Description

Technical Field

[0001] The utility model belongs to the field of sliding parts of sliding doors, and particularly relates to a hanging wheel structure capable of adjusting the height of a door body. Background Art

[0002] The hanging wheels of existing hanging doors are installed on the door body through hanging boxes. In order to adjust the distance between the profile for installing the hanging wheels and the door body, a lifting and adjusting structure of the hanging wheels is usually provided. The existing lifting and adjusting structure uses a lifting block and a hanging box which are detachably connected, and drives the hanging box and the door body to realize the lifting and adjusting function through the vertical movement of the lifting block. Since the lifting block and the hanging box are separately arranged, the overall weight is increased, and at the same time, a large driving force is required for the vertical movement of the lifting block. Therefore, the lifting and adjusting is time-consuming and laborious. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a hanging wheel capable of lifting and adjusting, which solves the problem that the lifting and adjusting structure is time-consuming and laborious.

[0004] A hanging wheel capable of lifting and adjusting comprises a wheel seat, a lifting block and a driving block. Left wheel frames each equipped with a pulley and right wheel frames each equipped with a pulley are detachably installed on both sides of the wheel seat respectively. The lifting block is integrally formed by a lifting plate and a hanging box. The lifting plate extends out from inside the wheel seat, and the hanging box is arranged outside the wheel seat. The driving block is sleeved on the lifting plate inside the wheel seat. First inclined slots are arranged on both sides of the wheel seat, and a second inclined slot is arranged on the lifting plate. The first inclined slots and the second inclined slot are arranged in a crossed manner. The driving block and the lifting plate are horizontally connected through a driving shaft, and the driving shaft penetrates through the first inclined slots and the second inclined slot. One end of the driving block is threadedly connected with an adjusting screw rod, and the adjusting screw rod penetrates out from the end face of the wheel seat.

[0005] The cross section of the hanging box is in a T shape.

[0006] A baffle is arranged on one end face of the hanging box.

[0007] An installation groove is arranged at the bottom of the hanging box.

[0008] One end of each of the two sides of the wheel seat is provided with a slot with one end open and one end closed. The open end of the slot is on the side of the adjusting screw rod. The left wheel frames and the right wheel frames are slidably installed on the slots correspondingly along the upper and lower ends.

[0009] Grooves are arranged at the bottoms of the left wheel frames and the right wheel frames respectively. Corresponding to the grooves, screw holes are arranged at the bottom of the wheel seat. The screw holes and the grooves are connected through set screws.

[0010] Advantages of the present utility model: The lifting plate and the hanging box are set as an integrated structure, reducing the overall weight of the hanging box and the lifting plate. By adopting the first inclined groove and the second inclined groove and their cross-setting method, the driving shaft moves in two oblique directions, reducing the driving force required for the adjusting screw, and making the lifting movement of the lifting plate faster and more labor-saving. The left wheel frame, the right wheel frame and the wheel seat adopt a detachable assembly method of sliding insertion, realizing the convenience of quick installation and disassembly and replacement.

[0012] Figure 2 is Figure 1 exploded view of. Detailed Description of the Preferred Embodiment

[0013] The present utility model will be further described in detail below with reference to the drawings.

[0014] Figure 1 , 2 As shown in FIGS. Figure 1 and 2 , the liftable and adjustable hanging wheel includes a wheel seat 1, a lifting block 2 and a driving block 3. Left wheel frames 4 and right wheel frames 5 are installed on both sides of the wheel seat 1. Rotatable pulleys 6 are installed on both the left wheel frame 4 and the right wheel frame 5. One end of each of the slots 7, which are open at one end and closed at the other end, is provided on both sides of the wheel seat 1. The open end of the slot 7 is on the side of the adjusting screw 8. The left wheel frame 4 and the right wheel frame 5 are slidably installed in the slots 7 corresponding to the upper and lower ends. Grooves 9 are provided at the bottoms of both the left wheel frame 4 and the right wheel frame 5. Screw holes 18 corresponding to the grooves 9 are provided at the bottom of the wheel seat 1. The screw holes 18 and the grooves 9 are connected by set screws, thereby fixing the left wheel frame and the right wheel frame to the wheel seat. The left wheel frame, the right wheel frame and the wheel seat adopt a detachable assembly method of sliding insertion, realizing the convenience of quick installation and disassembly and replacement.

[0015] The lifting block 2 is integrally formed by a lifting plate 10 and a hanging box 11, reducing the overall weight of the hanging box and the lifting plate and reducing the load of the lifting of the lifting plate. The cross section of the hanging box 11 is T-shaped for installing the hanging box in the T-shaped groove of the top profile of the door body. A baffle 12 is provided at one end face of the hanging box 11 for positioning when installing the door body. An installation groove 13 is provided at the bottom of the hanging box 11. The hanging box is fixed to the top of the door body through the bolts in the installation groove.

[0016] The lifting plate 10 extends out of the wheel seat 1, the hanging box 11 is arranged outside the wheel seat 1, the driving block 3 is sleeved on the lifting plate 10 inside the wheel seat 1, the lifting plate 10 and the driving block 3 are installed in the through groove 14 of the wheel seat 1, the first inclined grooves 15 are arranged on both sides of the wheel seat 1, the second inclined grooves 16 are arranged on the lifting plate 10, the first inclined grooves 15 and the second inclined grooves 16 are arranged in a cross manner, the driving block 3 and the lifting plate 10 are horizontally connected through a driving shaft 17, the driving shaft 17 penetrates through the first inclined grooves 15 and the second inclined grooves 16, and one end of the driving block 3 is threadedly connected with an adjusting screw rod 8, and the adjusting screw rod 8 penetrates out of the end face of the wheel seat 1.

[0017] Turn the adjusting screw rod 8. Through the screw drive between the adjusting screw rod 8 and the driving block 3, the driving block 3 drives the driving shaft 17 to slide along the second inclined groove 16, and the driving shaft 17 pushes the lifting plate 10 to move obliquely. Under the combined limiting action of the first inclined groove 15 and the through groove 14, the lifting plate 10 completes the vertical movement, so as to achieve the purpose of driving the hanging box 11 to lift and adjust by the lifting plate 10. The cross arrangement of the first inclined groove and the second inclined groove enables the driving shaft to move in two oblique directions, reducing the driving force required for the adjusting screw rod and making the lifting movement of the lifting plate faster and more labor-saving.
