The flange of abutting.
By using above-mentioned technical proposal, flange is abutted with the two side of belt so that belt be always positioned at two flanges it
Between, the axial dipole field of belt is limited, while when side side high is low because of force unbalance for belt, flange and belt side
Side wall high is abutted, it is therefore prevented that tensioning failure caused by tensioning wheel abjection belt.
It is of the present utility model to be further arranged to：The spiral shell perpendicular to the belt end face is fixedly connected with the containment vessel
Mother, the adjusting rod is provided with screw thread and is connected with the nut thread.
By using above-mentioned technical proposal, the setting of nut increases the contact area of containment vessel and adjusting rod, and increase is adjusted
The stability of pole, it is to avoid the circumference of adjusting rod is rocked, by the threaded connection of adjusting rod and nut, realizes the spiral of adjusting rod
Rise or fall.
It is of the present utility model to be further arranged to：The adjusting rod is held away from being fixedly connected with one end of the fix bar
Hold knob.
By using above-mentioned technical proposal, the setting of button is gripped, increase the contact area of adjusting rod and hand, convenient behaviour
The gripping of author.
It is of the present utility model to be further arranged to：Including being fixedly connected on the internal side of shell and connecting with the axis of rotation
The spindle housing for connecing, the containment vessel is fixedly connected on the spindle housing near one end of the rotating shaft.
By using above-mentioned technical proposal, containment vessel is fixed by 2 points with casing and spindle housing, it is to avoid protection
Shell is contradicted because circumferentially rotating with belt, so as to influence the rotation of belt.
It is of the present utility model to be further arranged to：The two ends of the containment vessel are semicircle.
By using above-mentioned technical proposal, the former material doses for making containment vessel is reduced, thus it is cost-effective, and the Beauty
See.
It is of the present utility model to be further arranged to：The lateral wall of the casing is provided with the support feet for support machine casing,
Support is fixedly connected with below the support feet, the motor is fixedly connected on the support.
By using above-mentioned technical proposal, the setting of support feet so that casing can stablize setting on the ground；Support sets
Put, the contact area on increase support feet and ground reduces the pressure suffered by ground, protects ground not to be damaged；Motor is arranged on
On support, the load-bearing of casing is reduced, it is to avoid cause casing load-bearing to deform because motor is arranged on casing.
In sum, the utility model has the advantages that：By setting containment vessel, the protection to belt is realized；
By setting adjusting rod, fix bar, tensioning wheel and sleeve so that adjusting rod drives fix bar to decline, and tensioning wheel is with fix bar
Decline with belt push against, the setting of sleeve, realize the axial slip of fix bar with it is circumferentially fixed, it is achieved thereby that belt
Tightly；The setting of nut, increases the stability of adjusting rod, it is to avoid the circumference of adjusting rod is rocked.
