Description
Technical Field
[0001] This utility model relates to the field of underfloor heating installation, and in particular to an EPP underfloor heating module that can be quickly assembled. Background Technology
[0002] EPP underfloor heating modules refer to modular insulation components made of EPP (Expanded Polypropylene) material, used for laying hot water pipes in underfloor heating systems. Their main functions are to support, limit, insulate, and provide energy-saving insulation for the underfloor heating pipes. EPP is an environmentally friendly, non-toxic, and recyclable high-performance foamed material with high strength, strong compressive and impact resistance, low thermal conductivity, high temperature resistance, and corrosion resistance. It is especially suitable for use as an insulation material in the field of building energy conservation.
[0003] In existing EPP underfloor heating modules, several circular protrusions are often set on the surface of the base plate to limit the installation of the underfloor heating pipes. Most of these protrusions only have a simple vertical limiting function and cannot effectively limit the underfloor heating pipes in the horizontal direction. During the installation process, the pipes may become dislodged due to vibration or sliding, requiring the dislodged parts to be rearranged and reinstalled, which is time-consuming and labor-intensive, and greatly affects the construction efficiency and installation reliability. Utility Model Content
[0004] The main objective of this invention is to propose a quick-assembly EPP underfloor heating module, which aims to solve the problems mentioned in the background art.
[0005] To address the aforementioned problems, this utility model proposes a rapidly assembleable EPP underfloor heating module, comprising a base plate, characterized in that: a plurality of first protrusions are spaced apart on the top surface of the base plate, a second protrusion is provided between each two adjacent first protrusions, and a first protrusion is provided between each two adjacent second protrusions; a connecting plate is fixedly provided on one side of the base plate, and underfloor heating pipes are installed in the gaps between the first and second protrusions.
[0006] In one embodiment, three mounting slots are spaced apart on the bottom surface of the grooved inner wall on one side of the base plate, and a ball-stop limiter is installed in each of the three mounting slots; On the top surface of the base plate, a limiting post is fixedly provided below each of the second protruding posts. An anti-detachment ring is fixedly provided at the top of the limiting post. The base plate is provided with multiple limiting grooves spaced apart circumferentially around each limiting post.
[0007] In one embodiment, the second protruding post includes a column body, the inner wall of which is provided with a sliding groove, and limiting blocks that match the limiting groove are fixedly provided on both sides of its bottom surface.
[0008] In one embodiment, the top of the limiting post is installed in a groove on the inner wall of the post, and the anti-detachment ring is used to prevent the limiting post from detaching from the groove.
[0009] In one embodiment, the bottom surface of the connecting plate is provided with three connecting rings at fixed intervals.
[0010] In one embodiment, the ball stopper includes a housing, a ball is installed on one side of the inner wall of the housing, a spring is fixedly disposed on one side of the ball, and the other end of the spring is fixedly connected to the inner wall of the cavity of the housing.
[0011] In one embodiment, every two of the ball-stopping limiters are installed in the mounting groove in opposite directions to achieve the bidirectional snap-fit function of the limiting structure.
[0012] Beneficial effects: 1. The module has a first protruding post and an elliptical second protruding post arranged alternately on the base plate. Combined with the limiting groove and limiting post structure located below, the underfloor heating pipe is three-dimensionally limited by a circumferential nesting and sliding engagement method. This can prevent the underfloor heating pipe from tilting and dislodging in the vertical direction and effectively limit its sliding in the horizontal direction, which significantly improves the stability and reliability of the installation.
[0013] 2. This device works in conjunction with a connecting plate located on the side edge of the base plate and a ball-operated limiter installed in the mounting groove. During assembly, simply press the connection point to achieve positioning and locking. After assembly, it automatically locks, providing excellent resistance to detachment. During disassembly, simply tilt and lift the module at a certain angle to release the ball-operated limiter, enabling quick unlocking and reassembly between modules, significantly shortening construction time and improving work efficiency.

[0017] 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.
[0018] To achieve the above-mentioned utility model objectives, such as Figure 1-5 As shown, this utility model provides a quick-assembly EPP underfloor heating module, including a base plate 1. The top surface of the base plate 1 is provided with several first protruding posts 2 spaced apart. A second protruding post 3 is provided between each two adjacent first protruding posts 2, and a first protruding post 2 is provided between each two adjacent second protruding posts 3. A connecting plate 5 is fixedly provided on one side of the base plate 1. Underfloor heating pipes 4 are installed in the gaps between the first protruding posts 2 and the second protruding posts 3. During operation, the first protruding posts 2 and the second protruding posts 3 on the base plate 1 are arranged in an alternating pattern to form mutually spaced limiting paths. The underfloor heating pipes 4 are inserted and installed by construction personnel along the gaps between the first protruding posts 2 and the second protruding posts 3, achieving nesting and fixation. The second protruding post 3 has an elliptical cylindrical structure, which can be lifted vertically and rotated to change its direction before being inserted into the limiting groove 12 provided on the base plate 1. The limiting blocks 32 on both sides of its bottom engage with the limiting groove 12, thereby limiting and fixing the underfloor heating pipes 4 in the horizontal direction and preventing dislocation.
[0019] The bottom surface of the grooved inner wall on one side of the base plate 1 has three spaced mounting slots 11, each containing a ball stopper 6. Each ball stopper 6 includes a housing 61, with a ball stopper 63 mounted on one side of the inner wall of the housing 61. A spring 62 is fixedly mounted on one side of the ball stopper 63, and the other end of the spring 62 is fixedly connected to the inner wall of the cavity of the housing 61. Two ball stoppers 6 are installed in opposite directions within the mounting slots 11 to achieve a bidirectional locking function of the limiting structure. During operation... When two floor heating modules are spliced together via connecting plate 5, connecting ring 51 is inserted into mounting groove 11 on one side of base plate 1 and pushes the ball 63 in ball limiter 6, causing it to compress spring 62 and retract inward, thus completing the snap-fit positioning of connecting ring 51. After the modules are assembled, ball 63 automatically rebounds under the action of spring 62, pressing against connecting ring 51 to form a reliable self-locking quick-installation connection. Since ball limiters 6 are set in pairs and face opposite directions, they can achieve bidirectional limiting of connecting rings, effectively preventing the connection from loosening or coming off.
[0020] On the top surface of the base plate 1, a limiting post 13 is fixedly installed below each of the second protruding posts 3. An anti-detachment ring 14 is fixedly installed at the top of the limiting post 13. The base plate 1 has multiple limiting grooves 12 spaced apart around each limiting post 13. During operation, the limiting post 13 passes through the sliding groove opened in the inner wall of the second protruding post 3 from bottom to top and is inserted into the limiting groove 12 set on the top surface of the base plate 1 to realize the vertical guidance and lateral position limitation of the second protruding post 3. The anti-detachment ring 14 is fixedly installed on the top of the limiting post 13. When the limiting post is inserted into the set position, the anti-detachment ring 14 will be locked at the end of the sliding groove of the second protruding post 3, effectively preventing the limiting post from detaching from the groove due to vibration or rebound, and ensuring the long-term stability and anti-loosening performance of the assembled structure.
[0021] The second protruding post 3 includes a post body 31. The inner wall of the post body 31 is provided with a sliding groove. Limiting blocks 32 that match the limiting groove 12 are fixedly provided on both sides of its bottom surface. The top of the limiting post 13 is installed in the sliding groove of the inner wall of the post body 31. The anti-detachment ring 14 is used to prevent the limiting post 13 from detaching from the sliding groove. During operation, the second protruding post 3 is designed to be lifted and rotated. The limiting blocks 32 provided on both sides of the bottom of the post body 31 can be rotated at a certain angle after being lifted and then inserted into the limiting groove 12 provided in the base plate 1 for quick engagement. The limiting post 13 is inserted into the sliding groove of the post body 31 and is vertically guided and positioned in conjunction with the sliding groove guide rail. Through structural cooperation, the second protruding post 3 can effectively fix the underfloor heating pipes during use and can also realize convenient connection and disassembly between modules through rotation and quick release, which improves construction efficiency and structural fastening performance.
[0022] The bottom surface of the connecting plate 5 is fixedly spaced with three connecting rings 51. During operation, the connecting plate 5 is used to assemble and connect with adjacent modules. The bottom surface of the connecting plate 5 is fixedly provided with multiple connecting rings 51. During assembly, the connecting rings 51 are inserted into the corresponding mounting slots 11 of the adjacent modules. The connecting rings push the ball limiters 6 in the mounting slots to form an elastic snap-fit, thereby achieving a firm mechanical quick-installation connection. When disassembly is required, the connecting plate only needs to be slightly lifted and tilted to release the ball spring lock, which facilitates quick replacement or module rearrangement on site.
[0023] The working principle of this utility model is as follows: This utility model forms a grid-like pipe groove structure by setting multiple first protruding posts 2 and detachable second protruding posts 3, which is used to effectively limit the underfloor heating pipe 4. During installation, the user first places the underfloor heating pipe 4 into the gap between the first protruding posts 2 and the second protruding posts 3 in sequence, and then lifts the second protruding post 3 and rotates it at a certain angle so that the limiting blocks 32 on both sides of its bottom are aligned with the limiting grooves 12 set on the top surface of the base plate 1 and inserted and locked, thereby completing the double limiting and fixing of the underfloor heating pipe 4 in the horizontal and vertical directions; the body of the second protruding post 3 is set as a column 31 structure, and the inner wall is provided with a sliding groove for guiding the insertion of the limiting post 13. The limiting post 13 is inserted into the sliding groove in the column 31 from below and passes through. Inserted into the limiting groove 12 on the base plate 1, after insertion, its top anti-detachment ring 14 will be locked on the upper edge of the sliding groove of the column 31 to prevent the limiting column 13 from coming out due to vibration or rebound, thereby further improving the connection firmness and structural stability; multiple mounting grooves 11 are opened on one side of the base plate 1 for embedding the ball limiter 6; the bottom of the connecting plate 5 is provided with several connecting rings 51. When splicing modules, the connecting rings 51 are inserted into the corresponding mounting grooves 11 of the adjacent modules and push the ball 63 in the ball limiter 6 to compress the spring 62 and retract to make room. After insertion, the ball 63 rebounds under the elastic force of the spring 62, locking the connecting ring 51 and realizing quick insertion limiting fixation between modules. During disassembly, simply lift the connecting plate 5 manually and tilt it slightly to release the ball stop, enabling quick unlocking and disassembly. The entire structure not only provides efficient positioning for the underfloor heating pipe 4, but also enables rapid installation, secure connection, and convenient disassembly between modular units, making it particularly suitable for modular and rapid installation of large-area underfloor heating systems.
[0024] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
