Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and more specifically, to an LED cabinet and an LED display device having the same. Background Technology

[0002] LED display devices are flat panel displays composed of small LED cabinets. The front of each LED cabinet has an LED light panel. It is a display method that controls light-emitting diodes. Roughly speaking, it consists of many light-emitting diodes, usually of the three primary colors R, G, and B. It is used to display various information such as text, images, video, and recorded signals. LED display devices have advantages such as high brightness, low operating voltage, low power consumption, miniaturization, easy matching with integrated circuits, simple driving, long life, impact resistance, and stable performance.

[0003] However, for vertically installed LED display devices, LED cabinets need to be stacked vertically to form a larger display screen. Connecting structures are required between adjacent LED cabinets to splice them together. Typically, one worker needs to lift the LED cabinet to the appropriate position while another worker operates the connecting structure to lock the adjacent LED cabinets together. This loading and unloading operation is quite cumbersome, resulting in low work efficiency for the workers. Utility Model Content

[0004] The main objective of this invention is to provide an LED cabinet and an LED display device having the same, so as to solve the problem that the splicing operation of LED cabinets in related technologies is relatively troublesome.

[0005] To achieve the above objectives, according to one aspect of the present invention, an LED enclosure is provided, comprising: a mounting frame; a light panel disposed on the front side of the mounting frame; a lock seat disposed on the lower part of the mounting frame; a locking pin movably disposed on the upper part of the mounting frame and adapted to the lock seat, the locking pin having an extended position and a retracted position, wherein when the locking pin is in the extended position, the locking pin extends upward beyond the mounting frame and can extend into the lock seat so that the locking pin can lock into the lock seat; when the locking pin is in the retracted position, the locking pin is within the range of the mounting frame; a handle extending vertically and connected to the mounting frame, the handle being located below the locking pin; and a trigger movably disposed vertically through the handle, wherein when the trigger moves upward, it drives the locking pin to move upward so that the locking pin switches from the retracted position to the extended position.

[0006] Furthermore, the mounting frame includes a enclosure and a vertical reinforcing beam disposed on the enclosure. The vertical reinforcing beam has a handle notch to form a handle portion, and the trigger end of the trigger element is located within the handle notch.

[0007] Furthermore, the vertical reinforcing beam is also provided with an installation notch located above the handle notch, with part of the locking pin located within the installation notch. The triggering element includes a trigger rod that is movable in the vertical direction. The lower end of the trigger rod forms a trigger end and is located within the handle notch, while the upper end of the trigger rod forms an abutment end and can push the locking pin to move the locking pin upward.

[0008] Furthermore, the upper end of the locking pin is provided with a latch, and the lock seat includes a movably disposed locking member. The locking member has a locked position and an unlocked position. When the locking member is in the locked position, the locking member engages with the latch to lock the locking pin with the lock seat. When the locking member is in the unlocked position, the locking member disengages from the latch to allow the locking pin to be disengaged from the lock seat.

[0009] Furthermore, the lock base also includes a base body, and the locking element includes a locking plate movably disposed on the base body in the lateral direction. The locking plate has a through hole, and a locking pin can pass through the through hole. The through hole has a large diameter section and a small diameter section. When the locking element is in the unlocked position, the large diameter section is correspondingly disposed with the locking pin, and the locking pin can slide within the large diameter section. When the locking element is in the locked position, the small diameter section is correspondingly disposed with the locking pin, and the portion of the locking plate corresponding to the small diameter section is engaged with the latch so that the locking pin and the lock base are locked together.

[0010] Furthermore, the lock seat also includes a first elastic element that applies an elastic force to the locking plate to keep the locking element in the locked position.

[0011] Furthermore, the lock seat also includes a second elastic member and a movably disposed retaining block. The retaining block has a stop position and a clearance position. When the retaining block is in the stop position, the retaining block is inserted into the large diameter section so that the locking member is kept in the unlock position. When the retaining block is in the clearance position, the retaining block is separated from the large diameter section, and the locking member is kept in the locked position under the action of the first elastic member. The second elastic member abuts against the retaining block so that the retaining block is kept in the stop position. When the locking pin moves upward, the locking pin can push the retaining block and switch the retaining block from the stop position to the clearance position.

[0012] Furthermore, the LED housing also includes a locking handle, which is threaded to the lower end of the locking pin. The trigger can push the locking pin upward by abutting the locking handle. When the small diameter section is set to correspond with the locking pin, the locking handle rotates to drive the locking pin downward, so that the upper limit of the locking plate in the vertical direction is located between the upper side wall of the bayonet and the bottom wall of the base body.

[0013] Furthermore, the LED enclosure also includes a mounting base, a locking pin passing through the mounting base and having a guide groove extending in a vertical direction, a protrusion on the mounting base, the protrusion being slidably disposed within the guide groove, the protrusion being able to engage with a side wall stop of the guide groove to prevent the locking pin from dislodging from the mounting base; and / or, the LED enclosure also includes a third elastic member, the third elastic member applying a downward force to the locking pin to keep the locking pin in the retracted position.

[0014] According to another aspect of the present invention, an LED display device is provided, comprising a plurality of LED cabinets, wherein the LED cabinets are as described above, wherein the plurality of LED cabinets include a first LED cabinet and a second LED cabinet located below the first LED cabinet, and the locking seat of the first LED cabinet can be locked and engaged with the locking pin of the second LED cabinet to connect the first LED cabinet and the first LED cabinet.

[0015] Applying the technical solution of this utility model, the mounting frame provides a mounting base for various components. The light panel is located on the front side of the mounting frame and is used for displaying images. The lock seat is located at the lower part of the mounting frame. The locking pin is movably located on the upper part of the mounting frame and is adapted to the lock seat. When facing the situation of splicing LED cabinets arranged vertically, adjacent LED cabinets are connected by cooperating the locking pin of one LED cabinet with the lock seat of another LED cabinet. Specifically, the locking pin has an extended position and a retracted position. When the locking pin is in the extended position, it extends upward from the mounting frame and can be inserted into the lock seat so that the locking pin can lock and cooperate with the lock seat, thereby connecting the adjacent LED cabinets. When the locking pin is in the retracted position... In the retracted position, the locking pin is located within the mounting frame to prevent interference between the locking pin and other structures when the LED cabinet is not assembled. The handle extends vertically and connects to the mounting frame, allowing workers to easily move and lift the LED cabinet. The handle is located below the locking pin. A trigger is movably inserted vertically through the handle. When the trigger moves upward, it moves the locking pin upward, switching it from the retracted position to the extended position. Workers can trigger the trigger by gripping the handle, causing the locking pin to move upward and thus switching its position. This simplifies the LED cabinet assembly process and avoids requiring multiple people to assemble the LED cabinet. Therefore, the technical solution of this application effectively solves the problem of cumbersome LED cabinet assembly operations in related technologies. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] like Figures 1 to 4 As shown, this application provides an LED enclosure. An embodiment of the LED enclosure includes: a mounting frame 10, a lamp panel, a lock base 20, a locking pin 30, a handle 40, and a trigger 50. The lamp panel is disposed on the front side of the mounting frame 10; the lock base 20 is disposed on the lower part of the mounting frame 10; the locking pin 30 is movably disposed on the upper part of the mounting frame 10 and adapted to the lock base 20. The locking pin 30 has an extended position and a retracted position. When the locking pin 30 is in the extended position, the locking pin 30 extends upwards. The mounting frame 10 is designed to extend into the lock seat 20 so that the locking pin 30 can lock into the lock seat 20. When the locking pin 30 is in the retracted position, it is within the range of the mounting frame 10. The handle 40 extends vertically and is connected to the mounting frame 10. The handle 40 is located below the locking pin 30. The trigger 50 is movably inserted through the handle 40 in the vertical direction. When the trigger 50 moves upward, it drives the locking pin 30 to move upward so that the locking pin 30 switches from the retracted position to the extended position.

[0033] Applying the technical solution of this embodiment, the mounting frame 10 provides a mounting base for each component. The light panel is located on the front side of the mounting frame 10 and is used to display the image. The lock seat 20 is located at the lower part of the mounting frame 10. The locking pin 30 is movably located on the upper part of the mounting frame 10 and is adapted to the lock seat 20. When facing the situation of splicing LED cabinets arranged vertically, adjacent LED cabinets are connected by cooperating the locking pin 30 of one LED cabinet with the lock seat 20 of another LED cabinet. Specifically, the locking pin 30 has an extended position and a retracted position. When the locking pin 30 is in the extended position, the locking pin 30 extends upward from the mounting frame 10 and can extend into the lock seat 20 so that the locking pin 30 can lock and cooperate with the lock seat 20, thereby connecting the adjacent LED cabinets. When the locking pin 30 is in the retracted position, the locking pin 30 extends upward from the mounting frame 10 and can extend into the lock seat 20 so that the locking pin 30 can lock and cooperate with the lock seat 20, thereby connecting the adjacent LED cabinets. In the retracted position, the locking pin 30 is located within the mounting frame 10 to prevent interference between the locking pin 30 and other structures when the LED cabinet is not assembled. The handle 40 extends vertically and connects to the mounting frame 10. The handle 40 allows workers to more easily move and lift the LED cabinet. The handle 40 is located below the locking pin 30. The trigger 50 is movably inserted vertically through the handle 40. When the trigger 50 moves upward, it causes the locking pin 30 to move upward, switching the locking pin 30 from the retracted position to the extended position. Workers can trigger the trigger 50 when they grasp the handle 40, thereby causing the locking pin 30 to move upward and switching its position. This simplifies the operation of connecting the LED cabinet and avoids the need for multiple people to connect the LED cabinet. Therefore, the technical solution of this embodiment can effectively solve the problem of the cumbersome assembly operation of LED cabinets in related technologies.

[0034] It should be noted that the hierarchical relationship mentioned in this article is only based on... Figure 1 The description of this embodiment uses the up and down direction, not an absolute up and down direction. For example, [the description may be in the context of] the vertical direction. Figure 1 After the vertical direction is reversed, the lock seat 20 and the lock pin 30 can be connected, thereby realizing the connection of the LED box.

[0035] like Figures 1 to 4 As shown, the mounting frame 10 includes a frame 11 and a vertical reinforcing beam 12 disposed on the frame 11. The vertical reinforcing beam 12 is provided with a handle notch 121 to form a handle portion 40, and the trigger end of the trigger member 50 is located within the handle notch 121. Specifically, by providing a handle notch 121 on the vertical reinforcing beam 12 to form the handle portion 40, it is unnecessary to provide a separate solid structure to form the handle portion, thus avoiding excessive weight of the LED cabinet.

[0036] like Figures 1 to 4As shown, the vertical reinforcing beam 12 is also provided with a mounting notch 122 located above the handle notch 121. Part of the locking pin 30 is located within the mounting notch 122. The trigger 50 includes a trigger rod 51 that is movable in the vertical direction. The lower end of the trigger rod 51 forms a trigger end and is located within the handle notch 121. The upper end of the trigger rod 51 forms an abutment end and can push the locking pin 30 to move the locking pin 30 upward. Specifically, the mounting notch 122 is used to accommodate part of the locking pin 30 and part of the trigger rod 51. The operator's hand pushes the trigger end of the trigger rod 51 upward, thereby causing the trigger rod 51 to move upward and driving the locking pin 30 upward, thus realizing the position switching of the locking pin 30. The trigger rod 51 has the advantage of simple structure, and the trigger rod 51 passes through part of the vertical reinforcing beam 12 between the mounting notch 122 and the handle notch 121, thereby guiding the trigger rod 51.

[0037] like Figures 1 to 6 As shown, the upper end of the locking pin 30 is provided with a latch 31, and the lock base 20 includes a movably disposed locking member 21. The locking member 21 has a locked position and an unlocked position. When the locking member 21 is in the locked position, it engages with the latch 31 to lock the locking pin 30 and the lock base 20. When the locking member 21 is in the unlocked position, it disengages from the latch 31 to allow the locking pin 30 to disengage from the lock base 20. Specifically, the locking member 21 and the latch 31 enable the connection or separation of the locking pin 30 and the lock base 20.

[0038] like Figure 5 as well as Figure 6As shown, the lock base 20 also includes a base body 22. The locking member 21 includes a locking plate 211 movably disposed on the base body 22 in the lateral direction. The locking plate 211 has a through hole 212, through which the locking pin 30 can pass. The through hole 212 has a large diameter section 2121 and a small diameter section 2122. When the locking member 21 is in the unlocked position, the large diameter section 2121 is correspondingly disposed with the locking pin 30, and the locking pin 30 can slide within the large diameter section 2121. When the locking member 21 is in the locked position, the small diameter section 2122 is correspondingly disposed with the locking pin 30, and the portion of the locking plate 211 corresponding to the small diameter section 2122 is engaged with the slot 31 to lock the locking pin 30 and the lock base 20. Specifically, the bayonet 31 is an annular groove, with the large-diameter section 2121 and the small-diameter section 2122 interconnected. The size of the large-diameter section 2121 is larger than that of the small-diameter section 2122. The size of the large-diameter section 2121 matches the size of the locking pin 30, allowing the locking pin 30 to slide within the large-diameter section 2121. Because the size of the large-diameter section 2121 is larger than that of the locking pin 30 at the bayonet 31, the portion of the locking plate 211 corresponding to the small-diameter section 2122 can engage with the bayonet 31. Furthermore, in this embodiment, the lock base 20 also includes a first elastic element, which applies an elastic force to the locking plate 211 to keep the locking member 21 in the locked position. The first elastic element is a compression spring.

[0039] like Figure 5 as well as Figure 6 As shown, the lock base 20 also includes a second elastic member 23 and a movably disposed retaining block 24. The retaining block 24 has a stop position and a clearance position. When the retaining block 24 is in the stop position, the retaining block 24 is inserted into the large diameter section 2121 so that the locking member 21 is kept in the unlock position. When the retaining block 24 is in the clearance position, the retaining block 24 is separated from the large diameter section 2121. The locking member 21 is kept in the locked position under the action of the first elastic member. The second elastic member 23 abuts against the retaining block 24 so that the retaining block 24 is kept in the stop position. When the locking pin 30 moves upward, the locking pin 30 can push the retaining block 24 and switch the retaining block 24 from the stop position to the clearance position. Specifically, when the locking pin 30 is withdrawn from the lock seat 20, the retaining block 24, under the action of the second elastic member 23, enables the large diameter section 2121 to correspond with the locking pin 30, so that when the locking pin 30 is reinserted into the lock seat 20, the locking plate 211 will not stop the locking pin 30 due to the setting of the first elastic member, thus preventing the locking pin 30 from being inserted into the lock seat 20.

[0040] like Figure 1 as well as Figure 3As shown, the LED cabinet also includes a locking handle 60, which is threaded to the lower end of the locking pin 30. The trigger 50 can push the locking pin 30 upward by abutting the locking handle 60. When the small diameter section 2122 is correspondingly set with the locking pin 30, the locking handle 60 rotates and drives the locking pin 30 downward, so that the upper limit of the locking plate 211 in the vertical direction is located between the upper side wall of the bayonet 31 and the bottom wall of the base body 22. Specifically, when the locking pin 30 is inserted into the lock base 20, part of the locking plate 211 is engaged with the bayonet 31, so that the locking pin 30 will not come out of the lock base 20 in the vertical direction. However, since the vertical width of the bayonet 31 is larger than the thickness of the locking plate 211, the LED cabinet is prone to shifting. By setting the locking handle 60, the locking plate 211 can be limited in the vertical direction between the upper side wall of the bayonet 31 and the bottom wall of the base body 22, thereby locking the adjacent LED cabinets.

[0041] like Figure 1 as well as Figure 3 As shown, the LED cabinet also includes a mounting base 70. A locking pin 30 passes through the mounting base 70 and is provided with a guide groove 32 extending in the vertical direction. A protrusion is provided on the mounting base 70, which is slidably disposed within the guide groove 32. The protrusion can cooperate with the side wall stop of the guide groove 32 to prevent the locking pin 30 from coming out of the mounting base 70. Specifically, the guide groove 32 and the protrusion have the advantages of simple structure and stable cooperation.

[0042] In addition, the LED enclosure also includes a third elastic element that applies a downward force to the locking pin 30 so that the locking pin 30 is held in the retracted position, so that the locking pin 30 can remain within the retracted range of the mounting frame 10 when the LED enclosure is not spliced.

[0043] This application also provides an LED display device, which includes multiple LED cabinets, wherein the LED cabinets are as described above. The multiple LED cabinets include a first LED cabinet and a second LED cabinet located below the first LED cabinet. The locking seat 20 of the first LED cabinet can lock and cooperate with the locking pin 30 of the second LED cabinet to connect the first LED cabinet and the second LED cabinet. The above-mentioned LED cabinet can effectively solve the problem of the relatively cumbersome splicing operation of LED cabinets in related technologies, and the LED display device with the above-mentioned LED cabinet also has the above-mentioned advantages.
