[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0025] like Figures 1-5 As shown, an anti-expansion shower faucet includes a faucet housing 101, an installation port 102 on the faucet housing 101, an inner valve core 103 disposed within the faucet housing 101 through the installation port 102, a first water outlet 104 on the faucet housing 101, a valve core mounting seat 105 on the faucet housing 101, a main valve core (not shown in the figure) disposed between the valve core mounting seat 105 and the inner valve core 103, and a valve core cover (not shown in the figure) locked on the valve core mounting seat 105. The faucet housing 101 is also provided with an anti-expansion device to prevent the faucet housing 101 from expanding under force.
[0026] To prevent the faucet housing 101 from expanding on the upper and lower sides, affecting its sealing performance and service life, the anti-expansion device includes: at least two reinforcing ribs 106 disposed inside the faucet housing 101 and located on the upper and lower sides of the housing respectively, and a locking block 107 disposed at the end of the reinforcing rib 106 and located on the side away from the housing, and a tensioning device is provided between the locking blocks 107.
[0027] In order to bring the upper and lower sides of the faucet housing 101 together, the tensioning device includes a pull plate 108, which covers the reinforcing ribs 106 and has a locking hole 109 corresponding to the locking block 107. The pull plate 108 is made of metal to improve the strength of the pull plate 108 itself and prevent deformation.
[0028] To improve strength and distribute stress, the reinforcing rib 106 consists of four ribs.
[0029] To facilitate the installation of the inner valve core 103 and improve its strength, the inner valve core 103 includes: a main valve seat 110, an inlet pipe 111 and an outlet pipe 112 disposed on the main valve seat 110, and an inlet seat 113 disposed on the inlet pipe 111; the inner valve core 103 is also provided with several crisscrossing reinforcing plates 114, and the reinforcing plates 114 are provided with positioning grooves 115 that match the reinforcing ribs 106.
[0030] To enhance the functionality of the faucet and provide multiple water outlets for various uses, the inner valve core 103 is also equipped with a water distribution valve seat 116. The faucet housing 101 has a water distribution valve core mounting port 117 corresponding to the water distribution valve seat 116 and a second water outlet 118. The water outlet pipe 112 is connected to the water distribution valve seat 116. The water distribution valve seat 116 is equipped with a water distribution port 119 corresponding to the second water outlet 118. A water distribution pipe 120 is also provided between the water distribution valve seat 116 and the main valve seat 110. An extension pipe 121 is provided between the water distribution pipe 120 and the first water outlet 104 through a fixing device.
[0031] The fixing device includes: a slot 122 inclinedly opened on the main valve seat 110; a connecting hole 123 opened on the slot 122 for communicating with the extension tube 121; a retaining plate 124 provided on the extension tube 121; a countersunk hole 125 opened on the slot 122 to cooperate with the retaining plate 124; a sealing groove 126 opened between the countersunk hole 125 and the retaining plate 124; and a U-shaped plug 127 inserted into the slot 122, with one end abutting against the main valve seat 110 and the other end abutting against the retaining plate 124. A positioning device is also provided between the extension tube 121 and the first outlet 104. The upper side of the U-shaped plug 127 abuts against the main valve core provided on the main valve seat 110.
[0032] The positioning device includes: a limiting platform 128 disposed at the water outlet end of the extension pipe 121, a limiting ring platform 129 disposed on the first water outlet 104, a clearance groove 130 on the limiting ring platform 129 for avoiding the connecting pipe, a connecting thread (not shown in the figure) disposed on the first water outlet 104, and an aerator (not shown in the figure) locked on the connecting thread and the aerator abutting against the limiting platform 128.
[0033] To prevent the faucet housing 101 from being further equipped with a positioning post 131, the reinforcing plate 114 is provided with a positioning sleeve 132 that matches the positioning post 131.
[0034] To facilitate the installation of the inner valve core 103 inside the faucet housing 101, the reinforcing rib 106 is gradually inclined from the inside to the outside of the housing.
[0035] To save internal space in the faucet housing 101 and make it more compact, the reinforcing plate 114 is also provided with a groove 133 to facilitate the installation of the pull plate 108.
[0036] To protect the faucet and prevent the pull plate 108 from detaching, a cover plate 134 is also provided on the inner valve core 103 to enhance aesthetics and prevent the pull plate 108 from detaching.
[0037] Working principle: During assembly, the inner valve core 103, the alignment positioning post 131, and the reinforcing rib 106 are inserted into the faucet housing 101. Then, the extension tube 121 is inserted from the side of the first outlet 104, abutting against the countersunk hole 125. The U-shaped insert 127 is then inserted into the slot 122. Next, the pull plate 108 is placed on the locking block 107 of the reinforcing rib 106, and the cover plate 134 is locked onto the inlet seat 113, completing the installation of the pull plate 108. Finally, the main... The valve core is set on the main valve seat 110, which completes the positioning of the inner valve core body 103 and the faucet housing 101. When installing the main valve core, the user turns the valve core cover to generate pressure on the main valve core, thereby positioning it on the main valve seat 110 and the valve core mounting seat 105. At this time, due to the presence of the pull plate 108, the faucet housing 101 will not deform after being subjected to force. And because it cannot generate large deformation, the valve core cover will become difficult to turn after being locked in place, thereby preventing over-installation.
[0038] When in use, when fluid flows from the main valve seat 110 to the main valve core and then through the main valve core to the outlet pipe 112, a relatively large water pressure is generated. However, due to the presence of the pull plate 108, even if the water pressure is too high, it will not cause the faucet housing 101 to expand up and down, thus affecting the sealing between the main valve core and the main valve seat 110 and causing leakage.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions above are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
