Description

Technical Field

[0001] The utility model relates to the technical field of sofa accessories, in particular to a sofa fixing device. Background Art

[0002] A sofa is a cushioned multi-seat chair with a backrest equipped with springs or thick foam plastics, and armrests on both sides. In order to prevent the sofa from moving due to force during use, causing the sofa to shift and affecting its use, foot pads are usually pasted to the bottom of the legs to increase the friction between the sofa and the ground.

[0003] According to a sofa and sofa legs disclosed (publication number: CN219306369U), a connection assembly is used as a structure for connecting and supporting two sofa seat frames in the above application. Therefore, only two connection assemblies are needed at the connection points of the two sofa seat frames, and there is no need to use two legs and two connecting cards in the prior art, thereby reducing the overall cost of the two sofa units. In addition, a foot pad is fixedly installed at the bottom end of the leg to increase the friction between the leg and the ground, so that the sofa can be placed more stably to avoid deviation.

[0004] However, during actual use of the above device, the foot pad will undergo slight elastic deformation when the sofa is normally placed. The anti-slip grooves on the bottom of the foot pad increase the friction between the foot pad and the ground. When the user sits on the sofa for a long time or places heavy objects on the sofa, the foot pad will be subjected to great pressure for a long time, causing irreversible elastic deformation, which will cause the anti-slip grooves to disappear. At this time, the foot pad loses its original anti-slip fixing effect, causing the sofa to easily shift, affecting the fixing effect of the sofa. In view of this, we propose a sofa fixing device.

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a sofa fixing device, comprising a base 1, a backrest 2 is fixedly installed at the rear end of the base 1, a supporting foot 3 is fixedly installed at the bottom end of the base 1, and a stabilizing component is arranged below the supporting foot 3.

[0024] The stabilizing assembly includes: a fixing rod 401, an externally threaded tube 406 and a bolt 407. The fixing rod 401 is fixedly installed at the bottom end of the supporting foot 3. The bottom end of the fixing rod 401 is fixedly installed with an anti-skid foot pad 402. The bottom of the anti-skid foot pad 402 is provided with anti-skid grooves. The sofa increases the friction between the sofa and the ground through the anti-skid foot pad 402, so that the sofa remains stable when placed on the ground, avoiding the sofa from shifting when the user sits on it.

[0025] A bearing 403 is fixedly installed on the outer side of the upper end of the fixed rod 401, and the inner wall surface of the inner ring of the bearing 403 is fixedly connected to the upper end of the fixed rod 401. A rotating cylinder 404 is fixedly installed on the outer ring of the bearing 403. The rotating cylinder 404 can rotate around the fixed rod 401 under the action of the bearing 403. The rotating cylinder 404 is sleeved on the outer side of the fixed rod 401, and the inner wall surface of the bottom end of the rotating cylinder 404 is provided with an internal thread 405. The external threaded cylinder 406 is threadedly connected to the inner bottom end of the rotating cylinder 404. The external threaded cylinder 406 is sleeved on the fixed rod 401, and the anti-slip foot pad 402 is sleeved inside the external threaded cylinder 406. When the rotating cylinder 404 rotates, the cooperation of the internal thread 405 can drive the external threaded cylinder 406 to perform linear motion in the up and down directions on the outer side of the fixed rod 401.

[0026] When the sofa is placed, the anti-skid foot pad 402 will be squeezed and elastically deformed. At this time, the rotating cylinder 404 can be rotated to make the external threaded cylinder 406 move downward to a position in contact with the ground. At this time, the external threaded cylinder 406 supports the sofa as a whole. When people sit on the sofa and apply downward pressure, the external threaded cylinder 406 can prevent the pressure from being applied to the anti-skid foot pad 402, thereby preventing the anti-skid foot pad 402 from being further compressed and causing irreversible deformation, causing the anti-skid pattern on the bottom of the anti-skid foot pad 402 to disappear, causing the anti-skid foot pad 402 to lose its original anti-skid and friction-increasing effects, thereby affecting the fixing effect of the sofa.

[0027] The bolt 407 is arranged at the right end of the rotating cylinder 404, and the bolt 407 is threadedly connected to the inner wall of the rotating cylinder 404. The left end of the bolt 407 penetrates through the right surface of the rotating cylinder 404 and is fixedly installed with a fixing plate 408. The left end of the fixing plate 408 is fixedly installed with a rubber plate 409. When the external threaded cylinder 406 moves to the desired position, the rotatable bolt 407 drives the rubber plate 409 to move to the left side through the fixing plate 408, so that the rubber plate 409 is deformed and closely fits with the left end of the fixing rod 401, thereby limiting the rotating cylinder 404, preventing the rotating cylinder 404 from rotating due to external force, causing the external threaded cylinder 406 to leave its position, affecting the limiting effect on the anti-slip foot pad 402, and the fixing effect on the sofa.

[0028] An observation groove 501 is provided at the bottom end of the external threaded barrel 406. The user can observe the positional relationship between the external threaded barrel 406, the anti-slip foot pad 402 and the ground through the observation groove 501, which is convenient for the staff to adjust the position of the external threaded barrel 406. A scale bar 502 is provided on the left side surface of the external threaded barrel 406. The user can directly observe the moving position of the external threaded barrel 406 through the scale bar 502, so that the user can synchronously and accurately control the air of the external threaded barrel 406 at the four corners, thereby reducing the user's adjustment time.

[0029] In the present invention, when in use, after the sofa is placed in the desired position, the anti-skid foot pad 402 will be squeezed, so that the anti-skid foot pad 402 will be elastically deformed, increasing the friction between the anti-skid foot pad 402 and the ground, so that the sofa can remain stable when placed on the ground, and avoid the sofa from shifting when the user sits on it. Then, the rotating cylinder 404 can be rotated to drive the external thread cylinder 406 to move downward, so that the bottom end of the external thread cylinder 406 fits with the ground. At this time, the external thread cylinder 406 can limit the deformation of the anti-skid foot pad 402, and avoid the user applying downward pressure when sitting on the sofa, leading to The anti-skid foot pad 402 is further deformed, resulting in the disappearance of the anti-skid pattern at the bottom, affecting the limiting effect of the sofa, causing the sofa to easily deviate, affecting the fixing effect of the sofa. When the external threaded tube 406 moves to the desired position, the rotatable bolt 407 drives the rubber plate 409 to move to the left, so that the rubber plate 409 is tightly fitted with the right side surface of the fixing rod 401, thereby limiting the rotating tube 404, preventing the rotating tube 404 from rotating due to a slight external force, causing the external threaded tube 406 to leave the desired position, affecting the limiting effect of the anti-skid foot pad 402.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
