Description

Technical Field

[0001] The utility model relates to the technical field of folding stools, in particular to an aluminum alloy folding stool. Background Art

[0002] The special aluminum alloy folding stool for ships, as a special seat or sitting tool on ships, is mainly characterized by being made of aluminum alloy material. Aluminum alloy has been widely used in shipbuilding due to its excellent properties, such as low density, light weight, high strength, good corrosion resistance, etc.

[0003] At present, most of the existing folding stools only rely on simple anti-slip pads or texture designs at the bottom to provide basic anti-slip effects. However, on wet, smooth or inclined surfaces, especially when used on the ship deck, these simple anti-slip measures are often difficult to effectively prevent the folding stool from sliding or shifting. In view of this, we propose an aluminum alloy folding stool. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an aluminum alloy folding stool, which can solve the problems raised in the above background art.

[0005] To achieve the above purpose, an aluminum alloy folding stool proposed by the utility model includes a base. A suction cup is fixedly connected to the outer wall of the base. When a force is applied to the suction cup, a sealed space can be formed between the suction cup and the ship's surface. At this time, external air cannot enter the inside of the suction cup. This pressure difference causes the suction cup to generate a strong adsorption force on the object surface, tightly adsorbing the object on the suction cup. A frame body is provided above the base, and a cushion is provided on the frame body. The base and the frame body are connected by a connecting mechanism, and the connecting mechanism includes:

[0006] The first support rod, the first support rod is hinged to the inner wall of the base, and a sliding groove is opened on the first support rod;

[0007] The second support rod, the second support rod is penetrated by the first support rod and is slidably connected to the first support rod. A clamping groove is opened on the side wall of the second support rod, and a notch is opened on the outer wall of the second support rod;

[0008] The sliding block, the sliding block is hinged to the second support rod.

[0009] Preferably, a sliding groove is opened on the frame body, a groove is opened on the inner wall of the sliding groove, and the sliding groove is slidably connected to the sliding block.

[0010] Preferably, the sliding block is penetrated by a limiting rod and is slidably connected to the limiting rod. One end of a second spring is fixedly connected to the outer wall of the limiting rod, and the other end of the second spring is fixedly connected to the inner wall of the sliding block.

[0011] Preferably, a sliding rod is fixedly connected to the outer wall of the seat cushion. By pressing the sliding rod on the surface of the sliding block, the sliding rod can limit the position of the limiting rod, so that the limiting rod is tightly stuck inside the groove, thereby improving the stability of the folding stool. The sliding rod is slidably connected to the inner wall of the frame body. A third spring is fixedly connected to the outer wall of the sliding rod, and the end of the third spring away from the sliding rod is fixedly connected to the inner wall of the frame body.

[0012] Preferably, a clamping rod is slidably connected to the first support rod. A first spring is fixedly connected to the outer wall of the clamping rod, and the end of the first spring away from the clamping rod is fixedly connected to the inner wall of the first support rod.

[0013] Preferably, a hinge rod is hinged to the outer wall of the clamping rod. A sliding rod is hinged to the end of the hinge rod away from the clamping rod. The sliding rod is slidably connected to the inner wall of the first support rod. The sliding rod is penetrated by a bolt and is threadedly connected to the bolt. The bolt is sleeved with the notch and the sliding groove. By screwing the bolt, the friction between the bolt and the second support rod is increased, thereby realizing the limitation of the sliding rod.

[0014] The utility model provides an aluminum alloy folding stool, which has the following beneficial effects:

[0015] (1) For this aluminum alloy folding stool, a suction cup is arranged on the outer wall of the base. When the folding stool is placed on a smooth or easily shaken surface such as a ship's hull, the suction cup can closely fit the surface under pressure to form a sealed space, effectively preventing the folding stool from sliding or shifting due to external environmental changes and enhancing the stability of use.

[0016] (2) For this aluminum alloy folding stool, through the design of the third spring between the seat cushion and the frame body, when a person sits on the folding stool, the downward pressure received by the seat cushion is transmitted to the sliding block through the sliding rod, thereby enhancing the clamping force between the limiting rod and the groove, further improving the stability of the folding stool in the dynamic use scenario and making the folding stool more stable when dealing with external shaking.

[0030] Furthermore, the frame 4 is provided with a sliding groove 41, the inner wall of the sliding groove 41 is provided with a groove 42, the sliding groove 41 is slidably connected with the sliding block 33, the sliding block 33 is penetrated by a limiting rod 331 and is slidably connected to the limiting rod 331, one end of a second spring 332 is fixedly connected to the outer wall of the limiting rod 331, the other end of the second spring 332 is fixedly connected to the inner wall of the sliding block 33, one end of a sliding rod 51 is fixedly connected to the outer wall of the seat cushion 5, the sliding rod 51 is slidably connected to the inner wall of the frame 4, one end of a third spring 52 is fixedly connected to the outer wall of the sliding rod 51, the other end of the third spring 52 away from the sliding rod 51 is fixedly connected to the inner wall of the frame 4;

[0031] In the present utility model, when using the folding stool, hold the frame 4 with both hands and lift it upward. Under the action of force, the first support rod 31 and the second support rod 32 will rotate around the hinge point of the first support rod 31. At the same time, during this process, the sliding block 33 will slide in the sliding groove 41. During the sliding process of the sliding block 33, the groove 42 will squeeze the limiting rod 331, so that the limiting rod 331 completely enters the inside of the sliding block 33, and at the same time, the second spring 332 undergoes elastic deformation.

When the sliding rod 51 presses against the outer wall of the sliding block 33, at this time, the sliding rod 51 will limit the limiting rod 331, so that the limiting rod 331 is tightly clamped inside the groove 42, thereby improving the stability of the folding stool. At the same time, the suction cup 2 will be closely attached to the surface of the hull under the action of pressure, so that a sealed space is formed between the suction cup 2 and the surface of the hull, thereby improving the stability of the folding stool and preventing the folding stool from moving due to the shaking of the hull;

[0032] When the height of the folding stool needs to be adjusted, step on the base 1 with the foot, and then pull the frame 4 upward. At this time, the card slot 321 will exert a force on the card rod 313, causing the card rod 313 to completely enter the first support rod 31. At the same time, the first spring 314 undergoes elastic deformation. When the folding stool is adjusted to the appropriate height, the card rod 313 will coincide with the card slot 321. At this time, the card rod 313 will be re-engaged in the card slot 321 under the elastic force of the first spring 314. Then, turn the bolt 312 to limit the sliding rod 316, thereby preventing the card rod 313 from returning to the inside of the first support rod 31 under the action of pressure.

[0033] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
