Abstract
The utility model relates to an expansion bolt belonging to the technical field of fixing fasteners. An inner hole of a connection screw nut (3) of the utility model is a stepped hole whose large hole is inside provided with an expansion core (2) and small hole is a screw-thread hole whose screw-threads have the size matched with the size of the screw-threads of a connection screw rod (4). An expansion sleeve (1) is tightly fastened outside the connection screw nut (3). Being time and labor saving, the utility model has the advantages of simple structure, convenient dismounting and low cost and is suitable for mounting of any wall, and the connection screw rod (4) can be selected according to the size of the mounted object.
Description
The utility model is a kind of EXPANSION ANCHOR BOLTS, belongs to install to use technical field of fastening.
People install object now, use the plastic expansion nail usually, and plastic expansion is followed closely when fixed object, by manpower precession wood screw plastic cap are expanded and reach the purpose that tightens up object, and effort and screw easily skid and can not bear a heavy burden during use, and object dismounting inconvenience is installed.95241525.9 patent, because Component are more, the processing cost height when especially on softer body of wall object being installed, does not have enough power that expansion sleeve is expanded, so do not implement.
The purpose of this utility model provides a kind of simple in structure, and processing cost is low, and the labour-saving EXPANSION ANCHOR BOLTS is installed.
The purpose of this utility model is achieved in that this bolt comprises the attaching nut, connecting screw rod, expansion sleeve, expanded core, attaching nut's endoporus is step-like, expanded core is housed in the macropore, and aperture is tapped hole and connecting screw rod coupling, and the attaching nut is with expansion sleeve outward.
Expansion sleeve can be made with plastics, and front end face has a hole, vertically opens a bite to the stage casing, and anterior outer wall is a screw thread, and the rear portion is fastened on attaching nut's outer wall.
The attaching nut makes with hexagonal steel, is processed with boss on the outer wall, is convenient to expansion sleeve and tightens up.
Expanded core is a Cylinder, and an end falls garden or chamfering.
The utility model compared with prior art has following advantage:
1, is applicable to the installation of any body of wall, can selects screw rod, save time, laborsaving, convenient disassembly according to the size that object is installed.
2, simple in structure, processing cost is low.
Drawing of the present utility model is described as follows
Fig. 1 is the structural representation of the utility model EXPANSION ANCHOR BOLTS.
Fig. 2 is the left view of Fig. 1.
Below in conjunction with accompanying drawing the utility model embodiment is described further: this EXPANSION ANCHOR BOLTS is made up of expansion sleeve (1), expanded core (2), attaching nut (3), connecting screw rod (4).Attaching nut (3) is made by hexagonal steel, and the two ends of outer wall are boss, so that do not relatively rotate when being connected with expansion sleeve, endoporus is a step hole, expanded core (2) is housed in the macropore, aperture is a tapped hole, mates with connecting screw rod (4) thread size; Connecting screw rod (4) can be selected standard piece for use.Expansion sleeve (1) is plastics, and front end face has a hole, and longitudinal opening is pressed with screw thread to the stage casing on the anterior outer wall, increases frictional force, and the rear portion is fastened on outside the attaching nut (3).
When this EXPANSION ANCHOR BOLTS is used, put it in the hole of preboring, connecting screw rod (4) is exposed, to inward turning connecting screw rod (4), expanded core (2) is entered in the expansion sleeve (1), expansion sleeve (1) distending, reach the purpose that tightens up, select connecting screw rod (4) according to the installation object then.
