Description

Technical Field

[0001] The present application relates to the field of chairs, and in particular to a tapered chair leg structure. Background Art

[0002] The chair provides a comfortable and stable sitting and lying space for users, providing excellent support for dining, resting, and entertainment. Its advantages lie in its user-friendly design, which conforms to ergonomic principles and effectively relieves fatigue caused by prolonged sitting. Furthermore, the diverse material and style options cater to the aesthetic and practical needs of different family members, creating a warm and comfortable home environment.

[0003] A chair generally includes a frame, a seat cushion, and chair legs. The seat cushion is arranged on the frame to provide support for the user. The chair legs are arranged on the frame to provide good support for the user sitting on the seat cushion. In order to reduce the risk of deformation or breakage of the chair legs along the frame, there is a method as shown in the attached manual. Figure 3 The chair legs shown include a support rod and a mounting base. The support rod is fixedly connected to the mounting base. The support rod is connected to the frame using bolts through the mounting base, which is conducive to promotion and application.

[0004] However, this type of chair leg has a mounting seat structure, which makes its overall volume (or size) relatively large. For some chair legs with higher requirements on appearance, additional coverings or shielding parts are required to cover the connection between the mounting seat and the frame. The operation is complicated and there is room for improvement. Utility Model Content

[0005] In order to improve the convenience of chair leg installation, the present application provides a tapered chair leg structure.

[0006] The present application provides a tapered chair leg structure that adopts the following technical solution:

[0007] A tapered chair leg structure includes a support rod, which includes a main center rod and a threaded section. The threaded section is fixedly connected to the main center rod and is used for threaded connection to a frame. The outer wall of the main center rod is provided with a coating layer, and the coating layer is used to enhance the rigidity of the support rod.

[0008] By adopting the above technical solution, the connection between the main center rod and the frame is achieved through the threaded section. At the same time, the rigidity of the support rod is enhanced by utilizing the cooperation of the coating layer, thereby reducing the probability of the support rod being deformed or broken along the frame after being installed on the frame. Compared with the method of using a mounting seat to connect the chair legs and the frame, the installation method of the chair legs of this application is simpler and more stable.

[0009] Preferably, an anti-slip member is provided at one end of the main center rod away from the end connected to the threaded section.

[0010] By adopting the above technical solution, the anti-slip parts are helpful to increase the anti-slip performance of the chair legs.

[0011] Preferably, the thickness of the coating layer is gradually reduced from one end close to the threaded section to one end close to the anti-slip part.

[0012] By adopting the above technical solution, when the support rod is subjected to external force, the thickness of the coating layer is gradually reduced from the end close to the threaded section to the end close to the anti-slip part, which is conducive to concentrating the stress on the end of the support rod close to the threaded section, further reducing the probability of deformation or breakage of the support rod, and also helping to improve the overall appearance quality.

[0013] Preferably, the coating layer is chamfered at one end close to the threaded section.

[0014] By adopting the above technical solution, the chamfered structure is utilized to enable the covering layer to fit the frame after the threaded section is threadedly connected to the frame, thereby increasing the tightness of the connection between the covering layer and the frame.

[0015] Preferably, a latch is provided at one end of the covering layer away from the threaded section, and the anti-slip part is engaged with the latch.

[0016] By adopting the above technical solution, since there are preset snap positions on the covering layer, when installing the anti-slip part, it is only necessary to snap the anti-slip part into engagement with the snap positions. The installation method is simple and no additional tools are needed to fix the anti-slip part.

[0017] Preferably, a layer is provided on the outside of the coating layer.

[0018] By adopting the above technical solution, the layer is helpful to improve the appearance quality of the tapered chair leg structure, and the layer can be changed according to actual needs, which is highly practical.

[0019] Preferably, the support rods are electroplated.

[0020] By adopting the above technical solution, the support rod is electroplated, which is beneficial to enhancing the surface hardness and corrosion resistance of the support rod and improving the service life of the support rod.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The main center rod is connected to the frame through the threaded section. At the same time, the rigidity of the support rod is enhanced by the cooperation of the coating layer, thereby reducing the probability of deformation or breakage of the support rod along the frame after the support rod is installed. Compared with the method of connecting the chair legs to the frame using a mounting base, the installation method of the chair legs of the present application is simpler and more stable.

[0023] 2. Nylon fiber has good impact resistance and strong strength. The nylon fiber material is helpful to enhance the overall rigidity of the support rod and reduce the probability of deformation or breakage of the support rod when force is applied to the support rod;

[0024] 3. Because there are preset snap-in positions on the covering layer, when installing the anti-slip part, you only need to snap the anti-slip part into place, which is easy to install without the need for additional tools to fix the anti-slip part. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The present application embodiment discloses a tapered chair leg structure. Figure 1 and Figure 2 A tapered chair leg structure includes a support rod 1, the support rod 1 includes a main center rod 11 and a threaded section 12, the threaded section 12 is fixedly connected to the main center rod 11, the threaded section 12 is used to be threadedly connected to the frame, and the outer wall of the main center rod 11 is provided with a coating layer 2, which is used to enhance the rigidity of the support rod 1.

[0031] Specifically, the support rod 1 is cut from metal and then machined. The main center rod 11 and the threaded section 12 are integrally formed, which reduces the probability of fracture at the connection between the threaded section 12 and the main center rod 11.

[0032] It should be noted here that after the support rod 1 is processed and formed, the support rod 1 is electroplated, which is beneficial to enhancing the surface hardness and corrosion resistance of the support rod 1 and improving the service life of the support rod 1.

[0033] Furthermore, after the support rod 1 is processed and formed, the support rod 1 is placed in an injection mold, and the covering layer 2 is covered on the main center rod 11 by injection molding. At the same time, the threaded section 12 is exposed to facilitate the threaded connection between the threaded section 12 and the frame.

[0034] At the same time, the covering layer 2 is set as a nylon fiber-reinforced covering layer 2. Nylon fiber-reinforced has good impact resistance and strong strength. The nylon fiber-reinforced material is conducive to enhancing the overall rigidity of the support rod 1 and reducing the probability of deformation or breakage of the support rod 1 when force is applied to the support rod 1.

[0035] Correspondingly, the thickness of the coating layer 2 gradually decreases from the end near the threaded section 12 to the end near the anti-slip member 3. When the support rod 1 is subjected to external forces, the thickness of the coating layer 2 gradually decreases from the end near the threaded section 12 to the end near the anti-slip member 3, which helps to concentrate the stress on the end of the support rod 1 near the threaded section 12, further reducing the probability of deformation or fracture of the support rod 1, and also helps to improve the overall appearance quality.

[0036] In addition, one end of the covering layer 2 close to the threaded segment 12 is chamfered. The chamfered structure enables the covering layer 2 to fit with the frame after the threaded segment 12 is threadedly connected to the frame, thereby reducing the gap between the covering layer 2 and the frame and increasing the tightness of the connection between the covering layer 2 and the frame. After the threaded segment 12 is connected to the frame, the covering layer 2 uses the chamfered structure to fit with the frame synchronously, thereby playing a role in sharing the force and reducing the probability of the threaded segment 12 being broken or deformed due to excessive force acting on the threaded segment 12.

[0037] Reference Figure 1 and Figure 2 The main center rod 11 is provided with an anti-skid piece 3 at one end away from the end connected to the threaded section 12. The anti-skid piece 3 is helpful to increase the anti-skid performance of the chair legs.

[0038] Specifically, the anti-slip member 3 can be a non-slip rubber pad or a non-slip rubber plug, and can be connected to the covering layer 2 by gluing. In this embodiment, a latch 4 is preferably provided at the end of the covering layer 2 away from the threaded section 12, and the anti-slip member 3 engages with the latch 4. The latch 4 is integrally formed with the covering layer 2 through injection molding, eliminating the need for secondary processing of the latch 4.

[0039] Therefore, since the covering layer 2 is pre-set with the locking position 4, when installing the anti-slip part 3, it is only necessary to engage the anti-slip part 3 with the locking position 4. The installation method is simple and no additional tools are needed to fix the anti-slip part 3.

[0040] In addition, a layer is provided on the outside of the covering layer 2, and the layer can be a sticker, etc. In this embodiment, preferably, the layer is printed on the covering layer 2 by water transfer printing, so that the covering layer 2 has a wood texture, which enhances the sensory experience of the user when using it.

[0041] The implementation principle of the tapered chair leg structure of the embodiment of the present application is: the connection between the main center rod 11 and the frame is achieved through the threaded section 12. At the same time, the rigidity of the support rod 1 is enhanced by utilizing the cooperation of the coating layer 2, thereby reducing the probability of the support rod 1 being deformed or broken along the frame after the support rod 1 is installed on the frame. A layer is provided on the outside of the coating layer 2, and the coating layer gives the coating layer 2 a wood texture, which is highly practical.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
