Description

Technical Field

[0001] This utility model relates to the field of die-casting box technology, specifically to a die-casting box with stable splicing. Background Technology

[0002] Die-cast boxes are structures used to support displays such as LED panels. They not only make the display easier to move and install, but also make the display look more aesthetically pleasing. In some situations where large screens are required, multiple displays are often spliced ​​together, which necessitates a stable die-cast box.

[0003] According to a public notice (Announcement No.: CN218705166U) of a magnesium alloy die-casting box, the aforementioned application uses a hook-and-lock mechanism to secure the magnesium alloy die-casting box to the hook-and-lock pin, preventing the magnesium alloy die-casting box from falling off during hook-and-locking. The hook-and-lock pin can be rotated and locked to the hook-and-lock hole of another magnesium alloy die-casting box, ensuring the stability of the assembly between magnesium alloy die-casting boxes, preventing the assembled magnesium alloy die-casting boxes from detaching, and ensuring the safety of the magnesium alloy die-casting box in use.

[0004] However, in actual use, the above-mentioned equipment relies solely on rotating the irregular nut for locking, which is insufficient for the connection strength between the die-casting boxes. When the die-casting boxes need to be used in the external environment, they are easily subjected to various vibrations. Vibrations may cause the irregular nut to rotate, thereby causing the irregular nut to detach from the insertion hole and resulting in the die-casting box becoming loose. In view of this, we propose a die-casting box with stable splicing. Utility Model Content

[0005] The purpose of this invention is to provide a stable die-casting box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable die-casting box, comprising a box body, wherein fixing holes are provided on the outer walls of the box body, a wire storage box is fixedly connected to the inner wall of the box body, and a splicing assembly is provided inside the box body, the splicing assembly comprising:

[0007] A connecting plate is rotatably connected to the inner wall of the box. Both ends of the outer wall of the connecting plate are fixedly connected to clamps. Bolts are threaded through the outer wall of the clamps. A rotating plate is rotatably connected to the outer wall of the clamps away from the connection between the connecting plate and the box.

[0008] A spring rod is rotatably connected to the inner wall of the clamping plate. The spring rod passes through the clamping plate and is fixedly connected to the rotating plate. A top plate is fixedly connected to the end of the spring rod away from the clamping plate. A top block is slidably connected to the end of the clamping plate away from the rotating plate. A return spring is fixedly connected to the outer wall of the top block. A limit plate is fixedly connected to the inner wall of the box.

[0009] The interior of the box is equipped with a storage component, which includes a locking block. The locking block is fixedly connected to the outer wall of the connecting plate. Locking grooves are provided at both ends of the locking block. The inner wall of the box is provided with a slot, and a triangular telescopic block is fixedly connected to the inner wall of the slot.

[0010] Preferably, the size of the slot matches the size of the block, the block engages with the slot, and the size of the locking groove is consistent with the output end size of the triangular telescopic block. The locking groove engages with the triangular telescopic block. When the connecting plate is rotated, the block on the connecting plate engages with the slot. The triangular telescopic block retracts upon contact with the block. When the connecting plate is rotated until the locking groove is directly opposite the triangular telescopic block, the triangular telescopic block extends and engages with the locking groove, thus fixing the connecting plate to the inner wall of the housing.

[0011] Preferably, the enclosure is fixedly connected to the four sides of the box, and the fixing holes are opened on the enclosure. The LED board can be fixed to the die-casting box through the fixing holes. The distance between the two sets of clamps on the outer wall of the connecting plate is twice the width of the enclosure. When two die-casting boxes need to be spliced, the connecting plate can be rotated towards the other die-casting box. At this time, the clamps can clamp the two enclosures and make the enclosures fit together.

[0012] Preferably, the inner wall of the clamping plate has a rotating groove, the top plate is rotatably connected to the inner wall of the rotating groove, the outer wall of the clamping plate has a through top groove, the top block is slidably connected to the inner wall of the top groove, and the rotating groove and the top groove are interconnected. The surrounding plate has a snap-fit ​​groove that matches the top block, and the top block is slidably connected to the inner wall of the snap-fit ​​groove. When the rotating plate is rotated, the rotating plate drives the spring rod to rotate, causing the top plate to rotate in the rotating groove and contact the top block, thereby lifting the top block and allowing the top block to snap into the snap-fit ​​groove, thus preventing the connecting plate from moving.

[0013] Preferably, the top plate and the rotating plate are perpendicular to each other. The number of limiting plates is set to eight sets, with two sets forming a pair. The four pairs of limiting plates are distributed in a rectangular array on the inner wall of the box. The distance between each pair of limiting plates is the same as the width of the rotating plate. When the connecting plate rotates, the rotating plate contacts the limiting plates, and the gap between the limiting plates causes the rotating plate to rotate, making the rotating plate and the limiting plates slide together. The rotating plate is perpendicular to the top plate. At this time, the top plate rotates to the position that lifts the top block, and the rotating plate is limited by the limiting plates and cannot rotate.

[0014] Preferably, the length of the bolt is greater than twice the sum of the width of the surrounding plate and the width of the clamping plate, and both the surrounding plate and the clamping plate are provided with through threaded grooves. The bolt is threadedly connected to the threaded grooves, so that the bolt can fix the two sets of die-casting boxes and connecting plates to be spliced ​​together, making the die-casting boxes less likely to loosen.

[0015] Compared with the prior art, this utility model provides a stable die-casting box with the following features:

[0016] Beneficial effects:

[0017] 1. This stable die-casting box allows for easy assembly of two die-casting boxes. To join two boxes, rotate the connecting plate on one box to the other, align the gap between the limiting plates on the other box with the rotating plate, and then push the box in. This aligns the two boxes and allows them to fit together. Insert and tighten the bolts to secure the boxes. The rotating plate, driven by the limiting plates, rotates, causing the spring rod to rotate the top plate, lifting the top block and engaging it with the locking groove. This ensures a more secure and less prone-to-loosening connection between the die-casting boxes. Even if the bolts loosen due to external influences, the connecting plate will still hold the two boxes in place, guaranteeing safe use.

[0018] 2. This stable die-cast box does not require a connecting plate for fixing. It can rotate to make the locking block on the connecting plate engage with the locking slot. The triangular telescopic block retracts when it contacts the locking block. When the connecting plate rotates to the locking slot facing the triangular telescopic block, the triangular telescopic block extends and engages with the locking slot, so that the connecting plate is fixed to the inner wall of the box and prevents the connecting plate from rotating at will and causing the wires connecting the LED board of the wire storage box to become loose.

Detailed Implementation

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a stable die-casting box, including a box body 1, with fixing holes 2 on the outer wall of the edge of the box body 1, a wire storage box 3 fixedly connected to the inner wall of the box body 1, and a splicing assembly 4 inside the box body 1, the splicing assembly 4 including a connecting plate 41, a clamping plate 42, a bolt 43, a rotating plate 44, a spring rod 45, a top plate 46, a top block 47, a reset spring 48, and a limiting plate 49.

[0026] In one embodiment of the present invention, the connecting plate 41 is rotatably connected to the inner wall of the box 1, and the two ends of the outer wall of the connecting plate 41 are fixedly connected to the clamping plate 42. The outer wall of the clamping plate 42 is threaded with bolts 43, and the outer wall of the clamping plate 42 away from the connection between the connecting plate 41 and the box 1 is rotatably connected to the rotating plate 44.

[0027] In one embodiment of this utility model, a spring rod 45 is rotatably connected to the inner wall of a clamping plate 42, the spring rod 45 passes through the clamping plate 42 and is fixedly connected to a rotating plate 44, a top plate 46 is fixedly connected to the end of the spring rod 45 away from the clamping plate 42, a top block 47 is slidably connected to the end of the clamping plate 42 away from the rotating plate 44, a reset spring 48 is fixedly connected to the outer wall of the top block 47, and a limit plate 49 is fixedly connected to the inner wall of the housing 1.

[0028] In one embodiment of this utility model, the interior of the box 1 is provided with a storage component 5, which includes a locking block 51. The locking block 51 is fixedly connected to the outer wall of the connecting plate 41. Locking grooves 52 are provided at both ends of the locking block 51. The inner wall of the box 1 is provided with a slot 53. A triangular telescopic block 54 is fixedly connected to the inner wall of the slot 53.

[0029] In addition, the size of the slot 53 matches the size of the block 51, and the block 51 engages with the slot 53. The size of the locking groove 52 is the same as the output end size of the triangular telescopic block 54, and the locking groove 52 engages with the triangular telescopic block 54. When the connecting plate 41 is rotated, the block 51 on the connecting plate 41 engages with the slot 53. The triangular telescopic block 54 retracts when it contacts the block 51. When the connecting plate 41 is rotated so that the locking groove 52 is directly opposite the triangular telescopic block 54, the triangular telescopic block 54 extends and engages with the locking groove 52, so that the connecting plate 41 is fixed on the inner wall of the box 1, preventing the connecting plate 41 from rotating arbitrarily and causing the wires connecting the LED board of the wire storage box 3 to become loose.

[0030] In this embodiment of the utility model, the box body 1 is fixedly connected with a surrounding plate, and the fixing hole 2 is opened on the surrounding plate. The LED board can be fixed on the die-casting box through the fixing hole 2. The distance between the two sets of clamping plates 42 on the outer wall of the connecting plate 41 is twice the width of the surrounding plate. When two die-casting boxes need to be spliced, the connecting plate 41 is rotated towards the other die-casting box. At this time, the clamping plate 42 can clamp the two surrounding plates and make the surrounding plates fit together, thereby making the LED board fit together and making the splicing effect of the LED board better.

[0031] In this embodiment of the utility model, the inner wall of the clamping plate 42 is provided with a rotating groove, the top plate 46 is rotatably connected to the inner wall of the rotating groove, the outer wall of the clamping plate 42 is provided with a through top groove, the top block 47 is slidably connected to the inner wall of the top groove, and the rotating groove and the top groove are interconnected. The surrounding plate is provided with a snap-fit ​​groove that matches the top block 47, and the top block 47 is slidably connected to the inner wall of the snap-fit ​​groove. When the rotating plate 44 is rotated, the rotating plate 44 drives the spring rod 45 to rotate, causing the top plate 46 to rotate in the rotating groove and contact the top block 47, thereby lifting the top block 47 by the top plate 46, so that the top block 47 can snap into the snap-fit ​​groove, thereby preventing the connecting plate 41 from moving and allowing the die-casting box to fit tightly together.

[0032] In this embodiment of the utility model, the top plate 46 and the rotating plate 44 are perpendicular to each other. There are eight sets of limiting plates 49, with two sets forming a pair. The four pairs of limiting plates 49 are distributed in a rectangular array on the inner wall of the box 1. The distance between each pair of limiting plates 49 is the same as the width of the rotating plate 44. When the connecting plate 41 rotates, the rotating plate 44 contacts the limiting plates 49, and the gap between the limiting plates 49 causes the rotating plate 44 to rotate, so that the rotating plate 44 and the limiting plates 49 are slidably connected. The rotating plate 44 is perpendicular to the top plate 46. At this time, the top plate 46 rotates to the position that lifts the top block 47, and the rotating plate 44 is limited by the limiting plates 49 and cannot rotate, so that the top block 47 can be kept in the state of being engaged with the locking groove, thereby making it difficult for the spliced ​​die-casting box to loosen.

[0033] In an embodiment of this utility model, the length of the bolt 43 is greater than twice the sum of the width of the surrounding plate and the width of the clamping plate 42, and both the surrounding plate and the clamping plate 42 are provided with through threaded grooves. The bolt 43 is threadedly connected to the threaded grooves, so that the bolt 43 can fix the two sets of die-casting boxes and the connecting plate 41 to be spliced ​​together, making the die-casting boxes less likely to loosen.

[0034] In this invention, when two die-casting boxes need to be joined together, first, the connecting plate 41 on one die-casting box is rotated to the other die-casting box, aligning the gap between the limiting plates 49 on the other die-casting box with the rotating plate 44, and then the die-casting box is pushed in. At this point, the two die-casting boxes are not only aligned but also tightly fitted together. Bolts 43 can then be inserted and tightened to fix the die-casting box and connecting plate 41 together. The rotating plate 44 rotates under the influence of the limiting plates 49. When the rotating plate 44 rotates, the spring rod 45 drives the top plate 46 to rotate, causing the top block 47 to be lifted, thus engaging the top block 47 with the locking groove. This ensures that even when the bolts 43 loosen, the connecting plate 41 can still fix the two die-casting boxes, making the fixation between the die-casting boxes more secure and less prone to loosening. Then, the LED board is fixed to the die-casting box through the fixing hole 2 and the wire storage box 3, allowing multiple LED boards to be joined together to form a large screen effect. The connecting plate 41, which is not needed for fixing, can be rotated. The movement causes the locking block 51 on the connecting plate 41 to engage with the locking groove 53. The triangular telescopic block 54 retracts upon contact with the locking block 51. When the connecting plate 41 rotates to the position where the locking groove 52 is directly opposite the triangular telescopic block 54, the triangular telescopic block 54 extends and engages with the locking groove 52, thus fixing the connecting plate 41 to the inner wall of the housing 1. This prevents the connecting plate 41 from rotating arbitrarily and causing the wires connecting the LED board to the wire storage box 3 to become loose. At this point, the LED board is fixed to the die-casting box through the fixing hole 2 and the wire storage box 3, allowing multiple LED boards to be spliced ​​together to form a large screen effect. To disassemble the splicing, the LED board is removed, the bolt 43 is loosened and pulled out, and the rotating plate 44 is pulled up, causing the spring rod 45 to extend and thus disengage the rotating plate 44 from the limiting plate 49. The rotating plate 44 is then rotated so that the top plate 46 leaves the top block 47. The top block 47 leaves the locking groove under the action of the return spring 48, allowing the connecting plate 41 to rotate again and disengage the die-casting boxes.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
