This utility model compared with prior art, has advantages below and effect：Provide a kind of floor installation drivers' cab
Latch device, thus being fixed on crane when can continue to after bolt looseness limit drivers' cab, it is to avoid play drivers' cab whole
Body falls and causes casualties, and eliminates potential safety hazard.
Brief description
Fig. 1 is that a kind of floor installation drivers' cab of the present utility model latches the schematic diagram of device.
Fig. 2 is that a kind of floor installation drivers' cab of the present utility model latches the sectional view of device.
Fig. 3 is that a kind of floor installation drivers' cab of the present utility model latches the use state figure of device.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following examples are right
Of the present utility model explain and this utility model is not limited to following examples.
The device as illustrated, a kind of floor installation drivers' cab of the present utility model latches, comprises upper fixing element 1, lower fixation
Part 2 and the bearing pin 3 that latches, upper fixing element 1 is fixed on the upside of cab deck 4, and lower fixture 2 is fixed on the downside of cab deck 4
And it is correspondingly arranged with upper fixing element 1, upper fixing element 1, cab deck 4 and lower fixture 3 have vertical through hole 5, latches
Bearing pin 3 lower end is provided with rotation lock stop 6, and the bearing pin 3 that latches is inserted vertically into vertical through hole 5 spin locking.
Rotation lock stop 6 is the inverted cone of both sides unfilled corner, the inverted cone of vertical through hole 5 cross sectional shape and both sides unfilled corner
Join, vertical through hole 5 lower end of lower fixture 2 is provided with rotary locking hole 7, rotary locking hole 7 be with diameter greater than or be equal to both sides
The circular hole of the inverted cone maximum gauge of unfilled corner.Bearing pin 3 upper end that latches is provided perpendicular to latch the limiting section 8 of bearing pin 3 setting, when
When the bearing pin 3 that latches inserts vertical through hole 5, limiting section 8 is supported on upper fixing element 1 through hole upper end edge and the bearing pin 3 that latches is limited
Position supports.
The vertical through hole upper end of upper fixing element 1 is provided with a die cavity 9 with limiting section 8 form fit, and die cavity 9 leads to vertically
Hole 5 is crisscross arranged at an angle.Die cavity 9 is 90 degree with vertical through hole 5 stagger angle.
Limiting section 8 is fixed on, by bolt 10, bearing pin 3 upper end that latches.The inverted cone lower end vertex rounding of rotation lock stop 6,
The inverted cone upper end bottom surface edge cutting of rotation lock stop 6 is vertically directed cylinder, and the convenient bearing pin 3 that will latch inserts vertical through hole
In 5.
A kind of floor installation drivers' cab of the present utility model latch device use when, by the rotation lock of bearing pin 3 that latches
Stop 6 turns to position corresponding with vertical through hole 5 and inserts in vertical through hole 5, vertically leads to when the bearing pin 3 that latches will submerge completely
When in hole 5, the bearing pin 3 that will latch rotates 90 degree and unclamps the bearing pin 3 that latches, and the bearing pin 3 that latches is under gravity along vertical
Through hole 5 slides downwards, and limiting section 8 just falls in die cavity 9, and rotation lock stop 6 then rotates and is stuck in rotary locking hole 7.
The bearing pin 3 that so latches is connected in die cavity 9 all the time under gravity, even if drivers' cab and loop wheel machine vibrations, latch bearing pin 3
Do not fall out ejection, therefore when installing the cushion pad bolt looseness of drivers' cab, the device that latches can continue to drivers' cab
Keep fixing, cause casualties thus having avoided drivers' cab and integrally having fallen, eliminate potential safety hazard.
Above content described in this specification is only to this utility model example explanation.This utility model
