[0080] This structure is used when the hatch needs to be locked from the outside. This structure does not occupy the internal space of the hatch. After external locking, that is, rotating the locking handle 2 so that its locking end engages with the wedge block 3, use the hatch key 1 to tighten the internal stop screw 10 of the handle so that the lower end of the stop screw is stuck in the limiting hole 503 of the fixed shaft 5, which can prevent the handle from being automatically unlocked due to vibration.

[0081] Example 5:

[0082] An external locking structure for an armored vehicle hatch, the main technical content of which is shown in Example 4. Furthermore, the locking handle 2 is provided with a V-shaped groove 204 at the bottom of one side of the extended section.

[0083] The positioning pin 8 is stuck in the V-shaped groove 204 of the locking handle 2 to prevent the locking handle 2 from shaking and self-locking.

[0084] When the hatch does not need to be locked externally, rotate the locking handle clockwise to make the end of the positioning pin 8 pop out through the spring and get stuck in the V-groove below the locking handle to prevent the handle from shaking and locking itself.

[0085] Example 6:

[0086] An external locking structure for an armored vehicle hatch, the main technical content of which is shown in any one of Examples 4 to 5. Furthermore, when the extended section of the locking handle 2 is in a separated state from the wedge block 3, the lower end of the stop screw 10 protrudes from the lower end surface of the locking handle 2, and the end of the stop screw 10 is lower than the top of the fixing bolt 12. The fixing bolt 12 limits the rotation of the locking handle 2 to prevent the locking handle 2 from shaking and self-locking.

[0087] The locking handle can also be rotated clockwise to the position, that is, when the handle cannot be turned, use the hatch key 1 to tighten the stop screw 10 inside the handle so that the lower end of the stop screw protrudes a certain height from the lower end surface of the locking handle. At this time, the fixing bolt on the fixed shaft 5 will limit the rotation of the locking handle to prevent self-locking. Because when the handle rotates, the stop screw 10 on the handle will interfere with the fixing bolt, preventing the locking handle from self-locking under large vibrations of the vehicle.

[0088] When the locking handle is unlocked, the locking handle Figure 2 On the basis of the screw, rotate it clockwise about 86°. At this time, the threaded hole I203 at the bottom of the groove I202 on the locking handle will pass over the bolt 12 installed on the base. At this time, screw the stop screw 10 to the lower end of the threaded hole I203 so that the end of the stop screw 10 is lower than the top of the bolt of the fixing bolt 12 in the height direction. In this way, the fixing bolt 12 will limit the rotation of the locking handle 2 to prevent the locking handle 2 from self-locking.

[0089] Example 7:

[0090] See also Figures 1 to 4 , an external locking structure for an armored vehicle hatch, the main technical contents are as follows:

[0091] Weld a base 4 to the vehicle body deck at the external locking point of the hatch, weld a wedge block 3 on the hatch, install the fixed shaft 5 on the base with bolts 12, install the spring 7 and the locating pin 8 inside the fixed shaft, then install the locking handle 2 on the fixed shaft and fix it with a nut 6, then install the set screw in the threaded hole of the locking handle, and then spot weld the limiting cover 11 on the opening of the threaded hole of the locking handle, limiting the opening here so that only the hatch key 1 can be inserted.

[0092] This structure is used when the hatch needs to be locked from the outside. This structure does not occupy the internal space of the hatch. After external locking, that is, rotating the locking handle 2 so that its locking end engages with the wedge block 3, use the hatch key 1 to tighten the internal stop screw 10 of the handle so that the lower end of the stop screw is stuck in the limiting hole 503 of the fixed shaft 5, which can prevent the handle from being automatically unlocked due to vibration.

[0093] When the hatch does not need to be locked from the outside, rotate the locking handle clockwise so that the end of the locating pin 8 pops out through the spring and gets stuck in the V-groove below the locking handle to prevent the handle from shaking and self-locking. The locking handle can also be rotated clockwise into position. That is, when the handle cannot be turned, use the hatch key 1 to tighten the stop screw 10 inside the handle so that the lower end of the stop screw protrudes a certain height from the lower end surface of the locking handle. At this time, the fixing bolt on the fixed shaft 5 will limit the rotation of the locking handle to prevent self-locking. Because when the handle rotates, the stop screw 10 on the handle will interfere with the fixing bolt, preventing the locking handle from self-locking under large vibrations of the vehicle.
