Description

Technical Field

[0001] This utility model relates to the field of number spraying technology, specifically a high-speed train number spraying model. Background Technology

[0002] A D-Series High-Speed ​​Train, also known as a "high-speed train," is a relatively new transportation term in mainland China. It refers to a type of modern train consisting of powered cars (motor cars) and unpowered cars (trailer cars), operating in a fixed formation throughout its normal service life. Currently, most existing painting equipment has complex connections between the number plates and the device. When workers change different number plates for painting, they typically need to remove each bolt individually, significantly slowing down the installation and removal speed of the number plates.

[0003] Patent application CN221678342U discloses a special vehicle for spraying vehicle markings on train carriages, comprising: a marking track located beside the railway tracks, on which a marking machine for spraying markings on the carriage surfaces is movably mounted, and the total length of the marking track is not less than the length of one carriage. When the train is stopped on the tracks, the marking machine is driven along the marking track to a designated location to begin spraying markings on the carriage surfaces. After spraying the first carriage, the machine continues to move along the marking track to spray markings on the surface of the next carriage. Since each carriage is of standard size, the marking machine can begin the automated marking process simply by stopping the train in position. Because the marking track covers at least one carriage, the entire carriage surface can be fully covered in one go by moving the marking machine along the track, greatly improving marking efficiency.

[0004] However, the spraying efficiency of the above-disclosed marking devices is generally low, their structure is huge and complex, making them unsuitable for teaching purposes. Furthermore, they have low flexibility and cannot quickly adjust the spraying position according to actual needs during use. Utility Model Content

[0005] The purpose of this invention is to provide a high-speed train number spraying model to address the problems of existing number spraying devices, such as low spraying efficiency, large and complex structure, unsuitability for teaching, low degree of freedom, and inability to quickly adjust the spraying position according to actual needs.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a high-speed train number spray painting model, comprising an outer frame, with threaded seats provided at each of the four diagonal corners of the outer frame, and screws threadedly mounted on the threaded seats, with suction cups movably mounted at the bottom of the screws; symmetrical inner rails are fixedly provided in the middle of the outer frame, and inner grooves are formed on the inner walls of the inner rails, with a moving frame slidably mounted between the inner grooves, the thickness of the moving frame being much smaller than the height of the inner grooves; mounting grooves are formed on the inner walls of the moving frame, with multiple sets of license plates slidably mounted between the mounting grooves, and multiple sets of positioning bolts threadedly mounted on the moving frame to limit the upper and lower ends of the moving frame.

[0007] As a further improvement of this utility model, a rotating arm is provided at the top of the screw.

[0008] As a further improvement of this utility model: a limiting protrusion is provided at the bottom of the screw, and a limiting groove that cooperates with it is provided inside the suction cup.

[0009] As a further improvement of this utility model, a handle is also fixedly installed on the top of the exercise frame.

[0010] As a further improvement of this utility model: the license plate has a concave structure, and a rubber pad is also provided on the bottom outer wall of the license plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention utilizes multiple suction cups for quick positioning and installation on the outer frame. The position of each suction cup can be independently adjusted using screws, ensuring stable positioning even on uneven vehicle bodies. In use, different license plates are first installed onto the moving frame. Then, the frame is moved to the appropriate position using the handle. Finally, the frame is secured using multiple positioning bolts. At this point, the bottom of the license plate is firmly attached to the vehicle body. This design improves the stability and flexibility of the train number painting model. Attached Figure Description

[0019] The following will be combined with the appendix Figures 1 to 3 The technical solution of this utility model has been clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] This utility model provides an improved version of a high-speed train car number spray painting model, such as... Figures 1-3 As shown, the device includes an outer frame 1, with threaded seats 2 at each of the four corners of the outer frame 1. Threaded rods 3 are threaded onto the threaded seats 2, and suction cups 4 are movably mounted at the bottom of the threaded rods 3. Symmetrical inner rails 8 are fixedly mounted in the middle of the outer frame 1. Inner grooves 9 are formed on the inner walls of the inner rails 8, and a moving frame 10 is slidably mounted between the inner grooves 9. The thickness of the moving frame 10 is much smaller than the height of the inner grooves 9. Mounting grooves 12 are formed on the inner walls of the moving frame 10, and multiple sets of number plates 13 are slidably mounted between the mounting grooves 12. Multiple sets of positioning bolts 14 are threaded onto the moving frame 10 to limit the upper and lower ends of the moving frame 10.

[0021] This invention utilizes multiple suction cups 4 for quick positioning and installation of the outer frame 1. The position of each suction cup 4 can be independently adjusted using screws 3, ensuring stable positioning even on uneven vehicle bodies. In use, different license plates 13 are first installed onto the moving frame 10. Then, the moving frame 10 is moved to the appropriate position using handles 11. Finally, multiple positioning bolts 14 are used to position the moving frame 10, ensuring the bottom of the license plate 13 is flush against the vehicle body. This design improves the stability and flexibility of the train number painting model.

[0022] See appendix Figure 1 -Appendix Figure 2 The top of the screw 3 is provided with a rotating arm 5.

[0023] In this embodiment: a rotating arm 5 structure is designed to facilitate the rotation of the screw 3.

[0024] See appendix Figure 2 The bottom of the screw 3 is provided with a limiting protrusion 6, and the inside of the suction cup 4 is provided with a limiting groove 7 that matches it.

[0025] In this embodiment: when the screw 3 rotates, in order to ensure that it can rotate freely relative to the suction cup 4 and thus better grip the vehicle body, a mutually cooperating limiting protrusion ring 6 and limiting groove 7 structure is designed.

[0026] See appendix Figure 1 and attached Figure 3 A handle 11 is also fixedly installed on the top of the exercise frame 10.

[0027] In this embodiment: a handle 11 structure is designed to facilitate moving the motion frame 10 to the desired position.

[0028] See appendix Figure 3 License plate number 13 has a concave structure, and a rubber pad is also installed on the bottom outer wall of license plate number 13.

[0029] In this embodiment: In order to improve the fit and prevent the license plate 13 from scratching the vehicle body, a soft rubber pad is provided at its bottom.

[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and inventive features disclosed herein.
