DETAILED DESCRIPTION

[0029] The utility model is further described in detail below with reference to the accompanying drawings. A cabinet layer connecting piece includes:

[0030] A connector body 1, the connector body 1 is installed in the installation holes 3 at the left and right ends of the layer plate 2, the interior of the connector body 1 is hollow to form a receiving cavity 4, and the receiving cavity 4 is set through the outer end surface of the connector body 1;

[0031] The elastic locking tongue 5 is axially slidably installed in the accommodating cavity 4, and its head is always pushed out of the accommodating cavity 4 by the elastic device, and inserted into the locking hole 7 on the cabinet body 6 to fix the layer board 2 on the cabinet body 6;

[0032] The upper end surface of the elastic locking tongue 5 is provided with a guiding inclined surface 51 , and the guiding inclined surface 51 and the locking hole 7 squeeze and drive the elastic locking tongue 5 to retract inwards.

[0033] In one of the embodiments: the accommodating cavity 4 is a blind hole penetrating the outer end surface of the connector body 1 , and the elastic device is a spring 8 installed at the bottom of the blind hole, and the spring 8 is supported on the inner end surface of the elastic locking tongue 5 .

[0034] In one embodiment, a guide column 52 is extended backward from the inner end surface of the elastic locking tongue 5, the outer end of the spring 8 is looped on the guide column 52, and the inner end of the spring 8 is pressed against the bottom of the blind hole.

[0035] In one embodiment, the guide slope 51 is arranged to be gradually raised and tilted from front to back.

[0036] In one embodiment, the lower portion of the elastic locking tongue 5 is a supporting plane 53 , and the supporting plane 53 is supported on the bottom of the locking hole 7 .

[0037] In one embodiment, a plurality of inwardly recessed locking areas 54 are provided on the column of the elastic locking tongue 5 , and elastic barbs 41 are provided in the accommodating cavity 4 and inserted into the locking areas 54 to limit the axial movement of the elastic locking tongue 5 .

[0038] In one embodiment, the elastic barb 41 is disposed in a clearance groove 42 on the cylindrical surface of the connector body 1 , and the tail of the elastic barb 41 protrudes upward and extends out of the outer cylindrical surface of the connector body 1 .

[0039] In one of the embodiments: the outer cylindrical surface of the connector body 1 is further provided with a plurality of anti-rotation bosses 9 protruding from the cylindrical surface.

[0040] Working principle: Before installing this product, it is necessary to set concave mounting holes on the left and right end faces of the layer board, and insert the connector into the mounting holes for fixing. When fixing, it is necessary to control its installation direction so that the guide slope of the elastic lock tongue is installed upward. After installation, the anti-rotation boss 9 is clamped in the mounting hole, and the friction between it and the mounting hole is used to prevent the connector from rotating and loosening during use.

[0041] The connector body 1 in this case is the main bearing part of the connection system, and the body is installed in the installation holes 3 at the left and right ends of the layer board 2. The connector body 1 is hollow inside, forming a receiving cavity 4 that runs through its outer end surface. This receiving cavity 4 provides space for installing the elastic locking tongue 5, and the through design allows the elastic locking tongue 5 to extend out of the outer end surface of the body and slide freely.

[0042] During the installation of the shelf, the shelf is placed at an angle, the elastic locking tongue on one side is inserted into the locking hole, and then the shelf is placed flat, the elastic locking tongue and the cabinet body are pressed against each other and retracted inward, and when the shelf 2 is placed at a predetermined position of the cabinet body 6, the head of the elastic locking tongue 5 will naturally be inserted into the locking hole 7 on the cabinet body 6. Since the lower part of the elastic locking tongue 5 is a supporting plane 53, the supporting plane 53 is supported on the bottom of the locking hole 7, which plays a good supporting role for the shelf.

[0043] When the user needs to remove the layer board, he lifts the layer board upwards. At this time, the guide slope 51 will contact the upper inner wall of the lock hole 7 and be squeezed, pushing the elastic lock tongue 5 to retract inward, so that the elastic lock tongue is separated from the lock hole, and the layer board can be easily removed.

[0044] When the layer plate is removed, the elastic locking tongue loses external obstruction, and the spring 8 releases its elastic force to push the elastic locking tongue 5 out, so that its head extends out of the accommodating cavity 4, in preparation for re-installation.

[0045] Compared with the traditional technology, since the elastic lock tongue 5 has a guiding slope, it can be installed with a sliding property by pressing upward. The user can push the shelf upward to withdraw the head of the elastic lock tongue 5 from the lock hole 7, thereby separating the shelf 2 from the cabinet body 6, realizing the free disassembly and adjustment of the shelf, and greatly improving the convenience of use.

[0046] In order to limit the movement of the elastic locking tongue, in this case, a plurality of recessed locking areas 54 are provided on the elastic locking tongue 5, and elastic barbs 41 are correspondingly provided in the accommodating cavity 4. These barbs are clamped in the locking area 54 to limit the axial movement of the elastic locking tongue 5. This design ensures that the elastic locking tongue 5 slides within a specific range, thereby ensuring the reliability and safety of the locking.

[0047] In summary, the cabinet layer board connector of the utility model realizes the stable installation of the layer board, the hidden and beautiful design and the convenient disassembly function through the above structure and working principle. Its innovative design not only solves the shortcomings of the existing technology, but also provides an efficient, convenient and beautiful layer board connection solution, so it can be widely promoted and used.

[0048] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the claims created by the utility model.
