Description

Technical Field

[0001] This utility model belongs to the technical field of polyurethane sandwich panels, specifically relating to a polyurethane sandwich panel with a stable structure. Background Technology

[0002] Polyurethane sandwich panels are a type of composite panel with bimetallic, single-metallic, or non-metallic surfaces, using rigid polyurethane foam as the insulation layer. They typically consist of inner and outer fiberglass sheets and a core of rigid polyurethane foam, bonded together under high pressure using German vacuum technology. They possess excellent gloss retention and thermal insulation properties. Polyurethane sandwich panels have a variety of applications, primarily in energy-efficient industrial plants, civil buildings, and residences. They are widely used due to their good fire resistance, non-toxicity, odorlessness, and waterproofing. Furthermore, polyurethane sandwich panels can be made entirely of polyurethane or combined with color-coated steel sheets, making them the most widely used product system in external insulation systems for industrial and civil buildings.

[0003] Common polyurethane sandwich panel structures are relatively simple, usually directly connected to the fixing frame with bolts. When subjected to external impact and compression, the polyurethane sandwich panel is prone to deformation due to the lack of buffer space, resulting in insufficient stability. Furthermore, the position cannot be adjusted after installation, requiring disassembly and reinstallation, which greatly reduces installation efficiency and practicality. Utility Model Content

[0004] The purpose of this invention is to provide a polyurethane sandwich panel with a stable structure to solve the technical problems of insufficient stability and practicality in use, thereby improving the stability and practicality of use.

[0005] To solve the above-mentioned technical problems, this utility model provides a polyurethane sandwich panel with a stable structure, including a panel body, and a buffer mechanism is installed on the back of the panel body;

[0006] The buffer mechanism includes a fixed plate, and fixed blocks are symmetrically installed on the left and right sides of the back of the fixed plate near the top and bottom. A sliding rod is welded to the periphery of the fixed block. A connecting piece is slidably connected to the periphery of the end of the sliding rod away from the fixed plate. A buffer component is installed at the top of the connecting piece. A sliding groove is opened on the front of the connecting piece near the top.

[0007] Furthermore, threaded rods are welded to the front of the plate near the four corners. The threaded rods penetrate the front of the connector and are slidably connected to the slide groove. Nuts are threadedly connected to the outer periphery of the threaded rods and located on the front of the connector.

[0008] Furthermore, the back surface of the nut that contacts the connector has a frosted finish.

[0009] Furthermore, mounting holes are provided on the front side of the fixing plate near the four corners.

[0010] Furthermore, the end of the slide bar near the bottom is welded to the fixing block, and the fixing block is welded to the fixing plate.

[0011] Furthermore, the connector is an L-shaped metal structure with an anti-slip pad adhered to its back where it contacts the plate.

[0012] Furthermore, the buffer assembly includes a limiting rod, which is welded to a connecting piece. A connecting block is sleeved around the limiting rod and at the top of the sliding rod. The connecting block is welded to the sliding rod. A spring is sleeved around the limiting rod and between the connecting block and the connecting piece. The two ends of the spring are fixedly connected to the connecting block and the connecting piece, respectively.

[0013] The beneficial effects of this utility model are:

[0014] 1. When subjected to external compression and impact, the plate will push the connecting parts to move backward together, thereby buffering the compression force through the spring, allowing the plate to release pressure using the buffer space, thus reducing the damage caused by compression to the plate and improving the stability of use.

[0015] 2. After installation, when the arrangement of the panels needs to be adjusted, the fixing between the panels and the connectors can be loosened by turning the nuts, thereby making a slight adjustment to the position of the panels. After the adjustment is completed, turn the nuts again to fix the panels. Compared with the traditional fixing method, there is no need to disassemble and reassemble, which greatly improves the installation efficiency and effectively improves the practicality.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example:

[0024] like Figures 1 to 3 As shown, a polyurethane sandwich panel with a stable structure includes a panel body 1. A buffer mechanism 2 is installed on the back of the panel body 1. The buffer mechanism 2 includes a fixing plate 201. Fixing blocks 202 are symmetrically installed on the left and right sides of the back of the fixing plate 201 near the top and bottom. A sliding rod 203 is welded to the periphery of the fixing block 202. A connector 204 is slidably connected to the periphery of the end of the sliding rod 203 away from the fixing plate 201. A buffer assembly 205 is installed at the top of the connector 204. A groove 206 is opened on the front of the connector 204 near the top.

[0025] like Figures 1 to 3As shown, threaded rods 101 are welded to the front of the plate 1 near the four corners. The threaded rods 101 penetrate the front of the connector 204 and are slidably connected to the slide groove 206. Nuts 102 are threadedly connected to the outer periphery of the threaded rods 101 and located on the front of the connector 204. By rotating the nuts 102, they are made to fit tightly against the front of the connector 204, which can cooperate with the plate 1 to clamp the connector 204, thereby achieving the effect of fixing the plate 1, improving the stability of use and the convenience of installation. The back of the nut 102 has a frosted surface in contact with the connector 204. The sand-textured structure increases the friction between the nut 102 and the connector 204, preventing loosening during use and improving installation stability. Mounting holes 2011 are provided near the four corners on the front of the fixing plate 201. Bolts can be passed through these holes to secure the fixing plate 201, improving ease of use. The bottom end of the slide rod 203 is welded to the fixing block 202, and the fixing block 202 is welded to the fixing plate 201. The welding of the slide rod 203 to the fixing block 202, and the welding of the fixing block 202 to the fixing plate 201... The welding of the fixed plate 201 makes the connection between the slide rod 203, the fixing block 202, and the fixed plate 201 more secure, improving the stability of use. The connector 204 is an L-shaped metal structure, and an anti-slip pad is glued to the contact point between its back and the plate 1. The anti-slip pad design increases the friction between the connector 204 and the plate 1, thereby making the plate 1 more secure and improving the stability of use. The buffer assembly 205 includes a limiting rod 2051, which is welded to the connector 204. A connecting block is sleeved on the periphery of the limiting rod 2051 and located at the top of the slide rod 203. 2052, the connecting block 2052 is welded to the slide rod 203, and a spring 2053 is sleeved on the periphery of the limiting rod 2051 and between the connecting block 2052 and the connecting piece 204. The two ends of the spring 2053 are fixedly connected to the connecting block 2052 and the connecting piece 204 respectively. The limiting rod 2051 can limit the moving connecting piece 204 to prevent it from deviating and improve the stability of use. The spring 2053 can buffer the force of the connecting piece 204 moving backward, thereby providing a buffer space for the plate 1 and reducing the damage caused to the plate 1 by external squeezing and collision.

[0026] In summary, when using a polyurethane sandwich panel with a stable structure for external extrusion impact protection, the panel 1 will initially move the connector 204 towards the fixed plate 201 under the pressure of the extrusion. During this process, the spring 2053 can buffer the movement of the connector 204, and the limiting rod 2051 can limit the movement of the connector 204, preventing the fixed plate 201 from shifting during movement. This provides a buffer space for the panel 1, allowing it to release pressure and reducing the damage caused by the extrusion. To improve stability and ease of use, when the arrangement of the plate 1 needs to be adjusted after installation, the fixing between the plate 1 and the connector 204 can be loosened by rotating the nut 102. The position of the plate 1 can then be finely adjusted up and down by the threaded rod 101 and the slide groove 206. After the adjustment is completed, the nut 102 is rotated again to clamp the connector 204 with the plate 1, thus fixing the plate 1. Compared with the traditional fixing method, there is no need to disassemble and reassemble, which greatly improves the installation efficiency and effectively enhances the practicality.
