[0018] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0021] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar attributes, not to indicate or imply relative importance or a specific order.

[0022] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0023] Please see Figure 1 The quick-release structure provided by this utility model includes an upper plate 1, a lower plate 2 and a quick-release component 3. The quick-release component 3 is assembled between the upper plate 1 and the lower plate 2 for fixing the upper plate 1 and the lower plate 2, and for separating the upper plate 1 and the lower plate 2 when separation is required.

[0024] Understandably, the lower plate 2 can be detachably fixed to the bracket. Detachment can be achieved by bolt connection or welding to the bracket. The upper plate 1 can be connected and fixed to the workpiece to be processed by bolts. When the corresponding workpiece needs to be processed, the upper plate 1 can be pre-fixed to the workpiece. The upper plate is quickly fixed to the lower plate 2 by quick-release component 3. After the workpiece is processed, the upper plate 1 can be quickly removed from the lower plate 2, and then the next workpiece to be processed can be fixed and processed.

[0025] Please see Figure 2 In some embodiments, the quick-release component 3 includes an upper latching part 301 and a lower latching part 302. The upper latching part 301 is mounted on the upper plate 1, and the lower latching part 302 is rotatably mounted in the lower plate 2. When the lower latching part 302 is rotated to the latching position, the upper latching part 301 and the lower latching part 302 are latched and fixed. When the lower latching part 302 is rotated to the separation position, the upper latching part 301 and the lower latching part 302 are disengaged from each other.

[0026] It is known that the upper snap-fit ​​part 301 can be an integral structure with the upper plate 1, or it can be connected together by welding or other means. The upper snap-fit ​​part 301 and the lower snap-fit ​​part 302 can be in two states: one is a snap-fit ​​state, in which the lower snap-fit ​​part 302 rotates relative to the lower plate 2. When it rotates to the snap-fit ​​position, the upper snap-fit ​​part 301 and the lower snap-fit ​​part 302 can be snapped and fixed. The other state is a separation state, in which the upper snap-fit ​​part 301 and the lower snap-fit ​​part 302 are separated when the lower snap-fit ​​part 302 rotates to the separation position, thereby realizing the quick disassembly and assembly of the upper snap-fit ​​part 301 and the lower snap-fit ​​part 302.

[0027] Please see Figure 4 and Figure 5 In some embodiments, the upper snap-fit ​​portion 301 includes an annular body 301a and a plurality of external threaded segments 301b. The plurality of external threaded segments 301b are disposed on the outer wall surface of the annular body 301a, and a first gap is reserved between adjacent external threaded segments 301b. The annular body 301a is assembled on the upper plate. Correspondingly, the lower snap-fit ​​portion 302 includes a main body segment 302a and a plurality of internal threaded segments 302b. An assembly groove is provided in the main body segment 302a. The plurality of internal threaded segments 302b are disposed on the inner wall surface of the assembly groove, and a second gap is reserved between adjacent internal threaded segments 302b. The size of the first gap is not less than the size of the internal threaded segment 302b, and the size of the second gap is not less than the size of the external threaded segment 301b. The internal threaded segments 302b and the external threaded segments 301b are threadedly connected to each other when in the snap-fit ​​position. The main body segment 302a is rotatably assembled in the lower plate 2.

[0028] It is understood that both the external thread segment 301b and the internal thread segment 302b are arc-shaped segments, and there are at least two of each. The arc lengths of both segments are the same. In the fixed state, the external thread segment 301b can be fully or partially threadedly connected to the internal thread segment 302b. In this embodiment, the external thread segment 301b is in full contact with the internal thread segment 302b. When it is necessary to separate the upper locking part 301 and the lower locking part 302, the lower locking part 302 is rotated to completely separate the external thread segment 301b from the internal thread segment 302b. The internal thread segment 302b can be completely located within the corresponding first spacing range, and the external thread segment 301b can be located within the corresponding second spacing range, thereby allowing the upper locking part 301 and the lower locking part 302 to separate. The structure of the upper locking part 301 and the lower locking part 302 is simple and can achieve quick fixing and quick separation between the two.

[0029] Please see Figure 2 , Figure 5 and Figure 6 In some embodiments, the main body segment 302a includes an upper columnar body 302a3, a lower columnar body 302a1, and a handle 302a4. The upper columnar body 302a3 is connected and fixed to the lower columnar body 302a1. A protrusion 302a2 is arranged around the outer wall surface of the upper columnar body 302a3. The handle 302a4 is assembled on the lower columnar body 302a1. Correspondingly, a corresponding assembly hole 202 is opened on the lower plate 2. An annular groove is arranged around the inner wall surface of the assembly hole 202. The protrusion 302a2 is rotatably assembled in the annular groove. The lower plate 2 is also provided with a notch 204 for the handle 302a4 to pass through and rotate. The assembly groove is opened in the upper columnar body 302a3.

[0030] It is understandable that the upper columnar body 302a3 and the lower columnar body 302a1 are connected to form a frustum shape, and the assembly hole 202 can also be frustum shaped to fit the main body section 302a. The size of the notch 204 is adapted to the angle that the lower locking part 302 needs to rotate. That is, the two ends of the notch 204 can respectively keep the upper locking part 301 and the lower locking part 302 in a separated and fixed state. The notch 204 not only provides rotation space for the handle 302a4, but also restricts the rotation range of the handle 302a4 at both ends. Moreover, OPEN and OFF can be marked on both sides of the notch 204 to indicate the separated and fixed states, respectively. The main body section 302a can be rotated by the handle 302a4. The surface of the protrusion 302a2 that contacts the annular groove can be an arc-shaped surface, so that the rotation between the protrusion 302a2 and the annular groove is smoother.

[0031] Please see Figure 1 and Figure 2In some embodiments, the upper plate 1 includes an upper plate body with a plurality of first through holes, and the quick-release component 3 is assembled between the upper plate body and the lower plate 2.

[0032] Understandably, the first perforation can be a threaded hole, which facilitates connection and fixation with the automotive parts to be processed.

[0033] Please see Figure 6 In some embodiments, the lower plate 2 includes a lower plate body 201 and a plurality of support legs 203. The plurality of support legs 203 are disposed on the lower plate body 201. The lower plate body 201 is also provided with a plurality of second through holes. Assembly holes 202 and notches 204 are disposed on the lower plate body 201. The quick-release component 3 is assembled between the upper plate 1 and the lower plate body 201.

[0034] It is understandable that the number of support legs 203 can be four. The lower plate 201 is rectangular, and the support legs 203 are located at the four corners of the lower plate 201. The second through hole can be used for the lower plate 201 to be connected to the bracket by bolts. The second through hole can be a bolt hole. The fixing bolt passes through the bracket and the second through hole in sequence. The lower plate 2 of this structure can effectively avoid interference with the rotation of the handle 302a4.

[0035] As described above, the quick-release structure provided by this utility model can quickly fix and disassemble automotive parts, and the operation is simple, thereby improving the overall processing efficiency.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
