[0029] Embodiment 1

[0030] This embodiment provides an assembled sofa cushion bracket. As shown in the appended Figure 1 and appended Figure 2 figures, it includes a first connecting member 1 and a second connecting member 2 slidably connected to the first connecting member 1. The end of the second connecting member 2 away from the first connecting member 1 has an alignment strip 201 connected to the surface of the first connecting member 1, and a plurality of interconnected leveling members 3 are provided between the alignment strip 201 and the end of the first connecting member 1.

[0031] It should be noted that taking the contact surface of the entire bracket as the front, the second connecting member 2 is slidably connected to the back of the first connecting member 1, and there is a drop between the front of the second connecting member 2 extending to the outside of the first connecting member 1 and the front of the first connecting member 1. This drop is compensated by the leveling member 3. The compensation method is to determine the number of leveling members 3 connected along the length direction according to the length of the extension of the second connecting member 2 (i.e., the distance between the alignment strip 201 and the end of the first connecting member 1). Finally, the plane formed by the interconnected leveling members 3 is flush with the front of the first connecting member 1 and the alignment strip 201, ensuring that the contact surface of the entire bracket remains flat. Then, a soft package is covered to ensure the support and comfort of the cushion. The height of the alignment strip 201 is the same as the front of the first connecting member 1 on the front, which is convenient for positioning and installing the leveling structure 3 to ensure the accuracy and stability of the installation.

[0032] In this embodiment, two connecting seats 4 are respectively provided at the upper ends of the two ends of the main board 101 facing away from the sliding board 202. The connecting seats 4 can be fixedly connected or detachably connected. The main function is to enable the two ends of the bracket to selectively assemble swing parts. The swing part includes existing structures such as a hinge bracket and a support plate, so it will not be elaborated in this embodiment.

[0033] In this embodiment, two plug-in parts 5 are respectively provided at the lower ends of the two ends of the main board 101 facing away from the sliding board 202. The plug-in part 5 is an existing structure for connecting to the sofa main body, so it will not be elaborated in this embodiment.

[0034] In this embodiment, the first connecting member 1 includes a main board 101, two angle plates 102 provided on both sides of the main board 101 and extending along the length direction of the main board 101, and a plurality of first fixing screw holes 103 provided on the main board 101; the second connecting member 2 includes a sliding board 202 slidably connected to the two angle plates 102 at both ends, a second fixing screw hole 203 provided on the sliding board 202 and matching the first fixing screw hole 103, and a fastening bolt 204 for connecting the first fixing screw hole 103 and the second fixing screw hole 203.

[0035] Among them, the two angle plates 102 are installed on the upper and lower sides of the back surface of the main board 101, and the openings of the two angle plates 102 are arranged oppositely, which are used as the side-end slide rails of the sliding plate 202. The angle plates 102 and the main board 101 can be welded or integrally formed. The first fixing screw holes 103 are arranged on the back surface of the main board 101 that is not blocked by the angle plates 102, and a plurality of first fixing screw holes 103 are distributed at the same interval along the length direction of the main board 101 to improve the adjustment flexibility of the sliding plate 202. To further improve the stability, the first fixing screw holes 103 can also be arranged in two rows or multiple rows along the height direction of the main board 101. The number of the second fixing screw holes 203 is also multiple, and the interval is the same as that of the first fixing screw holes 103 to ensure that the second fixing screw holes 203 can match the first fixing screw holes 103, and the second fixing screw holes 103 are through holes to ensure that the fastening bolts 204 can directly penetrate through the sliding plate 202 and be connected to the main board 101. The fastening bolts 204 include screws and matching nuts that match the two fixing screw holes.

[0036] In this embodiment, the leveling member 3 includes a flat plate 301, two vertical plates 302 arranged at both ends of the flat plate 301 and connected to the surface of the second connecting member 2, two connecting screw holes 303 respectively arranged on the two vertical plates 302, and connecting bolts 304 arranged on the connecting screw holes 303; positioning screw holes 305 that match the connecting screw holes 303 are arranged on both the main board 101 and the alignment strip 201.

[0037] In this embodiment, the number of the positioning screw holes 305 is multiple and is distributed along the height direction of the main board 101 or the alignment strip 201. The purpose of such setting is to enable the leveling member 3 to be installed in layers to increase the support area at the sliding plate 202.

[0038] Among them, the flat plate 301 is vertically connected to the two vertical plates 302, and the connection method can be welding or integral forming. The flat plate 302 serves as a leveling layer flush with the front surface of the main board 101, and the end of the vertical plate 302 abuts against the front surface of the sliding plate 302 to play a supporting role to ensure the structural strength. The vertical plates 302 of the adjacent two leveling members located in the middle are connected to each other through the connecting bolts 304, and the vertical plates 302 of the leveling members located at the ends are respectively connected to the main board 101 and the alignment strip 201 through the connecting bolts 304.

[0039] It should be noted that since the area of the sliding plate 202 is smaller than the area of the main board 101, the plane finally formed by connecting the leveling members 3 is smaller than the main board 101 in height, and finally the front surface of the entire bracket presents a side T-shaped structure. However, the main body support area is sufficient, so after being covered with a soft package, there will be no shortage in terms of shape or support strength and other factors.

[0040] This embodiment provides an assembled sofa headrest support. Its operating principle is as follows: during transportation, the sliding plate 202 is stored behind the main plate 101, and multiple leveling members 3 are spliced and stacked. During use, the sliding plate 202 is first adjusted to a preset position and then secured with bolts 204. Finally, the leveling members 3 are spliced and installed between the alignment bar 201 and the end of the first connecting member 1 to form the final headrest support.

[0041] The advantages of an assembled sofa cushion bracket provided in this embodiment are: first, the bracket has a telescopic function, which can greatly reduce the space required for transportation during transportation and also reduce the risk of breakage; second, the leveling structure can supplement the difference between the main surface and the telescopic surface, ensuring the flatness of the bracket surface and improving the support strength and comfort.

[0042] Example 2

[0043] This embodiment optimizes the structure based on embodiment 1. Figure 3 , Attachment Figure 4 As shown:

[0044] The mainboard 101 is provided with a plurality of slots 306 that mate with the risers 302, the sliding plate 202 is provided with a plurality of insertion holes 307 that mate with the risers 302, and the flat plate 301 is provided with openings 308 that mate with the fastening bolts 204. The slots 306 and the first fixing screw holes 103 are spaced apart along the length of the mainboard 101, and the openings 308 are countersunk screw holes.

[0045] The advantage of this arrangement of the embodiment is that it further reduces the space occupied by the pillow bracket when stored: during transportation, the leveling structure 3 can be fixed to the back of the main board 101 by plugging the riser 302 into the socket 307 and the slot 306, and further secured by the fastening bolts 204. During installation, the redundant leveling structure 3 can still be fixed to the back of the main board 101, not taking up extra space and making it easier to store.

[0046] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
