Taper pin on interconnecting piece inner wall, the taper pin are provided with locking piece far from connecting rod one end；The luggage interconnecting piece is set on bottom surface
Taper pin can be limited by, which being equipped with, makees the locking groove rotated only with respect to connecting rod.Tightening part and matched taper pin are connected with luggage
The setting in portion makes it possible to be pushed against tightening part on the inner wall of luggage interconnecting piece in the case where by adjusting taper pin, thus real
Effective connection of existing connector and luggage, while direction adjusting taper pin can also realize the easy to disassemble of connecting rod.
Further, be provided with horn-like chamber in the luggage interconnecting piece, the side wall of the horn-like chamber can with rise
Tightening part after opening abuts.In luggage interconnecting piece with tightening part cooperation one end by its structure setting be it is horn-like, to make
Tightening part can more fully spreading, have reached so that the diameter of tightening part a part is greater than the diameter of connecting rod, and is filled
Tightening part after dividing spreading can be realized with the side wall of horn-like structure to abut, to reach a friction and the dual limitation of shape
Effect, further increase bonding strength of the connecting rod in luggage interconnecting piece.
Further, the portion of twisting is provided in the connecting rod.Connecting rod can be conveniently twisted in installation and removal.
Further, the portion of twisting is the outer-hexagonal shape being adapted to nut spanner.This kind of structure can be pulled by general
Connecting rod is effectively fixed on luggage interconnecting piece by hand-held tool.
Further, the tightening part is divided into four parts by the way that slot segmentation is centrosymmetric.Tightening part four parts be divided into both
Can effectively guarantee tightening part tensioner effect, and can reduce make tightening part tensioner deformation needed for power.To facilitate
The fixed installation of connecting rod.
The useful effect of the utility model is: by the way that tightening part and matched taper pin and case are arranged in connecting rod
Packet interconnecting piece enables the effective connection and quick disassembly of completing connecting rod and connecting rod upper roller, and this kind of structure
It can guarantee the integrity that luggage is still ensured that after installation and removal.
Detailed description of the invention

Fig. 2 is the sectional view of Fig. 1；
Fig. 3 is the structure chart after the utility model removal luggage interconnecting piece；
Fig. 4 is the sectional view of connecting rod.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, to the technical scheme in the embodiment of the utility model into
Row clearly and completely describes, it is clear that and the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
A kind of idler wheel connection component in conjunction with shown in Fig. 1 ~ 4, including the connecting rod 1 as ontology, one end of connecting rod 1 is inserted
Enter the luggage interconnecting piece 2 of luggage, transition fit is generally between luggage interconnecting piece 2 and connecting rod 1, wherein to facilitate connecting rod 1
Insertion be inserted into luggage in connecting rod and in order to keep the secured connection of continuous and effective between connecting rod 1 and luggage interconnecting piece 2
Tightening part 11 is provided on one end of interconnecting piece, wherein tightening part can be inserted into luggage company in non-spreading with connecting rod
It in socket part, and is to enable the effective spreading of tightening part, tightening part is provided at least one tensioner slot 111 along its axial direction；It is preferred that
, in order to which tensioner can be uniformly connected on the inner wall of luggage interconnecting piece, tensioner slot 111 can be uniformly distributed four of spoke shape
Item；Screw hole 12 is additionally provided in connecting rod；Taper pin 3 is set in tightening part, is equipped with spiral shell close to one end of connecting rod in taper pin 3
Bar 31 is provided with screw thread compatible with screw hole 12 in connecting rod 1 on screw rod, and taper pin 3 is screwed onto connecting rod by screw rod, In
Taper pin is provided with locking piece 32 far from one end of connecting rod 1；It is compatible therewith, it is provided on the ground of luggage interconnecting piece 2
Locking groove 21, locking piece can be embedded in locking groove 21, can make taper pin that can only occur relatively and connect by the limitation of locking groove
The rotation of extension bar, so as to adjust taper pin in the case where being rotatablely connected bar to the tensioner degree of tightening part.
Its working principle is that: connecting rod 1 is provided with tightening part 11 and is bolted with one end of taper pin 3 in the non-spreading of tightening part
In the case of be first inserted into luggage interconnecting piece 2, and locking piece 32 on taper pin 3 is embedded into locking groove 21 under the action of thrust,
Start to twist connecting rod 1 at this time, be allowed to relatively rotate with taper pin 3, and keep certain thrust, allows locking piece 32 to hold
Continuous is embedded in locking groove 21, when taper pin 3 is in lasting rotation, due to the effect of screw rod 31 and screw hole 12, and taper pin 3 and tightening part
Relative displacement occurs between 11, taper pin 3 generates a thrust to the inner wall of tightening part at the same time, by the outside spreading of tightening part,
And the tightening part of spreading is slowly pushed against on the inner wall of luggage interconnecting piece 2.It is larger between tightening part 11 and luggage interconnecting piece inner wall
Active force also increase frictional force between the two so that connecting rod can continue and effectively be fixed on luggage connection
In portion.And the other end of connecting rod 1 is to keep integrated idler wheel with it, therefore when connecting rod can be fixed on luggage interconnecting piece
When, idler wheel is naturally also able to maintain effective stationary state.And it only need to be by tightening part when to dismantle and replace the idler wheel of damage
Adjust pine, that is, unscrewing the taper pin being screwed onto connecting rod can be realized, when between tightening part and luggage interconnecting piece inner wall there is no compared with
When big pressure, the frictional force between connecting rod and luggage interconnecting piece reduces therewith, and connecting rod can be immediately from luggage interconnecting piece
It extracts.
It is detailed on the basis of the present embodiment, horn-like chamber 22 is provided in luggage interconnecting piece, the horn-like chamber
22 side wall can be touched by the tightening part after spreading, and can be pushed against by tightening part；Preferably, the side of the horn-like chamber
Angle between wall and center axis thereof is less than or equal to the angle after tightening part spreading between its lateral wall and tightening part central axis, with
Guarantee to abut between tightening part and the side wall of horn-like chamber.
Detailed on the basis of the present embodiment, being also provided in connecting rod 1 can assist connecting rod to twist
Twist portion 13, it is preferred that the shape for twisting portion 13 can be outer-hexagonal shape, and the size of the outer-hexagonal shape can be with standard
The shape of hex nut is consistent, so that twisting for screw rod need to only be can be realized by standard wrench.
