[0003] With the popularity of drones and the threat of attacks, anti-low-altitude drone technology has become a key technology for security. Among the existing technologies, the Chinese invention patent application (application number: 202210950508.2) discloses a design of energetic micro-projectile shrapnel for "low, slow, and small" drone swarm targets. It has strong destructive ability and is suitable for emergency treatment of close-range targets, but cannot solve long-range shooting targets. It is not convenient to select the projectile coverage area suitable for different ranges.

[0004] The Chinese invention patent application (application number: 202311416523.X) discloses a non-lethal kinetic shotgun with controllable dispersion of projectiles. It is large in size and suitable for emergency treatment of living targets at close range. It cannot solve the problem of long-range shooting targets and is not suitable for countering drone attacks.

[0005] The above technologies have difficulties in dealing with long-range drone attacks in actual combat. This shrapnel bomb is designed to solve the above problems. It is also the safest and most secure tactical achievement in dealing with explosives at a long distance. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that the current shrapnel bullet is not convenient for selecting the projectile coverage area suitable for different ranges and cannot solve the problem of controllable area coverage of long-distance shooting targets. The present invention provides a shrapnel bullet that can hit both close-range targets and long-range targets, and can also achieve continuous shooting and concentrate firepower, so as to effectively hit the target.

[0007] The above-mentioned object of the present invention is achieved by the following technical solutions: A blooming bullet includes a spring-expanded blooming bullet and a spring-detonated blooming bullet. The spring-expanded blooming bullet includes a shell, a primer, propellant powder, and a bullet; the bullet is a spring-expanded blooming bullet, and includes a bullet shell, a base, a compression spring, a torsion spring, a basin-shaped spacer, a spring nail, and a marble; the bullet shell is assembled through the compression spring, the torsion spring, and the buckle to form a bullet-shaped bullet, and a plurality of spring nails and a plurality of marbles are assembled in the bullet shell chamber.

[0008] The first concave annular groove is provided at the outer circle of the tail of the bullet shell, and the portion thereof is an outer cone surface upward and an outer step surface downward. The base is shaped like a barrel, and the first inward convex annular step at the round mouth portion thereof is an inner cone surface upward and an inverted surface downward. The first inward convex annular step is assembled with the first concave annular groove, the inner cone surface is adapted to the outer cone surface, and the inverted surface is adapted to the outer step surface. Three or four open gaps are arranged circumferentially at the round mouth end of the base to facilitate elastic assembly and impact deformation and shedding. The second inward convex annular step of the base is between the bottom and the round mouth, and its upward annular step surface and the tail annular end face of the bullet shell are provided with a collision travel distance for launching.

[0009] The bullet shell comprises a first valve shell and a second valve shell, the first valve shell and the second valve shell have the same structure, a double convex plug-in piece is provided on one side of the first valve shell, and a single convex plug-in piece is provided on the other side, the double convex plug-in piece of the second valve shell is inserted on both sides of the single convex plug-in piece of the first valve shell, and the single convex plug-in piece of the first valve shell is inserted between the double convex plug-in pieces of the second valve shell, the single convex plug-in piece and the double convex plug-in piece are tightly fitted and assembled and are arranged inside the bullet shell, the single convex plug-in piece and the double convex plug-in piece are inserted and assembled in opposite and staggered directions, an inward convex annular step is provided at the tail of the chamber of the bullet shell, the first support bow of the torsion spring is assembled at the lower end of the inward convex step of the first valve shell, and the second support bow of the torsion spring is assembled at the lower end of the inward convex step of the second valve shell, The upper end of the spring is in contact with the first support bow and the second support bow of the torsion spring and is subjected to force. The spiral coil part of the torsion spring is assembled inside the spiral coil of the compression spring. The lower end of the compression spring is in contact with the bottom of the base and is subjected to force. The minimum distance between the spiral coil part of the lower end of the torsion spring and the bottom of the base is greater than the collision travel distance of the second inward convex circular ring step. A second concave ring groove is provided on the outer circle of the tail of the bullet shell, which is tightly fitted and assembled with the hub of the shell mouth. The upper end face of the inward convex circular ring step at the tail of the bullet shell chamber is in contact with the bottom of the basin-shaped partition for positioning. A plurality of spring nails are assembled in an array in the chamber on the upper part of the basin-shaped partition, a plurality of marbles are assembled in an array at the upper end of the chamber, and an adaptive conical head or spherical marble is assembled at the tip.

[0010] The compression spring part in the chamber of the bullet is filled with color powder to facilitate observation of the impact point. The bullet is equipped with a circular spacer between the array part of the pins and the array part of the marbles.

[0011] The static pressure of the compression spring after assembly is 100 grams to 500 grams, and different ranges of blooming can be set to cover shooting targets. For example, the static pressure of the compression spring after assembly is 100 grams, 200 grams, 300 grams, and 500 shells, and the corresponding supporting and assembled torsion spring has a force of 300 grams to 1000 grams, such as the force of the first support bow of the torsion spring on the first petal shell is 300 grams, 500 grams, 700 grams, and 1000 shells. After the corresponding compression spring and torsion spring are assembled in the warhead, the corresponding range blooming mark is marked on the outer surface of the warhead shell according to the size of the spring rigidity. The greater the rigidity of the compression spring and torsion spring, the smaller the range of blooming.

[0012] Since the sound made when the bullet explodes is tiny, it can also be used as a secret signal. For example, a rubber balloon containing odor liquid is installed in the bullet shell, and a nail is also installed in the rubber balloon. The inertia of the nail is used to puncture the rubber balloon to release the odor liquid in the target area, thereby transmitting pre-formulated tactical plan information. Signal transmission can be achieved to scouts in hidden trenches or infiltrating enemy interiors, and signal transmission can also be achieved at night.

[0013] The spring-detonated blooming bullet comprises a shell, a primer, propellant powder and a warhead. The warhead is a spring-detonated blooming bullet, and comprises a bullet shell, a base, a compression spring, a flint, a wire saw, a nest-shaped cover, explosives, spring nails and marbles. The front end of the bullet shell is provided with a plurality of slit petals arranged circumferentially to form a conical head to reduce wind assistance. Inside the bullet shell, from top to bottom, there are a plurality of marbles or spring nails, a sealing film, explosives, and a flint. The flint is provided with a through hole and passes through a wire saw. The lower end of the wire saw passes through the through hole at the bottom of the bullet shell and extends through the compression spring and then through the center hole of the base. The part protruding outside the center hole is a buckle flat groove, and the buckle flat groove part is assembled and fixed on the opening gap of the buckle clip. The lower end of the outer side of the base is provided with a convex ring concave ring groove assembled with a nest-shaped cover for sealing. The lower ends of the buckle clip and the buckle flat groove part of the wire saw are assembled inside the nest-shaped cover, and the compression spring is compressed between the bottom of the bullet shell and the base.

[0014] The first concave annular groove is arranged at the tail of the bullet shell, and the outer conical surface is upward and the outer step surface is downward. The first inward convex annular step at the round mouth of the base is shaped like a barrel, and the inner conical surface is upward and the undercut surface is downward. The first inward convex annular step is assembled with the first concave annular groove, the inner conical surface is adapted to the outer conical surface, and the undercut surface is adapted to the outer step surface. The round mouth end of the base is arranged with three or four open gaps in a circumferential manner, which is convenient for elastic assembly and impact deformation and shedding. The second inward convex annular step of the base is between the bottom and the round mouth, and its upward annular step surface and the tail annular end face of the bullet shell are provided with a collision travel distance for launch. The opening petal at the front end of the bullet shell is closed into a pointed shape and encapsulated with anti-rust paint.

[0015] The static pressure of the compression spring after assembly is 300 grams to 1500 grams, and different ranges can be set to detonate and cover the shooting target. For example, the static pressure of the compression spring after assembly is 300 grams, 700 grams, 1100 grams, and 1500 grams. The corresponding compression spring is assembled in the warhead and the corresponding range blooming mark is marked on the outer surface of the warhead shell according to the size of the compression spring rigidity. The greater the rigidity of the compression spring, the smaller the range of its detonation.

[0016] Compared with the prior art, the blooming bomb of the present invention has the following beneficial effects: 1. The blooming shell adopts the method of torsion spring to open the first petal shell and the second petal shell to realize blooming and expand the shooting coverage, so that the efficiency of striking the target is improved. The blooming efficiency of different ranges can be obtained according to the rigidity of the torsion spring, and the controllable range striking coverage can be obtained to produce effective striking results.

[0017] 2. The application of this shrapnel technology to shooting enemy drones can improve the effective strike efficiency. For example, if the drone is 100 to 200 meters away, it can be used to create a continuous shooting gun. The shrapnel makes little sound when it is deployed and has a concealed shooting effect. The continuous shooting and concentrated firepower can improve the reliability of destroying the target. 3. This blooming bomb has the advantages of low sound when blooming and concealment. A rubber balloon containing odor liquid can be installed in the chamber of the warhead to serve as an odor signal bomb, which is convenient for scouts who sneak into the enemy to obtain information. The method of imitating animal and plant odors is more reliable and can transmit signals secretly. BRIEF DESCRIPTION OF THE DRAWINGS

The single convex plug-in and the double convex plug-in are tightly fitted and assembled and are both arranged inside the bullet shell. The single convex plug-in and the double convex plug-in are inserted and assembled in opposite directions and staggered. After the first and second valve shells are assembled, the tail of the chamber is provided with an inwardly convex circular step, and the two ends of the steel wire of the torsion spring are bent to form a U-shaped support bow. The first support bow 14 of the torsion spring is installed at the lower end of the inwardly convex step 16 of the first valve shell 5, and the second support bow of the torsion spring 8 is installed at the lower end of the inwardly convex step of the second valve shell. The upper end of the compression spring 6 contacts the first and second support bows of the torsion spring 8 and is subjected to force. The spiral coil part of the torsion spring is assembled inside the spiral coil of the compression spring, and the lower end of the compression spring 6 contacts the base 7 and is subjected to force. The tail outer circle of the first and second valve shells of the bullet shell after assembly is provided with a first concave annular groove. The base 7 is shaped like a barrel, with the first inward convex circular step at its round mouth being an inner conical surface 21 upward and an undercut surface downward. The first inward convex circular step is assembled with the first concave ring groove, the inner conical surface is adapted to the outer conical surface, and the undercut surface is adapted to the outer step 17 surface; four open gaps are arranged circumferentially at the round mouth end of the base to facilitate elastic assembly of the base and impact deformation and shedding; the second inward convex circular step 20 of the base is between the bottom and the round mouth, and its upward circular step surface and the tail annular end face of the warhead shell are provided with a launch collision travel distance of seven millimeters.

The central part is the primer with detonating charge 12, and the shell is equipped with propellant 11 to assemble the warhead 1 for sealing. The tail of the chamber after the first and second valve shells are assembled is provided with an inward convex circular ring step on the upper end face, which contacts and positions with the bottom of the basin-shaped partition 4. Twenty-one bullet nails 3 are arranged in an array in the chamber above the basin-shaped partition, and nine marbles 2 are arranged in an array at the upper end of the chamber, and an adapted spherical marble is arranged at the tip; in order to calibrate the shooting parameters, red iron red powder can also be filled in the compression spring part to facilitate observation of the impact point. A circular spacer is installed between the array part of the pins and the array part of the marbles to facilitate the forward shooting of the tips of the pins when they are spread out.

[0027] In order to make the marbles have enough destructive power, they can also be made into explosives to spray high-energy marbles, such as Figure 4 and Figure 5 As shown, Figure 4 The second embodiment of the invention is a spring-detonated blooming bomb, which includes a shell 9, a primer, a propellant 11, a bullet shell, a compression spring 6, a flint 26, a wire saw 25, an explosive 23, a marble 30, and a nest-shaped cover 29. The front end of the bullet shell of the bullet 22 is provided with six slit petals arranged circumferentially to form a conical head to reduce wind assistance.

[0028] The firing process and shooting principle of the shrapnel bomb of the present invention are: The second embodiment of the flowering bomb of the present invention, a spring-detonated flowering bomb, is used for explanation. Figure 4As shown, in order to make the marbles have enough shooting destructive force, the explosive in the tail chamber of the warhead is detonated when the warhead is shot at the target at high speed, and the high-energy marbles are ejected, which are enough to penetrate the shell of the drone and damage the batteries and components inside, so as to achieve the efficiency of quickly dealing with the threat of drone attacks. The spring-detonated shrapnel bomb is generated by the saw teeth 32 of the wire saw 25 scratching the flint 26 to generate sparks to detonate the explosive 23. The explosion of the explosive forces fifty non-spherical marbles 30 to break through the six gap petals at the front end of the warhead shell. The petals are forced to open, and the marbles are ejected at high speed to shoot the target to achieve a shooting efficiency with controllable coverage.

[0029] After aiming at the target and pulling the trigger, the firing pin hits the primer to detonate the explosive 12 and ignite the propellant 11 from the nozzle. The propellant explodes to generate high-pressure gas, which pushes the socket-shaped cover and the base at the tail of the bullet 22 toward the barrel and shoots out. When the propellant explodes, the high-pressure gas impacts the base and the inner cone slides and expands toward the outer cone, causing the undercut surface of the circular mouth of the base to fail. After the bullet leaves the barrel, the base is separated from the bullet shell due to the thrust of the compression spring. The separation of the base and the thrust of the compression spring cause the wire saw to pass through the flint and detonate the explosive in the bullet shell. The circular end of the base is arranged circumferentially with four open gaps to facilitate elastic assembly and impact deformation and shedding; the upward circular step surface of the second inwardly convex circular step of the base and the tail of the bullet shell are provided with a collision travel distance for firing, which ensures the thrust for shooting the bullet and controls the circular end of the base within a controllable expansion range, ensuring that the bullet is smoothly ejected from the mouth of the shell and that the bullet slides smoothly and instantly through the barrel under the rotation of the rifling.

[0030] Although the present invention is described above in conjunction with the accompanying drawings, the present invention is not limited to the above specific embodiments, which are merely illustrative and not restrictive. For example, the colored powder filled in the bullet chamber can be matched with a variety of colors according to the color of the shooting place, which is convenient for color selection, and the flint can also be replaced by fulminate of mercury. Under the enlightenment of the present invention, ordinary technicians in this field can also make many variations without departing from the purpose of the present invention. All of these belong to the protection of the present invention.
