[0030] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Reference Figures 2 to 5The sealing plate connecting member provided by the present invention comprises a base 1, a clamping ring 3 and a connecting rod 2. The sealing plate connecting member is used to connect a first plate and a second plate which are perpendicular to each other. The base 1 is provided with a mounting hole 10 for connecting with the first plate, and the mounting hole 10 cooperates with a wood screw to mount the base 1 on the first plate. The connecting rod 2 includes a plug-in rod 21, one end of which is provided with a screw rod 22 for connecting to the second plate, and the end face of the other end is provided with a mounting groove 20 for screwing the connecting rod. The base 1 is also provided with a plug-in hole 11 that matches the plug-in rod 21, and a slot 12 for accommodating the retaining ring 3 and limiting the axial movement of the retaining ring 3. The slot 12 is connected to the middle part of the plug-in hole 11. The retaining ring 3 includes an annular positioning portion 31, and an annular step portion 32 located on the inner periphery of the positioning portion 31. The inner diameter of the annular step portion 32 is smaller than the outer diameter of the plug-in rod 21. The annular step portion 32 is evenly distributed along the circumference with at least one notch 320, and this notch 320 divides the annular step portion 32 into a plurality of blades 321. When the snap ring 3 is embedded in the slot 12, the snap ring 3 is concentric with the plug hole 11, the plug rod 21 of the connecting rod 2 is inserted into the plug hole 11 of the base 1 and passes through the snap ring 3, and the plug rod 21 and the snap ring 3 are interference fit to lock the connecting rod 2 on the base 1.

[0032] The beneficial effect of the present invention is that when the plug-in rod 21 of the connecting rod 2 is inserted, the notch 320 and the blade 321 are deformed, and after the deformation, there is a force to restore them back, and this force plays a clamping role, thereby achieving a clamping effect.

[0033] Preferably, the notch 320 is U-shaped, and the blade 321 is trapezoidal, so that the plug-in rod 21 of the connecting rod 2 is more easily inserted into the clamping ring 3 .

[0034] The mounting groove 20 is a cross groove, a Pozigzag groove, a star groove or other suitable shapes.

[0035] The connecting rod 2 further includes a positioning step 23 disposed between the plug-in rod 21 and the screw rod 22 .

[0036] The plug hole 11 is a stepped hole, including a large hole and a small hole, the positioning step 23 is matched with the large hole 110 of the plug hole 11 , and the plug rod 21 is matched with the small hole of the plug hole 11 .

[0037] The clamping ring 3 is disc-shaped as a whole, which can increase the thickness of the clamping ring 3 and reduce the material used for the clamping ring 3 .

[0038] The base 1 includes a long strip-shaped base 13 , each of which has a mounting hole 10 on both sides of the base 13 in the length direction. The middle of the base 13 protrudes outward to form an inserting portion 14 , and the inserting portion 14 has the inserting hole 11 and the slot 12 .

[0039] The front side surface 15 of the plug-in portion 14 is an inclined surface, which can be used to quickly distinguish the front and back sides, making installation easier.

[0040] Reference Figures 4 to 5 The slot 12 includes a radial side wall 123, and a pair of parallel and opposite rear side walls 121 and front side walls 122. The inner diameter of the radial side wall 123 is adapted to the outer diameter of the snap ring 3, and the front side wall 122 is recessed inward to form a receiving groove 1220, and the diameter of the receiving groove 1220 is smaller than the diameter of the radial side wall 123. When the connecting rod 2 is inserted into the plug hole 11 and passes through the snap ring 3, the blades 321 on the snap ring 3 are deformed, and the receiving groove 1220 provides a deformation space for the blades 321 to play a locking role. If there is no receiving groove 1220, it can also play a clamping role. After the receiving groove 1220 is set, the clamping effect will be better.

[0041] Reference Fig.13 The multiple blades 321 on the snap ring 3 are inclined forward along the axial direction of the snap ring 3, so that the plug-in rod 21 of the connecting rod 2 can pass through more easily.

[0042] The sealing plate connector of the present invention can be used not only for connecting the left and right side plates of an embedded cabinet and the sealing plate, and for connecting the decorative door of a hallway cabinet and the layer plate, but also for connecting any two mutually perpendicular plates.

[0043] Reference Figures 6 to 12 , the installation steps of the sealing plate connector of the present invention are as follows:

[0044] (1) Install the base 1 on the side plate 02. When installing, make sure that the large hole in the stepped hole of the base 1 faces the sealing plate. Align the base 1 with the side plate 02. The base 1 cannot protrude outside the side plate 02.

[0045] (2) After alignment, use wood screws to fasten the base 1 to the side panel 02;

[0046] (3) Make a positioning mark on the sealing plate 01 to be connected: insert the plug rod 21 of the connecting rod 2 into the plug hole 11 of the base 1, align the sealing plate 01 with the side plate 02, and bring the sealing plate 01 close to the side plate 02, so that the tip of the screw of the connecting rod 2 pierces the sealing plate 01 and leaves a positioning mark A on the sealing plate 01;

[0047] (4) Take the connecting rod 2 out of the base 1, align the tip of the screw 22 of the connecting rod 2 with the marked position, and use an electric screwdriver to lock the connecting rod 2 into the sealing plate 01;

[0048] (5) Install the snap ring 3 into the slot 12 of the base 1;

[0049] (6) Align the cover plate 01 with the installed connecting rod 2 with the side plate 02 with the installed base, and align the plug-in rod 21 of the connecting rod 2 with the plug-in hole 11 on the base 1;

[0050] (7) After the holes are aligned, simply push the sealing plate 01 into the side plate 02 by hand, and clamp the connecting rod 2 with the clamping ring 3 to complete the installation.

[0051] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
