The specific embodiment:

At first, see also Fig. 2,3, shown in 4, the utility model system is by a joint 20, a top cover 30 and a vertical rod 40 that articulates, two poles 41 are formed, one uprise 21 is arranged in this joint 20, uprise 21 has a hole 211, this uprise 21 can penetrate for vertical rod 40, the flexure strip 212 of tool one V-type in this vertical rod 40, flexure strip 212 1 sides have a positioning bead 213, positioning bead 213 passes the hole 214 of vertical rod 40 and the hole 211 of uprise 21, and with in the vertical rod 40 location what uprises 21, slightly cave in and be provided with several grooves 22 symmetric arrays in regular turn in this surface, joint 20 top, and both sides respectively have a perforation 23, this perforation 23 is enough to make 41 ends of pole to be provided with diplopore 411 can to penetrate one and stick in 412, inserting column 412 can embed the transverse groove 241 of L type groove 24 bottoms, can rabbet a top cover 30 on this joint 20, face is provided with several raised lines 31 within the top cover 30, the groove 22 of raised line 31 and joint 20 is relative and can be chimeric, these top cover 30 relative what L type grooves 24 places are provided with a protruding upright bar 32, this protruding upright bar 32 can embed in the straight groove 242 of L type groove 24, the surface is provided with a jack 25 outside what joint 20 corners, side surface is established a flexure strip 26 (as Fig. 8 within joint 20 corners, shown in 9), flexure strip 26 ends convex with a fixture block 261, and top cover 30 places of what fixture block 261 are provided with a locating hole 34 relatively, this fixture block 261 can snap in the locating hole 34, and these top cover 30 relative what jacks 25 places are provided with a card body 33, and this card body 33 can insert in the jack 25;

Make up by said structure, the structure of a kind of play yard joint of the utility model, as Fig. 5,6,7, shown in 8, during combination pole 41, in system's perforation 23 with 41 what joints 20 of pole earlier, go into inserting column 412 in the diplopore 411 of what pole 41, inserting column 412 is slided to transverse groove 241 by L type groove 24 straight grooves 242 of joint 20, lay equal stress on to be covered with and state another pole 41 of action dress and go in the what joint 20, and the assembling of vertical rod 40 only needs vertical rod 40 is gone in the what uprise 21, snaps in the what hole 211 with positioning bead 213, raised line 31 with top cover 30 embeds in the groove 22 of what joint 20 again, protruding upright bar 32 embeds in the straight groove 242 of L type groove 24, with sealing L type groove 24, moves on the resistance shelves inserting column 412, the lamellar body 33 of described top cover 30 inserts in the jack 25 of what joint 20, the locating hole 34 of this top cover 30 embeds for the elasticity fixture block 261 of joint 20, assemble top cover 30 to finish, and the location articulates pole 41, pole 41 can be done the action of horizontal development or upright folding, firmly connects in the what joint 20 and does not get loose;

If will dismantle pole 41 and vertical rod 40, as long as earlier fixture block 261 is pushed the locating hole 34 of shrinking back and breaking away from top cover 30 into interior to point, again for taking out top cover 30, top cover 30 is separated with joint 20, then the protruding upright bar 32 of top cover 30 no longer seals L type groove 24, the inserting column 412 of pole 41 can be skidded off along L type groove 24, again the diplopore 411 of inserting column 412 from pole 41 taken out, this vertical rod 40 can be through pushing the hole 211 that positioning bead 213 breaks away from joint 20, make joint 20 break away from poles 41 and vertical rod 40 and can take out, finish the action of dismounting;

The design of described L type groove 24 has ingenious part, in the time of in the inserting column 412 of pole 41 is gone into what L type groove 24 transverse grooves 241, by the restricted what pole 41 of what inserting column 412 active forces upper and lower to; Therefore in all spacing what transverse groove 241 of active force of most application of force what inserting column 412; So the protruding upright bar 32 of position what straight groove 242 can be easily with in the inserting column 412 sealing what transverse grooves 241, even pole 41 is done horizontal development, upright folding, in the still spacing what transverse groove 241 of the inserting column 412 of pole 41;

And these joint 20 surfaces have several grooves 22 to be embedded for top cover 30 raised lines 31, and fixture block that joint 20 inside lock places are flexible 26 and the locating hole of top cover 30 34 fix, and joint 20 outer corners have a jack 25 to snap in for the card body 33 of top cover 30; Therefore,, no matter vertically horizontal top cover 30 is all firmly in conjunction with on the what joint 20;

The utility model assembling or dismounting all need not any instrument and can finish, and in a single day assembling finishes, and be very firm again, do not have the filter that gets loose.

Again, as shown in figure 10, be another embodiment of utility model, main system changes the composition surface of joint 50 into even surface, respectively be provided with jack 55 in bottom, composition surface, joint 50 both sides, top cover 60 each tool one card body 61 of relative what jack 55, card body 61 can snap in this jack 55, and the corner outer surface of what joint 50 is provided with a hole 57, and these top cover 60 corner inwalls are provided with a projection 65, and projection 65 can be gone in the hole 57, the L type groove of all the other relevant preceding embodiment joints, perforation, the protruding upright bar of flexure strip and top cover, locating hole, embodiment is identical all therewith, can reach above-mentioned combination and firm function, and does not need instrument to assemble, the dismounting joint.
