[0025] In an embodiment of the present utility model, as Figures 1-5As shown, a hook self-locking structure includes an elastic member 1, a support member 2, and a cavity plate 3. The cavity plate 3 is provided with an installation opening 31. The support member 2 is used for placing a microwave oven bracket. The support member 2 is provided with a clamping portion 21. The support member 2 is installed in the installation opening 31 through the clamping portion 21. The elastic member 1 is installed on the cavity plate 3. The end of the elastic member 1 can be directly opposite to the installation opening 31. The elastic member 1 is used for clamping and fixing the clamping portion 21. In this embodiment, the numbers of the support member 2 and the elastic member 1 are both two. The elastic member 1 is specifically a spring plate. The cavity plate 3 is specifically two plate bodies on the left and right that form the microwave oven cavity. The elastic member 1 is installed on the inner wall or the outer wall of the cavity plate 3. If the elastic member 1 is installed on the inner wall of the cavity plate 3, the clamping end of the elastic member 1 needs to pass through the installation opening 31 and be located outside the installation opening 31. During installation, the elastic member 1 is installed on the cavity plate 3, and the clamping end of the elastic member 1 is aligned with the installation opening 31. Then, the support member 2 is installed on the cavity plate 3. Specifically, the clamping portion 21 of the support member 2 is passed through the installation opening 31 in the horizontal direction, and the clamping end of the elastic member 1 is pushed upward until the clamping end of the elastic member 1 is pushed up and then reset. At this time, the clamping end of the elastic member 1 abuts against the inner side of the clamping portion 21. At this time, the clamping end of the elastic member 1 plays a blocking role, preventing the clamping portion 21 from moving outwards, so that the elastic member 1 is clamped on the clamping convex block 21, and further clamping and fixing the support member 2 on the cavity plate 3. Through the elastic member 1, the support member 2, the clamping portion 21, the cavity plate 3, and the installation opening 31, the elastic structure of the elastic member 1 is adopted to realize clamping and fixing self-locking by pushing up the clamping portion 21 of the support member 2 and then resetting it. The installation is convenient and fast, achieving the effect of improving the installation efficiency of the support member 2.

[0026] As Figures 2-3As shown, a convex hook 211 is provided on the top surface of the card-loading portion 21. The elastic member 1 includes a mounting piece 11 and a swinging piece 12. The mounting piece 11 is mounted on the cavity plate 3, and the swinging piece 12 is swingably connected to the mounting piece 11. The swinging piece 12 is inclined and can abut against the convex hook 211. In this embodiment, the card-loading portion 21 is provided on the outer side of the support member 2, and the convex hook 211 protrudes upward from the top surface of the outer end of the card-loading portion 21. The mounting piece 11 and the swinging piece 12 are of an integrally formed structure. When the support member 2 is mounted on the cavity plate 3, specifically, the card-loading portion 21 is moved horizontally so that the card-loading portion 21 passes through the mounting opening 31, and the convex hook 211 pushes the swinging piece 12 upward. After the convex hook 211 moves to the outside of the swinging piece 12, the swinging piece 12 swings and resets under its own elastic structure. When the support member 2 has a tendency to move inward in the horizontal direction, the end of the swinging piece 12 abuts against the inside of the convex hook 211. At this time, the swinging piece 12 plays a blocking role and can prevent the support member 2 from driving the card-loading portion 21 to move inward.

[0027] As Figure 3 shown, the card-loading portion 21 is provided with an inclined surface 212, and the inclined surface 212 faces the end of the swinging piece 12. One end of the inclined surface 212 is connected to the inside of the convex hook 211, and the other end of the inclined surface 212 is connected to the top surface of the card-loading portion 21. In this embodiment, the inclined surface 212 is provided on the card-loading portion 21 so that the inclined surface 212 faces the lower end of the swinging piece 12, that is, the inclined surface 212 is parallel to the plane at the end of the lower end of the swinging piece 21. One end of the inclined surface 212 is connected to the inside of the convex hook 211, and the other end of the inclined surface 212 is connected to the top surface of the card-loading portion 21. When the swinging piece 12 abuts against the inside of the card-loading portion 21, specifically, the swinging piece 12 abuts against the inclined surface 212, and the plane at the end of the lower end of the swinging piece 12 can be completely attached to the inclined surface 212, that is, the end of the lower end of the swinging piece 12 can vertically abut against the inclined surface 212, so as to facilitate improving the blocking performance of the swinging piece 12 and prevent the card-loading portion 21 from being easily disengaged.

[0028] As Figure 3As shown, a groove 213 is provided on the bottom surface of the card-loading portion 21, and the inner bottom surface of the mounting opening 31 can be placed in the groove 213. In this embodiment, the groove 213 is formed by upward depression on the bottom surface of the card-loading portion 21. During installation, when the card-loading portion 21 moves horizontally towards the mounting opening 31, after the swing piece 12 is lifted and reset, at this time the groove 213 is directly opposite to the inner bottom surface of the mounting opening 31. Under the action of gravity, the support member 2 drives the card-loading portion 21 to fall downward until the inner bottom surface of the mounting opening 31 is placed in the groove 213, and at this time the installation is completed. The groove 213 can play a blocking role to prevent the card-loading portion 21 from loosening from the mounting opening 31, further improving the installation stability of the support member 2.

[0029] As Figure 2 shown, a placement block 22 is provided on the inner side of the support member 2, and a placement groove 221 is provided in the placement block 22. The placement groove 221 is used for placing a microwave oven bracket. In this embodiment, the placement block 22 is provided on the inner side of the support member 2, and the top surface of the placement block 22 is formed with the placement groove 221 by downward depression. The placement groove 221 is used for placing a microwave oven bracket. When taking and placing the microwave oven bracket, only need to place the bracket downward or pick it up upward, which is convenient and fast.

[0030] As Figure 2 shown, at least two placement blocks 22 are provided on the inner side of the support member 2. The plurality of placement blocks 22 are vertically arranged along the height direction of the support member 2, and the placement block 22 is provided with an arc surface 222. In this embodiment, two placement blocks 22 are provided on the inner side of the support member 2, and each placement block 22 is provided with two placement grooves 221, so that the support member 2 can place two microwave oven brackets. And an arc surface 222 is provided on the inner side of the bottom of each placement block 22. By providing the arc surface 222, the corners are reduced, so that the collision between the microwave oven bracket and the corners can be effectively reduced, thereby being deformed or damaged, which is beneficial to improving the service life of the microwave oven bracket.

[0031] As Figure 2 shown, at least two card-loading portions 21 are provided on the outer side of the support member 2. The plurality of card-loading portions 21 are evenly spaced along the height direction of the support member 2, and the number of the card-loading portions 21 is the same as the number of the elastic members 1. In this embodiment, two card-loading portions 21 are provided on the outer side of the support member 2, and the number of the card-loading portions 21 is the same as the number of the elastic members 1. Thus, the support member 2 is card-mounted on the cavity plate 3 through the plurality of card-loading portions 21 and the plurality of elastic members 1, with high load-bearing capacity and not easy to loosen and deform, which is beneficial to improving the installation stability of the support member 2.
