The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1 to Figure 3 , which is the first embodiment of the utility model, and this embodiment provides a locking mechanism, including a box body unit 100, including a lower box body 101, and an upper box body 102 connected and matched with the lower box body 101, and the two are rotatably connected;

[0032] The locking unit 200 includes a locking assembly 201 disposed on the front side of the lower box body 101 for connecting with the upper box body 102 , and a clamping assembly 202 disposed on the inner side of the lower box body 101 . The clamping assembly 202 is in contact with the upper box body 102 at the same time.

[0033] Furthermore, optical cable placement grooves 101a are provided on both sides of the lower box body 101, which are semicircular grooves, and two are symmetrically provided on each side for placing cables. A locking groove 101b is vertically opened on the front side plate of the lower box body 101, and locking block grooves 101c are opened on both sides. The front side of the locking block groove 101c passes through the front side plate of the lower box body 101.

[0034] Furthermore, optical cable clamping grooves 102a are provided on both sides of the upper box body 102, which are consistent in shape with the optical cable placement groove 101a and cooperate therewith for placing the cable, and after cooperation, the diameter of the circular hole is consistent with the diameter of the cable sheath, and a clamping plate 102b is provided at the lower end of the front side plate of the upper box body 102, which cooperates with the clamping groove 101b.

[0035] It should be noted that the height of the engaging plate 102b is less than the depth of the engaging groove 101b. When the two are matched, the lower end of the engaging plate 102b is still one to two millimeters away from the lower end of the engaging groove 101b.

[0036] Furthermore, the locking grooves 102b-1 are symmetrically formed on both sides of the locking plate 102b, and the lower side of the locking groove 102b-1 is a first pressing inclined surface 102b-2, which is an inclined surface with an angle less than five degrees.

[0037] Furthermore, the locking assembly 201 includes a locking block 201a arranged in the locking block groove 101c, the upper side of the front end of which is a locking slope 201a-1, and the lower side is a second clamping slope 201a-2, the second clamping slope 201a-2 cooperates with the first clamping slope 102b-2, the angles of the two slopes are consistent, the length of the second clamping slope 201a-2 is shorter than the first clamping slope 102b-2, when the two cooperate, the front side of the locking block 201a extends out of the front side of the locking block 201a with an adjustment block 201a-3, the adjustment block 201a-3 extends out of the front side opening of the locking block groove 101c, the locking assembly 201 also includes a locking block spring 201b connected to the rear end of the locking block 201a, the rear end of which is fixedly connected to the inner wall of the locking block groove 101c.

[0038] When in use, place the optical cable in the optical cable placement groove 101a. After the optical cable is installed and connected, rotate and close the upper box body 102, so that the locking plate 102b enters the locking groove 101b. During the entry process, the lower end of the locking plate 102b first hits the locking inclined surface 201a-1, so that it squeezes the locking block spring 201b to retract into the locking block groove 101c, and continues to close until the upper box body 102 contacts the lower box body 101. At this time, the locking block 201a enters the locking recess The second pressing bevel 201a-2 cooperates with the first pressing bevel 102b-2. Under the action of the locking block spring 201b, the second pressing bevel 201a-2 applies a downward squeezing force to the upper box body 102 and the lower box body 101, so that the connection between the upper box body 102 and the lower box body 101 is tighter. When it is necessary to open, the locking block 201a is disengaged from the locking groove 102b-1 by pushing the adjusting block 201a-3, and the upper box body 102 can be rotated to open.

[0039] In summary, the lower box body 101 and the upper box body 102 are connected by the snap assembly 201, which reduces the steps of bolt disassembly and installation and reduces the workload. At the same time, the snap assembly 201 can provide tightening pressure to the connected box body unit 100 to ensure the sealing of the connection.

[0042] Furthermore, the clamping assembly 202 also includes an adjusting buckle 202b, which is rotatably connected to the upper end of the fixed clamping seat 202a and cooperates with the optical cable fixed clamping groove 202a-1. The two form an optical cable clamping hole to clamp the optical cable. The upper end of the adjusting buckle 202b is rotatably connected to the adjusting rod 202c, and the upper end of the adjusting rod 202c is rotatably connected to the adjusting buckle 202d. The adjusting buckle 202d is rotatably connected to the left and right adjusting rods 202c. By pulling the adjusting buckle 202d up and down, the opening and closing states of the left and right adjusting buckles 202b can be synchronously adjusted.

[0043] Furthermore, a limiting pressure groove 202d-1 is provided at the upper end of the adjusting buckle 202d, which is an arc groove. A limiting pressure block 102c is provided at the corresponding position of the limiting pressure groove 202d-1 on the upper box body 102. The two cooperate to limit the state of the adjusting buckle 202d. When the adjusting buckle 202d makes the adjusting pressure buckle 202b completely closed, the limiting pressure block 102c can just cooperate with the limiting pressure groove 202d-1.

[0044] During use, when the optical cable needs to be installed, the adjusting buckle 202d is pulled up, and the adjusting pressure buckle 202b is opened under the drive of the adjusting rod 202c, and the optical cable is placed in the optical cable fixed clamping groove 202a-1, and then the adjusting buckle 202d is pressed down to close the adjusting pressure buckle 202b, and the optical cable is stably clamped by the clamping protrusion 202a-2. After completing the optical cable connection work, the upper box body 102 is closed, and the limiting pressure block 102c cooperates with the limiting pressure groove 202d-1 to limit it.

[0045] In summary, connecting the optical cable through the clamping assembly 202 is convenient and quick, and provides additional clamping force for the optical cable, making its connection more stable. Thanks to the setting of the limiting pressure block 102c, the clamping assembly 202 will not fall off after installation.
