A kind of Wedge Anchor that is convenient for installation comprises a bolt, a nut, a large washer, an elastic washer and an expansion sleeve, the expansion sleeve is provided with a through hole for the bolt to pass through, one end of the bolt far away from the nut is provided with a plurality of mounting grooves along the circumferential equidistance along the circumferential direction, a spring is arranged in the mounting groove, the other end of one end connected with the mounting groove relative to the spring is provided with a resisting block, the expansion sleeve is provided with the opening that can be stretched out by the contradicting block corresponding to the mounting groove, and the baffle that can block the contradicting block stretching out between the openings is arranged. The installation process is simple, convenient, and labor-saving.
The Wedge Anchor, also commonly known as expansion bolt, is generally composed of screw column, expansion head, expansion sleeve, nut, washer and gasket and other parts. The existing expansion head is generally a round table body, and the expansion sleeve is a straight sleeve with a plurality of straight seams at one end. Twist the nut or screw column, and the expansion head expands the expansion sleeve so that the Wedge Anchor expands and is fixed in the drill hole.
But the installation of the Wedge Anchor is more troublesome, because of the existence of the expansion head, the Wedge Anchor needs to be hammered into the borehole with a hammer first, and then tighten the nut to make the expansion head move to the expansion sleeve and enter the expansion sleeve to make it expand, so as to achieve fixation, and in this process need to tighten the nut forcefully, which is more laborious.
Aiming at the existing problems in the prior art, the utility model provides a kind of Wedge Anchor that is convenient for installation, and the installation process is simple, convenient, and labor-saving.
In order to achieve the above purpose, the utility model provides the following technical scheme: a Wedge Anchor that is convenient for installation comprises a bolt, a nut, a large washer, elastic washer and expansion sleeve, the expansion sleeve is provided with a through hole for the bolt to pass through, one end of the bolt far away from the nut is equidistant along the circumferential equidistance with a plurality of mounting grooves, a spring is arranged in the mounting groove, the other end of the spring connected with the mounting groove is provided with a countering block, the expansion sleeve is provided with an opening that can be stretched out by the contradicting block corresponding to the mounting groove, and a baffle that can block the contradicting block stretching out between the openings is arranged.
Adopt above-mentioned technical scheme, the contact block is positioned at the baffle below the baffle and is blocked by the baffle before use, the rotating bolt makes the contact block rotate from the baffle below to the opening during use, the contact block can stretch out from the opening at this moment, and contradicts the wall, thereby attaining the purpose of fixing, and the installation process is simple, convenient, and labor-saving. Further, the peripheral surface of the expansion sleeve is provided with a convex anti-skid block.
Adopting above-mentioned technical scheme, such arrangement can fix the expansion sleeve through the conflict between the anti-slide block and the wall so that it cannot rotate, so that the bolt can rotate, and the expansion sleeve can be avoided to rotate with the bolt so that the resisting block can not leave from the baffle below. Further, the surface of the anti-slide block is provided with uneven lines.
Adopting above-mentioned technical scheme, such a setting can enhance the roughness of the anti-slide block surface, thereby increasing the friction between the anti-slide block and the wall. Further, the anti-slip block is made of elastic material.
Adopting above-mentioned technical scheme, such arrangement can make the anti-slide block can be compressed on the wall, and give a certain force to the wall by being compressed, so that the anti-slide block is fixed with the wall, so that the effect of fixing the expansion sleeve is played.
