Description

Technical Field

[0001] This invention relates to the technical field of displays, and more particularly to a fully automatic corner protection device for displays. Background Technology

[0002] With the increasing application of LED displays, the requirements for LED display protection devices are also becoming more stringent, especially for display screen protection. Currently, most corner protectors on the market are semi-automatic, but their operation is complex. Since corner protectors are structures used to protect the support base of the LED display from damage, they are usually in an extended state to protect the support base. However, when splicing LED displays, the splicing process needs to be completed quickly and conveniently. At this time, the corner protectors need to be retracted to prevent mechanical interference. Therefore, it is necessary to solve the technical problem of preventing accidental retraction of the corner protectors to protect the display in the normal state, and quickly retracting the corner protectors to avoid interference during display splicing. Summary of the Invention

[0003] The purpose of this invention is to provide a fully automatic corner protection device for displays, which aims to solve the technical problems of preventing accidental retraction of the corner protectors to protect the displays under normal conditions, and rapidly retracting the corner protectors to avoid interference during display splicing.

[0004] To solve the above-mentioned technical problems, a fully automatic corner protection device for a display screen is provided, including a corner protector, a slide, a first elastic member, and a top post. The corner protector has a sliding part and a stepped hole. The slide includes a sliding groove, a connecting part, and a first insertion hole. The sliding groove is formed on the slide, and the sliding part is slidably connected to the sliding groove to allow the corner protector to slide and retract or expand on the slide. The connecting part is spaced apart from the sliding groove, and the first insertion hole passes through the slide facing the stepped hole. The two ends of the first elastic member are respectively connected to the sliding part and the connecting part to allow the corner protector to return to its original position and slide on the slide. The top post is inserted into the first insertion hole, and the top post elastically abuts against the stepped hole to limit the sliding of the corner protector relative to the sliding groove.

[0005] Furthermore, the sliding groove is formed on the slide block at an angle from near to far relative to the corner protector, so that the corner protector can slide closer to or further away from the slide block.

[0006] Furthermore, the fully automatic corner protection device for the display screen also includes a first connecting post, and the sliding part has a second insertion hole. The first connecting post passes through the second insertion hole and the sliding groove hole, and the first connecting post slides in the sliding groove hole, thereby driving the sliding part to slide relative to the sliding groove hole.

[0007] Furthermore, one end of the first connecting post is provided with a locking tooth portion, which engages with the inner wall of the second insertion hole.

[0008] Furthermore, the corner protector has a first side surface near the slide block, and the slide block has a second side surface near the corner protector. The first side surface has a smooth groove, and the stepped hole passes through the smooth groove. When the corner protector is retracted into the slide block, the second side surface slides against the smooth groove.

[0009] Furthermore, the stepped hole includes a snap-fit ​​groove, the top post includes a snap-fit ​​connector and a post body connected to the snap-fit ​​connector, the post body is inserted into the first insertion hole, and the snap-fit ​​connector is elastically snapped into the snap-fit ​​groove to restrict the corner protector from sliding relative to the slide block.

[0010] Furthermore, the fully automatic corner protection device for the display screen also includes a second elastic element, which is sleeved on the column body, and both ends of the second elastic element abut against the snap-fit ​​connector and the first insertion hole, respectively.

[0011] Furthermore, the fully automatic corner protection device for the display screen also includes a second connecting post, the connecting part forms a third insertion hole, the second connecting post is inserted into the third insertion hole, and the first elastic member is elastically connected to the second connecting post and the first connecting post.

[0012] Furthermore, the first connecting post is provided with a first socket groove, the second connecting post is provided with a second socket groove, and the two ends of the first elastic member are respectively connected to the first socket groove and the second socket groove.

[0013] Furthermore, when splicing the display screen, the two oppositely arranged top pillars abut against each other, so that the top pillars disengage from the stepped holes, thereby releasing the restriction on the sliding of the corner protectors relative to the sliding groove holes.

[0014] Implementing the embodiments of the present invention will have the following beneficial effects:

[0015] The fully automatic corner protection device for the display screen in this embodiment allows the corner protectors to slide and retract or expand on the slide block, thus enabling them to quickly retract during display screen splicing to avoid mechanical interference. In addition, since the top post abuts against the stepped hole, the sliding of the corner protectors relative to the slide block is restricted, overcoming the problems of accidental retraction of the corner protectors in the normal state and the need for rapid retraction during display screen splicing in the prior art.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please refer to Figures 1-3This invention provides a fully automatic corner protection device 100 for a display screen, including a corner protector 110, a slide 120, a first elastic member 130, and a top post 140. The corner protector 110 has a sliding part 111 and a stepped hole 112. The slide 120 includes a sliding groove 121, a connecting part 122, and a first insertion hole 123. The sliding groove 121 is formed on the slide 120, and the sliding part 111 is slidably connected to the sliding groove 121, so that the corner protector 110 slides, retracts, or expands. A connecting portion 122 is provided at intervals between the sliding groove hole 121 and the slide block 120. A first insertion hole 123 passes through the slide block 120 facing the stepped hole 112. The two ends of the first elastic member 130 are respectively connected to the sliding portion 111 and the connecting portion 122 so that the corner protector 110 is reset and slides on the slide block 120. The top post 140 is inserted into the first insertion hole 123 and elastically abuts against the stepped hole 112 to limit the sliding of the corner protector 110 relative to the sliding groove hole 121. In specific applications, the corner protector 110 is located at the corner of the display screen. The corner protector 110 at the corner of the display screen is used to protect the display screen from damage during collisions. Therefore, under normal conditions, the top post 140 elastically abuts against the stepped hole 112, thereby limiting the sliding of the corner protector 110 relative to the slide hole 121, thus preventing the corner protector 110 from accidentally retracting and playing a good protective role. When the display screen needs to be spliced, the top post 140 separates from the stepped hole 112. Since the sliding part 111 is slidably connected to the slide hole 121, the corner protector 110 can slide and retract onto the slide base 120. This allows for quick assembly during display screen splicing. In addition, after the display screen is disassembled, the corner protector 110 is reset relative to the slide base 120 under the elastic force of the first elastic member 130, and the top post 140 abuts against the stepped hole 112 again. This allows the corner protector 110 to open relative to the slide base 120 to protect the display screen.

[0030] In one possible implementation, the sliding groove 121 is formed on the slide base 120 at an angle from near to far relative to the corner protector 110, so that the corner protector 110 slides closer to or further away from the slide base 120. In specific applications, when the sliding part 111 is slidably connected to the sliding groove 121 closest to the slide base 120, the corner protector 110 retracts onto the slide base 120. This retraction is achieved through a gradual, inclined retraction, allowing the corner protector 110 to slide and retract onto the slide base 120. When the sliding part 111 is slidably connected to the sliding groove 121 away from the slide base 120, the corner protector 110 is tilted and extended onto the slide base 120, and the top post 140 abuts against the step, thereby protecting the display screen.

[0031] In one possible implementation, the fully automatic corner protection device 100 for the display screen further includes a first connecting post 150. The sliding portion 111 has a second insertion hole 1111. The first connecting post 150 passes through the second insertion hole 1111 and the sliding groove hole 121, and slides in the sliding groove hole 121, thereby causing the sliding portion 111 to slide relative to the sliding groove hole 121. In specific applications, to enable the sliding portion 111 to slide relative to the sliding groove hole 121, the sliding portion 111 has a second insertion hole 1111. The first connecting post 150 passes through the second insertion hole 1111 and the sliding groove hole 121, and slides in the sliding groove hole 121. Two sliding portions 111 are symmetrically formed vertically, with the first connecting post 150 inserted on the upper portion. This makes the sliding connection of the sliding portion 111 relative to the sliding groove hole 121 more stable.

[0032] In one possible implementation, one end of the first connecting post 150 is provided with a retaining tooth 151, which engages with the inner wall of the second insertion hole 1111. In specific applications, to prevent the first connecting post 150 from falling off, a retaining tooth 151 is provided on the side of one end of the first connecting post 150. This retaining tooth 151 engages with the inner wall of the second insertion hole 1111, thereby preventing the first connecting post 150 from falling off into the second insertion hole 1111 and ensuring the normal sliding of the corner protector relative to the slide block 120. Furthermore, it is worth noting that the retaining tooth 151 engages with the inner wall of the second insertion hole 1111, thereby preventing the first connecting post 150 from rotating, thus making the first connecting post 150 more securely engaged in the second insertion hole 1111.

[0033] In one possible implementation, the corner protector 110 has a first side surface 113 near the slide block 120, and the slide block 120 has a second side surface 124 near the corner protector 110. The first side surface 113 has a smooth groove 1131, and a stepped hole 112 passes through the smooth groove 1131. When the corner protector 110 retracts into the slide block 120, the second side surface 124 slides against the smooth groove 1131. In specific applications, the smooth groove 1131 is milled on the first side surface 113 with a milling cutter, thereby reducing the roughness of the contact surface between the slide block 120 and the corner protector 110. This allows the corner protector 110 to slide more smoothly on the smooth groove 1131, avoiding problems such as jamming. It is worth noting that the smooth groove 1131 only needs to be milled to the size of the contact area with the second side surface 124, thereby reducing the manufacturing cost and improving production efficiency.

[0034] In one possible implementation, the stepped hole 112 includes a snap-fit ​​groove 1121, and the top post 140 includes a snap-fit ​​connector 141 and a post body 142 connected to the snap-fit ​​connector 141. The post body 142 is inserted into the first insertion hole 123, and the snap-fit ​​connector 141 is elastically snapped into the snap-fit ​​groove 1121 to restrict the corner protector 110 from sliding relative to the slide block 120. In specific applications, the snap-fit ​​groove 1121 of the stepped hole 112 is used to snap the snap-fit ​​connector 141 of the top post 140, which can restrict the corner protector 110 from sliding relative to the slide block 120. When the snap-fit ​​connector 141 disengages from the snap-fit ​​groove 1121, the restriction on the sliding of the corner protector 110 relative to the slide block 120 can be released.

[0035] In one possible implementation, the fully automatic corner protection device 100 for the display screen further includes a second elastic element 160. The second elastic element 160 is sleeved on the column body 142, and its two ends abut against the snap-fit ​​connector 141 and the first insertion hole 123, respectively. In specific applications, in order to achieve the elastic snap-fit ​​of the top column 140 in the snap-fit ​​groove 1121, the second elastic element 160 is sleeved on the column body 142, and its two ends abut against the snap-fit ​​connector 141 and the first insertion hole 123, respectively. The first insertion hole 123 is a stepped hole 112, and the second elastic element 160 is a compression spring. One end of the second elastic element 160 abuts against the snap-fit ​​connector 141, and the other end abuts against the step of the first insertion hole 123, thereby causing the snap-fit ​​connector 141 to be elastically abutted against in the snap-fit ​​groove 1121.

[0036] In one possible implementation, the fully automatic corner protection device 100 for the display screen further includes a second connecting post 170, a connecting portion 122 forming a third insertion hole 1221, the second connecting post 170 being inserted into the third insertion hole 1221, and a first elastic member 130 being elastically connected to the second connecting post 170 and the first connecting post 150. In specific applications, in order to connect the first elastic element 130 with the sliding part 111 and the connecting part 122, a third insertion hole 1221 is formed on the connecting part 122, and the second connecting post 170 is inserted into the third insertion hole 1221. The first elastic element 130 is a tension spring, which is elastically connected between the second connecting post 170 and the first connecting post 150, so that the corner protector 110 is reset and slid on the slide block 120. It is worth noting that at least two sliding parts 111 are symmetrically arranged on the upper and lower symmetrical sides of the corner protector 110, and at least two connecting parts 122 are symmetrically arranged on the upper and lower symmetrical sides of the slide block 120. In order to enhance the stability of the connection, at least two first elastic elements 130 are connected to the sliding part 111 of the corner protector 110 and the connecting part 122 of the slide block 120.

[0037] In one possible implementation, the first connecting post 150 is provided with a first connecting groove 152, the second connecting post 170 is provided with a second connecting groove 171, and the two ends of the first elastic member 130 are respectively connected to the first connecting groove 152 and the second connecting groove 171. In specific applications, in order to prevent the first elastic member 130 from accidentally detaching when connected to the first connecting post 150 and the second connecting post 170, the two ends of the first elastic member 130 are respectively connected to the first connecting groove 152 and the second connecting groove 171.

[0038] In one possible implementation, when splicing the displays, the two opposing top posts 140 abut against each other, causing the top posts 140 to disengage from the stepped holes 112 and releasing the restriction on the sliding of the corner protectors 110 relative to the sliding groove holes 121. In specific applications, during the splicing process, the top post 140 of the first display abuts against the top post 140 of the other display, thereby releasing the restriction on the sliding of the corner protectors 110 relative to the sliding groove holes 121. This allows the corner protectors to retract into the slide base 120, thus quickly completing the assembly of the displays and improving the efficiency of display installation. Furthermore, after disassembling the displays, the corner protectors 110 can be spread apart relative to the slide base 120 to protect the displays.

[0039] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
