[0036] In this embodiment, a rotating shaft is provided on the cabinet body 1, and a shaft sleeve 6 is provided at the upper end of the front door 11. The shaft sleeve 6 is sleeved on the outside of the rotating shaft and can rotate around the rotating shaft. The limit member 2 is fixedly connected to the shaft sleeve 6. The limit member 2 is located on the inner side of the front door 11 and extends backward and rotates synchronously with the front door 11.
[0037] There are various structures of the limiting member 2 and the driving member 4, which can be plate-shaped or rod-shaped.
[0038] Those skilled in the art should understand that the rotating shaft can be set on the cabinet 1 or on the front door 11, as long as the front door 11 can be rotatably connected to the cabinet 1. The rotating shaft can also be set in the upper middle part of the front door 11, or even in the lower middle part of the front door 11, or the rotating shaft can be set on the side of the front door 11, which can realize the flipping and opening of the front door 11, and can also adopt the control front door opening structure of the double-door display cabinet in the utility model. When the rotating shaft is set in the upper middle part or the lower middle part of the front door 11, it is sufficient to ensure that the part of the front door 11 flipped to the inside of the cabinet 1 does not affect the opening of the cabinet door. When the rotating shaft is set on the left or right side of the front door 11, the driving member 4 can still be set at the bottom or upper part of the shelf 5, or it can be set on the left side or right side of the cabinet 1.
[0039] A guide assembly is arranged between the driving member 4 and the inner wall of the cabinet 1, or between the driving member 4 and the outer surface of the shelf 5, and the guide assembly includes a guide groove 42 and a guide block 43. One of the guide groove 42 and the guide block 43 is arranged on the driving member 4, and the other is arranged on the inner wall of the cabinet 1 or the outer surface of the shelf 5.
[0040] In this embodiment, the driving member 4 is provided with a guide groove 42, and the lower end surface of the shelf 5 is provided with a bolt as a guide block 43, the screw rod of the bolt passes through the guide groove 42 from bottom to top and is fixed to the shelf 5, and the bolt cap of the bolt abuts against the lower surface of the driving member 4, thereby positioning and installing the driving member 4 on the lower surface of the shelf 5. Similarly, the screw rod of the bolt passes through the guide groove 42 from bottom to top and is fixed to the inner top surface of the cabinet 1, and the bolt cap of the bolt abuts against the lower surface of the driving member 4, thereby positioning and installing the driving member 4 on the inner top surface of the cabinet 1, and the distance of the forward and backward movement of the driving member 4 is limited by the length of the guide groove 42.
[0041] An accommodating space 8 with an opening is provided on at least one of the inner side surface of the cabinet 1, the bottom of the cabinet 1, the top of the cabinet 1, and the shelf 5. A pivot shaft 7 is fixedly installed in the accommodating space 8. The locking block 3 is sleeved on the outer side of the pivot shaft 7 and can rotate around the pivot shaft 7. Part of the locking block 3 extends to the outside of the opening and is then inserted into the locking hole 21.
[0042] Specifically, the rear side of the portion of the lock block 3 extending out of the opening has a guide surface 31, which can be a guide plane or a guide arc surface. The driving member 4 moves forward to push the guide surface 31 to rotate the lock block 3 out of the lock hole 21. The front end of the portion of the lock block 3 extending out of the opening has a lock hook 32, which can be inserted into the lock hole 21. In this embodiment, the pivot shaft 7 extends horizontally to the left and right. From the cross-sectional view, after the lock block 3 rotates clockwise around the pivot shaft 7, the lock hook 32 can be inserted into the lock hole 21. The lock block 3 rotates counterclockwise to make the lock hook 32 disengage from the lock hole 21.
[0043] Alternatively, the front side of the locking block 3 extending out of the opening has a guide surface 31 , and the rear side of the locking block 3 extending out of the opening has a locking hook 32 , and the driving member 4 moves backward to push the guide surface 31 to rotate the locking hook 32 out of the locking hole 21 .
[0044] In this embodiment, in order to make the lock hook 32 better cooperate with the lock hole 21, an arc-shaped avoidance groove 34 is provided on the lock block 3, and the front-to-back width of the avoidance groove 34 is greater than the distance from the lock hole 21 to the rear end of the limiter 2.
[0045] In order to keep the locking block 3 inserted in the locking hole 21, a compression spring 9 is provided between the inner bottom surface of the accommodating space 8 and the rear end of the locking block 3. The compression spring 9 lifts the rear end of the locking block 3 upward, thereby causing the front end of the locking block 3 to flip downward and keep the locking hook 32 inserted in the locking hole 21.
[0046] Specifically, a positioning column 33 is provided on the locking block 3, and a compression spring 9 is sleeved on the outside of the positioning column 33. One end of the compression spring 9 abuts against the locking block 3, and the other end abuts against the inner bottom wall of the accommodating space 8. The positioning column 33 and the lock hook 32 are both located on the lower side of the locking block and extend downward.
[0047] Those skilled in the art should understand that there is a compression spring 9 between the inner wall of the accommodating space 8 and the locking block 3. As long as the locking block 3 can be kept inserted in the locking hole 21, the compression spring 9 can also be located at the end of the locking block 3 having the locking hook 32. At this time, the compression spring 9 can be located on the upper side of the locking block 3, with one end of the compression spring 9 pressing downward against the locking block 3 and the other end pressing against the inner top wall of the accommodating space 8, thereby pressing the front end of the locking block 3 downward so that the locking hook 32 is inserted in the locking hole 21.
[0048] Embodiment 2,
[0049] A front door opening structure for a display cabinet is different from Example 1 in that the movement mode of the driving member 4 is different. In this embodiment, the driving member 4 rotates, that is, a positioning hole can be set in the middle of the driving member 4, and then it is installed at the bottom of the shelf through the positioning pin shaft. The driving member 4 rotates around the positioning pin shaft. During the rotation process, the driving member 4 pushes the guide surface 31 of the locking block 3, so that the locking block 3 rotates into the accommodating space 8, thereby disengaging the lock hook 32 from the lock hole 21.
[0050] Embodiment 3,
[0051] A display cabinet with a front door opening structure, combined with Figure 5-6 As shown, the difference from Embodiment 1 is that the pivot shaft 7 in this embodiment is arranged on the inner surface of the cabinet 1 or the outer side of the shelf 5, and the inner surface of the cabinet 1 includes the inner top surface of the cabinet 1, the inner bottom surface of the cabinet 1, the inner left side surface of the cabinet 1 and the inner right side surface of the cabinet 1. The positioning column 33 and the lock hook 32 on the lock block 3 are located on the same side of the lock block 3, that is, they are both located on the upper side, lower side, left side or right side of the lock block 3.
[0052] In the natural initial state, the locking block 3 is separated from the locking hole 21 . When the driving member 4 moves and drives the locking block 3 to rotate, the locking block 3 is inserted into the locking hole 21 .
[0053] Specifically, the lock hook 32 and the guide surface 31 are located on the same side of the lock block 3, which is located on the side close to the shelf 5 and the inner surface of the cabinet 1. As shown in the figure, the lock block 3 is located on the lower surface of the shelf 5, the lock hook 32 is located at the front end of the upper surface of the lock block 3 and extends upward, and the guide surface 31 is located at the rear end of the upper surface of the lock hook 32. The positioning column 33 is located on the side of the pivot shaft 7 close to the lock hook 32, and the positioning column 33 is arranged upward, and the compression spring 9 is sleeved on the outer side of the positioning column 33, one end of the compression spring 9 is against the lock block, and the other end of the compression spring 9 is against the lower surface of the shelf 5. The compression spring 9 applies downward pressure to the lock block 3, so that the lock hook 32 is kept downwardly disengaged from the lock hole 21 in a natural state, and the front door 11 can be opened freely. The driving member 4 moves forward and abuts against the guide surface 31, thereby driving the rear end of the lock block 3 to flip downward, and the lock hook 32 is flipped upward and inserted into the lock hole 21, and the front door 11 cannot be opened.
