure pre-assembles the pre-assembled part on the screw rod, and then can be quickly inserted into the slot, which can reduce the installation difficulty of the hanging doors and windows and reduce the manpower consumption during the installation process, thereby improving the installation efficiency of the hanging doors and windows.

[0004] However, in the above structure, after the connecting piece is fixed on the door and window, since the length of the screw is fixed, if you want to adjust the installation height of the door and window at this time, you need to disassemble the connecting piece again, replace the screw with a different length and then reinstall it. This will not only waste a lot of installation time, but repeated disassembly may also cause damage to the door and window structure. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, but the utility model is not limited to the following embodiments.

[0024] like Figures 1 to 5As shown, the present embodiment discloses an automatic anti-loosening hanging wheel hanging box with adjustable height, comprising a connecting seat 1 for fixing on doors and windows, an adjusting bolt 2 rotatably mounted on the connecting seat 1, and an adjusting component 3 movably mounted inside the connecting seat 1, wherein an installation cavity 10 for installing the adjusting component 3 is provided in the connecting seat 1 along the length direction, one end of the installation cavity 10 is open, and the other end is closed, a rotating hole for installing the adjusting bolt 2 is provided on the top of the connecting seat 1 near the closed end of the installation cavity 10, the lower end of the adjusting bolt 2 extends from the rotating hole into the installation cavity 10 and is engaged with the adjusting component 3, the upper end of the adjusting bolt 2 extends upward and is threadedly connected to the hanging wheel, and the hanging wheel is a conventional component, so it is not described in detail; the adjusting component 3 comprises a compression spring 31, a first limiting rod 32, a second limiting rod 33 and The adjusting rod 34, the first limiting rod 32, the second limiting rod 33 and the adjusting rod 34 are rigidly connected, one end of the compression spring 31 abuts against the closed end of the installation cavity 10, and the other end of the compression spring 31 abuts against the first limiting rod 32 so that the first limiting rod 32 and the second limiting rod 33 are snap-fitted to the adjusting bolt 2. When you want to adjust the installation height of the doors and windows, you can push the adjusting rod 34 inward to move the first limiting rod 32 inward to compress the compression spring 31 until the first limiting rod 32 is out of cooperation with the adjusting bolt 2. At this time, you can rotate the adjusting rod 34 to make the second limiting rod 33 drive the adjusting bolt 2 to rotate. By rotating the adjusting bolt 2, the tightening distance between the adjusting bolt 2 and the hanging wheel is changed to adjust the installation height of the doors and windows. In this way, you can adapt and adjust after the doors and windows are installed without multiple disassembly, and the adjustment is simpler and more convenient.

[0025] In this embodiment, a driving portion 21 for conveniently driving the rotation is provided on one end of the adjusting bolt 2 extending into the installation cavity 10, and a driving tooth 22 is provided on the driving portion 21. The first limiting rod 32 and the second limiting rod 33 are provided with a segment tooth structure 300 for meshingly connecting to the driving portion 21, and the segment tooth structure 300 extends a certain distance along the length direction of the first limiting rod 32 and the second limiting rod 33.

[0026] Furthermore, in order to allow the first limiting rod 32 to smoothly detach from the connection with the driving part 21 after the adjusting rod 34 is pushed inward, a gap is provided between the first limiting rod 32 and the second limiting rod 33. Specifically, a connecting rod 35 is provided between the first limiting rod 32 and the second limiting rod 33, and the diameter of the connecting rod 35 is smaller than the diameter of the first limiting rod 32 and the second limiting rod 33 to form a gap.

[0027] Preferably, the second limiting rod 33 is disposed at the inner end of the adjusting rod 34 and is integrally formed with the adjusting rod 34. Specifically, for easy installation, the adjusting rod 34, the connecting rod 35, and the second limiting rod 33 can be integrally formed or threadedly connected in sequence.

[0028] In this embodiment, a limit opening 340 is provided in the middle portion of the adjusting rod 34 for limiting the inward and outward movement distance of the adjusting rod 34, and a limit structure is provided inside the connecting seat 1 for cooperating in the limit opening 340. The limit structure is pressed against the limit opening 340 to avoid excessive movement of the adjusting rod 34, thereby improving the stability of the adjusting component 3.

[0029] In this embodiment, in order to prevent the adjusting rod 34 from being easily disturbed by the outside world after protruding from the connecting seat 1, the outer end of the adjusting rod 34 needs to be retracted into the mounting cavity 10. In order to facilitate adjustment, an adjusting groove 341 is extended axially inward on the outer end surface of the adjusting rod 34. The cross-section of the adjusting groove 341 can be a hexagonal socket or other shapes. The adjusting rod 34 can be pushed and rotated inward by using a hexagonal socket wrench or other shaped tools.
