Abstract
The utility model relates to a hand-operated hammer anvil which is mainly composed of a drill body, a rotor sheath, an impact head, a transmission rod, a drill bit, a drill tail, etc. The utility model is characterized in that the rotor sheath is arranged in a lead body and the middle of the lead body is provided with the impact head. The two inner end surfaces of the rotor sheath and a rabbet of the impact head are provided with notches correspondingly. The utility model has the advantages that electricity is not needed, somewhat standard round holes can be struck in the surface of concrete by holding a hammer by hand. The utility model is suitable for ordinary families and building construction teams.
Description
The utility model belongs to the hand-operated tools class, is specifically related to a kind of hand knocking of getting gauge orifice in concrete building structure and bores.
At present, on the wall of xoncrete structure or ground, punch, generally use electric hammer.But under no electricity or power-off condition, electric hammer is just powerless.If, often do not show gauge orifice again with drill rod knocking punching.
The purpose of this utility model is exactly to get the problem of gauge orifice in order to solve the method for thumping by hand on the metope of xoncrete structure or ground, provides a kind of hand knocking to bore.
The utility model is realized by following technical proposals.
A hollow cylindrical rotor cover is set in drill body, the centre of cover has a front/rear end all to be the impact head of cuesta shape tenon, put at rotor, the groove that matches with the tenon shape is arranged with impacting on the tenon opposite position, rotor cover front end and drill bit can flexibly connect; Transmission rod one end with impact affixed, the other end by screw thread with bore tail and be connected, impulsive force imposes on the brill tail, affacts the impact head by transmission rod, rotor overlap and drill bit on.Realize the rotation of drill bit and mention action by spring and impact head, guarantee the standard of punching with two-sided tenon.
Be described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model schematic diagram.
The diagram mark:
1---end cap 2---rotor cover
3---drill body 4---spring
5---feather keys 6---bore tail
7---transmission rods 8---impact head
9---drill bit snap ring 10--drill bit
As shown in Figure 1.In cylindric drill body (3), a hollow cylindrical rotor cover (5) is arranged, its on two inner face all have and the corresponding groove of tenon that impacts on the head (8).The front end socket drill bit (10) of rotor cover (5), drill bit snap ring (9) restriction drill bit (10) moves vertically and deviates from.Place end cap (1) the restrict rotor cover (2) of drill body (3) front end to deviate from.Have one to impact head (8) in the centre of rotor cover (5), its two ends all have cuesta shape tenon, and are middle affixed with transmission rod (7) front end.Transmission rod (7) interlude has feather key (5), can guarantee transmission rod (7) guiding vertically along sliding in the keyway on the drill body (3), and transmission rod (7) is with spring (4) on the interlude outer end.The tail end of transmission rod (7) is connected with brill tail (6) by screw thread.
The brief description operation principle.Hand-held drill body (3) bores tail (6) with the hammer knocking.Impact force passes to by the transmission rod (7) that is connected with brill tail (6) impacts on the head (8), forces impact head (8) to clash into a rotor cover (2).Impact cuesta shape tenon bump rotor cover (2) upper groove on head (8) front end face.Groove takes the form of inclined plane on one side, impacts head (8) simultaneously because the guiding of feather key (5) can not be rotated, so in inclined-plane on the tenon and the inclined-plane contact process on the groove, force rotor cover (2) to rotate to an angle, till tenon inserts groove fully.This impulsive force with rotation is passed on the concrete surface by the drill bit (10) that is socketed in rotor cover (2) front end.After impulsive force is absorbed by concrete surface, under the effect of spring (4), impact head (8) and bounce back backward, the tenon on the end face clashes into the groove of rotor cover (2) again thereafter.With in like manner aforementioned, rotor cover (2) turns round an angle again, till tenon inserts groove fully.Meanwhile, because rotor cover (2) has certain interval in the axial direction with drill body (3), contract behind the drive rotor cover (2) when contracting behind the impact head (8), the amount of moving after drill body (3) has in the axial direction relatively is about to lift an amount on the drill bit (10).Like this, can avoid drill bit (10) to be killed by concrete.So repeatedly, promptly get out hole than standard.End cap (1) is mainly used in assembling rotor cover (2) and limits it and deviate from vertically.Drill bit snap ring (9) restriction drill bit (10) moves vertically.
The utility model is simple in structure, and is cheap, is particularly suitable for average family and uses, and it is standby also to can be used as construction team.
Claims (1)
1, a kind of hand knocking of being made up of drill body (3), drill bit (10), drill bit snap ring (9) and feather key (5) is bored, it is characterized in that: at hollow cylindrical rotor cover (2), there is a front/rear end equal in the middle of it: tap the head (8), two inner faces of rotor cover (2) with impact the groove that head (8) tenon shape matches, front end and impact head (8) affixed (5) are with spring (4) outward.
