Detailed Description

Referring to fig. 1, in a preferred embodiment of the present invention, a locking mechanism 100 includes a locking assembly 10 and a locking portion 50 that can be locked in the locking assembly 10.

The locking assembly 10 includes a base plate 20 and two locking members 30 slidably mounted on the base plate 20. The base plate 20 is provided with a chute 21 for receiving the locking member 30. Each sliding slot 21 includes two parallel first sides 211 and two parallel second sides 212, and the first sides 211 and the second sides 212 are perpendicular to each other. Each first side 211 is provided with a limiting plate 25, and a limiting block 251 is convexly provided at the middle position of the limiting plate 25 towards the direction of the sliding chute 21.

The locking member 30 includes a base 31 and a locking plate 35 fixedly connected to the base 31. The base 31 includes a supporting plate 32 and two fixing plates 33 vertically connected to both sides of the supporting plate 32. The supporting plate 32 is provided with a pillar 321 (see fig. 3) at a side away from the locking member 30. One end of each fixing plate 33, which is far away from the supporting plate 32, is vertically bent to form a folded edge 331, and the folded edge 331 is accommodated between the two fixing plates 33. The distance between the inner walls of the two fixing plates 33 is substantially equal to the width of the substrate 20. The locking plate 35 is substantially vertically connected to the support plate 32 of the base 31. The end of the locking plate 35 away from the supporting plate 32 is provided with a hook 36, and the hook 36 includes an inclined surface 361 and a stop surface 365 (see fig. 3) substantially perpendicular to the locking plate 35. The locking plate 35 is further provided with a pressing surface 37 at an end thereof adjacent to the supporting plate 32.

The fastening portion 50 includes a body 51 and a fastening block 55 fixedly connected to one end of the body 51. The locking block 55 includes a wide portion 551 and a narrow portion 555, the width of the wide portion 551 is greater than the width of the body 51, and a locking surface 552 is formed on each side of the body 51. The width of the narrow portion 555 is smaller than that of the wide portion 551, and a pushing surface 556 is formed on each side.

Referring to fig. 2 to 4, in assembly, two of the locking members 30 are placed on the substrate 20. The two fixing plates 33 of the locking member 30 are pulled to be elastically deformed, the folded edge 331 of the fixing plate passes through the base plate 20 and is fastened to the bottom end of the base plate 20, and the fixing plates 33 are tightly attached to two side walls of the base plate 20. The upright 321 of the base 31 is received in the sliding groove 21 of the substrate 20 and is received between the two limit plates 25. The upright 321 can slide in the sliding groove 21 to drive the locking member 30 to slide between a first position and a second position. At this time, the two locking members 30 are slidably mounted on the substrate 20, and the assembly of the locking assembly 10 is completed.

Pushing the locking members 30 causes the locking members 30 to move closer together in a first position, and pushing the locking members 30 causes the locking members 30 to move away from each other in a second position. When the locking members 30 are in the first position, the distance between the hooks 36 of the two locking members 30 is smaller than the width of the wide portion 551. When the locking members 30 are in the second position, the distance between the hooks 36 of the two locking members 30 is greater than the width of the wide portion 551.

Referring to fig. 2 to 5, when the fastening portion 50 needs to be fixed in the locking assembly 10, the locking member 30 is pushed to make the locking member 30 in the first position. The locking piece 55 of the locking portion 50 is placed between the locking plates 35 of the two locking members 30. The body 51 of the locking portion 50 is pushed toward the substrate 20, and the pushing surfaces 556 on the two sides of the narrow portion 555 are pressed against the inclined surfaces 361 of the hooks 36. The limit block 251 abuts against the upright column 321 to prevent the locking member 30 from sliding, the locking plate 35 is elastically deformed to allow the locking block 55 to pass through the hook 36 and elastically return, and the stop surface 365 of the hook 36 abuts against the locking surface 552 of the wide portion 551 to prevent the locking portion 50 from disengaging from the locking assembly 10. At this time, the locking portion 50 is fixed to the locking assembly 10.

Referring to fig. 6, when the locking portion 50 needs to be taken out of the locking assembly 10, the body 51 of the locking portion 50 is continuously pushed toward the substrate 20, and the pushing surface 556 of the narrow portion 555 is pressed against the pressing surface 37 of the locking plate 35 to push against the locking plate 35. The two locking plates 35 slide in directions away from each other under the pressing of the fastening block 55. The upright 321 presses the stopper 251 of the stopper plate 25, and the stopper 251 elastically compresses to allow the upright 321 to pass through, so that the locking member 30 slides to the second position. The distance between the hooks 36 is greater than the width of the wide portion 551, and the stop surface 365 of the hook 36 slides out of the catch surface 552 of the wide portion 551. At this time, the locking portion 50 can be taken out of the locking assembly 10.

The locking mechanism 100 of the present invention fastens the fastening portion 50 to the locking assembly 10 through the hook 36 of the locking plate 35, and the fastening block 55 of the fastening portion 50 pushes against the locking plate 35 to separate the hooks 36 from each other, so as to conveniently take out the fastening portion 50.

It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that suitable modifications and variations of the above embodiments are within the scope of the present invention as claimed and disclosed within the spirit and scope of the present invention.
