Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically to a connecting base for spring-loaded faucets. Background Technology

[0002] A spring-loaded faucet is one in which a spring is incorporated inside the faucet's extension tube, allowing the faucet to extend and retract freely. This type of faucet has a simple appearance and is easy to use. Its biggest advantage is its free extension and retraction, making it very flexible to use. At the same time, spring-loaded faucets are also relatively durable and have a longer service life.

[0003] like Figure 1 As shown, the spring-loaded faucet connecting base in the prior art includes a lower tube body 1', an upper tube body 2' welded to the upper end of the lower tube body 1', an internal thread 3' formed on the inner wall of the upper end of the upper tube body 2', a water outlet pipe 4' formed on the upper end of the upper tube body 2', a connecting plug 5' fixedly set at one end of the water outlet pipe 4', a connecting groove 6' formed on the connecting plug 5', a threaded sleeve 7' rotatably set on the connecting plug, located in the connecting groove 6' and threadedly connected to the internal thread 3', an outer sleeve 8' set on the periphery of the upper tube body 2', a connecting bolt 9' threadedly connected between the outer sleeve 8' and the upper tube body 2', and a connecting rod 10' fixedly set on the periphery of the outer sleeve 8'.

[0004] Because the outer sleeve of some spring faucets needs to rotate on the upper pipe body, and needs to be placed between the upper pipe body and the rotating sleeve during subsequent spring installation, the inner and outer diameters of the upper pipe body and the lower pipe body have a large deviation. Usually, in order to reduce production costs, the upper pipe body and the lower pipe body are processed and produced separately. However, after production is completed, the upper pipe body and the lower pipe body still need to be welded and fixed, making it difficult to further reduce production and assembly costs. Utility Model Content

[0005] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a connecting base for spring-loaded faucets.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a connecting base for a spring-loaded faucet, comprising a lower tube body, an upper tube body disposed at the upper end of the lower tube body, an outer sleeve disposed on the outside of the upper tube body, a connecting plug disposed at the upper end of the upper tube body, and a water outlet pipe disposed on the connecting plug. The lower end of the upper tube body is sleeved on the upper end of the lower tube body. A connecting insertion hole for inserting the connecting plug into the upper tube body is provided through the upper tube body. Corresponding holes are respectively opened on the lower tube body, the upper tube body, and the outer sleeve for corresponding positions after the lower tube body, the upper tube body, and the outer sleeve are connected. A corresponding annular groove is opened on the connecting plug for corresponding positions after the connecting plug is inserted into the connecting insertion hole. A connecting rod is disposed between the lower tube body, the upper tube body, and the outer sleeve within the corresponding hole, with one end of the connecting rod located within the corresponding annular groove.

[0007] A further improvement is that the corresponding holes include corresponding openings, connecting holes, and external openings respectively opened on the lower tube body, upper tube body, and outer sleeve for corresponding positions after the lower tube body, upper tube body, and outer sleeve are connected. The connecting rod passes through the corresponding openings, connecting holes, and external openings and is located in the corresponding annular groove. A fixing member is provided between the connecting rod and the lower tube body, upper tube body, or outer sleeve for fixing or releasing the connecting rod between the lower tube body, upper tube body, and outer sleeve.

[0008] Further effect: After aligning the corresponding openings, connecting holes, and external openings on the lower tube body, upper tube body, and outer sleeve, insert the connecting rod into the corresponding openings, connecting holes, and external openings, ensuring that one end of the connecting rod is located in the corresponding annular groove. Then, fix the connecting rod between the lower tube body, upper tube body, and outer sleeve using fasteners to prevent the connecting rod from falling off between the lower tube body, upper tube body, and outer sleeve, thus achieving the assembly and fixation of the lower tube body, upper tube body, and outer sleeve.

[0009] A further improvement is that the fastener includes a connecting rod threadedly connected to the corresponding opening, connecting hole, or external opening.

[0010] Further benefits: The connecting rod is fixed by the threaded connection between the connecting rod and the lower tube body, upper tube body, and outer sleeve, and it is also easy to control the connecting rod when it is necessary to release the fixation.

[0011] A further improvement is that a hexagonal slot is provided on the side end face of the upper tube body, and a hexagonal nut is provided in the hexagonal slot on the upper tube body. The hexagonal slot is connected to the connecting hole, and the connecting rod is threaded onto the hexagonal nut.

[0012] Further effects: When the connecting rod is threadedly connected to the hexagonal nut, the hexagonal slot can restrict the rotation of the hexagonal nut. When the connecting rod is threadedly connected to the hexagonal nut, it will drive the hexagonal nut to move towards the lower tube body. The hexagonal nut and the connecting rod will press the lower tube body and the outer sleeve together, thereby fixing the lower tube body, the upper tube body and the outer sleeve.

[0013] A further improvement is that the upper tube body is provided with a limiting step for restricting the downward movement of the connector plug in the connector socket when the corresponding annular groove is aligned with the position of the connector socket after the connector plug is inserted into the connector socket. The diameter or side length of the limiting step is smaller than the diameter of the connector socket.

[0014] A further improvement is that a rotating assembly is fitted onto the connector plug in the corresponding annular groove. The rotating assembly is rotatably mounted on the connector plug in the corresponding annular groove. A locking annular groove is formed around the circumference of the rotating assembly. After the connector plug is inserted into the connector hole, the locking annular groove corresponds to the position of the connector hole, and one end of the connector rod is located in the locking annular groove.

[0015] Further effects: The rotating assembly is locked in the corresponding annular groove, which restricts the up and down movement of the rotating assembly. The connecting rod can be directly pressed against the rotating assembly in the locking annular groove, thereby restricting the lifting and lowering of the connecting plug. The rotating assembly can also rotate on the connecting plug, reducing the friction between the rotating assembly and the connecting plug.

[0016] A further improvement is that the rotating assembly has a deformation opening.

[0017] Further benefits: When the rotating component is subjected to external pressure, the deformation opening allows the rotating component to undergo slight deformation, which can prevent the rotating component from cracking when the connecting rod is pressed against it. In addition, the deformation opening makes it easy to install or remove the rotating component from the corresponding annular groove.

[0018] A further improvement is that the upper tube body is provided with a resistance step to increase the lifting resistance of the connector plug in the connector hole when the locking ring groove corresponds to the position of the connector hole. The diameter of the resistance step is smaller than the diameter of the connector hole.

[0019] Further effect: A chamfered surface is provided at the junction of the upper end of the resistance step and the connection socket. The chamfered surface is used to contact the rotating component as the connecting plug descends, so that the rotating component locks into the connecting plug through the deformation opening.

[0020] A further improvement is made in that: a filling support is provided between the lower end of the upper tube and the outer sleeve; the filling support has an upper sliding hole that slides with the circumference of the upper tube and a lower sliding hole that slides with the circumference of the lower tube; the upper sliding hole and the lower sliding hole are connected; and the filling support has a mating opening corresponding to the position of the connecting hole after the filling support is connected to the upper and lower tubes; the mating opening is clearance-fitted with the connecting rod.

[0021] Further benefits: The filling support can play a filling and supporting role during the assembly of the upper tube body, lower tube body, and outer sleeve, preventing gaps between the upper tube body, lower tube body, and outer sleeve.

[0022] A further improvement is that a positioning block is provided on the lower tube body, and a positioning groove is provided on the filling support for engaging with the positioning block when the filling support is sleeved on the upper tube body and the matching opening corresponds to the connection hole.

[0023] Further effects: When assembling the filling support onto the upper tube body, by observing the position of the positioning block and the positioning groove and engaging them, the position of the mating opening corresponds to the position of the connecting hole, thus achieving the positioning effect between the connecting hole and the mating opening.

[0024] A further improvement is that the upper end face of the upper tube body is provided with a spring cavity for installing the spring.

[0025] A further improvement is that a support crossbar is provided on the side end face of the outer sleeve, one end of the support crossbar is connected to the outer sleeve, and the other end of the support crossbar is provided with a support sleeve.

[0026] After adopting the above technical solution, the beneficial effects of this utility model are as follows: After the production of components such as the lower pipe body, upper pipe body, and outer sleeve, the connector plug connected to the water outlet pipe is first inserted into the connector socket. Then, the lower end of the upper pipe body is fitted onto the upper end of the lower pipe body for connection. The outer sleeve is then fitted onto the outside of the upper pipe body until the corresponding holes of the lower pipe body, upper pipe body, and outer sleeve are aligned. Subsequently, the connecting rod is installed into the corresponding holes of the lower pipe body, upper pipe body, and outer sleeve, with one end of the connecting rod positioned in the corresponding annular groove. The gap fit between one end of the connecting rod and the corresponding annular groove restricts the lifting and lowering of the connector plug in the connector socket and allows the connector plug to rotate in the connector socket, thereby achieving the rotation effect of the water outlet pipe and preventing the water outlet pipe with the connector plug from detaching from the upper pipe body. The lower pipe body, upper pipe body, outer sleeve, connector plug, and water outlet pipe can be assembled and fixed at one time without the need for welding and fixing of accessories, which can further reduce production and assembly costs.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0031] See Figures 2 to 10As shown, the technical solution adopted in this specific embodiment is: a connecting base for a spring-loaded faucet, including a lower tube body 1, an upper tube body 2 disposed at the upper end of the lower tube body 1, an outer sleeve 3 disposed on the outside of the upper tube body 2, a connecting plug 4 disposed at the upper end of the upper tube body 2, and a water outlet pipe 5 disposed on the connecting plug 4. The lower end of the upper tube body 2 is sleeved on the upper end of the lower tube body 1. A connecting insertion hole 6 is provided through the upper tube body 2 for inserting the connecting plug 4 into the upper tube body 2 and allowing water flow. A connecting hole 7 is provided on the side end face of the upper tube body 2, and the connecting hole 7 communicates with the connecting insertion hole 6. A corresponding opening 8 is provided on the upper side of the lower tube body 1 for the position corresponding to the connecting hole 7 after the lower tube body 1 and the upper tube body 2 are connected. The side end face of the outer sleeve 3... An external opening 9 is provided for the outer sleeve 3 to be fitted onto the outer side of the upper tube 2, corresponding to the position of the connecting hole 7. A corresponding annular groove 10 is provided on the periphery of the connecting plug 4 for the connecting plug 4 to be inserted into the connecting socket 6, corresponding to the position of the connecting hole 7, the corresponding opening 8, or the external opening 9. A connecting rod 11 is provided between the lower tube 1, the upper tube 2, and the outer sleeve 3 for passing through the external opening 9, the corresponding opening 8, the connecting hole 7, and the corresponding annular groove 10 respectively when the positions of the connecting hole 7, the corresponding opening 8, and the external opening 9 are corresponding. One end of the connecting rod 11 is located in the corresponding annular groove 10. The connecting plug 4 is restricted from rising and falling in the connecting socket 6 by the gap fit between the corresponding annular groove 10 and one end of the connecting rod 11, and the connecting plug 4 can rotate in the connecting socket 6.

[0032] A fixing component is provided between the connecting rod 11 and the upper tube 2, lower tube 1, or outer sleeve 3 for fixing or unfixing the connecting rod 11 between the lower tube 1, upper tube 2, and outer sleeve 3 after the connecting rod 11 passes through the outer opening 9, the corresponding opening 8, the connecting hole 7, and the corresponding annular groove 10, so as to connect and fix the lower tube 1, upper tube 2, and outer sleeve 3.

[0033] The fasteners include: a connecting rod 11 threadedly connected to the corresponding opening 8, connecting hole 7, or external opening 9.

[0034] A hexagonal slot 17 is formed on the side end face of the upper tube body 2. A hexagonal nut 18 is installed in the hexagonal slot 17 on the upper tube body 2. The hexagonal slot 17 is connected to the connecting hole 7. The connecting rod 11 is threadedly connected to the hexagonal nut 18. The connecting rod 11 is a bolt, which is threaded to the hexagonal nut 18 through the threaded part. By restricting the position of the outer sleeve 3, the whole body is fixed. With the hexagonal nut 18 installed, the connecting rod 11 is clearance-fitted with the connecting hole 7, the corresponding opening 8, and the outer opening 9, respectively. The hexagonal nut 18 can be removed and installed from the hexagonal slot 17, which facilitates assembly, repair and replacement during production. The upper tube body 2 is provided with anti-slip protrusions in the hexagonal slot 17 to improve the friction of the hexagonal nut 18 in the hexagonal slot 17.

[0035] Without hexagonal nuts and hexagonal slots, the fasteners are as follows: the connecting rod 11 is threaded onto the upper tube 2 and located inside the connecting hole 7. When the connecting rod 11 is threaded onto the connecting hole 7, the corresponding opening 8 and the outer opening 9 are clearance-fitted with the connecting rod 11; or the connecting rod 11 is threaded onto the corresponding opening 8 on the lower tube 1. When the connecting rod 11 is threaded onto the corresponding opening 8, the connecting rod 11 is clearance-fitted with the connecting hole 7 and the outer opening 9; or the connecting rod 11 is threaded onto the outer opening 9, the connecting rod 11 is clearance-fitted with the corresponding opening 8 and the connecting hole 7.

[0036] When the connecting rod 11 is threadedly connected to the hexagonal nut 18, the hexagonal slot 17 can restrict the rotation of the hexagonal nut 18.

[0037] The upper tube 2 has a limiting step 12 for restricting the descent of the connector 4 in the connector socket 6 when the corresponding annular groove 10 aligns with the corresponding hole position. The diameter or side length of the limiting step 12 is smaller than the diameter of the connector socket 6. The limiting step 12 can be a circular or square opening. The diameter or side length of the limiting step 12 is smaller than the diameter of the resistance step 16. The corresponding annular groove 10 aligns with the corresponding hole 7 in the connector socket 6.

[0038] A rotating assembly 13 is fitted on the connector 4 in the corresponding annular groove 10. The rotating assembly 13 is rotatably mounted on the connector 4 in the corresponding annular groove 10. A locking annular groove 14 is formed around the circumference of the rotating assembly 13. After the connector 4 is inserted into the connector hole 6, the locking annular groove 14 corresponds to the position of the connector hole 7, and one end of the connector rod 11 is located in the locking annular groove 14.

[0039] The rotating assembly 13 is engaged in the corresponding annular groove 10, which restricts the up and down movement of the rotating assembly 13. The connecting rod 11 can directly press against the rotating assembly 13 and be located in the engaging annular groove 14, thereby restricting the lifting and lowering of the connecting rod 11 on the connecting plug 4. The rotating assembly 13 can rotate on the connecting plug 4, reducing the friction between the rotating assembly 13 and the connecting plug 4.

[0040] When the rotating assembly 13 is installed, one end of the connecting rod 11 is pressed against the periphery of the rotating assembly 13. Without the rotating assembly 13, the same rotation restriction effect can be achieved even with one end of the connecting rod 11 located within the corresponding annular groove 10. In this case, one end of the connecting rod 11 does not abut against the connecting plug 4, preventing excessive friction from affecting the rotation of the connecting plug 4 within the connecting socket 6. The rotating assembly 13 and the connecting plug 4 are fitted with a clearance fit.

[0041] The rotating assembly 13 has a deformation opening 15.

[0042] When the rotating assembly 13 is squeezed by external force, the deformation opening 15 allows the rotating assembly 13 to undergo slight deformation, which can prevent the rotating assembly 13 from cracking when the connecting rod 11 is squeezed on it. The deformation opening 15 also facilitates the installation or removal of the rotating assembly 13 from the corresponding annular groove 10.

[0043] The upper tube body 2 is provided with a resistance step 16, which is used to increase the lifting resistance of the connector 4 in the connector socket 6 when the engagement ring groove 14 corresponds to the position of the connector hole 7. The diameter of the resistance step 16 is smaller than the diameter of the connector socket 6.

[0044] A chamfered surface is provided at the junction of the upper end of the resistance step 16 and the connection socket 6. The chamfered surface is used to contact the rotating assembly 13 as it descends with the connection plug 4, so that the rotating assembly 13 is locked to the connection plug 4 through the deformation opening 15.

[0045] A filling support 19 is provided between the lower end of the upper tube 2 and the outer sleeve 3. The filling support 19 has an upper sliding hole 20 that slides with the circumference of the upper tube 2 and a lower sliding hole 21 that slides with the circumference of the lower tube 1. The upper sliding hole 20 and the lower sliding hole 21 are connected. The filling support 19 has a mating opening 22 that corresponds to the position of the connecting hole 7 after the filling support 19 is connected to the upper tube 2 and the lower tube 1. The mating opening 22 is clearance-fitted with the connecting rod 11.

[0046] The filling support 19 can play a filling and supporting role when the upper tube 2, lower tube 1, and outer sleeve 3 are assembled, so as to prevent gaps between the upper tube 2, lower tube 1, and outer sleeve 3.

[0047] A positioning block 23 is provided on the lower tube body 1, and a positioning groove 24 is provided on the filling support 19 for engaging with the positioning block 23 when the filling support 19 is sleeved on the upper tube body 2 and the matching opening 22 corresponds to the connecting hole 7.

[0048] When the filling support 19 is assembled onto the upper tube 2, the positions of the positioning block 23 and the positioning groove 24 are observed and engaged, so that the positions of the mating opening 22 and the connecting hole 7 correspond, thereby achieving the positioning effect between the connecting hole 7 and the mating opening 22.

[0049] The upper end face of the upper tube 2 has a spring cavity 25 for installing the spring.

[0050] A support crossbar 26 is provided on the side end face of the outer sleeve 3. One end of the support crossbar 26 is connected to the outer sleeve 3, and the other end of the support crossbar 26 is provided with a support sleeve 27. A connecting hole is provided on the outer sleeve 3 for inserting the support crossbar 26, and a corresponding connecting hole is provided on the support sleeve 27 for inserting the other end of the support crossbar 26. During assembly, the support crossbar 26 is first inserted into the connecting hole of the outer sleeve 3 and then welded to fix it. Then, the other end of the support crossbar 26 is inserted into the connecting hole of the support sleeve 27 and welded to fix it.

[0051] The working principle of this utility model is as follows: After the lower pipe body 1, upper pipe body 2, and outer sleeve 3 are manufactured, the connector 4, which connects to the outlet pipe 5, is first inserted into the connecting hole 6 until the corresponding annular groove 10 corresponds to the position of the connecting hole 7. Then, the lower end of the upper pipe body 2 is fitted onto the upper end of the lower pipe body 1 for connection, ensuring that the corresponding opening 8 corresponds to the connection position. Next, the outer sleeve 3 is fitted onto the outside of the upper pipe body 2, ensuring that the outer opening 9 corresponds to the position of the connecting hole 7. Subsequently, the connecting rod 11 is inserted into the outer opening 9, the connecting hole 7, the corresponding opening 8, and the corresponding annular groove 10, and then... The connecting rod 11 is fixed between the lower pipe body 1, the upper pipe body 2, and the outer sleeve 3 by the fastener. One end of the connecting rod 11 is fitted with the corresponding annular groove 10 to restrict the lifting and lowering of the connecting plug 4 in the connecting socket 6, and to allow the connecting plug 4 to rotate in the connecting socket 6, thereby realizing the rotation effect of the water outlet pipe 5 and preventing the water outlet pipe 5 with the connecting plug 4 from detaching from the upper pipe body 2. The lower pipe body 1, the upper pipe body 2, the outer sleeve 3, the connecting plug 4, and the water outlet pipe 5 can be assembled and fixed at one time without the need for welding and fixing of accessories, which can further reduce production and assembly costs.
