Description

Technical Field

[0001] This utility model applies to the field of display screen technology, and in particular relates to a built-in buffer mechanism for display screens. Background Technology

[0002] Currently, displays are widely used in various electronic devices, such as televisions, computers, and mobile phones. With the development of technology, people have increasingly higher requirements for displays.

[0003] However, currently, when transporting displays, they are often placed inside foam boxes. To improve the cushioning and protection provided by these boxes, it's often necessary to customize the foam box to match the thickness and dimensions of the display itself, ensuring adequate protection. However, during actual transport, the display itself lacks a corresponding support and cushioning mechanism. If the foam box size is incompatible, it can easily fail to adequately protect the display, causing it to shake inside the box and become damaged, affecting subsequent normal use. Therefore, we propose a built-in cushioning mechanism for displays. Utility Model Content

[0004] The main objective of this invention is to provide a built-in buffer mechanism for a display screen, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A built-in buffer mechanism for a display screen, wherein the display screen housing has vertically opened mounting slots at both ends of its side, and a hollow frame is fixedly embedded in each mounting slot, and a fixing frame is horizontally fixedly installed at the middle of the side of the display screen housing;

[0007] Each hollow frame is equipped with a transmission mechanism inside, and each hollow frame has a bonding plate that is movably attached to its side, and the bonding plate and the transmission mechanism are connected in a transmission manner.

[0008] Each of the fixed frames is equipped with a drive mechanism.

[0009] By adopting the above technical solution, the distance between the bonding plate and the outer side of the display screen housing can be adjusted through the cooperation of the transmission mechanism and the drive mechanism, so as to ensure that the bonding plate can be attached to the inner wall of the foam box where the display screen housing is to be stored, thereby enabling the display screen housing to be stably placed inside foam boxes of different storage sizes and improving the stability of the display screen during transportation.

[0010] As an optional solution to the technical solution of this application, the transmission mechanism includes a sliding sleeve and a transmission rod. A guide rod is vertically fixedly installed inside each hollow frame. A sliding sleeve is slidably sleeved at both ends of the outer side of each guide rod. A transmission rod is obliquely hinged to the outer side of each sliding sleeve through a rotating shaft. The side of the transmission rod away from the sliding sleeve is hinged to the side of the bonding plate through a rotating shaft.

[0011] By adopting the above technical solution, the horizontal position of the bonding plate can be adjusted by the guiding sliding action of the guide rod on the sliding sleeve and the transmission conversion action of the transmission rod.

[0012] As an optional solution to the technical solution of this application, the driving mechanism includes a rotating lead screw, a transmission bevel gear, and a follower bevel gear. The rotating lead screw is rotatably mounted laterally on both sides of the inside of the fixed frame via bearings. A transmission sleeve is movably sleeved on the outside of each rotating lead screw. A connecting frame is fixedly mounted on the outside of each sliding sleeve and the transmission sleeve. A push rod is inclinedly hinged between the outside of the two sets of connecting frames via a rotating shaft. A follower bevel gear is fixedly sleeved on the side of each rotating lead screw away from the hollow frame. A rotating rod is rotatably mounted on the middle of the side of the fixed frame via bearings. A transmission bevel gear is fixedly sleeved on the side of the rotating rod close to the rotating lead screw, and the outer sides of the transmission bevel gear and the follower bevel gear mesh with each other.

[0013] By adopting the above technical solution, through the meshing transmission action of the transmission bevel gear and the follower bevel gear, and through the rotation transmission action of the rotating screw on the transmission sleeve, the synchronous transmission adjustment of the push rod and the transmission rod on the bonding plate can be guaranteed, ensuring that the movement adjustment distance of the two sets of bonding plates is the same, so that the display screen housing will not tilt when stored and placed, affecting the stability of the storage and placement.

[0014] As an optional solution to the technical solution of this application, a connecting plate is fixedly installed on the side of the rotating rod away from the transmission bevel gear, and a tightening bolt is screwed through the middle of the connecting plate by a thread. A friction plate is fixedly installed on the side of the tightening bolt near the display screen housing.

[0015] By adopting the above technical solution, the structure of the clamping bolt and the friction plate ensures that the clamping bolt can be tightened so that the friction plate can move and fit against the outside of the fixed frame, thereby fixing the rotation of the rotating rod.

[0016] As an optional solution to the technical solution of this application, the hollow frame is provided with a limiting groove on the side near the fixed frame and the top of the fixed frame, and the push rod and the transmission rod are slidably inserted into the limiting groove.

[0017] By adopting the above technical solution, the guiding and limiting effect of the limiting groove on the push rod and the transmission rod ensures the rationality of the transmission of the entire device.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. A built-in buffer mechanism for a display screen, comprising a hollow frame and a fixed frame embedded inside the display screen housing, and a transmission mechanism and a drive mechanism working together, allows the operator to rotate a rotating rod, causing two sets of rotating screws to rotate synchronously. The rotating screws, in turn, drive the transmission sleeves, enabling the two sets of transmission sleeves to move horizontally in opposite directions within the fixed frame. Furthermore, the push rod, through its transmission conversion action, drives two sets of sliding sleeves located on either side of the hollow frame to move vertically in opposite directions. This, in turn, provides a corresponding push-pull force to the bonding plate, adjusting the distance between the bonding plate and the outer side of the display screen housing. This ensures the bonding plate adheres to the inner wall of the foam box containing the display screen housing, allowing the display screen housing to be stably placed inside foam boxes of different sizes, thus improving the stability of the display screen during transport.

[0020] 2. The built-in buffer mechanism for a display screen in this application, through the meshing transmission action of the transmission bevel gear and the follower bevel gear, allows the operator to drive the rotating screws located on both sides inside the fixed frame to rotate synchronously by simply turning the rotating rod on the inside and outside of the fixed span. This ensures the synchronous transmission adjustment of the push rod and the transmission rod on the bonding plate, and ensures that the movement adjustment distance of the two sets of bonding plates is the same, so that the display screen housing will not tilt when stored and placed, thus affecting the stability of the storage and placement.

[0025] like Figure 1-3 As shown, this utility model provides a technical solution: a built-in buffer mechanism for a display screen, wherein the display screen housing 1 has vertically opened mounting grooves 11 at both ends of its side, and a hollow frame 12 is fixedly embedded in each mounting groove 11, and a fixing frame 13 is horizontally fixedly installed at the middle of the side of the display screen housing 1.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), each hollow frame 12 is equipped with a transmission mechanism, which includes a sliding sleeve 25 and a transmission rod 26. Each hollow frame 12 is vertically fixed with a guide rod 24. Each guide rod 24 is slidably sleeved with a sliding sleeve 25 at both ends on its outer side. Each sliding sleeve 25 is inclinedly hinged to a transmission rod 26 on its outer side via a rotating shaft. The side of the transmission rod 26 away from the sliding sleeve 25 is hinged to the side of the bonding plate 27 via a rotating shaft.

[0027] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), each fixed frame 13 is equipped with a drive mechanism, which includes a rotating lead screw 2, a transmission bevel gear 31, and a follower bevel gear 32. The rotating lead screw 2 is installed laterally on both sides of the fixed frame 13 via bearings. A transmission sleeve 21 is movably sleeved on the outside of each rotating lead screw 2. A connecting frame 23 is fixedly installed on the outside of each sliding sleeve 25 and the transmission sleeve 21. A push rod 22 is inclinedly hinged between the two sets of connecting frames 23 via a rotating shaft. A limiting groove 28 is opened on the side of the hollow frame 12 near the fixed frame 13 and on the top of the fixed frame 13. The push rod 22 and the transmission rod 26 are slidably inserted into the limiting groove 28.

[0028] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), each rotating screw 2 is fixedly sleeved with a follower bevel gear 32 on the side away from the hollow frame 12. A rotating rod 3 is rotatably installed on the middle side of the fixed frame 13 via a bearing. A transmission bevel gear 31 is fixedly sleeved on the side of the rotating rod 3 close to the rotating screw 2, and the transmission bevel gear 31 and the follower bevel gear 32 mesh with each other on the outer side.

[0029] In some technical solutions (through Figure 1 , Figure 2 and Figure 3 As shown), a connecting plate 4 is fixedly installed on the side of the rotating rod 3 away from the transmission bevel gear 31. A tightening bolt 41 is screwed through the middle of the connecting plate 4 by a thread. A friction plate 42 is fixedly installed on the side of the tightening bolt 41 near the display screen housing 1.

[0030] During operation, after placing the display screen housing 1 into the storage slot inside the foam box to be stored, the tightening bolt 41 is tightened to simultaneously disengage the friction plate 42 on its side from the outside of the fixed frame 13. Then, the operator tightens the rotating rod 3, causing the transmission bevel gear 31 to rotate synchronously inside the fixed frame 13. The meshing transmission action of the transmission bevel gear 31 and the follower bevel gear 32 drives the rotating screw rods 2 located on both sides inside the fixed frame 13 to rotate synchronously. Combined with the guiding and limiting effect of the limiting groove 28 on the push rod 22, and the rotational transmission action of the rotating screw rod 2 on the transmission sleeve 21, the two sets of transmission sleeves 21 can move horizontally relative to each other inside the fixed frame 13. The transmission of the push rod 22... Under the action of dynamic conversion, the horizontal moving force of the transmission sleeve 21 can be converted into a vertical pushing force on the sliding sleeve 25, so that the sliding sleeve 25 can move vertically relative to the outside of the guide rod 24. Then, combined with the transmission conversion action of the transmission rod 26, the vertical moving force of the sliding sleeve 25 can be converted into a horizontal pushing force on the bonding plate 27, so that the bonding plate 27 can be separated from the outer wall of the hollow frame 12 and move outward until the bonding plate 27 moves and can be attached to the inner wall of the storage slot inside the foam box. After the display screen housing 1 is placed inside the foam box, the bonding plate 27 can be attached to the inner wall of the foam box to perform abutment and limit treatment on the display screen housing 1, improve the stability of the display screen housing 1 during transportation and placement, and prevent it from shaking and being damaged.
