Referring to fig. 1, 2, 3 and 4, the zero second-release rocket connector provided by the utility model at least comprises a first bracket 1 arranged on one radial side of a ground flange 100, a second bracket 2 arranged on one radial side of an arrow flange 200, and a locking mechanism 3 arranged on the first bracket 1. The first bracket 1 provides a supporting installation position for the locking mechanism 3, and the second bracket 2 can be fixedly connected with the first bracket 1 through the locking mechanism 3, so that the butt joint locking of one radial side of the connector is realized. The other radial end of the ground flange 100 is provided with an outward opening, which is matched with the pin shaft 6 arranged at the other radial end of the arrow flange 200. The axial direction of the pin shaft is parallel to the plane where the radial direction of the flange on the arrow is located, and after the opening is in butt joint with the pin shaft, the inner wall of the opening can limit the movement of the pin shaft 6, so that the pin shaft 6 can only be separated from the opening of the opening. For example, the opening may be a semicircular opening 5.

It should be noted that, the semicircular opening 5 is opened in the radial direction of the ground flange 100, and the opening is outward, and only the opening of the semicircular opening 5 is used for abutting and disengaging the pin shaft 6. That is, after the semicircular opening 5 is abutted with the pin shaft 6, no matter how much the semicircular opening 5 rotates along the outer wall of the pin shaft 6, the pin shaft 6 can only be separated from the opening of the semicircular opening 5 in order to separate the semicircular opening 5 from the pin shaft.

Specifically, when the connector is mated, the semicircular opening 5 is mated with the pin shaft 6, and then the ground flange 100 is rotated to be mated with the arrow flange 200 by taking the pin shaft 6 as the shaft, and the semicircular opening 5 and the pin shaft 6 are limited to each other in the axial direction of the arrow flange 200. During rotation of the ground flange 100 about the pin 6, the opening orientation of the semicircular opening 5 is changed from intersecting the plane of the arrow-shaped flange 200 to being parallel thereto. With the ground flange 100 and the on-arrow flange 200 docked in place, the locking mechanism 3 actively or passively dock and lock the first bracket 1 and the second bracket 2, thereby fixedly connecting the ground flange 100 and the on-arrow flange 200. Wherein, the locking mechanism 3 locks and connects one radial side of the connector, and the semicircular opening 5 and the pin shaft 6 are mutually limited in the axial direction of the arrow flange 200 to fix the other radial side of the connector.

When the connector is separated, an unlocking force can be firstly applied to the locking mechanism 3 to release the limit of the second bracket 2, so that the first bracket 1 is disconnected with the second bracket 2. At this time, the semicircular opening 5 and the pin shaft 6 are still limited to each other in the axial direction of the arrow flange 200, and the pin shaft 6 will limit the side where the semicircular opening 5 is located to move away from the arrow flange, so that the connector cannot be completely separated. After the locking mechanism 3 is unlocked, the rotational limit of the connector is also released synchronously. Under the action of gravity of the connector and the inertia force of the unlocking force, the abutting end of the ground flange 100 rotates by a certain angle by taking the pin shaft 6 as an axis, so that after the opening orientation of the semicircular opening 5 is converted from being parallel to the plane where the arrow flange 200 is positioned to be intersected with the plane by a certain angle, the semicircular opening 5 can be smoothly separated from the pin shaft 6, and the complete separation of the connector is realized.

According to the zero second falling rocket connector provided by the embodiment of the utility model, the rotary self-adaptive locking mechanism is adopted, so that dependence on the skills and the number of operators is reduced, the connector can be easily connected by a single person, and the operation is simple and convenient.

Further, the connector of the embodiment of the utility model is fixedly connected through two ends, the first end is matched with the second bracket 2 through the first bracket 1 and the locking mechanism 3 to realize locking fixation, and the second end is matched with the pin shaft 6 through the semicircular opening 5 to realize limiting connection. In order to ensure that the arrow flange 200 and the ground flange 100 can be stably abutted and well sealed at each point of the abutting end surface, the first end and the second end may be symmetrically disposed at two radial sides of the connector. The first bracket 1 and the second bracket 2 may be bent steel plates which are arranged in a matched manner. In order to prevent the support from being deformed under force, the first support 1 can be divided into three parts according to the shape characteristics of the bent steel plate. The first part of the first bracket 1 is connected with the ground flange through a screw 11, the second part is connected with the first part and the third part, and the third part is used for installing and fixing the locking mechanism 3.

The second bracket 2 is correspondingly arranged to be three parts with the first bracket 1, the first part of the second bracket 2 is connected with an arrow-shaped flange through a screw 22, the second part is connected with the first part and the third part, and the third part is used for locking and fixing the locking mechanism 3.

The plane of the first portion of the first bracket 1 is not parallel to the plane of the third portion.

Referring also to fig. 1 and 5, in one embodiment, the locking mechanism 3 includes a spring housing 31, a spring 32, and a lock cylinder 33. The spring housing 31 is a thin-walled housing structure to which the spring 32 and a portion of the lock cylinder 33 are mounted. Wherein, one axial end of the spring shell 31 is fixedly connected with the back of the abutting surface of the first bracket 1 and the second bracket 2, and a first through hole for the lock core 33 to extend is arranged at the other axial end of the spring shell 31. The spring 32 and part of the lock core 33 are arranged inside the spring shell 31, the spring 32 is sleeved on the periphery of the lock core 33, and two ends of the lock core 33 extend out of the spring shell 31. The lock cylinder 33 is a lock execution unit, and an end of the lock cylinder extending from the first through hole is a force application end, and can be used for applying an unlocking force to the lock cylinder 33. The other end of the lock core 33 is a locking end and is used for being matched and locked and fixed with the second bracket 2 after penetrating through the first bracket 1. In order to facilitate the locking end of the lock core 33 to apply a locking force to the second bracket 2, a second through hole for the lock core 33 to penetrate is formed at the abutting position of the first bracket 1 and the spring housing 31, and the lock core 33 extends out of the spring housing 31 and then penetrates through the second through hole of the first bracket 1. The spring 32 can provide continuous locking force for the lock core 33, so that the lock core 33 stretches into the fixing hole 21 of the second bracket 2 and limits the fixing hole under the action of elastic force, and the first bracket 1 and the second bracket 2 are fixedly locked.

In the above embodiment, the spring housing 31 may be mounted to the first bracket 1 by the screw 300 to facilitate replacement and attachment of the spring housing.

In order to increase the connection stability of the ground flange and the arrow flange, the structures of the first bracket and the second bracket can be properly adjusted, and the axial direction of the lock cylinder is prevented from being parallel to the axial direction of the ground flange.

Further, the lock core 33 is axially provided with a boss 331 for pressing and applying force by the spring 32. One end of the spring 32 is connected with the inner wall of the spring housing 31, the other end abuts against the boss 331, and the spring 32 is compressively disposed between the inner wall of the spring housing 31 and the boss 331. The compressed spring 32 releases the elastic force to provide the locking force for the lock cylinder 32, so that the first bracket 1 and the second bracket 2 are locked and fixed. When external force is applied to pull the lock cylinder 33 from the force application end of the lock cylinder 33, the boss compression spring 32 can be driven to deform, a moving space is provided for unlocking action of the lock cylinder 33, the lock cylinder 33 can be quickly separated from the second bracket 2, and locking limit on the second bracket 2 is released.

The diameter of the second through hole is larger than that of the valve core and smaller than the outer diameter of the boss.

With continued reference to fig. 1 and 5, in one embodiment, to facilitate the application of an unlocking force to the spool, a pulling hole 332 for pulling the lock cylinder 33 may be provided at an end (force application end) of the lock cylinder 33 remote from the arrow-top flange 200. The pulling hole 332 is used for installing a pulling wire rope with one end connected to the ground, and the ground end can drive the lock core 33 to perform unlocking action by pulling the wire rope.

Referring to fig. 1, in one embodiment, in order to achieve a seal of the ground flange interface with the on-arrow flange, a seal mechanism 4 is provided where the on-arrow flange 200 interfaces with the ground flange 100.

Referring to fig. 1 and 5 together, further, the sealing mechanism 4 includes a seal groove 41 and a seal ring 42. The ground flange 100 is provided with a seal groove 41 circumferentially at a position for abutting against the arrow flange 200, and the seal ring 42 is at least partially provided in the seal groove 41. After the ground flange 100 is butted with the arrow-shaped flange 200, the sealing ring 41 is pressed and deformed by the ground flange and the arrow-shaped flange to form end face sealing.

Still further, the cross section of the seal groove 41 may be trapezoidal. Wherein, the notch width of the sealing groove 41 is smaller than the groove bottom width.

According to the zero second drop rocket connector provided by the embodiment of the utility model, the sealing groove with the trapezoid cross section is arranged on the sealing end surface of the ground flange, so that the drop of the sealing ring after the connector drops can be prevented, the damage of superfluous matters generated after the drop of the sealing ring to the launching safety can be effectively prevented, and the tightness of the connector and the rocket flange is improved.

In one embodiment, the fixing hole 21 of the second bracket 2 is a tapered hole 212 with an outward opening on one side for being matched with the lock cylinder 33, and a cylindrical hole 211 communicated with the tapered hole 212 on the other side. During rotation of the ground flange 100 about the pin after mating the semicircular opening with the pin, the locking end of the lock cylinder 33 contacts the tapered bore of the second bracket 2 and the spring 32 is compressed. After the lock core 33 adaptively slides into the cylindrical hole in the conical hole, the spring 32 is recovered to an elongation state, and the lock core 33 fixedly locks the first bracket 1 and the second bracket 2, so that the butt locking and sealing of the connector are realized.

Referring to fig. 4, in the above embodiment, the pin 6 is detachably mounted to the arrow-top flange and disposed tangentially to the periphery of the arrow-top flange 200. After the pin shaft 6 penetrates through the arrow flange, the pin shaft 6 can be fixed on the arrow flange by penetrating through the pin shaft 6 through an opening pin.
