A groove is formed on the inner side surface of the first side plate 101. The first fixing structure 200 includes a spring and a top pin. One end of the top pin extends out of the groove, and the other end is arranged in the groove. The spring connects the bottom surface of the groove and the top pin. Specifically, the end of the top pin extending out of the groove is a sphere, and the diameter length of the sphere is greater than the diameter length of the connecting through hole 402; in other embodiments, the first fixing structure 200 can adopt existing structures such as a ball head plunger; the second fixing structure 300 is provided on the second side plate 102. A through hole is formed on the second side plate 102. The second fixing structure 300 includes a column body. The column body is arranged in the through hole, and both ends of the column body respectively extend out of the inner side surface and the outer side surface of the second side plate 102, and the column body can move along its axial direction in the through hole; preferably, the second fixing structure 300 further includes a spring member and a spring retaining ring. The spring retaining ring is sleeved on the column body, and the spring retaining ring is located outside the second side plate 102. The spring member connects the spring retaining ring and the end of the column body extending out of the inner side surface of the second side plate 102. In other embodiments, the spring member can also connect the spring retaining ring and the end of the column body extending out of the outer side surface of the second side plate 102; in other embodiments, the second fixing structure 300 can adopt existing structures such as a knob plunger; when the bottom cover body 100 is installed on the nozzle bottom plate 400, the end of the top pin extending out of the groove and the end of the column body extending out of the inner side surface of the second side plate 102 are respectively located in the connecting through holes 402 on two opposite side surfaces of the connecting plate 401.

[0024] The basic working principle of the protective bottom cover involved in the present utility model is as follows: When installing the protective bottom cover, move the cylinder so that the cylinder moves in a direction away from the first side plate 101, and move the end of the cylinder extending out of the inner side surface of the second side plate 102 into the through hole of the second side plate 102. The bottom cover body 100 is installed from below the nozzle bottom plate 400. Specifically, the bottom cover body 100 moves upward until the connecting plate 401 contacts the bottom plate of the bottom cover body 100. And during the upward movement of the bottom cover body 100, the side surface of the connecting plate 401 contacts the inner side surface of the side plate of the bottom cover body 100. When the end of the top pin extending out of the groove contacts the side surface of the connecting plate 401, the connecting plate 401 pushes the top pin to move in a direction away from the connecting plate 401, so that the top pin is completely in the groove. At this time, the spring is in an elastic energy storage state. When the bottom cover body 100 moves upward to the connecting through hole 402, under the action of the spring, the top pin resets and is located in the connecting through hole 402. At this time, the connecting plate 401 contacts the bottom plate of the bottom cover body 100. Then move the cylinder again, so that the cylinder extends out of the inner side surface of the second side plate 102 from the through hole and is located in the connecting through hole 402. Under the action of the top pin and the cylinder, the bottom cover body 100 is installed on the nozzle bottom plate 400; When disassembling the protective bottom cover, move the cylinder so that the cylinder moves in a direction away from the first side plate 101, and move the end of the cylinder extending out of the inner side surface of the second side plate 102 into the through hole of the second side plate 102. Then move the bottom cover body 100 downward. The connecting plate 401 can push the top pin to move in a direction away from the connecting plate 401, so that the top pin is completely in the groove. At this time, the spring is in an elastic energy storage state. And since both the top pin and the cylinder leave the connecting through hole 402 of the connecting plate 401, the bottom cover body 100 can be disassembled from the nozzle bottom plate 400.

[0025] See Figures 1 to 4 , the following further illustrates the present utility model with a specific embodiment:

[0026] In this embodiment, see Figure 1 , as a preferred design, a plurality of first fixing structures 200 are provided on the inner side surface of the first side plate 101. The plurality of first fixing structures 200 are uniformly arranged along the length extension direction of the first side plate 101. The plurality of first fixing structures 200 can improve the connection stability between the bottom cover body 100 and the connecting plate 401.

[0027] In this embodiment, see Figure 3 and Figure 4, as a preferred design, the second fixing structure 300 further includes a locking assembly. The locking assembly is arranged on the column body, and the locking assembly can lock and fix the column body on the second side plate 102. On the one hand, when the column body is located in the connection through hole 402, the position of the column body is fixed by the locking assembly, which can prevent the second fixing structure 300 from detaching from the connection through hole 402 of the connection plate 401. On the other hand, when the bottom cover body 100 is installed on the nozzle bottom plate 400, the column body is moved so that the end extending out of the inner side surface of the second side plate 102 no longer extends out of the inner side surface of the second side plate 102, and the position of the column body is fixed by the locking assembly, which is convenient for the installation between the bottom cover body 100 and the nozzle bottom plate 400.

[0028] In this embodiment, refer to Figure 1 , as a preferred design, the bottom cover body 100 is provided with four side plates. An avoidance groove 103 for avoiding the connection plate 401 is formed between any two adjacent side plates. The extending direction of the avoidance groove 103 is perpendicular to the bottom plate. When the bottom cover body 100 is installed from below the nozzle bottom plate 400, the avoidance groove 103 can prevent interference in the connection between the connection plate 401 and the bottom cover body 100, and prevent the bottom cover body 100 from being damaged during installation and disassembly.

[0029] In this embodiment, refer to Figure 1 and Figure 2 , as a preferred design, the material of the bottom cover body 100 is aluminum. The aluminum bottom cover body 100 has good surface aesthetics, and aluminum has good corrosion resistance, so that the bottom cover body 100 can maintain a long service life and is suitable for various environments.

[0030] In this embodiment, refer to Figure 1 and Figure 2 , as a preferred design, the material of the bottom cover body 100 is nylon. Nylon has high mechanical strength, good toughness, superior tensile and compressive strength, and the nylon bottom cover body 100 is relatively soft. During the installation and disassembly of the bottom cover body 100, even if the nozzle is accidentally touched, it will not cause damage to the surface of the nozzle, which can effectively protect the nozzle. And the nylon material is lighter, making it easier for the staff to install and disassemble the bottom cover body 100. At the same time, nylon also has good insulation performance, which can effectively prevent current leakage and ensure the safety of the inkjet printer equipment and the staff.

[0031] As can be seen from the above, the protective bottom cover for protecting the nozzle of the present utility model has the following beneficial effects:

[0032] By setting the first fixing structure 200 and the second fixing structure 300, the bottom cover body 100 can be quickly installed on the nozzle bottom plate 400 of the nozzle, and the bottom cover body 100 can also be quickly detached from the nozzle bottom plate 400 of the nozzle, thereby improving the working efficiency of the staff.

[0033] In summary, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
