[0023] 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.

[0024] Example 1

[0025] like Figure 1-5 As shown, a modular sofa leg includes an upper fixed tube 1, a support column 2 is inserted into the interior of the upper fixed tube 1, the support column 2 is fixedly installed on the inner bottom wall of the protective base 3, the outer surface of the protective base 3 is sleeved with a protective cover 4, a positioning rod 5 is inserted into the interior of the protective cover 4, and one side of the positioning rod 5 is fixedly connected to a column 6, which passes through the upper fixed tube 1 and is inserted into the interior of the support column 2.

[0026] During specific use, through the coordination between the upper fixed tube 1, support column 2, protective base 3, protective cover 4, positioning rod 5, plug column 6, spring 7 and positioning hole 8, the protective cover 4 can wrap the protective base 3, which not only protects the protective base 3, but also the lower surface of the protective cover 4 contacts the ground, which can effectively avoid scratching the ground and reduce the probability of ground wear. When the protective base 3 or the protective cover 4 is damaged, the staff can directly remove and replace it, effectively reducing cost expenditure and facilitating subsequent maintenance. The staff can control the length of the support column 2 inserted into the upper fixed tube 1 according to the support height of the sofa, and then, under the action of the spring 7, the plug column 6 is inserted into the upper fixed tube 1 to limit the position of the support column 2, which is convenient for adjusting the height of the sofa. At this time, the positioning rod 5 can also be inserted into the positioning hole 8 to limit the protective cover 4, which can effectively prevent the protective cover 4 from detaching from the protective base 3.

[0027] In this embodiment, one side of the positioning rod 5 is connected to the outer surface of the upper fixing tube 1 via a spring 7 , and the normal state of the spring 7 is a compressed state.

[0028] During specific use, through the setting of the spring 7, after the positioning rod 5 loses the external force, the positioning rod 5 can be moved toward the upper fixed tube 1 to insert the insertion column 6 into the support column 2.

[0029] In this embodiment, positioning holes 8 are formed on the outer surfaces of the protective sleeve 4 and the protective base 3 , and the positioning rods 5 are inserted into the positioning holes 8 .

[0030] During specific use, by setting the positioning hole 8 and inserting the positioning rod 5 into the positioning hole 8 , the protective cover 4 can be effectively prevented from falling off from the protective base 3 .

[0031] In this embodiment, a limiting groove 9 is defined inside the upper fixed tube 1 , and a limiting protrusion 10 is slidably connected inside the limiting groove 9 . The limiting protrusion 10 is fixedly connected to the outer surface of the support column 2 .

[0032] During specific use, by providing the limiting groove 9 and the limiting protrusion 10 , the support column 2 can be inserted into the upper fixing tube 1 with better stability and less likely to be displaced.

[0033] In this embodiment, a fixing hole 11 is provided on the outer surface of the support column 2, and a plug column 6 is inserted into the fixing hole 11. A scale bar 12 is provided on the outer surface of the support column 2. The protective cover 4 is made of rubber, and anti-slip grooves are provided on the bottom of the protective cover 4.

[0034] During specific use, through the setting of the fixing hole 11 and the plug post 6, the plug post 6 is inserted into the fixing hole 11, so that the support column 2 can be connected to the upper fixing tube 1. Through the setting of the scale bar 12, the staff can easily adjust the height of the four sofa legs and adjust them to the same height. The anti-slip grooves set at the bottom of the protective cover 4 can play an anti-slip role, making the sofa legs more stable.

[0035] In this embodiment, a handle ring 13 is fixedly connected to the side of the positioning rod 5 away from the insertion column 6. The handle ring 13 is made of plastic. A mounting plate 14 is fixedly installed on the top of the upper fixing tube 1. The mounting plate 14 is fixedly connected to the four corners of the lower surface of the sofa by bolts.

[0036] During specific use, through the setting of the handle ring 13, the staff can insert their fingers into the handle ring 13 and then pull it outwards to remove the plug 6 from the fixing hole 11, so as to facilitate the adjustment of the height of the sofa leg.

[0037] Working principle: When in use, the staff can first place their fingers inside the handle ring 13, apply force outward, move the column 6 out of the fixing hole 11, and then control the depth of the support column 2 inserted into the upper fixing tube 1 according to the required height. Then, release the handle ring 13, and under the action of the spring 7, the column 6 can be reinserted into the fixing hole 11. After adjusting the sofa legs to the same height, turn the sofa over and place it directly on the ground, so that the sofa legs can support the sofa.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
