Description

Hard disk bracket and pull-out assisting handle thereof

Technical Field

The utility model relates to the technical field of server equipment, in particular to a hard disk bracket and a pull-out assisting handle thereof.

Background

The hard disk bracket is generally installed inside the case for installing the hard disk. The hard disk bracket is mainly used for extracting the hard disk from the hard disk bin or sending the hard disk into the hard disk bin.

At present, a pull-assisting handle is generally arranged at one end of the hard disk bracket and is used for facilitating the insertion and the pull-out of the hard disk bracket. The pull-assist handle typically effects unlocking of the handle by depressing the lock. But current press lock generally includes button, pendulum structure and buckle, and pendulum structure and buckle all set up in the bottom of button along the direction of pressing of button, can make the buckle rotate when pressing the button to make buckle release handle. The pendulum structure is used for preventing the key from being separated.

Due to the arrangement of the pendulum structure and the buckle, the thickness of the sliding lock along the pressing direction of the key is larger, the occupied space is larger, and therefore the utilization rate of the internal space of the server is lower.

Disclosure of Invention

Accordingly, it is necessary to provide a hard disk bracket and a pull-up grip thereof, which solve the problem that the conventional pull-up grip has a large thickness in the pressing direction of a key.

The pulling-assisting handle comprises a base, a handle, a pressing component and a sliding component;

When the hard disk bracket is not required to be plugged in or pulled out, the pulling-assisting handle can be closed, and at the moment, the pulling-assisting handle only occupies a small space in the case.

In this embodiment, referring to fig. 2, the first direction OX may be a length direction of the base 100, and the second direction OY is a depth direction of the accommodating cavity 110, that is, a pressing direction of the pressing assembly 300. The pressing assembly 300 is movably connected to the base 100 along the second direction OY, that is, when the pressing assembly 300 is pressed along the second direction OY, the pressing assembly 300 can move along the second direction OY to push the sliding assembly 400 along the first direction OX, and when the sliding assembly 400 moves, the engaging portion 421 on the sliding assembly 400 can be disengaged from the fastening portion 210 on the handle 200, so that the handle 200 is opened. That is, by means of the arrangement of the sliding block 420 assembly, the pushing force of the pressing assembly 300 along the second direction OY can be directly converted into the first direction OX, and the sliding assembly 400 slides along the first direction OX to unlock the handle 200, so that other structures are not required to be arranged at the bottom of the pressing assembly 300 along the pressing direction, and the thickness of the pulling-assisting handle along the second direction OY can be effectively reduced.

Further, referring to fig. 1, 3 and 5, one end of the handle 200 is pivoted to the base 100 through a second pivot structure 220, the second pivot structure 220 includes a second pin 221 and a second torsion spring 222, the second torsion spring 222 is sleeved on the second pin 221, the second torsion spring 222 is in a V-shaped structure, one end of the second torsion spring 222 is hooked with the base 100, and the other end of the second torsion spring 222 is abutted with the handle 200. Referring to fig. 1, when the engaging portion 421 is engaged with the fastening portion 210, the handle 200 is closed, and the first end and the second end of the second torsion spring 222 are close to each other, so that the second torsion spring 222 is in a force storage state.

The pull-assist handle as set forth in claim 1, wherein the sliding assembly comprises a link and a slider, a first end of the link being rotatably connected to a side of the pressing assembly within the receiving cavity, a second end of the link being rotatably connected to the slider, the mating portion being disposed on the slider;

when the pressing component moves, the first end of the connecting rod can be pushed to rotate along the second direction, so that the second end of the connecting rod drives the sliding block to move along the first direction.

3. The assist handle as set forth in claim 2, wherein the first end of the link is located on a side of the second end adjacent the handle in the second direction when the handle is in the locked condition.

4. The pull-assist handle as set forth in claim 2, wherein the latch is located at a side of the handle adjacent to the accommodating cavity, a latch groove is formed between the latch and the handle, and an opening direction of the latch groove faces the slider.

5. The assist grip of claim 1, wherein the slide assembly further comprises a first elastic member disposed on a side of the slide assembly away from the pressing assembly, one end of the first elastic member in a first direction abutting the base, and the other end of the first elastic member in the first direction abutting the slide assembly.

6. The pull-assist handle of claim 1 wherein the pressing assembly is located at the other end of the handle in the first direction, the pressing assembly comprising a first pivot structure and a key, the end of the key remote from the handle being pivotally connected to the base by the first pivot structure.

7. The pull-assist handle of claim 6 wherein the first pivot structure comprises a first torsion spring and a first pin, the first torsion spring is sleeved on the first pin, one end of the first torsion spring abuts against the key, and the other end of the first torsion spring is fixed with the base.

8. The pull-assist handle of claim 1 wherein the base is provided with a stop portion, an end of the stop portion remote from the base having an arcuate surface for mating with an end of the pressing assembly proximate to the handle.

9. The pull-assist handle as set forth in claim 1, wherein a first abutment is provided at an end of the handle pivotally connected to the base, the first abutment being adapted to abut against the chassis to form a lever structure having a contact point between the first abutment and the chassis as a fulcrum;

and/or, one end of the handle pivoted with the base is provided with a second abutting part, the second abutting part is mutually spaced from the first abutting part and is positioned on one side of the first abutting part, which is close to the base, and the second abutting part is used for abutting with the case so as to form a lever structure taking the contact point of the second abutting part and the case as a fulcrum.

10. A hard disk carrier, comprising a carrier body and the pull-up assisting handle according to any one of claims 1 to 9, wherein the pull-up assisting handle is provided at one end of the carrier body.
