Description
[technical field]
The utility model relates to the display device technology field of the use such as advertisement, poster, specifically a kind of spring pitch of the laps structure with post stand.
[background technology]
Post stand is the occasions such as current meeting, exhibition, sale publicity, and frequency of utilization is the highest, also one of modal portable exhibition tool.A reel is arranged at the general bottom of post stand of the prior art, inside has spring, and the used time is not by advertisement picture rollback reel.Need when use, cloth cover is pulled out, support in the back and can use with a rod.But existing post stand spring fixed end is not or not post stand body is directly connected with cover plate, and while causing using, variable factor is many, and stability is compared poor with tightness.
On existing market, the structure of common post stand spring structure is that spring is fixed on axle by glue etc., spring cannot be extended, when circle around time spring cannot extend, make the inside torsional deformation of spring, reduce the fatigue resistance of spring, lateral thrust exists all the time, and the larger lateral thrust of torsion is just larger, has internal cause power; In the time being subject to external impacts, spring fixed end poor stability, one works inside and outside adding with joint efforts, easily produces the problem that spring force is escaped.
[utility model content]
The utility model is not directly connected with post stand body deficiency and defects such as causing spring poor work stability in order to overcome post stand spring fixed end in prior art exactly, a kind of novel structure is provided, safe and reliable, can effectively solve the spring pitch of the laps structure for post stand of the problems such as spring force escape, comprise stationary shaft, axostylus axostyle, end casing, shaft rod upper sleeve is provided with around coil spring, end casing is provided with tie point and axis hole, described spring pitch of the laps structure is located in the cylindrical shell of post stand, described stationary shaft one end is provided with through hole and pickup groove, axostylus axostyle and fixing respectively in this through hole and pickup groove around coil spring, spring is fixedly connected with stationary shaft, the stationary shaft other end is provided with projection, on this projection shape and end casing, the draw-in groove shape of tie point matches, thereby stationary shaft is fastened on end casing and by pivot pin and is located.
Described tie point is the draw-in groove of non-round structure.
One end that described stationary shaft is connected with end casing is provided with a round bump, round bump center offers the first through hole, round bump is provided with four extension blocks along excircle, described extension block is uniform along the excircle of round bump, thereby the shape of the tie point on end casing and this projection cube structure matches stationary shaft is fastened on end casing; Stationary shaft offers the second through hole with the center, one end being connected around coil spring and axostylus axostyle, and the diameter of the second through hole is greater than the diameter of the first through hole, offers a circle pickup groove along the second through hole outer ring.
Between the second described through hole and pickup groove, form a circle convex edge, in coil spring is fastened on pickup groove and with convex edge, be fixedly connected with.
Described axostylus axostyle one end is connected with end casing by stationary shaft, and the axostylus axostyle other end is flexibly connected with coupling shaft one end, and the coupling shaft other end is connected on the cylindrical shell body of post stand.
The utility model compared with the existing technology, its advantage is that the utility model followed the characteristic of spring itself, one end of spring is directly connected with fixing stationary shaft on the cover board, directly be fixed on thus on post stand body, make tightness and the good stability of structure itself, length free-extension when the other end of spring rotates, do not stress thereby reached laterally, thrust is zero, keep state of nature, thereby solve the important quality problem that when post stand is subject to external impacts, spring force is escaped, there is safe and reliable performance guarantee.

[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in further detail, and the structure of this device and principle are very clearly concerning this professional people.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model comprises stationary shaft 3, axostylus axostyle 1, end casing, is arranged with around coil spring 2 on axostylus axostyle 1, and end casing 4 is provided with tie point and axis hole, and spring pitch of the laps structure is located in the cylindrical shell of post stand.Center, stationary shaft one end offers the second through hole 7, offers a circle pickup groove 8 along the second through hole outer ring, axostylus axostyle and fixing respectively in this through hole and pickup groove around coil spring 2.Axostylus axostyle one end is connected with end casing by stationary shaft, and the axostylus axostyle other end is connected on the cylindrical shell body of post stand by coupling shaft.The stationary shaft other end is provided with a round bump, round bump center offers the first through hole, round bump is provided with four extension blocks along excircle, described extension block is uniform along the excircle of round bump, thereby the tie point on end casing 9 matches stationary shaft is fastened on end casing with the shape of this projection cube structure.Wherein, the diameter of the second through hole is greater than the diameter of the first through hole.
In use, give in advance the torsion of a quantification of spring, the size of torsion is by turn around certain number of turns, and spring drives drum movement, and the length that the number of turns of cylinder is launched is slightly larger than the size of shot length.Discharge torsion rolling cylinder by spring and tighten up picture, tighten up spring by pull-out picture, reach the object of showing picture.Being rotated and producing after torsion around coil spring in the utility model, spring diameter attenuates, and length is freely extended elongated, meets correct stressed rule and the direction of spring, the in use reasonable stress to spring, safety, has solved the problem that when post stand is subject to external impacts, spring force is missed.
