The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

As shown in fig. 1 to 5, the present embodiment provides a downward-turning door, which includes a door body 1, a link mechanism 2, a mounting structure 3, a support member 4, and a connecting member 5. The door body 1 is mounted on a mounting structure 3, and the mounting structure 3 is mounted at an opening of the cabinet or integrated with the cabinet so that the down-turned door can cover the opening of the cabinet.

Referring to fig. 1 to 2, the door body 1 is a rectangular metal plate, and four sides of the metal plate are bent inward to form bent portions 1a bent toward the support member 4. In order to prevent scraping, the sharp corner of the door body 1 is chamfered. The mounting structure 3 is provided with a left-right through opening. The mounting structure 3 is further provided with a groove 3a for accommodating the bent portion 1a of the door body 1, and the groove 3a extends leftward from the right side surface of the mounting structure 3. A rotating structure 3b is arranged in the groove 3a, and the bottom of the door body is rotatably arranged in the groove 3a through the rotating structure 3 b. In the present embodiment, the rotating structure 3b is a hinge. In addition, the rotating structure 3b may select a rotating shaft. The door body 1 is rotatably arranged by taking the bottom thereof as a rotating shaft. The cabinet body to which the mounting structure 3 is mounted is also provided with a locking device to lock the door 1 (not shown in the figures). The locking device may be selected from different kinds of existing locks, which are the prior art, and those skilled in the art may select the existing locks according to actual requirements, and the embodiment is not specifically limited.

The groove 3a has another function of limiting, and when the door body 1 rotates to be horizontal, the groove 3a supports the door body 1 to prevent the door body 1 from continuously turning over and injuring a user.

The support 4 is mounted on the cabinet and the support 4 is located above the linkage 2. The link mechanism 2 is arranged between the door body and the mounting mechanism 3.

Referring to fig. 3, the connector 5 is installed at the left side surface of the door body 1. The connecting member 5 is provided with a long hole 5a penetrating in the front and rear direction. An included angle is formed between the length direction of the long hole 5a and the door body 1. The included angle is A, and the range of A is more than or equal to 45 degrees and less than 90 degrees. The preferred a for this embodiment is 80.

One end of the link mechanism 2 is rotatably connected with the support member 4, the other end of the link mechanism 3 is connected with a shaft member 6, and the shaft member 6 is movably arranged in the long hole 5a. The shaft member 6 is axially rotatable within the elongated hole 5a and slidable along the elongated hole 5a. Referring to fig. 4, specifically, the link mechanism 2 includes a first link 21 and a second link 22. The first end of the first link 21 is rotatably connected to the support 4 by a pivot connection about which the first end of the first link 21 rotates. The second end of the first link 21 is connected to the rotational damper 23, and the first end of the second link 22 is connected to the rotational damper 23. The rotary damper 23 is a prior art, and the structure thereof will not be described in detail in this embodiment. The rotation damper 23 allows the first link 21 and the second link 22 to rotate with each other, and the rotation damper 23 provides resistance when the first link 21 and the second link 22 rotate with each other, so that the mutual rotation of the first link 21 and the second link 22 must require a user to provide an external force. The second end of the second link 22 is rotatably connected to the shaft member 6. Specifically, a hole is provided at the second end position of the second link 22, and the hole is fitted over the shaft member 6. In the present embodiment, the shaft member 6 is a rivet, and both ends of the rivet are provided with caps for limiting the position. Obviously, the shaft element 6 can also be a screw or a bolt.

When the door body 1 is vertical, the included angle between the first connecting rod 21 and the second connecting rod 22 is an acute angle, and when the door body 1 is horizontal, the included angle between the first connecting rod 21 and the second connecting rod 22 is an obtuse angle. When the door body 1 is turned downward by its own weight when the locking force of the door body 1 is removed, the link 5 moves to move the shaft member 6 from the first end to the second end of the elongated hole 5a, and the first link 21 and the second link 22 do not rotate with each other. The first end of the long hole 5a is the end close to the door body 1, and the second end of the long hole 5a is the other end far away from the door body 1.

As a further preferable mode of the above technical solution, the long hole 5a is a kidney-shaped hole, that is, both ends thereof are arc-shaped, so as to fit the shaft body of the shaft member 6, thereby reducing the probability of damage of the shaft member 6 when colliding with the long hole 5a, and improving the service life of the shaft member 6.

Referring to fig. 5, as a further preferred embodiment of the above technical solution, the connecting member 5 includes a first plate 51 and a second plate 52 perpendicular to each other. The first plate 51 is connected to the door body 1, and the elongated hole 5a is provided in the second plate 52. So guarantee the steadiness that connecting piece 5 is connected with door body 1.

The working state of the downward turning door is as follows:

(1) in the initial state, the door body 1 is vertical, the included angle between the first connecting rod 21 and the second connecting rod 22 is an acute angle, and the shaft member 6 is located at the first end of the long hole 5a.

(2) After the locking force of the door body 1 disappears, the door body 1 rotates clockwise under the action of the gravity of the door body 1, the connecting piece 5 moves relative to the shaft piece 6 when the door body 1 rotates until the shaft piece 6 is located at the second end of the long hole 5a, and at the moment, the shaft piece 6 pulls the inner wall of the long hole 5a to block the door body 1 from continuing to rotate. The rotational damper 23 then provides this pulling force.

(3) At this moment, the top of the door body 1 is separated from the opening of the mounting mechanism 3, the user pulls down the top of the door body 1 to overcome the resistance of the rotary damper 23, the door body 1 can continue to rotate, the first connecting rod 21 and the second connecting rod 22 rotate mutually in the process, the included angle between the first connecting rod 21 and the second connecting rod 22 is gradually increased, and when the door body 1 is horizontal, the included angle between the first connecting rod 21 and the second connecting rod 22 is an obtuse angle.

Note that, in the present embodiment, the number of the link mechanisms 2 is one. Obviously, the number of the link mechanisms 2 may also be two, all within the scope of the present invention.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
