Vertical lift mechanism or push to open system for a cabinet lid

hinges

I'll try and describe as best I can. I have a simple wooden cabinet, in which is a rack hifi system.

The front of the cabinet is a solid oak overlay door that swings out.

The top of the cabinet, the top surface of the cuboid if you like, is not yet affixed in any way.

Immediately underneath the top surface (again solid oak, about 2cm thick) , is a gramophone with a plastic dust cover lid-box…which for now I don't want to dispose of.

In order to use the gramophone, for the time being I have to remove the wood lid , open the plastic lid, play a record.

What I would like to be able to do this is use that wooden surface for some ornaments, and be able to push the lid or somehow activate the lid so that it rise vertically upwards and create space for me to reach in and use the gramophone.

There is space for four vertical struts in each corner and to be contained within the cabinet.

What sort of mechanism(s) would allow the lid to gently rise upwards by about 50cm, while the lid stays horizontal? I was thinking of just using a TV lift with diagonal brackets supporting the oak lid, but this looks rather expensive, and doesn't seem to offer a "push the lid down and it will slowly pop out" mechanism. Is there something simple involving eg: latches and gas struts that is available?

Thank you in advance for any help.

I would consider two threaded rods in the back two corners that are rotated together and can drive up the lid.

They probaly need to be about 1/2” diameter as the lid length will cause a bending moment on the rods, unless you have extra sliding rods as well.

For initial testing a car wiper motor may be sufficiently slow - but that is easy to adjust when using toothed belts...
