[0038] The present application will be described below with reference to the accompanying drawings:

[0039] Figure 1 A schematic structural diagram of a box-type device in some embodiments or certain embodiments of the present application is shown. Figure 2 A schematic diagram of a partial structure of a box-type device in some embodiments or certain embodiments of the present application is shown, with reference to Figure 1 and Figure 2 , an embodiment of the present application provides a box-type device, comprising:

[0040] The box body 1 includes a first main body 11 and a second main body 12 that are hinged together. The first main body 11 is provided with a locking hole 111, and the second main body 12 is provided with a strip-shaped sliding hole 121 that passes through the first main body 11.

[0041] The locking shaft 2 is rotatably mounted on the second body 12 and its axis is perpendicular to the length direction of the sliding hole 121 . The locking shaft 2 passes through the locking hole 111 and extends out of the box body 1 . One end of the locking shaft 2 is provided with a rectangular limit block 21 for contacting the first body 11 .

[0042] The slider 3 is slidably engaged with the sliding hole 121 along the length direction of the sliding hole 121 , and is provided with a rod portion 35 whose axis extends along the axial direction of the locking shaft 2 .

[0043] The connecting rod 4 has one end fixed to the locking shaft 2 and the other end passing through the sliding hole 121 and having a strip-shaped hole 41 sleeved on the rod portion 35 .

[0044] At least two stoppers 5 are fixed to the second body 12 at intervals along the length direction of the sliding hole 121 , and are both located on one side of the sliding hole 121 . A limiting groove 7 is formed between two adjacent stoppers 5 .

[0045] One end of the rotating rod 6 is rotatably engaged with the slider 3 and is used to rotate into the limiting groove 7.

[0046] The box body 1 of the box-type device includes a first main body 11 and a second main body 12 that are hinged together. The first main body 11 and the second main body 12 can rotate relative to each other to open or close. A locking hole 111 is provided on the first main body 11. The locking hole 111 can allow a locking shaft 2 rotatably arranged on the second main body 12 to pass through. The locking shaft 2 extends out of the box body 1 and is provided with a rectangular limit block 21 for abutting the first main body 11 at one end. The locking shaft 2 rotates relative to the second main body 12, which can make the rectangular limit block 21 rotate relative to the first main body 11. Different parts of the rectangular limit block 21 can abut against the first main body 11 to achieve locking of the first main body 11 and the second main body 12. The second body 12 is provided with a strip-shaped sliding hole 121, and the axis of the locking shaft 2 is not perpendicular to the length direction of the sliding hole 121. The sliding hole 121 is slidably matched with a slider 3, which is provided with a rod portion 35. One end of the connecting rod 4 is fixed to the locking shaft 2, and the other end of the connecting rod 4 passes through the sliding hole 121 and is provided with a strip-shaped hole 41 that is sleeved on the rod portion 35. When the slider 3 is pushed to move along the length direction of the sliding hole 121, the slider 3 can push the connecting rod 4 where the strip-shaped hole 41 is located to move through the rod portion 35. The connecting rod 4 will rotate around the locking shaft 2, pushing the locking shaft 2 to rotate, so that the locking shaft 2 can rotate until it abuts the first body 11 or rotates until it can pass through the locking hole 111. This simplifies operation, and the other end of the connecting rod 4 is sleeved on the rod portion 35 of the slider 3 through the strip-shaped hole 41. The strip-shaped hole 41 can increase the relative movement range of the slider 3 and the connecting rod 4, and can ultimately convert the sliding translation of the slider 3 into the rotation of the locking shaft 2. At least two stoppers 5, both located on one side of the slide hole 121, are fixed to the second body 12 at intervals along the length of the slide hole 121. A limiting groove 7 is formed between two adjacent stoppers 5. The slider 3 is rotatably engaged with one end of the rotating rod 6. When the slider 3 is moved into position so that the locking shaft 2 can abut against the first body 11, the rotating rod 6 can rotate relative to the slider 3 to enter the limiting groove 7, thereby locking and positioning the locking shaft 2. In the box-type device, the movement of the slider 3 is simple, and the locking shaft 2 can be easily rotated to limit the first body 11 and the second body 12. The limiting groove 7 between the rotating rod 6 and the stopper 5 can complete locking when the locking shaft 2 abuts against the first body 11. Opening can be achieved by reversing the operation. The operation is simple and easy to achieve locking and opening. The time required to open and close the box-type device body 1 is also short. The box-type device can be used as a missile launch box, thereby solving the technical problem of the missile launch box's opening and closing efficiency being affected to a certain extent.

[0047] The slider 3 is rotatably coupled with a rotating rod 6, which also serves as a force application point. By applying force to the rotating rod 6 to push the slider 3, the efficiency of the slider 3 in rotating the locking shaft 2 is improved, which also helps improve the opening and closing efficiency of the missile launch box. At least two stoppers 5 allow the rotating rod 6 to slide between two stoppers 5 at different positions, which also enables rapid locking of the box-type device.

[0048] It should be noted that to open the box 1, the rotating rod 6 is rotated relative to the slider 3, causing the rotating rod 6 to slide out of the retaining groove 7. Pushing the rotating rod 6 or the slider 3 further changes the position of the locking shaft 2, allowing the locking shaft 2 and the rectangular retaining block 21 to pass through the locking hole 111, thereby enabling the first body 11 and the second body 12 to open. The box-shaped device provided in this application is not limited to the manufacture of missile launch boxes, but can also be used to manufacture box-shaped structures that require rapid opening and closing. The locking shaft 2 rotates about its own axis. Figure 1 The structures such as the slider 3 and the rotating rod 6 are omitted.

[0049] It should be noted that the rectangular limit block 21 in the present application can be a relatively regular rectangular limit block 21 in the shape of a cuboid, or it can be a rectangular limit block 21 that is close to a rectangle and has a clearly distinguished length, width and height and is similar to a cuboid.

[0050] In some or certain embodiments, the locking hole 111 is a rectangular hole, and the length of the rectangular limiting block 21 is between the length of the locking hole 111 and the width of the locking block.

[0051] The locking hole 111 is a rectangular hole, and the length of the rectangular limit block 21 is between the length of the locking hole 111 and the width of the locking block, so that the length of the rectangular limit block 21 is less than the length of the locking hole 111, and the width of the rectangular limit block 21 is greater than the width of the locking hole 111. When the rectangular limit block 21 rotates to a certain angle with the locking shaft 2, the length direction of the rectangular limit block 21 is the length direction of the locking hole 111, and the rectangular limit block 21 can be disengaged from the locking hole 111. When the locking shaft 2 rotates to different angles, there is an angle between the length direction of the rectangular limit block 21 and the length direction of the locking hole 111. For example, when the length direction of the rectangular limit block 21 is the width direction of the locking hole 111, the rectangular limit block 21 can be stuck above the locking hole 111 and abut against the first body 11, thereby achieving the relative position of the first body 11 and the second body 12. The preparation is simple and convenient for realizing the opening and closing of the first body 11 and the second body 12.

[0052] For ease of understanding, here is provided Figure 3 and Figure 4 , Figure 3 Schematic diagram showing another locking state of the first body and the second body in some embodiments or certain embodiments of the present application, Figure 4 Schematic diagram showing the opening state of the first body and the second body in some embodiments or certain embodiments of the present application, with reference to Figures 2 to 4 , Figure 2 、 Figure 3 The locking shaft 2 in the embodiment abuts against the first body 11, so that Figure 2 、 Figure 3 The first body 11 and the second body 12 are both in a locked state. Figure 2 、 Figure 3 Only the rotation angle of the locking shaft 2 is different. Figure 4 The rectangular limiting block 21 of the locking shaft 2 can be disengaged from the locking hole 111 , so that the first body 11 can rotate relative to the second body 12 to achieve the rotational opening of the first body 11 and the second body 12 .

[0053] In some or certain embodiments, the locking hole 111 may be a square hole or an oval hole, etc., and when the locking shaft 2 rotates a certain angle, the rectangular limit block 21 may be disengaged from the locking hole 111, or the rectangular limit block 21 may be stuck in the first body 11, thereby achieving separation or locking of the first body 11 and the second body 12.

[0054] In some or certain embodiments, the slider 3 is provided with a mounting through hole 31 with one end opening communicating with the sliding hole 121 , and the rod portion 35 passes through the mounting through hole 31 .

[0055] The rod 35 can be arranged in the mounting through hole 31, and the connecting rod 4 can also pass through the sliding hole 121 into the mounting through hole 31 and then cooperate with the rod 35. The volume occupied by components such as the slider 3 and the connecting rod 4 can be reduced, making it easy to install and use.

[0056] In some or certain embodiments, the mounting hole 31 may be a rectangular hole, the pin is inserted into the slider 3, and the pin traverses the mounting hole 31, and the portion of the pin located in the mounting hole 31 may be configured as a rod 35, so as to facilitate the disassembly and replacement of the structure.

[0057] In some or certain embodiments, the slider 3 may also have two spaced protrusions protruding from the slider 3, the rod 35 being plugged into the two protrusions, and the connecting rod 4 being sleeved on the rod 35 through the strip-shaped hole 41. The movement of the slider 3 may also be transferred to the connecting rod 4, ultimately enabling the locking shaft 2 to rotate.

[0058] In some or certain embodiments, the second body 12 includes:

[0059] The rotating portion 122 is in the shape of a box with one end open, and one end of the locking shaft 2 is rotatably connected to the inner wall of the rotating portion 122 .

[0060] The mounting portion 123 is detachably connected to the outer wall of the rotating portion 122 and is located on one side of the opening. The sliding hole 121 is provided in the mounting portion 123 , and the other end of the connecting rod 4 passes through the rotating portion 122 and the sliding hole 121 in sequence.

[0061] The second body 12 adopts the above configuration to facilitate installation of the slider 3 and transfer the sliding hole 121 to the detachable mounting portion 123. The box-type device can also be quickly repaired by replacing the mounting portion 123 and the slider 3.

[0062] It should be noted that one end of the connecting rod 4 can be connected to the locking shaft 2 located in the rotating part 122, and a hole corresponding to the connecting rod 4 and the sliding hole 121 will be set on the open side of the rotating part 122. The other end of the connecting rod 4 can pass through the hole of the rotating part 122 and the sliding hole 121 in sequence, and then be inserted into the mounting through hole 31 of the slider 3, and finally the rod part 35 is inserted into the bar hole 41 of the connecting rod 4.

[0063] In some or certain embodiments, the sliding block 3 and the two side walls of the sliding hole 121 can be slidably fitted together by means of a dovetail groove or a T-slot.

[0064] Figure 5 A schematic diagram showing the structure of a second body in some embodiments or certain embodiments of the present application is shown. Figure 5 In some or certain embodiments, a plate-shaped protrusion 1221 may be provided on the inner wall of the rotating portion 122 , and a nut 1222 is welded to the plate-shaped protrusion 1221 , and the nut 1222 is threadedly engaged with the locking shaft 2 , so as to facilitate the connection and installation of the locking shaft 2 .

[0065] In some or certain embodiments, the inner wall of the rotating portion 122 may also be provided with a block-shaped protrusion, and the locking shaft 2 cooperates with the connecting hole provided in the block-shaped protrusion to achieve rotation.

[0066] In some or certain embodiments, the first body 11 may also include a main body portion 112 and a locking block portion 113. The main body portion 112 is in the shape of a box with one end open. The locking block portion 113 is fixedly connected to the main body portion 112, and the locking hole 111 may be provided in the locking block portion 113. This is beneficial to improving the strength of the first body 11.

[0067] It should be noted that the structure of the main body 112 can refer to the structure of the rotating part 122. The main body 112 is hinged to one side of the rotating part 122. The main body 112 rotates relative to the rotating part 122 to realize the opening and closing of the first body 11 and the second body 12.

[0068] In some or certain embodiments, the length direction of the connecting rod 4 extends along the radial direction of the locking shaft 2, and the length direction of the strip hole 41 extends along the length direction of the connecting rod 4. The connecting rod 4 and the strip hole 41 have high transmission efficiency and occupy a small volume.

[0069] In some or certain embodiments, there may be a certain angle between the length direction of the connecting rod 4 and the length direction of the strip-shaped hole 41 , so as to transfer the movement of the slider 3 to the locking shaft 2 .

[0070] In some or certain embodiments, a stop member 5 is provided with an insertion hole (not shown in the figure) passing through the length direction of the sliding hole 121, and the box-type device also includes a tightening member 8 passing through the insertion hole and rotatingly cooperating with the stop member 5, and the tightening member 8 is provided with a tightening end 81 for abutting against the rotating rod 6.

[0071] The pressing member 8 passes through the insertion hole, and the pressing end 81 of the pressing member 8 can press the rotating rod 6 onto the stopper 5 to improve the connection stability between the first body 11 and the second body 12.

[0072] In some or certain embodiments, the peripheral wall of the rotating rod 6 is provided with a positioning groove 61 for cooperating with the pressing end 81. The positioning groove 61 cooperates with the pressing end 81 to further improve the locking effect of the first body 11 and the second body 12.

[0073] In some or certain embodiments, the pressing member 8 is a spring pin, one end of which is configured as a pressing end 81. It is easy to obtain and simple to operate.

[0074] In some or certain embodiments, the spring pin may be a spring pin with one end being retractable, and the retractable end of the spring pin is configured as a pressing end 81. The retractable end of the spring pin can press against the rotating rod 6, and manually compressing the retractable end of the spring pin can separate the pressing end 81 from the rotating rod 6, so that the rotating rod 6 can be rotated to disengage from the limiting groove 7.

[0075] In some or certain embodiments, the tightening member 8 may also be a bolt that rotates with the socket thread of the stop member 5, so that the bolt rotates relative to the stop member 5, and the bolt can move relative to the stop member 5 to achieve tightening of the rotating rod 6.

[0076] In some or certain embodiments, the slider 3 comprises:

[0077] The body 32 cooperates with the sliding hole 121 and is provided with a rod portion 35 . The body 32 is further provided with a mounting groove that passes through the body 32 along the axial direction of the locking shaft 2 and is spaced apart from the rod portion 35 .

[0078] The sliding rod 33 is connected to the body 32 and extends axially along the length direction of the sliding hole 121 . The sliding rod 33 crosses the mounting groove. One end of the rotating rod 6 is slidably mounted on the sliding rod 33 along the axial direction of the sliding rod 33 .

[0079] The body 32 of the slider 3 is configured to engage with the slide hole 121 and is provided with a rod portion 35. The body 32 is provided with a mounting slot that can be connected to the rotating rod 6, thereby achieving rotational coordination between the rotating rod 6 and the slider 3, and the overall structure is relatively compact. Furthermore, this arrangement of the sliding rod 33 and the rotating rod 6 allows, when the locking shaft 2 rotates until the rectangular stop block 21 abuts the first body 11 and the locking shaft 2 or the slider 3 becomes stuck, the rotating rod 6 can be moved relative to the slider 3 until the slider 3 can rotate relative to the sliding rod 33 and the rotating rod 6 slides into the stop slot 7. This allows the first body 11 and the second body 12 to be locked in various situations, and also reduces the frequency of maintenance required for the box-type device.

[0080] In some or certain embodiments, the sliding rod 33 may be a pin, etc. The sliding rod 33 may be inserted into the body 32 and cross the installation slot. The sliding rod 33 and the body 32 may be connected and fixed by fasteners.

[0081] In some or certain embodiments, the slider 3 further includes a spring 34, which is sleeved around the sliding rod 33, with its ends respectively contacting the sidewalls of the mounting slot and the rotating rod 6. The spring 34 provides a preload force for the rotating rod 6, allowing the rotating rod 6 to be moved to the proper position and then rotated to slide into the retaining slot 7 between the stoppers 5. The spring 34 and the stoppers 5 both exert a force on the rotating rod 6 along the length of the sliding hole 121, facilitating the pressing of the rotating rod 6 against the stoppers 5 and enhancing the locking effect.
