Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation equipment technology, specifically to a cargo carrier and locking structure used in transportation. Background Technology

[0002] In modern logistics and transportation, various goods may have different shapes and sizes, resulting in large gaps between different goods during transportation and low space utilization. Therefore, standardized cargo containers and their locking structures are the core foundation for achieving efficient and safe multimodal transport.

[0003] When existing cargo carriers are fixedly connected to the bottom of various equipment, intermediate twist locks are usually used to fix the bottom cargo carrier to the ship deck or other carrier placement surface.

[0004] When some cargo carriers are fixedly connected to the bottom of various equipment, the intermediate torsion lock can only fix a single corner piece on the bottom side of the carrier. At the same time, the operator needs to manually rotate the operating handle of the intermediate torsion lock, which increases the operator's burden. In addition, it can only be locked vertically. Therefore, we propose a cargo carrier and locking structure for transportation. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a cargo carrier and locking structure for transportation. Through the locking mechanism, the corner pieces between adjacent boxes on the left and right sides can be fixed simultaneously, and it can lock in both vertical and horizontal directions. This reduces the burden on operators while increasing horizontal locking, resulting in better fixing effect and effectively solving the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cargo carrier and locking structure for transportation, with a base plate on its upper surface having evenly distributed support seats fixedly connected to it. Each support seat has a box body on its upper side, and the upper and lower surfaces of the box body are fixedly connected to evenly distributed corner pieces. The left and right sides of the front surface of the box body are hinged with protective doors by hinges that are symmetrically distributed vertically and horizontally. Through the locking mechanism, the corner pieces between adjacent boxes on the left and right sides can be fixed simultaneously, and both vertical and horizontal locking can be performed, reducing the burden on operators while increasing horizontal locking and improving the fixing effect.

[0007] Furthermore, the front surface of the protective door is rotatably connected to symmetrically distributed rotating shafts, and the outer surface of each rotating shaft is rotatably connected to a handle. The upper and lower ends of the rotating shaft are fixedly connected to fixing plates. The upper and lower sides of the front surface of the box are fixedly connected to evenly distributed baffles. The fixing plates are all located inside the adjacent baffles on the same side to limit the movement of the protective door.

[0008] Furthermore, the front surface of the protective door is fixedly connected with evenly distributed fixing seats, and each fixing seat has a limit block rotatably connected to the upper side of its front surface. Each limit block has an installation hole inside, and each handle has a threaded hole inside to lock the handle.

[0009] Furthermore, it also includes an automatic lock, which is installed between two vertically adjacent boxes to connect the two vertically adjacent boxes.

[0010] This utility model also provides a locking structure for a cargo carrier box used in transportation. The locking mechanism includes a sliding block, a fixed rod, a rotating rod, and a locking block. The sliding blocks are all slidably connected to the inside of the support base. The lower end of each sliding block is fixedly connected to a fixed rod. Rotating rods are rotatably connected to the left and right sides inside the support base. Each rotating rod has a limit groove on its outer surface. The left and right ends of the fixed rod are slidably connected to adjacent limit grooves on the same side. The upper end of each rotating rod is fixedly connected to a locking block, which vertically locks the diagonal pieces and the support base.

[0011] Furthermore, the locking mechanism also includes a limiting rod, a connecting rod, and a pressing plate. The limiting rod is fixedly connected to the left and right surfaces of the sliding block, and the connecting rod is slidably connected to both the left and right sides inside the support base. A limiting groove is opened on the side of the connecting rod near the sliding block, and the end of the limiting rod away from the sliding block is slidably connected to the limiting groove on the same side. A pressing plate is fixedly connected to the side of the connecting rod away from the sliding block, thereby locking the diagonal piece and the support base laterally.

[0012] Furthermore, the locking mechanism also includes an adjusting bolt, which is threadedly connected to the upper inner side of the support base. The lower end of the adjusting bolt is rotatably connected to the upper surface of the sliding block to provide driving force.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This cargo carrier and locking structure for transportation has the following advantages:

[0014] The locking mechanism allows for the simultaneous fixing of the corner fittings between adjacent boxes on both the left and right sides, and enables locking in both vertical and horizontal directions. This reduces the workload for operators while increasing horizontal locking, resulting in better fixation. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-8 This embodiment provides a technical solution: a cargo carrier and locking structure for transportation, including a base plate 1;

[0026] Base plate 1: Its upper surface is fixedly connected with evenly distributed support seats 2, and each support seat 2 is provided with a box body 3. The upper and lower surfaces of the box body 3 are fixedly connected with evenly distributed corner pieces 4. The left and right sides of the front surface of the box body 3 are hinged with protective doors 10 through hinges 6 that are symmetrically distributed.

[0027] The front surface of the protective door 10 is rotatably connected to symmetrically distributed rotating shafts 7. A handle 8 is rotatably connected to the center of the outer surface of each rotating shaft 7. Fixed plates 11 are fixedly connected to the upper and lower ends of each rotating shaft 7. Evenly distributed baffles 12 are fixedly connected to the upper and lower sides of the front surface of the box body 3. The fixed plates 11 are all located inside adjacent baffles 12 on the same side. Evenly distributed fixed seats 13 are fixedly connected to the front surface of the protective door 10. Limit blocks 14 are rotatably connected to the upper surface of the front surface of each fixed seat 13. Each limit block 14 has an installation hole 15 inside. Each handle 8 has a threaded hole inside. When goods are placed inside the box body 1 and the protective door 10 is closed, the protective door 10 rotates around the central axis of the hinge shaft inside the hinge, causing the rear surface of the protective door 10 to contact the front surface of the box body 1. The movement of the protective door 10 moves the fixed plates 11, causing them to move inside the baffles 12. Figure 5 At this time, rotate the handle 8 to make the shaft 7 rotate, which will drive the fixing plate 11 to rotate around the central axis of the shaft 7, so that the fixing plate 11 is located behind the baffle 12. At this time, the rear surface of the handle 8 contacts the front surface of the fixing seat 13. Rotate the limiting block 14 so that the lower end of the limiting block 14 is close to the handle 8. At the same time, the mounting hole 15 is vertically aligned with the threaded hole inside the handle 8. Then, insert the bolt into the mounting hole 15 so that the lower end of the bolt is threadedly connected to the threaded hole inside the handle 8, thereby locking the handle 8 and thus locking the protective door 10.

[0028] It also includes an automatic lock 5, which is installed between two vertically adjacent containers 3. When the containers 3 need to be stacked, the automatic lock 5 can be inserted into the interior of the corner piece 4 on the lower surface of the upper container 3. The automatic lock 5 consists of an upper latching block and a lower locking tongue. The automatic lock 5 uses an automatic connector commonly used in the prior art for connecting vertically adjacent containers. After the latching block is inserted into the interior of the upper corner piece 4, the automatic lock 5 is rotated 90° so that the lower surface of the latching block contacts the lower interior surface of the upper corner piece 4. At this time, an external lifting device, such as a gantry crane, is used to connect the hook of the external lifting device to the upper container 3, thereby moving the upper container 3 so that the upper and lower containers are vertically aligned. Then, the upper container 3 is moved downward so that the locking tongue of the automatic lock 5 is inserted into the interior of the lower corner piece 4. During the process, the inclined surface on the right side of the locking tongue presses against the inner wall of the upper opening of the corner piece 4, causing the automatic lock 5 to move to the left. When the left surface of the locking tongue contacts the inner wall of the upper opening of the corner piece 4, the automatic lock 5 can move downward. When the inclined surface on the left side of the locking tongue contacts the inner wall of the upper opening of the corner piece 4, the automatic lock 5 moves to the right until the automatic lock 5 is fully inserted into the lower corner piece 4. At this time, the automatic lock 5 and the upper and lower corner pieces 4 are locked. When it is necessary to disassemble the automatic lock 5 and the lower corner piece 4, an external lifting device is required to apply a continuous upward and large force to the upper box 3 to separate the automatic lock 5 from the lower corner piece 4. Although the box 3 will shake during the transportation process, it is difficult to generate a continuous upward force that can lift the box 3. Therefore, it is difficult to separate the corner piece 4 from the automatic lock 5 during the transportation process, thus ensuring that the box 3 will not fall during the transportation process.

[0029] The locking structure for a cargo carrier used in transportation includes a locking mechanism 9 comprising a sliding block 92, a fixed rod 93, a rotating rod 94, and a locking block 95. The sliding blocks 92 are slidably connected to the interior of a support base 2, and the lower ends of the sliding blocks 92 are fixedly connected to the fixed rods 93. Rotating rods 94 are rotatably connected to the left and right sides of the interior of the support base 2, and each rotating rod 94 has a limit groove on its outer surface. The left and right ends of the fixed rods 93 are slidably connected to adjacent limit grooves on the same side, and the upper ends of the rotating rods 94 are fixedly connected to the locking blocks 95. The locking mechanism 9 also includes a limit rod 96, a connecting rod 97, and a pressing plate 98. The limit rod 96 is divided into... The left and right surfaces of the sliding block 92 are fixedly connected to the support base 2. Connecting rods 97 are slidably connected to both the left and right sides of the interior of the support base 2. Limiting grooves are formed on the side of the connecting rods 97 closest to the sliding block 92. The ends of the limiting rods 96 furthest from the sliding block 92 are slidably connected to the limiting grooves on the same side. Extrusion plates 98 are fixedly connected to the side of the connecting rods 97 furthest from the sliding block 92. The locking mechanism 9 also includes an adjusting bolt 91, which is threaded onto the upper side of the interior of the support base 2. The lower end of the adjusting bolt 91 is rotatably connected to the upper surface of the sliding block 92. This mechanism is used for cargo carriers and locking structures in transportation applications. When fixing body 3, place body 3 between two horizontally adjacent support bases 2, so that the insertion hole on the lower side of corner piece 4 corresponds to the vertically adjacent locking block 95, and insert the locking block 95 into the interior of the vertically adjacent corner piece 4. At this time, rotate adjusting bolt 91 to move adjusting bolt 91 upward, driving sliding block 92 to move upward, and causing fixing rod 93 to move upward. Since fixing rod 93 slides in limiting groove 1 opened on the outer surface of rotating rod 94, limiting groove 1 is a spiral groove with the central axis of fixing rod 93 as the axis, when fixing rod 93 moves upward, rotating rod 94 rotates, driving locking block 95 to rotate, and locking block 95... The lower surface of the sliding block 92 contacts the lower inner surface of the vertically adjacent corner piece 4. At the same time, the sliding block 92 moves, causing the limiting rod 96 to move upward. Since the limiting rod 96 slides inside the limiting groove 2, the connecting rod 97 slides away from the sliding block 92, causing the pressing plate 98 to slide away from the sliding block 92, so that the pressing block 98 is in close contact with the adjacent corner piece 4. When the adjusting bolt 91 can no longer rotate, the pressing block 98 is in close contact with the adjacent corner piece 4, thereby fixing the box 3 on the upper side of the support base 2. When the adjusting bolt 91 reaches the maximum moving distance, the maximum rotation angle of the corresponding locking block 95 is 135°.

[0030] The working principle of the cargo carrier and locking structure for transportation provided by this utility model is as follows: When the cargo is placed inside the container 1, the protective door 10 is closed. The protective door 10 rotates around the central axis of the hinge shaft inside the hinge, causing the rear surface of the protective door 10 to contact the front surface of the container 1. The movement of the protective door 10 moves the fixing plate 11, causing it to move into the interior of the baffle 12. At this time, the handle 8 is rotated, causing the rotating shaft 7 to rotate, which in turn causes the fixing plate 11 to rotate around the central axis of the rotating shaft 7, positioning the fixing plate 11 behind the baffle 12. The rear surface of the handle 8 then contacts the front surface of the fixing seat 13. The limiting block 14 is rotated, causing its lower end to fit tightly against the handle 8. Simultaneously, the mounting hole 15 engages with the screw inside the handle 8. With the vertical holes aligned, the bolt is inserted into the mounting hole 15, so that the lower end of the bolt is threaded into the internal threaded hole of the handle 8, thereby locking the handle 8 and thus locking the protective door 10. When using this cargo carrier and locking structure for transportation to fix the box 3, the box 3 is placed between two horizontally adjacent support seats 2, so that the insertion hole on the lower side of the corner piece 4 corresponds to the vertically adjacent locking block 95, and the locking block 95 is inserted into the interior of the vertically adjacent corner piece 4. At this time, the adjusting bolt 91 is rotated, so that the adjusting bolt 91 moves upward, driving the sliding block 92 to move upward, and the fixing rod 93 moves upward. Since the fixing rod 93 slides in the limiting groove 1 opened on the outer surface of the rotating rod 94, the limiting groove 1 is for the fixing rod 93. The spiral groove with the central axis as the axis causes the rotating rod 94 to rotate when the fixed rod 93 moves upward, which in turn rotates the locking block 95, making the lower surface of the locking block 95 contact the lower inner surface of the vertically adjacent corner piece 4. At the same time, the sliding block 92 moves, causing the limiting rod 96 to move upward. Since the limiting rod 96 slides inside the limiting groove, the connecting rod 97 slides away from the sliding block 92, causing the pressing plate 98 to slide away from the sliding block 92, making the pressing block 98 tightly attached to the adjacent corner piece 4. When the adjusting bolt 91 can no longer rotate, the pressing block 98 is tightly attached to the adjacent corner piece 4, thus fixing the box 3 on the upper side of the support base 2. When the adjusting bolt 91 reaches its maximum moving distance, it corresponds to the maximum rotation angle of the locking block 95. The angle is 135°. When it is necessary to stack the containers 3, an automatic lock 5 can be inserted into the interior of the corner piece 4 on the lower surface of the upper container 3. The automatic lock 5 consists of an upper latching block and a lower locking tongue. The automatic lock 5 adopts an automatic connector commonly used in the prior art for connecting vertically adjacent containers. After the latching block is inserted into the interior of the upper corner piece 4, the automatic lock 5 is rotated 90° so that the lower surface of the latching block contacts the lower interior surface of the upper corner piece 4. At this time, an external lifting device, such as a gantry crane, is used to connect the hook of the external lifting device to the upper container 3, thereby driving the upper container 3 to move, so that the upper and lower containers are vertically aligned. Then, the upper container 3 is moved downwards.The bolt of the automatic lock 5 is inserted into the lower corner piece 4. As the bolt is inserted downwards into the corner piece 4, the beveled surface on the right side of the bolt presses against the inner wall of the upper opening of the corner piece 4, causing the automatic lock 5 to move to the left. When the left surface of the bolt contacts the inner wall of the upper opening of the corner piece 4, the automatic lock 5 can move downwards. When the beveled surface on the left side of the bolt contacts the inner wall of the upper opening of the corner piece 4, the automatic lock 5 moves to the right until the automatic lock 5 is fully inserted into the lower corner piece 4. At this point, the automatic lock 5 and the upper... The corner fittings 4 on both sides are locked. When it is necessary to disassemble the automatic lock 5 from the lower corner fittings 4, an external lifting device is required to apply a continuous and significant upward force to the upper box 3 to separate the automatic lock 5 from the lower corner fittings 4. Although the box 3 may shake during transportation, it is difficult to generate a continuous upward force capable of lifting the box 3. Therefore, it is difficult to separate the corner fittings 4 from the automatic lock 5 during transportation, thus ensuring that the box 3 will not fall during transport.
