Description

Technical Field

[0001] The utility model relates to the technical field of anchor nails, in particular to an anchor nail for an exterior wall insulation board. Background Art

[0002] Anchor nails are a kind of fasteners connecting the wall and the insulation board. They are composed of galvanized screws, nylon expansion tubes and fixed discs. They are resistant to aging, temperature changes, corrosion, cold and heat, high bearing capacity, high pressure bearing, and good tensile properties. They are not easy to deform after loading, moisture-proof, vibration-slowing, noise absorption, and good insulation. They are easy to install by hammering, and no special installation tools are required.

[0003] However, when the existing external wall insulation board anchor nails are used, the external wall insulation board is usually fixed to the external wall by the anchor nails. A multi-layer structure is also arranged outside the insulation board. The anchor nails only use the barbed blocks to bite the external wall insulation board and the inside of the external wall, which will make their bite insufficient. The anchor nails on the external wall insulation board will become loose, and a gap will be generated between the external wall insulation board and the external wall, which will have a certain impact on the performance of the external wall insulation board. Therefore, an external wall insulation board anchor nail is provided. Utility Model Content

[0004] The main purpose of the utility model is to provide an anchor nail for an exterior wall insulation board. The utility model solves the problem that the bite force between the existing anchor nails for exterior wall insulation boards and the exterior wall cannot be enhanced during use, and the firmness between the exterior wall insulation board and the exterior wall is poor, by arranging a fixing rod, a protrusion, a fixing block, a cone block, a cavity, a through hole, a connecting block and a screw rod.

[0005] The technical solution adopted by the utility model to solve its technical problems is an external wall insulation board anchor nail, including a fixed disc, a connecting block and a screw rod, a nylon expansion tube entering the interior of the external wall insulation board is arranged on one side of the fixed disc, a connecting head driving the screw rod to rotate is welded on one side of the screw rod, a cross groove is provided on the inner side of the connecting head, a cavity for placing the fixing rod is provided inside the screw rod, a through hole for placing the protrusion is provided on the surface of the screw rod, a fixing block is welded inside the cavity, and a cone block connected to the fixing block is welded on one side of the fixing rod.

[0006] By adopting the above technical scheme, when the external wall insulation board is to be fixed, the nylon expansion tube is first nailed into the internal part of the external wall insulation board so that one end of the nylon expansion tube enters the internal part of the wall, and then the fixed disc outside the nylon expansion tube contacts the surface of the external wall insulation board, and then the screw rod is put into the nylon expansion tube, and the screw rod is driven to rotate through the connecting head, and then the screw rod enters the internal part of the nylon expansion tube, so that the nylon expansion tube expands and the nylon expansion tube is stuck in the wall, and then the fixing rod is put into the cavity inside the screw rod, and then the fixing rod is pushed to move, and then the fixing rod contacts the surface of the connecting block, and then the connecting block drives the protrusion to move outward through the through hole on the surface of the screw rod, and the cone block on the fixing rod enters the fixing block inside the cavity, so that the fixing rod is fixed inside the cavity, and then the protrusion passes through the nylon expansion tube into the external wall, so that the bite force between the anchor nail and the external wall insulation board and the external wall is enhanced, thereby improving the firmness between the external wall insulation board and the external wall.

[0007] Specifically, a reinforcement layer for improving the strength of the nylon expansion tube is arranged on the outer side of the nylon expansion tube.

[0008] By adopting the above technical solution, a reinforcement layer is arranged on the outside of the nylon expansion tube, thereby improving the strength of the nylon expansion tube.

[0009] Specifically, the nylon expansion tube is integrally formed with a barb block on the outside for fixing the nylon expansion tube in the exterior wall insulation board.

[0010] By adopting the above technical solution, when the nylon expansion tube is placed in the exterior wall insulation board, the barb blocks outside the nylon expansion tube are stuck in the exterior wall insulation board, so that the nylon expansion tube is fixed in the exterior wall insulation board and the nylon expansion tube is prevented from moving out of the exterior wall insulation board.

[0011] Specifically, protrusions for increasing the friction force between the fixing rod and the connecting block are welded on the outer side of the connecting block.

[0012] By adopting the above technical solution, when the fixing rod drives the connecting block to move, the fixing rod contacts the protrusions on the surface of the connecting block, thereby increasing the friction force of the fixing rod on the connecting block and facilitating the fixing rod to drive the connecting block to move.

[0013] Specifically, the reinforcement layer is made of a wire mesh sleeve.

[0014] By adopting the above technical solution, the reinforcing layer made of the wire mesh sleeve is fixed on the nylon expansion tube, thereby improving the strength of the nylon expansion tube.

[0015] Beneficial effects of the utility model:

[0016] The utility model discloses an anchor nail for an external wall insulation board. When the external wall insulation board is to be fixed, the nylon expansion tube is first nailed into the internal part of the external wall insulation board so that one end of the nylon expansion tube enters the internal part of the wall. Then, the fixing disc outside the nylon expansion tube contacts the surface of the external wall insulation board. Then, the screw rod is put into the nylon expansion tube, and the screw rod is driven to rotate through the connecting head. Then, the screw rod enters the internal part of the nylon expansion tube so that the nylon expansion tube expands and is stuck in the wall. Then, the fixing rod is put into the cavity inside the screw rod. Then, the fixing rod is pushed to move. Then, the fixing rod contacts the surface of the connecting block. Then, the connecting block drives the protrusion to move outward through the through hole on the screw rod surface. The cone block on the fixing rod enters the fixing block inside the cavity, so that the fixing rod is fixed inside the cavity. Then, the protrusion passes through the nylon expansion tube and enters the external wall, so that the bite force between the anchor nail and the external wall insulation board and the external wall is enhanced, thereby improving the firmness between the external wall insulation board and the external wall.
