Description

Technical Field

[0001] This utility model relates to a sleeve packaging box, belonging to the field of sleeve packaging technology. Background Technology

[0002] Traditional wooden crate packaging has significant drawbacks in the transportation and storage of low-voltage, high-current bushings: in terms of protection, the crate structure is not strong enough, making the bushings easily damaged during transportation; in terms of adaptability, the wooden crate design is not optimized for the weight distribution and special shape of high-current bushings, resulting in poor fixation and easy displacement of the bushings; in terms of ease of operation, the complex wooden crate structure makes the loading and unloading process cumbersome, seriously affecting the efficiency of logistics operations. Utility Model Content

[0003] The purpose of this utility model is to provide a bushing packaging box that ensures high-strength protective performance while achieving precise compatibility with low-voltage, high-current bushings; the loading and unloading process is convenient, significantly improving operational convenience, thereby comprehensively improving the reliability and economy of low-voltage, high-current bushing transportation and storage.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A sleeve packaging box includes a supporting part, an outer covering part covering the supporting part, and a plurality of latches for fixing the supporting part and the outer covering part; The load-bearing part includes a base plate, with multiple support plates evenly and parallelly arranged below the base plate, and a square frame above the base plate. The top of the square frame has several fixing holes corresponding to the flange holes on the sleeve flange. On the corresponding two sides of the square frame, sealing plates are installed, and the two ends of the sealing plates extend outside the frame. The outer casing includes a square cover with an open bottom that corresponds to the square frame. Two side panels of the square cover extend downward and are inserted into the gap formed between the ends of the two end plates and the square frame. The fixed part of the latch is installed at the end of the sealing plate, and the movable part of the latch is installed on the side plate inside the insertion gap. The fixed part and the movable part of the latch are correspondingly set and connected by a snap-fit. The side columns of the square frame perpendicular to the sealing plate extend outward, and corresponding through holes are opened at the ends of the two side columns at the top and bottom. A screw rod is installed on the square frame and inserted vertically through the through hole, and the screw rod is fixed to the square frame by a nut.

[0005] Preferably, multiple reinforcing strips are provided inside the side frame of the square frame.

[0006] Preferably, the reinforcing strip includes a vertically arranged longitudinal column whose top and bottom both abut against the inner wall of the side frame, and two inclined columns arranged on both sides of the longitudinal column, one end of which abuts against the top plate and side wall of the side frame, and the other end of which abuts against the longitudinal strip and the bottom plate of the side frame.

[0007] The beneficial effects of this utility model are as follows: 1. The overall packaging frame is constructed by the load-bearing part and the outer covering part on the load-bearing part. Combined with the rigid connection design between the screw and the load-bearing part, high-strength protection is achieved, and transportation losses are significantly reduced.

[0008] 2. The top of the square frame is precisely equipped with fixing holes according to the standard hole spacing of the low-voltage high-current bushing flange. Combined with bolts and other connecting parts, the bushing is accurately positioned and firmly fixed, avoiding the shaking and displacement caused by insecure fixing. This allows the low-voltage high-current bushing to be stably installed on the load-bearing part, improving transportation safety.

[0009] 3. The snap-lock system requires no tools. Operators can quickly connect or disconnect the load-bearing part and the outer packaging part by simply pressing and pulling. The loading and unloading process is greatly simplified, and the efficiency of loading and unloading is significantly improved compared with traditional wooden crates, which shortens the logistics operation time and improves the overall operational efficiency.

[0012] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0013] This embodiment provides a sleeve packaging box, such as Figure 1-5 As shown, it includes a support part 1, an outer covering part 2 covering the support part 1, and a plurality of latches 3 for fixing the support part 1 and the outer covering part 2.

[0014] The support unit 1 includes a base plate 4, with multiple support plates 5 evenly and parallelly arranged below the base plate 4. A square frame 6 is positioned above the base plate 4, and the top of the square frame 6 has several fixing holes 7 corresponding to the flange holes on the bushing flange. The low-voltage, high-current bushing is placed on the support unit 1, with the flange of the low-voltage, high-current bushing abutting against the top of the square frame 6. The orientation of the low-voltage, high-current bushing is adjusted so that the flange holes on its flange align with the fixing holes 7, and then it is fixed using bolt assemblies. Sealing plates 8 are installed on the corresponding two outer sides of the square frame 6, with both ends of the sealing plates 8 extending outside the frame. This structure creates a longitudinal, insertable gap between the corresponding ends of the two sealing plates 8 and the square frame 6.

[0015] The outer casing 2 includes a square cover 9 with an open bottom that corresponds to the square frame. Two side plates of the square cover 9 extend downward and are inserted into the gap formed between the ends of the two sealing plates 8 and the square frame. During assembly, the two downwardly extending side plates of the square cover 9 are inserted into the longitudinal insertable gap formed between the ends of the sealing plates 8 and the square frame 6. In this way, the square cover 9 will cover the upper half of the low-voltage high-current bushing, and the non-downward extending side plates will abut against the top of the square frame 6.

[0016] The fixing part 11 of the latch 3 is installed at the end of the sealing plate 8, and the movable part 10 of the latch 3 is installed on the side plate in the insertion gap. The fixing part 11 and the movable part 10 of the latch 3 are correspondingly arranged and connected by a snap-fit; that is, the latch 3 is a snap-fit ​​structure, which is an existing connector, and its structure will not be described in detail here.

[0017] To improve overall strength, the side posts of the square frame 6, perpendicular to the sealing plate 8, extend outward, and corresponding through holes are provided at the ends of the two side posts at the top and bottom. Vertical threaded rods 12 are installed on the square frame 6, passing through the through holes, and are fixed to the square frame 6 with nuts. Meanwhile, multiple reinforcing bars are provided inside the side frame of the square frame 6. The reinforcing bars include vertically arranged longitudinal posts 13 whose top and bottom abut against the inner wall of the side frame, and two diagonal posts 14 arranged on both sides of the longitudinal posts 13, one end abutting against the top plate and side wall of the side frame, and the other end abutting against the longitudinal post and the bottom plate 4 of the side frame.

[0018] In practical applications, the square frame 6, the square cover 9, and the sealing plate 8 are all made of wood.

[0019] The above description is only a preferred embodiment of this utility model patent. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model patent, and these improvements and modifications should also be considered within the scope of protection of this utility model patent.
