Description

Technical Field

[0001] This utility model belongs to the field of display cabinet technology, specifically relating to a two-way opening display cabinet. Background Technology

[0002] To achieve double-sided opening, existing display cabinets typically use sliding doors or a double-door design. However, sliding doors generally only open to about 50% of their opening, while double doors require two separate openings to fully open the cabinet.

[0003] If a single-leaf cabinet door structure is used, the door is typically connected to the cabinet body by hinges, allowing only one-sided opening and not double-sided opening. To achieve double-sided opening of a single-leaf cabinet door, it is necessary to design a double-sided opening display cabinet. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0024] Example 1

[0025] like Figures 1 to 4 As shown, this embodiment designs a two-way opening display cabinet, including a cabinet body 1; a cabinet door 6 is provided at the cabinet opening on the front side of the cabinet body 1, and locking rods 61 are fixed on the left and right sides of the cabinet door 6; a lock groove is provided on both the left and right sides of the cabinet opening, and when the cabinet door 6 is closed, the two locking rods 61 are inserted into the corresponding lock grooves; a lock 7 is provided on the cabinet body 1, and the lock 7 includes two locking tongues 71, namely a left locking tongue and a right locking tongue, which can alternately extend into the lock groove to lock the two locking rods 61, or unlock one of the locking rods 61.

[0026] The cabinet opening is also provided with clearance grooves 11 on the left and right sides, so that the edge of the cabinet 1 can rotate into the clearance grooves 11 during the opening process.

[0027] Lock 7 is an existing linkage lock, which is located on the lower side of the cabinet opening. Extension rods can be connected to the left and right sides of the linkage lock. The left latch can be fixed to the left end of the linkage lock via the extension rod, and the left latch can also be fixed to the right end of the linkage lock via the extension rod.

[0028] Multi-bend connecting rods 72 are also provided at both ends of the linkage lock. The left latch consists of two parts, one upper and one lower, which are connected by a multi-bend connecting rod 72. The two left latches can lock the upper and lower ends of the latch rod 61 into the lock groove on the left side of the cabinet opening. The right latch also consists of two parts, one upper and one lower, which are connected by another multi-bend connecting rod 72. The two right latches can lock the upper and lower ends of the latch rod 61 into the lock groove on the right side of the cabinet opening.

[0029] The lock slot is a vertical slot, with two left locking tongues located on the upper and lower sides of the left lock slot of the cabinet opening, respectively, and two right locking tongues located on the upper and lower sides of the right lock slot of the cabinet opening, respectively.

[0030] Controlled by the linkage lock, the left latch can be partially inserted into the lock groove, fully inserted into the lock groove, or retracted from the lock groove. When the left latch is partially inserted into the lock groove, the right latch is also partially inserted into the lock groove; at this time, the latch rod 61 on the left side of the cabinet door 6 is locked in the lock groove on the left side of the cabinet opening by the left latch, and the latch rod 61 on the right side of the cabinet door 6 is locked in the lock groove on the right side of the cabinet opening by the right latch, and the cabinet door 6 cannot be opened from the left or right sides. When the left latch is fully inserted into the lock groove, the right latch retracts from the lock groove; at this time, the latch rod 61 on the left side of the cabinet door 6 is locked in the lock groove on the left side of the cabinet opening by the left latch, the latch rod 61 on the right side of the cabinet door 6 is unlocked, the lock groove is opened, and the cabinet door 6 can be opened to the left, such as... Figure 1 As shown. When the right latch is fully inserted into the lock groove, the left latch retracts from the lock groove; at this time, the latch bar 61 on the right side of the cabinet door 6 is locked in the lock groove on the right side of the cabinet opening by the right latch, the latch bar 61 on the left side of the cabinet door 6 is unlocked, the lock groove is opened, and the cabinet door 6 can be opened to the right, as shown. Figure 2 As shown.

[0031] Example 2

[0032] like Figure 1 Character Figure 5 As shown, based on the structure of Embodiment 1, both locking rods 61 are coaxially connected to sector gears 62, and a transverse sliding plate 2 is provided inside the cabinet 1. The strip-shaped teeth on the front sides of both ends of the transverse sliding plate 2 are linked with one of the sector gears 62 through a third coaxial gear 8.

[0033] like Figure 1 As shown, when the cabinet door 6 is opened to the left, the sector gear 62 on the left side of the cabinet door 6 drives the third coaxial gear 8 in the left lock groove to rotate counterclockwise, and the third coaxial gear 8 drives the transverse sliding plate 2 to move to the left; correspondingly, when the cabinet door 6 is closed, the transverse sliding plate 2 moves to the right.

[0034] like Figure 2 As shown, when the cabinet door 6 is opened to the right, the sector gear 62 on the right side of the cabinet door 6 drives the third coaxial gear 8 in the right lock groove to rotate clockwise, and the third coaxial gear 8 drives the transverse sliding plate 2 to move to the right; correspondingly, when the cabinet door 6 is closed, the transverse sliding plate 2 moves to the left.

[0035] Inside the cabinet 1, there is also a telescopic strip 5. The strip-shaped teeth on the rear side of the telescopic strip 5 are linked with the transverse strip 2 through the first coaxial gear 3 or the second coaxial gear 4. A telescopic display stand 9 is fixed on the telescopic strip 5. When the cabinet door 6 is opened, the telescopic display stand 9 is linked and extends forward.

[0036] The first coaxial gear 3 and the second coaxial gear 4 are located on the left and right sides of the telescopic strip 5, respectively, and are engaged with the strip-shaped teeth on the left and right sides of the telescopic strip 5. The transverse strip 2 can engage or disengage with the first coaxial gear 3 and the second coaxial gear 4.

[0037] When the transverse sliding plate 2 meshes with the first coaxial gear 3 and disengages from the second coaxial gear 4, moving the transverse sliding plate 2 to the left will cause the telescopic sliding plate 5 to move forward, and moving the transverse sliding plate 2 to the right will cause the telescopic sliding plate 5 to move backward. When the transverse sliding plate 2 disengages from the first coaxial gear 3 and meshes with the second coaxial gear 4, moving the transverse sliding plate 2 to the right will cause the telescopic sliding plate 5 to move forward, and moving the transverse sliding plate 2 to the left will cause the telescopic sliding plate 5 to move backward.

[0038] Due to the transmission relationship between components such as the first coaxial gear 3, the second coaxial gear 4, the third coaxial gear 8, the sector gear 62, the telescopic strip 5, and the transverse strip 2, the telescopic display stand 9 can extend forward during the opening of the cabinet door 6 and retract backward during the opening of the cabinet door 6.

[0039] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
