Description
Technical Field
[0001] This utility model belongs to the field of connector technology, specifically relating to a connector for installing building exterior wall insulation panels that is easy to disassemble. Background Technology
[0002] The fixing nails used for installing building exterior wall insulation panels consist of two parts. After the initial installation of the exterior wall insulation panels is completed, the construction workers will pre-drill mating holes at the joints of the insulation panels for installing the fixing nails. Next, the construction workers will insert the shank of the fixing nail into the mating hole, and finally insert an inner nail into the shank. The inner nail opens the expansion end of the shank, securing the entire fixing nail in the mating hole. In this way, one end of the fixing nail will also reinforce the exterior wall insulation panel to the wall surface.
[0003] However, the current expansion structure is limited by the overall length of the fixing nail during actual installation, thus restricting the expansion area. This results in poor friction during expansion in areas where the inner walls of the mating holes are not smooth, making it difficult for the fixing nail to be securely fixed in the holes. Consequently, the actual effective number of fixations does not meet building code requirements, thereby reducing the pass rate. Utility Model Content
[0004] The purpose of this invention is to provide a building exterior wall insulation board installation connector that is easy to disassemble. This addresses the limitation imposed by the overall length of the fixing nails in current expansion structures, which restricts the expansion area. Consequently, in areas where the inner walls of the mating holes are not smooth, the expansion friction effect is reduced, making it difficult for the fixing nails to be securely fixed in the holes. This results in the actual effective fixing quantity failing to meet building code requirements, thus lowering the pass rate.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a building exterior wall insulation board installation connector that is easy to disassemble, including a nail rod, an end cap integrally connected to the end of the nail rod, and an inner rod movably inserted into the inside of the nail rod; A positioning ring is integrally provided on the inner wall of the inner rod, and a ring groove is formed on the outer wall of the inner rod near the end. The inner rod forms a positioning docking structure with the nail rod through the snap-fit of the ring groove and the positioning ring. A pressing rod is inserted into the inside of the inner rod, and the pressing rod is located on the bottom outer wall of the inner rod and is movably docked with one side of the six movable plates.
[0006] As a building exterior wall insulation board installation connector that is easy to disassemble according to this utility model, preferably, the four corners on both sides of the movable plate are arc-shaped structures, and the bottom of the extrusion rod is a semi-circular structure.
[0007] As a building exterior wall insulation board installation connector that is easy to disassemble according to this utility model, preferably, six rectangular grooves are evenly spaced through the outer wall of the nail rod near the top, and six guide grooves are evenly spaced through the inner wall of the nail rod. The bottom opening of each of the guide grooves is connected to the top of each of the rectangular grooves; One end of each movable plate can be adjusted and extended outward by passing through the corresponding rectangular groove, and each movable plate is positioned and installed inside the nail rod along the trajectory of the corresponding guide groove.
[0008] As a building exterior wall insulation board installation connector that is easy to disassemble according to the present utility model, preferably, the inner rod has an inner cavity, and the top opening of the inner cavity extends to the outer wall of the top of the inner rod, and the extrusion rod is inserted into the inner rod through the inner cavity.
[0009] Compared with the prior art, the beneficial effects of this utility model are: After the initial installation of the exterior wall insulation boards, drive nails into the joints, then insert the inner rods. During installation, adjust the six movable plates at the ends of the inner rods outwards appropriately, allowing them to follow the corresponding guide grooves into the nails along with the inner rod. Once the annular groove on the inner rod aligns with the positioning ring on the end, one end of each of the six movable plates will be aligned with the corresponding rectangular groove opening. Then, hammer the pressing rod into the inner cavity. The pressing rod will push the six movable plates outwards, causing the other side of each movable plate to pass through the rectangular groove and press against the inner wall of the installation hole. This ensures the nails are more securely installed in the installation holes of the exterior wall insulation boards, thereby improving the success rate of nail installation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-5 The present invention provides the following technical solution: a building exterior wall insulation board installation connector that is easy to disassemble, including a nail rod 1, an end head 2 integrally connected to the end of the nail rod 1, and an inner rod 3 movably inserted into the nail rod 1; A positioning ring 4 is integrally formed on the inner wall of the inner rod 3. A ring groove 5 is formed on the outer wall of the inner rod 3 near the end. The inner rod 3 forms a positioning docking structure with the nail rod 1 through the engagement of the ring groove 5 and the positioning ring 4. The positioning ring 4 is made of fluororubber. When the positioning ring 4 docks with the ring groove 5, the positioning ring 4 will deform due to the compression of the inner rod 3. When the ring groove 5 moves to the positioning ring 4, the positioning ring 4 will promptly reset and lock into the ring groove 5. A pressing rod 7 is inserted into the inner rod 3. The pressing rod 7 is located on the bottom outer wall of the inner rod 3 and is movable and docked with one side of the six movable plates 6.
[0018] The top of the compression rod 7 has a threaded notch, which is then aligned with a bolt of the corresponding size during disassembly. The compression rod 7 is then pulled outwards by pulling the bolt, allowing it to be easily removed from the inner rod 3. This releases the compression of the six movable plates 6 from the compression of the compression rod 7, thus relieving the pressure between them and the inner wall of the mating hole. This allows the nail rod 1 to be easily removed from the mating hole, facilitating subsequent disassembly operations.
[0019] Preferably, the four corners on both sides of the movable plate 6 are arc-shaped, and the bottom of the extrusion rod 7 is semi-circular.
[0020] In practical use, the arc-shaped end corner of the movable plate 6 reduces obstruction between it and the movable docking end of the pressing rod 7 and the rectangular groove 11, thus allowing the semi-circular end of the pressing rod 7 to be easily inserted between the six movable plates 6. Additionally, the movable plate 6 can also smoothly slide in and out of the docking point of the rectangular groove 11. Preferably, six rectangular slots 11 are equally spaced through the outer wall of the nail rod 1 near the top, and six guide slots 12 are equally spaced through the inner wall of the nail rod 1; The bottom opening of each guide groove 12 is connected to the top of each rectangular groove 11; One end of each movable plate 6 can be moved through the corresponding rectangular groove 11 and extended outward. Each movable plate 6 is positioned and installed inside the nail rod 1 along the trajectory of the corresponding guide groove 12.
[0021] In actual use, after the movable plate 6 enters the nail rod 1 along the corresponding guide groove 12, the movable plate 6 will align with the opening of the corresponding rectangular groove 11 after docking, which facilitates the later extension of the movable plate 6 outward.
[0022] Preferably, the inner rod 3 has an inner cavity 31 inside, and the top opening of the inner cavity 31 extends to the outer wall of the top of the inner rod 3, and the extrusion rod 7 is inserted into the inner rod 3 through the inner cavity 31.
[0023] Working principle: Nail rods 1 are driven into the joints of the pre-installed exterior wall insulation boards, and then inner rods 3 are inserted into nail rods 1. During installation, the six movable plates 6 at the ends of the inner rods 3 are adjusted outwards appropriately so that the movable plates 6 can enter the nail rods 1 along the corresponding guide grooves 12 as the inner rods 3 are installed.
[0024] When the annular groove 5 on the inner rod 3 aligns with the positioning ring 4 on the end 2, one end of each of the six movable plates 6 will align with the opening of the corresponding rectangular groove 11. Then, the pressing rod 7 is hammered into the inner cavity 31. The pressing rod 7, entering the inner cavity 31, will press the six movable plates 6 outwards, causing the other side of each movable plate 6 to pass through the rectangular groove 11 and press against the inner wall of the installation hole. This allows the nail rod 1 to be more securely installed in the installation hole of the building's exterior wall insulation board, thereby improving the pass rate of the nail rod 1 after installation.
[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
