Abstract
The utility model discloses anti-jamming saw blades, including outer ring, inner ring and clamping sheet, sawtooth are provided on the outer ring, the inner ring and the clamping sheet clamp the outer ring, and the clamping sheet is threadedly attached on the inner ring.Outer ring is clamped using inner ring and clamping sheet, under normal circumstances, inner ring and outer ring can move together, when sawtooth is stuck, frictional force deficiency between inner ring and clamp clip and outer ring is less than extraneous resistance, at this moment, inner ring is just detached from outer ring and voluntarily rotates, avoid the occurrence of because sawtooth is stuck and the situation of burn-down of electrical machinery.Can the frictional force size between inner ring and clamp clip and outer ring be adjusted by the dynamics screwed of adjusting nut.
Description
Technical field
The present invention relates to saw blade technical field, more particularly to a kind of anti-jamming saw blade.
Background technology
Present power saws, may be stuck when saw blade encounters huge resistance again, and at this time, motor can not rotate, meeting
Very big heat is generated, equipment damage is caused when serious, it is therefore necessary to be improved.
Invention content
For the deficiencies in the prior art, the present invention provides anti-jamming saw blade, saw blade sawtooth part it is stuck with
Afterwards, saw blade is still able to rotate.
The present invention is achieved through the following technical solutions：Anti-jamming saw blade, it is described including outer ring, inner ring and clamping sheet
Sawtooth is provided on outer ring, the inner ring and the clamping sheet clamp the outer ring, and the clamping sheet is threadedly attached in institute
It states on inner ring.Outer ring is clamped using inner ring and clamping sheet, under normal circumstances, inner ring and outer ring can move together, work as sawtooth card
When dead, the frictional force deficiency between inner ring and clamp clip and outer ring is less than extraneous resistance, and at this moment, inner ring is just detached from outer ring voluntarily
Rotation, avoid the occurrence of because sawtooth is stuck and the situation of burn-down of electrical machinery.It can be adjusted by the dynamics screwed of adjusting nut
Frictional force size between inner ring and clamp clip and outer ring.
In above-mentioned technical proposal, it is preferred that centre position is provided with the through-hole being connected with electric saw on the inner ring.
In above-mentioned technical proposal, it is preferred that the inner ring include center boss and border pressing plate, the outer ring it is interior
The both ends of the surface of side are respectively arranged with the first heavy platform and the second heavy platform, the thickness of the clamping sheet and the depth phase of first heavy platform
Together, the thickness of the pressing plate is identical with the depth of second heavy platform.
The present invention has the advantages that：Outer ring, under normal circumstances, inner ring and outer ring are clamped using inner ring and clamping sheet
It can move together, when sawtooth is stuck, the frictional force deficiency between inner ring and clamp clip and outer ring is less than extraneous resistance, this
When, inner ring is just detached from outer ring and voluntarily rotates, avoid the occurrence of because sawtooth is stuck and the situation of burn-down of electrical machinery.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Fig. 2 for Fig. 1 along the sectional view of A-A.
Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
Referring to Fig. 1 to 2, including outer ring 1, inner ring 2 and clamping sheet 3, sawtooth is provided on the outer ring 1 for anti-jamming saw blade
11, the inner ring 2 and the clamping sheet 3 clamp the outer ring 1, and the clamping sheet 3 is threadedly attached on the inner ring 2.
Outer ring is clamped using inner ring and clamping sheet, under normal circumstances, inner ring and outer ring can move together, when sawtooth is stuck, inner ring
Frictional force deficiency between clamp clip and outer ring is less than extraneous resistance, and at this moment, inner ring is just detached from outer ring and voluntarily rotates, and avoids
Occur because sawtooth is stuck and the situation of burn-down of electrical machinery.Can inner ring and clamping be adjusted by the dynamics screwed of adjusting nut
Frictional force size between piece and outer ring.
Centre position is provided with the through-hole 21 being connected with electric saw on the inner ring 2.
The inner ring 2 includes the boss 22 in center and the pressing plate 23 of border, and the both ends of the surface of the inside of the outer ring 1 are set respectively
The first heavy platform 12 and the second heavy platform 13 are equipped with, the thickness of the clamping sheet 3 is identical with the depth of first heavy platform 12, the pressure
The thickness of plate 23 is identical with the depth of second heavy platform 13.
