[0031] Example 2:
[0032] The difference between this embodiment and embodiment 1 is that the foot pedal assembly 3 includes a groove 31, a foot pedal 32, a rotating shaft 33, a magnetic strip 34 and a magnetic strip 35. The base 1 has grooves 31 on both sides of its front end, and a foot pedal 32 is provided in the groove 31. The foot pedal 32 is connected to the base 1 by the rotating shaft 33. A magnetic strip 34 is snapped into one end of the foot pedal 32. A magnetic strip 35 is glued to the position in the groove 31 corresponding to the magnetic strip 34.
[0033] By adopting the above technical solution, when a person sitting on the sofa is too short to reach the ground with their feet, the foot pedal 32 can be pulled. The foot pedal 32 rotates in the groove 31 via the pivot 33. After the foot pedal 32 rotates to a horizontal position, the lower end of the groove 31 supports and limits the foot pedal 32, allowing the person to place their feet on it. When the foot pedal 32 is not in use, it can be pushed into the groove 31, and the magnetic strip 34 on the foot pedal 32 will attract the magnetic strip 35 in the groove 31, thus achieving the effect of storing and fixing the foot pedal 32 in the groove 31. By setting the foot pedal assembly 3, the feet of shorter people can be supported, preventing the person sitting on the sofa from not being able to reach the ground with their feet, which would reduce comfort.
[0034] Specifically, one end of the magnetic strip 34 is flush with the side of the foot pedal 32, and the pivot 33 is connected to the base 1 by a damped rotation. After the foot pedal 32 is stored in the groove 31, the side of the foot pedal 32 does not protrude from the side of the base 1.
[0035] By adopting the above technical solution, the magnetic strip 34 is prevented from protruding from the foot pedal 32 and easily falling off. The rotating shaft 33 and the base 1 are connected by a damping rotation to prevent the rotating shaft 33 and the foot pedal 32 from rotating on their own. After the foot pedal 32 is put into the groove 31, the side of the foot pedal 32 does not protrude from the side of the base 1 to prevent the foot pedal 32 from protruding from the groove 31 and scratching the people sitting on the sofa.
[0036] In this embodiment, by setting up the foot pedal assembly 3, when a person sitting on the sofa is too short to reach the ground with their feet, the foot pedal 32 is pulled. The foot pedal 32 rotates in the groove 31 via the pivot 33. After the foot pedal 32 rotates to a horizontal position, the lower end of the groove 31 supports and limits the foot pedal 32, allowing the person to place their feet on the foot pedal 32. When the foot pedal 32 is not in use, it is pushed into the groove 31, and the magnetic strip 34 on the foot pedal 32 is attracted to the magnetic strip 35 in the groove 31, achieving the effect of storing and fixing the foot pedal 32 in the groove 31. By setting up the foot pedal assembly 3, the feet of shorter people can be supported, avoiding the situation where the feet of shorter people sitting on the sofa cannot reach the ground, thus reducing comfort.
[0037] In this utility model, the motor 25 is a previously disclosed technology, and the selected model is 5IK120GN-CF.
[0038] The structure and working principle of the base 1, support 4, armrest 5, seat cushion 6 and backrest 7 of this utility model have been disclosed in a sofa that facilitates cleaning of crevices, as disclosed in Chinese patent application number 2018207451265.
[0039] The working principle and usage process of this utility model are as follows: When using the sofa that is easy to lift and clean, the device is installed in a suitable position. By setting up the lifting component 2, when it is necessary to clean the floor under the sofa, the motor 25 is turned on to drive the rotating rod 26 to rotate. The rotation of the rotating rod 26 drives the worm gear 28 to rotate. The rotation of the worm gear 28 drives the screw 24 to rotate in the cavity 21 through the worm wheel 27. The rotation of the screw 24 drives the sliding plate 22 to move downward in the cavity 21. The movement of the sliding plate 22 lifts the base 1 upward through the sliding column 23. By setting up the lifting component 2, the sofa can be lifted, thus facilitating the cleaning of the floor under the sofa. By setting up the inspection component 29, the mounting bolt 294 can be unscrewed from the mounting hole 295, and the inspection plate 291 can be removed from the inspection port 296. At the same time, the positioning plates 292 at both ends of the inspection plate 291 are removed from the positioning groove 293. The access panel 296 allows for the inspection and maintenance of the motor 25 within the cavity 21. The inspection and maintenance component 29 facilitates the inspection and maintenance of the motor 25. The foot pedal component 3 allows for easy access to the floor when a person sitting on the sofa is too short to reach the ground. Pulling the foot pedal 32 causes it to rotate within the groove 31 via the pivot 33. Once the foot pedal 32 is in a horizontal position, the lower end of the groove 31 provides support and limits its movement, allowing the person to place their feet on it. When not in use, the foot pedal 32 is pushed back into the groove 31, where the magnetic strip 34 on the foot pedal 32 attracts the magnetic strip 35 in the groove 31, effectively securing the foot pedal 32 within the groove. The foot pedal component 3 provides support for shorter individuals, preventing them from being unable to reach the ground and reducing comfort when sitting on the sofa.
