Description

Technical Field

[0001] This utility model belongs to the field of valve core technology, and specifically relates to a valve core mounting mechanism. Background Technology

[0002] Chinese Patent CN217842778U discloses a structurally improved lead-free faucet, including a shell, a valve core seat, a valve core body, a water outlet hose, and a handle. The shell has a main body and an extension rod. The extension rod extends horizontally outward from the top of the main body and has a cavity. The valve core seat is recessed within the main body, and the valve core body is placed inside the cavity of the valve core seat. The water outlet hose is built into the cavity, with one end connected to the water outlet channel and the other end exposed at the end of the cavity. By directly providing a cavity in the valve core seat to accommodate the valve core body, and providing a sealing device at the top opening of the cavity near the inner wall of the valve core body, the water outlet cavity formed between the valve core seat and the valve core body is located below the sealing device, forming an upper water seal. This allows the valve core seat and the valve core body to be recessed and built into the main body together, thereby enabling a smooth connection between the water outlet channel of the valve core seat and the water outlet hose.

[0003] The above technical solution has the following drawbacks: the valve core seat of this type of faucet is recessed into the housing body, while the valve core body is built into the cavity of the valve core seat. A gland threaded to the housing body holds the valve core body in place to limit its movement, thereby ensuring stable assembly of the valve core body and the valve core seat. This means that the valve core seat requires a cavity for the valve core body to be housed within in order to cooperate with the gland and achieve stable assembly of the valve core body and the valve core seat. This assembly method leads to an increase in the consumption of valve core seat materials, thereby increasing production costs. Without a cavity for the gland to be installed, this assembly method cannot even achieve stable assembly of the valve core body and the valve core seat, limiting its applicability. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a valve core mounting mechanism. The technical problem to be solved by this utility model is: how to reduce production costs.

[0005] The above-mentioned technical objective of this utility model can be achieved through the following technical solution: a valve core mounting mechanism, including a valve seat, a valve core, a fastener and a limiting plate, wherein the valve seat is provided with a mounting plane, the valve core is placed on the mounting plane, the limiting plate is placed on the valve core, and the fastener presses the limiting plate on the valve core and connects it to the valve seat, so that the limiting plate and the valve seat cooperate to clamp the valve core.

[0006] In the valve core mounting mechanism described above, there are several fasteners that are evenly distributed along the circumference of the valve core.

[0007] In the aforementioned valve core mounting mechanism, the fastener includes a bolt, which passes through the limiting plate and is threadedly connected to the valve seat, with the head of the bolt abutting against the surface of the limiting plate.

[0008] In the aforementioned valve core mounting mechanism, a through hole is provided on the limiting plate, and a threaded portion is provided on the valve seat. The diameter of the through hole is smaller than the head diameter of the bolt, and the bolt passes through the through hole and is threadedly connected to the threaded portion.

[0009] In the valve core mounting mechanism described above, the valve core is provided with an eccentric positioning protrusion, and the limiting plate is provided with a positioning hole, through which the positioning protrusion passes.

[0010] In the valve core mounting mechanism described above, the limiting plate has a reinforcing protrusion corresponding to the fastener.

[0011] In the valve core mounting mechanism described above, the valve core has a groove corresponding to the fastener, and the fastener passes through the groove.

[0012] In the valve core mounting mechanism described above, a housing is fitted around the outside of the valve core, and the end of the housing abuts against the valve seat.

[0013] In the valve core mounting mechanism described above, a limiting protrusion is provided on the valve seat, and the sidewall of the limiting protrusion abuts against the inner sidewall of the housing.

[0014] In the aforementioned valve core mounting mechanism, a decorative cover is fitted onto the outer wall of the housing, and a mounting hole is provided on the valve seat.

[0015] In summary, the beneficial effects of this utility model compared to the prior art are as follows:

[0016] During the assembly of the valve core and valve seat, the valve core is placed on the mounting plane, and the limiting plate is placed on the valve core. The limiting plate is pressed onto the valve core and connected to the valve seat by fasteners, so that the limiting plate and the valve seat cooperate to clamp the valve core, thereby achieving stable assembly of the valve core and valve seat. This assembly method does not require the addition of a cavity for the built-in valve core, effectively reducing the amount of valve seat consumables and thus reducing the production cost of the valve seat.

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] A valve core mounting mechanism, such as Figures 1-6 As shown, it includes valve seat 1, valve core 2, fastener 5 and limit plate 3.

[0026] A mounting plane 4 is provided on the valve seat 1, and the valve core 2 is placed on the mounting plane 4 to support the valve core 2. A limiting plate 3 is placed on the valve core 2 to support the limiting plate 3. Fasteners 5 press the limiting plate 3 onto the valve core 2 and connect it to the valve seat 1, so that the limiting plate 3 and the valve seat 1 cooperate to clamp the valve core 2, thereby achieving a stable assembly of the valve core 2 and the valve seat 1. It should be noted that in the prior art, the valve core 2 needs a cavity for its internal use to cooperate with the gland and achieve a stable assembly of the valve core 2 and the valve seat 1. However, the assembly method disclosed in this embodiment does not require the addition of a cavity for the internal use of the valve core 2 on the valve seat 1, which effectively reduces the amount of consumables used and thus reduces the production cost of the valve seat 1.

[0027] Preferably, there are several fasteners 5 and they are evenly distributed along the circumference of the valve core 2, so as to ensure uniform force distribution and further guarantee the stable assembly of the valve core 2 and the valve seat 1.

[0028] In this embodiment, the number of fasteners 5 is three. As other options, the number of fasteners 5 can be appropriately increased or decreased, that is, the number of fasteners 5 can be two or four.

[0029] Preferably, the fastener 5 includes a bolt, the shank of which passes through the limiting plate 3 and is threaded to the valve seat 1, and the head of the bolt abuts against the surface of the limiting plate 3, that is, the limiting plate 3 is pressed onto the valve core 2 by the head of the bolt.

[0030] Specifically, the limiting plate 3 has a through hole 6 and the valve seat 1 has a threaded part 7. The diameter of the through hole 6 is smaller than the diameter of the bolt head, that is, the bolt head cannot pass through the through hole 6. The shank of the bolt passes through the through hole 6 and is threaded to the threaded part 7. In this embodiment, the threaded part 7 is a threaded hole. In other solutions, the threaded part 7 is a threaded groove.

[0031] The valve core 2 has a groove 11 corresponding to the fastener 5. The fastener 5 passes through the groove 11, that is, the groove 11 avoids the fastener 5, which can further reduce material consumption and improve the effect of circumferential limiting of the valve core 2.

[0032] The valve core 2 is eccentrically provided with a positioning protrusion 8, and the limiting plate 3 is provided with a positioning hole 9. The positioning protrusion 8 passes through the positioning hole 9, that is, the limiting plate 3 is restricted by the positioning protrusion 8 and cannot rotate or move, thereby achieving the pre-positioning of the limiting plate 3, thus ensuring the relative stability of the limiting plate 3 and the valve core 2. Moreover, when the positioning protrusion 8 passes through the positioning hole 9, it is convenient to align the through hole 6 with the groove 11 and the threaded part 7, so as to facilitate the subsequent installation of bolts and effectively improve the assembly efficiency.

[0033] The limiting plate 3 has a reinforcing protrusion 10 corresponding to the fastener 5. Specifically, the outer side wall of the limiting plate 3 extends outward to form the reinforcing protrusion 10, thereby strengthening the structural strength of the corresponding bolt on the limiting plate 3.

[0034] The outer side of the valve core 2 is fitted with a housing 12. The end of the housing 12 abuts against the valve seat 1. The valve seat 1 is provided with a limiting protrusion 13. The arc-shaped sidewalls at both ends of the limiting protrusion 13 abut against the inner sidewall of the housing 12. The limiting protrusion 13 limits the housing 12, thereby ensuring the stability of the housing 12.

[0035] A decorative cover 14 is fitted on the outer wall of the outer casing 12, and a mounting hole 15 is provided on the valve seat 1, that is, the valve seat 1 can be installed and fixed by screws in conjunction with the mounting hole 15.

[0036] The working principle of this utility model is as follows:

[0037] During assembly, the valve core 2 is placed on the mounting plane 4 of the valve seat 1, the positioning hole 9 is aligned with the positioning protrusion 8, the limiting plate 3 is placed on the upper surface of the valve core 2, and the bolts are passed through the through hole 6 on the limiting plate 3 and the groove 11 on the valve core 2 in sequence. Then the fastener 5 is rotated to make it threadedly connected with the threaded part 7 until the head of the bolt is pressed against the surface of the limiting plate 3, thus completing the stable assembly of the valve core 2 and the valve seat 1.

[0038] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
