Detailed Description
For a better understanding of the features and technical solutions of the present invention, as well as the specific objects and functions attained by the present invention, reference is made to the accompanying drawings and detailed description of the invention.
Referring to fig. 1-13: an LCD (liquid crystal display) passenger guide screen convenient to disassemble, assemble and maintain comprises an LCD screen 1, an installation seat 2, an installation structure 3, a fixed structure 4 and a driving structure 5, wherein two first handles 1a are fixedly installed on the LCD screen 1; two installation bases 2 are arranged, and guide rails 2a are fixedly arranged on the installation bases 2; the number of the mounting structures 3 is two, the two mounting structures 3 are respectively positioned on two sides of the LCD screen 1, and each mounting structure 3 comprises a mounting part 3a and a second handle 3 b; the mounting part 3a is fixedly mounted on the LCD screen 1, and the mounting part 3a is in sliding fit with the guide rail 2 a; the second handle 3b is fixedly mounted on the mounting portion 3 a.
According to the invention, the function of quickly dismounting the LCD screen 1 is realized through the mounting seat 2 and the mounting structure 3, the effect of realizing dismounting through the butt joint of the slide rails is achieved, the effect is quick and effective, the condition that the traditional passenger guiding screen needs to be quickly dismounted through the matching of multi-directional bolts and springs is avoided, and the problem that the screen cannot be quickly dismounted by a single person is solved. When an operator installs the LCD screen 1, the operator firstly grasps the LCD screen 1 through the first handle 1a and moves the LCD screen 1 to an installation place, then fixes the two installation bases 2 to the driving structure 5 through bolts according to a specific interval, the installation is convenient because the installation bases 2 are small in size, after the installation of the installation bases 2 is completed, the operator grasps the LCD screen 1 through the second handle 3b and moves the LCD screen 1 to the installation bases 2, the installation portions 3a are aligned with the guide rails 2a, the installation portions 3a on the two sides respectively slide into the two guide rails 2a to support and fix the LCD screen 1, and the LCD screen 1 slides into the grooves under the action of gravity by arranging the grooves on the guide rails 2a, so that the situation that the LCD screen 1 automatically slides along the guide rails 2a under the action of external force after the installation is completed is avoided; when the LCD screen 1 is detached, an operator lifts the LCD screen 1 upwards to slide out of the groove in the guide rail 2a, then slides along the guide rail 2a to separate the LCD screen from the mounting seat 2, carries out maintenance on the LCD screen, and after the maintenance is finished, the mounting part 3a slides into the groove in the guide rail 2a according to the parts to mount and fix the LCD screen.
Further, with reference to fig. 1, 3 and 5: the mounting structure 3 further comprises a positioning assembly 3c, the positioning assembly 3c comprises a positioning bolt 3c2 and a first elastic piece 3c 3; the mounting seat 2 is provided with a positioning hole 3c 1; the positioning bolt 3c2 is slidably mounted on the mounting part 3a, and the positioning bolt 3c2 is in threaded connection with the positioning hole 3c 1; both ends of the first elastic piece 3c3 are fixedly connected with the positioning bolt 3c2 and the mounting part 3a, respectively.
According to the invention, the function of improving the matching accuracy of the installation part 3a and the guide rail 2a is realized through the positioning hole 3c1, the positioning bolt 3c2 and the first elastic piece 3c3, and the effect of further enhancing the connection strength of the LCD screen 1 and the installation seat 2 is achieved; if an operator installs the LCD screen 1, the installation part 3a does not completely slide to the end surface of the guide rail 2a, which may cause the situation that the installation part shakes or even slides off after the installation is completed; an operator slides the mounting part 3a of the LCD screen 1 into the guide rail 2a, pushes the mounting part 3a to the edge of the guide rail 2a, enables the mounting part 3a to be tightly abutted against the guide rail 2a, then presses the positioning bolt 3c2, the positioning bolt 3c2 overcomes the elastic force of the first elastic piece 3c3 to be in contact with the positioning hole 3c1, then rotates the positioning hole 3c1 to be in threaded connection with the positioning hole 3c1, if the LCD screen 1 is not mounted in place, the axis of the positioning bolt 3c2 deviates from the axis of the positioning hole 3c1, and cannot be in threaded connection; through the cooperation of locating hole 3c1 and positioning bolt 3c2, avoided the too big condition of LCD screen 1 mounted position error.
Further, referring to fig. 1, 3-8: the fixed structure 4 comprises a first connection assembly 4a, the first connection assembly 4a comprising a first threaded sleeve 4a1, a first bushing 4a2 and a first bolt 4a 3; the first thread bush 4a1 is fixedly mounted on the mounting portion 3 a; the first shaft sleeve 4a2 is rotatably mounted on the mounting part 3 a; the first bolt 4a3 is in axial sliding fit with the first shaft sleeve 4a2, and the first bolt 4a3 is in threaded connection with the first threaded sleeve 4a 1; the mounting base 2 is provided with a first threaded hole 4a4 engaged with the first bolt 4a 3.
According to the invention, the function of further enhancing the connection strength between the mounting seat 2 and the mounting part 3a is realized through the first threaded sleeve 4a1, the first shaft sleeve 4a2 and the first bolt 4a3, the situation that the mounting seat falls off due to the influence of external force after being mounted is avoided, and the effect of enhancing the safety is achieved; in order to facilitate the assembly and disassembly of the LCD screen 1 by an operator, the number of thread turns of the positioning bolt 3c2 is small, so that the first connecting assembly 4a is arranged for fixedly connecting the mounting seat 2 and the mounting part 3a, the stress of the positioning bolt 3c2 is small, and the positioning bolt only plays a role in positioning and does not bear supporting force; after the operator slides the mounting portion 3a into the guide rail 2a, the positioning assembly 3c positions the mounting portion, and then the first bushing 4a2 is rotated, the first bushing 4a2 drives the first bolt 4a3 to rotate, and since the first threaded hole 4a4 is in threaded connection with the first bolt 4a3, the first bolt 4a3 moves close to the mounting seat 2 along the axial direction of the first bushing 4a2 while rotating, and as the first bushing 4a2 continues to rotate, the first bolt 4a3 contacts and is in threaded connection with the first threaded hole 4a4, so that the mounting seat 2 and the mounting portion 3a are fixedly connected through the first bolt 4a 3.
Further, referring to fig. 1 and 3: the mounting structure 3 further comprises a first rotation shaft 4b and a cover 4 c; the first rotating shaft 4b is rotatably mounted on the LCD panel 1; the cover 4c is fitted over the first rotating shaft 4 b.
