Description of drawings
Figure l is the utility model structural representation.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is done further detailed explanation.
As shown in the figure: a kind of lamp box painting canvas tensioning system is characterized in that: described tensioning system is made up of fixed block 5 and movable block 2, and fixed block 5 is provided with Baltimore groove 52; The one side of Baltimore groove 52 is provided with first tooth bar 3; Movable block 2 places in the Baltimore groove 52, is provided with 3,31 interlocks each other of second tooth bar, 31, two tooth bars with respect to first tooth bar 3 on the movable block 2; The groove 41 at movable block 2 middle parts; Groove 41 inside surfaces are provided with raised line 42, and groove 41 is provided with the briquetting 4 that cooperates with it, and briquetting 4 inserts and clamps painting canvas 1 in the groove 41.
Be clearance fit between described briquetting 4 and groove.
Described fixed block 5 is provided with slide rail 51, and fixed block 5 is through boss 61 fixed installations at slide rail 51 clamping lamp box edges 6.
Lamp box configuration two covers of described painting canvas tensioning system are up and down or left-right symmetric is installed on the frame 6 of lamp box.
A lamp box configuration of described painting canvas tensioning system quadruplet is up and down and left-right symmetric is installed on the frame 6 of lamp box.
Principle of work: when lamp box is installed; The both sides of painting canvas 1 or four limits (are looked the tricks that tensioning system is provided with and decided; Less needs of painting canvas respectively are provided with a cover in two directions up and down and get final product, if painting canvas is excessive, can around painting canvas, be provided with one and overlaps tensioning system) put into the groove 41 at movable block 2 middle parts; Use briquetting 4 to insert and clamp painting canvas 1 in the groove 41; Groove 41 inside surfaces are provided with the groove 41 that is provided with on raised line 42 and the briquetting 4 and can play fastening and the increase function of friction, guarantee the tensile force of painting canvas 1.Then 1 any movable block 2 on one side of painting canvas is placed the Baltimore groove 52 of fixed block 5; The one side of Baltimore groove 52 was provided with and was provided with the 31 mutual interlocks of second tooth bar with respect to first tooth bar 3 on first tooth bar 3 and the movable block 2 and fixes this moment, then with the movable block 2 of its opposite side in the same way by in the Baltimore groove that is lowered to fixed block 5 52.Because described tooth bar is for being provided with multistage teeth, in the process of firmly pushing movable block 2, its tooth bar will produce auto-lock function, the distance of movable block 2 every propelling one teeth, i.e. and lockable one segment distance is until painting canvas 1 complete tensioning.When needs are dismantled painting canvas 1, only need to use special-purpose instrument, 3,31 mutual disengagings of tooth bar of 5 of movable block 2 and fixed blocks are got final product.Compare with conventional lightbank, the utlity model has simple in structurely, installation and removal are convenient; Needn't carry too many instrument; Do not destroy painting canvas and lamp box, painting canvas surfacing non-ripple, the operator does not need the very knowledge of specialty; Can reduce advantages such as advertising company's operating cost, be suitable for promoting widely.
