Description

Technical Field

[0001] This utility model belongs to the field of live-fire shooting and relates to a live-fire shooting device. Background Technology

[0002] When conducting live-fire target practice at the firing range, the required ammunition needs to be distributed so that a specified number of ammunition can be given to the shooters to ensure ammunition supply during the target practice.

[0003] For example, patent (CN215572499U) discloses a live-fire ammunition box, which describes that "it includes a box body, a confirmation button on the surface of the box body, an opening for inserting bullets at the top of the box body, a gravity sensor at the bottom of the box body, and a microcontroller inside the box body; the microcontroller includes a memory and a comparator, the memory and the comparator are connected; the confirmation button is connected to the microcontroller, and the microcontroller is connected to the gravity sensor. In this invention, the confirmation button is pressed first, and a bullet is placed into the ammunition box. The gravity sensor measures the weight of the bullet, and the comparator compares the weight data of a single bullet with the pre-stored bullet weight in the memory to determine the type of bullet inserted and to facilitate subsequent counting; after placing the bullet into the ammunition box, the gravity sensor measures the weight of the bullet, and the microcontroller calculates the total weight data of the bullets received with the weight data of a single bullet to obtain the number of bullets loaded in the ammunition box this time."

[0004] The existing technology has the following technical defects: During operation, the existing technology can only count the number of ammunition and cannot participate in the subsequent ammunition distribution process. For some users, the distributed ammunition clips are arranged in different positions, making the clip replacement process relatively slow and affecting the user experience. In addition, for novices, the ejected cartridge cases will fall at their feet and are easily stepped on during the subsequent clip replacement process, which may cause the shooter's body to tilt, posing a certain safety hazard. Utility Model Content

[0005] The technical problem this invention aims to solve is that, for some users, the distributed ammunition clips are arranged in different positions, making the clip changing process slow and affecting the user experience. Furthermore, for beginners, ejected cartridge cases often fall near their feet, easily causing them to be stepped on during subsequent clip changes, potentially leading to the shooter tilting and posing a safety hazard. To overcome the shortcomings of existing technology, this invention provides a live-fire firing device.

[0006] This utility model includes a firing box, on which a firing assembly is installed. The firing assembly includes a pushing cavity. The pushing cavity is located at the upper part of the interior of the firing box. A rotating hole is located at one end of the firing box, and a closing plate is installed inside the rotating hole via a pin. A spring is installed at the end of the pushing cavity away from the closing plate. A limiting plate is fixedly connected to the end of the spring near the closing plate. A toggle block is fixedly connected to the vertical structural surface of the limiting plate near the closing plate. A pushing hole is located on the vertical structural surface of the closing plate in the firing box. The end of the toggle block extends outward through the pushing hole. A pop-out hole is formed through the top end face of the inner wall of the pushing cavity near the closing plate, and elastic rotating plates are symmetrically installed inside the pop-out hole. An installation cavity is located at the bottom end face of the inner wall of the pushing cavity, directly below the pop-out hole. Electric push rods are symmetrically installed inside the installation cavity. A push plate is fixedly connected to the top of the telescopic end of the electric push rod. A support assembly is installed on the firing box.

[0007] Preferably, the support assembly includes a placement cavity, and the side of the ammunition box away from the closing plate has a sunken placement cavity. A telescopic rod is installed on the vertical structural surface of the placement cavity. A fixed shaft is fixedly connected to the telescopic end of the telescopic rod. A first lifting sleeve is sleeved on the top end of the fixed shaft. A bracket is fixedly connected to the top end of the first lifting sleeve. A second lifting sleeve is sleeved on the bottom end of the fixed shaft. A fixed seat is fixedly connected to the bottom of the second lifting sleeve, and support frames are installed on both sides of the fixed seat.

[0008] Preferably, the fixed shaft has threads on both the upper and lower ends of its shaft body. Rotating rings are fitted on the outside of the fixed shaft section at the upper and lower positions of the telescopic rod extension end. The rotating rings are fitted onto the threaded shaft body of the fixed shaft through threaded holes. A rotating groove is formed on the top of the rotating ring above the telescopic rod, and a rotating groove is also formed on the bottom of the rotating ring below the telescopic rod. Rotating sliders are provided inside the grooves. The rotating slider near the first lifting sleeve is fixedly connected to the bottom end face of the first lifting sleeve, and the rotating slider near the second lifting sleeve is fixedly connected to the top end face of the second lifting sleeve.

[0009] Preferably, when the height of the second lifting sleeve from the telescopic rod is at its minimum, the horizontal plane where the bottom end face of the support frame is located is higher than the horizontal plane where the bottom end face of the inner wall of the placement cavity is located. When the telescopic rod is not in operation, the support frame can be completely retracted into the opening space of the placement cavity.

[0010] Preferably, a limiting track is installed at the top end of the ammunition box away from the elastic rotating plate. A convex groove is formed at the top of the limiting track, and a convex slider is provided inside the convex groove. A collection box is fixed to the top of the convex slider. A counter is installed on the inner wall of the receiving cavity of the collection box. A small roller is installed on the fixed block on the bottom end face of the collection box away from the limiting track by a pin. The bottom of the small roller is in contact with the top of the ammunition box.

[0011] Preferably, a baffle is bolted to the vertical structural surface of the firing box near the elastic rotating plate. The length of the baffle is the same as the opening length of the ejection hole. When the baffle is not in operation, the baffle can be folded and placed.

[0012] Working process or working principle:

[0013] Open the closing plate and apply a force towards the spring to the actuating block. Push the collection box to the appropriate position and flip the baffle to a vertical position. When setting up the gun, depending on the gun model, the support assembly can be pulled out of the placement cavity by extending the telescopic rod. First, apply a rotational force to the rotating ring at the bottom of the telescopic rod so that the bottom of the support frame is supported on the ground or firing table. Then, apply a rotational force to the rotating ring above the telescopic rod so that the first lifting sleeve drives the bracket upward to the appropriate position, facilitating the gun setup and ensuring the stability of the gun during firing. During firing, the magazine will fall into the receiving cavity of the collection box. As a sufficient number of spent cartridge cases fall into the collection box, the electric push rod will operate, pushing the push plate upward quickly, so that the magazine loaded with ammunition is ejected through the ejection hole. With the cooperation of the baffle, the magazine falls within the predetermined range, realizing rapid magazine supply, reducing the time spent picking up magazines in different positions, and improving magazine replacement efficiency.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By coordinating the operation of the ammunition delivery components, the ammunition clips can be delivered in a timely manner, allowing them to be retrieved from the same location. This reduces the time spent retrieving ammunition clips from different locations and improves the efficiency of ammunition clip replacement.

[0016] By cooperating with the support components, the system provides support for different types of guns during firing, ensuring the stability of the guns during firing and achieving the integrated effect of ammunition dispensing and stable support. Attached Figure Description

[0023] Example 1

[0024] like Figures 1-3As shown, a live-fire firing device includes a firing box 1, on which a firing assembly is mounted. The firing assembly includes a pushing cavity 2. The pushing cavity 2 is located slightly above the interior of the firing box 1. A rotating hole is located at one end of the firing box 1, and a closing plate 3 is mounted inside the rotating hole via a pin. A spring 4 is mounted inside the pushing cavity 2 at the end away from the closing plate 3. A limiting plate 5 is fixedly connected to the end of the spring 4 near the closing plate 3. A toggle block 6 is fixedly connected to the vertical structural surface of the limiting plate 5 near the closing plate 3. The cartridge box 1 has a push hole 7 on the vertical structural surface of the closing plate 3. The end of the actuating block 6 extends outward through the push hole 7. The push cavity 2 has a pop-out hole on the top end face of the inner wall near the closing plate 3. The pop-out hole is symmetrically installed with elastic rotating plates 11 inside. The bottom end face of the inner wall of the push cavity 2 is located directly below the pop-out hole and has an installation cavity 8. The installation cavity 8 is symmetrically installed with electric push rods 9. The top of the telescopic end of the electric push rod 9 is fixed with a push plate 10. The cartridge box 1 is equipped with a support assembly. Opening the closing plate 3 allows the magazine loaded with ammunition to be easily fed into the push cavity 2. When the spring 4 is not in operation, it does not deform. At this time, the limiting plate 5 is closest to the closing plate 3. The vertical cross-sectional dimension of the limiting plate 5 is the same as that of the push cavity 2. When multiple magazines are placed inside the push cavity 2, the spring 4 is compressed and generates a reaction force. The reaction force can ensure the automatic positioning of the magazine at the top of the push plate 10, ensuring the continuity of magazine ejection. When loading ammunition, the limiting plate 5 can be moved towards the spring 4 by applying a pushing force to the actuating block 6, thereby achieving the effect of assisting in loading magazines. When the electric push rod 9 is in operation, the push plate 10 can be quickly pushed out and retracted into the mounting cavity 8.

[0025] A limiting track 13 is installed at the top of the ammunition box 1, away from the elastic rotating plate 11. A convex groove is formed at the top of the limiting track 13, and a convex slider 14 is installed inside the groove. A collection box 15 is fixed to the top of the slider 14. A counter is installed on the inner wall of the receiving cavity of the collection box 15. A small roller 16 is mounted on a fixed block on the bottom end face of the collection box 15, away from the limiting track 13, via a pin. The bottom of the small roller 16 contacts the top of the ammunition box 1. A control device is installed on the counter, which can drive an electric push rod 9. Before firing the gun, a pushing force is applied to the collection box 15 according to the ejection position of the spent cartridge case. The small roller 16 rotates, and the convex slider 14 moves along the convex groove, causing the collection box 15 to move along the limiting track 13 to a suitable position, ensuring that the dropped spent cartridge case can enter the receiving cavity of the collection box 15.

[0026] A baffle 12 is bolted to the vertical structural surface of the magazine box 1 near the elastic rotating plate 11. The length of the baffle 12 is the same as the opening length of the ejection hole. When the baffle 12 is not in use, the plate can be folded. The maximum rotation angle of the baffle 12 is 90°. When the baffle 12 is rotated to the vertical position, it can prevent the magazine from falling during ejection.

[0027] During operation, the structural design of the ammunition firing assembly opens the closing plate 3 and applies a force towards the spring 4 to the actuating block 6, pushing the collection box 15 to the appropriate position and flipping the baffle 12 to a vertical position. During firing, the magazine falls into the receiving cavity of the collection box 15. As a sufficient number of spent cartridge cases fall into the collection box 15, the electric push rod 9 will operate, pushing the push plate 10 to move upward quickly, causing the magazine containing ammunition to be ejected through the ejection hole. With the cooperation of the baffle 12, the magazine falls within a predetermined range, achieving rapid magazine supply, reducing the time spent picking up magazines from different positions, and improving magazine replacement efficiency.

[0028] Example 2

[0029] like Figure 2 , Figures 4-5 As shown, the support assembly includes a placement cavity 17. A sunken placement cavity 17 is formed on the side of the ammunition box 1 away from the closing plate 3. A telescopic rod 18 is mounted on the vertical structural surface of the placement cavity 17. A fixed shaft 19 is fixedly connected to the telescopic end of the telescopic rod 18. A first lifting sleeve 20 is fitted onto the top of the fixed shaft 19. A bracket 21 is fixedly connected to the top of the first lifting sleeve 20. A second lifting sleeve 22 is fitted onto the bottom of the fixed shaft 19. A fixed seat is fixedly connected to the bottom of the second lifting sleeve 22, and support frames 23 are mounted on both sides of the fixed seat. The support frames 23 are bolted to the fixed seat at the bottom of the second lifting sleeve 22. The bracket 21 is V-shaped to accommodate gun bodies of different sizes.

[0030] The fixed shaft 19 has threads on both the upper and lower ends of its shaft body. Rotating rings 24 are fitted on the outside of the fixed shaft 19 at the upper and lower positions of the telescopic end of the telescopic rod 18. The rotating rings 24 are fitted onto the threaded shaft body of the fixed shaft 19 through threaded holes. The top of the rotating rings 24 above the telescopic rod 18 has a rotating groove, and the bottom of the rotating rings 24 below the telescopic rod 18 also has a rotating groove. Rotating sliders are provided inside the grooves. The rotating sliders near the first lifting sleeve 20 are fixedly connected to the bottom end face of the first lifting sleeve 20, and the rotating sliders near the second lifting sleeve 22 are fixedly connected to the top end face of the second lifting sleeve 22. The internal cross-sectional dimension of the first lifting sleeve 20 is larger than that of the fixed shaft 19. The horizontal cross-sectional dimension of the second lifting sleeve 22 is the same as that of the first lifting sleeve 20. By rotating the rotating ring 24 above the telescopic rod 18, the first lifting sleeve 20 rotates along the thread on the fixed shaft 19, causing the bracket 21 to move upward along the fixed shaft 19. By rotating the rotating ring 24 below the telescopic rod 18, the second lifting sleeve 22 drives the support frame 23 to move downward along the fixed shaft 19.

[0031] When the second lifting sleeve 22 is at its lowest height from the telescopic rod 18, the horizontal plane where the bottom end face of the support frame 23 is located is higher than the horizontal plane where the bottom end face of the inner wall of the placement cavity 17 is located. When the telescopic rod 18 is not in operation, the support frame 23 can be completely retracted into the opening space of the placement cavity 17.

[0032] During operation, thanks to the structural design of the support assembly, when setting up the firearm, depending on the firearm model, the support assembly can be pulled out of the placement cavity 17 by extending the telescopic rod 18. First, a rotational force is applied to the rotating ring 24 at the bottom of the telescopic rod 18, so that the bottom of the support frame 23 is supported on the ground or firing table. Then, a rotational force is applied to the rotating ring 24 above the telescopic rod 18, so that the first lifting sleeve 20 drives the bracket 21 to move upward to a suitable position, facilitating the setting up of the firearm and ensuring the stability of the firearm during firing.

[0033] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
