[0002] With the increasing demand for vertical launch of space rockets at sea and on land, and the continuous increase in launch density, higher requirements are placed on the functionality of rocket launch boxes. Existing rocket launch boxes in the current technology all use fragile covers, which are opened in a destructive way. However, this method of opening means that the launch box cover cannot be reused after it is opened, resulting in a waste of materials. Summary of the Invention

[0003] The purpose of this application is to address the above problems by providing a vertical launch box for rockets, comprising:

[0004] The launch box body has a first space for accommodating the simulated rocket body, and the first space has a first opening.

[0006] A launch unit is slidably connected to the inner wall of the launch box body. The launch unit includes a connecting structure and a simulated rocket body disposed on the connecting structure. The connecting structure has a first state and a second state. When it is in the first state, the connecting structure is fixedly connected to the simulated rocket body. When it is in the second state, one end of the connecting structure abuts against the snap-fit ​​plate, the simulated rocket body is slidably connected to the connecting structure, and the simulated rocket body can be separated from the connecting structure.

[0007] According to the technical solution provided in the embodiments of this application, the connection structure includes a connector, the connector having a first sliding groove extending along the launch direction of the simulated rocket body, a first mounting hole having a first sliding block having a first sliding block having a second mounting hole having a first sliding groove being slidably connected to the first sliding block, the first mounting hole being fixedly connected to the second mounting hole by a shear screw having the shear screw being able to break after being subjected to external force, and the connection structure switching from the first state to the second state.

[0008] According to the technical solution provided in the embodiments of this application, the side of the connector away from the first slide groove is provided with a second slider extending along the launch direction, and the inner sidewall of the launch box body is provided with a second slide groove extending along the launch direction, and the second slider is slidably connected to the second slide groove.

[0009] According to the technical solution provided in the embodiments of this application, two limiting members are provided inside the box cover on the side relatively close to the hinge axis, arranged along the first direction. The two limiting members and the hinge axis are arranged along the second direction, and the limiting ends of the two limiting members are arranged close to each other. The second direction is perpendicular to the first direction. A receiving groove for accommodating the limiting members is provided on the side of the connector corresponding to the limiting members, extending along the firing direction. The receiving groove has an abutting part at the end relatively close to the box cover. When the connector moves in the opposite direction to the firing direction under the action of the snap plate and its own weight, the abutting part abuts against the limiting members, so that the box cover closes the first opening.

[0010] According to the technical solution provided in the embodiments of this application, the limiting member includes a limiting plate extending in the opposite direction to the launching direction, a limiting shaft is provided on one side of the limiting plate that is close to each other, the limiting shaft extends in the first direction, and the limiting shaft has the limiting end.

[0011] According to the technical solution provided in the embodiments of this application, the end of the second slider that is relatively close to the box cover is set as an inclined surface, and the distance between the inclined surface and the second slide groove along the second direction gradually increases in the launching direction of the simulated rocket body.

[0012] According to the technical solution provided in the embodiments of this application, a first hinge seat is provided on the launch box body, and a first hinge hole is provided on the first hinge seat extending along the first direction. A second hinge seat is provided on the box cover, and a second hinge hole is provided on the second hinge seat arranged along the first direction. The hinge shaft passes through the first hinge hole and the second hinge hole, so that the box cover and the launch box body are hinged together.

[0013] According to the technical solution provided in the embodiments of this application, the second hinge seat includes two blocking portions arranged along the first direction on the side relatively away from the box cover, and the second hinge hole is provided on the blocking portions, the blocking portions being used to limit the opening angle of the box cover.

[0014] Compared with the prior art, the beneficial effects of this application are as follows: The rocket vertical launch box of this application includes a launch box body, a first space that can accommodate a simulated rocket body is provided in the launch box body, the first space has a first opening, and a box cover that is hinged to the launch box body and can open or close the first opening. A snap-fit ​​plate is also provided on the box cover. A launch unit is slidably connected to the inner side wall of the launch box body. The launch unit includes a connecting structure and a simulated rocket body. The connecting structure has a first state and a second state. When it is in the first state, the connecting structure is fixedly connected to the simulated rocket body. When it is in the second state, the connecting structure is slidably connected to the simulated rocket body, and the simulated rocket body can be separated from the connecting structure.

[0015] Under the influence of the gas flow at the bottom of the simulated rocket body, the launching unit moves upward. During this upward movement, one end of the connecting structure collides with the lower surface of the cover. The impact causes the cover to separate from the launch box body, resulting in the cover flipping outward around the first axis. This changes the first opening from a closed state to an open state. The connecting structure continues to move upward with the simulated rocket body. At this point, the snap-fit ​​plate on the cover is in a horizontal state. When one end of the connecting structure abuts against the snap-fit ​​plate, the connecting structure stops moving upward. Under the action of the snap-fit ​​plate, the connection between the connecting structure and the simulated rocket body changes from a fixed connection to a sliding connection. Therefore, the simulated rocket body can continue to move upward. Under its own weight, the connecting structure moves in the opposite direction of the simulated rocket body's launch until it falls back into the launch box body. Simultaneously, the simulated rocket body flies out of the first space under the influence of the gas flow. The structure described in this application ensures that the simulated rocket body will not shatter the cover when it flies out of the first space; only the first opening needs to be kept open, thus enabling the reuse of the cover.

[0024] To enable those skilled in the art to better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings. The description in this section is only exemplary and explanatory, and should not be used to limit the scope of protection of this application.

[0025] With the increasing demand for vertical launch of space rockets at sea and on land, and the continuous increase in launch density, higher requirements are placed on the function of rocket launch boxes. Existing rocket launch boxes in the current technology all use fragile covers, which are opened in a destructive way. However, this method of opening means that the launch box cover cannot be reused after it is opened, resulting in a waste of materials.

[0026] Therefore, the purpose of this application is to address the above problems by providing a vertical launch box for rockets, so that the box cover is not damaged after the rocket is launched vertically and can be reused. The vertical launch box for rockets provided by this application includes:

[0027] The launch box body 1 has a first space inside for accommodating the simulated rocket body 2, and the first space has a first opening.

[0028] The box cover 3 has one side hinged to the launch box body 1, and the axis of its hinge axis 4 is in the first direction. The box cover 3 can be opened or closed around the hinge axis 4. A snap-fit ​​plate 5 is provided on the inner wall of the box cover 3 away from the hinge axis 4.

[0029] A launch unit is slidably connected to the inner wall of the launch box body 1. The launch unit includes a connecting structure and a simulated rocket body 2 disposed on the connecting structure. The connecting structure has a first state and a second state. When it is in the first state, the connecting structure is fixedly connected to the simulated rocket body 2. When it is in the second state, one end of the connecting structure abuts against the snap-fit ​​plate 5, the simulated rocket body 2 is slidably connected to the connecting structure, and the simulated rocket body 2 can be separated from the connecting structure.

[0030] Specifically, in this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, Figure 3 for Figure 1 The enlarged view at point A shows that the rocket vertical launch box includes a launch box body 1. A first space is provided within the launch box body 1 to accommodate a simulated rocket body 2. In this embodiment, the simulated rocket body 2 is cylindrical. The first space has a first opening. A box cover 3 is hinged to one side of the launch box body 1. The other three edges of the box cover 3 are fixed to the launch box body 1 using shear screws. The axis of its hinge axis 4 is in the first direction. The box cover 3 can open or close the first opening. A snap-fit ​​plate 5 is provided on the inner wall of the box cover 3. The snap-fit ​​plate 5 is located on the side of the box cover 3 relatively away from the hinge axis 4 and extends along the rocket launch direction. Figure 7 As shown, when the first opening is closed, the snap-fit ​​plate 5 is inside the first space; when the first opening is open, the snap-fit ​​plate 5 comes out from inside the first space. A launching unit is slidably connected to one of the side walls inside the launching box body 1. The launching unit can detach from inside the first space. The launching unit includes a connecting structure and the simulated rocket body 2 disposed on the connecting structure. The connecting structure has a first state and a second state. When the connecting structure is in the first state, the connecting structure and the simulated rocket body 2 are fixedly connected together using shear screws. When the connecting structure is in the second state, one end of the connecting structure abuts against the snap-fit ​​plate 5, and the relationship between the simulated rocket body 2 and the connecting structure changes from a fixed connection to a sliding connection. Furthermore, the simulated rocket body 2 continues to move along the launching direction and gradually separates from the connecting structure.

[0031] This process is described in detail as follows: When the launching unit is not firing, the launching unit and the launching box body 1 are in a sliding connection relationship and are stationary in the first space. When the launching unit is about to fire, a gas flow will be generated at the bottom of the simulated rocket body 2. Because the connecting structure is in the first state at this time, the connecting structure and the simulated rocket body 2 are in a fixed connection relationship. Therefore, the connecting structure will move upward with the simulated rocket body 2. During the upward movement, one end of the connecting structure will collide with the lower surface of the box cover 3. Due to the impact of the connecting structure, the shear screw of the box cover 3 breaks, and the box cover 3 rotates relative to the launching box body 1, thereby switching the first opening from the closed state to the open state. The connecting structure and the simulated rocket body 2 continue to move upward. At this time, the box cover 3... When the latching plate 5 is in a horizontal state, and one end of the connecting structure abuts against the latching plate 5, the connecting structure switches from a first state to a second state under the obstruction of the latching plate 5. That is, under the blocking force of the latching plate 5, the connection between the connecting structure and the simulated rocket body 2 changes from a fixed connection to a sliding connection. The connecting structure no longer moves upward, while the simulated rocket body 2 continues to move upward under the action of the gas flow. Because the connecting structure and the simulated rocket body 2 are in a sliding connection relationship, they can move relative to each other. Therefore, the connecting structure will move downward along the side wall of the launch box body 1 under its own gravity, that is, in the opposite direction to the launch direction. The simulated rocket body 2 continues to move upward, and the simulated rocket body 2 will separate from the connecting structure and fly out of the first space.

[0032] During use, the launching unit moves upward under the action of the gas flow at the bottom of the simulated rocket body 2. During the upward movement, one end of the connecting structure collides with the lower surface of the box cover 3. Due to the impact of the connecting structure, the box cover 3 separates from the launching box body 1, causing the box cover 3 to flip outward around the first axis, thus switching the first opening from a closed state to an open state. The connecting structure continues to move upward with the simulated rocket body 2. At this time, the snap-fit ​​plate 5 on the box cover 3 is in a horizontal state. When one end of the connecting structure abuts against the snap-fit ​​plate 5, the connecting structure stops moving upward. Under the action of the snap-fit ​​plate 5, the connection relationship between the connecting structure and the simulated rocket body 2 changes from a fixed connection to a sliding connection. Therefore, the simulated rocket body 2 can continue to move upward. Under its own gravity, the connecting structure moves in the opposite direction of the launch of the simulated rocket body 2 until it falls back into the launching box body 1. At the same time, the simulated rocket body 2 flies out of the first space under the action of the gas flow. With the structure described in this application, the simulated rocket body 2 will not break the box cover when it flies out of the first space, thus enabling the reuse of the box cover.

[0033] Furthermore, the connection structure includes a connector, which has a first groove 7 extending along the firing direction of the simulated rocket body 2, a first mounting hole 8 on the first groove 7, a first slider 9 on the simulated rocket body 2, and a second mounting hole 10 on the first slider 9. The first groove 7 is slidably connected to the first slider 9, and the first mounting hole 8 and the second mounting hole 10 are fixedly connected by a shear screw. The shear screw can break after being subjected to external force, and the connection structure switches from the first state to the second state.

[0034] Specifically, in this embodiment, such as Figure 4 , Figure 5 , Figure 6 As shown, the connecting structure includes a connector with a first groove 7 extending along the firing direction of the simulated rocket body 2. A first mounting hole 8 is provided on the side wall of the first groove 7. A first slider 9 is provided on the simulated rocket body 2, and a second mounting hole 10 is provided on the first slider 9. The second mounting hole 10 can be through the first slider 9 or not, and both can be connected using a shear screw. The first slider 9 is slidably connected to the first groove 7. The shear screw can break under external force, but its weakest point should be between the first mounting hole 8 and the second mounting hole 10. At the connection point, this ensures that the shear screw can break under external force, causing the connection between the connecting structure and the simulated rocket body 2 to change from a fixed connection to a sliding connection. When the connecting structure abuts against the snap-fit ​​plate 5 on the box cover 3, the shear screw breaks due to the blocking effect of the snap-fit ​​plate 5, thus changing the connection between the connector and the simulated rocket body 2 to a sliding connection. Therefore, the simulated rocket body 2 can continue to move under the action of the gas flow. Under its own weight, the connector moves in the opposite direction to the launch direction of the simulated rocket body 2, so the simulated rocket body 2 can separate relative to the connector and leave the first space.

[0035] Furthermore, the side of the connector away from the first slide groove 7 is provided with a second slider 11 extending along the launch direction, and the inner sidewall of the launch box body 1 is provided with a second slide groove 12 extending along the launch direction, and the second slider 11 is slidably connected to the second slide groove 12.

[0036] Specifically, in this embodiment, a second slider 11 extending along the firing direction of the simulated rocket body 2 is provided on the side of the connector away from the first slide groove 7. A second slide groove 12 extending along the firing direction is provided on the inner side wall of the launch box body 1 at a location corresponding to the second slider 11. The second slider 11 has a boss shape, and the second slide groove 12 also has a boss shape. The long side of the second slider 11 is inserted into the interior of the second groove 12, thereby ensuring that the second slider 11 and the second slide groove 12 can only slide relative to each other along the firing direction.

[0037] Furthermore, inside the box cover 3, on the side relatively close to the hinge shaft 4, there are two limiting members arranged along the first direction. The two limiting members and the hinge shaft 4 are arranged along the second direction, and the limiting ends of the two limiting members are set close to each other. The second direction is perpendicular to the first direction. On the side of the connector corresponding to the limiting members, there is a receiving groove 13 extending along the firing direction for accommodating the limiting members. The receiving groove 13 has an abutting part 14 at the end relatively close to the box cover 3. When the connector moves in the opposite direction to the firing direction under the action of the snap-fit ​​plate 5 and its own weight, the abutting part 14 abuts against the limiting members, so that the box cover 3 closes the first opening.

[0038] Specifically, in this embodiment, such as Figure 7 As shown, two limiting members are provided inside the box cover 3 on the side relatively close to the hinge shaft 4. The two limiting members are arranged along the first direction, and both the two limiting members and the hinge shaft 4 are arranged along a second direction, which is perpendicular to the first direction. Each limiting member has a limiting end, and the limiting ends of the two limiting members are arranged relatively close to each other, as shown. Figure 6 As shown, a receiving groove 13 is provided on the side of the connector corresponding to the limiting member. The two receiving grooves 13 are symmetrically arranged and both of the receiving grooves 13 extend along the launching direction. The receiving groove 13 is used to accommodate the limiting member. The receiving groove 13 is U-shaped. The end of the receiving groove 13 away from the opening end has an abutment part 14. When the connector abuts against the snap plate 5, the connector will move downward under its own weight. When the abutment part 14 abuts against the limiting part, the box cover 3 will move around the first axis in the opposite direction to the flipping direction under the weight of the connector, thereby closing the first opening. Under the structure described in this application, it can be ensured that the box cover 3 will not break during the opening and closing process, thereby realizing the reuse of the box cover 3.

[0039] Furthermore, the limiting member includes a limiting plate 15 extending in the opposite direction to the launching direction, and a limiting shaft 16 is provided on one side of the limiting plate 15 that is close to each other. The limiting shaft 16 extends in the first direction and has the limiting end.

[0040] Specifically, in this embodiment, such as Figure 7 As shown, the limiting member includes a limiting plate 15, which extends in the opposite direction to the launching direction. The limiting plate includes a first mounting portion 151, which is connected to the bottom surface of the box cover 3. A second mounting portion 152 is provided on the side of the first mounting portion 151 away from the box cover 3. The second mounting portion 152 is rectangular in shape. A limiting shaft 16 is provided on the side of the second mounting portion 152 that is relatively close to each other. The two limiting shafts 16 extend along the first direction and are arranged in a row. The distance between the two limiting shafts 16 is slightly greater than the distance between the two receiving grooves 13 along the first direction. This ensures that the two limiting shafts 16 are inside the receiving grooves 13, and at the same time, the two limiting shafts 16 do not obstruct the movement of the connecting member.

[0041] Furthermore, the second slider 11 is provided with an inclined surface at one end relative to the box cover 3, and the distance between the inclined surface and the second slide groove 12 along the second direction gradually increases in the launching direction of the simulated rocket body 2.

[0042] Specifically, in this embodiment, such as Figure 5 As shown, the end of the second slider 11 that is relatively close to the box cover 3 is set as an inclined surface. The distance between the inclined surface and the second slide groove 12 along the second direction gradually increases in the launching direction of the simulated arrow body 2. This ensures that the connecting member will not be obstructed by the hinge shaft 4 during the upward movement, and that the connecting member can slide upward a certain distance with the simulated arrow body 2.

[0043] Furthermore, a first hinge seat 17 is provided on the launch box body 1, and a first hinge hole 18 extending along the first direction is provided on the first hinge seat 17. A second hinge seat 19 is provided on the box cover 3, and a second hinge hole arranged along the first direction is provided on the second hinge seat 19. The hinge shaft 4 passes through the first hinge hole 18 and the second hinge hole, so that the box cover 3 is hinged to the launch box body 1.

[0044] Specifically, in this embodiment, such as Figure 4As shown, a first hinge seat 17 is provided on the launch box body 1, and a first hinge hole 18 extending along the first direction is provided on the first hinge seat 17. A second hinge seat 19 is provided on the box cover 3, and two second hinge holes arranged along the first direction are provided on the second hinge seat 19. When the launch box body 1 and the box cover 3 are installed, the first hinge hole 18 and the second hinge hole are aligned, and then the hinge shaft 4 is moved along the first direction, so that the first hinge hole 18 and the second hinge hole can be installed together, thereby enabling the box cover 3 and the launch box body 1 to be hinged together.

[0045] Furthermore, the second hinge seat 19 includes two blocking portions 20 arranged along the first direction on the side relatively away from the box cover 3, and the second hinge hole is provided on the blocking portion 20. The blocking portion 20 is used to limit the opening angle of the box cover 3.

[0046] Specifically, in this embodiment, such as Figure 7 As shown, the second hinge seat 19 includes two blocking parts 20 and a connecting part 21 disposed on the side relatively away from the lid 3. The connecting part 21 is used to fix the blocking parts 20 on the lid 3. The two blocking parts 20 are arranged along the first direction. The second hinge hole is disposed on the blocking part 20. The blocking part 20 is used to limit the opening angle of the lid 3. The blocking part 20 and the hinge shaft 4 are fixedly connected, that is, the hinge shaft 4 and the blocking part 20 will rotate together with the lid 3. By providing the blocking part 20, the situation where the lid 3 cannot be closed due to excessive rotation angle when it is opened can be avoided.

[0047] Working principle: When the launching unit is not firing, it is slidably connected to the launching box body 1 and remains stationary within the first space. When the launching unit is about to fire, a gas flow is generated at the bottom of the simulated rocket body 2. Because the connecting structure is in the first state at this time, and the connecting structure is fixedly connected to the simulated rocket body 2, the connecting structure will move upward along with the simulated rocket body 2. During the upward movement, one end of the connecting structure will collide with the lower surface of the box cover 3. Due to the impact of the connecting structure, the shear screw of the box cover 3 breaks, and the box cover 3 rotates relative to the launching box body 1, thereby switching the first opening from the closed state to the open state. The connecting structure and the simulated rocket body 2 continue to move upward. At this time, the snap-fit ​​plate 5 on the box cover 3 is in a horizontal state. When one end of the connecting structure abuts against the snap-fit ​​plate 5, the connecting structure switches from the first state to the second state under the obstruction of the snap-fit ​​plate 5. That is, under the blocking force of the snap-fit ​​plate 5, the connection between the connecting structure and the simulated rocket body 2 changes from a fixed connection to a sliding connection. The connecting structure no longer moves upward, while the simulated rocket body 2 continues to move upward under the action of the gas flow. Because the connecting structure and the simulated rocket body 2 are in a sliding connection relationship, they can move relative to each other. Therefore, the connecting structure will move downward along the side wall of the launch box body 1 under its own gravity, that is, in the opposite direction to the launch direction. The simulated rocket body 2 continues to move upward, and the simulated rocket body 2 will separate from the connecting structure and fly out of the first space. The connecting piece moves in the opposite direction to the launch direction of the simulated rocket body 2 under its own gravity, that is, downward. During the downward movement of the connecting piece, the abutment part 14 on the receiving groove 13 on both sides will touch the limiting shaft 16, thereby driving the box cover 3 to move around the first axis in the opposite direction to its flipping direction, thereby closing the first opening.
