Description

Technical Field

[0001] This application relates to the field of railway communication technology, and in particular to a toolkit. Background Technology

[0002] In the field of railway communication technology, maintenance personnel often need to carry tool bags along railway lines for inspection and maintenance work. To facilitate movement, existing tool bags typically have wheels at the bottom, allowing them to be easily moved by personnel. However, once moved to the work location, these tool bags often lack an effective positioning structure, relying solely on the contact between the wheels and the ground to maintain stability. They are prone to displacement under slight external forces or on uneven ground, affecting not only the ease of loading and unloading tools but also potentially causing internal tools to collide and be damaged due to bag movement, demonstrating a significant lack of stability. Utility Model Content

[0003] Therefore, it is necessary to provide a toolkit to solve the technical problem that existing wheeled toolkits lack effective fixation after being moved into place and are prone to displacement, thereby achieving a balance between convenient movement and stable support.

[0004] A tool kit includes a bag body and a roller disposed at the bottom end of the bag body, the tool kit further including:

[0005] A support base is slidably fitted onto the package body along a first direction, where the first direction is the height direction of the package body;

[0006] A limiting frame, slidably fitted onto the package body along a second direction perpendicular to the first direction; one of the support base and the limiting frame is provided with a first sliding groove, and the other is connected to a first sliding shaft, the first sliding shaft passing through the first sliding groove, the extension direction of the first sliding groove being inclined relative to the first direction; and

[0007] A driving component is installed on the package body, the driving component is connected to the limiting frame, and is used to drive the limiting frame to move along the second direction, so as to drive the support base to rise and fall along the first direction.

[0008] In some embodiments, the first slide is disposed on the limiting frame, and the tool kit includes two connecting plates connected to the support base. The two connecting plates are respectively disposed on both sides of the limiting frame along a third direction and are correspondingly connected to both ends of the first slide shaft. Any two of the third direction, the second direction, and the first direction are perpendicular to each other.

[0009] In some embodiments, the tool kit includes a slider that slides along the first direction and engages with the bag body. The slider is provided with a locking bead, and the bag body is provided with at least two sets of slots arranged along the first direction. When the slider slides along the first direction to a preset position, the locking bead elastically engages with the corresponding slot.

[0010] In some embodiments, the toolkit includes a slide bar having a first state locked to the slider and a second state unlocked from the slider; in the second state, the slide bar is slidably engaged with the slider along the first direction.

[0011] In some embodiments, the tool kit includes a locking member rotatably connected to the slide bar, the locking member being configured to be operably rotated to engage or disengage with the slide bar; in a first state, the locking member and the slide bar are engaged; in a second state, the locking member and the slide bar are disengaged.

[0012] In some embodiments, the tool kit includes an operating lever resiliently connected to the slide, and a locking member connected to the operating lever; the operating lever is capable of being held in a locked position under the action of an elastic force, so that the locking member and the slide are locked together; the operating lever is configured to be operablely pressed to overcome the elastic force to reach an unlocked position, so as to rotate the locking member to separate from the slide.

[0013] In some embodiments, the slider is provided with a locking groove, the locking member has a second sliding groove, the operating lever is provided with a second sliding shaft, and the second sliding shaft passes through the second sliding groove; when the operating lever is held in the locked position, the locking member is inserted into the locking groove; during the process of the operating lever moving from the locked position to the unlocked position, it can drive the locking member to rotate through the second sliding shaft to exit the locking groove.

[0014] In some embodiments, the slider is provided with a plurality of locking grooves spaced apart along the first direction.

[0015] In some embodiments, the kit includes a drawer slidably connected to the kit body, the drawer having a latch resiliently connected thereto; the latch is capable of engaging with the kit body under elastic force; the latch is configured to be operably pressed to disengage from the kit body.

[0016] In some embodiments, the kit includes a plurality of drawer groups arranged along the first direction, each drawer group including at least two drawers at the same height.

[0017] In some embodiments, the toolkit includes a storage box that is attached to the body of the bag and has multiple partitions inside.

[0018] The aforementioned toolkit, once moved to the work position, has its driving mechanism push the limiting frame to move horizontally in the second direction. Utilizing the cooperation of the inclined first slide groove and the first sliding shaft, the horizontal driving force is converted into the vertical lifting motion of the support seat, causing it to descend stably below the rollers. This securely lifts the toolkit off the ground, eliminating the risk of roller slippage and effectively preventing the toolkit from sliding. This achieves a seamless transition from convenient movement to stable support. When movement is needed, the opposite operation retracts the support seat, allowing the rollers to contact the ground alone and resume flexible movement. This design cleverly fulfills the dual requirements of "flexible movement and stable operation," fundamentally solving the technical problems of traditional toolkits being prone to displacement and having poor stability.

[0031] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0032] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0033] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0037] See Figures 1 to 4 The toolkit provided in one embodiment of this application includes a bag body 110, which constitutes the main structure of the toolkit. A roller 120 (for example, a universal wheel; in the embodiment shown in the figure, a roller 120 is provided at each of the four corners of the bottom of the bag body 110) is installed at the bottom to facilitate the overall movement of the toolkit.

[0038] The toolkit provided in one embodiment of this application further includes a support base 211, a limiting frame 220, and a driving member 230. The support base 211 is slidably fitted to the bag body 110 along a first direction, which is the height direction of the bag body 110. The limiting frame 220 is slidably fitted to the bag body 110 along a second direction, which is perpendicular to the first direction. Of the support base 211 and the limiting frame 220, one is provided with a first sliding groove 221, and the other is connected to a first sliding shaft 213. The first sliding shaft 213 passes through the first sliding groove 221, and the extension direction of the first sliding groove 221 is inclined relative to the first direction. The driving member 230 is mounted on the bag body 110, connected to the limiting frame 220, and used to drive the limiting frame 220 to move along the second direction, thereby causing the support base 211 to rise and fall along the first direction.

[0039] In the toolkit described in the above embodiment, after the toolkit is moved to the work position, the drive unit 230 pushes the limiting frame 220 to move horizontally in the second direction. Utilizing the cooperation of the inclined first slide groove 221 and the first slide shaft 213, the horizontal driving force is converted into the vertical lifting motion of the support base 211, causing the support base 211 to descend stably to a position below the roller 120. This securely lifts the bag body 110 off the ground, eliminating the risk of roller 120 slippage and effectively preventing the bag body 110 from sliding, achieving a seamless switch from convenient movement to stable support. When movement is needed, the support base 211 can be retracted by reversing the operation, allowing the roller 120 to contact the ground alone and resume flexible movement. This design cleverly achieves the dual requirements of "flexible movement and stable operation," fundamentally solving the technical problems of traditional toolkits being prone to displacement and having poor stability.

[0040] In some embodiments, the limiting frame 220 slides in a second direction with the package body 110 via a guide structure on its own or an additional guide rail. For example, in Figures 3 to 4 In the embodiment shown, the package body 110 is provided with a slide rail 240 that is fixedly connected to it and extends along the second direction. The top end of the limiting frame 220 is slidably connected to the slide rail 240 to realize the sliding cooperation between the limiting frame 220 and the package body 110 along the second direction.

[0041] Similarly, in some embodiments, the support 211 slides along the first direction to the package 110 via its own guide structure or an additional guide rail. The bottom end of the package 110 has a through hole 111 (e.g., ...). Figure 2 As shown), so that the support 211 can extend downward or retract upward.

[0042] In some embodiments, the driving component 230 is a component such as a cylinder, electric cylinder, hydraulic cylinder or electric push rod, and its power output end is fixedly connected to the limiting frame 220 to drive the limiting frame 220 to reciprocate along the second direction.

[0043] See Figures 3 to 4In some embodiments, the first slide groove 221 is disposed on the limiting frame 220, and the first slide shaft 213 is connected to the support seat 211.

[0044] Furthermore, in some embodiments, the toolkit includes two connecting plates 212 connected to the support base 211. The two connecting plates 212 are respectively disposed on both sides of the limiting frame 220 along a third direction and are correspondingly connected to both ends of the first sliding shaft 213. Any two of the third direction, the second direction, and the first direction are perpendicular. As mentioned above, the first direction is the height direction of the package body 110, and any two of the third direction, the second direction, and the first direction are perpendicular, so both the second direction and the third direction are located in the horizontal plane. From the perspective of the accompanying drawings, one of the second direction and the third direction is the length direction of the package body 110, and the other is the width direction of the package body 110.

[0045] In the above embodiment, the force-bearing points of the first sliding shaft 213 are symmetrically arranged on both sides of the limiting frame 220 by two connecting plates 212, forming a stable double-support structure. This effectively avoids uneven loading, jamming, or tilting of the support seat 211 during lifting due to uneven force, ensuring smooth and stable lifting action and improving the rigidity and service life of the entire mechanism. In addition, the two connecting plates 212 and the first sliding shaft 213 form a "door"-shaped frame structure, "embracing" the limiting frame 220 in the middle, making the mechanism more compact and stable.

[0046] Specifically, in some embodiments, both connecting plates 212 are located at the top of the support base 211. The connecting plates 212 can be integrally formed with the support base 211, or they can be fixed by welding, riveting, or bolting. The two connecting plates 212 and the two ends of the first sliding shaft 213 are fixedly connected to each other, and the fixing method can be welding, riveting, or bolting.

[0047] In some embodiments, the bottom of the support base 211 may be provided with an anti-slip pad made of materials such as rubber or silicone to increase friction with the ground and further improve stability.

[0048] When the tool kit needs to be fixed in one place, the drive unit 230 is activated, which drives the limiting frame 220 to move along the second direction. The first groove 221 on the limiting frame 220 guides and limits the first sliding shaft 213. When the limiting frame 220 moves, the first sliding shaft 213 slides relative to the first groove 221. Since the extension direction of the first groove 221 is inclined relative to the first direction, the first sliding shaft 213, driven by the horizontal movement component, also generates a vertical displacement, which in turn drives the support base 211 to slide up and down along the first direction within the package body 110 through the connecting plate 212.

[0049] The package body 110 guides and limits the sliding of the support base 211 through structures such as guide rails and guide posts, ensuring that the support base 211 always rises and falls smoothly along the height direction of the package body 110. When the first sliding shaft 213 slides to one end of the first sliding groove 221, the support base 211 moves to the lowest point of its stroke. At this time, the bottom surface of the support base 211 is lower than the bottom surface of the roller 120, causing the package body 110 to be lifted off the ground, and the support base 211 then provides stable support for the entire tool bag, effectively preventing the tool bag from shifting during operation and improving the safety and stability of use.

[0050] In other embodiments, the first slide groove 221 may be disposed on the support base 211, and the first slide shaft 213 may be connected to the limiting frame 220.

[0051] See Figures 5 to 7 In some embodiments, the tool kit includes a slider 310 that slides along a first direction and engages with the body 110. The slider 310 is provided with a locking bead 321, and the body 110 is provided with at least two sets of slots 112 arranged along the first direction. When the slider 310 slides along the first direction to a preset position, the locking bead 321 elastically engages with the corresponding slot 112.

[0052] Specifically, the "preset position" includes at least two states: the slider 310 is fully extended and fully retracted, and the number and position of the slots 112 are set accordingly.

[0053] In the above embodiment, a retractable handle structure is achieved through the sliding engagement of the slider 310 and the bag body 110. When the tool bag needs to be moved, the user can pull the slider 310 upward from the bag body 110, placing it in a higher, easier-to-grip position, thus making it easier to drag the tool bag. When the tool bag is moved to the work site or needs to be stored, the slider 310 can be pushed back into the bag body 110 to reduce the overall volume, making it easier to store and work. Furthermore, through the engagement of the locking bead 321 with the locking slots 112 at different positions, a clear sense of positioning and a precise positioning effect are provided when the user pushes or pulls the slider 310 to the end of its stroke (such as fully extended or fully retracted), preventing it from sliding on its own during movement or work, thus improving the convenience and stability of use.

[0054] In some embodiments, the package body 110 has a guide groove 114 extending along a first direction, and the slider 310 is slidably mounted in the guide groove 114. A portion of the sidewall of the guide groove 114 is recessed to form a slot 112. The retaining bead 321 and the slider 310 are connected by a first elastic member 322. The elastic force of the first elastic member 322 causes the retaining bead 321 to tend to extend outward and protrude from the slider 310. During the sliding stroke of the slider 310, when the retaining bead 321 reaches other areas outside the slot 112, it will elastically abut against the sidewall of the guide groove 114, and the first elastic member 322 will be compressed; when it reaches the slot 112, the retaining bead 321 will be pushed outward by the first elastic member 322 and snap into the slot 112.

[0055] Furthermore, the ball 321 is a steel ball, and the groove 112 is a matching hemispherical groove.

[0056] Preferably, in some embodiments, two sets of retaining beads 321 and a first elastic member 322 are symmetrically arranged on the slider 310. These two sets of retaining beads 321 are respectively disposed on both sides of the slider 310. Correspondingly, two slots 112 are also provided at each preset position on the side walls of the guide groove 114 of the package body 110. When the slider 310 slides to the preset position, the retaining beads 321 on both sides can simultaneously and symmetrically engage with their respective slots 112.

[0057] The symmetrical arrangement of the locking beads 321 and the locking slots 112 ensures that the slider 310 receives balanced positioning force from both sides at any preset position. This not only eliminates the torque that may be generated by unilateral positioning, ensuring the smooth and stable movement and positioning of the slider 310, but also effectively enhances its structural rigidity and load-bearing capacity in the pulled-out state through double-sided locking, making the handle function more stable and durable.

[0058] See Figure 1 ,as well as Figures 5 to 7 In some embodiments, the tool kit includes a slide bar 330 having a first state locked to a slider 310 and a second state unlocked from the slider 310; in the second state, the slide bar 330 is slidably engaged with the slider 310 along a first direction.

[0059] This embodiment, based on the aforementioned retractable slider 310, further introduces a retractable lever 330 relative to the slider 310, forming a two-stage retractable handle system. When using only the slider 310 as a handle still feels insufficient in height, the user can switch the lever 330 from the first state to the second state, thereby pulling the lever 330 further upward from the slider 310, extending the effective length of the overall handle. This design improves the user's comfort and effort-saving effect when dragging a tool bag, and better adapts to the needs of users of different heights. If extension is not required, the lever 330 can be kept in the first state (locked).

[0060] In some embodiments, the slide bar 330 may include a middle portion 332, a base portion 331 connected to the bottom end of the middle portion 332, and a handle portion 333 connected to the top end of the middle portion 332. The base portion 331 is slightly larger than the middle portion 332, and the base portion 331 slides in conjunction with a hole 312 provided in the slider 310 to achieve the extension and retraction of the slide bar 330. The handle portion 333 facilitates gripping by the user.

[0061] See Figures 5 to 7 In some embodiments, the tool kit includes a locking member 340 rotatably connected to the slide bar 330, the locking member 340 being configured to be operably rotated to engage or disengage from the slide bar 310; in a first state, the locking member 340 and the slide bar 310 are engaged and locked; in a second state, the locking member 340 and the slide bar 310 are disengaged.

[0062] In the above embodiments, the locking member 340 is connected to and separated from the sliding member 310 by rotating the locking member 340, thereby achieving the locking and unlocking of the sliding rod 330 and the sliding member 310. When unlocking or locking is required, the user can directly rotate the locking member 340, or indirectly rotate the locking member 340 through other structures in subsequent embodiments (such as the operating lever 350).

[0063] See Figures 5 to 7 In some embodiments, the tool kit includes an operating lever 350 resiliently connected to a slide bar 330, and a locking member 340 connected to the operating lever 350; the operating lever 350 is capable of being held in a locked position under the action of an elastic force, so that the locking member 340 and the slide bar 310 are locked together; the operating lever 350 is configured to be operablely pressed to overcome the elastic force to reach an unlocked position, so as to rotate the locking member 340 to separate it from the slide bar 310.

[0064] In the above embodiment, an operating lever 350 with an automatic reset function is integrated, and the unlocking action of the slide bar 330 is simplified to a single press operation, greatly improving the user experience. The user only needs to press the operating lever 350 with one hand while simultaneously pushing and pulling the handle 333 to unlock the slide bar 330 and adjust its length. After releasing the operating lever 350, it automatically resets under the action of elastic force, reconnecting and locking the locking member 340 and the slide member 310. The operation is highly efficient and quick.

[0065] Specifically, the operating lever 350 includes an optical shaft portion 353 and a pressing portion 352 connected to the top of the optical shaft portion 353. The optical shaft portion 353 is inserted into the slide bar 330, and its bottom end is connected to the locking member 340. A second elastic member 360 is sleeved on the outside of the optical shaft portion 353. The top end of the second elastic member 360 abuts against the pressing portion 352, and the bottom end abuts against the handle portion 333 of the slide bar 330. Under the elastic force of the second elastic member 360, the operating lever 350 is pushed upward and maintained in the locked position. When the pressing portion 352 is pressed, the optical shaft portion 353 will drive the locking member 340 connected to it to rotate, thereby unlocking the lever.

[0066] See Figures 5 to 7 In some embodiments, the slider 310 is provided with a locking groove 311, the locking member 340 has a second sliding groove 3411, and the operating lever 350 is provided with a second sliding shaft 351, which passes through the second sliding groove 3411. When the operating lever 350 is held in the locked position, the locking member 340 is inserted into the locking groove 311. During the process of the operating lever 350 moving from the locked position to the unlocked position, the second sliding shaft 351 can drive the locking member 340 to rotate and exit the locking groove 311.

[0067] In the above embodiment, the linear motion of the operating rod 350 is converted into the rotational motion of the locking member 340 by the sliding of the second sliding shaft 351 in the second sliding groove 3411. The transmission efficiency is high, and reliable unlocking can be achieved with a small pressing force. The structure is compact and the working process is stable and reliable.

[0068] Furthermore, a pivot 3312 is provided within the base portion 331 of the slide bar 330. A locking member 340 is rotatably connected to the pivot 3312, with its two ends (first end 341 and second end 342) positioned on either side of the pivot 3312, making the locking member 340 resemble a lever. A second sliding groove 3411 is formed at the first end 341. A second sliding shaft 351 is connected to the bottom region of the optical shaft portion 353, passing through and slidingly engaging with the second sliding groove 3411. A portion of the sidewall of the hole 312 within the slide member 310 is recessed to form a locking groove 311. A notch 3311 is formed in the sidewall of the base portion 331 of the slide bar 330 to provide space for the rotation of the locking member 340.

[0069] When the extension length of the slide bar 330 needs to be adjusted, the user presses down on the pressing part 352 of the operating lever 350, compressing the second elastic element 360 and causing the second sliding shaft 351, fixed to the optical shaft part 353, to move downwards simultaneously. Since the second sliding shaft 351 passes through the second sliding groove 3411 opened on the first end 341 of the locking member 340, the downward movement of the optical shaft part 353 forces the second sliding shaft 351 to slide relative to the second sliding groove 3411. This sliding action causes the locking member 340 to rotate with its pivot 3312 as the fulcrum, and the second end 342 of the locking member 340 subsequently disengages from the locking groove 311 of the sliding member 310, completing the unlocking process. Simultaneously, the user pushes or pulls the handle part 333 of the slide bar 330, allowing it to slide freely within the hole 312 of the sliding member 310, adjusting it to the appropriate position. After adjustment, release the pressing part 352 of the operating lever 350. Under the reset force of the second elastic element 360, the operating lever 350 springs back upward and drives the locking element 340 to rotate in the opposite direction through the cooperation of the second sliding shaft 351 and the second sliding groove 3411. If the second end 342 has reached a certain locking groove 311 at this time, it will directly lock into the locking groove 311. (Preferably, multiple scale lines can be set on the sliding rod 330 to correspond to different gears. When the sliding rod 330 extends or retracts, its scale lines are aligned with specific marking positions on the sliding element 310 to ensure that the second end 342 has reached a certain locking groove 311 at this time.)

[0070] If there is a certain gap between the second end 342 and the nearest second end 342 at this time, the second end 342 will press against the side wall of the hole 312 with a certain preload. When the user fine-tunes the position of the slide bar 330 so that the second end 342 is aligned with the nearest locking groove 311, the second end 342 will be instantly sprang into the locking groove 311 under the continuous drive of the second elastic element 360, accompanied by a clear "click" sound or tactile sensation, thus completing the locking.

[0071] See Figures 5 to 7 In some embodiments, the slider 310 is provided with a plurality of locking grooves 311 arranged at intervals along a first direction.

[0072] In the above embodiments, by setting multiple locking slots 311, multiple discrete and fixed locking positions are provided for the extension and retraction of the slide bar 330 relative to the sliding member 310. This allows the overall length of the aforementioned two-stage extendable handle to be adjusted in multiple levels, and users can fix the handle length in the most suitable position according to their own height and operating habits, achieving a more refined human-machine adaptation.

[0073] Specifically, each locking slot 311 corresponds to a specific extension length of the slide bar 330. When the slide bar 330 extends or retracts, the second end 342 of the locking member 340 can be engaged in locking slots 311 at different heights, and the spacing of the locking slots 311 determines the accuracy of the length adjustment.

[0074] See Figures 8 to 10 In some embodiments, the tool kit includes a drawer 410 slidably connected to the body 110, the drawer 410 having a latch 412 elastically connected thereto; the latch 412 is capable of engaging the body 110 under elastic force; the latch 412 is configured to be operably pressed to disengage the body 110.

[0075] Specifically, the drawer 410 and the inner wall of the bag body 110 can achieve a sliding fit through a guide structure such as a slide rail, slider, guide post, and guide sleeve. The drawer 410 can store various tools and parts needed for maintenance. The drawer 410 is equipped with a handle 411 for easy pulling out.

[0076] In the above embodiment, an automatic locking function is added to drawer 410. This structure can effectively prevent drawer 410 from accidentally sliding open due to vibration or tilting during the movement, handling, or operation of the tool bag, avoiding the scattering and loss of internal tools and parts, and improving the safety and convenience of use.

[0077] Furthermore, the latch 412 is elastically connected to the drawer 410 via a third elastic element 413. For example, the drawer 410 has a sliding column 415 that can slide up and down inside. The top end of the sliding column 415 is fixedly connected to the latch 412, and the bottom end is fixedly connected to the sliding piece 414 exposed outside the drawer 410. The third elastic element 413 is sleeved on the outside of the sliding column 415, and the top end of the third elastic element 413 is connected to the latch 412, and the bottom end is connected to the drawer 410. The elastic force of the third elastic element 413 causes the latch 412 to tend to pop up and engage with the slot provided on the bag body 110. When it is necessary to unlock the drawer 410, simply press the sliding piece 414, and the latch 412 can be pulled out of the slot provided on the bag body 110 by the sliding column 415. At this time, the drawer 410 can be pulled out for tools to be retrieved.

[0078] Preferably, the latch 412 is wedge-shaped or hemispherical, so that it can be automatically pressed into the edge of the bag body 110 when the drawer 410 is closed, and automatically pop out and lock after being aligned with the slot in the bag body 110.

[0079] See Figures 8 to 10 In some embodiments, the kit includes a plurality of drawer groups 400 arranged along a first direction, each drawer group 400 including at least two drawers 410 at the same height.

[0080] This design greatly optimizes the utilization of the toolkit's internal space. It allows for the meticulous categorization and storage of a wide variety of railway communication tools and parts, ensuring organized tool management and facilitating quick location and retrieval of necessary items by inspection personnel, thus significantly improving on-site operational efficiency.

[0081] Combination Figure 8 and Figure 10 For example, a tool kit can be configured with three drawer groups 400 (top, middle, and bottom). Each drawer group 400 can contain two drawers 410, with the two drawers 410 in each layer pulling out in opposite directions. Different types of tools can be stored in drawers on different layers and in different locations, achieving functional zoning.

[0082] See Figure 8 and Figure 10 In some embodiments, the tool kit includes a storage box 500, which is attached to the bag body 110 and has multiple partitions 510 inside.

[0083] In the above embodiments, the hanging design makes the storage box 500 easy to access and convenient for individual use or cleaning. The internal dividers 510 allow users to customize the space according to the size and shape of the small, precision parts stored, achieving ultimate neatness and order, and improving space utilization and tool management flexibility.

[0084] Combination Figure 8 and Figure 10 The storage box 500 is hooked onto the corresponding hanging slots 113 inside the bag body 110 via two symmetrical hanging parts 520 provided on its outer wall. The partition 510 can be a movable partition that is inserted into a preset slot in the bottom plate of the storage box 500, and the user can freely combine the partition schemes as needed. The entire storage box 500 can be removed from the bag body 110 as an independent module for use.

[0085] In some embodiments, the storage box 500 is disposed in the top space inside the bag body 110. The top of the bag body 110 may also be provided with a dustproof panel 140 that can be flipped up and down. By flipping the dustproof panel 140 upward, the storage box 500 can be exposed for easy access to tools. After the tools are accessed, the dustproof panel 140 can be flipped downward to provide protection.

[0086] See Figure 1 In some embodiments, the outer wall of the bag body 110 is also fixed with a shoulder strap 130 so that the user can lift or carry it by means of the shoulder strap 130.

[0087] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
