Definitions

  • the invention relates to a screwing tool of the type mentioned in claim 1.
  • Screwing tools for multi-edged components on the circumference are already well known. These screwing tools can be Open-end wrenches, ring spanners, and the like act with which too Have the cable glands screwed into the so-called PG version, that is with armored thread. These cable bushings often come with electrical ones Control cabinets are used when it comes to internal cable connections or outside. Often, however, there is a problem that such cable bushings in cabinets sit very close together, so that relative highly trained spanners cannot be used because their Leg not in the area between adjacent cable entries let it slide in. In addition, they must be placed on the cable glands Open-end wrench removed after a short turn of the angle and set up again. This is relatively tedious.
  • Box wrenches can too the stated purpose of fastening cable bushings to the control cabinet or removing cable glands from the control cabinet should not be used, as cables are usually passed through the cable glands are passed through and thus not a ring spanner on the cable entry can be put on, that is, on the hexagon belonging to the cable duct.
  • cables are usually passed through the cable glands are passed through and thus not a ring spanner on the cable entry can be put on, that is, on the hexagon belonging to the cable duct.
  • Her essay on the Cable routing is prevented by the usual cable.
  • the invention is based, a screwing tool for the circumference to provide multi-edged components for actuation the components require little space and can also be used can come if strand-like material through the component to be screwed is passed through.
  • the screwing process should be completely executable, the screwing tool after only a short turn of the angle without it being necessary reposition on the component.
  • a screwing tool contains: a handle; a clamp, which is pivotally mounted on the handle at one end and at the other end distant from the handle is bent in a partial circle; a stop for the Clamp that is attached to the handle on the concave side of the clamp; a Reset device on the handle, which holds the clamp against the stop presses; and an actuator held by the handle with its free end the concave side of the part-circular curved end of the clamping bracket at a distance opposite.
  • a screwing tool of this type also allows the screwing to be very closely adjacent elements to be screwed to each other because of the clamping bracket very thin, in particular in its part-circular bent region can be what also applies to the actuator held by the handle. Because furthermore always a distance between the free end of the actuator and the part-circular bent end of the clamp is present, the screwing tool also easy to put on screwed elements that run along their Screw axis are penetrated by strand-like material.
  • the reset device of the clamping bracket so that the screwing tool can be operated in the manner of a ratchet in order to achieve a complete To be able to carry out the tightening process that does not require repeatedly place the screwing tools on the element to be screwed.
  • the clamping bracket in Region of its part-curved end on its concave side or On the inside circumferentially spaced driver lugs on the one for better transport of a multi-sided design Ensure component when screwing and not this task alone left to the free end of the actuator. Torques can therefore be better be transferred to the element to be screwed.
  • the driver lugs are in the circumferential direction of the part-circular curved clamping bracket starting from its free end so formed that it slowly rises at first, and towards the center of the pitch circle, and then suddenly fall off. It this results in a kind of sawtooth.
  • the steep flank of the sawtooth points from free end of the part-circular curved end of the clamping bracket away.
  • the clamping bracket and with it its bent end as well the actuator in one and the same working level. This releases the strength transfer the element to be screwed more evenly. Furthermore, can but the handle also extends in this working level, which is a very compact screwdriver leads.
  • a compression spring can preferably be used as the resetting device, which is placed between the convex side of the clamp and the handle is what leads to a relatively inexpensive construction of the screwing tool.
  • the handle can be designed in the form of a housing, around the rotatably mounted one End of the tensioning bracket, the rear end of the actuator and its displacement device, record the stop and the reset device.
  • the case-shaped handle can be divided parallel to the working level be and from a trough-shaped first and from a lid-shaped second part exist.
  • the handle can also have a chamber for receiving a second clamping bracket, the Chamber e.g. located in the trough-shaped first part.
  • the one stored here Clamping bracket can be used as a replacement for the clamping bracket already attached to the front of the handle be thought, or it can be the one stored in the housing on the supply side Clamping bracket around one with another key world area act.
  • the actuator is for adjustment the distance between its free end and the part-circular curved End of the tensioning bracket is slidably mounted, which makes it possible to do it differently to be able to screw large elements, e.g. a different Wrench size.
  • the actuator with its free end towards the free end of the clamping bracket or from this free end of the clamp is moved away.
  • a device for locking the sliding position can be on the handle the actuator are located, which facilitates its positioning and of course also its fixation in the desired position.
  • the locking device can e.g. Have projections on the actuator or are arranged on an element displacing the actuator, the Snap the projections into recesses located on the inside of the handle.
  • a locking device having a pawl
  • the pawl pivotally mounted on the handle and with her one end can be locked with the actuator.
  • the actuator can e.g. a have a suitably trained row of teeth or other structures.
  • the pawl is preferably above its other end protruding from the handle by means of spring force pivotable into the locking position. This ensures a secure locking of the actuator. It can be canceled out by the fact that this protrudes End is pivoted by hand against the spring force.
  • the handle 2 consists essentially of two parts, namely a floor pan 3 shown in FIGS. 1 and 2 and a cover, not shown, which can be placed on the floor pan 3, which can be designed as a flat plate.
  • the floor pan 3 has a floor 4 and a peripheral edge 5 which protrudes perpendicularly from the bottom 4. On the The free edge of the peripheral edge 5 then becomes the cover, not shown placed and with the help of screws, not shown, with the floor pan 3 screwed.
  • the screws are passed through openings in the cover and screwed into threaded holes 6, which are in the range of Thickenings 7 of the edge 5 are located. 1 and 2 are only two of these Threaded holes 6 and thickened areas 7 shown. They are in the back of the handle 2. Corresponding tapped holes can be in other Thickening or other approaches in the front area of the handle 2 available his.
  • the lid, not shown, and the floor pan 3 are in one working level separated from each other, which in this case is the drawing level.
  • the part of the handle 2 on the left in FIGS. 1 and 2 is intended to be its front part Area.
  • a clamp 8 corresponding in the area of the front end face 14 within the edge 5
  • An actuating section 17 of the setting slide 13 protrudes through an opening 18 in the upper region of the edge 5 and is therefore accessible from the outside.
  • This clamp 8 is made made of relatively hard or inelastic material, for example hardened Steel, and has a thickness of 1 to 2 mm and a width of about 5 mm on. It extends in the working level, which, as already explained, in the present If the drawing plane is. In its rear part on the right in Fig. 1 runs the clamping bracket 8 is relatively straight and is there at its free and to the rear Pointing end extended to a projection 19, which has a through opening is provided, through which the axis of rotation 10 projects. The axis of rotation 10 can in turn be firmly anchored to the floor 4 of the floor pan 3, with this z. B. in one piece be connected.
  • the clamping bracket 8 is then about this axis of rotation 10 swiveling. A slipping of the clamping bracket 8 from the axis of rotation 10 is thereby prevents that placed on the floor pan 3 and not shown Cover a displacement of the clamping bracket 8 in the longitudinal direction of the axis of rotation 10 prevents.
  • the axis of rotation 10 is perpendicular to the working plane.
  • the clamping bracket 8 In its left and front area in FIGS. 1 and 2, which comes out of the handle 2 protrudes, the clamping bracket 8 is bent in a part-circle. Starting from his straight course within the handle 2 is the clamp 8 after Exit from the handle 2 first angled downward and then in the present Case bent back in a semicircle.
  • This shaped Semicircle of the clamping bracket 8 serves to receive an element to be screwed, for example to accommodate a hexagon of a cable entry with PG thread.
  • driver lugs 20 protrude from the clamping bracket 8 towards the inside to the center of the part-circular curved area of the clamping bracket 8 and have a relatively flat ramp slope 21, which in the direction of the Clamping bracket 8, as seen on the axis of rotation 10, rises. After reaching one The respective driver nose 20 then quickly falls back onto the plateaus Thickness of the clamping bracket 8 from, so that each of the driver lugs 20 a kind of sawtooth forms.
  • the steep flanks of the driver lugs 20 serve for the drive of the element to be screwed, while the ramp slopes 21 the ratchet operation facilitate the screwing tool 1, as will be explained.
  • the tensioning bracket 8 runs through the front opening 15 of the handle 2 and comes to rest against a stop 9 there is designed here as a horizontal plate.
  • This horizontal plate is vertical to the bottom 4 of the floor pan 3 and can z. B. connected in one piece his.
  • the longitudinal direction of the plate 9 lies in the longitudinal direction of the handle 2.
  • the rectilinear part of the clamping bracket 8 is thus parallel to the plate-shaped Stop 9 at. This extends approximately until shortly before approach 19.
  • the clamping bracket 8 With the help of the compression spring 11, the clamping bracket 8 with its rectilinear Area pressed against the stop 9. In addition comes the compression spring 11 between the rectilinear area of the clamping bracket 8 and in the 1 and 2 lower edge 5 of the floor pan 3 to lie. Appropriate positioning means for the compression spring 11 may be present, but are here not shown for the sake of clarity.
  • the already mentioned actuator 12 and the slide valve 13 are in the range between the stop 9 and the upper edge 5 of the floor pan in FIGS. 1 and 2 3 positioned and in the present case essentially opposite to the front the axis of rotation 10 offset.
  • the actuator 12 consists of the same material as the clamping bracket 8 and also has the same thickness and width dimensions. Internally of the handle 2, the actuator 12 is substantially rectilinear and is slidably mounted on the plate-shaped stop 9. Actuator 12 and stop 9 thus run parallel to one another here. In the back the actuator 12 is angled vertically away from the stop 9 upwards and engages there from below in an actuating section 17, the part of the slide valve 13 is. This operating section 17 comes in the opening 18 in the upper edge 5 of the floor pan 3 and is therefore accessible from the outside.
  • the opening 18 is longer in the longitudinal direction of the handle 2 than the actuating section 17 in this direction, so that the operating section 17 in the Opening 18 can be moved in order to move the actuator 12 in To be able to move the longitudinal direction of the handle 2.
  • the slide valve 13 is located directly on the actuator 12 and on the side facing away from the stop 9 of the actuator 12. Actuator 12 and slide valve 13 also enforce both the through opening 16 in the front area 14 of the handle 2 and are performed there.
  • the setting slide 13 on the actuator 12th opposite side may be provided with a projection 22 which in one of several Recesses 23 can snap into place on the inside of the upper Edge 5 of the floor pan 3 are in this way to the shift position to be able to fix by actuator 12 or slide valve 13.
  • the actuator 12 In the area outside the handle 2, the actuator 12 is relative to his im Handle 2 lying horizontal area angled, namely from the clamp 8 way. The actuator 12 initially runs in this angled region also straight and is then in its free end again to the clamp 8 bent. The free end of the actuator 12 comes approximately at one Circumferential position of a circle, which can be obtained by adding the Clamping bracket 8 formed circle would get a full circle. With others Words corresponds to the position of the free end of the actuator 12 approximately a circumferential position one of the driver lugs 20. Alternatively, the actuator 12 outside of the handle 2 but also parallel to its inside the handle 2 lying, straight area extend to the outside free end to be angled towards the clamping bracket 8.
  • the screwing tool 1 If with the screwing tool 1 a z. B. hexagon, about one Cap of a PG cable entry, the screwing tool 1 with its Partially circular clamping bracket 8 in the axial direction towards screwed part attached. If the part to be screwed is strand-shaped It could be well established that runs in its axial direction strand-like material beforehand through the gap between the free end of the clamping bracket 8 and the free end of the actuator 12 pass through. Should that be too screwing component in its outer diameter not the inner diameter of the part-circular bent region of the clamping bracket 8, so can the actuator 12 by moving the slide valve 13 to the screwing component are brought up so that it is as close to this comes to lie.
  • the clamp 8 must either with its one or be placed axially on the component with its other side.
  • FIGS. 4 and 5 show a second embodiment of the invention Screwing tool 1.
  • the same parts as in FIGS. 1 and 2 are with are provided with the same reference numerals and are not described again.
  • screwing is how the second works Embodiment identical to that of the first embodiment, so that this will not be discussed again.
  • the screwing tool according to the second embodiment differs differ from that of the first embodiment first characterized in that within the bottom wall 3 in the rear area of the Handle 2, a chamber 24 for receiving another clamp 8a is formed.
  • a chamber 24 for receiving another clamp 8a is formed within this chamber 24, one with the Handle 2 are fixed axle extension 25 on which an extension 19a of the further clamping bracket 8a can be placed, which is a for this purpose has a suitable through opening.
  • the chamber 24 can also be provided with chamber webs 26, the position of which is selected such that the further clamping bracket 8a stored in the handle 2 as little as possible can move.
  • This further clamping bracket 8a is about to replace the Clamping bracket 8 thought, so has the same wrench size range as this on, or can be thought of as a supplement to this, if one different wrench size range than the clamping bracket 8.
  • the screwing tool according to FIGS. 3 and 4 has one Locking device 28 with a pawl 29.
  • This pawl 29 is designed like a lever and has a first end or a first leg 30 and one in the opposite direction extending second end or second leg 31. Is in the middle the pawl 29 is pivotable about a pivot axis 32 which on Handle 2 is mounted, in the area of the opening 18.
