Description

One kind is without screw designs cabinet self-locking device

Technical field

Machine box for server technique for fixing field is the utility model is related to, the specific one kind that provides is without screw designs cabinet self-locking Device.

Background technology

Computer has the advantages that information memory capacity is big, and user's acquisition information is convenient and swift, is widely applied.Machine Case is the important component of computer, is the carrier of computer major part part, the fastness of cabinet fastening is for computer Normal operation there is extremely important effect.Along with the development of information technology, military computer, server and peripheral hardware etc. are more Come it is more be applied in the various adverse circumstances such as vehicle-mounted, carrier-borne, higher reliability requirement and maintainability requirement, for such The fastening means of military terminal proposes higher requirement, and the cabinet fastening means thus without screw/few screw is arisen at the historic moment.So And traditional no screw/few screw designs, it is difficult to take into account attractive in appearance and reliability, often size is big, complicated, machinability Difference, need further to be improved.

The content of the invention

In order to solve the problem present on, the utility model provides a kind of structure design advantages of simple, can guarantee that cabinet Fixed fastness, at the same can take into account cabinet aesthetic property without screw designs cabinet self-locking device.

To achieve the above object, the utility model provides following technical scheme：

One kind is without screw designs cabinet self-locking device, including some self-locking pins, some fixed parts and some springs, institute State that the quantity of self-locking pin is equal with the quantity of fixed part, and self-locking pin is made up of locating rod and two spacing balls, two spacing Ball is separately fixed at locating rod both ends, and the diameter of spacing ball is more than the size of locating rod；The fixed part is separately fixed at cabinet Top, the position corresponding with fixed part offers fixing hole on chassis lid；The longitudinal section of the fixed part is in n fonts, fixed Through hole is offered in portion, the wherein shape of upper through-hole is engaged with the shape of locating rod, and lower through-hole is rectangle, and bottom The size of through hole is more than the diameter of the spacing ball at self-locking pin both ends；The spring fixes enclosure top respectively.

The spring is spring structure of the prior art.

It is during use, the fixing hole on chassis lid is corresponding with the fixed part on cabinet, chassis lid is placed on machine On case, chassis lid is pressed, spring is in compressive state, now, the spacing ball of self-locking pin one end is passed through into fixed part bottom Through hole passes completely through the through hole of fixed part, and come up chassis lid, and spring promotes chassis lid to move up, and chassis lid promotes self-locking The locating rod of pin is slipped into fixed part upper through-hole, and that realizes self-locking pin enters position automatically.Due to the diameter of two spacing balls More than the size of locating rod, that is to say, that the diameter of spacing ball is more than the size of upper through-hole, and the spacing ball at both ends can be realized The stop of self-locking pin horizontal direction and anticreep, so as to which chassis lid is firmly fixed on cabinet.Due to the presence of spring, make Positions stem segment derived from lock pin can bear 2.5Kg power, so as to effectively avoid self-locking pin in vibratory impulse environment from taking off The possibility fallen, improve the reliability of self-locking pin.

Preferably, the locating rod is trapezoidal, the shape of fixed part upper through-hole is engaged with locating rod, described trapezoidal The fastness that structure can strengthen the locating rod of self-locking pin and upper through-hole is combined.

Preferably, the quantity of the self-locking pin is 4-6.

Preferably, the locating rod of the self-locking pin is structure as a whole with spacing ball, the firm of self-locking pin is strengthened Property.

Preferably, the quantity of the spring is 4-6.

Compared with prior art, no screw designs cabinet self-locking device of the present utility model has following prominent beneficial Effect：

（One）The locating rod of the self-locking pin is trapezium structure, and fixed part upper through-hole is to be engaged with positional lever structure It is trapezoidal, can realize after self-locking pin is fitted into fixed part and slip into automatically in upper through-hole, it is easy for installation, be firmly combined with；

（Two）Self-locking pin both ends are designed using spacing ball, can realize stop and the anticreep of self-locking pin horizontal direction, So as to which chassis lid is firmly fixed on cabinet；

（Three）Spring design on cabinet so that the positions stem segment of self-locking pin can bear 2.5Kg power, so as to effectively The reliability for avoiding the possibility that self-locking pin comes off in vibratory impulse environment, improving self-locking pin.
