Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a faucet assembly that is convenient for disassembling and assembling a valve core seat. Background Art

[0002] The faucet body structure primarily comprises the faucet body, valve core, valve body assembly, and gland. The faucet body, also known as the three-way body, forms a vertical channel with upper and lower openings, as well as a transverse channel intersecting and connecting the vertical channel for mounting the valve core. The valve body assembly comprises a valve core seat that connects and mounts corresponding fluid pipes. The conventional installation method for faucet bodies primarily involves first inserting the valve core seat, with the fluid pipe mounted, into the faucet body through the lower opening. Because the front end of the valve core seat is a complete disc, the inclination angle of the valve core seat must be appropriately adjusted to engage the front end of the valve core seat within the transverse channel. The seat is then secured relative to the faucet body via screws.

[0003] However, when the distance H between the center line of the transverse channel and the bottom end surface of the faucet body reaches a certain level, interference will occur between the fluid tube of the valve core seat and the faucet body, making it difficult for the front end of the valve core seat to be inserted into the valve core installation, making this installation method impossible to assemble.

[0004] The existing valve body assembly has problems such as low installation efficiency and difficult operation process. Moreover, when the valve core seat and the fluid pipe are an integrated structure and the fluid pipe is constructed as a non-flexible part, the valve core seat cannot be installed into the horizontal channel from the vertical channel side of the faucet body, resulting in failure to meet the installation requirements of such a structure, and effective installation and application cannot be achieved.

[0005] Therefore, the research purpose of the present invention is to design a faucet assembly that is simple in structure, easy to assemble, low in cost, and has stable and reliable performance and is easy to disassemble and assemble the valve core seat. Utility Model Content

[0006] In view of the technical problems existing in the above-mentioned prior art, the present invention provides a faucet assembly that is easy to disassemble and assemble the valve core seat. The faucet assembly that is easy to disassemble and assemble the valve core seat can effectively solve the technical problems existing in the above-mentioned prior art.

[0007] The technical solution of the utility model is:

[0008] A faucet assembly that facilitates the assembly and disassembly of a valve core seat, comprising: a faucet body, a valve core, a valve body assembly, and a gland; the valve body assembly includes a valve core seat and a fluid tube connected to the valve core seat; the valve core seat is detachably fixedly mounted on the inner end of a transverse channel of the faucet body; the valve core is mounted in the transverse channel of the faucet body, and the gland is installed and fixed to the valve core by threaded connection; a corresponding ridge is fixedly connected to the end of the transverse channel of the faucet body where the valve core seat is mounted; the faucet assembly further comprises:

[0009] A connecting mechanism is used to detachably and fixedly connect the valve core seat and the faucet body, and the connecting mechanism includes a connecting piece and a locking piece; when the valve core seat is installed, the connecting piece is sleeved on the outer side of the valve core seat and abutted between the ridge and the disc of the valve core seat, and the locking piece is installed in the transverse channel by means of a threaded connection and pressed on the outer side of the disc of the valve core seat, so that the valve core seat is detachably and fixedly installed on the faucet body.

[0011] The circumferential arc surface of the disc is inwardly recessed to form a circle of annular arc grooves for mounting the connector; when the connector is mounted on the valve core seat, the connector protrudes outward from the annular arc groove.

[0012] The outer side wall edge of the convex edge is provided with a positioning shoulder for embedding the connecting piece, and the positioning shoulder is provided in a plane shape or an arc surface shape.

[0013] The connecting piece is composed of an arc-shaped retaining ring or a plurality of arc-shaped retaining bars detachably installed in the annular arc groove, and the arc-shaped retaining ring or arc-shaped retaining bars are made of elastic stainless steel.

[0014] A notch for disassembling the arc-shaped retaining ring is provided in the circumferential edge of the disk, and the notch penetrates the outer circular side wall of the disk outward.

[0015] The locking piece includes a pressing part and a connecting part that are integrally formed inside and outside. The outer surface of the connecting part is evenly distributed with external threads that are compatible with the transverse channel. The outer side surface that is not connected to the pressing part is recessed inward and has several positioning grooves at intervals. When the locking piece is installed, the pressing part abuts against the outer circular side wall of the disc.

[0016] A positioning mechanism is provided between the valve core seat and the transverse channel for assembling, positioning and limiting the rotation of the valve core seat. The positioning mechanism includes a positioning boss extending radially from the convex edge or fixed to the valve core seat, and a groove concavely provided on the corresponding edge of the disc or on the corresponding inner wall of the convex edge. The groove runs through the inner and outer circular side walls of the disc.

[0017] The faucet assembly also includes an O-ring for leak prevention.

DETAILED DESCRIPTION

[0035] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the following embodiments and accompanying drawings:

[0036] Example 1

[0037] refer to Figure 1-7 A faucet assembly that facilitates the assembly and disassembly of a valve core seat comprises a faucet body 1, a valve core 2, a valve body assembly 3, and a gland 4. The valve body assembly 3 includes a valve core seat 301 and a fluid tube 302 connected to the valve core seat 301. The valve core seat 301 is detachably fixedly mounted on the inner end of a transverse channel 102 of the faucet body 1. The valve core 2 is mounted in the transverse channel 102 of the faucet body 1. The gland 4 is installed and secures the valve core 2 by threaded connection. The inner end of the transverse channel 102 of the faucet body 1 is fixedly connected to a corresponding ridge 5. The faucet assembly further comprises:

[0038] The connecting mechanism is used for detachably and fixedly connecting the valve core seat 301 and the faucet body 1, and the connecting mechanism includes a connecting piece 6 and a locking piece 7; when the valve core seat 301 is installed, the connecting piece 6 is sleeved on the outer side of the valve core seat 301 and abutted between the ridge 5 and the disc 3011 of the valve core seat 301, and the locking piece 7 is installed in the transverse channel 102 by threaded connection and pressed on the outer side of the disc 3011 of the valve core seat 301, so that the valve core seat 301 is detachably and fixedly installed on the faucet body 1.

[0039] The faucet assembly is further provided with a corresponding handle 12 at the outer end of the transverse channel 102 of the faucet body 1 , and the handle 12 is connected to the valve core 2 for controlling the opening and closing of the faucet assembly.

[0040] The convex edge 5 is formed by extending the transverse channel 102 of the faucet body 1 in the radial direction as a whole.

[0041] The diameter of the disc 3011 is smaller than the inner diameter of the flange 5; when the connecting member 6 is installed, the distance between its outer end and the center line of the transverse channel 102 is greater than the inner diameter of the flange 5, and the distance between its inner end and the center line of the transverse channel 102 is smaller than the diameter of the disc 3011.

[0042] The circumferential arc surface of the disc 3011 is inwardly recessed to form a circle of annular arc grooves 3012 for mounting the connector 6 ; when the connector 6 is mounted on the valve core seat 301 , the connector 6 protrudes outward from the annular arc groove 3012 .

[0043] The outer wall edge of the protruding edge 5 is provided with a positioning shoulder 501 for embedding the connecting member 6 , and the positioning shoulder 501 is provided in a plane or arc shape.

[0044] The connecting member 6 is composed of an arc-shaped retaining ring that is detachably installed in the annular arc groove 3012, and the arc-shaped retaining ring is made of elastic stainless steel.

[0045] The present invention utilizes a connection mechanism comprised of a connector 6 and a locking member 7 for rapid assembly and disassembly of the valve body assembly 3 and the faucet body 1. First, by setting the diameter of the disc 3011 smaller than the inner diameter of the flange 5 at the inner end of the transverse channel 102, the valve core seat 301 of the valve body assembly 3 can quickly and conveniently enter from the longitudinal channel 101 and extend into the transverse channel 102. The disc 3011 is then pushed past the positioning shoulder 501. Secondly, the connector 6 is inserted into the disc 3011, leveraging its inherent elasticity to engage within the annular arc groove 3012. The disc 3011 is then pushed in the opposite direction, engaging the connector 6 and abutting the positioning shoulder 501. Finally, the locking member 7, threadedly screwed into the transverse channel 102, presses the disc 3011, forcing the connector 6 between the flange 5 and the disc 3011, thereby securing the valve assembly. On the basis of ensuring the practical performance of the faucet assembly, the utility model has a simpler structure, is more convenient to assemble, and has stable and reliable performance.

[0046] A notch 3013 for disassembling the arc-shaped retaining ring is provided in the circumferential edge of the disk 3011 , and the notch 3013 extends outward through the outer circumferential side wall of the disk 3011 .

[0047] The connector 6 of the present invention utilizes a non-closed-loop arcuate retaining ring or a plurality of spaced arcuate retaining bars, allowing the arcuate retaining ring to expand with its own elasticity and cooperate with a tool for easy installation on the disc 3011. Furthermore, a notch 3013 is provided in the disc 3011. For disassembly, the valve body assembly 3 can be quickly and easily removed by simply rotating the locking member 7 in the opposite direction, engaging the tool in the notch 3013 to disengage the arcuate retaining ring from the valve core seat 301, and then pushing the valve core seat 301 into the transverse passage 102.

[0048] The locking member 7 comprises a press-fit portion 701 and a connecting portion 702, which are integrally formed inside and outside. The outer surface of the connecting portion 702 is evenly distributed with external threads that mate with the transverse channel 102. The outer surface of the connecting portion 702, which is not connected to the press-fit portion 701, is recessed inward and has a plurality of retaining grooves 703 at intervals. When the locking member 7 is installed, the press-fit portion 701 abuts the outer circumferential sidewall of the disc 3011. The retaining grooves 703, when used with a tool, facilitate easy assembly and disassembly of the locking member 7.

[0049] A positioning mechanism is provided between the valve core seat 301 and the transverse passage 102 for positioning and limiting the rotation of the valve core seat 301. This positioning mechanism comprises a positioning boss 8 extending radially from the ridge 5, and a recessed groove 9 formed on the corresponding edge of the disc 3011. The recess 9 extends through both the inner and outer circular sidewalls of the disc 3011. The present invention utilizes the cooperation of the positioning boss 8 and recess 9 to circumferentially limit the valve body assembly and the connector 6.

[0050] Example 2

[0051] refer to Figure 8-11 The difference between this embodiment and the first embodiment is that the faucet assembly further includes an O-ring 10 for leak prevention, and the circumferential arc surface of the disc 3011 is inwardly recessed to provide a second annular arc groove 3014 located inside the annular arc groove 3012; when the valve core seat 301 is installed, the O-ring 10 is squeezed and installed between the second annular arc groove 3014 and the convex edge 5.

[0052] The present invention incorporates an O-ring 10 without compromising ease of installation. By pre-installing the O-ring 10 on the disc 3011 of the valve core seat 301 before installing the valve body assembly 3, this effectively prevents leaks caused by a mismatched valve core 2, further enhancing the faucet's sealing performance. Compared to conventional faucets where the valve body assembly 3 cannot be fitted with a sealing ring, the present invention facilitates quick and easy installation of the O-ring 10. Furthermore, the provision of the O-ring 10 does not adversely affect the ease of installation of the valve body assembly 3, ensuring its practical performance.

[0053] The faucet body 1 is provided with a corresponding connecting and paving groove 11 extending from the longitudinal channel 101 to the convex edge 5; the setting of the connecting and paving groove 11 can effectively prevent the O-ring 10 from being scratched during installation and promote the smooth installation of the valve body assembly 3 with the O-ring 10.

[0054] A positioning mechanism is provided between the valve core seat 301 and the transverse passage 102 for positioning and limiting the rotation of the valve core seat 301. The positioning mechanism comprises a positioning boss 8 fixed to the valve core seat 301 and a groove 9 recessed into the inner sidewall of the corresponding ridge 5. The positioning boss 8, which circumferentially limits the valve body assembly 3, is provided on the valve core seat 301 to facilitate the installation of the O-ring 10.

[0055] It should be noted that the implementation principle and technical effects of this embodiment are the same as those of the first embodiment. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding contents in the first embodiment.

[0056] Example 3

[0057] This embodiment differs from the first embodiment in that the connector 6 is composed of a plurality of spaced arcuate bars removably mounted within the annular arc groove 3012. The arcuate bars are made of resilient stainless steel. Furthermore, the annular arc groove 3012 is divided into corresponding sub-slots by integrally formed partitions, and the arcuate bars are embedded in the corresponding sub-slots. By configuring the connector 6 as a plurality of arcuate bars, the valve body assembly can be easily disassembled by simply detaching one arcuate bar from the valve core seat 301, facilitating the removal and replacement of the connector 6.

[0058] It should be noted that the implementation principle and technical effects of this embodiment are the same as those of the first embodiment. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding contents in the first embodiment.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
