Description

Technical Field

[0001] The present application relates to the technical field of blasting equipment, and particularly relates to a portable launch box for containing a rocket blaster. Background Art

[0002] In related technologies, for some portable launch boxes, the following actions are required when setting the firing angle: after opening the box cover, the support ring is snapped into the anti-recoil mechanism, so that the box cover, the support ring, and the box body form a triangular stable mechanism, thereby ensuring that the launch rail forms a firing angle with the ground.

[0003] The stable mechanism of the above-mentioned portable launch box has many parts and large firing angle errors. When in use, it is necessary to open the lock, pick up the support ring, turn the box cover, and then the support ring is snapped into two thrust mechanisms. The operation requires many actions and a long operation time; at the same time, it is necessary to snap into two thrust mechanisms. If only one thrust mechanism is snapped in by mistake during operation, it will cause the firing angle to exceed the tolerance and tilt, with low reliability and easy to make mistakes, and a long operation time. Utility Model Content

In the description of the present application, the meaning of "multiple", "several" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0045] Refer to Figures 1-6 , the present application provides a portable launch box with a launch device, including:

[0046] A portable launch box with a launch device, including:

[0047] A box body, one end of the box body is open, one side of it is set as the front, and one side is set as the back;

[0048] A box cover which is rotatably installed at the open end of the box body and can be rotated to close the open end of the box body or rotated to the back of the box body to open the open end of the box body. When the box cover is rotated to the back of the box body, the box cover can be connected and fixed to the back of the box body through a first position maintaining structure or a second position maintaining structure installed thereon to form different launch angles;

[0049] A launch rail which is installed on the front of the box body and extends from the other end of the box body towards its open end; and

[0050] A flying device which is alternatively detachably installed on the launch rail or in the box body. When the flying device is installed on the launch rail, the flying device is detachably connected to the box body or the box cover through a flexible connecting member, and the flying device can fly away along the launch rail from the open end of the box body.

[0051] Specifically, when carrying, place the flying device in the box body and load other required spare items in the box body. When launching is required, open the box cover and firmly connect and fix the box cover to the back of the box body through the first position maintaining structure or the second position maintaining structure when the box cover is opened. Next, tilt the box body so that its back faces the ground, and place both the opened side of the box cover and one end of the corresponding closed end of the back of the box body on the ground. At this time, an angle α (as shown in Figure 2 、 3 ) will be formed between the back of the box body (the box body is rectangular parallelepiped-shaped and its back is a plane) and the ground, where 25° ≤ α ≤ 30°, that is, the launch rail is at a launch inclination angle of 25° - 30°, and this inclination angle is the optimal flight launch angle of the flying device.

[0052] Referring to Figures 1-6 , it can be understood that the first position maintaining structure is a self-locking hinge 300 which is used to connect the box body 1 and the box cover 2. The self-locking hinge includes a support 320, a shaft page 310 is rotatably connected to the support 320, an arc-shaped groove 321 is provided on the support 320, an opening groove 322 is provided at one end of the arc-shaped groove 321, a sliding pin 330 and a pressing pin 340 are provided on the shaft page 310, the pressing pin 340 is slidably sleeved on the sliding pin 330, the pressing pin 340 is connected to the sliding pin 330 through a spring 350, the diameter of the first section 341 of the pressing pin 340 is smaller than that of the second section 342, only the first section 341 of the pressing pin 340 can pass through the arc-shaped groove 321 and slide in the arc-shaped groove 321, and both the first section 341 and the second section 342 of the pressing pin 340 can pass through the opening groove 322;

[0053] When the box cover 2 rotates to the back of the box body 1, the first section 341 of the press pin 340 slides in the arc-shaped groove 321 into the opening groove 322, and under the action of the spring 350, the first section 341 and the second section 342 of the press pin 340 pass through the opening groove 322, and the second section 342 of the press pin 340 catches the arc-shaped groove 321, so that the box cover 2 is fixed on the back of the box body 1.

[0054] Specifically, the support 320 is installed on the back of the box body 1, the hinge 310 is installed on the box cover 2, and the hinge 310 and the box body 1 can be connected by means of a rotating shaft, rivets, etc., so that the hinge 310 can freely rotate on the support 320, so that the box cover 2 can freely open and close at the open end of the box body 1. An arc-shaped groove 321 is provided on the side wall of the support 320, and an opening groove 322 communicating with it is provided at the end of the arc-shaped groove 321, and the diameter of the opening groove 322 is larger than the width of the arc-shaped groove 321.

[0055] It should be understood that at least two self-locking hinges 300 are provided between the box body 1 and the box cover 2. When two self-locking hinges 300 are provided, they are divided into a left self-locking hinge 300 and a right self-locking hinge 300. The left self-locking hinge 300 and the right self-locking hinge 300 only have different opening directions of the hinge 310 and the support 320, and the rest of the parts are the same.

[0056] Specifically, referring to Figures 2-6 , one end of the sliding pin 330 away from the press pin 340 is connected to a side wall of the hinge 310, and the press pin 340 passes through the other side wall of the hinge 310. The sliding pin 330 is slidably sleeved in one end of the press pin 340, and a spring 350 is also sleeved on the sliding pin 330. One end of the spring 350 is connected to the press pin 340, and the other end is connected to the hinge 310 or the sliding pin 330. When the press pin 340 is pressed, the press pin 340 can slide on the sliding pin 330 and the spring 350 is compressed. The press pin 340 is divided into a first section 341 and a second section 342. The diameter of the first section 341 is smaller than that of the second section 342. The diameter of the first section 341 is less than or equal to the width of the arc-shaped groove 321 and smaller than the diameter of the opening groove 322. The diameter of the second section 342 is larger than the width of the arc-shaped groove 321 and smaller than the diameter of the opening groove 322, so that the first section 341 can slide in the arc-shaped groove 321, and when the first section 341 slides into the opening groove 322, the press pin 340 can pop out of the opening groove 322 under the action of the spring 350, and the first section 341 and the second section 342 extend out of the opening groove 322, and the second section 342 catches the arc-shaped groove 321.

[0057] In other embodiments, arc-shaped grooves 321 are provided on both side walls of the support 320. The sliding pin 330 is divided into a first section 341 and a second section 342. The diameter of the first section 341 is less than or equal to the width of the arc-shaped groove 321 and less than the diameter of the opening groove 322. The diameter of the second section 342 is greater than the width of the arc-shaped groove 321 and less than the diameter of the opening groove 322. One end of the first section 341 away from the second section 342 passes through one side wall of the shaft leaf 310 and passes through the arc-shaped groove 321 or the opening groove 322. One end of the second section 342 away from the first section 341 passes through the other side wall of the shaft leaf 310 and passes through the arc-shaped groove 321 on the other side of the support 320.

[0058] Refer to Figure 6 , it can be understood that a snap ring 370 is provided on the sliding pin 330. One end of the spring 350 is connected to the snap ring 370, and the other end is connected to the shaft leaf 310.

[0059] Specifically, by providing the snap ring 370, it is equivalent to increasing the diameter of the second section 342 of the sliding pin 330, so that the sliding pin 330 can be better restricted to move inside the shaft leaf 310, preventing the pin shaft from being worn due to long-term use.

[0060] Refer to Figures 2-5 , it can be understood that a button 360 is provided on the press pin 340.

[0061] Specifically, the button 360 is provided at one end of the first section 341 of the press pin 340 away from the second section 342. The size of the button 360 should be greater than the size of the opening groove 322. On the one hand, it can increase the contact area and improve the comfort of pressing; on the other hand, it can prevent the end of the press pin 340 from passing over the opening groove 322 and entering the inside of the shaft leaf 310 when pressing the sliding pin 330, causing inconvenience in subsequent operations.

[0062] Refer to Figure 2 and 3 , it can be understood that the second position holding structure is a trapezoidal frame 21. The shorter bottom edge of the trapezoidal frame 21 is rotatably connected to the outside of the box cover through a rotating seat. When the box cover rotates to the back of the box body, the trapezoidal frame 21 can rotate around the rotating seat to form an angle with the outside of the box cover, and the longer bottom edge of the trapezoidal frame 21 is fixedly connected to the back of the box body. The entire second position holding structure is relatively simple in design, and can quickly fix the box cover to the back of the box body after the box cover is opened, and the operation is relatively convenient.

[0063] It is understandable that buckle members 11 are respectively installed at positions on the back surface of the box body corresponding to both ends of the longer bottom side of the trapezoidal frame body 21, and the longer bottom sides of the trapezoidal frame body 21 are detachably clamped with the buckle members 11.

[0064] Specifically, through the clamping of the trapezoidal frame body 21 and the buckle members 11, the quick disassembly, assembly and separation of the trapezoidal frame body 21 and the back surface of the box body can be realized. The operation is extremely simple, which greatly saves the assembly cycle.

[0065] The buckle member 11 is a conventional product on the market. Specifically, it includes two arc-shaped elastic pieces spaced apart on one side of the seat body. The openings of the two arc-shaped elastic pieces are close to each other, and the ends of the two form an opening for the longer bottom side of the trapezoidal frame body 21 to be extruded through. When an external force is applied to the longer bottom side of the trapezoidal frame body 21, it can be squeezed into the space between the two elastic pieces through the opening.

[0066] Of course, the buckle member 11 can also be other structures or products on the market that can fix a strip-shaped structure.

[0067] It should be understood that as Figure 2 and 3 shown, when the self-locking hinge 300 rotates completely into place and locks, an emission angle α1 can be formed through the support of the box cover 2; when the self-locking hinge 300 does not rotate completely into place and is not locked, the trapezoidal frame body 21 can be snapped into the buckle member 11 to fix the box cover 2 and form an emission angle α2 through the support of the box cover 2. The buckle member can be set at multiple positions, so as to form multiple different emission angles, where α2 is less than α1.

[0068] It is understandable that the flying device is a rocket engine, which is convenient to use, has sufficient power and good flight state.

[0069] It should be emphasized particularly that: the rocket engine and the launch guide rail are both prior arts.

[0070] Referring to Figures 1-3 and 7, 8, a locking member is further arranged between the box cover 2 and the box body 1. The locking member includes:

[0071] A lock plate 500, on which a lock bar 510 forming a lock groove is arranged; and

[0072] A lock plug 400, at the end of which a lock button 410 that can be extended or retracted and is connected by an elastic member 420 is arranged;

[0073] Wherein, when the end of the latch plug 400 is inserted into the lock slot, the latch button 410 is compressed and retracted by the lock bar 510; when the latch button 410 passes over the lock bar 510, the latch button 410 extends under the action of the elastic member 420 to catch the lock bar 510.

[0074] Specifically, one end of the latch button 410 is rotatably connected to the latch plug 400, and the elastic member 420 connects the latch socket and the latch button 410. When opening the box cover 2, press the latch button 410. When the latch button 410 is flush with the latch plug 400, rotate the box cover 2, and the latch plug 400 disengages from the lock bar 510, and the box cover 2 is opened; when closing the box cover 2, rotate the box cover 2 to insert the latch plug 400 into the lock bar 510, the lock bar 510 presses the latch button 410, and the elastic member 420 is stressed; when the latch button 410 enters the lock bar 510, the latch button 410 pops up under the action of the elastic member 420 to prevent the latch plug 400 from sliding out of the lock bar 510; the box cover 2 cannot be opened without pressing the latch button 410. It can be understood that the elastic member 420 can be a coil spring, an elastic sheet or other prior art means capable of popping up the latch button 410.

[0075] Referring to Figure 1 , it can be understood that a shoulder strap 3 is provided on the back of the box body 1. There is at least one shoulder strap, which is installed on the back of the box body 1, facilitating the user to carry and carry on the back, and improving the portability of the portable launch box.

[0076] Referring to Figure 9 , it can be understood that the box body 1 adopts a three-layer composite structure composed of a glass fiber layer 600 - a carbon fiber layer 700 - a glass fiber layer 600; the box cover 2 adopts a three-layer composite structure composed of a glass fiber layer 600 - a carbon fiber layer 700 - a glass fiber layer 600.

[0077] Specifically, the box body 1 and the box cover 2 adopt a multi-layer fiber structure, which can reduce the overall weight on the one hand and effectively improve the overall strength on the other hand.

[0078] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the principle of the present application shall be included in the protection scope of the present application.
