Abstract
The utility model discloses a tension spring for an advertising banner. The tension spring comprises a spring body (1), wherein a circular connecting ring (2) is arranged at one end of the spring body (1), and an inverted hook (3) is arranged at the other end of the spring body (1), and has an inverted V-shaped structure. Compared with the prior art, the tension spring has the advantages that the ends, with the circular connecting rings, of the springs are fixedly arranged on four frames of a lamp box through screws when the tension springs are used, the number of the springs is determined according to actual needs, and when the advertising banner is arranged, the inverted hooks of the springs on the four frames are sequentially hooked in hanging holes preformed in the periphery of the advertising banner to tighten the advertising banner under the action of restoring force is more uniform, so that the advertising banner, is difficult to crease and lower in cost, and can be conveniently arranged with one person, and less labor is required; the inverted hooks with the inverted V-shaped structures can be firmly hooked in the hanging holes, and difficultly slide out of the hanging hooks, so that the advertising banner can be more conveniently arranged.
Description
Technical field
The utility model relates to a kind of extension spring, particularly relates to a kind of advertising cloth extension spring.
Background technique
At present, the advertising cloth in advertisement lamp box is in the time putting up or change, and major part is to use sticking double faced adhesive tape or fastening piece to fix; Sub-fraction is used, at advertising cloth two ends, bound edge is set, and is plugged on subsequently on plug-in position reserved on advertisement lamp box; Some is to adopt common standard extension spring, but needs other controlling mechanism to coordinate, otherwise advertising cloth is easily wrinkling.But while using sticking double faced adhesive tape or fastening piece fixing, at least need two workmans just can complete, and advertising cloth easily occurs tilting or wrinkling situation, install also more loaded down with trivial details; And the advertising cloth of pegging graft needs bound edge processing, and corresponding plug-in connection also need to be set in lamp box, cost is higher, and while installing, also needs two other limit to there is no bound edge also to need to be fixed, therefore advertising cloth still exists easily wrinkling situation; And the other auxiliary mechanism that furthers of needs of the standard of use extension spring, use more loaded down with trivial details, and cost is higher, also need when mounted two workmans, because the overhead kick at standard extension spring two ends is because the degree of depth is more shallow simultaneously, in use, be not easy to catch on mounting hole on advertising cloth, once and advertising cloth generation skew or inclination, the extension spring of having caught on easily skids off, therefore need to someone maintain the form of advertising cloth, therefore trouble is installed also.
Model utility content
The utility model provides a kind of required workman less for above problem, the advertising cloth extension spring that simple installation and user cost are lower.
The utility model overcomes the above problems technological scheme used: a kind of advertising cloth extension spring with following structure is provided, it comprises spring body, one end of described spring body is provided with connection annulus, and the other end of described spring body is provided with overhead kick, and described overhead kick is inverted V-shape structure.
Adopt after above structure, compared with prior art, the utility model is because one end of spring body is provided with connection annulus, the other end of spring body is provided with overhead kick, and overhead kick is inverted V-shape structure, in use, the one end that by screw, spring is provided with to annulus is in advance fixed on four frameworks of lamp box, the quantity of spring arranges according to the actual requirements, several when also fixing in advance more, when installing advertisement cloth, successively the overhead kick of the spring on four frameworks is hooked in the default hanging hole of advertising cloth surrounding, now advertising cloth is tightened under the effect of spring restoring force, thereby advertising cloth is tightened up, and the active force of spring is more even, advertising cloth is not prone to the situation of wrinkle, without arranging and draw in mechanism in addition, simple installation, installing advertisement cloth only needs a workman to complete, required workman is less, cost is also lower, and the overhead kick of V-shape structure can hook in hanging hole firmly, and then make overhead kick be difficult for skidding off from hanging hole, the installation of the advertisement of being more convenient for.Therefore, the utlity model has required workman less, the feature that simple installation and user cost are lower.
As improvement, between described overhead kick and spring body, be provided with torsion spring, described torsion spring one end is fixedly connected with spring body, the described torsion spring the other end is fixedly connected with overhead kick, because common spring is between glass and framework, after torsion spring arranges, while making workman in overhead kick pull-up is hooked to the hanging hole in advertising cloth, overhead kick hunting range is larger, make overhead kick be easier to hook in hanging hole, and after in overhead kick is hooking hanging hole, in the more difficult slippage from hanging hole of effect of torsion spring, and then workman's installing advertisement cloth of being more convenient for, also make stability in use of the present utility model better simultaneously.
As further improvement, the axis of described torsion spring is parallel with the axis that connects annulus, just can reduce like this spring and be fixed to rear shared space on framework, and then the installing space of assurance glass, make the thickness of glass (or acrylic) can be thicker, and the intensity of the thicker glass of thickness is better, is not more prone to damaged situation, and then guarantees safety in utilization telephone expenses stability in use of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model advertising cloth extension spring.
Fig. 2 is the structural representation after the extension spring of the utility model advertising cloth is installed.
As shown in the figure: 1, spring body, 2, connect annulus, 3, overhead kick, 4, torsion spring.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
A kind of hand advertising cloth extension spring as depicted in figs. 1 and 2, it comprises spring body 1, one end of described spring body 1 is provided with and connects annulus 2, general connection annulus 2 is by forming with one end bending of spring one, the other end of described spring body 1 is provided with overhead kick 3, and described overhead kick 3 is inverted V-shape structure.
Between described overhead kick 3 and spring body 1, be provided with torsion spring 4, described torsion spring 4 one end are fixedly connected with spring body 1, described torsion spring 4 the other ends are fixedly connected with overhead kick 3, and general spring body 1, connection annulus 2, overhead kick 3 and torsion spring 4 are for there being a steel wire shaping to form.
The axis of described torsion spring 4 is parallel with the axis that connects annulus 2.
When installation, four limits of Lamp case frame by screw be connected annulus 2 fixing uniformly on several the utility model, when allowing, the utility model on two parallel frameworks is corresponding one by one; If the utility model is fixed between glass and framework, in the time of fixing the utility model, overhead kick 3 is hooked to the edge at framework, be convenient to like this installation of later stage advertising cloth.When use, overhead kick 3 of the present utility model on four frameworks is linked up with on the mount hole on advertising cloth successively.
Above embodiment is only preferred embodiment of the present utility model, and the utility model is not limited only to above embodiment and has also allowed other structural change, allly in the utility model rights to independence claimed range, changes, and all belongs to the utility model protection domain.
