In view of the above problems, the present application provides a display terminal 100, as shown in fig. 1 to 5, including a display screen assembly 110 and a chassis 120, the display screen assembly 110 being fixed to the chassis 120; the rack 120 includes a base 123 and a supporting frame 121, a first end of the supporting frame 121 is connected to the base 123, a second end of the supporting frame 121 extends along a side away from the base 123, a second end of the supporting frame 121 is provided with a first quick release locking mechanism, and the first quick release locking mechanism is configured to be connectable to a back side of the display screen assembly 110 and limit displacement of the display screen assembly 110 in a horizontal direction; a second quick release locking mechanism is disposed on the base 123, and is configured to be connectable to the bottom of the display screen assembly 110 and limit the displacement of the display screen assembly 110 in the vertical direction.

It should be noted that the display screen assembly 110 is fixed on the base 123 through the supporting frame 121, for example, may be fixed by screws. The locking piece that the convenience that above-mentioned quick detach locking mechanical system indicated was dismantled, this locking piece can be locking modes such as joint, need not to demolish the screw one by one. The supporting frame 121 and the display screen assembly 110 are locked by a first quick release locking mechanism to limit the displacement of the display screen assembly 110 in the horizontal direction; and the display screen assembly 110 is locked with the base 123 through a second quick release locking mechanism to limit the displacement of the display screen assembly 110 in the vertical direction. Because the display screen assembly 110 is easier to disassemble by using the quick-release locking mechanism, the display screen assembly 110 is fixed by the first quick-release locking mechanism and the second quick-release locking mechanism, the operation of disassembling a plurality of screws and other fixing parts on the display screen of the display terminal 100 is omitted, the disassembling efficiency of the display screen assembly 110 is improved, and the display screen assembly 110 can be conveniently converted into different installation modes.

Illustratively, as shown in fig. 6, the first quick release locking mechanism includes a latch 122, the latch 122 includes a first lock 1221 and a second lock 1222 that are relatively rotatable, the first lock 1221 is disposed on the supporting frame 121, the second lock 1222 is disposed on the display screen assembly 110, and when the first lock 1221 and the second lock 1222 are rotated to different relative angles, the first lock 1221 is locked or unlocked with each other, so that the display screen assembly 110 is connected to the supporting frame 121, or is disconnected from the supporting frame 121.

Specifically, the other end of the supporting frame 121 is detachably fixed to the supporting back plate 112 through a latch 122. Generally, the support back plate 112 is provided with a frame, and mounting holes are correspondingly formed in the wall surfaces of the frame and the support plate 121, and the snap lock 122 can be, for example, a snap lock, and the snap lock includes a first lock 1221 and a second lock 1222 that can be locked with or unlocked from each other, and the first lock 1221 and the second lock 1222 are respectively provided in the mounting holes of the support plate 121 and the frame, so as to detachably fix the support plate 121 to the support back plate 112.

In order to achieve a more stable support, the support frame 121 may be a diagonal support structure, i.e., the main body of the support frame forms an angle with the display screen assembly 110.

Through the fixing of support frame 121, make display screen subassembly 110 be fixed in on base 123, and because support frame 121 and support backplate 112 are fixed through the quick lock of spring, direct when dismantling display screen subassembly 110 take off the hasp can, need not manual one by one and demolish the screw, the dismantlement of display screen subassembly 110 of being convenient for.

Optionally, as shown in fig. 7 to 8, the second quick release locking mechanism includes an eccentric hook lock 140 and a fixing pin 141, the eccentric hook lock 140 is disposed on a side of the display screen assembly 110 opposite to the display surface, the fixing pin 141 is disposed at a position of the base 123 corresponding to the eccentric hook lock 140, and the eccentric hook lock 140 is connected to the fixing pin 141 in a matching manner, so that the display screen assembly 110 is fixed to the base 123 in the vertical direction.

Through setting up eccentric hook lock 140, can make the fixed of display screen subassembly 110 and base 123 more reliable, and because eccentric hook lock 140 can break away from with the fixed pin 141 through the key rotation and collude even, it is comparatively convenient when the screen body is dismantled.

In an alternative embodiment, as shown in fig. 9-10, a guide plate 124 is further disposed on the base 123, the guide plate 124 is disposed on a surface of the base 123 in a protruding manner, a sliding groove 125 is disposed on a wall surface of the display screen assembly 110 corresponding to an extending direction of the guide plate 124, and the sliding groove 125 is used for inserting the guide plate 124 to position the display screen assembly 110 on the base 123.

In this embodiment, the guide plate 124 and the sliding groove 125 are fixed in a matching manner, so that the fixing position of the display screen assembly 110 on the base 123 can be conveniently located, the display screen assembly 110 can be conveniently and rapidly aligned to the fixing member including the frame member 130, the supporting frame 121 and the fixing pin 141, and the display screen assembly 110 can be rapidly installed.

Alternatively, as shown in fig. 9-10, the guide plate 124 is disposed on the surface of the base 123 and corresponds to the sidewall of the display screen assembly 110, at least a part of the surface of the guide plate 124 is coplanar with the sidewall of the display screen assembly 110, and the sliding groove 125 is disposed on the sidewall of both sides of the display screen assembly 110.

Generally, the back of the display screen assembly 110 is provided with a control box 190 for controlling the display screen assembly 110, and the guide plate 124 is arranged on the side wall of the display screen assembly 110, so that the front and back regions of the display screen assembly 110 do not need to be occupied, and the board space of the display screen assembly 110 can be reasonably utilized. This prevents the guide plate 124 and the slide groove 125 from interfering with these components. It is understood that the length of the chute 125 should be set according to the height of the guide plate 124.

To facilitate insertion of the guide plate 124 into the slide groove 125, it is possible to provide the guide plate 124 with a width smaller than the width of the side wall of the display screen assembly 110, as shown in fig. 9-10. Thus, when the sliding groove 125 is formed in the side wall of the display screen assembly 110, the occupied space of the sliding groove 125 can be within the width range of the side wall of the display screen assembly 110, so that the increase of the width of the side wall of the display screen assembly 110 due to the fact that the sliding groove 125 protrudes out of the side wall of the display screen assembly 110 is avoided, and the frame member 130 can be conveniently installed and fixed.
