Abstract

A slanted locking tongue connecting structure comprising a tongue connecting piece (1). The tongue connecting piece (1) comprises a tongue connecting piece part I (11) and a tongue connecting piece part II (12) arranged in at least one conjoined shape and two ends thereof respectively can be embedded into grooves of two connecting objects (3, and 4). The tongue connecting piece part I (11) and the tongue connecting piece part II (12) respectively have arranged on same side along the longitudinal direction thereof slanted faces (111, and 121) slanting in opposite directions. The two connecting objects (3, and 4) also have arranged thereon grooves (31, and 41) having an identical gradient and matching the tongue connecting piece part I (11) and the tongue connecting piece part II (12). The length of the grooves (31, and 41) is incrementally longer than the tongue connecting piece part I (11) and the tongue connecting piece part II (12). The connecting object (3) is embedded in the groove (31) via the tongue connecting piece part I (11) and allows the tongue connecting piece part I (11) to squeeze tightly into the groove (31) from the wide section thereof towards the narrow section. The groove (41) of the connecting object (4) is arranged on the tongue connecting piece part II (12) and allows the tongue connecting piece part II (12) to squeeze tightly into the groove (41) from the wide section thereof towards the narrow section. This allows for facilitated completion of splicing, reliable splicing, and convenient assembly and disassembly.

In order to make the connection more reliable, some structures for enhancing the connection reliability, such as the splicing part I and the splicing part II, respectively, are narrowed from the end-facing intermediate boundary to form a certain inclination, the splicing part I and The transverse body of the splicing portion II is disposed as a toothed surface, and the top line and the root line of the toothed surface are parallel to the end faces of the splicing portion I and the splicing portion II, respectively, and the groin lumen of the two connecting objects It is also provided as a serrated groove that is adapted to the toothed surface.

Or, the circumferences of the splicing portion I and the splicing portion II are respectively reduced from the end surface to the intermediate boundary to form a certain inclination, and the traverse member I and the splicing portion II are disposed as a smooth surface. The tongue and groove of the connecting object is also set to the dovetail groove which is adapted to the smooth surface.

Depending on the situation, a plurality of splicing members may be selected as one body, and the two connecting objects are also provided with a plurality of grooving grooves having the same number of splicing members.

The invention adopts the structure as described above, and in use, a connecting object is first inserted into the gutter through the splicing part I, and the splicing part I is squeezed to the narrow portion at the width of the gutter, and then Attach the groove of another connected object In the part II, the connecting object is squeezed to the narrow portion of the splicing part II to the narrow portion, thereby easily completing the splicing, and the splicing is reliable, and the loading and unloading is convenient. When disassembling, as long as the force is applied in the opposite direction, the splicing member can be moved to a wide position at a narrow position of the gutter. When moving to the widest position, the splicing member can be separated from the object without damaging the connected object. At the same time, the object is easy to disassemble and convenient to carry. The invention will now be further described with reference to the accompanying drawings.
