the side wall of the retaining ring 3 is circumferentially provided with a sinking groove 32 communicated with the through hole 31 and an opening groove 33 which axially penetrates through the side wall of the retaining ring 3 along the retaining ring 3;
the retaining ring 3 is arranged between the extension pipe 1 and the reversing joint 2, the retaining ring 3 is axially arranged on the outer wall of the reversing joint 2 or the outer wall of the extension pipe 1 in a limiting mode, the fastening piece 4 penetrates through the extension pipe 1 or the reversing joint 2 and abuts against the hole wall 311 of the through hole 31, and the hole wall 311 of the through hole 31 deforms towards one side where the sink groove 32 is located.
From the above description, the beneficial effects of the utility model reside in that: after the retaining ring 3 is arranged between the reversing joint 2 and the extension pipe 1 and is axially and limitedly arranged on the outer wall of the reversing joint 2 or the extension pipe 1, the retaining ring 3 is fixed with the reversing joint 2 or the extension pipe 1 into a whole, the fastening piece 4 penetrates through the extension pipe 1 or the reversing joint 2 and is pressed against the hole wall 311 of the through hole 31, the fastening piece 4 fixes the extension pipe 1 and the reversing joint 2 in the radial direction, external force cannot pull the extension pipe 1 and the reversing joint 2 away in the axial direction and the radial direction, and the extension pipe 1 or the reversing joint 2 can only rotate relatively in the circumferential direction; meanwhile, as the hole wall 311 of the through hole 31 is deformed towards one side of the sink 32 under the pressure of the fastening piece 4, the hole wall 311 of the through hole 31 generates a reaction force to the fastening piece 4, so that the fastening piece 4 is compressed by the reaction force, the locking function of the fastening piece 4 can be realized, the fastening piece 4 is prevented from accidentally dropping in long-term use, and the reversing joint 2 is prevented from being separated from the extension pipe 1, and the connection reliability is ensured; through above structure, buckle 3 has replaced original fastener 4 and reversing joint 2 or extension pipe 1's direct contact and friction as the adapter in reversing joint 2 and extension pipe 1's rotation, thereby both reduced frictional force and guaranteed the pivoted flexibility, avoid again that reversing joint 2 and extension pipe 1 are worn and torn by fastener 4 in long-term friction use, reach the purpose that improves water injection well nozzle extender life, even buckle 3 produces comparatively serious wearing and tearing after using for a long time, as long as use buckle 3 of new buckle 3 replacement wearing and tearing, just can ensure that whole water injection well nozzle extender can be used continuously.
In the present embodiment, the circumferential width of the sink groove 32 on the retaining ring 3 is smaller than or equal to the inner diameter of the retaining ring 3.
As can be seen from the above description, the width of the sinking groove 32 affects the reliability of the connection, and the above solution can facilitate the installation of the fastening member 4 and ensure the flexible relative movement between the reversing connector 2 and the extension pipe 1.
In the present embodiment, the sink grooves 32 communicate with each other at both ends in the axial direction of the grommet 3.
As can be seen from the above description, the axial disposition of the undercut 32 through the eye allows the force required to deform the bore wall 311 to be reduced, facilitating assembly of the fastener 4.
In the embodiment, the radial depth of the sinking groove 32 on the retaining ring 3 is 10% to 30% of the wall thickness of the retaining ring 3.
As can be seen from the above description, the radial depth of the sink groove 32 is too deep or too shallow, which affects the reliability of the connection, i.e. if the radial depth of the sink groove 32 is too large, the hole wall 311 of the through hole 31 is too thin and is easy to break; if the radial depth of the sinking groove 32 is too small, a larger pressure is required to deform the hole wall 311 of the through hole 31 when the fastening member 4 is installed, and the depth range of the sinking groove 32 is limited while taking into account the above two factors.
In this embodiment, the outer wall of the retaining ring 3 is provided with a counter bore 34 communicating with the through hole 31, and the diameter of the counter bore 34 is larger than that of the fastening member 4.
As can be seen from the above description, since the retaining ring 3 cannot make the through hole 31 completely face the installation direction of the fastener 4 in actual installation, the counter bore 34 with a diameter larger than that of the fastener 4 can be used for guiding the installation of the fastener 4, so that the fastener 4 can enter the through hole 31 more easily, and the assembly difficulty is reduced.
In the present embodiment, the width of the opening groove 33 is smaller than the inner diameter of the retaining ring 3.
As can be seen from the above description, the larger the width of the opening slot 33 is, the easier the snap ring 3 can be snapped into the reversing connector 2 or the extension pipe 1, but if the width of the opening slot 33 exceeds the inner diameter of the snap ring 3, the snap ring 3 cannot be snapped onto the reversing connector 2 or the extension pipe 1 by itself, so that there is a possibility of dropping during assembly, and therefore, the width of the opening slot 33 is smaller than the inner diameter of the snap ring 3, which is more beneficial for assembly.
In the present embodiment, in an axial view of the grommet 3, an obtuse angle is formed between the central axis of the open groove 33 and the axis of the through-hole 31.
As can be seen from the above description, the central axis of the open slot 33 and the axis of the through hole 31 form an obtuse angle, so that the width of the open slot 33 is prevented from being too large, the coverage area of the open slot 33 in the circumferential region is enlarged, the assembly difficulty of the retaining ring 3 can be reduced, and the retaining ring 3 can be prevented from falling off due to the width limitation of the open slot 33, under the condition that the circumferential region covered by the open slot 33 is maximized.
In this embodiment, the fastener 4 is threadedly coupled to the extension pipe 1 or the reversing connector 2.
As can be seen from the above description, the connection tightness can be improved by adopting the manner of threaded connection, and the connection reliability can be further improved.
In the embodiment, a limiting cavity 5 is formed between the reversing connector 2 and the extension pipe 1, and the retaining ring 3 is embedded in the limiting cavity 5, so that the retaining ring 3 is axially limited.
From the above description, the formation of the limiting cavity 5 can axially limit the retaining ring 3, and improve the connection stability of the retaining ring 3.
In the embodiment, the water outlet joint 6 is also included; the other end of the reversing joint 2 is rotatably connected with a water outlet joint 6;
the retaining ring 3 is arranged between the water outlet joint 6 and the other end of the reversing joint 2, the retaining ring 3 is axially arranged on the outer wall of the water outlet joint 6 or the inner wall of the other end of the reversing joint 2 in a limiting manner, and the fastening piece 4 penetrates through the extension pipe 1 or the reversing joint 2 and is pressed against the hole wall 311 of the through hole 31, so that the hole wall 311 of the through hole 31 deforms towards one side of the sink groove 32.
As can be seen from the above description, the mode of connecting the water outlet joint 6 and the reversing joint 2 by the retaining ring 3 and the fastening piece 4 ensures the reliability, flexibility and low abrasion of the connection between the water outlet joint 6 and the reversing joint 2.
