[0043] Next, in combination with the specific embodiments of the present utility model, the technical solutions in the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0044] As Figures 1-5 shown, a carriage lock structure of a portable printer according to the present utility model includes an ink cartridge fixing bracket 1, a printer housing 2 and a button 3.

[0045] Among them, one end of the ink cartridge fixing bracket 1 is used to be fixed on the carriage, and the other end is used to fix the ink cartridge. The ink cartridge fixing bracket 1 and the carriage are both arranged in the printer housing 2. As Figure 5 shown, this carriage lock structure of the portable printer is applied in a portable printer. In the illustrated example, the printer housing 2 is installed on the side of the printer, and the moving direction of the carriage is the left - right direction.

[0046] As Figure 3 shown, a first hook portion 101 is arranged on the side of the ink cartridge fixing bracket 1; a through hole 201 is arranged through the side of the printer housing 2 in the left - right direction; the button 3 is slidably arranged on the through hole 201 in the front - rear direction; a second hook portion 301 is arranged on the side of the button 3, and the second hook portion 301 is arranged inside the printer housing 2. The button 3 is used to drive the selective engagement or separation of the second hook portion 301 and the first hook portion 101.

[0047] When the printer needs to be moved, move the button 3 backward so that the second hook portion 301 is hooked to the first hook portion 101 to achieve locking. As Figure 2 shown, in the locked state, the ink cartridge fixing bracket 1 is fixedly connected to the printer housing 2. Since the carriage is fixedly connected to the ink cartridge fixing bracket 1, when the ink cartridge fixing bracket 1 is fixed, the carriage is also fixed accordingly. During the movement process, it is not easy to cause the carriage to shift, and thus it is not easy to cause the ink droplets of the ink cartridge to splash, and it is not easy to cause damage to the printer.

[0048] When printing is required, move the button 3 forward so that the second hook portion 301 is separated from the first hook portion 101 to achieve unlocking. As Figure 3 shown, in the unlocked state, the second hook portion 301 moves to the front of the first hook portion 101 and the two do not contact each other. Therefore, the carriage can drive the ink cartridge fixing bracket 1 to translate left and right.

[0049] As Figure 2 shown, the above-mentioned carriage lock structure of the portable printer further includes a slot sensor 4. Among them, the slot sensor 4 is fixedly arranged on the printer housing 2; a light blocking portion 302 is arranged on the side of the button 3, and the light blocking portion 302 selectively enters or leaves the inner side of the slot of the slot sensor 4 along the front-rear direction.

[0050] The main function of the slot sensor 4 is to detect the presence, position and motion state of an object through the optical principle, so as to realize the control and management of the automation equipment. It usually consists of a light emitter and a receiver, which are installed face to face on both sides of the slot. When an object passes through the slot, it will block the light and trigger the response of the sensor; in the carriage lock structure of this portable printer, the slot sensor 4 is electrically connected to the central control unit of the printer. When in the locked state, as Figure 2 shown, when the light blocking portion 302 is inside the slot of the slot sensor 4, the slot sensor 4 sends a locking signal to the central control unit of the printer, and the central control unit processes the signal. At this time, the printer does not perform subsequent printing work to prevent damage to the printer when performing a printing task in the locked state; as Figure 3 shown, in the unlocked state, the light blocking portion 302 moves out of the inner side of the slot of the slot sensor 4, and the slot sensor 4 sends an unlocking signal to the central control unit of the printer, and the central control unit processes the signal. At this time, the printer can perform subsequent printing work, ensuring the safety and reliability of the printer during the movement and use process.

[0051] In the carriage lock structure of this portable printer, the button 3 includes a dial plate 31, a buckle 32 and a lock catch 33. Among them, as Figure 3As shown, a card slot 3301 is provided on one side of the latch 33. The card slot 3301 is rectangular, and anti-slip lines are provided on its slot wall. A second hook portion 301 and a light shielding portion 302 are provided on the latch 33.

[0052] As Figure 3 shown, the dial 31 is slidably arranged in the through hole 201 in the front-rear direction. When the dial 31 is moved, the surfaces on the upper and lower sides of the dial 31 are slidably matched with the hole wall of the through hole 201. To facilitate the movement of the dial 31, anti-slip lines are provided on the side of the dial 31 away from the buckle 32.

[0053] As Figure 2 and Figure 3 shown, the buckle 32 penetrates through the through hole 201. One end of the buckle 32 is fixedly connected to the dial 31, and the other end is inserted and fixed in the card slot 3301. Specifically, a flange 2011 is provided on each of the upper and lower sides inside the through hole 201, and a gap for the buckle 32 to pass through is reserved between the two flanges 2011. The through hole 201 forms a counterbore structure through the two flanges 2011. The dial 31 is slidably matched in the through hole 201 and forms a left-right limit structure with the flange 2011. When one end of the buckle 32 is embedded in the card slot 3301 and tightened, the button 3 remains in the through hole 201. At this time, the button 3 can only slide back and forth in the through hole 201 and cannot move left and right.

[0054] As Figure 2 shown, the latch 33 is provided above the groove type sensor 4. The notch of the groove type sensor 4 faces the ink cartridge fixing bracket 1. The light shielding portion 302 is provided at the bottom of the latch 33. Specifically, the light shielding portion 302 is in the shape of an L-shaped plate. One end of the light shielding portion 302 is fixedly connected to the latch 33, and the other end faces the rear of the ink cartridge fixing bracket 1. When unlocking, the light shielding portion 302 is outside the groove of the groove type sensor 4. When locking, the light shielding portion 302 is inside the groove of the groove type sensor 4.

[0055] In the above structure, the buckle 32 is slidably arranged horizontally between the two flanges 2011. As Figure 2As shown in the figure, V-shaped groove-like positioning grooves 2012 are provided at opposite ends of two flanges 2011, and arc-shaped protruding positioning protrusions 2013 are provided on the buckle 32. The positioning protrusion 2013 selectively enters or exits the positioning groove 2012 in the front-back direction. Specifically, the positioning groove 2012 includes a locking positioning groove and an unlocking positioning groove. Among them, the locking positioning groove is provided at the rear side of the flange 2011, and the unlocking positioning groove is provided at the front side of the flange 2011. When unlocking, move the dial 31 forward. The dial 31 drives the buckle 32 to move forward, and the buckle 32 drives the positioning protrusion 2013 to enter the unlocking positioning groove. When locking, move the dial 31 backward to make the buckle 32 drive the positioning protrusion 2013 to enter the locking positioning groove. The positioning protrusion 2013 is an elastic protrusion. During the moving process, the positioning protrusion 2013 abuts against the flange 2011 and can slide on the flange 2011. The above structure is used to realize the position positioning when the button 3 slides back and forth, and improve the feel when operating the button 3.

[0056] In the above portable printer carriage lock structure, both the first hook portion 101 and the second hook portion 301 are in the shape of an L-shaped plate. Among them, one end of the first hook portion 101 is fixedly connected to the side portion of the ink cartridge fixing bracket 1, and the other end faces the front of the ink cartridge fixing bracket 1; one end of the second hook portion 301 is fixedly connected to the side portion of the lock catch 33, and the other end faces the rear of the ink cartridge fixing bracket 1. This structure facilitates the mutual engagement of the first hook portion 101 and the second hook portion 301.

[0057] The usage method of a portable printer carriage lock structure of the present invention is as follows:

[0058] First, when it is necessary to move the printer, move the button 3 backward to engage the second hook portion 301 with the first hook portion 101 to lock the ink cartridge fixing bracket 1 and the printer housing 2.

[0059] When printing is required, move the button 3 forward to separate the second hook portion 301 from the first hook portion 101 to unlock the ink cartridge fixing bracket 1 and the printer housing 2.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
