Therefore, the reliability of the mechanism for realizing the quick opening and closing of the hatch door is crucial. Moreover, since special vehicle-mounted equipment is used in extremely complex climates and harsh geographical environment areas with high cold, high temperature, and high humidity at the border for a long time, it is required that the mechanism is simple and convenient to disassemble, assemble, and repair, resistant to high and low temperatures, corrosion-resistant, and meets the requirements for long-term use in complex climates and geographical environments. It needs to have a self-locking function to ensure that it cannot be automatically unlatched and opened due to non-human operation factors such as vibration during operation, to ensure the safety performance of the system, and it also needs to be able to open and lock in the shortest time to achieve quick locking and quick opening, so as not to delay the fighter plane and cause irreversible consequences. Therefore, there is an urgent need to develop a safety mechanism device that is urgently lacking on the hatch doors of special vehicle-mounted equipment to meet the quick opening and closing response function of the equipment hatch door. Utility Model Content

[0003] To solve the above problems, the purpose of the present utility model is to provide a new type of vehicle-mounted quick-lock and quick-open safety mechanism device to meet the requirements for long-term use in climate and geographical environments and the quick opening and closing response function of the equipment hatch door.

[0004] The purpose of the present utility model is achieved through the following technical solutions:

[0005] A new type of vehicle-mounted quick-lock and quick-open safety mechanism device is used for locking or opening between two opening and closing components, namely a door panel and a door frame, and includes a lock base, a swivel arm base, a clamping seat, a rotating lock arm, and a lock-loosening prevention fastener; the lock base is installed on one of the opening and closing components, the swivel arm base and the clamping seat are installed on the other opening and closing component, the lock base and the clamping seat are respectively located on both sides of the swivel arm base, a lock groove is provided on the lock base, and a clamping groove is provided on the clamping seat; the rotating lock arm is rotatably installed on the swivel arm base through a cylindrical pin and can rotate back and forth around the cylindrical pin and alternately engage into the lock groove and the clamping groove; the lock-loosening prevention fastener is installed on the rotating lock arm and can lock the rotating lock arm on the lock base or the clamping seat; when the rotating lock arm engages into the lock groove and is locked by the lock-loosening prevention fastener, the door panel and the door frame are locked; when the rotating lock arm engages into the clamping groove, the door panel and the door frame are opened.

[0006] More preferably, the lock base is installed on the door frame, and the swivel arm base and the clamping seat are installed on the door panel.

[0007] More preferably, for the convenience of operation, when the rotating lock arm engages into the lock groove and is locked by the lock-loosening prevention fastener, the lock base is located between the lock-loosening prevention fastener and the rotating lock arm; when the rotating lock arm engages into the clamping groove, the clamping seat is located between the lock-loosening prevention fastener and the rotating lock arm.

[0008] Furthermore, in order to make the anti-loosening fastener lock the rotating lock arm on the lock seat more stably, the side of the anti-loosening fastener facing the lock seat and the side of the lock seat facing the anti-loosening fastener are matched with each other by a convex spherical surface and a concave spherical surface.

[0009] Furthermore, to enhance the anti-loosening effect, the anti-loosening fastener includes a knurled ball head locking nut, a flange nut and a circlip; the knurled ball head locking nut and the flange nut are threadedly connected to the rotating lock arm, the circlip is stuck on the part of the rotating lock arm away from the lock seat, the flange nut is located between the knurled ball head locking nut and the circlip, and at the same time the ball head of the knurled ball head locking nut faces the lock seat, and correspondingly, a spherical surface groove matching the ball head of the knurled ball head locking nut is provided on the side of the lock seat facing the anti-loosening fastener.

[0010] Furthermore, the diameters of the spherical surface groove and the ball head of the knurled ball head locking nut are larger than the diameter of the rotating lock arm and the width of the lock groove, so that the rotating lock arm can only leave the card slot after the ball head of the knurled ball head locking nut completely leaves the spherical surface groove, ensuring effective locking.

[0011] Furthermore, both the knurled ball head locking nut and the flange nut adopt fine-pitch left-hand threads and are matched with medium engagement accuracy. During the operation vibration process, the characteristics of the left-hand threads are fully utilized to ensure that the locking state becomes tighter and tighter, which can effectively prevent automatic unlocking and opening and meet the self-locking function.

[0012] Furthermore, the lock seat, the rotating arm seat, the card seat, the rotating lock arm and the anti-loosening fastener are all made of S304 stainless steel, which can be durable, economical and practical under corrosive, high and low temperature working conditions.

[0013] Furthermore, two installation channels are provided inside the card seat, and both ends of each installation channel communicate with the outside of the card seat and the card slot; an elastic clamping mechanism is arranged in each installation channel, and each elastic clamping mechanism includes a set screw, a compression spring and a steel ball; the set screw is threadedly connected to the end of the installation channel away from the card slot from the outside of the card seat; the steel ball is movably arranged in the end of the installation channel close to the card slot and a part of it extends into the card slot. When an external force presses the steel ball, the steel ball will shrink into the installation channel, and after removing the external force, it will return to its original position under the action of the compression spring; the compression spring is arranged in the installation channel between the set screw and the steel ball, and its two ends are respectively connected to the set screw and the steel ball.

[0014] Furthermore, the distance between the steel balls of the two elastic clamping mechanisms on both sides of the card slot is less than the diameter of the rotating lock arm to ensure that the rotating lock arm is restricted in the card slot, so that when the cabin door is opened, the rotating lock arm will not fall off during the operation of the equipment and affect the opening and closing of the door.

[0015] The beneficial effects of the present utility model are as follows:

[0027] As Figure 1 shown, this embodiment provides a new type of vehicle-mounted quick-lock and quick-release safety mechanism device for locking or unlocking between two opening and closing components, namely the door panel and the door frame, including a lock base 1, a swivel arm base 3, a clamping seat 5, a rotating lock arm 2, and a lock-loosening prevention fastener. The lock base 1, the swivel arm base 3, the clamping seat 5, the rotating lock arm 2, and the lock-loosening prevention fastener are all made of S304 stainless steel material, and can be durable, economical and practical under corrosion, high and low temperature working conditions.

[0028] The lock base 1 is installed on the door frame, the swivel arm base 3 and the clamping seat 5 are installed on the door panel. The lock base 1 and the clamping seat 5 are respectively located on both sides of the swivel arm base (the three are connected to form a right triangle, and the swivel arm base 3 is located at the right angle of the right triangle). A lock groove 12 is provided on the lock base 1, and a clamping groove 13 is provided on the clamping seat 5 (in the position state shown Figure 1 the lock base 1 is located above the swivel arm base 3, the clamping seat 5 is located on the right side of the swivel arm base 3, the lock groove 12 is a groove formed by the right-side inner concave of the lock base 1, and the clamping groove 13 is a groove formed by the upper-side inner concave of the clamping seat 5); a groove for installing the rotating lock arm 2 is also provided on the swivel arm base 3.

[0029] One end of the rotating lock arm 2 is rotatably installed in a groove on the rotating arm seat 3 through a cylindrical pin 4, and the other end can rotate back and forth around the cylindrical pin 4 and alternately engage in the lock groove 12 and the clamping groove 13. The lock groove 12 and the clamping groove 13 are located on the circumferential rotation path of the rotating lock arm 2. The two-state functions of locking and opening can be realized by the swinging position of the rotating lock arm 2. The cylindrical pin 4 is a grooved cylindrical pin, and the disassembly and assembly operations are simple, and the maintenance and replacement are convenient and fast.

[0030] The anti-loosening fastener is installed on the rotating lock arm 2 and can lock the rotating lock arm 2 on the lock seat 1 or the clamping seat 5; when the rotating lock arm 2 engages in the lock groove 12 and is locked by the anti-loosening fastener, the door panel and the door frame are locked; when the rotating lock arm 2 engages in the clamping groove 13, the door panel and the door frame are opened; in order to make the anti-loosening fastener lock the rotating lock arm 2 on the lock seat 1 more stably, the side of the anti-loosening fastener facing the lock seat 1 and the side of the lock seat 1 facing the anti-loosening fastener are matched with each other by a convex spherical surface and a concave spherical surface. The specific setting of the spherical surface matching is as follows. To enhance the anti-loosening effect, the anti-loosening fastener includes a knurled ball head locking nut 6, a flange nut 7 and a circlip retainer 8; the knurled ball head locking nut 6 and the flange nut 7 are threadedly connected to the rotating lock arm 2, and the circlip retainer 8 is stuck on the part of the rotating lock arm 2 away from the lock seat 1. The flange nut 7 is located between the knurled ball head locking nut 6 and the circlip retainer 8. At the same time, the ball head of the knurled ball head locking nut 6 faces the lock seat 1. Correspondingly, a spherical surface groove matching with the ball head of the knurled ball head locking nut 6 is provided on the side of the lock seat 1 facing the anti-loosening fastener. The spherical surface groove is communicated with the lock groove 12. The diameters of the spherical surface groove and the ball head of the knurled ball head locking nut 6 are both larger than the diameter of the rotating lock arm 2 and the width of the lock groove 12. Therefore, only after the ball head of the knurled ball head locking nut 6 completely leaves the spherical surface groove of the lock seat 1 can the rotating lock arm 2 leave the clamping groove 12 (otherwise, the rotating lock arm 2 will be restricted by the ball head and it is difficult to leave the clamping groove 12), ensuring effective locking. The knurled ball head locking nut 6 and the flange nut 7 both adopt fine-pitch left-handed threads and medium engagement accuracy. During the running vibration process, the characteristics of the left-handed threads are fully utilized to ensure that the locking state becomes tighter and tighter, which can effectively prevent automatic unlocking and meet the self-locking function.

[0031] Working principle:

[0032] Locking operation: Rotate the rotating lock arm 2 to make the rotating lock arm 2 engage in the lock groove 12 of the lock seat 1. Manually rotate the knurled ball head locking nut 6 counterclockwise (the ball head is downward) to make the ball head of the knurled ball head locking nut 6 screw into the spherical surface groove at the top of the lock seat 1 until the ball head of the knurled ball head locking nut 6 is in close contact with the spherical surface groove of the lock seat 1. Then lock the flange nut 7 and assemble the circlip retainer 8, which is the locked state.

[0033] Opening operation: Loosen the flange face nut 7 to the position of the circlip 8, and then manually rotate the knurled ball head locking nut 6 clockwise so that the ball head of the knurled ball head locking nut 6 disengages from the spherical groove of the lock seat 1 until the ball head of the knurled ball head locking nut 6 completely exits the spherical groove of the lock seat 1. Then, rotate the lock arm 2 90° towards the card seat 5, and press the rotating lock arm 2 into the card slot 13 of the card seat 5, which is the open state. Embodiment 2

[0034] In order to restrain the rotating lock arm 2 after the hatch door is opened, avoid the rotating lock arm 2 from accidentally falling off or deforming during the operation of the equipment, which may affect the opening and closing of the door, and also avoid the rotating lock arm 2 from popping out of the card slot 13 under vibration, which may affect the operation. As Figure 2 shown, the following settings are made in this embodiment on the basis of Embodiment 1:

[0035] There are two installation channels inside the card seat 5, and both ends of each installation channel communicate with the outside of the card seat 5 and the card slot 13; an elastic clamping mechanism is arranged in each installation channel, and the two elastic clamping mechanisms are symmetrically arranged on both sides of the card slot 13. Each elastic clamping mechanism includes a set screw 9, a compression spring 10 and a steel ball 11; the set screw 9 is threadedly connected to the end of the installation channel far from the card slot 13 from the outside of the card seat 5; the steel ball 11 is movably arranged in the end of the installation channel close to the card slot 13 and a part of it extends into the card slot 13. When an external force presses the steel ball 11, the steel ball 11 will shrink into the installation channel. After removing the external force, the steel ball 11 returns to its original position under the action of the compression spring 10; the compression spring 10 is arranged in the installation channel between the set screw 9 and the steel ball 11, and its two ends are respectively connected to the set screw 9 and the steel ball 11. Rotating the set screw 9 can screw the compression spring 10 and the steel ball 11 into or out of the installation channel. At the same time, rotating the set screw 9 can adjust the volume of the steel ball 11 extending into the card slot 13. The disassembly and assembly operations are simple, and the maintenance and replacement are convenient and fast. The distance between the steel balls 11 of the two elastic clamping mechanisms on both sides of the card slot 13 is smaller than the diameter of the rotating lock arm 2 to ensure that the rotating lock arm 2 is restricted in the card slot 13 by the two compression springs 10 and the two steel balls 11, so that when the hatch door is opened, the rotating lock arm 2 will not fall off during the operation of the equipment and affect the opening and closing of the door.

[0036] When opening the hatch, loosen the flange face nut 7 to the position of the circlip 8, and then manually rotate the knurled ball head locking nut 6 clockwise to completely disengage the ball head of the knurled ball head locking nut 6 from the spherical groove of the lock seat 1. Rotate the lock arm 2 90° towards the card seat 5, press the rotating lock arm 2 into the card slot 13 of the card seat 5, and rotate the lock arm 2 to squeeze open the steel balls 11 of the two elastic locking mechanisms (the steel balls 11 retract into the installation channel, and at the same time, the compression spring 10 connected to the steel balls 11 is compressed and stores energy under the extrusion of the steel balls 11), and enter below the steel balls 11. Then, the steel balls 11 reset under the action of the compression spring 10, catch the rotating lock arm 2, and clamp the rotating lock arm 2 by the force of the compression spring 10 and the steel balls 11 on the two symmetrically arranged elastic locking mechanisms to prevent it from falling off.

[0037] Other details not elaborated in the present utility model are all well-known conventional technologies in the art.

[0038] It should be noted that the term "comprising", "including" or any other variant is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0039] The protection scope of the present utility model is not limited to the technical solutions disclosed in the specific embodiments. Any modification, equivalent replacement, improvement, etc. made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
