Referring to fig. 1, fig. 2, fig. 3, fig. 8 and fig. 9, the present application provides an embodiment of a floor-pulling type retractable curtain, which comprises an accommodating box 1, a curtain body 2, a lifting mechanism and an adjusting mechanism;

an accommodation box 1 having an opening for pulling out the curtain body 2;

the curtain body 2 is in a rolling state when not used, is rolled in the containing box 1 by winding the curtain shaft 3 and can be pulled out from the opening of the containing box 1;

the lifting mechanism is arranged in the accommodating box 1 and comprises a telescopic lifting rod 4, the end part of the lifting rod 4 is used for being connected with the curtain body 2 so as to lift the curtain body 2, the lifting direction of the lifting rod 4 to the curtain body 2 is a first direction, the axial direction of the curtain shaft 3 is a second direction, the position of the lifting rod 4 in the second direction is adjustable, and the second direction is perpendicular to the first direction;

the adjusting mechanism is arranged on the containing box 1 and is used for contacting the ground, and the adjusting mechanism is used for adjusting the levelness of the curtain cloth shaft 3.

Specifically, when the curtain body 2 is pulled out from containing box 1, then curtain body 2 then is spread, be used for the projection, the effect of carrying pull rod 4 lies in, when carrying pull rod 4 is in the shrink state, can accomodate in containing box 1, when curtain body 2 need expand and stretch out from the opening part of containing box 1, then carry pull rod 4 to extend, drive curtain body 2 stretches out from the opening part, the top that holds box 1 is preferred to be located to the opening that holds box 1, hold box 1 through adjustment mechanism place subaerial time like this, can pull out curtain body 2 from the opening part through carrying pull rod 4, and promote, so that curtain body 2 expandes.

Owing to adopted and held box 1, so this device portable to lifting rod 4 is the telescopic body of rod, adopts this structure to carry to curtain body 2 and draws, and stability is better, is favorable to the more smooth expansion of curtain body 2.

And hold box 1 and can direct contact ground, when the ground is more level, can directly put holding box 1 on ground, can set to the axial of curtain axle 3 and hold box 1 length direction the same, when holding box 1 level, then curtain axle 3 level, and when the ground unevenness, then hold box 1 and directly put on ground and probably cause holding the skew of box 1, and then cause the skew of curtain axle 3, make the curtain body 2 that expandes crooked, the levelness is improper, for solving this problem, the means that this application adopted is, adjustment mechanism has been set up, adjustment mechanism can contact with ground, and then can adjust and hold the distance between box 1 and the ground, adjustment mechanism can set up a plurality ofly, be located respectively and hold the different positions of box 1, can adjust the distance between different positions of holding box 1 and the ground like this, thereby with the skew holding box 1 alignment, also make its curtain axle 3 be in approximate horizontal state promptly, the curtain body 2 that expandes like this also is approximate level thereupon, the curtain that does not take place crooked.

The width of the curtain body 2 is large or small, so that the position of the lifting rod 4 in a second direction perpendicular to the first direction is adjustable.

Specifically, the present application defines that the first direction is a stretching direction of the lifting rod 4, that is, a lifting direction of the curtain body 2 or, as it can be said, a height direction of the curtain body 2, the second direction is perpendicular to the first direction, the second direction is specifically an axial direction of the curtain shaft 3, that is, a width direction of the curtain body 2, and the lifting rod 4 can perform position adjustment along the second direction. When the position of the lifting rod 4 in the second direction is adjustable, the curtain body 2 with different widths can be applied.

This application can adopt two lifting rod 4 through two lifting mechanisms to carry out the form of carrying on simultaneously carrying on the curtain body 2, and the tip of two lifting rod 4 centre gripping respectively or connect the both ends of the upside of curtain body 2 to carry on carrying, because of lifting rod 4 can carry out the regulation of position along the second direction, so can be suitable for the curtain body 2 of different width.

So the beneficial effect of this application lies in, this curtain is including holding box 1, when not, curtain body 2 and carrying mechanism can accomodate and hold inside box 1, ten minutes portable, and curtain body 2 in this curtain adopts and is promoting and descend curtain body 2 through the flexible of carrying rod 4 in carrying mechanism, the means of carrying out carrying through the flexible of the rod-shaped body to curtain body 2 has fine stability, curtain body 2's exhibition is smooth, when curtain body 2's width is great or less, can adjust carrying rod 4 in the ascending position of second direction, because this device can adopt two and carry the mechanism, two carrying rod 4 have simultaneously, the one end of curtain body 2 is connected respectively to two carrying rod 4's tip, carry curtain body 2, when carrying rod 4 is adjustable in the ascending position of second direction, then can hold different width's curtain body 2 between two carrying rod 4, the adaptability has been increased, and when guaranteeing curtain body 2's one end when curtain body 2, the curtain body has the degree of carrying rod 2 and has been adjusted, the regulation that the curtain body has not taken place through the regulation mechanism of the horizontal adjustment and has not taken place the crooked ground and has taken place like this regulation mechanism, the regulation mechanism 2 that the crooked ground of this regulation mechanism can not take place, the crooked adjustment mechanism, the adjustment of this regulation mechanism, it is not take place to take place the certain distance to take place like this.

Referring to fig. 1 and 8, in one embodiment, the number of the lifting mechanisms is two, the curtain body 2 is located between the lifting rods 4 of the two lifting mechanisms, and the lifting rods 4 are electric hydraulic rods driven by a motor 5.

Two lifting mechanisms then have two lifting rods 4, and two lifting rods 4 are located 2 both sides of curtain body, then can realize the pulling to curtain body 2 through synchronous lift, and specifically, lifting rods 4 can adopt electronic hydraulic stem, and it has stronger stability.

Referring to fig. 2, 8 and 9, in one embodiment, in order to adapt to the shape characteristics of the curtain body 2, the accommodating box 1 is provided to be elongated, the curtain body 2 is used for being pulled out from the top opening of the accommodating box 1, the lifting rod 4 is connected with a mounting seat 6, a sliding rail 7 is arranged in the accommodating box 1, the sliding rail 7 is arranged along the second direction, and the mounting seat 6 and the sliding rail 7 are arranged in a sliding manner.
