Description

Technical field

[0001] The present utility model relates to the technical field of furniture fittings, in particular an elastic deflection structure for a rotary and sliding mechanism. State of the art

[0002] Corner rotary cabinets are widely used in interior spaces due to their efficient use of corner space. In rotary cabinets with a push-to-open function, the rotation and sliding mechanism typically comprises a rotating plate with a sliding groove and a locking plate with a connecting pin. To achieve push-to-open release, a relief groove is usually provided at the end of the sliding groove, allowing the connecting pin a short free path during the initial phase of pushing to trigger the internal locking release mechanism.

[0003] However, the presence of this offset groove leads to a significant problem: when the rotating cabinet is fully closed, the connecting pin rests precisely at the end of the sliding groove. Since the offset groove lacks a load-bearing wall, a gap exists between the connecting pin and the sliding groove wall. This results in the cabinet body lacking radial support when closed, causing it to wobble slightly, which compromises operational stability and noise reduction. Therefore, there is an urgent need for an improved solution that eliminates these instability factors when closed while maintaining the pressure-release function. Content of the utility model

[0004] To achieve the aforementioned objective, the present utility model employs the following technical solution: An elastic deflection structure for a rotary and sliding mechanism, comprising a fixing plate and a rotating plate, wherein a sliding groove is formed on the surface of the rotating plate facing the fixing plate, and a connecting pin projecting into the sliding groove is fixedly arranged on the fixing plate. A deflection cavity is formed at the end of the sliding groove and is connected to the sliding groove. A locking block is movably arranged in the deflection cavity, and an elastic element is also provided in the deflection cavity, which imparts a restoring force to the locking block. When the connecting pin moves to the end of the sliding groove and presses against the locking block, the locking block can overcome the force exerted by the elastic element and retract into the deflection cavity.

[0005] Preferably, the locking block is rotatably arranged in the escape cavity. Preferably, in the initial state, the outer surface of the locking block facing the sliding groove forms a continuous guide surface together with the inner wall of the sliding groove.

[0006] Preferably, the elastic element is a torsion spring, wherein a receiving groove is formed in the deflection cavity, the torsion spring is received in the receiving groove and rests with one end on the wall surface of the receiving groove and with the other end on the locking block.

[0007] Preferably, the outer surface of the locking block facing the sliding groove is designed as a guide arc surface.

[0008] The advantageous effects of the present utility model are as follows: Due to the design with the movable locking block, when the cabinet door is closed, the locking block and the sliding groove wall form a continuous support surface, thereby completely eliminating the wobble gap caused by the deflection groove. When opening by pushing, the locking block can deflect evenly, so that the release function is not impaired.

[0010] With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig.Section 5 of the present utility model provides an elastic deflection structure for a rotation and sliding mechanism, comprising a fixing plate 10 and a rotating plate 20. The fixing plate 10 serves to connect to an external fixing cabinet body, and the rotating plate 20 serves to connect to an internal rotating cabinet body. A sliding groove 201 is formed on the surface of the rotating plate 20 facing the fixing plate 10, and a connecting pin 30 is fixedly arranged on the fixing plate 10, at the end of which a sliding roller is attached that projects into the sliding groove 201. When the rotating cabinet body moves, the sliding roller rolls in the sliding groove 201. Alternatively, the end of the connecting pin 30 can also project directly into the sliding groove 201 and slide with it, thereby guiding the rotating plate 20 (i.e., the rotating cabinet body) and controlling its rotation and sliding movement relative to the fixing plate 10 along a predetermined path.

[0011] At the end of the sliding groove 201, a deflection cavity 202 is formed, which is directly connected to the sliding groove 201. A movable locking block 40 and an elastic element 50, which gives the locking block 40 a restoring elasticity, are mounted in the deflection cavity 202.

[0012] In the present embodiment, the locking block 40 is rotatably mounted in the clearance cavity 202 by means of a pivot axis 60. The elastic element 50 is preferably a torsion spring which is received in a receiving groove 203 provided on the inner wall of the clearance cavity 202. One end of the torsion spring rests firmly against the side wall of the receiving groove 203, the other end rests against the side surface of the locking block 40 facing the interior of the clearance cavity 202. The torsion spring exerts a continuous torque on the locking block 40, which gives it an elastic tendency to rotate out of the clearance cavity 202.

[0013] Under the action of the torsion spring, the locking block 40 assumes a stable initial position. In this initial position (corresponding to the fully closed state of the cabinet door), the outer surface of the locking block 40 facing the sliding groove 201 is flush with the curved inner wall of the sliding groove 201 and together they form a continuous, uninterrupted guide surface. In this state, the connecting pin 30 located at the end of the sliding groove 201 is tightly supported by this complete guide surface, has no radial play, and thus ensures absolute stability when the cabinet door is closed without any wobbling.

[0014] When the user pushes the cabinet door to open it, the rotary plate 20 instantly experiences a slight initial displacement, causing the connecting pin 30 to move to the end of the sliding groove 201 and press against the locking block 40. The pressure force of the connecting pin 30 overcomes the torque of the torsion spring and forces the locking block 40 to rotate about its pivot axis into the interior of the clearance cavity 202, thus retracting into the clearance cavity 202 and allowing the connecting pin 30 to move freely. This clearance movement ensures that the pressure-release function can be realized.

[0015] To make the movement of the connecting pin 30 more uniform and smooth when touching and pressing the locking block 40, a guide arc surface 41 can be formed on the outer surface of the locking block 40. This guide arc surface 41 transforms the contact from a point into a line, so that the force transmission is smoother.

[0016] After the pressure release is complete, when the cabinet door begins to open or is closed again and the connecting pin 30 leaves the area of ​​the escape cavity 202, the locking block 40 automatically rotates outwards under the drive of the torsion spring and quickly returns to the initial position to form a complete support surface again together with the inner wall of the sliding groove and thus be ready for the stable state after the next closing. Summary of the operating principle:

[0017] Stable closing phase: The locking block 40 is in the starting position under the action of the elastic element 50, its outer surface together with the inner wall of the sliding groove 201 forming a continuous guide surface and providing full support to the connecting pin 30, thereby eliminating wobbling.

[0018] Pressure release phase: The connecting pin 30 moves under pressure to the end and pushes the locking block 40, which overcomes the spring force and retracts into the escape cavity 202, thereby realizing the required movement escape.

[0019] Automatic reset phase: After the pressure is removed, the locking block 40 automatically returns to its initial position under the action of the elastic element 50 and restores the support state.
