[0010] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation methods of the present invention are further described in detail below.

[0011] The utility model proposes an adjustable armored vehicle top door power-assisting mechanism, comprising: a top door 1, a power-assisting torsion bar 2, a torsion bar sleeve 3, a bushing 4, a clamping seat 5, a torsion bar fixing seat 6, a connecting plate 7, a rubber plug 8, a door attachment seat 9, a locking screw 10, a sealing ring 11, a locking handle 12, a handle connecting seat 13, a support 14, a ring beam 15, a limit pin 16, a vehicle body top deck 17 and a wedge 18.

[0012] The top door 1 and the torsion bar sleeve 3 are welded together through the connecting plate 7. The door attachment seat 9 is welded to the top deck 17 of the vehicle body. The clamping seat 5 and the support 14 are fixed to the door attachment seat 9 with bolts. The two ends of the torsion bar sleeve 3 are respectively inserted into the holes of the support 14 and the clamping seat 5. Non-metallic bushings 4 are placed between the support 14 and the torsion bar sleeve 3, and between the clamping seat 5 and the torsion bar sleeve 3 to reduce friction. The torsion bar sleeve 3 rotates, and the door attachment seat 9 plays a supporting role.

[0013] The square head at one end of the power-assisting torsion bar 2 is inserted into the square hole at the end of the torsion bar sleeve 3, and the torsion bar fixing seat 6 is inserted into the hole of the clamping seat 5, so that they can rotate relatively. At the same time, the square head at the other end of the power-assisting torsion bar 2 is inserted into the square hole of the torsion bar fixing seat 6. When the top door 1 is opened to the open position, the locking screw 10 on the clamping seat 5 is tightened to clamp the torsion bar fixing seat 6, so as to achieve the purpose of adjusting the torsion angle of the torsion bar;

[0014] The rubber plug 8 is inserted into the holes of the torsion bar fixing seat 6 and the end of the torsion bar sleeve 3.

[0015] The handle connector 13 is welded to the inner surface of the top door 1. The locking handle 12 is threadedly connected to the handle connector 13. One end of the stop pin is installed in the hole of the locking handle 12, and the other end of the stop pin 16 enters the notch of the handle connector 13 to prevent the locking handle 12 from falling off. The sealing ring 11 is installed in the annular groove of the top door 1. The ring beam 15 is welded to the opening of the top deck 17 of the vehicle body, and the wedge 18 is welded to the ring beam 15.

[0016] Its working principle is as follows: See the figure. When the top door 1 is opened to a certain angle, tighten the locking screw 10 to adjust the torsion angle of the torsion bar. The clamping seat 5 clamps the torsion bar fixing seat 6. When the door is closed, the top door 1 drives the torsion bar sleeve 3 to rotate in the bushing 4 through the connecting plate 7. The square hole of the torsion bar sleeve 3 rotates the square head of the assisting torsion bar 2. The square head of the other end of the assisting torsion bar 2 is connected to the torsion bar fixing seat 6. After the screw 10 is tightened, the clamping seat 5 fixes the torsion bar fixing seat 6 to the top deck 17. The assisting torsion bar 2 is twisted to a certain angle. The torsion of the assisting torsion bar 2 and the downward torque generated by the gravity of the top door 1 are offset, reducing the operating force of the top door 1. The assisting amount of the assisting torsion bar 2 is determined according to the size of the top door 1. Adjust the opening angle of the top door 1 and tighten the screw 10 on the clamping seat 5. Adjust the assisting amount of the torsion bar 2. After closing the top door 1, the locking handle 12 is rotated. The stud of the locking handle 12 rotates within the threads of the handle connector 13. The pressing end of the locking handle 12 presses against the wedge 18, pressing the sealing ring 11 against the ring beam 15, closing and sealing the top door 1. To open the door, the locking handle 12 is rotated, sliding off the wedge 18. The top door 1 is opened by the torque of the auxiliary torsion bar 2 and the push of the person. This reduces the force required to open and close the door.

[0017] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
