Description

  The present invention relates to an impact tool used for the purpose of physically applying an impact corresponding to a tip shape of an impact acting piece to an impacted body.

  A striking material is movably assembled to the main body so as to pass through the main body, and an impacting piece with which the striking material abuts is provided at the tip of the main body, and the striking material is moved along the main body. There is a structure in which the impact acting piece is brought into contact with the impact acting piece so that an action according to the tip shape of the impact acting piece is given to the impacted body (for example, Patent Document 1).

Utility Model Registration No.3051699

  The conventional structure adopts a structure in which the striking material that is a block body moves along the main rod that is supported by the hand with the striking material exposed to the outside, so that the pressure receiving material by the striking material, that is, during impact work on the impacted body There is a risk of striking the striking material against the surroundings without securing sufficient space (due to an error in the measurement), and above all, a movement operation along the main body of the striking material using the hand is necessary, so the work space is reduced. I need.

  The present invention has been created with the object of providing an impact tool that is easy to use, paying attention to such drawbacks of the prior art.

  A cylindrical main body having a hitting surface on the inner wall of the inner cavity and a fitting body having a front end surface that hits and separates the hitting surface from each other inside and outside. The weight member is detachably attached to one end of the hitting surface side and the rear end corresponding to the front end surface of the fitting insertion rod, and the impact action piece is detachably attached to the other.

  According to the present invention, the weight member is attached to one of the cylindrical main body and the fitting insertion rod inserted into the cylindrical main body, the impact action piece is attached to the other, the impact action piece is applied to the impacted body, and the weight material is faced. Can impact each other on the impacted body by the impacting piece.

  Moreover, since the impact work can be performed only by supporting the cylindrical main body or the insertion rod on the side to be moved, a work space is not required, and the longitudinal direction can be selected by selecting the attachment side of the weight material etc. This tool can be used as an impact tool with any direction, and can provide a tool with a novel structure that has never been seen before.

  The drawings show an embodiment of an impact tool according to the present invention, FIG. 1 is a partially cutaway front view, and FIG. 2 is a front view of each attachment material.

  In the figure, reference numeral 1 denotes a steel cylindrical main body. The cylindrical main body 1 is provided with a thick portion 2 on one end side in the longitudinal direction, and the lumen portion 3 corresponds to a short portion on the one end side and the one end side. An end portion is divided into long portions, and the short portion of the opening on one end side of the cylindrical main body 1 is formed as an assembling portion 5 for detachably attaching the impact action piece 4 for the weight material. The long portion of the opening at the other end of 1 is an insertion portion 7 of the insertion rod 6 that is assembled by inserting the insertion rod 6 from the opening end.

  The assembly part 5 provided on one end side of the cylindrical main body 1 is connected to the axis of the assembly part 5 (lumen part 3) at the center on the back wall (the thick part 2) side constituting the assembly part 5. A regulating rod 8 is installed at an orthogonal position and engaged with a groove 27 provided in the impact acting piece 4 to restrict the rotation of the acting piece 4 and the base end is screwed to the cylindrical main body 1. It comprises a leaf spring 10 which is fastened with a combined screw 9 and introduced and arranged on the inside, and comprises a cylindrical mounting rod 4b having the groove 27 at its free end and a semi-cylindrical working piece 4a. The mounting rod 4b of the impact acting piece 4 is inserted and assembled, and the assembled state is maintained by locking the bent portion 10a of the leaf spring 10 to the recessed notch 12 provided on the peripheral side of the mounting rod 4b. It is like that.

  The impact acting piece 4 is used, for example, when attaching / detaching the attachment pin (slide pin) P of the attachment of the heavy machine shown by a two-dot chain line in FIG. 1, but in FIG. The impact acting piece 14 attached to the side of the fitting insertion rod 6 is used to function.

  The fitting insertion portion 7 having the other end side of the cylindrical main body 1 as an open end has a back wall formed by the thick portion 2 as a hitting surface 16, and a tip surface 6 a ′ of the fitting insertion rod 6 is opposed to this. The cylindrical main body 17a of the retaining member 17 is fixed to the opening end, and the fitting insertion rod 6 is fitted to the fitting insertion portion 7 through the cylindrical main body 17a. Inserted and assembled.

  The insertion rod 6 is made of a steel round bar, and has a striking portion 6a which has a slightly small diameter at the tip and abuts against (relatively) the striking surface 16 and is an intermediate portion on the striking portion 6a side. The retaining ring 18 is wound around the inner edge of the main body 17a of the retaining member 17 to prevent the retaining member 17 from being detached from the main cylinder 1 and corresponding to one end on the striking portion 6a side. A threaded portion 19 is protruded from one end of the head, and attachments such as weight members 20, 21 and impact acting pieces 14, 22, 23 are attached thereto.

  As shown in FIG. 1, the impact acting piece 4 is applied as a weight member, and the impact acting piece 14 is attached using the threaded portion 19 at the end of the insertion rod 6 to be applied as an impact tool. The main cylinder 1 is moved backward while guiding the action piece 14 of the impact action piece 14 against the impacted body d such as a rock or a concrete wall, and then guided to the fit insertion rod 6. When the guide body is suddenly advanced to the original position while being guided, the impact acting piece 4 assembled to the cylindrical main body 1 becomes a weight, and its weight is loaded on the moving cylindrical main body 1 so that the cylindrical main body 1 side is covered. The striking surface 16 acts as a striking surface and comes into contact with the tip surface 6a 'on the side of the fitting insertion rod 6, and the action piece 14a of the impact working piece 14 attached to the fitting insertion rod 6 pressed on the tip surface 6a' is impacted. It will act on the body d and cause damage to the body d. It transforms into hope.

  The weight members 20 and 21 and the impact action pieces 14, 22 and 23 are attached on one end side provided with screw holes 20 b ′, 21 b ′, 14 b ′, 22 b ′ and 23 b ′ to be screwed into the screw portion 19. Although it is comprised with the collars 20b, 21b, 14b, 22b, and 23b and the action part pieces 20a, 21a, 14a, 22a, and 23a on the other end side, it does not need to be limited to the illustrated form, and has a certain weight. By doing so, there is no inconvenience even if the weight is used as a weighting action as in the case of the impact action piece 4 detachably assembled to the main cylinder 1 side.

  The impact acting piece 4 attached to the main cylinder 1 side is forcibly pulled away from the cylindrical main body 1, that is, the assembly part 5 against the spring bias of the leaf spring 10, but is limited to this form. There is no need, and if various things like the impact acting piece 4 attached on the side of the insertion rod 6 are prepared, the work can be performed according to the site, and the configuration ( As long as the function is different, it is possible to use an action piece (including a weight) twice as many as usual.

  29 is a regulating member screwed into the cylindrical main body 17a of the retaining member 17, and when not in use, the leading end of the regulating member 29 is engaged with a circumferential groove 28 provided in the fitting rod 6. The movement of the fitting insertion rod 6 along the main cylinder 1 can be restricted and inconvenience at the time of carrying can be prevented.
