Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 and figure 2 As shown, the expansion bolt with blocks of the present invention includes a bolt body 1 and an outer casing 2, the large end side of the bolt body 1 is provided with an axial slide groove 11, and the inner wall of the outer casing 2 is provided with an adapted sliding groove. block 21, so that the slider 11 snaps into the chute 21 and is slidably connected with the chute 21. Those skilled in the art should understand that, the device is provided with a chute 11 on the outer wall of the bolt body 1, and the chute should extend from the large end to the small end of the bolt body 1 and be arranged parallel to its axis. An adapted slider 21 is arranged on the inner wall of the middle part, and the slider 11 is snapped into the chute 21, so that when the nut on the bolt body 1 is screwed, since the slider 21 is always stuck in the c...

Abstract

The invention discloses an expansion bolt with a clamping block. The expansion bolt comprises a bolt body (1) and an outer sleeve (2), wherein an axial sliding groove (11) is formed in the large end side of the bolt body (1), a matched sliding block (21) is arranged on the inner side wall of the outer sleeve (2), and the sliding block (21) is clamped into the sliding groove (11) and is slidably connected with the sliding groove (11). According to the expansion bolt, the sliding groove (11) is formed in the outer wall of the bolt body (1), the matched sliding block (21) is arranged on the outersleeve (2), the sliding block (21) is clamped into the sliding groove (11), therefore, when nuts on the bolt body (1) are screwed, due to the fact that the sliding block (21) is clamped in the sliding groove (11) all the time, the mutual rotation of the bolt body (1) and the outer sleeve (2) can be effectively prevented, and the nuts can be conveniently tightened.

Description

technical field [0001] The invention relates to an expansion bolt with a clamping block, which belongs to the field of tool supplies. Background technique [0002] The tail of the bolt body in the prior art has a big head, and the bolt is covered with an outer casing slightly larger than the diameter of the bolt. There are several openings in the tail part. When the bolt is tightened, the tail of the big head is brought into the open outer casing. The outer casing is punched large so that the bolts can be fixed on the ground or the wall. However, the expansion bolt with blocks in the existing structure often causes the bolt body and the outer casing to be stuck when the hexagon nut is screwed, and will rotate so that the nut cannot be fully tightened. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide an expansion bolt with a locking block which can effectively preven...
