Described two steel balls lay respectively in described two key through holes;
Described protheca, stage clip, interstage sleeve, gland socket successively, spacing on the lateral wall of described body, and try hard to recommend the annular groove or the pit that under the moving described gland described steel ball is retracted into outside being provided with on the madial wall of described interstage sleeve.
One end of described body lateral wall is provided for the step of spacing described protheca, and the other end is provided with the check ring that is used for spacing described gland, and described check ring is positioned in the annular groove of offering on the described body lateral wall.
Be threaded by connecing spiral shell between described extension bar and the body.
Convex with the bulge loop that is used to fasten described stage clip on the lateral wall of described interstage sleeve, an end of described gland coats the bulge loop of described interstage sleeve, and the other end that described gland does not coat described interstage sleeve is provided with the deep-slotted chip breaker of being convenient to described check ring setting.
Be arranged with the groove of being convenient to described stage clip holding before described.
Described interstage sleeve and described gland are formed in one.
Beneficial effect after the employing technique scheme is: a kind of dop converter that is used for electric hammer of the present utility model can realize holding with the electric hammers with four hole dops the function of five hole drill hammers, the described dop converter that is used for electric hammer can independently separate with electric hammer, and connect the precision height, can realize with the electric hammer rapid abutting joint or separate.
Description of drawings
Fig. 1 is for being used for the cross-sectional schematic of the dop converter of electric hammer in the utility model;
Fig. 2 is the cross-sectional schematic of body in the utility model;
Fig. 3 is the cross-sectional schematic of gland in the utility model;
Fig. 4 is used for the cross-sectional schematic of the dop converter of electric hammer for the utility model, and this there is shown steel ball and breaks away from the structure that limits the position.
The specific embodiment
The specific embodiment of the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the dop converter that is used for electric hammer in the utility model includes extension bar 1, body 2, connects spiral shell 3, interstage sleeve 4, stage clip 5, gland 6, protheca 7, two steel balls 8 and check rings 9, wherein:
It is cylindric that extension bar 1 roughly is, and the one end is identical with the structure that four hole drill hammers are connected with electric hammer, is convenient to be connected with electric hammer, and the other end is provided with and connects the external screw thread that spiral shell 3 is threaded.
Connect spiral shell 3, be used to connect extension bar 1 and body 2, outer surface is equipped with screw thread within it, can certainly be undertaken by other structures fixedly connected, as long as extension bar 1 and body 2 removably are fixed together.
Two steel balls 8 lay respectively in two key through holes 17 of body.
Protheca 7, stage clip 5, interstage sleeve 4 and gland 6 are enclosed within the outside of body 2 successively, wherein stage clip 5 between protheca 7 and interstage sleeve 4, step 11 butts on protheca 7 and body 2 lateral walls, protheca 7 is provided with the groove 19 that is used for clamping stage clip 5 simultaneously.
Annular groove that is provided with on the internal face of interstage sleeve 4 or pit 10, outer side surface are provided with the bulge loop 15 that is used for butt stage clip 5.
One end of gland 6 is formed with step 18 on the sidewall within it, utilizes this step 18 and interstage sleeve 4 sockets, and coats the bulge loop 15 of interstage sleeve 4 lateral walls, prevents to break away from when stage clip 5 power effect outside is excessive the qualification of interstage sleeve 4.The other end of gland 6 is provided with and is convenient to the deep-slotted chip breaker 14 that described check ring is provided with simultaneously.Wherein gland 6 can be integrally formed with interstage sleeve 4, reduces the use and the processing of parts.
The operation principle of dop converter of the present utility model is as follows:
At first an end of extension bar 1 is connected with electric hammer, the other end is connected and fixed by an end that connects spiral shell 3 and body 2, and the other end of body 2 can be connected with five hole drill hammers, thereby can make existing electric hammer also can be extensive use of five holes and impact dop, make the scope of application of five hole drill hammers wider, and simple and reliable for structure.An end that only needs in use five hole drill hammers directly to be inserted body gets final product, utilize the keyway in the protruding key 12 5 hole drill hammers to connect, and transmission button square, utilize simultaneously two steel balls 8 enter five the hole drill hammers groove and locate, when drill hammer is cheated in needs taking-up five, as long as promote gland 6, interstage sleeve 4 is slided on body 2 lateral walls in the lump, as shown in Figure 4, annular groove or pit 10 up to interstage sleeve 4 are corresponding with steel ball 8, cancel compressing of 4 pairs of steel balls 8 of interstage sleeve, and then steel ball 8 parts are retracted into the annular groove or the pit 10 of interstage sleeve 4, thereby it is spacing to release 8 pairs five holes of steel ball drill hammer, takes out five hole drill hammers.
