Description

Technical Field

[0001] This utility model relates to the field of water heating circulation technology, specifically a multi-loop pipe connection structure for a water heating circulation system. Background Technology

[0002] Hydronic heating is one type of radiant floor heating and one of the most popular heating methods. It uses hot water at a temperature not exceeding 60°C as the heat medium, which circulates within heating pipes to heat the floor. Heat is then transferred to the room through radiation and convection. Hydronic heating pipes are used in the installation of conduits in hydronic and electrical installation projects and are an auxiliary part of the project. The quality of their installation has a significant impact on the overall quality of the hydronic and electrical installation project.

[0003] Referring to the patent document: Patent Publication No. CN219082521U, Patent Publication Date 2023-05-26, a connection structure for plumbing fittings is disclosed, including plumbing fittings, a first connecting flange, and a second connecting flange. The first connecting flange is fixedly connected to the outer surface of one end of the plumbing fitting, and the second connecting flange is fixedly connected to the outer surface of the other end of the plumbing fitting. Fixing blocks are fixedly connected to both ends of the outer surface of the first connecting flange. An expansion block is slidably connected to the inside of the fixing block via an expansion groove. Reset grooves are provided on both sides of the expansion groove. When installing the plumbing fitting using the first and second connecting flanges, the first connecting flange is inserted into the installation groove inside the second connecting flange. After the sliding wheel is aligned with the slot and engaged, the first connecting flange is rotated, causing the sliding wheel to enter the inner position of the top groove. Subsequently, the reset spring pushes the sliding wheel into the inner part of the top groove, thereby realizing the installation and connection process of the plumbing fitting.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] In current water heating circulation systems, the common practice is to bend the manifold vertically and insert it directly into the main manifold connector, then tighten it with nuts. However, due to the lack of a structure to limit the arrangement of the manifold pipes, the elastic force generated by bending makes it difficult to accurately align the main and branch pipe interfaces during installation. This not only increases the difficulty of construction and prolongs the installation time, but also easily leads to poor sealing due to misalignment of the interfaces. Furthermore, the vertically installed manifold is prone to continuous shaking under its own weight and the impact of water flow, which continuously weakens the tightening effect of the nuts, causing the nuts at the connection to gradually loosen. This affects the stability of the connection structure and consequently affects the normal operation of the water heating circulation system.

[0006] Therefore, this utility model provides a multi-loop pipe connection structure for a water heating circulation system. Utility Model Content

[0007] To address the common problem in current water heating circulation systems where vertically bent manifolds are directly inserted into the main pipe joint and secured with nuts, leading to issues such as difficulty in aligning pipe connections, poor sealing, and unstable connections due to the bending elasticity of the manifold, its own weight, and the impact of water flow, this invention aims to provide a multi-loop pipe connection structure for water heating circulation systems.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a multi-loop pipe connection structure for a water heating circulation system, comprising a base, wherein a limiting mechanism is provided on the upper part of the base for limiting the end of the water distribution pipe used for water circulation, the limiting mechanism comprising:

[0009] The fixing component includes multiple limiting seats fixedly installed on the upper part of the base. Each of the multiple limiting seats has a set of symmetrically distributed movable seats slidingly attached to its upper part. Each set of movable seats has a tension spring fixedly installed on both sides. Each of the two tension springs has a limiting clamp fixedly installed at its top. Each of the multiple limiting seats has a set of fixing clamps that cooperate with each other on one side. A rotating shaft is rotatably installed on one side of the upper part of the base. The upper part of the rotating shaft has multiple sets of equally spaced positive and negative threads. The multiple sets of fixing clamps are threaded onto the upper part of the rotating shaft.

[0010] The mounting components are located at the bottom of the base to facilitate securing the base.

[0011] Preferably, the mounting assembly includes four evenly distributed centering plates fixedly installed on the lower part of the base. Each of the four centering plates has a movable plate on one side. The lower part of the base has two symmetrically distributed mounting seats. The top ends of the two mounting seats are fixedly installed on the bottom ends of the movable plates. The centering plates and the movable plates each have a slot in the middle. Each slot has two symmetrically distributed bolts slidably engaged in the middle. Each bolt has a nut threaded onto one side for mutual cooperation.

[0012] Preferably, the fixing assembly further includes multiple sets of connecting rods rotatably installed in the middle of the base, each of the multiple sets of movable seats having two symmetrically distributed limiting grooves on one side, and the upper parts of the multiple sets of connecting rods being slidably engaged in the middle of the limiting grooves.

[0013] Preferably, a sliding rod is fixedly installed on one side of each of the plurality of limiting seats, and one side of each of the plurality of limiting clamps is slidably engaged in the middle of the sliding rod.

[0014] Preferably, a limiting rod is fixedly installed on one side of the base, and the lower part of one side of multiple sets of fixing blocks is slidably locked in the middle of the limiting rod.

[0015] Preferably, each of the two mounting bases has two symmetrically distributed mounting holes on its upper sides for mounting its fixing bolts.

[0016] Beneficial effects

[0017] This utility model provides a multi-loop pipe connection structure for a water heating circulation system. Compared with the prior art, it has the following advantages:

[0018] 1. This application involves pressing the water distribution pipe into the middle of two limiting clamps. The tension of the spring drives the two moving seats to move towards the center, thus initially limiting the water distribution pipe with the limiting clamps. This limiting action guides and positions the water distribution pipe, preventing problems such as misalignment and poor sealing caused by the bending elasticity of the water distribution pipe with the main pipe interface. After installation, rotating the shaft causes the multiple sets of positive and negative threads on its upper part to move the fixed clamps synchronously relative to each other, thus performing secondary tightening on the multi-loop distribution pipes. This prevents the nut tightening effect from weakening due to the weight of the water flow and other factors during long-term use, ensuring long-term stability of the connection and guaranteeing the normal operation of the water heating circulation system.

[0019] 2. This application moves a movable plate along a centering plate, then uses bolts to pass through the slots in the middle of the movable plate and the centering plate, and tightens the nuts. The movable plate is firmly fixed by the mutual clamping of the nuts and bolts, thereby locking the position of the mounting base. This allows the relative position of the mounting base and the base to be precisely adjusted according to the actual distance between the water pipe and the wall, so that the fixing components can adapt to different installation environments and needs, making the device more convenient and practical in actual use.

[0026] 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.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a multi-loop pipe connection structure for a water heating circulation system, including a base 1, and a limiting mechanism 2 on the upper part of the base 1 for limiting the end of the water distribution pipe for water circulation. The limiting mechanism 2 includes:

[0028] The fixing component 21 includes multiple limiting seats 211 fixedly installed on the upper part of the base 1. Each of the multiple limiting seats 211 has a set of symmetrically distributed movable seats 212 slidably mounted on its upper part. Each movable seat 212 has a tension spring 215 fixedly installed on both sides. The two ends of the tension spring 215 are respectively fixedly installed on opposite sides of one side of two movable seats 212, which can drive the two movable seats 212 to move towards the center relative to each other under the tension of the tension spring 215. The top of each tension spring 215 is fixedly installed with a limiting clamp 216. Each of the multiple limiting seats 211 has a set of fixed clamping blocks 218 that cooperate with each other on one side. A rotating shaft 217 is rotatably installed on the upper side of the base 1. The upper part of the rotating shaft 217 has multiple sets of equally spaced positive and negative threads. The multiple sets of fixed clamping blocks 218 are threaded on the upper part of the rotating shaft 217. The lower part of each set of fixed clamping blocks 218 is threaded on each set of positive and negative threads, so that when the rotating shaft 217 is rotated, the fixed clamping blocks 218 can be moved relative to each other through the positive and negative threads to clamp and fix the branch pipe.

[0029] Mounting component 22 is located at the lower part of base 1 to facilitate fixing base 1.

[0030] The mounting assembly 22 includes four evenly distributed centering plates 224 fixedly mounted on the lower part of the base 1. Each of the four centering plates 224 has a movable plate 223 on one side. The lower part of the base 1 has two symmetrically distributed mounting seats 221. The tops of the two mounting seats 221 are fixedly mounted on the bottom of the movable plates 223. The centering plates 224 and the movable plates 223 each have a slot 227 in the middle. Two symmetrically distributed bolts 225 are slidably engaged in the middle of the slots 227. Each bolt 225 has a nut 226 threaded on one side for mutual cooperation. By tightening the nut 226 on one side of the centering plate 224, the movable plate 223 is fixed by clamping friction under the mutual clamping of the nut 226 and the bolt 225, thereby adjusting the relative position of the base 1 and the mounting seat 221.

[0031] The fixed assembly 21 also includes multiple sets of connecting rods 213 rotatably installed in the middle of the base 1. Each set of movable seats 212 has two symmetrically distributed limiting grooves 2131 on one side. The upper part of each set of connecting rods 213 is slidably locked in the middle of the limiting groove 2131. Each set of connecting rods 213 is arranged in a cross shape and consists of two pull rods. The middle part of the two pull rods rotates relative to each other, so that the two pull rods form a cross-shaped connecting rod 213 structure. Thus, when the two movable seats 212 move relative to each other, the limiting groove 2131 limits the two movable seats 212, so that the two movable seats 212 move synchronously.

[0032] A sliding rod 214 is fixedly installed on one side of each of the multiple limiting seats 211, and one side of each of the multiple limiting clamps 216 is slidably locked in the middle of the sliding rod 214. By setting the sliding rod 214, the limiting clamps 216 can be limited, so that under the spring tension of the tension spring 215, the limiting clamps 216 can move stably relative to limit the water pipe.

[0033] A limiting rod 219 is fixedly installed on one side of the base 1. The lower part of one side of multiple sets of fixing blocks 218 is slidably locked in the middle of the limiting rod 219. The limiting rod 219 can limit and fix one side of the fixing blocks 218, making the two fixing blocks 218 more stable when they move relative to each other to fix the water pipe.

[0034] Two symmetrically distributed mounting holes 222 are provided on both sides of the upper part of the two mounting bases 221 for mounting the fixing bolts. The mounting bases 221 can be fixed by passing the fixing bolts through the mounting holes 222 and tightening them on the cavity. In other words, the fixing components 21 can be installed on the wall located on one side of the water pipe.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, the mounting base 221 can be adjusted according to the distance between the branch pipe and the wall. By moving the moving plate 223, the distance between the mounting base 221 and the base 1 can be adjusted along the centering plate 224, thereby adjusting the position between the fixing component 21 and the wall to facilitate the limiting of the branch pipe. After the position is adjusted, the bolt 225 passes through the groove 227 in the middle of the moving plate 223 and the centering plate 224, and the other end is threaded with a nut 226, so that the nut 226 and the bolt are in contact. Under the limit of 225, the movable plate 223 is limited and fixed, that is, the position of the mounting base 221 is fixed. At the same time, when the bolt 225 is installed, the upper bolt 225 is stuck in the upper end of the slot 227 opened in the movable plate 223, while the lower bolt 225 is stuck in the lower end of the slot 227 opened in the centering plate 224. After the position is fixed, the mounting base 221 can be fixedly installed on the wall by passing the fixing bolt through the mounting hole 222, thereby completing the fixing work of the base 1.

[0037] At this point, multiple branch pipes can be pressed and squeezed into the middle of the two limiting clamps 216. Under the spring tension of the tension spring 215, the two limiting clamps 216 can move relative to each other, clamping and fixing the branch pipes inserted in the middle. At this time, the operator can connect the branch pipes after limiting them to the main pipe of the water distributor. Under the limitation of the limiting clamps 216, the installation alignment can be more accurate, and it can assist in the installation connection of the main pipe and the branch pipes. It can also avoid the connection operation of the pipes being affected by the messy vertical pipe distribution and the failure to stand vertically when not fixed. After the pipe connection is completed, by rotating the rotating shaft 217, since the upper part of the rotating shaft 217 has multiple sets of positive and negative threads, multiple sets of fixing clamps 218 can move relative to each other synchronously, clamping and fixing the multi-loop diversion pipes, thus completing the limiting work. This prevents the connection from loosening due to shaking caused by its own weight and water flow impact during long-term use.
