Description

An Elastic Positioning Structure for Preventing Axial Movement of a Rotary Faucet

technical field

The utility model relates to the field of bathrooms, in particular to a rotary water tap.

Background technique

The kitchen faucet or other faucets in the bathroom faucet require that the outlet pipe must be able to rotate because of its use, and when the outlet pipe is rotated, it must be sealed and reliable, and it is easy to install and use smoothly.

The O-shaped rubber ring seal and upper insertion installation method commonly used in the production and manufacture of the above-mentioned rotary faucets in the industry have basically solved the problems of sealing the water outlet pipe and facilitating installation, but the use of different rotating structures is firm in structure and smooth in use. There is a big difference in the aspect, Fig. 1 shows the installation and positioning structure of the existing rotary faucet, specifically referring to Fig. 1 and Fig. 2, including the main body of the faucet 1' and the outlet pipe which is movably inserted on the main body of the faucet 1' 2', the outlet pipe 2' is sleeved with a lock nut 20' that can be connected to the external thread on the faucet body 1', and a lock nut 20' is arranged between the outlet pipe 2' A plastic positioning sleeve 21' sleeved on the water outlet pipe 2', a plastic snap ring 22' sleeved on the water outlet pipe 2' is provided between the plastic positioning sleeve 21' and the upper end of the faucet main body 1', and On the side wall of the water outlet pipe 2', there is also a card slot that is engaged with the plastic snap ring 22'. Using the above-mentioned structure, the plastic snap ring 22' is compressed by the lock nut 20' and the plastic positioning sleeve 21', In this way, the outlet pipe 2', which is engaged with the plastic snap ring 22', is fixedly installed on the faucet body 1' without being separated upward. However, if the outlet pipe 2' is lifted upwards, the plastic snap ring 22' will be squeezed The pressure deforms and slides into the assembly gap reserved between the outlet pipe 2' and the faucet main body 1', and cannot normally press the outlet pipe 2' on the faucet main body 1', so the outlet pipe 2' will axially shift. moving situation.

As an improvement of the above technical solution, the outer wall of the elastic positioning sleeve is also provided with a screw positioning groove used in cooperation with the set screw.

As a further improvement of the above technical solution, the middle and lower part of the insertion end of the water outlet pipe inserted into the main body of the faucet is sleeved with a sealing ring located between the outer wall of the water outlet pipe and the cavity wall of the main body of the faucet.

Further, a concave groove is provided at the end of the insertion end of the water outlet pipe inserted into the main body of the faucet, and an auxiliary positioning sleeve abutted against the cavity wall of the main body of the faucet is set in the concave groove.

The beneficial effect of the utility model is: because the utility model is provided with a positioning groove on the insertion end where the water outlet pipe is inserted into the main body of the faucet, the positioning groove is provided with an elastic positioning sleeve, and the pressure is pressed by tightening the set screw arranged on the main body of the faucet. Tighten the elastic positioning sleeve so that the water outlet pipe is fixedly installed on the main body of the faucet to prevent axial movement.

Detailed ways

Referring to Figures 3 to 6, an elastic positioning structure for preventing axial movement of a rotary faucet includes a faucet body 1 with a built-in cavity and an outlet that is movably inserted in the cavity of the faucet body 1 and can rotate relative to it. The water pipe 2, the upper part of the insertion end of the water outlet pipe 2 inserted into the faucet main body 1 is provided with a positioning groove 20, and an elastic positioning sleeve 3 with an interference fit is set in the positioning groove 20, that is, the aperture of the elastic positioning sleeve 3 is larger than the The diameter of the water pipe 2 should be slightly smaller. When the elastic positioning sleeve 3 is socketed and installed in the positioning groove 20 of the water outlet pipe 2, the outlet pipe 2 will slightly expand the elastic positioning sleeve 3, but the water outlet pipe 2 can still be relatively elastic. The positioning sleeve 3 rotates, and the elastic positioning sleeve 3 is provided with an opening 30 that is convenient for it to be inserted into the positioning groove 20. At the same time, the inner wall and the outer wall of the elastic positioning sleeve 3 are evenly provided with a plurality of variable grooves 31. The main body 1 of the faucet is also provided with a set screw 10 for compressing the elastic positioning sleeve 3 to prevent its axial movement. By tightening the set screw 10, the elastic positioning sleeve 3 is compressed so that the elastic positioning sleeve 3 cannot move up and down. , so as to indirectly lock and wear the outlet pipe 2 in the elastic positioning sleeve 3 to prevent the axial movement of the outlet pipe 2; when the elastic positioning sleeve 3 is installed in the positioning groove 20, the outlet pipe 2 is sleeved with elastic positioning The position of the sleeve 3 is in a slight clearance fit or a slight transition fit state relative to the cavity of the faucet body 1. If the outlet pipe 2 is plugged and installed in the faucet body 1, the outer wall and the inner wall of the elastic positioning sleeve 3 are evenly opened. There are multiple variable slots 31 so that when the outlet pipe 2 is inserted into the main body 1 of the faucet, the elastic positioning sleeve 3 can be slightly deformed so that the elastic positioning sleeve 3 is close to the cavity wall of the main body 1 of the faucet. There is no radial gap between the water pipe 2 and the main body 1 of the faucet, and there is no need to use a high-precision production process to process the elastic positioning sleeve 3, which helps to reduce production costs. In addition, when the water outlet pipe 2 is inserted into the main body 1 of the faucet, if There is a slight gap between the outlet pipe 2 and the main body of the faucet 1, and the elastic positioning sleeve 3 can be squeezed by slightly tightening the set screw 10, so that the elastic positioning sleeve 3 is deformed, thereby tightening the gap between the outlet pipe 2 and the main body of the faucet 1 , which helps to eliminate the radial gap between the water outlet pipe 2 and the main body 1 of the faucet.

Furthermore, in order to facilitate the production and installation of the rotary faucet, the outer wall of the elastic positioning sleeve 3 is also provided with a screw positioning groove 32 used in conjunction with the set screw 10 .

Furthermore, in order to ensure the sealing performance of the rotary faucet and ensure that no leakage occurs when it rotates, the middle and lower part of the insertion end of the outlet pipe 2 inserted into the faucet main body 1 is sleeved with a joint located on the outer wall of the water outlet pipe 2 and the faucet main body 1. A sealing ring 21 between the chamber walls.

Further, in order to prevent the water outlet pipe 2 from being inclined when inserted into the faucet body 1, a recessed groove 22 is provided at the end of the insertion end of the water outlet pipe 2 inserted into the faucet body 1, and a recessed groove 22 is fitted with a faucet body 1 The auxiliary positioning sleeve 4 abutted against the wall of the cavity is installed on both ends of the outlet pipe 2 through the auxiliary positioning sleeve 4 and the elastic positioning sleeve 3 respectively, which reduces the swing angle of the positioning structure, forms anti-tilt double positioning, and minimizes the outlet pipe 2 to enhance the radial stability of the water outlet pipe 2.

The above descriptions are only the preferred implementation modes of the present utility model, as long as the technical solutions that achieve the purpose of the utility model by basically the same means all fall within the scope of protection of the utility model.
