Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display screen manufacturing, in particular to a display screen clamping device and display equipment. BACKGROUND

[0002] The transparent screen is a relatively novel display screen, and the transparent screen is suitable for being made into a relatively large size, and can be used as a screen or glass partition in addition to being used for display.

[0003] The transparent screen usually comprises a grid frame and a light-emitting unit, and LED chips are distributed on one side of the grid frame. The grid frame plays a supporting role, but the grid frame has a plurality of slits and a relatively large area, and therefore has limited structural strength and cannot withstand high-intensity external force. When the transparent screen is maintained, if the grid frame is directly held, damage to the transparent screen is often caused. CONTENT OF THE UTILITY MODEL

[0004] The display screen clamping device and display equipment provided by the embodiments of the present application can facilitate the maintenance of the transparent screen and reduce the risk of damaging the transparent screen. The technical solutions are as follows.

[0005] In a first aspect, the embodiments of the present application provide a display screen clamping device, which is used for clamping a transparent screen, the transparent screen has a plurality of slits, and the display screen clamping device comprises a mounting seat and a clamping mechanism, the clamping mechanism is movably connected with the mounting seat; at least part of the clamping mechanism is used for rotating by a first angle after penetrating through the slits, so as to clamp the transparent screen between the at least part of the clamping mechanism and the mounting seat.

[0006] Based on the above features, by arranging the clamping mechanism on the mounting seat, in the process of clamping the transparent screen, at least part of the clamping mechanism can penetrate through the slits, and then rotate by a first angle. The part of the clamping mechanism penetrating through the slits cooperates with the mounting seat to clamp the transparent screen, which facilitates the disassembly and transfer in the process of display screen maintenance and reduces the risk of damaging the transparent screen.

[0007] In some examples, the clamping mechanism comprises a rotating rod, the rotating rod comprises a stopper and a rod-shaped part, the stopper is located at one end of the rod-shaped part, and the stopper is used for penetrating through the slits; the rod-shaped part penetrates through the mounting seat and can move relative to the mounting seat to drive the stopper to rotate relative to the mounting seat, or to drive the stopper to move close to or away from the mounting seat.

[0008] Based on the above features, by setting the rod-shaped part through the mounting base and enabling the rod-shaped part to move relative to the mounting base to drive the stop part to rotate relative to the mounting base or drive the stop part to move close to or away from the mounting base, when clamping the display screen, the stop part can be first driven by the rod-shaped part to move away from the mounting base, and the stop part can pass through the slits of the grid frame; then the stop part can be driven by the rod-shaped part to rotate relative to the mounting base, and the stop part can be rotated to the outside of the slits, and the stop part and the mounting base clamp the display screen.

[0009] In some examples, the clamping mechanism further comprises a reset assembly, the reset assembly is sleeved outside the rod-shaped part, and the reset assembly is used to provide an action force for driving the stop part to move close to the mounting base.

[0010] Based on the above features, the reset assembly provides the action force for driving the stop part to move close to the mounting base, so that the stop part rotated to the outside of the slits can abut against one side of the grid frame, and the mounting base abuts against the other side of the grid frame to clamp the display screen.

[0011] In some examples, the mounting base comprises a bottom plate and a mounting cylinder, the bottom plate has a first through hole, one end of the mounting cylinder is connected with the bottom plate, and the mounting cylinder is coaxial with the first through hole.

[0012] The rotating rod is located in the first through hole and the mounting cylinder, the stop part is located on the side of the bottom plate away from the mounting cylinder, and the reset assembly is located in the mounting cylinder.

[0013] Based on the above features, the bottom plate can provide a relatively flat and large surface to contact the display screen during clamping of the display screen, so that the clamping is more stable. The mounting cylinder can limit the rotating rod in the axial direction, so that the rotating rod is installed more stably and the shaking of the rotating rod is reduced.

[0014] In some examples, the reset assembly comprises an elastic member, one end of the elastic member abuts against the bottom plate, and the other end is used to apply an action force to the rod-shaped part for driving the rod-shaped part to drive the stop part to move close to the mounting base.

[0015] Based on the above features, during clamping of the display screen, the elastic force of the elastic member enables the stop part and the bottom plate to move close to each other, so that the grid frame is clamped.

[0016] In some examples, the rotating rod further comprises a knob, the knob is located at one end of the rod-shaped part away from the stop part and connected with the rod-shaped part.

[0017] The reset assembly further comprises a sleeve, the sleeve is sleeved outside the rod-shaped part, the sleeve is located between the elastic member and the knob, and the sleeve abuts against the knob under the action of the elastic member.

[0018] Based on the above characteristics, by sleeving a sleeve on the rod-shaped part, the sleeve is used to limit the shaking of the rod-shaped part, plays a role in stabilizing the rotating rod, and improves the stability of the display screen clamping device.

[0019] In some examples, a circumferential limiting structure is arranged between the mounting cylinder and the sleeve, for limiting the relative rotation of the sleeve and the mounting cylinder.

[0020] Based on the above characteristics, by arranging the circumferential limiting structure, the sleeve will not rotate with the rotating rod during the rotation of the rotating rod.

[0021] In some examples, the outer side wall of the sleeve has a guide groove arranged along the axial direction of the sleeve.

[0022] The circumferential limiting structure includes a guide pin connected to the mounting cylinder, which is located in the mounting cylinder and at least partially in the guide groove.

[0023] Based on the above characteristics, the cooperation of the guide pin and the guide groove can not only limit the relative rotation of the sleeve and the mounting cylinder, but also make the movement of the rod-shaped part along the axial direction more stable.

[0024] In some examples, the end face of the sleeve close to the knob has a plurality of protrusions distributed along the circumference of the sleeve.

[0025] The end face of the knob close to the sleeve has a plurality of grooves distributed along the circumference of the knob, and the plurality of grooves are used to accommodate the plurality of protrusions.

[0026] Based on the above characteristics, by arranging the protrusions and the grooves, the knob can be limited to a certain extent, and the knob can remain stable without external force. During the rotation of the knob, the protrusions can slide out of the grooves to release the limitation of the knob.

[0027] In some examples, the mounting seat further includes a first protrusion and a second protrusion, the first protrusion and the second protrusion are located on the side of the bottom plate away from the mounting cylinder, and are respectively connected to the bottom plate, the first protrusion and the second protrusion are used to be inserted into different slits, and the first through hole is located between the first protrusion and the second protrusion.

[0028] Based on the above characteristics, when clamping the display screen, the first protrusion and the second protrusion extend into different slits to support the grid frame.

[0029] In some examples, the display screen clamping device includes a plurality of clamping mechanisms, and the stop portions of the plurality of clamping mechanisms are located on the same side of the mounting seat.

[0030] Based on the above characteristics, in the process of clamping the display screen, the plurality of clamping mechanisms jointly act on the grid frame, so that the display screen is more stable during clamping.

[0031] In some examples, the display screen clamping device further comprises a handle, which is located on the side of the mounting seat away from the stop portion and connected with the mounting seat, and the handle is located between the two clamping mechanisms.

[0032] Based on the above characteristics, by connecting the handle on the mounting seat, the operator can hold the handle conveniently, and the operator can move the display screen conveniently.

[0033] In some examples, the at least part of the clamping mechanism is further used to rotate a second angle to align with the slit, exit from the slit, and separate the transparent screen from the display screen clamping device.

[0034] Based on the above characteristics, after the display screen clamping device is used to maintain the display screen, the part of the clamping mechanism passing through the slit can be rotated by a second angle, so that the clamping mechanism is separated from the display screen.

[0035] In a second aspect, the embodiments of the present application also provide a display device, which comprises a transparent screen and any one of the display screen clamping devices according to the first aspect.

[0036] The technical scheme provided by the embodiments of the present application has at least the following beneficial effects:

[0037] By providing the clamping mechanism on the mounting seat, the clamping mechanism can clamp the display screen in cooperation with the mounting seat. The clamping mechanism comprises a rotating rod and a reset assembly, the rotating rod comprises a stop portion and a rod-shaped portion, and the stop portion is located at one end of the rod-shaped portion. By penetrating the rod-shaped portion through the mounting seat and enabling the rod-shaped portion to move relative to the mounting seat, the stop portion is driven to rotate relative to the mounting seat, or the stop portion is driven to approach or move away from the mounting seat. In the process of clamping the display screen, the rod-shaped portion can first drive the stop portion to move away from the mounting seat, so that the stop portion passes through the slit of the grid frame. Then, the rod-shaped portion drives the stop portion to rotate relative to the mounting seat, so that the stop portion is rotated to the outside of the slit. The reset assembly provides an acting force to promote the stop portion to approach the mounting seat, so that the stop portion rotated to the outside of the slit can be abutted against one side of the grid frame, and the mounting seat is abutted against the other side of the grid frame, thereby clamping the display screen. This facilitates the disassembly and transfer of the display screen in the process of maintenance, and reduces the risk of damaging the transparent screen. BRIEF DESCRIPTION OF DRAWINGS

[0053] Figure 1 is a structural schematic diagram of a display screen provided by an embodiment of the present application, as shown in Figure 1 The display screen is a transparent screen, which includes a grid frame 1000 and a plurality of light emitting units 2000, and the plurality of light emitting units 2000 are distributed on one side of the grid frame 1000. Since the grid frame 1000 has a plurality of slits 1000a, the overall structural strength of the grid frame 1000 is weak, and directly holding the grid frame 1000 during maintenance of the display screen and disassembly can cause the grid frame 1000 to deform, and the risk of damaging the display screen is relatively large.

[0054] The display screen clamping device provided by the embodiment of the present application is used for clamping a transparent screen. The display clamping device comprises a mounting seat 10 and a clamping mechanism 20, and the clamping mechanism 20 is movably connected with the mounting seat 10. At least part of the clamping mechanism 20 is used for rotating by a first angle after passing through a slit 1000a, so as to clamp the transparent screen between the aforementioned at least part of the clamping mechanism 20 and the mounting seat 10, i.e. between the part of the clamping mechanism 20 passing through the slit 1000a and the mounting seat 10.

[0055] By arranging the clamping mechanism 20 on the mounting seat 10, at least part of the clamping mechanism 20 can pass through the slit 1000a during clamping of the transparent screen, and then rotate by a first angle. The part of the clamping mechanism 20 passing through the slit 1000a is matched with the mounting seat 10 to clamp the transparent screen. This facilitates disassembly and transfer during display screen maintenance, and reduces the risk of damaging the transparent screen.

[0056] Exemplarily, the first angle can be 90°. In other examples, the first angle can also be other values, as long as the part of the clamping mechanism 20 passing through the slit 1000a can be offset from the slit 1000a.

[0057] The aforementioned at least part of the clamping mechanism 20 can also be used for rotating by a second angle to align with the slit 1000a, so as to exit from the slit 1000a and separate the transparent screen from the display screen clamping device. In this way, the display screen clamping device can be removed from the transparent screen after maintenance of the transparent screen is completed.

[0058] Exemplarily, the second angle can be the same as the first angle. In other examples, the second angle can also be other values, as long as the part of the clamping mechanism 20 passing through the slit 1000a can align with the slit 1000a.

[0059] Figure 2 is a structural schematic diagram of a display screen clamping device provided by the embodiment of the present application. As shown in Figure 2 The clamping mechanism 20 can comprise a rotating rod 21, and the rotating rod 21 comprises a stop portion 211 and a rod-shaped portion 212. The stop portion 211 is located at one end of the rod-shaped portion 212, and the stop portion 211 is used for passing through the slit 1000a. The rod-shaped portion 212 penetrates through the mounting seat 10, and the rod-shaped portion 212 can move relative to the mounting seat 10 to drive the stop portion 211 to rotate relative to the mounting seat 10, or to drive the stop portion 211 to move close to or away from the mounting seat 10. When clamping the display screen, the stop portion 211 can be first driven by the rod-shaped portion 212 to move away from the mounting seat 10, so as to pass through the slit 1000a of the grid frame 1000; and then the stop portion 211 can be driven by the rod-shaped portion 212 to rotate relative to the mounting seat 10, so as to rotate the stop portion 211 to outside the slit 1000a.

[0060] As shown in Figure 2 The clamping mechanism 20 can further include a reset assembly 22 sleeved outside the rod-shaped portion 212, and the reset assembly 22 is configured to provide an action force for urging the stop portion 211 to approach the mounting base 10.

[0061] In the present example, Figure 3 is a schematic view of a display screen clamped by a display screen clamping device provided by the embodiments of the present application, as shown in Figure 3 The rod-shaped portion 212 is arranged through the mounting base 10 and can move relative to the mounting base 10 to drive the stop portion 211 to rotate relative to the mounting base 10 or to approach or move away from the mounting base 10. When clamping the display screen, the stop portion 211 can be first driven by the rod-shaped portion 212 to move away from the mounting base 10, and the stop portion 211 passes through the slit 1000a of the grating frame 1000. Then, the stop portion 211 is driven by the rod-shaped portion 212 to rotate relative to the mounting base 10, and the stop portion 211 is rotated to the outside of the slit 1000a. The reset assembly 22 provides an action force for urging the stop portion 211 to approach the mounting base 10, so that the stop portion 211 rotated to the outside of the slit can be abutted against one side of the grating frame 1000, and the mounting base 10 is abutted against the other side of the grating frame 1000, thereby clamping the display screen. This facilitates the disassembly and transfer of the display screen during the maintenance process and reduces the risk of damaging the transparent screen.

[0062] As shown in Figure 2 The rotating rod 21 further includes a knob 213, and the knob 213 is located at an end of the rod-shaped portion 212 away from the stop portion 211, and the knob 213 is connected with the rod-shaped portion 212.

[0063] The knob 213 is arranged to enable an operator to drive the rod-shaped portion 212 to rotate by rotating the knob 213, thereby facilitating the operation of the operator.

[0064] The knob 213 can be sleeved at the end of the rod-shaped portion 212. The end surface of the rod-shaped portion 212 can be in a shape other than a circle, so as to lock the knob 213 and the rod-shaped portion 212 in the circumferential direction, and enable the rod-shaped portion 212 to be driven to rotate in the process of rotating the knob 213.

[0065] As shown in Figure 2 The mounting base 10 includes a bottom plate 11 and a mounting cylinder 12, the bottom plate 11 has a first through hole 11a, and one end of the mounting cylinder 12 is connected with the bottom plate 11, and the mounting cylinder 12 is coaxial with the first through hole 11a.

[0066] The rotating rod 21 is located in the first through hole 11a and the mounting cylinder 12, and the stop portion 211 is located on the side of the bottom plate 11 away from the mounting cylinder 12. The reset assembly 22 is located in the mounting cylinder 12.

[0067] The bottom plate 11 can provide a relatively flat and large surface to contact the display screen during clamping, so that the clamping is more stable. The mounting cylinder 12 can limit the rotation of the rotating rod 21 in the axial direction, so that the rotating rod 21 is installed more stably, and the shaking of the rotating rod 21 is reduced.

[0068] As an example, the mounting cylinder 12 and the bottom plate 11 can be detachably connected. For example, the mounting cylinder 12 and the bottom plate 11 can be connected by screws to facilitate the assembly of the clamping mechanism 20. The bottom plate 11 can have a second through hole, and the screws are located in the second through hole and connected to the end surface of the mounting cylinder 12.

[0069] In other examples, the mounting cylinder 12 and the bottom plate 11 can be an integral structure, for example, the mounting seat 10 can be an integrally formed structure, so that the manufacturing cost of the mounting seat 10 is lower.

[0070] Figure 4 is a structural schematic diagram of a display screen clamping device provided by an embodiment of the present application, as shown in Figure 4 The mounting seat 10 further includes a first protrusion 111 and a second protrusion 112, the first protrusion 111 and the second protrusion 112 are located on the side of the bottom plate 11 away from the mounting cylinder 12, the first protrusion 111 and the second protrusion 112 are respectively connected to the bottom plate 11, and the first protrusion 111 and the second protrusion 112 are used for being inserted into different slits 1000a. The first through hole 11a is located between the first protrusion 111 and the second protrusion 112.

[0071] During clamping of the display screen, the first protrusion 111 and the second protrusion 112 are used for being inserted into the slits 1000a of the grid frame 1000. The grid frame 1000 has a plurality of slits 1000a, and during clamping of the display screen, the first protrusion 111, the second protrusion 112 and the stop portion 211 are inserted into different slits 1000a, the stop portion 211 passes through the slit 1000a, and after the rod-shaped portion 212 rotates, the stop portion 211 abuts against the surface of the grid frame 1000 and cooperates with the bottom plate 11 to clamp the display screen, so that the display screen is kept stable. The first protrusion 111 and the second protrusion 112 are located in the slit 1000a, and function to support the grid frame 1000.

[0072] As an example, the first protrusion 111 and the second protrusion 112 can be in the shape of a strip, and the first protrusion 111 and the second protrusion 112 are arranged in parallel and spaced apart. The stop portion 211 can also be in the shape of a strip.

[0073] The side of the bottom plate 11 away from the mounting cylinder 12 can also have a receiving groove 11b, and when the stop portion 211 rotates to the first protrusion 111 and the second protrusion 112, the stop portion 211 can be accommodated in the receiving groove 11b.

[0074] The surface of the bottom plate 11 can also be provided with a flexible layer. For example, the flexible layer can be located on the surface of the bottom plate 11 away from the mounting cylinder 12. During clamping of the display screen, the flexible layer can play a buffering role to prevent the bottom plate 11 from damaging the display screen.

[0075] Exemplarily, the flexible layer can be flannelette.

[0076] As shown in the drawings, Figure 2 The reset assembly 22 includes an elastic member 221. One end of the elastic member 221 abuts against the bottom plate 11, and the other end of the elastic member 221 is used to apply an action force to the rod-shaped portion 212 to make the rod-shaped portion 212 drive the stop portion 211 to approach the mounting seat 10.

[0077] The elastic force of the elastic member 221 on the rod-shaped portion 212 is directed away from the bottom plate 11. The elastic force of the elastic member 221 on the rod-shaped portion 212 can be parallel to the rod-shaped portion 212.

[0078] By arranging the elastic member 221, the rod-shaped portion 212 is pushed by the elastic force of the elastic member 221, so that the stop portion 211 approaches the bottom plate 11. During clamping of the display screen, the elastic force of the elastic member 221 makes the stop portion 211 and the bottom plate 11 approach each other, so as to clamp the lattice frame 1000.

[0079] As shown in the drawings, Figure 2 The reset assembly 22 also includes a sleeve 222. The sleeve 222 is sleeved outside the rod-shaped portion 212, and the sleeve 222 is located between the elastic member 221 and the knob 213. The sleeve 222 abuts against the knob 213 under the action of the elastic member 221.

[0080] The rod-shaped portion 212 and the mounting cylinder 12 have a certain gap to accommodate the elastic member 221. The gap makes the rotating rod 21 prone to shaking, which is not conducive to the stability of the display screen clamping device. By sleeving the sleeve 222 outside the rod-shaped portion 212, the sleeve 222 is used to limit the shaking of the rod-shaped portion 212, so as to stabilize the rotating rod 21 and improve the stability of the display screen clamping device.

[0081] In some examples, a circumferential limiting structure can also be arranged between the mounting cylinder 12 and the sleeve 222. The circumferential limiting structure is used to limit the relative rotation of the sleeve 222 and the mounting cylinder 12.

[0082] By arranging the circumferential limiting structure, the sleeve 222 and the mounting cylinder 12 cannot rotate relative to each other. In this way, during rotation of the rotating rod 21, the sleeve 222 will not rotate with the rotating rod 21.

[0083] As an example, as shown in the drawings, Figure 2 The circumferential limiting structure includes a guide pin 121. The guide pin 121 is connected with the mounting cylinder 12, and the guide pin 121 is located in the mounting cylinder 12.

[0084] Exemplarily, the side wall of the mounting cylinder 12 can have a third through hole 12a, one end of the guide pin 121 is inserted into the third through hole 12a. The guide pin 121 is installed through the third through hole, so that the guide pin 121 can be inserted into the third through hole 12a from the outside of the mounting cylinder 12, and the guide pin 121 enters into the mounting cylinder 12.

[0085] Figure 5 is a schematic view of the cooperation between the sleeve and the guide pin provided by an embodiment of the present application, as shown in Figure 5 The outer side wall of the sleeve 222 has a guide groove 222a, and the guide groove 222a is arranged along the axial direction of the sleeve 222. The guide pin 121 is at least partially located in the guide groove 222a.

[0086] In this example, by arranging the guide groove 222a extending in the axial direction on the side wall of the sleeve 222, and by extending one end of the guide pin 121 into the guide groove 222a, the cooperation between the guide pin 121 and the guide groove 222a can not only limit the relative rotation between the sleeve 222 and the mounting cylinder 12, but also make the axial movement of the rod-shaped part 212 more stable.

[0087] As an example, the two ends of the guide groove 222a can be closed, so that the length of the guide groove 222a can limit the movement range of the sleeve 222, and the sleeve 222 is limited in the mounting cylinder 12, so that the reset assembly 22 is hidden in the mounting cylinder 12, and foreign matters in the outside world are prevented from being stuck in the reset assembly 22, thereby affecting the normal work of the clamping mechanism 20.

[0088] As shown in Figure 5 The end face of the sleeve 222 close to the knob 213 has a plurality of protrusions 2221, and the plurality of protrusions 2221 are distributed along the circumferential direction of the sleeve 222.

[0089] As an example, the sleeve 222 can have four protrusions 2221, and the four protrusions 2221 can be distributed at equal angles along the circumferential direction of the sleeve 222.

[0090] Figure 6 is a structural schematic view of a knob provided by an embodiment of the present application, as shown in Figure 6 The end face of the knob 213 close to the sleeve 222 has a plurality of grooves 213a, and the plurality of grooves 213a are distributed along the circumferential direction of the knob 213. The plurality of grooves 213a are used to accommodate the plurality of protrusions 2221.

[0091] As an example, the knob 213 can have four grooves 213a, and the four grooves 213a can be distributed at equal angles along the circumferential direction of the knob 213.
