Description

Technical Field

[0001] The utility model relates to the technical field of household tools, in particular to a press-lock thread lock. Background Art

[0002] In household cleaning tools, in order to facilitate the adjustment of length or the replacement of components, a threaded connection structure is usually used to connect the various components together. However, this threaded connection is prone to looseness during use and requires frequent tightening operations, which brings great inconvenience to the user. Content of the Utility Model

[0003] To solve the above problems, the utility model provides a press-lock thread lock, and the specific technical solution is as follows:

[0004] A press-lock thread lock includes a first connecting portion and a second connecting portion. The first connecting portion is provided with an internal thread, and the second connecting portion is provided with an external thread. The first connecting portion and the second connecting portion are connected through the cooperation of the internal thread and the external thread. A loosening prevention device is provided between the first connecting portion and the second connecting portion; the loosening prevention device includes a button, a spring piece, and a limiting ring. The button and the spring piece are arranged on the second connecting portion and the button is connected to the spring piece. The limiting ring is arranged on the first connecting portion. In the normal state, the spring piece is locked with the limiting ring to prevent the first connecting portion and the second connecting portion from rotating relative to each other. When the button is pressed, the spring piece disengages from the limiting ring, and the first connecting portion and the second connecting portion can rotate relative to each other.

[0005] Further, the button, the spring piece, and the second connecting portion are integrally formed.

[0006] Further, the second connecting portion includes an annular wall. An external thread is provided on a part of the annular wall, and a U-shaped separation slit is provided on another part of the annular wall. The part of the annular wall in the middle of the U-shaped separation slit constitutes the spring piece.

[0007] Further, the button protrudes from the spring piece.

[0008] Further, a protruding buckle is provided at the end of the spring piece.

[0009] Further, the limiting ring is integrally formed at the end of the first connecting portion. The diameter of the limiting ring is larger than that of the first connecting portion. A plurality of card slots are evenly distributed on the inner circumference of the limiting ring. After the second connecting portion is connected to the first connecting portion, the buckle of the spring piece can be engaged with any one of the card slots; when relative rotation is required, only the button needs to be pressed, and the buckle of the spring piece will disengage from the limiting ring.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The two connecting parts can be locked by a spring piece to prevent loosening of the two connecting parts. When relative rotation is required, simply press the button, and the buckle of the spring piece will disengage. In this way, the two connecting parts can rotate relative to each other freely. This design not only ensures safety but also simplifies the operation process. Brief Description of the Drawings

[0015] The technical solutions of the present invention will be described clearly and completely below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present invention.

[0016] The components of the embodiments of the present invention usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0017] All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0019] The present utility model will be further described below with reference to the accompanying drawings.

[0020] As Figures 1 to 2 shown, a press-lock thread lock includes:

[0021] The first connecting part 100 is provided with an internal chamber, and an internal thread 101 is arranged in the internal chamber;

[0022] The second connecting part 200 has a cylindrical outer shape, and an external thread 201 is arranged on its outer part. The second connecting part 200 can be screwed into the internal chamber of the first connecting part 100 and is connected to the internal thread 101 of the internal chamber by means of its external thread 201.

[0023] The innovation of the present utility model lies in that a loosening prevention device is provided to prevent the first connecting part 100 and the second connecting part 200 from loosening after connection.

[0024] The loosening prevention device includes a button 301, a spring piece 302, and a limit ring 303.

[0025] The button 301 and the spring piece 302 can be independent parts or an integral part. In this embodiment, the button 301 and the spring piece 302 are arranged on the second connecting part 200, and the button 301 and the spring piece 302 are integrally formed parts, and the button 301, the spring piece 302 and the second connecting part 200 are also integrally formed parts. More specifically, the second connecting part 200 is composed of an annular wall. On a part of the annular wall, the external thread 201 is provided. On another part of the annular wall, a U-shaped separation seam 202 is machined. The annular wall in the middle of the U-shaped separation seam 202 constitutes the spring piece 302. This design of the spring piece 302 enables it to deform under an external force and can restore to its original shape depending on its own material properties. This material can be plastic or the like. Among them, the button 301 is a protruding part arranged outside the spring piece 302. Among them, a protruding buckle 303 is provided at the end of the spring piece 302.

[0026] The limit ring 303 and the first connecting part 100 can be independent parts or an integral part. In this embodiment, the limit ring 303 is integrally formed at the end of the first connecting part 100 and has a diameter larger than that of the first connecting part 100. A plurality of card slots 304 are evenly distributed on the inner circumference of the limit ring 303. When the second connecting part 200 rotates into the internal chamber, the buckle 303 of the spring piece 302 can be locked into any one of the card slots 304 to prevent the first connecting part 100 and the second connecting part 200 from loosening after connection. Finally, we need to say that when relative rotation is required, only need to press the button 301, and the buckle 303 of the spring piece 302 will disengage from the limit ring 303. In this way, the first connecting part 100 and the second connecting part 200 can perform relative rotation.

[0027] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the claims of the present invention.
