Detailed Description

The invention is described in detail below by way of example with reference to the accompanying drawings.

Example 1:

the embodiment provides a mechanical unlocking automatic trigger device, can realize the automatic triggering of the gun of insurance and trigger switch class such as high-pressure squirt/oil gun, the action is reliable.

This automatic trigger device is applicable to the firearms of taking insurance and trigger switch, includes: the safety device comprises a safety release mechanism and a firing mechanism, wherein the safety release mechanism is used for opening the safety of the firearm so as to release the safety; the firing mechanism is used for pushing a firing switch of the firearm to complete firing.

Taking the water gun/oil gun as an example, the automatic trigger device is provided with a sleeve for clamping the water gun/oil gun, after the water gun/oil gun is clamped, the safety release mechanism corresponds to the position of a safety pusher dog 1 on the water gun/oil gun, and the trigger mechanism corresponds to the position of a trigger switch on the water gun/oil gun.

As shown in fig. 1 and 2, the safety release mechanism includes: the rotary electromagnet 7 is installed on the bottom plate 10 through the electromagnet support 6, and a swing rod of the rotary electromagnet 7 is connected with the safety pusher dog 1 on the firearm and used for driving the safety pusher dog 1 to rotate 90 degrees. Initially, the safety pusher dog 1 is in a locking position, and a trigger switch is locked, so that the trigger switch cannot perform trigger action; when forward current is conducted to the rotary electromagnet 7, the rotary electromagnet 7 drives the safety pusher dog 1 to rotate 90 degrees, the safety pusher dog 1 unlocks the trigger switch, and the safety pusher dog 1 is in an unlocking position at the moment; when reverse current is applied to the rotary electromagnet 7, the rotary electromagnet 7 drives the safety pusher dog 1 to rotate reversely by 90 degrees and return to the locking position.

The firing mechanism includes: the linear direct-acting electromagnet 8, the firing shaft 12 and the switch trigger plate 2 are arranged on the bottom plate 10 through a support, a sliding rod (the sliding rod is a part used for connecting a load in the linear direct-acting electromagnet) of the linear direct-acting electromagnet 8 is connected with the intermediate shaft 5 through a connecting plate 11, the axis of the intermediate shaft 5 is parallel to that of the sliding rod, and when the sliding rod of the linear direct-acting electromagnet 8 moves linearly, the intermediate shaft 5 can be driven to move linearly along the axis. One end of the intermediate shaft 5 is fixedly connected to the connecting plate 11, the other end of the intermediate shaft extends into the guide sleeve 9 and is in sliding fit with the guide sleeve 9, and the guide sleeve 9 is fixed on the bottom plate 10. The trigger shaft 12 is a stepped shaft, one end of the trigger shaft is positioned inside the guide sleeve 9, and the other end of the trigger shaft extends out of the guide sleeve 9 and then is connected with the switch trigger plate 2. The firing shaft 12 and the middle shaft 5 are coaxially arranged, the diameter smaller end of the firing shaft 12 is opposite to the middle shaft 5, a gap is reserved between opposite surfaces, and the diameter smaller end of the firing shaft 12 is fixedly connected with a blocking piece. The outer circumference of the section of the percussion shaft 12 with smaller diameter is sleeved with a spring 4, one end of the spring 4 is abutted against the blocking piece, and the other end is abutted against an annular bulge arranged on the inner circumference of the guide sleeve 9. Taking the direction shown in fig. 1 as an example, when the linear direct-acting electromagnet 8 is energized to move the slide bar leftward, the intermediate shaft 5 is driven to move leftward, the intermediate shaft pushes the trigger shaft 12 to move leftward, and the trigger plate 2 at the end of the trigger shaft 12 pushes the trigger switch to complete triggering, as shown in fig. 3. Meanwhile, in the process that the firing shaft 12 moves leftwards, the spring 4 is compressed, and after the linear direct-acting electromagnet 8 is powered off, the firing shaft 12 automatically returns under the action of the restoring force of the spring 4.

Example 2:

on the basis of the embodiment 1, as the positions of the safety and the trigger switch are close, the space for accommodating the switch trigger plate 2 is smaller, so that when the safety pusher dog 1 rotates, the safety pusher dog can interfere with the switch trigger plate 2, and based on the interference, when the safety pusher dog is at the initial position, the switch trigger plate 2 deviates from the trigger position (the position for pushing the trigger switch through linear motion) by a certain angle, so as to ensure that the safety pusher dog 1 can smoothly rotate to complete the relief of the safety; after the safety is relieved, the switch trigger plate 2 is rotated to a triggering position.

In order to make the structure of the automatic trigger device simple, the switch trigger plate 2 rotates to the right position and the firing shaft 12 moves linearly synchronously, namely the firing shaft 12 rotates a set angle while moving linearly, so that the switch trigger plate 2 rotates to the right position. Based on this, a rotation mechanism is provided, the rotation mechanism including: the guide pin is arranged on the firing shaft 12, the rotating groove 13 is arranged on the guide sleeve 9 and matched with the guide pin 3, as shown in fig. 1, the rotating groove 13 with a set deflection angle is processed on the circumferential surface of the guide sleeve 9, the rotating groove 13 comprises a groove A parallel to the axis of the firing shaft 12 and a groove B which has a certain bending angle with the groove A, the groove A and the groove B are in transition through an arc section, one end of the guide pin 3 is fixed on the firing shaft 12, and the other end of the guide pin is positioned in the rotating groove 13. Initially, the guide pin 3 is located at the end of the groove B, and when the trigger shaft 12 moves linearly along the axis of the trigger shaft, the guide pin 3 moves along the track of the rotary groove 13 in the rotary groove 13, and the rotary groove 13 has a certain bending angle, so that the trigger shaft 12 can be driven to rotate by a certain angle, and the switch trigger plate 2 is driven to rotate by a certain angle. Meanwhile, the groove A in the rotating groove 13 can play a limiting role in the linear motion stroke of the firing shaft 12.

Therefore, initially, the switch trigger plate 2 deviates from the trigger position by a set angle, and when the automatic trigger device works, firstly, the safety release mechanism acts to enable the safety pusher dog 1 to rotate by 90 degrees and release the safety; then the firing mechanism acts to enable the firing shaft 12 to move linearly towards the firing switch, in the process of the linear motion of the firing shaft 12, under the matching of the guide pin 3 and the rotary groove 13, the firing shaft 12 drives the switch trigger plate 2 to rotate for a set angle, so that the switch trigger plate 2 rotates to a firing position before touching the firing switch, and then the firing shaft 12 continues to drive the switch trigger plate 2 to move to push the firing switch, thereby completing firing.

Example 3:

on the basis of the above embodiment 1 or embodiment 2, in order to ensure the reliability of the automatic triggering device, two sets of mutually independent automatic triggering devices are arranged on the same bottom plate 10, and the two sets of automatic triggering devices are arranged in parallel up and down and are respectively used as main backups.

In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
