Description
Technical Field
[0001] This utility model relates to the field of inkjet printer structure technology, specifically a modular handheld inkjet printer that is easy to disassemble. Background Technology
[0002] Handheld inkjet printers, also known as portable inkjet printers, are a type of convenient inkjet printer. They can be carried around for printing, are lightweight, and are easy to operate. Handheld inkjet printers differ from inline inkjet printers; they are suitable for companies with low production speed requirements, such as when processing parts that need to have barcodes printed on them.
[0003] Handheld inkjet printers come in two types: direct grip and handheld with a handle. The choice depends on the needs. For example, patent publication number CN 218084776 U discloses a handheld inkjet printer, which includes an integrally molded housing, a small embedded encoder movably mounted on the housing, multiple auxiliary wheels movably mounted on the housing, an ink cartridge protection device on the top of the housing, inkjet printing holes on the housing, multiple holes on the side wall of the housing opposite to the inkjet printing hole and a hinged cover plate, and an anti-slip handle on the bottom of the housing.
[0004] Its shell adopts an integrated mold design. The integrated design makes it inconvenient to disassemble. When in use, the components need to be inserted from the opening, and after being inserted, they need to be connected accordingly. The fixed shell makes the installation and connection very cumbersome, and also brings inconvenience to later use and maintenance.
[0005] Its handle has a fixed structure, which limits its usability, although it is convenient for holding and operating for a long time. This design is more suitable for work environments that require frequent movement or coding in different positions. However, in confined spaces or scenarios requiring delicate operations, operators may need to perform precise coding operations within a limited space, and a handle-less design may provide better flexibility.
[0006] Alternatively, it can be used in scenarios requiring precise operation, such as when marking electronic components or small crafts. In such cases, the operator may need to control the equipment more carefully to ensure the accuracy and stability of the marking. Holding the device directly makes it easier to control.
[0007] Existing technologies also employ simple snap-fit and clip-on detachable methods at the bottom of the inkjet printer body. However, unstable grip during use can cause the device to shake, resulting in misaligned and chaotic printed patterns. This leads to poor stability in inkjet printing when handheld, failing to meet usage requirements. Utility Model Content

The upper end of the rear clamping seat 22 is provided with guide plates 222 on both sides that engage with the first guide groove 1111, and the rear end of the rear clamping seat 22 is provided with a slot 223 that engages with the rear end of the snap-fit plate 1116, as well as a limiting head 224 that elastically engages with the front end of the snap-fit groove 14.
[0037] When in use, first fix the front cover, rear cover and middle fixing shell. At this time, the bottom locking groove is also formed. Then, hold the corresponding half of the handle shell of the front guide seat and insert it into the front end of the locking groove. At this time, the guide plate of the front guide seat is guided and limited by the first guide groove. Push it to the back of the locking groove. Then hold the guide connecting seat. The guide plates on both sides of the guide connecting seat are guided and engaged with the second guide groove. At this time, the front end of the protruding locking plate under the guide connecting seat is inserted into the locking groove of the rear locking seat for fixation.
[0038] Then, hold the other half of the handle housing corresponding to the rear clamping seat and insert it into the front end of the clamping groove. At this time, the second guide plate and the first guide groove are guided and limited. After being pushed into place, the rear end of the clamping plate is inserted into the second clamping groove below the rear end of the rear clamping seat for fixation. At the same time, the rear clamping seat is inserted into the groove of the clamping groove and is elastically inserted and limited by the rear cover plate, which facilitates the disassembly and assembly of the clamping seat.
[0039] To disassemble the handle, first hold the inkjet printer body with one hand and the handle with the other. Use your thumb to pry the limit clip head to disengage it from the slot. Then pull the handle half to detach the rear clamping seat from the slot and the clamping plate.
