Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0047] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0048] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0049] In a first aspect, referring to Figures 1 to 3 , this embodiment provides a connection structure, including: a connecting rope 19, a first joint 20, a second joint 21, a sheath 22, and an end joint 23.

[0050] The connecting rope 19 is made of steel wire.

[0051] The first joint 20 is connected to one end of the connecting rope 19 and is used to connect to a sensor.

[0052] The second joint 21 is connected to the other end of the connecting rope 19 and is used to connect to an actuating device.

[0053] The sheath 22 is sleeved outside the connecting rope 19, and the connecting rope 19 slides through the sheath 22.

[0054] The end joint 23 is sleeved on both ends of the sheath 22, and the connecting rope 19 slides through the end joint 23. The outer side wall of the end joint 23 has a positioning groove.

[0055] The sheath 22 guides and directs the sliding of the connecting rope 19. By providing the end joint 23, it prevents wear from increasing due to debris entering between the connecting rope 19 and the sheath 22 from the ends of the sheath 22. Inserting an external device (such as a positioning pin) into the positioning groove can limit the movement of the end joint 23 and the sheath 22.

[0056] In a second aspect, referring to Figures 1 to 3 , this embodiment provides a sensor, including: a body 1, a body joint 2, a protective cover 9, a wire joint 3, a wire rope 17, a pull rod 5, a nut 10, a return spring 16, a first lever 7, and a transmission assembly.

[0057] The body 1 has a receiving cavity.

[0058] The body joint 2 is connected to the body 1 and is used to seal one end of the receiving cavity.

[0059] The protective cover 9 covers the outside of the body joint 2 and is connected to one end of the body 1 by screws; there is a cavity left between the protective cover 9 and the body joint 2.

[0060] The wire joint 3 is connected to the protective cover 9 and is used to seal one end of the protective cover 9.

[0061] One end of the wire rope 17 extends into the cavity after passing through the wire joint 3, and the other end of the wire rope 17 is connected to the first joint.

[0062] The pull rod 5 slides through the receiving cavity and the body joint 2; one end of the pull rod 5 is located in the cavity and is connected to one end of the wire rope 17; the other end of the wire rope 17 is connected to the actuating device.

[0063] The nut 10 is movably arranged in the receiving cavity and is threadedly connected to the pull rod 5.

[0064] The return spring 16 is arranged in the receiving cavity and is used to move the pull rod 5 in the direction of the wire rope 17.

[0065] In a specific implementation scenario, the above-mentioned body 1, body joint 2, protective cover 9, wire joint 3, pull rod 5, and return spring 16 are coaxially arranged.

[0066] The middle part of the first lever 7 is rotatably mounted at a specified position through a first pin shaft 15, and the lower part is in rolling or sliding contact with the circumferential side surface of a cam (not shown in the figure). In a specific implementation scenario, a roller 8 is installed at the lower part of the first lever 7, and the roller 8 is in rolling contact with the circumferential side surface of the cam.

[0067] The transmission assembly is used for drivingly connecting the upper part of the first lever 7 and one end of the pull rod 5, so that when the first lever 7 rotates around the first pin shaft 15, the pull rod 5 can be driven to move horizontally. The transmission assembly includes: a connecting rod 4 and a second lever 6.

[0068] One end of the connecting rod 4 is rotatably connected to the upper part of the first lever 7, and the other end is rotatably connected to one end of the second lever 6.

[0069] The other end of the second lever 6 is rotatably and slidably connected to one end of the pull rod 5 through a second pin shaft, and the middle part of the second lever 6 is rotatably mounted at a specified position through a third pin shaft 14.

[0070] The working principle of the above sensor is as follows:

[0071] During the process of the cam rotating clockwise, the protrusion on the cam squeezes the lower end of the first lever 7 upward, causing the first lever 7 to rotate counterclockwise. Then, through the transmission of the connecting rod 4 and the second lever 6, the pull rod 5 drives the steel wire rope 17 to move a certain distance to the right, so that the actuating device performs corresponding actions to meet the corresponding requirements. As the cam continues to rotate clockwise, the protrusion on the cam separates from the first lever 7. Under the restoring force of the restoring spring 16, the pull rod 5 moves leftward to reset, and drives the first lever 7 to rotate clockwise through the pull rod 5 and the transmission assembly, so that the lower end of the first lever 7 maintains rolling or sliding contact with other positions of the cam.

[0072] The actuating device is configured as follows: when the artillery gun meets the requirements of state 1 (state 1 pointed out in the background art), the manual firing operation is allowed to be effective; when the artillery gun meets the requirements of state 2 (state 2 pointed out in the background art), the electric firing operation is allowed to be effective; otherwise, the manual firing or electric firing operation is invalid; in particular, when the ammunition feeding and conveying device is not in the initial position, the manual firing or electric firing operation is invalid.

[0073] The actuating device can be connected to five independently working above-mentioned sensors, and each sensor is respectively used in cooperation with a cam to meet the corresponding requirements. The five sensors are respectively used to detect whether the ammunition feeding and conveying device is in the initial position, the azimuth firing limit, and the elevation firing limit.

[0074] The sensor can also include a proximity switch 18 and an induction block used in cooperation.

[0075] The proximity switch 18 is installed on the outside of the body 1, and the induction block is installed on the upper part of the first lever 7. When the first lever 7 rotates counterclockwise, the induction block approaches the proximity switch 18, and the proximity switch 18 obtains a proximity signal; when the first lever 7 rotates clockwise, the induction block moves away from the proximity switch 18, and the proximity switch 18 obtains a non-proximity signal. Through the setting of the proximity switch 18 and the induction block, it is convenient to obtain the state information of the artillery gun.

[0076] Combining the above content, the above sensor has at least the following beneficial effects:

[0077] First, the induction of the artillery state is realized by a mechanical structure. Through the settings of the main body 1, steel wire rope 17, pull rod 5, first lever 7, transmission component and return spring 16, the linkage between the execution device and the cam is finally realized.

[0078] It should be noted that the execution device and the cam itself are not the key points of improvement in this application.

[0079] Second, through the cooperation of the nut 10 and the return spring 16, it is convenient to reset the pull rod 5 under the action of the return force of the return spring 16.

[0080] Third, through the setting of the main body joint 2, it is convenient to limit the movement range of the return spring 16 and the nut 10.

[0081] Fourth, through the settings of the wire joint 3 and the protective cover 9, the connection between the steel wire rope 17 and the pull rod 5 is protected (such as dustproof and waterproof).

[0082] Fifth, through the settings of the proximity switch 18 and the induction block, it is convenient to obtain the state information of the artillery.

[0083] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Without conflict, the embodiments of this application and the features in the embodiments can be arbitrarily combined with each other. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
