Description

Technical Field

[0001] The utility model relates to the technical field of container corner fittings, in particular to a top clamping structure of a container corner fitting. Background Technique

[0002] A container is a component tool that can load packaged or unpackaged goods for transportation and is convenient for loading and unloading with mechanical equipment. The greatest success of the container lies in the standardization of its products and the resulting complete set of transportation systems, which can standardize a huge object weighing dozens of tons and gradually establish a logistics system that matches ships, ports, shipping lines, roads, transfer stations, bridges, tunnels, and multimodal transport globally. The role of container corner fittings in the complex transportation system cannot be ignored. In the operations of lifting, handling, fixing, and stacking containers, container corner fittings play a key role.

[0003] During the installation process of container corner fittings, it is necessary to clamp and lift the corner fittings. However, currently, when clamping and lifting container corner fittings, the clamping structure only clamps two opposite faces of the container corner fittings, and there is a problem of easy detachment due to gravity during use. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a top clamping structure of a container corner fitting.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A top clamping structure of a container corner fitting includes a central block. Telescopic mechanisms are fixed at both the left and right ends of the central block, and a first clamping block is fixed at the output end of the telescopic mechanism. Second clamping blocks are arranged at both the front and rear ends of the central block, and the second clamping blocks are slidably connected to the central block through a driving mechanism. The connection line between the two first clamping blocks is perpendicular to the connection line between the two second clamping blocks. Both the first clamping block and the second clamping block are arranged in a "U" - shaped structure. It also includes a corner fitting body. A through - hole is opened on the top surface of the corner fitting body. The first clamping block is inserted into the through - hole through the telescopic mechanism and pre - positions the central block and the second clamping block. The second clamping block is inserted into the through - hole through the driving mechanism to complete clamping and limiting.

[0007] Preferably, the first clamping block and the second clamping block are in side - surface contact with the side of the through - hole on the top surface of the corner fitting body.

[0008] Preferably, the inner side surfaces of the first clamping block and the second clamping block facing the open end are both flat surfaces.

[0009] Preferably, the inner side surfaces of the first clamping block and the second clamping block facing the open end are both arc surfaces, and the radian of the arc surface is equal to the radian of the through - hole on the top surface of the corner fitting body.

[0010] Preferably, the side surface of the first clamp facing the opening end is set as a plane, and the side surface of the second clamp facing the opening end is set as an arc surface, and the curvature of the arc surface is equal to the curvature of the through hole on the top surface of the corner piece body.

[0011] Preferably, the ratio of the length to the width of the central block is equal to the ratio of the length to the width of the through hole on the top surface of the corner piece body.

[0012] Preferably, a handle is fixed on the top surface of the center block.

[0013] Preferably, the telescopic mechanism includes a fixed cylinder, which is fixed to the end of the center block, a telescopic rod is slidably arranged in the fixed cylinder, the end of the telescopic rod is fixedly connected to the clamping block 1, and a pressure spring wrapped around the telescopic rod is arranged between the clamping block 1 and the fixed cylinder.

[0014] Preferably, the driving mechanism includes a driving motor, which is arranged in the middle of the center block. The driving motor is a bidirectional motor, and both output ends of the driving motor are provided with threaded rods. The two threaded rods are arranged in a mirror image, and threaded blocks are threadedly arranged on the threaded rods. The threaded blocks are provided with connecting rods that penetrate the center block and are slidably connected to the center block, and the connecting rods are fixedly connected to the second clamping block.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model first drives the clamping block one and the clamping block two to pre-position through the telescopic mechanism, and then drives the clamping block two to clamp and limit through the driving mechanism. At the same time, the clamping block with the U-shaped structure is plugged into the through hole of the angle piece body, thereby preventing the angle piece body from falling off and improving the stability of clamping and limiting.

[0017] 2. The utility model changes the shape of the side surface of the clamping block facing the opening end and selects a suitable combination according to through holes of different shapes, thereby making the product applicable to more situations and increasing the scope of application.

[0024] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0025] like Figure 1 As shown, as a container corner fitting top surface clamping structure of the utility model, it includes a corner fitting body 6 and a center block 1. The top surface of the corner fitting body 6 is provided with a through hole, such as Figure 3 As shown, fixed cylinders 21 are symmetrically fixed at the left and right ends of the center block 1, a telescopic rod 22 is slidably arranged in the fixed cylinder 21, a clamping block 3 is fixed at the end of the telescopic rod 22, and a pressure spring 23 wrapped around the telescopic rod 22 is arranged between the clamping block 3 and the fixed cylinder 21. The pressure spring 23 ensures that the two clamping blocks 3 always contact the side of the through hole, and at the same time, the center block 1 is ensured to be located at the center of the through hole through the force applied at both ends, so that the pre-positioning of the center block 1 is achieved through the telescopic mechanism 2 composed of the fixed cylinder 21, the telescopic rod 22 and the pressure spring 23, which lays a good foundation for the subsequent clamping and limiting.

[0026] A driving motor 51 is arranged in the middle of the central block 1. Figure 4 As shown, the driving motor 51 is a bidirectional motor, and both output ends of the driving motor 51 are provided with threaded rods 52, the two threaded rods 52 are mirror-imaged, and threaded blocks 53 are threadedly provided on the threaded rods 52, and the threaded blocks 53 are provided with connecting rods 54 that penetrate the center block 1 and are slidably connected to the center block 1, and a clamping block 2 4 is fixed at the end of the connecting rod 54. The driving motor 51 drives the two threaded rods 52 to rotate, thereby driving the two threaded blocks 53 to move in the opposite direction, so that the reverse movement of the two clamping blocks 2 4 is realized through the driving mechanism 5 composed of the driving motor 51, the threaded rods 52, the threaded blocks 53 and the connecting rods 54, and then the diagonal piece body 6 of the clamping block 2 4 is clamped and limited.

[0027] like Figure 2As shown, both the first clamping block 3 and the second clamping block 4 are set in a "U" - shaped structure, and the connection line between the two first clamping blocks 3 is perpendicular to the connection line between the two second clamping blocks 4. The clamping blocks with a "U" - shaped structure are inserted into the through - holes, avoiding the dropping of the angle - shaped part body 6 due to gravity when lifting the angle - shaped part body 6, thus improving the stability. The perpendicular first clamping block 3 and second clamping block 4 ensure that the clamping blocks are evenly stressed when clamping the angle - shaped part body 6, which is beneficial to the stability of the angle - shaped part body 6.

[0028] When the through - hole is square, the inner sides of the first clamping block 3 and the second clamping block 4 facing the open end are both set as flat surfaces. When the through - hole is circular, the inner sides of the first clamping block 3 and the second clamping block 4 facing the open end are both set as arc surfaces, and the radian of the arc surface is equal to the radian of the through - hole on the top surface of the angle - shaped part body 6. When the through - hole is oval, the inner side of the first clamping block 3 facing the open end is set as a flat surface, and for the part of the first clamping block 3 in contact with the straight line of the through - hole, the inner side of the second clamping block 4 facing the open end is set as an arc surface, and the radian of the arc surface is equal to the radian of the through - hole on the top surface of the angle - shaped part body 6. Selecting appropriate first clamping block 3 and second clamping block 4 according to the shape of the through - hole ensures that the first clamping block 3 and the second clamping block 4 are in surface contact with the through - hole. By surface contact, the contact area between the first clamping block 3 and the second clamping block 4 and the through - hole is increased, thereby increasing the friction force and further increasing the stability. At the same time, by changing the shape of the inner side of the clamping block facing the open end and selecting appropriate combinations according to different - shaped through - holes, the product is applicable to more situations, increasing the scope of application.

[0029] The ratio of the length to the width of the central block 1 is equal to the ratio of the length to the width of the through - hole on the top surface of the angle - shaped part body 6. By the equal ratio, the stability of the force on the central block 1 is ensured when lifting the angle - shaped part body 6 through the central block 1, which is beneficial to improving the stability of the angle - shaped part body 6. A handle 7 is fixed on the top surface of the central block 1, which is beneficial to the lifting of the angle - shaped part body 6 through the handle 7.

[0030] During use, by pressing the first clamping block 3, the compression spring 23 contracts, and then the central block 1 is placed in the through - hole. When releasing the first clamping block 3, the compression spring 23 rebounds, so that the first clamping block 3 is inserted into the side of the through - hole, and at the same time, the central block 1 is located at the center of the through - hole. Through the driving mechanism 5, the two second clamping blocks 4 move in opposite directions until the second clamping blocks 4 are inserted into the side of the through - hole, thus completing the clamping and limiting work. Finally, the angle - shaped part body 6 is lifted through the handle 7.

[0031] The technical scope of the present utility model is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above - mentioned embodiments without departing from the technical idea of the present utility model, and these deformations and modifications should all fall within the protection scope of the present utility model.
