Definitions

  • the invention is based on a hand tool according to the preamble of claim 1 (see, for example US-A-5,466,183 ).
  • the hand tool according to claim 1 has the advantage that a housing shell has an inspection cover, which is easy to open and with which - without having to open the housing completely - the power line or the cable grommet is easily and quickly replaceable.
  • Figure 1 is a perspective view of a hammer drill according to the invention with depth stop
  • Figure 2 is an exploded view of the housing of the hammer drill
  • Figure 3 is a partial bottom view of the hammer drill with open inspection cover
  • FIG. 4 shows the view according to FIG. 3 with the inspection cover closed.
  • FIG. 1 shows a three-dimensional view of a hand-held power tool 10 designed as a hammer drill in the front left view.
  • the hand tool has a housing 12, which consists of a left and right longitudinally split housing shell 121, 122 with a designed as a spade handle handle 14, which includes a switch button 16 from the down an e-cable 18 for the power supply of the not shown, inside a to Housing 12 belonging engine housing 20 arranged engine exits.
  • the motor housing 20 is integrally divided with the housing shells 121, 122 in the motor housing shells 201, 202, which are arranged at right angles to a longitudinal axis 27 of the power tool 10 angled.
  • the longitudinal axis 27 is defined by a machine neck 22, a chuck 24 and an insert tool 26 designed as a drill.
  • an additional handle 28 steps away from the longitudinal axis 27, which is detachably supported on the machine neck 22 by means of a clamping band 30.
  • the auxiliary handle 28 includes an upper extension 29 with a concave, which is intended to bear against the machine neck 22 and the auxiliary handle 29 gives a secure grip on the housing 12.
  • a depth stop 32 embodied as a hexagonal rod is mounted longitudinally displaceably in a rotationally secured manner in a longitudinal guide 38 designed as a hexagonal bore.
  • the depth stop 32 has on opposite hexagonal surfaces an upper and a lower tooth profile 34, 35 with which it is releasably retained in the longitudinal guide 38 in a form-fitting manner.
  • FIG. 2 shows an exploded view of the housing of the power tool 10. It is clear that the housing 12 consists of two longitudinally split housing shells 121, 122. These are held together by means of a snap ring 123 in the front region of the machine neck. At the bottom of the motor housing 20 sits a hinged lid 60 which closes this frontally. This hinged lid 60 is articulated in the left housing shell 121 in the screw 64 and covers the lower half of the motor housing 20 in the carbon brushes. About a locking screw 66 of the hinged lid 60 is attached to the motor housing 20 for proper use. The locking screw 66 is captively connected to the hinged lid 1.
  • the connection between the motor housing 20 and hinged lid 60 is released.
  • the hinged lid can be folded away without having to be completely removed from the device.
  • the locking screw 66 can be released with a screwdriver or with a key or a coin.
  • the folding away of the hinged lid 60 allows easy and comfortable brush replacement.
  • the motor housing 20 engages around a separate envelope housing (FIG. 6), which is inserted between the housing shells 121, 122 during assembly.
  • This envelope housing 62 carries at the lower end a radially outwardly facing threaded bore 68 for engagement of the locking screw 66 and also the Kohlbürsten for the engine.
  • the right housing shell 122 is designed in two parts. It carries a small cover for inspection of the power line 18.
  • the lid is attached to the housing 12 with two screws. After removing the lid, the power cord 18 and the cable grommet 19 can be easily replaced or replaced.
