AI Technical Summary
Existing expansion bolts are easy to loosen and detach from the wall during use, and have poor stability.
A movable expansion bolt is designed, which uses a fixed installation clip on a conical nut, a reverse buckle sleeve, a two-way buckle sleeve and a forward buckle sleeve on the screw, and a retaining spring is installed on each buckle sleeve. It is inserted into the hole through the staggered inclined surface to achieve multiple reverse buckles and enhance stability.
It effectively prevents the expansion bolts from detaching from the wall holes, improves stability, ensures that they are not easy to loosen, and provides higher safety.

[0016] The following in conjunction with the preferred embodiments of the utility model, the specific implementation of the utility model, structure, features and its efficacy, are described as follows.
[0017] The utility model discloses a movable expansion bolt, compared with prior art, has obvious beneficial effect, from above technical scheme can know: through the fixing installation of the card in the taper nut, the taper nut is screwed into the screw rod, the upper end of the screw rod is sleeved with the reverse buckle sleeve, the middle part is sleeved with the two -way buckle sleeve, the lower end is sleeved with the clockwise buckle sleeve and is screwed into the nut, the card in the card groove set up on the reverse buckle sleeve is inserted into the card fixedly installed on the taper nut.
[0018] When using, referring to Figure 3, move the nut 7, the nut 7 pushes the clockwise sleeve 1, the clockwise sleeve 1 is dislocated with the inclined surface of the bidirectional sleeve 3, the bidirectional sleeve 3 is dislocated with the inclined surface of the anticlockwise sleeve 4, the two clamping springs 2 are respectively opened, the bidirectional sleeve 3, the clockwise sleeve 1 and the anticlockwise sleeve 4 are inclined and protrude, the heads of the bidirectional sleeve 3, the clockwise sleeve 1 and the anticlockwise sleeve 4 are respectively clamped in the holes, preventing the expansion bolts from being separated from the holes of the wall body, according to the actual situation, a plurality of bidirectional sleeves 3 can be installed to realize a plurality of anticlock, which is not easy to loosen and will not be separated from the wall body, safe and stable.
[0019] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the scope of the technical scheme of the present application.
