Abstract
The utility model relates to an expansion bolt which comprises a bolt body, an expansion pipe, a flat washer, a spring washer and a nut. The nut, the expansion pipe, the flat washer and the spring washer are all sleeved on the bolt body. The flat washer and the spring washer are placed between the expansion pipe and the nut. A conical platform is arranged at one end of the bolt body, the end with the larger diameter of the conical platform is placed on the outer side, an opening groove is formed in one end of the outer side of the expansion pipe, reinforcing ribs are arranged on the end face, placed on one side of the spring washer, of the flat washer, and the reinforcing ribs are evenly distributed in the axial direction of the flat washer. According to the technical scheme, the expansion bolt can well prevent the flat washer from being deformed and can be dismantled conveniently after being used for a long time.
Description
Technical field
The utility model relates to fastener areas, particularly a kind of EXPANSION ANCHOR BOLTS.
Background technique
Existing a kind of EXPANSION ANCHOR BOLTS, include bolt body, expansion tube, plain washer, spring washer and nut, described nut, expansion tube, plain washer, spring washer all are set on the bolt body, plain washer, spring washer are between expansion tube and nut, bolt body one end is provided with the taper platform, and the bigger end of taper platform diameter is positioned at the outside, and the expansion tube outside one end is provided with opening slot.
But, this expansion of structure bolt, when locking, described plain washer is easy to generate distortion owing to be subjected to the nut extruding, after compressing for a long time, because plain washer has produced distortion, thereby makes it when dismounting, and is very inconvenient.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of EXPANSION ANCHOR BOLTS, and it can prevent well that plain washer from producing distortion, still can be for convenience detach after long-time the use.
The technical solution of the utility model: a kind of EXPANSION ANCHOR BOLTS, include bolt body, expansion tube, plain washer, spring washer and nut, described nut, expansion tube, plain washer, spring washer all is set on the bolt body, plain washer, spring washer is between expansion tube and nut, bolt body one end is provided with the taper platform, the bigger end of taper platform diameter is positioned at the outside, the expansion tube outside one end is provided with opening slot, it is characterized in that: the end face that described plain washer is positioned at spring washer one side is provided with stiffening rib, and described stiffening rib axially evenly distributes around plain washer.
Adopt technique scheme, by the stiffening rib that the end face that is positioned at spring washer one side at plain washer arranges, can prevent well that plain washer from producing distortion, still can make things convenient for Bolt dismantling after long-time the use; And this stiffening rib can also prevent that the spring packing ring skids, thereby makes that bolt locking is more firm.
Further setting of the present utility model: described expansion tube is provided with the buffering groove between the end face of taper platform one side and madial wall.
Adopt above-mentioned further setting, the buffering groove of setting can reduce expansion tube when expanding, the collision between expansion tube and the taper platform, thus can protect taper platform, expansion tube.
Further setting more of the present utility model: the sidewall that described expansion tube is positioned at open slot position is provided with some annular anti-slip tanks, and the spacing of described adjacent two anti-slip tanks equates.
Adopt above-mentionedly further to arrange, the anti-slip tank of setting can be so that expansion tube can not skid after installation, thereby makes the EXPANSION ANCHOR BOLTS positioning stablity again.

Embodiment
As Fig. 1, shown in 2, a kind of EXPANSION ANCHOR BOLTS, include bolt body 1, expansion tube 2, plain washer 3, spring washer 4 and nut 5, described nut 5, expansion tube 2, plain washer 3, spring washer 4 all is set on the bolt body 1, plain washer 3, spring washer 4 is between expansion tube 2 and nut 5, bolt body 1 one ends are provided with taper platform 6, the bigger end of taper platform 6 diameters is positioned at the outside, expansion tube 2 outsides one end is provided with opening slot 21, the end face that described plain washer 3 is positioned at spring washer 4 one sides is provided with stiffening rib 31, and described stiffening rib 31 axially evenly distributes stiffening rib 31 rectangular shapes around plain washer 3.By the stiffening rib 31 that the end face that is positioned at spring washer 4 one sides at plain washer 3 arranges, can prevent well that plain washer 3 from producing distortion, still can make things convenient for Bolt dismantling after long-time the use; And this stiffening rib 31 can also prevent that spring packing ring 4 skids, thereby makes that bolt locking is more firm.
As shown in Figure 3, in the utility model specific embodiment, described expansion tube 2 is provided with buffering groove 22 between the end face of taper platform 6 one sides and madial wall.The buffering groove 22 that arranges can reduce expansion tube 2 when expanding, the collision between expansion tube 2 and the taper platform 6, thus can protect taper platform 6, expansion tube 2.
Shown in Fig. 1,3, in the utility model specific embodiment, the sidewall that described expansion tube 2 is positioned at opening slot 21 positions is provided with some annular anti-slip tanks 23, and the spacing of described adjacent two anti-slip tanks 23 equates.The anti-slip tank 23 that arranges can be so that expansion tube 2 can not skid after installation, thereby makes the EXPANSION ANCHOR BOLTS positioning stablity.
