Description

Technical Field

[0001] The utility model relates to a push-type pipe joint locking structure, in particular to a push-type pipe joint locking structure which improves the smooth and accurate locking and unlocking actions of a pipeline quick joint. Background Art

[0002] In the current gas supply system or liquid cooling system, pipes and joints are usually used to connect the unit modules, and there is flowing gas or liquid inside the pipes. Generally, the water cooling system has a better heat dissipation effect, which can effectively increase the maximum operating power of electronic components and has been widely used in high-performance electronic components. Therefore, in order to meet the pipeline configuration requirements of various systems, the water cooling system will set up multiple fluid pipelines, and different fluid pipelines need to be frequently disconnected and connected during use and maintenance to meet the needs of cleaning, repair and maintenance.

[0003] See also Figure 1 , Figure 2 There is a fluid connector and a fluid connector element using the fluid connector, such as publication number CN109944995A, which includes a plug 10 and a socket 20. The plug 10 has a plug housing 11 and a stop step 15 located on the plug housing 11. The socket 20 has a socket housing 21 and a longitudinal mounting hole 211 provided on the socket housing 21. A locking member 25 can be assembled in the mounting hole 211 and guide the locking member 25 to move in the hole. The two ends of an elastic member 26 are respectively connected to the locking member 25 and the socket housing 21, and the locking member 25 has a locking channel 256 for one end of the plug 10 to pass through, and the lower side of the locking channel 256 is provided with a conical surface 253 that matches the stop step 15. Thus, when inserting, one end of the plug 10 enters the inner cavity of the socket housing 21 and enters the locking channel 256 of the locking member 25. After the blocking step 15 on the socket housing 21 and the tapered surface 253 on the locking member 25 are blocked and matched with each other, the plug 10 and the socket 20 are locked to prevent the plug 10 from coming out. When unlocking, the locking member 25 is pressed downward, and the locking member 25 is forced to move downward along the mounting hole 211 as a whole, until the tapered surface 253 of the locking member 25 leaves the blocking step 15 and makes the blocking step 15 pass over the tapered surface 253 to be disengaged from each other, even if the plug 10 and the socket 20 move relative to each other, the two are unlocked from each other.

[0004] However, the conventional structure has the following problems. That is, since the locking member 25 is a single-piece, integrated Γ-shaped member, mainly comprising a longitudinal insertion portion 251 and a transverse operating portion 252 integrally connected to one end of the longitudinal insertion portion 251, the longitudinal insertion portion 251 is used to be inserted into the mounting hole 211, and the transverse operating portion 252 is used for pressing and operating, and the elastic member 26 is arranged between the operating portion 252 and the socket housing 21, so that when the Γ-shaped locking member 25 is subjected to a force (such as: downward pressure or the resetting and pushing force of the elastic member 26), it moves downward or upward along the mounting hole 211 as a whole.

[0005] Therefore, it can be known that the position where the user applies force is the transverse operating portion 252 of the locking member 25. When the transverse operating portion 252 is pressed downward, since the transverse operating portion 252 is not the position where the force is applied to the insertion portion 251, the insertion portion 251 is not directly given a positive force to move. Therefore, when the free end of the transverse operating portion 252 is pressed downward, the longitudinal insertion portion 251 moves downward in the mounting hole 211 synchronously and relatively, and a longitudinal deflection occurs, resulting in the inner upper side wall 251a and the outer lower side wall 251b of the insertion portion 251 and the relative inner wall of the mounting hole 211 generating mutual friction and wear at specific positions or partial contact surfaces (for example, Figure 1 In addition, when the lateral operating portion 252 is not pressed downward, the elastic member 26 pushes the lateral operating portion 252 upward due to elastic reset. Since the lateral operating portion 252 is pushed upward by the elastic member 26 near the free end, the longitudinal insertion portion 251 located on one side of the lateral operating portion 252 is synchronously moved upward, and a longitudinal deflection occurs, resulting in the outer upper side wall 251c and the inner lower side wall 251d of the insertion portion 251 being aligned with the mounting hole 21. 1 produces mutual friction and wear at a specific position or part of the contact surface relative to the inner wall; therefore, in the above-mentioned cases, serious interference will occur and resistance will be generated, which will inevitably greatly affect the overall movement of the Γ-shaped locking member 25 and cause problems such as extremely unsmooth movement. When the longitudinal insertion portion 251 continues to deviate, it will cause the longitudinal insertion portion 251 to be worn, bent or broken for a long time, or the action of moving down to unlock or moving up to stop is improper, which will easily cause excessive wear and damage to both the socket housing 21 and the locking member 25. Therefore, the above-mentioned conventional defects are the primary problems to be solved by the present utility model. Utility Model Content

DETAILED DESCRIPTION

[0029] The above-mentioned purpose and the structural and functional characteristics of the present invention will be described in detail according to the preferred embodiments of the accompanying drawings. However, the accompanying drawings are only provided for reference and description and are not intended to limit the present invention.

[0030] See also Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown in the figure, the utility model is a push-type pipe joint locking structure 100, which is used to form a structural combination of a first pipe body 70 and a second pipe body 80 that can be quickly engaged or separated. A pivot structure is used as a pivot fulcrum, and a downward pressing force or an upward thrust force due to the elastic return of a spring is provided to achieve a smooth radial linkage stroke, so as to release or clamp the axial limit of a correspondingly connected pipe body (such as the second pipe body 80 in the embodiment of the utility model, including but not limited to it), so as to achieve the engagement or releasable connection of the first and second pipe bodies, thereby improving the overall connection reliability.

[0031] See also Figure 3 , Figure 4 As shown, the push-type pipe joint locking structure 100 comprises a connecting pipe body 30, a pressing member 40, a spring 50, a pressing buckle body 60, and at least two shafts T1 and T2.

[0032] The connecting tube body 30 has a first end 301 and a second end 302 with an axis extending in the front-to-back direction, and a receiving hole 31 and a groove 33 disposed between the first and second ends 301 and 302. The connecting tube body 30 is also provided with a passage 303 axially penetrating the first end 301 and the second end 302. The first end 301 allows the docking portion 81 of the second tube body 80 to slidably penetrate and be disposed in the passage 303, and the second end 302 can be sleeved on the outer edge of the connecting portion 71 of the first tube body 70. The receiving hole 31 is opened on the upper and lower tube walls of the connecting tube body 30 along the longitudinal (diameter) direction of the tube wall, and the receiving hole 31 is adjacent to the first end 301 and communicates with the passage 303. The groove 33 is recessed from the outside of the tube wall to the inside and is disposed between the accommodating hole 31 and the second end 302, and a pair of tube pivot holes 34 are disposed corresponding to the groove 33, and the two tube pivot holes 34 vertically penetrate two opposite groove sides 332 of the groove 33. An insertion hole 35 is disposed at the bottom of the groove 33, and the insertion hole 35 is recessed on the arc groove bottom A of the groove 33 and adjacent to the tube pivot hole 34.

[0033] Furthermore, the groove 33 is parallel to the axial direction of the connecting tube 30 and is composed of a front section 331a, a middle section 331b and a rear section 331c (eg Figure 4 As shown in FIG. 1 , in this embodiment, the concave depth of the middle section 331b is greater than the concave depth of the front section 331a and the rear section 331c, and the middle section 331b is connected to the bottom of the front section 331a and the rear section 331c to form a concave arc groove bottom A, and the front section 331a and the rear section 331c each have an opening facing the second tube body 80 and the first tube body 70 (as shown in FIG. Figure 5 , Figure 6 shown).

[0034] Also, see Figure 5 As shown, the inner wall of the connecting tube body 30 has an inner convex annular wall 304 protruding toward the center of the axis near the second end 302 , and the center of the inner convex annular wall 304 is formed to communicate with the channel 303 .

[0035] The pressing member 40 has a pressing side 41 at the top, a bottom side 42, a first pivoting portion 43, a second pivoting portion 44, and a receiving hole 45; the first pivoting portion 43 is vertically protruded at the front end of the bottom side 42, and the first pivoting portion 43 has a first pivoting hole 431 at the bottom end and a receiving notch 432 upwardly formed from the bottom end, and the first pivoting hole 431 can be pivotally matched with the pressing buckle body 60. The second pivoting portion 44 is vertically protruded at the bottom side 42 and adjacent to the first pivoting portion 43, and the second pivoting portion 44 has a second pivoting hole 441 at the bottom end, and the second pivoting hole 441 can be pivotally matched with the tube body pivoting hole 34 of the groove 33. The receiving hole 45 is recessed on the bottom side 42 and adjacent to the second pivoting portion 44.

[0036] Furthermore, the bottom end of the second pivoting portion 44 of the pressing member 40 is configured as an arc-shaped bottom side B to correspond to and cooperate with the arc-shaped groove bottom A of the groove 33. The pivoting structure ensures that the arc-shaped bottom side B of the second pivoting portion 44 will not interfere with the arc-shaped groove bottom A of the groove 33 when the second pivoting portion 44 is pivoted.

[0037] In addition, the width of the second pivot portion 44 of the pressing member 40 is smaller than the width between the two opposite groove sides 332 of the groove 33, so that the second pivot portion 44 can be inserted between the two opposite groove sides 332 of the groove 33 and pivotally connected to the tube body pivot holes 34, so as to facilitate the pressing member 40 to form a pivot fulcrum with the second pivot portion 44 relative to the tube body pivot hole 34 to perform stable pivoting movement.

[0038] The two ends of the spring 50 are respectively disposed in the insertion hole 35 at the groove 33 and the receiving hole 45 of the pressing member 40. Thus, the spring 50 is disposed between the connecting tube body 30 and the pressing member 40 and can provide the pressing member 40 with an elastically restoring upward thrust.

[0039] The push button body 60 has a top 61, an opening 62 and a clamping edge 621 adjacent to the opening 62. In this embodiment, the shape and size of the push button body 60 are smaller than or equal to the shape and size of the receiving hole 31, so that the push button body 60 can radially penetrate the receiving hole 31 and be disposed in the hole and can slide upward and downward (radially) in a certain direction. The top 61 is convexly disposed on the top of the push button body 60 and is provided with a button body pivot hole 611, which can be pivotally matched with the first pivot hole 431 of the pressing member 40. The diameter of the opening 62 is greater than or equal to the inner wall circumference of the channel 303 of the connecting tube body 30. The locking edge 621 is an inner locking edge formed by the inner edge of the opening 62 extending radially toward the center line of the opening, so that the opening 62 and the locking edge 621 can extend into or leave the channel 303 as the push button body 60 slides radially relative to the accommodating hole 31.

[0040] Specifically, the width of the top end 61 of the aforementioned push button body 60 is smaller than the width of the accommodating notch 432 on the bottom side of the first pivot portion 43, which facilitates the push button body 60 to be placed in the accommodating notch 432 with the top end 61 and pivotally cooperate with the first pivot hole 431.

[0041] The at least two shafts include a first shaft T1 passing through the first pivot hole 431 of the pressing member 40 and the buckle body pivot hole 611 of the pressing buckle body 60, and a second shaft T2 passing through the second pivot hole 441 of the pressing member 40 and the tube body pivot hole 34 of the connecting tube body 30, so that the pressing member 40 is pivoted on the pressing buckle body 60 and the connecting tube body 30 with the first pivot hole 431 and the second pivot hole 441 respectively.

[0042] Furthermore, a first valve core structure can be set in the inner cavity of the aforementioned first tube body 70, and a second valve core structure can be set in the inner cavity of the aforementioned second tube body 80. In order not to blur the focus of the creation and to cooperate with the push-type pipe joint locking structure 100 of the utility model, only the corresponding matching structures of the first and second tube bodies 70 and 80 are disclosed, including but not limited to.

[0043] The first tube body 70 has a connecting portion 71, a first connecting side 72, and a first flow channel 73 axially penetrating the first tube body 70. The connecting portion 71 and the first connecting side 72 are respectively arranged at two ends of the first tube body 70. An annular groove 74 is radially circumferentially recessed on the outer wall of the connecting portion 71.

[0044] The second tube body 80 has a docking portion 81, a second connecting side 82, a clamping groove 83, and a second flow channel 84 axially penetrating the second tube body 80; the docking portion 81 and the second connecting side 82 are respectively disposed at both ends of the second tube body 80; the clamping groove 83 is concavely disposed or surrounded by the outer edge of the middle section of the second tube body 80. A convex wall 85 with an inclined surface 851 is convexly disposed on the outer edge of the docking portion 81 of the second tube body 80 and adjacent to the clamping groove 83. The docking portion 81 of the second tube body 80 can be movably inserted axially into the connecting portion 71 of the first tube body 70.

[0045] See also Figure 5 , which is a combined cross-sectional view of the locking structure of the push-type pipe joint of the utility model and cooperates with Figure 4As shown; when used in plug-in assembly, first, the connecting portion 71 of the first tube body 70 is inserted into the second end 302 of the connecting tube body 30 and pressed against the inner convex annular wall 304, and the first flow channel 73 of the first tube body 70 is connected to the channel 303 of the connecting tube body 30, and a rotating component 9 can be set between the second end 302 and the connecting portion 71 to realize the axial anti-slip limit function of the first tube body 70 and the connecting tube body 30 (details are disclosed later). Secondly, since the spring 50 of the connecting tube body 30 elastically resets and pushes the pressing member 40 upward to present a horizontal state, the first pivoting portion 43 links the pressing buckle body 60 to be radially located inside the accommodating hole 31. At this time, the clamping edge 621 of the opening 62 protrudes from the channel 303 of the connecting tube body 30. When the second tube body 80 is inserted into the first end 301 of the connecting tube body 30 with the docking portion 81 and enters the channel 303, until the clamping edge 621 passes over the inclined surface 851 of the convex wall 85 of the second tube body 80 and then extends into the clamping groove 83 and is clamped, the The pressing buckle body 60 limits the axial position of the second tube body 80, so that the pressing type pipe joint locking structure 100 is in a locked position, so that the docking portion 81 of the second tube body 80 is connected to the connecting portion 71 of the first tube body 70, thereby firmly positioning the second tube body 80 and the first tube body 70 in a joined state. Since the convex wall 85 of the second tube body 80 has an inclined surface 851, the pressing buckle body 60 can be directly lifted by the inclined surface 851 when relatively inserted into the connecting tube body 30, and can be directly combined with the connecting tube body 30 without pressing the pressing member 40.

[0046] See also Figure 6 , which is a cross-sectional view of the press-type pipe joint locking structure of the utility model; during the press-unlock operation, the press side 41 of the press member 40 is pressed downward, and the bottom side 42 presses down the spring 50, and the press member 40 uses the second pivot hole 441 of the second pivot part 44 and the pipe body pivot hole 34 at the groove 33 of the connecting pipe body 30 as a fulcrum, and the arc bottom side B of the bottom end of the second pivot part 44 cooperates with the arc groove bottom A of the groove 33. The structural configuration makes the second pivot part 44 not to be in contact with the groove during the pivoting action. 33 produces interference phenomenon, and at the same time, when the first pivot portion 43 is lifted up, the push button body 60 is pulled up radially relative to the accommodating hole 31, so that the clamping edge 621 of the opening 62 leaves the clamping groove 83 and is higher than the convex wall 85, thereby releasing the axial limitation of the push button body 60 on the second tube body 80, constituting that the push-type pipe joint locking structure 100 is in an unlocked position, so that the docking portion 81 of the second tube body 80 can be pulled out through the opening 62 along the axial direction, even if the second tube body 80 is separated from the first tube body 70.

[0047] In addition, when the separated second tube body 80 needs to be re-inserted, the second tube body 80 only needs to apply an axial pushing force to the first end 301 of the connecting tube body 30 with the docking portion 81, so that the docking portion 81 enters the channel 303, and Figure 5 The axial movement shown is performed until the locking edge 621 is inserted into the locking groove 73, so that the push-type pipe joint locking structure 100 is in a locked position, and the purpose of the plug-in connection of the first pipe body 70, the connecting pipe body 30, and the second pipe body 80 can be completed, and there is no need to press the pressing member 40. In addition, when unlocking, the first pipe body 70 and the connecting pipe body 30 can be unlocked and disassembled by pressing the member 40 downward, thereby improving the overall connection reliability, and the overall operation process is simple, convenient and smooth.

[0048] As mentioned above, please refer to Figure 4 , Figure 5 The push-type pipe joint locking structure of the utility model shown in the figure, the rotating assembly 9 is arranged between the second end 302 of the connecting pipe body 30 and the connecting portion 71 of the first pipe body 70, which includes a pair of rod holes 90 on the inner wall of the second end 302 of the connecting pipe body 30 along the vertical radial direction of the pipe wall for penetrating a stopper 91. In this embodiment, the two rod holes 90 are arranged in two pairs, arranged in an upper and lower manner and passing through the pipe wall, so that the stopper rods 91 can be inserted into the rod holes 90 from the outside and fixed on the inner wall of the second end 302, and can cooperate with the annular groove 74 on the outer edge of the connecting portion 71 of the first pipe body 70; that is, the connecting pipe body 30 is connected to the second end 302 of the connecting pipe body 30. During the assembly process of being sleeved on the outer edge of the connecting portion 71 of the first tube body 70, the portion of the rod body of the blocking rod 91 located inside the connecting tube body 30 will be stuck in the annular groove 74, thereby realizing the axial anti-slip limit assembly function of the second end 302 of the connecting tube body 30 relative to the connecting portion 71 of the first tube body 70, and providing the second end 302 with a relative axial rotation adjustment function connected to the outer edge of the connecting portion 71, which can avoid the phenomenon of skewness and misalignment of the docking position of the connecting tube body 30 and the first tube body 70, and enable the pressing member 40 assembled on the connecting tube body 30 to maintain a shape above the connecting tube body 30, providing convenience and accuracy of operation. Even when the first connection side 72 of the first tube body 70 can be connected to a first tube connector P2, the second connection side 82 of the second connector 80 can be connected to a second tube connector (not shown in the figure). In this way, the problem of the asymmetry between the first tube body 70 and the second tube body 80 when they are respectively connected is solved.

[0049] Therefore, the utility model improves the conventional structure that generates a bending moment when pressed downward, which will cause the Γ-shaped locking member 25 structure to rub against the inner wall of the mounting hole 211, resulting in serious interference and wear problems, causing the overall movement process of the Γ-shaped locking member 25 to be extremely unsmooth, and unable to be unlocked or stopped smoothly, thereby affecting the conventional plug 10 and the socket 20. Incomplete engagement leads to problems such as water leakage.

[0050] The utility model has the following advantages by respectively setting the pressing member 40 to the connecting tube body 30 and the pressing buckle body 60 in a pivotal connection, and the pressing buckle body 60 is radially penetrated in the receiving hole 31 of the connecting tube body 30 and the opening 62 is used for the axial passage of one end of the second tube body 80, and the second pivoting portion 44 and the groove 33 are pivotally connected to form a fulcrum.

[0051] 1. The pivot point is used to allow the pressing piece to be evenly and stably lever-actuated, so as to achieve smooth radial movement of the pressing buckle body and avoid assembly errors.

[0052] 2. Avoid excessive friction between the buckle body and the receiving hole to cause wear.

[0053] 3. Allowing the connecting tube body to be used as an intermediate component between the first and second tube bodies avoids changing the original structure of the first and second tube bodies relative to the joint ends, thereby improving connection reliability and reducing costs.

[0054] 4. The push-type pipe joint locking structure is used to prevent the first pipe body and the second pipe body from rotating relative to each other, thereby preventing the first pipe connector P1 and the second pipe connector (not shown) from becoming asymmetric with each other.

[0055] 5. The first and second tube bodies are allowed to move radially without changing the central passage or flow channel.

[0056] The above description has been a detailed description of the utility model, and the above description is only a preferred embodiment of the utility model, which should not limit the scope of implementation of the utility model. That is, all equivalent changes and modifications made according to the utility model should still fall within the scope of the patent coverage of the utility model.
