After the surface of the external connection body 5 is stably combined with at least one sliding seat 2, the pulling body 31 of the pulling assembly 3 can be pulled upwards to be in an open state, so that the abutting surface 314 of the pulling body 31 abuts against and is supported on the surface of the base 21 of the sliding seat 2, thus preventing the excessive pulling from losing the supporting force, and then the pulling body is held on the pulling part 313 of the pulling body 31 or the surface of the external connection body 5, so that the external connection body 5 is downwards placed in the accommodating space 40 of the external base body 4, at this time, the guiding piece 32 of the pulling assembly 3 is guided by the guiding surface 111 at the top of the guiding channel 11 of the guiding seat 1, so that the guiding piece 32 smoothly enters the guiding channel 11, and then the pulling body 31 of the pulling assembly 3 can be downwards rotated, the pulling body 31 can be anticlockwise rotated by using the shaft column 34 as the axis, at this time, the guiding rod 321 of the guiding piece 32 can vertically slide downwards in the guiding channel 11, the roller 322 pivoted on one side of the guide rod 321 will rotate in the guide channel 11 to improve the smoothness during sliding, and in the process of the guide member 32 sliding vertically downward in the guide channel 11, the sliding seat 2 and the external combination 5 will be linked to move backward in the horizontal direction, at the same time, the first abutting portion 352 and the second abutting portion 353 on both sides of the torsion spring 35 will be pressed by the bottom surface of the base 311 of the pulling body 31 and the surface of the base 21 to be a compression deformation, and the fixed column 332 of the fixed member 33 will enter the sliding slot 231 of the positioning portion 23 and will be guided along the guiding inclined surface 2311 opened by the sliding slot 231 to move, and in the process of the fixed column 332 moving along the guiding inclined surface 2311, the two ends of the fixed column 332 will slide in the two sliding holes 3122, and the fixed column 332 will stretch the hooking portion 3331 at one end of the elastic element 333 outward to make the elastic element 333 in a stretching state, when the pulling body 31 is continuously pulled downwards until the fixing post 332 is not in contact with the guiding slope 2311 of the sliding slot 231, the elastic element 333 is elastically restored, and the fixing post 332 is pulled back and positioned in the positioning slot 232 at the bottom of the sliding slot 231, so that the pulling body 31 of the pulling assembly 3 is in a locked state, and the external combination body 5 is stably positioned in the accommodating space 40 of the external base 4 after being horizontally moved backwards.
However, if the pulling body 31 of the pulling assembly 3 is opened to extract the external combination 5, the pushing plate 3311 of the pushing block 331 of the fixing member 33 is pushed backward to displace the fixing post 332 backward, so that the fixing post 332 is separated from the limit of the positioning slot 232 of the positioning portion 23 and is in an unlocked state, and then the pulling portion 313 of the pulling body 31 is pulled upward to rotate the pulling body 31 clockwise, and the guiding member 32 of the pulling assembly 3 slides vertically upward in the guiding channel 11 of the guiding base 1, so that the sliding base 2 and the external combination 5 are moved horizontally forward, and the fixing post 332 vertically moves upward in the sliding slot 231 of the positioning portion 23, at this time, the pulling body 31 can be directly extracted upward, so that the guiding member 32 of the pulling assembly 3 is separated from the guiding channel 11 of the guiding base 1, and the external combination 5 can be taken out of the receiving space 40 of the external portion 4, thus completing the assembly and use of the present invention.
The sliding seat 2 is preferably locked and positioned on the surface of the external combination body 5, but in practical applications, it can be riveted or SMT and the like to the external combination body 5, however, there are many ways to combine the sliding seat 2 and the external combination body 5, so the structure for achieving the above effects should be covered by the present invention, and such simple modifications and equivalent structural changes should be included in the scope of the present invention as well as it is obvious.
Furthermore, when the pulling assembly 3 is in the open state, the distance between the shaft post 34 of the pulling assembly 3 and the guiding member 32 minus the distance between the shaft post 34 and the guiding channel 11 of the guiding seat 1 can obtain the displacement distance of the sliding seat 2 driven by the pulling assembly 3 when the pulling assembly 3 is in the locked state, and if the displacement distance of the sliding seat 2 needs to be changed, the distance between the shaft post 34 and the guiding member 32 needs to be increased or decreased.
However, the external base 4 can be other objects for accommodating and containing, such as a server case, a computer host, a storage or telecommunication cabinet, and the external combination 5 can be an object for installing on the external base 4, such as a server hard disk, an optical disk drive, a recorder, or a circuit board.
In addition, the above-mentioned external base 4 is preferably equipped with the guide seat 1 on the side wall surface to provide the sliding of the guide member 32 of the pulling assembly 3, but in practical application, the side wall surface of the external base 4 can also be directly stamped to form the shape of the guide channel 11 of the guide seat 1, however, there are many ways to form the guide channel 11 of the guide seat 1 on the side wall surface of the external base 4, so the structure capable of achieving the above-mentioned effects should be covered by the present invention, and such simple modification and equivalent structural changes should be included in the patent scope of the present invention as well as it is obvious.
Referring to fig. 8 and 10, it is seen that the cross-sectional side view (iv) of the present invention and the cross-sectional side view of the other embodiment are taken, but in practice, the guide channel 11 of the guide base 1 of the present invention is cut vertically downward, but in the other embodiment of the present invention, the guide channel 11 of the guide base 1 is curved, when the wrench body 31 of the wrench assembly 3 is wrenched downward, the guide member 32 of the wrench assembly 3 slides along the curved guide channel 11, and the sliding base 2 moves forward and backward along the shape of the guide channel 11, so that the outer assembly 5 can move in different directions according to the shape of the guide channel 11.
The invention has the following advantages:
when the pulling body 31 of the pulling assembly 3 is pulled, the guiding member 32 can be used to guide the sliding in the guiding channel 11 of the guiding seat 1 to move the sliding seat 2 in the other direction relative to the sliding of the guiding member 32, and after the pulling body 31 of the pulling assembly 3 is pulled, the sliding seat can be positioned on the positioning portion 23 of the sliding seat 2 by the fixing member 33 of the pulling assembly 3, so that the pulling assembly 3 is in a locked state, thus, the complicated assembling actions such as locking by using screws and the like are not needed, the difficulty of the whole operation can be reduced, and the effect of improving the speed of the whole assembly can be achieved.
Secondly, when the pulling body 31 of the pulling assembly 3 is pulled downwards, the fixing member 33 directly positions the fixing post 332 in the positioning slot 232 of the positioning portion 23 of the sliding seat 2 to be in the locking state through the elastic element 333, so that the pulling assembly 3 can be directly in the locking state by using the one-time pulling-downwards action without additional locking action, thereby the operation is simple and the assembling speed of the whole operation can be increased.
Third, when the pulling body 31 of the pulling assembly 3 is in the open state, the pulling body 31 is supported on the surface of the base 21 of the sliding seat 2 by the supporting surface 314 to prevent over-pulling and losing the supporting force, thereby preventing the outer assembly 5 from shaking and swaying during the assembly process, so that the guiding member 32 of the pulling assembly 3 can be accurately installed in the guiding channel 11 of the guiding seat 1, and thus improving the accuracy and stability during the assembly process.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
