Abstract

The utility model discloses a simple connecting structure of a frame. The structure comprises a U-shaped fastener fitted and sleeved on a vertical rod, wherein two inner buckle claws extend outward up and down at the left and right side of the fastener to form a U-shaped hole in which a transverse rod passes through; the bottom of the U-shaped hole is semi-circular, and the diameter of the U-shaped hole is equal to that of the transverse rod. The structure further comprises a locking piece locked with the inner buckle claws of the fastener, wherein the locking piece is designed as a concave groove, two side walls of the locking piece are gradually widened from the upper end to the lower end, and the inner buckle claws of the fastener fasten the inner side of the side walls of the locking piece. The structure disclosed by the utility model is applied, so that the frame is more quick and convenient to install and detach and more steady and safer in structure.

Fig. 2 is the utility model fastener structural representation;

Fig. 3 is the utility model assembly structure schematic diagram.

Annotate: button pawl in 1-fastener, 1-1-, 2-fastener, 2-1-sidewall, 1 '-montant, 2 '-cross bar.

Embodiment

Now in conjunction with Figure of description, describe the mode of execution of this patent in detail.

As Fig. 1-3, a kind of Simple connecting structure of shelf, comprise that laminating is sleeved on the U-shaped fastener 1 on montant 1 ', described fastener 1 left and right sides respectively stretches out up and down the U-shaped hole that in two, button pawl 1-1 formation is passed for cross bar 2 ' is set, bottom, described U-shaped hole is semicircle, its diameter is identical with cross bar 2 ' diameter, also comprise one with the fastener 2 of the interior button pawl of fastener 1 1-1 clamping, described fastener 2 designs for Baltimore groove, described fastener 2 2-1Cong lower ends, two side are widened gradually to upper end, the interior button pawl of described fastener 1 1-1 fastening fastener 2 sidewall 2-1 inboards.

During use, first determine the height of wish fixed installation cross bar 2 ', U-shaped fastener 1 is sleeved on montant 1 ' corresponding height, then cross bar 2 ' one end is passed in fastener two U-shaped holes that Shang Xia 1, interior button pawl 1-1 forms, finally, from the lower end of fastener 2, fastener 2 sidewall 2-1 clampings outwardly enter in interior button pawl 1-1, fastener 2 backs prop up spreader, with instrument, knock fastener 2 upper ends downwards until fastener 2 can not move down, the interior button pawl of fastener 1 1-1 fastening fastener 2 sidewall 2-1 inboards, namely show cross bar 2 ' fixedly secured on montant 1 '.

The utility model is by the fastener 1 and the sidewall 2-1 groove type fastener 2 wide at the top and narrow at the bottom that are provided with interior button pawl 1-1, makes the montant 1 ' of shelf and cross bar 2 ' overlap joint, dismounting more efficient and convenient, and structure is more firm, safety.

The foregoing is only preferred embodiment of the present utility model, all impartial conversion and modifications of doing according to the utility model claim, all belong to the covering scope of the utility model patent.
