Description
Technical field
The present invention relates to billiard table field, espespecially a kind of billiard table being applied to the environment that jolts.
Background technology
At present, playing billiard ball is all settle billiard table on the ground, to ensure that billiard table remains level.If but people will hinder the enforcement of dozen this recreation of billiard ball and carry out when trip is played by ship, and seldom have the billiard table device on ship both at home and abroad.
Very high to the requirement of level during owing to playing billiard ball, so adjustment becomes the key technology main points addressed this problem in real time.Common billiard table is all generally use on the ground, the stable level being convenient to Billiards table on ground, and the requirement of such billiard table environment is to external world lower.And if comparatively jolt or the platform of less stable time, such as travel in afloat cabin, billiard table then can not keep balance, thus can not normally use, this has had larger restriction to carrying out of this recreation of billiard ball, and therefore the lower billiard ball of beating of varying environment make the requirement of the stationarity of environment to external world higher.
In order to solve the problem, those skilled in the art have developed the billiard table being applied to the environment that jolts, such as, be applied to billiard table on seafaring ship, and these billiard tables are mainly provided with for regulating desktop to be the levelling device of level.But the response speed that these levelling devices existing have is comparatively slow, and some life cycles are shorter, need often to change transmission device; Then there is certain potential safety hazard or cause certain pollution to environment in some levelling devices, comprehensive various scheme is known, and often kind of scheme has unsatisfactory shortcoming place.
Problem existing for above-mentioned existing levelling device shows, is still badly in need of wanting a kind of appearance that still can keep the billiard table of desktop level under the environment that jolts.
Summary of the invention
The object of this invention is to provide a kind of billiard table being applied to the environment that jolts, its can under the environment that jolts also can quick adjustment billiard table desktop keep level.
