Description

一种易拆膨胀螺栓An easy-to-remove expansion bolt 技术领域technical field

本发明一种易拆膨胀螺栓涉及一种便于拆除拔除的膨胀螺栓，属于五金配件领域。The invention discloses an easily dismantling expansion bolt, which relates to an expansion bolt which is easy to dismantle and pull out, and belongs to the field of hardware accessories.

背景技术Background technique

现有的膨胀螺栓的螺钉、胀管是独立的，在进行拆除时，可以通过将胀管先拆除后，再将螺栓取出，形成膨胀螺栓的整体拆除，由于胀管内嵌在钻孔内，且胀管为圆管结构，内外壁光滑，无论是夹取还是其他形式的夹持，都难以形成有效的施力，缺少着力点，拆卸困难。The screws and expansion tubes of the existing expansion bolts are independent. When dismantling, the expansion tubes can be removed first, and then the bolts can be removed to form the overall removal of the expansion bolts. Since the expansion tubes are embedded in the drilled holes, In addition, the expansion tube is a round tube structure with smooth inner and outer walls. Whether it is clamping or other forms of clamping, it is difficult to form an effective force, lacking a force point, and it is difficult to disassemble.

技术解决方案technical solutions

为了改善上述情况，本发明一种易拆膨胀螺栓提供了一种能够对胀管卡夹回转，使得胀管和钻孔内壁松弛分离，易于拆卸的膨胀螺栓。In order to improve the above situation, an easy-to-remove expansion bolt of the present invention provides an expansion bolt that can rotate the expansion tube clamp, so that the expansion tube and the inner wall of the borehole are loosened and separated, and the expansion bolt is easy to disassemble.

本发明一种易拆膨胀螺栓是这样实现的：本发明一种易拆膨胀螺栓包括螺钉、胀管、螺母、垫片，胀管套置于螺钉上，且一端和螺钉上的膨胀块相抵接，垫片套置于螺钉上，螺母螺接至于螺钉上，胀管上设置有涨缝，所述胀管的口部设置有多个内弯的内豁板。An easy-to-remove expansion bolt of the present invention is realized as follows: an easy-to-remove expansion bolt of the present invention includes a screw, an expansion tube, a nut, and a gasket, the expansion tube is sleeved on the screw, and one end is in contact with the expansion block on the screw The gasket is sleeved on the screw, the nut is screwed on the screw, the expansion pipe is provided with an expansion joint, and the mouth of the expansion pipe is provided with a plurality of inwardly curved inner plates.

所述内豁板为胀管本体裁切内折形成的结构。The inner chopping plate is a structure formed by cutting the expanding tube body and folding it inward.

有益效果beneficial effect

一、能够增加胀管的施力点，便于拆卸拔除。1. It can increase the force application point of the expanding tube, which is easy to disassemble and remove.

二、 能够重复利用，节省成本。2. It can be reused to save costs.
