Description

Stamping buckle expansion bolt for hollow brick light brick Technical Field The utility model belongs to the technical field of bolts, and particularly relates to a stamping buckle expansion bolt for a hollow brick light brick. Background Expansion bolts are a special threaded connection used in securing pipe branches, hangers, brackets or equipment to walls, floors and columns. Chinese patent publication No. CN221665049U discloses an expansion bolt which comprises a forward buckle sleeve, a reverse buckle sleeve, a conical nut, a clamp, a nut and a screw rod, and is characterized in that the conical nut is screwed on the screw rod, the clamp on the conical nut is clamped into the reverse buckle sleeve, and the forward buckle sleeve and the reverse buckle sleeve are sleeved on the screw rod respectively to be screwed into the nut. The clip spring is arranged on the forward buckle sleeve and the reverse buckle sleeve. The utility model has the advantages of back buckling, difficult detachment after loosening and stability. The expansion bolts in the prior art are easy to misplace due to the fact that the snap springs are needed to clamp the sequential buckling sleeve and the reverse buckling sleeve during installation, so that the sequential buckling sleeve and the reverse buckling sleeve are inconvenient to use, the spring clamps are needed, and the cost is high. Disclosure of Invention The utility model aims to overcome the defects and provide the stamping buckle expansion bolt which is provided with reserved connection points during stamping, is free of positive and negative differences and dislocation, does not need spring clip connection, is convenient to use and low in cost and can be used for hollow brick light bricks. The aim and the main technical problems are achieved by adopting the following technical scheme: The utility model discloses a stamping sleeve expansion bolt for a hollow brick light brick, which consists of a sleeve A, a sleeve B, a clamp, a screw rod, a conical nut, a nut and a clamping groove, wherein the conical nut is screwed in the screw rod, the clamp on the conical nut is clamped in the clamping groove arranged on the sleeve A, the sleeve A and the sleeve B are sleeved on the screw rod respectively and screwed in the nut, and the sleeve A and the sleeve B are fixedly connected through a plurality of connecting points. The buckle sleeve B is provided with a clamping groove. One end of each of the buckle sleeve A and the buckle sleeve B is provided with an inclined buckle head. The buckle sleeve A is shorter than the buckle sleeve B, and can be exchanged up and down. Compared with the prior art, the utility model has obvious beneficial effects that the screw rod is fixedly connected with the buckle sleeve B through a plurality of connecting points by the buckle sleeve A, the conical nut is screwed in the screw rod, the clamp on the conical nut is clamped into the clamping groove arranged on the buckle sleeve A, and the buckle sleeve A and the buckle sleeve B are respectively sleeved on the screw rod and screwed in the screw cap. When the buckle sleeve A and the buckle sleeve B are stamped, a connecting point is reserved between the buckle sleeve A and the buckle sleeve B, the nut is moved, the nut pushes the buckle sleeve A, a plurality of connecting points between the buckle sleeve A and the buckle sleeve B are separated, the inclined surfaces of the buckle sleeve A and the buckle sleeve B are dislocated, the buckle sleeve A and the buckle sleeve B are obliquely protruded, the buckle heads of the buckle sleeve A and the buckle sleeve B are respectively clamped in the light brick holes or the hollow bricks, the expansion bolts are prevented from separating from the light brick holes or the hollow bricks, the spring clamp connection is not needed, the reserved connecting point is realized when the impact is realized, the buckle sleeve is not separated and positive and not misplaced, the spring clamp connection is not needed, the use is convenient, and the cost is low.
