As a key facility to ensure the safe stopping of trains, prevent false signals, and avoid accidents such as rear-end collisions, the performance of automatic train entry protection equipment is directly related to the safety of passengers and the stable operation of the rail transit system. Therefore, regular, efficient and accurate inspection and maintenance of automatic train entry protection equipment has become a necessary measure to ensure the safe operation of trains.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing multi-functional toolboxes for the maintenance of automatic protection equipment at train stations are not convenient for securing and cushioning the precision equipment used for maintenance. This can lead to damage to the precision equipment during transportation due to shaking and collisions, affecting the service life and reliability of the maintenance equipment. Moreover, the hard box usually contacts the ground directly, which is not conducive to the use of cushioning and shock absorption structures. As a result, the box is prone to tilting or violent shaking when transported on uneven roads, affecting the stability and safety of the equipment inside the box.

[0004] To address this, a multi-functional toolbox for the maintenance of automatic protection equipment for trains entering stations is proposed. Utility Model Content

As a result, the precision equipment is damaged due to shaking and collision during transportation, affecting the service life and reliability of the maintenance equipment. Moreover, the hard box body usually directly contacts the ground, which is not convenient for the cushioning and shock absorption structure. Therefore, when transporting on uneven roads, the box body is prone to tilting or violent shaking, affecting the stability and safety of the equipment inside the box.

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

[0016] 1. This application provides multi-dimensional vibration protection for precision maintenance equipment through a maintenance protection component. Compared with traditional toolboxes that rely solely on cavities to store tools and lack targeted shock absorption measures, this component effectively solves the problem of damage to precision equipment caused by shaking and collision during transportation, improves the integrity and reliability of maintenance equipment, and can achieve precise fixation and multi-directional shock absorption protection for high-precision instruments such as sensors and control units.

[0017] 2. This application uses a buffer component to cushion the toolbox when it is subjected to ground impact or placed on uneven surfaces, preventing the box from tilting or shaking violently. Compared with the traditional toolbox design where the hard box body directly contacts the ground and lacks shock absorption structure, this component solves the problem of internal equipment impact damage caused by ground bumps when transporting the toolbox in complex environments such as beside tracks and in tunnels. It improves the applicability of the toolbox in harsh working environments and can achieve all-round impact cushioning function for the equipment inside the box, ensuring the stability of the maintenance tools during transportation.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A multi-functional toolbox for the maintenance of automatic protection equipment for trains entering stations includes a toolbox body 1, a top cover 2 slidably connected to the top of the toolbox body 1, a maintenance and protection component 4 inside the toolbox body 1, and a buffer component 5 at the bottom of the toolbox body 1.

[0028] The maintenance and protection assembly 4 includes a support frame 401 fixedly connected inside the toolbox body 1. A connecting spring 402 is fixedly connected to the bottom of the support frame 401. A damping rod 403 is provided inside the connecting spring 402. A support seat 404 is fixedly connected to the top of the damping rod 403. Limiting rods 405 are fixedly connected to both sides of the support seat 404. Compression springs 406 are sleeved on both sides of the limiting rods 405. A protective clamp 407 is fixedly connected to the inner side of the compression springs 406. A rubber pad 408 is adhered to the inner side of the protective clamp 407. An adjusting seat 409 is fixedly connected to the inner side of the protective clamp 407. The adjusting seat 409 is slidably connected to the limiting rod 405.

[0029] In this embodiment: By manually pushing the adjusting seat 409 outward, the adjusting seat 409 slides along the limiting support rod 405, causing the protective clamps 407 on both sides to move synchronously. At this time, the compression spring 406 sleeved on the limiting support rod 405 is compressed, storing elastic potential energy, causing the distance between the protective clamps 407 to increase to a size greater than the equipment size. After the equipment is stably placed on top of the support seat 404, the adjusting seat 409 is released. Due to elastic reset, the compression spring 406 pushes the protective clamps 407 to move inward until the rubber pad 408 on the inner side of the protective clamp 407 is tightly fitted with the side of the equipment. The rubber pad 408 buffers the lateral impact on the equipment through elastic deformation, while preventing... The protective clamp 407 is precisely limited by the sliding trajectory of the adjusting seat 409 on the limiting support rod 405 to avoid displacement. When the equipment is subjected to vibration, the connecting spring 402 and the internal damping rod 403 at the bottom of the support seat 404 work together. The connecting spring 402 absorbs the vertical vibration energy through extension and contraction, and the damping rod 403 suppresses the vibration amplitude through the viscous resistance of the internal damping medium, so that the up and down micro-movements of the support seat 404 are quickly attenuated, forming a composite protective structure to ensure that the equipment is protected from vibration damage during transportation or handling. The support frame 401 is fixed inside the box to provide rigid support for the entire protective assembly and ensure the stability of the structure during the buffering process.

[0030] Specifically, such as Figure 4 As shown, the buffer assembly 5 includes a fixed frame 501 fixedly connected to the bottom of the toolbox body 1. Limiting slide rods 502 are fixedly connected to both sides of the top of the fixed frame 501, and supporting foot pads 503 are slidably connected to the bottom of the limiting slide rods 502.

[0031] Specifically, such as Figure 4 As shown, a fixed base 504 is fixedly connected to the inner side of the support foot pad 503. A limiting slider 505 is fixedly connected to the top of the fixed base 504. A limiting connecting rod 506 is slidably connected to the top of the limiting slider 505. The limiting connecting rod 506 is fixedly connected to the fixed frame 501.

[0032] Specifically, such as Figure 4 As shown, a buffer spring assembly 507 is fixedly connected inside the fixed frame 501, and the bottom of the buffer spring assembly 507 is fixedly connected to the fixed base 504.

[0033] In this embodiment: when the toolbox is placed on the ground or subjected to a drop impact, the support foot 503 at its bottom first contacts the ground. The impact force is transmitted through the support foot 503 to the inner fixed seat 504. Then, the fixed seat 504 drives the top limiting slider 505 to slide upward along the limiting connecting rod 506, while compressing the buffer spring group 507 inside the fixed frame 501. The buffer spring group 507 is composed of multiple helical springs connected in parallel. It absorbs the impact energy through elastic deformation and converts the kinetic energy into the elastic potential energy of the spring. At the same time, its limiting slider 502 is slidably connected to the support foot 503, restricting it to move only in the vertical direction to prevent the toolbox from tilting. Moreover, the limiting connecting rod 506, through sliding cooperation with the limiting slider 505, constrains the displacement trajectory of the fixed seat 504 in the horizontal direction, ensuring the stability of the buffering process and achieving durable and reliable shock absorption protection.

[0034] Specifically, such as Figure 6 As shown, a rotating seat 3 is fixedly connected to the outer side of the top cover 2, and a fixed locking block 6 is rotatably connected to the inner side of the rotating seat 3. A connecting lock seat 7 is fixedly connected to the outer side of the toolbox body 1, and a fixed support rod 8 is inserted into the outer side of the connecting lock seat 7. The fixed support rod 8 is engaged with the fixed locking block 6.

[0035] Specifically, such as Figure 5 As shown, a tool box 9 is slidably connected inside the toolbox body 1. A limiting plate 10 is fixedly connected inside the tool box 9. A slot 11 is opened inside the limiting plate 10. A rod-shaped fixing ring 12 is engaged inside the slot 11. A rod-shaped limiting ring 13 is fixedly connected inside the limiting plate 10. A partition 14 is fixedly connected inside the limiting plate 10. A pull rod 15 is fixedly connected outside the tool box 9.

[0036] In this embodiment: by setting a rotating seat 3, a fixed locking block 6, a connecting locking seat 7, and a fixing rod, when it is necessary to close the top cover 2, first rotate the rotating seat 3 on the outside of the top cover 2, and then drive the fixed locking block 6 to rotate to the position opposite to the connecting locking seat 7 on the outside of the toolbox body 1. Insert the fixing rod 8 into the insertion hole on the outside of the connecting locking seat 7, so that the fixing rod 8 is engaged in the groove of the fixed locking block 6, so as to achieve a firm lock between the top cover 2 and the box body, preventing the top cover 2 from being accidentally opened during transportation. By setting a tool placement box 9, a limiting plate 10, a slot 11, a rod-shaped fixing ring 12, a rod-shaped limiting ring 13, a partition 14, and a pull rod 15, by pulling the pull rod 15 on the outside of the tool placement box 9, it can be smoothly pulled out from the inside of the toolbox body 1. The partition 14 inside 9 divides the space into multiple independent areas for storing non-rod-shaped tools such as measuring tools. When storing rod-shaped tools such as screwdrivers, first push the front end of the tool along the inner side of the limiting plate 10 so that the lower end of the tool is aligned with the rod-shaped limiting ring 13 and inserted into its bottom groove to restrict the lateral movement of the tool. Then insert the rod-shaped fixing ring 12 into the slot 11 of the limiting plate 10. Then, the top of the rod-shaped fixing ring 12 locks the upper end of the tool. The longitudinal fixation of the tool is achieved through the locking structure of the slot 11 and the rod-shaped fixing ring 12. This design, with double upper and lower limiting, prevents rod-shaped tools from falling off due to shaking during transportation. At the same time, the partition design of the partition 14 enables the orderly storage of tools. During maintenance, the storage box can be quickly pulled out by the pull rod 15 to improve the efficiency of tool retrieval.

[0037] Specifically, such as Figure 2 As shown, a positioning groove 16 is provided on the top of the toolbox body 1, and a positioning rod 17 is fixedly connected to the bottom of the top cover 2. The positioning rod 17 is slidably connected to the positioning groove 16.

[0038] Specifically, such as Figure 2 As shown, a sealing gasket 18 is embedded in the bottom of the top cover 2, and the sealing gasket 18 is made of rubber.

[0039] In this embodiment: by setting the positioning groove 16 and the positioning rod 17, when the top cover 2 is opened or closed, the positioning rod 17 at the bottom of the top cover 2 slides along the positioning groove 16 at the top of the toolbox body 1, ensuring the smooth sliding of the top cover 2. The positioning rod 17 is limited by the groove wall, ensuring that the top cover 2 is accurately aligned when closed, avoiding displacement that could lead to sealing failure. In bumpy environments, it can prevent the top cover 2 from being misaligned due to shaking. By setting the sealing gasket 18, when the top cover 2 is closed, the rubber sealing gasket 18 embedded in its bottom contacts and is squeezed against the top surface of the toolbox body 1. The rubber material has good elasticity and flexibility. Under pressure, the sealing gasket 18 deforms, filling the tiny gap between the top cover 2 and the box body, effectively preventing dust and moisture from entering the box and providing a sealed and protective environment for the internal equipment.

[0040] Working principle: When using this multi-functional toolbox to inspect the automatic protection equipment for train entry, first open the top cover 2. The top cover 2 is slidably connected to the positioning groove 16 on the top of the toolbox body 1 via the positioning rod 17, ensuring precise positioning when opening and closing. Simultaneously, the rubber sealing gasket 18 embedded at the bottom of the top cover 2 effectively prevents dust and moisture from entering the box after closing, providing a sealed and protective environment for the internal equipment. When placing precision maintenance equipment, first grasp the adjusting seat 409 and slide it outward along the limiting support rod 405. The adjusting seat 409 causes the protective clamps 407 on both sides to move accordingly, thereby widening the gap between the two protective clamps 407 to facilitate the placement of the maintenance equipment. During the movement of the adjusting seat 409, the protective clamps 407 on both sides of the limiting support rod 405... The compression spring 406 is compressed by an outward thrust, storing elastic potential energy. Simultaneously, the limiting support rod 405 provides a stable guide trajectory for the movement of the protective clamp 407, preventing it from deviating. When the equipment under maintenance is placed on top of the support base 404, the adjusting seat 409 is released. The compression spring 406, due to its elastic return, moves the protective clamp 407 inward. At this time, the rubber pad 408 on the inner side of the protective clamp 407 is tightly fitted to the equipment surface. On the one hand, it secures the equipment through elastic compression; on the other hand, the buffering performance of the rubber pad 408 reduces the direct impact on the equipment. When the equipment is subjected to external vibration, the support base 404 can move slightly up and down along the damping rod 403, causing the connecting spring 402 to extend and retract accordingly. Simultaneously, the damping rod 403 suppresses the vibration amplitude, forming a vertical... The compression spring 406 and protective clamp 407 provide horizontal cushioning and limit the equipment. This multi-dimensional cushioning structure works together to effectively protect the precision equipment from vibration damage during transportation or operation. When the toolbox is impacted by the ground or placed on an uneven surface, the support foot 503 contacts the ground first. The impact force is transmitted through the support foot 503 to the fixed seat 504. The fixed seat 504 drives the limiting slider 505 to slide upwards along the limiting connecting rod 506. Simultaneously, the buffer spring group 507 inside the fixed frame 501 is compressed. The buffer spring group 507, composed of multiple springs, absorbs impact energy through elastic deformation. Its limiting slider 502 and limiting connecting rod 506 limit the support in the vertical and horizontal directions, respectively. The movement trajectory of the foot pad 503 ensures that it can only slide up and down along the limiting slide bar 502, preventing the toolbox from tilting or shaking violently, thus protecting the equipment inside. During the compression and reset of its buffer spring assembly 507, the sliding cooperation between its limiting slider 505 and the limiting connecting rod 506 limits the movement of the supporting foot pad 503, making the buffering effect more uniform and effectively reducing the impact of ground impact on the toolbox. When using the tool storage box 9, pulling the outer lever 15 can pull it out or push it in. Its partition 14 divides the space inside the box into multiple compartments for classifying and storing different tools. When storing rod-shaped tools such as screwdrivers, first place the front end of the tool inside the limiting plate 10, align one end of the tool with the rod-shaped limiting ring 13, and slide it along the limiting ring to its bottom.Then, the rod-shaped fixing ring 12 is inserted into the slot 11. The locking structure between the rod-shaped fixing ring 12 and the slot 11 fixes the upper end of the tool, while the rod-shaped limiting ring 13 restricts the position of the lower end of the tool. This double fixing prevents the tool from shaking or falling off during transportation, thus achieving orderly classification and storage of tools and improving retrieval efficiency.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
