Description

Technical Field

[0001] The utility model relates to the technical field of firearms, in particular to a rotary structure for preventing misoperation of a safety of a firearm firing mechanism. Background Art

[0002] When a firearm stops firing, the shooter's first reaction is to turn off the safety on the firing mechanism to prevent accidental firing. However, turning off the safety on the firing mechanism does not prevent the bullet from firing again when the fault occurs. If the bullet fires again when the fault is eliminated, the energy of the gunpowder gas will drive the automatic machine to recoil, which may cause impact damage to the firing mechanism and even endanger the shooter's safety. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a rotary structure for preventing the misoperation of the safety of a firearm firing mechanism. The firing mechanism safety can be switched only when the bolt frame is in the on-hook position.

[0004] The purpose of the utility model is achieved in this way:

[0005] A rotary structure for preventing the misoperation of the safety of a firearm firing mechanism, comprising a bolt frame and a firing base, wherein the firing base is provided with a firing safety, and a release lever shaft is fixed to the firing base, wherein the release lever shaft is parallel to the firing safety, and a release lever and a return spring are sleeved on the release lever shaft, wherein the return spring is a torsion spring, and the two ends of the return spring act on the release lever and the firing safety respectively, and a tenon is provided in the middle of the release lever facing the firing safety, and a slot is provided on the firing safety corresponding to the tenon;

[0006] When the bolt carrier is in the on-hook position, the bolt carrier contacts the end of the release lever, the return spring is compressed by the bolt carrier, the tenon on the release lever is separated from the slot on the transmitter safety, and the transmitter safety can change position;

[0007] When the transmitter safety is in the firing position and the bolt carrier leaves the hanging position, the return spring drives the release lever to reset, and the tenon on the release lever engages with the slot on the transmitter safety to limit the switching position of the transmitter safety.

[0008] Preferably, the tenon on the release lever is a right-angled tenon, and the slot on the transmitter safety is a right-angled slot.

[0009] Preferably, a slope is provided at a position where the bolt frame contacts the end of the release rod, and when the bolt frame is located at the hanging position, the slope of the bolt frame fits with the end of the release rod.

[0010] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0011] The utility model realizes that the transmitter safety can be switched only when the bolt frame is in the on-hook position, thereby solving the problem of gun damage and personal injury caused by wrong switching of the transmitter safety when the gun stops firing.

[0015] Reference numerals

[0016] In the accompanying drawings, 1 is the bolt frame, 2 is the launcher seat, 3 is the launcher safety, 4 is the release lever, 5 is the release lever shaft, 6 is the return spring, and 7 is the firing position. DETAILED DESCRIPTION

[0017] See also Figure 1-Figure 3 A rotary structure for preventing the misoperation of the safety of a firearm firing mechanism includes a bolt frame 1, a firing base 2, a firing base 2 is provided with a firing safety 3, a release lever shaft 5 is fixed to the firing base 2, the release lever shaft 5 is parallel to the firing safety 3, a release lever 4 and a return spring 6 are sleeved on the release lever shaft 5, the return spring 6 is a torsion spring, and the two ends of the return spring 6 act on the release lever 4 and the firing safety 3 respectively, a tenon is provided in the middle of the release lever 4 facing the firing safety 3, and a slot is provided on the firing safety 3 corresponding to the tenon. The tenon on the release lever is a right-angle tenon, and the slot on the firing safety is a right-angle slot.

[0018] When the bolt carrier 1 is in the hang-up position, the bolt carrier 1 contacts the end of the release lever 4, the return spring 6 is compressed by the bolt carrier 1, the tenon on the release lever 4 is separated from the slot on the transmitter safety 3, and the transmitter safety 3 can change its position; the portion where the bolt carrier 1 contacts the end of the release lever 4 is provided with an inclined surface, and when the bolt carrier 1 is in the hang-up position, the inclined surface of the bolt carrier 1 is fitted with the end of the release lever 4. Specifically: when the bolt carrier 1 stays in the hang-up position, the release lever 4 is forced to rotate backward and separate from the transmitter safety 3, and at this time, the transmitter safety 3 can be switched between the two positions of "firing" and "stop shooting". After the bolt carrier 1 leaves the hang-up position, the release lever 4 returns to its original position under the action of the return spring 6. Only when the bolt carrier is in the hang-up position, the release lever is forced to rotate, and the tenon on the release lever leaves the slot on the transmitter safety, can the transmitter safety be switched to the "stop shooting" position.

[0019] When the transmitter safety is in the firing position and the bolt frame leaves the hanging position, the return spring 6 drives the release lever 4 to reset, and the tenon on the release lever 4 engages with the slot on the transmitter safety 3 to limit the switching position of the transmitter safety.

[0020] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
