Description

Technical Field

[0001] This utility model relates to the field of gripping technology for explosive materials, and in particular to a sealed gripping structure for explosive materials. Background Technology

[0002] With the widespread adoption of smartphones and the increasing penetration of mobile internet, the demand for portable charging has surged, making power banks a prime example of consumption upgrading and technological innovation. The rise of the sharing economy has further propelled the expansion of the power bank market, and the influx of capital has accelerated industry consolidation, leading to the emergence of dominant companies such as Jie Dian and Monster Charging. The global power bank market is projected to exceed 18 billion yuan by 2025, with China accounting for over 30% of global production capacity, making it the core of the industry chain.

[0003] Power banks are highly susceptible to exploding under the following abnormal conditions: First, high temperature, such as direct sunlight or proximity to heat sources, can cause the battery cells to overheat and explode. Second, short circuit, where a short circuit between the positive and negative terminals of the power bank battery can cause the battery cells to heat up rapidly and emit smoke, which may lead to an explosion in severe cases. Third, impact from heavy objects, where the internal battery cells may be damaged when the power bank is subjected to external impact or pressure, leading to short circuits and explosions. Fourth, quality issues, where some power banks have a risk of exploding due to problems with the battery cell assembly process, inadequate protection circuits, or insufficient aging tests.

[0004] Power bank explosions can seriously endanger the personal safety of travelers and cause property damage. They can also cause panic, especially in crowded places where evacuation is difficult, such as airplanes, subways, and high-speed trains. Recently, my country's civil aviation has banned passengers from bringing power banks without 3C certification on board.

[0005] When a power bank explodes, rescuers first use fire extinguishers. However, fire extinguishers can only extinguish the surface flames; the extinguishing agent cannot penetrate the battery cells inside. The heat from the initially exploding battery cells continues to conduct to nearby cells, causing the explosions to continue intermittently, with intervals ranging from several minutes to over ten minutes. By this time, the fire extinguisher has been used up, making fire extinguishers ineffective. Where possible, the exploding power bank or the bag containing it can be placed in an explosion-proof box. However, this method has two drawbacks: 1. There may not be an explosion-proof box available on-site; 2. Handling or using tongs to retrieve an exploding power bank is extremely dangerous. Therefore, equipment that can immediately retrieve an exploding power bank to a safer environment or place it in a retrieval device to allow it to release its energy is urgently needed by rescuers, but such equipment is currently unavailable.

[0035] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0036] Reference Figures 1-4 As shown in the figure, a sealed gripping structure for explosive materials is provided, including an operating handle 100, a wrapping cover 200, and a wrapping cover opening and closing control structure 300.

[0037] The operating handle 100 can maintain a sufficient safe distance between the operator and the exploding power bank. The operating handle 100 has a hollow structure and its length can be effectively extended and adjusted according to the actual situation. The length of the operating handle 100 is 1.2m-2m.

[0038] The enclosure 200 is designed to allow the operator to control its closure and effectively enclose the exploding power bank when it bursts into flames. The enclosure 200 is located on the front end of the operating handle 100.

[0039] The cover opening and closing control structure 300 is designed so that when the power bank explodes, the operator can control the cover to close and effectively enclose the exploding power bank in the closed cover. The cover opening and closing control structure 300 is set on the operating handle 100.

[0040] The enclosure 200 includes an inner cover 210 and an outer cover 220. The inner cover 210 has a semi-barrel-shaped structure, and the middle of the upper end of the inner cover 210 is connected to the front end of the operating handle 100 through a column hinge structure 340.

[0041] One outer cover 220 has a quarter-barrel-shaped structure. The outer cover 220 is symmetrically hinged to the inner cover on both sides through a connecting axis. The inner diameter of the outer cover 220 is slightly larger than the outer diameter of the inner cover 210.

[0042] A gear drive structure is provided on two connecting shafts on one side of the inner cover 210 to drive a pair of outer covers to open or close simultaneously. The gear drive structure makes it easier to control the opening or closing of the cover.

[0043] The gear drive structure includes a driving gear and a driven gear meshing with it. The driving gear is mounted on one of the connecting shafts located on one side of the inner cover, and the driven gear is mounted on another connecting shaft located on the other side of the inner cover.

[0044] On the other side of the inner cover 210, a torsion spring drive structure is provided on the two connecting shafts for providing driving force for closing an outer cover. The torsion spring drive structure includes a pair of torsion springs, which are respectively disposed on the two connecting shafts distributed on the other side of the inner cover.

[0045] A sealing element is provided at the gap between the outer cover 220 and the inner cover 210 to effectively improve the sealing performance between them. The sealing element is provided on the inner peripheral edge of the outer cover and the outer peripheral edge of the inner cover, which effectively improves the sealing performance between the outer cover and the inner cover.

[0046] A magnetic strip is provided on the edge of the outer cover 220, which can effectively improve the sealing effect when the cover is closed.

[0047] The cover opening and closing control structure 300 includes a slide 310, a positioning handle 320 and a steel wire rope 330. The slide 310 is rectangular in shape and is located at the tail of the operating handle 100 and extends along its length. A positioning groove 311 is provided at the tail of the slide 310.

[0048] The positioning handle 320 is slidably disposed in the slide groove 310. After the positioning handle 320 slides along the slide groove 310 to its tail, it can be positioned through the positioning groove 311. The wire rope 330 is used to pull the cover to open. The wire rope 330 is disposed inside the operating handle 100. The tail end of the wire rope 330 is disposed on the positioning handle 320. The front end of the wire rope 330 passes through the column hinge structure and is connected to the connecting lug 221 disposed in the middle of one of the outer covers 220.

[0049] The column hinge structure 340 includes a column 341 and a fixed foot 342. The column 341 is located at the middle of the upper end of the inner cover 210. The fixed foot 342 has a U-shaped cross-section. The base of the fixed foot 342 is fixedly installed on the front end of the operating handle 100. The protruding foot of the fixed foot 342 is hinged to the column 341 by a pin.

[0050] The inner circumferential surfaces of the outer cover 220 and the inner cover 210 are coated with fire extinguishing material to extinguish the fire inside the power bank. The fire extinguishing material can fully extinguish the fire inside the power bank sealed between the outer cover 220 and the inner cover 210.

[0051] The inner cover can be a flat semi-cylindrical structure, a semi-elliptical structure, or a hemispherical structure, etc. The specific shape of the inner cover can be selected according to the actual situation, which further improves the practical performance of the sealing gripping structure.

[0052] A positioning pin is provided on the upper part of the column 341 to limit the selection angle of the operating handle. The fixed foot 342 rotates around the pin until it reaches the positioning pin. The positioning pin can effectively control the rotation angle of the operating handle and can control the rotation angle of the operating handle between -30° and 60°, which further improves the practical performance of the sealed gripping structure.

[0053] In use, use the operating handle to place the cover over the power bank or the bag containing the power bank, completely covering it. Since the column 341 and the fixing foot 342 are only connected by a pin, the outer cover will rotate freely at the front end of the operating handle. Rotate the positioning handle to the slide groove, and the outer cover will rotate downward under the torque of the torsion spring, driving the steel wire rope and the positioning handle to move along the operating handle towards the cover. When one pair of outer covers closes, a sealed space is formed, grabbing the exploding power bank between the inner and outer covers; then move the cover to a safe position, such as inside an explosion-proof box.

[0054] If there is no explosion-proof box on site, wait for the power bank to release its energy before opening the cover and removing the power bank or bag that is now in a safe state after the explosion. If there is an explosion-proof box on site, place the cover on top of the box, open the cover, and place the power bank or bag inside. The cover opening procedure is as follows: Pull the positioning handle towards the rear of the operating handle. When it reaches the positioning slot, rotate the positioning handle to engage with the positioning slot. During this process, the object covered will rotate upwards and return to the open state.

[0055] In summary, this utility model has a reasonable overall design, simple structure, and convenient operation. By wrapping the power bank, it can quickly capture the exploding power bank and place it in a relatively safe environment to allow it to release its energy, thus avoiding affecting the personal safety of travelers and causing property damage. It also avoids causing panic among the crowd, thereby greatly facilitating the removal of power banks that have exploded in abnormal situations.
