[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Reference Figure 1-Figure 3 A 3D printer screen fixing component comprises a printer housing 1 and a mounting frame 5, wherein a screen mounting groove 3 for positioning a screen is provided on the printer housing 1, two plug-in blocks 2 are fixedly installed on the upper end surface of the printer housing 1, and two plug-in grooves 13 cooperating with the plug-in blocks 2 are provided on the lower end surface of the mounting frame 5, and two fixing components for fixing the plug-in blocks 2 are symmetrically arranged on the mounting frame 5, wherein the fixing component comprises an L-shaped slide groove 10 provided in the plug-in groove 13, a rectangular slide groove 14 is provided at the upper end of the L-shaped slide groove 10, a latch 11 is slidably connected inside the L-shaped slide groove 10, and a side of the latch 11 away from the plug-in groove 13 is elastically connected to the L-shaped slide groove 10 through two sets of second springs 9, and a toggle block 12 is fixedly installed on the upper end of the latch 11, and the toggle block 12 is located in the rectangular slide groove 14;

[0024] The latch 11 is L-shaped, and the lower side of one end extending into the insertion slot 13 is a sloped structure, and the upper side of one end of the toggle block 12 facing the pressing block 6 is a sloped structure;

[0025] The plug block 2 is provided with a socket 4 adapted to the plug pin 11;

[0026] Two pressing components for releasing the fixing restriction of the plug-in block 2 are symmetrically arranged on the mounting frame 5. The fixing component includes a through hole opened on the upper side of the mounting frame 5. A pressing block 6 is arranged inside the through hole. The pressing block 6 is elastically connected to the through hole through a first spring 8. The through hole is connected to the rectangular slide groove 14.

[0027] The left and right sides of the installation frame 5 are provided with grooves 7, and the corners where the inner top of the groove 7 intersects with the side of the installation frame 5 are rounded. The groove 7 is convenient for lifting the installation frame 5, and the rounded corners avoid scratching the user's hands.

[0028] Working principle:

[0029] During installation, the screen is placed in the screen installation slot 3, and then the plug-in block 2 is inserted into the plug-in slot 13. Due to the inclined design of the latch 11, the latch 11 is squeezed and contracted when in contact with the plug-in block 2. At this time, the second spring 9 is in a contracted state. When the latch 11 is aligned with the socket 4, the latch 11 is inserted into the socket 4 under the action of the second spring 9, so as to fix the plug-in block 2, thereby completing the fixing of the installation frame 5 and fixing the screen;

[0030] When disassembling, insert four fingers into the groove 7, put the thumb on the pressing block 6 and press it. The pressing block 6 moves down to squeeze the toggle block 12, so that the toggle block 12 drives the latch 11 to contract, and the latch 11 falls off the socket 4, and then lift the installation frame 5 to complete the disassembly.

[0031] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
