Description

Technical Field

[0001] The utility model relates to the technical field of sofas, in particular to a sofa which is easy to move. Background Art

[0002] The sofa has become a necessary furniture for many families. It 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, usually used for rest or receiving guests. It usually consists of two or more seats, each with a cushion, a backrest and armrests, which is very suitable for lying down or sitting to rest. Sofas are generally made of wood, but wood materials easily attract pests, causing the sofa to be eaten by insects, so the deworming of wooden sofas has become a matter of attention in daily life.

[0003] After searching, Chinese patent application (announcement) No. 202323239465.6 discloses an insect-repellent sofa. The patent uses a fan to increase the diffusion speed of the insect-repellent fragrance, so that the insect-repellent fragrance spreads outward to the surrounding area of ​​the sofa body to achieve the effect of repelling insects. Although the above patent has the effect of repelling insects, the sofa does not have the function of cleaning the ground underneath. After long-term use, dust is easily accumulated under the sofa. Ordinary cleaning tools are difficult to clean the narrow space, which causes dust to accumulate easily. In addition, the current sofas are not convenient to move. The legs of most sofas are fixed, which makes it time-consuming and laborious to move them. Therefore, it is necessary to design a sofa that is easy to move. Utility Model Content

[0010] In order to achieve a rotating effect, as a sofa that is easy to move according to the utility model, the front side of the vertical board is rotatably connected with a worm, and the worm is meshingly connected with a worm wheel.

[0011] In order to facilitate the rotation, as a sofa that is easy to move in the utility model, one end of the worm is fixedly connected to a handle, and one end of the worm passes through the front side of the vertical board and extends to the back side of the vertical board.

[0012] In order to enable the sofa to rotate by itself, as a sofa that is easy to move, a motor is installed on one side of the vertical board, and the output end of the motor is fixedly connected to the reciprocating screw rod.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, through the arrangement of the reciprocating screw, the slider, the slide groove and the fan, during use, before cleaning, the slider can be subjected to the force of the thread through the rotation of the reciprocating screw, and when the reciprocating screw rotates, it can drive the slider to slide in the slide groove, and the reciprocating screw continues to rotate to make the slider move back and forth. At this time, after starting the fan, wind force is generated to blow downward, which can blow out the dust at the bottom of the sofa, thereby achieving the effect of cleaning the ground below and avoiding the trouble of inconvenient cleaning in a narrow space.

[0015] 2. In the utility model, through the arrangement of the transmission rod, the worm wheel, the self-locking wheel and the worm, when the sofa needs to be moved during use, one end of the sofa can be lifted up and off the ground first, and the worm can be rotated by the handle. By utilizing the meshing effect of the worm and the worm wheel, the worm drives the worm wheel to rotate so that the transmission rod is rotated, and the supporting leg is rotated to the top. At this time, the self-locking wheel is located at the other end of the supporting leg. Then, the other end of the sofa is lifted up according to the same operation, so that the self-locking wheel is rotated to the bottom. At this time, the sofa can be directly pushed to move, which has the effect of facilitating movement. When it needs to be fixed, only one end needs to be lifted up again, and the worm can be rotated to make the end of the anti-slip pad of the supporting leg to the bottom.

A protection frame 8 is fixedly connected to the lower surface of the slider 6 , and a fan 9 is installed inside the protection frame 8 .

[0026] When in use, before cleaning, the slider 6 can be subjected to the force of the thread through the rotation of the reciprocating screw 5. When the reciprocating screw 5 rotates, it can drive the slider 6 to slide in the slide groove 7. The reciprocating screw 5 continues to rotate to make the slider 6 move back and forth. At this time, the fan 9 is started to generate wind force blowing downward, which can blow out the dust at the bottom of the sofa, thereby achieving the effect of cleaning the ground below.

[0027] In this embodiment, a U-shaped plate 10 is fixedly connected to the lower surface of the bottom plate 1 , and a transmission rod 11 is rotatably connected to the inner side wall of the U-shaped plate 10 .

[0028] During specific use, the transmission rod 11 has a rotating effect in the U-shaped plate 10, which facilitates the switching of the support legs 13 and the self-locking wheels 14.

[0029] In this embodiment, one end of the transmission rod 11 passes through the inner wall of the U-shaped plate 10 and extends to the outer surface of the U-shaped plate 10 , and one end of the transmission rod 11 is fixedly connected to the worm gear 12 .

[0030] When in use, the worm wheel 12 is fixed to one end of the transmission rod 11 , and the worm wheel 12 can drive the transmission rod 11 to rotate after receiving a force.

[0031] In this embodiment, a support leg 13 is fixedly connected to one side of the outer surface of the transmission rod 11 , a self-locking wheel 14 is rotatably connected to the bottom end of the support leg 13 , and an anti-slip pad 15 is fixedly connected to the top end of the support leg 13 .

[0032] When in use, when one end of the self-locking wheel 14 touches the ground, it is convenient to push. After the transmission rod 11 rotates, the self-locking wheel 14 is flipped to the top. At this time, the anti-slip pad 15 is located at the lower end and then touches the ground, which has a supporting and fixing effect.

[0033] In this embodiment, a worm 16 is rotatably connected to the front side of the vertical plate 4 , and the worm 16 is meshingly connected to the worm wheel 12 .

[0034] During specific use, the meshing effect between the worm 16 and the worm wheel 12 is utilized, and the worm 16 drives the worm wheel 12 to rotate so that the transmission rod 11 has a rotation effect.

[0035] In this embodiment, one end of the worm 16 is fixedly connected to a handle 17 , and one end of the worm 16 passes through the front side of the vertical board 4 and extends to the back side of the vertical board 4 .

[0036] When in use, the handle 17 can be used to facilitate the rotation of the worm 16 , and the positioning can be stopped after the worm 16 is released by utilizing the one-way transmission effect of the worm 16 .

[0037] In this embodiment, a motor 18 is installed on one side of the vertical plate 4 , and the output end of the motor 18 is fixedly connected to the reciprocating screw rod 5 .

[0038] When in use, the motor 18 is started to drive the reciprocating screw rod 5 to rotate, thus achieving a transmission effect.

[0039] Working principle: During use, before cleaning, the motor 18 is started to drive the reciprocating screw 5 to rotate, so that the slider 6 can be subjected to the force of the thread. When the reciprocating screw 5 rotates, it can drive the slider 6 to slide in the slide groove 7. The reciprocating screw 5 continues to rotate to make the slider 6 move back and forth. At this time, the fan 9 is started to generate wind force to blow downward, which can blow the dust at the bottom of the sofa outward, so as to achieve the effect of cleaning the ground below, avoiding the trouble of inconvenient cleaning in a small space. When the sofa needs to be moved, one end of the sofa can be lifted up and off the ground. The worm 16 is rotated by the handle 17. By utilizing the meshing effect of the worm 16 and the worm wheel 12, the worm 16 drives the worm wheel 12 to rotate so that the transmission rod 11 rotates, and the supporting leg 13 is rotated to the top. At this time, the self-locking wheel 14 is located at the other end of the supporting leg 13. The other end of the sofa is lifted up according to the same operation to rotate the self-locking wheel 14 to the bottom. At this time, the sofa can be directly pushed to move, which has the effect of facilitating movement. When it needs to be fixed, it only needs to lift one end again and rotate the worm 16 to make one end of the anti-slip pad 15 of the supporting leg 13 to the bottom.
