Description

Technical Field

[0001] This utility model relates to the field of radiant fresh air equipment technology, and in particular to a capillary network installation structure for a radiant fresh air system. Background Technology

[0002] In modern building environments, radiant ventilation systems, as a highly efficient and energy-saving temperature control and ventilation technology, have been widely used in green buildings and spaces with high comfort requirements. Among these systems, capillary networks, as the core heat transfer element, directly affect the system's heat exchange efficiency, operational stability, and ease of maintenance through their installation structure. However, in current technologies, capillary networks are often installed by directly fixing them to the mounting surface. This method requires a high degree of flatness in the mounting surface, but in actual construction, mounting surfaces such as walls or ceilings often have varying degrees of unevenness or localized bumps, preventing the capillary network from adhering tightly to the mounting surface. This affects heat transfer uniformity and may even cause localized stress concentration, increasing the risk of pipe damage. Utility Model Content

[0003] The purpose of this utility model is to provide a capillary network installation structure for a radiant fresh air system, which can avoid the problem of high requirements for the flatness of the installation surface in traditional installation methods.

A fixing buckle is fixedly connected to the outer wall of the end of the capillary tube near the interface. The fixing buckle is used to connect and store the capillary tube. A mounting bracket is provided on the outer wall of the end of the capillary tube away from the fixing buckle. A base plate is fixedly connected to the lower side of the mounting bracket. A slide rail is fixedly connected to the lower side of the base plate. A support plate is slidably connected to the inner wall of the slide rail.

[0005] Preferably, a support foot is fixedly connected to the end of the support plate away from the slide rail. The support foot is trapezoidal in design.

[0007] Preferably, a rotating rod is rotatably connected to the upper side of the mounting bracket, and the outer wall of the rotating rod away from the mounting bracket is fixedly connected to the side of the handle close to the mounting bracket.

[0008] Preferably, a gear is fixedly connected to the end of the rotating rod away from the handle, the gear teeth are meshed with a toothed plate, and the outer wall of the toothed plate is slidably connected to the inner wall of the mounting bracket.

[0009] Preferably, a push plate is fixedly connected to the end of the toothed plate away from the handle, and a locking plate is fixedly connected laterally to the end of the push plate away from the toothed plate. A locking groove is provided at the lower end of the fixing buckle, and the size of the internal space of the locking groove is adapted to the size of the locking plate.

[0010] Preferably, an extrusion plate is fixedly connected to the inner wall of the mounting frame, the side wall of the extrusion plate is slidably connected to the outer wall of the capillary tube, an extrusion block is slidably connected to the bottom wall of the mounting frame, the side wall of the extrusion block is slidably connected to the outer wall of the capillary tube, and the extrusion plate and the side wall of the extrusion block are in contact with each other to extrude the capillary tube.

[0012] The beneficial effects of this application are:

[0013] 1. The capillary network installation structure of this radiant fresh air system, through the combination of an elastic support adjustment structure and trapezoidal support feet, allows the capillary network installation structure to adapt to various uneven or inclined installation environments. The support plate slides within the slide rail and, in conjunction with a first spring, achieves automatic height adjustment, ensuring that the capillary duct remains horizontal at all times, thus improving installation stability and applicability. Simultaneously, the anti-slip pad design effectively prevents slippage during installation, enhancing construction safety and reliability.

[0014] 2.

Under the action of the second spring, the clamping is automatically released, restoring the capillary tubes to their flow state. This design not only improves the operating efficiency during the initial startup of the system but also achieves automatic switching between exhaust and flow states, enhancing the overall intelligence level of installation and ease of operation.

[0025] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] Please refer to Figures 1 to 4This utility model provides a capillary network installation structure for a radiant fresh air system, including a capillary tube 101. A fixing buckle 102 is fixedly connected to the outer wall of the capillary tube 101 near the interface, used for connecting and housing the capillary tube 101 and serving as a cooperating component for subsequent locking structures. A mounting bracket 201 is provided on the outer wall of the end of the capillary tube 101 away from the fixing buckle 102, serving as the base platform for the overall support structure. A base plate 202 is fixedly connected to the lower side of the mounting bracket 201, and a slide rail 203 is fixedly connected to the lower side of the base plate 202. A support plate 204 is slidably connected to the inner wall of the slide rail 203, and a support foot 205 is fixedly connected to the end of the support plate 204 away from the slide rail 203. The support foot 205 adopts a trapezoidal design, allowing it to better adapt to uneven or inclined installation surfaces and enhance structural stability. An anti-slip pad is also fixedly connected to the end of the support foot 205 away from the support plate 204 to increase friction with the installation surface and prevent slippage during installation.

[0027] Furthermore, a first spring 206 is fixedly connected to the end of the support plate 204 away from the support foot 205, and the other end of the first spring 206 is fixedly connected to the inner wall of the slide rail 203, providing elastic buffering for the support structure. When the mounting frame 201 is affected by external pressure or terrain undulations, the support plate 204 can slide up and down within the slide rail 203 and compress or stretch the first spring 206, thereby automatically adjusting the support height and keeping the capillary tube 101 in a horizontal state, improving installation adaptability and stability.

[0028] To facilitate handling and installation, a handle 301 is provided on the upper side of the mounting frame 201, allowing workers to move or adjust the position of the entire mounting structure by gripping the handle 301. An insertion slot 302 is provided on the inner wall of the handle 301, and a mounting plate 303 is fixedly connected to the upper end of the fixing buckle 102. The size of the insertion slot 302 is adapted to the mounting plate 303, allowing the handle 301 to engage and lock with the fixing buckle 102. Furthermore, a rotating rod 401 is rotatably connected to the upper side of the mounting frame 201. One end of the rotating rod 401 is fixedly connected to the side of the handle 301 near the mounting frame 201, and the other end is fixedly connected to a gear 402. The teeth of the gear 402 mesh with a gear plate 403, which is slidably connected to the inner wall of the mounting frame 201, forming a complete mechanical transmission mechanism.

[0029] In actual operation, when the worker grasps the handle 301 and slides the mounting bracket 201 along the capillary tube 101 to the side of the fixing buckle 102, they rotate the handle 301 to align the insertion port 302 with the insertion plate 303 and insert it to complete the initial connection. At this time, the handle 301 drives the rotating rod 401 to rotate, which in turn drives the gear 402 to rotate, pushing the toothed plate 403 to move upward. The movement of the toothed plate 403 will drive the push plate 404 connected to it to move, ultimately pushing the locking plate 405 upward, so that it is embedded in the slot 406 below the fixing buckle 102, completing the final locking and fixing. This linkage structure not only improves the installation efficiency, but also ensures the firmness and safety of the connection.

[0030] Please refer to Figures 1 to 4 An extrusion plate 501 is fixedly connected to the inner wall of the mounting bracket 201 near the capillary tube 101. The side wall of the extrusion plate 501 slides against the outer wall of the capillary tube 101 to apply a certain extrusion force. At the same time, an extrusion block 502 is slidably connected to the bottom wall of the mounting bracket 201, and its side wall also adheres to the outer wall of the capillary tube 101, forming a clamping engagement with the extrusion plate 501.

[0031] In the initial state, the gap between the extrusion block 502 and the extrusion plate 501 is small, and the two are in close contact, jointly applying moderate pressure to the capillary tube 101, thereby achieving the initial clamping of the capillary tube 101 and the air expulsion operation. In order to control the sliding displacement of the extrusion block 502, a limit rod 503 is fixedly connected to the inner wall of the mounting bracket 201 away from the extrusion plate 501. The limit rod 503 slides through and is slidably connected to the inner wall of the extrusion block 502, providing it with guiding support. A second spring 504 is fixedly connected between the side of the extrusion block 502 away from the extrusion plate 501 and the inner wall of the mounting bracket 201. This spring is sleeved on the outside of the limit rod 503, providing a restoring force for the extrusion block 502.

[0032] In addition, in the linkage locking mechanism of handle 301, there is a push plate 404, and a baffle 505 is fixedly connected to its side wall. The end of the baffle 505 away from the push plate 404 abuts against the outer wall of the pressing block 502 away from the pressing plate 501, which plays a limiting and blocking role.

[0033] When the operator grasps the handle 301 and slides the mounting bracket 201 along the direction of the capillary tube 101 to the side of the fixing buckle 102, the extrusion plate 501 and the extrusion block 502 apply pressure to the capillary tube 101, gradually squeezing out any air that may be present inside, preventing air bubbles from affecting the flow efficiency of the cooling medium during subsequent operation. Then, rotating the handle 301 aligns the inlet 302 with the inlet plate 303, and the gear 402 drives the toothed plate 403 to move, ultimately pushing the push plate 404 upwards. At this time, the baffle 505 on the push plate 404 moves upwards simultaneously and disengages from limiting the extrusion block 502. After the baffle 505 is released, the second spring 504 begins to release its elasticity, pushing the extrusion block 502 to slide away from the extrusion plate 501 along the limiting rod 503, thus separating it from the extrusion plate 501, releasing the extrusion of the capillary tube 101, reopening its internal space, and facilitating the smooth inflow and circulation of the cooling medium.

[0034] In summary, the working principle of the capillary network installation structure of the radiant fresh air system according to this utility model embodiment is as follows: Before installation, the operator holds the handle 301 provided on the upper part of the mounting bracket 201 and slides the entire installation structure along the direction of the capillary tube 101 to the side of the fixing buckle 102. At this time, the extrusion plate 501 and extrusion block 502 inside the mounting bracket 201 are in an initial clamping state, and the two are attached to the outer wall of the capillary tube 101, applying appropriate pressure to achieve the initial discharge of air inside the capillary tube 101, preventing air bubbles from affecting the subsequent flow of cooling medium.

[0035] Subsequently, the handle 301 is rotated so that the insertion port 302 on its inner wall aligns with the insertion plate 303 at the upper end of the fixing buckle 102 and completes the insertion and docking. The handle 301 drives the rotating rod 401 to rotate, which in turn drives the gear 402 connected to it to rotate. The gear 402 meshes with the toothed plate 403 slidably connected to the inner wall of the mounting bracket 201, pushing the toothed plate 403 to move upward. The toothed plate 403 further drives the push plate 404 to move upward, and the baffle 505 fixed to the side wall of the push plate 404 is released from its limiting effect on the extrusion block 502. At this time, the previously compressed second spring 504 begins to release its elastic force, pushing the extrusion block 502 to slide away from the extrusion plate 501 along the limiting rod 503, thereby releasing the clamping state on the capillary tube 101, reopening its internal space, and preparing for the subsequent inflow of the refrigerant.

[0036] Simultaneously, the upward movement of the push plate 404 also causes the locking plate 405 to move upward synchronously, and finally embeds into the slot 406 below the fixing buckle 102, completing the locking and fixing of the entire installation structure and the interface of the capillary tube 101. This linkage mechanism not only improves installation efficiency, but also ensures the firmness and sealing of the connection.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
