Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a buckle quick-insertion structure. Background Art

[0002] As a limiting structure, buckles are widely used in various fields. They have the advantages of simple structure and easy use. However, existing buckles need to be disassembled when unlocking, and repeated disassembly and installation will cause the opening of the buckle to repeatedly expand to the maximum range, causing the elastic force of the buckle to fail, and there is a situation where the buckle becomes loose or even falls off automatically during use. In addition, the size of the buckle is generally small. When disassembled, it is easy to be lost or mixed with other parts and difficult to find, which brings certain troubles to use and maintenance. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a buckle structure which is easy and quick to unlock.

[0004] A buckle quick-insertion structure comprises a buckle, which is overall U-shaped and comprises clamping arms on both sides and a connecting body in the middle. The two clamping arms have elasticity for opening and restoring, so that locking and unlocking can be achieved.

[0005] Relative limiting protrusions are arranged between the two clamp arms. The two limiting protrusions form an opened unlocked state and a closed locked state through the opening and recovery between the two clamp arms, and can be inserted into some grooves to form a locking state.

[0006] The inner side of the buckle is provided with symmetrical unlocking inclined surfaces facing the opening. When the buckle is installed in the preset installation groove and is further pressed, the two clamping arms are squeezed and opened by the two unlocking inclined surfaces, and the two limiting protrusions are switched from the retracted and locked state to the open and unlocked state. The buckle is released, and the two clamping arms are restored, and the two limiting protrusions are switched from the open and unlocked state to the retracted and locked state.

[0007] The buckle quick-insertion structure provided by the utility model is provided with an unlocking inclined surface. When unlocking is needed, the buckle only needs to be pressed, and the two clamping arms can be pushed open by the unlocking inclined surface, so that the buckle is opened and unlocking is achieved. This unlocking method is not only easy to operate, but also does not require the buckle to be removed, which can prevent the buckle from being lost. On the other hand, the buckle can also be set to a one-way non-detachable or non-easy to disassemble structure, thereby avoiding the problem of loosening or automatic falling off.

[0008] Preferably, the limiting protrusion is also provided with a top-opening inclined surface facing the opening. When the buckle is installed into the mounting groove, the top-opening inclined surface can be squeezed to allow the buckle to open the opening, thereby facilitating installation.

[0009] Preferably, the unlocking inclined surface and the opening inclined surface are the same inclined surface, which can simplify the structure and reduce the difficulty of molding the buckle.

[0010] Preferably, the buckle quick-insertion structure also includes a docking outer tube and a docking inner tube, the mounting groove is arranged on the outer circumference of the docking outer tube, and two symmetrical clearance holes are arranged in the mounting groove. The docking inner tube is inserted into the docking outer tube, and is provided with a limiting groove aligned with the clearance hole. The buckle is installed in the mounting groove, and the limiting protrusion is inserted into the limiting groove through the clearance hole to form the retracted and locked state. At this time, the docking inner tube and the docking outer tube are relatively fixed in the axial direction. There is a compression gap between the inner side of the connecting body and the mounting groove. The buckle is pressed, and the two clamp arms are opened by squeezing the unlocking inclined surface of the mounting groove, and the limiting protrusion withdraws from the limiting groove to form the opened and unlocked state. At this time, the docking inner tube can be separated from the docking outer tube.

[0011] Preferably, the unlocking inclined surface is arranged on the outward side of the limiting protrusion, and the surface of the clearance hole opposite to the outward side of the limiting protrusion is a fixed inclined surface, and the two clamping arms are opened by the fixed inclined surface squeezing the unlocking inclined surface.

[0012] Preferably, the mounting groove is also U-shaped, which is more compatible with the buckle.

[0013] Preferably, the limiting groove is annular as a whole, so that in the locked state, the docking outer tube and the docking inner tube can rotate relative to each other.

[0014] Preferably, a guide structure for preventing misalignment is provided between the buckle and the installation slot, so as to prevent the buckle from deviating from the correct installation position when the buckle is pressed.

[0015] Preferably, the buckle is provided with a guide groove, and the mounting groove is provided with a guide protrusion, and the guide protrusion is inserted into the guide groove and can move relatively.

[0016] Preferably, the guide groove is arranged in the middle of the inner side of the connector and passes through both ends, so that the connector can have a larger deformation range.

[0017] Preferably, a guide slope is provided on one side of the limiting protrusion facing the insertion port of the docking outer tube, and when the docking inner tube is installed, there is no need to press the fastener again, and the two clamping arms can be directly inserted and pushed open by the guide slope.

[0018] From the above description of the utility model, it can be seen that the utility model has the following beneficial effects:

[0019] The buckle quick-insertion structure provided by the utility model is provided with an unlocking inclined surface. When unlocking is required, the buckle can be pressed to push open the two clamping arms through the unlocking inclined surface, so that the buckle is opened to achieve unlocking. This unlocking method is not only easy to operate, but also does not require the buckle to be removed, which can prevent the buckle from being lost.

[0020] The buckle provided by the utility model can be set to a one-way non-detachable or difficult to disassemble structure, thereby avoiding the problem of loosening or automatic falling off;

[0021] The unlocking inclined plane and the opening inclined plane are set to be the same inclined plane, which can simplify the structure and reduce the difficulty of forming the buckle;

[0022] A compression gap is reserved between the inner side of the connector and the mounting groove to provide a possibility for pressing the buckle;

[0023] A guide structure for preventing misalignment is also provided between the buckle and the installation slot, so as to prevent the buckle from deviating from the correct installation position when the buckle is pressed. BRIEF DESCRIPTION OF THE DRAWINGS
