Embodiment

Below in conjunction with drawings and Examples, the folding frame of locating of the present utility model is described in further detail.

Refer to shown in Fig. 3 to Figure 11, the utility model embodiment's located for folding frame comprises: a support body 20, by the four pole 21 pivot joint four fork arm groups 22 that are arranged in rectangle, formed, be mounted slidably one group of slide block 23 of establishing hole on each pole 21, the other end of each pole 21 arranges respectively a pulley 24, each fork arm group 22 is arranged at respectively between two poles 21, each fork arm group 22 is comprised of two hinged arms 221 intersection pivot joints, the two ends of each hinged arm 221 are articulated in respectively pole 21 and this slide block 23, see through the pivotable of hinged arm 221 and the slippage of each slide block 23 on this pole 21 make each pole 21 can be relatively near or away from, wherein on this pole 21 one first positioning hole 213 and one second positioning hole 214 be set, and slide block 23 on the pole 21 of this first positioning hole 213 and the second positioning hole 214 is set to have one group and establishes hole 231, and location unit, be located at and there is this group and establish on the slide block 23 in hole 231, and this location unit 30 comprises one and determines part 31, a plug-in unit 32, a spring 33, an external member 34 and an operation piece 35, should determine part 31 establish 231 position, hole for nut relative this group and be fixedly installed on this slide block 23, these plug-in unit 32 two ends are respectively one and insert fixed end 321 and a band moved end 322, and there is a shoulder 323 between the two ends of this plug-in unit 32, this external member 34 is for hollow-core construction and have a head end 341 and a fixed end 342, this fixed end 342 has a holding part 343, this holding part 343 has a low face 344 that leans on, this band moved end 322 wears this spring 33 and penetrates in this holding part 343, the two ends of this spring 33 are abutted against respectively in this shoulder 323 and this abutment facing 344, and the band moved end 322 of this plug-in unit 32 passes this head end 341 and is fixedly connected with this operation piece 35, and this location unit 30 sees through the fixed end 342 of this external member 34 again and is fixed in this group and establishes hole 231.

More than for the utility model, can locate overall structure and the significant condition of folding frame, and its use state as shown in Figure 3, this support body 20 is illustrated in figure 3 the state trailed, the slotting fixed end 321 of the plug-in unit 32 of this location unit 30 is inserted and is positioned this second positioning hole 214, makes this slide block 23 be restricted location.

And when needs are taken in this support body 20, seeing through these operation piece 35 these plug-in units 32 of drive of drawing moves to the direction away from the second positioning hole 214, when moving, this plug-in unit 32 sees through this shoulder 323 these springs 33 of compression, after this second positioning hole 214 is deviate from the slotting fixed end 321 of this plug-in unit 32, this slide block 23 loses the strength of location, the pivot that the user just can see through each fork arm group 22 holds together and makes each pole 21 close, and each slide block 23 is along pole 21 slippages, finally become the state that closes up of taking in, when each slide block 23 slides onto this 213 position, first hole, just can easily quote the strength of this operation piece 35, this spring 33 resets, corresponding this first positioning hole 213 that inserts in the slotting fixed end 321 of this plug-in unit 32 forms location, from the above, the utility model is to form location in upholding to use or close up under receiving state, under the use state, can avoid closing up improperly, improve stability and the Security used, and do not use in closing up that state is next can reduce occupied space, improve the convenience of taking in.

In addition, as shown in Figure 9, the two ends of one Returnning spring 50 are fixedly installed on respectively on this pole 21 and slide block 23, this Returnning spring 50 hold power stretches when this support body 20 closes up state for taking in, and the location of removing this location unit 30 is while upholding this support body 20, these Returnning spring 50 elastic resets auxiliary each fork arm group 22 Quick extensions are split into as the use state, and as shown in figure 10, the convenience of use is high; Moreover each pole 21 of above-described embodiment, fork arm group 22 are all to using square tubular as explanation, so its tubular aspect also can be set to circular pin as shown in figure 11, can reach too and the identical purpose of above-described embodiment and effect.

The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solutions of the utility model content, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
