A quick disassembly device for a control box

Abstract

This invention discloses a quick disassembly device for a control box. A handle movement mechanism is located at the front of the frame, comprising a handle and a handle mounting base. The frame includes an upper crossbeam and a lower crossbeam. The handle passes through the upper crossbeam and is hinged to the upper connecting piece and the handle mounting base via a fixing pin. When the handle rotates, it causes the handle mounting base to slide back and forth along the lower crossbeam. The handle stopping mechanism includes a stop plate, a locking tongue, and a locking seat. The stop plate has a stop hole, and the locking tongue slides along the inner wall of the locking seat, pressing the handle against the outside of the stop hole. The two ends of the stop hole limit the handle's position. The slide rail mechanism includes a guide rail and a top plate. The top plate has a pin, and a claw component engages with the side of the pin via a wedge structure. This converts the rotational motion around the pin into linear motion. The slide rail mechanism, with its claw and pin wedge structure, locks the control panel. The reciprocating motion of the locking tongue contacts the handle, ensuring its physical position. The mechanical interface is concealed, enabling quick connection and disassembly.

Description

Technical Field

[0001] This invention relates to the field of airborne equipment, and more particularly to a quick disassembly device for a control box. Background Technology

[0002] Currently, the installation methods for airborne control boxes in aircraft cockpits are mainly divided into two types: quick-release pin installation and screw installation. Both of these methods result in the installation interface being exposed on the product surface, affecting the neatness and aesthetics of the cockpit. Summary of the Invention

[0003] The purpose of this invention is to provide a device for quick disassembly of a control box.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] A quick disassembly device for a control box, characterized in that it includes a handle movement mechanism, a handle stop mechanism, a slide rail mechanism, and two frames. The two frames extend in the front-to-back direction and are symmetrical in the left-to-right direction. The handle movement mechanism is located at the front of the frames and includes a handle and a handle mounting base. The frames include an upper crossbeam and a lower crossbeam. The handle passes through the upper crossbeam. The lower end of the upper crossbeam has an upper connecting piece protruding from it. The handle and the upper connecting piece are hinged through a through hole by an upper fixing pin. The front ends of the handle and the handle mounting base are hinged through a lower fixing pin. The handle and the handle mounting base are flexibly connected. When the handle rotates, it drives the handle mounting base to slide back and forth along the lower crossbeam.

[0006] The handle stopping mechanism includes a stop plate, a locking tongue, and a lock seat. The stop plate covers the upper end of the frame and has a stop hole. The handle passes through the stop hole, and the locking tongue is embedded in the interior of the lock seat. The locking tongue slides left and right along the inner wall of the lock seat. The locking tongue presses the handle against the outside of the stop hole in the left and right direction. The two ends of the stop hole limit the handle in the front and back direction.

[0007] The slide rail mechanism includes a guide rail and several top plates. The top plates cover the upper end of the frame and are arranged sequentially on the right side of the stop plate. Pins are fixed at the four corners of the top plates and penetrate downward through the upper crossbeam. The guide rail is located above the lower crossbeam. The front end of the guide rail is fixedly connected to the rear end of the handle mounting seat. Several claw components are fixedly provided at the upper end of the guide rail. The claw components are engaged with the sides of the pins through a wedge structure.

[0008] Furthermore, the lock tongue is provided with a spring inside, and the spring has steel balls at both ends along the lateral direction. The inner walls at both ends of the lock seat are provided with grooves, and the steel balls are positioned in the grooves.

[0009] Furthermore, the groove includes a first arc-shaped groove and a second arc-shaped groove arranged sequentially from left to right. The locking tongue moves inward to allow the steel ball to enter the first arc-shaped groove, and the locking tongue moves outward to allow the steel ball to enter the second arc-shaped groove.

[0010] When the steel ball is locked in the center of the first arc-shaped groove, the outer end of the lock tongue is aligned with the outer end of the lock seat.

[0011] When the steel ball is locked in the center of the second arc-shaped groove, the outer end of the locking tongue presses the handle against the outside of the through hole.

[0012] Furthermore, a baffle is provided at the upper end of the latch. When the latch moves inward and the steel ball continues to move inward from the center of the first arc-shaped groove, the baffle of the lock seat limits the further inward movement of the latch.

[0013] Furthermore, the rear end of the claw component is provided with a first wedge, and the side of the pin is provided with a second wedge. The first wedge and the second wedge are inclined at an angle to each other, and the first wedge and the second wedge are correspondingly engaged.

[0014] Furthermore, the claw component includes a support base, which is L-shaped and includes a horizontal plate and a vertical plate. The rear ends of the vertical plate and the horizontal plate are integrally formed. A rigid spring is provided through the front and rear of the vertical plate. A front cover plate is provided at the front end of the horizontal plate along the vertical direction. The front end of the rigid spring is fixedly connected to the rear end of the front cover plate. A claw is fixedly provided at the rear end of the rigid spring. The first wedge is located on the left and right sides of the claw.

[0015] Furthermore, the front end of the handle mounting base is provided with a lower connecting piece, and the lower end of the handle is hinged to the through hole of the lower connecting piece by a lower fixing pin.

[0016] Furthermore, a guide rail base is fixedly provided between the guide rail and the lower crossbeam, and the guide rail and the guide rail base are connected by a needle roller.

[0017] This invention is integrated into a housing consisting of a frame, a stop plate, and a top plate. A handle converts the operator's rotational motion around the pin into reciprocating linear motion. A slide rail mechanism at the bottom of the handle enables synchronized movement of the pawls with minimal energy consumption. The slide rail mechanism features a wedge structure between the pawls and the pin to lock the control panel. The reciprocating movement of the locking tongue contacts the handle, ensuring its physical position. This invention effectively conceals the mechanical interface, enabling quick connection and disassembly, and supports individual disassembly of any device. Attached Figure Description

[0030] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] This invention discloses a quick disassembly device for a control box, such as... Figure 1 As shown, it includes a handle 4 motion mechanism, a handle 4 stop mechanism, a slide rail mechanism, and two frames 1. The two frames 1 extend in the front-to-back direction and are symmetrical in the left-to-right direction. The handle 4 motion mechanism is located at the front of the frame 1. The handle 4 motion mechanism includes a handle 4 and a handle mounting base 5. The frame 1 includes an upper crossbeam 2 and a lower crossbeam 3. The handle 4 passes through the upper crossbeam 2. The lower end of the upper crossbeam 2 has an upper connecting piece 6 protruding from it. The handle 4 and the through hole of the upper connecting piece 6 are hinged by an upper fixing pin 8. The front end of the handle 4 and the handle mounting base 5 are hinged by a lower fixing pin 9. The front end of the handle mounting base 5 has a lower connecting piece 7 protruding from it. The lower end of the handle 4 and the through hole of the lower connecting piece 7 are hinged by a lower fixing pin 9.

[0032] The handle 4 and the handle mounting base 5 are flexibly connected. When the handle 4 rotates, it drives the handle mounting base 5 to slide back and forth along the lower crossbeam 3. The motion mechanism of the handle 4 converts the operator's rotational motion around the fixed pin into reciprocating linear motion.

[0033] The stop mechanism of the handle 4 includes a stop plate 10, a locking tongue 11, and a lock seat 12. The stop plate 10 covers the upper end of the frame 1. The stop plate 10 is provided with a stop hole 13. The handle 4 passes through the stop hole 13. The locking tongue 11 is embedded in the interior of the lock seat 12. The locking tongue 11 slides left and right along the inner wall of the lock seat 12. The locking tongue 11 presses the handle 4 against the outside of the stop hole 13 in the left and right direction. The two ends of the stop hole 13 limit the handle 4 in the front and back direction.

[0034] The lock tongue 11 is equipped with a spring 14 inside. The spring 14 has steel balls 15 at both ends along the lateral direction. The inner walls at both ends of the lock seat 12 are provided with grooves. The steel balls 15 are positioned in the grooves. The grooves include a first arc-shaped groove 16 and a second arc-shaped groove 17 arranged sequentially from left to right. The lock tongue 11 moves inward to allow the steel balls 15 to enter the first arc-shaped groove 16, and the lock tongue 11 moves outward to allow the steel balls 15 to enter the second arc-shaped groove 17.

[0035] When the steel ball 15 is locked in the center of the first arc-shaped groove 16, the outer end of the locking tongue 11 is aligned with the outer end of the lock seat 12; when the steel ball 15 is locked in the center of the second arc-shaped groove 17, the outer end of the locking tongue 11 presses the handle 4 against the outside of the through hole. The reciprocating movement of the locking tongue 11 contacts the handle 4 to ensure the physical position of the handle 4. The self-locking function is achieved through the structure of the spring 14, the steel ball 15 and the two arc-shaped grooves.

[0036] The upper end of the latch 11 is provided with a baffle 18. When the latch 11 moves inward and the steel ball 15 continues to move inward from the center of the first arc-shaped groove 16, the baffle 18 is limited by the lock seat 12 to restrict the latch 11 from moving inward.

[0037] The slide rail mechanism includes a guide rail 20 and several top plates 19. A guide rail base 21 is fixed between the guide rail 20 and the lower crossbeam 3. The guide rail 20 and the guide rail base 21 are connected by rolling needle rollers 22. The slide rail mechanism achieves synchronous movement of the pawl 24 with minimal energy consumption. The sliding friction is converted into rolling friction by the rolling needle rollers 22 between the track and the track base.

[0038] The top plate 19 covers the upper end of the frame 1. The top plate 19 is arranged sequentially on the right side of the stop plate 10. The four corners of the top plate 19 are fixed with pins 23. The pins 23 penetrate downward through the upper crossbeam 2. The guide rail 20 is located above the lower crossbeam 3. The front end of the guide rail 20 is fixedly connected to the rear end of the handle mounting seat 5. Several claw components are fixedly provided at the upper end of the guide rail 20. The claw components are engaged with the side of the pins 23 by a wedge structure.

[0039] The rear end of the claw component has a first wedge protruding out, and the side of the pin 23 has a second wedge protruding out. The first wedge and the second wedge are inclined at the same angle, and the first wedge and the second wedge are engaged accordingly.

[0040] The claw component includes a support base 25, which is L-shaped. The support base 25 includes a horizontal plate and a vertical plate. The rear ends of the vertical plate and the horizontal plate are integrally formed. A rigid spring 26 is provided through the front and rear of the vertical plate. A front cover plate 27 is provided at the front end of the horizontal plate along the vertical direction. The front end of the rigid spring 26 is fixedly connected to the rear end of the front cover plate 27. A claw 24 is fixedly provided at the rear end of the rigid spring 26. The first wedge is located on the left and right sides of the claw 24.

[0041] The wedge mechanism mainly achieves the function of locking the work. It achieves self-locking through the 15° inclined surface between the pawl 24 and the locking pin. Combined with the telescopic structure of the rigid spring 26, it realizes long-term loading of preload and elimination of installation tolerance.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
