Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 4.

The utility model provides a fastener for outdoor solar photovoltaic board mounting bracket, including fastener body 1, fastener body 1 includes interior screw 3 and outer screw 2, be provided with the well cavity 9 that supplies interior screw 3 to inlay to establish on the outer screw 2, be equipped with on the outer peripheral face of outer screw 2 head end along radial extension's flange, be equipped with screw thread 6 on the outer peripheral face of outer screw 2, the inner peripheral surface of external screw thread 6 is equipped with stopper 7 that the symmetry was placed, stopper 7 is arranged in on well cavity 9 lateral wall, the terminal surface of interior screw 3 head end is equipped with cross recess 4, be equipped with the cross rotary rod 5 with cross recess 4 adaptation in the

cross recess

4, 3 tail end outer peripheral faces of interior screw are equipped with the rotatory T type groove 8 of stopper 7 cooperation and T type groove 8 is the symmetry and places, T type groove 8 includes sliding groove 13 and rotation recess 12, the both ends face of rotation recess 12 all is equipped with snubber block 11, snubber block 11 adopts rubber.

The fastener body 1 comprises an inner screw 3 and an outer screw 2, and the outer screw 2 is used for fixing two accessories. When two accessories are required to be fixed, firstly, a sliding groove 13 in a T-shaped groove 8 on the peripheral side of the tail end of an inner screw 3 is aligned with a limiting block 7 welded on the side wall of a hollow cavity 9, then the inner screw 3 slowly slides downwards, at the moment, the limiting block 7 slides in the sliding groove 13, when the limiting block 7 slides to a rotating groove 12, the limiting block 7 is in interference connection with the side wall of the rotating groove 12, then according to the rotating direction of a thread 6 arranged on the peripheral side of an outer screw 2, the inner screw 3 is selected to rotate clockwise or anticlockwise, so that the limiting block 7 slides along the rotating groove 12 until the limiting block 7 is in interference with the side wall of the rotating groove 12, in order to prevent the limiting block 7 from being in extrusion abrasion on the rotating groove 12 caused by the instant contact with the side wall of the rotating groove 12, a damping block 11 is arranged between the extrusion surfaces of the limiting block 7 and the rotating groove 12, in case stopper 7 contradicts with rotating 12 tip on the recess, the cross recess 4 and the cooperation of cross rotary rod 5 of the 6 head ends of internal thread rotate this moment, and cross rotary rod 5 is more laborsaving at the rotation in-process to cross recess 4 and cross dwang can be dismantled and conveniently carry. When the outer screw 2 is screwed down, the cross rotating rod rotates reversely to enable the limiting block 7 to be separated from the rotating groove 12 to reach the joint of the rotating groove 12 and the sliding groove 13, then the inner screw 3 is pulled out manually, and the outer screw 2 cannot be screwed out of the screw hole due to the absence of the inner screw 3, so that the anti-theft purpose is achieved.

The limiting block 7 is a cube, the limiting block 7 is arranged in the middle of the hollow cavity 9, and the limiting block 7 is connected with the side wall of the hollow cavity 9 in a welding mode.

In order to ensure that the limiting block 7 is easy to fix and slide, the limiting block 7 of the cube is selected, the limiting block 7 is placed in the middle of the hollow cavity 9, stress points are placed in the middle and are arranged at stress points at two ends, the stress points are too concentrated or dispersed, the structural strength of the internal screw rod and the stability in the rotating process are affected, and the limiting block 7 is prevented from falling off easily under stress and is connected in a welded mode.

The sliding groove 13 is arranged along the axis position of the inner screw 3, the rotating groove 12 is arranged along the periphery of the inner screw 3, one end of the sliding groove 13, far away from the rotating groove 12, extends outwards to the tail end face of the inner screw 3, and the tail end of the inner screw 3 is provided with a fine adjustment block 10.

The tail end of screw 3 including fine tuning block 10 sets up, even appear slightly rocking when interior screw 3 arranges cavity 9 in and also can not lead to interior screw 3 to be difficult for placing in cavity 9, when interior screw 3 arranged cavity 9 in during the lapse, stopper 7 can be smooth and fast with slip recess 13 alignment, so slip recess 13 sets up along the axis position of interior screw 3, can not appear stopper 7 and other lateral walls of rotation recess 12 in order to rotate the messenger simultaneously and take place to contradict, so it is perpendicular with slip recess 13 to rotate recess 12.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
