Referring to fig. 1 and 2, the handle lock 11 includes a door handle 12, a lock body 41, and a latch 13. When the door handle 12 is forced to rotate downwards, the bolt 13 is driven by the door handle 12 to extend and retract the bolt 13. A rodless cylinder 17 (refer to fig. 6) is arranged above the door handle 12, an L-shaped door sheet 18 is arranged below the rodless cylinder, and the rodless cylinder 17 pushes the L-shaped door sheet 18 downward to realize an unlocking function. Door frame 14 one side is equipped with the cylinder 21 that opens the door that drives test door 1 and open and shut, it is equipped with the door pole 22 that opens the door on the cylinder 21 to open the door, the door pole 22 that opens the door divide into dead lever 28 and dwang 29, dwang 29 is equipped with axis of rotation 3 with dead lever 28 junction, because test door 1 uses test door 1 one side pivot to rotate as the center when opening, the pivoted direction is the arc angle, so adopt dead lever 28 and dwang 29, make the dwang 29 use axis of rotation 3 to rotate as the center and handle test door 1 switch door. The rotating rod 29 is provided with a door catch 40 at one side of the test door 1, the door catch 40 is fixed on the test door 1, the door opening cylinder 21 drives the fixing rod 28 and the rotating rod 29 after being started, and the rotating rod 29 performs door opening action on the test door 1.

Referring to fig. 4 and 6, the rodless cylinder 17 is provided with a push rod 2, and the push rod 2 is connected with a semi-circular push body 39. The L-shaped door sheet 18 is provided with a U-shaped fixing ring 19, and the door handle 12 is wrapped in the U-shaped groove by the U-shaped fixing ring 19. The rodless cylinder 17 drives the semicircular push body 39 through the push rod 2, when the push rod 2 pushes downwards, the semicircular push body 39 pushes downwards and drives the lower L-shaped door piece 18 to move downwards, the U-shaped fixing ring 19 on the L-shaped door piece 18 drives the door handle 12 to rotate downwards, and when the door handle 12 rotates downwards, the lock tongue 13 on the lock body 41 contracts towards the inside of the test door 1, so that the unlocking action of the handle lock 11 is completed. In addition, the door handle 12 has a self-resetting function, so that the door handle 12 is automatically reset when the push lever 2 is retracted.

Referring to fig. 4 and 6, the U-shaped fixing ring 19 includes a threaded post 23 and a support post 24, and the L-shaped door piece 18 is provided with a circular hole 25 correspondingly connected to the U-shaped fixing ring 19. The door handle 12 is fixed in the L-shaped door sheet 18 and the U-shaped fixing ring 19 through the U-shaped fixing ring 19, the tightness degree of the L-shaped door sheet 18 and the U-shaped fixing ring 19 is correspondingly adjusted through the screwing relation between threads on the threaded column 23 and the adjusting nut 26, the U-shaped fixing ring 19 is sleeved with the rubber cushion 27, and the rubber cushion 27 can prevent the handle from being damaged by mechanical equipment to the handle lock 11 in the downward moving process of the U-shaped fixing ring 19. Be equipped with on the door frame 14 and supply the spring bolt 13 to strike gleitbretter 37 when closing the door, be equipped with fillet 38 on the gleitbretter 37, the damage of striking when closing the door of spring bolt 13 to fillet 38 can be reduced to fillet 38, accords with the authenticity that detects more.

Referring to fig. 5, the bottom of the door opening cylinder 21 is provided with a proximity switch 31 and a door stopper 35, an iron sheet 32 is arranged on the test door 1, when the test door 1 is opened towards the proximity switch 31, the iron sheet 32 will gradually approach towards the proximity switch 31, when the iron sheet 32 approaches towards the proximity switch 31 once, the detection device 15 counts the approach times of the proximity switch 31, the door stopper 35 is arranged in front of the proximity switch 31, when the test door 1 is opened, the door stopper 35 can block the test door 1 first, and the test door 1 is prevented from colliding with the proximity switch 31, so that the proximity switch 31 is damaged.

The implementation principle of the embodiment is as follows: test door 1 and handle lock 11 are installed to door frame 14 and are detected after, no pole cylinder 17 will promote catch bar 2 and move down, semicircle push body 39 on catch bar 2 passes L type door leaf 18, the solid fixed ring 19 of U type on the L type door leaf 18 will drive handle lock 11 and rotate down, make spring bolt 13 to the interior shrink of test door 1, the cylinder 21 that opens the door this moment contracts dead lever 28 to the cylinder 21 that opens the door, dead lever 28 will drive dwang 29 to the cylinder 21 direction that opens the door and move, because the opposite side setting of dwang 29 is on test door 1, so will follow the dwang 29 at test door 1 and move. To this end, the test door 1 is unlocked and opened, and after the iron piece 32 of the test door 1 approaches the proximity switch 31, the door opening cylinder 21 conveys the fixed rod 28 and the rotating rod 29 to the door frame 14 in the originally opposite directions, and the latch 13 is retracted into the test door 1 due to its elasticity and one side surface thereof is an inclined surface, and finally is caught in the latch hole 16, thereby completing the door closing operation.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
