Outer fix distinguishes spinning nut.Thus just constitute it is a kind of it is simple in construction, cost is cheap, esy to use, safe and reliable, practical
The strong valve gear roller box hood-opening device of property.In actual applications, the first dop and the second dop is allowed to be respectively at valve gear roller box
Both sides, and make the cutting edge of the first drift and the second drift alignment valve gear roller box main body and upper lid between seam, pass through
The nut of rotating threaded shaft one or both ends drives the first dop and the second dop to be collapsed to centre, passes through the first drift and the second wedge
The cutting edge of iron can strut upper lid.This direction not only smooth operation, safe of uncapping, and can effectively solve existing open
The problem of lid mode is damaged to impacting property of valve gear roller box.
Shown embodiment is made into one to a kind of valve gear roller box hood-opening device of the utility model below in conjunction with the accompanying drawings
Step describes in detail：
Brief description of the drawings
Fig. 1 is a kind of stereogram of valve gear roller box hood-opening device of the utility model；
Fig. 2 is a kind of front view of valve gear roller box hood-opening device of the utility model.
Embodiment
Firstly the need of explanation, the noun of locality such as the front, back, left, right, up, down described in the utility model is simply according to attached
Scheme carry out description, in order to understand, not to the technical solution of the utility model and be claimed scope progress limitation.
A kind of embodiment of valve gear roller box hood-opening device of the utility model as depicted in figs. 1 and 2, including first
Dop 1, the second dop 2, guide rod 3 and leading screw 4.First dop 1 specifically includes starting stave 11 and is fixed on starting stave 11
First drift 12 of lower end, the second dop 2 specifically include the second riser 21 and are fixed on the second drift of the lower end of the second riser 21
22.Allow the cutting edge Relative distribution of the first drift 12 and the second drift 22, and opened up on the riser 21 of starting stave 11 and second
Pilot hole and lead screw hole.Allow guide rod 3 to be passed through from the pilot hole on the riser 21 of starting stave 11 and second, allow leading screw 4 from
Passed through in lead screw hole on one riser 11 and the second riser 21, and guide rod 3 and leading screw 4 is parallel to each other.And the two of leading screw 4
End and the outer fix difference spinning nut 41 in the riser 21 of starting stave 11 and second.
By above structure setting just constitute it is a kind of it is simple in construction, cost is cheap, esy to use, safe and reliable, practical
The strong valve gear roller box hood-opening device of property.In actual applications, the first dop 1 and the second dop 2 is allowed to be respectively at valve gear
The both sides of case, and make connecing between the main body of the cutting edge of the first drift 12 and the second drift 22 alignment valve gear roller box and upper lid
Seam, drive the first dop 1 and the second dop 2 to be collapsed to centre by the nut 41 of the one or both ends of rotating threaded shaft 4, pass through first
The cutting edge of the drift 22 of drift 12 and second can strut upper lid.This direction not only smooth operation, safe of uncapping, and
Can effectively solve the problems, such as that existing mode of uncapping is damaged to impacting property of valve gear roller box.
As embodiment, the utility model allows the first drift 12 and the second drift 22 to use bottom surface as in plane
Side is the structure type of inclined plane, to ensure that the first drift 12 and the second drift 22 during being disturbed to centre receipts, make expansion
