Description

Improvement of ink automatic take-up device

The present invention relates to a tilting member having a front and rear extending cantilever and an abutting arm disposed in an intermediate shaft of the ink fountain, which can be positioned after swinging so that the end of the abutting arm and the continuous tooth portion on the reel are not in contact with each other. When the reel take-up wire is electrically driven, it is smoother and unobstructed.

The ink fountain used in civil engineering work is a tool for scribing, and the ink fountain also has an electric retracting gauge, such as the patents 227697, 235548, M428822, etc. announced by Taiwan, and the inventor of the present invention previously applied No. 105201124 The patent (hereinafter referred to as the previous case), the main improvement is that a warp-turning warping member installed in the ink fountain is provided, and a pressing member capable of pressing the ink line is pivoted at the end of the front cantilever arm, and The end of the rear extension arm can be continuously slid by the continuous tooth portion provided on the reel, so that when the reel is rotated to take up the ink line, the abutting arm is continuously pulled downward to make the pressing member not lifted correctly. The ink line is pressed; on the contrary, when the ink line is pulled out and the reel is rotated in the reverse direction, the resisting arm is continuously pushed upward, so that the pressing member keeps pressing the ink line and continuously dipped the ink, thereby achieving automatic inking. effect.

However, in the foregoing case, when the reel is taken up, in order to prevent the pressing member from pressing the ink line, the continuous tooth portion of the reeling member should be continuously moved downward by the end of the abutting arm of the warping member. In order to allow the pressure-bearing parts to be lifted up without pressure on the ink line, the rotation of the reel is relatively resisted by the resisting arm, that is, the rotation of the reel has resistance, which may cause the following question. question:

1. Since the ink fountain itself is not large, the interior must accommodate various components necessary to accommodate the battery. The motor that can accommodate the rotation of the reel is limited in space, so that the output horsepower of the motor is small, once the reel is rotated. When the above resistance is hindered, the rotation of the reel is slowed down, and the speed of the winding is slow. Even when the power of the battery is insufficient, the reel cannot be driven to be retracted.

2. When the rotation of the reel is obstructed by the above resistance, in addition to affecting the rotation of the winding, if the driving of the motor is blocked, the power consumption of the battery supplying the power will increase sharply, resulting in less time for the battery to be powered. Short, it also affects the battery life.

The reason is that in order to improve the electric winding of the front ink drum, the end of the inner arm of the inner warping member may cause a rotation resistance to the reel, resulting in a problem that the winding is slow, or even unable to take up the line, so the present invention The elimination of the resistance when the reel is electrically driven, that is, the warping member installed in the ink fountain can be swung and positioned, and the end of the resisting arm is disengaged from the continuous tooth of the reel. The range of contact makes the rotation of the reel wheel no longer obstructed by the warping member; conversely, the warping member can be turned back to keep the anti-contact arm and the continuous toothing on the reel on the reel when the line is released. Move, so that the ink line still has the effect of automatic ink.

The technical solution adopted by the present invention to solve the technical problem is that an ink-absorbing pad which can be inked by the ink line is accommodated in front and rear of a casing, and an outer edge of the ink-receiving wire which can be driven by the electric drive a reel having a continuous tooth portion, and pivoting a pivoting member at the middle of the housing, the warping member is provided with a forward extension and a distal end thereof for restraining the pressure of the ink absorption pad The cantilever of the piece and the abutting arm which is extended and whose end can continuously move with the continuous tooth, and further A fingering arm is further disposed on the warping member, and a notch for the fingering arm to protrude from the corresponding housing is disposed on both sides of the rear end of the notch Corresponding two rotation stops, and the finger arm can be resisted by the two rotation stops or forcedly passed between them.

Therefore, when the finger lever provided on the new warping member is pushed backward, it is forcibly passed between the two rotation preventing portions at the notch, and the two rotation preventing portions are not blocked. Then, the swinging arm is kept away from the continuous tooth portion on the reel, and the reel is in an unimpeded rotation state, that is, the reel is rotated when it is electrically driven to rewind the ink line. It is smoother and the load on the motor that drives the reel can be greatly reduced, thereby reducing the consumption of electric energy.

Referring to FIG. 1 to FIG. 3 , the ink fountain of the present invention comprises a cover 11 having a front end side locking and an upper ink filling port 110 and a screw cap covering a cap, and a locking cover on the rear end side thereof. The side cover 12 and the housing 1 of the side cover 13 are arranged such that the front end side of the housing 1 is provided with upper and lower laminated pressure pad 41 and ink absorbing pad 42 and the ink line 2 is passed through the middle of the housing. The wire hole 17 is passed between the crimping pad 41 and the ink receiving pad 42 and then passed through the front end of the casing 1 to be coupled to a nail member 21.

In addition, the rear end side intermediate shaft of the casing 1 is provided with an axle 5 on which a main gear 51 is disposed, and one end of the axle 5 is coupled to a roll which is accommodated in one side of the rear end side of the casing 1. The reel 3 is wound around the ink line 2, and the outer edge of one side of the reel 3 is provided with a continuous tooth portion 31, and the other side of the rear end side of the casing 1 is further provided with a motor 8, and the motor 8 is placed thereon. A secondary gear 81 that meshes with the aforementioned main gear 51 is mounted.

Furthermore, the other end of the rotating shaft 5 is extended through the side cover 12 of the corresponding side, and another fitting portion 53 is disposed at the exposed end, and the outer side surface of the side cover 12 is concavely disposed for receiving and positioning. The receiving groove 121 of the crank handle 9 is accommodated, and the engaging hole 91 of the crank handle 9 is respectively provided with a fitting hole 91 engageable with the fitting portion 53 of the rotating shaft 5.

Moreover, between the middle of the casing 1 and the rear end of the casing cover 11, a warping member 6 is formed, which extends from the center to the rear and forwardly to extend an abutting arm 61 and a cantilever 62, respectively. The abutting arms 61 and the cantilever 62 of the front and rear of the movable member 6 can be swung up and down like a seesaw shape, and the ends of the abutting arms 61 and the continuous tooth portions 31 of the aforementioned reel 3 can be slightly in contact with each other. The end of the cantilever 62 is pivotally provided with a pressing member 7, so that the pressing member 7 can press the pressing pad 42 to cause the ink line 2 to be pinched between the ink receiving pads 41; further, The housing 11 corresponding to the warping member 6 is provided with a rotation preventing portion 112, and the rotation preventing portion 112 is disengaged from the reelable roller 3 when the warping member 6 is swung to the end of the abutting arm 61 thereof. When the continuous tooth portion 31 is out of contact with the range, the warping member 6 is prevented or caught so as not to swing back.

The above-mentioned anti-rotation portion 112 is disposed on a notch 111 opened at the upper middle of the casing 1 (ie, at the rear end of the cover 11), and is disposed corresponding to the two sides of the notch 111 adjacent to the rear end. At the same time, a finger lever 63 is extended upwardly on the warping member 6, so that the finger lever 63 can be extended from the slot 111 formed in the housing 1, and the width of the fingering arm 63 is slightly larger than the slot. 111 of the two The distance between the rotation preventing portions 112 and the fingering arm 63 can be forced to pass between the two rotation preventing portions 112 with a slight force.
