Description

TECHNICAL FIELD

[0001] The application relates to the field of faucet connecting structures, in particular to a stamping type connecting structure of a water pipe screw sleeve and a valve body. BACKGROUND

[0002] In the utility model patent with patent application publication No. CN221824527U, a new type of ball valve is introduced, which mainly comprises a main valve body and a valve rod, and the main valve body is used for connecting with a side valve body. The side valve body is actually a screw sleeve used for connecting with a water pipe, so that the water in the water pipe can enter the main valve body. A connecting head is threadedly connected to the main valve body, and the side valve body is pressed and fixed on the main valve body through the connecting head, so as to realize the connection between the main valve body and the side valve body.

[0003] For the related technologies in the above, the inventors find the following defects: 1. The inner cavity space of the side valve body is small, and it is not convenient to tighten the connecting head (which is actually a screw sleeve) on the main valve body by thread connection through a tool, so that the installation of the side valve body is more troublesome; 2. The use of the connecting head as an intermediate connecting piece increases the manufacturing cost of the whole connecting structure. SUMMARY

[0004] In order to facilitate the installation of the side valve body (water pipe screw sleeve) and reduce the manufacturing cost of the connecting structure, the application provides a stamping type connecting structure of a water pipe screw sleeve and a valve body.

[0005] The application provides a stamping type connecting structure of a water pipe screw sleeve and a valve body, which adopts the following technical scheme:

[0006] A stamping type connecting structure of a water pipe screw sleeve and a valve body comprises a main valve body and a water pipe screw sleeve, the end of the main valve body is provided with a positioning flange, the inside of the water pipe screw sleeve is provided with an internal thread, and the end of the water pipe screw sleeve is provided with an abutting inner ring. When the positioning flange is stamping deformed, the positioning flange buckles the abutting inner ring.

[0007] By adopting the above technical scheme, when the water pipe screw sleeve is installed, the water pipe screw sleeve is sleeved on the end of the main valve body, the positioning flange is located inside the water pipe screw sleeve, then the positioning flange is stamping deformed, the positioning flange buckles the abutting inner ring, so that the water pipe screw sleeve and the main valve body are relatively fixed and not easy to be separated. By this stamping forming mode, the quick installation of the water pipe screw sleeve can be realized, and the use of a connecting piece can be saved, thereby reducing the use of materials and the manufacturing cost.

[0008] Optionally, the main valve body is provided with a connecting ring, the positioning flange is located at one end of the connecting ring away from the main valve body, the outer diameter of the connecting ring is smaller than the outer diameter of the main valve body, and the connecting ring is provided with an abutting step for abutting against the abutting inner ring.

[0009] By adopting the technical scheme, the abutting step limits the insertion depth of the water pipe screw in the axial direction, thereby facilitating the subsequent stamping deformation of the positioning flange.

[0010] Optionally, the inner wall of the positioning flange is inclined before the stamping deformation of the positioning flange, and the inner diameter of the positioning flange gradually increases from one end close to the main valve body to the other end.

[0011] By adopting the technical scheme, the positioning flange can be deformed outwardly during the stamping deformation, instead of being deformed inwardly.

[0012] Optionally, the abutting inner ring is provided with a positioning protrusion, and the abutting step is provided with a positioning groove for embedding the positioning protrusion.

[0013] By adopting the technical scheme, the positioning protrusion is embedded in the positioning groove, so that the water pipe screw and the main valve body are not easy to rotate relative to each other, thereby facilitating the subsequent stamping deformation of the positioning flange.

[0014] Optionally, the positioning protrusion is provided with two positioning protrusions, and the positioning groove is also provided with two positioning grooves, and the two positioning protrusions are radially symmetrically arranged.

[0015] By adopting the technical scheme, the water pipe screw and the main valve body are further fixed relative to each other.

[0016] Optionally, the water pipe screw is provided with a sealing gasket, and the sealing gasket covers the positioning flange when the positioning flange is buckled on the abutting inner ring.

[0017] By adopting the technical scheme, the sealing between the water pipe and the water pipe screw and the sealing between the water pipe and the main valve body are better, and the water leakage phenomenon is not easy to occur.

[0018] Optionally, the outer ring of the sealing gasket is provided with an embedding ring, and the positioning flange and the inner side wall of the water pipe screw have an installation gap when the positioning flange is buckled on the abutting inner ring, and the embedding ring is used to embed in the installation gap.

[0019] By adopting the technical scheme, the embedding ring is embedded in the installation gap, thereby further improving the sealing effect.

[0020] To sum up, the present application includes at least one of the following beneficial technical effects:

[0021] 1. When installing the water pipe sleeve, the water pipe sleeve is sleeved on the end of the main valve body, the positioning flange is located inside the water pipe sleeve, and then the positioning flange is stamped and deformed to buckle the abutting inner ring, so that the water pipe sleeve and the main valve body are relatively fixed and not easy to separate. Through this stamping forming mode, the water pipe sleeve can be quickly installed, and the use of a connecting piece can be omitted, thereby reducing the use of materials and manufacturing cost;

[0022] 2. The insertion depth of the water pipe sleeve is limited by the abutting step, and the abutting step limits the axial direction of the water pipe sleeve to facilitate subsequent stamping deformation of the positioning flange;

[0023] 3. The positioning flange can be deformed outward during stamping deformation, rather than inward. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be described in detail in combination with the accompanying Figs. 1-6 The present application will be further described in detail.

[0032] The application discloses a stamping type connecting structure of a water pipe screw sleeve and a valve body.

[0033] With reference to Figs. 1-6 The stamping type connecting structure of the water pipe screw sleeve and the valve body comprises a main valve body 1 and a water pipe screw sleeve 2, and an inner thread 21 is arranged on an inner ring of the water pipe screw sleeve 2 and used for being connected with a water pipe. A valve is arranged in the main valve body 1 and used for controlling water circulation.

[0034] An end of the main valve body 1 is provided with a connecting ring 11, the connecting ring 11 has an outer diameter smaller than that of the main valve body 1, and an abutting step 13 is formed at a connecting position of the connecting ring 11 and the main valve body 1. An abutting inner ring 22 is arranged on the water pipe screw sleeve 2, the abutting inner ring 22 is used for being sleeved on the connecting ring 11, and a positioning flange 12 is arranged at one end of the connecting ring 11. When the abutting inner ring 22 and the water pipe screw sleeve 2 are sleeved on the connecting ring 11, the bottom of the abutting inner ring 22 abuts against the abutting step 13. At this time, the end of the positioning flange 12 is extruded by a stamping device, so that the positioning flange 12 is deformed and buckled on the abutting inner ring 22. At this time, the water pipe screw sleeve 2 and the main valve body 1 are connected with each other.

[0035] Before stamping deformation, the positioning flange 12 is in a whole annular shape, and the inner wall of the positioning flange 12 is arranged to be inclined, that is, the inner diameter of the positioning flange 12 gradually increases from one end close to the main valve body 1 to the other end. Therefore, when the positioning flange 12 is stamped, the positioning flange 12 is ensured to be curved and deformed outwardly instead of being curved and deformed inwardly, so that the stability of the stamping deformation of the positioning flange 12 is ensured.

[0036] Since the abutting inner ring 22 is sleeved on the connecting ring 11 in a sliding mode, there is a certain gap between the abutting inner ring 22 and the connecting ring 11. In order to ensure that the relative positions of the water pipe screw sleeve 2 and the main valve body 1 are more stable during stamping, the bottom of the abutting inner ring 22 is integrally provided with a positioning protrusion 23, and the abutting step 13 is provided with positioning grooves 14 for embedding the positioning protrusion 23, so that the positions of the water pipe screw sleeve 2 and the main valve body 1 are relatively stable, and the stamping deformation of the positioning flange 12 is facilitated. In the embodiment, the positioning protrusion 23 is provided with two, and the corresponding positioning grooves 14 are also provided with two, and the two positioning protrusions 23 are arranged in a radial symmetry mode.

[0037] When the positioning flange 12 is buckled on the abutting inner ring 22, the positioning flange 12 has an installation gap 24 with the inner side wall of the water pipe nipple 2. When the water pipe is connected in the water pipe nipple 2 through the threaded connection, in order to ensure that the water in the water pipe does not enter the installation gap 24, the water pipe nipple 2 is provided with a sealing gasket 3. That is, it is ensured that the water in the water pipe can only enter the main valve body 1 through the connecting ring 11. Further, the outer ring end face of the sealing gasket 3 is provided with an embedded ring 31 embedded in the installation gap 24, so as to further improve the sealing effect.

[0038] The implementation principle of the water pipe nipple and the stamping type connection structure of the valve body of the embodiment of the application is as follows: when the water pipe nipple 2 and the main valve body 1 are installed, the water pipe nipple 2 is first sleeved on the connecting ring 11, the abutting inner ring 22 abuts against the abutting step 13, and the positioning protrusion 23 is embedded in the positioning groove 14. Then the positioning flange 12 is stamping deformed and buckled against the abutting step 13, and finally the sealing gasket 3 is laid on the positioning flange 12. When the water pipe is threaded connected on the water pipe nipple 2, the end of the water pipe abuts against the sealing gasket 3, at this time the water in the water pipe can enter the main valve body 1 through the connecting ring 11.

[0039] The above are the preferred embodiments of the application, and do not limit the protection scope of the application, so: any equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
