Abstract
The utility model provides an earth clamp that ground connection is firm, adapted simultaneous various environment operations. A type of screwing ground clamp, is the connecting device who is used for earth connection and ground connection stake, including the splint pivot of punch holder, lower plate and connection punch holder and lower plate afterbody, the welding of lower plate tail end has the earth connection connecting plate, goes up the lower plate outside and has welded device for tighten. The utility model discloses the appearance is triangle -shaped, can be applicable to various operational environment, utilizes and to screw sleeve and pressurization contact to the pressurization fastening of work portion, and fastening pressure is big, makes earth connection and ground connection stake fixed firm, and it is quick to screw, hard, and fixed process quick and save time.
Description
Technical field
The utility model relates to a kind of power equipment Work tool, is specifically related to a kind of earthing clamp.
Background technology
Present earthing clamp is generally divided into two kinds, a kind of clamp type as shown in Figure 1, a kind of push rod type as shown in Figure 2.Clamp type utilizes spring pressure to step up earth connection, is suitable for various operating environment, if but spring pressure cross conference and greatly consume manpower, if spring pressure is too small, easily come off, ground connection is insecure; Push rod type ground connection is firm, but it is long to screw push rod required time, and due to push rod type earthing clamp profile now used Founder, runs into operation that is narrow or angle then very difficult, even can not operate.
Utility model content
In order to overcome the above problems, the utility model provides that a kind of ground connection is firm, the earthing clamp of the various environment work of simultaneous adaptation.
Concrete scheme of the present utility model is: one screws type ground clamp, it is the jockey for earth connection and ground stud, comprise train wheel bridge, lower plate and connect the clamping plate rotating shaft of train wheel bridge and lower plate afterbody, lower plate tail end is welded with earth connection connecting plate, and upper lower plate outside is welded with winding device.
Described winding device comprises the propelling sleeve of screw shell and its next-door neighbour; Screw shell is welded on upper lower plate by inner sleeve, and inner sleeve outer wall is distributed with screw thread, outer sleeve inner wall has the screw thread corresponding with the screw thread on inner sleeve outer wall.
The outer tube sleeve of propelling sleeve and screw shell is one.
Winding device comprises the pressurization contact matched with propelling sleeve on train wheel bridge outer wall.
Pressurization contact is trapezoidal, triangle, arc or irregular shape.
Train wheel bridge head is welded with operate portions upper plate, operate portions upper plate inwall offers vee gutter or half elliptic groove, lower plate head is welded with the operate portions lower plate corresponding to operate portions upper plate, and operate portions lower plate offers the vee gutter corresponding to operate portions upper plate or half elliptic groove.
Ground wire connecting plate offers screwed hole, and screwed hole and earth connection are bolted.
The beneficial effects of the utility model, the utility model profile is triangle, goes for various operational environment, and utilization screws sleeve and pressurization contact is fastening to operate portions pressurization, and fastening pressure is large, makes earth connection and ground stud fixation; And screwing fast, leicht fallen D/A, fixation procedure saves time fast.

Fig. 1 is clamp type earthing clamp structural representation.
Fig. 2 is push rod type earthing clamp structural representation.
Fig. 3 is the utility model structure chart.
Embodiment
As shown in Figure 3, a kind of type earthing clamp that screws comprises train wheel bridge 1, lower plate 2 and connects the clamping plate rotating shaft 3 of train wheel bridge and lower plate afterbody.Lower plate tail end is welded with earth connection connecting plate 4, earth connection connecting plate 4 offers screwed hole 5, is connected by respective bolt with earth connection.Be welded with pressurization contact 6 in the middle part of train wheel bridge, pressurization contact 6 is set to trapezoidal, triangle, arc or irregular shape.Train wheel bridge 1 head is welded with operate portions upper plate 12, operate portions upper plate 12 inwall offers vee gutter or half elliptic groove, lower plate 2 head is welded with the operate portions lower plate 13 corresponding to operate portions upper plate 12, and operate portions lower plate 13 offers the vee gutter corresponding to operate portions upper plate 12 or half elliptic groove.Train wheel bridge 1 and lower plate 2 outer wall afterbody are welded with winding device 7, winding device comprises screw shell 8, propelling sleeve 11 and pressurization contact 6, it is outside with lower plate 2 that screw shell 8 is welded on train wheel bridge 1 by inner sleeve 9, inner sleeve 9 outer wall is distributed with screw thread, outer tube 10 inwall has the screw thread corresponding with the screw thread on inner sleeve 9 outer wall.Be provided with propelling sleeve 11 before screw shell 8, propelling sleeve 11 and outer tube 10 inwall are one.
The outer tube 10 of twisting screw shell 8, outer tube 10 is separated with inner sleeve 9, the propelling sleeve 11 that then outer tube 10 front end connects moves with the movement of outer tube 10, the propelling sleeve 11 of movement can press pressurization contact 6 and apply pressure to pressurization contact 6, because propelling sleeve 11 inner space is certain, pressurization contact 6 drives train wheel bridge to press to lower plate, thus makes the ground stud in the middle of operate portions and operate portions fastening.
