Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the present invention, the terms "upper", "lower", "left", "right", "middle" and "one" are used for clarity of description, but not for limiting the range of the present invention, and the relative relationship changes or adjustments without substantial technical changes should be regarded as the scope of the present invention.

Referring to fig. 1-2, a folding seat of an inflatable boat comprises a base 1, a driving shaft 10 is rotatably connected in the base 1, two groups of sealed cavities 2 are arranged in the base 1, the number of the sealed cavities 2 in each group is two, each group of sealed cavities 2 is respectively positioned at two sides of the driving shaft 10, so that four corners of the base 1 are hinged with the sealed cavities 2, when the sealed cavities 2 are perpendicular to the base 1, a more stable supporting seat cushion 16 can be achieved, sealing plugs 9 are slidably connected in the sealed cavities 2, sliding blocks 3 are slidably connected in the sealed cavities 2, two oil through holes are respectively arranged on the sliding blocks 3, the sliding blocks 3 are fixedly connected with supporting rods 8, wherein one end of each supporting rod 8 penetrates through the sealed cavity 2 and is fixedly connected with a push block 7, a piston 4 is fixedly connected on the supporting rod 8, a spring 5 is fixedly connected on the piston 4, one end of the spring 5, far away from the piston 4, is fixedly connected on the sealed cavity 2, therefore, when the seat is folded, after the seat reaches the manual valve on the air release pipe 14, when the sealing plug 9 is not extruded by gas, the piston 4 is pushed to move and reset through the elasticity of the spring 5, and the support rod 8 and the slide block 3 move downwards, and because the flow rate of hydraulic oil in the oil through hole on the slide block 3 is low, the buffer effect on the slide block 3 and the support rod 8 is achieved, the air release pipe 14 is arranged on the sealing cavity 2, and the manual valve is arranged on the air release pipe 14.

Be equipped with the atmospheric pressure part on the drive shaft 10, the atmospheric pressure part is including closed chamber 12, closed chamber 12 fixed connection is on base 1, reciprocal screw thread has been seted up on the drive shaft 10, threaded connection has closed stopper 13 on the drive shaft 10, closed stopper 13 sliding connection is in closed chamber 12, fixed intercommunication has two intake pipe 6 on the closed chamber 12, be equipped with the check valve on the intake pipe 6, fixed intercommunication has gas-supply pipe 17 between closed chamber 12 and the sealed chamber 2, be equipped with the check valve on the gas-supply pipe 17, consequently, when drive shaft 10 rotates, reach closed stopper 13 and do reciprocating sliding motion in closed chamber 12, thereby reach and inhale air through intake pipe 6, it breathes in to reach through gas-supply pipe 17, reach the rising that promotes bracing piece 8 and ejector pad 7.

The screw thread has all been seted up at drive shaft 10 both ends, there is stopper 11 at drive shaft 10 both ends difference threaded connection, stopper 11 both ends are located 2 downside in sealed chamber respectively, when drive shaft 10 rotates, threaded connection keeps away from sealed chamber 12 at the stopper 11 on drive shaft 10, consequently, through stopper 11's removal, thereby be the vertical state with 2 promotion in sealed chamber of slope with base 1, thereby reach and to stably support and play seatpad 16 and rise, fixedly connected with expansion plate 15 on the base 1, base 1's one end fixedly connected with seatpad 16 is kept away from to expansion plate 15, seatpad 16 sets up because expansion plate 15 has flexible effect at the upside of ejector pad 7, thereby be favorable to the folding effect of seat, simultaneously can be stable support seatpad 16.

In the novel use, the driving shaft 10 is rotated, the sealing plug 13 is in threaded connection with the reciprocating threads on the driving shaft 10, so that the sealing plug 13 slides in a reciprocating manner in the sealing cavity 12 under the rotation of the driving shaft 10, when the sealing plug 13 moves rightwards, the one-way valve on the air pipe 17 is closed, the one-way valve on the air pipe 6 is opened, the air pressure in the sealing cavity 12 is reduced, air is sucked through the air pipe 6, when the sealing plug 13 moves leftwards, the one-way valve on the air pipe 6 is closed, the one-way valve on the air pipe 17 is opened, air is extruded through the movement of the sealing plug 13, the air in the sealing cavity 12 enters the sealing cavity 2 through the air pipe 17, the sealing plug 9 is extruded to move through the continuous increase of the air in the sealing cavity 2, as the hydraulic oil is arranged between the sealing plug 9 and the piston 4, the hydraulic oil is extruded through the movement of the sealing plug 9 to push the piston 4 to move through the oil through the sliding hole on the sliding block 3, thereby achieving the movement of the supporting rod 8 and the pushing block 7 far away from the sealing cavity 2.

Simultaneously because drive shaft 10's rotation for the stopper 11 of threaded connection on drive shaft 10 keeps away from respectively and seals chamber 12, because stopper 11's removal, thereby extrude sealed chamber 2, because sealed chamber 2 one end articulates on base 1, thereby under stopper 11's extrusion, reach with base 1 vertical state from the tilt state, simultaneously because the shifting up of bracing piece 8 and ejector pad 7, reach and promote seatpad 16, because seatpad 16 passes through expansion plate 15 fixed connection on base 1, thereby reach the rise of seatpad 16, make the seat after extending, can accomplish stable support and use.

When the air-tight sealing structure is folded, the manual valve on the air release pipe 14 is opened, so that the air in the sealing cavity 2 is discharged through the air release pipe 14, when the sealing plug 9 is not extruded by the air, the piston 4 is pushed by the elastic force of the spring 5 to move and reset, and the support rod 8 and the sliding block 3 move downwards, and the flow speed of hydraulic oil in the oil through hole in the sliding block 3 is slow, so that the buffer effect on the sliding block 3 and the support rod 8 is achieved, and the slow descending of the seat cushion 16 can be achieved.

In the present application, the terms "mounted," "connected," and "secured" are to be construed broadly unless otherwise specifically indicated and limited.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
