In addition, the words "first", "second" and the like are only used to distinguish multiple components or structures with the same or similar structures, and do not represent any special limitation on the setting order or connection relationship.

[0045] Please refer to Figures 1 to 6 In one aspect, the present invention provides a three-axis connection structure 100, including: a connection body 1, an X-axis connection part 2, a Y-axis connection part 3 and an expansion connection part. For ease of understanding, please refer to Figure 1, the extension direction of the X-axis connection part 2 is defined as the X direction, the extension direction of the Y-axis connection part 3 is defined as the Y direction, and the extension direction of the expansion connection part is defined as the Z direction. The connection body 1 is a cubic structure as a whole, and the three edges on the outside are rounded to reduce the edges from scratching the user. The X-axis connection part 2 is arranged in the X direction of the connection body 1, and is used for assembly and connection with the crossbar 200; the Y-axis connection part 3 is arranged in the Y direction of the connection body 1, and is used for assembly and connection with the longitudinal bar 300; the expansion connection part is arranged in the Z direction of the connection body 1, and is used to cooperate with the radial force element (not shown in the figure) to frictionally lock the connection with the inner tube wall of the vertical rod 400 with a tubular end. Specifically, the expansion connection part is an element that can expand radially after being subjected to force, thereby forming a strong friction force or bite force between the inner tube wall of the vertical rod 400 with a tubular end. In this embodiment, the connection body 1, the X-axis connection part 2, the Y-axis connection part 3 and the expansion connection part are plastic injection molded integrally, and then made of a connector made by cutting. Of course, in other embodiments, the connecting body 1, the X-axis connecting part 2, the Y-axis connecting part 3 and the expansion connecting part may also be split structures made of the same or different materials and assembled together by fasteners, snaps or other means, without specific limitation herein.

[0046] The Z direction of the connection body 1 of the triaxial connection structure 100 is provided with an expansion connection part for cooperating with a radial force element to frictionally lock and connect with the inner wall of the vertical rod 400 with a tubular end. Since the expansion connection part is tightly attached to the inner wall of the vertical rod 400 when expanding, a huge friction force and mechanical bite force are generated to fix the expansion connection part in the vertical rod 400, so that the technical solution has the advantage of high connection strength.

[0047] In order to make the connection between the expansion joint and the vertical rod 400 with a tubular end detachable, optionally, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 6In this embodiment, the connecting body 1 is provided with a through hole along the Z direction; specifically, the through hole is a stepped hole a. The expansion connection portion is an expansion sleeve 4; the radial force-applying element includes: a screw 8 and a nut 9. Among them, the expansion sleeve 4 with a tapered inner hole is coaxially arranged with the stepped hole a and is located on the small-diameter side of the stepped hole a. The screw 8 is passed through the through hole, that is, the rod of the screw 8 passes through the stepped hole a of the connecting body 1, and the head of the screw 8 is restricted to the large-diameter end of the stepped hole a; the nut 9 is threadedly connected to the screw 8, and the rotation direction is relatively fixed by the inner circumference of the expansion sleeve 4, and is used to expand or contract the expansion sleeve 4 when moving along the Z axis. That is, the nut 9 is preset on the inner circumference of the expansion sleeve 4, and the nut 9 cannot rotate relative to the expansion sleeve 4. In this way, when the bolt and the nut 9 cooperate, the nut 9 can be moved along the Z-axis direction by rotating the bolt. Since the inner hole of the expansion sleeve 4 has a taper, in this way, when the screw rod 8 is rotated in one direction, the nut 9 moves along the Z-axis toward the end with a smaller inner diameter of the expansion sleeve 4, and the expansion sleeve 4 can be gradually stretched open, so that the expansion sleeve 4 and the inner tube wall of the vertical rod 400 fit closely; and when the bolt is rotated in the opposite direction, the nut 9 moves along the Z-axis toward the end with a larger inner diameter of the expansion sleeve 4, the expansion sleeve 4 can be gradually contracted, so that the friction between the expansion sleeve 4 and the inner tube wall of the vertical rod 400 is reduced. In this way, the connection between the expansion connection part and the vertical rod 400 with a tubular end is realized as a detachable connection. In this embodiment, the outer diameter of the threaded rod part of the screw rod 8 should be smaller than the inner hole diameter of the expansion sleeve 4, so that the interference between the screw rod 8 and the inner wall of the expansion sleeve 4 can be avoided, and the inner wall of the expansion sleeve 4 can be avoided when rotating.

[0048] Optionally, see Figure 2 , Figure 3 and Figure 6In this embodiment, the wall of the expansion sleeve 4 has axial cutouts c arranged at intervals, that is, the expansion sleeve 4 is composed of a plurality of expansion strips 41 coaxially and arranged at intervals. The inner diameter of the expansion sleeve 4 gradually increases from the connection end to the free end, that is, the inner hole of the expansion sleeve 4 is an inverted cone; in order to match the shape of the inner hole of the expansion sleeve 4, the nut 9 has an outer peripheral wall with a taper matching the inner diameter of the expansion sleeve 4, so that it can move better along the Z axis; in this way, the nut 9 can open the expansion sleeve 4 when it moves downward along the Z axis, and contract the expansion sleeve 4 when it moves upward. It can be understood that in other embodiments, the inner diameter of the expansion sleeve 4 can also be set to gradually decrease from the connection end to the free end, that is, the inner hole of the expansion sleeve 4 is a cone, and the nut 9 has an outer peripheral wall with a taper matching the inner diameter of the expansion sleeve 4, so that the nut 9 can open the expansion sleeve 4 when it moves upward along the Z axis, and contract the expansion sleeve 4 when it moves downward, and no specific restrictions are made here. It can be understood that in other embodiments, the nut 9 can also be set at the large-diameter end of the step hole a in the radial force-applying element, and the step hole a of the screw rod 8 will be provided, and the screw rod 8 has a light rod portion with a taper matching the inner diameter of the expansion sleeve 4; the nut 9 is rotated to make the screw rod 8 move up and down, and the light rod portion of the screw rod 8 is used to expand or contract the expansion sleeve 4, so that the connection between the expansion connection portion and the vertical rod 400 with a tubular end is a detachable connection.

[0049] Optionally, see Figure 3 In this embodiment, the expansion sleeve 4 is in a square tube shape. Of course, in other embodiments, the expansion sleeve 4 may also be in a round tube shape or other polygonal tube shape to adapt to the vertical rod 400 with different tubular ends.

[0050] In order to prevent the assembled screw rod 8 from getting damp, rusty, or dusty, etc., optionally, please refer to Figure 4 and Figure 6 In this embodiment, the three-axis connection structure 100 also includes a plug cover (not shown in the figure), and a plug hole b is coaxially provided on the side of the step hole a away from the expansion sleeve 4, and the plug cover is inserted into the plug hole b to cover the screw 8.

[0051] Optionally, the X-axis connection part 2 can be detachably assembled or fixedly assembled with the crossbar 200; the Y-axis connection part 3 can be detachably assembled or fixedly assembled with the longitudinal bar 300, and no specific limitation is made here. Figure 1 and Figure 3In this embodiment, the X-axis connection part 2 and / or the Y-axis connection part 3 are plug-in protrusions formed by the connection body 1 protruding outward, and the free end of the plug-in protrusion has a guiding chamfer 5. In this way, the X-axis connection part 2 can be quickly plugged and assembled with the cross bar 200 having a tubular end, and the Y-axis connection part 3 can be quickly plugged and assembled with the longitudinal rod 300 having a tubular end. Of course, the X-axis connection part 2 and / or the Y-axis connection part 3 can also be a threaded structure to achieve a threaded connection with the cross bar 200 or the longitudinal rod 300 having a matching threaded structure. Similarly, the X-axis connection part 2 and / or the Y-axis connection part 3 can also be a concave structure to be assembled and connected with the rod-like structure with a protruding part.

[0052] Optionally, see Figure 3 and Figure 6 In this embodiment, the X-axis connection part 2 and the Y-axis connection part 3 have three slots 6 arranged at intervals along the axial direction. Of course, in other embodiments, the number of slots 6 can also be 1, 2, 4 or more, and the specific number can be set according to the specific size. And the slot 6 can also be set only in the X-axis connection part 2 or only in the Y-axis connection part 3. In order to increase the strength of the side relative to the bottom wall of the slot 6, further, a reinforcing rib 7 is provided along the axial direction on the side of the X-axis connection part 2 and / or the Y-axis connection part 3 away from the notch of the slot 6.

[0053] On the other hand, the embodiment of the utility model further provides a pet box frame (not shown in the figure), including multiple cross bars 200, multiple longitudinal bars 300, multiple vertical bars 400, the three-axis connection structure 100 as described above, and a radial force element that cooperates with the three-axis connection structure 100, the two ends of the same cross bar 200 are respectively connected to the X-axis connection part 2 of the adjacent three-axis connection structure 100, the two ends of the same longitudinal bar 300 are respectively connected to the Y-axis connection part 3 of the adjacent three-axis connection structure 100, and the two ends of the same vertical bar 400 are respectively assembled and connected to the expansion connection part of the adjacent three-axis connection structure 100 with the cooperation of the radial force element.

[0054] Since the pet box frame has all the structures and connection relationships of the three-axis connection structure 100, it has all the advantages of the three-axis connection structure 100, which will not be described in detail here.

[0055] In another aspect, the utility model further provides a pet box (not shown in the figure), comprising the pet box frame as described above, and a wall plate (not shown in the figure) arranged on the pet box frame.
