On, the lateral wall of the location division and the madial wall of expansion sleeve fit.
The utility model is further set:The expansion sleeve includes about the two expansion sub-sets being oppositely arranged, wherein two
It is individual expansion sub-set be symmetrical structure, wherein expansion sub-set be provided with clearance groove and cone sheets, when one expand sub-set to another
Expand during sub-set pressing, the cone sheets in the expansion sub-set can strut the clearance groove for expanding sub-set corresponding thereto, make
The external diameter that sub-set must be expanded becomes big.
The utility model is further set:The tail end face of the fastening bolt is provided with counterbore.
The utility model beneficial effect:When needing connection hollow pipe, fastening bolt first passes through central spacer and is arranged at
In expansion sleeve so that fastening bolt is placed at the central axis of expansion sleeve, it will not shift, be easy to the later stage to fix, then band
The expansion sleeve for having fastening bolt is previously positioned in the Single port of hollow pipe, and hollow pipe is directed at the through hole of spherical connection, and rotation is tight
Fixing bolt is connected with through hole whorl, in rotary course, and the head of the fastening bolt can press expansion sleeve so that expansion sleeve
External diameter become be fixed on hollow pipe greatly, hollow pipe is fixed on ball link, hollow pipe in addition is also by above-mentioned side
Formula is realized and is connected to each other, and realizes the assembling to combined cabinet, simple in construction, is easily installed, is screwed while adopting, repeatable to tear open
Dress, and screw is hidden in hollow pipe, does not interfere with the overall attractive in appearance of combined cabinet.

Embodiment
1 to Fig. 6 a kind of combined cabinet of the utility model is described in further details referring to the drawings.
A kind of combined cabinet, including cabinet 1 and for the hollow pipe 2 on the seamed edge of cabinet 1, wherein cabinet 1 by
Side plate and laminate are surrounded to form a cube structure, and the connection component 3 for being used for connecting hollow pipe 2 is provided with the apex of cabinet 1;
The connection component 3 includes ball link 31, expansion sleeve 32 and fastening bolt 33, and the ball link 31 is provided with some
Individual interconnected through hole 311, the through hole 311 is provided with internal thread, and the expansion sleeve 32 is placed in hollow pipe 2, the fastening
One end of bolt 33 is threadedly coupled through expansion sleeve 32 with the through hole 311 of ball link 31, when rotational fastener bolt 33, institute
Expansion sleeve 32 can be pressed by stating the head of fastening bolt 33 so that the external diameter of expansion sleeve 32, which becomes, to be fixed on hollow pipe 2 greatly, expansion sleeve
32 concrete structure is, wherein the expansion sleeve 32 includes about the two expansion sub-sets 321 being oppositely arranged, two of which expansion
Sub-set 321 is symmetrical structure, wherein expansion sub-set 321 is provided with clearance groove 3211 and cone sheets 3212, sub-set is expanded when one
During 321 press to another expansion sub-set 321, the cone sheets 3212 in the expansion sub-set 321 can be strutted corresponding thereto
The clearance groove 3211 of sub-set 321 should be expanded so that the external diameter of expansion sub-set 321 becomes big, for the ease of expanding the external diameter of sub-set 321
Become big, expansion sub-set 321 can be connected by two panels.
The connection component 3 also includes central spacer 34, and the central spacer 34 includes abutment sleeve 341 and fixed
The location division 342 at the two ends of position sleeve 341;The central spacer 34 is set in fastening bolt 33 by abutment sleeve 341,
The madial wall of the lateral wall and expansion sleeve 32 of the location division 342 fits so that fastening bolt 33 passes through central spacer 34
When being placed in expansion sleeve 32, will not double swerve, be easy to rotational fastener bolt 33 to be assembled.
