Embodiment

Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 6 and Figure 7, the utility model embodiment's connection set comprises pin thread 1, box 2, coupling shaft 3, loam cake 4.

As Fig. 1 and shown in Figure 6, the north glue spare that pin thread 1 is made up of two semi-enclosed first housings 12 and second housing 13, first housing 12 and second housing 13 interconnect along its bottom margin respectively and make integrative-structure, and first housing 12 and second housing 13 can be done predetermined angle along the bottom margin connecting line and rotate; Cavity 14 correspondence respectively is located on first housing 12 and second housing 13, and first housing 12 and second housing 13 are installed back cavity 14 and surrounded the semiclosed holding cavity 11 of formation; Breach 15 is semicircle breach, and it is corresponding being located on the sidewall of first housing 12 and second housing 13 respectively, and first housing 12 and second housing 13 are installed described breach 15 correspondences in back and surrounded the formation mounting hole; Described first housing 12 is provided with locating column 16, the second housings 13 and is provided with the positioning hole 17 that mates with locating column 16, is conducive to the location during installation, and the surface of contact between first housing 12 and second housing 13 is not breakked away.

As shown in Figures 2 and 3, box 2 also is to be cylindrical north glue spare, its inside is provided with cavity 21, described cavity 21 connects by passage 22 and outer wall, described box 2 outer walls are provided with fixing part 23, and particularly, described passage 22 is beeline channels that a cross section is rectangle, cavity 21 is to be that diameter and the center of circle are positioned at the circular cavity 21 on passage 22 medial axis with rectangular length, and described fixing part 23 is arranged on screw thread and/or the boss on the cylindrical sidewall; Described box 2 bottoms are provided with sealing cover 24, sealing cover 24 surrounds the described cavity 21 of formation with the inwall of box 2, because box 2 when mounted, more firm in order to make that box 2 is connected with furniture board, filling adhesive in the prefabricated fixed hole on furniture board, it is bonding with coupling shaft 3 that sealing cover 24 can avoid Bond to enter in the cavity 21, influences the rotation of coupling shaft 3; Form a slope 25 on the end face of described cavity 21 and passage 22 connecting ends, when locking block 32 rotates in cavity 21, the extruding force of the side of 25 pairs of locking blocks 32 of slope constantly increases, and is under the effect of extruding force that locking block 32 is fixing locked, avoids coupling shaft 3 to rotate.

As shown in Figure 4, coupling shaft 3 be circumferentially with slide block 31, first end of coupling shaft 3 is located in the mounting hole on the pin thread 1 and this slide block 31 is contained in and does predetermined angle in the described holding cavity 11 and rotate, second end of coupling shaft 3 is provided with the locking block 32 with passage 22 couplings, locking block 32 is contained in the described cavity 21 after passing described passage 22, particularly, locking block 32 be arranged on coupling shaft 3 second ends and with the smaller cuboid of above-mentioned rectangular cavity 21, locking block 32 passes passage 22 backs and rotation one angle under the drive of coupling shaft 3 like this, locking block 32 just is connected on the inwall of circular cavity 21, makes box 2 lockings.

As shown in Figure 5, described loam cake 4 covers on described holding cavity 11, vertical described loam cake 4 surfaces extend upward the wallboard 41 that forms with holding cavity 11 form fit, these wallboard 41 sidewalls and holding cavity 11 inwall interference fit after loam cake 4 covers with described holding cavity 11, and adopt loam cake 4 that the holding cavity 11 on the pin thread 1 is closed, not only pin thread is specious, smooth, and dust, foreign material can't accumulate in the holding cavity 11, avoid coupling shaft 3 stuck phenomenon to occur, the top of described wallboard 41 is provided with lead-in chamfered 42, and guiding loam cake 4 covers with holding cavity 11.

During assembling, as Fig. 8 and shown in Figure 9, at first with first housing 12 and second housing 13 along the bottom edge Unscrew, first end of coupling shaft 3 is located in the semicircle breach 15, then first housing 12 and second housing 13 are closed up, at this moment in the positioning hole 17 that the locating column on first housing 12 16 inserts on second housing 13, and slide block 31 is contained in the holding cavity 11 and can does predetermined angles and rotate, pin thread is fixed in the prefabricated fixed hole on the furniture board, and guarantee that second end of coupling shaft 3 stretches out the edge of plate this moment; Secondly, box is fixed in the prefabricated fixed hole on another piece furniture board; Be contained in the cavity 21 after then the locking block 32 on the coupling shaft 3 being passed passage 22, stirring slide block 31 this moment is connected on holding cavity 11 inwalls up to the struck side of slide block 31 around the axial direction rotation of coupling shaft 3, and then drive locking block 32 and cavity 21 in, rotate, box 2 is fastened on the locking block 32 at this moment; At last loam cake 4 and described holding cavity 11 are covered.

During dismounting, only need to open loam cake 4, stir coupling shaft 3 counterrotatings, and then drive locking block 32 rotations to the position of passage 22 form fit, this moment mobile furniture board, the locking block 32 that drives coupling shaft 3 withdraws from passage 22 to be separated with cavity 21, and then makes pin thread 1 separate with box 2, reaches need just can easily plate not assembled or disassemble by the situation of any special tool.

The above is embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some modifications, these are revised and also are considered as protection domain of the present utility model.
