In use, the door frame portion connecting piece is fixed (typically by screws) to the door frame and the door panel portion connecting piece is mounted on the rear surface of the door panel. When the door is latched, the gripper rod is held to move the plug pin towards the plug bush, simultaneously, the stop pin is required to be contracted when passing through the plug bush so as to pass through the plug bush, and then the plug pin is inserted into the plug bush; when the door bolt is opened, the gripper rod is held to move the plug pin towards the direction far away from the plug bush, meanwhile, the stop pin is required to be pressed to enable the stop pin to be kept in a contraction state and to enter the plug bush, and then the plug pin is pulled out of the plug bush. This technical scheme is owing to increased backing pin and relevant structure for need press the backing pin and just can pass through the plug bush when opening, thereby can not realize opening when making to stir the bolt through the card from outdoors, play the effect that improves the security.
Preferably, the catch pin and the gripper bar are located on the same side of the latch. Can make when normally opening in inside, can conveniently grip the tongs pole and can conveniently press the backing pin again.
Preferably, the stop pin is provided with a driving inclined surface which is matched with the plug bush when the plug pin is inserted into the plug bush to drive the plug pin to shrink towards the connecting hole, so that the stop pin passes through the plug bush along with the plug pin. When the plug pin is inserted, the stop pin does not need to be additionally operated, and the convenience of inserting the plug pin is improved.
Preferably, the door panel connecting piece is provided with a stop block which is matched with the gripper bar to stop the bolt from being separated from the sliding sleeve, and the gripper bar is positioned between the stop block and the sliding sleeve. The bolt can be prevented from falling off due to excessive movement.
Preferably, the stopper is a stamping integrally formed on the door panel connecting sheet. During manufacturing, the check block is formed by stamping one side of the sliding sleeve, which is far away from the sliding sleeve from the door plate part connecting piece, towards the door plate part connecting piece, so that the convenience during manufacturing and the simplicity of the structure are improved.
Preferably, the stop block and the two sliding sleeves are positioned on the same straight line.
Preferably, the pin is circular. The smoothness is good when moving the bolt.
Preferably, the latch is held in a state in which the gripper bar extends downward by a moment generated by a weight of the gripper bar when the door panel portion connecting piece is fixed on the rear surface of the door panel. When the bolt is not operated, the gripper rod is automatically stored in a vertical mode, the gripper rod is stored in a vertical state and is protruded, the protrusion is small, the gripper rod cannot be collided easily, and the gripper rod is hooked to people or objects, so that the safety is good.
The utility model has the advantages of that: except the translation bolt, still need the bolt to press the backing pin and make the backing pin keep just can be opened in the contraction status when opening, so can prevent effectively to be opened through the mode of stirring from the door outward to make safety obtain very big improvement.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to fig. 1, 2 and 3, a cellular board latch structure includes a latch 1, a door frame portion connecting piece 2 for connecting to a door frame, and a door panel portion connecting piece 3 for connecting to a rear surface of a door panel. The door frame connecting piece is provided with an inserting sleeve 4 for inserting the inserted pin so as to latch the door plate and the door frame together. The door panel connecting sheet is provided with two sliding sleeves 5 and a stop block 6. The stop dog is a stamping part which is integrally formed on the door panel part connecting sheet. The stop block and the two sliding sleeves are positioned on the same straight line. The bolt is simultaneously arranged in the two sliding sleeves in a penetrating way. One end of the bolt is provided with a gripper bar 7 extending along the radial direction of the bolt. The circumferential surface of the other end of the bolt is provided with a connecting hole 8. When the bolt is inserted into the plug bush to the grab handle and the sliding bush is abutted together. The plug bush is positioned between the connecting hole and the sliding bush. A stop pin 9 and a spring 10 which drives the stop pin to extend out of the connecting hole to prevent the plug pin from being pulled out of the plug bush are arranged in the connecting hole. The stop pin can be pressed into the connecting hole to pass through the plug bush along with the plug pin. The stop pin and the gripper bar are positioned on the same side of the plug pin. The stop pin is provided with a driving inclined plane 11 which is matched with the plug bush when the plug pin is inserted into the plug bush to drive the plug pin to shrink towards the connecting hole so that the stop pin passes through the plug bush along with the plug pin. The bolt can not continue to move under the blocking effect of the stop dog after being pulled out of the plug bush, so that the bolt is maintained in the sliding sleeve. The gripper bar is positioned between the stop block and the sliding sleeve. The bolt is circular. When the door panel portion connecting piece is fixed on the rear surface of the door panel, the latch is kept in a state where the gripper bar extends downward under the action of the moment generated by the weight of the gripper bar.
In use, the door frame portion connecting piece is fixed to the door frame 12, and the door panel portion connecting piece is mounted on the rear surface of the door panel 13. When the door is latched, the gripper rod is held to move the plug pin towards the plug bush, when the plug pin moves to the driving inclined plane 11 to be contacted with the plug bush, the plug bush extrudes the driving inclined plane to enable the stop pin to shrink to generate avoidance, the avoidance result is that the stop pin passes through the plug bush along with the plug pin, and the stop pin is popped out again after passing through the plug bush. When the bolt is opened, the bolt is moved in the direction away from the plug bush by holding the gripper rod, and meanwhile, the stop pin is pressed by the finger head so that the stop pin is kept in a contraction state and can enter the plug bush, and the bolt is pulled out of the plug bush. The grip rod is held in a manner that the grip rod is kept perpendicular to the door panel in the above process.
