Abstract
Description
Technical field
The present invention relates to Hardware fitting field, and in particular to a kind of expansion bolt of Fast Installation.
Background technology
The turn of the screw on brick wall or cement wall makes a call to a sizeable hole on the wall, it is necessary to which electricity consumption is bored, then bolt Insert, nut is tightened.Therefore in actual mechanical process, through be commonly encountered beat hole and inappropriate situation, it is necessary to repeatedly Drill or need thing pad to live bolt, it is cumbersome, lose time, and sometimes can use the longevity there are bolt strength deficiency Order low situation.In order to ensure use intensity, currently used more is expansion bolt, and the expansion bolt used at present is general Including screw rod, nut and expansion sleeve, in use, by screwing in screw rod by expansion sleeve front end distending, make bolt card in the hole of wall In.Although expansion bolt can guarantee that subsequent use intensity, still need first to punch, rear insertion, existing expansion bolt Expansion sleeve aperture is fixed, and after screw head enters expansion sleeve inside, the degree that expansion sleeve expands outwardly can be less and less, If the aperture of wall is larger, will or bolt falling not tight there is a situation where card, be commonly encountered in practical operation such existing As.
The content of the invention
The present invention installs simple, quickly expansion in view of the above problems, providing one kind while use intensity is ensured Bolt.
The technical scheme is that：Including expansion bolt body and mounting head, the expansion bolt body includes expansion The screw rod and nut being sequentially arranged at from top to bottom on dilating screw, gasket and expansion cylinder, the bottom of the dilating screw are equipped with The drill of sheet, on the dilating screw, the top of nut be equipped with some protrusions；
The lower end of the expansion cylinder is equipped with some openings one；
The mounting head includes the upper mounting head that can be fixedly connected with drill bit, and lower mounting head, the lower mounting head are Hollow structure, the inner wall of the hollow structure are equipped with some open recess being adapted to the protrusion.
On the expansion cylinder, opening one top be equipped with it is spiral helicine opening two.
The dilating screw is equipped with spiral groove.
The drill is integrally formed with dilating screw.
The drill bottom is wedge angle.
The top length of the drill is equal to the diameter of dilating screw bottom.
The side wall of the lower mounting head is double-decker, and the open recess is set extruded on internal layer；
Cylinder is equipped between internal layer and outer layer.
Controller is further included, the motor and cylinder of the electric drill are connected with controller respectively.
The beneficial effects of the invention are as follows：Before installation, the upper end of upper mounting head can be fixed on to the head of electric drill, then It is hand steered to fix by the raised alignment open recess on expansion bolt body, drill alignment is needed to the place of installation bolt, is opened Dynamic electric drill is simultaneously pressed downward, and drill can smoothly pierce the place of installation bolt, after piercing, by electric drill reverse starting, drives expanding screw Bar is upward, until locked.The present invention need not punch in advance, directly pierced with the drill of expansion bolt in itself, can guarantee that drilling Size is suitable, and reduces operating procedure, the installation of bolt is become simple, while locked expansion bolt also ensure that subsequently Use intensity.

Embodiment
The present invention is illustrated below in conjunction with the accompanying drawings.
It is subject in Fig. 1 in orientation in the present invention.
The present invention includes expansion bolt body and mounting head, and as shown in Figs. 1-2, the expansion bolt body includes expanding screw The bar 1 and nut 2 being sequentially arranged at from top to bottom on dilating screw 1, gasket 3 and expansion cylinder 4, the bottom of the dilating screw 1 Drill 5 equipped with sheet, the present invention, without punching in advance, can ensure the size in hole by being squeezed between drill 5 in wall While suitable, reduce installation procedure, on the dilating screw 1, the top of nut 2 be equipped with some raised 6, described raised 6 It is fixed on dilating screw 1, quantity preferably 2, during installation, clamps protrusion 6 with instrument, forward direction turns punching, reversely turns It is locked；
The lower end of the expansion cylinder 4 is equipped with some openings 1, and enough spaces are reserved to expansion.
As in Figure 3-5, the mounting head includes the upper mounting head 7 that can be fixedly connected with drill bit, and lower installation First 8, the lower mounting head 8 is hollow structure, and the inner wall of the hollow structure is equipped with some with raised 6 opening being adapted to Groove 81.
On the expansion cylinder 4, opening 1 top be equipped with it is spiral helicine opening 2 42, enable punching produce break flour Smoothly discharge.
The dilating screw 1 is equipped with spiral groove, the break flour that convenient discharge punching produces.
The drill 5 is integrally formed with dilating screw 1, is ensured that drill intensity is enough, is hardly damaged.
5 bottom of drill is wedge angle, guarantees smoothly to punch.
The top length of the drill 5 is equal to the diameter of dilating screw bottom, ensures that punching aperture is suitable.
The side wall of the lower mounting head 8 is double-decker, and the open recess 81 is set extruded on internal layer；
Cylinder 82 is equipped between internal layer and outer layer.
Controller is further included, the motor and cylinder of the electric drill are connected with controller respectively.
The present invention application method be：The drill bit of electric drill is removed, the drill bit that upper mounting head 7 is fixed on to electric drill is original Place, is then directed at open recess 81 by the protrusion 6 on dilating screw and is put into lower mounting head 8, hand steered to fix, and then will bore 5 perpendicular alignmnet of knife needs the place of installation bolt, and starting electric drill makes electric drill rotate forward and be pressed downward, and drill 5 can smoothly pierce installation The place of bolt, after piercing, by electric drill reverse starting, drives dilating screw 1 upward, controller receives electric drill reverse signal Afterwards, start cylinder, it is pushed in dilating screw uphill process, push down nut, make nut also in original position, until Expansion bolt locks, and so far, a bolt installation terminates.The present invention need not punch in advance, directly with expansion bolt in itself Drill pierces, and can guarantee that drilling size is suitable, and reduces operating procedure, the installation of bolt is become simple, while locked Expansion bolt also ensure that subsequent use intensity.The mounting head of adaptation is equipped with, installation is fast and effective.
