[0030] In one possible implementation,

[0031] Please refer to Figure 1-Figure 7The embodiment of the utility model provides an LCD whole machine fixing structure, including an upper shell 1, a lower shell 2 and an LCD module 3. The upper shell 1 and the lower shell 2 can be locked by screws or buckles 101. The four corners of the lower shell 2 are fixedly connected with bosses 8. The lower shell 2 and the bosses 8 can be integrally formed. The four corners of the LCD module 3 are fixedly connected with columns 4. The outer surface of the column 4 is sleeved with an elastic member 5. A first through hole 6 corresponding to the column 4 is opened in the boss 8. A groove 7 corresponding to the elastic member 5 is opened on the side of the first through hole 6 close to the column 4. After the upper shell 1 and the lower shell 2 are fixed, the elastic member 5 is located inside the groove 7.

[0032] The above-mentioned LCD whole machine fixing structure is used to assemble the backlight panel 301, the PCB driver board 302, the TFT screen 303 and the connector 305 together to form an LCD module 3, and then the elastic member 5 made of rubber material is sleeved on the column 4, and then the column 4 is inserted into the boss 8 on the lower shell 2. At this time, the column 4 is located in the first through hole 6, and the elastic member 5 will enter the groove 7, and then the upper shell 1 and the lower shell 2 are installed. At this time, the buckle 101 will be snapped into the slot 201, and the elastic member 5 will be slightly compressed. At this time, the LCD module 3 presses the foam 9 and the upper shell 1 through the restoring force of the elastic member 5. In this way, the entire LCD module 3 is assembled without using any glue or double-sided tape. If there is a problem and rework is required, it can be disassembled at will without damaging the LCD module 3. Disassembly and rework are particularly convenient.

[0033] In this embodiment, the upper shell 1 and the lower shell 2 are both made of plastic material. A plurality of buckles 101 are fixedly connected to one side of the upper shell 1 close to the lower shell 2 , and a slot 201 corresponding to the buckle 101 is provided on one side of the lower shell 2 close to the upper shell 1 .

[0034] The upper shell 1 and the lower shell 2 made of plastic material are easy to process and light in weight. The buckle 101 is integrally formed with the upper shell 1, and the slot 201 is integrally formed with the lower shell 2. When the upper shell 1 and the lower shell 2 are installed, the buckle 101 made of plastic will be compressed and shrink inward. When the positions of the buckle 101 and the slot 201 correspond, the buckle 101 will be snapped into the slot 201 under the action of elasticity, thereby completing the fixation of the upper shell 1 and the lower shell 2. At the same time, the upper shell 1 and the lower shell 2 can also be locked by screws.

[0035] In this embodiment, the LCD module 3 includes a backlight panel 301, a PCB driver board 302 and a TFT screen 303. A mounting groove 304 is opened in the middle of the left side of the backlight panel 301. The TFT screen 303 is fixedly connected inside the mounting groove 304. A connector 305 is installed on the right side of the PCB driver board 302. The connector 305 is electrically connected to the LCD module 3 through a wire.

[0036] In this configuration, the TFT screen 303 is first fixedly connected inside the mounting groove 304, the surface of the TFT screen 303 is flush with the surface of the backlight panel 301, and the connector 305 is electrically connected to the LCD module 3 through a wire. The LCD module 3 can communicate with the outside through the connector to display different contents.

[0037] In this embodiment, foam 9 is installed between the LCD module 3 and the inner wall of the upper shell 1, and the foam 9 has elasticity.

[0038] After the upper shell 1 and the lower shell 2 are locked by screws or buckles 101, the foam 9 will be slightly compressed, and the foam 9 will be in close contact with the upper shell 1 and the LCD module 3 on the left and right sides through a slight elastic force, thereby preventing dust from entering and increasing the service life of the LCD device.

[0039] In this embodiment, the elastic member 5 is a rubber sleeve made of rubber material, and the rubber sleeve is sleeved on the outer surface of the column 4 .

[0040] The rubber sleeve made of rubber material is low in cost and easy to process. After the elastic member 5 made of rubber material is sleeved on the column 4, the upper shell 1 and the lower shell 2 are locked by screws or buckles 101. During this process, the elastic member 5 will also be slightly compressed, and a reaction force will be applied to the LCD module 3 through the elastic force, so that the foam 9 can better contact with the upper shell 1 and the LCD module 3 on the left and right sides. At the same time, the LCD module 3 can be firmly installed inside the upper shell 1 and the lower shell 2 to avoid loosening.

[0041] In this embodiment, a second through hole 102 is opened in the middle of the left side of the upper shell 1 , and the diameter of the second through hole 102 is smaller than the diameter of the LCD module 3 .

[0042] After the upper shell 1 and the lower shell 2 are locked by screws or buckles 101 in this way, the LCD module 3 can be exposed from the second through hole 102, so that the LCD module 3 can better display content.

[0043] In this embodiment, an internal thread is provided in the groove 7, and an adjustment sleeve 701 is connected to the internal thread of the internal thread. The adjustment sleeve 701 is a cylindrical structure and the interior thereof is equal in size to the elastic member 5. A hexagonal head 702 is provided on the left side of the adjustment sleeve 701.

[0044] After long-term use, the elastic force of the elastic member 5 will be reduced. When the LCD machine is disassembled and then installed again, the foam 9 may not be in good contact with the upper shell 1 and the LCD module 3 on the left and right sides. At this time, after disassembling the LCD module 3, we use a tool to rotate the hexagonal head 702 and the adjustment sleeve 701. Since the adjustment sleeve 701 is threadedly connected to the internal thread in the groove 7, the adjustment sleeve 701 can move to the left during the rotation. At this time, after we install the upper shell 1 and the lower shell 2 again, the elastic member 5 will be compressed, so that the foam 9 is in close contact with the upper shell 1 and the LCD module 3 on the left and right sides through the restoring force of the elastic member 5, so as to prevent dust from entering and improve the service life of the LCD machine.

[0045] In this embodiment, an installation gap 11 is provided between the backlight panel 301 and the upper shell 1 , and a positioning component 10 is provided in the installation gap 11 . The positioning component 10 is used to assist in limiting the backlight panel 301 .

[0046] With this arrangement, when the entire LCD device is disassembled, the positioning assembly 10 is used to assist in limiting the backlight panel 301. At this time, the LCD module 3 is connected to the lower shell 2 through the positioning assembly 10 to prevent the LCD module 3 from falling out due to sudden opening of the upper shell 1, and the disassembly is safer.

[0047] The positioning assembly 10 includes a rotating shaft 1001 rotatably connected to the lower shell 2, a positioning rod 1002 is fixedly connected to the outer surface of the rotating shaft 1001, a positioning block 1003 is fixedly connected to one side of the positioning rod 1002, a limiting groove 1004 is provided on the side of the backlight panel 301, a positioning groove corresponding to the positioning block 1003 is provided on the inner wall of the limiting groove 1004, and a handle 1005 is fixedly connected to the other end of the rotating shaft 1001, and an anti-slip pattern is provided on the outer surface of the handle 1005.

[0048] In this way, when the LCD machine is disassembled, the positioning component 10 is used to assist in limiting the backlight plate 301. At this time, the LCD module 3 is pressed to compress the elastic member 5. At this time, the positioning block 1003 is disengaged from the positioning groove, and then the handle 1005 is turned to drive the shaft 1001 to rotate. During the rotation process, the shaft 1001 can drive the positioning rod 1002 to disengage from the limiting groove 1004. At this time, the LCD module 3 can be safely taken out. During installation, the column 4 is inserted into the boss 8 on the lower shell 2. At this time, the column 4 is located in the first through hole 6, and the elastic member 5 will enter the groove 7. Then the LCD module 3 is pressed to compress the elastic member 5. Then the handle 1005 is turned to drive the shaft 1001 to rotate. During the rotation process, the shaft 1001 can drive the positioning rod 1002 to rotate to the limiting groove 1004. Then the LCD module 3 is released. At this time, the positioning block 1003 is stuck in the positioning groove, so that the LCD module 3 is connected to the lower shell 2.

[0049] The technical solution provided by the utility model is that the LCD whole machine fixing structure is used as follows Figure 1-7 As shown, when in use, the backlight plate 301, the PCB driver board 302, the TFT screen 303 and the connector 305 are assembled together to form the LCD module 3, and then the elastic member 5 made of rubber material is sleeved on the column 4, and then the column 4 is inserted into the boss 8 on the lower shell 2. At this time, the column 4 is located in the first through hole 6, and the elastic member 5 will enter the groove 7, and then the upper shell 1 and the lower shell 2 are installed. At this time, the buckle 101 will be snapped into the slot 201, and the elastic member 5 will be slightly compressed. At this time, the LCD module 3 presses the foam 9 and the upper shell 1 through the restoring force of the elastic member 5. In this way, the entire LCD module 3 is assembled without using any glue or double-sided tape. If there is a problem and rework is required, it can be disassembled at will without damaging the LCD module 3. Disassembly and rework are particularly convenient.

[0050] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
