[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example:

[0017] The adjustable log bridge provided by this utility model is specially designed for military training, and its structural design and functional characteristics are highly compatible with the diverse training needs of the troops.

[0018] As the core load-bearing component of the entire log bridge, the bridge deck 11 has symmetrical first mounting slots at both ends. Through these first mounting slots, adjustable support components for supporting the bridge deck 11 can be positioned and installed. This allows the device to adjust the bridge height according to the terrain differences of different training grounds, improving the device's adaptability to various complex terrain environments and meeting the needs of diverse training scenarios. The adjustable support component consists of a sliding mounting frame 12 and a mounting base 13. A sliding bracket 14 is mounted on the top of the mounting base 13, and the sliding mounting frame 12 and the sliding bracket 14 are slidably connected. With this sliding connection, the position of the sliding mounting frame 12 on the sliding bracket 14 can be easily changed, realizing the adjustment of the height of the bridge deck 11. This improves the device's height adjustment capabilities and enhances its versatility in different training scenarios.

[0019] The height adjustment component consists of a servo motor 19 and an adjustment rod 21. The adjustment rod 21 is threadedly connected to the sliding mounting bracket 12. A motor bracket is provided on the top of the mounting base 13, and the servo motor 19 is mounted on the motor bracket. One end of the adjustment rod 21 is connected to the output shaft of the servo motor 19. In actual operation, simply starting the servo motor 19 will drive the adjustment rod 21 to rotate. Utilizing the threaded connection principle, the lifting and lowering of the sliding mounting bracket 12 is controlled, allowing the device to reach the required height. This improves the convenience of height adjustment and provides convenience for military training operations.

[0020] A button box is specially installed on one side of one of the sliding mounting brackets 12; this facilitates the operation of the servo motor 19 by the troops, making the operation process of the device simple and clear, improving the ease of operation of the device, helping soldiers to quickly master the adjustment operation, and improving training efficiency.

[0021] like Figure 2 , Figure 4 As shown, the guardrail mounting frame 15 is equipped with a retractable guardrail. The retractable guardrail consists of a horizontal bar 22 and two sets of uprights 23. Two sets of rotating rods 24 are symmetrically inserted through the guardrail mounting frame 15, and the two sets of uprights 23 are respectively fitted onto the rotating rods 24. By rotating the rods 24, the angle of the uprights 23 can be adjusted, so that the guardrail can be unfolded when training is needed to provide reliable protection for soldiers. When training is over and not in use, the guardrail can be stored away to save space. This improves the device's ability to utilize space and provide protection, enhances the device's adaptability to different usage states, and ensures safe training.

[0022] The top and one side of each column 23 have a third slot, in which a magnetic block 25 is installed. Two sets of protrusions are symmetrically arranged at the bottom of the crossbar 22, and these protrusions respectively engage with the third slots at the top of the two columns 23. The cooperation between the magnetic block 25 and the slots ensures the reliability of the guardrail during use, improves its stability, and provides strong protection for soldier training safety. The magnetic block 25 can be made of ferrite magnet.

[0023] Each of the crossbar 22 and the two sets of uprights 23 has a fourth mounting slot, in which a luminous panel 26 is installed. Considering that troops may conduct training at night or in low-light conditions, the luminous panel 26 provides guidance for soldiers in dimly lit environments, ensuring safe training under various lighting conditions and improving the device's safety in different lighting environments. A handle is installed on one side of each upright 23 for easy gripping by soldiers, providing additional safety, especially during more challenging training maneuvers, thus enhancing the device's user-friendliness for soldiers. The luminous panel 26 is a photoluminescent type.

[0024] like Figures 1 to 3 As shown, the anti-slip rubber pad 16 installed on the top of the bridge deck 11 is essential; the anti-slip rubber pad 16 increases friction, prevents soldiers from slipping during training marches, improves the safety of the device during use, and reduces the risk of training accidents.

[0025] Two sets of second mounting slots are symmetrically opened between the two sets of first mounting slots, and first reinforcing ribs 17 are installed in them. The setting of the first reinforcing ribs 17 enhances the structural strength of the bridge deck 11, ensuring that the device remains stable and reliable when bearing the weight of soldiers, and improving the load-bearing capacity of the device. Four sets of first slots are symmetrically opened on the first reinforcing ribs 17. Third mounting slots are opened at the top and bottom of the bridge deck 11 adjacent to the four sets of first slots. A clamping plate 18 is installed in the third mounting slot. The clamping plate 18 is also connected to the two sets of first slots symmetrically opened between the two sets of first reinforcing ribs 17. The two sets of clamping plates 18 are connected by bolts. Through this rigorous connection method, the connection between the first reinforcing ribs 17 and the bridge deck 11 is further strengthened, and the reliability of the device is improved during long-term high-intensity training.

[0026] Two sets of second slots are symmetrically provided on the sliding mounting frame 12, and both ends of the first reinforcing rib 17 are locked in the adjacent second slots; this ensures that the structure of the device remains stable during the height adjustment process, improves the stability of the device during height adjustment, and ensures that the training process is not affected.

[0027] A footboard 27 is installed on one side of the sliding mounting bracket 12 to assist soldiers in getting on and off the bridge after height adjustment. The footboard 27 facilitates soldiers' smooth entry and exit from the bridge after the height of the bridge panel 11 is adjusted, improving the convenience of the device during use. Three sets of second reinforcing ribs 28 are installed at the bottom of the two sets of guardrail mounting brackets 15, further enhancing the stability of the guardrail mounting brackets 15 and making the protective structure of the device more robust and reliable. Anti-slip grooves are opened on the top of the anti-slip rubber pad 16 and the top of the footboard 27. The anti-slip grooves further increase the friction, making the device perform better in terms of anti-slip performance, comprehensively improving the safety of the device in terms of anti-slip, and providing a solid guarantee for troop training.

[0028] The specific usage and function of this embodiment are as follows: When the height of the log bridge needs to be adjusted during troop training, the operator moves to the vicinity of the sliding mounting bracket 12 equipped with the button box; then, presses the corresponding button on the button box to start the servo motor 19; at this time, the output shaft of the servo motor 19 drives the adjusting rod 21 to start rotating; since the adjusting rod 21 and the sliding mounting bracket 12 are connected by a thread, during the rotation of the adjusting rod 21, the sliding mounting bracket 12 will move up and down along the sliding support 14, thereby raising or lowering the bridge panel 11 to a suitable height that meets the training requirements; after reaching the desired height, the button is released, the servo motor 19 stops running, and the height adjustment operation is thus successfully completed.

[0029] When using the guardrail during military training, soldiers need to rotate the upright post 23 around the rotating rod 24 until the upright post 23 is perpendicular to the bridge deck 11. At this time, align the protrusion at the bottom of the crossbar 22 with the magnetic block 25 in the third slot at the top of the upright post 23, and then gently lower the crossbar 22. The magnetic block 25 will then magnetically attract the protrusion of the crossbar 22, thus successfully completing the installation of the guardrail. When the training is over and the guardrail is no longer needed, the reverse operation procedure is performed. First, carefully remove the crossbar 22, then rotate the upright post 23 and store it in the third slot on one side of the guardrail mounting bracket 15, ensuring that the guardrail is neatly stored and does not affect subsequent operations or site layout.

[0030] During military training, when soldiers walk on the bridge deck 11, they directly contact the anti-slip rubber pad 16 located on top of the bridge deck 11. The special material used in the anti-slip rubber pad 16 itself has a certain degree of friction, which can provide basic anti-slip protection for soldiers. At the same time, the anti-slip grooves carefully opened on its top further increase the friction between the sole of the shoe and the rubber pad, reducing the risk of soldiers slipping during walking. Similarly, the anti-slip grooves opened on the top of the step 27 play the same role. When soldiers go up and down the bridge via the step 27, the anti-slip grooves can ensure that they have a good anti-slip effect, ensuring the safety and smoothness of going up and down the bridge.

[0031] When night falls or the troops are in a dimly lit training environment, the luminous panels 26 installed on the crossbars 22 and uprights 23 will emit light naturally. These photoluminescent panels 26 can continuously emit soft light under low light conditions, allowing soldiers to see the outline and specific location of the log bridge from a distance, thereby guiding them safely to the log bridge and successfully completing the training walk on the bridge, providing reliable safety guidance for training at night or in low light conditions.

[0032] The first reinforcing rib 17 under the bridge deck 11 is initially connected by locking its two ends into the second slot of the sliding mounting bracket 12; at the same time, the first slot of the first reinforcing rib 17 is connected to the mounting plate 18, and the adjacent mounting plates 18 are fixed with bolts; this rigorous connection method enhances the structural strength and stability of the bridge deck 11, ensuring that the log bridge maintains reliable performance during the various loads and impacts of soldiers' training, and provides solid hardware support for troop training.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
