[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0031] Example 1

[0032] Reference Figures 1-10 This is the first embodiment of the present invention, which provides a quick-install anti-loosening connector. The quick-install anti-loosening connector includes a main body component 100 and a fixing component 200. The main body component 100 is used to install various components and to connect two pipes. The fixing component 200 is used to pre-connect the main body component 100 to the two pipes and to lock it under the action of water flow in the pipes. The greater the impact force of the water flow in the pipes, the greater the locking force between the fixing component 200 and the pipes, thereby preventing the main body component 100 from loosening from the pipes.

[0033] Specifically, the main component 100 includes a sleeve 101 and a sliding member 102. The sliding member 102 is slidably mounted on the sleeve 101. During the process of inserting the sleeve 101 into the pipe, the end of the pipe presses against the sliding member 102, forcing the sliding member 102 to slide on the sleeve 101.

[0034] Preferably, the fixing component 200 includes a turbine component 201 and a locking component 202. The turbine component 201 is rotatably mounted on the inner wall of the sleeve component 101, and the locking component 202 is also disposed inside the sleeve component 101. The locking component 202 can abut against the inner wall of the pipe. When the sleeve component 101 is inserted into the pipe, the end of the pipe presses against the sliding component 102, forcing the sliding component 102 to slide on the sleeve component 101. The sliding component 102 gradually drives the locking component 202 to abut against the inner wall of the pipe, so that the pipe joint pre-connects two pipes. When water flows through the pipe, the turbine component 201 rotates under the action of the water flow. The turbine component 201 drives the locking component 202 to further lock with the pipe, thereby preventing the pipe joint from loosening between the pipe and the pipe. Moreover, the greater the impact force of the water flow in the pipe, the less likely the pipe joint is to loosen between the pipe and the pipe.

[0035] In use, the sliding member 102 is pre-assembled onto the sleeve member 101, and then the sleeve member 101 is inserted into the end of the pipe. During the connection between the sleeve member 101 and the pipe, the end of the pipe abuts against the sliding member 102, and the pipe gradually pushes the sliding member 102 to slide. During the sliding of the sliding member 102, the sliding member 102 drives the locking member 202 to pre-tighten against the inner wall of the pipe, so that the pipe joint pre-connects the two pipes. When the water flows through the pipe, the turbine member 201 rotates under the action of the water flow. The turbine member 201 drives the locking member 202 to further lock with the pipe, thereby preventing the pipe joint from becoming loose.

[0036] Example 2

[0037] Reference Figures 1-10 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the sleeve 101 is hollow inside and open at both ends. An annular first sliding groove 101a is formed on the inner wall of the sleeve 101, and an annular first insertion groove 101b is formed on both ends of the sleeve 101. An annular second insertion groove 101c is formed on the first insertion groove 101b. The central axis of the second insertion groove 101c coincides with the central axis of the first insertion groove 101b. Two sliding members 102 are provided. The two sliding members 102 are respectively slidably installed in the first insertion groove 101b on both ends of the sleeve 101. In use, the sliding members 102 are pre-assembled into the first insertion groove 101b of the sleeve 101, and then the sleeve 101 is inserted into the end of the pipe. The pipe pushes the sliding members 102 to slide in the first insertion groove 101b.

[0039] Preferably, the slider 102 includes a first slider 102a and a second slider 102b, which are integrally formed. Both sliders are made of rubber and are annular in shape. The central axis of the first slider 102a coincides with the central axis of the second slider 102b. The first slider 102a is slidably connected to the first insertion groove 101b, and the second slider 102b is slidably connected to the second insertion groove 101c. The wall thickness of the first slider 102a is greater than that of the second slider 102b. In use, the slider 102 is pushed by the pipe, and the first slider 102a slides in the first insertion groove 101b, while the second slider 102b slides in the second insertion groove 101c.

[0040] Preferably, the turbine component 201 includes an annular frame 201a and blades 201b. The annular frame 201a has a circular cross-sectional shape, and at least one blade 201b is provided. In this embodiment, there are twelve blades 201b. The twelve blades 201b are evenly arranged around the center of the annular frame 201a on the inner wall of the annular frame 201a. The annular frame 201a is slidably installed in the first groove 101a of the sleeve component 101. When water flows through the pipe, the water flow acts on the blades 201b, causing the annular frame 201a to have a rotational tendency.

[0041] Preferably, a second groove 101d is also provided on the inner wall of the sleeve 101. The length direction of the second groove 101d is parallel to the central axis direction of the sleeve 101. The second groove 101d passes through the first groove 101a. The first groove 101a divides the second groove 101d into a first groove 101d-1 and a second groove 101d-2. The annular frame 201a has a wedge-shaped first protrusion 201a-1 and a second protrusion 201a-2 on both ends. The first protrusion 201a-1 is located in the first groove 101d-1, and the second protrusion 201a-2 is located in the second groove 101d-2. The annular frame 201a also has a first clearance groove 201a-3 and a second clearance groove 201a-4 on both ends. The inclined surface of the first protrusion 201a-1 coincides with the inclined surface of the first clearance groove 201a-3, and the inclined surface of the second protrusion 201a-2 coincides with the inclined surface of the second clearance groove 201a-4.

[0042] Furthermore, the locking member 202 includes a support column 202a, a friction block 202b, and a connecting rod 202c. The support column 202a is disposed on the inner wall of the sleeve member 101, the connecting rod 202c is hinged to the support column 202a, and the friction block 202b is hinged to the connecting rod 202c. The friction block 202b is adapted to abut against the inner wall of the pipe. An annular inclined groove 102b-1 is formed on the inner wall of the second slider 102b, and an abutting post 202c-1 is provided on the connecting rod 202c. The abutting post 202c-1 is adapted to abut against the annular inclined groove 102a. When the second slider 102b moves toward the center of the sleeve 101, it drives the abutting post 202c-1 to move toward the central axis of the sleeve 101. The abutting post 202c-1 drives the connecting rod 202c to rotate, and the connecting rod 202c drives the friction block 202b to move toward the inner wall of the pipe. When the second slider 102b slides to the deepest part of the first insertion groove 101b, the friction block 202b abuts against the inner wall of the pipe, so that the pipe joint and the pipe are pre-connected.

[0043] Furthermore, the locking member 202 includes a first transmission block 202d and a second transmission block 202e. The first transmission block 202d is slidably installed in the first groove 101d-1, and the second transmission block 202e is slidably installed in the second groove 101d-2. A first spring 202f is provided on the first transmission block 202d and is connected to the first groove 101d-1. A second spring 202g is provided on the second transmission block 202e and is connected to the second groove 101d-2, which facilitates the reset of the first transmission block 202d and the second transmission block 202e.

[0044] Furthermore, the first transmission block 202d is provided with a first inclined portion 202d-1, which abuts against the first protrusion 201a-1 on the ring frame 201a, and the first inclined portion 202d-1 is adapted to extend into the first clearance groove 201a-3, thereby increasing the sliding stroke of the first transmission block 202d. The second transmission block 202e is provided with a second inclined portion 202e-1, which abuts against the second protrusion 201a-2 on the ring frame 201a. The second inclined portion 202e-1 is adapted to extend into the second clearance groove 201a-4. Both the first transmission block 202d and the second transmission block 202e are provided with slots 202h, and the abutment post 202c-1 is provided with a locking block 202c-2, which is adapted to abut against the slot 202h. When the second slider 102b slides to the deepest point of the first insertion groove 101b, the friction block 202b abuts against the inner wall of the pipe. At this time, the locking block 202c-2 of the abutment post 202c-1 is just located in the slot 202h. In step h, prior to this, the locking block 202c-2 of the contact post 202c-1 is not in contact with the slot 202h; when water flows through the pipe, the water flow acts on the blade 201b, causing the annular frame 201a to tend to rotate. The first protrusion 201a-1 on the annular frame 201a acts on the first inclined portion 202d-1 on the first transmission block 202d, and the second protrusion 201a-2 on the annular frame 201a acts on the second inclined portion 202e-1 on the second transmission block 202e, forcing the first transmission block 202a to rotate. 2d slides in the first groove 101d-1, and the second transmission block 202e slides in the second groove 101d-2. The slot 202h on the first transmission block 202d pushes the locking block 202c-2 on the abutment post 202c-1, forcing the abutment post 202c-1 to move towards the central axis of the sleeve 101. The abutment post 202c-1 drives the connecting rod 202c to rotate, and the connecting rod 202c drives the friction block 202b to move further towards the inner wall of the pipe until the friction block 202b locks with the inner wall of the pipe.

[0045] Furthermore, an annular mounting groove 101e is provided on the inner wall of the first sliding groove 101a. There is at least one mounting groove 101e. In this embodiment, two mounting grooves 101e are provided on the first sliding groove 101a at both ends of the sleeve 101. A sealing ring 101f is provided in the mounting groove 101e. The sealing ring 101f is interference-fitted with the pipe to prevent water leakage.

[0046] In use, the sliding member 102 is pre-assembled into the first insertion groove 101b of the sleeve member 101, and then the sleeve member 101 is inserted into the end of the pipe. The pipe pushes the sliding member 102 to slide in the first insertion groove 101b. The second slider 102b moves toward the center of the sleeve member 101. The second slider 102b drives the abutment post 202c-1 to move toward the central axis of the sleeve member 101. The abutment post 202c-1 drives the connecting rod 202c to rotate. The connecting rod 202c drives the friction block 202b to move toward the inner wall of the pipe. The friction block 202b abuts against the inner wall of the pipe, so that the pipe joint and the pipe are pre-connected.

[0047] When water flows through the pipe, the water flow acts on the blade 201b, causing the annular frame 201a to tend to rotate. The first protrusion 201a-1 on the annular frame 201a acts on the first inclined portion 202d-1 on the first transmission block 202d, and the second protrusion 201a-2 on the annular frame 201a acts on the second inclined portion 202e-1 on the second transmission block 202e, forcing the first transmission block 202d to slide in the first groove 101d-1 and the second transmission block 202e to slide in the second groove 101d-2. The slot 202h pushes the locking block 202c-2, and the contact post 202c-1 drives the connecting rod 202c to rotate. The connecting rod 202c drives the friction block 202b to move further toward the inner wall of the pipe until the friction block 202b locks with the inner wall of the pipe.

[0048] Example 3

[0049] Reference Figures 1-10 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0050] Specifically, the outer wall of the sleeve 101 is provided with a clearance groove, which is connected to the first sliding groove 101a. After the pipe joint is installed on the pipe, an unlocking rod is fixed on the outer wall of the second slider 102b. The top of the unlocking rod passes through the clearance groove. When it is necessary to disassemble the joint, the flow of water in the pipe is stopped, and the unlocking rod is manually moved. The unlocking rod forces the sliding block to move away from the center of the sleeve 101, so that when disassembling the pipe joint, the second slider 102b will not obstruct the reverse movement of the abutment post 202c-1 of the connecting rod 202c, thus facilitating disassembly.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
