Description
Technical field
The utility model belongs to steering wheel field, and in particular to it is a kind of can Fast Installation and the screw-type steering wheel freed.
Background technique
The screw-type steering wheel that the current machinery field in China uses generally is connected by the way of semipermanent fixation with undercarriage
It connects.Existing screw type steering wheel is mainly made of lead screw, cylinder, fixing seat, the connection with undercarriage by pin shaft, bolt etc. with
Undercarriage mounting base is fixed, and when needing to free, need to be removed one by one to related retaining element；Existing screw type steering wheel is primarily present
Bulking value is big, and cumbersome deficiency is freed in fixation.
Utility model content
The purpose of the utility model is to provide it is a kind of can Fast Installation and the screw-type steering wheel freed, solve existing lead screw
Formula steering wheel bulking value is big, and cumbersome problem is freed in fixation.
The technical solution of the utility model are as follows: it is a kind of can Fast Installation and the screw-type steering wheel freed, it is characterised in that:
Including fixed cylinder 1, lead screw 2, swivel nut 3, handwheel 4 and fast-coupling device 5；Handwheel is fixed on one end of lead screw, lead screw it is another
End is arranged in fixed cylinder, cooperates in the middle part of lead screw with the swivel nut being fixed in fixed cylinder；Fast-coupling device include shaft 6, under
Frame fixed mounting 7 and bayonet lock；The extension end of fixed cylinder is connect with shaft, and shaft two sides are equipped with symmetrical plane, and undercarriage is fixed
Mounting base is fixedly connected with undercarriage, and undercarriage fixed mounting top is provided with straight trough and arc groove, and the plane of the two sides of shaft passes through
It after straight trough, is rotated by 90 °, is stuck in the circular groove of lower part, linked together by bayonet lock and undercarriage fixed mounting.
It combines and frees the utility model has the advantages that the utility model can complete the quick of screw type steering wheel, improve installation effectiveness.
Detailed description of the invention
Fig. 1 is the structure principle chart of the utility model embodiment；
Fig. 2 is the structural schematic diagram of fast-coupling device；
Fig. 3 is the sectional view along A-A of Fig. 2.
Specific embodiment
To keep the purpose of this utility model, content and advantage clearer, specific embodiment of the present utility model is made
It is described in further detail.
The utility model provide it is a kind of can Fast Installation and the screw-type steering wheel freed, including fixed cylinder 1, lead screw 2, spiral shell
Cover 3, handwheel 4, fast-coupling device 5；
Handwheel is fixed on one end of lead screw, and the other end of lead screw is arranged in fixed cylinder, in the middle part of lead screw and is fixed on fixation
Swivel nut cooperation on cylinder, in realization between undercarriage relative position adjusting；
Fast-coupling device is fixedly connected with undercarriage, and fixed cylinder side is equipped with extension end, is connect with fast-coupling device；
Fast-coupling device includes shaft 6, undercarriage fixed mounting 7 and bayonet lock；
The extension end of fixed cylinder is connect with shaft, and shaft two sides are equipped with symmetrical plane, undercarriage fixed mounting and undercarriage
It is fixedly connected, undercarriage fixed mounting top is provided with straight trough and arc groove, after the plane of the two sides of shaft passes through straight trough, through revolving
It turn 90 degrees, is stuck in the circular groove of lower part, linked together by bayonet lock and undercarriage fixed mounting；For realizing screw type direction
Between machine and undercarriage it is quick combine and free；
The specific work process of the utility model is as follows:
After rotating fast-coupling device shaft is reliably fixed fixed cylinder with undercarriage, rotation hand wheel, lead screw is in handwheel
Lower rotation is driven, the position between upper undercarriage changes, and when needing to release the connection of fixed cylinder and undercarriage, can pass through rotation
The shaft of fast-coupling device is overlapped shaft plane with undercarriage fixing seat installation gap, is detached from shaft from undercarriage fixing seat,
To realize the quick combination of screw type steering wheel and undercarriage and free, the purpose of the relative position in adjustment between undercarriage.
After rotating fast-coupling device shaft is reliably fixed fixed cylinder with undercarriage, rotation hand wheel, screw rod is in handwheel
Lower rotation is driven, the position between upper undercarriage changes, and achievees the purpose that adjust the relative position between upper undercarriage.Work as needs
When the connection of releasing fixed cylinder and undercarriage, shaft plane can be made to fix with undercarriage by 90 ° of shaft of rotation fast-coupling device
Mounting base installation gap plane is overlapped, and when being detached from shaft from undercarriage fixed mounting, moves shaft from mounting base notch
Out, to realize the quick-release of screw type steering wheel and undercarriage.
The utility model drives lead screw rotation by rotation handwheel, change between undercarriage mounting base and restocking mounting base away from
From by fast-coupling device and being installed on down to control the purpose that the relative angle between restocking and undercarriage is changed
Direct quick links of mounting base on frame and the quick purpose for combining and freeing for freeing achievable steering wheel and undercarriage.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
