A fall-preventing tool transportation packaging box with self-locking buckle

Abstract

This utility model discloses a drop-proof knife transport packaging box with a self-locking buckle, including a base, a tray, a packaging box body, and a linkage mechanism. The tray is placed on the base, the packaging box body is placed on the tray, and the linkage mechanism is located on the base and connected to the tray, with the linkage mechanism located on one side of the packaging box body. The beneficial effects of this utility model are: by setting up a linkage mechanism, the packaging box body drives the tray to move downwards. At the same time, the linkage mechanism drives the second protective rod to move in tandem through the linkage rod. At this time, the second protective rod drives the first protective rod to move synchronously through the first and second synchronizing rods, so that the first and second protective rods move together to the loading and unloading end of the packaging box body, forming a limiting and locking effect on the isolation door of the loading and unloading end of the packaging box body. The linkage is triggered by gravity sensing, eliminating the risk of human operation error, and is simple, efficient, practical, and reliable.

Description

Technical Field

[0001] This utility model relates to a knife transport packaging box, specifically a drop-proof knife transport packaging box with self-locking buckles, belonging to the technical field of knife transport packaging boxes. Background Technology

[0002] Cutting tools are tools used for cutting and machining in mechanical manufacturing. Most cutting tools are machine-made, but some are hand-made. Since cutting tools used in mechanical manufacturing are mainly used for cutting metal materials, the term "cutting tool" is generally understood as a metal cutting tool. Cutting tools used for cutting wood are called woodworking tools. There is also a special type of tool used for geological exploration, well drilling, and mining, which is called mining tool. Because cutting tools are generally quite sharp, they usually need to be stored in packaging boxes during transportation.

[0003] However, most existing knife transport packaging boxes have various problems. For example, in a chip packaging cutting knife packaging box disclosed in announcement number CN222224790U, although the push head, push rod, and push plate rebound upward through the elastic action of return spring two and return spring three, so that the lifting plate can automatically return to its original position and save the time of picking up the blade, in this technical solution and most current packaging boxes, for relatively large packaging boxes, the opening end is generally equipped with two double doors to facilitate the loading and unloading of the knife. After loading and unloading, the two doors need to be locked with components such as latches or bolts. However, during transportation, under the long-term vibration and bumps, the latches or bolts on the packaging box may loosen and fall off, causing the isolation door to open, which in turn causes the knife to fall and be damaged, which can easily cause certain economic losses and also poses a great safety hazard. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing a drop-proof knife transport packaging box with a self-locking buckle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drop-proof knife transport packaging box with self-locking buckle includes a base, a tray, a packaging box body and a linkage mechanism. The tray is set on the base, the packaging box body is placed on the tray, and the linkage mechanism is set on the base and connected to the tray. The linkage mechanism is located on one side of the packaging box body.

[0007] The linkage mechanism includes a support frame, a first protective rod, a second protective rod, and a linkage rod. The support frame is vertically fixed at the edge of the base. The first and second protective rods are rotatably connected to the support frame and are arranged in parallel. The first and second protective rods are located on the loading and unloading side of the packaging box body. One end of the linkage rod is rotatably connected to the second protective rod near the support frame, and the other end is rotatably connected to the pallet.

[0008] As a further embodiment of this utility model: the linkage mechanism further includes a first synchronizing rod and a second synchronizing rod, the two ends of the first synchronizing rod being rotatably connected to one end of the first protective rod and the second protective rod near the support frame, and the two ends of the second synchronizing rod being rotatably connected to the other end of the first protective rod and the second protective rod.

[0009] As a further embodiment of this utility model: a rotating rod is fixed on the support frame, the first protective rod and the second protective rod are rotatably connected to the rotating rod, and a torsion spring is sleeved on the outside of the rotating rod, one end of the torsion spring is fixed to the rotating rod, and the other end is fixed to the protective rod.

[0010] As a further improvement of this utility model, the linkage mechanism is provided in at least four sets in a symmetrical manner at the four corners of the base.

[0011] As a further improvement of this utility model: the tray is made of lightweight aluminum material to form a rectangular structure, and multiple rectangular through slots are provided through the tray.

[0012] As a further improvement of this utility model: the base is provided with a through groove with the same shape as the tray, and the length and width of the through groove are both greater than those of the tray.

[0013] The beneficial effects of this utility model are:

[0014] In this utility model, a linkage mechanism is set up, which drives the tray to move downward through the packaging box body. At the same time, the linkage rod in the linkage mechanism drives the second protective rod to move in tandem. At this time, the second protective rod drives the first protective rod to move in tandem through the first and second synchronizing rods, so that the first and second protective rods move together to the loading and unloading end of the packaging box body, forming a limiting and locking effect on the isolation door of the loading and unloading end of the packaging box body. The linkage is triggered by gravity sensing, eliminating the risk of human operation error. Moreover, the mechanical self-locking structure can maintain the locking force continuously in the bumpy environment. It is simple, efficient, practical and reliable. Attached Figure Description

[0020] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] like Figures 1 to 4 As shown, a drop-proof knife transport packaging box with self-locking buckle includes a base 1, a tray 2, a packaging box body 3 and a linkage mechanism 4. The tray 2 is set on the base 1, the packaging box body 3 is placed on the tray 2, and the linkage mechanism 4 is set on the base 1 and connected to the tray 2. The linkage mechanism 4 is located on one side of the packaging box body 3.

[0022] The linkage mechanism 4 includes a support frame 41, a first protective rod 42, a second protective rod 43, and a linkage rod 44. The support frame 41 is vertically fixed at the edge of the base 1. The first protective rod 42 and the second protective rod 43 are both rotatably connected to the support frame 41 and are arranged in parallel. The first protective rod 42 and the second protective rod 43 are located on the loading and unloading end side of the packaging box body 3. One end of the linkage rod 44 is rotatably connected to the second protective rod 43 near the support frame 41, and the other end is rotatably connected to the pallet 2.

[0023] The linkage mechanism 4 also includes a first synchronizing rod 45 and a second synchronizing rod 46. The two ends of the first synchronizing rod 45 are rotatably connected to the ends of the first protective rod 42 and the second protective rod 43 near the support frame 41, and the two ends of the second synchronizing rod 46 are rotatably connected to the other ends of the first protective rod 42 and the second protective rod 43.

[0024] A rotating rod 47 is fixed on the support frame 41. The first protective rod 42 and the second protective rod 43 are rotatably connected to the rotating rod 47. A torsion spring 48 is sleeved on the outside of the rotating rod 47. One end of the torsion spring 48 is fixed to the rotating rod 47, and the other end is fixed to the protective rod.

[0025] In this utility model, a linkage mechanism 4 is set up, which drives the tray 2 to move downward through the packaging box body 3. At the same time, the linkage rod 44 in the linkage mechanism 4 drives the second protective rod 43 to move in linkage. At this time, the second protective rod 43 drives the first protective rod 42 to move in linkage through the first synchronous rod 45 and the second synchronous rod 46, so that the first protective rod 42 and the second protective rod 43 move together to the loading and unloading end of the packaging box body 3, forming a limiting and locking effect on the isolation door of the loading and unloading end of the packaging box body 3. The linkage is triggered by gravity sensing, eliminating the risk of human operation error. Moreover, the mechanical self-locking structure can maintain the locking force continuously in the bumpy environment. It is simple, efficient, practical and reliable. Example 2

[0026] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0027] At least four sets of linkage mechanisms 4 are symmetrically arranged at the four corners of the base 1, forming a maximum protective effect on the packaging box body 3 through multiple sets of linkage mechanisms 4.

[0028] The tray 2 is made of lightweight aluminum and has a rectangular structure. Multiple rectangular slots are provided through the tray 2. The lightweight material and rectangular slots further reduce the weight of the tray 2, so that the tray 2 can quickly return to its original position by the elastic force of the torsion spring 48, and avoid its own weight from exceeding the elastic force of the torsion spring 48.

[0029] The base 1 has a through groove with the same shape as the tray 2, and the length and width of the through groove are larger than the tray 2. This allows the tray 2 to move into the base 1 when the packaging box body 3 presses the tray 2 to the bottom, so that the packaging box body 3 abuts against the base 1 and the tray 2 is not deformed.

[0030] Working principle: When using this tool to transport the packaging box, the packaging box body 3 is first hoisted onto the pallet 2 by the hoisting equipment. After adjusting the position, it is slowly lowered. During the descent, the linkage rod 44 drives the second protective rod 43 to move in tandem. At this time, the second protective rod 43 drives the first protective rod 42 to move in tandem through the first synchronous rod 45 and the second synchronous rod 46. This causes the first protective rod 42 and the second protective rod 43 to move together to the loading and unloading end of the packaging box body 3, thus forming a limiting and locking effect on the isolation door of the loading and unloading end of the packaging box body 3. After the transportation is completed, the packaging box body 3 is hoisted up. At this time, under the elastic force of the torsion spring 48, the pallet 2 is reset.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
