Abstract

The utility model provides a bolt device, which comprises a bolt seat and a support frame arranged on the bolt seat, wherein a slip rod is mounted in a through-hole of the support frame and can move along the axis of the through-hole. One end of a connecting rod is hinged with the slip rod through a first pin shaft, and the other end of the connecting rod is hinged with the middle part of a swing rod through a second pin shaft. One end of the swing rod is hinged with the support frame through a third pin shaft, and the other end of the swing rod passes through the through-hole arranged at one end of a bolt. A thin rod side of the bolt passes through a center hole of an end cover and is nested into a guide pipe. One side of the guide pipe is fixedly connected with the end cover, the other side of the guide pipe is fixedly connected with a side surface of a supporting foot, and the side surface of the supporting foot is fixedly connected with the support frame. One side surface of the supporting foot is supported on a limit surface of the bolt seat. The bolt can pass through the through-hole arranged on the support foot and be inserted in an inserting hole of the bolt seat under the guide of the guide pipe. A spring is mounted in the guide pipe, one side of the spring is propped against the end cover, and the other side of the spring is propped against a step surface of the bolt.

Description

A kind of bolt device

Technical field

The utility model relates to a kind of bolt device.

Background technology

At present, general bolt device adopts hydraulic lock, and power supply and hydraulic power source need be provided, complex structure, and it is big to take up room, component requirement on machining accuracy height, assembly difficulty is big, the cost height, leakage of oil easily, reliability is low.

Summary of the invention

The utility model provides a kind of pure mechanical pin device, does not need to provide power supply and hydraulic power source, and simple in structure, compact, it is little to take up room, and the component requirement on machining accuracy is low, and assembling is simple, convenient, and cost is low, the reliability height.

For achieving the above object, the utility model is taked following technical scheme:

The utility model comprises plug housing and is arranged on bracing frame on the plug housing; The slippage bar is installed in the through hole of bracing frame, can move along through-bore axis, and connecting rod one end is hinged by first bearing pin and slippage bar, and the connecting rod other end is hinged by second bearing pin and fork middle part; Fork one end is hinged by the 3rd bearing pin and bracing frame, and the other end passes in the through hole of latch one end; The thin bar side of latch is passed end cap central bore and is nested in the conduit, conduit one side and end cap connect firmly, opposite side and leg side connect firmly, leg side and bracing frame connect firmly, leg has a lateral support on the plug housing confined planes, and the through hole that latch can pass under the guiding of conduit on the leg inserts in the jack of plug housing, and spring is installed in the conduit, one side withstands on the end cap, and opposite side withstands on the cascaded surface of latch.

At opposite side symmetric arrangement connecting rod, fork, latch, end cap, spring, the conduit of slippage bar, and the hinging pin shaft of the hinging pin shaft of fork and bracing frame, fork and connecting rod.

Adopt the utility model of technique scheme, utilize connecting rod slider mechanism to realize the plug function of latch, need not to provide power supply and hydraulic power source, simple in structure, compact, it is little to take up room, and the component requirement on machining accuracy is low, and assembling is simple, and cost is low, the reliability height; Utilize lever force amplification principle and connecting rod slider mechanism dead-centre position, make the latch Plug Action more laborsaving, reliable.

1. bracing frames among the figure, 2. connecting rod, 3. slippage bar, 4. fork, 5. latch, 6. spring, 7. end cap, 8. conduit, 9. leg, 10. plug housing, 11. first bearing pins, 12. second bearing pins, 13. the 3rd bearing pins.

The specific embodiment

In Fig. 1, the utility model comprises plug housing 10 and is arranged on bracing frame 1 on the plug housing 10.Slippage bar 3 is installed in the through hole of bracing frame 1, can move along through-bore axis, connecting rod 2 one ends are hinged with slippage bar 3 by first bearing pin 11, the other end is hinged with fork 4 middle parts by second bearing pin 12, fork 4 one ends are hinged with bracing frame 1 by the 3rd bearing pin 13, the other end passes in the through hole of latch 5 one ends, the thin bar side of latch 5 is passed end cap 7 centre bores and is nested in the conduit 8, conduit 8 one sides and end cap 7 connect firmly, opposite side and leg 9 sides connect firmly, leg 9 sides and bracing frame 1 connect firmly, leg 9 has a lateral support on plug housing 10 confined planes, and the through hole that latch 5 can pass under the guiding of conduit 8 on the leg 9 inserts in the jack of plug housing 10, and spring 6 is installed in the conduit 8, one side withstands on the end cap 7, and opposite side withstands on the cascaded surface of latch 5.

From bracing frame 1, pull out slippage bar 3 outward, latch 5 inserts in the jack of plug housing 10 under the effect of spring 6 power, otherwise, slippage bar 3 is pressed in the bracing frame 1, make fork 4 and connecting rod 2 be in the dead-centre position, then latch 5 overcomes spring 6 power under the effect of fork 4 oscillatory forces, extracts fully from the jack of plug housing 10.

Second embodiment shown in Figure 2 on first embodiment basis symmetric arrangement connecting rod 2, fork 4, latch 5, end cap 7, spring 6, conduit 8, and hinged second bearing pin 12 of hinged the 3rd bearing pin 13 of fork 4 and bracing frame 1, fork 4 and connecting rod 2, its structure is identical with embodiment 1.
