Description

Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to a novel furniture adjusting wheel. Background Technology

[0002] Furniture often needs to be leveled due to uneven ground or changes in user needs during daily use, so furniture wheels with adjustable functions are widely used.

[0003] In the existing technology, there are various structures for adjusting the height of furniture wheels, such as using threaded sleeves to directly raise and lower, or using pins to fix holes at different heights. However, these traditional adjustment methods may have problems such as limited adjustment stroke, complex structure and large space occupation, or easy loosening after adjustment and poor stability. It is difficult to achieve an ideal balance between structural compactness, adjustment convenience and reliability.

[0004] Therefore, we proposed a new type of furniture adjustment wheel to solve the above problems. Summary of the Invention

[0005] (a) Technical problems to be solved In view of the shortcomings of the prior art, this utility model provides a new type of furniture adjustment wheel, which solves the defects mentioned in the background art, such as the limited adjustment function, complex structure, or insufficient stability after adjustment of existing furniture adjustment wheels, and the difficulty in achieving compact structure, wide adjustment range and reliable locking at the same time.

[0006] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A novel furniture adjusting wheel includes a fixed wheel frame, an adjusting wheel frame movably disposed inside the fixed wheel frame, a wheel body movably disposed inside the adjusting wheel frame, and an adjusting screw passing through the interior of both the fixed wheel frame and the adjusting wheel frame.

[0007] Furthermore, a first wheel axle groove is provided on both sides of the fixed wheel frame, and the first wheel axle groove is inclined.

[0008] Furthermore, a second wheel axle groove is provided on both sides of the adjusting wheel frame, and the second wheel axle groove is inclined.

[0009] Furthermore, it also includes a wheel axle, which includes a male wheel axle head and a female wheel axle head. One end of the male wheel axle head and the female wheel axle head respectively passes through two first wheel axle grooves and a second wheel axle groove and is fixedly connected inside the wheel body.

[0010] Furthermore, the first wheel axle groove and the second wheel axle groove have opposite inclination directions and are combined in an X-shape.

[0011] Furthermore, the axle simultaneously mates with the first axle groove and the second axle groove, and the ends of the male axle and the female axle are located at the intersection of the first axle groove and the second axle groove.

[0012] Furthermore, one end of the adjusting screw extends to one side of the fixed wheel frame and is provided with a locking nut.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a novel furniture adjusting wheel, which has the following beneficial effects: This invention utilizes a single adjusting screw to drive the internal adjusting wheel frame to move horizontally. A linkage mechanism, consisting of a fixed wheel frame and two sets of first and second wheel axle grooves with opposite inclination directions on the adjusting wheel frame, forces the wheel axle to shift along the intersection of the first and second wheel axle grooves. This achieves stepless, smooth, and wide-range precise adjustment of the wheel height, efficiently converting limited horizontal movement into significant lifting. The design is reliable, compact, and includes a locking nut to ensure stability after adjustment. Attached Figure Description

[0016] 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.

[0017] Example like Figure 1-3 As shown, a novel furniture adjusting wheel according to an embodiment of the present invention includes a fixed wheel frame 1, an adjusting wheel frame 11 is movably disposed inside the fixed wheel frame 1, a wheel body 12 is movably disposed inside the adjusting wheel frame 11, and an adjusting screw 13 is passed through the interior of both the fixed wheel frame 1 and the adjusting wheel frame 11.

[0018] The fixed wheel frame 1 is used to install on furniture. The adjustable wheel frame 11 is an intermediate transmission component that can move within the fixed wheel frame 1. The wheel body 12 is the final load-bearing and moving component. The adjusting screw 13 is a driving element that passes through and connects the fixed wheel frame 1 and the adjustable wheel frame 11. Rotating the adjusting screw 13 can precisely control the relative position of the adjustable wheel frame 11.

[0019] Stable and linear height adjustment can be achieved with a single adjusting screw 13. The structure is compact and highly integrated, solving the problem of traditional furniture wheels having no height adjustment or inconvenient adjustment.

[0020] like Figure 1-3 As shown, in some embodiments, the fixed wheel frame 1 is provided with a first wheel axle groove 14 on both sides, and the first wheel axle groove 14 is inclined.

[0021] Inclined first wheel axle grooves 14 are opened on both sides of the fixed wheel frame 1 to provide a fixed inclined track for the movement of the wheel axle 16. The direction of this track determines the subsequent movement trajectory of the wheel axle 16 and the entire wheel body 12. The inclined first wheel axle grooves 14 are used to convert the horizontal movement of the adjusting wheel frame 11 into the movement of the wheel body 12. Its inclined design allows the wheel body 12 to be forced to rise and fall when the wheel axle 16 slides along it.

[0022] like Figure 1-3 As shown, in some embodiments, the adjusting wheel frame 11 is provided with a second wheel axle groove 15 on both sides, and the second wheel axle groove 15 is inclined.

[0023] Inclined second wheel axle grooves 15 are provided on both sides of the movable adjusting wheel frame 11. These grooves work together with the first wheel axle groove 14 on the fixed wheel frame 1 to constrain the movement of the wheel axle 16. This provides another key inclined track. Together with the first wheel axle groove 14, they form a dynamic "scissor-type" linkage mechanism, ensuring the stability and trajectory controllability of the wheel axle 16 during movement.

[0024] like Figure 1-3 As shown, in some embodiments, a wheel axle 16 is also included, the wheel axle 16 including a wheel axle male end 161 and a wheel axle female end 162, one end of the wheel axle male end 161 and the wheel axle female end 162 respectively passing through two first wheel axle grooves 14 and second wheel axle grooves 15 and being fixedly connected inside the wheel body 12.

[0025] The axle 16 adopts a split design of axle male 161 and axle female 162. Both ends pass through the first axle groove 14 of the fixed wheel frame 1 and the second axle groove 15 of the adjustable wheel frame 11 from the outside, and are finally connected and fixed inside the wheel body 12. This makes the axle 16, the wheel body 12 assembly and the first axle groove 14 and the second axle groove 15 on both sides slide in a sliding fit. The axle 16 effectively transmits the constraint force of the two first axle grooves 14 and the second axle groove 15 to the wheel body 12.

[0026] like Figure 1-3 As shown, in some embodiments, the first wheel axle groove 14 and the second wheel axle groove 15 have opposite inclination directions and are combined in an X-shape.

[0027] The sliding grooves on the fixed wheel frame 1 and the adjustable wheel frame 11 are combined in opposite directions of inclination to form an "X" shape intersection, which is the initial position of the wheel axle 16. The "X" shaped combination structure efficiently amplifies the limited horizontal displacement of the adjustable wheel frame 11 into a significant vertical displacement of the wheel body 12. When the adjusting screw 13 drives the adjustable wheel frame 11 to move horizontally, the relative position of the two sliding grooves with opposite inclination directions changes, and their intersection point moves accordingly. This greatly improves the sensitivity and range of height adjustment, intuitively reflects the large movement of the intersection point (i.e., the position of the wheel axle 16) in the vertical direction, and realizes stepless, smooth, and wide-range height adjustment. Moreover, the adjustment process is visible, making it convenient for users to accurately control the height of the furniture off the ground.

[0028] like Figure 1-3 As shown, in some embodiments, the axle 16 simultaneously mates with the first axle groove 14 and the second axle groove 15, and the ends of the axle male end 161 and the axle female end 162 are located at the intersection of the first axle groove 14 and the second axle groove 15.

[0029] The intersection point is the only common passage point of the two inclined tracks, ensuring the uniqueness and certainty of the movement of the wheel axle 16. No matter how the adjusting wheel frame 11 moves, the wheel axle 16 is forced to be positioned at the changing intersection point, thereby achieving absolute smoothness and no shaking during the height adjustment process, and improving the rigidity and reliability of the structure.

[0030] like Figure 1-3 As shown, in some embodiments, one end of the adjusting screw 13 extends to one side of the fixed wheel frame 1 and is provided with a locking nut 17.

[0031] A locking nut 17 is provided at the end of the adjusting screw 13 extending from the fixed wheel frame 1. After the height is adjusted to the correct position, the locking nut 17 is tightened so that it presses firmly against the side wall of the fixed wheel frame 1. The huge friction force prevents the adjusting screw 13 from rotating accidentally, providing a reliable anti-loosening locking function. This ensures that the adjusting screw 13 will not rotate on its own due to vibration or load changes during furniture use, thereby fixing the adjusted height and ensuring the stability and safety of the furniture.

[0032] In summary, by rotating the single adjusting screw 13, the internal adjusting wheel frame 11 is driven to move horizontally. The linkage mechanism formed by the fixed wheel frame 1 and the two sets of first wheel axle grooves 14 and second wheel axle grooves 15 with opposite inclination directions on the adjusting wheel frame 11 forces the wheel axle 16 to move along the intersection of the first wheel axle groove 14 and the second wheel axle groove 15, thereby achieving stepless, smooth and wide-range precise adjustment of the height of the wheel body 12. The limited horizontal movement is efficiently converted into significant lifting and lowering. The operation is reliable, the structure is compact, and a locking nut 17 is provided to ensure the stability after adjustment.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
