Description

Technical Field

[0001] The invention relates to a latch opening handle structure for a recoilless gun, which is a latch opening and closing operating component and a locking and limiting structure of the recoilless gun and can be used on a recoilless gun launching device. Background Art

[0002] During recoilless rifle bolt operation, the locking ring and the wedge-shaped projection on the breech block lock together. However, due to the beveled fit of the locking ring and the breech block, repeated use can wear the ring and breech block, preventing them from locking. Therefore, a forced locking mechanism is required. Furthermore, the traditional design of the recoilless rifle bolt handle is fixed to the bolt body and cannot be folded. During jungle marches and battles, it can easily become tangled with debris, hindering soldiers' use and delaying combat opportunities.

[0003] Therefore, in view of the above situation, a bolt handle structure for a recoilless gun is designed. Summary of the Invention

[0004] The object of the present invention is to provide a bolt handle structure for a recoilless gun.

[0007] A further improvement of the technical solution of the present invention is that a protective cover is further provided, which is located above the locking ring and corresponds to the position of the deflection rod and the deflection rod shaft.

[0008] A further improvement of the technical solution of the present invention is that the limit block includes an integrally formed vertical clamping column and a control column arranged laterally to cooperate with the end of the bias rod; the end of the bias rod is located at the lower end of the control column.

[0009] A further improvement of the technical solution of the present invention is that a hook-shaped structure located at the lower end of the control column is integrally provided at the end of the deflection rod.

[0010] A further improvement of the technical solution of the present invention is that a long through slot is provided on the side wall of the limit seat to enable the control column to move up and down.

[0011] Due to the adoption of the above technical solution, the technical effects achieved by the present invention are as follows:

[0012] The unlocking handle mechanism of the present invention is provided with a folding structure and a forced locking structure, which not only can achieve folding, thereby improving the handling performance of the weapon and the rapid response ability of soldiers when marching and fighting in the jungle, but also can solve the problem of the locking ring being loosened due to wear, thereby improving the reliability and safety of the weapon.

[0021] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; it may refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0022] The invention relates to a latch handle structure for a recoilless gun. The latch handle is used on the recoilless gun and can be folded and opened when in use.

[0023] like Figure 1 、 Figure 2 As shown, the structure mainly includes a folding structure and a forced locking structure. The folding mechanism folds the handle toward the gun body, reducing space usage. The folding mechanism includes a handle 13 and a connecting seat 8 fixedly connected to the locking ring 1. The folding mechanism also includes a folding interface provided on the locking ring 1 and a clamping shaft 9 inserted into the connecting seat 3. The connecting seat 8 is fixedly connected to the locking ring 1, which is mounted on the gun body and can rotate about its axis. The handle 13 is hingedly connected to the connecting seat 8 via a rotating shaft 11. A groove is provided on one side of the handle 13 for mounting the grip 12.

[0024] like Figure 3 As shown, a positioning keyway is provided on the connecting base 3 corresponding to the card shaft 9 to control the upright and folded positions of the locking handle 13. The card shaft 9 is used to control the locking and release between the connecting base 8 and the locking ring 1. After the connecting base 8 and the locking ring 1 are released, the handle 13 can be upright. Two card slots are provided on the card shaft 9, forming a card block between the two slots. When the card block on the card shaft 9 corresponds to the positioning keyway on the connecting base 3, the lock between the connecting base 8 and the locking ring 1 can be released, thereby folding and unfolding the handle. A spring is provided at the inner end of the card shaft 9 to return the card shaft 9 to its original position.

[0025] like Figure 1 、 Figure 2 As shown, the forced locking mechanism of the present invention includes a handle 12, a deflecting rod 6, a stopper 3, and a stopper 2. The handle 12 is hingedly mounted within a groove of a handle 13 using a handle shaft 11; the handle 12 can be concealed within the groove of the handle 13. The handle 12 controls the movement of the deflecting rod 5, which in turn controls the movement of the stopper 2.

[0026] like Figure 2 、 Figure 4As shown, the deflection rod 5 is hinged to the connecting seat 8 using a deflection rod shaft 6. The deflection rod 5 can be rotated in a lever-like manner with the deflection rod shaft 6 as the axis. The end of the deflection rod 5 is arranged corresponding to the limit block 2 and can control the lifting of the limit block 2. The limit block 2 is arranged in the limit seat 3, and a return spring 4 is fixedly arranged at the upper end of the limit block 2. The return spring 4 can drive the limit block 2 to return. The lower end of the limit block 2 cooperates with the locking block fixedly arranged on the gun body to unlock the locking ring 1.

[0027] like Figure 2 As shown, the end of the handle 12 is docked with the bias rod 5 for controlling the lever action of the bias rod 5. A hook structure is integrally provided at the end of the bias rod 5 so that the hook structure drives the limit block 2 to move upward.

[0028] The limiting seat 3 is fixedly connected to the connecting seat 8. A through hole is provided at the center of the limiting seat 3. The limiting block 2 is provided in the through hole of the limiting seat 3 and moves up and down in the through hole.

[0029] In the specific implementation of the present invention, a protective cover 7 is also provided. Figure 2 As shown, the protective cover 7 is located above the locking ring 1 and corresponds to the position of the bias rod 5 and the bias rod shaft 6 to protect the connection part.

[0030] like Figure 2 、 Figure 4 As shown, the limit block 2 includes an integrally formed vertical locking column and a control column disposed transversely and cooperating with the end of the deflection rod 5. The lower end of the vertical locking column is used to lock the locking ring 1, and the transverse control column is used to cooperate with the actuating end of the deflection rod 5. The actuating end of the deflection rod 5 is located at the lower end of the control column. Furthermore, a hook-shaped structure integrally formed at the end of the deflection rod 5 is located at the lower end of the control column.

[0031] like Figure 3 As shown, a long through slot is provided on the side wall of the limiting seat 3 so that the control column is located in the through slot and moves up and down in the through slot.

[0032] When closing the bolt, the stopper 2 moves upward due to the wedge-shaped protrusion on the breech block. Once the bolt is in place, the stopper 2 moves downward under the action of the spring, locking the locking ring 1 and achieving locking. To unlock the bolt, the handle 13 is in an upright position. Pressing the grip 12 in conjunction with the stopper 2 unlocks the bolt, achieving unlocking. When the handle 13 is in a down position, the locking ring 1 cannot be unlocked.

[0033] Furthermore, specifically, when closing the latch, fold the latch body upwards to make it flush with the breech, rotate the locking ring 1 clockwise, so that the limit block 2 slides with the wedge-shaped protrusion on the breech and automatically lifts up. When the latch is in place, the limit block 2 is reset under the action of the return spring 4, and the wedge-shaped protrusion on the breech is locked, thus realizing the forced locking limit function of the latch. At this time, press the card shaft 9 into place, and the connecting seat 8 and the locking ring 1 are released from their positions. Rotate the handle 13 forward into place, and the card shaft 9 is reset under the action of the spring force, locking the connecting seat 8 and the locking ring 1 to achieve folding. When unlatching, first open the folding structure, hold the handle 13 with your right hand, and naturally press the grip 12 with your palm. The grip 12 will press down one end of the deflection rod 5, and the limit block 2 will move upward through the lever principle to release the lock. Rotate the locking ring 1 counterclockwise to complete the unlatching.

[0034] The latch handle mechanism can not only be folded, improving the handling performance of the weapon and the soldiers' quick response ability when marching and fighting in the jungle, but also solves the problem of the locking ring being loosened due to wear, thereby improving the reliability and safety of the weapon.

[0035] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
