It has richer connotations and extensions, provides an implementation approach for the development of industrial digitalization, networking, and intelligence, greatly improves industrial manufacturing efficiency, and liberates the labor force. Generally, direct interaction between an operator and the Industrial Internet is carried out through a display, that is to say, the display is the external control port of the Industrial Internet.

[0003] The industrial environment is complex, harsh, and changeable. Traditional displays are difficult to be applied for a long time. Therefore, special industrial displays are generally used. The industrial displays in the prior art generally consist of a frame body, a display body, and an outer frame. After the display body is placed in the frame body, the frame body is enclosed by the outer frame, and the fixation between the outer frame and the frame body is uniformly carried out by connecting with a plurality of bolts.

[0004] Directly connecting the outer frame and the frame body with a plurality of bolts surely ensures the connection effect. However, in practical applications, we find that there are still certain deficiencies, such as:

[0005] Connecting with a plurality of bolts is very troublesome, time-consuming and laborious to disassemble and assemble a large number of bolts. Summary of the Invention

[0057] After the loading frame assembly and the outer frame assembly of the present application are buckled, the positioning member can move into the limiting groove of the locking member. Then, by moving the locking member, the position of the positioning member in the limiting groove is changed, so that the limiting groove defines the position of the positioning member in the thickness direction of the loading frame assembly. This structure of the present application can fix the loading frame assembly and the outer frame assembly in a way that uses few or no screws, avoiding the trouble of disassembly and assembly caused by fixing the loading frame assembly and the outer frame assembly with a large number of screw connections.

[0058] Please refer to Figures 1 - 3 , according to an embodiment of the present invention, a display module is proposed, which includes a display screen 10, a loading frame assembly 20 and an outer frame assembly 30. Among them, the loading frame assembly 20 includes a positioning member 21 and a loading frame 22, and the loading frame 22 is provided with the positioning member 21; the outer frame assembly 30 is located on one side in the thickness direction of the loading frame assembly 20, and the outer frame assembly 30 includes an outer frame 31 and a locking member 32 having a limiting groove 321. The locking member 32 is slidably arranged on the outer frame 31 along a first direction, and the first direction is the same as the length direction or the width direction of the outer frame 31. The loading frame assembly 20 and the outer frame assembly 30 are buckled together, and the positioning member 21 is located in the limiting groove 321. By moving the locking member 32, the limiting groove 321 can define the position of the positioning member 21 in the thickness direction of the loading frame assembly 20.

[0059] It can be understood that Figure 1 the C direction in Figure 1 is the thickness direction of the loading frame assembly 20, and the first direction is perpendicular to the C direction in Figure 1 that is, the D direction in

[0060] For the convenience of installation and positioning of the display module, a positioning surface can be set on one side of the loading frame 22. After the display module is assembled, the display screen 10 can be arranged in abutment with the positioning surface, and at least a part of the display screen 10 can sink into the loading frame 22. Specifically, a sink 22c surrounding the loading frame 22 can be arranged on the inner side wall of the loading frame 22, and the surface of the sink 22c facing the display module can be used as the positioning surface.

[0061] The display screen 10 can be a liquid crystal screen, an LED screen, etc.

[0062] The shape of the positioning member 21 can be, but is not limited to, cylindrical, square columnar, etc., and no specific limitation is made here.

[0063] In the present application, the number of the positioning member 21 and the limiting groove 321 can be set to one or more. The positioning member 21 can be arranged on one side or opposite sides of the border of the loading frame 22, and the limiting groove 321 can be arranged on one side or opposite sides of the border of the outer frame 31. The number of the limiting grooves 321 is the same as that of the positioning members 21.

[0064] The positioning member 21 can be fixed on the outer side of the frame of the loading frame 22. When the loading frame assembly 20 is buckled with the outer frame assembly 30, the positioning member 21 directly cooperates with the limiting groove 321 of the locking member 32. The positioning member 21 can also be movably arranged inside the frame of the loading frame 22 and can extend out from the outer side of the frame (this structure will be introduced in detail below).

[0065] That the loading frame assembly 20 is buckled with the outer frame assembly 30 means that a part of the loading frame assembly 20 is sleeved on the outer frame assembly 30, that is, the frame of the loading frame assembly 20 is located outside the frame of the outer frame assembly 30.

[0066] Specifically, a sliding groove can be arranged on the outer frame 31, the locking member 32 can be slidably arranged in the sliding groove, and a part of the locking member 32 is exposed outside the outer frame 31, which is convenient for people to contact the locking member 32 for operation.

[0067] That the loading frame assembly 20 is buckled with the outer frame assembly 30 can limit the position of the outer frame assembly 30 relative to the loading frame assembly 20 in the first direction and the second direction, but does not limit the position in the thickness direction of the loading frame assembly 20. The position in the thickness direction of the loading frame assembly 20 can be limited by the cooperation between the limiting groove 321 of the locking member 32 and the positioning member 21, that is, by moving the locking member 32 to change the relative position between the limiting groove 321 and the positioning member 21, and the limiting groove 321 limits the position of the positioning member 21 in the thickness direction of the loading frame assembly 20 to realize the installation of the display module. With this structure of the present application, the usage amount of bolts can be greatly reduced and the disassembly and assembly efficiency can be improved.

[0068] The second direction is Figure 1 the E direction in, and the second direction is perpendicular to both the first direction and the thickness direction of the loading frame assembly 20.

[0069] In some embodiments, please refer to Figure 2 , the limiting groove 321 includes a first groove portion 321a and a second groove portion 321b. The first groove portion 321a and the second groove portion 321b are communicated. The first groove portion 321a extends along the thickness direction of the loading frame assembly 20, and the second groove portion 321b extends along the first direction. When the loading frame 22 is buckled with the outer frame 31, the positioning member 21 moves into the first groove portion 321a, and by moving the locking member 32, the positioning member 21 moves into the second groove portion 321b to limit the position of the loading frame assembly 20 in the thickness direction of the loading frame assembly 20.

[0070] The communication between the first groove portion 321a and the second groove portion 321b can form a structure such as an L-shaped or T-shaped groove. For example, the opening of the first groove portion 321a can be set in a trapezoidal structure, which is convenient for the positioning during installation to enter the first groove portion 321a more smoothly.

[0071] Optionally, an opening corresponding to the positioning member 21 may be provided in the above chute, and the opening is arranged facing the positioning member 21, so that when the loading frame assembly 20 and the outer frame assembly 30 are installed, the positioning member 21 can slide into the limiting groove 321 of the locking member 32 from the opening. The opening may also not be provided, and the notch of the chute is arranged on the side facing the positioning member 21, which can also achieve the positioning member 21 sliding into the limiting groove 321.

[0072] After the loading frame assembly 20 and the outer frame assembly 30 are buckled together, the positioning member 21 enters the limiting groove 321 from the first groove portion 321a. When the loading frame assembly 20 and the outer frame assembly 30 are buckled in place, the positioning member 21 moves to the deepest part of the first groove portion 321a (the position where the first groove portion 321a intersects with the second groove portion 321b). By moving the locking member 32, the relative position between the second groove portion 321b and the positioning member 21 is changed, and the positioning member 21 enters the second groove portion 321b and is not in the first groove portion 321a. The second groove portion 321b extends in the first direction, thereby limiting the position of the positioning member 21 in the thickness direction of the loading frame assembly 20, and further realizing the fixation of the loading frame assembly 20 and the outer frame assembly 30.

[0073] In some embodiments, please refer to Figure 2 , on the frame of the outer frame 31, there is a chute extending in the first direction, and the locking member 32 is slidably arranged in the chute and has a first moving position and a second moving position; when the locking member 32 is in the first moving position, along the thickness direction of the loading frame assembly 20, the positioning member 21 can slide into or out of the first groove portion 321a; when the locking member 32 is in the second moving position, the positioning member 21 is located in the second groove portion 321b, and the locking member 32 is fixedly connected to the outer frame 31 in a detachable manner.

[0074] Specifically, on the side wall of the chute opposite to the moving direction of the locking member 32, there is a slot 311, and on the side of the locking member 32 opposite to the slot 311, there is a plugging protrusion 322. When the locking member 32 is in the second moving position, the plugging protrusion 322 is in plugging fit with the slot 311. In order to further prevent the plugging protrusion 322 of the locking member 32 from disengaging from the slot 311, a screw hole may be provided on the frame, the screw hole penetrates through the slot 311, a screw is provided in the screw hole, and the screw is threadedly connected to the plugging protrusion 322.

[0075] When the locking member 32 is in the second moving position, the positioning member 21 is located in the second groove portion 321b, and the locking member 32 is fixedly connected to the outer frame 31 in a detachable manner, which can more firmly fix the loading frame assembly 20 and the outer frame assembly 30 together.

[0076] In some embodiments, please refer to Figure 3, within the border of the loading frame 22, a first sliding groove 22a and a second sliding groove 22b communicating with the first sliding groove 22a are provided. The first sliding groove 22a extends along a second direction, which is perpendicular to both the first direction and the thickness direction of the loading frame assembly 20. The second sliding groove 22b extends along the thickness direction of the loading frame assembly 20. The positioning member 21 is slidably disposed in the first sliding groove 22a and can extend out a part from the outside of the loading frame 22 along the second direction. The loading frame assembly 20 further includes a driving member 23 and a first elastic member 24. Among them, the driving member 23 is slidably disposed in the second sliding groove 22b and can extend out a part from one side of the loading frame 22 and abut against the display screen 10; the first elastic member 24 is disposed in the first sliding groove 22a, and both ends of the first elastic member 24 abut against the loading frame 22 and the positioning member 21. Under the action of the first elastic member 24, the positioning member 21 is kept in a contracted state; when the loading frame assembly 20 is buckled with the outer frame assembly 30, the outer frame 31 presses the display screen 10 against the outer frame 31 to cause the driving member 23 to contract, and can generate a force acting on the positioning member 21 along the second direction, so that the positioning member 21 extends out.

[0077] The first elastic member 24 can be a compression spring, a spring piece, etc.

[0078] Specifically, two spaced-apart limiting rings can be fixedly provided in the first sliding groove 22a. One end of the second elastic member 63 abuts against the limiting ring away from the second sliding groove 22b, and the other end of the second elastic member 63 abuts against the positioning member 21.

[0079] When the loading frame assembly 20 is buckled with the outer frame assembly 30, the outer frame 31 presses the display screen 10 against the outer frame 31 to cause the driving member 23 to contract and generate a force acting on the positioning member 21 along the second direction. This force can be the force directly acting on the positioning member 21 by the driving member 23, or the force indirectly acting on the positioning member 21. For example, the positioning member 21 is in direct contact with the driving member 23, and the force generated by the movement of the driving member 23 acting on the positioning member 21. It can also be that the positioning member 21 is not in direct contact with the driving member 23. For example, the first sliding groove 22a and the second sliding groove 22b form a closed chamber, and the driving member 23 contracts to move the positioning member 21 by means of compressed air (which will be introduced in detail below).

[0080] The positioning member 21 can be retracted into the frame of the loading frame 22. During assembly, the display screen 10 is pressed against the loading frame 22 by the outer frame assembly 30. The contact between the display screen 10 and the driving member 23 also causes the driving member 23 to contract, generating a force in the second direction on the positioning member 21 to extend it out from the outside of the frame of the loading frame 22. Compared with the structure where the positioning member 21 is directly fixed to the outside of the frame of the loading frame 22, this structure can avoid the problem of the positioning member 21 being easily broken when fixed to the outside of the loading frame 22 during transportation before assembly. At the same time, under the elastic force of the first elastic member 24, a force in the thickness direction of the loading frame assembly 20 is generated on the driving member 23 and acts on the display screen 10, which can more firmly limit the display screen 10 between the loading frame assembly 20 and the outer frame assembly 30, prevent the display screen 10 from shaking after the display screen 10 module is assembled, and further reduce the risk of the display screen 10 being broken. The positioning member 21 can be retracted into the first sliding groove 22a, which also facilitates the transportation of the loading frame assembly 20.

[0081] The driving member 23 includes a first piston portion 231 and a contact portion 232 connected to the first piston portion 231. The first piston portion 231 is slidably disposed in the second sliding groove 22b and is in sealing cooperation with the side wall of the second sliding groove 22b. The contact portion 232 can extend out a part from one side of the loading frame 22 and contact the display screen. The positioning member includes a second piston portion 212 and a positioning portion 211 connected to the second piston portion 212. The second piston portion 212 is slidably disposed in the first sliding groove 22a and is in sealing cooperation with the side wall of the first sliding groove 22a. The part of the first piston portion 231 blocking the second sliding groove 22b and the part of the second piston portion 212 blocking the first sliding groove 22a form a closed space. The positioning portion 211 can extend out a part from the outside of the loading frame 22 in the second direction and can be in limiting cooperation with the limiting groove 321. When the contact portion 232 is in the extended state, the positioning portion 211 is located in the first sliding groove 22a. When the contact portion 232 is located in the second sliding groove 22b, the positioning portion 211 is in the extended state.

[0082] The first piston portion 231 blocks the second sliding groove 22b, and the second piston blocks the first sliding groove 22a, forming a closed space in the first sliding groove 22a and the second sliding groove 22b. When the driving member 23 moves and contracts, compressed air generates air pressure in the closed space. The air pressure acts on the second piston portion 212 to push the positioning member to move in the second direction outward from the loading frame 22 and extend out from the frame of the loading frame 22. Through this structure, the positioning member can be automatically extended and cooperate with the limiting groove 321 during the assembly process. Then, by moving the locking member 32, the relative position of the outer frame assembly 30 and the loading frame 22 assembly in the thickness direction of the loading frame 22 assembly is limited. This not only facilitates transportation but also simplifies the assembly process, avoiding the time-consuming, laborious, and thread-sliding problems of using a large number of screws for assembly.

[0083] In some embodiments, please refer to Figure 3 A mating surface (not shown in the figure) is formed on the side of the positioning member 21 facing the second slide groove 22b. The mating surface is any one of a wedge surface, an arc surface or a spherical surface. At least part of the mating surface is located in the second slide groove 22b. When the driving member 23 contracts, it can squeeze the mating surface, so that the positioning member 21 extends partially from one side of the loading frame 22 along the second direction.

[0084] The driving member 23 may be a columnar structure, specifically, but not limited to, a square column, a circular column, etc.

[0085] When the driving member 23 contracts, the outer surface of the driving member 23 can press the matching surface, and the component of the pressing force acts on the positioning member 21 along the second direction to drive the positioning member 21 to move so that the positioning member 21 extends from the outer side of the frame of the loading frame 22.

[0086] In some embodiments, please refer to Figures 4 - 6 The display module further includes a cooling pipe 40, a valve 50, and an adjustment mechanism 60. The cooling pipe 40 is mounted on the loading frame 22 and has an inlet and an outlet on opposite sides of the loading frame 22. Both the inlet and the outlet are provided with valves 50. The adjustment mechanism 60 is drivingly connected to the valve stem of the valve 50 and is mounted on the loading frame 22. The display screen 10 is positioned against the adjustment mechanism 60. Under the pressure of the display screen 10, the adjustment mechanism 60 can drive the valve stem to rotate, thereby opening the valve 50. When the display screen 10 contacts the adjustment mechanism 60, the adjustment mechanism 60 can drive the valve stem to rotate, thereby closing the valve 50.

[0087] The cooling pipe 40 may be, but is not limited to, a serpentine pipe, a spiral coil, or the like.

[0088] The valve 50 is a manual valve.

[0089] The cooling tube 40 is located on a side of the device frame facing away from the display screen 10 .

[0090] The cooling pipe 40 can be used for heat dissipation of large display devices, such as indoor and outdoor advertising screens.

[0091] Before assembly, the adjustment mechanism 60 maintains the valve 50 closed, preventing foreign matter from entering the cooling pipe 40 and causing blockage during transportation. Currently, the inlet and outlet are threadedly connected to the cooling pipe 40 using plugs. However, this application automatically opens the valve 50 after assembly, connecting it to the external cooling system. During transportation before assembly, the valve 50 on the loading frame assembly 20 is normally closed, preventing foreign matter from entering and eliminating the hassle of removing and installing the plugs.

[0092] During the assembly process, the display screen 10 presses on the adjustment mechanism 60 to generate a driving force, causing the position of the valve stem to change, further causing the valve 50 to be in an open state, enabling the inlet and outlet of the cooling pipe 40 to be connected to an external cooling system. The external cooling system supplies a cooling medium to the cooling pipe 40, and the cooling medium can be, but is not limited to, water. The specific structure of the cooling system is not the focus of protection of this application and will not be described in detail here.

[0093] In some embodiments, please refer to Figure 5 and Figure 6 , the loading frame 22 is provided with a guiding groove extending in the thickness direction of the loading frame assembly 20. The adjustment mechanism 60 includes a first gear 61, a rack 62, and a second elastic member 63. Among them, the first gear 61 is fixedly arranged on the valve stem; the rack 62 is slidably arranged in the guiding groove along the thickness direction of the loading frame assembly 20, and the rack 62 is used to drive the first gear 61 to rotate; the second elastic member 63 is arranged in the guiding groove, and along the thickness direction of the loading frame assembly 20, both ends of the second elastic member 63 abut against one end of the rack 62 and the loading frame 22, enabling the rack 62 to protrude from one side of the loading frame 22 under the action of elastic force; when the rack 62 protrudes from one side of the loading frame 22, the valve 50 is in a closed state; when the display screen 10 presses the rack 62 into the guiding groove, the valve 50 is in an open state.

[0094] The first gear 61 can be, but is not limited to, an external cylindrical gear.

[0095] The second elastic member 63 can be, but is not limited to, a compression spring, a spring sheet, a disc spring, etc.

[0096] The guiding groove can be a non-through groove, the second elastic member 63 can be arranged in the guiding groove, and the rack 62 is arranged in the guiding groove and abuts against the second elastic member �3.

[0097] The rack 62 is used to drive the first gear 61 to rotate. It can be that the rack 62 directly meshes with the first gear 61 to drive the first gear 61 to rotate, or it can be that a plurality of gears are arranged between the rack 62 and the first gear 61 to form a transmission mechanism to drive the first gear 61 to rotate.

[0098] Before the display module is assembled, the rack 62 protrudes from the guiding groove under the action of the second elastic member 63 and drives the first gear 61 to rotate to make the valve 50 in a closed state, which can ensure that foreign objects do not enter the cooling pipe 40 during transportation.

[0099] After the display module is assembled, the display screen 10 presses on the end of the rack 62, causing the rack 62 to contract into the guiding groove. At this time, the rack 62 drives the first gear 61 to rotate, opening the valve 50.

[0100] In some embodiments, please refer to Figure 5 and Figure 6, the adjusting mechanism 60 further includes a second gear 64 and a third gear 65. Among them, the second gear 64 is rotatably arranged on the loading frame 22, and the first gear 61 and the second gear 64 mesh with each other; the third gear 65 is rotatably arranged on the loading frame 22 and fixedly connected to the second gear 64, and is coaxially arranged with the second gear 64, and the third gear 65 meshes with the rack 62.

[0101] Both the first gear 61 and the second gear 64 can be bevel gears or external cylindrical gears.

[0102] When the valve stem of the valve 50 is arranged along the thickness direction of the loading frame assembly 20, both the first gear 61 and the second gear 64 are bevel gears, and the transmission of the rack 62 along the thickness direction of the loading frame assembly 20 can be converted into the rotation of the valve stem.

[0103] When the valve stem of the invention is arranged perpendicular to the thickness direction of the loading frame assembly 20, both the first gear 61 and the second gear 64 are external cylindrical gears. At this time, the second gear 64 and the third gear 65 can also be omitted, and the rack 62 directly meshes with the first gear 61 to drive the opening and closing of the valve 50.

[0104] In some embodiments, please refer to Figure 1 , the outer frame assembly 30 further includes a glass plate 33 provided on the outer frame 31, and the glass plate 33 is located on the side of the display screen 10 away from the loading frame 22.

[0105] The glass plate 33 not only does not block the display screen 10, but also can effectively protect it, preventing the harsh environment in the industrial workshop from damaging the display screen 10.

[0106] In some embodiments, the outer frame assembly 30 further includes a sealing ring provided on the inner peripheral wall of the outer frame 31, and the sealing ring is in abutment with the display screen 10 and the glass plate 33.

[0107] The sealing ring can be, but is not limited to, a silica gel sealing ring or a rubber sealing ring.

[0108] The sealing ring can be pressed on the four peripheral edges of the display screen 10, which can not only effectively ensure the sealing performance, but also play a certain buffering role for the display screen 10. Even if there is a large amplitude of shaking, the display screen 10 can be effectively prevented from being damaged through the sealing ring.

[0109] According to the embodiment of the present invention, a display device is proposed, including the above display module.

[0110] The display device may be, but is not limited to, the LED electronic display screen 10, the liquid crystal display device, the advertising screen device, etc. As described above, only the preferred specific embodiments of the present invention are given, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
