Power input equipment is damaged.
Utility model content
According to deficiency of the prior art above, the technical problems to be solved in the utility model is：A kind of overload is provided to protect
Shield axle, its simple structure, efficiently avoid because clutch end have very big resistance when, occur axle or power input equipment
The phenomenon of damage.
Overload protection shaft described in the utility model, including upper semiaxis and lower semiaxis, it is characterised in that：In upper semiaxis lower end
Fixture block is connected with, several draw-in grooves are offered in upper fixture block, lower fixture block is arranged above in lower semiaxis, on lower fixture block top
Portion is provided with the projection that identical with draw-in groove number and mutual transmission coordinates, and lower fixture block bottom is vertically fixed axle sleeve, and axle sleeve is enclosed within
Connect on lower semiaxis and by being bonded, gap is left between axle sleeve upper end and lower semiaxis upper end, and the width in gap is more than projection
Highly, the elastic component for pushing up lower fixture block is provided between lower fixture block and lower semiaxis.
Further, preferably described elastic component includes baffle ring, and baffle ring is arranged on the lower semiaxis below axle sleeve, and baffle ring is to axle
The distance of set is provided with the first spring more than raised height between baffle ring and lower fixture block.
Further, preferably described elastic component includes second spring, and second spring is provided between lower fixture block and lower semiaxis
In axle sleeve.
Further, preferably described first spring housing is on axle sleeve, and upper end is withstood on lower fixture block, and its lower end withstands on baffle ring
On.In practical application, a roll can also be surrounded, between lower fixture block and baffle ring from multiple springs.
Compared with prior art, the utility model has the advantages that：
By overload protection shaft described in the utility model, its simple structure efficiently avoid because clutch end has
During very big resistance, there is the phenomenon that axle or power input equipment are damaged.If the design is applied on the power transmission shaft of lorry,
Can further prevent the serious overload behavior of lorry from occurring.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment one；
Fig. 2 is the structural representation of embodiment two；
In figure：1st, upper semiaxis 2, upper fixture block 3, draw-in groove 4, raised 5, lower fixture block 6, the first spring 7, axle sleeve 8, gear
Ring 9, lower semiaxis 10, second spring.
Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings：
Below by way of specific embodiment, the utility model is described in further detail, but is not used to limit the utility model, all
Within spirit of the invention and principle, any modification, equivalent substitution and improvements made etc. should be included in of the present utility model
Within protection domain.
Embodiment one
As indicated, the overload protection shaft, including upper semiaxis 1 and lower semiaxis 9, it is connected with fixture block in the lower end of upper semiaxis 1
2, several draw-in grooves 3 are offered in upper fixture block 2, lower fixture block 5 is arranged above in lower semiaxis 9, set at the top of lower fixture block 5
There is the projection 4 that identical with the number of draw-in groove 3 and mutual transmission coordinates, the lower bottom of fixture block 5 is vertically fixed axle sleeve 7, and axle sleeve 7 is enclosed within down
Connect on semiaxis 9 and by being bonded, gap is left between the upper end of axle sleeve 7 and the lower upper end of semiaxis 9, and the width in gap is more than raised 4
Height, the elastic component for pushing up lower fixture block 5 is provided between lower fixture block 5 and lower semiaxis 9.
In the present embodiment, the elastic component includes baffle ring 8, and baffle ring 8 is arranged on the lower semiaxis 9 of the lower section of axle sleeve 7, and baffle ring
Height of the distance of 8 to axle sleeve 7 more than raised 4, is provided with the first spring 6 between baffle ring 8 and lower fixture block 5；First bullet
Spring 6 is enclosed within axle sleeve 7, and upper end is withstood on lower fixture block 5, and its lower end is withstood on baffle ring 8.
When mounted, it is clutch end to use semiaxis 1 to the design, and lower semiaxis 9 is power intake, is normally driven shape
Under state, in the presence of the first spring 6, raised 4 are pushed away in draw-in groove 3, so as to play gearing；When upper semiaxis 1 has very big
During resistance, raised 4 can overcome the elastic force of the first spring 6 to jump out from draw-in groove 3, and lower fixture block 5 is rotated further, and upper semiaxis 1 is relative
Static, so as to play a protective role.In use, the elastic force of the first spring 6 is selected, depending on upper semiaxis 1 when designing most
Big rotating torque.
Embodiment two
It is changed on the basis of embodiment one, converting the elastic component includes second spring 10, and second spring 10 sets
It is equipped with the axle sleeve 7 between lower fixture block 5 and lower semiaxis 9.
Other are with embodiment one.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.This
The technical staff of industry is retouched in above-described embodiment and specification it should be appreciated that the utility model is not restricted to the described embodiments
That states is merely illustrated the principles of the invention, and on the premise of the utility model spirit and scope are not departed from, the utility model can also
There are various changes and modifications, these changes and improvements are both fallen within the range of claimed the utility model.The utility model will
Protection domain is sought by appending claims and its equivalent thereof.
