Description

Technical Field

[0001] This utility model relates to the field of anchor nail technology, and in particular to an anchor nail for external wall insulation boards. Background Technology

[0002] Insulation board anchoring nails are specialized engineering plastic expansion nails used to fix insulation boards to walls. They are widely used in building exterior wall insulation projects. One type of exterior wall insulation board anchoring nail, with publication number CN222632550U, involves first inserting a nylon expansion tube into the insulation board, ensuring one end of the tube is inside the wall. Then, the fixing disc on the outside of the tube contacts the surface of the insulation board. Next, a screw rod is inserted into the tube, and the connecting head rotates the screw rod. The screw rod then... The nylon expansion tube is inserted into the wall, causing it to expand and become locked inside. Then, the fixing rod is inserted into the cavity inside the screw rod, and the fixing rod is pushed to move. The fixing rod then contacts the surface of the connecting block, and the connecting block drives the protrusion to move outward through the through hole on the surface of the screw rod. The cone on the fixing rod enters the fixing block inside the cavity, fixing the fixing rod inside the cavity. Then, the protrusion passes through the nylon expansion tube into the outer wall, which enhances the interlocking force between the anchor nail and the outer wall insulation board and the outer wall, thereby improving the firmness between the outer wall insulation board and the outer wall.

[0003] However, if the nylon expansion tube is not securely fixed after being placed into the wall, it may shift during subsequent operations. For example, when the installer performs other operations (such as installing screw rods), the nylon expansion tube may be accidentally touched, causing its position to shift and thus affecting the final installation effect of the anchor nail.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figure 1 and Figure 3 As shown, an anchor nail for an external wall insulation board includes an expansion sleeve 1 for fixing to the wall. One end of the expansion sleeve 1 is open and the other end is closed, with the closed end of the expansion sleeve 1 embedded in the wall. An internal threaded ring 2 is inserted into the open end of the expansion sleeve 1, and several through grooves 10 are provided on the inner wall of the expansion sleeve 1 near the closed end. A socket 14 is fixedly installed on the inner wall of the expansion sleeve 1 near the open end. Several columnar protrusions extending along the rotation axis of the expansion sleeve 1 on one side of the socket 14 penetrate the internal threaded ring 2. An external threaded ring 3 is threadedly connected to the open end of the expansion sleeve 1 for abutting against one end of the internal threaded ring 2, facilitating the installation and removal of the internal threaded ring 2. Specifically, the external threaded ring 3 can be rotated off, and then the internal threaded ring 2 can be directly slid out along the columnar protrusions on the surface of the socket 14. The several through grooves 10 are divided into several groups in equal numbers, and the several groups of through grooves 10 are distributed in a ring array about the rotation axis of the expansion sleeve 1. A damping mechanism for the inner wall of the wall is provided at any position of any through groove 10 in the expansion sleeve 1. The abutment blocks 9 are integrally formed in each group of through grooves 10, and the abutment blocks 9 in each group of through grooves 10 are arranged along the central axis of the expansion sleeve 1. The closed end of the expansion sleeve 1 is provided with an annular groove 11. One end of the integrally formed abutment blocks 9 is fitted into the annular groove 11, and the other end of the integrally formed abutment blocks 9 is slidably installed with a spring piece 12 fixed in the expansion sleeve 1. With the thrust of the spring piece 12 and the assistance of the annular groove 11, the abutment blocks 9 are stored in the expansion sleeve 1 under normal conditions, without affecting the insertion of the expansion sleeve 1 into the hole drilled in the wall. The internal thread ring 2 is threadedly connected to a bolt 7 on the side near the open end of the expansion sleeve 1. The head of the bolt 7 is rotatably connected to an annular fixing piece 8. After the expansion sleeve 1 is completely fixed in the wall, the bolt 7 is screwed on and passes through the external wall insulation board. The fixing piece 8 on the surface of the bolt 7 is used to press the external wall insulation board to fix the position of the external wall insulation board.

[0023] like Figure 2 and Figure 4 A stud 4 is threadedly connected to one end of the inner wall of the internal threaded ring 2 near the contact block 9. The side of the stud 4 is used for sliding connection with the surfaces of several integrally formed contact blocks 9. A countersunk groove 6 is provided at one end of the stud 4, and an annular retaining groove 5 is provided on the surface of the stud 4 near the end of the internal threaded ring 2. A retaining block 13 is hinged inside the expansion sleeve 1 near the internal threaded ring 2, and engages with the inner wall of the retaining groove 5. The retaining block 13 is hinged inside the expansion sleeve 1 by a spring hinge and is set perpendicular to the rotation axis of the expansion sleeve 1. The retaining block 13 swings toward the closed end of the expansion sleeve 1. By inserting a hex wrench into the countersunk groove 6 and driving the stud 4 to rotate, the threaded connection between the stud 4 and the internal threaded ring 2 allows the stud 4 to be continuously inserted into the expansion sleeve 1. The contact between the surface of the stud 4 and the surface of the abutment block 9 pushes the abutment block 9 to overcome the thrust of the spring piece 12 and pass through the through groove 10 and tightly abut against the inner wall of the hole drilled on the wall, thus completely fixing the position of the expansion sleeve 1. The stud 4 moves until several locking blocks 13 are locked into the locking grooves 5 on the surface of the stud 4, thus preventing the stud 4 from rotating and dislodging from the expansion sleeve 1 due to vibration.

[0024] Working principle: Drill holes in the wall and insert the expansion sleeve 1 into the holes. Insert a hex wrench into the countersunk groove 6 and drive the stud 4 to rotate. The stud 4 is continuously inserted into the expansion sleeve 1 through the threaded connection between the stud 4 and the internal threaded ring 2. During the movement of the stud 4, it pushes the abutment block 9 to overcome the thrust of the spring piece 12 and pass through the through groove 10 and tightly abut against the inner wall of the drilled hole in the wall, so as to completely fix the position of the expansion sleeve 1. Drill holes in the external wall insulation board according to the installation position of the expansion sleeve 1, insert the bolt 7, and install the bolt 7 through the threaded connection between the bolt 7 and the internal threaded ring 2. The fixing piece 8 on the surface of the bolt 7 is used to press the external wall insulation board.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
