The working principle of the utility model is as follows:
In this embodiment, referring to fig. 1 to 6, the process of implementing the mounting-free process of the rear bracket of the slide rail is as follows: the rear support of the slide rail is required to be matched and fixed with the mounting holes on the two sides of the server rack, so that the follow-up working flow is ensured.
When the rear support of the sliding rail is installed, as the fixing frame 201 at the tail end of the support head 2 is fixedly connected with the outer rail 1 of the sliding rail support, the convex hulls 203 exist at the limiting positions of the end operating plates 202 in the support head 2, the positions of the convex hulls 203 can limit the positions of the elastic scissor clamping structures 3, the through holes 206 for the front claw plates 307 of the scissor plates 301 to pass through are formed in the front bending plates 204 of the support head 2, and accordingly the elastic scissor clamping structures 3 can be matched with the installation holes on the basis of the support head 2.
A reset pressure spring 306 is arranged in the spring mounting opening 304, two ends of the reset pressure spring 306 are wound around the two spring mounting protrusions 305, when the first leading-in inclined surfaces 308 of the two scissor plates 301 are pinched, the two scissor plates 301 are moved close to each other under the action of the reset pressure spring 306 (meanwhile, the restoring force of the elastic scissor clamping structure 3 is prepared), at the moment, when the elastic scissor clamping structure 3 is compared with an initial state, the sectional area is reduced, and then the sectional area of the elastic scissor clamping structure 3 can enter the mounting hole.
The process that the elastic scissors clamping structure 3 gets into the mounting hole is, pinch two first leading-in inclined planes 308 after, make the mounting hole can slide into the mounting hole through first leading-in inclined planes 308, then loosen two first leading-in inclined planes 308, the elastic scissors clamping structure 3 resumes its initial condition under the effect of pressure spring 306 that resets this moment, and the mounting hole is limited by first joint groove 309, be formed with a semicircular recess between first leading-in inclined planes 308 and the first joint groove 309, this semicircular recess can firm fixed mounting hole, meanwhile, the location guide pillar 205 of bending plate 204 front end also joint is to the mounting hole in, and semicircular recess and location guide pillar 205 are at the coplanar, support mounting is accomplished behind the slide rail this moment.
Preferably, the positioning guide column 205 can be screwed out from the threaded hole on the bending plate 204, so that the positioning guide column 205 can be replaced according to the size of the mounting hole, so that the mounting hole with different sizes can be adapted, and when the diameter of the mounting hole is overlarge, the mounting hole can enter the second clamping groove 311 through the second guiding inclined plane 310, and the semicircular recess formed between the second clamping groove 311 and the first guiding inclined plane 308 can fix the mounting hole with overlarge diameter.
When the rear bracket needs to be disassembled, the two first leading-in inclined planes 308 are pinched first, so that the sectional area of the elastic scissor clamping structure 3 is reduced, the semicircular recess is relieved from being contacted with the mounting hole, the elastic scissor clamping structure 3 can be pulled out from the mounting hole, and meanwhile, the positioning guide posts 205 can be separated from the mounting hole, and the rear bracket of the sliding rail is disassembled.
Since the height of the via 206 is higher than the height of the elastic scissor clamping structure 3, and the width of the via 206 contacts one side of the two claw hook plates 307, the elastic scissor clamping structure 3 can limit the initial state of the elastic scissor clamping structure 3 in the via 206, and can generate two states of stress and unstressed.
When the elastic scissor holding structure 3 is stressed, the two scissor plates 301 mirror-image each other, one side of the two claw hook plates 307 is away from both sides (width direction) of the inner edge of the via hole 206, and the two spring mounting projections 305 are close to each other.
When the elastic scissor holding structure 3 is not stressed, a gap exists between the two claw hook plates 307, and one side of the two claw hook plates 307 is in contact with both sides (width direction) of the inner edge of the via hole 206, and a gap also exists between the two spring mounting protrusions 305.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
