[0055] In one embodiment, as shown in Figure 4 , the cover 1 comprises a stool connecting part 11 and an umbrella connecting part 12;
[0056] The edge of the stool connecting part 11 is connected with the support assembly 3, and the inside of the stool connecting part 11 is provided with a cavity;
[0057] The umbrella connecting part 12 is connected with the cavity, and the umbrella connecting part 12 is placed in the cavity after being folded.
[0058] The seat connecting part 11 is provided with a cavity, and the cavity is provided with an opening. The cavity functions as a bag. The center part of the umbrella connecting part 12 is fixed to the inner wall of the cavity. The umbrella connecting part 12 is folded from the edge to the center. After folding, the seat connecting part 11 covers the folded part of the umbrella from the opening, until the folded part of the umbrella is completely covered. The opening is provided with a sealing element for sealing.
[0059] Further, as shown in Figure 4 , the inner surface of the umbrella connecting part 12 is provided with a fixing buckle 121. The fixing buckle 121 is adapted to the fixing element 22. The fixing buckle 121 and the connecting assembly 2 are detachably connected.
[0060] In one specific embodiment, as shown in Figure 2 , 5 -8, the connecting assembly 2 comprises a sleeve 21 and a fixing element 22. The sleeve 21 is sleeved outside the fixing element 22. The fixing element 22 can slide along the axial direction of the sleeve 21. The end of the fixing element 22 away from the sleeve 21 is connected to the cover 1.
[0061] Further, as shown in Figure 7 , 8 , the fixing element 22 comprises two dispersion rods 221 and a hinge joint 222. The two dispersion rods 221 are respectively hinged to the hinge joint 222. The hinge joint is connected with a spring.
[0062] When the connecting assembly 2 is in an extended state, the dispersion rods 221 are spread outward from the hinge joint 222. When the connecting assembly 2 is in a contracted state, the spring is contracted, and the dispersion rods 221 are combined and collected in the sleeve 21.
[0063] The dispersion rods 221 are connected to the umbrella connecting part 12 at multiple points, so that the connection between them is more firm, and the effect of the connecting assembly 2 on the umbrella connecting part 12 is better.
[0064] Alternatively, as shown in Figure 3 , the fixing element 22 is a connecting rod.
[0065] Further, as shown in Figure 6 , a linkage 23 is provided between the multiple connecting assemblies 2. When one connecting assembly 2 rotates, the remaining connecting assemblies 2 rotate synchronously under the drive of the linkage 23.
[0066] The linkage 23 comprises bevel gears 232, a rotating shaft 231 is arranged between each connecting assembly 2 and the supporting assembly 3, two bevel gears 232 are arranged between two adjacent rotating shafts 231, and the two bevel gears 232 are connected with the two rotating shafts 231 respectively and mesh with each other. When one connecting assembly 2 rotates, the rotating shaft 231 drives the bevel gears 232 to rotate, and the two bevel gears 232 mesh to drive the adjacent connecting assembly 2 to rotate synchronously, so that the rotation is synchronous, and the same connection position is ensured when the cover 1 is connected, which is beneficial to uniform stress.
[0067] Further, as shown in Figure 5 The connecting assembly 2 and the supporting assembly 3 are provided with a rotating adjusting member 24, and the rotating adjusting member 24 comprises a clamping gear 241 and a push piece 242.
[0068] The clamping gear 241 is fixedly connected with the connecting assembly 2 and rotates with the connecting assembly 2, and the clamping gear 241 is provided with arc-shaped teeth in the reverse direction of the rotating direction.
[0069] The supporting assembly 3 is provided with a movable channel 243, and the push piece 242 is arranged in the movable channel 243. One end of the push piece 242 is connected with an elastic member 245, and the other end is clamped with the clamping gear 241, so that the connecting assembly 2 can only rotate away from the supporting assembly 3. The push piece 242 is provided with a reset key 244, and moving the reset key 244 can drive the push piece 242 to compress the elastic member 245.
[0070] The teeth of the clamping gear 241 can be provided with six teeth according to the use state. Since the rotating angle is only in the range of 0°-180° during use, only three teeth cooperate with the push piece 242 during rotation, that is, the connecting assembly 2 has three gears. When the connecting assembly 2 rotates away from the supporting assembly 3 from the storage state, the push piece 242 gradually contacts the arc surface with the rotation of the clamping gear 241 from the first tooth groove. When the rotating angle in the acute angle range reaches the set angle, the push piece 242 contacts the second tooth groove of the clamping gear 241. At this time, the push piece 242 and the tooth groove are clamped. At this time, if the connecting assembly 2 reverses, the tooth groove will be clamped by the push piece 242, so that the connecting assembly 2 cannot rotate towards the supporting assembly 3. When it is needed to rotate to the obtuse angle state, it can continue to rotate away from the supporting assembly 3. After rotating to the obtuse angle state, the card is clamped with the tooth groove of the third tooth. If it is desired to rotate towards the supporting assembly 3, the reset key 244 needs to be forced, so that the push piece 242 compresses the elastic member 245 and moves away from the clamping gear 241. At this time, the clamping gear 241 will not be blocked by the push piece 242, so that it can rotate towards the supporting assembly 3.
[0071] In a specific embodiment, as shown in Figure 3As shown, the outdoor stool also has a storage state, when in the storage state, the connecting assembly 2 is rotated to be attached to the support leg 32, the support leg 32 is in a retracted state, and the connecting assembly 2 and the support assembly 3 are collectively stored in the cavity.
[0072] The initial state is the storage state, when the outdoor stool is used, the connecting assembly 2 is rotated to an acute angle, the cover 1 is connected to the connecting assembly 2, and the support assembly 3 is extended to be the outdoor stool; when the umbrella is used, the connecting assembly 2 is extended, the connecting assembly 2 is rotated to an obtuse angle state, and the cover 1 is connected to the connecting assembly 2 after being unfolded to be the umbrella.
[0073] The places not mentioned in the present application can be realized by using or referring to the existing technology.
[0074] Each of the embodiments in the specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment mainly explains the difference from other embodiments.
[0075] The above only describes the embodiments of the present application and is not used to limit the present application. The present application can have various changes and modifications for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the scope of claims of the present application.
