[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides an anti-theft computer case, including a mounting frame 1, two support frames 7 are fixedly installed on the top of the mounting frame 1 by bolts, a case body 8 is fixedly installed between the tops of the two support frames 7, an insertion slot 10 is provided on one side of the outer wall of the case body 8, a side cover 11 is movably inserted on the inner surface wall of the insertion slot 10, a square slot 14 is provided on one side of the outer wall of the case body 8, a protective cover 15 is fixedly installed on the inner surface wall of the square slot 14 by bolts, an installation box 16 is fixedly installed on the inner surface wall of the square slot 14, a compression spring 17 is fixedly installed on one side of the inner wall of the installation box 16, and an outer wall side of the compression spring 17 is electrically connected to the power supply inside the case body 8, and the outer wall side of the compression spring 17 is fixedly installed There is a conductive column 18, a first pole piece 19 is fixedly installed on one side of the inner wall of the installation box 16, a limit rod 20 is movably embedded in the inner wall of the square groove 14, a movable column 21 is movably inserted into the inner wall of the square groove 14, a fixed box 22 is fixedly installed on the inner wall of the square groove 14, a limit spring 23 is fixedly installed on one side of the inner wall of the fixed box 22, a conductive block 24 is fixedly installed on one side of the outer wall of the limit spring 23, a second pole piece 25 is fixedly installed on one side of the inner wall of the fixed box 22, and one side of the outer wall of the second pole piece 25 is electrically connected to one side of the outer wall of the first pole piece 19, a second alarm light 26 is fixedly installed on one side of the outer wall of the chassis body 8, and the input end of the second alarm light 26 is electrically connected to one side of the outer wall of the limit spring 23.

[0024] The effect achieved by the entire embodiment 1 is that when the computer case is in normal use, the conductive column 18 is in contact with the first pole piece 19. Since the side cover 11 is inserted into the insertion slot 10, the top rod installed on the outer wall side of the conductive block 24 will exert an extrusion force, resulting in the conductive block 24 not being in contact with the second pole piece 25, so the second alarm light 26 will not sound an alarm. When someone violently disassembles the side cover 11 of the case body 8, the side cover 11 is taken out from the insertion slot 10, so that the top rod on the outer wall side of the conductive block 24 loses the extrusion force, and the conductive block 24 will be in contact with the second pole piece 25 under the action of the limit spring 23, so that the circuit is closed, and the second alarm light 26 will sound an alarm to remind the surrounding The security personnel around the computer case can protect the computer case. When the case body 8 needs to be opened normally, the key of a specific size must be inserted into the movable column 21 under the operation of the staff, and then the movable column 21 is rotated to a certain angle. Since the outer wall of the movable column 21 is equipped with a convex block, the limit rod 20 will be lifted up during rotation, so that the limit rod 20 moves to one side inside the square groove 14, thereby pushing the conductive column 18 to move to one side inside the installation box 16, so that it does not contact the first pole piece 19, thereby disconnecting the circuit, and finally taking out the side cover 11. The second alarm light 26 will not alarm, so that the staff can repair the electronic components inside the case easily.

[0025] Embodiment 2, as Figure 2-Figure 4 As shown, a mounting groove 2 is provided at the top of the mounting frame 1, a negative electrode sheet 3 is fixedly installed on one side of the inner wall of the mounting groove 2, a positive electrode sheet 4 is fixedly installed on one side of the inner wall of the mounting groove 2, a battery 5 is arranged inside the mounting groove 2, and the positive and negative electrodes of the battery 5 are in contact with the positive electrode sheet 4 and the negative electrode sheet 3 respectively, a first alarm light 6 is fixedly installed at the top of the mounting frame 1, and the input end of the first alarm light 6 is electrically connected to one side of the outer wall of the positive electrode sheet 4, and the output end of the first alarm light 6 is electrically connected to one side of the outer wall of the negative electrode sheet 3, an insulating sheet 9 is fixedly installed at the bottom of the chassis body 8, and two threaded grooves 12 are provided on the outer wall of the side cover 11, and threaded rods 13 are movably inserted into the inner walls of the two threaded grooves 12.

[0026] The effect achieved by the entire embodiment 2 is that when the computer case needs to be installed, the case body 8 can first be installed on a higher wall under the action of the mounting frame 1 and the bolts, so that the case body 8 will not be easily stolen. At the same time, under the action of the support frame 7 and the bolts, the case body 8 can be firmly fixed to the top of the mounting frame 1. When the case body 8 is in normal use, due to the action of the insulating sheet 9, the battery 5, the negative electrode sheet 3, the positive electrode sheet 4 and the first alarm light 6 do not form a closed circuit, and the use of the first alarm light 6 will not sound an alarm. When someone steals the case body 8, since the insulating sheet 9 is fixedly connected to the case body 8, when the case body 8 is stolen, the insulating sheet 9 will be taken out from between the battery 5 and the positive electrode sheet 4, and the battery 5 will contact the positive electrode sheet 4, so that the circuit is closed, which will cause the first alarm light 6 to alarm and remind the security personnel, thereby protecting the computer case.

[0027] Working principle: When the computer case needs to be installed during use, the case body 8 can first be installed on a higher wall under the action of the mounting frame 1 and the bolts, so that the case body 8 will not be easily stolen. At the same time, under the action of the support frame 7 and the bolts, the case body 8 can be firmly fixed to the top of the mounting frame 1. When the computer case is in normal use, the conductive column 18 is in contact with the first pole piece 19. Since the side cover 11 is inserted into the insertion slot 10, the top rod installed on the outer wall side of the conductive block 24 will exert an extrusion force, resulting in the conductive block 24 not contacting the second pole piece 25, so the second alarm light 26 will not sound an alarm. When someone violently disassembles the side cover 11 of the case body 8, the side cover 11 is removed from the insertion slot 10, so that the top rod on the outer wall side of the conductive block 24 loses the extrusion force, and the conductive block 24 will be in contact with the second pole piece 25 under the action of the limit spring 23, so that the circuit is closed, and the second alarm light 26 will sound an alarm to alert the surrounding security guards. Personnel, thereby protecting the electronic components inside the computer case. When someone steals the entire case, since the insulating sheet 9 is fixedly connected to the case body 8, when the case body 8 is stolen, the insulating sheet 9 will be taken out from between the battery 5 and the positive electrode sheet 4, and the battery 5 will contact the positive electrode sheet 4, so that the circuit is closed, which will cause the first alarm light 6 to alarm and remind the security personnel. When it is necessary to open the case body 8 normally for maintenance, it is first necessary to use a key of a specific specification and size to insert it into the inside of the movable column 21 under the operation of the staff, and then rotate it to a certain angle. Since the outer wall of the movable column 21 is equipped with a convex block, it will lift the limit rod 20 during rotation, so that the limit rod 20 moves to one side inside the square groove 14, thereby pushing the conductive column 18 to move to one side inside the installation box 16, so that it does not contact the first electrode sheet 19, thereby disconnecting the circuit, and finally taking out the side cover 11. The second alarm light 26 will not alarm, and then the electronic components inside the computer case are repaired.

[0028] The chassis power supply, compression spring 17, conductive column 18, first pole piece 19, second pole piece 25, conductive block 24, limit spring 23 and second alarm light 26 in the present application, when the chassis side cover 11 is forcibly removed, a closed circuit will be formed to make the second alarm light 26 alarm, and the chassis power supply will be connected to an external power supply separately, and there will be current output when the computer is not in use. At the same time, the above structures can all be conductive, so that the current can pass smoothly. The top rod on one side of the outer wall of the installation box 16, the fixing box 22, the limit rod 20 and the conductive block 24 are all made of insulating material and are not conductive. The circuits involved in the present application can be connected by wires or internal wires, and are common knowledge in the field, and the control method and wiring arrangement will not be explained in detail.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
