A guide groove 112f is provided on the bottom groove wall 112e of each locking component mounting groove 112. The guide groove 112f is parallel to the length of the locking component mounting groove 112 and is used to guide the locking drive shaft 410 in the locking component. In addition, a spring stopper 112g is provided on the bottom groove wall 112e of each locking component mounting groove 112, located between the locking component mounting groove 112 and the end groove wall 112c.

[0048] A locking shaft telescopic hole 112h is provided on the end groove wall 112c, so that the locking shaft 420 in the locking component can pass through and perform telescopic movement in the locking shaft telescopic hole 112h.

[0049] A boss 121 a is provided at the top of the locking component installation slot cover 121 in the width direction. The boss 121 a also contacts the unlocking handle 200 in a small area and cooperates with the blocking bar 111 c to guide the extension and retraction of the unlocking handle 200 .

[0050] Multiple hooks 122a are provided on both sides of each locking component installation slot cover plate 122 in the width direction, at the ends, and at the connection with the locking component installation slot cover plate 122. These hooks 122a snap onto corresponding buckles 112, securing the cover 120 to the housing 110. Pressing strips 122b are provided on the left and right locking component installation slot cover plates 122. These pressing strips 122b press the locking drive shaft 410 into the guide slot 112f.

[0051] The two unlocking handles 200 are installed in the middle installation groove 111 in a relative manner and are covered by the middle installation groove cover 121. The two bosses 122a cooperate with the two block bars 111c. Each boss 122a cooperates with each block bar 111c to jointly press down an unlocking handle 200 and guide an unlocking handle 200.

[0052] A guide rail block 210 is provided on each left and right side of the length direction of each unlocking handle 200. The guide rail block 210 cooperates with the groove walls on the left and right sides of the length direction of the middle mounting groove 111 for guidance, and at the same time cooperates with the limit strips 111d on both sides of the top at both ends of the width direction of the middle mounting groove 111 to limit the unlocking handle 200 from falling out of the middle mounting groove 111.

[0053] Each unlocking handle 200 is provided with an axial hole 220 on either side of its length for insertion of the unlocking handle shaft 510 in the unlocking handle reset mechanism 500. Reinforcing ribs 230 are provided within each unlocking handle 200 to increase its strength. Each unlocking handle 200 is also provided with a drive handle 240 for rotating the disc 300. The tail of each drive handle 240 is cylindrical.

[0054] The disc 300 is installed in the middle installation groove 111 through a central shaft 310 . An axis hole 310 is provided at the center of the disc 300 . The central shaft 310 passes through the central axis hole 111 b and the axis hole 310 . The disc 300 can rotate around the central shaft 310 .

[0055] One end of the central shaft 310 has a flange 311 that engages with the bottom wall 112e of the locking member mounting groove 112 to limit the axial movement of the central shaft 310. A retaining spring groove 313 is appropriately positioned on the shaft portion 312 of the central shaft 310. After the central shaft 310 passes through the axial hole 310 of the disk 300, a retaining spring 350 engages with the retaining spring groove 313 to axially limit the disk 300, preventing it from rotating only about the central shaft 310 and preventing it from moving axially along the central shaft 310.

[0056] Two guide grooves 320 are evenly spaced around the disc 300, with a snap-in groove 330 at the end of each guide groove 320. During assembly, the driving handles 240 fit into the guide grooves 320, with the tail of each driving handle 240 nestled within the snap-in groove 330 to prevent it from falling out. When the two unlocking handles 200 are pressed, the tails of the driving handles 240 on the two unlocking handles 200 drive the disc 300 to rotate in the third direction, i.e., clockwise, to unlock the device.

[0057] Two driving arcuate grooves 340 are symmetrically provided on the end surface of the disc 300 . The two driving arcuate grooves 340 are used to drive the locking driving shafts 410 in a pair of locking components to move.

[0058] Each set of locking components includes a locking drive shaft 410, a locking shaft 420, and a locking shaft return spring 430. The locking drive shaft 410 is made of plastic, and the middle part of the locking drive shaft 410 is a cavity structure to achieve lightweighting of the entire disc pressing and shrinking assembly.

[0059] A cylinder 411 is provided at the first end of the locking drive shaft 410. The cylinder 411 is inserted into the driving arc groove 340 and can move in the driving arc groove 340, so that the locking drive shaft 410 is driven and connected to the disc 300, so that the rotation of the disc 300 is converted into linear motion of the locking drive shaft 410.

[0060] A shaft hole 412 is provided at the second end of the locking drive shaft 410. A knurled shaft 421 at one end of the locking shaft 420 is inserted into the shaft hole 412 with an interference fit, connecting the locking shaft 420 to the first end of the locking drive shaft 410. Furthermore, a stepped groove 422 is provided at an appropriate position in the middle of the locking shaft 420, into which a spring retaining spring 440 is inserted. A locking shaft return spring 430 is sleeved on the locking shaft 420. One end of the locking shaft return spring 430 acts on the spring retaining spring 440, and the other end acts on the spring limit stop 112g.

[0061] Each unlock handle reset mechanism 500 includes an unlock handle shaft 510 and two unlock handle reset springs 520. During installation, the unlock handle shaft 510 passes through the inner hole of the shaft seat 117. Two stepped surfaces 511 and 512 are appropriately positioned in the middle of the unlock handle shaft 510. The two stepped surfaces 511 and 512 are located at the axial ends of the shaft seat 117, respectively, to limit the axial position of the unlock handle shaft 510, so that the unlock handle shaft 510 can only rotate on the shaft seat 117 and cannot move axially. The two ends of the unlock handle shaft 510 are respectively inserted into the shaft hole 220 of the unlock handle 200, which also guides the movement of the unlock handle 200.

[0062] The two unlocking handle return springs 520 are respectively sleeved on the two ends of the unlocking handle 200 . One end of the two unlocking handle return springs 520 acts on the step surfaces 511 and 512 , and the other end acts on the two unlocking handles 200 .

[0063] The working principle of this utility model is as follows:

[0064] To unlock, the two unlocking handles 200 are pressed. The tail ends of the drive handles 240 of the two unlocking handles 200 drive the disc 300 in the third direction, i.e., clockwise. At this time, the four unlocking handle return springs 520 compress and store energy. As the disc 300 rotates clockwise, the two arcuate drive slots 340 on the disc 300 pull the locking drive shaft 410 of the locking component back in the first direction. The pulled back locking drive shaft 410 drives the locking shaft 420 to retract, unlocking the door. At this time, the locking shaft return spring 430 compresses and stores energy.

[0065] When locking is required, the two unlocking handles 200 are released, eliminating the pressing force on the two unlocking handles 200. The four unlocking handle return springs 520 are released, driving the two unlocking handles 200 to return to their original positions. During the return process, the tail ends of the drive handles 240 of the two unlocking handles 200 drive the disc 300 to rotate in the fourth direction, i.e., counterclockwise, to return to their original positions. During the return process, the two arcuate drive slots 340 on the disc 300 release the locking drive shaft 410 of the locking component in the second direction described above. With the release of the locking shaft return springs 430, the locking shaft 420 returns to the locked position.
