Description

Improved HDD extraction structure

The utility model relates to an installation structure of an electronic computer hard disk, in particular to an installation structure of a movable hard disk.

The birth of the computer can be said to be the greatest product of this century, and the circulation of the personal computer has brought the functions of the computer into full play. In today's industry, commerce and various service industries, it is a mature operation method to use computers to process various affairs. Even ordinary household computer users use computer networks to communicate information or shop, etc. It is a global trend.

In a computer, the hard disk and the floppy disk each provide the necessary data for the operation of the computer, especially the amount of data that the hard disk can store and the computing power are unmatched by the floppy disk, so its status in a computer is like The heart is just as important. Nowadays, the hard disk devices of personal computers can be divided into two types: fixed hard disks installed inside the host computer and movable (extractable) hard disks that can be drawn out from the mainframe at any time. Confidential information is stored inside or a huge database that needs to be accessed anywhere, with the convenience and safety features of being portable.

The movable hard disk generally has two devices, one is the hard disk box 10, and the other is the support frame 11 of the hard disk box, wherein the support frame 11 is fixed on the structure of the host computer 12, and the two are attached to the end of the hard disk box. The plug 13 is combined with the socket 14 of the supporting frame (as shown in FIG. 1 ). Movable hard disk is owing to provide the function that can arbitrarily extract or insert, so the probability that hard disk case enters and exits in support frame just increases greatly, and this will make the plug that is divided into hard disk case and support frame, easy to wear and tear. In fact, the natural wear and tear caused by the extraction and insertion of general plugs and sockets is very small, but the unbalanced wear is mainly caused by improper human operation. In severe cases, it may even cause distortion and deformation of the terminals in the plugs and sockets.

Improper wear and tear of plugs and seats caused by humans is mainly due to improper force applied during extraction and insertion. Generally, when extracting or inserting the hard disk box on the support frame, the magnitude of the applied force and the angle of extraction often vary from person to person. However, the plug and the seat cannot properly adjust the joint angle or the combined force according to different users. This is the reason why the plug and the seat are abnormally worn. Worn or abnormally worn plugs and sockets will make the hard disk in an extremely unstable state of use, and at the same time will cause the hard disk to transmit and process data incorrectly, resulting in a great risk of data loss.

The purpose of this utility model is to provide a suitable extraction device, which can eliminate human improper operation factors, and achieve normal extraction and insertion actions to eliminate abnormal wear of plugs and seats caused by human factors, and then prolong the life of the product. and stability.

In order to achieve the above purpose, a number of embedded notches are made at the handle shaft of the hard disk box, and matching retaining angles and folded edges are set at the entrance of the hard disk support frame. When using the rack, the handle of the hard disk box must be turned into a horizontal state to push the hard disk box into the support frame, and when the handle is turned down to a vertical state, the hard disk box will be automatically inserted into the support frame in a balanced manner. In addition, when the handle is pulled back to the horizontal state, the hard disk box can be automatically separated from the plug and seat of the supporting frame in a balanced manner, so that the hard disk box can be safely extracted. In this way, a smooth and balanced insertion and removal of the hard disk box can be achieved, and damage to the hard disk caused by improper insertion and withdrawal of the hard disk box can be prevented.

The utility model is completed in this way, which is characterized in that the left and right shaft ends of the handle of the hard disk box are made into an arc-shaped end, and the arc-shaped end is provided with an arc-shaped notch and a straight-line notch longitudinally along the side bar of the handle. The mouth is horizontally placed on both sides of the side lever of the handle to form a relative state, a buckle part is formed between the two notches, and the opening end of the hard disk support frame forms a folded piece, which is screwed at a small distance from the folded piece to form a T shape. block, so that the distance between the flap and the T-shaped block forms a card notch, and the outermost end of the T-shaped block faces an inverted L-shaped retaining angle toward the inner side of the support frame.

The length of the flap is slightly shorter than the longitudinal length of the straight notch.

Compared with the prior art, the utility model has the advantages that a corresponding positioning structure is provided on the hard disk box and the supporting frame, which completely avoids damage to the hard disk caused by abnormal insertion and extraction of the hard disk box. Greatly prolong the service life of the active hard disk.

The accompanying drawings are further described in conjunction with the embodiments

Fig. 2 is a perspective view of the structural part of the utility model. The handle 2 at the front end of the hard disk 10 of the present utility model is wider than the body of the hard disk box 10, and the rotating shaft part protruding outside the hard disk body forms an arc-shaped end 20, and the arc-shaped end 20 is longitudinally provided with an arc-shaped recess along the handle side bar 24. The mouth 21 and the linear notch 22 form a buckle portion 23 at the position sandwiched by the two notches 21 and 22 . On the other hand, the open end of the hard disk supporting frame 11 forms an L-shaped flap 110 whose length is slightly shorter than the longitudinal length of the straight notch 22 . In addition, a T-shaped block 3 is screwed outward from the folded piece 110 at a short interval, so that a card notch 4 is formed between the T-shaped block 3 and the folded piece 110 . The upper end of the outermost end surface of the T-shaped block 3 forms an inverted L-shaped retaining angle 30 toward the inner side plate of the support frame.

See Fig. 3-9, the device has the hard disk box 10 of the utility model handle, when the hard disk box 10 is put into the support frame 11, the handle 2 must be turned upwards to be horizontal, and just can be from the bottom of the retaining angle 30 of the T-shaped block 3 into the support frame 11. Otherwise, if the handle 2 is vertical or non-horizontal, the linear notch 22 will be blocked by the T-shaped block angle 30 and the hard disk box 10 cannot enter. The orientation of the hard disk enclosure 10 causes uneven application of force. After the hard disk case 10 enters the support frame 11 smoothly, the arc-shaped end 20 of the handle will be blocked by the flap 110. At this time, the plug 100 of the hard disk case 10 is not yet combined with the socket 111 of the support frame. This is blocked by the flap 110. The arc-shaped end 20 of the handle makes it impossible to insert the hard disk box 10 temporarily. The purpose is to reduce the force of pushing the hard disk box into it, so that the action of inserting can be temporarily buffered, so as to prevent the plug and seat from being damaged by excessive force. Or cause serious wear and tear on the plug and seat. After the action of pushing into the hard disk box is temporarily blocked, as long as the handle 2 is turned downwards to be in a vertical state, while turning, the arc-shaped end 20 of the handle is gradually separated from the flap 110 to block the hard disk 10 to be pushed forward, so that both The plug, the seat 100 and 111 gradually come into contact, and finally at the moment when the buckle part 23 of the handle is inserted into the notch 4 from bottom to top, the plug, the seat 100 and 110 are also automatically engaged in a balanced manner, and the hard disk box 10 and the supporting frame are completed. 11 full combinations. This kind of mode that the hard disk box 10 is automatically combined with the supporting frame 11 by turning the handle 2 downwards is aimed at eliminating the damage caused to the plug and the seat by combining the plug and the seat with a non-standard artificial force action. Possible damage and improper wear.

The above-mentioned selection of turning the handle 2 horizontally or vertically puts the hard disk box 10 into the support frame 11 safely and smoothly, and the handle in the final state is that the buckle part 23 is snapped into the card notch 4 and the flap 110 Interlocking with the straight notch 22 will make the hard disk 10 be locked in the supporting frame 11 . The correct way to take out the hard disk box of the utility model is to turn the handle 2 upwards into a horizontal state, so that the original upward arc-shaped end 20 will be turned downwards and touch the top flap 110, and the strength of the top flap 110 produces a The reaction force pushes the hard disk box 10 out of the supporting frame 11 for a short distance d in a balanced and smooth manner. This distance d just makes the plugs and seats 100 and 111 of the hard disk box 10 and the supporting frame 11 engaged with each other separate from each other until the plugs and seats start to contact. state, at this moment the hard disk case 10 and the supporting frame 11 are not connected to each other, and the hard disk case 10 can be easily extracted. The design of turning the handle 2 to allow the hard disk box 10 to retreat automatically for a short distance in a balanced manner prevents improper wear of the joint head due to artificial uneven force when the hard disk box 10 is extracted.

In summary, the utility model is based on the arc-shaped end 20, the arc-shaped and straight line notches 21 and 22, and the flap 110 and T-shaped block 3 at the opening of the support frame 11 at the end of the handle shaft. , so that the hard disk box 10 can be smoothly inserted into or drawn out of the support frame 11 by turning the handle horizontally or vertically, and the plugs, seats 13 and 14 of the hard disk box 10 and the support frame 11 can be combined at normal angles, Avoid unbalanced wear of the plug and seat, which will cause the instability of the hard disk.
