Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b): referring to fig. 1-5, a grid plate fastener includes a clip 1 and a connecting bolt 2, the clip 1 includes a connecting portion 101 and three clamping jaws 102, in this embodiment, the number of the clamping jaws 102 is three, the connecting portion 101 is rectangular, a central hole 103 is formed in the connecting portion 101 in a penetrating manner, the three clamping jaws 102 are respectively disposed on three sides of the connecting portion 101, the connecting portion 101 and the three clamping jaws 102 are integrally formed, the connecting bolt 2 penetrates through the central hole 103, the connecting bolt 2 is cylindrical and has an internal thread formed on an inner circumferential wall thereof, an annular groove 201 adapted to the central hole 103 is formed on an outer circumferential wall of the connecting bolt 2 along a circumferential direction of the connecting bolt 2, upper and lower outer diameters of the annular groove 201 are larger than an inner diameter of the central hole 103, the connecting bolt 2 is prevented from falling off, an elastic washer 202 is further sleeved on an outer portion of the annular groove 201, and the washer 202 is made of a silica gel material.

Through-hole 104 has been seted up in running through on the clamping jaw 102, be equipped with in the through-hole 104 and to the conflict portion 105 that turns over an outward, conflict portion 105 and clamping jaw 102 integrated into one piece, after clip 1 and connecting bolt 2 assemble on grid plate 3, the accessible turns over an outward conflict portion 105, makes conflict portion 105 and the laminating of the lateral wall of grid plate 3 to avoid grid plate 3 activity, help strengthening grid plate 3's stability.

The top surface of the clip 1 is attached to form a protective cover 5, the central position of the bottom surface of the protective cover 5 is integrally formed to form a sleeve 501, the outer side wall of the sleeve 501 is closely attached to the inner side wall of the clamping jaw 102, namely, the sleeve 501 is plugged into the clip 1 by applying vertical downward pressure. Four notches 203 are evenly seted up along connecting bolt 2's circumference on connecting bolt 2's top surface, and the effect is convenient for the staff utilizes instrument swivelling joint bolt 2 with mounting tool adaptation to breach 203.

In addition, in this embodiment, since the outer diameters of the upper and lower edges of the annular groove 201 are larger than the inner diameter of the central hole 103, the connecting bolt 2 cannot be directly inserted into the central hole 103, and therefore, the clip 1 and the connecting bolt 2 are assembled in advance through an injection molding process, and then the elastic washer 202 is sleeved outside the annular groove 201, thereby completing the factory setting.
