Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of firearms, in particular to a 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 structure for preventing 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 structure for preventing 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 the firing base is also provided with a release lever, wherein the release lever comprises a slide bar, the slide bar is perpendicular to the firing safety, one end of the slide bar is slidably fitted on the firing base, the other end of the slide bar is provided with a positioning arm, the positioning arm extends in the direction of the firing safety, a tenon is provided at the end of the positioning arm, a slot is provided on the firing safety corresponding to the tenon, a return spring is sleeved on the slide bar, and the two ends of the return spring act on the release lever and the firing base respectively;
[0006] When the bolt carrier is in the hang-up position, the bolt carrier contacts 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, an axial sliding groove is provided on the slide bar, and a positioning pin is provided on the transmitter seat. The positioning pin is embedded in the axial sliding groove on the slide bar, and the positioning pin positions the slide bar circumferentially.
[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. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Reference numerals
[0016] In the accompanying drawings, 1 is a bolt frame, 2 is a launcher seat, 3 is a launcher safety, 4 is a release lever, 5 is a return spring, 41 is a slide bar, 42 is a positioning arm, 6 is a firing position, and 7 is a stop position. DETAILED DESCRIPTION
[0017] See also Figure 1-Figure 3 A structure for preventing the misoperation of the safety of a firearm firing mechanism includes a bolt frame 1, a transmitter seat 2, a transmitter safety 3, a release lever 4 and a return spring 5. The transmitter safety, the release lever and the return spring are all installed on the transmitter seat. The release lever 4 includes a slide bar, which is perpendicular to the transmitter safety 3. One end of the slide bar is slidably fitted in a slide hole on the transmitter seat 2. The other end of the slide bar is provided with a positioning arm, which extends toward the transmitter safety 3. The end of the positioning arm is provided with a tenon. A slot is provided on the transmitter safety 3 corresponding to the tenon. The slide bar is sleeved with a return spring 5. The two ends of the return spring 5 act on the release lever 4 (positioning arm) and the transmitter seat 2 respectively. The tenon on the release lever 4 is a right-angled tenon, and the slot on the transmitter safety 3 is a right-angled slot.
[0018] When the bolt frame 1 is in the hook position, the bolt frame 1 contacts the release lever 4, the return spring 5 is compressed by the bolt frame 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; specifically: when the bolt frame 1 stays in the hook position, the release lever 4 is forced to slide backward and separate from the transmitter safety 3, and at this time the transmitter safety 3 can be switched between the "fire" and "stop firing" positions.
[0019] When the transmitter safety is in the firing position and the bolt frame leaves the hanging position, the return spring 5 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] The sliding rod and the transmitter base 2 are circumferentially positioned to limit the rotation of the sliding rod. The circumferential positioning can be achieved by polygonal matching (commonly achieved by matching a rectangular hole with a rectangular rod), or by providing an axial sliding groove (not a through groove) on the sliding rod, and providing a positioning pin on the transmitter base 2, which is embedded in the sliding groove, which not only limits the rotation of the sliding rod, but also limits the travel of the sliding rod.
[0021] 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.
