DETAILED DESCRIPTION
[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] Example:
[0034] like Figures 1-10 As shown, this embodiment provides an anti-loosening connector, including a first connector 10, on which a second connector 40 is arranged;
[0035] A mounting screw sleeve 11 is rotatably provided on the first connecting head 10, and the mounting screw sleeve 11 is provided with a threaded inner wall 116. A connecting column 41 is provided on the second connecting head 40, and a threaded outer wall 42 is provided on the connecting column 41. The threaded outer wall 42 is adapted to the threaded inner wall 116. The outer wall of the connecting column 41 is also sleeved with a positioning outer gear ring 30. A positioning assembly 20 is provided on the outer wall of the mounting screw sleeve 11, and the threaded inner wall 116 is threadedly connected to the threaded outer wall 42, so that the positioning assembly 20 is stuck on the positioning outer gear ring 30 to limit the mounting screw sleeve 11.
[0036] In this embodiment, when the first connector 10 and the second connector 40 are connected, the first connector 10 and the second connector 40 are aligned, and the mounting sleeve 11 and the connecting column 41 are aligned. Then, the mounting sleeve 11 is rotated. Through the thread fit between the mounting sleeve 11 and the thread outer wall 42, the mounting sleeve 11 is connected to the connecting column 41. When the mounting sleeve 11 is completely connected to the connecting column 41, the positioning component 20 is snapped onto the positioning external gear ring 30 to limit the mounting sleeve 11;
[0037] By the combined use of the positioning component 20 and the positioning external gear ring 30, an additional limiting function is provided for the mounting sleeve 11, enhancing the stability between the first connector 10 and the second connector 40, preventing the mounting sleeve 11 from loosening due to vibration or external force. At the same time, the positioning component 20 also wraps and shields the joint between the mounting sleeve 11 and the connecting column 41, effectively preventing particulate impurities from entering the interior of the mounting sleeve 11 and affecting the normal thread connection process, greatly improving the overall practicality.
[0038] Specifically, the positioning component 20 includes a positioning sleeve 23, and the positioning sleeve 23 is sleeved on the outer wall of the mounting sleeve 11;
[0039] A positioning internal gear ring 22 is fixedly arranged on the inner wall of the positioning sleeve 23, and the positioning internal gear ring 22 is adapted to the positioning external gear ring 30.
[0040] Specifically, two groups of positioning chutes 111 are formed on the outer wall of the mounting sleeve 11, and the two groups of positioning chutes 111 are symmetrically arranged;
[0041] Two groups of positioning blocks 25 are arranged on the inner wall of the positioning sleeve 23, the two groups of positioning blocks 25 are symmetrically arranged, and the two groups of positioning blocks 25 are respectively slidably arranged in the two groups of positioning chutes 111.
[0042] In this embodiment, when the mounting sleeve 11 is thread-mounted to the specified position, the positioning sleeve 23 slides on the mounting sleeve 11, that is, the positioning blocks 25 slide in the positioning chutes 111, so that the positioning sleeve 23 is displaced towards the positioning external gear ring 30 until the positioning internal gear ring 22 is snapped onto the positioning external gear ring 30 to complete the positioning process.
[0043] Specifically, a rotating groove 113 is formed on the positioning chute 111, and the rotating groove 113 is adapted to the positioning chute 111;
[0044] The positioning sleeve 23 rotates around the axis of the mounting sleeve 11, so that the positioning blocks 25 enter the rotating groove 113 to limit the positioning sleeve 23.
[0045] Specifically, the outer wall of the mounting screw sleeve 11 is provided with a first movable groove 115, and the inner wall of the positioning sleeve 23 is provided with a second movable groove 24, and the positions of the first movable groove 115 and the second movable groove 24 match;
[0046] A movable spring 50 is disposed between the first movable groove 115 and the second movable groove 24 .
[0047] In this embodiment, when the positioning inner gear ring 22 is not inserted into the positioning outer gear ring 30, the positioning sleeve 23 rotates about the axis of the mounting screw sleeve 11, so that the positioning block 25 enters the rotating groove 113 and squeezes the movable spring 50 at the same time. When the positioning inner gear ring 22 needs to be inserted into the positioning outer gear ring 30, it is only necessary to rotate the positioning sleeve 23, and the squeezed movable spring 50 is reset, driving the positioning sleeve 23 to move toward the positioning outer gear ring 30, so that the positioning inner gear ring 22 is inserted into the positioning outer gear ring 30, completing the limiting process.
[0048] Specifically, the first movable groove 115 is provided with a first contact surface 114, and the second movable groove 24 is provided with a second contact surface 241;
[0049] The movable spring 50 is disposed between the first contact surface 114 and the second contact surface 241 .
[0050] In this embodiment, the first contact surface 114 and the second contact surface 241 are set to facilitate the installation of the movable spring 50. When the positioning sleeve 23 is placed in the rotating groove 113, the second contact surface 241 drives the movable spring 50 to be compressed, so that the positioning sleeve 23 can automatically move and snap into the positioning outer gear ring 30.
[0051] Specifically, the outer wall fixing sleeve of the mounting screw sleeve 11 is provided with an outer hexagonal toggle block 112 , and the outer wall of the positioning sleeve 23 is provided with multiple groups of anti-slip grooves 21 .
[0052] In this embodiment, the external hexagonal toggle block 112 can facilitate the installation screw sleeve 11 to rotate, and the anti-slip groove 21 can facilitate the positioning sleeve 23 to rotate.
[0053] 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.
