Description

Round iron sleeve structure of invisible connecting key Technical Field The utility model relates to the field of furniture manufacturing, in particular to a round iron sleeve structure of an invisible connecting key. Background The wardrobe is one kind of furniture and is assembled with wooden boards. In the wardrobe manufacturing process, in order to improve the aesthetic degree of furniture, adopt stealthy connecting key to connect when the concatenation of plank, realize seamless concatenation's effect, stealthy connecting key mainly comprises round iron cover structure and connecting rod structure, wherein round iron cover structure imbeds in the recess on the plank, cooperates the connecting rod structure to realize seamless connection. When the round iron sleeve structure is matched with the connecting rod structure for use, after the connecting rod is inserted into the round iron sleeve, the end head of the ejector rod pushes the round beads to move, so that the abutting rod is opened to abut against the groove wall, and the check block at the end part of the elastic limiting rod is used for checking the end part of the connecting rod, so that the abutting and fixing effects are realized. However, in the existing round iron sleeve structure, the round iron sleeve main body part and the connecting rod are not directly clamped, only the check block is utilized for limiting, the connection stability is poor, and the connecting rod and the round iron sleeve main body are not directly fixed, so that the situation of loosening and falling easily occurs, and the use effect is general. Disclosure of utility model The utility model mainly aims to provide a round iron sleeve structure of an invisible connecting key, which can effectively solve the problems in the background technology. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The utility model provides a round iron sleeve structure of stealthy connecting key, includes round iron sleeve main part, be provided with the through-hole in the round iron sleeve main part, and the tip of round iron sleeve main part is provided with the elasticity gag lever post, the tip of round iron sleeve main part is provided with the elasticity joint pole, and the end of elasticity joint pole is provided with the tight piece of support, install the chucking arch on the through-hole inner wall in the round iron sleeve main part, and be provided with the circular slot on the outer wall of round iron sleeve main part. Preferably, the circular iron sleeve main body is provided with an expansion joint, the lower end of the circular iron sleeve main body is provided with an assembly notch, and the assembly notch is distributed in an annular array on the circular iron sleeve main body. Preferably, the two elastic limiting rods are symmetrically arranged on the round iron sleeve main body, and the end parts of the elastic limiting rods are fixed with check blocks. Preferably, the two elastic clamping rods are symmetrically arranged on the round iron sleeve main body, and the elastic clamping rods are fixedly connected with the round iron sleeve main body. Preferably, the elastic limiting rods and the elastic clamping rods are distributed on the round iron sleeve main body in an annular staggered mode. Compared with the prior art, the invisible connecting key has the beneficial effects that the round iron sleeve structure is characterized in that the clamping protrusion facing the inner side is arranged on the round iron sleeve main body, and after the connecting rod is inserted into the round iron sleeve, the clamping protrusion is abutted against the outer wall of the connecting rod, so that a direct fixing effect exists between the round iron sleeve main body and the connecting rod, the stability of the connecting rod after being connected with the round iron sleeve main body is ensured, the use stability of the whole invisible connecting key can be improved by matching with the elastic limiting rod and the check block, the situation of loosening and falling is avoided, the round groove is arranged at the clamping protrusion part, the thickness consistency of the round iron sleeve main body and the clamping protrusion is ensured, and the use effect is ensured.
