Example 3

Referring to Figures 3 and 4, a third embodiment of the present invention is shown. This embodiment provides a microcomputer protection device. The microcomputer protection device includes a locking component 300. Through the locking assembly 300, the back cover 102 and the housing 101 can be tightly connected.

Specifically, it includes a control part 301 and a transmission part 302 arranged on the outer wall of the control part 301. The control part 301 penetrates the casing 101, leaving the main control part outside the casing 101 for easy control. The transmission part 302 inside the casing 101 can lock the back cover 102 on the casing 101.

Preferably, the control member 301 includes a control gear 301a. The control gear 301a is provided with a transmission shaft 301b at its axis. The transmission shaft 301b penetrates to the outer wall of the housing 101 and is sleeved with a knob 301c. The control gear 301a is arranged inside the housing 101, and the knob 301c is arranged outside. A transmission shaft 301b is provided in the middle to connect the two. When the knob 301c is rotated, the transmission shaft 301b drives the control gear 301a to move together.

The transmission member 302 includes a transmission rod 302a. The end of the transmission rod 302a is provided with a rack 302b. The rack 302b meshes with the control gear 301a. The inner wall of the housing 101 is provided with a first fixed base 302c. The first fixed base 302c is movably connected with The transmission rod 302a has a transmission block 302d set at one end of the transmission rod 302a away from the rack 302b. A rack 302b is provided at the end of the transmission rod 302a to mesh with the control gear 301a. A first fixed base 302c is provided in the housing 101. The transmission rod 302a moves in the first fixed base 302c. When the control gear 301a rotates, the rack 302b follows the rotation of the control gear 301a. The control gear 301a rotates together. Since there is a first fixed base 302c outside the transmission rod 302a, the transmission rod 302a moves horizontally. At this time, the transmission rod 302a drives the transmission block 302d at the end to move horizontally.

Preferably, the outer wall of the transmission block 302d is connected to a short transmission rod 302e, and the inner wall of the housing 101 is screwed to a second fixed base 302c-1 and a third fixed base 302c-2. The second fixed base 302c-1 is movable with a corner. The outer wall of the angular moving block 302f is movably connected to the transmission short rod 302e. The outer wall of the angular moving block 302f is connected to a locking rod 302g. The outer wall of the locking rod 302g is movably connected to the third fixed base 302c-2. A transmission short rod 302e is connected to the outer wall of the transmission block 302d. When the transmission rod 302 drives the transmission block 302d to move, the transmission short rod 302e moves together. The other end of the transmission short rod 302e is connected to the angular motion block 302f, and the angular motion block 302f is connected to the angular motion block 302f. The two fixed bases 302c-1 are fixed. When the transmission short rod 302e moves with the transmission block 302d, the angular motion block 302f is driven by the transmission short rod 302e to move together. Since the middle part of the angular motion block 302f is fixed by the second fixed base 302c -1 is fixed, so when the angular motion block 302f is driven by the transmission short rod 302e, the other end makes an up and down reciprocating motion. The other end of the angular motion block 302f is connected to a locking rod 302g, and the locking rod 302g is on the third fixed base. 302c-2 moves, and the locking rod 302g moves up and down along with the movement of the angular moving block 302f.

When in use, turning the knob 301c clockwise drives the control gear 301a to rotate clockwise, and the rack 302b meshing with the control gear 301a also moves in the horizontal direction. The rack 302b drives the transmission rod 302a to move to the left, and the transmission rod The transmission block 302d at the end of 302a also moves horizontally to the left. The transmission short rod 302e hinged on the outer wall of the transmission block 302d pushes the angular movement block 302f. The angular movement block 302f is fixed by the second fixed base 302c-1, so the angle is fixed. The other end of the block 302f is pushed upward, driving the locking rod 302g to move upward. At this time, the locking rod 302g can pass through the second limiting hole 102a-1 and enter the first limiting hole 101a to fix the back cover 102 to the housing. 101, counterclockwise rotation will cause the locking lever 302g to move downward, causing the back cover 102 to separate from the housing 101.

Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the present utility model can be modified.
