Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figure 1 - Figure 7 As shown, a product design model storage device includes a box 1, a pair of top covers 2, a placement plate 3, and several casters 4. The top covers 2 on both sides are hinged to the top of the box 1. The placement plate 3 is slidably connected to the inner wall of the box 1. The casters 4 are fixedly installed at the four corners of the bottom of the box 1. A lifting support mechanism is provided at the bottom of the box 1. A dispensing output mechanism is provided inside the box 1. Support switching mechanisms are provided on both sides of the outer wall of the box 1. The lifting support mechanism includes a horizontal plate 51, which is fixedly installed inside the housing 1. An electric push rod 52 is fixedly installed at the bottom of the horizontal plate 51. A sliding seat 53 is fixedly connected to the drive end of the electric push rod 52. The top of the sliding seat 53 is slidably connected to the bottom of the horizontal plate 51. The dissipation mechanism includes a fan 67, which is fixedly installed at the center of the inner wall of the placement plate 3; The support switching mechanism includes a pair of electric telescopic rods 71, with the two electric telescopic rods 71 ​​fixedly installed on both sides of the outer wall of the housing 1.

[0022] It should be noted that in the initial state, the placement plate 3 is located inside the lower part of the box 1, the top cover 2 is closed, the casters 4 support the box 1 for easy movement, the lifting support mechanism can drive the placement plate 3 to slide up and down to realize convenient loading and unloading of the model, the dispensing mechanism can release the protective medium at the same time to protect the model from moisture and oxidation, and the support switching mechanism can switch to a stable support state after movement to prevent the box 1 from shaking.

[0023] The lifting support mechanism also includes a pair of inclined plates 54, with rollers 510 fixedly connected to the lower center of the two inclined plates 54, and the outer wall of the rollers 510 fixedly connected to the sliding seat 53.

[0024] It should be noted that when the electric push rod 52 is started, its drive end will push the sliding seat 53 to slide horizontally along the bottom of the horizontal plate 51. Since the sliding seat 53 is fixedly connected to the roller 510 below the inclined plate 54, the horizontal movement of the sliding seat 53 will drive the roller 510 to move synchronously, thereby driving the inclined plate 54 to deflect at an angle with the bottom roller 510 as the fulcrum, providing a power transmission basis for the subsequent lifting and lowering of the placement plate 3.

[0025] The bottom of the inner wall of the box 1 and the bottom of the placement plate 3 are both fixedly connected to the perforated plate 58. The two ends of the roller 510 are slidably connected to the middle of the lower perforated plate 58. The middle of the left side of both perforated plates 58 are rotatably connected to the rotating shaft 57.

[0026] It should be noted that the perforated plate 58 provides a sliding track for the roller 510. The lower perforated plate 58 is fixed to the bottom of the inner wall of the housing 1, and the upper perforated plate 58 is fixed to the bottom of the placement plate 3. The two ends of the roller 510 are embedded in the groove of the perforated plate 58 to ensure that the roller 510 will not deviate from the track when the sliding seat 53 drives the roller 510 to move. At the same time, the rotating shaft 57 on the left side of the perforated plate 58 provides a rotation fulcrum for the second inclined plate 55, so that the second inclined plate 55 can be adjusted in conjunction with the deflection of the first inclined plate 54.

[0027] Both sides of the rotating shaft 57 are provided with a second inclined plate 55 in the middle. The second inclined plate 55 is connected to the first inclined plate 54 through a connecting shaft 56. Another roller 510 is provided on the top of the second inclined plate 55. The top of the first inclined plate 54 is connected to the upper side strip hole plate 58 through another rotating shaft 57.

[0028] It should be noted that the inclined plate 1 54 and the inclined plate 2 55 are hinged together by the connecting shaft 56 to form a scissor-type support structure. When the inclined plate 1 54 is deflected by the roller 510, it will pull the inclined plate 2 55 to rotate around the rotating shaft 57 through the connecting shaft 56. The roller 510 at the top of the inclined plate 2 55 is embedded in the groove of the upper side strip hole plate 58. With the opening and closing of the scissor-type structure, the top roller 510 will slide along the upper side strip hole plate 58, thereby pushing the placement plate 3 to rise vertically along the inner wall of the box 1, realizing the lifting and placement of the model. Conversely, when the electric push rod 52 retracts, the placement plate 3 will descend smoothly and return to its original position.

[0029] Two-way screws 59 are fixedly connected to the opposite ends of the two connecting shafts 56. Vertical grooves 511 are opened on all four sides of the inner wall of the housing 1. Uprights 512 are fixedly connected to the inner walls of the vertical grooves 511 on both sides.

[0030] It should be noted that the opposite end of the connecting shaft 56 is fixed with a bidirectional screw 59. When the inclined plate 1 54 and the inclined plate 2 55 are linked, the connecting shaft 56 will drive the bidirectional screw 59 to rotate synchronously, providing power transmission for the distributing mechanism. At the same time, the vertical groove 511 on the inner wall of the box 1 provides installation space for the upright 512. The upright 512 is vertically fixed in the vertical groove 511, and the soft pad 514 on its outer wall is in contact with the side of the placement plate 3. When the placement plate 3 is raised or lowered, the soft pad 514 will slide along the upright 512. With the elasticity of the connecting spring 513, it plays a guiding and buffering role in the raising and lowering of the placement plate 3, avoiding direct friction between the placement plate 3 and the inner wall of the box 1.

[0031] A soft pad 514 is slidably connected to the outer wall of the upright 512. A connecting spring 513 is sleeved on the outer wall of the upright 512. The two ends of the connecting spring 513 are fixedly connected to the middle of the two ends of the soft pad 514. A spring rod 515 is fixedly connected to the top of the horizontal plate 51.

[0032] It should be noted that the connecting spring 513 is sleeved on the outer wall of the upright 512, and its two ends are fixed to the upper and lower ends of the soft pad 514 respectively. When the placement plate 3 rises or falls, the soft pad 514 will squeeze or stretch the connecting spring 513, using the elastic potential energy of the spring to counteract the impact force of the placement plate 3, ensuring that the model is placed stably. The spring rod 515 at the top of the horizontal plate 51 extends vertically upward, and its top end is connected to the storage cylinder 65. The spring rod 515 can elastically extend and retract with the rise and fall of the placement plate 3, avoiding hard collision between the storage cylinder 65 and the placement plate 3, and providing stable support for the storage cylinder 65.

[0033] In embodiment two, the dispensing mechanism also includes a pair of threaded blocks 61. The two threaded blocks 61 are threadedly connected to the outer wall of the bidirectional screw 59. A cover plate 62 is fixedly connected to the middle of the two threaded blocks 61. A storage cylinder 65 is fixedly connected to the top of the spring rod 515. The inside of the storage cylinder 65 is filled with anti-oxidation material to protect the quality of the model products in the box 1. A transverse hole 63 is opened in the middle of the storage cylinder 65. The outer wall of the threaded block 61 is slidably connected to the inner wall of the transverse hole 63.

[0034] It should be noted that when the bidirectional screw 59 rotates, the threaded block 61 on its outer wall will slide relative to or towards each other along the bidirectional screw 59 due to the thread transmission characteristics. The threaded block 61 passes through the transverse hole 63 of the storage cylinder 65, and the transverse hole 63 provides sliding guidance for the threaded block 61 to ensure that the threaded block 61 does not deviate when it moves. The threaded block 61 is fixedly connected to the cover plate 62. Therefore, the sliding of the threaded block 61 will drive the cover plate 62 to move synchronously, thereby realizing the opening and closing control of the venting hole 66 at the top of the storage cylinder 65. Antioxidant or desiccant is pre-loaded inside the storage cylinder 65 to provide a medium source for model protection.

[0035] Sealing films 64 are provided on the opposite sides of the two side cover plates 62. The middle sealing film 64 is fixedly connected to the two side cover plates 62. The two ends of the side sealing film 64 are fixedly connected to the cover plate 62 and the storage cylinder 65 respectively. Several emitting holes 66 are opened on both sides of the top of the storage cylinder 65. The top of the two side cover plates 62 is attached to the bottom of the two side emitting holes 66 respectively.

[0036] It should be noted that the sealing films 64 on both sides of the cover plate 62 serve a sealing function. The middle sealing film 64 connects the two cover plates 62, and the side sealing films 64 connect the cover plate 62 and the storage cylinder 65, ensuring that the inside of the storage cylinder 65 is sealed when the cover plate 62 is closed, thus preventing premature leakage of the protective medium. When the threaded block 61 drives the cover plate 62 to move towards each other, the cover plate 62 will detach from the bottom of the emitting hole 66, and the emitting hole 66 will open. The protective medium in the storage cylinder 65 can diffuse into the inside of the box 1 through the emitting hole 66. The fan 67 in the center of the inner wall of the placement plate 3 will start, accelerating the air circulation in the box 1, so that the protective medium can evenly cover the surface of the model, achieving moisture-proof and anti-oxidation protection. When the cover plate 62 moves relative to each other, the emitting hole 66 will close, stopping the output of the protective medium.

[0037] The support switching mechanism also includes two pairs of adjustment plates 72. The two adjustment plates 72 are respectively hinged to the bottom of the drive end of the electric telescopic rods 71 ​​on both sides. The outer walls of the housing 1 are fixedly connected to the horizontal seats 74 on both sides. The middle of the horizontal seats 74 on both sides is provided with inclined grooves 75. The inclined grooves 75 on both sides are opened from the inside to the outside from high to low, and the inner walls are slidably connected with sliders 73.

[0038] It should be noted that the support switching mechanism is used to switch between the moving and fixed states of the box 1. In the initial moving state, the electric telescopic rod 71 is in the retracted state, the adjusting plate 72 is in the tilted and retracted state, the counterweight plate 76 is away from the ground, and the caster wheel 4 undertakes the support and movement functions. When the box 1 moves to the target position, the electric telescopic rod 71 starts and extends, and its driving end pushes the adjusting plate 72 to deflect downward. The end of the adjusting plate 72 away from the electric telescopic rod 71 drives the slider 73 to slide along the inclined groove 75 of the cross seat 74 (the inclined groove 75 is designed from high to low from the inside to the outside), so that the slider 73 moves to the outside of the box 1 and descends synchronously.

[0039] The ends of the two adjustment plates 72 away from the electric telescopic rod 71 are respectively hinged to the top of the two sliders 73, and the bottom of the two sliders 73 are fixedly connected to the counterweight plate 76.

[0040] It should be noted that as the slider 73 moves, the counterweight plate 76 at the bottom gradually contacts the ground. Due to the inclined angle design of the sloping groove 75, the counterweight plate 76 will generate downward pressure when it contacts the ground. Combined with the weight of the counterweight plate 76 itself, it achieves stable support for the box 1. At this time, the caster wheel 4 is off the ground or only provides auxiliary support to prevent the box 1 from sliding when picking up or putting down the model. When it needs to be moved again, the electric telescopic rod 71 retracts, pulls the adjusting plate 72 to deflect upward, the slider 73 slides inward along the sloping groove 75, the counterweight plate 76 is lifted off the ground, the caster wheel 4 resumes its support function, and the box 1 can be moved again.

[0041] It should be noted that the specific installation methods, circuit connection methods, and control methods of the electric push rod 52, fan 67, and electric telescopic rod 71 used in this invention are all conventional designs, and will not be described in detail in this invention.

[0042] Working principle: The power source for the lifting action is the electric push rod 52 fixed at the bottom of the horizontal plate 51. After the electric push rod 52 is started, its driving end pushes the sliding seat 53 to slide horizontally along the bottom of the horizontal plate 51. The sliding seat 53 is fixedly connected to the roller 510 in the middle of the lower part of the inclined plate 1 54. The horizontal movement of the sliding seat 53 drives the roller 510 to slide along the groove of the lower perforated plate 58, thereby driving the inclined plate 1 54 to deflect with the bottom roller 510 as the fulcrum. The inclined plate 1 54 is hinged to the inclined plate 2 55 through the connecting shaft 56 to form a scissor-type support structure. The deflection of the inclined plate 1 54 pulls the inclined plate 2 55 to rotate synchronously around the rotating shaft 57 on the perforated plate 58 through the connecting shaft 56. The roller 510 at the top of the inclined plate 2 55 is embedded in the groove of the upper perforated plate 58. With the opening and closing of the scissor-type structure, the top roller 510 slides along the upper perforated plate 58, and finally pushes the placement plate 3 fixed to the upper perforated plate 58 to rise and fall vertically along the inner wall of the box 1. Uprights 512 are fixed in the vertical grooves 511 on the four sides of the inner wall of the box 1. The soft pads 514 slidably connected to the outer wall of the uprights 512 are in contact with the side of the placement plate 3, providing guidance for the lifting and lowering of the placement plate 3 and preventing deviation. The connecting springs 513 sleeved on the uprights 512 are fixed at both ends to the soft pads 514, which can buffer the impact force during the lifting and lowering of the placement plate 3, and at the same time prevent the placement plate 3 from directly rubbing against the inner wall of the box 1. The spring rod 515 at the top of the horizontal plate 51 provides elastic support for the subsequent storage cylinder 65, indirectly assisting the stability of the lifting and lowering of the placement plate 3. When the electric push rod 52 retracts, the sliding seat 53 slides in the opposite direction, causing the scissor-type structure to close, the placement plate 3 descends smoothly and resets, and the model is stored inside the box 1. In the lifting support mechanism, a bidirectional screw 59 is fixed at the opposite end of the connecting shaft 56. When the first inclined plate 54 and the second inclined plate 55 are linked through the connecting shaft 56, the connecting shaft 56 drives the bidirectional screw 59 to rotate synchronously, so as to achieve power synchronization with the lifting action. The outer wall of the bidirectional screw 59 is threaded with a threaded block 61. The threaded block 61 passes through the transverse hole 63 in the middle of the storage cylinder 65 and is fixedly connected to the cover plate 62. When the bidirectional screw 59 rotates, the threaded blocks 61 on both sides slide relative to each other or towards each other along the screw, thereby driving the cover plate 62 to move horizontally at the bottom of the storage cylinder 65. In the initial state, the cover plate 62 is attached to the bottom of the venting hole 66 at the top of the storage cylinder 65, sealing the venting hole 66. When the placement plate 3 descends to store the model, the bidirectional screw 59 rotates and drives the threaded blocks 61 to slide relative to each other. The cover plate 62 separates synchronously, and the venting hole 66 opens. Conversely, when the placement plate 3 rises, the cover plate 62 slides towards each other to close the venting hole 66. The sealing films 64 on both sides of the cover plate 62 are fixed to the cover plate 62 and the storage cylinder 65 respectively, ensuring that the inside of the storage cylinder 65 is sealed when the cover plate 62 is closed, preventing the protective medium from leaking prematurely. After the vent 66 is opened, the protective medium in the storage cylinder 65 is released into the box 1 through the vent 66. At the same time, the fan 67 in the center of the inner wall of the placement plate 3 is started to accelerate the air circulation in the box 1, so that the protective medium is evenly diffused to the surface of the model, achieving all-round protection.
