【Example】

 The drawings show a preferred embodiment of the present invention, in which a storage part 3 for a bobbin winding drum 2 is provided in the ink jar body 1, and a bobbin winding drum 2 having a spring spring 4 for automatic winding therein is housed in this storage part 3. Then, the ink thread 5 is wound around the outer circumference of the thread winding drum 2, and the ink thread 5 is pulled out to the outside via the ink insertion portion 6 provided in the ink jar body 1, and the chalcone 11 is attached to the tip of the ink thread 5. In the automatic winding type ink bottle a, an opening portion 20 for accommodating the bobbin winding drum 2 is provided in the storage portion 3 of the bobbin winding drum 2 formed in the head case body 18, and the operating portion 2 "of the bobbin winding drum 2 is provided in this opening portion 20". A cover lid 21 provided with an operation opening window 21 "for exposing is rotatably fitted, and the peripheral edge of the cover lid 21 and the peripheral edge of the opening 20 of the storage part 3 of the head case body 18 are fitted. A rotation locking mechanism 22 having an engaging structure for fixing the cover lid 21 to the storage portion 3 is provided at a portion facing the portion. There.

The rotation locking mechanism 22 will be described in detail.

A fitting step portion 24 is provided in the opening 20 of the head case body 18, and an engaging projection is provided on the outer peripheral surface of the tip of the fitting step portion 24 at an interval of about 120 ° in the outer peripheral direction as shown in FIG. The pieces 25, 25, 25 are integrally projected, and a fitted step portion 27 into which the fitting step portion 24 of the head case body 18 is fitted is provided in the fitted portion of the cover lid body 21. As shown in FIG. 4, corresponding engagement protrusions 28, 28, 28 are integrally provided on the inner peripheral surface of the inner peripheral surface 27 at a corresponding interval of about 120 ° so as to project into the insertion step portion 24. When the fitting step portion 27 is fitted, the relationship between the engagement projection piece 25 and the corresponding engagement projection piece 28 is provided so as to be fitted to each other at the positions shown in FIGS. When the cover lid 21 is fitted onto the main body 18 and the cover lid 21 is rotated, the corresponding engaging projection 28 of the cover lid 21 is fitted into the back of the engaging projection 25 of the head case body 18. , The cover body 21 is attached to the head case body 18. An example is shown in which a rotation locking mechanism 22 provided so as to be fixedly fixed is adopted. Further, a fitting hole 16 is provided in the center of the inside of the operating portion 2 "of the bobbin winding drum 2, and a distal end of a locking shaft 17 to which a base end portion of the mainspring spring 4 is fixed is rotatably fitted into the fitting hole 16 and is engaged. The bobbin is supported by supporting the flange portion 17 'at the other end of the stop shaft 17 and the outer periphery of the operating portion 2 "by the supporting opening portion 18' of the head case body 18 and the operating opening window 21" of the cover lid 21. The case where the drum 2 is rotatably provided in the storage unit 3 is illustrated.

Reference numeral 30 in the drawing is a sponge packing for fitting the cover lid 21 and the head case body 18 in a tensioned state in the axial direction.

Since the present embodiment is configured as described above, the fitting step portion 27 of the cover lid body 21 is fitted to the fitting step portion 24 of the opening 20 of the head case body 18, and the cover lid body 21 is fixed. When the cover lid 21 is rotated clockwise, the corresponding engagement protrusion 28 of the cover lid 21 and the engagement protrusion 25 of the head case body 18 mesh with each other, and the cover lid 21 is assembled and fixed to the head case body 18.

When the cover lid 21 is rotated in the reverse direction, the cover lid 21 can be removed from the head case body 18, and the spool drum 2 can be removed from the storage portion 3.

Next, the illustrated ink jar shows an embodiment in which the following structure is also added.

A storage section 3 for the bobbin winding drum 2 is provided in the black urn body 1, and the bobbin winding drum 2 having a self-winding spring 4 for automatic winding therein is stored in the storage section 3 and the black thread 5 is provided on the outer periphery of the bobbin winding drum 2. In the automatic winding type ink bottle a in which the ink thread 5 is wound and pulled out to the outside through the ink insertion portion 6 provided in the ink bottle body 1, and a calco 11 is attached to the tip of the ink thread 5, An opening 20 for accommodating the thread winding drum 2 is provided in the storage portion 3 of the thread winding drum 2 formed in the main body 18, and a cover lid 21 exposing the operation portion 2 "of the thread winding drum 2 is rotatably provided in the opening 20. When the cover lid 21 and the opening 20 of the storage portion 3 are provided with a rotation locking mechanism 22 for fixing the cover lid 21 to the storage portion 3, when the cover lid 21 is further rotated, the bobbin winding drum. 2. Fix the rotation of 2 immovably and cover the black thread stop mechanism 23 that makes it impossible to pull out the black thread 5. For black yarn stop mechanism 23 provided on the opening 20 of the storage section 3 and the lid 21 will be described.

Assembling of the cover lid 21 on the inner side surface of the engaging projection 25 of the head case body 18 of the rotation locking mechanism 22 gradually advances inward from a predetermined angle α in the assembling rotation direction of the cover lid 21. When the slope portion 29 is provided, the cover lid body 21 is pivotally locked and fixed to the head case body 18, and then the cover lid body 21 is further rotated, the corresponding engagement projection piece 28 becomes the slope portion 29 of the engagement projection piece 25. The cover lid 21 rotates in the direction of the head case body 18 while gradually moving slightly, and the side wall inner end surface 21 'of the cover lid 21 presses the rim portion 2'of the winding drum 2. Then, the rim portion 2'on the head case body 18 side of the bobbin drum 2 is brought into contact with the convex inner wall surface 18 "of the head case body 18, so that both side surfaces of the bobbin drum 2 are convex to the side wall inner end surface 21 '. Since it is held so as to be attached to the inner wall surface 18 ″, the rotation of the bobbin winding drum 2 is stopped and the black ink thread 5 is fixed to the black ink bottle body 1.

Since the present embodiment is configured as described above, the cover lid 21 is fixed to the storage portion 3 by the rotation locking mechanism 22 and used as a normal ink pot.

When the ink thread 5 drawn out from the ink jar body 1 is cut or tangled during operation or when the ink thread 5 is reattached to the calco 11, the cover lid 21 is further rotated to cause the ink thread stopping mechanism. When the bobbin winding drum 2 is fixed so as not to rotate by 23 and the black ink thread 5 is fixed to the black ink bottle body 1 so as not to be pulled out, the black thread 5 is not wound on the bobbin winding drum 2 so that the repair work is easy. Becomes Further, when the ink is used for black ink striking work or plumb bob, the black ink thread 5 can be fixed without pressing the operating portion 2 "by hand, and thus the work is a plumb bob which also has a good workability.

Next, when the cover lid 21 is rotated in the opposite direction, the ink thread stopping mechanism 23 is released, and the ink thread 5 can be pulled out from the ink bottle body 1.

When the cover lid 21 is further rotated in the reverse direction, the cover lid 21 can be removed from the storage portion 3, and the bobbin winding drum 2 can be taken out from the storage portion 3.

In the figure, reference numeral 7 is a grounding portion, and reference numeral 19 is a tip of the calco 11 that is struck against a pillar or a wall body. It is an indicator when it is used as a plumb bob, which allows you to mark the surface of the floor or the work piece and check the verticality of columns and walls as shown in.

[Effect of device]

 Since the present invention is configured as described above, it is possible to easily assemble and separate the head case body and the cover lid by the rotary locking mechanism having the locking structure. If the wound ink thread is cut or tangled, or if the ink fountain breaks down, easily remove the cover lid from the head case body, take out the winding drum from the storage section, and restore the original state. It is a very useful ink bottle that can be repaired, repaired, and inspected inside the head case.
