[0031] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0033] See also Figure 1 and Figure 2 As shown, the utility model designs an adjustable limiting mechanism, which includes a fixed block 10 and a support rod 20. The fixed block 10 is provided with a tooth groove 11. The support rod 20 passes through the fixed block 10. One end of the support rod 20 close to the tooth groove 11 is connected to a gear 21. The gear 21 matches the tooth groove 11, and a limiting rod 30 is fixed on the gear 21.

[0034] It should be noted that the adjustable limiting mechanism of the present invention is connected to the back plate 43 of the furniture. When the limiting rod 30 needs to be adjusted, the gear 21 is disengaged from the tooth groove 11, and then the limiting rod 30 is rotated. When the limiting rod 30 is adjusted to match the back plate 43, the limiting rod is pressed down to make the gear 21 fall into the tooth groove 11 to achieve the locking of the limiting rod 30. It solves the technical problem that the limiting block of the prior art cannot be adjusted and can only adapt to furniture of a single size, and has low versatility.

[0035] Specifically, the limiting rod 30 includes an active limiting rod 31 and a driven limiting rod 32 . The gear 21 of the active limiting rod 31 is meshedly connected to the gear 21 of the driven limiting rod 32 , and the tooth groove 11 faces the gear 21 of the active limiting rod 31 .

[0036] It should be noted that when the gear 21 disengages from the tooth groove 11, the active limiting rod 31 is rotated counterclockwise, and the driven limiting rod 32 will rotate in the clockwise direction, and the angle between the active limiting rod 31 and the driven limiting rod 32 increases. At this time, the rear plate 43 with a relatively small size is adapted. The active limiting rod 31 is rotated clockwise, and the driven limiting rod 32 will rotate in the counterclockwise direction, and the angle between the active limiting rod 31 and the driven limiting rod 32 is reduced. At this time, the rear plate 43 with a relatively large size is adapted. After the adjustment is completed, the limiting rod is pressed down to make the gear 21 fall into the tooth groove 11 to achieve the locking of the limiting rod 30, which is very simple.

[0037] Specifically, the fixed block 10 is provided with a groove 12, in which a second connecting block 24 and an elastic member 22 in a compressed state are provided, the second connecting block 24 is connected to the support rod 20, the first end of the elastic member 22 is away from the tooth groove 11 and abuts the fixed block 10, and the second end of the elastic member 22 abuts the second connecting block 24.

[0038] Specifically, the adjustable limiting mechanism further includes a first connecting block 23 , and the first connecting block 23 is connected to an end of the support rod 20 away from the gear 21 .

[0039] The fixing block 10 of the utility model is provided with a through hole, and the support rod 20 passes through the through hole. The diameters of the first connecting block 23 and the second connecting block 24 are both larger than the diameters of the through hole, which can prevent the support rod 20 from being separated from the fixing block 10. The elastic member 22 is in a compressed state in the groove 12, and the first end of the elastic member 22 is away from the tooth groove 11 and connected to the fixing block 10, and the second end of the elastic member 22 abuts against the second connecting block 24. When no external force is applied, the elastic force provided by the elastic member 22 will push the gear 21 to be separated from the tooth groove 11, and the limiting rod 30 can be rotated relative to the fixing block 10 under force, and the limiting rod 30 can be adjusted to match the size of the furniture back panel 43. After the adjustment is completed, the limiting rod 30 is pressed down, and the second connecting block 24 will move the compression spring in the direction close to the first connecting block 23, and the gear 21 will be limited in the tooth groove 11.

[0040] See also Figure 3 and Figure 4 As shown, the utility model also designs a piece of furniture, which includes a side panel 42, a front panel 41 and a rear panel 43, the front panel 41 and the rear panel 43 are respectively arranged at the two ends of the side panel 42, the side panel 42, the front panel 41 and the rear panel 43 are enclosed to form a hollow supporting frame 40, the cushion 60 is located on the supporting frame 40, an adjustable limiting mechanism is connected to the rear panel 43, the screen frame 44 is connected to the front panel 41, and the screen frame 44 and the limiting rod 30 are both against the cushion 60.

[0041] It should be noted that after the adjustable limiting mechanism of the utility model is installed on the back plate 43, the gear 21 can be disengaged from the tooth groove 11, and then the active limiting rod 31 is rotated. When the active limiting rod 31 is adjusted to match the thickness of the back plate 43, the cushion 60 is placed on the support frame 40. Under the action of the gravity of the cushion 60, the gear 21 will be limited to the tooth groove 11, and the limiting rod 30 is in a locked state. The length of the cushion 60 is the same as the distance between the screen frame 44 and the back plate 43. The screen frame 44 and the limiting rod 30 are both in contact with the cushion 60, which can prevent the cushion 60 from sliding or shifting during use, providing the user with a more stable and comfortable use experience. In addition, the design of the screen frame 44 enables the user's back to be effectively supported when using furniture. This support can reduce the pressure on the back and allow the user to maintain a more comfortable posture.

[0042] Specifically, the rear plate 43 is provided with a threaded hole, and the fixing block 10 is provided with a through hole. When the adjustable limiting mechanism needs to be connected to the rear plate 43, the connecting piece is passed through the through hole and threadedly connected to the threaded hole. When the adjustable limiting mechanism or the rear plate 43 is damaged, the connecting piece is separated from the threaded hole and the through hole, and the adjustable limiting mechanism can be separated from the rear plate 43. Of course, the connection between the adjustable limiting mechanism and the rear plate 43 can also be achieved by other methods, and the present utility model does not limit this.

[0043] Specifically, the fixture further includes a support member 50 , and the support member 50 is fixedly connected to the bottom of the supporting frame 40 .

[0044] Specifically, the support member 50 includes a support leg 52 and a support plate 51 . The support plate 51 , the screen frame 44 and the front plate 41 are integrally formed, and the support leg 52 is connected to the rear plate 43 .

[0045] The support legs 52 and the support plate 51 of the utility model have the same height. The support plate 51 is connected to the front plate 41, and the support legs 52 are connected to the rear plate 43, which ensures that the support frame 40 can be separated from the bottom surface to facilitate subsequent floor cleaning. The one-piece molding makes the support plate 51, the screen frame 44 and the front plate 41 tightly connected.
