[0031] Please refer to Figures 1 to 3 As shown, this utility model provides a quick-release support rack for supporting circuit breakers mounted on a chassis vehicle.

[0032] Specifically, the quick-release load-bearing shelf includes a multi-layer shelf 1, a sleeve fastening assembly 4, and a pressure monitoring assembly. Each shelf 1 includes a frame 11 and a shelf 12. Adjacent shelf 1s are detachably and fixedly connected. The shelf 12 is detachably and fixedly installed on the frame 11 for supporting objects. The shelf 12 is provided with a limiting assembly 3 to limit the displacement of objects. The bottom of the multi-layer shelf 1 is detachably installed with a support leg 2. The sleeve fastening assembly 4 is fixedly installed on the top and bottom of each frame 11 for detachably and fixedly connecting adjacent frame 11s and the frame 11 and the support leg 2. The pressure monitoring assembly includes a pressure monitoring element and an alarm element. The pressure monitoring element is installed between each support leg 2 and the frame 11. The pressure monitoring element and the alarm element are electrically connected. When the pressure monitored by the pressure monitoring element exceeds the rated pressure range, the alarm element can sound an alarm.

[0033] By employing a design where adjacent shelf units 1, shelf panels 12, and support legs 2 are all detachably and securely connected, the shelving unit can be freely combined and adjusted in terms of the number of layers to adapt to different storage needs. Simultaneously, when the shelving unit is not in use or needs to be moved, it can be disassembled for storage and transport, saving space and improving the convenience of storage and handling. A sleeve fastening assembly 4 ensures a reliable connection between adjacent shelf units 1 and between the bottom layer of multi-layer shelf units 1 and the support legs 2, ensuring the overall structural stability. This facilitates installation and disassembly, effectively enhances load-bearing capacity, and prevents loosening or tilting. By setting limiting components 3 on the shelf panels 12, the displacement of stored items can be effectively restricted, preventing items from sliding during storage and thus avoiding the risk of shelf panel deformation or shelving tipping due to uneven stress. By installing pressure monitoring devices between each support leg 2 and the bottom layer of the multi-layer shelf 1, and electrically connecting these devices to an alarm mechanism, the stress on each support leg 2 can be monitored in real time. If the load on any support leg 2 exceeds its rated range, or if all support legs 2 are overloaded, the alarm will automatically sound, alerting the operator to the risk of uneven stress or overloading on the shelf. This allows for emergency measures to be taken before a hazard occurs, effectively preventing the shelf from tipping over or the shelves 12 from deforming, improving storage safety and reliability, and extending the shelf's lifespan.

[0034] Combination Figure 1 and Figure 3 As shown, specifically, the frame 11 includes a rectangular frame 111 and multiple uprights 112. The multiple uprights 112 are arranged around the top outer edge of the rectangular frame 111 and are positioned opposite to the sleeve fastening components 4 at the bottom of the adjacent shelf 1. One end of the upright 112 is connected to the rectangular frame 111, and the other end is detachably and fixedly connected to the sleeve fastening components 4 on the adjacent shelf 1. Shelves 12 are installed on the rectangular frame 111. The rectangular frame 111 serves as the main support structure, forming a closed structure with four horizontal bars. The four sides can share the stress, effectively improving the load-bearing capacity. One end of the upright 112 is connected to the rectangular frame 111, and the other end is connected to the sleeve fastening components 4, which can provide better support and prevent shaking or tilting caused by loose connections, thus improving the overall stability. Shelves 12 are installed on the rectangular frame 111, providing stable support and preventing deformation of the shelves 12 due to uneven stress caused by shaking during the storage of items.

[0035] Optionally, the shelf 12 can be detachably and fixedly connected to the rectangular frame 111 by bolts, without being specifically limited here.

[0036] Optionally, the outer edge of the top of the rectangular frame 111 is provided with a plurality of sleeve fastening components 4. One end of the upright 112 can be detachably and fixedly connected to the rectangular frame 111 through the sleeve fastening components 4, and the other end can be detachably and fixedly connected to the sleeve fastening components 4 on the adjacent shelf 1.

[0037] In other embodiments, the upright 112 may be welded to the top of the rectangular frame 111, which is not specifically limited here.

[0038] like Figure 2 As shown, to make the shelving unit more robust and easier to assemble and disassemble, in some embodiments, the sleeve fastening assembly 4 includes a sleeve 41 and a fastener 42. The sleeve 41 is fixedly disposed at the bottom of the rectangular frame 111. The sleeve 41 is inserted into the upright 112 of the adjacent shelf 1, and the fastener 42 can penetrate the sleeve 41 to fasten the adjacent shelf 1 body. Alternatively, the sleeve 41 is inserted into the support leg 2, and the fastener 42 can penetrate the sleeve 41 to fasten the support leg 2 to the bottom of the multi-layer shelf 1. Operators can directly insert the upright 112 or support leg 2 into the sleeve 41, reducing the cumbersome alignment operations of traditional assembly. The fastener 42, penetrating the sleeve 41, fastens the adjacent shelf 1 body or the support leg 2 to the frame 11, allowing for installation and disassembly without complex tools, thus improving the shelving unit's detachability and flexibility. The simultaneous insertion of the sleeve 41 and the fastener 42 further strengthens the connection.

[0039] Specifically, each sleeve fastening assembly 4 includes at least two fasteners 42. At least two first positioning holes are spaced apart on the sleeve 41 along its length direction, and at least two second positioning holes are oppositely opened on the upright 112 and the support leg 2. The fasteners 42 can pass through the opposite first positioning holes and second positioning holes respectively to fasten the frame body 11, the support leg 2, and the adjacent shelf body 1. By setting at least two fastening points in the length direction of the sleeve 41 and reinforcing it with at least two fasteners 42, the torque can be effectively distributed, avoiding the stress concentration problem caused by a single fastener 42, improving the overall stability of the shelf, and preventing plastic deformation of the adjacent shelf body 1.

[0040] Optionally, the fastener 42 includes a bolt and a nut. One end of the bolt can pass through the corresponding first positioning hole and second positioning hole and be threadedly connected to the nut. Both the bolt and the nut abut against the sleeve 41. The mechanical connection between the bolt and the nut is strong and has a stronger load-bearing capacity, which can effectively cope with stress changes caused by long-term load.

[0041] In other embodiments, the fastener 42 includes a quick-release pin that can be quickly inserted into the first positioning hole and the second positioning hole to fasten the bottom of the multi-layer shelf 1, the support leg 2, and the adjacent shelf 1 body; wherein, the quick-release pin can be directly inserted into the positioning hole without the need for additional tools (such as wrenches or screwdrivers), which can greatly improve the speed of installation and disassembly.

[0042] like Figure 2As shown, optionally, the frame 11 also includes a reinforcing rib 13, which is located on the side of the rectangular frame 111 away from the shelf 12. The reinforcing rib 13 can effectively improve the bending and torsional resistance of the rectangular frame 111, evenly distribute the load borne by the rectangular frame 111, avoid deformation due to long-term bearing of the weight of the circuit breaker or external force, and extend the service life.

[0043] The reinforcing members can be arranged diagonally along the rectangular frame 111 to form an X-shaped structure or a grid-shaped structure, without specific limitations.

[0044] Combination Figure 1 and Figure 2 As shown, since the circuit breaker equipped with the chassis can slide on a plane, it may move under inertia or vibration if not restricted, resulting in excessive local stress or uneven stress distribution on the shelf 12, which may cause deformation of the shelf 12 or even affect the stability of the entire shelf. To solve the above problems, in some embodiments, the limiting component 3 includes two limiting slide rails 31. The two limiting slide rails 31 are detachably mounted on the shelf 12 and parallel to the edge of the rectangular frame 111. The limiting slide rails 31 form a fixed track, effectively limiting the lateral or longitudinal sliding of the circuit breaker, ensuring that the shelf 12 is subjected to uniform stress, and reducing the risk of deformation or tilting due to uneven loading. At the same time, since the limiting slide rails 31 are detachable, the operator can choose whether to install them according to storage needs. When the stored items do not need to be limited, the limiting slide rails 31 can be quickly removed to restore the complete usable space of the shelf 12.

[0045] Optionally, the limit guide rail can be fixedly connected to the shelf 12 by bolts, which is not specifically limited here.

[0046] like Figure 2 As shown, specifically, the limiting slide rail 31 has an L-shaped structure. One side of the limiting slide rail 31 is fixedly connected to the shelf 12, and the other side restricts the displacement of the circuit breaker. The L-shaped limiting slide rail 31 can be easily connected to the shelf 12, and the installation is simple.

[0047] More specifically, the limiting slide rail 31 is provided with limiting slots 32 spaced apart along its length to restrict the movement of objects along the length of the limiting slide rail 31; wherein, the limiting slots 32 can provide precise positioning and restrict the movement of the circuit breaker equipped with the chassis along the length of the limiting slide rail 31, ensuring that the circuit breaker always remains in a fixed position during storage, which can effectively prevent the circuit breaker from sliding out of the shelf 12 and reduce the risk of equipment falling and damage or safety accidents.

[0048] To provide a more intuitive feedback on pressure monitoring status, in some embodiments, the pressure monitoring component (not shown in the figure) also includes a data transmission device and a display. The pressure monitoring device, data transmission device, display, and alarm device are communicatively connected. Operators can directly view the real-time monitoring status of each pressure monitoring device through the display. When an alarm occurs, the display can intuitively show the specific location of the alarm, facilitating timely response by operators.

[0049] For example, support legs 2 are provided at the four corners of the bottom of the multi-layer shelf 1. Pressure monitoring devices are clamped between the four support legs 2 and the bottom of the multi-layer shelf 1. The pressure monitoring devices can be, but are not limited to, weighing sensors. The pressure monitoring devices, alarm devices, data transmission devices and displays are connected in communication. The displays can show the single-point load of the pressure at the four points in real time. When the single-point load of the pressure monitoring device is greater than 500 kg, the alarm device will be triggered. At this time, the display will show the point where the abnormality occurred, so that the operator can adjust the placement of the circuit breaker in time until the alarm is cleared.

[0050] Optionally, the data transmission device can be a Bluetooth module, which supports wireless transmission, making device connection simpler and more convenient. Furthermore, the Bluetooth module can connect to a mobile phone, allowing operators to monitor load distribution in real time via their phones, thus achieving more flexible and convenient pressure monitoring and management.

[0051] Optionally, the alarm device includes an audible and visual alarm. The audible and visual alarm can attract attention in a short time by emitting a loud alarm sound and flashing lights, ensuring that the alarm information can be received in a timely manner. Especially in noisy environments, the sound alarm can effectively break through the background noise, while the light alarm can make the warning signal visible to people at a distance.

[0052] In other embodiments, the alarm device may also be a voice alarm, which is not specifically limited here.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
