Technical Field

[0001] This utility model belongs to the field of rattan chair technology, and in particular relates to a modular rattan chair. Background Technology

[0002] Rattan chairs, as a model of home furnishing that blends traditional and modern craftsmanship, are loved by people for their unique natural charm and practical functions. They are made from carefully selected natural rattan, showcasing a simple yet elegant beauty. Rattan chairs are not only breathable, so you won't feel stuffy even after sitting for a long time in the summer, but they also have excellent toughness and elasticity, providing just the right amount of support and comfort for the body. Whether placed in the living room, balcony, or courtyard, rattan chairs can add a touch of freshness and comfort to the space with their unique style, allowing people to enjoy a moment of tranquility and relaxation in their busy lives.

[0003] The problem with existing technology is that the backrest frame and support of existing rattan chairs are usually assembled by bolts or welding. This makes assembly, disassembly, maintenance or replacement more troublesome and inconvenient, affecting the efficiency of assembly work. Utility Model Content

There are two pressing components 52, which are respectively located at the lower end of the two locking components 51. The linkage control component 53 is located on the left side of the lower end of the two pressing components 52.

[0025] The above solution is adopted: by setting up a quick-assembly device 5, the backrest frame 2 and the support 1 are quickly assembled and fixed, which facilitates the quick installation and fixing of the backrest frame 2, improves the convenience of subsequent disassembly and maintenance, and also makes it easy to quickly disassemble the chair into a flat stool.

[0026] refer to Figure 3 and Figure 4 The locking assembly 51 includes a positioning rod 511, a lock head 512, a push spring 513, and a slot 514. The positioning rod 511 is fixedly connected to the upper end of the front surface inside the box 4. The lock head 512 is sleeved on the surface of the positioning rod 511 and is slidably connected to the positioning rod 511. There are two push springs 513, which are respectively located on the left and right sides in front of the lock head 512. The front and rear ends of the two push springs 513 are fixedly connected to the front surface inside the box 4 and the front side of the lock head 512, respectively. The slot 514 is opened on the rear surface of the lock head 512.

[0027] The above solution is adopted: by setting a locking component 51, it is used to cooperate and snap into the connector 7 during assembly, thereby enabling the opening and installation of the backrest frame 2.

[0028] refer to Figure 3 and Figure 4The extrusion member 52 includes a slanted rod 521 and an extrusion groove 522. The slanted rod 521 is fixedly connected to the lower surface of the lock head 512, and the extrusion groove 522 is opened on the left surface of the slanted rod 521 and passes through the slanted rod 521.

[0029] The above solution is adopted: by setting up the pressing member 52, it is used to drive the locking component 51, and has the function of cooperating with the linkage control component 53 to move the locking component 51.

[0030] refer to Figure 3 and Figure 4 The linkage control component 53 includes a support rod 531, a movable plate 532, a pressure rod 533, and a tension / torque 534. The support rod 531 is fixedly connected to the lower inner surface of the box body 4. The movable plate 532 is sleeved on the upper surface of the support rod 531 and is slidably connected to the support rod 531. There are two pressure rods 533, which are fixedly connected to the front and rear ends of the right surface of the movable plate 532, respectively. The right ends of the two pressure rods 533 extend into the two extrusion grooves 522 and are movably connected to the extrusion grooves 522. The tension / torque 534 is fixedly connected to the left surface of the movable plate 532, and its left end extends out of the box body 4 and is movably connected to the box body 4.

[0031] The above scheme is adopted: by setting up a linkage control component 53, it is used to drive and control the quick-installation device 5. It can simultaneously link two pressing parts 52 to control the opening and closing movement of two locking components 51, which facilitates the control and release of the combination of the backrest frame 2.

[0032] refer to Figure 2 and Figure 3 The left and right sides of the lower surface of the backrest frame 2 are fixedly connected to the connectors 7 respectively. The positions of the two connectors 7 correspond to and are compatible with the positions of the two quick-release devices 5.

[0033] The above solution is adopted: by setting connectors 7 on the left and right sides of the lower surface of the backrest frame 2, they can cooperate and snap into the locking component 51 during assembly.

[0034] The working principle of this utility model:

[0035] During assembly, align the four limiting holes 3 at the lower end of the backrest frame 2 with the four positioning shafts 6 at the upper end of the support 1, and insert them into the surface of the positioning shafts 6 from top to bottom. This downward movement will cause the two couplings 7 to insert into the two housings 4, pressing the two locking heads 512 inside the housing 4. This causes the two locking heads 512 to move forward and backward on the surface of the positioning rod 511, simultaneously pressing the push spring 513. After the backrest frame 2 is fully in place, the lower end of the coupling 7 will correspond to the two slots 514. At this point, the push spring 513 will spring back, pushing the two locking heads 512 together, causing the lower end of the coupling 7 to insert forward and backward on both sides. Insert the insert into the slot 514 to complete the assembly. When disassembling, pull the pull knob 534 downward. The pull knob 534 drives the moving plate 532 to move downward on the surface of the support rod 531. At the same time, it drives the two pressure rods 533 to move downward and press the inner walls of the two pressing grooves 522 in the two pressing grooves 522. This causes the two inclined rods 521 to be pressed, which in turn drives the two locking heads 512 to move forward and backward on the surface of the positioning rod 511 to open, so that the connector 7 can be disengaged from the slot 514 and thus released from the fixation. Then, pull the backrest frame 2 upward to remove it to complete the disassembly, so that it can be disassembled into a flat stool for use or for repair and replacement.

[0036] In summary, this modular rattan chair, through the coordinated use of a support 1, backrest frame 2, limiting hole 3, box body 4, quick-installation device 5, locking component 51, positioning rod 511, lock head 512, push spring 513, slot 514, pressing component 52, diagonal rod 521, pressing groove 522, linkage control component 53, support rod 531, moving plate 532, pressure rod 533, tension / torsion 534, positioning shaft 6, and connector 7, solves the problem that existing rattan chairs, whose backrest frames and supports are usually assembled by bolts or welding, are usually troublesome to assemble and install, as well as to disassemble, repair, or replace, thus affecting the efficiency of assembly work.
