Description

Technical Field

[0001] The invention relates to the technical field of vibration isolation equipment, and in particular to a vertical vibration isolation storage box and a use method thereof. Background Art

[0002] At present, in the field of aerospace, the equipment installed on land-based launchers, the equipment of high-speed surface ships, and the field of motion test laboratories usually need to withstand vertical vibrations that are much greater than lateral vibrations, and the acceleration and amplitude scale in the vertical direction are orders of magnitude different from the vibrations in other directions. If a vibration reduction structure is not set up, environmentally sensitive electronic components (such as chips, memory cards, memory sticks, etc.) cannot be stored in such an environment without damage.

[0003] In response to this situation, a relatively long multi-stage spring isolator or airbag isolator structure is usually used to provide a storage environment with a vibration reduction function for chip components. However, these methods have disadvantages: spring isolators or airbag isolators can usually only isolate acceleration but cannot isolate the motion amplitude, so the movement distance of the isolation object cannot be weakened. In addition, whether it is a spring or airbag isolator, its working principle relies on the absorption of impact force by elastic deformation, but the deformation will still be released in the end. Therefore, it can only prolong the release time of the impact force and achieve a certain degree of weakening. It is difficult to weaken the vibration acceleration to a very small indicator. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects and problems of poor vibration reduction effect of vibration isolation equipment in the prior art, and to provide a vertical vibration isolation storage box with good vibration isolation effect and a method of using the same.

[0007] The bottom assembly includes a bottom plate, a base, and a fixing clip. The base is connected to the upper side of the bottom plate. The tail of the box cover is hinged to the tail of the bottom plate through the base. The fixing clip is connected to the upper side of the bottom plate and is located inside the box cover. The sensitive electronic component is installed on the bottom plate through the fixing clip. The tail and head of the bottom plate are slidably connected to the first guide rod and the second guide rod respectively.

[0008] The storage box also includes a return spring and a rotating shaft, wherein the rotating shaft is connected to the base, and the box cover includes a connecting portion and a pressing portion, wherein the head of the connecting portion abuts against the head of the bottom plate, and the tail is rotatably connected to the bottom plate via the rotating shaft, the right side of the pressing portion is connected to the tail of the connecting portion, and the left side is arranged tilted upward, one end of the return spring is connected to the connecting portion, and the other end is connected to the bottom plate, and the structural cross-section enclosed by the connecting portion and the bottom plate is wing-shaped.

[0009] A first guide hole is provided at the top corner of the rear portion of the bottom plate, and a second guide hole is provided at the top corner of the head portion. A mounting hole corresponding to the second guide hole is provided at the top corner of the head portion of the connecting portion. The lower end of the first guide rod passes through the first guide hole and is connected to the bottom of the box body. The lower end of the second guide rod passes through the mounting hole and the second guide hole in sequence and is connected to the bottom of the box body.

[0010] The upper end surface of the bottom plate is evenly provided with a plurality of grooves, and a counterweight block is arranged in each of the plurality of grooves.

[0011] The groove and the counterweight block are both circular in shape, the depth of the groove is smaller than the height of the counterweight block, and the inner diameter of the groove is larger than the outer diameter of the counterweight block.

[0012] The upper and lower ends of the first guide rod and the second guide rod are both sleeved with a limit spring, and one end of the limit spring is connected to the box body.

[0015] A method for using a vertical vibration isolation storage box comprises the following steps:

[0016] Step 1: First press the tail of the box cover to open the box cover, then place the sensitive electronic components to be stored on the bottom assembly and fix them, then loosen the tail of the box cover so that the box cover covers the bottom assembly, and the storage box is now completely closed;

[0017] Step 2: First, install the storage box on the first guide rod and the second guide rod to keep the storage box in a horizontal state, then hold the bottom of the storage box by hand to make it located in the middle of the first guide rod and the second guide rod, then turn on the fan and adjust the wind speed of the fan.

The lid of the storage box is arranged to be streamlined so that the flow rate at the bottom of the bottom component is less than the flow rate at the top of the lid. Since the greater the flow rate, the smaller the pressure, the pressure at the bottom of the storage box is greater than the pressure at the top, generating lift. When the lift is exactly equal to the gravity of the storage box, the storage box is suspended in the box, and sensitive electronic components are stored in the storage box. When the box is subjected to vertical impact or movement, since the wind velocity is uniform and stable, the lift of the storage box is still balanced with the gravity, and its absolute position relative to the ground remains unchanged. Therefore, the present invention has a simple structure, strong vibration isolation capability, and good vibration isolation effect.

[0021] 2. In the vertical vibration isolation storage box and the use method thereof of the present invention, by setting a counterweight block, the weight of the entire storage box can be conveniently adjusted, and the use is convenient; the height of the groove is smaller than the height of the counterweight block, which facilitates the placement and removal of the counterweight block;

[0022] By arranging the limit spring, the storage box can be protected if it falls from the suspended state or rises quickly when the equipment fails. Therefore, the invention has high reliability and is easy to use.

[0023] 3. In the vertical vibration isolation storage box and the use method thereof of the present invention, a uniform wind field is achieved in the box by setting a damping net partition and a honeycomb spoiler partition, and air is easily circulated by setting the vent holes in a honeycomb structure. Therefore, the present invention has a stable structure and high reliability. BRIEF DESCRIPTION OF THE DRAWINGS
