Description

The Improved Structure of the Handle of the Computer Case

technical field

The utility model relates to an improved structure of a case handle of communication and control equipment, in particular to an improved structure of a computer case handle.

Background technique

Today, with the rapid development of information technology, computers are inseparable from people's work and life. Although the notebook computer is easy to carry, its price is relatively high, which is difficult for ordinary consumers to accept, while the desktop computer has become the first choice of ordinary consumers because of its low price and high quality.

It is possible to move the computer case when repairing the computer mainframe, requiring large-capacity resource exchange, increasing the internal hardware of the mainframe, or moving. However, the desktop computer case is mostly a vertical box design, and its Most of the surrounding sides are flat or slightly curved metal plate surface, which cannot provide force application parts that can be grasped or hand-carried. When moving the case, you can only hold the bottom of the case with both hands as the force application point. This is quite inconvenient when moving the case, and because the bottom surface of the computer case is mostly in contact with the ground and is dirty, it is easier to stain the clothes. In addition, the case must be tilted to one side before the hand is inserted into the bottom during the moving operation. In the process of tilting, sometimes the chassis may be toppled so as to damage the accessories in the chassis, which increases the unsafety of the chassis in the process of moving.

Therefore, some people directly add handles on the computer case in a one-piece molding or locking manner. Although this improvement to the case solves the above-mentioned deficiencies to a certain extent, due to such a protruding handle, it will inevitably increase the number of handles on the upper part of the case. The space of the computer case makes the entire computer case higher and more abrupt, and the placement area of the case must also consider the height of the protruding part of the handle. Therefore, someone has designed a computer case with a rotatable handle (similar to the handle of a general suitcase). Vibration or vibration is large, which may cause cracks, damage and deformation of the shaft hole where the pivot is installed, and may also cause deformation and damage to the pivot of the handle. In the computer case, the external force generated by the computer case will swing relative to the pivot of the handle, and even if the external force factor is too large, the swing amplitude and frequency will be increased, which will more easily loosen the boards in the case and cause the hard disk to be scratched. It may also cause inconvenience for the user to walk when the chassis is shaking, or cause injury to the limbs when they are touched.

Utility model content

In order to overcome the above-mentioned defects, the utility model proposes an improved structure of a computer case handle.

The technical solution adopted by the utility model for solving the above-mentioned technical problems is: an improved structure of a handle of a computer case, comprising: a main body of the computer case, an upper cover panel and a rotating handle, and the rotating handle passes through the pivots at both ends of the handle and The pivot holes on the upper cover panel are pivotally connected and placed in the concave hole of the upper cover panel. It is characterized in that: the rotating handles are a pair of handles. The pair of handles produces an engaging device for synchronous lifting and releasing actions.

In the improved structure of the handle of the computer case described in the utility model, the said meshing device is a gear meshing structure.

In the improved structure of the handle of the computer case described in the utility model, the said engaging device may be an engaging structure composed of two cylinders with a plurality of protrusions and grooves alternately distributed on the surface of the cylinder, and said two cylinders The bumps and grooves on the cylindrical surface of the body just match up.

In the improved structure of the handle of the computer case in the utility model, the engaging device can also be an engaging structure formed by close contact of two cylindrical bodies with friction surfaces made of a material with a high friction coefficient.

The utility model has the advantages that: the improved structure of the handle of the computer case described in the utility model has four pivots in a pair of handles, so four pivots will be applied to disperse and balance the entire Therefore, the handle is not easily deformed and damaged because of the downward pull force it bears to disperse and reduce; and because the pair of handle pivot ends are provided with an engaging device, it only needs to be lifted or laid flat. With only one handle, the other handle is also lifted or flattened correspondingly, which is convenient for the user to carry out the operation; and the pair of handles of the computer case with handles and the upper cover panel have four pivotal structures, Moreover, each handle can only rotate 90 degrees relative to the upper cover panel, and the two handles restrict each other to offset the lateral force caused by the swing of the chassis. Compared with the hand, the swing of the computer case is relatively small, and can reduce the range of the swing of the human wrist, which can avoid damage to the human limbs and meet the ergonomic requirements. Looseness of the board and accidental damage to the hard disk; in addition, when the handle is not in use, it can be placed in the groove of the upper cover panel without affecting the placement of the computer case.
