Technical Field
[0001] The utility model relates to the field of pipe connectors for connecting soft and hard pipes, in particular to a simple and detachable soft and hard pipe connector. Background Art
[0002] The soft and hard tube connector is an important tool for realizing medium transfer transmission using hard tubes and soft tubes. It is also widely used in fields such as agricultural irrigation and gas transmission.
[0003] Since there are not many structural types of soft and hard pipe connectors, they are not common in the market and their production costs are relatively high, resulting in a relatively small market audience. The popularity of soft and hard pipe connectors is limited, and the market hopes to reduce the cost of soft and hard pipe connectors to increase their audience. Secondly, since most of the hard pipes or hoses connected to the soft and hard pipe connectors will have obvious scratches on the surface after being removed, the removed hard pipes or hoses cannot be re-installed into the soft and hard pipe connectors or reused on other pipe connectors, which is not conducive to the rational use of resources. In addition, since the hard pipe quick-plug end used at the drainage end of many indoor equipment on the market is very short, the bulky pipe connector cannot achieve pipe connection in this scenario. Utility Model Content
[0004] In view of the above technical deficiencies, the utility model provides a hard and soft pipe connector which can form a stable sealing connection effect for both hard pipes and soft pipes, can realize tool-free pipe installation and disassembly, has a simple and compact structure, is easy to assemble, has a low manufacturing cost, and the connected pipes can be reused.
[0005] In order to achieve the above object, the utility model is implemented through the following technical solutions:
[0006] The utility model discloses a simple and detachable soft and hard tube connector, which comprises a shell, a threaded end cover, a claw ring and a sealing member, wherein the two ends of the shell in the axial direction are respectively a hard tube quick-insertion end for inserting a hard tube and a hose connecting end for sleeved hose, the outer wall of the hard tube quick-insertion end away from the center of the shell is provided with an external thread section, the threaded end cover is detachably connected with the shell through the cooperation of the internal thread section and the external thread section provided on the inner wall, the inner wall of the shell close to the external thread section is provided with a circle of limiting grooves, the claw ring is a non-closed ring structure and has a "U"-shaped cross-section, the sealing member is arranged in a sealing cavity between the claw ring and the end of the threaded end cover away from the center of the shell, the sealing member is arranged in a sealing cavity between the claw ring and the threaded end cover, and the outer surface of the hose connecting end is provided with at least two circles of sealing bosses.
[0007] Furthermore, the middle section of the claw ring is parallel to and abuts against the shell wall outside the limiting groove, and the sealing member is arranged in the sealing cavity in a form of being tightly attached to the middle section of the claw ring.
[0008] Furthermore, the outer edge of the claw ring is in close contact with the wall of the limiting groove away from the central axis of the shell, and the limiting groove outside the outer edge is a clearance space for the outer edge to make way when the outer edge is bent.
[0009] Furthermore, the inner wall of the shell is chamfered to form an escape space close to the inner edge of the claw ring and used for a plurality of claws at the inner edge of the claw ring to bend and escape when subjected to force.
[0010] Furthermore, the sealing bosses are arranged on the outer surface of the hose connection end in a manner of being butt-jointed in sequence along the axial direction of the shell, the cross-section of the sealing bosses is wedge-shaped, the diameter of the sealing bosses gradually decreases from the center of the shell to the port of the hose connection end, and the length of the inclined surface of a sealing boss closest to the port of the hose connection end is greater than the lengths of the inclined surfaces of other sealing bosses.
[0011] Furthermore, the outer surface of the threaded end cap is provided with a plurality of first anti-slip protrusions, and the outer surface of the middle portion of the shell is provided with a plurality of second anti-slip protrusions.
[0012] Furthermore, an inner edge of the port of the threaded end cap away from the center of the shell is provided with a bevel.
[0013] The beneficial effects of the utility model are:
[0014] 1) The structure of the soft and hard tube connector is simple. It is connected with the external thread section of the shell through the internal thread section of the threaded end cap, and a sealing cavity for setting a seal is formed in the port of the hard tube quick-insert end, which not only realizes the stable connection between the threaded end cap, the seal and the claw ring and the shell, but also facilitates assembly and reduces manufacturing costs.
[0015] 2) The connection between the soft and hard pipe connector and the external pipe is a detachable connection, so that both the connector and the external pipe can be reused. The hard pipe quick-plug end does not require the use of disassembly tools, and the external pipe can be disassembled by directly unscrewing the threaded end cap by hand; the claw ring adopts a non-closed ring structure, which can ensure that the claw ring can be easily removed from the external pipe when disassembling the pipe, thereby avoiding unnecessary damage to the surface of the external pipe by the claws on the claw ring.
[0016] 3) The flexible and rigid tube connector has a compact structure, and the seal and the claw ring are tightly arranged together in an inner cavity of the shell, which greatly reduces the insertion length of the external pipe. At the same time, the external pipe can be disassembled by directly unscrewing the threaded end cap by hand, so there is no need to reserve operating space for disassembly tools near the pipe docking position, which improves the feasibility and convenience of using the flexible and rigid tube connector on narrow pipelines.
[0017] 4) The claw ring is designed in a "U"-shaped structure, so that the outer edge of the claw ring can be embedded in the limiting groove of the shell, thereby enhancing the stability of the claw ring itself and improving the pressure-bearing capacity and pull-out resistance of the soft and hard pipe connector when locking the hard pipe.
[0018] 5) The seal of the quick-insert end of the hard pipe is set on the side of the claw ring away from the center of the shell. When connecting the external pipe, the external pipe and the seal form a sealing area on the pipe surface in sealed contact. No matter how many times the pipe is installed and removed, the sealing area on the pipe surface will never be affected by the claw ring, thereby forming a stable sealing effect.
[0019] 6) At least two sealing bosses are provided on the outer periphery of the hose connection end, thereby forming multiple sealing sections, which improve the sealing effect of the hose and prevent the hose from loosening. After the hose connection end is inserted into the hose, the multiple sealing bosses are relatively concave, which is convenient for subsequent temporary binding and reinforcement measures for the hose.

DETAILED DESCRIPTION
[0026] The utility model discloses a simple and detachable soft and hard pipe connector, such as Figures 1 to 5As shown in combination, the soft and hard tube connector includes a shell 1, a threaded end cover 2, a claw ring 3 and a sealing member 4, the two ends of the shell 1 in the axial direction are respectively a hard tube quick-insert end 5 for inserting a hard tube and a hose connecting end 6 for sleeve-connecting a hose, the hard tube quick-insert end 5 is provided with an external thread section 7 on the outer wall away from the center of the shell 1, the threaded end cover 2 is detachably connected to the shell 1 through the cooperation of the internal thread section 8 provided on the inner wall and the external thread section 7, the inner wall of the shell 1 close to the external thread section 7 is provided with a circle of limiting grooves 9, the claw ring 3 is a non-closed ring structure and has a "U"-shaped cross-sectional shape, the outer edge of the claw ring 3 is embedded in the limiting groove 9 and the remaining part extends along the wall of the shell 1 outside the end of the limiting groove 9 toward the center of the hard tube quick-insert end 5, the sealing member 4 is arranged in a sealing cavity 10 between the claw ring 3 and the threaded end cover 2, and the outer surface of the hose connecting end 6 is provided with at least two circles of sealing bosses 11.
[0027] It should be noted that the above embodiment is that the structure of the soft and hard tube connector is simple. During assembly, the claw ring 3 is installed in the shell 1 along the direction in which its outer edge cooperates with the limit groove 9, and then the seal 4 is placed in the space of the shell 1 outside the claw ring 3, and then connected with the external thread section 7 of the shell 1 through the internal thread section 8 of the threaded end cover 2. After the threaded end cover 2 is assembled to the port of the hard tube quick-insert end 5, a sealing cavity 10 for setting the seal 4 will be formed in the port of the hard tube quick-insert end 5 between the threaded end cover 2 and the claw ring 3, which not only realizes a firm connection between the threaded end cover 2, the seal 4 and the claw ring 3 and the shell 1, but also facilitates assembly and reduces manufacturing costs.
[0028] The connection between the soft and hard pipe connector and the external pipe is a detachable connection. The external pipe connected to the soft and hard pipe connector can be reused on other pipe connectors after disassembly. The hard pipe quick-plug end 5 does not require a disassembly tool, and the external pipe can be disassembled by directly unscrewing the threaded end cap 2 by hand; the claw ring 3 adopts a non-closed ring structure, which can ensure that the external pipe can be easily removed from the claw ring 3 when disassembling the pipe, thereby avoiding unnecessary damage to the surface of the external pipe by the claws 13 on the claw ring 3.
[0029] The soft and hard tube connector has a compact structure, and the seal 4 and the claw ring 3 are tightly arranged together and coexist in an inner cavity in the shell 1, which can greatly reduce the insertion length of the external pipe connection. At the same time, the external pipe can be disassembled by directly unscrewing the threaded end cap 2 by hand, so there is no need to reserve operating space for disassembly tools near the pipe docking position, which improves the feasibility and convenience of using the soft and hard tube connector on narrow pipelines.
[0030] The claw ring 3 is designed with a "U"-shaped structure, so that the outer edge of the claw ring 3 can be embedded in the limiting groove 9 of the shell 1, thereby enhancing the stability of the claw ring 3 itself. When the hard tube fixed by the hard tube quick-insert end 5 is subjected to water pressure, the claw ring 3 will generate an extrusion force away from the center direction of the shell 1, and the outer edge of the claw ring 3 is arranged in the limiting groove 9 in an embedded form. When subjected to extrusion stress, the extrusion stress can be offset by the abutment between itself and the wall surface of the shell 1 in the limiting groove 9 and its own deformation, thereby maintaining its own position in the soft and hard tube connector unchanged, thereby improving the pressure-bearing capacity and anti-pull-out ability of the soft and hard tube connector when locking the hard tube.
[0031] The seal 4 of the hard pipe quick-insert end 5 is arranged on the side of the claw ring 3 away from the center of the shell 1. When the external pipe is connected, the external pipe and the seal 4 form a pipe surface sealing area in sealed contact. No matter how many times the pipe is installed and removed, the pipe surface sealing area will never be affected by the claw ring 3, thereby forming a stable sealing effect.
[0032] At least two sealing bosses 11 are provided on the periphery of the hose connection end 6, thereby forming a multiple sealing section. The butt joint between the small diameter end and the large diameter end of the two sealing bosses 11 is used to limit the port of the hose, thereby improving the sealing effect of the hose and improving the anti-loosening effect of the hose. After the hose is inserted between the multiple sealing bosses 11, it is convenient to take temporary binding and reinforcement measures for the hose later.
[0033] As a further preference of the above embodiment, Figure 4 As shown, the middle section of the claw ring 3 is parallel to the wall of the housing 1 outside the limiting groove 9 , and the sealing member 4 is arranged in the sealing cavity 10 in a form of being close to the middle section of the claw ring 3 .
[0034] Among them, one end of the sealing member 4 is tightly attached to the middle section of the claw ring 3. When the hard tube is inserted into the hard tube quick-insert end 5, the sealing member 4 presses the middle section of the claw ring 3 against the wall of the shell 1 outside the limiting groove 9, thereby maintaining the position of the claw ring 3. When the hard tube fixed by the hard tube quick-insert end 5 is subjected to water pressure, an extrusion force away from the center of the shell 1 is generated on the claw ring 3. The middle section of the claw ring 3 is pressed against the wall of the shell 1 outside the limiting groove 9 through the sealing member 4, thereby maintaining the position of the claw ring 3 in the soft and hard tube connector.
[0035] As a further preference of the above embodiment, Figure 4 As shown, the outer edge of the claw ring 3 is in close contact with the wall of the limiting groove 9 away from the central axis of the shell 1, and the limiting groove 9 outside the outer edge is a clearance space 12 for making way when the outer edge is bent.
[0036] Among them, when the hard tube fixed by the hard tube quick-insert end 5 is subjected to water pressure, the hard tube will generate extrusion stress on the claw ring 3 away from the center direction of the shell 1, and the outer edge of the claw ring 3 is embedded in the limit groove 9. When subjected to extrusion stress, it can offset the extrusion stress through the abutment between itself and the wall surface of the shell 1 in the limit groove 9 and its own deformation. When the claw ring 3 is deformed, the clearance space 12 can provide a buffer position for the outer edge of the claw ring 3 when it is deformed, so that the outer edge of the claw ring 3 extends into the space to avoid cracks in the claw ring 3 caused by the extrusion stress.
[0037] As a further preference of the above embodiment, Figure 4 As shown, the inner wall of the housing 1 is chamfered to form an escape space 14 close to the inner edge of the claw ring 3 and used for a plurality of claws 13 at the inner edge of the claw ring 3 to bend and escape when subjected to force.
[0038] Among them, after the hard tube is inserted into the hard tube quick-insert end 5, the hard tube will squeeze the several claws 13 at the inner edge of the claw ring 3, so that the claws 13 swing toward the direction close to the inner wall of the shell 1 to provide space for the center of the claw ring 3 to insert the hard tube, and the avoidance space 14 can provide an avoidance space for the claws 13 that open outward after being squeezed. The claws 13 swinging into the avoidance space 14 can avoid permanent deformation caused by hard squeezing with the inner wall of the shell 1, which is beneficial to maintaining the shape of the claw ring 3.
[0039] As a further preference of the above embodiment, Figure 2 and Figure 3 As shown in the combination, the sealing bosses 11 are arranged on the outer surface of the hose connecting end 6 in the form of being butt-jointed in sequence along the axial direction of the shell 1. The cross-section of the sealing bosses 11 is wedge-shaped. The diameter of the sealing bosses 11 gradually decreases from the center of the shell 1 to the port of the hose connecting end 6. The length of the inclined surface of the sealing boss 11 closest to the port of the hose connecting end 6 is greater than the lengths of the inclined surfaces of other sealing bosses 11.
[0040] Among them, by arranging a plurality of sealing bosses 11 with a wedge-shaped cross section on the outer wall of the shell 1 outside the hose connection end 6, a sealing section with a wave-like appearance is formed on the outer wall of the shell 1 outside the hose connection end 6, and the hose is sleeved outside the sealing bosses 11 at different positions, and the port of the hose is sleeved at the docking position of the small diameter end and the large diameter end between the two sealing bosses 11, thereby forming a limit for the port of the hose; and the first sealing boss 11 at the hose connection end 6 has a longer inclined surface than other sealing bosses 11, which can facilitate the introduction of the hose.
[0041] As one of the embodiments of the present utility model, Figure 1 and Figure 2As shown in the figure, the outer surface of the threaded end cap 2 is provided with a plurality of first anti-slip protrusions 15 , and the outer surface of the middle part of the shell 1 is provided with a plurality of second anti-slip protrusions 16 .
[0042] Among them, the first anti-skid protrusion 15 can play an anti-skid role when people twist the threaded end cover 2, and the second anti-skid protrusion 16 can facilitate people to take the shell 1 when assembling the soft and hard tube connector, and can also rotate the hard tube connector when installing the hard tube or hose.
[0043] As one of the embodiments of the present utility model, Figure 3 As shown, the inner edge of the port of the threaded end cap 2 away from the center of the housing 1 is provided with a circle of bevel 17.
[0044] Among them, the bevel 17 can guide the end of the hard tube when it is inserted into the hard tube quick-insert end 5, so as to facilitate the end of the hard tube to enter the through hole in the middle of the threaded end cover 2, making the installation and insertion operation of the hard tube simple.
[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
