As shown in fig. 1-3, the utility model provides a computer mainframe box, include:

the side surface of the chassis shell is open, two first screw holes are formed in the vertical edge, close to the open side surface, of the tail panel 1 of the chassis shell, and the two first screw holes are respectively close to the upper end and the lower end of the tail panel 1 of the chassis shell;

the side cover plate comprises a first plate body 2 and a second plate body 3 which are vertically connected with each other, the first plate body 2 covers the open side face of the chassis shell, the second plate body 3 covers the vertical edge surface of the tail panel 1 of the chassis shell close to the open side face, the second plate body 3 just faces two first screw holes and is recessed towards the direction far away from the tail panel 1 of the chassis shell to form a circular groove 4, the groove 4 is coaxial with the first screw hole just facing the groove 4, the inner diameter of the groove 4 is larger than the major diameter of the first screw hole, a through hole coaxial with the groove 4 is formed in the bottom of the groove 4, and the diameter of the through hole is smaller than the minor diameter of the first screw hole;

anticreep screw, it includes:

the diameter of the connecting shaft 5 is slightly smaller than that of the through hole, the connecting shaft 5 penetrates through the through hole, and the length value of the connecting shaft 5 is larger than the sum of the depth value of the groove 4 and the thickness value of the first plate body 2;

the nail head 6 is cylindrical, a first thread is arranged on the circumferential surface of the nail head 6, so that the nail head 6 is in threaded connection with the first screw hole, the length of the nail head 6 is the same as the depth of the groove 4, and the nail head 6 is coaxially connected to one end, close to the tail panel 1 of the chassis shell, of the connecting shaft 5;

the nail cap 7 is cylindrical, the diameter of the nail cap 7 is larger than that of the through hole, and the nail cap 7 is coaxially connected to one end, far away from the tail panel 1 of the chassis shell, of the connecting shaft 5;

and one end of the spring 8 abuts against the surface of the nail cap 7 connected with the connecting shaft 5, the other end of the spring 8 abuts against the back of the bottom of the groove 4, the spring 8 is wound on the connecting shaft 5, when the spring 8 is in a free state, the nail head 6 is arranged in the groove 4, and when the spring 8 is in a compressed state, the nail head 6 is in threaded connection with the first screw hole.

In the use process of the embodiment, if the side cover plate and the chassis shell need to be assembled together, only the nail head 6 of the anti-falling screw needs to be aligned to the first screw hole, a little pressure is applied to the nail cap 7, so that the first screw of the nail head 6 is buckled into the first screw hole, then the nail cap 7 is rotated to enable the nail head 6 to completely enter the first screw hole, and at the moment, the spring 8 is in a compressed state; if the side cover plate needs to be detached from the chassis shell, only a little pressure needs to be applied to the nail cap 7, after the frictional resistance between the nail head 6 and the first screw hole is reduced, the nail cap 7 is rotated to enable the nail head 6 to completely return to the groove 4, and at the moment, the spring 8 is in a free state. Because the side shroud is dismantled from chassis exterior after, because the anticreep screw is fixed on second plate body 3, so can remove along with the side shroud, do not worry that the anticreep screw is lost because of placing improperly, simultaneously, because be equipped with spring 8 between the back of nut 7 and recess 4, so when the anticreep screw back of unscrewing under the elastic force effect nut 7 can evaginate rapidly, the user can know the screw at once and unscrew need not twisting, and when the anticreep screw back of screwing, the elasticity that spring 8 produced also makes frictional force increase between pin head 6 and the first screw, connect more firmly.

In another embodiment, the edge of the surface of the nail head 6 connected with the connecting shaft 5 is coaxially connected with an annular baffle plate 9, the outer diameter of the annular baffle plate 9 is smaller than the inner diameter of the groove 4, and the outer diameter of the annular baffle plate 9 is larger than the small diameter of the first screw hole, so that after the nail head 6 completely enters the first screw hole, the annular baffle plate 9 cannot continue to advance due to abutting against the tail panel 1 of the case shell, and the nail head 6 is prevented from penetrating out of the first screw hole to cause connection failure and permanent damage to the spring 8.

In another embodiment, the connection manner of the nail cap 7 and the connection shaft 5 is as follows: the one end that connecting axle 5 kept away from chassis exterior's afterbody panel 1 is provided with the second screw, the terminal surface of nail cap 7 seted up with second screw assorted second screw, nail cap 7 with connecting axle 5 threaded connection, anticreep screw is installed on second plate body 3 more easily like this, if the condition of the smooth silk of pin fin 6 appears simultaneously, more conveniently with pin fin 6 and the separation of nail cap 7 change.

In another embodiment, a plurality of anti-slip grooves are uniformly arranged on the circumferential surface of the nail cap 7 along the axial direction, so that a user can not slip when screwing the nail cap 7, and the use is more labor-saving.

In another embodiment, the four corners of the bottom of the case shell are provided with rollers, so that a user can conveniently move the computer case.

In another embodiment, the top of the case shell is provided with a handle, and because the existing computer case is not provided with a handle, when the computer breaks down and needs to be sent to a maintenance point for maintenance, the computer case is inconvenient to carry, and a user can transport the computer case more comfortably by arranging the handle.

While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
