Description

Technical Field

[0001] This invention belongs to the field of hardware storage technology, and in particular to a hardware storage cabinet. Background Technology

[0002] In the production, processing, and use of hardware, hardware storage cabinets, as storage and conveying equipment, play a crucial role in classifying, storing, and retrieving hardware parts. A search of Chinese patent documents (application publication number CN108968433A) reveals a multifunctional hardware storage cabinet. Through the arrangement of storage boxes, tool drawers, magnets, and a secondary table mechanism, the cabinet offers greater storage space, allowing for orderly and categorized placement of hardware parts, enhancing convenience during use, and enabling the carrying of more tools. The secondary table can also be folded up and used as a workbench, making its functionality more diverse. Therefore, this hardware storage cabinet can meet people's needs. While this device can satisfy basic usage requirements, current hardware tool storage commonly suffers from the following problems: Poor security: the drawer is easy to slide out when moved, and the smart locking capability is weak; Finding items is difficult: Traditional cabinets require manual searching, which is inefficient; Inconvenient access: Heavy tools are difficult to retrieve and place, which can easily cause safety hazards; Hardware parts mixed with impurities: This contaminates the surface of the hardware parts, prevents the separation of impurities, and contaminates the tools.

[0003] In view of the core defects of the existing technology, there is an urgent need to design a technical solution with outstanding innovation to solve the shortcomings of the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide a hardware storage cabinet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hardware storage cabinet, comprising: The cabinet and the multi-layered storage units and two positioning identification modules installed inside the cabinet; The multi-layer storage unit includes a medium-sized storage compartment, an accessory drawer, a valuables cabinet, and multiple small storage compartments for storing hardware of different sizes and types. Each of the small storage compartments has a self-locking drawer slidably installed inside. A sliding column is fixedly connected to the end face of each self-locking drawer. A conical fixing block is installed at the end of the sliding column away from the self-locking drawer. A conical sliding block is slidably connected to the outer periphery of the sliding column, and the conical sliding block is slidably fitted onto the outer periphery of the sliding column. A transverse sliding groove is provided on the side of each small storage compartment to allow the sliding column, conical fixing block, and conical sliding block to enter.

[0006] Preferably, both the upper and lower sides of the transverse slide are provided with vertical slides for providing installation space for the positioning and identification modules. The two positioning and identification modules are symmetrically installed inside the vertical slides about the transverse slides. The positioning and identification module includes a pressure sensor bracket, a spring, a square slide plate, and a conical slider.

[0007] Preferably, the size of the conical sliding block is slightly larger than the size of the conical fixed block, which facilitates the conical slider to separate the conical fixed block from the conical sliding block and enter between the conical fixed block and the conical sliding block for locking the self-locking drawer in the small placement room.

[0008] Preferably, the end of the tapered slider is provided with a chamfer for sliding in contact with the tapered sliding block, and for disengaging from the position between the tapered fixed block and the tapered sliding block.

[0009] Preferably, the spring is used to provide the resetting capability of the conical slider. The spring is connected between the pressure sensor frame and the square slide plate. The pressure sensor frame is used to detect the force on the spring. A guide block is fixedly installed on the outer periphery of the square slide plate. A limiting block is installed at one end of the vertical slide groove near the horizontal slide groove to cooperate with the guide block and prevent the conical slider from dislodging from the interior of the vertical slide groove.

[0010] Preferably, the top of the cabinet is provided with two temporary placement slots, one of which is equipped with a separation net for separating hardware from impurities, and the two sides of the temporary placement slot are provided with cross grooves.

[0011] Preferably, the two cross slides are laterally slidably connected to each other, and a rotating column is rotatably connected between the two cross slides. A flexible scraper for cleaning impurities inside the temporary placement slot is installed on the outer periphery of the rotating column, and a rotating handle for easy operation is installed at one end of the rotating column.

[0012] Preferably, a vertical support is installed on the side of the cabinet, and a limiting frame and a placement frame are respectively installed on the upper and lower outer periphery of the vertical support. The surfaces of the limiting frame and the placement frame are provided with multiple placement holes for placing rod-shaped hardware.

[0013] Preferably, the valuables cabinet is equipped with a door and a security lock on its side.

[0014] Preferably, the bottom of the cabinet is equipped with multiple casters for easy movement, and the side of the cabinet is equipped with a push handle.

[0015] Compared with the prior art, the technical effects and advantages of the present invention are as follows: This hardware storage cabinet, thanks to the collaborative structure of the positioning and recognition module (pressure sensor bracket, spring, and conical slider) with self-locking drawers, sliding columns, conical fixing blocks, conical sliding blocks, and horizontal sliding grooves, effectively solves the problems of poor security, drawers easily sliding out when moved, and weak intelligent locking capabilities of traditional storage cabinets. The self-locking drawer can be accurately locked after being pushed in, and the drawer will not accidentally slide out when the cabinet is moved. The pressure sensor bracket can also monitor the locking status in real time, improving the reliability of intelligent locking and preventing hardware parts from falling and being damaged or causing safety hazards.

[0016] This hardware storage cabinet effectively solves the problems of difficult searching, manual rummaging, and low efficiency associated with traditional storage cabinets, thanks to its categorized storage structure consisting of a medium-sized storage compartment, accessory drawers, a valuables cabinet, and multiple small storage compartments. Hardware of different sizes and types can be stored separately, with small hardware corresponding to the self-locking drawers in the small storage compartments, medium-sized hardware to the medium storage compartments, and scattered accessories to the accessory drawers. This eliminates the need for manual searching and significantly improves the efficiency of finding and retrieving hardware.

[0017] This hardware storage cabinet, thanks to its multiple casters at the bottom, push handles on the sides, and layered storage unit structure, effectively solves the problems of inconvenient access, laborious handling of heavy tools, and potential safety hazards associated with traditional storage cabinets. By pushing the handles in conjunction with the casters, the cabinet can be moved flexibly, allowing heavy tools to be placed in the lower storage units, reducing the labor intensity of manual handling, avoiding safety hazards such as bumps and drops during transportation, and improving the convenience and safety of access.

[0018] This hardware storage cabinet, thanks to its structure of a temporary storage slot at the top and a separation net installed on top, effectively solves the problems of hardware and impurities mixing, contaminating the surface of hardware, and failing to separate impurities in traditional storage cabinets. When temporarily storing hardware, the separation net can quickly separate the hardware from the attached impurities. The hardware remains above the separation net, while the impurities fall to the bottom of the temporary storage slot, preventing impurities from contaminating the surface of the hardware and affecting the performance of the tools, while also facilitating subsequent impurity cleaning.

[0019] This hardware storage cabinet, thanks to the combined structure of vertical supports, limiting frames, placement racks, and placement holes, effectively solves the problems of messy storage and easy tipping and loss of rod-shaped hardware in traditional storage cabinets. The rod-shaped hardware can be inserted into the placement holes, and the limiting frames and placement racks achieve upper and lower limits and support, so that the rod-shaped hardware is stored in an orderly manner and is easy to access. At the same time, it saves internal space of the cabinet and further improves the space utilization rate of the storage cabinet. Attached Figure Description

Detailed Implementation

[0023] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0024] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0025] like Figures 1 to 7 The hardware storage cabinet shown includes: The cabinet 1 includes a multi-layer storage unit and two positioning identification modules. The multi-layer storage unit includes a medium-sized storage room 103, an accessory drawer 104, a valuables cabinet 105, and multiple small storage rooms 106 for storing hardware of different sizes and types. Each of the multiple small storage rooms 106 has a self-locking drawer 2 slidably installed inside. The end face of the self-locking drawer 2 is fixedly connected to a slide column 201. A conical fixing block 202 is installed at the end of the slide column 201 away from the self-locking drawer 2. A conical sliding block 203 is slidably connected to the outer periphery of the slide column 201. The conical sliding block 203 is slidably sleeved on the outer periphery of the slide column 201. The side of the small storage room 106 is connected to a transverse sliding groove 307 for providing entry for the slide column 201, the conical fixing block 202, and the conical sliding block 203. The upper and lower sides of the transverse slide 307 are provided with vertical slides 3 for providing installation space for the positioning and identification modules. The two positioning and identification modules are symmetrically installed inside the vertical slides 3 about the transverse slide 307. The positioning and identification modules include a pressure sensor bracket 301, a spring 302, a square slide plate 303 and a conical slider 304.

[0026] The tapered sliding block 203 is slightly larger than the tapered fixed block 202, facilitating the separation of the tapered fixed block 202 from the tapered sliding block 203 by the tapered slider 304 and its movement between the tapered fixed block 202 and the tapered sliding block 203. This locks the self-locking drawer 2 within the small storage compartment 106. The end of the tapered slider 304 has a chamfer for sliding against the tapered sliding block 203, allowing it to disengage from the position between the tapered fixed block 202 and the tapered sliding block 203. The locking and unlocking of the self-locking drawer 2 inside the small storage chamber 106 is achieved through the cooperation of the sliding column 201, the conical fixing block 202, the conical sliding block 203, the transverse slide groove 307, and the conical slider 304 of the positioning and identification module. When the operator pushes the self-locking drawer 2 into the small storage chamber 106, the sliding column 201, which is fixedly connected to the end face of the self-locking drawer 2, will drive the conical fixing block 202 and the outer conical sliding block 203, which will then enter the side of the small storage chamber 106. Within the transverse slide groove 307, during the pushing process, the conical fixing block 202 will first contact the conical slider 304 of the positioning and identification module. Since the size of the conical sliding block 203 is slightly larger than the size of the conical fixing block 202, the conical slider 304 will separate the conical fixing block 202 and the conical sliding block 203 and enter between them, thereby completing the locking of the self-locking drawer 2 inside the small storage chamber 106. If it is necessary to remove the hardware, the operator continues to push the self-locking drawer 2, and the conical slider 304... The tapered block 201 will move away from the position between the tapered fixing block 202 and the tapered sliding block 203, and push the tapered sliding block 203 towards the tapered fixing block 202, so that the tapered fixing block 202 and the tapered sliding block 203 are engaged. Then, the self-locking drawer 2 is pulled outward. The tapered slider 304 will pass through the surfaces of the tapered fixing block 202 and the tapered sliding block 203 in sequence. Finally, the slide column 201, the tapered fixing block 202, and the tapered sliding block 203 will disengage from the transverse slide groove 307, releasing the lock on the self-locking drawer 2.

[0027] Spring 302 provides the reset capability of tapered slider 304. Spring 302 is connected between pressure sensor bracket 301 and square slide plate 303. Pressure sensor bracket 301 detects the force on spring 302. Guide block 305 is fixedly installed on the outer periphery of square slide plate 303. Limit block 306 is installed at one end of vertical slide groove 3 near horizontal slide groove 307 to cooperate with guide block 305 and prevent tapered slider 304 from disengaging from the interior of vertical slide groove 3. The coordinated operation of positioning recognition modules enables precise locking and status detection of self-locking drawer 2. Two positioning recognition modules are symmetrically installed inside vertical slide groove 3 about horizontal slide groove 307. Vertical slide groove 3 is the positioning recognition module. The block provides a stable installation space; when the conical sliding block 203 enters the transverse slide groove 307, the conical slider 304, under the elastic force of the spring 302, slides against the conical sliding block 203 by means of the chamfer at the end, and gradually embeds itself between the conical fixing block 202 and the conical sliding block 203, thereby locking the position of the self-locking drawer 2 inside the small placement chamber 106; the guide block 305 on the outer periphery of the square slide plate 303 cooperates with the limiting block 306 at the end of the vertical slide groove 3 to prevent the conical slider 304 from disengaging from the vertical slide groove 3; the pressure sensor bracket 301 is connected between the spring 302 and the square slide plate 303 to detect the force on the spring 302 in real time and provide feedback on the locking status of the self-locking drawer 2.

[0028] The top of cabinet 1 is provided with two temporary placement slots 107. One of the temporary placement slots 107 has a separation mesh 4 installed on its top for separating hardware from impurities. Cross-shaped sliding grooves 401 are provided on both sides of the temporary placement slot 107. Cross-shaped sliding blocks 402 are laterally connected inside the two cross-shaped sliding grooves 401. A rotating column 403 is rotatably connected between the two cross-shaped sliding blocks 402. A flexible scraper 405 for cleaning impurities inside the temporary placement slot 107 is installed on the outer periphery of the rotating column 403. A rotating handle 404 for easy operation is installed at one end of the rotating column 403. The separation and cleaning of impurities in the top temporary placement slot 107 is achieved through the separation mesh 4, the cross-shaped sliding grooves 401, and the cross-shaped sliding grooves 402. The slider 402, rotating column 403, rotating handle 404, and flexible scraper 405 work together to achieve the following: the separation net 4 at the top of one of the temporary placement tanks 107 can separate the placed hardware from the impurities. The hardware remains above the separation net 4, while the impurities fall to the bottom of the temporary placement tank 107. When it is necessary to clean the impurities, the operator rotates the rotating handle 404, which drives the rotating column 403 to rotate. The cross sliders 402 at both ends of the rotating column 403 can slide laterally in the cross groove 401, thereby driving the flexible scraper 405 on the outer periphery of the rotating column 403 to move. The flexible scraper 405 fits against the inner wall of the temporary placement tank 107 and cleans the impurities in the tank to the designated position, completing the cleaning of the temporary placement area.

[0029] A vertical bracket 5 is installed on the side of the cabinet 1. A limit bracket 501 and a placement bracket 502 are respectively installed on the upper and lower outer periphery of the vertical bracket 5. Both the limit bracket 501 and the placement bracket 502 have multiple placement holes 503 for placing rod-shaped hardware. The placement of the rod-shaped hardware is accomplished by the cooperation of the vertical bracket 5, the limit bracket 501, the placement bracket 502, and the placement holes 503. The vertical bracket 5 installed on the side of the cabinet 1 provides mounting support for the limit bracket 501 and the placement bracket 502. 01 and the placement rack 502 are respectively installed on the upper and lower outer periphery of the vertical support 5. Multiple placement holes 503 on the surface of both can be used to insert rod-shaped hardware. The limiting rack 501 limits the top of the rod-shaped hardware, and the placement rack 502 supports its bottom to prevent the rod-shaped hardware from tipping over or being lost, thus realizing convenient access and orderly storage of the rod-shaped hardware. At the same time, the safety lock on the side of the valuables cabinet 105 can prevent unauthorized personnel from opening it, further ensuring the safety of the stored valuables.

[0030] The valuables cabinet 105 has a door and a safety lock installed on its side. The bottom of the cabinet 1 is equipped with multiple casters 101 for easy movement. The side of the cabinet 1 is equipped with a push handle 102. The overall movement and classified storage of the hardware storage cabinet are completed by the cabinet 1, the casters 101, the push handle 102 and various storage units working together. The operator can push the push handle 102 and use the multiple casters 101 at the bottom of the cabinet 1 to move the entire cabinet 1 flexibly to adapt to the location requirements of different usage scenarios. The multi-layer storage units inside the cabinet 1 realize the classified storage of various hardware parts. Among them, the medium-sized storage compartment 103 is used to store medium-sized hardware parts, the accessory drawer 104 is used to store small and scattered accessories, the valuables cabinet 105 realizes the safe storage of valuable hardware parts through the door and safety lock installed on the side, and the multiple small storage compartments 106 are used to classify and store small hardware parts of different sizes. The various storage units have clear division of labor to avoid the hardware parts being piled up in a mess.

[0031] The positioning and identification module is the core component of the hardware storage cabinet for achieving precise positioning and status monitoring of self-locking drawers. Its working principle is to complete locking, unlocking, and status feedback through the coordinated cooperation of various components. Specifically: the module is installed inside the vertical slide rail 3. The spring 302 connects the pressure sensor bracket 301 and the square slide plate 303, providing a restoring force for the conical slider 304. The guide block 305 on the outer periphery of the square slide plate 303 cooperates with the limiting block 306 at the end of the vertical slide rail 3 to prevent the conical slider 304 from leaving the track. When the self-locking drawer 2 is pushed into the small storage chamber 106, the conical fixing block 202 first contacts the conical slider 304. Because the conical sliding block 203 is slightly larger, the conical slider 304 separates from the two and embeds itself between them to complete the locking. The pressure sensor bracket 301 detects the force on the spring 302 in real time. When unlocking, pushing the drawer causes the conical slider 304 to disengage and push the two together, the spring 302 to reset, and the pressure sensor bracket 301 provides feedback on the unlocking status. This module offers significant advantages, including precise locking of self-locking drawers to prevent accidental slippage and falling hardware, real-time monitoring of the locking status to avoid the risk of unlocked drawers, a simple and reliable structure, easy maintenance, and the ability to use pressure changes to help determine if items are inside the drawer, improving hardware storage security and management efficiency. The preferred pressure sensor is a miniature piezoresistive pressure sensor (such as the FSR402), which is small, highly sensitive, and suitable for embedded installation, accurately detecting minute changes in spring force. Alternatively, a small strain gauge pressure sensor can be used, offering high stability and meeting the pressure detection needs of warehouse equipment. Existing technologies referenced include drawer self-locking technology and warehouse equipment pressure detection technology. It draws inspiration from the spring reset and limit design of self-locking storage devices, references the application of pressure sensors in warehouse racking for force monitoring, and incorporates the spring linkage design of a bidirectional self-resetting mechanism to optimize the module's reset reliability and positioning accuracy.

[0032] To ensure the long-term stable operation of the hardware storage cabinet, targeted measures should be taken in five core aspects: environment, maintenance, materials, component compatibility, and personnel operation, to avoid the adverse effects of various factors. Regarding the environment, to address environmental factors that can affect equipment operation, such as humidity, dust, and high temperatures, the storage cabinet should be placed in a dry and well-ventilated area. Prolonged exposure to humidity can cause corrosion of the cabinet body 1, casters 101, and internal components of the positioning and identification module. A moisture-proof pad can be added to the bottom of the cabinet body 1, and sealing strips can be installed at the openings of the vertical slide rail 3, horizontal slide rail 307, and temporary placement slot 107 to prevent dust from entering and causing jamming. At the same time, direct sunlight and high temperatures should be avoided to prevent aging of plastic components and loss of elasticity of spring 302, ensuring the stable function of all components. In terms of maintenance, a comprehensive inspection of the equipment is required regularly. Impurities in the temporary placement tank 107 should be cleaned weekly, and the separation net 4 and flexible scraper 405 should be wiped clean to prevent impurities from accumulating and affecting separation and cleaning functions. The positioning and identification module should be inspected monthly, checking the elasticity of spring 302 and the wear of the conical slider 304. Lubricating oil should be applied to the sliding column 201, conical fixing block 202, conical sliding block 203, and caster wheel 101 to reduce component wear. The sensitivity of the pressure sensor holder 301 should be calibrated quarterly, and the clearance between the guide block 305 and the limit block 306 should be checked. Aged and worn components should be replaced promptly to ensure accurate module locking and detection functions. Regarding materials, cold-rolled steel plates are preferred for the main structure, such as the cabinet 1 and vertical support 5, and are treated with anti-corrosion and anti-rust treatment to prevent rusting over long-term use. Wear-resistant alloy materials are used for easily worn components such as the conical slider 304 and conical fixing block 202 to extend service life. High-strength elastic materials are used for spring 302 to ensure stable reset performance and prevent locking failure due to material fatigue. Regarding component fit, regularly check the assembly accuracy of each component, adjust the fit clearance between the sliding column 201 and the conical sliding block 203 to ensure smooth sliding; check the chamfer accuracy of the conical slider 304 to ensure it can smoothly disengage between the conical fixing block 202 and the conical sliding block 203; confirm that the guide block 305 and the limit block 306 are tightly fitted to prevent the conical slider 304 from disengaging from the vertical slide groove 3; check the fixing of the universal wheel 101 to avoid loosening during movement. Regarding personnel operation, establish standardized operating procedures, strictly prohibit forceful pushing and pulling of the self-locking drawer 2 to avoid damage to components such as the sliding column 201 and the conical fixing block 202; when operating the rotating handle 404 to clean impurities, apply moderate force to prevent damage to the cross slider 402 and the rotating column 403; train operators to clarify the functions of each component and key operating points to avoid misoperation leading to problems such as failure of the positioning recognition module and incomplete impurity separation, ensuring the equipment operates according to specifications.

[0033] Working principle When in use, the operator can push the handle 102 to move the cabinet 1 flexibly using the casters 101 at the bottom of the cabinet 1. The cabinet 1 has multiple storage units with clear division of labor: medium-sized storage compartment 103 stores medium-sized hardware parts, accessory drawer 104 stores loose accessories, valuables cabinet 105 is secured by a door and safety lock, and multiple small storage compartments 106 are used to store small hardware parts. When the self-locking drawer 2 is pushed into the small storage compartment 106, the slide column 201 drives the conical fixing block 202 and the conical sliding block 203 into the horizontal slide groove 307. The conical fixing block 202 first contacts the conical slider 304 of the positioning identification module. Because the conical sliding block 203 is slightly larger, the conical slider 304 separates the two and embeds between them to complete the locking. When taking it out, continue to push the self-locking drawer 2, the conical slider 304 disengages and pushes the conical sliding block 203 to engage with the conical fixing block 202, and pulling out the self-locking drawer 2 will release the lock. In the positioning and identification module, spring 302 provides a restoring force, pressure sensor bracket 301 detects the force on spring 302, and guide block 305 and limit block 306 prevent conical slider 304 from disengaging from vertical slide groove 3. In the temporary placement slot 107 at the top of cabinet 1, separation mesh 4 separates hardware parts from impurities. Rotating the rotating handle 404 drives the rotating column 403 and flexible scraper 405, which, together with cross slide groove 401 and cross slider 402, can clean impurities. Limit bracket 501 and placement bracket 502 on vertical bracket 5 achieve orderly placement of rod-shaped hardware parts through placement hole 503.
