[0035] like Figure 1-7As shown, the present invention provides a delivery device, including an outer shell 1 and a door body 2, wherein a first side of the door body 2 is hinged to the outer shell 1, and a second side of the door body 2 opposite to the first side is provided with an arc-shaped lock hook 21, the lock hook 21 is buckled on the second side of the door body 2 and locked with a lock hole 13 on the outer shell 1, and a closed side of the lock hook 21 is gradually inclined upward and extends relative to an open side of the lock hook 21 to form a guide portion 213.

[0036] In an embodiment of the present invention, by setting the closed side of the lock hook 21 as a guide portion 213 that gradually extends upward and tilts, the guide portion 213 that extends upward and tilts can guide the lock hook 21 that is misaligned with the lock hole 13 to move upward during the door closing process and enter the lock hole 13 and lock with the lock hole 13, so that the lock hook 21 and the lock hole 13 can be locked without manually lifting the door body 2. While saving manpower, it can avoid the lock hook 21 colliding with the outer shell 1 and causing damage to the outer shell 1.

[0037] The guide portion 213 extends upwardly at an angle as a whole. As the door body 2 is continuously closed, the guide portion 213 moves upwardly to contact the bottom of the lock hole 13, and gradually enters the lock hole 13 from the bottom of the lock hole 13, so that the door body 2 is gradually lifted. After the door body 2 is lifted to a normal position, the door body 2 continues to be closed, and the entire lock hook 21 gradually enters the lock hole 13 and locks with the lock hole 13.

[0038] The door body 2 includes an inner frame 25 and an outer frame 24 which are interlocked. The inner frame 25 is provided with a mounting seat 251 which is flat. A locking hook 21 is provided on the side of the mounting seat 251 facing the outer shell 1 , that is, the locking hook 21 is engaged with the mounting seat 251 .

[0039] like Figure 8 As shown, the outer periphery of the door body 2 is provided with a plug-in protrusion 23 protruding toward the outer shell 1, and the size of the plug-in protrusion 23 gradually decreases from the door body 2 to the outer shell 1. The outer shell 1 is provided with a plug-in groove 16 with a notch facing the door body 2, and the small-sized end of the plug-in protrusion 23 is inserted into the plug-in groove 16. Specifically, the outer frame 24 of the door body 2 is provided with a plug-in protrusion 23, and the outer shell 1 can be used to position the door body 2 through the plug-in cooperation of the plug-in groove 16 and the plug-in protrusion 23, so as to enhance the assembly strength between the outer shell 1 and the door body 2, and reduce the assembly gap between the outer shell 1 and the door body 2, thereby enhancing the sealing between the outer shell 1 and the door body 2.

[0040] The dispensing device is used for washing equipment, which can be a washing machine, a dishwasher, etc. When the washing equipment is a washing machine, especially a drum washing machine, the drum washing machine includes a casing, an outer drum arranged in the casing, and an inner drum rotatably arranged in the outer drum, the outer drum is a water holding drum during washing, or the inner drum is a water holding drum during washing; the dispensing device has a dispensing port, a perforation 121 is provided on the casing, a liquid inlet of a dispensing pipeline is connected with the dispensing port of the dispensing device, the dispensing pipeline enters the casing through the perforation 121, and a liquid outlet of the dispensing pipeline is connected with the water holding drum.

[0041] like Figure 2-5 As shown, in the embodiment of the present invention, the locking hook 21 includes a bottom wall 211 and two groove side walls 211 formed by bending on two opposite sides of the bottom wall, each groove side wall 211 includes a first section wall 2121 extending horizontally and a second section wall 2122 connected to the bottom wall and extending upwardly obliquely relative to the first section wall, the two first section walls 2121 of the bottom wall 211 constitute the open side of the locking hook 21, and the two second section walls 2122 and the bottom wall 211 constitute the closed side of the locking hook 21.

[0042] In an embodiment of the present invention, preferably, the lock hook is a U-shaped structure, the bottom wall of the lock hook is arc-shaped and protrudes inwardly of the lock hook, and the two side walls of the lock hook are symmetrically arranged with the bottom wall of the lock hook as the center.

[0043] The open side of the lock hook 21 and the closed side of the lock hook 21 are distributed along the direction in which the lock hook 21 is locked with the lock hole 13; the first section wall 2121 extends horizontally, and the two first section walls 2121 are arranged horizontally rather than up and down, and the first end of each horizontally extended first section wall 2121 is respectively connected to the second side of the door body 2, and the space between the first ends of the two first section walls 2121 forms a notch of the lock hook 21, and the two first end walls constitute the open side of the lock hook 21, and the second end of each horizontally extended first section wall 2121 is bent upward to form a second section wall 2122 that gradually extends upward, and the bottom wall 211 is connected to the highest ends of the two second section walls 2122, and the bottom wall 211 is arc-shaped, and the bottom wall 211 protrudes out of the groove of the lock hook 21, and the arc connecting ends of the bottom wall 211 are respectively connected to the highest ends of the two second section walls 2122.

[0044] The guide portion 213 gradually moves upward, first the bottom wall 211 contacts the bottom of the lock hole 13, and then the second wall section 2122 contacts the bottom of the lock hole 13. As the guide portion 213 gradually moves upward, until the bottom end of the second wall section 2122 moves upward and breaks away from the bottom of the lock hole 13 and enters the lock hole 13, the guide portion 213 completes the guidance of the lock hook 21. At this time, the door body 2 is lifted to the normal position, and the door body 2 continues to be closed, so that the two first wall sections 2121, the two second wall sections 2122 and the bottom wall of the lock hook 21 can continue to move into the lock hole 13 and lock with the lock hole 13.

[0045] In the embodiment of the present invention, the locking hole 13 has an opening 131 for the locking hook 21 to enter the locking hole 13 , and an auxiliary guide portion 134 is provided in the opening 131 to guide the guide portion 213 into the locking hole 13 and lock the locking hole 13 .

[0046] In the embodiment of the present invention, when the lock hook 21 enters the lock hole 13, the auxiliary guide portion 134 provided in the opening 131 can guide the guide portion 213 to accelerate the upward movement of the guide portion 213 into the lock hole 13, thereby accelerating the lock hook 21 to enter the lock hole 13 and lock with the lock hole 13;

[0047] like Figure 4 and Figure 6 As shown, further, the opening 131 is square, and the inner wall of the opening 131 gradually narrows from the outside to the inside of the lock hole 13, so that the opening bottom wall 1311 which is gradually inclined from bottom to top forms an auxiliary guide portion 134.

[0048] Because the inner wall of the opening 131 gradually narrows from the outside to the inside of the lock hole 13, the bottom wall 1311 of the opening gradually tilts from the bottom to the top along the outside to the inside of the lock hole 13, and the auxiliary guide portion 134 is formed by the bottom wall 1311 of the opening. The guide portion 213 can move in accordance with the auxiliary guide portion during the process of moving upward into the lock hole 13, and the auxiliary guide portion 134 guides the guide portion 213 to quickly and accurately enter the lock hole 13 through the opening 131.

[0049] Furthermore, the lock hole 13 includes a first lock hole section 132 and a second lock hole section 133, the inner periphery of the first lock hole section 132 forms an opening 131, the opening side of the second lock hole section 133 is buckled with the outer periphery of the first lock hole section 132, and the size of the second lock hole section 133 gradually decreases from the first lock hole section 132 to the second lock hole section 133.

[0050] The second locking hole section 133 is in a square shape, and a corner is formed between the bottom wall and the top wall of the second locking hole section 133 . When the locking hole 13 and the locking hook 21 are locked, the bottom wall 211 of the locking hook 21 abuts against the corner.

[0051] The first lock hole section 132 and the second lock hole section 133 are distributed along the direction in which the lock hook 21 is locked with the lock hole 13, and the second lock hole section 133 is buckled on the outer periphery of the first lock hole section 132, and the size of the second lock hole section 133 is gradually reduced along the direction in which the lock hole 13 is locked, so that the size of the second lock hole section 133 on the side of the first lock hole section 132 is relatively large. It can be considered that the size of the front end of the second lock hole section 133 is relatively large, and the size of the rear end of the second lock hole section 133 is relatively small. Because the guide portion 213 gradually extends upward at an angle, the larger size of the front end of the second lock hole section 133 can provide enough space for the guide portion 213 to enter the second lock hole section 133. When the door body 2 is lifted to the normal position, the bottom wall 211 of the lock hook 21 will fit the top wall of the second lock hole section 133 and move into the lock hole 13. The inclined setting of the top wall of the second lock hole section 133 can guide the bottom wall 211 of the lock hook 21 to move into the lock hole 13 and abut against the corner.

[0052] Specifically, the shell 1 includes a shell 11 and a reinforcement plate 12 arranged on the shell 11, a lock seat 111 is arranged in the shell 11, a groove 112 is arranged on the lock seat 111, the lock seat 111 at the outer periphery of the groove 112 is fitted with the reinforcement plate 12, the groove 112 forms a second lock hole section 133, the reinforcement plate 12 extends up and down, and a through hole 121 is arranged on the reinforcement plate 12 facing the second lock hole section 133, and the through hole 121 forms a first lock hole section 132.

[0053] The reinforcing plate 12 can enhance the strength of the shell 11, and the reinforcing plate 12 can be detachably arranged on the shell 11; the first lock hole section 132 is arranged on the reinforcing plate 12, which can reduce damage to the outer shell 1; the first lock hole section 132 has openings 131 at both ends, and the second lock hole section 133 has an opening 131 at one end and a closed end, and the first lock hole section 132 and the second lock hole section 133 are arranged separately.

[0054] like Figure 7 As shown, in an embodiment of the present invention, a limiting column 22 is provided below the lock hook 21 of the door body 2 in the same extension direction as the first section wall 2121, and the length of the limiting column 22 extending to the second side of the outer shell 1 does not exceed the length of the guide portion 213 extending to the second side of the outer shell 1, and a limiting hole 14 is provided below the opening 131 of the lock hole 13 for inserting the end of the limiting column 22.

[0055] In the embodiment of the present invention, specifically, the limiting column 22 extends horizontally like the first section wall 2121, the limiting column 22 is located directly below the lock hook 21, and extends toward the door body 2 together with the lock hook 21, the limiting column 22 is not provided on the mounting seat 251, the limiting column 22 is provided on the inner frame 25, and the limiting column 22 is cylindrical;

[0056] The limiting hole 14 is a circular hole, and the limiting hole 14 is arranged below the opening 131 of the lock hole 13. The limiting hole 14 and the lock hole 13 are both arranged on the reinforcing plate 12, and the reinforcing plate 12 has a vertically extending plane plate. Further, the limiting hole 14 and the lock hole 13 are arranged on the plane plate, and the axial extension size of the limiting hole 14 and the lock hole 13 is the same. The limiting column 22 gradually approaches the limiting hole 14 as the door body 2 is closed and is inserted into the limiting hole 14;

[0057] The length of the limit column 22 extending toward the door body 2 is smaller than the length of the lock hook 21 extending toward the door body 2, which prevents the limit column 22 from being too long, so that the guide part 213 contacts the lock hole 13 first, and then the limit column 22 contacts the limit hole 14. During the movement of the limit column 22 in the limit hole 14, it limits the movement of the lock hook 21 in the lock hole 13, prevents the lock hook 21 from escaping from the lock hole 13, and improves the accuracy of locking the lock hook 21 with the lock hole 13.

[0058] Specifically, one axial end of the limiting hole 14 is a closed end, and the other end is an opening 131 end. The limiting column 22 is inserted into the limiting hole 14 through the opening 131 end of the limiting hole 14 and abuts against the closed end of the limiting hole 14. The opening 131 end of the limiting hole 14 is provided with a strip-shaped protrusion 15 protruding toward the limiting column 22. The strip-shaped protrusion 15 is recessed along the radial direction of the limiting hole 14 and toward the outside of the limiting hole 14 to form a guide groove 151, and part of the outer peripheral wall of the limiting column 22 abuts against the inner side of the guide groove 151.

[0059] When the limiting column 22 abuts against the closed end of the limiting hole 14, it indicates that the locking hook 21 and the locking hole 13 are locked; the guide groove 151 guides the limiting column 22 before entering the limiting hole 14, so that the limiting column 22 can accurately enter the limiting hole 14, further improving the locking accuracy of the locking hole 13 and the locking hook 21.

[0060] The guide groove 151 extends along the circumference of the limiting hole 14 , and the extending length is less than half of the circumferential length of the limiting hole 14 .

[0061] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form.
