a quick rear box fixing structure comprises a ceramic body, a rear box and a fixing unit for fixing the rear box on the ceramic body, wherein the fixing unit comprises a screw, a petal locking joint and an expansion nut, the petal locking joint comprises a bowl-shaped body, the bottom of the bowl-shaped body is provided with a screw through hole for the screw to pass through, the wall part is composed of a plurality of elastic buckles, the elastic buckles are arranged in a ring shape at intervals, and the outer side of at least one elastic buckle is also provided with a clamping convex edge; the expansion nut is inserted in the ceramic body, the petal lock joint is located in a base of the rear box, the screw penetrates through the bottom of the petal lock joint to enter the expansion nut, a fixing unit mounting hole is formed in the base of the rear box, and the petal lock joint can deform and can deform to enter the fixing unit mounting hole through the fixing unit mounting hole or at least one part of the petal lock joint.

In a preferred embodiment: the number of the elastic buckles is 2-10.

In a preferred embodiment: the clamping convex ribs are arranged at intervals of one elastic buckle.

In a preferred embodiment: the upper side and the lower side of each clamping convex ridge are respectively provided with an upper inclined plane and a lower inclined plane.

In a preferred embodiment: each elastic buckle is obliquely arranged, namely, the elastic buckle is gradually far away from the axis direction of the petal lock joint from bottom to top.

In a preferred embodiment: the petal lock joint further comprises a first gasket, and the first gasket is positioned on the upper surface of the bottom of the petal lock joint.

In a preferred embodiment: the expansion nut further comprises a second gasket, and the second gasket is positioned between the bottom end of the bowl-shaped lock joint and the top end of the expansion nut.

Compared with the background technology, the technical scheme has the following advantages:

the utility model discloses fixed unit includes screw, petal lock joint and inflation nut, the petal lock joint wall portion constitute for a plurality of elasticity buckles, the interval arrangement is cyclic annular each other, like this, the petal lock joint can warp through fixed unit mounting hole or at least some that the petal lock joint can warp and get into the fixed unit mounting hole. Therefore, after the first installation is completed, a screwdriver is not needed to be used during each installation or disassembly, and the rear box can be directly sleeved on the fixing unit or pulled out from the ceramic body by means of deformation of the petal lock joint.

Detailed Description

Referring to fig. 1 to 4, a quick rear box fixing structure includes a ceramic body 100, a rear box base 200, and a fixing unit 300.

The fixing unit 300 includes a screw 310, a first washer 320, a petal lock joint 330, a second washer 340, and an expansion nut 350. The petal lock joint 330 comprises a bowl-shaped body 331, the bottom of the bowl-shaped body 331 is provided with a screw through hole for a screw to pass through, the wall part is composed of a plurality of elastic buckles 332, the elastic buckles are arc-shaped and are arranged in a ring shape at intervals, and each elastic buckle is obliquely arranged, namely, the elastic buckle is gradually far away from the axis direction of the petal lock joint 330 from bottom to top. Clamping ribs 333 are further arranged on the outer sides of some elastic buckles close to the upper ends, and the clamping ribs 333 are preferably arranged at intervals of one elastic buckle. The upper and lower sides of each of the catching ribs 333 are respectively provided with an upper slope 334 and a lower slope 335 to facilitate passage of the fixing unit mounting holes 210 of the rear box base when being mounted.

The first spacer 320 is located on the bottom upper surface of the body 331 of the petal lock fitting 330 and the second spacer 340 is located between the bottom end of the bowl lock fitting 330 and the top end of the expansion nut.

Referring to fig. 5, the left and right sides of the rear case base are respectively provided with a fixing unit mounting hole 210.

The utility model discloses an installation as follows: referring to fig. 3 to 5, the expansion nut 350 is inserted into the fixing hole of the ceramic body 100, the second spacer 340 is placed on the top of the expansion nut, the first spacer 320 is placed in the petal lock joint 330, the first spacer 320 and the petal lock joint 330 are placed on the second spacer 340, and the screw 310 sequentially passes through the first spacer 320, the bottom of the petal lock joint 330, the second spacer 340 and the expansion nut, so that the whole fixing unit is fixed on the ceramic body 100. Finally, the fixing unit mounting hole of the rear box base is sleeved in alignment with the petal lock joint 330, and in the process of sleeving, the elastic buckle deforms inwards until the clamping convex edge 333 is exposed out of the upper surface of the rear box base, and the rear box base is fixed by expanding the clamping convex edge 333 again.

When the rear box base is disassembled, the whole rear box base can be pulled up by force directly without disassembling screws, and the whole rear box base can be pulled out by the deformation of the elastic buckles of the petal lock joints 330.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
