In figure: 1 belt pulley, 2 link blocks, 3 protective plates, 4 limited blocks, 5 mounting grooves, 6 through-holes, 7 slide bars, 8 protective blocks, 9 are answered
Position spring, 10 ball racks, 11 balls, 12 high-strength bolts.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Embodiment one
Referring to Fig.1-2, the belt sheave structure of anti-belt abjection, including belt pulley 1 and protective plate 3, protective plate 3 use rectangle
Structure, the both ends of protective plate 3 are integrally formed link block 2, and the effect of link block 2 is to be convenient for the installation of protective plate 3, and
Cooperate the anti-drop function for realizing belt with protective plate 3, link block 2 and protective plate 3 collectively form U-shaped structure, link block 2 and anti-
Backplate 3 is radially fixed to be socketed in belt pulley 1, and protective plate 3 is equipped at least one position-limit mechanism close to the side of belt pulley.
More specifically, position-limit mechanism includes limited block 4, limited block 4 is fixedly connected on the bottom end of protective plate 3, and limited block 4 can
Belt is further limited, prevents from being distorted in its interior protective plate 3, is overturn.
It is highly preferred that link block 2 is fixedly connected on belt pulley 1 by high-strength bolt 12, it can also consolidating by welding
Determine mode to carry out.
It further illustrates, it is above-mentioned to be fixedly connected unless specifically defined or limited otherwise, otherwise to shall be understood in a broad sense, example
Such as, it can be welding, be also possible to gluing, or be integrally formed the customary means well known to those skilled in the art such as setting.
When the utility model is used first by belt sleeve on belt pulley 1, protective plate 3 is then passed through to the connecting plate 2 of two sides
It is inserted radially into the side of belt pulley, is then fixed on belt pulley 1 by high-strength bolt 12, it is anti-that first can be completed at this time
Shield prevents belt and belt pulley 1 to be detached from.
Then due to the setting of limited block 4, belt can be limited in the groove of mlultiple-groove sheave, be plane for side
Belt pulley then only need a limited block 4, to prevent the deformation such as belt is distorted in protective plate 3.
Embodiment two
Referring to Fig. 3-4, the belt sheave structure of anti-belt abjection, including belt pulley 1 and protective plate 3, protective plate 3 use rectangle
Structure, the both ends of protective plate 3 are integrally formed link block 2, and the effect of link block 2 is to be convenient for the installation of protective plate 3, and
Cooperate the anti-drop function for realizing belt with protective plate 3, link block 2 and protective plate 3 collectively form U-shaped structure, link block 2 and anti-
Backplate 3 is radially fixed to be socketed in belt pulley 1, and protective plate 3 is equipped at least one position-limit mechanism close to the side of belt pulley.
Embodiment two is replaced on the basis of retaining embodiment one, by position-limit mechanism from limited block 4 are as follows: slide bar 7 resets bullet
Spring 9, ball rack 10 and ball 11, protective plate 3 offer at least one mounting groove 5 close to the side of belt pulley, mounting groove 5 it is interior
Wall offers the through-hole 6 being in communication with the outside, and 6 internal clearance of through-hole is combined with slide bar 7, and slide bar 7 extends in mounting groove 5 and fixed company
It is connected to ball rack 10, ball 11 is installed in ball rack 10, the part that slide bar 7 is located in mounting groove 5 is arranged with reset spring 9,
This position-limit mechanism, so that ball 11 is fitted in the surface of belt always, can compare embodiment one by the elastic force of reset spring 9
The limit of fixed limited block 4, the performance of anticreep are more preferable, but can increase the rolling friction with belt slightly.
Further, slide bar 7 is far from being fixedly connected with protective block 8, the outer diameter of protective block 8 at one end port of ball rack 10
Greater than the diameter of through-hole 6, the setting of protective block 8 can prevent slide bar 7 from sliding out of through-hole 6.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
