[0027] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-6 As shown, the utility model provides a novel integrated adjustable locking device, including an elastic locking mechanism and a fixed tube 15, wherein the elastic locking mechanism is fixedly connected to the fixed tube 15; after the elastic locking mechanism is fixedly connected to the fixed tube 15, one end of the elastic locking mechanism is connected to a first circular tube 13 for connecting to an external device, and a curtain rod, a shower curtain rod, a mop rod, a fishing rod and other devices are connected through the first circular tube 13. In some other embodiments, the rod-shaped structure on the curtain rod, shower curtain rod, mop rod, fishing rod and other devices can also be used as the first circular tube 13 to connect the elastic locking mechanism to achieve the purpose of local extension and retraction.

[0029] In this embodiment, the elastic locking mechanism includes a locking nut 1, a connecting tube 3, a spring 4, a sleeve 5, a fixing piece 6, an adjusting screw 8, and a locking ring 7. The spring 4 is sleeved on the outer periphery of the sleeve 5, and one end of the sleeve 5 is inserted into the fixing piece 6 and abuts against the fixing piece 6. The other end of the sleeve 5 is inserted into the interior of the connecting tube 3 and is slidably connected between the connecting tubes 3. The spring 4 abuts between the connecting tube 3 and the fixing piece 6, and the adjusting screw 8 passes through the fixing piece 6, the sleeve 5, and the connecting tube 3 in sequence and is fixedly connected to the locking nut 1; after the above structure is installed, the adjusting screw 8 and the locking nut 1 cooperate to set the connecting tube 3, the spring 4, the sleeve 5, and the fixing piece 6 on the same axis. The working process of the elastic locking mechanism is that when the connecting tube 3 compresses and relaxes the spring, the connecting tube 3 moves back and forth along the sleeve 5 to achieve the purpose of elastic adjustment and extension.

[0030] In this embodiment, the fixing member 6 includes a main body 9 and a tapered thread 10. The locking ring 7 is provided with an internal thread, and the internal thread is an internal tapered thread. The tapered thread 10 is fixedly connected to the outer periphery of the main body 9, and the locking ring 7 is threadedly connected to the tapered thread 10. In some other embodiments, the tapered thread 10 can also be integrally formed on the main body 9.

[0031] In this embodiment, the fixing tube 15 is sleeved on the outer circumference of the elastic locking mechanism. In order to fix the elastic locking mechanism and the fixing tube 15, the elastic locking mechanism is screwed as a whole, the locking ring 7 is screwed along the tapered thread 10, and then the locking ring 7 is stretched open so that the locking ring 7 is clamped on the inner wall of the fixing tube 15, thereby achieving the effect of fixing the elastic locking mechanism and the fixing tube 15.

[0032] In order to improve the convenience of use, the locking ring 7 is better stretched. The locking ring 7 is an open columnar structure. When the locking ring 7 is gradually screwed onto the tapered thread 10, the locking ring 7 is gradually stretched to increase the outer diameter of the locking ring 7 and further improve the fixing effect.

[0033] In order to improve stability, a number of protrusions are provided on the outer circumference of the locking ring 7, which can increase the friction between the locking ring 7 and the fixing tube 15; and in order to improve the friction effect of the protrusions, the protrusions are strip-shaped structures, and the protrusions are arranged along the length direction of the locking ring 7. In some other embodiments, the protrusions can also be point-shaped protrusions, axial ribs, etc., to achieve anti-slip effects in different situations.

[0034] In this embodiment, in order to facilitate the locking ring 7 to be inserted into the fixing tube more conveniently, the end of the locking ring 7 away from the fixing member 6 is conical.

[0035] In this embodiment, a gasket 2 is also included, which is located between the connecting tube 3 and the locking nut 1. The gasket 2 includes a limiting plate 11 and a guide column 12. The guide column 12 is integrally formed with or fixedly connected to the limiting plate 11. The guide column 12 extends into the interior of the connecting tube 3. The large-diameter limiting plate 11 prevents the locking nut 1 from sinking into the hole of the connecting tube 3, and the guide column 12 facilitates the connection between the gasket 2 and the connecting tube 3.

[0036] In this embodiment, in order to increase the scope of use of the present device, it also includes a first circular tube 13 and a second circular tube 14. The first circular tube 13 is sleeved on the connecting tube 3 and fixedly connected to the connecting tube 3. The first circular tube 13 is connected to devices such as curtain rods, shower curtain rods, mop rods, and fishing rods. The second circular tube 14 is sleeved on the first circular tube 13 and fixedly connected to the first circular tube 13. The first circular tube 13 and the second circular tube 14 are kept flush on one side close to the connecting tube 3, and the second circular tube 14 is slidably connected to the fixed tube 15.

[0037] In this embodiment, in order to prevent circumferential sliding between the connecting tube 3 and the sleeve 5 , the sleeve 5 is a square tube, and the inner hole shape of the connecting tube 3 is consistent with the outer circumferential shape of the sleeve 5 to match the sleeve 5 .

[0038] When installing the present invention, the locking nut 1, connecting tube 3, spring 4, sleeve 5, fixing piece 6, adjusting screw 8 and locking ring 7 of the elastic locking mechanism are first connected in the above manner, and then the first circular tube 13 is connected to the connecting tube 3. The second circular tube sleeve 14 is connected to the first circular tube 13 and fixedly connected to the first circular tube 13, and the first circular tube 13 and the second circular tube 14 are kept flush with each other on the side close to the connecting tube 3. Then, the above-mentioned connecting structure is extended into the fixed tube 15 as a whole, and the first circular tube 13 is screwed to drive the elastic locking mechanism to rotate, and the locking ring 7 is stretched open, so that the elastic locking mechanism is engaged with the inner wall of the fixed tube 15, completing the overall assembly of the device.

[0039] During specific use, the first circular tube 13 is used to connect curtain rods, shower curtain rods, mop rods, fishing rods and other devices. The rod-shaped structure on curtain rods, shower curtain rods, mop rods, fishing rods and other devices can also be used as the first circular tube to connect the elastic locking mechanism. When the first circular tube 13 is compressed, the first circular tube 13 presses the elastic locking mechanism, and the connecting tube 3 in the elastic locking mechanism presses the spring 4. The spring 4 contracts, and the connecting tube 3 moves along the sleeve 5 to approach the fixing member 6. When the first circular tube 13 is released, the spring 4 relaxes, and the connecting tube 3 moves in the opposite direction along the sleeve 5, away from the fixing member 6, so as to achieve the purpose of local extension and retraction.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
