[0065] The waterproof outer bag 1 and the plurality of support plates 2 constitute an inflation-free pool, and the shape of the waterproof outer bag 1 is controlled by the plurality of support plates 2 .

[0066] In the present technical solution, a plurality of support plates 2 and a waterproof outer bag 1 can form an elliptical pool structure.

[0067] In addition, the plurality of support plates 2 and the waterproof outer bag 1 may also form other shapes, not limited to the elliptical structure.

[0068] The inclined support member 3 includes a rotating shaft 31, and a receiving groove is provided on the outer side of the support plate 2, and the rotating shaft 31 is rotatably connected to the side wall of the receiving groove;

[0069] An adjusting member 32 is connected to one side of the rotating shaft 31 , and one end of the adjusting member 32 away from the rotating shaft 31 is rotatably connected to the anti-slip foot 33 .

[0070] In this technical solution, the inclined support member 3 can be used to support the pool.

[0071] The adjusting member 32 includes a fixed sleeve 321 and a rotating stud 322, and one end of the fixed sleeve 321 is connected to the outer side of the rotating shaft 31;

[0072] The other end of the fixing sleeve 321 is threadedly connected to the rotating stud 322 , and one end of the rotating stud 322 away from the fixing sleeve 321 is rotatably connected to one side of the anti-slip foot 33 .

[0073] In the present technical solution, the length of the oblique support member 3 can be adaptively adjusted by utilizing the adjusting member 32 .

[0074] The anti-slip foot 33 includes a central sleeve 331, and the upper side of the central sleeve 331 is rotatably connected to one end of the rotating stud 322;

[0076] One end of the sliding column 333 away from the anti-slip plate 332 is connected to the auxiliary support leg 334 .

[0077] In the present technical solution, the anti-slip feet 33 can be used to increase the contact area with the ground, thereby increasing the stability of the inclined support member 3 during support.

[0078] The opposite sides of the two anti-slip plates 332 are connected by an elastic member 335 , and the elastic member 335 is arranged in the inner cavity of the central sleeve 331 .

[0079] In the technical solution, the elastic member 335 is used to make the auxiliary legs 334 on both sides move automatically to opposite directions when they are away from the supporting plate 2.

[0080] When in use, the oblique support member 3 is rotated, and the adjustment member 32 and the anti-skid support foot 33 are rotated out of the support plate 2. Then, according to the terrain, the rotating stud 322 is rotated, thereby driving the rotating stud 322 to move in the fixed sleeve 321, and the length of the adjustment member 32 is adjusted, thereby adjusting the position of the anti-skid support foot 33.

[0081] When the anti-slip support foot 33 rotates out of the support plate 2, under the action of the elastic member 335, the anti-slip plates 332, sliding columns 333 and auxiliary support feet 334 on both sides move in opposite directions, that is, the auxiliary support feet 334 on both sides move away from the center sleeve 331, and then the auxiliary support feet 334 on both sides and the center sleeve 331 are used to contact the ground to support the support plate 2, thereby expanding the contact area between the inclined support member 3 and the ground, making the support of the inclined support member 3 more stable.

[0082] The auxiliary member 4 includes a connecting belt 41 and a sleeve ring belt 42. A plurality of connecting belts 41 are connected to the bottom of the waterproof outer bag 1. The number of the connecting belts 41 is the same as the number of the oblique supporting members 3.

[0084] In the present technical solution, the auxiliary member 4 can be used to further increase the stability of the inclined support member 3, thereby increasing the stability of the pool.

[0085] After the position of the inclined support member 3 is adjusted, the connecting belt 41 and the sleeve ring belt 42 are pulled, and then the two sleeve ring belts 42 are respectively sleeved on the sliding column 333, so that the inclined support member 3, the auxiliary member 4 and the support plate 2 can form a triangular support, thereby increasing the stability of the pool structure.

[0086] The anti-drop assembly 5 includes an elastic member 51 and an anti-slip plate 52, and the elastic member 51 is connected to the bottom of the storage groove of the support plate 2;

[0087] The upper end of the second elastic member 51 is connected to the bottom of the anti-slip plate 52 .

[0088] In the present technical solution, the anti-drop assembly 5 can be used to prevent the diagonal support member 3 from falling out of the support plate 2 when being stored, thereby increasing the stability of the diagonal support member 3 when being stored.

[0089] Anti-deflection columns 53 are connected to both sides of the anti-slide plate 52, and the anti-deflection columns 53 are slidably connected to the side surfaces of the storage slot.

[0090] In the present technical solution, the anti-deflection column 53 can be used to limit the moving trajectory of the anti-slide plate 52 to prevent the anti-slide plate 52 from sliding out of the storage groove.

[0091] When the pool is stored, the diagonal support member 3 is stored in the support plate 2. At this time, under the action of the elastic member 2 51, the anti-slip plate 52 is tightly attached to the bottom of the anti-slip support foot 33 to prevent the diagonal support member 3 from accidentally falling out of the support plate 2, thereby increasing the stability of the diagonal support member 3 when stored.

[0092] A reinforcing assembly 6 is provided above the oblique supporting member 3, and the reinforcing assembly 6 is connected to the supporting plate 2 and the waterproof outer bag 1 respectively;

[0093] The reinforcing assembly 6 includes two connecting columns 61, and the two connecting columns 61 are respectively connected to two ends of the rotating shaft 31;

[0094] The end of the connecting column 61 away from the rotating shaft 31 is connected to a rotating gear 62, and a locking rack 63 is arranged above the rotating gear 62. The locking rack 63 and the rotating gear 62 are locked when they are in contact with each other;

[0096] The top of the engaging rack 63 is connected with an elastic member 3 66 , and the elastic member 3 66 is installed on the inner side of the supporting plate 2 .

[0097] In the present technical solution, the reinforcing component 6 is used to lock the inclination angle of the oblique support member 3 when there is water or heavy objects such as a human body in the waterproof outer bag 1, thereby increasing the stability of the support of the oblique support member 3.

[0098] When the rotating shaft 31 rotates, the connecting column 61 and the rotating gear 62 can be driven to rotate. When the rotating shaft 31 is adjusted, water is added to the waterproof outer bag 1. When there are heavy objects such as water in the pool, the pressure plate 65 is pressed downward under the gravity of the water and other heavy objects, thereby driving the L-shaped frame 64 and the engaging rack 63 to move downward, so that the engaging rack 63 and the top of the rotating gear 62 are attached and engaged, thereby locking the angle of the engaging rack 63, and then locking the angle of the rotating shaft 31, that is, the angle of the oblique support member 3 can be locked, thereby further increasing the stability of the support of the oblique support member 3, making the pool more stable when in use;

[0099] When the force on the pressure plate 65 disappears, under the action of the elastic member 3 66, the engaging rack 63 moves away from the rotating gear 62 and returns to the initial position, and the rotating gear 62 and other structures can continue to rotate.
