The mating surface 202 may be configured as a plane with a fixed inclination angle, where the portions of the first standing structure 101 and the second standing structure 102 that contact the mating surface 202 maintain the same inclination angle. Alternatively, two mating surfaces 202 may be provided, with two mating surfaces 202 being disposed adjacent to each other, with a protruding edge formed between the two mating surfaces 202. It will be appreciated that when the inclination angles of the two mating surfaces 202 are the same, the two mating surfaces 202 are symmetrical about the edge, and that the inclination angles of the two mating surfaces 202 may also differ under certain requirements.

In some examples, the ends of the first water standing structure 101 and the second water standing structure 102 each include a docking unit 103 and a matching unit 104, when the docking units 103 are abutted against each other, the first water standing structure 101 and the second water standing structure 102 are docked at an angle, and it is understood that the angle of the docking unit 103 determines the angulation of the first water standing structure 101 and the second water standing structure 102, and may be set according to specific requirements.

Further, the inclination angle of the mating unit 104 can be set according to the inclination angle of the corresponding mating surface 202, and the mating unit 104 and the mating surface 202 are abutted against each other, so as to complete the preliminary connection of the first standing structure 101, the second standing structure 102 and the supporting leg 201.

The docking unit 103 is disposed above the matching unit 104, that is, the upper half parts of the ends of the first water standing structure 101 and the second water standing structure 102 are used for being connected with each other, and the lower half parts of the ends of the first water standing structure 101 and the second water standing structure 102 are used for being connected with the supporting legs 201, so that the first water standing structure 101, the second water standing structure 102 and the supporting legs 201 are guaranteed to be connected in pairs at the same time, and the connection stability of the water standing assembly is improved.

As shown in fig. 6, the first standing water structure 101, the second standing water structure 102 and the supporting leg 201 are all connected with the connecting unit 301 by fasteners, which is equivalent to further connecting the first standing water structure 101, the second standing water structure 102 and the supporting leg 201 by fasteners, and combining the mortise and tenon connection with the fastener connection.

The connection unit 301 is abutted with the supporting leg 201, the first standing water structure 101, and the second standing water structure 102 with a large contact area, and the fastening members are mounted when the positions are stable.

In some examples, the end of the supporting leg 201 is provided with a tenon 203, the tenon 203 is approximately at a near point corresponding to a far point, it is understood that the tenon 203 protrudes from the end of the supporting leg 201, and the first water standing structure 101, the second water standing structure 102 and the connection unit 301 are in contact fit with the tenon 203, so that the contact area between the structures is increased.

Further, the first water standing structure 101, the second water standing structure 102 and the connecting unit 301 are arranged around and hold the tenon 203, so that the positions of the structures relative to the tenon 203 are stable, i.e. the positions of the structures relative to the supporting legs 201 are stable.

As shown in fig. 7 and 8, in some examples, the sidewall of the tenon 203 includes a first abutting portion 204 and a second abutting portion 205, where the first abutting portion 204 is used to abut against the connection unit 301, and the second abutting portion 205 abuts against the standing water component, so as to avoid forming a large gap between the connection unit 301, the first standing water structure 101, the second standing water structure 102 and the tenon 203, and affect the stability of the three-party tenon connection structure.

Specifically, since the first standing water structure 101 and the second standing water structure 102 are angled, the second abutting portions 205 are provided at an angle, an edge is formed between the two second abutting portions 205, and the two second abutting portions 205 can abut against the side surfaces of the first standing water structure 101 and the second standing water structure 102, respectively.

Further, in order to avoid the horizontal displacement of the connection unit 301 on the tenon 203, the first abutting portion 204 is provided with a plurality of raised rib structures, and the inner wall of the groove structure 302 is correspondingly disposed. The rib structure can provide a reverse resistance when there is a tendency for the connection unit 301 to be horizontally displaced, thereby ensuring that the connection structure is positionally stable.

In order to avoid the displacement of the connection unit 301 in the vertical direction on the tenon 203, a protruding support structure is disposed at the bottom of the first abutment 204, and the support structure is supported at the bottom of the connection unit 301. Specifically, the raised ridge structure on the first abutment 204 results from cutting, with a raised support structure naturally formed at the end of the cutting stroke.

As shown in fig. 10, 11 and 12, in the second embodiment, the connection unit 301 is a profile structure on the tenon 203, and the connection unit 301 is not separately provided. The connection unit 301 is disposed on a side wall of the tenon 203, so that the connection unit 301 is in contact with the first water standing structure 101 and the second water standing structure 102, and the connection unit 301 is disposed on a surface of the tenon 203, which is close to the first water standing structure 101 and the second water standing structure 102.

Further, the connection unit 301 is configured as a mating groove, and the portion of the tenon 203 configured as the mating groove can still maintain a larger outer diameter due to a larger volume of the tenon 203, so as to improve the structural strength of the tenon 203 and avoid the tenon 203 from being damaged or broken under the stress condition.

As shown in fig. 13, specifically, protruding units 206 are disposed on the sidewalls of the first water standing structure 101 and the second water standing structure 102, and a gap is formed between the mating groove and the mating surface 202 on both sides, so that the first water standing structure 101 and the second water standing structure 102 can be inserted. When the first standing water structure 101 and the second standing water structure 102 are inserted into the gaps, the protruding units 206 are also inserted into the matching grooves at the same time, so that profile matching is formed, the protruding units 206 can keep stable longitudinal positions under the limiting action of the inner walls of the matching grooves, namely, the longitudinal positions of the first standing water structure 101 and the second standing water structure 102 are ensured to be stable, and the first standing water structure 101 and the second standing water structure 102 are prevented from falling off from the supporting legs 201.
