DETAILED DESCRIPTION

[0020] The utility model will be further explained in detail in combination with the drawings.

[0021] Please combine with reference to Figures 1 to 6 In order to achieve the above object, the utility model provides the following technical scheme:

[0022] A connecting piece for quick disassembly and assembly of water pipe, including water pipe joint 1, wherein water pipe joint 1 two ends are equipped with first connecting pipe sleeve 2 and second connecting pipe sleeve 3 respectively, wherein first connecting pipe sleeve 2 and second connecting pipe sleeve 3 are detachably connected with water pipe joint 1 respectively;Water pipe joint 1 is symmetrically provided with guide groove 4 in the inner wall close to first connecting pipe sleeve 2 one end, wherein first connecting pipe sleeve 2 outer wall front end is symmetrically provided with spring positioning bead 5, and spring positioning bead 5 is arranged in guide groove 4;Water pipe joint 1 is symmetrically provided with movable hole 6 close to second connecting pipe sleeve 3 one end, wherein each movable hole 6 outer wall is equipped with support seat 7;Support seat 7 is communicated with movable hole 6 in the middle, wherein support seat 7 is equipped with movable arm 8, and movable arm 8 penetrates movable hole 6 and abuts with second connecting pipe sleeve 3 outer wall.

[0023] The water pipe joint 1 is symmetrically provided with a guide groove 4 near the inner wall of one end of the first connecting pipe sleeve 2, which provides a sliding path for the spring positioning bead 5 and ensures the correct guidance of the first connecting pipe sleeve 2 during insertion; the outer wall of the front end of the first connecting pipe sleeve 2 is symmetrically provided with a spring positioning bead 5, which is designed to slide in the guide groove 4 and automatically snap into the positioning clamping groove 9 when reaching the end of the guide groove 4, thereby achieving stable connection; when the first connecting pipe sleeve 2 is inserted into the water pipe joint 1, the spring positioning bead 5 will slide along the guide groove 4, and as the insertion depth increases, the spring positioning bead 5 will be guided by the guide groove 4 until it reaches the predetermined position, thereby locking the position of the first connecting pipe sleeve 2; the water pipe joint 1 is symmetrically provided with a movable hole 6 near one end of the second connecting pipe sleeve 3, and each movable hole 6 is provided with a support seat 7, which provides space for the installation and movement of the movable arm 8; the support seat 7 is provided with a movable arm 8, which can penetrate the movable hole 6 and abut against the outer wall of the second connecting pipe sleeve 3; the design of the movable arm 8 allows it to move freely in the support seat 7 to adapt to the insertion and removal process of the second connecting pipe sleeve 3; when the second connecting pipe sleeve 3 is inserted into the water pipe joint 1, the movable arm 8 will contact the outer wall thereof, and as the insertion continues, the movable arm 8 will be pushed until the second connecting pipe sleeve 3 reaches the predetermined position; at this time, the positioning clamping head 11 on the movable arm 8 is locked in the positioning groove 12 on the second connecting pipe sleeve 3, thereby achieving stable connection.

[0024] Please refer to Figure 2 , Figure 3 and Figure 4 as an embodiment of the present application, the guide groove 4 is inclined along the length direction of the water pipe joint 1, and the spring positioning bead 5 is arranged in the guide groove 4 and moves along the inclined direction thereof.

[0025] In the above-mentioned scheme, the guide groove 4 is an important component inside the water pipe joint 1, and its design purpose is to provide a clear movement path for the spring positioning bead 5. The guide groove 4 is inclined along the length direction of the water pipe joint 1, which means that it is not straight but has a certain inclination angle. The inclination angle of the guide groove 4 can guide the spring positioning bead 5 to move along a specific path during insertion. This ensures that the first connecting pipe sleeve 2 can be correctly aligned with the water pipe joint 1 and smoothly inserted. As the first connecting pipe sleeve 2 is deeply inserted, the spring positioning bead 5 will move along the inclined direction of the guide groove 4. When they reach the positioning clamping groove 9 at the end of the guide groove 4, the spring positioning bead 5 will automatically be clamped into it, achieving stable connection between the first connecting pipe sleeve 2 and the water pipe joint 1. The spring positioning bead 5 is arranged in the guide groove 4 and can move along its inclined direction. This movement mechanism is realized based on the elasticity of the spring inside the spring positioning bead 5 and the guiding action of the guide groove 4. The spring inside the spring positioning bead 5 provides the necessary elastic force, allowing the positioning bead to move freely in the guide groove 4 and automatically clamp in when reaching the predetermined position. When the first connecting pipe sleeve 2 is inserted into the water pipe joint 1, the spring positioning bead 5 will be guided by the guide groove 4 and move along its inclined direction. During this process, the spring positioning bead 5 may go through stages of compression, stretching, and positioning until it is clamped into the positioning clamping groove 9. As the spring positioning bead 5 moves along the inclined direction of the guide groove 4 and is clamped into the positioning clamping groove 9, the connection between the first connecting pipe sleeve 2 and the water pipe joint 1 is achieved. This connection is stable because the elastic force of the spring positioning bead 5 and the constraint of the positioning clamping groove 9 work together to prevent accidental detachment of the connecting pipe sleeve. The design of the guide groove 4 inclined along the length direction of the water pipe joint 1 achieves quick, stable, and convenient water pipe connection through guiding, positioning, and locking functions. This design not only improves the reliability and durability of the connecting piece but also reduces the difficulty and cost of operation.

[0026] Please refer to Figure 3 , Figure 4 , as an embodiment of the present application, the guide groove 4 is provided with a positioning clamping groove 9 at the end, wherein the depth of the positioning clamping groove 9 is greater than the depth of the guide groove 4, and the positioning clamping groove 9 is matched with the spring positioning bead 5.

[0027] The main purpose of the positioning slot 9 is to achieve stable locking of the spring positioning bead 5. By providing a deeper slot than the guide slot 4, the positioning slot 9 can ensure that the spring positioning bead 5 can be automatically locked in when it reaches the predetermined position, and can be kept in place, thereby achieving firm connection of the connecting sleeve and the water pipe joint 1. The depth of the positioning slot 9 is greater than the depth of the guide slot 4, so as to ensure that the spring positioning bead 5 has enough space for stable locking when it is locked in. The deeper slot can provide stronger restraint force to prevent the spring positioning bead 5 from accidentally falling off due to external factors such as vibration, water pressure, etc. The shape of the positioning slot 9 is adapted to the spring positioning bead 5, which means that the opening, width and depth of the slot are designed according to the size and shape of the spring positioning bead 5. This adaptability ensures that the spring positioning bead 5 can be smoothly locked in the slot and form a good locking effect.

[0028] When the first connecting sleeve 2 is inserted into the water pipe joint 1, the spring positioning bead 5 will move along the inclined direction of the guide slot 4. As the insertion depth increases, the spring positioning bead 5 will gradually approach the positioning slot 9. When the spring positioning bead 5 reaches the opening of the slot, it will be automatically locked in the slot due to the spring force inside. At this time, the spring force of the spring positioning bead 5 and the restraint force of the slot work together to firmly lock the connecting sleeve on the water pipe joint 1. Through the adaptive design of the positioning slot 9 and the spring positioning bead 5, the connection between the connecting sleeve and the water pipe joint 1 becomes more stable and reliable. This design not only improves the vibration resistance and water pressure resistance of the connection, but also reduces the safety hazards caused by loose or falling connection. This design not only improves the performance and quality of the connecting piece, but also brings better user experience.

[0029] Please refer to Figure 2 As an embodiment of the present application, the first connecting sleeve 2 has a first sealing ring 10 on the outer wall of the top end, and the first sealing ring 10 abuts against the inner wall of the water pipe joint 1.

[0030] The main design purpose of the first sealing ring 10 is to form a tight sealing interface between the water pipe joint 1 and the first connecting sleeve 2 to prevent water or other fluids from leaking from the connection. This sealing function is crucial to ensure the integrity and performance of the water pipe system, especially in applications that require high pressure or high flow rate. The first sealing ring 10 is usually made of elastic materials such as rubber, silicone or polyurethane, which have good elasticity and wear resistance and can maintain their sealing performance for a long time. The size of the sealing ring is precisely designed to fit tightly with the inner wall of the water pipe joint 1. This adaptability ensures that the sealing ring can deform uniformly when subjected to pressure, thereby effectively filling any small gaps or irregular surfaces.

[0031] Please refer toFigure 3 、 Figure 4 and Figure 5 As an embodiment of the utility model, the movable arm 8 is provided with a positioning chuck 11 at one end close to the movable hole 6, wherein the positioning chuck 11 penetrates through the movable hole 6 and extends into the inner cavity of the water pipe joint 1, and the top end of the positioning chuck 11 is in an arc structure.

[0032] In the above scheme, the positioning chuck 11 is designed at one end of the movable arm 8 close to the movable hole 6, and its main purpose is to provide a reliable locking mechanism when the second connecting pipe sleeve 3 is connected with the water pipe joint 1; through the arc structure of the positioning chuck 11 and its extension in the inner cavity of the water pipe joint 1, it can effectively be clamped into the positioning groove 12 on the second connecting pipe sleeve 3, thereby realizing stable connection; the top end of the positioning chuck 11 is in an arc structure, which makes it easier to adapt to the curvature of the outer wall of the second connecting pipe sleeve 3 and provides smooth transition when clamped into the positioning groove 12; the arc structure also helps to reduce friction and resistance generated during connection and disassembly; the positioning chuck 11 is designed to be able to penetrate through the movable hole 6 and extend into the inner cavity of the water pipe joint 1, and this extension ensures that the positioning chuck 11 can be in full contact with the positioning groove 12 on the second connecting pipe sleeve 3 and provide sufficient locking force; the positioning chuck 11 is usually made of materials with certain elasticity and strength, such as metal or plastic, and this material selection ensures that the positioning chuck 11 can maintain its shape and performance during long-term use, while being able to withstand the stress and friction generated during connection and disassembly.

[0033] When the second connecting pipe sleeve 3 is inserted into the water pipe joint 1, first rotate the movable arm 8 to drive the positioning chuck 11 to rotate away from the movable hole 6, and as the insertion continues, when the top end of the second connecting pipe sleeve 3 abuts against the inner wall of the water pipe joint 1; reverse rotate the movable arm 8, so that the positioning chuck 11 rotates into the movable hole 6 and abuts against the positioning groove 12 opened on the second connecting pipe sleeve, and once the positioning chuck 11 is completely clamped into the positioning groove 12, it will be tightly locked on the second connecting pipe sleeve 3, and this locking mechanism ensures the stable connection between the connecting pipe sleeve and the water pipe joint 1, preventing the connection from loosening or falling off due to external factors such as vibration and water pressure.

[0034] Please refer to Figure 6 As an embodiment of the utility model, the outer wall of the second connecting pipe sleeve 3 is provided with a positioning groove 12, wherein the positioning groove 12 is matched with the positioning chuck 11.

[0035] In the above-mentioned scheme, the positioning groove 12 is designed on the outer wall of the second connecting pipe sleeve 3, and its main purpose is to form a perfect cooperation with the positioning clamp 11 on the movable arm 8. This cooperation mechanism aims to ensure that the second connecting pipe sleeve 3 can be accurately inserted into the water pipe joint 1 and achieve stable locking after insertion, thereby preventing the connection from loosening or falling off due to external factors such as vibration and water pressure. The shape and size of the positioning groove 12 are accurately designed to match the positioning clamp 11, and this adaptability ensures that the positioning clamp 11 can easily slide into the groove and automatically lock when it reaches the predetermined position. Through the cooperation mechanism of the positioning clamp 11 and the positioning groove 12, the connection between the second connecting pipe sleeve 3 and the water pipe joint 1 becomes more stable and reliable. This design not only improves the anti-vibration and water pressure resistance of the connection, but also reduces the safety hazards caused by loose or falling connections.

[0036] Please refer to Figure 4 , Figure 5 , as an embodiment of the present utility model, the movable arm 8 is provided with a pin hole 13 at one end close to the positioning clamp 11, wherein a pin shaft 14 is arranged in the pin hole 13, and the two ends of the pin shaft 14 are fixedly connected with the support seat 7.

[0037] In the above-mentioned scheme, the pin hole 13 is designed at one end of the movable arm 8 close to the positioning clamp 11, and the pin shaft 14 is arranged inside and fixedly connected with the support seat 7. The main purpose of this design is to provide a stable support and rotation axis for the movable arm 8, ensuring that the movable arm 8 can freely rotate within a certain range while maintaining the stability and reliability of its structure. Through the cooperation of the pin hole 13, the pin shaft 14 and the support seat 7, the movable arm 8 can freely rotate within a certain range.
