DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] To illustrate this embodiment, a brief introduction is now made to the connection method between the LCD display screen and the background in the prior art. It is a common connection method to directly connect the LCD display screen and the background with a connecting wire. This connection method has the advantages of simple and fast single operation in operation, but there is a disadvantage that the number of connecting wires increases with the number of LCD display screens, so that after splicing a plurality of LCD display screens, multiple connecting wire connection operations need to be performed, resulting in the overall operation being cumbersome, and multiple connecting wires are scattered and stacked, which is not beautiful; in order to improve the convenience of the connection operation of the connecting wires after splicing multiple LCD display screens and the aesthetics after connection, there is a multi-LCD display screen splicing method that uses a female connector and a male telescopic connector to cooperate to connect two adjacent LCD display screens, so that the first LCD display screen or the tail LCD display screen of the LCD display screen group formed after splicing is connected to the background through a connecting wire. This splicing method integrates the connecting wire into the LCD display screen, effectively improving the aesthetics between the LCD display screen and the background, but the male telescopic connector must still be manually connected to the female connector end, and there is still room for improvement in further improving the convenience of splicing.

[0030] See also Figures 1 to 9 A spliced ​​LCD display screen with a waterproof mechanism comprises a mounting frame 100 and an LCD display screen module 200; the mounting frame 100 comprises a frame body 1 and a partition 2, the partition 2 is fixedly arranged in the frame body 1, the partition 2 divides the inner cavity of the frame body 1 into a first mounting cavity 101 and a second mounting cavity 102, the LCD display screen module 200 is installed in the first mounting cavity 101; two opposite ends of the frame body 1 are respectively provided with a mounting opening 103 connected to the second mounting cavity 102, the two mounting openings 103 are respectively installed with a female end seat 3 and a male end seat 4, the female end seat 3 is connected to the frame body by screws 1 is fixedly connected, and the male end seat 4 can slide between the second installation cavity 102 and the installation opening 103; the female end seat 3 and the male end seat 4 are respectively installed with the female end 31 and the male end 41 of the connector; the male end seat 4 is embedded with an electric connection adapter 42 and an electric connection seat 43, one end of the electric connection adapter 42 is electrically connected to the male end 41 of the connector, and the other end of the electric connection adapter 42 is electrically connected to the electric connection seat 43 through a plate-type thermal fuse 44; the female end 31 of the connector and the electric connection seat 43 are both electrically connected to the spliced ​​LCD display screen module 200 through wires; and a through hole for the wire to pass through is provided on the partition 2. When at least two spliced ​​LCD screens are spliced ​​together, the matching female connector ends 31 and male connector ends 41 on the two adjacent spliced ​​LCD screens are brought close to each other, and after the two adjacent frames 1 are abutted against each other, the female connector ends 31 and the male connector ends 41 are butted against each other; after at least two spliced ​​LCD screens are spliced ​​together, the exposed female connector ends 31 are connected to the backstage through a connecting line having a male connector end 41, so as to reduce the number of connecting lines between the spliced ​​LCD screen and the backstage to one.

[0031] To facilitate the docking of the matching female connector end 31 and male connector end 41 on two adjacent LCD screens, this embodiment provides a docking method that can utilize the relative movement of two LCD screens to achieve automatic docking of the female connector end 31 and male connector end 41. The details are as follows.

[0032] A flip-type connecting component and a telescopic connecting component are installed in the second installation cavity 102; a part of the flip-type connecting component is flipped 180 degrees and stuck on the frame 1 and extends outside the frame 1; a fuse detachment component is also connected to the power socket 43, one end of the fuse detachment component is connected to the male end seat 4 and the extended end of the telescopic connecting component, and the other end of the fuse detachment component is connected to the telescopic connecting component; in the process of bringing the two frames 1 closer together until they are against each other, the flip-type connecting component located outside one frame 1 is inserted into the other frame 1 and pushes the extended end of the telescopic connecting component to extend, so that the connector male end 41 is pushed out and plugged into the corresponding connector female end 31; in the process of extending the extended end of the telescopic connecting component, the fuse detachment component undergoes elastic deformation, and after the plate-type thermal fuse 44 is blown, the fuse detachment component pulls the connector male end 41 under the action of elastic potential energy, so that the connector male end 41 and the connector female end 31 are separated from each other.

[0033] More specifically, Figure 4 As shown, the flip-type connection component includes a mounting box 15 mounted on the partition 2, and a rotating rod 6 is rotatably mounted on one end of the mounting box 15 away from the partition 2, and a driving shaft 61 is fixed on the rotating rod 6, and a group of teeth 62 is arranged on the driving shaft 61, and the teeth 62 are arranged in a plurality of groups and are evenly spaced along the axial direction of the driving shaft 61; the rotating rod 6 can be rotated 180 degrees on the mounting box 15 so that the teeth 62 can be located inside or outside the frame 1. It should be noted that a through opening 104 and a through hole 105 are opened on the frame 1, and the through opening 104 and the through hole 105 are respectively arranged on the sides of the two mounting openings 103, and when the rotating rod 6 is flipped 180 degrees to make the teeth 62 located outside the frame 1, the driving shaft 61 can be inserted into the two through openings 104.

[0034] like Figure 5As shown, the telescopic connection component includes a shaft 8, a toothed disc 1 9, a bevel gear rod group 10, a toothed disc 2 11 and a transmission column 15; the toothed disc 1 9 and the toothed disc 2 11 are both rotatably mounted on the partition 2 through an axis, the shaft 8 is fixed on the partition 2, and the toothed disc 1 9 is located beside the shaft 8. The shaft 8 is sequentially rotatably sleeved with a gear 12, a transmission disc 14 and a gear 2 13 in a direction away from the partition 2, the transmission disc 14 is fixedly connected to the gear 2 13, and the transmission disc 14 is fixedly connected to the gear 1 12 through a transmission column 15; the gear 12, the transmission disc 14 and the gear 2 13 rotate synchronously on the shaft 8, and the rotation angle is greater than 90 degrees and less than 180 degrees. Gear 12 is transmission connected to toothed disc 19, toothed disc 19 is transmission connected to bevel gear rod set 10, and one end of bevel gear rod set 10 away from toothed disc 19 is transmission connected to toothed disc 2 11. Specifically, toothed disc 19 and toothed disc 2 11 have the same structure, and are both composed of a cylindrical gear and a large bevel gear coaxially fixedly connected. Bevel gear rod set 10 consists of a rod portion and two small bevel gears connected and fixed at both ends of the rod portion. The small bevel gears are meshedly connected to the corresponding large bevel gears, and gear 12 is meshedly connected to the cylindrical gear next to it.

[0035] The toothed disc 2 11 cooperates with the teeth 62, specifically, the teeth 62 cooperates with the cylindrical gear. When the two frames 1 are brought closer to each other, the drive shaft 61 outside one of the frames 1 can pass through the through hole 105 on the other frame 1 to make the teeth 62 mesh with the cylindrical gear, and gradually penetrate and push the toothed disc 2 11 to rotate in the same direction when the two frames 1 are brought closer to each other, and the bevel gear rod group 10 drives the toothed disc 1 9 to rotate, so as to realize the rotation of the gear 1 12 and the gear 2 13.

[0036] It should be noted that, in this embodiment, two drive shafts 61 are provided, and each drive shaft 61 is provided with a set of teeth 62, and two through openings 104 and through holes 105 are provided; two toothed discs 1 9, bevel gear rod sets 10 and toothed discs 2 11 are provided, and the two toothed discs 1 9 are respectively located on the two discs of the shaft rod 8, and the two toothed discs 1 9 rotate in the same direction, and the two toothed discs 2 11 rotate in the same direction, and the two toothed discs 1 9 are respectively connected to the two toothed discs 2 11 through the two bevel gear rod sets 10. With such a structure, the gear 1 12 and the gear 2 13 can rotate more conveniently.

[0037] Furthermore, if Figure 6 As shown, the telescopic connection component also includes a transmission frame 16 and a push rod 17, the gear 2 13 is transmission-connected to the transmission frame 16, the transmission frame 16 is fixedly connected to the push rod 17, a push shaft 171 is fixedly connected to the push rod 17, the push shaft 171 faces the male end seat 4, and the push shaft 171 is connected to the male end seat 4 through a fuse-disconnecting component. In the process of the drive shaft 61 extending into the frame 1 to rotate the gear 2 13, the transmission frame 16 moves, the push rod 17 extends, the male end seat 4 moves to the side outside the frame 1, and the male end 41 of the connector extends out of the installation port 103.

[0038] like Figure 6 As shown, the fuse disengagement component includes a coil spring 20; the coil spring 20 is sleeved on the shaft 8 located between the gear 12 and the transmission disk 14, and a winding wheel 18 is sleeved on the coil spring 20, one end of the coil spring 20 is fixedly connected to the shaft 8, and the other end of the coil spring 20 is fixedly connected to the winding wheel 18, a pull wire 19 is wound on the winding wheel 18, and one end of the pull wire 19 is fixedly connected to the winding wheel 18, and the other end of the pull wire 19 is fixedly connected to the male end seat 4; in the process of the male end seat 4 moving toward the outer side of the frame 1, the pull wire 19 is pulled out of the winding wheel 18, driving the winding wheel 18 to rotate, so that the coil spring 20 is unwound and elastically deformed; after the plate-type thermal fuse 44 is melted, the coil spring 20 is reset and releases elastic potential energy, so that the winding wheel 18 reels the pull wire 19, pulls the male end seat 4 toward the shaft 8, and moves the connector male end 41 out of the connector female end 31. With such a structure, after the plate-type thermal fuse 44 is blown, the connector male end 41 and the connector female end 31 can be quickly separated, so that the connector male end 41 is powered off, which facilitates the subsequent replacement of the plate-type thermal fuse 44.

[0039] Furthermore, if Figure 6 As shown, the fuse disengagement component also includes an unlocking frame 22 and a locking block 23. The unlocking frame 22 is made of insulating material. The unlocking frame 22 is an L-shaped frame and has a transverse portion and a longitudinal portion, and the connection between the longitudinal portion and the transverse portion is located outside the male end seat 4; the longitudinal portion of the unlocking frame 22 is fixed to the end of the plate-type thermal fuse 44 away from the power connection adapter 42 by screws; it should be noted that in this embodiment, the unlocking frame 22, the plate-type thermal fuse 44 and the power connection adapter 43 are connected and fixed together by the same screw, and the power connection adapter 43 and the male end seat 4 form a mutually slidable bite connection. The transverse portion of the unlocking frame 22 is inserted into the male end seat 4 and slidably cooperates with the male end seat 4.

Specifically, the locking block 23 is provided with a slot 231 that matches the transverse part of the unlocking frame 22. The transverse part of the unlocking frame 22 located in the slot 231 is inclined toward one end of the push shaft 171 and is away from the push shaft 171, so that an inclined transmission structure is formed between the unlocking frame 22 and the locking block 23; it should be noted that when the locking block 23 is sleeved on the push shaft 171, the transverse part of the unlocking frame 22 moves to the bottom of the slot 231 and contacts the bottom surface of the slot 231; the maximum sliding stroke of the locking block 23 when sliding into the male end seat 4 is less than the component of the inclined surface on the transverse part of the unlocking frame 22 in the sliding direction of the locking block 23, so that the transverse part of the unlocking frame 22 is always located in the slot 231; the other end of the unlocking spring 24 is fixedly connected to the male end seat 4, and the unlocking spring 24 is always in a tensile deformation state.

[0041] The fuse disengagement component also includes a tension spring 21, one end of the tension spring 21 is fixedly connected to the male end seat 4, and the connection between the tension spring 21 and the male end seat 4 is located on the side away from the male end 41 of the connector, and the other end of the tension spring 21 is fixedly connected to the longitudinal part of the unlocking frame 22; when the plate-type thermal fuse 44 is in a good state, that is, when the plate-type thermal fuse 44 is not blown, the tension spring 21 is in a stretched state; after the plate-type thermal fuse 44 is blown, the tension spring 21 contracts and resets, pulling the power socket 43 toward the shaft 8, so that the power socket 43 moves a certain distance to the side away from the male end 41 of the connector, and the lateral part of the unlocking frame 22 slides a certain distance outside the male end seat 4 until the tension spring 21 no longer contracts and resets.

[0042] When the lateral part of the unlocking frame 22 slides outward from the male end seat 4, the unlocking spring 24 simultaneously pulls the locking block 23 into the male end seat 4, so that the locking block 23 disengages from the push shaft 171; at the moment when the locking block 23 disengages from the push shaft 171, the coil spring 20 resets and pulls the male end seat 4 toward the shaft 8.

[0043] It should be noted that the spliced ​​LCD display screen also includes an installation box 2 7, which is fixed on the partition 2 by screws, and the shaft rod 8 and the gear disc 1 9 are both located in the installation box 2 7, and the rod portion of the bevel gear rod group 10 passes through and rotates to connect the installation box 2 7, and the small bevel gears at both ends of the rod portion are respectively located inside and outside the installation box 2 7; through the above-mentioned structure, after the installation box 2 7 is removed from the partition 2, the bevel gear rod group 10 can be directly disengaged from the gear disc 1 9 and the gear disc 2 11, and conversely, the bevel gear rod group 10 can be simultaneously meshed and connected to the gear disc 1 9 and the gear disc 2 11, which has the effect of facilitating disassembly and assembly.
