Description

A tool-less backplane mount

technical field

The utility model relates to the technical field of computers, in particular to a tool-free backboard installation device with simple structure.

Background technique

Traditional server hard disk backplane structures are fixed by screws, which requires a screwdriver to install or remove. The production efficiency is low, and as the depth of the server case becomes shorter and shorter, the interior of the case becomes more and more compact, and the distance between the fan and the hard disk backplane is continuously reduced. It is very inconvenient to use a screwdriver to install and remove the screws near the bottom and sides of the chassis, which brings great inconvenience to the production and customer service personnel in maintaining the backplane. Therefore, it is very necessary to improve the usability of the backplane. Based on this, a tool-free server hard disk backplane installation structure is now provided.

Contents of the invention

The technical task of the utility model is to solve the deficiencies of the prior art, and provide a tool-free backboard installation device with simple structure and ideal use effect.

The technical scheme of the utility model is realized in the following manner, a tool-free backboard installation device, the structure of which includes a hard disk backplane and a chassis, the hard disk backplane is provided with guide holes and limit holes, and a through hole is installed on the hard disk backplane. The spring plunger passing through the hard disk backplane is respectively used in conjunction with the guide hole, the limit hole and the spring plunger. The chassis is provided with a guide post, a limit plate and a fixing hole.

Through the above-mentioned structural settings, the hard disk backplane is guided through the cooperation of the guide hole, that is, the guide column, during installation, and the limit plate is inserted into the limit hole to complete the limit of the hard disk backplane. The plunger completes the limit in the up and down direction, and the whole process does not need to install any screws, which realizes tool-free installation; in addition, the spring plunger can use the common plunger in the prior art, that is, when the top of the spring plunger is bent to 90 degrees , the column is exposed and fixed in the fixing hole, and the column is retracted when it is bent to 180 degrees, so that the column is separated from the fixing hole.

Preferably, the guide hole is in the shape of a gourd with a small upper part and a large gourd at the lower part. Correspondingly, the guide post is in the shape of a stepped column with a small inside and a large outside. The inner diameter of the guide post is smaller than the minimum diameter of the guide hole, and the outer diameter is larger than the guide hole. The minimum diameter of the guide hole is smaller than the maximum diameter of the pilot hole. The guide column is T-shaped. After being installed in the guide hole, the stepped T-shaped nail can play a guiding role, ensuring that the limit hole and the limit plate correspond accurately during installation.

Preferably, the limiting hole is composed of two long holes with a small top and a large bottom, and the two long holes are connected to each other, and the corresponding limiting plate is in the shape of an "L" plate with an upward opening. The limiting hole is in the shape of a wine bottle, and the limiting plate is in the shape of a hook. During actual installation, the limiting plate of the chassis goes deep into the wider part of the bottom. The upper part of the hole is narrower, so as to fix the front, rear and left and right directions of the hard disk backplane.

Further, there are 2N symmetrically opened guide holes and limiting holes, correspondingly, 2N symmetrically opened guide posts and limiting plates, and N is a natural number greater than or equal to 1. This structure can firmly fix the entire case and the hard disk backplane, and has strong practicability.

As a preference, a protruding plate is provided protruding from the upper part of the chassis, and the guide columns are evenly installed on the protruding plate; one side of the protruding plate is extended outwards and provided with a rectangular protruding block, and the limiting plate is vertically arranged on the outer edge of the protruding block place. This structure can be more beneficial to the installation of the hard disk backplane on the chassis, the purpose of the installation is more clear, the installation is fast, and the efficiency is high.

In summary, the beneficial effects produced by the utility model compared with the prior art are:

A tool-free backboard installation device of the utility model has the characteristics of simple structure, convenient use, and novel concept. The installation process does not require the use of screwdrivers and screws, and the operation is flexible and convenient. The installation efficiency is high, safe and reliable, and the product quality is effectively improved. , save maintenance time, enhance the company's product competitiveness, strong practicability, wide application range, and easy promotion.
