Description

Technical Field

[0001] This utility model belongs to the field of bolt technology, specifically relating to a stamped expansion bolt that can be used for hollow bricks and lightweight bricks. Background Technology

[0002] Expansion bolts are special threaded connectors used to fix pipe supports, hangers, brackets, or equipment to walls, floors, or columns. Chinese Patent No. CN221665049U discloses an expansion bolt comprising a forward-threaded sleeve, a reverse-threaded sleeve, a conical nut, a clip, a nut, and a bolt. The conical nut is screwed into the bolt, and the clip on the conical nut engages with the reverse-threaded sleeve. The forward-threaded sleeve and the reverse-threaded sleeve are respectively fitted onto the bolt and screwed into the nut. Spring clips are installed on the forward-threaded sleeve and the reverse-threaded sleeve. This invention features a reverse-threaded design, making it less prone to detachment after loosening, thus providing stability. In contrast, existing expansion bolt forward-threaded sleeves and reverse-threaded sleeves require spring clips to hold them in place during installation, which can lead to misalignment, inconvenience, and high cost. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a stamping expansion bolt for hollow bricks and lightweight bricks with a pre-reserved connection point during stamping, a sleeve that is not divided into front and back, will not be misaligned, does not require spring clip connection, is easy to use, and has a low cost.

[0004] The purpose of this utility model and the solution to its main technical problem are achieved by the following technical solution:

[0005] This utility model discloses a stamped expansion bolt for hollow bricks and lightweight bricks, which consists of a sleeve A, a sleeve B, a clip, a screw, a conical nut, a nut, and a groove. The conical nut is screwed into the screw, and the clip on the conical nut is engaged with the groove on the sleeve A. Sleeves A and B are respectively fitted onto the screw and screwed into the nut. Sleeves A and B are fixedly connected by several connection points.

[0006] The buckle B is provided with a slot.

[0007] Both buckle A and buckle B have an inclined buckle head at one end.

[0008] The buckle A is shorter than the buckle B, and the two can be interchanged.

[0009] Compared with the prior art, this utility model has significant advantages. As can be seen from the above technical solution: Clip A and Clip B are fixedly connected by several connection points. A conical nut is screwed into the screw rod, and the clip on the conical nut engages with the slot provided in Clip A. Clip A and Clip B are respectively fitted onto the screw rod and screwed with nuts. When stamping Clip A and Clip B, connection points are reserved between Clip A and Clip B. Moving the nut pushes Clip A, causing the connection points between Clip A and Clip B to disengage, resulting in misalignment of the inclined surfaces of Clip A and Clip B. Clip A and Clip B protrude at an angle, and the buckles of Clip A and Clip B are respectively engaged in the holes of lightweight bricks or hollow bricks, preventing the expansion bolts from disengaging from the holes of lightweight bricks or hollow bricks. No spring clip connection is required. This achieves the goal of reserving connection points during stamping, ensuring the clips are not reversed and will not misalign, eliminating the need for spring clip connection, making it convenient to use and low in cost.

[0018] The following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes the specific implementation methods, structure, features, and effects of this utility model.

[0019] Example 1

[0020] This utility model discloses a stamped expansion bolt for hollow bricks and lightweight bricks, comprising a sleeve A1, a sleeve B3, a clip 4, a screw 5, a conical nut 6, a nut 7, and a groove 8. The conical nut 6 is screwed into the screw 5, and the clip 4 on the conical nut 6 engages with the groove 8 on the sleeve A1. Sleeves A1 and B3 are respectively fitted onto the screw 5 and screwed into the nut 7. Sleeves A1 and B3 are fixedly connected by several connection points 2. The sleeve B3 is provided with the groove 8, and one end of sleeves A1 and B3 is respectively provided with an inclined buckle.

[0021] Example 2

[0022] This utility model discloses a stamped expansion bolt for hollow bricks and lightweight bricks, comprising a sleeve A1, a sleeve B3, a clip 4, a screw 5, a conical nut 6, a nut 7, and a groove 8. The conical nut 6 is screwed into the screw 5, and the clip 4 on the conical nut 6 engages with the groove 8 on the sleeve B3. Sleeves A1 and B3 are respectively fitted onto the screw 5 and screwed into the nut 7. Sleeves A1 and B3 are fixedly connected by several connection points 2. The sleeve B3 is provided with the groove 8, and one end of sleeves A1 and B3 is respectively provided with an inclined buckle.

[0023] When using, please refer to Figure 5 , Figure 6 When stamping sleeve A1 and sleeve B3, a connection point 2 is reserved between sleeve A1 and sleeve B3. A hole is drilled in the lightweight brick 10 or hollow brick 9, and one end of the expansion bolt is inserted. The nut 7 is moved, and the nut 7 pushes sleeve A1, causing the connection point 2 between sleeve A1 and sleeve B3 to disengage, so that the inclined surfaces of sleeve A1 and sleeve B3 are misaligned, and sleeve A1 and sleeve B3 protrude at an angle. The buckles of sleeve A1 and sleeve B3 are respectively locked in the hole of lightweight brick 10 or hollow brick 9 to prevent the expansion bolt from coming out of the hole of lightweight brick 10 or hollow brick 9.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
