[0025] The following disclosure provides many different implementations or examples for different structures of the embodiments of the present invention. To simplify the disclosure of the embodiments of the present invention, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the embodiments of the present invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples of the embodiments of the present invention; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various implementations and / or arrangements discussed.
[0026] To better understand the purpose, structure, and function of this utility model, the following detailed description of a stable railway container flatcar locking structure is provided in conjunction with the accompanying drawings.
[0027] like Figures 1-5 As shown, the present invention discloses a stable railway container flatcar 9 locking structure, including a locking head 1, a fixed base 5 at the bottom of the locking head 1, and an integrally cast extension 3 on the side of the locking head 1. Due to the existence of the extension 3 and the rectangular shape of the extension 3, when the locking head 1 is rotated, the extension 3 rotates accordingly, thereby pressing against the corner piece of the container to achieve a locking effect between the flatcar 9 and the container. A fixed block 4 is installed at the bottom of the locking head 1, and a rotating block 6 is fixedly connected to the bottom of the fixed block 4. The rotating block 6 is connected to the fixed base 5 by a rotating connection. A second internal threaded hole 14 is opened at the top of the fixed base 5. A locking bolt 12 passes through the inside of the extension 3 and is threadedly connected to the second internal threaded hole 14. A through hole 13 is opened inside the extension 3, and the locking bolt 12 is inserted into the through hole 13.
[0028] By providing an extension body 3 on the side of the locking head 1, and additionally providing a locking bolt 12 between the extension body 3 and the fixed base 5, after the locking head 1 rotates to lock the corner of the container, the locking bolt 12 is used to completely lock the locking head 1 and the fixed base 5. This can prevent the locking structure from shaking or shifting during implementation, and greatly improve the stability of the locking structure during use.
[0029] A through hole 19 is opened inside the locking head 1, and a fastening screw 18 is inserted into the locking head 1. The fastening screw 18 passes through the through hole 19. A third internal threaded hole 20 is opened on the top of the fixing block 4. The fastening screw 18 is connected to the third internal threaded hole 20 by thread. A positioning hole 11 is opened on the bottom of the locking head 1. A positioning rod 10 is fixedly connected to the top of the fixing block 4. The positioning rod 10 is embedded in the positioning hole 11. Since four additional positioning rods 10 are provided between the locking head 1 and the fixing block 4, the workers have a good auxiliary positioning function when installing the locking head 1, which is more convenient to use. The positioning rods 10 are symmetrically distributed.
[0030] Since the fixed block 4 is additionally used to connect the locking head 1 and the fixed base 5, and the fastening screw 18 is used to connect and fix the locking head 1 and the fixed block 4, when the locking structure is replaced, only the top head 2 at the top of the locking head 1 is pulled out, then the two sets of fastening screws 18 are unscrewed, then the locking head 1 is clamped by a tool and pulled up, and then the locking head 1 is removed, and then a new locking head 1 is replaced, so that the maintenance and replacement work can be realized, and the entire locking structure does not need to be discarded and replaced as a whole, and the maintenance is more convenient.
[0031] The first inner threaded hole 7 is arranged in the fixed base 5, the fixed base 5 is embedded in the flat car 9, the side of the flat car 9 penetrates the locking bolt 8, the locking bolt 8 penetrates and connects the first inner threaded hole 7 through threads, and since the locking bolt 8 is additionally used to fix the flat car 9 and the fixed base 5, the installation of the fixed base 5 can have the performance of better locking.
[0032] The top of the fastening screw 18 is provided with an end, the top of the locking head 1 is provided with the top head 2, the bottom of the top head 2 is provided with the inner groove 17, the end of the fastening screw 18 is located in the inner groove 17, the bottom of the top head 2 is fixedly connected with the inlay body 15, the top of the locking head 1 is provided with the special-shaped groove 16, and the inlay body 15 is embedded in the special-shaped groove 16. Since the inner groove 17 is arranged at the bottom of the top head 2, the protruding part at the top of the fastening screw 18 can be hidden in the inner groove 17 during installation, so that the top head 2 can be well hidden during installation, and the practicability is higher.
[0033] The working principle of the stable railway container flat car 9 locking structure is as follows: when the locking structure is applied, it needs to be first installed and fixed on the railway flat car 9, and embedded in the corresponding installation groove of the flat car 9 by using the fixed base 5 structure, and then the lock bolt 8 is inserted through the side of the flat car 9 and continuously inserted through the inside of the fixed base 5, and screwed into the inside of the flat car 9, so that the installation work of the locking structure is realized, and then when the locking structure needs to fix the container, since the corner piece structure is provided at the four corners of the container, and the corner piece itself is used to connect and lock, only the hole of the container corner piece needs to be aligned with the locking head 1, and placed down so that the locking head 1 is inserted into the corner piece of the container, then a wrench or the like is inserted into the container corner piece, and the locking bolt 12 on the extension body 3 of the locking head 1 is loosened and lifted until the locking bolt 12 is lifted out of the inside of the fixed base 5, then the wrench or the like is taken out, and a stick-shaped tool such as a crowbar is used to pry the rotating locking head 1 to rotate ninety degrees, so that the extension body 3 of the locking head 1 is used to press the whole corner piece, and then the wrench or the like is used again to tighten the locking bolt 12, so that it is screwed into the other second internal thread hole 14 of the fixed base 5, so that the locking bolt 12 can completely lock the locking head 1 and the fixed base 5, so that the locking structure can be avoided from shaking or moving during implementation, thereby reducing the risk of instability and greatly improving the stability of the locking structure during use, so that the container can be fixed on the flat car 9, and finally as the use time of the locking structure increases, once the structure fails or is seriously worn and needs to be repaired or replaced, the locking head 1 and the fixed base 5 are connected by the additional fixed block 4, and the locking head 1 and the fixed block 4 are connected and fixed by the fastening screw 18, so that the locking head 1 can be replaced separately to achieve the effect of repair and replacement. During maintenance, only the top head 2 of the locking head 1 needs to be pulled out, and then the two fastening screws 18 are loosened, and then the locking head 1 is clamped by a tool and pulled up to be removed, and then a new locking head 1 is replaced and the fastening screw 18 is tightened, so that the repair and replacement work can be realized without discarding the whole locking structure for replacement, which is more convenient during maintenance.
[0034] It can be understood that the utility model is described through some embodiments, and the person skilled in the art knows that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the utility model. In addition, under the guidance of the utility model, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the application belong to the scope protected by the utility model.
