[0031] Example

[0032] like Figure 1-Figure 5 As shown:

[0033] The present embodiment provides a connection device for elastically clamping between plates, comprising an embedded base 1 provided with a hollow cavity 11, a spring piece 2, a locker 3 and a limit clamping joint component 4; the spring piece 2 and the limit clamping joint component 4 in a retracted state (i.e., when squeezed by an external force or retracted and locked) are both located inside the embedded base 1; a first notch 111 penetrating the hollow cavity 11 is provided on one side of the embedded base 1, and a second notch 112 penetrating the hollow cavity 11 is provided on the other side of the embedded base 1; the locker 3 is installed in the second notch 112;

[0034] One end of the spring piece 2 is fixedly arranged on the fixed support structure inside the embedded base 1, and the other end of the spring piece 2 is connected to one side of the limit clamp joint component 4 facing the hollow cavity 11. The other side of the limit clamp joint component 4 elastically extends out of the first notch 111 under the elastic force of the spring piece 2 and is not locked in the hollow cavity 11 by the locker 3;

[0035] The locker 3 is used to lock the position-limiting clamping joint component 4 when the other side portion of the position-limiting clamping joint component 4 extends out of the first notch 111 .

[0036] In further optimization, specifically, the locker 3 can also be used to lock the position-limiting clamp joint component 4 when the other side portion of the position-limiting clamp joint component 4 is retracted.

[0037] Optimally, the lock 3 is a threaded fastener; the first notch 111 is a threaded through hole, and the lock 3 is screwed into the threaded through hole; when the other side of the limit card joint component 4 extends out of the first notch 111, the threaded fastener is screwed in so that the threaded fastener presses against one side of the limit card joint component 4, thereby locking the limit card joint component 4 in an extended state.

[0038] Optimally, the head of the locker 3 is used to cooperate with the screwdriver, and the tail end of the locker 3 is conical; an oblique extension structure 41 is provided on one side of the limiting clamp joint component 4; the oblique extension structure 41 is used to be pressed against and limited by the tail end of the locker 3 when the locking limiting clamp joint component 4 is in an extended state.

[0039] Optimally, the limiting card joint component 4 is a bullet-shaped one, one side of the limiting card joint component 4 is the tail of the limiting card joint component 4, and the other side of the limiting card joint component 4 is the head of the limiting card joint component 4; a recessed structure 42 is provided on the side of the middle part of the limiting card joint component 4, and when the limiting card joint component 4 is squeezed by external force and is located inside the embedded base 1, the threaded fastener is screwed in so that the threaded fastener presses against the recessed structure 42 of the limiting card joint component 4, thereby locking the limiting card joint component 4 in a retracted state.

[0040] Optimally, the recessed structure 42 is a cone-shaped pit.

[0041] Optimally, the cross-sectional structure of the spring piece 2 is in the shape of a "Z" rotated 90° counterclockwise.

[0042] Optimally, the outer wall of the embedded base 1 is provided with convex spines 12 for clamping the hole wall of the embedded hole of the plate.

[0043] The present embodiment further proposes a vertically spliced ​​plate combination using any of the above-described elastically snap-fit ​​connection devices, including the elastically snap-fit ​​connection device 100, a first plate 200 and a second plate 300; the first plate 200 and the second plate 300 are vertically connected to each other; the first plate 200 is provided with a plate embedded hole / groove at the junction of the two plates; the elastically snap-fit ​​connection device 100 is embedded in the plate embedded hole; the second plate 300 is provided with a snap-fit ​​hole / groove 3001 at the junction of the two plates, and the limiting snap-fit ​​joint component 4 extends into the snap-fit ​​hole / groove 3001.

[0044] Optimally, the number of the elastically snap-fitting connecting devices 100 between the plates is at least two, and the elastically snap-fitting connecting devices 100 between the plates are provided on both sides of the junction between the first plate 200 and the second plate 300, and snap-fitting holes / grooves 3001 are provided on both sides of the junction between the first plate 200 and the second plate 300.

[0045] In this embodiment, the elastically clamped connecting device 100 between the plates is compressed when it leaves the factory, and the locking device 3 is locked to prevent the elastic sheet 2 from being ejected (e.g. Figure 3 As shown), the installation process of the connecting device 100 for elastically clamping the plates is as follows:

[0046] Step 1: Press the elastically clamped connecting device 100 between the panels with the compressed spring sheet 2 originally provided by the factory into the movable layer panel (i.e. the first panel 200 or the second panel 300) with a notch (i.e. a pre-buried hole / groove in the panel);

[0047] Step 2: install the movable layer board equipped with the connecting device 100 for elastically clamping the boards into the cabinet with the movable layer hole (i.e., the clamping hole / slot 3001) opened; specifically, the installation details of step 1 are relatively flexible. When the spring sheet 2 is in the compressed state, the board can be pushed into the cabinet first and then the fastening screw (i.e., the locker 3) can be loosened, and the board can be moved up and down to make the head of the limit clamping joint component 4 slide into the movable layer hole (i.e., the clamping hole / slot 3001); when the spring sheet 2 is in the open state, the board can be pushed into the cabinet at an angle, and the board can be moved up and down to make the head of the limit clamping joint component 4 slide into the movable layer hole;

[0048] Step 3: Tighten the screw (i.e., the lock 3) to complete the installation.

[0049] The disassembly process of the elastically clamped connection device 100 between the plates is as follows: since the head of the limit clamp joint component 4 is inclined and smooth, the spring piece is easy to retract when the layer plate is forced upward, so if it needs to be removed, loosen the screws on the connector (i.e., the locker 3), move the layer plate upward and remove it.

[0050] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
