The top of limit for tonnage seat is threaded portion, and the lower section of described threaded portion is connecting portion, and the sidewall of described connecting portion is provided with circular hole,
Described spring is placed in described circular hole, and the inner face of described spring is against the bottom of described circular hole, the outer face of described spring
On be placed with described roller, described limit for tonnage friction plate, limit for tonnage ratchet the most sequentially overlap and are connected on described connecting portion, described
Limit for tonnage pressing plate is arranged on the right side of described limit for tonnage ratchet, and described limit for tonnage disc spring is arranged on the right side of described limit for tonnage pressing plate, described limit
Carry locking nut be threaded on described threaded portion and lock.
Further, the U-lag on protruding and described limit for tonnage seat on described limit for tonnage pressing plate matches, described limit for tonnage pressure
When plate is installed on described limit for tonnage seat, described projection snaps onto in described U-lag.
Further, being evenly equipped with multiple groove in the centre bore of described limit for tonnage ratchet, described groove one end is set to directly
The face other end is set to inclined-plane, and when described limit for tonnage ratchet rotates counterclockwise, described roller is ejected by described spring force effect and snaps into
In described groove, described limit for tonnage ratchet drives described limit for tonnage seat to rotate together.
Further, the quantity of described groove is 8, and is distributed on the edge of the centre bore of described limit for tonnage ratchet.
Compared with prior art, Advantageous Effects of the present utility model:
The anti-slipping device of this utility model, including roller, spring, limit for tonnage seat, limit for tonnage friction plate, limit for tonnage ratchet, limit for tonnage
Pressing plate, limit for tonnage disc spring and limit for tonnage locking nut, the limit for tonnage seat of stepped column structure includes threaded portion and connecting portion, connecting portion
Sidewall on be provided with circular hole, spring and roller and be placed in circular hole, and spring is positioned at inner side roller and is positioned at outside, because of limit for tonnage spine
The special construction that centre bore is multiple groove of wheel, when weight is in the case of not overload, limit for tonnage ratchet rotates clockwise,
Weight steadily rises；When weight declines, limit for tonnage ratchet rotates counterclockwise, because having spring and rolling in the circular hole of limit for tonnage seat
Post, in this time, roller is ejected in the groove being connected to limit for tonnage ratchet by spring, and such limit for tonnage ratchet drives limit for tonnage seat together
Rotate, serve the effect that counnter attack is skidded.This utility model is skillfully constructed, reasonable in design, by spring and the reasonable cloth of roller
Office, effectively eliminates the generation of skidding when limit for tonnage ratchet rotates backward.

Detailed description of the invention
As shown in Figures 1 to 3, a kind of anti-slipping device of Lever Blocks limit for tonnage, including roller 1, spring 2, limit for tonnage seat 3, limit
Carrying friction plate 4, limit for tonnage ratchet 5, limit for tonnage pressing plate 6, limit for tonnage disc spring 7 and limit for tonnage locking nut 8, described limit for tonnage seat 3 is specially rank
Scalariform column structure, the top of limit for tonnage seat 3 is threaded portion, and the lower section of described threaded portion is connecting portion, the side of described connecting portion
Being provided with circular hole on wall, described spring 2 is placed in described circular hole, and the inner face of described spring 2 is against the bottom of described circular hole,
Being placed with described roller 1 on the outer face of described spring 2, described limit for tonnage friction plate 4, limit for tonnage ratchet 5 the most sequentially overlap even
Receiving on described connecting portion, described limit for tonnage pressing plate 6 is arranged on the right side of described limit for tonnage ratchet 5, and described limit for tonnage disc spring 7 is arranged on institute
Stating the right side of limit for tonnage pressing plate 6, described limit for tonnage locking nut 8 is threaded on described threaded portion and locks.
The U-lag on protruding and described limit for tonnage seat 3 on described limit for tonnage pressing plate 6 matches, and described limit for tonnage pressing plate 6 is installed
Time on described limit for tonnage seat 3, described projection snaps onto in described U-lag.
As shown in Figure 2,3, being evenly equipped with multiple groove in the centre bore of described limit for tonnage ratchet 5, described groove one end is set to
Face the other end directly and be set to inclined-plane, described limit for tonnage ratchet 5 when rotating counterclockwise described roller 1 by described spring 2 elastic force effect bullet
Card release is in described groove, and described limit for tonnage ratchet 5 drives described limit for tonnage seat 3 to rotate together.
The quantity of described groove is 8, and is distributed on the edge of the centre bore of described limit for tonnage ratchet 5.
Course of action of the present utility model is as follows:
As shown in Figure 2,3, during utility model works, because the centre bore of limit for tonnage ratchet 5 is special groove structure, weight
Thing in the case of an overload time, limit for tonnage ratchet 5 rotates clockwise, and roller 1 can be expressed in circular hole by inclined-plane, because of beyond limit for tonnage
Setting weight, so limit for tonnage ratchet 5 skids, weight does not increases；But when weight is in the case of not overload, limit for tonnage ratchet 5
Rotating clockwise, weight steadily rises；When weight declines, limit for tonnage ratchet 5 rotates counterclockwise, if limit for tonnage ratchet skids, because of limit
Having spring 2, roller 1 in carrying the circular hole of seat 3 processed, now roller 1 can be ejected by spring 2, and has the roller 1 of half to snap in limit for tonnage spine
In the groove of wheel 5, limit for tonnage ratchet 5 can drive limit for tonnage seat 3 to rotate together, effectively eliminates when limit for tonnage ratchet 5 rotates backward and beats
The generation of sliding phenomenon.
