Description

Technical Field

[0001] The utility model belongs to the technical field of internal and external locking, and in particular relates to an internal and external locking mechanism. Background Art

[0002] Chinese patent announcement number CN217260489U applies for a hidden internal card self-locking mechanism, which includes a hidden button connected to the internal card locking assembly. Specifically, a second accommodating portion is provided on the second connector corresponding to the hidden button, the hidden button is adapted to be in the second accommodating portion, and the hidden button moves in the second accommodating portion when pressed or popped up, and so on.

[0003] It is not difficult to know from its description and drawings that this hidden external button is unlocked by pressing and rebounding, but its shortcomings are as follows: First, this button that bears the lock of two connectors often has a large friction resistance, and sometimes it is not easy to press and unlock, and it is more laborious; second, the button may cause the spring to age if it is pressed for a long time, which may cause the button to be stuck in the button slot, making it difficult to unlock the connector, so it needs to be improved. Therefore, an internal and external locking mechanism is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an internal and external locking mechanism to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an inside-outside locking mechanism, comprising a first joint and a second joint, wherein a first clamping portion and a second clamping portion are respectively arranged inside the first joint and the second joint, a pressing groove is jointly provided on one side of the first clamping portion and the second clamping portion, a connecting block is fixedly arranged inside the pressing groove, a protruding portion above the connecting block is rotatably connected to an outer locking pressing block, one side of the outer locking pressing block is fixedly connected to a spring, one end of the spring is fixedly connected to the connecting block, the spring is away from the rotation point of the outer locking pressing block and the connecting block, the outer locking pressing block is adapted to the pressing groove, and one side of the upper part of the outer locking pressing block is slightly arc-shaped and clamped on one side of the first clamping portion.

[0006] By arranging the outer lock pressing block and the connecting block to rotate, when it is necessary to unlock the clamping connection of the outer lock pressing block to the first clamping part, it is only necessary to press the lower side of the outer lock pressing block. The pressing of the outer lock pressing block 7 will drive the expansion and contraction of the spring. At the same time, the clamping connection above the outer lock pressing block is tilted through the rotation fulcrum of the outer lock pressing block and the connecting block, thereby releasing the external clamping connection with the first clamping part. During this period, the outer lock pressing block uses the lever principle to unlock the outer lock pressing block through the rotation fulcrum, which is more labor-saving and can release the lock more easily. Moreover, through the rotational unlocking method, even if the spring is aged, it will not affect its rotational unlocking, thereby ensuring the unlocking of the joint to a certain extent.

[0007] As a preferred implementation, an eccentric handle is eccentrically rotatably provided on the first joint.

[0008] As a preferred embodiment, an adapting groove is formed on one side of the second joint, and the eccentric handle is clamped in the adapting groove.

[0009] As a preferred embodiment, an inner locking connecting rod is provided at a rotating portion of one side of the eccentric handle through a rotating ring.

[0010] As a preferred implementation, one end of the inner locking connecting rod is threadedly fixedly connected to an inner locking block.

[0011] As a preferred implementation, one side of the first clamping portion and one side of the second clamping portion are both clamped on the inner locking block.

[0012] By setting an eccentric handle, when the eccentric handle is taken out of the adapter groove, the eccentric rotation of the eccentric handle at the swivel can drive the inner locking link to move to a certain extent. During this period, the inner locking link is limited by the jack at the connection between the second joint and the first joint, so that the inner locking block can easily release the internal lock with the first clamping part and the second clamping part.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model provides an outer lock pressing block and a connecting block for rotation. When it is necessary to unlock the clamping connection of the outer lock pressing block to the first clamping part, it is only necessary to press the lower side of the outer lock pressing block. The pressing of the outer lock pressing block 7 will drive the expansion and contraction of the spring. At the same time, the clamping connection above the outer lock pressing block is tilted through the rotation fulcrum of the outer lock pressing block and the connecting block, thereby releasing the external clamping connection with the first clamping part. During this period, the outer lock pressing block is unlocked by rotating the fulcrum, which is a lever principle, which is more labor-saving and can release the lock more easily. Moreover, through the rotational unlocking method, even if the spring is aged, it will not affect its rotational unlocking, thereby ensuring the unlocking of the joint to a certain extent.

[0015] The utility model provides an eccentric handle. When the eccentric handle is taken out of the adapter groove, the eccentric rotation of the eccentric handle at the rotating ring can drive the inner locking link to move to a certain extent. During this period, the inner locking link is limited by the jack at the connection between the second joint and the first joint, so that the inner locking block can easily release the internal lock with the first clamping part and the second clamping part.

[0023] By arranging the outer lock pressing block 7 and the connecting block 6 to rotate, when it is necessary to unlock the clamping connection of the outer lock pressing block 7 to the first clamping part 3, it is only necessary to press the lower side of the outer lock pressing block 7. The pressing of the outer lock pressing block 7 will drive the expansion and contraction of the spring 8. At the same time, the clamping part above the outer lock pressing block 7 is tilted through the rotation fulcrum of the outer lock pressing block 7 and the connecting block 6, thereby releasing the external clamping connection with the first clamping part 3. During this period, the unlocking method of the outer lock pressing block 7 through the rotation fulcrum based on the lever principle is more labor-saving and can release the lock more easily. Moreover, through the rotational unlocking method, even if the spring 8 is aged, it will not affect its rotational unlocking, thereby having a certain degree of guarantee for the unlocking of the joint.

[0024] An eccentric handle 9 is eccentrically rotatably provided on the first joint 1 .

[0025] An adapting groove 10 is formed on one side of the second joint 2 , and the eccentric handle 9 is clamped in the adapting groove 10 .

[0026] An inner locking link 12 is rotatably provided at a rotating portion of one side of the eccentric handle 9 through a swivel 11 .

[0027] As a preferred implementation, one end of the inner locking connecting rod 12 is threadedly fixedly connected to an inner locking block 13 .

[0028] One side of the first clamping part 3 and the second clamping part 4 are both clamped on the inner locking block 13. By providing an eccentric handle 9, when the eccentric handle 9 is taken out of the adapter groove 10, the eccentric rotation of the eccentric handle 9 at the swivel 11 can drive the inner locking link 12 to move to a certain extent. During this period, the inner locking link 12 is limited by the jack at the connection between the second joint 2 and the first joint 1, so that the inner locking block 13 can easily release the internal lock with the first clamping part 3 and the second clamping part 4.

[0029] The working principle and usage process of the utility model are as follows: when it is necessary to unlock the first joint 1 and the second joint 2, first take the eccentric handle 9 out of the adapter groove 10, and the eccentric rotation of the eccentric handle 9 at the swivel 11 can drive the inner locking connecting rod 12 to move to a certain extent, so that the inner locking block 13 can be easily released from the internal locking with the first clamping part 3 and the second clamping part 4, and then press the lower side of the outer locking pressing block 7. The pressing of the outer locking pressing block 7 will drive the extension and contraction of the spring 8, and at the same time, the clamping part above the outer locking pressing block 7 is tilted through the rotation fulcrum of the outer locking pressing block 7 and the connecting block 6, thereby releasing the external clamping with the first clamping part 3. During this period, the unlocking method of the outer locking pressing block 7 by rotating the fulcrum based on the lever principle is more labor-saving and can release the lock more easily.
