Description

Technical Field

[0001] This utility model relates to the field of external wall insulation technology, and in particular to an external wall insulation board connector. Background Technology

[0002] External wall insulation panels are a core component of building energy-saving projects. By attaching or fixing insulation panels to the exterior of building walls, building energy consumption can be effectively reduced and indoor thermal comfort improved. Connectors, as key connecting components between the insulation panels and the building's main structure, directly determine the safety and stability of the insulation system. Currently, insulation panel connectors suffer from poor compatibility; single-specification connectors cannot meet the installation requirements of insulation panels of different widths and lengths. Therefore, we propose an external wall insulation panel connector. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an external wall insulation board connector.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an external wall insulation board connector, including a base, two circular shafts extending to the back side are slidably mounted on the front side of the base, an mounting plate is fixedly connected to the outer wall of the base, a return spring is fixedly provided on the outer wall of the base, an adjustment component is provided inside the mounting plate, and the base is disc-shaped.

[0005] Preferably, the base has two circular grooves extending to the back side, and the two circular shafts are slidably connected in the two circular grooves respectively. The outer walls of the two circular shafts are fixed with threads near their ends.

[0006] Preferably, the back of the base has an inner groove corresponding to the position of the two circular grooves, and the ends of the two circular shafts are fixedly connected with caps, which are slidably engaged in the two inner grooves.

[0007] Preferably, four mounting plates are provided, and the four mounting plates are arranged in a cross shape.

[0008] Preferably, the adjustment assembly includes an extension plate, a clamping plate, a sliding groove, and a slider. An extension plate is slidably installed between the inner walls of both sides of the four mounting plates. An integrated clamping plate is fixedly connected to the end of each extension plate. The angle between the extension plate and the clamping plate is 90 degrees. A slider is fixedly connected to both sides of the extension plate near the end. A sliding groove is provided on the inner walls of both sides of the mounting plate. The slider is slidably engaged in the sliding groove. Several sets of rubber pads are fixedly provided on the side of the extension plate.

[0009] Preferably, four return springs are provided, and the four return springs are respectively fixed between the outer wall of the base and the end of the extension plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. In use, this utility model, through the sliding and adjustable extension plate and clamping plate structure, combined with the elastic extension and retraction of the return spring, can flexibly adjust the spacing between the horizontal and vertical clamping plates, and can adapt to insulation boards of different widths and lengths. It eliminates the need to equip a single specification of insulation board with a dedicated connector, greatly reduces material inventory, lowers procurement costs, and solves the problem of poor compatibility of traditional connectors.

[0012] In use, the base is quickly fixed by the engagement of the round shaft with the threaded hole in the wall, without the need for complicated tools; the spacing of the clamps can be adjusted simply by pulling them outward and then releasing them, which can be operated without professional skills, thus improving the installation efficiency of the insulation board.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-3As shown, an external wall insulation board connector is disclosed, including a base 1. Two circular shafts 5 extending to the back are slidably mounted on the front of the base 1. An mounting plate 2 is fixedly connected to the outer wall of the base 1. A return spring 11 is fixedly provided on the outer wall of the base 1. An adjustment component is provided inside the mounting plate 2. The base 1 is disc-shaped.

[0021] The base 1 has two circular grooves 7 extending to the back side. Two circular shafts 5 are slidably connected in the two circular grooves 7 respectively. The outer walls of the two circular shafts 5 are fixed with threads near their ends.

[0022] The back of the base 1 has an inner groove 8 corresponding to the two circular grooves 7. The ends of the two circular shafts 5 are fixed with caps 6, and the two caps 6 are slidably engaged in the two inner grooves 8.

[0023] There are four mounting plates 2 arranged in a cross shape. The disc-shaped base 1 can evenly transfer the force of the insulation board to the wall, avoiding damage to the wall or connectors caused by excessive local force. The cross-shaped mounting plates 2 and the four sets of clamping plates 4 form a symmetrical clamping structure, which further ensures the balance of the force on the insulation board and improves the reliability of the overall connection.

[0024] The adjustment assembly includes an extension plate 3, a clamping plate 4, a sliding groove 9, and a slider 10. Extension plates 3 are slidably mounted between the inner walls of the four mounting plates 2 on both sides. An integrated clamping plate 4 is fixedly connected to the end of each extension plate 3. The angle between the extension plate 3 and the clamping plate 4 is 90 degrees. Slider 10s are fixedly connected to the sides of the extension plates 3 near their ends. Sliding grooves 9 are provided on the inner walls of both sides of the mounting plates 2, and the sliders 10 are slidably engaged within the sliding grooves 9. Several sets of rubber pads 12 are fixed to the sides of the extension plates 3. A return spring 11 provides a continuous and stable clamping force, ensuring that the clamping plate 4 fits tightly against the insulation board. The sliders 10 on both sides of the extension plates 3 slide along the sliding grooves 9 of the mounting plates 2, ensuring a smooth adjustment process and preventing clamping deviation.

[0025] Four return springs 11 are provided. The four return springs 11 are respectively fixed between the outer wall of the base 1 and the end of the extension plate 3. During use, the return springs 11 can elastically stretch and contract to cope with the thermal expansion and contraction of the insulation board caused by temperature changes and the slight impact of external force. Dynamic adjustment is achieved by the slight sliding of the extension plate 3 to avoid stress concentration that could cause the insulation board to break or the connection to fail, thus extending the service life.

[0026] Working principle: First, align the two cylindrical shafts 5 with the pre-drilled threaded holes on the building wall. Rotate the cap 6 to drive the cylindrical shafts 5 to rotate within the circular groove 7 of the base 1. The cylindrical shafts 5 are gradually screwed into the threaded holes in the wall using the threads on their outer walls until the cap 6 is fully embedded in the inner groove 8 on the back of the base 1 and flush with the surface of the inner groove, thus completing the firm fixation of the base 1 to the wall. According to the width and length of the insulation board to be installed, pull the four clamping plates 4 outwards simultaneously. The clamping plates 4 drive the integrated extension plate 3 to move. The sliders 10 on both sides of the extension plate 3 slide smoothly along the sliding groove 9 on the inner wall of the mounting plate 2. The distance between the two sets of clamping plates 4 that are horizontally and vertically opposite each other increases until the distance is slightly larger than the size of the insulation board. During this process, the outer wall of the base 1 and the extension plate 3 are connected. The return spring 11 at the end is stretched synchronously and accumulates elastic potential energy; the insulation board is placed in the area enclosed by the four sets of clamps 4, and the clamps 4 are slowly released; the return spring 11 releases elastic potential energy, pulls the extension plate 3 along the slide groove 9 towards the base 1, and drives the clamps 4 to move closer to the edge of the insulation board until the clamps 4 tightly clamp the insulation board; at this time, the rubber pad 12 on the side of the clamps 4 undergoes elastic deformation due to compression, filling the contact gap between the clamps and the insulation board; during use, if the insulation board expands and contracts due to temperature changes, or is subjected to a slight impact from an external force, the return spring 11 can adapt by its own elastic extension and contraction, driving the extension plate 3 to slide slightly in the slide groove 9, ensuring that the clamps 4 always maintain a stable clamping force on the insulation board.
