Abstract
The utility model belongs to a luminous advertising device which comprises a supporting frame; the supporting frame is provided with a tray which can relatively move, and the periphery of the tray is uniformly provided with canvas holding members which are fixed on the supporting frame. Because the utility model is provided with the tray which can relatively move and arranged on the supporting frame, and a plurality of canvas holding members are arranged on the supporting frame around the tray, the canvas holding members can hold each hem of the canvas, then the tray can impel a picture frame to move, thereby, the picture frame is tightly close to the canvas. Because the canvas holding members are distributed around the tray, the canvas can be tensioned uniformly and smoothly.
Description
Technical field
The utility model belongs to luminous advertisement.
Background technology
The lamp box advertisement is a kind of common advertising device, it normally is made up of picture frame and the painting canvas that has an air brushing content, painting canvas is being installed in the process of picture frame, make painting canvas tighten and evenly smooth be very important, otherwise painting canvas is lax, fold, not only influence attractive in appearance and advertising results, and come off easily.At first, people adopt by hand painting canvas are tightened, fix, but for large-sized painting canvas, manually-operated effect is undesirable.
November 15 nineteen ninety-five, the disclosed patent No. was that 94243894.9 Chinese utility model patent discloses a kind of lamp box painting canvas tensioning system, as shown in Figure 1, it comprises housing 1, lining 6, also have set screw 2, hold-down nut 3, tighten dop 4, shaft tip 5, the protruding tip 7, keeper 8, the hold-down nut 3 and the protruding tip 7 are fixed on the housing 1, set screw 2 is spirally connected with hold-down nut 3, and by keeper 8 location, keeper 8 with tighten dop 4 and join, tighten in the dop 4 and wear lining 6 by shaft tip 5, lining 6 is drawn from the opening part of tightening dop 4, and is pressed on the protruding tip 7.During use, by screwing set screw 2, move lining 6 is tightened thereby drive the edge of tightening dop 4 and lining 6.
The complex structure of above-mentioned tensioning system, the also necessary hold-down nut of housing itself, and complex structure, each device all will be operated separately, need many people manually-operated simultaneously, efficient low and also act on painting canvas everywhere the size of power be difficult to identically, the direction of tightening power is inharmonious, thus painting canvas be difficult to accomplish when tightening smooth evenly.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, provide a kind of simple in structure, automaticity is high, the painting canvas tensioning system that painting canvas evenly entirely can be tightened.
The utility model is achieved in that it comprises support, is provided with on the support evenly to be provided with and the fixing painting canvas holder of support in the pallet periphery relative to its pallet that moves.
Above-mentioned pallet is connected with rack-mount drive unit; Drive unit can be hydraulic cylinder or lifting jack; Can also be provided with on the support and limit the guiding mechanism that the pallet straight line moves; Described guiding mechanism can be for being fixed on the longitudinally guiding cover on the support, and the bottom of pallet is passed this orienting sleeve and is connected the output terminal of drive unit.
Picture frame can directly be placed on the pallet, also can connect the picture frame carriage that is complementary with various picture frames in the upper end of pallet, and picture frame is placed on the picture frame carriage; The painting canvas holder is the clip that has groove, the hinged clamp jaw of one side.
The utility model is owing to have support, being provided with on the support can be relative to its pallet that moves, around pallet some painting canvas holders are set on the support, it can clamp the edge of painting canvas, pallet can promote picture frame and moves then, make painting canvas be adjacent to picture frame, distribute around pallet owing to the painting canvas holder again, so painting canvas can evenly entirely be tauted.
Description of drawings
Fig. 1 is the structural representation of prior art painting canvas tensioning system;
Fig. 2 is the utility model front view;
Fig. 3 is the vertical view of Fig. 2;
Fig. 4 is an A shown in Figure 2 place enlarged diagram.
Embodiment
The utility model one-piece construction as shown in Figure 2, it comprises support a, the bottom of support a has three supporting leg a1, the vertically fixing lifting jack b in the bottom center position of support a as drive unit, the middle part fixed guide cover a2 of support a, the fixedly connected push rod b1 of the output terminal of lifting jack b, it passes orienting sleeve a2 and connects pallet c; Support a goes up evenly fixing some painting canvas holder d on surface level around pallet c, and as shown in Figure 3, painting canvas holder d is the clip that top has grooves d 1, the hinged clamp jaw d2 of one side, as shown in Figure 4.
During actual the use, the push rod b1 of original state lifting jack b falls, be attached thereto the pallet c that connects and also be in extreme lower position, can be placed on picture frame e on the pallet c this moment, and their geometric center is alignd, afterwards painting canvas f is layered on the picture frame e, painting canvas f is hung down in the border of picture frame e, clamp the edge of painting canvas f then with painting canvas holder d; Start lifting jack b, push rod b1 is risen, so push rod b1 and pallet c also rise thereupon, and with picture frame e picking-up, owing to being clamped by painting canvas holder d at painting canvas f edge, in the process that picture frame e rises, painting canvas f is progressively tightened, control lifting jack b makes push rod b1 rise to suitable position and stops, and this moment, painting canvas f tightened, and also is evenly smooth; Use at last pulling rivet g with canvas fixing on picture frame, take off picture frame and use and to get final product.In the process that push rod b1 rises, orienting sleeve a2 plays the effect that restriction pallet c straight line moves as guiding mechanism.
Because push rod b1 vertically moves, and picture frame e horizontal positioned and painting canvas holder d evenly arrange around pallet c level, the power that therefore acts on the painting canvas f is uniformly, so painting canvas f must be even, smooth when tightening.Compared to prior art, single job can evenly be tightened painting canvas, has automaticity height, efficient advantages of higher.
Picture frame directly is placed on the pallet in the present embodiment, during actual the use, when shape, size and the pallet of picture frame do not match, can can realize making the picture frame of different shape, size can both use the purpose of this utility model by changing carriage by the picture frame carriage that is complementary with picture frame is set on pallet; In addition, the painting canvas holder can be to removably connect also with support adapt to various picture frames so that change their layout.Lifting jack of the present utility model can replace with other drive unit, and the size of each parts, profile all can design according to actual needs.
