In both states, A1 is less than A2 and L1 is greater than L2.
When the door is closed, that is, when the door body 14 and the box body 15 are switched from the open and close states to the locking states, the handheld part 101 is pushed towards the direction approaching the box body 15, the door body 14 moves towards the direction approaching the box body 15, when the first end of the second connecting rod 02 and the second end of the third connecting rod 03 are abutted against the box body 15, that is, when the position of the fifth rotating shaft 08 is abutted against the box body 15, the handheld part 101 is pushed continuously, the position of the fifth rotating shaft 08 is forced to push the second connecting rod 02 to move towards the outer side of the door body 14, meanwhile, the first connecting rod 01 is pushed by the second rotating shaft 05 to move towards the direction approaching the lock hook 13, at the moment, the included angle between the second connecting rod 02 and the third connecting rod 03 is gradually increased, the distance L between the fifth rotating shaft 08 and the first connecting rod 01 is gradually reduced, and the first end of the lock hook 13 is pushed by the first connecting rod 01 and the second connecting rod 02 to rotate anticlockwise around the fourth rotating shaft 07, and the second end of the lock hook 13 is driven to move towards the direction approaching the locking part 122 until the second end of the lock hook 13 is locked with the locking part 122. The movement direction analysis of the first link 01, the second link 02 and the latch hook 13 is shown in fig. 5.
When the door is opened, namely, when the door body 14 and the box body 15 are switched from the locking state to the opening and closing state, the door opening process is a reverse process of the door closing process, specifically, the hand-held part 101 is pulled towards the direction far away from the box body 15, the door body 14 moves towards the direction far away from the box body 15, the first connecting rod 01 moves towards the direction far away from the lock hook 13 under the pushing of the second rotating shaft 05, the third connecting rod 03 moves towards the direction close to the box body 15 under the action of the sixth rotating shaft 09, the second connecting rod 02 moves towards the direction far away from the lock hook 13 under the driving of the third connecting rod 03, at the moment, the included angle between the second connecting rod 02 and the third connecting rod 03 is gradually reduced, the distance L between the fifth rotating shaft 08 and the first connecting rod 01 is gradually increased, the first end of the lock hook 13 is clockwise rotated under the combined action of the first connecting rod 01 and the second connecting rod 02, the second end of the lock hook 13 is driven to move towards the direction far away from the clamping part 122 until the second end of the lock hook 13 is separated from the clamping part 122, when the position 08 of the fifth rotating shaft abuts against the box body 15, the position 08 is continuously pulled, the angle between the position 08 and the door body 14 is opened, and the door 14 is opened under the assistance of the force of the door opening of the door is facilitated when the position of the fifth rotating shaft 08 abuts against the door body.
The second end of the latch hook 13 is provided with a bending part (not labeled) bending towards the direction of the clamping part 122, and a groove matched with the clamping part 122 is formed in the bending part to realize the clamping of the bending part and the clamping part 122. The fourth rotation shaft 07 is disposed between the first end of the latch hook 13 and the second end of the latch hook 13.
The invention fully utilizes the linkage action of the connecting rod assembly to convert the reaction force of the door body 14 impacting the box body 15 into the locking force of the door closing lock hook 13, thereby realizing the locking and the separation of the lock hook 13 and the clamping part 122. The mechanical connecting rod assembly has the advantages of simple structure, high reliability, low cost and convenient maintenance. The upper and lower both ends of the door body 14 and the upper and lower both ends of the box body 15 are respectively locked, the reliability of locking is improved, the sealing performance of the door body 14 is improved, the structure does not occupy the foaming layer of the door body 14, the external aesthetic property of a product is not influenced, and the heat preservation performance of the door body 14 is not influenced.
The upper and lower both ends of the door body 14 are equipped with encapsulation box 11 respectively, and the free end of connecting portion 102 rotates with encapsulation box 11 through first pivot 04 respectively and is connected, and the first end of third connecting rod 03 rotates with encapsulation box 11 through sixth pivot 09 to be connected, and latch hook 13 rotates with encapsulation box 11 through fourth pivot 07 to be connected. Referring to fig. 1 and 2, the packing box 11 is a hollow box-shaped structure, providing an installation space for the hand-held part 101, the link assembly and the rotation shaft assembly. The front side of the package 11 facing the door 14 is provided with an opening (not shown) from which the free end of the connecting portion 102 extends into the interior of the package 11 and is rotatably connected to the bottom of the package 11 by means of the first shaft 04. Thus, the user can see only the handle 10 from the front side of the door body 14, and can not see other parts, which is advantageous for improving the aesthetic appearance of the product. The side of the enclosure 11 facing the housing 15 is also provided with an opening (not shown) so that the fifth spindle 08 extends from the opening to abut the housing 15. When the door 14 and the box 15 are in the locked state, the first connecting rod 01, the second connecting rod 02 and the third connecting rod 03 are all positioned in the packaging box 11, which is also beneficial to improving the aesthetic property of the product.
