Description
Technical field
A kind of overload safety device is the utility model is related to, more particularly to a kind of reused antioverloading protection dress
Put.
Background technology
In actual life, often because various failures cause machine phenomena such as overburden, stuck occur, now if
There is no overload protection arrangement, it will cause machine breakdown or major accident, so an overload protective device is essential.
Mechanical overload protective device is generally friction clutch in prior art, when load can bear maximum more than device, by defeated
Enter axle to separate with output shaft to reach antioverloading, but reset is more complicated, and can not be used for multiple times, protection device meeting after overloading
Damage.
The content of the invention
The purpose of this utility model is that solve the deficiencies in the prior art, there is provided the repeatable utilization of one kind, maintenance side
Just, overload protection arrangement simple in construction.
According to the technical solution of the utility model, the reused overload safety device, including output shaft, set
Cylinder and input shaft, the output shaft lower end insertion sleeve upper end, and be connected with each other using the first pin；The sleeve is provided with and the
The groove that one pin mounting hole is integrated, the groove is below the first pin mounting hole；The plate of annular shape is additionally provided with the output shaft
Support, plate support have elastic component with set on output shaft intermarginal on sleeve；The sleeve lower surface is inclined-plane, the input shaft upper end
Provided with the second pin, input shaft upper end insertion sleeve lower end, the second pin is attached on the inclined-plane of sleeve lower surface.
Further, the flexible member is helical spring.
Further, the inclined-plane of the sleeve lower end is wavy.
Further, first pin is mutually perpendicular to the second pin.
Compared with prior art, the utility model has advantages below：
（1）It can be used repeatedly, due to overload protection device will not be caused to damage；
（2）Easy to maintenance, simple-to-maintain can normal use after overloading；
（3）It is simple in construction, it is easy for installation, it is versatile；
（4）Force value can be adjusted as needed.

Embodiment
With reference to specific embodiments and the drawings, the utility model is described in further detail.
As shown in Figure 1 and Figure 2：Reused overload safety device, including output shaft 1, sleeve 4 and input shaft 5,
The upper end of 1 lower end insertion sleeve of output shaft 4, and be connected with each other using the first pin 3.The plate support of annular shape is additionally provided with output shaft 1
1.1, set has elastic component 2 on intermarginal output shaft 1 on plate support 1.1 and sleeve 4, and in one embodiment, flexible member 2 is spiral shell
Revolve spring, simple in construction, convenient material drawing.The lower surface of sleeve 4 is inclined-plane, and the upper end of input shaft 5 is provided with the second pin 6, input shaft 5
The lower end of upper end insertion sleeve 4, the second pin 6 are embedded in the lower edge recess of sleeve 4.Sleeve 4 is provided with and is integrated with the mounting hole of the first pin 3
Groove 4.1, the groove 4.1 is located at below the mounting hole of the first pin 3, and a L-shaped or T are formed on sleeve 4 with the mounting hole of the first pin 3
The opening of shape, shown in the drawings is L-shaped.During normal condition, the first pin 3 is located at the upper end of mounting hole 4.1；When load is beyond setting
After scope, sleeve 4 is moved up in the presence of input shaft 5, and when moving on to maximum position on sleeve 4, the first pin 3 is fallen into groove 4.1, is made
Input shaft 5 is obtained to separate with sleeve 4.Specifically, the inclined-plane of the lower end of sleeve 4 is wavy, the first pin 3 is mutually perpendicular to the second pin 6.
Operation principle：After output shaft 1, flexible member 2, the first pin 3, sleeve 4 are assembled, against the second pin 6 of input shaft 5
Fixed installation.The force value of flexible member 2 is set by calculating, when being supported in rated range, input shaft 5 rotates, and passes through
The output shaft 1 that second pin 6 is connected with moving sleeve 4 and with sleeve 4 rotates, and can now be operating normally.When load is beyond setting
After scope, when the now rotation of input shaft 5 drives the rotation of the second pin 6, the axial thrust load acted on sleeve 4 increases, more than elasticity
Element 2 is supplied to the pressure of sleeve 4, causes sleeve 4 to move upwards, the first pin 3 is fallen into the groove 4.1 of sleeve 4 so that
Input shaft 5 separates with sleeve 4, and now output shaft 1 reaches the purpose of protection no longer as input shaft 5 rotates and rotates.Safeguard
When, the first pin 3 need to be only removed in the groove 4.1 of sleeve 4, device can normal use again.
The utility model can be used repeatedly, and due to overload protection device will not be caused to damage；It is easy to maintenance, occurred
Simple-to-maintain can normal use after load；It is simple in construction, it is easy for installation, it is versatile；Force value can be adjusted as needed.
