[0002] "Sofa" is a loanword, which is a cushioned multi-seat chair with a backrest equipped with springs or thick foam plastics, and armrests on both sides. It is a kind of soft furniture. The origin of the sofa can be traced back to ancient Egypt around 2000 BC, but the true upholstered sofa appeared in the late 16th century and early 17th century. As the name suggests, the sofa leg is the "foot" of the sofa, which serves to support the sofa.

[0003] Most of the current sofa legs only have a supporting function, but do not have the function of adjusting the height. Since different people have different requirements for sofa height, the function is single, and the current sofa legs do not have the function of adjusting the supporting area. For different user groups, some pursue a silent effect, while others pursue narrow-sized legs that are easy to clean. Therefore, it is necessary to design a sofa leg that is easy to adjust the height. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example

[0024] like Figure 1-5 As shown, a sofa leg that is easy to adjust in height includes a support tube 1, a mounting plate 2 is fixedly connected to the upper surface of the support tube 1, a notch 3 is formed on the front surface of the support tube 1, a connecting rod 4 is rotatably connected to the inner side wall of the notch 3, a gear 5 is fixedly connected to the middle portion of the outer surface of the connecting rod 4, and a handle 6 is fixedly connected to one end of the connecting rod 4;

[0025] In this embodiment, the other end of the connecting rod 4 is fixedly connected to the ratchet 7, and a sliding groove is provided on the lower surface of the support cylinder 1. A movable plate 8 is slidingly connected inside the sliding groove, and a rack 9 is fixedly connected to the front of the movable plate 8. The rack 9 is meshed with the gear 5.

[0026] When in use, the support leg is first fixed to the bottom of the sofa by means of the mounting plate 2 and screws. When the height of the sofa support leg needs to be adjusted, the connecting rod 4 can be rotated in the notch 3. After turning the handle 6, the connecting rod 4 can be driven to rotate the gear 5. The movable plate 8 can slide inside the slide groove, and the rack 9 and the gear 5 are meshed with each other. After the handle 6 drives the gear 5 to rotate, the rack 9 is subjected to a force, causing the movable plate 8 to slide in the slide groove, thereby adjusting the height of the sofa support leg. The ratchet 7 is convenient for cooperating with the inclined surface of a specific structure to produce a one-way limit function.

[0027] In this embodiment, a vertical plate 10 is fixedly connected to one side of the support tube 1, and a limiting rod 11 is slidably connected to one side of the vertical plate 10. One end of the limiting rod 11 passes through one side of the vertical plate 10 and extends to the other side of the vertical plate 10.

[0028] During specific use, the sliding effect between the limiting rod 11 and the vertical plate 10 is utilized to enable the limiting rod 11 to have a transverse sliding function, so as to facilitate the inclined surface to be inserted into the slot of the ratchet 7 .

[0029] In this embodiment, an inclined surface is formed at one end of the limiting rod 11 , and a spring 12 is sleeved on an end of the outer surface of the limiting rod 11 close to the inclined surface.

[0030] During specific use, after the gear 5 rotates, the rack 9 receives the force, causing the movable plate 8 to slide downward to increase the height of the support leg. The inclined surface of the limit rod 11 is used to squeeze the limit rod 11 to one side when the ratchet 7 rotates. At this time, the spring 12 is compressed. After stopping rotation, the spring 12 rebounds and pushes the limit rod 11 to get stuck in the groove of the ratchet 7. When the sofa is pressed by gravity to move the movable plate 8, a limiting effect can be generated to prevent the movable plate 8 from sliding.

[0031] In this embodiment, a pull ring 13 is fixedly connected to one end of the limiting rod 11 away from the inclined surface.

[0032] When the height of the sofa legs needs to be lowered, the pull ring 13 is used to conveniently pull the limit rod 11 out of the ratchet 7, so that the connecting rod 4 drives the gear 5 to rotate, so that the movable plate 8 is retracted into the slide groove.

[0033] In this embodiment, a sliding groove 14 is formed on the inner side wall of the movable plate 8 , and a limiting hole 15 is formed on the inner top wall of the movable plate 8 .

[0034] During specific use, the sliding groove 14 enables the cross column 16 to slide, and the limiting hole 15 is adapted to the size of the limiting rings at the four ends of the cross column 16 to facilitate clamping the cross column 16.

[0035] In this embodiment, a cross column 16 is slidably connected to the interior of the sliding groove 14 , and one end of the cross column 16 is rotatably connected to a universal wheel 17 .

[0036] When it is used specifically, when it needs to be moved, one end of the cross column 16 with the universal wheel 17 is moved to the bottom, and the universal wheel 17 is used to facilitate movement.

[0037] In this embodiment, a rubber pad 18 is fixedly connected to one end of the cross column 16 , a first support leg 19 is fixedly connected to one end of the cross column 16 , and a second support leg 20 is fixedly connected to one end of the cross column 16 . The first support leg 19 and the second support leg 20 have different sizes.

[0038] When in use, lift and rotate the cross column 16 so that the end of the rubber pad 18 contacts the ground, which has a silent effect. Rotate the first leg 19 and the second leg 20 of different widths to contact the ground, and the area in contact with the ground can be adjusted. The narrow leg is suitable for cleaning.

[0039] Working principle: During use, first fix the support leg to the bottom of the sofa through the mounting plate 2 and screws for use. When the height of the sofa leg needs to be adjusted, the connecting rod 4 can be rotated in the notch 3. After turning the handle 6, the connecting rod 4 can be driven to rotate the gear 5, and the movable plate 8 can slide inside the slide groove, and the rack 9 and the gear 5 are meshed with each other. After the handle 6 drives the gear 5 to rotate, the rack 9 is subjected to a force, so that the movable plate 8 slides in the slide groove, thereby adjusting the height of the sofa leg. The inclined surface of the limit rod 11 is used to squeeze the limit rod 11 to one side when the ratchet 7 rotates. At this time, the spring 12 is compressed. After stopping rotation, the spring 12 rebounds and pushes the limit rod 11 to be stuck in the ratchet 7 groove. When the sofa is pressed by gravity to move the movable plate 8, a limiting effect can be generated to avoid The movable plate 8 does not need to slide. When the user needs to move the sofa, the cross column 16 has a sliding effect in the sliding groove 14. First, lift one leg of the sofa and then slide the cross column 16 downward so that the end of the cross column 16 with the universal wheel 17 is at the bottom. After releasing the sofa, the supporting leg is squeezed by the weight, so that the opposite cross column 16 is stuck in the limiting hole 15, thereby limiting the cross column 16 to prevent rotation. At this time, the universal wheel 17 is used for easy movement. If you need to choose a supporting leg with a good silent effect, you can lift it again and rotate the cross column 16 so that the end of the rubber pad 18 contacts the ground, which has a silent effect. The rotation makes the first supporting leg 19 and the second supporting leg 20 of different widths contact the ground, and the area in contact with the ground can be adjusted. The narrow foot is suitable for cleaning, and the wide foot increases the anti-slip property, with different functions.
