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.
[0022] As Figures 1 to 6 shown, the embodiment of the present invention provides a hatch mechanical lock, which includes a handle 1, a lock box 2, a hatch 3, a lock pin 4, a locking block 5 and an elastic member 6.
[0023] As Figure 5 shown. The hatch 3 is connected to the lock box 2. The lock box 2 is provided with ear plates, and threaded holes are provided on the ear plates so that the lock box 2 and the hatch 3 can be connected by bolts.
[0024] In practical applications, a limit groove 21 is provided on the side wall of the lock box 2. As Figure 2As shown, the shape of the limit groove 21 is L-shaped.
[0025] Continue to refer to Figure 2 As shown, a limit hole 51 is provided on the locking block 5. One end of the locking pin 4 is located in the inner cavity of the lock box 2, and the other end of the locking pin 4 extends out of the limit groove 21 to the outside. In practical applications, the end of the locking pin 4 extends into the limit hole 51 to lock the access panel mechanical lock.
[0026] As Figure 4 As shown, one end of the handle 1 passes through the access panel 3 and is connected to the locking pin 4, so that when the handle 1 rotates, it can drive the locking pin 4 to approach or move away from the limit hole 51. The elastic member 6 is arranged in the inner cavity of the lock box 2 and is located below the locking pin 4. When the locking pin 4 and the limit hole 51 are aligned, the locking pin 4 pops out and is clamped in the limit hole 51 to limit the locking pin 4. In actual use, first place the access panel mechanical lock at a suitable position on the fuselage, then rotate the handle 1. The rotation of the handle 1 drives the locking pin 4 to rotate in the limit groove 21. When the locking pin 4 rotates to align with the limit hole 51, the locking pin 4 slides out of the limit groove 21 under the elastic force of the elastic member 6, and the end of the locking pin 4 extends into the limit hole 51 to lock the access panel mechanical lock; when it is necessary to unlock the access panel mechanical lock, press the handle 1 downward to compress the elastic member 6. At this time, the locking pin 4 is disengaged from the limit hole 51, then rotate the handle 1. The rotation of the handle 1 drives the locking pin 4 into the limit groove 21, and continue to rotate the handle 1 to separate the end of the locking pin 4 from the locking block 5 to unlock the access panel mechanical lock. The access panel mechanical lock of the present application has a simple structure, can be disassembled and assembled without tools, is easy to operate and has a high disassembly and assembly efficiency.
[0027] An embodiment of the present utility model provides a mechanical hatch cover lock, which includes a handle 1, a lock box 2, a hatch cover 3, a lock pin 4, a locking block 5 and an elastic member 6. The hatch cover 3 is connected to the lock box 2. A limiting groove 21 is formed in the side wall of the lock box 2. A limiting hole 51 is formed in the locking block 5. One end of the lock pin 4 is located in the inner cavity of the lock box 2, and the other end of the lock pin 4 extends out of the limiting groove 21 to the outside. One end of the handle 1 passes through the hatch cover 3 and is connected to the lock pin 4, so that when the handle 1 rotates, the lock pin 4 can be driven to approach or move away from the limiting hole 51. The elastic member 6 is arranged in the inner cavity of the lock box 2 and is located below the lock pin 4. When the lock pin 4 corresponds to the limiting hole 51, the lock pin 4 pops out and is clamped in the limiting hole 51 to realize the limiting of the lock pin 4. During actual use, first place the mechanical hatch cover lock at a suitable position on the fuselage, and then rotate the handle 1. The rotation of the handle 1 drives the lock pin 4 to rotate in the limiting groove 21. When the lock pin 4 rotates to correspond to the limiting hole 51, the lock pin 4 slides out of the limiting groove 21 under the elastic force of the elastic member 6, and the end of the lock pin 4 extends into the limiting hole 51 to realize the locking of the mechanical hatch cover lock; when it is necessary to unlock the mechanical hatch cover lock, press down the handle 1 to compress the elastic member 6. At this time, the lock pin 4 is disengaged from the limiting hole 51, and then rotate the handle 1. The rotation of the handle 1 drives the lock pin 4 into the limiting groove 21, and continue to rotate the handle 1 to separate the end of the lock pin 4 from the locking block 5 to realize the unlocking of the mechanical hatch cover lock. The mechanical hatch cover lock of the present application has a simple structure, can be disassembled and assembled without tools, and has simple operation and high disassembly and assembly efficiency.
[0028] As Figure 4 shown, the mechanical hatch cover lock further includes a limiting member 7. The limiting member 7 is arranged in the inner cavity of the lock box 2, and one end of the limiting member 7 is connected to the end of the handle 1. The elastic member 6 is sleeved on the limiting member 7. A first through hole 22 matching the limiting member 7 is formed in the bottom of the lock box 2. Specifically, the arrangement of the limiting member 7 facilitates the installation of the elastic member 6.
[0029] In practical applications, the elastic member 6 includes a torsion spring. Specifically, since the torsion spring has an automatic reset function, when unlocking the mechanical hatch cover lock, only need to press down the handle 1 to disengage the lock pin 4 from the limiting hole 51, then rotate the handle 1 to make the lock pin 4 enter the limiting groove 21, and then the torsion spring resets to drive the handle 1 to rotate, and the handle 1 drives the end of the lock pin 4 to separate from the locking block 5 to realize the unlocking of the mechanical hatch cover lock, with simpler operation and higher unlocking efficiency.
[0030] Specifically, a sealing ring is arranged at the position where the hatch cover 3 contacts the handle 1. In practical applications, the sealing ring can seal the hatch cover 3 to ensure the rainproof effect.
[0031] As Figure 6As shown, a guide rail groove 52 is formed on the locking block 5, and the end of the guide rail groove 52 coincides with the limit hole 51. Specifically, the setting of the guide rail groove 52 can make the movement track of the locking pin 4 more accurate, so as to ensure that the end of the locking pin 4 can extend into the limit hole 51 more precisely.
[0032] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, reference can be made to each other. The key point of each embodiment is to illustrate the differences from other embodiments.
[0033] The above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting the present application; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the present application.
