Existing soldier pang platform is typically monolithic construction, say, that arrange a block on common desk.Can see Go out, due between table leg and desk body can not folding storage, therefore, it takes up room.

Chinese patent its publication number CN204671854U provides such a domestic intelligent table tennis table, includes table tennis Billiard table, hydraulic oil container, electric oil pump, flexible billiard table post, check valve, electronic control pressure release valve, pump oil button and pressure relief press button, table tennis Platform central authorities are provided with hydraulic oil container, and hydraulic oil container bottom is provided with electric oil pump, table tennis table corner is equipped with flexible billiard table post, electronic Oil pump is connected with flexible billiard table post by check valve, and flexible billiard table post is connected with fuel tank by electronic control pressure release valve, and table tennis table is right Side is provided with pump oil button and pressure relief press button, and pump oil button is connected with electric oil pump, and pressure relief press button and electronic control pressure release valve connect.

It can be seen that above-mentioned soldier pang Delta is to the parlor that do not takes up space, is applicable to, effect easy to use.But, desk body And the connection between table leg still also exists the problem taken up room.

And, above-mentioned soldier pang platform structure is the most complicated, causes its structure the compactest and cost is higher.

Summary of the invention

The purpose of this utility model is the problems referred to above existed for prior art, it is provided that a kind of compact conformation and the suitability High lift soldier pang ball table.

The purpose of this utility model can be realized by following technical proposal:

A kind of lift soldier pang ball table, including table, it is characterised in that also include base, elevating lever and guiding mechanism, on Stating elevating lever top axial to be connected on table, described base has energy in table bottom and between elevating lever lower end and base The governor motion of regulation elevating lever height, above-mentioned guiding mechanism is between table and base and under the effect of guiding mechanism Table can stable upper and lower translation.

Under the effect of governor motion can relative position between stable regulation table and base, thus adjust the height of table Degree, it is adaptable to the user of various different building shape.

Under the effect of guiding mechanism, it is avoided that desk body rotates relative to base, improves its stability in use.

In above-mentioned lift soldier pang ball table, described governor motion include adjustment barrel, above-mentioned adjustment barrel be tubular and Adjustment barrel lower end is connected on base, described adjustment barrel is the most axially fixed with regulation axle, described regulation axle is fixed with gear, Above-mentioned elevating lever sidepiece is fixed with tooth bar, and said gear is meshed with tooth bar.

During rotating gear, owing to tooth bar is connected on adjusting rod, therefore, adjusting rod can be along with moving up and down.

Certainly, having inserted link in adjustment barrel, axially have hole, some location on adjusting rod along it, inserted link is inserted in location Just can make to be formed between adjusting rod and adjustment barrel location after at hole.

In above-mentioned lift soldier pang ball table, the end of described regulation axle has handwheel.

Regulation axle can easily be rotated by handwheel, thus stabilized zone moving gear rotates.

In above-mentioned lift soldier pang ball table, also there is in described adjustment barrel fairlead ringwise, above-mentioned fairlead It is enclosed within elevating lever.

Under the effect of fairlead, it is avoided that elevating lever directly contacts with adjustment barrel.

In above-mentioned lift soldier pang ball table, the quantity of described fairlead is two, between said two fairlead also Having tubular spacer, above-mentioned two fairlead bears against at the upper and lower end parts of spacer.

In above-mentioned lift soldier pang ball table, the outside of described fairlead and spacer is all resisted against inside adjustment barrel.

In above-mentioned lift soldier pang ball table, the internal diameter of described spacer is more than fairlead internal diameter.

In above-mentioned lift soldier pang ball table, described gear is positioned at inside spacer to be located.

Fairlead stably contacts with elevating lever, meanwhile, can dodge elevating lever at spacer so that be positioned at the gear energy of spacer Stable is meshed with tooth bar.

In above-mentioned lift soldier pang ball table, described adjustment barrel upper end has end cap, and above-mentioned end cap is resisted against fairlead On.

Set and stable being positioned in adjustment barrel of spacer it is directed under the effect of end cap.

In above-mentioned lift soldier pang ball table, the edge of described end cap has the button edge of protrusion, and described button is along button It is combined in adjustment barrel upper end.

The stable connexon adjustment barrel upper end of end cap can be made by buttonhole.

In above-mentioned lift soldier pang ball table, have to have between described regulation axle and adjustment barrel and can make regulation axle The one-way mechanism of unidirectional continuous rotation.

Effect in check configuration is lowered nodal axisn and can be rotated continuously, it is to avoid when promoting table, table can glide suddenly.

In above-mentioned lift soldier pang ball table, described one-way mechanism includes being connected in the ratchet on regulation axle and hinged Ratchet outside adjustment barrel, also has unidirectional spring, under the elastic force effect of unidirectional spring between described ratchet and adjustment barrel Ratchet has the trend being embedded on ratchet.

Under the elastic force effect of unidirectional spring, ratchet has the trend being embedded on ratchet all the time.

In above-mentioned lift soldier pang ball table, described adjustment barrel also has the clutch that can make ratchet with ratchet clutch Structure.

During table normal hoisting, clutch structure keeps merging phase.When needing to move down table, clutch structure remains open shape State.

In above-mentioned lift soldier pang ball table, described clutch structure includes pull bar, stay cord and card edge, above-mentioned card edge Quantity be two and its be connected in outside adjustment barrel, above-mentioned pull bar the inner is hinged in adjustment barrel, and described pull bar is around its hinged place Can be stuck in after swing at any one card edge, the two ends of described stay cord are respectively fixedly connected with in the middle part of pull bar and ratchet center.

During its hinged place rotating tension bar, by the pull bar stretchy ratchet swung, the ratchet after being pulled departs from Ratchet, now, table can stably move down.

Certainly, it is positioned by the pull bar after swing by card edge.Because this clutch has merging and disconnects two The state of kind, therefore, the quantity on card edge is two, positions pull bar during above two state respectively.

In above-mentioned lift soldier pang ball table, described card is along being connected in adjustment barrel edge.

In above-mentioned lift soldier pang ball table, described card is along including the bar segment one in straight section and bar segment two, above-mentioned bar segment One is inner connected with adjustment barrel, and above-mentioned bar segment two the inner is fixedly connected with bar segment one outer end, and above-mentioned bar segment one is formed in L with bar segment two The card edge of shape.

Such structure comparison material saving, and pull bar stable can be overlapped on Ka Yanshang.

In above-mentioned lift soldier pang ball table, described card is along having elasticity.

In above-mentioned lift soldier pang ball table, described card edge is plastic material.
