Description

Technical Field

[0001] This application relates to the field of recliner frame technology, and in particular to a leg connection structure for a recliner frame. Background Technology

[0002] In daily life and leisure settings, recliners are widely used in family living rooms, balconies, outdoor courtyards, and other recreational areas due to their comfortable reclining experience. The leg support structure of a recliner, as a core component supporting the overall weight of the recliner and ensuring safety during use, often bears considerable pressure.

[0003] To ensure convenience during use and storage, some recliners adopt a foldable structure. Therefore, the fixation of their legs during use is crucial. Existing recliners often use relatively complex connection structures, such as the table and chair frame connection structure and folding chair proposed by the applicant in publication number CN220832427U. The limiting components are relatively complex. Furthermore, conventional structures such as pins and ordinary buckles are also not easy to use. Therefore, the purpose of this application is to solve the above problems.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a support leg connection structure for a recliner frame to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is a support leg connection structure for a recliner frame, including: a horizontal tube with a rotating connecting part installed at its bottom, on which a connecting tube and a rotating shaft are fixedly installed; and a support leg with a connecting block fixedly installed at its top, the connecting block being rotatably disposed below the rotating connecting part via the rotating shaft, the connecting block having two opposing pressing blocks, and a connecting groove formed between the pressing blocks. When the support leg rotates, the connecting tube can drive the two pressing blocks outward under the action of external force, so that the connecting tube is completely inserted into the connecting groove. Afterward, the pressing blocks are reset, so that the connecting tube cannot be disengaged from the connecting groove without the action of external force.

[0007] In some embodiments, the extrusion block has extrusion sections, and the width of the connecting groove formed between two extrusion sections is smaller than the diameter of the connecting pipe.

[0008] In some embodiments, the extrusion block has a receiving section, and a connecting groove formed between two receiving sections can fully accommodate the connecting tube.

[0009] In some embodiments, the connecting block is made of a resiliently recoverable material.

[0010] In some embodiments, the connecting block is provided with a deformation groove, and the extrusion block located at the center of the connecting block can move into the deformation groove when it is extruded by the connecting pipe.

[0011] In some embodiments, the tops of the extrusion block and the connecting block can form a limiting surface that fits against the rotating connection portion.

[0012] The beneficial effects of this application are as follows: by rotating the connecting part and the connecting block, the connecting tube can cooperate with the extrusion block when the support leg rotates. As the support leg continues to rotate, the extrusion blocks on both sides are forced to be extruded and deformed outward, so that the connecting tube can be quickly locked and released. At the same time, the limiting of the connecting tube is achieved by the fit between the top of the connecting block and the rotating connecting part, which can limit the maximum rotation distance of the connecting tube.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0019] In the embodiments of this application, please refer to Figure 1-3 As shown, this application provides a support leg 2 connection structure for a recliner frame, mainly including: a horizontal tube 1, the bottom of which is equipped with a rotating connecting part 11, on which a connecting tube 111 and a rotating shaft 112 are fixedly disposed; a support leg 2, the top of which is fixedly disposed with a connecting block 21, the connecting block 21 being rotatably disposed below the rotating connecting part 11 via the rotating shaft 112, the connecting block 21 having two opposing pressing blocks 211, and a connecting groove 212 formed between the pressing blocks 211. When the support leg 2 rotates, the connecting tube 111 can drive the two pressing blocks 211 outward under the action of external force, so that the connecting tube 111 completely enters the connecting groove 212. Afterward, the pressing blocks 211 reset, so that the connecting tube 111 cannot disengage from the connecting groove 212 without the action of external force.

[0020] Specifically, if you want to prop up the support leg 2 when it is folded, you can rotate the support leg 2 to make the connecting block 21 rotate along the pivot 112. After the connecting tube 111 contacts the pressing block 211, the support leg 2 continues to rotate. The two pressing blocks 211 are subjected to greater pressure and elastically deform to both sides, causing the connecting tube 111 to enter the connecting groove 212. After being subjected to the pressure of the pressing block 211, the connecting tube 111 is difficult to disengage from the connecting groove 212 unless a force is actively applied to rotate the support leg 2 in the opposite direction. To unlock the support leg 2 from the unfolded state, you need to rotate the support leg 2 in the opposite direction and apply external force to make the connecting tube 111 overcome the elastic force of the pressing block 211 and exit from the connecting groove 212, thus completing the unlocking.

[0021] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0022] Reference Figure 3As shown, the extrusion block 211 has an extrusion section 2111, and the width of the connecting groove 212 formed between the two extrusion sections 2111 is smaller than the diameter of the connecting pipe 111. When the connecting pipe 111 enters the connecting groove 212, it must first be squeezed by the guide surface of the extrusion section 2111 to force the two extrusion blocks 211 to deform outward to widen the inlet width, ensuring that the connecting pipe 111 can enter. At the same time, since the width of the extrusion section 2111 is smaller than the diameter of the connecting pipe 111, after the connecting pipe 111 enters, the extrusion section 2111 always exerts an inward extrusion force on the connecting pipe 111, enhancing the stability of the connection and preventing the connecting pipe 111 from accidentally detaching.

[0023] Preferably, the extrusion block 211 has a receiving section 2112, and the connecting groove 212 formed between the two receiving sections 2112 can completely accommodate the connecting pipe 111. When the connecting pipe 111 passes through the extrusion section 2111 and enters the receiving section 2112, the arc-shaped inner wall of the receiving section 2112 is in close contact with the connecting pipe 111, which not only restricts the radial sway of the connecting pipe 111, but also disperses the pressure of the connecting pipe 111 on the extrusion block 211 through the arc surface, avoiding excessive local stress that could damage the extrusion block 211. At the same time, it ensures that the connecting pipe 111 is stably placed in the receiving section 2112, further improving the structural strength of the support leg 2 after it is deployed.

[0024] Specifically, the connecting block 21 is made of an elastically recoverable material, such as rubber or plastic. These materials have good elastic deformation ability and recovery performance. When the connecting tube 111 squeezes the squeezing block 211, the squeezing block 211 can produce a small amount of elastic deformation outward, ensuring that the connecting tube 111 smoothly enters the connecting groove 212. When the external force is removed, the squeezing block 211 can quickly return to its initial shape, and its inner side is tightly fitted with the connecting tube 111. The elastic force of the material locks the connecting tube 111 in the connecting groove 212, preventing it from falling out.

[0025] Preferably, the connecting block 21 has a deformation groove 213. When the extrusion block 211 located at the center of the connecting block 21 is extruded by the connecting pipe 111, the extrusion block 211 can move into the deformation groove 213. The deformation groove 213 provides sufficient deformation space for the extrusion block 211, preventing the extrusion block 211 from breaking due to excessive force.

[0026] Reference Figure 2-3As shown, the tops of the compression block 211 and the connecting block 21 can form a limiting surface 214 that fits against the rotating connecting part 11. The setting of the limiting surface 214 can limit the maximum rotation angle of the support leg 2, preventing the connecting tube 111 from disengaging from the connecting groove 212 or the compression block 211 from being damaged due to excessive rotation of the support leg 2. At the same time, for the obliquely set support leg 2, the limiting surface 214 can remain parallel to the horizontal tube 1 during use, and the force is concentrated on the limiting surface 214. At the same time, when the limiting surface 214 is compressed, the connecting groove 212 will be locked, and the two compression blocks 211 will be restricted by the pressure of the limiting surface 214, making it difficult for them to deform into the shape, further improving the locking effect in the unfolded state.
