DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is described in detail below in conjunction with the accompanying drawings.

[0038] A rotating support member, the rotating support member is arranged on the inner wall of the launch box body and corresponds to the cover plate one by one; a pin is arranged on the rotating support member, the rotating support member can rotate around the axis direction of the pin, and the axis direction of the pin is parallel to the first direction; the rotating support member has a first end and a second end; the rotating support member has two states;

[0039] An ejection support mechanism, the ejection support mechanism is arranged in the first space; the ejection support mechanism is provided with a bearing portion for bearing the object to be launched, and the ejection support mechanism also has an actuating end arranged along the launching direction of the bearing portion;

[0040] When the rotating support is in the first state and the cover is in the closed state, the lower surface of the cover is in contact with the first end, and the second end is separated from the actuating end;

[0041] When the rotating support is in the first state and the cover is in the open state, the stopper abuts against the first end;

[0042] When the rotating support is in the second state, the actuating end abuts against the second end, and the first end is disengaged from the stopper;

[0043] When the launchable member is launched, the actuating end can switch the rotating support member between the first state and the second state.

[0044] In a preferred embodiment, the inner wall of the launch box body 1 is cylindrical, and the outer wall is rectangular. The first space is used to place the launch object. The first space is provided with a first opening. A box cover is provided on one side of the first opening. The box cover has at least one cover plate 2, and one side of each cover plate 2 is rotatably connected to the launch box body 1, and the axial direction of the rotation axis is the first direction, that is, the cover plate 2 can be rotated around the rotation axis to open or close the first opening. A rotation fixing seat is fixed at the edge of the first opening, and the rotation fixing seat It has a first page and a second page, the first page is fixedly connected to the upper surface of the cover plate 2, the second page is fixedly connected to the edge of the upper surface of the launch box body 1, the first page and the second page are connected together through the rotating shaft, the rotating shaft is covered with a first torsion spring, the first torsion spring has a first foot and a second foot, the first foot abuts against the first page, and the second foot abuts against the second page; a stopper 3 is provided on the side wall of the cover plate 2 close to the first space and close to the rotating shaft, the stopper 3 is irregular in shape, and the shape of the stopper 3 is specifically referred to Figure 2 ;

[0045] The rotating support member 9 is arranged on the inner wall of the launch box body 1, and the number of the rotating support members 9 corresponds to the number of the cover plates 2, that is, each of the rotating support members 9 corresponds to one of the cover plates 2, and a pin shaft 7 is arranged on the rotating support member 9, and the rotating support member 9 can rotate around the axial direction of the pin shaft 7, and the axial direction of the pin shaft 7 is parallel to the first direction, that is, the axial direction of the pin shaft 7 is parallel to the axial direction of the cover plate 2 flipping, and the rotating support member 9 has a first end and a second end, and the rotating support member 9 has two states, namely a first state and a second state;

[0046] An ejection support mechanism is also provided in the first space, and a bearing portion 4 for bearing the object to be launched is provided on the ejection support mechanism, and the bearing portion 4 is circular, and the diameter of the bearing portion 4 is equal to the inner diameter of the inner wall of the launch box body 1, and the ejection support mechanism is also provided with an actuating end 5, and the actuating end 5 is fixed on the upper surface of the bearing portion 4 along the launching direction of the object to be launched;

[0047] When the rotating support member 9 is in the first state and the cover plate 2 is in the closed state, that is, the cover plate 2 closes the first space, and the first space is in a sealed state at this time. In the first state, the first end of the rotating support member 9 abuts against the lower surface of the cover plate 2, and the second end is separated from the actuating end 5;

[0048] When the rotating support member 9 is in the first state and the cover plate 2 is in the open state, the stopper 3 abuts against the first end;

[0049] When the rotating support member 9 is in the first state, the launch airflow of the launch member will open the cover plate 2 fixed on the launch box body 1, so that the cover plate 2 flips around the rotation axis in the direction away from the first space. During the flipping of the cover plate 2, the stopper 3 will make a circular motion around the rotation axis. During the circular motion of the stopper 3, one corner of the stopper 3 will touch the first end, and the first end will undergo a slight state change, such as Figure 2 As shown, when the stopper 3 does not touch the first end, the first end is close to the side wall of the launch box body 1. When the stopper 3 touches the first end, the first end will tilt to the right. When the stopper 3 passes the first end, the first end will instantly approach the direction of the side wall of the launch box body 1. At this time, the cover 2 is in a fully open state, but the impact force generated by the launch airflow of the object to be launched is very large. After opening, the cover 2 will move in the direction close to the first space, trying to close the first space, but a corner of the stopper 3 will abut against the upper surface of the first end, thereby preventing the cover 2 from closing the first space. At this time, the first space is completely in an open state, and the object to be launched will move upward under the thrust of the launch airflow, and the bearing portion 4 will also move upward with the object to be launched. During the upward movement, the actuating end 5 will contact the second end, causing the second end to gradually move toward the direction approaching the inner wall of the launch box body 1. Conversely, the first end will move toward the direction away from the inner wall of the launch box body 1, thereby forming an escape space between the first end and the inner wall of the launch box body 1, releasing the restriction of the first end on the block 3, so that the cover plate 2 and the block 3 can return to their original positions around the rotation axis, that is, at this time the rotating support 9 is in the second state, until the first end disengages from the block 3, that is, the first end is no longer in contact with the block 3, the cover plate 2 closes the first space, and the first space is in a sealed state at this time; that is, the actuating end 5 can switch the rotating support 9 between the first state and the second state.

[0050] During use, the launch component will generate airflow, and the generated airflow will push open the cover, and the block provided on the cover will make a circular motion around the rotating axis until the first end of the rotating support member abuts against the block. At this time, the cover is in a fully open state, and the launch component moves upward together with the bearing part. During the upward movement, the actuating end will contact the second end of the rotating support member, so that the second end gradually touches the inner wall of the launch box body. When the second end approaches the inner wall of the launch box body, the first end will move in the direction away from the inner wall of the launch box body, thereby forming an avoidance space, releasing the restriction on the block, so that the cover can fall and close the first space.

[0051] Furthermore, a surface of each actuating end 5 away from the axis of the launch box body 1 forms an inclined actuating surface 6 .

[0052] In a preferred embodiment, an actuating surface 6 is provided on the actuating end 5, and the actuating surface 6 is inclined. An angle opening upward is formed between the actuating surface 6 and the inner wall of the launch box body 1, and the angle is an acute angle.

[0053] Furthermore, the bearing portion 4 is provided with limiting openings 10 around it, and the inner wall of the launch box body 1 is provided with a guide rail 11 extending along a second direction, and the second direction is parallel to the launch direction of the launch object to be launched, and the bearing portion 4 is used in conjunction with the guide rail 11.

[0054] In a preferred embodiment, the bearing portion 4 is provided with limit openings 10 around the four sides, and the openings of the limit openings 10 face the inner wall of the launch box body 1. The number of the limit openings 10 can be multiple. In the present embodiment, the number of the limit openings 10 is three, and the three limit openings 10 are arranged equidistantly around the edge of the bearing portion 4. A guide rail 11 extending along a second direction is provided on the inner wall of the launch box body 1. The second direction is parallel to the launch direction of the component to be launched and is perpendicular to the first direction. The number of the guide rails 11 is equal to the number of the limit openings 10. In the present embodiment, the number of the guide rails 11 is also three, and the bearing portion 4 can move upward along the extension direction of the guide rail 11.

[0055] During use, when the launch object is ready to be launched, the launch airflow generated by the launch object will push the bearing part to move upward along the extension direction of the guide rail, thereby preventing the impact force of the launch airflow itself from causing the launch object to rotate on the inner wall of the launch box body. By setting a limit opening and a guide rail, the launch object can be launched in a fixed direction when launched.

[0056] Furthermore, the rotating support member 9 includes a mounting seat 12 arranged on the inner wall of the launch box body 1 along the second direction, a mounting groove 13 is opened in the mounting seat 12 along the second direction, a rotating rod 14 is provided in the mounting groove 13, the rotating rod 14 is hinged on the mounting seat 12 through the pin shaft 7, an elastic reset member 8 is provided between the rotating rod 14 and the mounting seat 12, and both ends of the rotating rod 14 pass through both ends of the mounting seat 12, a limiting member 15 is provided at the top end of the mounting seat 12, and the limiting member 15 has a fourth state and a fifth state, when the limiting member 15 is in the fourth state and the rotating support member 9 is in the first state, one end of the limiting member 15 abuts against the rotating rod 14, and when the limiting member 15 is in the fifth state and the rotating support member 9 is in the second state, the limiting member 15 extends into the mounting groove 13.

[0057] In a preferred embodiment, the rotating support seat includes a mounting seat 12, and the mounting seat 12 is fixed to the inner wall of the launch box body 1 along the second direction, for example, by welding or bolts. A mounting groove 13 is also provided in the mounting seat 12, and the mounting groove 13 extends along the second direction. Both ends of the mounting groove 13 are open, that is, the mounting groove 13 is a through groove along the vertical direction, and a rotating rod 14 is provided in the mounting groove 13, and the two ends of the rotating rod 14 extend outwards respectively. The rotating rod 14 is hinged on the mounting seat 12 through the pin shaft 7, and the pin shaft 7 extends along the first direction, that is, extends along the axis direction of the cover plate 2 flipping. The pin shaft 7 is sleeved with the elastic reset member 8, and the elastic reset member 8 is a second torsion spring. The second torsion spring has a third leg and a fourth leg, and the third leg abuts against the mounting groove 13, and the fourth leg abuts against the rotating rod 14. The pin shaft 7 and the elastic reset member 8 are both arranged at a relatively lower position of the mounting seat 12, such as Figure 5 As shown, a limiting member 15 is also provided at the top of the installation slot 13. The specific position of the limiting member 15 is as shown in FIG. Figure 5As shown, the limit member 15 extends along the first direction, and the limit member 15 has a fourth state and a fifth state. The fourth state means that the limit member 15 is always in the through hole opened on the mounting seat 12, and there is no position change. When the limit member 15 is in the fourth state and the rotating support member 9 is in the first state, one end of the limit member 15 abuts against the side wall of the rotating rod 14, and the first end abuts against the lower surface of the cover plate 2. At this time, the launch box body 1 is in a closed state; the fifth state means that the limit member 15 moves from the through hole of the mounting seat 12 along the first direction to the inside of the mounting groove 13, so that the first end of the rotating support member 9 is always maintained in the second state, that is, the avoidance space is formed between the first end and the inner wall of the launch box body 1, and the function of the limit member 15 in the fifth state is to maintain the formed avoidance space, so that the cover plate 2 can fall to close the launch box body 1; the limit member 15 can use but is not limited to glass, and the glass is cylindrical.

[0058] Furthermore, an elastic member is provided at one end of the limiting member 15 away from the rotating rod 14 , and the elastic member is retractable along the first direction.

[0059] In a preferred embodiment, the elastic member is provided at one end of the limiting member 15 away from the rotating rod 14, that is, the limiting member 15 and the elastic member are arranged in sequence along the first direction, and the elastic member is a spring; when the limiting member 15 is in the fourth state, the elastic member is in a state of storing force, and the end of the limiting member 15 away from the elastic member abuts against the rotating rod 14 in the rotating support member 9; and when the rotating support member 9 is in the second state, the rotating rod 14 releases the restriction on the elastic member, and the elastic member is in a state of releasing force. The elastic force of the elastic member itself causes one end of the limiting member 15 to extend into the mounting groove 13, thereby preventing the first end from returning to the first state.

[0060] Furthermore, a blocking block 17 is further provided on the inner wall of the launch box body 1 , and one end of the blocking block 17 can abut against the upper surface of the bearing portion 4 .

[0061] In a preferred embodiment, the blocking block 17 is rectangular in shape, and the blocking block 17 is arranged on the inner wall of the launch box body 1 and fits with the inner wall of the launch box body 1, and the blocking block 17 and the launch box body 1 are fixed by bolts; the lower surface of the blocking block 17 is a plane, and the lower surface of the blocking block 17 can abut against the upper surface of the bearing part 4.

[0062] During use, when the object to be launched is launched, the object to be launched will move upward with the bearing part. Since the object to be launched and the bearing part are connected by bolts, and a notch is provided in the middle of the bolt, when the upper surface of the bearing part collides and contacts with the lower surface of the blocking block, the bolt will break. After the bolt breaks, the object to be launched will fly out of the launch box body, while the bearing part will remain inside the launch box body under the action of the blocking block.

[0063] Furthermore, a buffer rod 18 is movably provided at one end of the blocking block 17 close to the bearing portion 4 . The buffer rod 18 extends along the second direction, and a buffer block 19 is provided at the other end of the buffer rod 18 .

[0064] In a preferred embodiment, a plurality of buffer holes are provided on one end of the blocking block 17 close to the bearing portion 4, the plurality of buffer holes all extend along the second direction, and each of the buffer holes penetrates the blocking block 17, the buffer rod 18 is movably provided in the buffer hole, that is, the buffer rod 18 can freely move up and down in the buffer hole, a buffer block 19 is further provided at one end of the buffer rod 18 away from the blocking block 17, the buffer block 19 is also fixedly connected to the inner wall of the launch box body 1, the buffer block 19 is in the shape of a rectangular parallelepiped, and the buffer block 19 and the buffer rod 18 are fixedly connected, for example, by welding.

[0065] During use, when the object to be launched is launched, the bearing part will move upward with the object to be launched, and the launching airflow has a strong impact force. When the upper surface of the bearing part abuts against the buffer block, part of the impact force will be reduced. If the buffer block is separated from the inner wall of the launch box body, the buffer block will enter the interior of the blocking block along with the buffer rod and contact the blocking block. At this time, the blocking block fixed on the inner wall of the launch box body will also block the upward movement of the bearing part, thereby separating the bearing part from the object to be launched.

[0066] Furthermore, a shielding member 20 is sleeved on the outer periphery of the buffer rod 18 .

[0067] In a preferred embodiment, a shielding member 20 is further provided on the periphery of the buffer rod 18. The shielding member 20 is sleeved on the periphery of the buffer rod 18 and fixedly connected to the buffer rod 18. The shielding member 20 is a circular iron ring, and the diameter of the iron ring is larger than the diameter of the buffer hole. A plurality of iron rings are evenly sleeved on the buffer rod 18, and the iron rings and the buffer rod 18 can be fixed together by welding.

[0068] During use, after the lowest buffer block is separated from the inner wall of the launch box body, the buffer block will move upward, and the buffer rod will also move upward. Because the diameter of the iron ring is larger than the diameter of the buffer hole, the iron ring will hit the lower surface of the blocking block during the upward movement of the buffer rod. If the impact force is too large, the iron ring at the top of the buffer rod will be broken. After the top iron ring is broken, the following iron rings will collide with the lower surface of the blocking block in turn until the bearing part is separated from the part to be launched. By arranging the buffer block, the buffer rod, the iron ring and the blocking block, the bearing part can be separated from the part to be launched.

[0069] Furthermore, a shielding block 21 is provided on the side wall of the cover plate 2 away from the first space.

[0070] In a preferred embodiment, a blocking block 21 is provided on the first page, and the blocking block 21 is a polyurethane pad. In the process of the cover plate 2 being flipped outward, in order to avoid the cover plate 2 being unable to subsequently close the launch box body 1 due to the flipping angle being too large, the blocking block 21 is provided on the first page, so that the flipping angle of the cover plate 2 from the closed state to the open state is maintained within 95 degrees to 100 degrees.

[0071] Furthermore, there are two cover plates 2, and a weakened portion is connected between two adjacent cover plates 2.

[0072] In a preferred embodiment, the number of the cover plates 2 is two, and a weakened portion is connected between two adjacent cover plates 2. Before the launch object is launched, the weakened portion is in a complete state. After the launch object is launched out of the launch box body 1, the weakened portion will break under the action of the launch airflow of the launch object, thereby dividing one cover plate 2 into two cover plates 2, and the two cover plates 2 are respectively arranged on opposite sides of the upper surface of the launch box body 1.

[0073] During use, when the launchable component is launched, the number of the cover plate is one. When the launchable component is launched, the cover plate impacts the weakened part open under the action of the launch airflow, and the number of the cover plates increases from one to two.

[0074] The launch box with automatic opening and closing function provided in the embodiment of the present application opens the cover under the action of the launch airflow of the component to be launched, and the component to be launched moves upward with the bearing part, and the actuating end on the bearing part touches the second end of the rotating support. In the process of the rotating support being converted from the first state to the second state, the upper surface of the bearing part contacts the buffer block. At the moment when the rotating support is switched to the second state, the limiting part on the rotating support extends into the installation groove under the action of elasticity to maintain the state of the rotating support. At this time, the component to be launched rushes out of the launch box body, the cover falls down, and the whole process is completed.
