Technical Field

[0001] This utility model relates to a support device for the door of an equipment case, specifically an upward-opening support device for the door of an equipment case, belonging to the technical field of equipment cases. Background Technology

[0002] Equipment cases are containers made of durable materials such as plastic and metal, primarily used for storing and protecting various equipment. Based on material, they can be categorized into plastic, metal, and wood types. Plastic equipment cases, in particular, are classified into three categories based on the synthetic materials used: ordinary polyethylene, ABS, and special engineering plastics. Shanghai Jirong Plastics Technology Co., Ltd.'s Defender series safety equipment cases meet EU standards and have obtained multiple patents. These products are widely used for equipment protection in various fields such as fire fighting, medical, communications, and military.

[0003] A search revealed a Chinese patent (CN210018146U) that discloses an equipment case where the positioning component can be detachably connected to a limiting component. When two or more equipment cases overlap, the upper case body rests on the lower case lid. In this case, the positioning component and the limiting component match each other, making the overlap of the two equipment cases more stable. To further stabilize the placement of a single equipment case, a limiting component matching the positioning component can be installed on the ground or other locations where the equipment case is placed. Stable placement of the equipment case prevents damage to the equipment caused by sliding or tipping during transportation.

[0004] While the above solutions can prevent equipment damage caused by sliding or tipping during transportation, the equipment boxes in the aforementioned patents have difficulty supporting the upward-opening door. The open door will be in an unstable state, and may suddenly close under slight external force. This will not only interrupt work but may also pinch the hands of operators who are taking out or putting in equipment, posing a safety risk. Therefore, we provide an upward-opening equipment box door support device to solve the above problems. Summary of the Invention

[0017] This utility model embodiment provides a support device for an upward-opening equipment box door. Example 1:

[0018] Please see Figure 4 and Figure 5 The equipment includes a housing 1, with a fixing block 5 fixedly connected to the other side of the housing 1. A second fixing shaft 6 is fixedly connected to the inner wall of the fixing block 5. The fixing block 5 is installed on the housing 1, and the second fixing shaft 6 is installed on the fixing block 5 to fix it. The rotating block 7 can be fixed through the second fixing shaft 6 to fix it. The rotating block 7 is rotatably connected to the end of the second fixing shaft 6 away from the fixing block 5. A limit rod 8 is rotatably connected to the inner side of the rotating block 7. When the rotating block 7 rotates, the limit rod 8 can be locked on the fixing buckle 9, thereby fixing the lid 206 and preventing the lid 206 from opening when the equipment box is moved, thus fixing it.

[0019] A storage box 3 is fixedly connected to the inside of the box 1, and a handling handle 4 is rotatably connected to one side of the box 1. The storage box 3 and the handling handle 4 are installed on the box 1. The storage box 3 can fix the equipment and prevent it from shaking during transportation. The staff can easily move the equipment box through the handling handle 4. Example 2:

[0020] Please see Figure 2 A support mechanism 2 is provided on the inner side of the box body 1. The support mechanism 2 includes a first fixed frame 201 fixedly connected to the inner side of the box body 1. A pneumatic support rod 202 is hinged to the inner side of the first fixed frame 201. A second fixed frame 203 is hinged to the telescopic end of the pneumatic support rod 202. A first movable rod 204 is fixedly connected to one side of the second fixed frame 203. When the box cover 206 is opened, the second fixed frame 203 can be pushed to unfold under the action of the pneumatic support rod 202. When the second fixed frame 203 rotates, it can push the first movable rod 204 to unfold, thereby supporting the opened box cover 206 and playing a supporting role.

[0021] The first movable rod 204 is rotatably connected to the middle of a first fixed shaft 208. The other end of the first fixed shaft 208 is rotatably connected to the inner wall of the third movable rod 207. The first fixed shaft 208 is mounted on the first movable rod 204. The third movable rod 207 can be mounted on the first movable rod 204 through the first fixed shaft 208, which can prevent the third movable rod 207 from tilting during rotation and play a fixing role. The lower end of the first movable rod 204 is rotatably connected to the inner side of the box 1. One side of the box 1 is hinged to one side of the box cover 206. The first movable rod 204 is mounted on the box 1, which allows the first movable rod 204 to rotate inside the box 1. The box cover 206 is mounted on the box 1, which can protect the equipment inside the box 1 and play a protective role. Example 3:

[0022] Please see Figure 1 and Figure 3The upper end of the first movable rod 204 is rotatably connected to the second movable rod 205. The end of the second movable rod 205 away from the first movable rod 204 is rotatably connected to the lid 206. A fixing buckle 9 is fixedly connected to one side of the lid 206. The fixing buckle 9 is engaged with the limiting rod 8. The fixing buckle 9 is installed on the lid 206. When the lid 206 is placed on the box body 1, it can be engaged with the fixing buckle 9 by the limiting rod 8, thereby fixing the lid 206. The second movable rod 205 is installed on the first movable rod 204. The second movable rod 205 can push the lid 206 for support. The lid 206 is installed on the second movable rod 205. The first movable rod 204 and the second movable rod 205 can support the lid 206, thus providing support.

[0023] A third movable rod 207 is rotatably connected to the inner side of the lid 206. A fourth movable rod 209 is rotatably connected to the end of the third movable rod 207 away from the lid 206. The lower end of the fourth movable rod 209 is rotatably connected to the inner side of the box body 1. When the lid 206 is opened, the third movable rod 207 and the fourth movable rod 209 can provide support to prevent the opened lid 206 from closing, thus providing support for the opened lid 206.

[0024] Working principle: When the user flips the lid 206 upwards, the lid 206 begins to rotate around its hinge point with the box body 1. This rotational motion is transmitted to the first movable rod 204 through the second movable rod 205, pushing the lower end of the first movable rod 204 to rotate around its fixed point on the box body 1. When the first movable rod 204 rotates, it drives the second fixed frame 203, which is fixedly connected to it, to rotate, thereby compressing or activating the pneumatic support rod 202. After the pneumatic support rod 202 is activated, the compressed gas inside it generates a linear thrust. The thrust acts on the second fixed frame 203 through its telescopic end, thereby providing auxiliary power for the continuous rotation of the first movable rod 204. The entire opening process is not driven solely by the pneumatic support rod 202, but is a linkage process triggered by the active opening action of the cover 206 and assisted and ultimately dominated by the pneumatic support rod 202. The third movable rod 207 and the fourth movable rod 209 are linked with the first movable rod 204 through the first fixed shaft 208. This multi-link mechanism converts the linear thrust of the pneumatic support rod 202 into... The smooth upward movement of the lid 206 along a preset trajectory effectively prevents the lid from shaking, shifting, or suddenly falling during opening. When the lid 206 is opened to its maximum angle, the pneumatic support rod 202 reaches its end point of travel or holds at its position. At this time, the internal pressure of the pneumatic support rod 202 enables it to resist the weight of the lid 206 and external forces, providing self-locking support. This reliably keeps the lid 206 in the open position, effectively preventing it from accidentally closing due to external forces or its own weight, ensuring operator safety and convenience. When loading or unloading equipment and closing the lid 206, a force sufficient to overcome the supporting force of the pneumatic support rod 202 is required to push the lid 206 down along a stable trajectory. After the lid 206 is fully closed, the limit rod 8 can be manually rotated to engage with the fixing buckle 9 on the lid 206. This independent mechanical locking device provides an additional safety guarantee for the closed lid 206, preventing the lid 206 from popping open even if the pneumatic support rod 202 fails unexpectedly, thus enhancing the safety and reliability during transportation and storage.
