Abstract
The utility model discloses a roll screen which comprises a storage bin, a support rod, a hanging strip, an exhibit roll and a sleeve. The sleeve is connected in the storage bin in a rotating mode, a spring rod in the sleeve can extend out the storage bin through a connection part, the lower end of the exhibit roll is fixed on the sleeve, the upper end of the exhibit roll is fixed on the hanging strip, and the hanging strip is supported and fixed on the storage bin through the hanging strip. Under the situation without replacing a roll screen aluminum main body, a mandrel can be replaced quickly. The roll screen reduces using cost, is simple to operate and prolongs service life.
Description
Technical field
The utility model belongs to a kind of advertising device, particularly a kind of post stand advertising device.
Background technology
In exhibition or indoor advertisement, very high on the utilization rate of well-known post stand, it has played very large effect for we advertise, but post stand uses as demonstrating apparatus, spoilage also goes up very high, and the spoilage of post stand more than 90% is because post stand base core pipe damages because use for a long time.
Common post stand understructure and working method: be generally bottom integrated formula structure, fixing with screw, rivet or bolt etc., can not free-handly dismantle, in the bottom reel is arranged, in spring is arranged, the time spent does not use when needing picture is pulled out with in the advertisement picture rollback reel, just supports in the back and can use with a rod.
Changing in the market the core post stand has two kinds to put into form, and the one, put into the core pipe from post stand base side; The 2nd, directly put into from the post stand base top, but these two kinds of forms all exist no small defective, not only take inconvenience, and the bad control of picture angle.
The utility model content
The purpose of this utility model is the deficiency that solves above-mentioned technology, proposes a kind of in the situation that do not change post stand aluminium main body, can the quick-replaceable mandrel, and the reduction use cost, simple to operate, the post stand that increases the service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of post stand, comprise storage warehouse, support bar, hanging strip, showpiece volume and sleeve, described sleeve is rotationally connected with in the described storage warehouse, spring base in the sleeve stretches out outside the storage warehouse by web member, the lower end of described showpiece volume is fixed on the described sleeve, and its upper end is fixed on the described hanging strip, and hanging strip is fixed on the storage warehouse by they sup-port.
Further, described post stand also is provided with the ratchet of ratchet and cooperation, described ratchet is rotationally connected with the side of described storage warehouse, and fix with the web member of described spring base and to be connected, described ratchet is fixed on the side of described storage warehouse through detent pin, one end of ratchet is through return unit and the engagement of described ratchet, and the other end is provided with the clutch button.
Further, the outside of described ratchet is provided with the knob of cooperation, between knob and the ratchet by the bayonet lock connection that is fixed.
Further, described storage warehouse side is side cover, and side cover is fixedly connected with storage warehouse.
Adopt above-mentioned technology, the beneficial effects of the utility model have:
1, in the situation that do not change post stand aluminium main body, can the quick-replaceable mandrel, reduce use cost, simple to operate, the post stand that increases the service life.
2, the utility model fixes the clutch structure that is connected with ratchet and pawl at the web member of spring base, both can apply torsion to sleeve, also can liberate spring torsion, has solved sleeve torsion and can't discharge the series of problems that brings.
3, not only can prolong the physical life of spring, also can improve the security of whole sleeve.
4, the outside of ratchet is provided with the knob of cooperation, thereby can apply torsion to sleeve easily.

Embodiment
The utility model is described in further detail below in conjunction with specific embodiment, but the utility model is not limited to following examples.
Shown in Fig. 1-7, a kind of post stand, comprise storage warehouse 1, support bar 2, hanging strip 3, showpiece volume 4 and sleeve 5, sleeve 5 is rotationally connected with in the described storage warehouse 1, spring base 6 in the sleeve stretches out outside the storage warehouse 1 by web member 7, the lower end of described showpiece volume 4 is fixed on the described sleeve 5, and its upper end is fixed on the described hanging strip 3, and hanging strip 3 supports by support bar 2 and is fixed on the storage warehouse 1.
The ratchet 9 that post stand also is provided with ratchet 8 and cooperates, described ratchet 8 is rotationally connected with the side 10 of described storage warehouse 1, and fix with the web member 7 of described spring base 6 and to be connected, described ratchet 9 is fixed on the side 10 of described storage warehouse 1 through detent pin 11, one end of ratchet 9 is through return unit 12 and described ratchet 8 engagements, and the other end is provided with clutch button 13.
The outside of ratchet 8 is provided with the knob 14 of cooperation, between knob 14 and the ratchet 8 by bayonet lock 15 connection that is fixed.Storage warehouse 1 side 10 is side cover, and side cover is fixedly connected with storage warehouse 1.Described return unit 12 is a back-moving spring, the structure of sleeve 5 comprises bobbin, spring base, spring, pipe plug and spacing pad as shown in Figure 2, and described pipe plug is fixedly installed on an end of bobbin, spring base is positioned at pipe plug, both can be movable relatively, and spring housing is located at outside the elastic rod, and an end pipe plug of spring is on spring base, the other end is fixed on the pipe plug, one end of spring base fixes in ratchet by web member and connects, and the other end is fixed with spacing pad, and spacing pad is located in the bobbin.
This novel principle is: before post stand uses, first the showpiece volume is fixed on the sleeve, coming to apply torsion to sleeve by the rotation knob, torsion passes through bayonet lock successively, ratchet, web member is transferred on the interior spring of sleeve, torsion applies in the process, showpiece is wound on the sleeve, because sleeve can't turn round under the effect of ratchet in the other direction, thereby between sleeve and storage warehouse, form unidirectional motive force, after extracting the showpiece volume out, the sleeve of storage silo is fixed on the hanging strip of support bar top, to realize the display function of post stand, after showing end, showpiece twists in and again is wound under the sleeve torsion on the sleeve, then utilizes the clutch button that ratchet is dialled from ratchet, spring in the sleeve is turned round under the effect of self torsion, thus retracting spring torsion.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and obviously, those skilled in the art can carry out various changes and modification and not break away from spirit and scope of the present utility model the utility model.Like this, if of the present utility model these revise and modification belongs within the scope of the utility model claim and equivalent technologies thereof.
