[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work, any modifications, equivalent replacements, improvements, etc., should be included in the protection scope of the utility model.

[0023] like Figures 1 to 4 As shown, this embodiment discloses a novel adjustable pipe connection structure, including a base 1, a support member 2 is detachably connected to the upper end of the base 1, a mounting member 3 is detachably connected to the top end of the support member 2 and is connected to a stainless steel support member through the mounting member 3;

[0024] The base 1, the support member 2 and the mounting member 3 are all plastic members.

[0025] The base 1 is arranged in a cylindrical shape and is a variable diameter structure with a large outer diameter at the bottom and a small outer diameter at the top. A center groove 101 is arranged at the center position of the upper end of the base 1. The support member 2 and the mounting member 3 are both longitudinally arranged circular tubes. The bottom end of the support member 2 is inserted into the center groove 101. A first internal thread structure is arranged on the inner side of the top end of the support member 2 and is threadedly connected to a first external thread structure arranged at the bottom end of the mounting member 3 through the first internal thread structure. A second internal thread structure is arranged on the inner side of the top end of the mounting member 3 and is threadedly connected to a second external thread structure arranged at the bottom end of the stainless steel support member through the second internal thread structure.

[0026] The bottom end of the central groove 101 is provided with a vent hole 103 for penetrating the bottom end wall of the base 1, so as to achieve the exhaust effect when the bottom end of the support member is inserted into the central groove, and avoid the situation that the support member is difficult to insert into the central groove due to the air pressure problem in the central groove when the support member is blocked;

[0027] A connecting convex ring 201 is integrally formed on the outer circumference of the bottom end of the support member 2, and there are two connecting convex rings 201 which are arranged longitudinally; an inner circumference of the bottom end of the center groove 101 is provided with an inward-shrinking diameter-changing structure 102, and the inner diameter of the inward-shrinking diameter-changing structure 102 is smaller than the inner diameter of the center groove 101, and the inner diameter of the inward-shrinking diameter-changing structure 102 is adapted to the outer diameter of the bottom end of the support member 2; when the bottom end of the support member 2 is inserted into the center groove 101, the outer edge of the connecting convex ring 201 contacts the inner wall of the center groove 101, and the bottom end of the connecting convex ring 201 contacts the top of the inward-shrinking diameter-changing structure 102.

[0028] This design allows a larger contact area between the support and the inner wall of the center groove, and its connection structure is more stable, ensuring a stable connection between the support and the base.

[0029] The support member 2 has three hand-holding protrusions 202 integrally formed on the outer circumference of the top end. The three hand-holding protrusions 202 are arranged at equal intervals along the circumferential direction of the support member 2 , and the length direction of the hand-holding protrusions 202 is consistent with the axial direction of the support member 2 .

[0030] Two anti-slip protrusions 203 are arranged between adjacent hand-held protrusions 202. The two anti-slip protrusions 203 are arranged along the circumferential direction of the support member 2. The cross-sectional outer diameter of the anti-slip protrusion 203 is smaller than the cross-sectional outer diameter of the hand-held protrusion 202. The length direction of the anti-slip protrusion 203 is consistent with the axial direction of the support member 2.

[0031] The hand-holding protrusions and the anti-slip protrusions can both increase the friction between the human hand and the support member, making it easier for people to rotate the support member, thereby improving the convenience of its installation and height adjustment.

[0032] A limiting convex ring 301 is integrally formed on the outer periphery of the middle part of the mounting member 3, and the outer diameter of the limiting convex ring 301 is larger than the inner diameter of the top end of the supporting member 2; the limiting convex ring can limit the height position of the top end of the supporting member after connection, and at the same time improve the stability of the connection structure between the supporting member and the mounting member after the connection is tight.

[0033] The utility model adopts a design that the top of the base is connected with the support member, the mounting member and the pillar member, so that when installing the shelf, the base is directly placed on the ground, and then the bottom end of the support member is inserted into the central groove of the base, and then the top end of the support member is threadedly connected with the bottom end of the mounting member, and finally the top end of the mounting member is connected with the bottom end of the pillar member; the single pillar member of the shelf is supported by the base, so that the bottom end of the pillar member of the shelf can be stably placed on the ground; at the same time, when the placement area of ​​the shelf is uneven, the rotation structure between the support member and the mounting member can be changed by rotating the support member, so as to achieve the height adjustment of the mounting member and the single pillar member, so that the shelf can be stably placed on the ground in various areas, thereby improving the use effect of the shelf; and the utility model can adjust the support members at the bottom ends of multiple pillar members of the shelf at the same time, so that the overall height of the shelf is changed, thereby achieving the height adjustment effect of the shelf; the entire connection structure in the utility model has low cost and quick assembly, which further improves the use effect of the utility model.
