It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0028] The embodiments of the present utility model disclose a height - adjustable hanging wheel structure and a door body system having the height - adjustable hanging wheel structure. The height - adjustable hanging wheel structure of the present application can be specifically used to adjust the height of the door body to meet the user's usage requirements.

[0029] The following describes the height - adjustable hanging wheel structure of the present application in conjunction with the attached Figures 1 - 5 drawings.

[0030] In some embodiments, the height - adjustable hanging wheel structure is used to adjust the height of the door body and may specifically include a base 1. A hoisting hole 2 is vertically arranged in the base 1. An adjusting hole 3 communicated with the hoisting hole 2 is arranged in the base 1. A roller 4 is arranged on the base 1. The height - adjustable hanging wheel structure further includes a worm gear 5 rotatably arranged in the hoisting hole 2. The height - adjustable hanging wheel structure further includes a worm 6 rotatably arranged in the adjusting hole 3 and meshing with the worm gear 5. The worm 6 includes a meshing part 61 meshing with the worm gear 5 and a connecting rod section 62 fixed to the meshing part 61. The diameter of the connecting rod section 62 is smaller than the diameter of the meshing part 61. The adjusting hole 3 has hole sections respectively adapted to the diameters of the meshing part 61 and the connecting rod section 62.

[0031] On the premise of ensuring the height adjustment function, the internal workpieces and mating structures of this height-adjustable hanging wheel structure are improved to reduce the space occupied by itself and better apply to extremely narrow door bodies. The specific principle is as follows:

[0032] This height-adjustable hanging wheel structure specifically adopts the mating structure of a worm gear 5 and a worm 6 to adjust the height of the door body. In actual assembly, a lifting part is fixed on the door body, and the lifting part is threadedly connected to the worm gear 5. Therefore, the worm 6 can be specifically rotated to drive the worm gear 5 to rotate, and by using the principle of screw drive, the door body can be moved in the vertical direction, thereby realizing the height adjustment of the door body.

[0033] On the basis of this height-adjustment structure, in order to be well applied to extremely narrow door bodies, the structures of the worm 6 and the base 1 are improved. That is, after the meshing part 61 of the worm 6, which ensures sufficient structural strength, meshes with the worm gear 5, the connecting rod section 62 of the worm 6 is refined, so that the diameter of the connecting rod section 62 of the worm 6 is smaller than that of the meshing part 61 of the worm 6; and the hole section of the adjustment hole 3 on the base 1 is adaptively set according to the diameters of the meshing part 61 and the connecting rod section 62. That is, the hole section of the adjustment hole 3 for assembling the meshing part 61 is set as the meshing hole section, and the aperture at the meshing hole section is relatively large. The hole section of the adjustment hole 3 for the connecting rod section 62 is set as the connecting rod hole section, and the aperture at the connecting rod hole section is relatively small and is also refined accordingly. With such a setting, a narrowed area will also be formed at the part of the base 1 corresponding to the refined area described above.

[0034] It should be noted that since the entire structure of the worm in the height-adjustment structure of the existing hanging wheel structure is relatively thick, and the base of the existing hanging wheel structure itself also requires a certain thickness and the thickness of the rollers installed on the side of the base, the existing hanging wheel structure itself occupies a relatively large space. In this regard, the height-adjustable hanging wheel structure of this application refines the worm and narrows the corresponding position on the base. During actual assembly, the rollers will be specifically assembled in the narrowed area on the base, so that the overall height-adjustable hanging wheel structure of this application has been well narrowed and can be well applied to extremely narrow door bodies.

[0035] In summary, this height-adjustable hanging wheel structure specifically realizes the narrowing process of this height-adjustable hanging wheel structure by refining the connecting rod section 62 of the worm 6 and the hole section on the base 1 that mates with the connecting rod section 62 of the worm 6, so as to better apply to extremely narrow door bodies and can well increase the aesthetic degree of the extremely narrow door body series products.

[0036] In some embodiments, both the engaging portion 61 and the connecting rod segment 62 in the worm 6 can be integrally provided, for example, integrally formed. Since the engaging portion 61 and the connecting rod segment 62 are integrally formed, and their diameters are different, they cannot be directly assembled into place through the adjustment hole 3 of the base. In this regard, in a specific embodiment, the base 1 is assembled by two half-bodies 11. The facing surfaces of the two half-bodies 11 are respectively recessed with a hoisting half-hole 111 and an adjustment half-hole 112. The two hoisting half-holes 111 are used to be assembled into a hoisting hole 2, and the two adjustment half-holes 112 are used to be assembled into an adjustment hole 3. Since the connecting rod segment 62 of the worm 6 is refined, if the base 1 is still a whole, assembling the worm 6 into the base 1 will greatly increase the assembly difficulty. Therefore, for the convenience of the overall assembly and reducing the assembly difficulty, the base 1 is divided into two halves for assembly. Therefore, the hoisting half-hole 111 and the adjustment half-hole 112 are respectively machined on the two half-bodies 11. Therefore, during assembly, the worm gear 5 and / or the worm 6 can be specifically assembled into the hoisting half-hole 111 and the adjustment half-hole 112 in one of the half-bodies 11 respectively. Then, after the two half-bodies 11 are assembled together, the two hoisting half-holes 111 can be assembled into a hoisting hole 2, and the two adjustment half-holes 112 can be assembled into an adjustment hole 3, thus completing the assembly of this height-adjustable hanging wheel structure, which is convenient for assembly and effectively reduces the overall assembly difficulty.

[0037] In some embodiments, the engaging portion 61 and the connecting rod segment 62 in the worm 6 can be separately provided, for example, connected by clamping or threaded connection. Since the engaging portion 61 and the connecting rod segment 62 are separately provided, the base 1 can specifically be the structure assembled by two half-bodies 11 in the above-mentioned embodiment; or, in other embodiments, the base 1 may not be assembled by two half-bodies 11 and can specifically be a complete workpiece. A hoisting hole 2 and an adjustment hole 3 are machined in the base 1. During assembly, the engaging portion 61 can be assembled into place through the hoisting hole 2 and then assembled to the engaging hole section. The connecting rod segment 62 can be directly assembled through the adjustment hole 3, and then the engaging portion 61 and the connecting rod segment 62 are assembled and fixed together in the base 1.

[0038] Specifically, the two half-bodies 11 can be fixedly assembled through bolts and nuts.

[0039] In some embodiments, a driving portion 63 is provided at one end of the worm 6 away from the engaging portion 61, and the driving portion 63 is provided outside the base 1. The user can act on the driving portion 63 with a tool, and drive the entire worm 6 to rotate through the driving portion 63, so as to drive the rotation of the worm gear 5, and control the movement of the door body in the vertical direction, thereby realizing the height adjustment of the door body. Such a setting is convenient for the user to act on the worm 6 more conveniently and quickly, and reduces the operation difficulty.

[0040] In a specific embodiment, the driving part 63 is cylindrical, and the diameter of the driving part 63 is larger than that of the connecting rod section 62. With such a setting, the acting area of the driving part 63 can be increased, so that it is more convenient for the user to operate the worm 6 with a tool.

[0041] Specifically, the driving part 63 is provided with a slotted crosshead or a Phillips head slot. Since a slotted screwdriver or a Phillips head screwdriver is usually used for operation, a slotted crosshead or a Phillips head slot can be specifically provided on the driving part 63, which can make it more convenient for the user to operate with a tool.

[0042] In some embodiments, the adjusting hole 3 is inclinedly arranged in the base 1 and is inclined downward along the direction away from the hoisting hole 2. Since in actual assembly, this height-adjustable pulley structure will be specifically assembled on the upper side of the top of the door body, in order to facilitate the user to better operate the worm 6 in this height-adjustable pulley structure, the adjusting hole 3 is inclined downward. This means that the worm 6 assembled in the adjusting hole 3 will also be inclined downward correspondingly, and the user can better operate the driving part 63 on the worm 6, which is more convenient for operation.

[0043] In some embodiments, a limiting step 21 is arranged in the hoisting hole 2, and the limiting step 21 abuts against the bottom of the worm gear 5. Since the worm gear 5 will be specifically assembled in the hoisting hole 2, in order to better support the worm gear 5 to prevent the worm gear 5 from falling downward from the hoisting hole 2, a limiting step 21 for supporting the worm gear 5 is arranged in the hoisting hole 2 to better support the stable rotation of the worm gear 5 and effectively improve the overall structural stability.

[0044] In some embodiments, a limiting block 7 is clamped in the hoisting hole 2, and the limiting block 7 is arranged to abut against the top of the worm gear 5 to limit the movement of the worm gear 5 in the vertical direction. Since the height-adjusting function of the door body needs to be realized, the worm gear 5 cannot move in the vertical direction when it is driven by the worm 6 to rotate. Therefore, a clamped limiting block 7 is arranged in the hoisting hole 2, and the limiting block 7 is used to limit the movement of the worm gear 5 in the vertical direction. With such a setting, not only can the height-adjusting function of the door body be realized, but also the structure is more compact, effectively controlling the overall volume and being better applied to extremely narrow door bodies.

[0045] In a specific embodiment, a clamping groove 22 is concavely arranged on the inner side wall of the hoisting hole 2, and a clamping block 71 protrudes from the circumferential outer wall of the limiting block 7, and the clamping block 71 is clamped in the clamping groove 22. With such a setting, through the cooperation of the clamping block 71 and the clamping groove 22, the limiting function of the limiting block 7 is realized. The structure is simple, convenient for manufacturing and production, reducing the manufacturing difficulty, and at the same time the structure is compact, which can effectively control the overall volume.

[0046] An embodiment of the present utility model also discloses a door body system, which includes the above-mentioned height-adjustable hanging wheel structure. This door body system further includes a door body and an upper track 8 provided on the upper side of the door body. The height-adjustable hanging wheel structure is arranged in the upper track 8, and the worm gear 5 has internal threads. This door body system can specifically be an extremely narrow door body. Therefore, the upper track 8 itself will also be designed to be narrower. The thickness of the upper track 8 will be narrower than that of a conventional track. Therefore, this height-adjustable hanging wheel structure realizes the narrowing treatment of the height-adjustable hanging wheel structure by refining the connecting rod section 62 of the worm 6 and the hole section on the base 1 that is assembled with the connecting rod section 62 of the worm 6, and can be very adaptively assembled into the upper track 8. On the basis of realizing the height adjustment of the door body, it can be better applied to the extremely narrow door body to increase the aesthetic degree of the extremely narrow door body series products.

[0047] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the present utility model.
