Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, specifically a pressure-type compact connector. Background Technology

[0002] As a type of pipe connection device, connectors are used in various pipe connection fields such as water pipes, gas pipes, and heating pipes due to their excellent pipe connection tightness.

[0003] However, some existing connectors have defects in the tightness of their component connections, which can cause certain components inside the connector to loosen during use. This can affect the component's ability to fix the pipe, causing the pipe to come out of the connector or leakage to occur at the edge of the connector.

[0004] Some connectors employ complex structures to ensure good internal connection tightness. However, the high manufacturing cost and long manufacturing time of these connectors prevent mass production and hinder their widespread adoption in daily life. Furthermore, the process of inserting pipes into connectors becomes complicated and difficult, making it hard for non-professionals to complete the pipe connection in the presence of others. When connecting connectors to other pipe connection devices or pipes, their complex structure also affects the ease of operation for external connections. Utility Model Content

[0005] To address the technical deficiencies in the background technology, this utility model proposes a pressure-type compact connector, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0006] This utility model discloses a pressure-type compact connector, which includes a housing. At least one end of the housing has a quick-connect port in the axial direction. A sealing groove is provided in the middle of the housing, and a sealing element is fitted in the sealing groove. A positioning end cap is fitted in the quick-connect port.

[0008] As a further embodiment of the present invention, the end face of the housing near the quick-connect port is chamfered, and the side wall of the positioning end cover is provided with at least two first notches. The first notches extend from the middle of the positioning end cover to the end of the positioning end cover away from the first protruding edge, and make the arrangement of the first protrusion on the outer wall of the positioning end cover discontinuous.

[0009] As a further embodiment of the present invention, the outer wall of the unlocking member is provided with a second protrusion with a wedge-shaped cross-section, and the inner wall of the positioning end cover is provided with a second groove.

[0024] This utility model discloses a pressure-type compact connector, such as... Figure 1 and Figure 2 As shown, the connector includes a housing 1, at least one end of which has a quick-connect port 11 in the axial direction. A sealing groove 12 is provided in the middle of the housing 1, and a sealing element 16 is fitted in the sealing groove 12. A positioning end cap 2 is fitted in the quick-connect port 11. A locking ring 3 is provided at the quick-connect port 11 near the sealing groove 12 and is pressed into the housing 1 by the positioning end cap 2. An unlocking element 4 is fitted in the positioning end cap 2 to release the locking ring 3 from locking the pipe. A connecting part 13 is provided at the axial end of the housing 1 other than the quick-connect port 11.

[0025] It should be noted that when using this connector, it can be connected to other external pipe connection devices or pipes first, with the connecting part 13 as the connection point, and then the pipe can be inserted into the quick-connect port 11. After the pipe is fixed by the clamping ring 3, the pipe installation operation of the connector is completed. Alternatively, the pipe can be inserted into the quick-connect port 11, and the clamping ring 3 can fix the pipe to the quick-connect port 11 of the connector before connecting to the outside through the connecting part 13. The external connection method of the connector is diverse. When it is necessary to remove the pipe from the connector, the clamping ring 3 can be squeezed by pressing the unlocking part 4 to release the clamping ring 3 from the pipe, thereby unlocking the pipe inside the connector and pulling the pipe out of the quick-connect port 11. The pipe installation and removal operation on the connector and the connection of the connector to other pipe connection devices or pipes are convenient. The connection of each component is compact, ensuring the pipe connection effect. The structure and assembly operation of the connector are simple, reducing the manufacturing cost of the connector and meeting the needs of large-scale connector production.

[0026] It needs to be further explained that, such as Figures 2-4 As shown, the outer wall of the positioning end cover 2 is provided with a first protrusion 21 with a wedge-shaped cross-section, and the inner wall of the housing 1 outside the quick-connect port 11 is provided with a first groove 14 with the same cross-sectional shape as the first protrusion 21. One end of the positioning end cover 2 is provided with a first protruding edge 22 extending radially along the positioning end cover 2. The positioning end cover 2 is connected to the housing 1 by fitting the end of the housing 1 near the quick-connect port 11 between the first protrusion 21 and the first protruding edge 22, and the first protrusion 21 is fitted into the first groove 14.

[0027] When assembling the positioning end cover 2 to the quick-connect port 11 of the housing 1, the positioning end cover 2 is inserted along the axial direction of the connector. During the insertion process, the positioning end cover 2 can move more smoothly in the quick-connect port 11 by the guidance of the first protrusion 21. After the first protrusion 21 enters the first groove 14, the end of the housing 1 near the quick-connect port 11 will fit between the first protruding edge 22 and the first protrusion 21. The positioning end cover 2 can connect with the housing 1 by means of the groove-like structure formed by the first protruding edge 22 and the first protrusion 21, thereby realizing the assembly of the positioning end cover 2. The assembly operation of the positioning end cover 2 is simple.

[0028] Specifically, such as Figures 2-4 As shown, the end face of the housing 1 near the quick-connect port 11 is provided with a chamfer 15, and the side wall of the positioning end cover 2 is provided with at least two first notches 23. The first notches 23 extend from the middle of the positioning end cover 2 to the end of the positioning end cover 2 away from the first protrusion 22, and make the arrangement of the first protrusion 21 on the outer wall of the positioning end cover 2 discontinuous.

[0029] When the positioning end cover 2 is installed into the quick-connect port 11 along the axial direction of the connector, the first protrusion 21 slides obliquely on the chamfer 15 to form a guide, thereby making the alignment of the positioning end cover 2 at the port of the housing 1 near the quick-connect port 11 more accurate, and thus making the operation of the positioning end cover 2 entering the quick-connect port 11 smoother; while the setting of the first notch 23 allows the positioning end cover 2 to deform when it enters from the port of the housing 1 near the quick-connect port 11, making it easier for the first protrusion 21 to slide obliquely on the chamfer 15, and easier to enter the quick-connect port 11 after deformation, making the assembly operation of the positioning end cover 2 simpler.

[0030] It needs to be further explained that, such as Figure 2 , Figure 3 and Figure 5 As shown, the outer wall of the unlocking member 4 is provided with a second protrusion 41 with a wedge-shaped cross-section, and the inner wall of the positioning end cover 2 is provided with a second groove 24. The unlocking member 4 is movably connected to the second groove 24 through the second protrusion 41 to achieve connection with the positioning end cover 2. One end of the unlocking member 4 is provided with a second protruding edge 42 extending radially along the unlocking member 4, and the end of the unlocking member 4 away from the second protruding edge 42 abuts against the locking ring 3.

[0031] When the unlocking component 4 is assembled into the positioning end cover 2, the unlocking component 4 is inserted along the axial direction of the positioning end cover 2. During the insertion process, the second protrusion 41 guides the unlocking component 4 to enter the positioning end cover 2 more easily. After the second protrusion 41 enters the second groove 24, one end of the unlocking component 4 engages with the space of the positioning end cover 2 inside the second groove 24, and one end of the unlocking component 4 abuts against the locking ring 3. With the second groove 24 limiting the second protrusion 41, the movement of the unlocking component 4 within the positioning end cover 2 is restricted, thereby realizing the assembly of the unlocking component 4. The assembly of the unlocking component 4 is also simple to operate. The second protruding edge 42 can extend the end of the unlocking component 4, so that the end of the unlocking component 4 has a larger contact area for people to push the unlocking component 4 to move along the axial direction of the positioning end cover 2.

[0032] Specifically, such as Figure 3 and Figure 5 As shown, the surfaces of the through-hole ports in the middle of the unlocking component 4 and the positioning end cap 2 are respectively provided with a first rounded corner 43 and a second rounded corner 25.

[0033] When the unlocking component 4 is inserted into the positioning end cover 2 along the axial direction of the positioning end cover 2, the second protruding edge 42 slides obliquely on the second rounded corner 25 to form a guide, thereby making the alignment of the unlocking component 4 at the port of the positioning end cover 2 more accurate, and thus making the operation of the unlocking component 4 entering the positioning end cover 2 smoother; while the setting of the first rounded corner 43 makes the alignment operation of the pipe when entering the unlocking component 4 from the port of the unlocking component 4 easier, making it easier for the pipe to enter the unlocking component 4.

[0034] More specifically, such as Figure 2 and Figure 6 As shown, the middle part of the clamping ring 3 has several circumferentially arranged steel claws 31, which are inclined relative to the central axis of the clamping ring. The outer edge of the clamping ring 3 is provided with several second notches 32. The cross-sectional shape of the end of the unlocking member 4 away from the second protruding edge 42 is wedge-shaped.

[0035] When the unlocking member 4 moves along the axial direction of the positioning end cap 2, the end of the unlocking member 4 away from the second protruding edge 42 contacts the steel claw 31. The shape of this end allows the steel claw 31 to swing outward better, so that it no longer squeezes the outer wall of the pipe, thereby unlocking the pipe. The setting of the second notch 32 can make the clamping ring 3 itself have better toughness, avoiding the situation of the outer edge of the clamping ring 3 breaking.

[0036] It needs to be further explained that, such as Figure 2 As shown, the end face of the outer edge of the clamping ring 3 and the end face of the positioning end cover 2 pressed against the end of the clamping ring 3 are not parallel to each other.

[0037] When the outer edge of the clamping ring 3 is pressed by the end of the positioning end cap 2, the middle part of the clamping ring 3 will form a raised state on the axis of the connector, so that the inner position of the clamping ring 3 clamping the pipe can be closed as much as possible in the natural state, thus strengthening the clamping effect on the pipe and improving the fixing effect of the pipe.

[0038] It needs to be further explained that, such as Figure 7 As shown, the projection of the portion of the housing 1 other than the connecting part 13 onto a plane perpendicular to the axis of the housing 1 is a polygon.

[0039] The shape of the housing 1, excluding the connecting part 13, is designed to facilitate tool use, allowing for easy connection of the connector by pulling it with a tool during installation.

[0040] More specifically, such as Figure 1 and Figure 2 As shown, the connecting part 13 has an external thread 131, and the side walls of the axial ends of the housing 1, except for the quick-connect port 11, are all provided with external threads 131.

[0041] When the connecting part 13 has an external thread 131, it can be fitted to the part of the housing 1 other than the connecting part 13 by using a tool. Then, the connector can be rotated by pulling the entire connector with the tool. Then, it can be connected to other pipe connectors with internal threads or pipes with internal threads by using the external thread 131. The external connection operation of the connector is simple.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
