Description

Technical Field

[0001] This application relates to the technical field of furniture, and particularly to a sofa armrest structure. Background Art

[0002] Sofas are essential household items in people's lives. Especially as common furniture in family life, they are generally used for rest. With the change of modern people's consumption concepts, the consumer group pays more attention to humanization when choosing products. Therefore, modern people increasingly focus on the matching and integrity of home furnishings. Currently, armrests are usually provided on both sides of the sofa. In order to facilitate placing items, existing sofas are equipped with a placement platform on one side for placing items. However, the placement platform occupies a large space, reducing the utilization rate of indoor space. Therefore, further improvement is needed. Utility Model Content

[0003] In order to improve the utilization rate of space, this application provides a sofa armrest structure.

[0004] The sofa armrest structure provided by this application adopts the following technical solutions:

[0005] A sofa armrest structure includes an armrest box disposed on one side of the sofa and a placement board main body disposed on the armrest box. An accommodation cavity is provided inside the armrest box. The placement board main body is hinged to the armrest box and can be folded and stored in the accommodation cavity.

[0006] By adopting the above technical solutions, an armrest box is provided on one side of the sofa, and a placement board main body is provided on the armrest box. When the placement board main body needs to be used, the placement board main body can be flipped out of the accommodation cavity. When not in use, the placement board main body is flipped into the accommodation cavity for storage, thereby improving the utilization rate of space.

[0007] Optionally, a cover plate is hinged to one side of the armrest box, and the cover plate is used to cover the upper opening of the accommodation cavity.

[0008] By adopting the above technical solutions, when the placement board main body is flipped into the accommodation cavity, the accommodation cavity is covered by the cover plate, reducing the possibility of sundries falling into the accommodation cavity.

[0009] Optionally, the placement board main body includes a connecting rod and a board body. One end of the connecting rod is hinged to the armrest box, and the board body is rotatably connected to the connecting rod around the axis direction of the connecting rod.

[0010] By adopting the above technical solutions, during use, the connecting rod rotates relative to the armrest box to turn the board body out of the accommodation cavity, and then the board body is rotated to a horizontal state.

[0011] Optionally, the armrest box is detachably connected with a mounting block, and the connecting rod is hinged to the mounting block.

[0012] By adopting the above technical solution, the connecting rod is arranged on the mounting block, and the mounting block is detachably connected to the armrest box, so that it is convenient to detach the plate body from the armrest box for cleaning the plate body.

[0013] Optionally, the armrest box is provided with a first clamping groove for clamping the mounting block. Sector-shaped grooves are formed in the side surfaces at both ends of the first clamping groove and away from each other. The center of the circle corresponding to the sector-shaped groove is located in the middle of the first clamping groove. The depth of the sector-shaped groove is less than that of the first clamping groove, and the bottom walls of the sector-shaped groove and the first clamping groove are flush.

[0014] By adopting the above technical solution, when installing the plate body, after the mounting block is clamped in the first clamping groove, the mounting block is rotated so that the mounting block is located in the sector-shaped groove, thereby limiting the mounting block.

[0015] Optionally, a steel ball is slidably connected to the mounting block in the vertical direction. The sector-shaped groove is provided with a second clamping groove for clamping the steel ball, and the mounting block is provided with a first spring for forcing the steel ball to be clamped in the second clamping groove.

[0016] By adopting the above technical solution, after the mounting block is rotated to a proper position and the steel ball is clamped in the second clamping groove, the mounting block is preliminarily limited.

[0017] Optionally, arc surfaces abutting against the side walls of the sector-shaped groove are arranged at both ends of the mounting block.

[0018] By adopting the above technical solution, arc surfaces are arranged at both ends of the mounting block to abut against the sector-shaped groove, thereby improving the stability of the installation of the mounting block.

[0019] Optionally, the armrest box is provided with a first clamping hole communicating with the sector-shaped groove, and the mounting block is provided with a second clamping hole. The mounting block can be rotated to a position where the first clamping hole and the second clamping hole are coaxially arranged, and the mounting block is provided with a pin inserted into the first clamping hole and the second clamping hole in sequence.

[0020] By adopting the above technical solution, when the mounting block is rotated to a proper position, the pin is inserted into the first clamping hole and the second clamping hole in sequence, thereby fixing the mounting block.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. An armrest box is provided on one side of the sofa, and a storage board main body is provided on the armrest box. When the storage board main body needs to be used, the storage board main body can be folded out from the accommodation cavity. When it is not needed, the storage board main body is folded into the accommodation cavity for storage, thereby improving the space utilization rate.

[0023] 2. The connecting rod is arranged on the mounting block, and the mounting block is detachably connected to the armrest box, so that it is convenient to detach the board from the armrest box for cleaning the board. Description of the Drawings

[0036] Referring to Figure 2 、 Figure 3 and Figure 4 a first clamping groove 13 for clamping the mounting block 3 is provided on one side of the armrest box 1 where the accommodation cavity 11 is located. The length direction of the first clamping groove 13 is parallel to the length direction of the armrest box 1. When installing the plate body 22, the mounting block 3 is clamped in the first clamping groove 13. Sector-shaped grooves 14 are provided on the side surfaces at both ends of the first clamping groove 13 along the width direction and are opened in a direction away from each other. The center of the circle corresponding to the sector-shaped grooves 14 is located in the middle of the first clamping groove 13. The depth of the sector-shaped grooves 14 is less than the depth of the first clamping groove 13, and the bottom walls of the sector-shaped grooves 14 and the first clamping groove 13 are flush. When the mounting block 3 is clamped in the first clamping groove 13, the connecting rod 21 and the mounting block 3 are rotated so that both ends of the mounting block 3 are rotated into the sector-shaped grooves 14, and the mounting block 3 is hooked in the sector-shaped grooves 14, thereby initially fixing the mounting block 3.

[0037] Referring to Figure 2 、 Figure 3 and Figure 4 sliding grooves 31 are provided on the lower surfaces at both ends of the mounting block 3 in the vertical direction. Steel balls 33 are provided on the mounting block 3 and are slidably connected to the sliding grooves 31.
