Description

Technical Field

[0001] This invention relates to the field of bullet recovery technology, and in particular to a safe horizontal bullet collector. Background Technology

[0002] A bullet collector is a device that uses water as a damping medium to collect bullets fired from a firearm. After a bullet enters the collector through the firing port at one end, the water in the collector exerts significant damping on the bullet, causing it to lose kinetic energy and fall into the collector. This process maximizes the preservation of the bullet's characteristics, preventing secondary damage. These preserved characteristics can be used to analyze the bullet's origin and are widely used in criminal investigations.

[0003] When a bullet enters the water within the bullet collector, the significant kinetic energy generated upon ejection impacts the water, increasing the pressure within the collector. This pressure is then transferred to the collector itself. As illustrated in the horizontal bullet collector disclosed in CN120141239A, some of the water within the collector flows out from the firing port, thus providing pressure relief. However, due to the small size of the firing port, the pressure relief capacity is limited. While this may be significant for small-caliber pistols, it is crucial to consider the greater kinetic energy generated by large-caliber rifle bullets. This results in greater pressure on the water within the collector, significantly limiting its pressure relief capability. Excessive pressure within the collector can cause it to expand and deform, compromising safety. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a safe horizontal bomb collector, which solves the problem that the limited pressure relief capacity of the horizontal bomb collector affects the safety of use.

[0005] The technical solution of the present invention to achieve the above objectives is a safety-type horizontal ammunition collector, including a pressure-reducing device installed at a pressure relief port on the ammunition collector body, the pressure-reducing device comprising: A connecting plate, which is tightly attached to the inner wall of the horizontal projectile collector; The base plate is attached to the outer wall of the horizontal bomb collector. The base plate and the connecting plate are fixedly connected by bolts. A sealing structure is provided between the base plate and the outer wall of the horizontal bomb collector. Water outlet holes corresponding to the pressure relief ports on the connecting plate and the base plate are provided. A sealing plate, which is attached to the substrate; Multiple guide members are arranged in a circumferentially and evenly around the water outlet hole on the substrate. One end of each guide member is fixedly connected to the substrate, and the other end is inserted into the sealing plate. Multiple springs, each corresponding to a guide member and sleeved on the respective guide member, are used to apply a uniform clamping force to the sealing plate, so that the sealing plate is tightly attached to the base plate to block the water outlet.

[0006] To facilitate the installation of the connecting plate and the base plate on the horizontal base, the connecting plate and the base plate are provided with a number of corresponding mounting holes around the water outlet in the circumferential direction, and each mounting hole is provided with a bolt to connect the connecting plate and the base plate.

[0007] As a preferred embodiment, a sealing ring or gasket is provided between the inner wall of the connecting plate and the horizontal collector, and the sealing ring or gasket has a plurality of circular holes on its circumference that correspond to the mounting holes.

[0008] To increase the sealing performance between the sealing plate and the substrate, a sealing portion is formed on the side of the substrate near the sealing plate, protruding outward in the circumferential direction around the water outlet, and the sealing plate is in close contact with the sealing portion.

[0009] In a preferred embodiment, a sealing groove is provided on the surface of the sealing part that contacts the sealing plate, or on the surface of the sealing plate that contacts the sealing part, and a sealing ring is provided in the sealing groove.

[0010] To facilitate the installation of guide bolts, multiple bolt holes are provided on the base plate. These bolt holes are evenly distributed around the circumference of the sealing part, and the guide bolts are fixed in the bolt holes.

[0011] In a preferred embodiment, a plurality of countersunk holes are provided on the side of the substrate away from the sealing plate, the head of the guide bolt is hidden in the countersunk holes, and a guide bolt is provided in each bolt hole.

[0012] As a preferred embodiment, an adjusting nut is provided at one end of the guide bolt away from the base plate for adjusting the amount of clamping force applied by the spring to the sealing plate.

[0013] To facilitate the positioning of the sealing plate, four positioning portions are formed on the side of the sealing plate closest to the substrate, which are respectively corresponding to the four corners of the water outlet on the substrate. The surface of the positioning portion that contacts the inner wall of the water outlet on the substrate is an inclined surface.

[0014] In a preferred embodiment, an annular sealing block is formed on the side of the sealing plate near the substrate, protruding outward in the circumferential direction around the water outlet hole on the substrate. The cross-sectional size of the sealing block gradually decreases in the direction away from the sealing plate, and the maximum cross-sectional size of the sealing block is larger than the size of the water outlet hole on the substrate, while the minimum cross-sectional size is smaller than the size of the water outlet hole on the substrate.

[0015] Its advantages over existing technologies are: The safety-type horizontal bomb collector provided in this invention is equipped with a pressure-reducing device, which has the advantages of simple structure and easy installation and disassembly. The main structure of the pressure-reducing device is fixedly installed at the pressure relief port of the bomb collector by sequentially passing bolts through a connecting plate, the bomb collector, and a base plate located inside the bomb collector. The base plate is located outside the bomb collector, and a sealing structure is provided between the two to ensure airtightness and prevent water inside the bomb collector from leaking through the gap between the bomb collector and the base plate. Both the connecting plate and the base plate have corresponding water outlet holes. The sealing plate can be moved relative to the base plate via a guide member. Multiple springs sleeved on the guide member apply a uniform clamping force to the sealing plate, causing the sealing plate to adhere tightly to the base plate and block the water outlet holes. When the internal pressure of the bomb collector increases and exceeds the clamping force applied by the spring to the sealing plate, the sealing plate will be opened, the water outlet will open, and some of the water inside the bomb collector will be discharged, reducing the internal pressure of the bomb collector. When the pressure drops to a certain level, the sealing plate will return to its original position under the action of the spring, and the water outlet will be blocked again. In this way, the pressure of the bomb collector is automatically reduced, preventing the bomb collector from deforming due to the increase in internal pressure.

[0016] The horizontal bomb collector can achieve automatic drainage and pressure reduction through a pressure reduction device, and does not require major modifications to the horizontal bomb collector itself. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] A preferred embodiment of the present invention provides a safe horizontal bomb collector, which mainly includes two parts: a bomb collector body and a pressure relief device. The pressure relief device is installed at the pressure relief port on the bomb collector body 1 and is used for draining water and reducing pressure.

[0021] The horizontal bullet collector 1 is filled with water. The water's damping effect stops the bullets fired from the firearm, and then collects them for archiving. Because the enormous kinetic energy generated when a bullet enters the bullet collector 1 increases the water pressure, a pressure relief device is used to release the pressure in the bullet collector 1 when the pressure exceeds a certain threshold.

[0022] During installation, a pressure relief port will be pre-drilled on the side wall of the bomb collector 1, and then the pressure relief device will be installed at the pressure relief port. Once the water pressure increases to exceed the sealing pressure that the pressure relief device can withstand, the pressure relief device will automatically open to drain and relieve pressure.

[0023] For details, see Figures 1-4 The pressure reducing device mainly includes components such as connecting plate 6, base plate 2, sealing plate 3, guide bolt 4, and spring 5.

[0024] Water outlets, corresponding to the positions of pressure relief ports, are provided in the middle area of ​​both the connecting plate 6 and the base plate 2. These water outlets are rectangular in shape and roughly the same size as the pressure relief ports. Under normal circumstances, the sealing plate 3 will block and seal the water outlets on the base plate 2. When the pressure inside the collector 1 increases, the sealing plate 3 will open the water outlets to drain water and relieve pressure.

[0025] like Figure 2 As shown, the connecting plate 6 is generally placed inside the bomb collector 1 and tightly attached to its inner wall. The water outlet in the middle of the connecting plate 6 is directly opposite the pressure relief port, and its main function is to serve as a connecting base for mounting the base plate 2 to the outer wall of the bomb collector 1. The base plate 2 is tightly attached to the outer wall of the bomb collector 1, and a sealing ring 11 is provided between the base plate 2 and the outer wall of the bomb collector 1 to enhance the sealing performance and prevent water from leaking out of the bomb collector 1.

[0026] Correspondingly, the sealing ring 11 has multiple round holes to facilitate the passage of bolts.

[0027] See Figure 4 Multiple mounting holes are provided on both the connecting plate 6 and the base plate 2. These mounting holes are evenly distributed along the circumference of the water outlet and are threaded holes. The mounting holes on the connecting plate 6 correspond one-to-one with the mounting holes on the base plate 2.

[0028] Correspondingly, multiple round holes are provided around the pressure relief port on the bomb collector 1. The round holes correspond one-to-one with the mounting holes so that bolts can pass through the round holes to connect the connecting plate 6 and the base plate 2 together.

[0029] During installation, the connecting plate 6 is placed inside the ammunition collector 1, and the base plate 2 is placed outside the ammunition collector 1. Then, the bolts are passed through the mounting holes on the base plate 2 and the round holes on the ammunition collector 1, and then threadedly connected to the connecting plate 6, thereby fixing the base plate 2 and the connecting plate 6. At this time, the side wall of the ammunition collector 1 is sandwiched between the connecting plate 6 and the base plate 2, and the pressure reducing device is fixedly installed in this way.

[0030] like Figure 2 As shown, in this embodiment, a washer 7 is provided between the inner wall of the connecting plate 6 and the collector 1. The main function of the washer 7 is to distribute pressure. The shape of the washer 7 is similar to that of the connecting plate 6. Correspondingly, the washer 7 also has multiple circular holes corresponding to the mounting holes on the connecting plate 6, so that bolts can pass through.

[0031] In other embodiments, a sealing ring may be provided between the connecting plate 6 and the inner wall of the ammunition collector 1, and the shape of the sealing ring is consistent with the shape of the connecting plate 6. The sealing ring is made of a flexible material, which can change the rigid contact between the connecting plate 6 and the ammunition collector 1 into a flexible contact, preventing damage to the inner wall of the ammunition collector 1.

[0032] like Figure 5 As shown, an annular sealing portion 201 is formed on the front side of the substrate 2 (i.e., the side near the sealing plate 3) protruding outward along the circumference of the water outlet. The surface of the sealing portion 201 that contacts the sealing plate 3 is flat. Multiple bolt holes are provided on the substrate 2, and the bolt holes are evenly distributed around the circumference of the sealing portion 201.

[0033] See Figure 3 , Figure 4In this embodiment, a guide bolt 4 is installed in each bolt hole. A fastening nut 8 is also provided on the guide bolt 4. The guide bolt 4 passes through the bolt hole, inserting from the back of the substrate 2 (i.e., the side away from the sealing plate 3) to the front of the substrate 2. Then, the fastening nut is tightened, and the substrate 2 is clamped by the head of the guide bolt 4 and the fastening nut 8, thus fixing the guide bolt 4 to the substrate 2. The guide bolt 4 is perpendicular to the substrate 2. The sealing plate 3 and the guide bolt 4 are interlocked, and the guide bolt 4 guides the movement of the sealing plate 3.

[0034] To prevent the head of the guide bolt 4 from interfering with the installation of the substrate 2, a countersunk hole is provided in each bolt hole on the back side of the substrate 2 to bury the head of the guide bolt 4, so that the head of the guide bolt 4 is flush with the back surface of the substrate 2.

[0035] In other embodiments, guide rods, guide columns, etc., may also be used as guides to facilitate the movement of the sealing plate 3.

[0036] like Figure 5 As shown, multiple circular holes corresponding to the guide bolts 4 are also provided on the substrate 2. The guide bolts 4 and the circular holes are interlocked and the two are clearance fit.

[0037] See also Figure 3 , Figure 4 A spring 5 is fitted onto each guide bolt 4, and the spring 5 applies a clamping force to the sealing plate 3, causing the sealing plate 3 to fit tightly against the sealing part 201. Each guide bolt 4 is provided with a limiting block 9 and an adjusting nut 10, located at the end of the guide bolt 4 furthest from the base plate 2. The limiting block 9 is fitted onto the guide bolt 4, and the adjusting nut 10 is threadedly connected to the guide bolt 4. The spring 5 is located between the sealing plate 3 and the limiting block 9. The limiting block 9 limits the movement of the spring 5, and the adjusting nut 10 prevents the limiting block 9 from disengaging from the guide bolt 4 and also adjusts the clamping force applied by the spring 5 to the sealing plate 3.

[0038] By rotating the adjusting nut 10, the position of the limiting block 9 on the guide bolt 4 is changed, thereby adjusting the magnitude of the clamping force applied by the spring 5 to the sealing plate 3.

[0039] In other embodiments, the limiting block 9 may not be provided, and the diameter of the adjusting nut 10 may be larger than the diameter of the spring 5, as long as the adjusting nut 10 can limit the spring 5.

[0040] like Figure 4 As shown, in this embodiment, on the side of the sealing plate 3 away from the substrate 2, each round hole is provided with a countersunk hole, and one end of the spring 5 is embedded in the countersunk hole, which can limit the movement of the spring 5.

[0041] like Figure 6 As shown, in this embodiment, four positioning portions 301 are formed outwardly in the middle region of the sealing plate 3 near the substrate 2. The four positioning portions 301 correspond to the four corners of the water outlet holes on the substrate 2. The surface of the positioning portion 301 that contacts the hole wall of the water outlet hole on the substrate 2 is an inclined surface. As the sealing plate 3 approaches the substrate 2, the inclined surface on the positioning portion 301 can play a guiding role, guiding the sealing plate 3 to accurately fit tightly against the sealing portion 201. The positioning portion 301 plays a positioning role.

[0042] In other embodiments, a sealing ring is also provided between the sealing plate 3 and the sealing part 201 to enhance the sealing performance between them. Specifically, a sealing groove can be formed on the contact surface between the sealing part 201 and the sealing plate 3. This sealing groove can be provided on the sealing part 201 or on the sealing plate 3. The sealing ring is embedded in the sealing groove.

[0043] In other embodiments, the positioning part 301 may be omitted. A ring-shaped sealing block 302 may be formed protruding outwards from the middle region on one side of the substrate 2 (see...). Figure 7 The cross-sectional dimensions of the sealing block 302 gradually decrease towards the direction away from the sealing plate 3, making the shape of the sealing block 302 conical. The maximum cross-sectional dimension of the sealing block 302 is larger than the size of the water outlet hole on the substrate 2, and the minimum cross-sectional dimension is smaller than the size of the water outlet hole on the substrate 2.

[0044] As the sealing plate 3 approaches and gradually presses against the sealing part 201, the inclined surface on the outer side of the sealing block 302 serves two purposes: first, it provides positioning and guidance; second, when the sealing plate 3 is pressed tightly against the sealing part 201, the sealing block 302 will interference fit with the water outlet hole on the substrate 2, blocking the water outlet hole and achieving a sealing effect. This, combined with the sealing ring between the sealing plate 3 and the sealing part 201, provides a double sealing effect. However, this requires the water pressure inside the collector 1 to overcome the pressing force exerted on the sealing plate 3 by multiple springs 5 ​​and the frictional force between the sealing block 302 and the inner wall of the water outlet hole on the substrate 2 before the sealing plate 3 can be forced open, allowing water to drain and the pressure to decrease.

[0045] In operation, when the pressure inside the horizontal bomb collector 1 increases, the water inside the collector 1 will squeeze the sealing plate 3 through the pressure relief port. Once the pressure exceeds the clamping force exerted by the spring 5 on the sealing plate 3, the sealing plate 3 will move away from the base plate 2 under the guidance of the guide bolt 4, opening the water outlet on the base plate 2. At this time, the water inside the collector 1 can flow out, thus relieving pressure. After the pressure relief is completed, the pressure inside the horizontal bomb collector 1 decreases and becomes less than the clamping force exerted by the spring 5 on the sealing plate 3. The sealing plate 3 will then return to its original position under the action of the spring 5, re-blocking the water outlet on the base plate 2 to prevent water from flowing out of the horizontal bomb collector 1. Because multiple springs 5 ​​simultaneously apply clamping force to the circumference of the sealing plate 3, the force on the sealing plate 3 is more even.

[0046] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
