Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a holding device and a display screen. Background Technology

[0002] To facilitate operator handling during disassembly, installation, or transportation, display screens typically have gripping devices on their frames. When two adjacent screens are connected, to prevent interference from the gripping devices, they are usually designed to rotate to the back of the screen when not in use, parallel to the screen itself, thus avoiding interference with the installation of adjacent screens. However, if traditional gripping devices are applied to transparent displays, when two adjacent transparent screens are installed together, the narrow frame of the transparent display cannot completely cover the gripping devices. This causes the gripping devices to extend into the transparent display area, obstructing the transparent screen and affecting its transparency. Utility Model Content

[0056] Before implementing the embodiments of this application, the inventors discovered that the handles used for carrying and holding ordinary displays are either temporarily installed on the back of the display when it needs to be moved, or are rotatably mounted on one of the side frames of the display. However, when the above-mentioned commonly used solutions are applied to transparent displays, either there is no supporting foundation, or the frame of the transparent display is too narrow, causing the handle to obstruct the transparent screen when it is in the storage state, thereby affecting the display effect of the transparent display.

[0057] Based on this, the inventors of this application attempted to develop a gripping device suitable for a narrow frame of a transparent display screen. When it needs to be moved, the gripping device is located outside the frame. When it does not need to be moved, the gripping device is housed inside the side frame and does not protrude from the side frame. This way, it will not affect the installation of two adjacent transparent screens, nor will it obstruct the transparent screen body, thus ensuring a good display effect of the transparent screen. The following embodiments are thus developed.

[0058] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0059] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0060] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0061] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0062] This application provides a display screen, which includes a frame and a screen body located on one side of the frame. The frame supports the screen body to ensure that the display screen has sufficient strength and to ensure that there is a connection base between two adjacent display screens.

[0063] Please refer to Figure 1 As shown, to facilitate the handling of the display screen, the display screen of this application also includes a holding device 1. The frame includes multiple side frames 2 connected end to end in sequence. The holding device 1 is embedded in the side frames 2. When the display screen needs to be moved, the holding device 1 can be moved out of the side frames 2 for easy gripping by the operator. When the display screen does not need to be moved, the holding device 1 is housed in the side frames 2 and does not protrude from the side frames 2. This not only does not affect the connection between two adjacent display screens, but also does not obstruct the screen body. Therefore, the holding device 1 of this application embodiment can be applied not only to ordinary display screens, but also to transparent display screens. When the holding device 1 is housed in the side frames 2, the holding device 1 will not obstruct the transparent screen body of the transparent display screen, will not affect the transparency of the transparent display screen, and ensures a good display effect of the transparent display screen.

[0064] Specifically, please refer to Figure 1As shown, in some embodiments of this application, the holding device 1 includes a mounting base 11 and a handle assembly 12. A mounting groove is provided on the side of the side frame 2 facing inwards. The mounting base 11 is located within the mounting groove. The handle assembly 12 is rotatably mounted on the mounting base 11 and has a first position and a second position. When in the first position, the handle assembly 12 is retracted into the mounting groove, and the holding device 1 does not protrude from the side frame 2. When in the second position, the handle assembly 12 is located outside the mounting groove and perpendicular to the mounting base 11. In this position, the operator can hold the handle to move the display screen.

[0065] It is understandable that, since transparent displays typically employ extremely narrow frames, and these frames are small in both the inward and outward dimensions, as well as in the directions toward and away from the screen, the distance between the handle assembly 12 and the frame is relatively small when in the second position. This results in limited space for the operator to hold the handle assembly 12, making it difficult for them to grip it. Therefore, in some embodiments of this application, please refer to... Figures 1-4 As shown, the length of the handle assembly 12 is adjustable. When the handle assembly 12 is in the second position, the length of the handle assembly 12 can be extended to facilitate the operator's grip. When the handle assembly 12 is in the first position, the length of the handle assembly 12 can be shortened to facilitate the handle being accommodated in the mounting slot.

[0066] Further, please refer to Figures 2-4 As shown, in some embodiments of this application, the handle assembly 12 includes a telescopic handle 121 and a first rotating shaft 122. When the handle assembly 12 is in the first position, the telescopic handle 121 surrounds the mounting base 11 circumferentially. The first rotating shaft 122 passes through the mounting base 11, and its two ends are connected to the telescopic handle 121 on the corresponding side, thereby allowing the telescopic handle 121 to rotate relative to the mounting base 11 to switch the handle assembly 12 between the first position and the second position. The telescopic handle 121 has a telescopic state and an extended state, and the length of the handle assembly 12 is adjusted by telescopically extending the handle 121. It is understood that when the handle assembly 12 is in the first position, in order to facilitate the telescopic handle 121 being accommodated in the mounting groove, the telescopic handle 121 is in the retracted state. At this time, due to the restriction of the groove wall, the telescopic handle 121 cannot switch from the retracted state to the extended state. When the handle assembly 12 is in the second position, since there is no longer a mounting slot, the telescopic handle 121 can switch between the telescopic state and the extended state. It should be noted that the telescopic handle 121 can switch between the telescopic state and the extended state not only when the handle assembly 12 is in the second position. The telescopic handle 121 can switch between the telescopic state and the extended state as long as it is disengaged from the mounting slot. As for when the telescopic handle 121 switches states in actual practice, this application embodiment does not make specific limitations.

[0067] Please refer to Figures 2-4 As shown, in some embodiments of this application, the telescopic handle 121 includes a rotating rod 1211 and a connecting rod 1212. The mounting base 11 has a rotating rod 1211 on each side. The two ends of the first rotating shaft 122 are connected to the rotating rod 1211 on the corresponding side, and the other end has a telescopic hole. The connecting rod 1212 has telescopic rods 1213 on both ends. The telescopic rods 1213 are movably disposed in the corresponding telescopic holes. The telescopic rods 1213 move along the telescopic holes to realize the switching of the telescopic handle 121 from the extended state to the retracted state. The structure is simple and easy to implement.

[0068] To prevent the telescopic rod 1213 from disengaging from the telescopic hole during state switching of the telescopic handle 121, please refer to... Figures 2-4 As shown in some embodiments of this application, one of the telescopic rod 1213 and the wall of the telescopic hole is provided with a protrusion, and the other is provided with a groove 1111. The protrusion can slide in the groove 1111, which not only allows the telescopic rod 1213 to slide smoothly in the telescopic hole, but the groove walls at both ends of the groove 1111 also play a limiting role. Under the resistance of the groove walls, the protrusion cannot disengage from the groove 1111, thereby preventing the connecting rod 1212 from disengaging from the rotating rod 1211. The telescopic rod 1213 may have a protrusion and the wall of the telescopic hole may have a groove 1111, or the wall of the telescopic hole may have a protrusion and the telescopic rod 1213 may have a groove 1111. As long as the protrusion can slide in the groove 1111, this application does not impose any specific limitations.

[0069] Further, please refer to Figures 2-4As shown, in some embodiments of this application, the handle assembly 12 further includes a first limiting structure 124 and a second limiting structure 125 that cooperate with each other. The first limiting structure 124 is provided on one of the walls of the telescopic hole and the connecting rod 1212, and the second limiting structure 125 is provided on the other. Two first limiting structures 124 or second limiting structures 125 are spaced apart. When the telescopic handle 121 is in the retracted or extended state, the first limiting structure 124 and the corresponding second limiting structure 125 cooperate and connect. This further limits the connecting rod 1212, preventing the telescopic handle 121 from extending or retracting without human intervention and avoiding arbitrary switching of the telescopic handle 121's state. It also emits a prompt sound to indicate to the operator that the telescopic handle 121 has been switched to the correct position. In some embodiments of this application, the first limiting structure 124 can be a ball bearing, and the second limiting structure 125 is a ball bearing groove. The ball bearing is disposed on the telescopic rod 1213, and two ball bearing grooves are spaced apart on the wall of the telescopic hole. When the telescopic handle 121 is in the retracted state, the ball bearing is accommodated in the ball bearing groove located near the first rotating shaft 122. When the telescopic handle 121 is in the extended state, the ball bearing is accommodated in the ball bearing groove located away from the first rotating shaft 122. If the telescopic rod 1213 is to move within the telescopic hole, the ball bearing must first be removed from the ball bearing groove, thereby preventing the telescopic handle 121 from arbitrarily switching states. When the telescopic handle 121 switches to different states, the ball bearing, momentarily contained in the corresponding ball bearing groove, will collide with the groove wall, producing a sound to indicate to the operator that the state has been switched to the correct position, and there is no need to continue moving the telescopic rod 1213. Alternatively, there could be two beads and one bead groove, with the two beads spaced apart on the telescopic rod 1213. Or, the telescopic rod 1213 could have a groove, and the telescopic hole wall could have beads. As long as the telescopic handle 121 can be extended or retracted, the beads can be accommodated in the corresponding bead groove. The specific structure can be set according to the actual situation, and this application does not impose any specific limitations.

[0070] Understandably, the handle assembly 12 can automatically rotate back into the mounting slot under gravity, requiring the operator to unscrew it while holding the handle assembly. Furthermore, if the handle assembly rotates around the first pivot 122 when the operator applies a moving force, it could not only cause the operator's hand to be pinched, but also make it difficult for the operator to apply force. Therefore, please refer to... Figures 2-4As shown, in some embodiments of this application, the handle assembly 12 further includes a first reset member 123, which is sleeved on the first rotating shaft 122. When the handle assembly 12 is in the first position, the first reset member 123 is compressed. When the handle assembly 12 needs to switch from the first position to the second position, the handle assembly 12 rotates under the elastic force of the first reset member 123, thereby realizing the automatic switching of the handle assembly 12. Furthermore, when the handle assembly 12 is in the first position, the handle assembly will not automatically rotate back into the mounting groove under the action of the first reset member 123, thus facilitating the operator's operation and grip, preventing hand pinching, and making it easier to apply force.

[0071] After the display screen is moved, the operator applies a rotational force to the handle assembly 12, causing it to rotate towards the mounting slot. This compresses the first reset member 123, placing the handle assembly 12 within the mounting slot. The first reset member 123 is then compressed to its minimum position. If the rotational force is removed at this point, the handle assembly 12 will switch back to its second position under the elastic force of the first reset member 123. Therefore, please refer to... Figures 2-4 As shown, in some embodiments of this application, the holding device 1 further includes a locking component 13. When the handle component 12 is in the first position, the locking component 13 can lock the handle component 12 to prevent the handle component 12 from switching automatically. When the handle component 12 needs to switch from the first position to the second position, the locking component 13 can be operated to unlock.

[0072] Specifically, please refer to Figures 2-4 As shown, in some embodiments of this application, the locking component 13 is retractably mounted on the mounting base 11, and the retractable handle 121 is provided with a locking groove 1214 that cooperates with the locking component 13. The locking component 13 extends out of the mounting base 11 and into the locking groove 1214 to lock the handle component 12 in the first position. When the locking component 13 retracts into the mounting base 11, the handle component 12 is unlocked. At this time, the handle component 12 automatically switches from the first position to the second position under the action of the elastic force of the first reset member 123.

[0073] Please refer to Figures 2-4As shown, in some embodiments of this application, the locking component 13 includes a button 131 and a telescopic pin 132. The button 131 is movable on the mounting base 11 in a direction that extends inward or outward from the frame, and has an unlock position and a locked position. The telescopic pin 132 is movable and passes through the side of the mounting base 11 in a direction that extends along the side frame 2. The telescopic pin 132 abuts against the button 131. When the button 131 is in the unlock position, the telescopic pin 132 retracts into the mounting base 11. When the button 131 is in the locked position, the telescopic pin 132 extends out of the mounting base 11. By pressing the button 131, the telescopic pin 132 can be moved telescopically on the mounting base 11, so that the locking component 13 can extend or retract from the mounting base 11, which is convenient for the operator to operate.

[0074] For details, please refer to Figures 2-4 As shown, in some embodiments of this application, the button 131 has a guide surface 1311 on the side away from the frame. The guide surface 1311 extends from the button 131 along the length of the side frame 2 towards the center and tilts outward from the frame. The telescopic pin 132 includes a pin body 1321 and an abutment shaft 1322 passing through one end of the pin body 1321. The pin body 1321 passes through the button 131, and the abutment shaft 1322 abuts against the guide surface 1311 and can slide along the guide surface 1311. When pressure is applied to the button 131, the button 131 moves from the side inside the frame towards the outside of the frame. The pressure is applied to the abutment shaft 1322 through the guide surface 1311, so as to give the abutment shaft 1322 the power to move along the mounting base 11, thereby causing the telescopic pin 132 to retract into the mounting base 11, so as to unlock the handle assembly 12 from the first position by the locking assembly 13.

[0075] To ensure the stability of the lock, please refer to... Figures 2-4 As shown, in some embodiments of this application, there are two telescopic pins 132. A telescopic pin 132 is movably provided on each side of the mounting base 11. Guide surfaces 1311 are provided on both sides of the button 131 facing away from the frame, extending along the direction of the side frame 2. The telescopic pin 132 passes through the button 131 on the corresponding side, causing the abutting shaft 1322 to abut against the guide surface 1311 on the corresponding side. When pressure is applied to the button 131 towards the outside of the frame, the two guide surfaces 1311 provide power to the corresponding abutting shaft 1322 to move towards the inside of the mounting base 11, causing both telescopic pins 132 to move towards the inside of the mounting base 11 and retract into the mounting base 11, thereby unlocking the handle assembly 12 in the first position.

[0076] Please refer to Figures 2-4As shown, in some embodiments of this application, the locking component 13 further includes a second reset member 133. The pin 1321 is provided with an abutment platform 1324 on the side away from the button 131. The mounting base 11 is provided with a sliding groove 1111 on the side. The abutment platform 1324 is slidably disposed in the sliding groove 1111. The second reset member 133 is sleeved on the pin 1321, with one end abutting against the groove wall of the sliding groove 1111 and the other end abutting against the abutment platform 1324. The pin 1321 extends into the mounting base 11, and the second reset member 133 is compressed. When the pressure applied to button 131 is removed, under the elastic force of the second compression member resetting, the telescopic pin 132 moves toward the direction of extending out of the mounting base 11, and the abutting shaft 1322 exerts a force on the guide surface 1311 in the direction away from the mounting base 11. Under the action of this force, the abutting shaft 1322 moves along the guide surface 1311, causing the guide surface 1311 to move toward the direction of the frame, thereby realizing the automatic switching of button 131 from the unlock position to the locked position.

[0077] For ease of use, please refer to... Figures 2-4 As shown, in some embodiments of this application, the locking groove 1214 is located on the rotating rod 1211, and the end of the telescopic pin 132 extending out of the mounting base 11 is provided with an inclined surface 1323. When the handle assembly is switched from the second position to the first position, the rotating rod 1211 first abuts against the inclined surface 1323 and applies a force to the inclined surface 1323 toward the mounting groove. Driven by this force, the telescopic rod 1213 moves toward the mounting base 11 until the handle assembly is switched to the first position, the locking groove 1214 is aligned with the telescopic rod 1213, and the telescopic rod 1213 automatically extends into the locking groove 1214 under the elastic force of the second reset member 133 to achieve automatic locking of the handle assembly.

[0078] Please refer to Figures 2-4 As shown, in some embodiments of this application, the mounting base 11 includes a base body 111 and a cover 113. A first rotating shaft 122 passes through the base body 111, and a locking assembly 13 is telescopically mounted on the base body 111. The side of the base body 111 facing the frame has an operating groove 112. A button 131 is movably mounted in the operating groove 112. The cover 113 covers the operating groove 112 and has an operating hole 114. The operating hole 114 covers part of the button 131 to restrict the position of the button 131 and prevent the button 131 from disengaging from the operating groove 112. The operating hole 114 allows an operator to pass through to apply pressure to the button 131, causing the button 131 to switch from the locked position to the unlocked position.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
