Technical Field

[0001] This utility model relates to the field of folding chair technology, specifically a folding chair. Background Technology

[0002] A folding chair is a chair that can be folded into a portable and movable form.

[0003] Based on the above, the inventor discovered that: Currently, there are many folding chairs on the market, but in general folding chairs, after the supporting legs are unfolded and placed, the person sitting on the chair shakes violently, which easily causes the two supporting legs to slide on the ground. This results in poor support for the user and makes it difficult for the user to rest their head on the chair, thus making the chair too limited and reducing the effectiveness of the device. Therefore, in view of this, the inventor has researched and improved the existing structure to provide a folding chair with greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a folding chair, including a pad, an inclined leg that rotates on the outer wall of the pad, two pivots that rotate on the inner wall of the inclined leg, a support leg fixed on the outer wall of the two pivots, a limiting mechanism on the outer wall of the inclined leg, and an adjustment mechanism on the outer wall of the inclined leg.

[0006] The limiting mechanism includes:

[0007] Four connecting columns, one end of each connecting column is fixed to one end of the rotating shaft, and a perforated plate is fixed to the outer wall of each of the four connecting columns. One side of each of the four perforated plates slides against the outer wall of the inclined leg. Two horizontal columns are fitted onto the inner wall of each of the four perforated plates. Two round holes are opened on the outer wall of the inclined leg, and the inner walls of the two round holes are matched with the outer walls of the horizontal columns.

[0008] As a preferred embodiment of this utility model, guardrails are provided on both sides of the pad, and one side of each guardrail is fixed to the outer wall of the inclined leg.

[0009] As a preferred embodiment of this utility model, the inner wall of the inclined leg is fitted with two connecting rods, and the bottom ends of the two connecting rods are fixed with suction cups.

[0010] As a preferred embodiment of this utility model, both ends of the two circular holes are provided with groove blocks, and one end of each of the four groove blocks is provided on the outer wall of the inclined leg.

[0011] As a preferred embodiment of this utility model, the adjusting mechanism includes:

[0012] A cushion, one side of which slides against the outer wall of the inclined leg, a screw is fixed to the top of the cushion, the outer wall of the screw is fitted with the inner wall of the inclined leg, the outer wall of the inclined leg is provided with a ring, and the inner wall of the ring is threaded with the outer wall of the screw.

[0013] As a preferred embodiment of this utility model, two sliders are fixed on both sides of the cushion, and two grooves are formed on the outer wall of the inclined leg, with the inner walls of the two grooves sliding against the outer walls of the sliders.

[0014] As a preferred embodiment of this utility model, the inner walls of both sliding grooves are fixed with sliding rods, and the outer walls of both sliding rods slide against the inner walls of the slider.

[0015] The beneficial effects of this utility model are:

[0016] 1. This solution controls the swaying of the inclined leg and the pad to keep the pad level with the ground. Then, the support leg drives the rotating shaft to rotate on the inner wall of the inclined leg, keeping the bottom of the support leg and the bottom of the inclined leg level. At the same time, the perforated plate fixed to the rotating shaft is driven by the connecting column to slide on the outer wall of the inclined leg. The outer wall of the horizontal column is fitted with the inner wall of the perforated plate, so that the outer wall of the horizontal column and the inner wall of the round hole are engaged. The inner wall of the groove block is matched with the outer wall of the horizontal column, thus securing the support leg and the inclined leg for better support of the pad. The outer wall of the connecting column is fitted with the inner wall of the inclined leg, so that the suction cup fixed to the connecting rod is firmly installed on the ground. This makes it easier to place the device more stably on the ground and prevents the support leg and the inclined leg from sliding on the ground due to external forces. This makes it easier for users to sit on the pad and improves the practicality of the device.

[0017] 2. This solution controls the screw to be fitted onto the inner wall of the inclined leg, thereby driving the cushion to slide on the outer wall of the inclined plate. Simultaneously, the slider slides on the inner wall of the groove and the outer wall of the slide rod until the cushion is moved to the user's head. The inner wall of the ring and the inner wall of the screw are threaded together, allowing the user's head to be positioned stably on the cushion under downward pressure. This allows the cushion to slide on the outer wall of the inclined leg according to the user's head height in the chair, thus providing better head support and effectively improving the device's practicality.
