in a state where the h-shaped nail 16 abuts against the limiting groove 17, as shown in fig. 13, the first inclined surface 161 is tightly coupled to the first groove surface 171, a certain included angle exists between the second inclined surface 162 and the first groove surface 171, the upper surface of the head of the h-shaped nail 16 is tightly coupled to the top surface of the limiting groove 17, because the minimum height h1 of the head of the h-shaped nail 16 is greater than the minimum height h2 of the limiting groove 17, a certain gap exists between the head of the h-shaped nail 16 and the limiting groove 17, and a pushing force is continuously applied to the left side rail 11 or the right side rail 12, and because of the special structure of the h-shaped nail 16, the first inclined surface 161 continuously applies a downward force to the first groove surface 171, so that the coupling between the h-shaped nail 16 and the limiting groove 17 is tighter, and the coupling between the clamping portion 142 and the clamping groove 15 is also tight, the locking groove 15 may be a locking groove 15 provided with an opening 151, or may be a locking groove 15 provided with a stopper 152; in the installation state, a strip or sheet type tool applies a downward force to the fixture block 14, presses the fixture block 14 to be attached to the chassis bottom plate, and pushes the left side rail 11 and the right side rail 12 inwards from two sides, so that the left side rail 11 and the right side rail 12 can be unlocked.
In the embodiment of the present invention, an elastic sheet is disposed on the upper surface of the head portion of the i-shaped nail 16 and/or the first inclined surface 161, and the elastic sheet includes a rubber sheet, a silicon sheet, or a plastic sheet, and is used to increase a friction force between the head portion of the i-shaped nail 16 and the limiting groove 17, so that the i-shaped nail 16 is further tightly coupled with the limiting groove 17, and the elastic sheet can also protect the left side rail 11 and the right side rail 12, and prevent the surfaces of the limiting groove 17 on the left side rail 11 and the right side rail 12 from being excessively worn.
In the embodiment of the present invention, in the installation state of the slide rail 1, the sliding groove 13 may be disposed inside the left side rail 11 and the right side rail 12, the sliding groove 13 may also be disposed above the left side rail 11 and the right side rail 12, the guide rails of the daughter card 18 are correspondingly disposed on the left and right sides or the bottom sides of the daughter card 18, and the installation of the daughter card 18 is realized by cooperating with the sliding groove 13.
In the embodiment of the present invention, as shown in fig. 17, the installation manner of the slide rail assembly structure is as follows: when the assembly is started, the left side rail 11 and the right side rail 12 are pushed from inside to outside until the I-shaped nail 16 is clamped into the limiting groove 17, at this time, the first inclined surface 161 is tightly coupled with the first groove surface 171, a certain included angle is formed between the second inclined surface 162 and the first groove surface 171, and the upper surface of the head of the I-shaped nail 16 is tightly coupled with the top surface of the limiting groove 17; when the i-shaped nail 16 is clamped in the limiting groove 17, the clamping block 14 is installed in the corresponding clamping groove 15, at this time, one end of the supporting portion 141 is connected with the chassis bottom plate, the other end of the supporting portion 141 is in a tilting state, the clamping portion 142 is abutted against the stop block 152, and the left side rail 11 or the right side rail 12 is limited to move in a direction of being separated from the i-shaped nail 16, so that locking is achieved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention should be correspondingly included in the scope of the present invention.
