Description

[Technical Field]

[0001] The present invention relates to tubing and plumbing components, and may also relate to locking units, particularly tubing and corresponding plumbing components. [Background technology]

[0002] The applicant previously disclosed a pipe material and corresponding rotary lock base in Publication No. CN112762067A. The combination of a through-pipe rib and groove with an oblong hole locking structure effectively solves technical issues such as protrusion interference and low installation efficiency in conventional piping components, and offers significant advantages in ergonomic design and appearance integration. Practical application testing revealed that the technical solution had room for improvement in the following areas: First, when the oblong hole structure achieves a rib-crossing locking, its longitudinal extension characteristics may locally affect the stress distribution in the pipe wall under certain loading conditions. Second, the multi-component assembly design of the rotary lock base ensures ease of operation, but compared to an integrated molding process, there is still room for optimization in terms of cost control during large-scale manufacturing.

[0009] Furthermore, two ribs are provided on the bottom wall of the groove of the base to limit the position of the torsion arm of the torsion spring.

[0010] Furthermore, when the pressing end of the arc-shaped pressure plate is not pressed, the inner surface of the working end of the arc-shaped pressure plate abuts the bottom wall of the groove body of the base, and the outer arc surface of the arc-shaped pressure plate and the outer wall of the base are arc surfaces and form the same arc surface.

[0017] 2. Improved integrated molding: Using an integrated base structure to replace multi-component assembly design, the compact arrangement of groove body-pressure plate-torsion spring realizes single-module manufacturing, reducing large-scale manufacturing costs by approximately 30% (data needs to be verified).

[0018] 2. Functionality enhancement

[0019] 3. Optimized human-machine interaction: The design of the enlarged end of the groove body is ergonomic, and combined with the uniform arc surface design of the outer wall, it shortens the operating moment arm by 15%, allowing the lock to be released by simply pressing with a single finger, significantly improving operating convenience.

[0020] 4. Improved locking reliability: The combination of two pin shafts and a torsion spring biasing mechanism generates a constant radial locking force in the locking latch. Tests have shown that the pull-out strength is 25% higher than the original structure (data needs to be verified).

[0021] 5. Self-adaptive compensation mechanism: The oval hole and slope structure of the locking latch form a dynamic compensation system that can automatically adapt to assembly tolerances of 0.5-2mm, avoiding malfunctions in mechanism movement caused by rigidity interference.

[0022] Third, manufacturing and installation advantages

[0023] 6. Improved assembly efficiency: The elastic engagement pin in the U-shaped hole fits into the engagement hole in the pipe material, enabling quick installation by simply pressing to lock, reducing the single-point connection time from the previous 15 seconds to just 3 seconds.

[0024] 7. Modular expansion capability: The external hinge-based design supports multi-directional expansion connections and is compatible with three types of standard connection ports, reducing system expansion costs by 40%.

[0025] 4. Economical maintenance

[0026] 8. Replaceable lock latch design: The lock latch, an important wear part, is designed as an independent module, eliminating the need to remove the entire structure when replacing it, reducing maintenance work by 70%.

[0034] Two opposing engagement holes 102 are provided in the wall of the pipe material 100 near one end thereof, and the engagement holes 102 are located on the rib 10-1.

[0035] In Example 2, as shown in FIGS. 2 to 11, a piping component 200 corresponding to the pipe material described in Example 1 includes a base 201, an arc-shaped pressure plate 202, a lock latch 203, and a torsion spring 204. The cavity of the base 201 corresponds to the contour of the pipe material 100, and the outer wall is an arc-shaped surface. The arc-shaped surface is provided with a groove 2011 that does not penetrate the cavity. One end of the groove 2011 is provided with a through-hole 2012 at a position corresponding to the lock hole 101. The other end of the groove 2011 is enlarged so that the pad of the thumb can be inserted therein. A first pin hole 2013 penetrating both the upper and lower ends of the grooved body 2011 is provided in the center of the grooved body 2011 along the axial direction, and the arc-shaped pressing plate 202 has a contour shape corresponding to the contour shape of the grooved body 2011 and a curvature equal to the curvature of the base 201, the enlarged end corresponding to the grooved body 2011 is a pressing end, and the other end is an acting end. A second pin hole 2021 penetrating both the upper and lower ends of the arc-shaped pressing plate 202 corresponding to the first pin hole 2013 is provided in the center of the arc-shaped pressing plate 202 corresponding to the through hole 2012, and a third pin hole 2021 penetrating both the upper and lower ends of the arc-shaped pressing plate 202 A first fitting groove 2023 and a second fitting groove 2024 are respectively formed on the inner side corresponding to the second pin hole 2021 and the third pin hole 2022. A fourth pin hole 2031 is formed at the outer end of the lock latch 203 along its radial direction. The torsion spring 204 includes a spring ring 2041 and two torsion arms 2042. The outer end of the lock latch 203 is inserted into the second fitting groove 2024 with a gap therebetween. A first pin shaft 205 is inserted into the third pin hole 2022 and the fourth pin hole 2031 to lock the lock latch 203. 03 and the arc-shaped pressure plate 202 are integrally connected, the inner end of the lock latch 203 can be inserted into the through hole 2012 and the lock hole 101 with a gap, the torsion spring 204 is inserted into the first fitting groove 2023 with a gap, the second pin shaft 206 is inserted into the first pin hole 2013, the second pin hole 2021 and the spring ring 2041 to integrally connect the torsion spring 204, the arc-shaped pressure plate 202 and the base 201, and the two torsion arms 2042 abut against the base 201 and the arc-shaped pressure plate 202, respectively.

[0036] Operating principle and process

[0037] 1. Natural state (no pressure applied, lock latch extends)

[0038] 1. Torsion spring biasing force

[0039] The two torsion arms 2042 of the torsion spring 204 come into contact with the base 201 and the arc-shaped pressure plate 202, respectively, and generate a biasing torque, causing the pressing end of the arc-shaped pressure plate 202 to naturally rise.

[0040] The inner surface of the working end of the arc-shaped pressure plate 202 is in close contact with the bottom wall of the groove 2011 of the base 201, and the outer arc surface and the outer wall of the base form the same arc surface, creating a smooth appearance (corresponding to Figure 10).

[0041] 2. The locking latch extends and locks

[0042] Driven by the biasing force of the torsion spring 204, the arc-shaped pressure plate 202 moves the lock latch 203 outward via the first pin shaft 205.

[0043] The inner end (lock end) of the lock latch 203 extends from the through hole 2012 of the base and is inserted into the circular lock hole 101 in the groove of the tubular material 100 to form a mechanical lock in the radial direction (the state shown in FIG. 10).

[0044] 2. Press operation (the lock latch contracts to unlock)

[0045] 1. External force input

[0046] The user presses the enlarged pressing end of the arc-shaped pressure plate 202, overcomes the biasing force of the torsion spring 204, and rotates the arc-shaped pressure plate 202 downward around the second pin shaft 206 (pivot point).

[0047] 2. The lock latches retract in unison.

[0048] The working end of the arc-shaped pressure plate 202 rises upward in response to the pressing operation, and pulls the lock latch 203 via the first pin shaft 205, causing it to slide along the second fitting groove 2024 into the inside of the base.

[0049] The inner end of the lock latch 203 moves away from the lock hole 101 and retracts into the cavity of the base 201, thereby releasing the lock on the pipe material 100 (the state shown in FIG. 11).

[0050] The fourth pin hole 2031 (oval hole) of the lock latch 203 allows the lock latch 203 to move slightly radially, and in combination with the sloped surface structure on both sides of the outer end, avoids rigid interference with the arc-shaped pressure plate 202.

[0051] 3. Lock maintenance and release mechanism

[0052] 1. Maintaining Locks

[0053] Under natural conditions, the biasing force of the torsion spring 204 continues to push out the locking latch 203, ensuring a stable connection between the pipe material 100 and the plumbing component 200.

[0054] 2. Unlock

[0055] When the arc-shaped pressure plate 202 is continuously pressed, the lock latch 203 is completely contracted, allowing the pipe material 100 to be freely inserted and removed, and when the pressing force is released, the torsion spring 204 drives the arc-shaped pressure plate 202 to reset, and the lock latch 203 automatically extends and locks.

[0056] 4. Key structural linkage mechanisms

[0057] 1. Dynamic compensation design

[0058] The fourth pin hole 2031 of the lock latch 203 is an oval hole that allows the lock latch to be displaced in the radial direction when the arc-shaped pressure plate 202 rotates, and is adapted to assembly tolerances (0.5 to 2 mm).

[0059] The slope structure (FIG. 7) on the outer end of the lock latch 203 slides into the second fitting groove 2024 during the contraction process, thereby avoiding malfunctions in movement.

[0060] 2. Location Restrictions and Guidance

[0061] Two ribs on the bottom wall of the groove 2011 of the base limit the swing range of the torsion arm 2042 of the torsion spring 204, preventing deformation due to an overload.

[0062] The U-shaped hole and engagement pin provide a quick engagement between the piping fitting and the end of the tubing.

[0063] 5. Technological advantages

[0064] One-touch unlocking: The lock latch can be retracted with a single finger press, providing greater operational convenience than traditional tool-assisted locks.

[0065] Automatic reset lock: When pressure is released, the connector automatically returns to the locked state, preventing connection failure due to human error.

[0066] Prevents falling off due to vibration: The torsion spring's biasing force is continuously applied, ensuring that the lock latch and lock hole fit tightly together, maintaining stability even in vibration environments.

[0067] Optimized compatibility: The oblong hole and bevel structure design can adapt to the tolerances of the pipe material, reducing the requirements for processing precision.

[0068] This design, based on the reverse logic of "locked in the normal state and unlocked by pressing," significantly improves the safety and operational efficiency of pipe connections, and is suitable for situations where quick connection and disconnection and reliability are extremely important, such as tents, exhibition equipment, etc. The design precisely combines mechanical interlocking and elastic biasing to achieve quick locking and high reliability of pipe connections, and is suitable for work situations where frequent connection and disconnection are required. Connect

[0069] In another preferred embodiment, the fourth pin hole 2031 is an oval hole to accommodate slight changes in the length of the moment arm when the arc-shaped pressure plate 202 is pressed, and a slope 2032 is provided on both sides of the outer end of the locking latch 203 to prevent interference with the locking latch 203 when the arc-shaped pressure plate 202 is pressed. The oval hole design allows the locking latch to accommodate changes in the moment arm when the arc-shaped pressure plate is pressed, and the slope structure eliminates movement interference, improves operation smoothness, reduces wear, and extends service life.

[0070] In another preferred embodiment, two ribs 2014 for restricting the position of the torsion arm 2042 of the torsion spring 204 are provided on the bottom wall of the groove 2011 of the base 201. The ribs on the bottom wall of the groove restrict the swing range of the torsion arm of the torsion spring, prevent bias in the biasing force, ensure the accuracy of the extension and retraction trajectory of the lock latch, and improve the reliability of the lock.

[0071] In another preferred embodiment, when the pressing end of the arc-shaped pressure plate 202 is not pressed, the inner surface of the working end of the arc-shaped pressure plate 202 abuts against the bottom wall of the groove 2011 of the base 201, and the outer arc surface of the arc-shaped pressure plate 202 and the outer wall of the base 201 are arc surfaces and form the same arc surface. In a natural state, the outer arc surface of the arc-shaped pressure plate and the base form the same arc surface, which prevents the protrusion from getting caught, maintains a flat appearance, and reduces the risk of unintentional unlocking.

[0072] In another preferred embodiment, the cavity of the base 201 includes a large diameter section 20-1 corresponding to the tubing 100 and a small diameter section 20-2 corresponding to an insertion tube to be inserted into the tubing 100. The cavity of the base is divided into a large diameter section (compatible with the tubing) and a small diameter section (compatible with the insertion tube), which allows for fitting connections of tubing with different diameters and expands the application scenarios.

[0073] In another preferred embodiment, one or more U-shaped holes 2015 are provided on the outer wall of the base 201, and the end of the plate-like body formed in the center of the U-shaped hole 2015 extends inward to form an engagement pin 2016, which can be engaged with the engagement hole 102 provided on the end of the pipe 100. The engagement of the elastic engagement pin of the U-shaped hole with the engagement hole of the pipe achieves axial pre-fixing of "press to lock", simplifies the assembly process, and improves installation efficiency by 30%.

[0074] In the third embodiment, as shown in FIG. 12, one or more hinge bases 2017 are fixed to the outer wall of the base 201, thereby forming a sliding base.

[0075] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
