Abstract
A roll up banner with adjustable screen angle comprises a roller device and a vertical upright, wherein an insertion hole for the lower end of the vertical upright to insert and a support part for supporting the root of the vertical upright are arranged on the roller device. The roll up banner is characterized in that an adjustment projection is connected with the vertical upright along the length direction in a sliding manner, and a plurality of contact points propped against and matched with the support part are arranged on the adjustment projection along the length direction of the vertical upright; or, an adjustment projection is sleeved on the vertical upright, a plurality of contact points propped against and matched with the support part are arranged on the peripheral surface of the adjustment projection along the circumferential direction, and the distance from the contact points to the axial line of the vertical upright are unequal. By arranging the adjustment projection on the vertical upright, the utility model can adjust the dip angle Alpha of the advertisement screen by varying the distance between the axial line of the vertical upright and the fulcrum (that is the horizontal included angle of the vertical upright) through the up-down moving or the left-right rotating of the adjustment projection. Although the operation is simple and feasible, the effect is remarkable.
Description
Technical field
The utility model relates to a kind of post stand, relates in particular to a kind of post stand of painting canvas adjustable angle.
Background technology
Along with the fast development of market economy, show that equipment becomes an important component part of commercial propaganda gradually, therefore is widely used in the numerous places of client such as market, sales field by businessman, in order to the advertising of product; Or be used for each big show ground by enterprise, to show corporate culture, establish good self-image in the industry.Show that equipment can add the LOGO label with intention, make more eye-catching the representing in public of information, thereby strengthen advertisement function product.
And use the post stand that is of the most general, most convenient in the displaying equipment, itself because take up an area of little, carry with advantage such as easy to use and quite be subjected to liking of people.Described post stand is popular in recent years portable displaying equipment, and its structure mainly is made up of drum apparatus, vertical rod, extension picture bar and advertisement painting canvas, and this drum apparatus comprises the cylinder and the base of a tape wrapping power.During use, the user is pasted on drawing of drum apparatus with advertisement poster cloth lower end and draws, and its upper end and extension picture bar are connected, then, the vertical rod lower end is fixed on the drum apparatus, insert, and on the upper end of vertical rod, fix and hang the picture bar, promptly prop up the advertisement painting canvas at the rear portion by vertical rod, the take-up force of cylinder is tightened the advertisement painting canvas, and the take-up force that leans on cylinder when receiving picture again is with in the advertisement painting canvas income drum apparatus.
Wherein, the grafting fixed form of described vertical rod has two kinds usually: first kind (as shown in Figure 1), the drum apparatus 11 of described post stand is provided with a jack 13, the lower end of vertical rod 12 is plugged in this jack 13, and, a support portion 14 is established in the front side of the root of also corresponding vertical rod 12 on the drum apparatus 11, and this support portion 14 is supported on vertical rod 12 roots as fulcrum 15.Second kind (as shown in Figure 2), the coaxial two sections jack that is provided with on the base of described post stand, first jack 16 of its middle and lower part plays the effect of fixedly vertical rod 12; Second jack 17 on top plays the effect of supporting vertical rod 12, and its hole inwall 18 is equal to above-mentioned fulcrum 15 to vertical rod 12.
Consider people's visual effect, the advertisement painting canvas needed hypsokinesis and horizontal line A to remain on a preferable angle (as inclination alpha among Fig. 3) when designing requirement was the post stand use.And in actual production assembling, it is more and be difficult to avoid influence the uncontrollable factor of advertisement painting canvas actual inclination angle variation, mainly contain following some:
(1), the deadweight of advertisement painting canvas.When vertical rod with after the post stand base is connected, if picture is overweight vertical rod is leaned forward, make the angle of inclination alpha improper;
(2), vertical rod rigidity.The rigidity of vertical rod is crossed the low angle too small that can cause hypsokinesis of advertisement painting canvas and ground to form, and causes the angle of inclination alpha improper;
(3), the gap of each section of vertical rod connection.Because the length of some advertisement painting canvas is longer, need to adopt multistage vertical rod splicing satisfying painting canvas length, but because each section connection the gap can occur unavoidably, and gap length is uncontrollable, and therefore the inclination alpha to painting canvas has caused influence;
(4), initial tension of spring.The post stand cylinder produces by the spring that its in-core is provided with the take-up force of advertisement painting canvas, and the tightening force of this spring is preset, if this pretightning force setting is excessive or too small, all can make the angle of described inclination alpha improper;
(5), the machining precision of vertical rod spliced eye.The precision in this hole has high requirement to the production technology that adds man-hour, and precision keeps the bad angle at inclination angle that not only can make improper, also can cause the angle of each part inclination alpha in one batch of post stand to produce difference.
And the grafting fixed sturcture of vertical rod has determined the horizontal sextant angle of vertical rod to fix in the existing post stand, and is unadjustable, when the inclination alpha of discovery advertisement painting canvas is improper in using, can't remedy its adjustment.Therefore, how to address the above problem, just become research direction of the present utility model.
