Specifically, the support assembly 4 is located on an outer side of the annular surrounding wall 2. The pool liner 3 can be fixed on an inner side of the annular surrounding wall 2 and forms a water storage space. The pool liner 3 usually covers the inner side of the overall annular surrounding wall 2 and a bottom surface of the annular surrounding wall 2. An upper edge of the pool liner 3 may be folded and supported by an upper edge of the annular surrounding wall 2. At the position where the upper edge of the pool liner 3 is folded and propped, a clamping member, including a downward-facing groove, fixedly clamps the upper edge of the pool liner 3 and the upper edge of the annular surrounding wall 2. The pool liner 3 may be a waterproof, flexible material. After the upper edge of the pool liner is folded, supported by the upper edge of the annular surrounding wall 2, and fixedly clamped, the shape and size of the bottom of the pool liner 3 may substantially match the shape and size enclosed by the annular surrounding wall 2. A structure of the clamping member may be analogous to the slot-type clamping strip described in Chinese Patent Publication No. CN 203879057 U and/or to the clamping strip in Chinese Patent Publication No. CN 205348866 U.

During assembly, a lower edge of the annular surrounding wall 2 is joined to the annular base 1. The annular base 1 may be provided with an upward-facing groove (not shown). The lower edge of the annular surrounding wall 2 is inserted into the upward groove, to enable the shape of the annular surrounding wall to adapt to the shape of the annular base. As the water storage space is filled, pressure is generated on the inner side of the annular surrounding wall 2, to cause a deformation of the annular surrounding wall 2. To mitigate or eliminate this deformation, the support assembly 4 may be disposed on the outer side of the annular surrounding wall 2.


Specifically, as shown in FIG. 4, the support assembly 4 comprises a horizontal support member 41, a vertical support member 42, a first connecting member 43, and a second connecting member 44. The horizontal support member 41 covers the upper edge of the annular surrounding wall 2, and is connected to the vertical support member 42 by the first connecting member 43. The vertical support member 42 is connected to the annular base 1 by the second connecting member 44. More specifically, with reference to FIG. 5a to FIG. 6, the first connecting member 43 comprises a connecting member body 431 and a protective cover 432. A first insertion slot 4311 and a positioning post 4312 are respectively provided on two opposite sides of the connecting member body 431. The vertical support member 42 fits within the first insertion slot 4311, and is thereby connected to the connecting member body 431 from below the connecting member body 431. The horizontal support member 41 is attached to the positioning post 4312, and is thereby connected to the connecting member body 431 from above the connecting member body 431. As discussed above, the horizontal support member 41 covers the upper edge of the annular surrounding wall 2. Similarly, the connecting member body 431 covers the upper edge of the annular surrounding wall 2. According to an example aspect, a clamping member may be is disposed at the upper edge of the annular surrounding wall 2, and may comprise a downward groove that clamps the pool liner 3 at the annular surrounding wall 2. As shown in FIG. 5b, the connecting member body 431 comprises a first receiving groove 4313. The first receiving groove 4313 and the first insertion slot 4311 are located on the same side of the connecting member body 431. The first receiving groove 4313 is used for accommodating the upper edge of the annular surrounding wall 2, and may also accommodate a clamping member that is disposed at the upper edge of the annular surrounding wall 2 and is provided with a downward groove.


As can be seen, a top end of the vertical support member 42 is attached to the annular surrounding wall 2 by the connecting member body 431. The top end of the vertical support member 42 is inserted in the first insertion slot 4311 of the connecting member body 431, and the connecting member body 431 is thereby attached to the upper edge of the annular surrounding wall 2.


Further, a bottom end of the vertical support member 42 is attached to the annular surrounding wall 2 by the second connecting member 44. As shown in FIG. 6, the second connecting member 44 has a second insertion slot 441 and a second receiving groove 442 located on the same side as the second insertion slot 441. The vertical support member is connected to the second insertion slot 441 from above the second connecting member 44. The second receiving groove 442 accommodates the lower edge of the annular surrounding wall 2. With reference to FIG. 3, the second receiving groove 442 accommodates the annular base 1 and thereby holds the lower edge of the annular surrounding wall 2.


After the installation of the vertical support member 42 is completed, the first insertion slot 4311 of the first connecting member 43 and the second insertion slot 441 of the second connecting member 44 are arranged opposite each other and are used for respectively inserting the top end and lower end of the vertical support member 42. The shapes of the first insertion slot 4311 and the second insertion slot 441 may be adapted to a contour of the vertical support member 42. The vertical support member 42 may have a three-dimensional contour. For example, a cross section of the vertical support member 42 may approximate an arc with a plurality of bends, to enhance the structural strength of the vertical support member 42 in a support direction (vertical direction) of the vertical support member. Correspondingly, the first insertion slot 4311 and the second insertion slot 441 may be disposed as nonlinear through slots with a plurality of bends.


As discussed above, a prepositioning structure of the vertical support member 42 is described. The prepositioning structure of the horizontal support member 41 is described below in detail.


As shown in FIG. 7a to FIG. 8b, the connecting member body 431 of the first connecting member 43 includes the positioning post 4312 protruding from an upper side of the connecting member body 431. The positioning post 4312 is used for prepositioning end portions of two adjacent horizontal support members 41.

The horizontal support member 41 may have a width configured to support an object placed thereon. In an example aspect shown in FIG. 7a and FIG. 7b, four positioning posts 4312 are symmetrical two by two and are disposed at an angle with respect to each other, to thereby conform to an included angle between two adjacent horizontal support members 41. Correspondingly, an end portion of the horizontal support member 41 includes a through hole 411 configured to hold the positioning post 4312 therewithin. Each end portion of each horizontal support member 41 may include two through holes 411, and at least one of the two through holes 411 may be a slotted hole, to thereby enable adjustment of a joint position of the positioning post 4312 in the through hole 411, to eventually implement that the plurality of horizontal support members 41 are connected head to tail. According to another example embodiment, the shapes of the positioning post 4312 and the through hole 411 may adapt to each other, and for example, may each have a shape of a triangle, a square, or another polygon, to implement accurate prepositioning and stable connection. The quantities and positions of the positioning posts 4312 are not limited by the examples shown in the drawings.


The horizontal support member 41 is sleeved over the positioning post 4312 through the through hole 411 of the horizontal support member to thereby implement prepositioning. Every two adjacent connecting member bodies 431 support one horizontal support member 41. In addition, as shown in FIG. 8a to FIG. 8b, the first connecting member 43 includes the protective cover 432 which may limit the separation between the horizontal support member 41 and the positioning post 4312. The protective cover 432 and the connecting member body 431 coordinate to clamp the horizontal support member 41 therebetween. Optionally, a convex tooth 4321 may be provided on an inner side (a side facing the connecting member body 431) of the protective cover 432, and the convex tooth 4321 may be adapted to some or all of grooves 412 (as shown in FIG. 7a, the surface of the horizontal support member 41 is provided with a plurality of grooves 412) in the surface of the horizontal support member 41, to thereby limit a displacement of the horizontal support member 41.


According to an example embodiment, as shown in FIG. 7b and FIG. 8b, the connecting member body 431 may include a clamping tongue 4314. The protective cover 432 is provided with a clamping hook 4322. The clamping hook 4322 is joined to the clamping tongue 4314, such that, at one end the protective cover 432 is connected to the connecting member body 431, and at the other end, the protective cover 432 is connected to the connecting member body 431 by a threaded fastener, as shown in FIG. 5a. Alternatively, the protective cover 432 may be connected to the connecting member body 431 in a completely clamping manner.


According to an example embodiment, after the vertical support member 42 is inserted into the first connecting member 43 and the second connecting member 44, the vertical support member 42, and the first connecting member 43 and the second connecting member 44 can be further locked by threaded fasteners. Specifically, as shown in FIG. 5a and FIG. 8a, the connecting member body 431 may include a first connecting hole 4315. The top end of the vertical support member 42 may include a first mounting hole 421. When the vertical support member 42 is inserted into the bottom of the first insertion slot 4311, the first connecting hole 4315 and the first mounting hole 421 are aligned, and may then be connected by a threaded fastener. Similarly, as shown in FIG. 6, the second connecting member 44 may include a second connecting hole 443. The bottom end of the vertical support member 42 may include a second mounting hole 422. When the vertical support member 42 is inserted into the bottom of the second insertion slot 441, the second connecting hole 443 and the second mounting hole 422 are aligned, and may then be connected by a threaded fastener. However, when the first insertion slot 4311 and the second insertion slot 441 have sufficient depths, locking can be implemented without threaded fasteners.


The connecting member body 431 of the first connecting member 43 may be a single integral member which can enable prepositioning between the connecting member body 431 and the vertical support member 42 and the horizontal support member 41. Compared with the use of a plurality of bolt fasteners shown in FIG. 1 and FIG. 2, installation steps may be greatly simplified. Materials of the first connecting member 43 and/or the second connecting member 44 may be plastic. The connecting member body 431 and the protective cover 432 of the first connecting member 43 and/or the second connecting member 44 may be respectively formed in an injection molding manner, to achieve advantages of simple manufacturing and corrosion resistance.


Compared with an existing design, the first connecting member 43 and the second connecting member 44 according to one or more example embodiments may enable completion of the installation of the support assembly 4 in an efficient and economical manner.
