The unidirectional wire winding scriber shown in fig. 1-3 and 7-8 comprises a housing 100, a wire wheel 200 arranged in the housing, an ink wire 300 wound on the wire wheel and led out of the housing, and a crank 400 positioned outside the housing and used for driving the wire wheel to rotate.

As shown in fig. 3, 7-8, the casing 100 includes a first case 110, a second case 120, a cover 130, and an ink cartridge 140. The second housing 120 is located at the front side of the first housing 110, and the second housing 120 and the first housing 110 are assembled together by a fastener, and a first accommodating chamber 150 is formed between the second housing and the first housing. The upper ends of the second casing and the first casing which are assembled together are provided with mounting holes, and the ink box 140 is clamped in the clamping holes and is convenient to detach. The ink box is used for containing ink and inking the ink line led out from the ink box. In fig. 8, a thread sleeve 124 is further disposed in the second housing 120 for guiding the ink thread to prevent the ink thread from being misplaced, and the thread sleeve 124 is preferably made of an abrasion-resistant material to increase abrasion resistance. The first casing 110 has a first pivot 111 inside, and the second casing 120 has a second pivot 121 inside, and for material saving, the first pivot and the second pivot are both in the shape of a sleeve, and the second pivot provides a space for installing a first transmission shaft, which will be described below, therebetween. The cover 130 is mounted to the front side of the second housing 120 by fasteners, and a second receiving chamber 160 is formed between the cover 130 and the second housing 120. The second housing 120 is provided with a first through hole 122, and the cover 130 is provided with a second through hole 131.

As shown in fig. 3, 7-8, and 9-10, the pulley 200 is in the shape of a wheel disc, and has a winding drum 210 and baffles 220 at both ends of the winding drum. The rear end of the winding drum 210 is provided with a first shaft hole 211, the front end of the winding drum 210 is provided with a second shaft hole 212, and as shown in fig. 9, the second shaft hole 212 is a stepped hole and is provided with a first mounting groove 213 and a second mounting groove 214 therein. As shown in fig. 10, a pawl 521 is installed in the first installation groove 213, and a first elastic member 522, which is a helical compression spring supported on the pawl, is installed in the second installation groove 214. The pulley 200 is placed in the first accommodation chamber 150, the first mounting groove 213 is rotatably engaged with the first pivot 111, and the second mounting groove 214 is rotatably engaged with the second pivot 121, so that the pulley can rotate.

As shown in fig. 3 and 7-8, the ink line 300 is wound on the reel 200, passes through the line sleeve 124 and the ink box 140 and is led out of the casing, and a hook 301 is connected to the outer end of the ink line, the hook is hooked at a corresponding position when in use, the hook is convenient for pulling out the ink line, prevents the outer end of the ink line from being drawn into the casing, and is clamped on the casing when the scriber is accommodated. In the figure, the ink lines wound on the reel are omitted for convenience of illustration.

The handle 400 is used to wind the drawn wire by rotating with the reel 200. Therefore, the rocking handle can be directly connected with the wire wheel to drive the wire wheel to rotate. The reel can also be driven to rotate by a transmission piece or a transmission mechanism connected between the rocking handle and the reel.

In order to realize the purpose of the utility model, a one-way transmission mechanism is arranged between the rocking handle 400 and the reel 200, the one-way transmission mechanism is provided with a first input end and a first output end, the first input end is in transmission connection with the rocking handle, and the first output end is in transmission connection with the reel.

Specifically, as shown in fig. 4, the one-way transmission mechanism is a ratchet and pawl mechanism 500, which includes a first transmission shaft 510 and a first sleeve 520. First shaft sleeve 520 is arranged on reel 200, specifically, second shaft hole 212 of reel 200 is used as first shaft sleeve 520, and as described above, pawl 521 is assembled in second shaft hole 520, that is, the pawl is assembled in the first shaft sleeve. The first transmission shaft 510 is in transmission connection with the rocking handle 400, and the ratchet wheel 511 is arranged on the first transmission shaft 510. The pawl 521 is brought into contact with the ratchet 511 by the elastic force of the first elastic member 522. When the first transmission shaft 510 is driven to rotate counterclockwise by the crank as shown in fig. 4, the ratchet wheel 511 rotates counterclockwise, and the ratchet wheel 511 drives the reel 200 to rotate counterclockwise through the pawl 521 for winding the ink line drawn out of the casing. When the first transmission shaft 510 is driven by the crank to rotate clockwise as shown in fig. 4, the ratchet 511 rotates clockwise, the pawl 521 slips on the ratchet 511 and makes a rattling sound, so that the crank spins, the spool does not rotate, and the ink line is not wound. In specific implementation, the matching direction of the pawl and the ratchet can be changed, so that the action opposite to the rotation direction shown in fig. 4 is realized. Therefore, the unidirectional torque transmission is realized by the ratchet-pawl mechanism. Therefore, the ink line can be wound without rotating the wire wheel when the rocking handle is rocked to one direction and the ink line can be wound without rotating the wire wheel when the rocking handle is rocked to the other direction. In fig. 4, first transmission shaft 510 serves as a first input end, first sleeve 520 serves as a first output end, and first sleeve 520 is formed integrally with pulley 200.

In addition, in the specific implementation, the first transmission shaft can be used as the first output end, and the first sleeve can be used as the first input end, that is, the first transmission shaft and the first sleeve are shifted.

In the figure, the first transmission shaft 510 is in transmission connection with the rocking handle 400 through the speed increasing transmission mechanism 700, thereby realizing speed increasing. The speed-increasing transmission mechanism 700 is fitted in the second accommodation chamber 160.

As shown in fig. 5 and fig. 7-8, the speed-increasing transmission mechanism 700 has a second input end 710 and a second output end 720, the rotation speed of the second output end 720 is greater than that of the second input end 710, and the speed-increasing transmission mechanism is connected in series with the one-way transmission mechanism. Specifically, the speed increasing transmission mechanism is a planetary gear set including a rotating ring gear 730, a planetary gear 740, a sun gear as the second output 720, and the second input 710. The second input 710 is shaft-like and drivingly connected to the rotating ring gear 730, and the planetary gears 740 are fitted on the hub 123 of the second housing 120 and simultaneously mesh with the rotating ring gear 730 and the sun gear. The second output end 720 is integrated with the first input end, i.e. a sun gear is arranged at the front end of the first transmission shaft 510, a ratchet wheel 511 is arranged at the rear end of the first transmission shaft 510, and the second output end, the first input end and the first transmission shaft are embodied as one component. Thus, the rotation of the second input is changed to the reverse, increasing rotation of the second output by the planetary gear set. When the rocking handle is rocked clockwise as shown by an arrow in fig. 2, the anticlockwise speed-up rotation of the wire wheel shown in fig. 4 can be realized. On the contrary, when the rocking handle is rocked counterclockwise as shown in fig. 2, the rocking handle idles due to the presence of the unidirectional transmission mechanism as described above, and the pulley does not rotate.

The second input 710 passes through the second through hole 131 of the cover 130 and is drivingly connected to the handle 400 by the pin 401, so that the second input is rotated by swinging the handle. Meanwhile, the rocking handle 400 can rotate around the pin 401 for being folded and stored into the housing. When the rocking handle needs to be rocked, the rocking handle can be rotated by 180 degrees around the pin shaft as shown in the figure.

In view of the fact that the first output end is the first shaft sleeve, the first shaft sleeve and the wire wheel are made into a whole, and therefore the transmission connection of the first output end and the wire wheel is direct transmission.

Since the second output, the first input and the first transmission shaft are embodied as one component, the transmission connection of the second output to the first input is embodied as a direct transmission. Also, in the assembled relationship, the first transfer shaft passes through the first through hole in the second housing. In specific implementation, the length of the second output end and the length of the first input end are changed to form a first through hole through which the second output end or the first input end passes.

Because the speed-increasing transmission mechanism is arranged between the first input end and the rocking handle, the transmission connection between the first input end and the rocking handle is indirect transmission.

Further, as shown in fig. 3, 6, and 11-12, the rotating ring gear 730 is in a disk shape, the second input end 710 is axially movably connected with the center of the rotating ring gear 730 through spline transmission, a helical compression spring is disposed between the second input end 710 and the first transmission shaft 510 as a second elastic element 750, the second input end 710 is held at the position of the spline transmission connection shown in fig. 11 by the elastic force of the second elastic element 750, and is used for swinging the rocking handle to take up wire; pressing the second input 710 axially backward overcomes the force of the second resilient element 750, as shown in fig. 12, to disengage the spline drive connection, and at this time, to prevent the rocking handle from rotating with the reel when the ink line is being pulled out.

As shown in fig. 3, the second input end 710 cannot be removed from the second through hole by its circumferential step abutting against the inner surface of the cover 130. The rotary ring gear 730 is restrained in the second accommodation space 160 by the cover 130 and the second housing 120 to maintain its working position; the planetary gears 740 are held between the rotary ring gear 730 and the second housing 120 by the rotary ring gear 730 and the second housing 120 to maintain the engagement with the rotary ring gear 730; first transmission shaft 510 is located at the matching position with reel 200 and planetary gear 740 by the elastic force of the second elastic element, i.e. second output end (sun gear) 720 on first transmission shaft 510 is meshed with planetary gear 740, ratchet 511 on first transmission shaft 510 is matched with pawl 521 on reel 200. The matching relation of the transmission parts is maintained in turn.

Additionally, FIG. 4a shows another unidirectional drive mechanism, which is a roller transfer mechanism 600 that can be substituted for the ratchet-pawl mechanism 500 of FIG. 4. The roller transmission mechanism comprises a second transmission shaft 610, a second shaft sleeve 620 and a roller 630, wherein a first extrusion surface 611 is arranged on the outer surface of the second transmission shaft 610, a second extrusion surface 621 is arranged on the inner wall of the second shaft sleeve 620, the second shaft sleeve 620 is sleeved outside the second transmission shaft 610, a circumferential extrusion gap 640 is formed between the first extrusion surface 611 and the second extrusion surface 621, the circumferential extrusion gap 640 gradually decreases along the counterclockwise direction, and the roller 630 is arranged in the circumferential extrusion gap. In fig. 4a, a second transmission shaft 610 is used as a first input end and is in transmission connection with the rocking handle, and a second shaft sleeve 620 is used as a first output end and is integrally made with the reel. Therefore, when the second transmission shaft 610 is driven by the rocking handle to rotate in the counterclockwise direction, the roller 630 moves in the counterclockwise direction due to friction of the second transmission shaft, and is pressed at the end with the smaller circumferential extrusion gap 640, the second transmission shaft 610 transmits force to the second shaft sleeve 620 through the roller 630, and the second transmission shaft 610 drives the second shaft sleeve 620 and the wire wheel to rotate in the counterclockwise direction through the roller 630, so that the ink wire pulled out of the shell is wound. When the second transmission shaft 610 is driven by the rocking handle to rotate clockwise, the roller 630 moves clockwise due to friction of the second transmission shaft, enters the end with the larger circumferential extrusion gap 640, does not transmit force to the second shaft sleeve 620, the rocking handle idles, the wire wheel does not rotate, and the ink wire is not wound. In specific implementation, the size and direction of the circumferential extrusion gap can be changed to realize the action opposite to the rotation direction shown in fig. 4 a. Thereby realizing unidirectional torque transmission by the roller transmission mechanism. Therefore, the ink line can be wound without rotating the wire wheel when the rocking handle is rocked to one direction and the ink line can be wound without rotating the wire wheel when the rocking handle is rocked to the other direction.

Specifically, the first pressing surface 611 is a circumferential surface, the second pressing surface 621 is a non-circumferential surface, and the distance between the non-circumferential surface and the axial center of the first sleeve gradually decreases in the counterclockwise direction. In a specific embodiment, the second pressing surface may be a circumferential surface, and the first pressing surface may be a non-circumferential surface.
