Detailed Description

The invention is described in detail below with reference to the figures and examples

Referring to fig. 1 to 9, the opening and limiting structure for the rear door of the wheeled armored vehicle comprises a vehicle body 5, a vehicle door 6 and a vehicle door hinge 7, and is characterized in that:

the limiting hinge 1 consists of a fixed hinge 11, a rotating hinge 12 and a rotating shaft 13, and the plane of the fixed hinge 11 is connected to the vehicle body 5; the end of the vertical face of the rotating hinge 12 is provided with a through hole 15; the end part of the plane of the rotating hinge 12 is provided with a threaded hole 16;

a limiting component 2 is in a groove shape and is positioned and connected on the vehicle door 6; two side walls of the box body are provided with slide grooves 21 which are in mirror symmetry, and one end of the bottom is provided with a stop block 22;

a sliding component 3 is matched and connected with the through hole 15 on the rotating hinge 12 and is matched with sliding grooves 21 on two side walls of the limiting component 2;

a locking member 4 is engaged with the threaded hole 16 of the rotary hinge 12 and is correspondingly contacted with a stop 22 at the bottom of the limiting member 2 to lock the opening position of the rear door of the armored vehicle.

The bottom of the limiting member 2 is provided with two through holes 24, the two through holes 24 are respectively in one-to-one correspondence with the two fixing seats 23 arranged on the vehicle door 6, and the limiting member 2 is fixedly connected to the vehicle door 6 through bolts.

The sliding member 3 is composed of a sliding pin 31 and two nylon sliding sleeves 32, the middle part of the sliding pin 31 is matched with a through hole 15 at the vertical face end of the rotating hinge 12, two ends of the sliding pin 31 are respectively matched with one nylon sliding sleeve 32, and the two nylon sliding sleeves 32 are respectively matched with sliding grooves 21 on two side walls of the limiting member 2 and can slide along the sliding grooves.

The locking component 4 comprises a lock body 41, a lock pin 42 which is matched with the inner cavity of the lock body and the upper end of which extends out of the lock body, a compression spring 43 sleeved on the upper part of the lock pin and a pull ring 44 connected to the upper end of the lock pin, wherein the lower part outside the lock body 41 is provided with a thread section which is matched and connected with the threaded hole 16 on the rotating hinge 12 and is locked by a locking nut 45; the lock pin 42 is in corresponding contact with the stopper 22 of the stopper member 2 provided at the bottom thereof.

The nylon sliding sleeve 32 is of a boss type structure. The hinge and the nylon sliding sleeve can not slide out of the sliding groove of the limiting component, and the sliding track of the hinge can be guaranteed to be rotated, so that the hinge is not in contact with the limiting component, and the reliability is improved.

The working principle of the invention is as follows: when the vehicle door is opened or closed, the limiting component 2 moves along with the vehicle door; at this time, the rotation hinge 12 of the limit hinge 1 is driven to move under the limit of the sliding groove 21 of the nylon sliding sleeve 32. When the opening angle of the vehicle door 6 is about 90 degrees, the rotating hinge 12 of the limiting hinge 1 does not move outwards any more under the limitation of the nylon sliding sleeve 32 and the sliding groove 21, and finally the vehicle door is ensured not to be opened outwards any more; meanwhile, the stopper 22 at the bottom of the stop member 2 blocks the lock pin 42 of the locking member 4, so that the vehicle door 6 is prevented from rebounding, namely, the vehicle door 6 is always kept in a 90-degree opening state. When the door needs to be closed, the pull ring 44 of the lock pin 42 is slightly pulled up, the compression spring 43 is compressed, the lock pin 42 of the locking member 4 passes over the stop 22 at the bottom of the stop member 2, and the door returns to the free rotation state, so that the door can be closed.

The fixed hinge 11, the rotating hinge 12 and the rotating shaft 13 in the limiting hinge 1 are all made of No. 45 steel, and the hardness of the limiting hinge after heat treatment is 30-35 HRC; the cross section of the fixed hinge 11 is 50mm multiplied by 14mm, the cross section of the rotating hinge 12 is 27mm multiplied by 8mm, and the diameter phi of the rotating shaft 13 is 10mm, so that the overall structural strength of the limiting hinge 1 is ensured. Meanwhile, a zinc-nickel infiltration layer is formed on the surface, and the thickness of the infiltration layer is 60-90 microns, so that the corrosion resistance of the limiting hinge 1 is ensured; the surface zinc-nickel infiltration layer is treated and then is treated by plastic spraying, so that the integral attractiveness is improved.

The sliding part of the rotating hinge 12 in the limiting component 2 is subjected to transition treatment by a nylon sliding sleeve, so that a certain buffering effect is achieved, and the surface coatings of the stay bar hinge 12 and the limiting sliding groove 2 can be protected from being damaged.

The locking component 4 is made of stainless steel, mounting threads M16 multiplied by 1.5mm on the lock pin shell 41 are provided with the lock nut 45, and the locking component 4 can be guaranteed to be mounted firmly and reliably. The diameter of the lock pin is 10mm, the stop block 22 in the limiting component 2 is made of 45# steel, and the hardness after heat treatment is 35-40HRC, so that the limit component can bear enough impact load during limiting.
