Abstract

PURPOSE:To easily mount a printing head, by constituting a clamp lever so that a V-shape part is provided to the top part thereof and corrugated bed pieces are allowed to protrude from both side parts thereof in opposed relationship and mount parts are formed to the lower end parts of both side parts thereof. CONSTITUTION:The printing head 21 mounted on a carrier 22 is fixed to a carrier 22 by a clamp lever 11. The clamp lever 11 is composed of a spring material and formed into a gate shape and equipped with a V-shape bent part 12, corrugated bent pieces 13, a mount hole 14 and a mount groove 15. The V-shape bent part 12 is brought into contact with the top part of a printing head 21 to press said head in an up and down direction. The corrugated bent pieces 13 are allowed to protrude from both side parts of the clamp lever in opposed relationship and engaged with the groove of the groove 25 of the carrier 22 to perform the pressing of the head in a before and behind direction and the mount hole 14 is engaged with a left-hand pin 26 while the mount groove 15 is engaged with a right-hand pin 26. Therefore, the mount groove 15 is engaged with the pin 26 and the clamp lever 11 is rotated around the mount groove 15 and the corrugated bent pieces 13 are engaged with the groove 25 and the mount hole 14 is engaged with the pin 26 to press the top part of the printing head 21 by the V-shape bent part to hold a fixed state.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a print head clamp structure, and more particularly to a print head clamp structure for a printing device for fixing a print head on a carrier.

[Prior Art] In the print head clamp structure of a conventional printing device, a carrier on which the print head is mounted is provided with a plurality of guide pins and screw holes for determining the print head mounting position, and the print head is mounted on the carrier in alignment with the guide pins. After positioning the print head, the print head was held by the carrier by tightening the screw through the screw hole.

[Problems to be Solved by the Invention] In the conventional print head holding structure described above, the carrier on which the print head is mounted is provided with a plurality of guide pins and screw holes for determining the print head mounting position.
After positioning with a guide bin, the screws were tightened, so tools such as a screwdriver were required to attach and install the print head, and since the screws for attachment were small, there were problems such as falling or losing them. there were.

In addition, it is necessary to attach a guide bin to the carrier and process screw holes, which is a disadvantage in terms of cost.

[Means for Solving the Three Problems] The present invention has been made to solve the above-mentioned problems, and as a means for solving the problem, the present invention provides a structure in which the print head placed on a carrier is shaped like a gate made of spring material. The print head clamp structure is fixed to the carrier with a clamp lever, and the clamp lever has a V at the top for abutting against the top of the print head and holding it down in the vertical direction.
A curved part, a wave-shaped curved piece protruding oppositely from both sides to engage with the groove of the carrier and press it in the front and back direction, and a lower end part of both sides to engage and fix the carrier with a bottle. The configuration includes a formed mounting portion.

[Example] Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a clamp lever used in a print head clamp structure according to an embodiment of the present invention, and FIG.
FIG. 3 is a perspective view showing a state in which the print head is fixed using the clamp lever shown in the figure.

In this print head clamp structure, a print head 21 placed on a carrier 22 is fixed to the carriers 2, 2 by a clamp lever 11.

The carrier 22 carries the print head 21 to a specified printing position, is guided through a guide shaft 23, and is configured to receive power for movement through a belt 24. Furthermore, grooves 25 facing outward are formed on both sides of the print head 217Fr mounting position of the carrier 22, and a mounting pin 26 is formed protrudingly below the grooves 25. One bottle 26 (on the right side in the figure) protrudes forward, and the other bottle 26 (not shown) on the left side in the figure protrudes to the left side.

The clamp lever 11 is made of a spring material and has a gate shape, and includes a V-shaped curved portion 12, a wave-shaped curved piece 13, and a mounting hole 14 and a mounting groove 15 as a mounting portion.

The V-shaped bent portion 12 is formed at the top and is adapted to abut against the top of the print head 21 and press it in the vertical direction.

The wave-shaped curved pieces 13 are made to protrude from both sides and engage with the grooves 25 of the carrier 21 to press the carrier 21 in the front-back direction. The mounting hole 14 is adapted to engage with the bin 26 on the left side in the figure, and the mounting groove 15 is adapted to engage with the bin 26 on the right side in the figure.

Therefore, by engaging the mounting groove 15 with the pin 26, rotating the clamp lever 11 around the mounting groove 15, and fully engaging the waveform curved piece 13 with the pin 25 and the mounting hole 14 with the pin 26, a V-shaped The curved portion 12 presses against the top of the print head 21 to keep it fixed.

In addition, 16 shows a knob part for attachment and detachment.

[Effects of the Invention] As explained above, the present invention provides a print rad clamp structure in which a print head placed on a carrier is fixed to the carrier by a gate-shaped clamp lever made of a spring material, and the clamp lever is , a V-shaped curved portion at the top that comes into contact with the top of the print head to press it in the vertical direction, and a wave-shaped curve that protrudes oppositely on both sides to engage with the groove of the carrier and press it in the front and back direction. Since the design has two mounting parts formed at the lower ends of both sides to engage and fix the carrier bottle, in order to fix the printing print head to the carrier, it can be moved forward and backward by - degree operation.・It has the advantage of being able to be held and fixed from the top and bottom simultaneously, and can be easily installed without the need for tools such as a screwdriver.
