Description

Technical Field

[0001] The utility model relates to the technical field of nut structures, in particular to a copper nut capable of slowing down rusting. Background Art

[0002] At present, there are mainly the following methods to slow down the rusting of copper nuts:

[0003] Surface treatment: Through electroplating, spraying, chemical conversion and other methods (including the use of rust inhibitors), a protective film is formed on the surface of the copper nut to reduce the possibility of rust.

[0004] Choose the right material: Use copper alloys or stainless steel with better corrosion resistance to make copper nuts. These materials themselves have strong corrosion resistance and can reduce the risk of rust.

[0005] Set up the protective cover: Install the protective cover on the periphery.

[0006] However, except for setting the protective cover, the above methods cannot effectively slow down the rusting of the copper nut. However, the current method of setting the protective cover to slow down the rusting has the following defects:

[0007] 1. The installation conditions affect the setting of the protective cover, and the protective cover currently used on the copper nut is not compact enough, and the space cannot provide support;

[0008] 2. The installation is not stable enough, usually they are snapped together and are easy to fall off and lose;

[0009] 3. The moisture-proof effect needs to be improved;

[0010] Therefore, we propose a copper nut that can slow down rusting. By designing the copper nut structure and integrating the protective structure, the rusting effect is slowed down. Utility Model Content

[0011] The purpose of the utility model is to solve the shortcomings existing in the prior art. The setting of the protective cover is affected by the installation conditions, and the structure of the protective cover currently used on the copper nut is not compact enough and the space cannot provide support; the installation is not stable enough and is generally snapped together, which is easy to fall off and lost; the moisture-proof effect needs to be improved.

[0012] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0013] A copper nut capable of slowing down rusting comprises a copper nut and a protective sleeve, wherein the protective sleeve is fitted on the upper end and the periphery of the copper nut, and a circular groove is provided on the top of the copper nut around a threaded mounting hole;

[0014] The upper end of the protective sleeve corresponding to the copper nut is rotatably connected with a connecting disk, and the bottom of the connecting disk is provided with an annular threaded sleeve adapted to the circular groove.

[0015] Furthermore, an inner thread is provided on the outer ring of the annular groove, so that the annular threaded sleeve can be threadedly connected to the annular groove.

[0016] Furthermore, the connection plate is provided with a screw rod passage opening with the same aperture as the aperture of the copper nut threaded mounting hole, and a sealing ring is provided on the annular wall of the screw rod passage opening.

[0017] Furthermore, a sealing gasket is provided along the edge of the bottom of the protective cover.

[0018] Furthermore, the protective sleeve is provided with a rotation groove on the outer annular wall corresponding to the connecting disk, and the outer periphery of the connecting disk is provided with a rotation convex ring adapted to the rotation groove.

[0019] Furthermore, a protrusion is provided on the top of the connecting disk to assist in rotating the connecting disk.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] In view of the first and second defects, the protective sleeve is designed to fit tightly with the upper end and periphery of the copper nut, and the annular threaded sleeve at the bottom of the connecting plate is threaded with the annular groove on the copper nut to achieve a stable connection between the protective sleeve and the copper nut. This structure is not only compact, but also stable to install and not easy to fall off and lose.

[0022] By designing a rotating groove on the outer annular wall of the protective sleeve corresponding to the connecting disk and a rotating convex ring on the outer periphery of the connecting disk, the connecting disk can be rotated on the protective sleeve, so that the sleeve can be installed on the copper nut by completing the rotation of the connecting disk during the docking process with the copper nut. A protrusion is provided on the top of the connecting disk to assist in rotating the connecting disk, making the operation more convenient.

[0023] In response to the third defect, the connecting plate is provided with a screw passage opening of the same diameter as the threaded mounting hole of the copper nut, and a sealing ring is provided on the annular wall of the screw passage opening to effectively prevent moisture from penetrating through the mounting hole of the protruding part of the screw, thereby improving the moisture-proof effect. At the same time, a sealing gasket is provided along the edge of the bottom of the protective cover to further enhance the overall sealing and moisture-proof performance.

The term "and / or" used in this article includes any and all combinations of one or more related listed items. Example

[0035] like Figure 1-4As shown, the utility model provides a technical solution: a copper nut capable of slowing down rusting, comprising a copper nut 1 and a protective sleeve 2, wherein the protective sleeve 2 fits on the upper end and the periphery of the copper nut 1, and a circular groove 11 is provided on the top of the copper nut 1 around the threaded mounting hole;

[0036] The protective sleeve 2 is rotatably connected to the upper end of the copper nut 1 with a connecting plate 21 , and an annular threaded sleeve 22 adapted to the annular groove 11 is provided at the bottom of the connecting plate 21 . Example

[0037] like Figure 1-4 As shown, an inner thread is provided on the outer ring of the annular groove 11 so that the annular threaded sleeve 22 can be threadedly connected with the annular groove 11 .

[0038] The connecting plate 21 is provided with a screw rod passage 23 of the same diameter as the threaded mounting hole of the copper nut 1, and a sealing ring 24 is provided on the annular wall of the screw rod passage 23. When a bolt or other fastener passes through the screw rod passage 23, the sealing ring 24 contacts the bolt or other fastener, thereby effectively preventing moisture or other corrosive media from penetrating from the mounting hole, thereby ensuring a dry environment inside. A sealing gasket 25 is provided along the edge of the bottom of the protective cover 2, which contacts the mounting surface after installation, thereby further enhancing the overall sealing performance and effectively preventing external moisture or corrosive media from entering.

[0039] A rotation groove 26 is formed on the outer annular wall of the protective sleeve 2 corresponding to the connecting plate 21 , and a rotation convex ring 27 is formed on the periphery of the connecting plate 21 to adapt to the rotation groove 26 .

[0040] A protrusion 28 is provided at the top of the connecting disk 21 to assist in rotating the connecting disk 21 and improve installation efficiency.

[0041] The working process of the utility model is as follows: first, the protective sleeve 2 is placed above the copper nut 1 to ensure that the lower part of the protective sleeve 2 fits the outer periphery of the copper nut 1, then confirm that the annular threaded sleeve 22 at the bottom of the connecting disk 21 corresponds to the position of the annular groove 11 at the top of the copper nut 1, and at the same time, the connecting disk 21 is rotated to make the annular threaded sleeve 22 threadedly connected with the annular groove 11. Since the outer ring of the annular groove 11 is provided with an internal thread, the annular threaded sleeve 22 can be smoothly screwed into the annular groove 11 to achieve tight fixation. When rotating the connecting disk 21, the protrusion 28 at the top of the connecting disk 21 can be used as an auxiliary to make the operation more convenient. Since the protective sleeve 2 is not affected by the rotation of the connecting disk 21, it is connected with the copper nut 1 through the combination of the annular threaded sleeve 22 and the copper nut 1, and moves downward to complete the sealing protection of the copper nut 1; when it is necessary to remove or replace the protective sleeve 2, it is only necessary to rotate the connecting disk 21 in the opposite direction to screw the annular threaded sleeve 22 out of the annular groove 11 and then take out the protective sleeve 2.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
