Description

Technical Field

[0001] This utility model relates to the field of sofa technology, and more specifically, to a sofa with a lifting mechanism. Background Technology

[0002] A sofa is a type of seating furniture with soft cushions such as springs or thick foam. It generally has a backrest and armrests and is usually composed of cushions and a frame. The frame is usually made of wood or steel and covered with genuine leather, synthetic leather or fabric. The interior is filled with materials such as cotton, sponge, horsehair, and bird feathers, giving people a soft and comfortable feeling. It is suitable for various occasions such as homes, offices, and leisure places.

[0003] In actual use, dust and other foreign objects accumulate between the bottom of the existing sofa and the ground. When users clean this dust and foreign objects, they need to move the sofa. Moving the sofa too far increases the user's physical exertion and reduces the practicality of the existing sofa. At the same time, there is no garbage collection structure when the user is using the sofa, so the garbage generated by the user cannot be collected. The user has to move the sofa to put the garbage into the trash can, which brings inconvenience to the use of the existing sofa.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sofa with a lifting mechanism, which has the advantages of being able to easily and effortlessly clean dust and other impurities from the bottom of the sofa, and having a garbage collection structure to facilitate the collection of garbage generated by users, thereby solving the problems in the background technology mentioned above.

[0006] To achieve the advantages of effortless and convenient cleaning of dust and other impurities from the bottom of the sofa, and having a waste collection structure for easy collection of user-generated waste, the specific technical solution adopted by this utility model is as follows:

[0007] A sofa with a lifting mechanism includes a sofa body, a base box installed at the lower part of the sofa body, a collection box installed at the rear end of the sofa body, an electrical control box installed on one side of the sofa body, and a control panel and a battery installed inside the electrical control box. A lead lever is installed inside the base box via bearings, and a lead screw sleeve is fitted onto the side wall of the lead lever. A lifting plate is fixedly fitted onto the side wall of the lead screw sleeve. Two sets of vertical rods slide through the upper part of the lifting plate, and the two ends of the two sets of vertical rods are fixedly connected to the top and bottom surfaces of the base box, respectively. A first spring and a connecting plate are slidably fitted onto the side walls of both sets of vertical rods. Four sets of support rods are installed at the lower part of the lifting plate, and the lower ends of the four sets of support rods slide through the bottom surface of the base box. Self-locking casters are installed at the lower ends of the four sets of support rods. A self-locking reversible motor is installed at the lower part of the base box, and the output end of the self-locking reversible motor is connected to the lead lever via a coupling.

[0008] Furthermore, the inner wall of the collection box is provided with a feed inlet and two sets of discharge outlets. A mounting screw slides through the rear end face of the collection box, and a baffle is installed on the inner end of the mounting screw. A mounting nut is sleeved on the side wall of the mounting screw. Two sets of mounting tubes are installed on the side wall of the collection box. Two sets of right-angle plates are installed on the side wall of each of the two sets of mounting tubes. Two sets of connecting rods slide through the far side of the two sets of right-angle plates on the same side. A limit plate is installed on one end of the two sets of connecting rods on the same side. An arc-shaped clamp is installed on the other side of the two sets of connecting rods on the same side. A second spring is sleeved on the side wall of each of the two sets of connecting rods on the same side.

[0009] Furthermore, the mounting screw and the mounting nut are threadedly engaged.

[0010] Furthermore, a door is installed on the end face of the bottom box via a hinge.

[0011] Furthermore, the lead lever and the lead screw thread are mutually engaged.

[0012] Furthermore, the control panel is electrically connected to the battery and the self-locking reversible motor via wires.

[0013] Furthermore, four sets of support seats are installed on the lower part of the base box.

[0014] Compared with the prior art, the present invention provides a sofa with a lifting mechanism, which has the following advantages:

[0015] (1) This utility model adopts a base box. When it is necessary to clean the dust and other impurities under the sofa body, the self-locking forward and reverse motor is activated by using the control panel. The output end of the self-locking forward and reverse motor can drive the lead lever to rotate. Since the lead lever and the lead screw sleeve are in mutual cooperation, the rotating lead lever can push the lead screw sleeve to move up or down. When the lead screw sleeve moves the four sets of support rods down through the lifting plate, the four sets of self-locking universal wheels can support the base box and the sofa body. When the lifting plate contacts the two sets of socket plates, the two sets of socket plates and the base box can squeeze the two sets of first springs, which can prevent the lifting plate from hitting the base box. At this time, the dust and other impurities under the sofa body can be cleaned. The sofa body can be finely adjusted with the help of the four sets of self-locking universal wheels. The two sets of guide rods can ensure the stability of the movement of the lifting plate. With the base box, the dust and other impurities under the sofa can be cleaned with ease and effort, which improves the usability of the sofa with the lifting mechanism.

[0016] (2) This utility model uses a collection box. Before actually using the sofa with the lifting mechanism, the user can move their hands away from the two sets of limiting plates on the same side. During this process, the two sets of arc-shaped clamps and the two sets of right-angle plates on the same side can squeeze the four sets of second springs on the same side. Then, the user can put two garbage bags on the side walls of the two sets of installation tubes and then release the two sets of limiting plates on the same side. The four sets of second springs on the same side, under their own elastic force, can push the two sets of arc-shaped clamps on the same side to reset. The two sets of arc-shaped clamps on the same side can hold a garbage bag. When the user generates garbage on the sofa body, the garbage can be put into the inside of the collection box through the inlet. The garbage can slide along the baffle and finally pass through the one set of outlets on the same side and the one set of outlets on the same side. The assembly tube falls into the inside of a garbage bag. When the garbage bag needs to be emptied, the user can rotate the mounting screw by hand. When the baffle rotates 90 degrees, the mounting screw and mounting nut engage with each other. The user then rotates the mounting nut clockwise. When the mounting nut contacts the collection box, the baffle is stably fixed. At this point, the garbage placed inside the collection box can fall into the inside of another garbage bag. At the same time, a garbage bag can be replaced. Repeating the above operation allows for alternating emptying of the garbage inside two garbage bags. The collection box, with its garbage collection structure, facilitates the collection of garbage generated by the user, bringing convenience to the use of sofas with lifting mechanisms.

The lower part of the base box 2 is equipped with a self-locking forward and reverse motor 12, and the output end of the self-locking forward and reverse motor 12 is connected to the screw lever 4 through a coupling. With the base box 2, it is possible to clean the dust and other impurities at the bottom of the sofa with ease and convenience, which improves the practicality of the sofa with the lifting mechanism.

[0030] In one embodiment, the inner wall of the collection box 3 is provided with an inlet 17 and two sets of outlets 18. A mounting screw 14 slides through the rear end face of the collection box 3, and a baffle 15 is installed at the inner end of the mounting screw 14. A mounting nut 16 is sleeved on the side wall of the mounting screw 14. Two sets of mounting tubes 19 are installed on the side wall of the collection box 3. Two sets of right-angle plates 20 are installed on the side wall of each of the two sets of mounting tubes 19. Two sets of connecting rods 21 slide through the far side of the two sets of right-angle plates 20 on the same side. A limit plate 22 is installed at one end of the two sets of connecting rods 21 on the same side. An arc-shaped clamp 23 is installed on the other side of the two sets of connecting rods 21 on the same side. A second spring 24 is sleeved on the side wall of each of the two sets of connecting rods 21 on the same side. The collection box 3 has a garbage collection structure, which can facilitate the collection of garbage generated by users and bring convenience to the use of sofas with lifting mechanisms.

[0031] In one embodiment, the mounting screw 14 and the mounting nut 16 are threaded together to facilitate adjustment of the position of the mounting nut 16.

[0032] In one embodiment, a door 13 is installed on the end face of the bottom box 2 via a hinge.

[0033] In one embodiment, the lead lever 4 and the lead screw sleeve 5 are threaded together to facilitate adjustment of the working position of the lead screw sleeve 5.

[0034] In one embodiment, the control panel is electrically connected to the battery and the self-locking forward and reverse motor 12 via wires. The control circuit of the control panel can be implemented by simple programming by those skilled in the art, and is common knowledge in the art. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0035] In one embodiment, four sets of support seats 25 are installed on the lower part of the base box 2.

[0036] Working principle:

[0037] When it is necessary to clean dust and other impurities under the sofa body 1, the self-locking forward and reverse motor 12 is activated using the control panel. The output end of the self-locking forward and reverse motor 12 can drive the lead lever 4 to rotate. Since the lead lever 4 and the lead screw sleeve 5 are threadedly engaged, the rotating lead lever 4 can push the lead screw sleeve 5 to move up or down. When the lead screw sleeve 5 moves the four sets of support rods 10 down through the lifting plate 6, the four sets of self-locking casters 11 can support the base box 2 and the sofa body 1. When the lifting plate 6 contacts the two sets of socket plates 9, the two sets of socket plates 9 and the base box 2 can compress the two sets of first springs 8, which can prevent the lifting plate 6 from hitting the sofa body 1. By pressing the bottom box 2, dust and other impurities under the sofa body 1 can be cleaned. The four self-locking casters 11 allow for fine-tuning of the sofa body 1, and the two guide rods ensure the stability of the lifting plate 6. The bottom box 2 allows for easy and convenient cleaning of dust and other impurities from the bottom of the sofa, improving the practicality of the sofa with a lifting mechanism. Before using the sofa with the lifting mechanism, the user can move their hands away from the two sets of limit plates 22 on the same side. During this process, the two sets of arc-shaped clamps 23 and the two sets of right-angle plates 20 on the same side can compress the four sets of second springs 24 on the same side. Afterwards, the user can... Place two garbage bags over the side walls of the two sets of mounting tubes 19, then loosen the two sets of limiting plates 22 on the same side. The four sets of second springs 24 on the same side, under their own elastic force, can push the two sets of arc-shaped clamps 23 on the same side back to their original position. The two sets of arc-shaped clamps 23 on the same side can hold one garbage bag. When the user generates garbage on the sofa body 1, the garbage can be placed into the collection box 3 through the inlet 17. The garbage can slide along the baffle 15 and finally fall into the inside of a garbage bag through the outlet 18 and the mounting tube 19 on the same side. When the garbage bag needs to be cleaned, the user can rotate the mounting screw 14 by hand. When the baffle 15 rotates 90 degrees, the mounting screw 14 and the mounting nut 16 engage with each other through their threads. The user can manually rotate the mounting nut 16 clockwise. When the mounting nut 16 contacts the collection box 3, the baffle 15 is stably fixed. At this time, the garbage placed inside the collection box 3 can fall into the inside of another garbage bag. At the same time, a garbage bag can be replaced. By repeating the above operation, the garbage inside the two garbage bags can be cleaned alternately. The collection box 3 has a garbage collection structure, which makes it easy to collect the garbage generated by the user and brings convenience to the use of sofas with lifting mechanisms.
