Description

Technical Field

[0001] The utility model relates to the technical field of furniture accessories, in particular to a metal support foot for assembled furniture. Background Art

[0002] At present, finished furniture on the market is usually placed on the ground for support through support feet, so as to prevent the furniture bottom plate from directly contacting the ground. And for the convenience of transportation, the support feet are usually packaged separately from the furniture and assembled later.

[0003] Most of the metal support feet of existing furniture are integrally formed, which are difficult to adjust in height and have poor anti-slip performance. Especially when the support feet are used for supporting small-sized furniture such as bedside tables, due to the relatively light self-weight of the furniture itself, in daily use, such furniture is very easy to be collided and displaced during the cleaning process.

[0004] Therefore, we propose a metal support foot for assembled furniture. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a metal support foot for assembled furniture, which solves the problems mentioned in the above background.

[0006] The utility model provides the following technical solution: A metal support foot for assembled furniture includes a fixing plate and a support rod. The support rod is connected under the fixing plate, and an adjusting rod movably penetrates through the inside of the support rod. One end of the adjusting rod that penetrates out of the support rod is fixed with a chassis. A fixing disk is provided at the bottom port of the support rod, and a rotating cylinder is rotatably connected under the fixing disk. The rotating cylinder is threadedly connected with the adjusting rod to control the telescopic movement of the adjusting rod relative to the support rod. One end of the adjusting rod extending into the support rod is provided with a piston, which is in close contact with the inner wall of the support rod. An air passage is communicated inside the piston, the adjusting rod and the chassis.

[0007] Further, the fixing plate adopts an L-shaped structure, and a plurality of straight groove-shaped mounting holes are opened on the fixing plate.

[0008] Further, a convex platform is connected to the top end of the support rod, and an assembly hole that is in interference fit with the convex platform is provided on the lower surface of the fixing plate.

[0009] Further, a plurality of reinforcing ribs are provided at the connection between the chassis and the adjusting rod.

[0010] Further, an anti-slip foot pad is connected to the bottom of the chassis, and a perforation is provided on the anti-slip foot pad corresponding to the opening position of the air passage on the chassis.

[0011] Further, the fixing disk and the support rod are connected by a plurality of bolts.

[0012] Furthermore, the outer shape of the rotary drum adopts a hexagonal structure, and a number of anti-slip ridges are provided on the six outer side surfaces of the rotary drum.

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

[0014] When the rotary drum is rotated, the present utility model can drive the adjusting rod to telescopically move relative to the support rod by using the thread action between the rotary drum and the adjusting rod, thereby adjusting the height of the support feet, making it more flexible and convenient to use. At the same time, when the support rod moves, it can also drive the piston to move, thereby adjusting the pressure inside the support rod, so as to control the negative pressure state inside the support rod when the support feet are supporting, thereby improving the gripping ability of the support feet when supporting, making it not easy to shift, and making it more stable when supporting.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5A metal support foot for assembled furniture comprises a fixing plate 1 and a supporting rod 2. The fixing plate 1 is used to connect and fix with a bottom plate of the furniture. The fixing plate 1 adopts an L-shaped structure, and a plurality of straight slot-shaped mounting holes 11 are opened on the fixing plate 1, so that the fixing plate 1 is conveniently installed at the corner of the furniture. At the same time, the straight slot-shaped mounting holes 11 can be fine-tuned when screwing in screws, so as to be more quickly aligned with the connecting holes of the furniture. The supporting rod 2 is connected under the fixing plate 1 to support the furniture. An adjusting rod 3 is movably penetrated inside the supporting rod 2, and a chassis 4 is fixed to one end of the adjusting rod 3 passing through the supporting rod 2. A fixing plate 5 is provided at the bottom end of the supporting rod 2, and a rotating drum 6 is rotatably connected under the fixing plate 5. The adjusting rod 3 penetrates the fixing plate 5 and the rotating drum 6, and the rotating drum 6 is threadedly connected to the adjusting rod 3, so that when the rotating drum 6 rotates, the adjusting rod 3 is controlled to telescopically move relative to the supporting rod 2 by the action of the thread, thereby adjusting the supporting height of the supporting foot.

[0023] A piston 7 is installed at one end of the adjusting rod 3 extending into the support rod 2. The piston 7 is in close contact with the inner wall of the support rod 2, and an air passage 8 is passed through the piston 7, the adjusting rod 3 and the chassis 4. After the chassis 4 contacts the ground, when the adjusting rod 3 is further extended relative to the support rod 2, the piston 7 will be driven to move downward, thereby reducing the pressure in the internal space of the support rod 2 above the piston 7. The connecting effect of the air passage 8 is used to make the bottom of the chassis 4 have a negative pressure effect, thereby increasing its support stability and making it difficult to shift.

[0024] In order to facilitate the assembly connection between the support rod 2 and the fixed plate 1, a boss 21 is connected to the top of the support rod 2, and an assembly hole 12 with an interference fit with the boss 21 is provided on the lower surface of the fixed plate 1, so that the fixed plate 1 and the support rod 2 can be disassembled and assembled without the need for screw connection.

[0025] In order to improve the supporting strength of the chassis 4 , a plurality of reinforcing ribs 41 are provided at the connection between the chassis 4 and the adjusting rod 3 , and the strength of the chassis 4 and the adjusting rod 3 is enhanced by the reinforcing ribs 41 .

[0026] In order to further prevent the chassis 4 from shifting, a non-slip foot pad 42 is connected to the bottom of the chassis 4, and the non-slip foot pad 42 is provided with a perforation corresponding to the opening position of the air duct 8 on the chassis 4. The non-slip foot pad 42 is made of rubber material and can better fit the ground when in contact with the ground, thereby enhancing its firmness in adsorbing the ground.

[0027] In order to facilitate the assembly of the fixing plate 5 and the support rod 2 , the fixing plate 5 and the support rod 2 are connected by a plurality of bolts 51 , so that after the fixing plate 5 is removed, the piston 7 can be completely withdrawn from the support rod 2 .

[0028] In order to facilitate the user to control the rotation of the rotary drum 6, the outer shape of the rotary drum 6 is set to be a hexagonal structure, and a number of anti-slip ridges 61 are provided on each of the six outer side surfaces of the rotary drum 6. The length direction of the anti-slip ridges 61 is parallel to the axial direction of the rotary drum 6. Therefore, the friction between the user's hand and the rotary drum 6 can be increased, and the problem of slipping can be reduced.

[0029] Working principle: When in use, first use the hand to restrict the adjusting rod 3 and the chassis 4 from rotating. At this time, rotate the rotary drum 6, and the adjusting rod 3 will move telescopically relative to the support rod 2 to adjust the support height of the support feet. Then connect the fixing plate 1 to the bottom of the furniture so that the chassis 4 touches the ground. Again, keep the chassis 4 stationary and rotate the rotary drum 6. At this time, the adjusting rod 3 drives the piston 7 to move downward, and the pressure in the internal space of the support rod 2 above the piston 7 decreases. Thus, by using the connection function of the air passage 8, a negative pressure effect is generated at the bottom of the chassis 4.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
