Description

Technical Field

[0001] The utility model relates to the technical field of outdoor products, and more specifically, to a rotatable chair frame. Background Art

[0002] Folding chairs are essential daily necessities. As a convenient and practical piece of furniture, folding chairs are also widely used outdoors. The characteristic of folding chairs is that they have a relatively small volume after folding, do not occupy much space, and are convenient for transportation. After being opened, they can be used normally.

[0003] For existing folding chairs, when the ground is uneven during outdoor camping, their stability decreases. The uneven ground will cause outdoor chairs to be unable to be placed stably, and they are prone to shaking or tilting. This will not only affect the comfort of users, but may also cause users to accidentally fall. Using outdoor chairs on uneven ground for a long time may cause damage to the structure of the chairs, such as deformation of the chair legs and loosening of the joints. Affect the use experience: The uneven ground will affect the normal use of outdoor chairs. Users may not be able to maintain a comfortable sitting position, reducing the user experience. Summary of the Invention

[0004] The problem to be solved by the utility model is how to overcome the above-mentioned defects that occur when the folding chair is used on uneven ground during outdoor camping.

[0005] To solve the above problems, the utility model provides a rotatable chair frame, which includes a central joint and a central tube. The central joint is used to install the central tube. An elastic pin is provided at one end of the central tube connected to the central joint. A limiting hole for cooperating with the elastic pin is opened on the central joint. The elastic pin moves in a circular motion along the edge inside the limiting hole, driving the central tube to rotate relative to the central joint.

[0006] After adopting the above structure, the central joint is used to connect with the central tube. Elastic pins are provided at the parts of both ends of the central tube inserted into the central joint. Limiting holes for cooperating with the elastic pins are also opened on the central joint. After the central tube is inserted into the central joint, its elastic pins cooperate with the limiting holes, allowing the elastic pins to move in a circular motion within a certain range along the edge of the limiting holes, thereby driving the central tube to rotate relative to the central joint. In this way, the movement of the elastic pins in the limiting holes realizes the rotational connection between the central tube and the central joint, solves the problem of different heights of outdoor ground, and keeps the chair frame stable.

[0007] Furthermore, there are multiple central joints. Both ends of the central tube are respectively inserted into multiple central joints, and the elastic pins respectively cooperate with the corresponding limiting holes.

[0008] After adopting the above structure, the user can rotate the two central joints of the folding chair to different positions on the left and right, so as to meet the usage requirements of different ground heights outdoors.

[0009] Further, the limiting holes opened on the central joint are arc-shaped.

[0010] Further, the limiting holes opened on the central joint are oval-shaped.

[0011] After adopting the above structure, the elastic pin is designed to provide a certain degree of elastic deformation in multiple directions. There is a limiting hole with an arc-shaped or oval-shaped on the central joint, and the size of the hole is large enough to allow the elastic pin to perform a certain range of circular motion along the edge of the hole inside it, thereby driving the central tube to rotate relative to the central joint. The user can rotate the central joint by an external force to rotate the central tube at a specific angle, thereby overcoming the defect of instability caused by different ground heights, so as to ensure the stability of the chair frame.

[0012] The beneficial effects of the present utility model adopting the above technical solutions include:

[0013] By setting a limiting hole on the central joint of the chair frame and an elastic pin on the central tube in the present utility model, after the central tube is inserted into the central joint, the elastic pin on it cooperates with the limiting hole, and the elastic pin performs a certain range of circular motion along the edge of the hole inside it, thereby driving the central tube to rotate relative to the central joint. When the outdoor camping ground is uneven, the user can adjust the angles of multiple chair legs in contact with the ground on the chair frame through this small range of rotation, so as to offset the height difference caused by different ground heights and maintain stability, so that the folding chair can also be used normally on uneven ground, improving the user experience.

[0020] To make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0021] The following are specific embodiments of the present utility model and, in conjunction with the accompanying drawings, further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments. Embodiment

[0022] This embodiment provides a rotatable chair frame, as Figures 1 to 4 shown, including a central joint 1 and a central tube 2. The central joint 1 is used to install the central tube 2. One end of the central tube 2 connected to the central joint 1 is provided with an elastic pin 201. The central joint 1 is provided with a limit hole 101 for cooperating with the elastic pin 201. The elastic pin 201 makes a circular motion along the edge inside the limit hole 101, driving the central tube 2 to rotate relative to the central joint 1.

[0023] Referring to Figure 2 and Figure 4 , specifically, an elastic pin 201 is provided at one end of the central tube 2 connected to the central joint 1. Allowing the central tube 2 to adapt to the change of the connection through the deformation of the elastic pin 201 when subjected to an external force. The central joint 1 is provided with a limit hole 101 that cooperates with the elastic pin 201. This limit hole 101 not only fixes the elastic pin 201 but also allows it to make a circular motion along the edge inside. This circular motion drives the rotation of the central tube 2 relative to the central joint 1.

[0024] Among them, there are multiple central joints 1. Both ends of the central tube 2 are respectively inserted into multiple central joints 1, and the elastic pins 201 respectively cooperate with the corresponding limit holes 101.

[0025] Specifically, in order to enhance the stability of the chair frame and the smoothness of rotation, the case where there are multiple central joints 1 is also proposed. Both ends of the central tube 2 are respectively inserted into multiple central joints 1, and the limit holes 101 on each central joint 1 cooperate with the corresponding elastic pins 201. In this way, even when a large rotational force is applied to one side of the central joint, the overall stability of the chair frame can be maintained through the support of other central joints 1.

[0026] Referring to Figure 3 , among them, the limit hole 101 opened on the central joint 1 is arc - shaped or oval - shaped.

[0027] Specifically, in order to enable the elastic pin 201 to perform circular motion within the limit hole 101, two possible shapes of the limit hole are proposed: arc-shaped and elliptical. Both of these shapes provide sufficient space for the elastic pin 201 to move along its edge, thereby realizing the rotation of the central tube 2. At the same time, they also limit the movement range of the elastic pin 201 to ensure the stability and controllability of the chair frame during rotation.

[0028] Specifically, the rotation function of the chair frame is realized: through the cooperation of the elastic pin 201 at one end of the central tube 2 and the limit hole 101 opened on the central joint 1, the central tube 2 can rotate relative to the central joint 1 under the action of an external force. It provides a more flexible and comfortable seat adjustment method for users. Especially in occasions where the seat direction or angle needs to be frequently adjusted, it can significantly improve the user experience.

[0029] Specifically, the stability of the chair frame is enhanced: a design with multiple central joints 1 is proposed. Both ends of the central tube 2 are inserted into multiple central joints 1 respectively, and are matched with the corresponding limit holes 101 through elastic pins 201. This multi-point support design can disperse the stress and deformation generated during the rotation of the chair frame, thereby enhancing the overall stability of the chair frame. Even after being subjected to a large external force or long-term use, the chair frame can maintain good structural integrity and performance.

[0030] Specifically, the smoothness of rotation is improved: by reasonably designing the shape of the limit hole 101, such as arc-shaped or elliptical, sufficient space is provided for the elastic pin 201 to perform circular motion. The friction and resistance during rotation are reduced, making the rotation of the central tube 2 smoother and more stable. At the same time, the shape of the limit hole 101 also limits the movement range of the elastic pin 201, avoiding structural damage or safety hazards caused by excessive rotation.

[0031] Specifically, the structure of the chair frame is simplified: the rotation function of the chair frame is realized through the simple cooperation of the elastic pin 201 and the limit hole 101, without complex mechanical transmission devices or electronic control systems. It not only reduces the production cost and manufacturing difficulty of the chair frame, but also improves its reliability and durability. At the same time, it is also convenient for users to perform maintenance and upkeep during use. The above functions together improve the performance and user experience of the chair frame.

[0032] Specifically, in scenarios where the ground is uneven, such as outdoor camping, users can slightly adjust the angle of the chair frame so that the chair legs can better adapt to the height difference of the ground. Since the elastic pin 201 of the central tube 2 is rotatably connected to the limit hole 101 on the central joint 1, users can easily adjust the angle of the chair frame within a certain range without complex operations or carrying additional tools. This design not only improves the performance of the folding chair on uneven ground but also enhances the user experience. Users can flexibly adjust the angle of the chair frame according to the actual situation to ensure the stability and comfort of the chair, thus enjoying the fun of outdoor camping more. It provides convenience and comfort for the use of folding chairs in scenarios such as outdoor camping. Users can also disassemble the chair frame by pressing the elastic pin, which is convenient and easy to operate.

[0033] In the present utility model, a limit hole is provided on the central joint of the chair frame, and an elastic pin is provided on the central tube. After the central tube is inserted into the central joint, the elastic pin on it cooperates with the limit hole, and the elastic pin makes a circular motion within a certain range along the edge of the hole inside, thereby driving the central tube to rotate relative to the central joint. When the ground is uneven during outdoor camping, users can adjust the angles of multiple chair legs in contact with the ground on the chair frame through this small range of rotation, so as to offset the height difference caused by the uneven ground height, maintain stability, and enable the folding chair to be used normally on uneven ground, enhancing the user experience.

[0034] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present utility model.
