Description

Technical Field

[0001] The utility model relates to a faucet structure in the field of sanitary ware, in particular to a pop-up prevention structure in which a valve core seat and a buckle ring cooperate. Background Art

[0002] At present, there are many ways to install the water outlet pipe on the market. One of them is to set a pressing hole on the side wall of the water outlet pipe, and the pressing hole cooperates with the protruding pressing block on the outer wall of the inner buckle to fix the circumferential position of the water outlet pipe. However, the existing water outlet pipe and the buckle are only limited by the pressing block, which has poor stability. The buckle and the valve core seat are in a movable sleeve connection form. The pressing block on the buckle can be pressed 360 degrees on the buckle body without a restrictive protection structure. When there is wear after long-term use, the pressing block is easy to detach from the pressing hole, and the limit between the water outlet pipe and the buckle is lost. When the water pressure is too high, the water outlet pipe is easily flushed out; or because the gap between the buckle and the water outlet pipe is large, when the water pressure in the water outlet pipe is too high, the pressing block is also easy to be squeezed out of the pressing hole under the impact force and randomly ejected.

[0003] It can be seen from this that there is a large gap between the existing valve core seat and the buckle ring, and between the buckle ring and the water outlet pipe, because the pressing block can be pressed 360 degrees along the valve core seat and is easy to detach from the pressing hole, and the gap between the buckle ring and the inner wall of the water outlet pipe is poor. The stability of this limiting structure is poor, and the water outlet pipe is prone to being ejected, which not only affects the use, but also makes it time-consuming and laborious to replace parts, giving users a bad experience. Utility Model Content

[0004] The utility model aims at the technical defects mentioned in the background technology and provides an anti-pop-out structure in which a valve core seat and a buckle ring cooperate.

[0005] The technical solution adopted by the utility model is: a valve core seat and a buckle ring cooperate with an anti-pop-out structure, which is installed in a water outlet pipe and cooperates with the water outlet pipe, and comprises a valve core seat and a buckle ring.

[0006] The clamping column in the upper middle part of the valve core seat comprises a clamping column body, reinforcing ribs and a clamping groove; a plurality of reinforcing ribs are distributed along the outer circumference of the clamping column body, and a clamping groove is formed between adjacent reinforcing ribs;

[0007] The buckle ring is sleeved outside the clamping column and comprises a buckle ring body, a pressing block and ribs; the pressing block corresponds to the clamping groove; and a plurality of ribs are distributed along the outer circumference of the buckle ring body.

[0008] As a preferred technical solution: the pressing block passes through the pressing hole on the side wall of the water outlet pipe to achieve positioning.

[0009] As a preferred technical solution: the rib is a wedge-shaped protrusion that is thin on the top and thick on the bottom.

[0010] As a preferred technical solution: the distance from the outer edge of the reinforcing rib to the wall of the water outlet pipe is smaller than the thickness of the pressing block.

[0011] As a preferred technical solution: the distance from the bottom of the slot to the wall of the water outlet pipe is greater than the thickness of the pressing block.

[0012] Compared with the prior art, the utility model has the following technical effects:

[0013] 1. The utility model improves the clamping column part in the middle and upper part of the valve core seat into a reinforcing rib and a clamping groove structure. The clamping groove position can realize that the pressing block on the buckle ring is separated from the pressing hole when pressed, and the reinforcing rib position can support the pressing block to prevent it from being separated from the pressing hole, which plays a role in ensuring the positioning of the pressing block and effectively preventing the pressing block from being separated;

[0014] 2. In the solution disclosed by the utility model, a number of ribs are added to the outside of the buckle to reduce the gap between the inner wall of the water outlet pipe and the buckle, avoid the water outlet pipe from swinging, improve the stability of the connection, and effectively avoid the water outlet pipe from being ejected when the water pressure increases.

[0021] In the figure: water outlet pipe 1, valve core seat 2, retaining ring 3.

[0022] Among them: the valve core seat includes a valve core seat body 2-1, a clamping groove 2-2, a reinforcing rib 2-3, and a clamping column body 2-4; the buckle ring includes a buckle ring body 3-1, a pressing block 3-2, and a rib 3-3. DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] See attached Figure 1-6The valve core seat and buckle ring cooperate with the anti-pop-up structure disclosed in the utility model and are installed in the water outlet pipe 1, and cooperate with the water outlet pipe 1, including a valve core seat 2 and a buckle ring 3. The clamping column in the upper middle part of the valve core seat body 2-1 includes a clamping column body 2-4, a reinforcing rib 2-3 and a clamping groove 2-2. The reinforcing rib 2-3 is longitudinally arranged, and one side thereof is fixedly connected to the clamping column body 2-4. A plurality of reinforcing ribs 2-3 are distributed along the outer circumference of the clamping column body 2-4. A clamping groove 2-2 is formed between adjacent reinforcing ribs 2-3. The distance from the outer edge of the reinforcing rib 2-3 to the wall of the water outlet pipe is less than the thickness of the pressing block. The distance from the bottom of the clamping groove 2-2 to the wall of the water outlet pipe is greater than the thickness of the pressing block. When the pressing block 3-2 is pressed or subjected to impact force, the slot position can enable the pressing block to fall into and then detach from the pressing hole; the outer side of the reinforcing rib can support the pressing block to prevent it from detaching from the pressing hole, thereby ensuring the positioning of the pressing block and effectively preventing the pressing block from detaching. As a preferred solution, the thickness of the reinforcing rib can match the width of the pressing block.

[0025] The buckle ring 3 is sleeved on the outside of the clamping column of the valve core seat 2, and includes a buckle ring body 3-1, a pressing block 3-2 and ribs 3-3. The pressing block 3-2 corresponds to the clamping groove 2-2; and a plurality of ribs 3-3 are distributed along the outer circumference of the buckle ring body.

[0026] As a preferred embodiment, the rib 3 - 3 is a protrusion of a wedge-shaped structure that is thin at the top and thick at the bottom.

[0027] During installation and use, install the retaining ring 3 on the valve core seat 2, then install the sealing ring, and then install the water outlet pipe 1 on the valve core seat 2, so that the retaining ring 3 plays a positioning role, and the ribs on the retaining ring 3 play a role in reducing the swing clearance of the water outlet pipe. On the premise of meeting the product requirements, the strength of the retaining ring 3 will not rebound when the water pressure is too high, preventing the water outlet pipe from rushing out, and it is effective whether the handle is on the left or right side.
