Specific embodiment
Illustrate the embodiment of the utility model by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the utility model easily.
It please refers to Fig.1 to Fig.4.It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., only to
Coordinate the revealed content of specification, so that those skilled in the art understands and reads, be not limited to the utility model
Enforceable qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or size
Adjustment, in the case where not influencing the effect of the utility model can be generated and the purpose that can reach, should all still fall in the utility model
Revealed technology contents are obtained in the range of covering.Meanwhile in this specification it is cited as " on ", " under ", " left side ",
The term on " right side ", " centre " and " one " etc. is merely convenient to the clear rather than enforceable to limit the utility model of narration
Scope, relativeness are altered or modified, enforceable when being also considered as the utility model in the case where changing technology contents without essence
Scope.
As shown in figures 1-4, the utility model provides a kind of timing belt pulley pre-tightening apparatus, the belt pulley pre-tightening apparatus
Including but not limited to：Two fastening nail 1, two bracket, 3, four butterfly nuts 2 and fixed plate 4.The fastening follows closely 1
U-shaped, the bottom 101 of two arm lower parts of arm 102 and connection including both sides, the arm 102 of each fastening nail 1 are set
Put matching nut 2；External screw thread is set on arm, in the present embodiment, the fixing piece be butterfly nut 2, set with
The matched internal thread of external screw thread, butterfly nut use enhanced convenience.
Each bracket 3 is strip structure, in this embodiment, in the cuboid of rule, each bracket
On also set up two grooves 301, the groove 301 is the quadrangle of rule, and main purpose is to place timing belt pulley
Transverse axis 6.Certainly it may also be at other, such as two mounting holes be set, as long as the transverse axis 6 of belt pulley can be fixedly mounted.
In the present embodiment, screw hole 302 is also set up on bracket 3, its main purpose prevents to further fastener be utilized to fix transverse axis
Transverse axis moves.
The fixed plate 4 is platy structure in the present embodiment, in the present embodiment, described solid for the rectangle of rule
Mounting hole 401 is set on fixed board 4.Its main purpose is in order to which fixed plate 4 is mounted in other stationary supports.
In use, the arm 102 of the fastening nail 1 is all also cross fixed plate 4 and a bracket 3, it is each described
Fastening nail 1 two arm positions positioned at groove between, in the present embodiment, it is described fastening nail be symmetrically distributed in it is described tightly
