Description

The cloth cover folding table

Technical field

The utility model is a kind of folding table, and specifically desktop is the folding table of weaving cloth cover, is applicable to that the field portably uses.

Technical background

The folding table kind is more in the market, and desktop mostly is wooden or plastics are made.After desk was folding, volume carried inconvenience greatly.And adopt the cloth cover folding table, and though solved the problem that volume after folding is carried inconvenience greatly, existing desk, to launch back desktop tension more loaded down with trivial details, the tightening force deficiency, and the desktop bearing capacity is little, and tableware and the amusement article placed on the table such as easily fall at shortcoming.

Summary of the invention

The utility model purpose is to disclose a kind of cloth cover folding table, overcomes the problem of the loaded down with trivial details pressure-bearing deficiency of the tension of cloth cover folding table expansion in the market, and its advantage is that the desk unfolded is simple to operate, and volume after folding is little easy to carry.It is stable that desk launches after-poppet, and the desktop carrying is big, and article are placed stable.

Its composition of the utility model comprises desktop, bracing frame, anti-torsion bar and the tight mechanism of bloated zip; It is characterized in that: described desktop is the enough weaving cloth desktops 3 of tensile strength, and four angles of its square desktop and the upper end of four oblique trombone slides 4 connect into four spikes; Described bracing frame is by oblique trombone slide 4, the symmetrical chiasma slant-pull structure that stay pipe 5 and fall way 10 connect to form, tiltedly trombone slide 4 adopts four steel pipes that sufficient intensity is arranged, and by the hole, garden at half place of steel pipe, respectively four steel pipe equal portions is connected between waist hoop 9 and the center ring 8 with screw.Fall way 10 is installed in the hole of center ring 8, and an end of four stay pipes 5 is connected on the fall way 10, and the other end is connected with oblique trombone slide 4, and its position is connected half of cloth desktop 3 places, formation umbrella frame structure in oblique trombone slide 4 and waist hoop 9 junctions to oblique trombone slide 4.Anti-torsion bar 12 1 ends connect fall way 10, and the other end inserts 13 li of the casing supports that are installed on the oblique trombone slide 4.The tight mechanism of described account zip is made of screw thread jack 7, gib block 11 and clamp 14.Screw thread jack 7 is connected in the first half of fall way 10.Fall way 10 tops are positioned at 3 times centers of desktop, the gib block 11 of band draw-in groove is housed on the fall way 10 and is installed in the clamp 14 of center ring 8, and when fall way 10 moved downward, clamp 14 entered in gib block 11 draw-in grooves, make the fall way 10 can not resilience; Screw thread jack 7 is equipped with handwheel 6; Clamp 14 and handle 15 are connected to the following and side of center ring 8, and clamp 14 is stuck on the gib block 11, and contact with handle 15.

Oblique trombone slide 4 described in the utility model is being removable minute body structures near center ring 8 lower ends.The oblique trombone slide Lower Half that unloads after folding can be inserted in the space of center ring 8 and waist hoop 9.

The specific embodiment

As shown in FIG., enhancing ring 2 is fixed on 1 in cloth desktop 3 centers, and stay pipe 5 two ends are connected with fall way 10 with oblique trombone slide 4, form the umbrella frame structure.Anti-torsion bar 12 1 ends are connected on the fall way 10, and the other end inserts 13 li of casing supports on the oblique trombone slide 4.Screw thread jack 7 is connected in the first half of fall way 10.Tiltedly trombone slide 4 is connected between center ring 8 and the waist hoop 9 by equal portions respectively.Gib block 11 is fixed on the fall way 10.Clamp 14 is stuck on the gib block 11, and contacts with handle 15.Four angles of square cloth desktop 3 are connected to oblique trombone slide 4 tops, form four spikes, and four lower margins are corresponding one by one with landing.In Fig. 5, the clearer the utility model locations of structures relation of having showed of 3-D view.

The oblique trombone slide 4 of the utility model desk support adopts four steel pipes that sufficient intensity is arranged, and by the hole, garden at half place of steel pipe, respectively four steel pipe equal portions is connected between waist hoop 9 and the center ring 8 with screw.Four angles of square cloth desktop 3 are separately fixed at an end of steel pipe.When launching desktop, four steel pipes rotate to four different directions respectively, and desktop launches.Four steel pipes form the support that symmetrical chiasma tiltedly draws.An other end of steel pipe forms 4 ground, and support has fabulous stability.Fall way 10 is installed in center ring 8 holes, and an end of four stay pipes 5 is connected on the fall way 10, and the other end is connected with oblique trombone slide 4, and its position is connected half position at desktop place to oblique trombone slide 4 tops in oblique trombone slide 4 and waist hoop 9 junctions.The desk support forms the umbrella frame structure.In order to strain the cloth desktop, with fall way 10 tops of pronation promotion desktop center, because stay pipe 5 thrust, fall way 10 can produce very big moment of torsion, influences support and launches.Support launches anti-simultaneously torsion bar 12 and plays a role thereupon, prevents that lifting official 10 moment of torsion from producing, and support launches smoothly.When being installed in the gib block 11 that has draw-in groove on the fall way 10 and moving downward with fall way 10, the clamp 14 that is installed on the center ring 8 enters in the draw-in groove, and fall way 10 is stuck can not resilience.Because the active force of palm is little, desktop tentatively is tightened up.In order to make desktop carrying bigger, reach user mode, as long as rotation is installed in the handwheel 6 on the screw thread jack 7 on the fall way 10, desktop begins evenly stressed, desk launches to finish when spacing when rotating to.Desk is folding very simple, as long as the handwheel on the screw thread jack 76 is screwed to original position, press with the handle 15 that a hand will be installed on the center ring 8, the clamp 14 that is stuck on the gib block 11 is open at once, fall way 10 upwards resiliences, desktop is in relaxed state, and handle 15 is not pressed and is unclamped, upwards draw enhancing ring 2 on the desktop with the another hand, desktop and support draw in.

Oblique trombone slide 4 described in the utility model is being removable minute body structures near center ring 8 lower ends.The oblique trombone slide Lower Half that unloads after folding can be inserted in the space of center ring 8 and waist hoop 9.Desktop and support draw its length of back in to be shortened greatly, more conveniently carries and deposits.
