[0049] How it works

[0050] The movable slider 4 is moved in the directional slide rail 1. When the front top block 2 contacts the lock core assembly 6, the front end surface of the plug connector 603 of the lock core assembly 6 contacts and cooperates with one side of the front top block 2. The front top block 2 pushes the plug connector 603, so that the clamping connector 601 of the lock core assembly 6 exits the avoidance groove 501 of the installation groove 5, and the plug connector 603 of the lock core assembly 6 swings outward to exit the accommodating groove 502. As the movable slider 4 slides, the plug connector 603 of the lock core assembly 6 that swings outward is aligned and clamped with any positioning hole 3, so that the sliding support device realizes the positioning function;

[0051] The movable slider 4 is moved in the directional slide rail 1. When the rear top block 8 contacts the lock core assembly 6, the rear end surface of the card top block 604 of the lock core assembly 6 contacts and cooperates with the top contact slider 803 of the rear top block 8. The top contact slider 803 pushes the card top block 604, so that the card joint 601 of the lock core assembly 6 is inserted into the avoidance groove 501 of the installation groove 5. The plug joint 603 of the lock core assembly 6 swings in and out of the accommodating groove 502. The plug joint 603 of the lock core assembly 6 is not aligned and connected with any positioning hole 3. The movable slider 4 can slide arbitrarily in the directional slide rail 1, so that the sliding support can be smoothly retracted.

[0052] When the plug connector 603 of the lock core assembly 6 swings out of the accommodating groove 502, the top block 604 of the lock core assembly 6 abuts against the rear end of the accommodating groove 502, and the contact head 605 of the lock core assembly 6 abuts against the rear end of the notch of the accommodating groove 502, effectively preventing the lock core assembly 6 from swinging out of the installation groove 5, and effectively improving the stability of the sliding support device during positioning.

The front top block 2 pushes the plug connector 603, so that the clamping connector 601 of the lock core assembly 6 exits the avoidance groove 501 of the installation groove 5, and the plug connector 603 of the lock core assembly 6 swings outward to exit the accommodating groove 502. As the movable slider 4 slides, the plug connector 603 of the lock core assembly 6 that swings outward is aligned and clamped with any positioning hole 3, so that the sliding support device realizes the positioning function;

[0081] The movable slider 4 is moved in the directional slide rail 1. When the rear top block 8 contacts the lock core assembly 6, the rear end surface of the card top block 604 of the lock core assembly 6 contacts and cooperates with the top contact slider 803 of the rear top block 8. The top contact slider 803 pushes the card top block 604, so that the card joint 601 of the lock core assembly 6 is inserted into the avoidance groove 501 of the installation groove 5. The plug joint 603 of the lock core assembly 6 swings in and out of the accommodating groove 502. The plug joint 603 of the lock core assembly 6 is not aligned and connected with any positioning hole 3. The movable slider 4 can slide arbitrarily in the directional slide rail 1, so that the sliding support can be smoothly retracted.

[0082] When the plug connector 603 of the lock core assembly 6 swings out of the accommodating groove 502, the top block 604 of the lock core assembly 6 cooperates with the rear end of the accommodating groove 502, effectively preventing the lock core assembly 6 from swinging out of the installation groove 5, and effectively improving the stability of the sliding support device during positioning.

[0083] Embodiment 6

[0084] like Figure 17-18 As shown, the structures and working principles of the directional slide rail 1, the positioning hole 3, the movable slider 4, the mounting groove 5, the lock core assembly 6, and the elastic member 7 in the sixth embodiment are the same as those in the fifth embodiment, and are not repeated here.

[0085] The difference between the sixth embodiment and the fifth embodiment is that:

[0086] The front top block 2 is an inclined convex column. This arrangement can effectively improve the tightness between the front top block 2 and the directional slide rail 1 and can effectively prevent the front top block 2 from separating from the directional slide rail 1 .

[0087] The rear top block 8 is integrally formed with the directional slide rail 1, which effectively improves the stability of the rear top block 8 when it is in contact. There is no limit baffle 9 on the side of the rear top block 8, which effectively reduces the manufacturing cost. The rear top block 8 is a catheter structure, and one end of the rear top block 8 is in contact with the rear end surface of the plug connector 603, wherein the rear top block 8 contacts the rear end of the plug connector 603 to allow the card connector 601 to swing inward and be inserted into the air avoidance groove 501.

[0088] The examples given in the present invention are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here, and the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
