[0016] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0017] The utility model provides a quick-release locking device used in an assembly structure of a steering machine and a steering wheel.

[0018] Please refer to Figures 1 to 4 As shown, a quick-release locking device of the present invention includes a first fixing seat 1 and a second fixing seat 2. The first fixing seat 1 and the second fixing seat 2 are coaxially plugged into each other. The first fixing seat 1 is provided with an elastic block 11 in the radial direction, and the second fixing seat 2 is provided with a notch 21 that is engaged with the elastic block 11.

[0019] As can be seen from the above description, the beneficial effects of the present invention are: a quick-release locking device, wherein the first fixing seat 1 and the second fixing seat 2 are respectively connected to different main bodies. After the first fixing seat 1 and the second fixing seat 2 are coaxially plugged in, the elastic block 11 provided along the diameter of the first fixing seat 1 is snapped into the notch 21 of the second fixing seat, which can prevent the first fixing seat 1 and the second fixing seat 2 from rotating relative to each other, thereby preventing the two main bodies from rotating circumferentially after mating. The quick-release locking device provided by the present invention can eliminate the circumferential rotational shaking of the first fixing seat 1 and the second fixing seat 2 after mating due to dimensional accuracy, assembly errors, etc., which in turn affects the structural stability of the two main bodies after assembly, thereby improving the assembly accuracy of the product.

[0020] In an optional embodiment, the first fixing seat 1 is provided with a mounting plate 12 , and the elastic block 11 is locked to the mounting plate 12 via a fastener 13 .

[0021] As can be seen from the above description, the mounting plate 12 plays a supporting and fixing role, and is used to install the elastic block 11 at a preset position of the first fixing seat 1.

[0022] In an optional embodiment, the elastic block 11 includes a support block 111, a spring 112 and a positioning block 113, the support block 111 is connected to the mounting plate 12, the support block 111 is located on the axis of the first fixed seat 1, the positioning block 113 is connected to the support block 111 through the spring 112, the spring 112 and the positioning block 113 are arranged along the diameter of the first fixed seat 1, and the positioning block 113 is engaged with the notch 21.

[0023] From the above description, it can be seen that the support block 111 is installed on the axis of the first fixing seat 1 to support one end of the spring 112 , and the positioning block 113 is connected to the other end of the spring 112 and is engaged with the notch 21 for positioning.

[0024] In an optional embodiment, two groups of positioning blocks 113 are symmetrically arranged on opposite sides of the support block 111 , and the second fixing seat 2 is provided with two symmetrical notches 21 .

[0025] It can be seen from the above description that the above design is more conducive to improving the structural stability of the quick-release locking device in the circumferential direction.

[0026] In an optional embodiment, the first fixing seat 1 is provided with a limiting groove 14 engaged with the positioning block 113 .

[0027] As can be seen from the above description, the function of the limiting groove 14 is to prevent the positioning block 113 from shaking and falling off, thereby improving the structural stability.

[0028] Please refer to Figures 1 to 4As shown, embodiment 1 of the present invention is: a quick-release locking device, comprising a first fixing seat 1 and a second fixing seat 2, the first fixing seat 1 and the second fixing seat 2 are coaxially plugged into each other, the first fixing seat 1 is provided with an elastic block 11 in the radial direction, and the second fixing seat 2 is provided with a notch 21 that is engaged with the elastic block 11.

[0029] The first fixing seat 1 is provided with a mounting plate 12, and the elastic block 11 is locked to the mounting plate 12 via a fastener 13. The elastic block 11 includes a support block 111, a spring 112, and a positioning block 113. The support block 111 is connected to the mounting plate 12 and is located on the axis of the first fixing seat 1. The positioning block 113 is connected to the support block 111 via a spring 112. The spring 112 and the positioning block 113 are arranged along the diameter of the first fixing seat 1, and the positioning block 113 is engaged with the notch 21. Two groups of the positioning blocks 113 are symmetrically arranged on opposite sides of the support block 111, and the second fixing seat 2 is provided with two symmetrical notches 21. The first fixing seat 1 is provided with a limiting groove 14 that is engaged with the positioning block 113.

[0030] In summary, in the quick-release locking device of the present invention, the first and second fixing seats are connected to different main bodies, respectively. After the first and second fixing seats are coaxially plugged in, the elastic block provided along the diameter of the first fixing seat snaps into the notch of the second fixing seat, thereby preventing the first and second fixing seats from rotating relative to each other, thereby preventing circumferential rotational offset of the two main bodies after mating. The quick-release locking device provided by the utility model can eliminate the circumferential rotational shaking of the first and second fixing seats after mating due to reasons such as dimensional accuracy and assembly errors, which in turn affects the structural stability of the two main bodies after assembly, thereby improving the assembly accuracy of the product.
