This design, by moving the adjusting bolt forward or backward and then bringing the two push blocks into contact with the front of the C-shaped seat, allows for flexible and quick adjustment of the hinge plate's front-to-back position.

Description

Technical Field

[0001] This utility model belongs to the field of container hinge technology, and in particular relates to an adjustable container side door hinge connection structure. Background Technology

[0002] An adjustable container side door hinge connection structure is a multi-functional connection component designed specifically for the container side door and the container body. It aims to solve problems such as difficulty in aligning the container side door during installation, deformation of the door body after long-term use, and hinge wear leading to jamming during opening and closing, and failure of sealing.

[0003] At this point, the staff will remove the hinges on the side door, realign the door panel with the container, drill new holes in the door, and then realign the hinges with the new holes and fix them with bolts. This method is rather clumsy because it lacks an adjustable hinge connection structure. The only way to fix the hinges to the aligned door panel is to remove the door panel and drill new holes. This is not only inefficient, but also increases the workload of the staff. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable container side door hinge connection structure. By setting a front-to-back adjustment mechanism, specifically by turning the adjusting nut counterclockwise with a wrench, the C-shaped seat moves forward to the desired position and stops. Then, turning the upper bolt clockwise causes it to rotate downwards and press the push block downwards. The push block pushes the support block backwards via an inclined surface until the back of the support block is in close contact with the front of the C-shaped seat. Then, turning the lower bolt counterclockwise causes the lower support block to contact the C-shaped seat. This design, by moving the adjusting bolt forward or backwards and then bringing the two push blocks into contact with the front of the C-shaped seat, allows for flexible adjustment of the hinge plate's front-to-back position. This is convenient and quick, solving the problem of existing methods that require aligning the door panel with the container, drilling new holes, and then fixing the hinge to the new holes to realign the side door with the container, which is cumbersome, time-consuming, and labor-intensive.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an adjustable container side door hinge connection structure, including a mounting base. Two horizontal plates are symmetrically mounted on the front of the mounting base. A fixing block is fixedly connected to the side of each horizontal plate that is close to it. A C-shaped seat is provided inside each horizontal plate, and a hinge plate is hinged inside the C-shaped seat. Vertical blocks are fixedly connected to the top and bottom of the C-shaped seat, and horizontal blocks are fixedly connected to the side of each vertical block that is far from it. The structure also includes: a front-to-back adjustment mechanism, located inside the fixing block and on the left side of the C-shaped seat, for moving the hinge plate forward or backward; the front-to-back adjustment mechanism includes a support block and a push block; bolts are installed inside the fixing block, and adjusting bolts are provided on the back of the C-shaped seat; and a vertical adjustment mechanism, located on the outer surface of the vertical blocks, for adjusting the hinge plate upward or downward. Both the support block and the push block have inclined surfaces that are compatible with each other.

[0007] Furthermore, the front and rear adjustment mechanism includes a horizontal groove inside the fixed block, the support block slidingly limiting the horizontal groove, a vertical groove inside the fixed block, the push block slidingly limiting the vertical groove, and threaded grooves on the opposite sides of the two fixed blocks, with the bolt threaded into the threaded grooves. A movable groove is inside the horizontal plate, and the vertical block slidingly limiting the movable groove. The horizontal groove, vertical groove, and threaded grooves are interconnected, and the horizontal and vertical grooves are arranged in a cross shape. When the C-shaped seat moves to its limit position, the support block remains inside the support block and will not disengage from the horizontal groove.

[0008] Furthermore, the up-down adjustment mechanism includes several shims, and two receiving grooves are formed on the side of the shims near the hinge plate; the shims are C-shaped and are adapted to the outer surface of the vertical block.

[0009] Furthermore, an adjusting nut is fixedly connected to the outer surface of the adjusting bolt, and a round block is fixedly connected to the front side of the adjusting bolt; a thread is provided on the back side of the outer surface of the adjusting bolt, and the adjusting nut is located at the center of the outer surface of the adjusting bolt.

[0010] Furthermore, the C-shaped seat has an outer vertical groove on its back and an inner vertical groove inside. The adjusting bolt is slidably limited to the outer vertical groove, and the round block is slidably limited to the inner vertical groove. The outer and inner vertical grooves are interconnected. Since the adjusting bolt cannot move up and down, the round block will slide in the inner vertical groove when the C-shaped seat moves up and down, allowing the C-shaped seat to move smoothly without being stuck by the adjusting bolt.

[0011] Furthermore, the mounting base has a second threaded groove on its front side, and the adjusting bolt is threadedly connected to the second threaded groove.

[0012] Furthermore, two spring pieces are fixedly connected to the side of the gasket away from the hinge plate, and two grooves are opened on the side of the two horizontal blocks that are close to each other; the receiving groove and the groove are used to receive the spring pieces, and the spring pieces are elastically set so that when the spring pieces are squeezed, they will deform and enter the grooves.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model features a front-to-back adjustment mechanism. Specifically, turning the adjusting nut counterclockwise with a wrench moves the C-shaped seat forward until it reaches the desired position. Then, turning the upper bolt clockwise moves the bolt downward and presses the push block downward. The push block pushes the support block backward through the inclined plane until the back of the support block is in close contact with the front of the C-shaped seat. Finally, turning the lower bolt counterclockwise makes the lower support block contact the C-shaped seat. This design allows for flexible adjustment of the hinge plate's front-to-back position by moving the adjusting bolt forward or backward, and then having the two push blocks contact the front of the C-shaped seat. This is convenient and quick.

[0015] 2. This utility model features an up-and-down adjustment mechanism. Specifically, the two support blocks are first detached from the C-shaped base. Then, the door panel is gently pried up using a tool. Subsequently, shims are inserted alternately on the upper vertical block, causing the spring clips of the lower shims to embed into the receiving grooves of the upper shims. Finally, the spring clips of the inserted shims will embed into the upper grooves. When the last shim is inserted at the bottom, the already installed shims will squeeze the spring clips of the new shims, causing them to deform and enter the receiving grooves of the already installed shims. Thus, the shims stacked on the top and bottom are connected as a whole through their own receiving grooves and spring clips. This design allows for quick and flexible adjustment of the hinge plate height by increasing or decreasing the number of shims on the outer sides of the upper and lower vertical blocks.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The front-to-back adjustment mechanism 2 includes a horizontal groove 21 inside the fixed block 12, a support block 211 that slides and limits the movement of the horizontal groove 21, a vertical groove 22 inside the fixed block 12, a push block 221 that slides and limits the movement of the vertical groove 22, and threaded grooves 23 on the opposite sides of the two fixed blocks 12, with bolts 231 threadedly connected to the threaded grooves 23. A moving groove 24 inside the horizontal plate 11, with the vertical block 15 that slides and limits the movement of the moving groove 24. The horizontal groove 21, vertical groove 22, and threaded groove 23 are interconnected, and the horizontal groove 21 and vertical groove 22 are arranged in a cross shape. The up-and-down adjustment mechanism 3 includes several shims 31, with two receiving grooves 311 on the side of the shim 31 closest to the hinge plate 14. The shims 31 are C-shaped and fit the outer surface of the vertical block 15. An adjusting nut 251 is fixedly connected to the outer surface of the adjusting bolt 25, and a round block 252 is fixedly connected to the front of the adjusting bolt 25. A thread is provided on the back of the outer surface of the adjusting bolt 25, and the adjusting nut 251 is located at the center of the outer surface of the adjusting bolt 25.

[0028] Two spring clips 312 are fixedly connected to the side of the washer 31 away from the hinge plate 14. Two grooves 32 are opened on the side of the two horizontal blocks 16 that are close to each other. First, let the two support blocks 211 detach from the C-shaped seat 13. Then, use a tool to gently pry the door panel up. Then, insert the washer 31 into the upper vertical block 15 alternately, so that the spring clips 312 of the lower washer 31 are embedded in the receiving grooves 311 of the upper washer 31. Finally, the spring clips 312 inserted into the washer 31 will be embedded in the upper grooves 32. The last washer 31 at the bottom When inserted, the installed pad 31 will squeeze the spring piece 312 of the new pad 31, causing it to deform and enter the receiving groove 311 of the installed pad 31. At this point, the pads 31 stacked on top and bottom are connected as a whole through their own receiving grooves 311 and spring pieces 312. This setting adjusts the height of the hinge plate 14 by increasing or decreasing the number of pads 31 on the outside of the upper and lower vertical blocks 15, which is quick and flexible. The receiving grooves 311 and the recesses 32 are both used to receive the spring pieces 312, which are elastically set.

[0029] A specific application of this embodiment is as follows: In use, the mounting base 1 is installed at the side door of the container, and the hinge plate 14 is installed on the side door of the container. When adjusting, the adjusting nut 251 is turned counterclockwise with a wrench. Since the adjusting bolt 25 is threadedly connected to the threaded groove 26, the adjusting bolt 25 will move forward along with the C-shaped seat 13. When the C-shaped seat 13 moves to the desired position, the adjusting nut 251 is stopped. Then, the upper bolt 231 is turned clockwise. The bolt 231 rotates and moves down, which will press the push block 221 down. The push block 221 will also press and push the support block 21 through its own inclined surface. 1. Move to the back. When the back of the support block 211 is in close contact with the front of the C-shaped seat 13, stop rotating the bolt 231. Then, rotate the lower bolt 231 counterclockwise so that the lower support block 211 contacts the C-shaped seat 13. During the movement of the C-shaped seat 13, it slides and limits the movement of the top and bottom vertical blocks 15 with the two moving slots 24 respectively, so that the C-shaped seat 13 moves in a straight line. At this time, the position of the C-shaped seat 13 has been adjusted. The hinge plate 14 and the side door are adjusted together. At the same time, the hinge plate 14 and the side door can be moved to the front or back by rotating the adjusting nut 251 and the two bolts 231.

[0030] When adjusting the hinge plate 14 upwards or downwards, first ensure the two support blocks 211 are no longer in contact with the C-shaped seat 13. Then, use a jack or pry bar to gently pry the door panel upwards. At this point, the C-shaped seat 13 will move upwards. After adjusting the distance, insert shims 31 alternately on the left or right side of the upper vertical block 15 as needed. First, insert the first shim 31 into the left side of the vertical block 15, ensuring the bottom of the shim 31 contacts the top of the upper fixing block 12. Then, insert the second shim 31 into the right side of the vertical block 15, ensuring the bottom of the second shim 31 contacts the top of the first shim 31. Simultaneously, ensure the two spring clips 312 at the top of the first shim 31 embed into the two receiving grooves 311 at the bottom of the second shim 31. Then, release the jack and pry bar. The C-shaped seat 13 will move downwards, at which point the second shim 31... The two spring clips 312 at the top will be embedded in the two grooves 32 at the bottom of the upper horizontal block 16. At this time, the two pads 31 cannot move to the left or right. The two pads 31 at the bottom are operated in the same way. When inserting the last pad 31, since the gap between the installed pad 31 and the fixing block 12 can only accommodate the insertion of the last pad 31, the pads 31 are inserted. When the spring clip 312 contacts the pad 31, it will squeeze the spring clip 312, causing it to deform and enter the receiving groove 311 of the installed pad 31. At this time, the gaps between the two horizontal blocks 16 on the side close to each other and the two fixing blocks 12 on the side far away from each other are both equipped with pads 31. Therefore, the C-shaped seat 13 cannot move up or down. At this time, the height of the hinge plate 14 has been adjusted. The operation to move the hinge plate 14 down is the same as above.
