Description

Technical Field

[0001] This utility model relates to the field of garden irrigation equipment technology, and in particular to a garden multi-interface water pipe diverter structure. Background Technology

[0002] In landscaping and home gardening irrigation systems, to meet the water requirements of vegetation in different areas, water pipe distributors are typically used to distribute a single main water source to multiple branch pipes. Most existing distributors and connecting pipes use a standard threaded connection method. This connection method is simple in structure, easy for users to install or disassemble quickly when needed, and is currently the most common connection method on the market.

[0003] However, this traditional connection structure has significant limitations in practical applications. Due to the specific nature of garden irrigation operations, the connecting pipe often needs to be dragged long distances across grass or ground as the user moves, subjecting the connection between the distributor and the connecting pipe to frequent tensile, torsional, and vibration forces from different directions. Simultaneously, fluctuations in water pressure within the pipe also exert continuous impact on the connection area. Existing threaded connections primarily rely on the friction between the threads and the preload of the internal static sealing gasket to maintain sealing and fixation, lacking proactive anti-loosening mechanisms and adaptive compensation capabilities.

[0004] Under the combined effects of external drag and internal water pressure over a long period, simple threaded connections are prone to slight relative rotation, leading to gradual loosening. Once loosened, the internal sealing gasket cannot maintain sufficient contact pressure, causing seepage or leakage at the connection. More seriously, under strong external pulling forces, the loosened connecting pipe may even detach directly from the distributor, causing irrigation interruption and water waste. Therefore, designing a connection structure that can effectively resist external mechanical pulling to prevent loosening while adapting to internal pressure changes and maintaining a long-term seal has become an urgent problem to be solved.

[0005] Therefore, this utility model proposes a multi-interface water pipe diverter structure for gardens to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a multi-interface water pipe diverter structure for gardens, aiming to improve the structural defects of existing garden water pipe connections, which are prone to loosening and detachment due to water pressure impact or external dragging, and simple threaded connections are prone to leakage due to decreased sealing performance after long-term use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a garden multi-interface water pipe diverter structure, comprising: a diverter body, a diverter port fixedly connected to the surface of the diverter body, and a connecting pipe connected to the outer surface of the diverter port.

[0008] The diversion port has an insertion cavity and an inner cavity communicating with the inside of the insertion cavity. A sliding rod is fixedly connected to the bottom of the inner wall of the inner cavity. A sleeve is slidably connected to the outer surface of the sliding rod. A sealing expansion ring is fixedly connected to the end of the sleeve. The sealing expansion ring is located at the bottom of the inner wall of the insertion cavity. A return spring is sleeved on the outer surface of the sliding rod between the sleeve and the bottom of the inner wall of the inner cavity. The two ends of the return spring abut against the end face of the sleeve and the bottom of the inner wall of the inner cavity, respectively.

[0009] Furthermore, a fixing ring is fixedly connected to the outer side of the diversion port, and threaded rods are threadedly connected to the two sides of the fixing ring housing. A clamping ring is rotatably connected to the inner end of the threaded rod. Slide rails are provided on the upper and lower sides of the inner wall of the fixing ring, and sliders are fixedly connected to the upper and lower ends of the clamping ring. The sliders are slidably connected to the slide grooves opened inside the slide rails. The clamping ring, the sliders, and the fixing ring form a radially guiding movement structure through the cooperation of the slide rails and the slide grooves.

[0010] Preferably, the inner wall of the connecting pipe is provided with an internal thread, and the outer surface of the diversion port is provided with an external thread. The internal thread and the external thread are threaded together, and the basic mechanical connection between the connecting pipe and the diversion port is realized by the thread engagement.

[0011] Preferably, the two sides of the housing of the fixing ring are provided with threaded holes that cooperate with the threaded rod. The outer end of the threaded rod is fixedly connected to a knob. By rotating the knob, the threaded rod is driven to rotate in the threaded hole and move forward and backward along the axial direction, thereby pushing the clamping ring to move.

[0012] Preferably, rollers are rotatably connected to both sides of the slider, and the outer circumferential surface of the rollers makes rolling contact with the inner wall of the groove. The rollers convert the sliding friction of the slider in the groove into rolling friction, thereby reducing the moving resistance.

[0013] Preferably, a rubber pad is fixedly connected to the inner side of the clamping ring, and the inner surface of the rubber pad abuts against the outer surface of the connecting tube. The rubber pad increases the friction between the rubber pad and the connecting tube and protects the tube wall from damage by hard materials.

[0014] Preferably, the outer diameter of the sealing expansion ring is equal to the inner diameter of the insertion cavity, and the sealing expansion ring is made of elastic rubber material to ensure that it can be smoothly accommodated in the insertion cavity and has sufficient radial expansion deformation capacity when under pressure.

[0015] Preferably, the clamping ring has a semi-circular arc structure, and the two sets of clamping rings are symmetrically arranged about the axis of the connecting pipe, so as to form a wrapping clamping and fixing of the connecting pipe from both sides.

[0016] Preferably, the slide rail and the slide groove extend along the radial direction of the fixing ring to limit the clamping ring to only approach or move away from the connecting pipe in the radial direction, thereby ensuring the accuracy of the clamping action.

[0017] Preferably, the connecting tube passes through the inner ring space of the fixing ring and extends into the insertion cavity, with the end face of the connecting tube abutting against the surface of the sealing expansion ring, so that when the connecting tube is screwed in, an axial compressive force can be directly applied to the sealing expansion ring.

[0018] This utility model has the following beneficial effects: 1. In this utility model, an adaptive sealing assembly consisting of a slide rod, sleeve, sealing expansion ring and return spring is set inside the diversion port. When the connecting pipe is screwed in, the sealing expansion ring is axially squeezed and the return spring is compressed. The reaction force of the spring forces the sealing expansion ring to undergo radial expansion deformation. This solves the problem that the existing technology, which relies solely on threaded connection, is prone to leakage due to wear or water pressure impact. It achieves the technical effect of automatically filling the connection gap with the expanded volume and realizing long-term stable and efficient sealing.

[0019] 2. In this utility model, by setting an external clamping mechanism including a fixing ring, a threaded rod, a knob and a clamping ring outside the diversion port, the clamping ring is driven to move radially and hold the connecting pipe by rotating the knob. This solves the problem that the existing garden water pipe connection is prone to loosening or even falling off due to external force dragging or vibration. It achieves the technical effect of secondary mechanical locking of the connecting pipe and significantly improves the connection firmness and tensile strength.

[0020] 3. In this utility model, by setting a slide rail on the inner wall of the fixed ring and setting a slider with rollers on the clamping ring, the movement trajectory of the clamping ring is restricted by the cooperation between the slider and the slide rail. At the same time, the sliding friction is converted into rolling friction by the rollers, which solves the problem that the clamping mechanism is prone to deflection and jamming or large operating resistance during the movement process. It achieves the technical effect of ensuring smooth and stable clamping action, improving the convenience of operation and clamping accuracy. Attached Figure Description

[0023] 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.

[0024] Example: Please refer to Figures 1 to 4 This utility model provides a multi-interface water pipe diverter structure for gardens, which aims to solve the structural defects of existing garden water pipe connections that are prone to loosening and detachment due to water pressure impact or external force dragging, and simple threaded connections that are prone to leakage due to decreased sealing performance after long-term use.

[0025] like Figure 1 and Figure 2 As shown, the garden multi-port water pipe diverter structure includes a diverter body 1 and a diverter port 2 fixedly connected to the surface of the diverter body 1. The diverter body 1 serves as the water source collection and distribution base for the entire device, used to connect to the main water source and guide the water flow to various branch directions. The diverter port 2 serves as the diversion output port, used to connect to external irrigation pipelines.

[0026] The connecting pipe 3 is connected to the outer surface of the diversion port 2. The connecting pipe 3 is used to establish a fluid channel with the diversion port 2 and extend to the irrigation area. Specifically, the inner wall of the connecting pipe 3 is provided with an internal thread 301, and the outer surface of the diversion port 2 is provided with an external thread 203. The internal thread 301 and the external thread 203 are threaded together. By rotating the connecting pipe 3, it is screwed onto the diversion port 2, thus achieving the initial mechanical fixation and connection between the two.

[0027] To achieve a deep seal and anti-loosening reinforcement at the connection, the structure of the diversion port 2 is specially designed. The inside of the diversion port 2 is provided with a plug-in cavity 201 and an inner cavity 202 connected to the inside of the plug-in cavity 201. The plug-in cavity 201 is located at the port of the diversion port 2 and is used for the insertion of the end of the connecting tube 3. The inner cavity 202 is located deep in the plug-in cavity 201 and is used to accommodate the internal elastic sealing component.

[0028] Meanwhile, a fixing ring 4 is fixedly connected to the outside of the port 2. The fixing ring 4 serves as the mounting carrier for the external clamping mechanism. Its inner space is large enough for the connecting pipe 3 to pass through. The connecting pipe 3 passes through the inner space of the fixing ring 4 and extends into the insertion cavity 201. After the threaded connection is completed, the outer surface of the connecting pipe 3 is surrounded by the fixing ring 4, which provides a structural basis for applying radial clamping force to the connecting pipe 3 through the components on the fixing ring 4.

[0029] A slide rod 206 is fixedly connected to the bottom of the inner wall of the inner cavity 202. The slide rod 206 extends along the axial direction of the inner cavity 202, providing a linear guide reference for the movement of the internal components. A sleeve 205 is slidably connected to the outer surface of the slide rod 206. The sleeve 205 can reciprocate linearly along the length of the slide rod 206. A sealing expansion ring 204 is fixedly connected to the end of the sleeve 205 away from the bottom of the inner cavity 202. The sealing expansion ring 204 is located at the bottom of the inner cavity 201. The sealing expansion ring 204 is made of elastic rubber material, and its outer diameter is equal to the inner diameter of the cavity 201, so as to maintain its natural shape and be accommodated in the cavity when not under pressure.

[0030] In order to give the sealing assembly an active abutment force and rebound potential energy, a return spring 207 is sleeved on the outer surface of the slide rod 206 and between the sleeve 205 and the bottom of the inner wall of the inner cavity 202. The two ends of the return spring 207 abut against the end face of the sleeve 205 and the bottom of the inner wall of the inner cavity 202, respectively, and provide a continuous axial thrust to the sleeve 205 through its own elastic deformation capability.

[0031] In the assembled and used state, the end face of the connecting pipe 3 abuts against the surface of the sealing expansion ring 204. When the connecting pipe 3 is screwed into the diversion port 2, the connecting pipe 3 axially compresses the sealing expansion ring 204, causing the sleeve 205 to slide inward along the slide rod 206 and compress the return spring 207. The reaction force generated by the return spring 207 pushes the sealing expansion ring 204 in the opposite direction through the sleeve 205, forcing the sealing expansion ring 204 to undergo radial expansion deformation while being axially compressed, so that it fits tightly between the outer surface of the port of the connecting pipe 3 and the inner wall of the insertion cavity 201. The expanded volume fills the gap, thereby achieving an adaptive tight sealing effect and effectively preventing water leakage.

[0032] In a preferred embodiment, in order to achieve mechanical clamping and fixing of the connecting pipe 3 to the outside and prevent it from loosening due to external force, the two side shells of the fixing ring 4 are threadedly connected to threaded rods 408. The two side shells of the fixing ring 4 are provided with threaded holes 403 that cooperate with the threaded rods 408. The outer end of the threaded rod 408 is fixedly connected to a knob 409. By rotating the knob 409, the threaded rod 408 can be driven to move forward and backward along the axial direction. The inner end of the threaded rod 408 is rotatably connected to a clamping ring 404, so that when the threaded rod 408 is rotated forward, it can push the clamping ring 404 to move, while the clamping ring 404 itself does not rotate with the threaded rod 408, but only performs translational movement.

[0033] As another preferred embodiment, in order to ensure the smooth movement of the clamping ring 404 and provide guiding support, the upper and lower sides of the inner wall of the fixed ring 4 are provided with slide rails 401. The slide rails 401 extend along the radial direction of the fixed ring 4. The upper and lower ends of the clamping ring 404 are fixedly connected with sliders 406. The sliders 406 are slidably connected in the slide grooves 402 opened inside the slide rails 401. The slide grooves 402 also extend radially. Through the cooperation of the sliders 406 and the slide grooves 402, the degree of freedom of the clamping ring 404 is restricted, so that it can only move closer to or away from the connecting pipe 3 in a radial straight line.

[0034] As a further preferred embodiment, in order to reduce the frictional resistance of the slider 406 when sliding in the groove 402 and improve the operating feel, rollers 407 are rotatably connected to both sides of the slider 406. The outer circumferential surface of the rollers 407 rolls into contact with the inner wall of the groove 402, converting sliding friction into rolling friction, making the clamping action smoother and less strenuous.

[0035] In another preferred embodiment, to enhance the gripping force of the clamping ring 404 on the connecting pipe 3 and prevent damage to the pipe wall, the clamping ring 404 has a semi-circular arc structure, and the two sets of clamping rings 404 are symmetrically arranged about the axis of the connecting pipe 3 so as to cover the connecting pipe 3 from both sides. A rubber pad 405 is fixedly connected to the inner side of the clamping ring 404. The inner surface of the rubber pad 405 abuts against the outer surface of the connecting pipe 3. The inner surface of the rubber pad 405 is provided with anti-slip texture. The high coefficient of friction of rubber and the anti-slip texture increase the static friction between the rubber and the connecting pipe 3, thereby achieving a firm locking effect.

[0036] Working principle: When in use, the operator first inserts the connecting tube 3 into the insertion cavity 201 of the diversion port 2. By rotating the connecting tube 3, the internal thread 301 and the external thread 203 are engaged to make the connecting tube 3 gradually screw into the depth of the diversion port 2. As the connecting tube 3 is screwed in, the end face of the connecting tube 3 contacts and abuts against the surface of the sealing expansion ring 204.

[0037] Continue tightening the connecting pipe 3. The connecting pipe 3 pushes the sealing expansion ring 204 and the sleeve 205 axially along the slide rod 206 toward the bottom of the inner cavity 202. At this time, the sleeve 205 compresses the return spring 207. The return spring 207 generates a reverse elastic force under pressure. This reverse elastic force acts on the sealing expansion ring 204 through the sleeve 205, so that the sealing expansion ring 204 is axially squeezed under the combined action of the thrust of the connecting pipe 3 and the resistance of the return spring 207. After being compressed, the sealing expansion ring 204 undergoes radial expansion deformation and tightly fills the gap between the outer wall of the connecting pipe 3 and the inner wall of the insertion cavity 201, thereby achieving an adaptive and efficient seal and preventing water leakage from the connection.

[0038] After the water pipe connection and sealing are completed, in order to prevent the connecting pipe 3 from loosening, the operator rotates the knobs 409 on both sides of the fixing ring 4. The knobs 409 drive the threaded rod 408 to rotate, which in turn drives the clamping ring 404 to move radially inward toward the connecting pipe 3. During this process, the slider 406 slides in the groove 402, and the roller 407 rolls on the inner wall of the groove 402, ensuring the stability and directional accuracy of the movement of the clamping ring 404.

[0039] As the clamping ring 404 is advanced, the rubber pad 405 on the inner side of the clamping ring 404 fits tightly against the outer surface of the connecting pipe 3. The friction generated by the anti-slip texture on the surface of the rubber pad 405, as well as the mechanical clamping force applied by the clamping ring 404, firmly locks the connecting pipe 3 onto the diversion port 2. This double fixing structure effectively resists the water pressure impact and external drag force commonly seen in garden irrigation, preventing the connecting pipe 3 from loosening or falling off.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
