The present application claims priority under 35 U.S.C. 119(a-d) to CN 201820904503.5, filed Jun. 12, 2018.
The present invention relates to a device for fixing screws, hooks, etc. on a wall, which is disposed in a wall body made of materials of board, plaster tablet or the like.
The wall of a civil building in countries out of China is generally made of wood or gypsum board. If a hook or a screw is needed to be installed on the wall, it is usually necessary to embed a kind of fastener in the wall body, and the fastener is a wall anchor. While installing the wall anchor, firstly drilling mounting hole in the wall with the electric drill is required, then the wall anchor body is extended into the wall through the mounting hole, and the wall anchor body is in contact with the internal wall of the wall body. At the moment, push the mounting buckle forward along the rope belt into the mounting hole, fasten the mounting buckle to the wall, and screw the screw through the center hole of the mounting buckle. The front end of the screw is combined with the screw hole on the wall anchor body to fix the screw onto the wall body, it is used to install hooks or fasten some objects to the wall. Thus, it can be seen that special tools are required during the installation process, and certain installation skills are required, and non-professionals cannot complete the installation, which has the disadvantage of inconvenient use.
In order to overcome the disadvantages in the conventional art, an object of the present invention is to provide a new wall anchor that can be manually installed without prior drilling.
Accordingly, in order to achieve the objects mentioned above, technical solutions adopted by the present invention are as follows. A new wall anchor comprises:
a body, wherein the body comprises a bottom plate and two side plates which are connected with each other; wherein a screw hole is provided in the bottom plate; and
a tip section provided on a front end of the body;
wherein a tool palette is provided between the bottom plate and the tip end portion on the body; two side faces of the tool palette are respectively contacted with internal walls of the two side plates; a tooling hole is provided on the tool palette, wherein a central axis of the tooling hole, a longitudinal center line of the body and a longitudinal center line of the tip end portion are located on an identical straight line. An end of the body which is firstly contacted with the wall is defined as a front end. A predetermined mounting position of the wall is quickly positioned in by the positioning tip on the tip end section by a customer. After positioning, by combining a front end of a mounting tool such as a manual or electric screwdriver, with the tool hole on the tool board, the mounting tool is strongly rotated with force. The blades on the two side tips of the tip portion facilitate rapid drilling because the tool palette is located between the screw hole and the tip end section, and the tool palette is located between the screw hole and the tip end section, and behind the tip end section. The central axis of the tooling hole, the longitudinal center line of the body, the longitudinal center line of the tip end portion are located on the identical straight line. Rotating the mounting tool is capable of forcing the body to stably enter the wall without deviating from a center of the installation position. The fixing strap is provided on the internal wall of the body, and the fixing strap is mounted with the mounting buckle. After the body enters the wall body, one end of the body is suspended by gravity, so that the body is in contact with the internal wall of the wall, and at the moment, the buckle is pushed forward along fixing strap into the mounting hole drilled by the tip end section, fixes the mounting buckle to the wall, and screws a screw through a center hole of the mounting buckle, and the screw passes through the fixing strap located in the wall to connect the center hole on the body, in such a manner that the body is fixed on the wall. A hook and other objects may be fixed to the wall by the screw, just by breaking and removing the fixing strap on an external of the wall.
In order to fix the tool palette, two fixing blocks for fixing two sides of the tool palette are respectively provided on each of the two side plates.
In order to quickly locate and drill a mounting hole, the tip end portion comprises a positioning tip and two side tips provided on both sides of the positioning tip, two blades are respectively provided on the two side tips; front ends of the positioning tip protrude from front ends of the two side tips.
A strip hole is provided on the bottom plate; two circular holes are respectively provided on the two side plates.
The two side tips are respectively disposed at front ends of the two side plates and the side tips are integrally molded with the side plates; the positioning tips are located at a front end of the bottom plate.
The bottom plate is integrally molded with the two side plates, and the tip end portion is integrally molded with the body.
Beneficial effects of the present invention are as follows. A predetermined mounting position of the wall is quickly positioned in by the positioning tip on the tip end section by a customer. After positioning, by combining a front end of a mounting tool such as a manual or electric screwdriver, with the tool hole on the tool board, the mounting tool is strongly rotated with force. The blades on the two side tips of the tip portion facilitate rapid drilling because the tool palette is located between the screw hole and the tip end section, and the tool palette is located between the screw hole and the tip end section, and behind the tip end section. The central axis of the tooling hole, the longitudinal center line of the body, the longitudinal center line of the tip end portion are located on the identical straight line. Rotating the mounting tool is capable of forcing the body to stably enter the wall without deviating from a center of the installation position. The fixing strap is provided on the internal wall of the body, and the fixing strap is mounted with the mounting buckle. After the body enters the wall body, one end of the body is suspended by gravity, so that the body is in contact with the internal wall of the wall, and at the moment, the buckle is pushed forward along fixing strap into the mounting hole drilled by the tip end section, fixes the mounting buckle to the wall, and screws a screw through a center hole of the mounting buckle, and the screw 8 passes through the fixing strap located in the wall to connect the center hole on the body, in such a manner that the body is fixed on the wall.
In order to make the present invention to be better understood by the skills in the art, further descriptions of the present invention is illustrated combining with the accompanying drawing and the preferred embodiments of the present invention.
As shown in
