[0023] Reference Figures 1 to 5 A loosening-preventing ferrule according to a preferred embodiment of the present application will be described in detail below, wherein the loosening-preventing ferrule comprises an adjusting and locking member 10 and a surrounding member 20.

[0024] Specifically, the adjusting and locking member 10 comprises an adjusting body 11 and a locking piece 12. The adjusting body 11 forms an adjusting channel 1101. The locking piece 12 is rotatably arranged in the adjusting channel 1101 of the adjusting body 11 in a manner that the extending direction of the locking piece 12 is consistent with the adjusting channel 1101.

[0025] The surrounding member 20 comprises a fixed surrounding part 21, a surrounding adjusting part 22 and at least one connecting part 23. One end of the fixed surrounding part 21 and one end of the surrounding adjusting part 22 are connected by the connecting part 23. The other end of the fixed surrounding part 21 is fixed to the adjusting body 11. The other end of the surrounding adjusting part 22 passes through the adjusting channel 1101 in a manner that it can be driven by the locking part 12 and pass through the adjusting channel 1101, so as to form a fastening channel 201 surrounded by the fixed surrounding part 21, the surrounding adjusting part 22 and the connecting part 23. The extending direction of the connecting part 23 is parallel to the axial direction of the fastening channel 201, and the fixed surrounding part 21 and the surrounding adjusting part 22 are respectively connected to the two ends of the connecting part 23. That is, in the axial direction of the fastening channel 201, the ends of the fixed surrounding part 21 and the surrounding adjusting part 22 connected to the connecting part 23 are staggered with each other. The surrounding adjusting part 22 has a compressed part 221, and the surrounding adjusting part 22 extends circumferentially along the fastening channel 201 to form the compressed part 221 when passing through the adjusting channel 1101. The compressed part 221 is located on the side of the connecting part 23 facing the fastening channel 201.

[0026] It can be understood that the locking part 12 continuously drives the surrounding adjusting part 22 to pass through the adjusting channel 1101, so that the surrounding adjusting part 22 pulls the fixed surrounding part 21 through the connecting part 23, thereby adjusting the inner diameter of the fastening channel 201, so that different sizes of fastened members can be fastened by the surrounding member 20 by being placed in the fastening channel 201 with different inner diameters. That is, after the fastened member is placed in the fastening channel 201, the size of the fastening channel 201 is reduced, so that the fastened member is fastened by the surrounding member 20.

[0027] When the locking part 12 continuously drives the surrounding adjusting part 22 to pass through the adjusting channel 1101, and the surrounding adjusting part 22 drives the fixed surrounding part 21 through the connecting part 23 to reduce the inner diameter of the fastening channel 201, because the compressed part 221 is located on the side of the connecting part 23 facing the fastening channel 201, the compressed part 221 is pressed against the surface of the fastened member in the fastening channel 201 by the connecting part 23, thereby fixing the compressed part 221 of the surrounding adjusting part 22.

[0028] It is worth mentioning that when the locking member 12 drives the surrounding adjusting member 22 to continuously pass through the adjusting channel 1101, the surrounding adjusting member 22 will be fixed by the locking member 12 at the position where the surrounding adjusting member 22 is in contact with the locking member 12, and the compressed part 221 of the surrounding adjusting member 22 is fixed by the connecting member 23, so that when the to-be-fastened member in the fastening channel 201 vibrates, the probability of relative movement between the surrounding adjusting member 22 and the locking member 12 due to vibration is reduced, thereby stably fastening the to-be-fastened member in the fastening channel 201 by the surrounding member 20.

[0029] That is, when the to-be-fastened member in the fastening channel 201 vibrates and transmits the vibration to the surrounding adjusting member 22 and the locking member 12, the surrounding adjusting member 22 and the locking member 12 will tend to move relatively, but since the compressed part 221 of the surrounding adjusting member 22 is fixed by the connecting member 23, the relative movement between the surrounding adjusting member 22 and the locking member 12 is prevented, thereby stably fastening the to-be-fastened member in the fastening channel 201 by the surrounding member 20.

[0030] It can be understood that since the fixed surrounding member 21 and the surrounding adjusting member 22 are connected to the end portions of the connecting member 23 which are mutually staggered in the axial direction of the fastening channel 201, the side projection of the anti-loosening ferrule in the axial direction of the fastening channel 201 is triangular, so as to improve the overall stability of the anti-loosening ferrule when fastening the to-be-fastened member in the fastening channel 201.

[0031] Preferably, the extension direction of the adjusting channel 1101 is tangent to the circumferential direction of the fastening channel 201, so that the surrounding adjusting member 22 can smoothly extend along the circumferential direction of the fastening channel 201 to form the compressed part 221 after passing through the adjusting channel 1101.

[0032] Preferably, the locking member 12 has a locking adjusting part 121. The locking adjusting part 121 is implemented as a thread formed spirally along the extension direction of the locking member 12. The surrounding adjusting member 22 is formed with a plurality of adjusting protrusions 222 which engage with the locking adjusting part 121 along the extension direction.

[0033] It can be understood that the plurality of adjustment protrusions 222 of the surrounding adjustment member 22 penetrate the adjustment channel 1101, and the plurality of adjustment protrusions 222 of the surrounding adjustment member 22 are engaged with the locking adjustment portion 121, so that when the locking member 12 is rotated, the locking adjustment portion 121 is constantly engaged with the plurality of adjustment protrusions 222 of the surrounding adjustment member 22, the surrounding adjustment member 22 is constantly penetrated through the adjustment channel 1101 by the locking adjustment portion 121 of the locking member 12, and the fixed surrounding member 21 is driven by the surrounding adjustment member 22 through the connecting member 23 to reduce and expand the inner diameter of the fastening channel 201.

[0034] In the embodiment, a fixing groove 1201 is formed in the circumferential direction of one end of the locking member 12. The inner wall portion of the adjustment channel 1101 extends to the fixing groove 1201 to form a positioning portion 111, and the positioning portion 111 is matched with the fixing groove 1201, so that when the locking member 12 is rotated, the positioning portion 111 is clamped in the fixing groove 1201 to prevent the locking member 12 from being separated from the adjustment channel 1101.

[0035] In another variant embodiment, a positioning portion 111 is formed in the radial direction of the circumferential direction of one end of the locking member 12, and a fixing groove 1201 matched with the positioning portion 111 is formed in the inner wall of the adjustment channel 1101, so that when the locking member 12 is rotated, the positioning portion 111 is clamped in the fixing groove 1201 to prevent the locking member 12 from being separated from the adjustment channel 1101.

[0036] In order to enable those skilled in the art to understand the present application, in at least one embodiment of the present application, only the fixing groove 1201 is formed in the circumferential direction of one end of the locking member 12, and the inner wall portion of the adjustment channel 1101 extends to the fixing groove 1201 to form the positioning portion 111.

[0037] Preferably, the adjustment body 11 forms a fixed channel 1102 matched with the end of the fixed surrounding member 21, and the end of the fixed surrounding member 21 is connected with the adjustment body 11 by being inserted into the fixed channel 1102 and welded to the inner wall of the fixed channel 1102.

[0038] As a preference, the fixed surrounding member 21 has an anti-disengagement portion 211. After the fixed surrounding member 21 is inserted and penetrated through the fixed channel 1102, the fixed surrounding member 21 is bent in a direction deviating from the extension direction of the fixed channel 1102 to form the anti-disengagement portion 211, so as to prevent the fixed surrounding member 21 from being separated from the fixed channel 1102 due to the disengagement of the fixed surrounding member 21 from the inner wall of the fixed channel 1102, and to improve the stability of the connection of the fixed surrounding member 21 with the adjustment body 11.

[0039] Specifically, the connecting member 23 is partially protruded away from the fastening passage 201 to form a penetrating passage 2301. The penetrating passage 2301 is in communication with the fastening passage 201, and the penetrating passage 2301 is used to penetrate the compressed portion 221.

[0040] It can be understood that, since the compressed portion 221 is placed in the penetrating passage 2301 formed by the connecting member 23, the compressed portion 221 is prevented from entering the fastening passage 201 to hinder the fastened member from being placed in the fastening passage 201, thereby improving the convenience of use of the anti-loose collar.

[0041] For example, after the fastened member is placed in the fastening passage 201, the connecting member 23 is deformed in the process of the surrounding adjusting member 22 driving the fixed surrounding member 21 to reduce and enlarge the inner diameter of the fastening passage 201, so that the inner wall of the penetrating passage 2301 is pressed against the compressed portion 221, thereby pressing the compressed portion 221 against the surface of the fastened member in the fastening passage 201 to prevent the anti-loose collar from loosening.

[0042] Preferably, the extension direction of the penetrating passage 2301 is tangent to the circumference of the fastening passage 201, so as to facilitate the compressed portion 221 to penetrate the penetrating passage 2301.

[0043] Preferably, the surrounding adjusting member 22 further has a stabilizing portion 223, and the compressed portion 221 of the surrounding adjusting member 22 is bent to form the stabilizing portion 223 after penetrating the penetrating passage 2301 to deviate from the extension direction of the penetrating passage 2301, so as to prevent the compressed portion 221 from being separated from the penetrating passage 2301.

[0044] Those skilled in the art should understand that the embodiments of the present application described above and shown in the drawings are only examples and do not limit the present application. The advantages of the present application have been fully and effectively achieved. The functional and structural principles of the present application have been shown and described in the embodiments, and any modification or change can be made to the embodiments of the present application without departing from the principles.
