Description

Technical Field

[0001] This application relates to the field of electrical equipment maintenance technology, and in particular to a multifunctional electrical maintenance toolbox. Background Technology

[0002] With the rapid development of modern industry, electrical equipment is widely used in people's daily lives. As usage demands change, the number and complexity of electrical equipment are constantly increasing. Whether it is large-scale electrical equipment in industrial production or various electrical appliances in daily life, they all require regular maintenance and repair. This places higher demands on electrical maintenance tools, requiring tools that can adapt to the maintenance work of different types and complexities of electrical equipment.

[0003] However, electrical repairs require the use of various tools, and repair personnel often spend a lot of time searching for the right tools in their tool kits. This not only reduces repair efficiency but may also delay repairs in emergency situations, causing greater losses. At the same time, distraction while searching for tools may cause repair personnel to overlook some safety details, increasing safety hazards.

[0004] Based on this, researchers have designed various toolboxes. For example, patent CN219987604U discloses an electrical repair toolbox. This toolbox features several tool compartments inside the box and a limiting and pressing structure on the inner surface of the lid. Specifically, the limiting and pressing structure includes a hollow block, a sliding cover, a rubber pad, and an adjusting component. The sliding cover is movably fitted onto the outer surface of the hollow block, and the rubber pad is fixed to the outer end face of the sliding cover. The adjusting component includes a fixing plate and an adjusting spring. The fixing plate is fixed to the inner side of the sliding cover and connected to the end of the hollow block via the adjusting spring. When the lid is closed, the limiting and pressing structure can press and limit the tools within each compartment, ensuring the tools are stably placed within their respective compartments, preventing shaking or impact and avoiding disarray, wear, and damage during transport. However, this toolbox emphasizes tool stability during transport, relying on the pressing and limiting structure for tool fixation, making it suitable for small-scale tool transport. Furthermore, its complex structure may increase maintenance costs.

[0005] For example, patent CN214181464U discloses a cardiac defibrillator for cardiac surgery, including a convenient storage case for the defibrillator. A rotating pin is connected to one side of the storage case, and a convenient safety cover is connected to the other side of the rotating pin. A handle is installed in the middle of one side of the safety cover, and anti-collision rubber sleeves are attached to the four corners of the outer surface of the safety cover. This cardiac defibrillator for cardiac surgery, through the use of the convenient storage case and the convenient safety cover, allows for simple and convenient carrying of the defibrillator and discharge control circuit. The power cord storage groove and convenient Velcro device provide safe and reliable protection for the power cord. The anti-collision rubber sleeves prevent direct damage to the case from accidental collisions during movement, thus improving the convenience and safety of the device. However, this storage case emphasizes the protection of the case itself from collision damage, while neglecting the anti-collision features for the device inside the case. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a multifunctional electrical repair toolbox that enables the classified storage of tools, ensuring both neatness and safety against tool collisions. It also allows for quick retrieval and return of tools, resulting in high work efficiency.

[0007] To achieve the above objectives, this utility model provides a multifunctional electrical repair toolbox, comprising an upper toolbox and a lower toolbox hinged together. The lower toolbox has a liftable double-layer storage space for classifying and storing electrical repair tools, and the double-layer storage space is equipped with a double-layer buffer protection mechanism for buffering and protecting the electrical repair tools. The upper toolbox is equipped with a protective limit component. When the upper and lower toolboxes are closed, the double-layer buffer protection mechanism and the protective limit component provide double-layer buffer protection for the electrical repair tools and limit their displacement.

[0008] Furthermore, the lower toolbox includes a first storage rack, a second storage rack, a threaded rod, and a limiting rod. The limiting rod is fixedly installed on the side of the second storage rack facing the first storage rack. The threaded rod is rotatably connected to the second storage rack and is installed on the same side as the limiting rod. The first storage rack can move up and down relative to the second storage rack through the cooperation of the threaded rod and the limiting rod, forming a double-layer storage space with the second storage rack.

[0009] Furthermore, the lower toolbox also includes a drive ring, which is sleeved on the outer circumferential surface of the threaded rod and rotates synchronously with the threaded rod.

[0010] Furthermore, the first storage rack is threadedly connected to the threaded rod and slidably connected to the limiting rod, and a protective pad is installed on the side of the first storage rack facing the second storage rack.

[0011] Furthermore, both the first and second storage shelves are equipped with identification signs.

[0012] Furthermore, the protective limiting assembly includes a clamping mechanism, which includes a pressing frame, a telescopic rod, and a spring. The telescopic rod is mounted on the pressing frame, and the spring is sleeved on the outer circumferential surface of the telescopic rod and connected to the pressing frame. When the upper toolbox and the lower toolbox are closed, the electrical maintenance tools are clamped and limited by the clamping mechanism.

[0013] Furthermore, the protective limiting assembly also includes friction pads, which are mounted opposite to the telescopic rods on both sides of the extrusion frame.

[0014] Furthermore, the double-layer buffer protection mechanism includes a first anti-collision pad installed around the inner wall of the first storage rack, and the opening area formed by the first anti-collision pad matches the area of ​​the extrusion rack.

[0015] Furthermore, the double-layer buffer protection mechanism also includes a second anti-collision pad installed around the inner wall of the second storage rack.

[0016] Furthermore, the lower toolbox also includes an elastic restraint strap, which is mounted on the second anti-collision pad.

[0017] The beneficial technical effects of this utility model are as follows:

[0018] This utility model utilizes a double-layered storage space formed by a first and second storage rack to categorize and store electrical repair tools, improving the organization of storage. The liftable double-layered storage space facilitates tool retrieval and return, enhancing work efficiency. A clamping mechanism automatically clamps the tools when the toolbox is closed, and friction pads increase friction with the tools, effectively protecting them and preventing them from shaking. A double-layered buffer protection mechanism composed of a first and second anti-collision pad prevents tools inside the toolbox from colliding and damaging each other during movement, and elastic restraint straps further secure the tools, limiting their displacement.

The present invention is further illustrated below by specific examples; however, it should be noted that the specific process conditions and results described in the embodiments of this invention are for illustrative purposes only and should not be construed as limiting the scope of protection of this invention. All equivalent changes or modifications made in accordance with the spirit and essence of this invention should be covered within the scope of protection of this invention.

[0027] In the figures of this utility model embodiment, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper", "lower", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0028] likeFigure 1 As shown, this utility model provides a multifunctional electrical repair toolbox, including an upper toolbox 2 and a lower toolbox 1 hinged together. The lower toolbox 1 is provided with a liftable double-layer storage space for classifying and storing electrical repair tools. The double-layer storage space is provided with a double-layer buffer protection mechanism for buffering and protecting the electrical repair tools. The upper toolbox 2 is provided with a protective limiting component 4. When the upper toolbox 2 and the lower toolbox 1 are closed, the double-layer buffer protection mechanism and the protective limiting component 4 provide double-layer buffer protection for the electrical repair tools and limit the displacement of the electrical repair tools.

[0029] Furthermore, multiple hinges are drilled and fixed on one side of the lower toolbox 1 of this application, and are hinged to the upper toolbox 2 through the hinges. This application does not specifically limit the opening degree and number of the hinges, but sets them according to actual needs. For example, based on the weight of the electrical repair tools stored, the number of hinges and the installation position of the hinges are selected to have sufficient load-bearing capacity.

[0030] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the lower toolbox 1 of this application is equipped with a storage and sorting component 3. The storage and sorting component 3 includes a first storage rack 31, a second storage rack 37, a threaded rod 35, and a limiting rod 34. The limiting rod 34 is fixedly installed on the side of the second storage rack 37 facing the first storage rack 31. The threaded rod 35 is rotatably connected to the second storage rack 37 and is installed on the same side as the limiting rod 34. The first storage rack 31 can move up and down relative to the second storage rack 37 through the cooperation of the threaded rod 35 and the limiting rod 34, forming a double-layer storage space with the second storage rack 37. Specifically, the second storage rack 37 of this application is fixedly installed on the inner wall of the lower toolbox 1. The limiting rods 34 are fixedly installed at the four corners of the top of the second storage rack 37, and the threaded rod 35 is rotatably connected to the top of the second storage rack 37. The threaded rod 35 of this application is located between the two limiting rods 34. The threaded rod 35 is externally threaded to the first storage rack 31, and the first storage rack 31 is slidably connected to the limiting rod 34 through a sliding hole provided inside it. More specifically, the fixing and installation methods of this application include, but are not limited to, adhesive bonding, snap-fit ​​bonding, and screw connection.

[0031] Furthermore, such as Figure 3 As shown, the storage and sorting component 3 also includes a drive ring 36, which is sleeved on the outer circumferential surface of the threaded rod 35 and rotates synchronously with the threaded rod 35. Specifically, when the multi-functional electrical repair toolbox is opened and tools need to be taken out, the operator first rotates the drive ring 36. The drive ring 36 drives the threaded rod 35 to rotate, and through thread engagement, pushes the first storage rack 31 to slide up and down relative to the second storage rack 37, thereby forming a liftable double-layer storage space.

[0032] Furthermore, such as Figure 3 As shown, a protective pad 32 is installed on the side of the first storage rack 31 facing the second storage rack 37. The protective pad 32 serves to cushion and protect tools when they are placed on it, preventing them from colliding and being damaged. This application does not specifically limit the material of the protective pad 32; it can be selected according to actual needs, such as PVC foam, polyurethane foam, or rubber sponge.

[0033] Furthermore, such as Figure 3 As shown, both the first storage rack 31 and the second storage rack 37 are equipped with identification plates 33. The identification plates 33 of this application are used to mark the types of tools placed in different storage areas, facilitating quick tool retrieval.

[0034] Furthermore, such as Figure 4 As shown, the protective limiting component 4 includes a clamping mechanism, which comprises a pressing frame 42, a telescopic rod 44, and a spring 43. The telescopic rod 44 is mounted on the pressing frame 42, and the spring 43 is sleeved on the outer circumferential surface of the telescopic rod 44 and connected to the pressing frame 42. When the upper toolbox 2 and the lower toolbox 1 are closed, the electrical repair tools are clamped and limited by the clamping mechanism. Furthermore, the number of pressing frames 42 in this application matches the number of storage areas in the lower toolbox 1. One end of the telescopic rod 44 is fixedly installed inside the upper toolbox 2, and the other end is fixedly connected to the pressing frame 42. Preferably, telescopic rods 44 are installed at all four corners of the pressing frame 42. Specifically, the pressing frame 42 in this application adopts a frame structure, which can achieve a larger area of ​​pressing. When the upper toolbox 2 and lower toolbox 1 are closed, the downward pressure of the upper toolbox 2 is transmitted to the pressing frame 42 through the telescopic rod 44. At the same time, the spring 43 is compressed to generate a rebound force. The resultant force of these two forces causes the pressing frame 42 to contact the tool surface with appropriate pressure, forming an elastic buffering effect. Furthermore, the pressing frame 42 increases the friction between the tool and the storage area by continuously applying downward pressure, effectively preventing the tool from sliding due to vibration or tilting during the movement and handling of the toolbox. In addition, the telescopic rods 44 at the four corners ensure that the pressure of the pressing frame 42 is evenly distributed, preventing excessive local pressure from causing tool deformation.

[0035] Furthermore, such as Figure 4 As shown, the protective limiting component 4 also includes a friction pad 41, which is mounted opposite to the telescopic rod 44 on both sides of the extrusion frame 42. The friction pad 41 in this application increases the contact friction with the tool surface, preventing the tool from sliding or colliding when the toolbox moves or vibrates; furthermore, the soft interface of the friction pad 41 prevents direct contact between the tool and the metal parts of the extrusion frame 42, reducing scratches. Specifically, this application does not specifically limit the material of the friction pad 41; it can be selected according to actual needs, such as polyurethane, rubber, etc.

[0036] Furthermore, such asFigure 4 As shown, the double-layer buffer protection mechanism includes a first anti-collision pad 45 installed around the inner wall of the first storage rack 31, the opening area formed by the first anti-collision pad 45 matching the area of ​​the extrusion rack 42; the double-layer buffer protection mechanism also includes a second anti-collision pad 46 installed around the inner wall of the second storage rack 37. Preferably, the opening diameter formed by the first anti-collision pad 45 is slightly larger than the diameter of the extrusion rack 42 to allow for slight deformation buffering. Furthermore, the double-layer buffer protection mechanism provides all-round protection for the internal tools through the synergistic effect of the first anti-collision pad 45 and the second anti-collision pad 46. The double-layer buffer protection mechanism can provide static protection for tools when stored and can also optimize dynamic impact during toolbox movement and transportation. Specifically, this application does not specifically limit the material of the first anti-collision pad 45 and the second anti-collision pad 46, but selects them according to actual needs, such as polyurethane foam, rubber sponge, and silicone.

[0037] Furthermore, such as Figure 4 As shown, the lower toolbox 1 also includes an elastic restraint strap 47, which is mounted on the second anti-collision pad 46. The elastic restraint strap 47 is used to stably secure the tools inside the toolbox. This application does not limit the structure of the elastic restraint strap 47; it can be selected according to actual needs, such as a strip or mesh structure.

[0038] Furthermore, the working principle of the multifunctional electrical repair toolbox of this application is as follows:

[0039] When the toolbox is opened and tools need to be taken out, first rotate the drive ring 36 to rotate the threaded rod 35. Since the first storage rack 31 is slidably connected to the limit rod 34 through the sliding hole, the first storage rack 31 will move up and down along the limit rod 34 when the threaded rod 35 rotates, so that the toolbox can hold more repair tools. The first storage rack 31 and the second storage rack 37 are set here to classify and store repair tools. The protective pad 32 at the bottom of the first storage rack 31 can prevent repair tools from colliding and being damaged by the second storage rack 37. The label 33 is set to help users quickly identify the type of tools placed in the storage rack, thereby improving the efficiency of retrieval.

[0040] When the upper toolbox 2 and the lower toolbox 1 are closed, the compression frame 42, under the action of the spring 43 and the telescopic rod 44, compresses and fixes the tools placed in the first storage rack 31. The friction pad 41 at the top increases the friction to prevent the tools from shaking. The first anti-collision pad 45 and the second anti-collision pad 46 can reduce the impact force on the tools. The elastic restraint band 47 restrains the tools inside the second anti-collision pad 46 to prevent them from shifting. Furthermore, the opening diameter of the first anti-collision pad 45 is adapted to the compression frame 42, making the protective limiting effect in the first storage rack 31 more effective.

[0041] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
