[0028] The present invention will be further described below in conjunction with the drawings and embodiments.

[0029] Refer to Figures 1-6 , a milk box connection and locking structure, comprising a coffee machine 10 and a milk box assembly 20. The milk box assembly 20 is provided with a steam input joint 210, and a locking groove 220 is provided on the side wall of the steam input joint 210. A joint cavity 110 is provided on one side wall of the coffee machine 10, and a steam output joint 120 that is inserted and matched with the steam input joint 210 is provided in the joint cavity 110;

[0030] A locking module 30 that can extend into the joint cavity 110 and be inserted into the locking groove 220 is provided on the coffee machine 10;

[0031] The locking module 30 includes a base 310 provided in the coffee machine 10. A locking rod 320 is slidably arranged left and right on the base 310. One end of the locking rod 320 close to the locking groove 220 can be slidably extended into the locking groove 220 to form a lock;

[0032] A connecting rod 340 is hinged to the end of the locking rod 320 away from the locking groove 220. A swing rod 350 is rotatably arranged on the base 310, and the swing rod 350 is hinged to the end of the connecting rod 340 away from the locking rod 320;

[0033] A knob 360 for driving the swing rod 350 to rotate along the axis 312 is provided on the swing rod 350.

[0034] In the above embodiments, the present utility model uses a rotary knob to achieve unlocking and locking. When unlocking and locking, the knob is driven to rotate forward or backward to drive the connecting rod of the swing rod, so as to drive the locking rod to slide relative to the base and achieve insertion into or detachment from the locking groove. The present utility model uses rotation as the operating part, which can avoid the problem of unlocking caused by accidental collision and has good locking stability.

[0035] See Figure 4 and Figure 5 , an arc-shaped limiting groove 311 is provided on the base 310, and the center of the arc-shaped limiting groove 311 is coaxially arranged with the axis 312;

[0036] A limiting shaft 370 is provided on the swing rod 350 or the connecting rod 340, and the limiting shaft 370 is movably inserted into the arc-shaped limiting groove 311.

[0037] The cooperation between the limiting shaft 370 and the arc-shaped limiting groove 311 can restrict the rotation angle of the swing rod 350 and the knob 360. When the locking rod 320 is in the fully locked position, the limiting shaft 370 is located at the head end of the arc-shaped limiting groove 311. When the locking rod 320 is in the fully unlocked position, the limiting shaft 370 is located at the tail end of the arc-shaped limiting groove 311.

[0038] See Figure 5 , the hinge axis of the swing rod 350 and the connecting rod 340 is coaxially arranged with the limiting shaft 370.

[0039] Furthermore, the limiting shaft 370 is provided on the swing rod 350, and a connecting shaft hole 341 is provided at one end of the connecting rod 340 away from the locking rod 320. The limiting shaft 370 is sequentially inserted into the connecting shaft hole 341 and the arc-shaped limiting groove 311;

[0040] The limiting shaft 370 is inserted into the connecting shaft hole 341 to form the hinge of the swing rod 350 and the connecting rod 340.

[0041] See Figure 5 , a positioning protrusion 510 is provided on the swing rod 350, and at least two positioning grooves 520 are provided on the base 310. The positioning grooves 520 are arranged along the circumference with the axis 312 as the center; when the swing rod 350 rotates, the positioning protrusion 510 can be embedded into any one of the positioning grooves 520 to form a positioning constraint.

[0042] The cooperation between the positioning protrusion 510 and the positioning groove 520 can restrict the swing rod 350 to prevent the swing rod 350 from rotating randomly.

[0043] In the locked state, the cooperation between the positioning protrusion 510 and the first positioning groove 520 can restrict the rotation of the swing rod 350.

[0044] In the unlocked state, the cooperation between the positioning protrusion 510 and the second positioning groove 520 can restrict the rotation of the swing rod 350.

[0045] See Figure 4 , a slot 130 is provided on one side of the engaging cavity 110 close to the locking rod 320, and the locking rod 320 can be inserted into the locking groove 220 through the slot 130.

[0046] See Figure 4 , a sliding seat 330 is slidably arranged left and right on the base 310, and the locking rod 320 is fixedly installed on the sliding seat 330.

[0047] See Figure 4 , the steam input joint 210 is inserted into the engaging cavity 110 from front to back, a micro switch 40 is arranged at the rear side of the engaging cavity 110, and the steam input joint 210 is provided with a triggering portion 230 that abuts against and triggers the micro switch 40. The arrangement of the micro switch 40 can ensure that the steam input joint 210 is fully inserted in place, avoiding potential safety hazards caused by incomplete insertion and assembly.

[0048] See Figure 2 , the locking module 30 is arranged inside the coffee machine 10, and the knob 360 is located outside the coffee machine 10 for controlling the entire locking module 30.
