Description

Technical Field

[0001] The utility model relates to the technical field of faucets, and particularly relates to an installation structure of an outer pipe of a faucet. Background Art

[0002] On the current pull-out faucet, there is usually an outer pipe of the faucet. One end of the outer pipe of the faucet is rotatably installed on the faucet base, and the other end is for the plug-in installation of the pull-out head.

[0003] During transportation, if the outer pipe of the faucet and the faucet base are installed together, it will occupy more space. If the outer pipe of the faucet and the faucet base are separated, although the problem of space occupation during transportation can be solved, however, the current assembly of the outer pipe of the faucet and the faucet base is not convenient enough. Letting the user install it by themselves not only causes inconvenience to the user, but also is likely to reduce the reliability during use.

[0004] If the assembly of the outer pipe of the faucet and the faucet base can be designed to be more convenient to operate and the reliability during use can be taken into account, so that the user can easily assemble the outer pipe of the faucet and the faucet base together by themselves, the above problems can be solved. Content of the Utility Model

[0005] The purpose of the utility model is to provide an installation structure of an outer pipe of a faucet, to overcome the above defects, and to make the assembly of the outer pipe of the faucet and the faucet base more convenient and take into account the reliability during use.

[0006] To achieve the above purpose, the solution of the utility model is: an installation structure of an outer pipe of a faucet, used for installing the outer pipe of the faucet on the faucet base, including an inner snap ring and an outer snap ring;

[0007] An outer pipe channel is formed inside the outer pipe of the faucet;

[0008] A connecting head is formed by the protrusion of the faucet base;

[0009] The inner snap ring is rotatably sleeved around the outer periphery of the connecting head and is axially limited on the connecting head to form a connecting head assembly with the connecting head;

[0010] The outer snap ring is fixed at one end of the outer pipe channel. The outer snap ring can be detachably sleeved on the connecting head assembly. After being sleeved on the connecting head assembly, the outer snap ring is axially clamped and limited on the connecting head assembly, and the inner wall of the outer snap ring fits with the outer wall of the inner snap ring and is circumferentially clamped and fixed with the inner snap ring, so that the outer snap ring and the outer pipe of the faucet can rotate with the inner snap ring sleeved around the outer periphery of the connecting head.

[0011] Further, the connector is in a circular tubular shape, and a first clamping groove is recessed on the outer peripheral wall of the connector. The first clamping groove extends in a ring shape around the outer periphery of the connector for one circle. A plurality of first clamping claws are arranged on the inner clamping ring at intervals in a surrounding manner. The plurality of first clamping claws protrude towards the inside of the inner clamping ring. After the inner clamping ring is sleeved on the outer periphery of the connector, each first clamping claw extends into and is clamped in the first clamping groove, so that the inner clamping ring is rotationally sleeved on the outer periphery of the connector and is axially limited on the connector.

[0012] Further, the connector is in a circular tubular shape, and a second clamping groove is recessed on the outer peripheral wall of the connector. The second clamping groove extends in a ring shape around the outer periphery of the connector for one circle. After the inner clamping ring is sleeved on the outer periphery of the connector, the second clamping groove is exposed outside the inner clamping ring. A plurality of second clamping claws are arranged on the outer clamping ring at intervals in a surrounding manner. The plurality of second clamping claws protrude towards the inside of the outer clamping ring. After the outer clamping ring is sleeved on the outer periphery of the connector assembly, each second clamping claw extends into and is clamped in the second clamping groove, so that the outer clamping ring is axially clamped on the connector assembly.

[0013] Further, a first groove and / or a first protrusion is / are arranged on the outer wall of the inner clamping ring, and a second protrusion is arranged on the inner wall of the outer clamping ring corresponding to the first groove, and a second groove is arranged corresponding to the first protrusion. When the outer clamping ring is sleeved on the outer periphery of the inner clamping ring, the first protrusion is embedded in the second groove, and the second protrusion is embedded in the first groove, so as to circumferentially clamp and fix the outer clamping ring and the inner clamping ring.

[0014] Further, the first groove is in a shape that gradually converges towards the direction close to the faucet base, and the second protrusion matches the shape of the first groove and is in a shape that gradually converges towards the direction close to the faucet base; the first protrusion is in a shape that gradually expands towards the direction close to the faucet base, and the second groove matches the shape of the first protrusion and is in a shape that gradually expands towards the direction close to the faucet base. During installation, the outer clamping ring is sleeved on the inner clamping ring along the axial direction towards the direction close to the faucet base, so that the second protrusion slides into the first groove and the first protrusion slides into the second groove.

[0015] Further, a washer is sleeved on the outer periphery of the connector, and the inner wall of the inner clamping ring abuts against the washer.

[0016] Further, a plurality of washers are provided, and the plurality of washers are arranged at intervals in the radial direction of the connector and are respectively used to abut against different positions on the inner wall of the inner clamping ring.

[0017] Further, a first channel longitudinally penetrates through the faucet base. The connector is in a tubular shape and is fixed at the top end of the faucet base and is communicated with the top end of the first channel. After the faucet outer tube is sleeved and installed on the connector assembly along with the outer clamping ring, the top end of the connector extends into the bottom end of the outer tube channel. The middle part of the outer tube channel extends upwards and then bends into a bent tubular shape, and a pull head is detachably installed at the end. The pull head is connected with a pull hose. The pull hose passes through the outer tube channel, the connector and the first channel in sequence from the pull head and is used to connect to a water source device.

[0018] Further, the outer snap ring is inserted and fixed into the outer tube channel.

[0019] Further, the inner snap ring and the outer snap ring are made of plastic, the first and second clamping claws can elastically deform, and the faucet outer tube and the faucet base are made of metal.

[0020] After adopting the above scheme, the beneficial effects of the utility model are as follows:

[0021] (1) The inner snap ring is rotatably sleeved on the outer periphery of the connector and axially limited on the connector to form a connector assembly with the connector. An outer tube channel is formed in the faucet outer tube. The outer snap ring is fixed at one end of the outer tube channel. Before leaving the factory, the inner snap ring and the connector can be pre-assembled together, and the outer snap ring and the faucet outer tube can be pre-assembled together; the outer snap ring can be detachably sleeved on the connector assembly. After being sleeved on the connector assembly, the outer snap ring is axially clamped on the connector assembly, and the inner wall of the outer snap ring fits with the outer wall of the inner snap ring and is circumferentially clamped and fixed with the inner snap ring, so that the outer snap ring and the faucet outer tube can rotate with the inner snap ring sleeved on the outer periphery of the connector. Thus, the user can complete the installation by simply sleeving the faucet outer tube with the outer snap ring on the connector assembly, making the assembly of the faucet outer tube and the faucet base more convenient;

[0022] (2) Moreover, since the assembly of the inner snap ring, which has higher requirements for precision and assembly, and the rotation of the connector does not need to be completed by the user himself, the user only needs to complete the circumferential clamping of the outer snap ring and the inner snap ring, and make the outer snap ring and the faucet outer tube rotate with the inner snap ring. The assembly requirements are lower, and the reliability after the user's self-assembly can be guaranteed;

[0023] (3) Through the design of the inner snap ring and the outer snap ring, during the disassembly and assembly of the faucet outer tube and the faucet base, direct friction will not be generated between the two, ensuring that the faucet outer tube and the faucet base itself will not be worn during repeated disassembly and assembly.

Detailed implementation manners

[0031] The following will describe the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0032] The embodiments of the present invention will be described comprehensively hereinafter with reference to the accompanying drawings. It should be noted that the present invention can be implemented in different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present disclosure thorough and complete and to fully convey the scope of the present invention to those skilled in the art.

[0033] The present utility model provides an installation structure for the outer tube of a faucet. As Figures 1-6 shown, it is used to install the outer tube 1 of the faucet on the base 2 of the faucet, and includes an inner snap ring 3 and an outer snap ring 4; an outer tube channel 5 is formed inside the outer tube 1 of the faucet; a connector 6 is formed by the protrusion of the base 2 of the faucet; the inner snap ring 3 is sleeved around the outer periphery of the connector 6 and is axially limited on the connector 6. Any existing connection structure that can rotate around the axis and be axially limited and fixed can be used for the connection between the two, without specific limitation, so as to form a connector assembly 7 with the connector 6;

[0034] The external snap ring 4 is fixed at one end of the outer pipe channel 5. Specifically, in this embodiment, the external snap ring 4 is inserted and fixed inside the outer pipe channel 5. Of course, it can also be arranged to fix the external snap ring 4 outside the outer pipe channel 5, without specific limitation. The external snap ring 4 can be detachably sleeved on the connector assembly 7. After being sleeved on the connector assembly 7, the external snap ring 4 is axially clamped on the connector assembly 7. It can be designed to be clamped on the connector 6 of the connector assembly 7, or can be designed to be clamped on the internal snap ring 3 of the connector assembly 7, as long as it can be axially limited, without specific limitation. And the inner wall of the external snap ring 4 fits with the outer wall of the internal snap ring 3 (the purpose is to ensure that the faucet outer pipe 1 will not shake after installation), and is circumferentially clamped and fixed with the internal snap ring 3, so that the external snap ring 4 and the faucet outer pipe 1 can rotate along with the internal snap ring 3 sleeved on the outer periphery of the connector 6. Thus, before leaving the factory, the internal snap ring 3 is assembled with the connector 6, and the external snap ring 4 and the faucet outer pipe 1 are assembled. After the user purchases, the user can simply insert and assemble the connector 6 with the external snap ring 4 and the faucet outer pipe 1 with the internal snap ring 3, which not only ensures the convenience of user assembly but also ensures the reliability after assembly.

[0035] Specifically, in this embodiment, this faucet outer pipe installation structure is applied to a pull-out faucet. The faucet base 2 is longitudinally penetrated by a first channel 17. The connector 6 is tubular and fixed at the top of the faucet base 2, communicating with the top end of the first channel 17. After the faucet outer pipe 1 is sleeved and installed on the connector assembly 7 along with the external snap ring 4, the top end of the connector 6 extends into the bottom end of the outer pipe channel 5. The middle part of the outer pipe channel 5 extends upward and then bends into a bent tube shape, and a pull-out head 18 is detachably installed at the end. The pull-out head 18 is connected with a pull-out hose 19. The pull-out hose 19 passes through the outer pipe channel 5, the connector 6, and the first channel 17 in sequence from the pull-out head 18 and is used to connect to a water source device; of course, this faucet outer pipe installation structure can also be arranged on a non-pull-out faucet where the outer pipe channel 5 of the faucet outer pipe 1 and the first channel 17 of the faucet base 2 directly supply water flow to pass through without setting the pull-out head 18 and the pull-out hose 19.

[0036] Preferably, in the present embodiment, the installation method between the inner snap ring 3 and the connecting head 6 is as follows: the connecting head 6 is in the shape of a circular tube, and a first groove 8 is recessed on the outer peripheral wall of the connecting head 6. The first groove 8 is annular and extends around the outer periphery of the connecting head 6. A plurality of first claws 9 are arranged in an interval array around the inner snap ring 3. Specifically, each first claw 9 is located at the top edge of the inner snap ring 3, and a plurality of first claws 9 protrude inwardly of the ring of the inner snap ring 3. After the inner snap ring 3 is sleeved on the outer periphery of the connecting head 6, each first claw 9 extends into and is clamped in the first groove 8, so that the inner snap ring 3 is rotatably sleeved on the outer periphery of the connecting head 6, and is axially upper-limited on the connecting head 6. ; More preferably, in order to reduce the wear between the inner retaining ring 3 and the connecting head 6 caused by the rotation of the inner retaining ring 3, a gasket 16 is provided on the outer periphery of the connecting head 6, and the inner wall of the inner retaining ring 3 is abutted against the gasket 16. Through the provision of the gasket 16, on the one hand, the contact area can be reduced, that is, the friction surface is reduced, so that the rotation of the inner retaining ring 3 is smoother and more durable. On the other hand, after wear, only the gasket 16 needs to be replaced, and the maintenance cost is lower. In order to make the rotation of the inner retaining ring 3 more stable, it is more preferred that a plurality of gaskets 16 are provided, and the plurality of gaskets 16 are arranged at intervals along the radial direction of the connecting head 6, and are respectively used to abut against the inner wall of the inner retaining ring 3 at different positions along the axial direction.

[0037] In order to make the structure more reliable and stable, it is preferred that in this embodiment, the outer clamping ring 4 is axially clamped on the connecting head assembly 7 in the following manner: the connecting head 6 is in the shape of a circular tube, and a second clamping groove 10 is recessed on the outer peripheral wall of the connecting head 6. The second clamping groove 10 is annular and extends around the outer periphery of the connecting head 6. After the inner clamping ring 3 is sleeved on the outer periphery of the connecting head 6, the second clamping groove 10 is exposed outside the inner clamping ring 3. A plurality of second clamping claws 11 are arranged in an interval array around the outer clamping ring 4, and each second clamping claw 11 is located at the top edge of the outer clamping ring 4. The second claws 11 protrude inside the outer clamping ring 4. After the outer clamping ring 4 is sleeved on the outer periphery of the connector assembly 7, each second claw 11 extends into the second clamping groove 10 to clamp the outer clamping ring 4 on the connector assembly 7 in the axial direction. Therefore, after the faucet outer tube 1 is installed, when it is subjected to overturning or upward pulling forces, the force will not be completely applied to the inner clamping ring 3 through the outer clamping ring 4, avoiding affecting the rotation of the inner clamping ring 3 on the connector 6. Furthermore, when the faucet outer tube 1 is plugged in and out, the stability of the assembly between the inner clamping ring 3 and the connector 6 will not be affected.

[0038] For the convenience of circumferentially clamping and fixing the inner snap ring 3 and the outer snap ring 4, preferably in this embodiment, the outer wall of the inner snap ring 3 is provided with a first groove 12 and a first protrusion 13 at circumferential intervals, that is, one first groove 12 is provided between two adjacent first protrusions 13. The inner wall of the outer snap ring 4 is provided with a second groove 14 and a second protrusion 15 at circumferential intervals. When the outer snap ring 4 is sleeved on the outer periphery of the inner snap ring 3, the first protrusion 13 is embedded in the second groove 14, and the second protrusion 15 is embedded in the first groove 12 to circumferentially clamp and fix the outer snap ring 4 and the inner snap ring 3. Of course, only the first groove 12 and the second protrusion 15 can be provided, or only the first protrusion 13 and the second groove 14 can be provided.

[0039] To further facilitate the insertion and assembly of the faucet outer tube 1 and the faucet base 2, the first groove 12 is in a V shape that gradually converges towards the faucet base 2, and the second protrusion 15 matches the shape of the first groove 12 and is in a V shape that gradually converges towards the faucet base 2; the first protrusion 13 is in a V shape that gradually expands towards the faucet base 2, and the second groove 14 matches the shape of the first protrusion 13 and is in a V shape that gradually expands towards the faucet base 2. During installation, the outer snap ring 4 is sleeved onto the inner snap ring 3 along the axial direction towards the faucet base 2, so that the second protrusion 15 slides into the first groove 12 and the first protrusion 13 slides into the second groove 14. Thus, through the guidance of the V shape, it is not necessary for the installer to deliberately align the grooves and protrusions during the installation process.

[0040] The inner snap ring 3 and the outer snap ring 4 are made of plastic material, and the first claw 9 and the second claw 11 can elastically deform so as to deform and make way when being sleeved on the connector 6, and then restore their shapes when reaching the corresponding first card slot 8 and second card slot 10, and are snapped into the first card slot 8 and the second card slot 10. The faucet outer tube 1 and the faucet base 2 are made of metal material.

[0041] The above is only the preferred embodiment of the present invention, and it does not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
