[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0033] like Figures 1 to 4 As shown, a shelf buckle that can automatically pop up includes a mounting plate 1 for mounting on the inner wall of a refrigerator. The mounting plate 1 extends vertically. An adjustable support block 2 is slidably provided on the mounting plate 1 along the length direction of the fixed plate. A vertical guide rail and a guide groove are provided between the mounting plate 1 and the adjustable support block 2, and the adjustable support block 2 slides up and down. A plurality of positioning supports 3 are provided on the mounting plate 1 along the length direction. The positioning supports 3 can be bosses or holes. A positioning block 4 that can be pressed against the positioning supports 3 to position the adjustable support block 2 is provided on the adjustable support block 2. The positioning block 4 can be driven to press against or leave the positioning support 3. The adjustable support block 2 is provided with an upper opening for one end of the shelf to be placed in a support groove 21 for supporting the shelf. In the embodiment, the support groove 21 is a U-shaped groove, and part of the shelf is pressed against the support groove 21. The adjustable support block 2 is rotatably provided with a shelf lock 5 that can be rotated into the opening of the support groove 21 to lock the shelf and a locking member 6 that can be locked with the shelf lock 5 to lock the shelf lock 5. The shelf lock 5 and the locking member 6 are metal parts. The shelf lock 5 is rotated to a horizontal position to lock the shelf. The adjustable support block 2 is provided with an elastic part 7 that can be squeezed and deformed by the locking member 6 when the locking member 6 is locked with the shelf lock 5 and can bounce the locking member 6 when the shelf lock 5 is pried to separate the shelf lock 5 from the locking member 6.

[0034] For the convenience of locking, when the locking member 6 locks the shelf lock buckle 5, the shelf lock buckle 5 is pressed under the locking member 6 and the locking member 6 forms an angle with the shelf lock buckle 5, so that a triangular support can be formed.

[0035] In order to facilitate installation, a mounting end 22 is provided at the upper end of one side wall of the support groove 21, and the shelf lock 5, the locking member 6, and the elastic part 7 are rotatably plugged into the mounting end 22, and the mounting end 22 is on the side close to the mounting plate 1. The elastic part 7 is an elastic sheet integrally formed and arranged on the adjustable support block 2, and the elastic sheet is reset by its own material, such as a plastic sheet. The locking member 6 is a U-shaped rod, and the elastic sheet is vertically extended and provided with two pieces. The two sides of the U-shaped mouth of the locking member 6 are respectively pressed on the two elastic sheets, and the mounting end 22 has a socket, and the two ends of the U-shaped mouth of the locking member 6 are bent and inserted into the socket. An air avoidance groove 23 is provided on the mounting end 22, and the elastic sheet is vertically extended and arranged in the air avoidance groove 23. When the elastic sheet is squeezed and deformed, it can bend toward the air avoidance groove 23, and the air avoidance groove 23 can also prevent the locking member 6 from rotating.

[0036] The shelf lock 5 includes two locking rods 51 that are relatively spaced apart. One end of the locking rod 51 is rotatably plugged into the adjustable support block 2. The mounting end 22 has a socket. One end of the locking rod 51 is bent and inserted into the socket. The socket of the locking rod 51 is lower than the socket of the locking member 6. The other end of the locking rod 51 is integrally connected with a U-shaped top buckle 52 that is relatively folded above the locking rod 51. The U-shaped top buckle 52 is relatively bent and located above the locking rod 51. When the locking member 6 is buckled with the shelf lock 5, one end of the locking member 6 presses against the end of the U-shaped top buckle 52. The locking member 6 is provided with a protrusion 61 that protrudes upward and is higher than the U-shaped top buckle 52. The protrusion 61 prevents the locking member 6 from being inserted between the U-shaped top buckle 52 and the locking rod 51. The adjustable support block 2 is provided with a positioning groove 24 for supporting the shelf lock buckle 5 when the shelf lock buckle 5 is in the state of locking the shelf. One end of the locking rod 51 extends out of the positioning groove 24, and one end of the U-shaped top buckle 52 on the locking rod 51 extends out of the positioning groove 24. Due to the supporting effect of the positioning groove 24, when one end of the U-shaped top buckle 52 is bent downward, the locking rod 51 will be deformed downward, and when released, the locking rod 51 will be reset upward. The side of the positioning groove 24 is provided with a supporting wall 25 that can support the shelf lock buckle 5 when the shelf lock buckle 5 is rotated to the unlocked state. When the shelf lock buckle 5 is rotated to the locked state, it is squeezed and slid into the positioning groove 24 with the shelf lock buckle 5. In the unlocked state, the shelf lock buckle 5 is pressed against the upper end of the supporting wall 25. For example, when the shelf lock buckle 5 is rotated to 60°, it is pressed against the upper end of the supporting wall 25. The upper end of the supporting wall 25 has a guide notch to facilitate the sliding guide when the shelf lock buckle 5 is squeezed with the supporting wall 25.

[0037] Embodiment 2, as Figure 5-7 As shown, the difference from the first embodiment is that the structure of the spring sheet is slightly different. Specifically, the thickness of the lower part of the spring sheet is greater than that of the upper part. The spring sheet is thinner at the bottom and the top, about 0.5mm at the top and about 0.8mm at the bottom, so that the spring sheet can be easily squeezed, but the strength is ensured. A positioning groove 71 is provided at the upper end of the spring sheet for the locking member 6 to be inserted into when the locking member 6 squeezes the spring sheet. The size of the positioning groove 71 is slightly larger than the diameter of the locking member 6, so that the locking member 6 can enter the positioning groove 71, and the locking member 6 is not easily squeezed relative to the spring sheet. Dislocation and deformation.

[0038] Embodiment three, as Figure 8-9 As shown, the difference from Example 2 is that the installation structure of the rotating shaft 62 of the locking member 6 is different. Specifically, a rotating shaft 62 is provided at the end of the locking member 6, and a rotating shaft hole 26 for the rotating shaft 62 is provided on the adjustable support block 2. The rotating shaft hole 26 is an eccentric hole whose center is deviated from the rotation center of the rotating shaft 62 toward the bottom side of the supporting groove 21. When the locking member 6 is pressed to rotate upward and reset, the rotating shaft rotates eccentrically due to the upward elastic force. During the rotation process, the rotating shaft 62 will be closer to the eccentric hole, thereby allowing the rotating shaft 62 to have more friction. Similarly, when the locking member 6 is rotated downward, since there is more space on the lower side of the eccentric hole (the bottom side of the supporting groove 21), the rotating shaft 62 rotates smoothly.

[0039] Embodiment 4, as Figure 10-11 As shown, the difference from the second embodiment is that a shaft hole 26 for inserting the end of the locking member 6 is provided on the adjustable support block 2, and a spring piece is provided on one side of the bottom end of the shaft hole 26, and the spring piece is a circular arc protrusion, which is tilted upward to support the locking member 6.

[0040] The above contents are further detailed descriptions of the present invention in combination with specific preferred technical solutions, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the utility model.
