[0036] Reference Figures 1 to 3 A locking mechanism according to a first aspect embodiment of the present invention includes a body 100, a barrel 110, and a connecting assembly 120. The body 100 is provided with a driving device for rotating the barrel 110, and the driving device is located at the bottom of the barrel 110. The driving device includes a driving shaft 101, and the driving shaft 101 has a connecting seat 102 for supporting the barrel 110 and abutting against the bottom of the barrel 110.

[0037] It is understood that the bottom of the barrel body 110 is provided with a mounting plate 111, and the mounting plate 111 is provided with a plurality of connecting pins 113 along its circumference. Each connecting pin 113 includes a base 115 and a fastener 114. The minimum outer diameter of the fastener 114 is larger than the maximum outer diameter of the base 115, so the fastener 114 protrudes outward radially along the base 115. It is understood that a pad 112 is also provided between the mounting plate 111 and the bottom wall of the barrel body 110, and the end of the fastener 114 facing away from the connecting assembly 120 is fixedly connected to the pad 112. That is, the base 115 is simultaneously fixed to both the pad 112 and the mounting plate 111, which helps to improve the connection stability between the connecting pins 113 and the barrel body 110. It is understood that the base 115 can be connected to the pad 112 and the mounting plate 111 by interference fit or thread.

[0038] It is understood that the connecting assembly 120 is threadedly connected to the connecting seat 102. The connecting assembly 120 includes a swivel plate 121 and a snap-on plate 122, with the swivel plate 121 threadedly connected to the connecting seat 102. Specifically, the inner circumferential wall of the swivel plate 121 has threads, and the outer circumferential wall of the connecting seat 102 also has threads. Further, the swivel plate 121 has a boss 123, and the snap-on plate 122 has a positioning groove 124, with the boss 123 embedded within the positioning groove 124. It is understood that the central axis of the boss 123 coincides with the rotation axis of the barrel body 110, and the outer circumferential wall of the boss 123 can engage with the inner circumferential wall of the positioning groove 124, thereby achieving center positioning of the snap-on plate 122 on the swivel plate 121 and preventing wobbling during rotation. Further, the snap-on plate 122 and the swivel plate 121 are fixed together by bolts.

[0039] It is understood that the buckle plate 122 has interconnected insertion holes 127 and fastening grooves 128, and has multiple insertion holes 127 and fastening grooves 128 along the circumference of the buckle plate 122. It is understood that the outer diameter of the insertion hole 127 is larger than the outer diameter of the fastener 114, and the inner diameter of the fastening groove 128 is smaller than the outer diameter of the fastener 114. More precisely, the minimum outer diameter of the insertion hole 127 is larger than the maximum outer diameter of the fastener 114, and the maximum inner diameter of the fastening groove 128 is smaller than the minimum outer diameter of the fastener 114. This allows the fastener 114 to be inserted into the insertion hole 127 and move into the fastening groove 128, thus fastening the fastener 114 to the fastening groove 128 and fixing the barrel body 110 to the connecting seat 102. The connection between the fastener 114 and the fastening groove 128 prevents loosening and improves the installation stability of the barrel body 110.

[0040] Reference Figure 3The inner wall of the fastening groove 128 near the rotation axis of the drive shaft 101 has a first positioning surface 125. When the fastener 114 is fastened to the fastening groove 128, the first positioning surface 125 can press against the outer peripheral wall of the base 115. Furthermore, the first positioning surface 125 is an arc surface, and the center of the first positioning surface 125 is located on the rotation axis of the barrel body 110. Thus, when the fastener 114 is fastened to the fastening groove 128, the first positioning surface 125 pressing against the outer peripheral wall of the base 115 can achieve concentric positioning of the barrel body 110 relative to the fastening plate 122, so that the rotation axis of the barrel body 110 coincides with the central axis of the fastening plate 122, the screw plate 121, and the connecting seat 102. This reduces the shaking of the barrel body 110 during rotation, which is beneficial to improving the stability of operation and reducing vibration, thereby reducing the possibility of the barrel body 110 loosening.

[0041] Furthermore, the end of the fastener 114 facing the barrel body 110 has a second positioning surface 116, and the fastening groove 128 extends circumferentially along the barrel body 110. When the fastener 114 is fastened to the fastening groove 128, the connecting pin 113 can move along the length direction of the fastening groove 128. The second positioning surface 116 can press against the bottom wall of the buckle plate 122, so that the buckle plate 122 applies a pulling force to the connecting pin 113, thereby fixing the barrel body 110 on the connecting seat 102, and eliminating the axial gap between the barrel body 110 and the connecting seat 102, reducing the possibility of loosening, and reducing vibration or abnormal noise.

[0042] Furthermore, the maximum outer diameter of the snap plate 122 is larger than the maximum outer diameter of the barrel body 110, thus facilitating installation and disassembly. Understandably, during the production and installation process, the snap plate 122 is first installed on the swivel plate 121, with the boss 123 embedded in the positioning groove 124, and the two are fixed together with bolts. Then, the swivel plate 121 is screwed onto the connecting seat 102, and the installation depth of the connecting assembly 120 on the connecting seat 102 is adjusted. Next, the barrel body 110 is placed on the connecting seat 102, and the connecting pin 113 is inserted into the insertion hole 127. The snap plate 122 and the barrel body 110 rotate relative to each other, moving the connecting pin 113 into the snap groove 128. When the second positioning surface 116 abuts against the bottom wall of the snap plate 122 and the bottom wall of the barrel body 110 presses against the top wall of the connecting seat 102, the installation of the barrel body 110 is achieved.

[0043] Understandably, during routine cleaning and disassembly, the connecting pin 113 can be disengaged from the snap-fit ​​groove 128 by rotating the buckle plate 122. When the connecting pin 113 can be pulled out from the insertion hole 127, the bucket body 110 can be disengaged from the connecting seat 102, thus achieving disassembly. The installation process is the reverse, and will not be described in detail here. This disassembly and assembly operation is simple and quick, which helps to improve the convenience of daily use.

[0044] According to an embodiment of the second aspect of this utility model, a dough mixer is provided, including the locking mechanism described above. It is understood that the dough mixer incorporates all the technical features of the locking mechanism, and therefore the dough mixer at least incorporates all the beneficial effects of the locking mechanism.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
