Abstract
Description
Technical Field
[0001] This utility model relates to the field of chair technology, and more specifically to a plastic chair with interlocking slats. Background Technology
[0002] The interlocking slat plastic chair is a type of plastic chair with a special structural design. It typically consists of two frames with I-beam shaped notches. These notches mainly guide the slats to be inserted and secured. There are usually eight slats in total, arranged in a box shape with built-in hooks and slots along the two outer edges. The slats interlock with the I-beam shaped notches of the frame through the hooks, forming the seat, backrest, and legs of the chair. The slats also pull and support each other, sharing the weight.
[0003] A search revealed a utility model patent with publication number CN205682836U, which discloses a plastic chair with interlocking slats. The chair is characterized by two chair frames and eight slats. The chair frames have eight I-beam-shaped notches for embedding and securing the slats. The slats are box-shaped with built-in hooks and slots on their outer edges. The slats secure the seat, backrest, and legs, and provide mutual traction, support, load-bearing capacity, and interlocking. The two chair frames are connected by the slat hooks to form the chair.
[0004] In this patent, the slats and chair frame are connected solely by snap fasteners. During long-term use, or when the chair is subjected to significant external forces, such as frequent moving, shaking, or heavy loads, the snap fastener connection will be continuously subjected to compression and stretching. This frequent stress can easily cause the snap fasteners to gradually loosen, or even deform or break, severely affecting the overall structural stability of the chair. An unstable chair often makes an unpleasant creaking sound during use, greatly reducing the user experience. Furthermore, since the snap fasteners are made of plastic, wear and tear is inevitable after repeated use. Over time, wear and tear will reduce the clamping force of the snap fasteners, significantly compromising the connection effect. This wear will be even more pronounced under frequent disassembly and assembly operations, which will undoubtedly shorten the normal lifespan of the chair. Utility Model Content

[0009] Furthermore, the elastic pad is a silicone plate, the elastic pad is U-shaped, and the surface of the elastic pad is attached to the inner wall of the slot.
[0010] Furthermore, there are two limiting grooves, positioning plates, and sliding plates. The two sliding plates are fixedly connected to both ends of the spring, and the center of the surface of the spring is fixedly connected to the outer surface of the fixing post.

[0023] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.
[0024] A plastic chair with interlocking slats includes two chair frames 1, with slat bodies 2 equidistantly interlocked on the surfaces of the two chair frames 1. The surfaces of the chair frames 1 are provided with slots 3 equidistantly, and the inner walls of the slots 3 are provided with insertion holes 4. The sides of the chair frames 1 are provided with positioning grooves 5, the number of positioning grooves 5 being equal to the number of slots 3. The surfaces of the slat bodies 2 are provided with grooves 6 at both ends, and elastic pads 7 are fixedly connected inside the grooves 6. The elastic pads 7 and the grooves 6 are matched in shape. An insertion rod 61 is fixedly connected at the center of the inner wall of the groove 6. A positioning component 8 is installed inside the slat bodies 2.
[0025] Specifically, the positioning component 8 includes a groove 81 formed on the surface of the slat body 2. The interior of the slat body 2 has limit grooves 82 formed on both sides of the groove 81. The groove 81 and the limit grooves 82 are connected internally. A positioning plate 83 is slidably connected inside the limit groove 82. A slide plate 84 is fixedly connected to the end face of the positioning plate 83. A fixing post 86 is fixedly connected to the center of the inner wall of the groove 81. A spring 85 is fixedly connected to the outer surface of the fixing post 86. The end face of the spring 85 is fixedly connected to the surface of the slide plate 84.
[0026] In this embodiment, by setting a laterally sliding positioning plate 83 inside the slat body 2, the slat body 2 is fastened to the chair frame 1 through the groove 6 and the slot 3. The initial positioning of the slat body 2 and the chair frame 1 is achieved by inserting the insert rod 61 into the insertion hole 4. At the same time, the slat body 2 is pressed down until the arc-shaped cross-section of the positioning plate 83 is engaged with the positioning groove 5, which can achieve a firm connection between the slat body 2 and the chair frame 1. Moreover, there is no wear on the connecting parts during the connection process. Even after multiple assembly and use, the stability of the connection can still be reliably guaranteed, thus extending the service life of the chair.
[0027] Specifically, the size of the insertion rod 61 matches that of the insertion hole 4, the outer surface of the insertion rod 61 is inserted into the inside of the insertion hole 4, the size of the slot 3 matches that of the groove 6, and the groove 6 and the slot 3 engage with each other.
[0028] In this embodiment, the position of the slat body 2 on the chair frame 1 can be initially positioned by the insertion of the insertion rod 61 and the insertion hole 4, and the positioning plate 83 can be accurately inserted into the positioning groove 5.
[0029] Specifically, the elastic pad 7 is a silicone plate, the elastic pad 7 is "U" shaped, and the surface of the elastic pad 7 is attached to the inner wall of the slot 3.
[0030] In this embodiment, by setting the elastic pad 7, the connection between the chair frame 1 and the slat body 2 can be buffered, reducing wear caused by hard contact of the connection surface, avoiding abnormal noises caused by shaking during the use of the chair, and improving the user experience.
[0031] Specifically, there are two limit grooves 82, positioning plates 83 and sliding plates 84. The two sliding plates 84 are fixedly connected to both ends of the spring 85. The center of the surface of the spring 85 is fixedly connected to the outer surface of the fixing post 86. The width of the sliding plate 84 is greater than the depth of the groove 81. The surface of the sliding plate 84 extends to the outer surface of the slat body 2.
[0032] In this embodiment, when the surface of the skateboard 84 extends to the outer surface of the board body 2, the two skateboards 84 can be pinched together by fingers, which can simultaneously drive the two positioning plates 83 to slide.
[0033] Specifically, the end of the positioning plate 83 away from the slide plate 84 is arc-shaped, and the end of the positioning plate 83 away from the slide plate 84 passes through the interior of the elastic pad 7 and is slidably connected to the interior of the groove 6.
[0034] In this embodiment, since the end of the positioning plate 83 away from the slide plate 84 is arc-shaped, no manual external force needs to be applied to the slide plate 84 when it is fastened. Through the elasticity of the spring 85, the positioning plate 83 can be automatically engaged in the positioning groove 5.
[0035] The working principle and usage process of this utility model are as follows: During assembly, the main body 2 of the slat is placed on the surface of the chair frame 1, and the groove 6 is aligned with the inside of the slot 3. At this time, the outer surface of the insert rod 61 is inserted into the inside of the insertion hole 4. Then, by applying downward pressure to the main body 2 of the slat, the insert rod 61 slides deeper into the insertion hole 4. At the same time, the arc-shaped surface of the positioning plate 83 abuts against the surface of the chair frame 1 and slides into the inside of the main body 2 of the slat. When the groove 6 and the slot 3 are fully engaged, the inner wall of the groove 6 is attached to the inner wall of the slot 3 by the insert rod 61. By setting the elastic pad 7, it can... The connection between the chair frame 1 and the slat body 2 is buffered, reducing wear caused by hard contact of the connection surface. This prevents abnormal noises caused by shaking during the chair's use, thus improving the user experience. The elasticity of the spring 85 allows the end face of the positioning plate 83 to be inserted into the positioning groove 5. Then, the remaining slat body 2 can be fixed and assembled onto the chair frame 1 in the same way. There is no wear on the connecting parts during the connection process. Even after multiple assembly and use, the stability of the connection can still be reliably guaranteed, extending the service life of the chair.
[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
