[0002] Existing computer maintenance personnel usually use a workbench when repairing computers. However, when the existing workbench is suitable for computer maintenance, there is a lack of a device for fixing the chassis. The other hand fixes the chassis to prevent it from shifting while the other hand performs maintenance activities, which will cause some inconvenience to the staff's work.

[0003] The existing patent document with publication number CN219854096U discloses a clamping device for computer maintenance, including a movable seat, a side wall of which is welded and fixed with a vertical groove, and the vertical groove is provided with a clamping mechanism; the clamping mechanism includes a load-bearing screw block, the inner side of which is meshed with a screw rod, and the screw rod is rotatably installed on the inner side of the vertical groove.

[0004] The above equipment has the following problems when in use:

[0005] This type of clamping only clamps the bottom of the chassis, and the torque is not balanced. When the upper part of the chassis is subjected to external force, the chassis is prone to shaking, affecting the normal operation of the chassis. In addition, the longitudinal activity curve of the chassis is not restricted, and the clamping is not sufficient.

[0006] For this reason, we propose a computer maintenance clamping and fixing device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figures 1 to 6A clamping and fixing device for computer maintenance includes a mounting frame 1, a receiving chamber 2 is rotatably mounted on the mounting frame 1, a bidirectional threaded rod 3 is rotatably mounted inside the receiving chamber 2, a rotating disk 9 is fixedly mounted on the bidirectional threaded rod 3 through the receiving chamber 2, and the bidirectional threaded rod 3 can be driven to rotate by rotating the rotating disk 9;

[0032] Two nut pairs 8 are connected to the bidirectional threaded rod 3 by threads, and connecting rods 10 are fixedly installed on the nut pairs 8, and clamping blocks 11 are fixedly installed on the two connecting rods 10;

[0033] The rotation of the bidirectional threaded rod 3 causes the two nut pairs 8 to move toward or away from each other synchronously, and then the connecting rod 10 and the clamping block 11 move synchronously. The clamping block 11 can clamp both sides of the chassis to be repaired placed inside the accommodating chamber 2.

[0034] A lead screw 14 is rotatably mounted inside the clamping block 11, and the lead screw 14 is threadedly connected to a lead screw nut 17, and an L-shaped edge pressing block 18 is fixedly mounted on the lead screw nut 17;

[0035] By rotating the lead screw 14, the lead screw nut 17 can drive the L-shaped edge clamping block 18 to move synchronously, so that the L-shaped edge clamping block 18 is in contact with the outer wall and the inner wall of the chassis at the same time, thereby further ensuring the stability of clamping.

[0036] The lead screw 14 passes through the clamping block 11 and is fixedly mounted with an extension rod 15 , on which a hexagonal screw hole 16 is provided.

[0037] The extension rod 15 can be rotated by the lead screw 14 . By inserting a tool of corresponding diameter into the hexagonal screw hole 16 , the extension rod 15 can be rotated, and then the lead screw 14 can be rotated.

[0038] Elastic pads 13 are embedded and installed on the two clamping blocks 11. The two elastic pads 13 are located on the side of the clamping block 11 away from the accommodating chamber 2. The elastic pads 13 protect the chassis through their own deformation to avoid scratches.

[0039] The two connecting rods 10 are respectively fixedly mounted with a hollow plate 7 and a backing plate 12 . The backing plate 12 is located inside the hollow plate 7 and can slide inside the hollow plate 7 .

[0040] When the two connecting rods 10 are close to each other, the backing plate 12 also slides inside the hollow plate 7, and the length of the whole formed by the two will also change.

[0041] When the L-shaped edge clamping block 18 contacts the outer wall and the inner wall of the chassis at the same time, the L-shaped edge clamping block 18 continues to move, and the chassis will move synchronously. By making the back of the chassis directly contact the hollow plate 7 and the back plate 12, multi-directional clamping and fixing activities can be achieved.

[0042] A fixing cylinder 19 is fixedly installed on the accommodating chamber 2, and a fixing rod 21 is fixedly installed at the center of the fixing cylinder 19. The fixing cylinder 19 is rotated by the fixing rod 21, and the accommodating chamber 2 can rotate synchronously, thereby realizing the change of the chassis angle, which is convenient for maintenance activities.

[0043] A fixed block 23 is fixedly mounted on the fixed cylinder 19 , a spring 27 is fixedly mounted inside the fixed block 23 , a moving block 24 is fixedly mounted on the other end of the spring 27 , and a gear block 25 is fixedly mounted on the moving block 24 .

[0044] A semicircular mounting member 20 is fixedly mounted on the mounting frame 1 , and a semicircular internal gear 22 is fixedly mounted inside the semicircular mounting member 20 . The semicircular internal gear 22 is matched with the gear block 25 .

[0045] When the semicircular internal gear 22 is in contact with the tooth block 25, the fixed cylinder 19 cannot rotate due to the meshing relationship, and the accommodating chamber 2 is stably maintained at a certain specific angle. When adjustment is required, it is only necessary to move the moving block 24 inside the fixed block 23 to disengage the semicircular internal gear 22 from the tooth block 25, and then the angle adjustment can be performed.

[0046] A moving rod 26 is fixedly mounted on the moving block 24 , and a sliding groove for the moving rod 26 to slide is provided on the fixed block 23 .

[0047] By moving the moving rod 26 closer to the fixed rod 21 , the semicircular internal gear 22 and the gear block 25 can be separated.

[0048] When no external force is applied, the semicircular internal gear 22 and the gear block 25 can be in contact with each other due to the presence of the spring 27 .

[0049] A fixing plate 5 is fixedly mounted on the mounting frame 1, and a storage box 6 is slidably mounted on the fixing plate 5. The storage box 6 can be used to place accessories required for maintenance and parts removed from the equipment to avoid loss.

[0050] An adjustable lamp 4 is slidably mounted on the receiving chamber 2 .

[0051] The working process of the utility model is to place the chassis to be repaired inside the storage chamber 2, turn the turntable 9, and the bidirectional threaded rod 3 rotates. The rotation of the bidirectional threaded rod 3 makes the two nut pairs 8 move synchronously closer to or away from each other, and then the connecting rod 10 and the clamping block 11 move synchronously. The clamping block 11 can clamp the two sides of the chassis to be repaired placed inside the storage chamber 2.

[0052] After the elastic pad 13 on the clamping block 11 contacts the edge of the chassis, a tool of corresponding diameter is inserted into the hexagonal screw hole 16 to rotate the extension rod 15 and move the L-shaped edge pressing block 18.

[0053] When the L-shaped edge clamping block 18 contacts the outer wall and the inner wall of the chassis at the same time, the L-shaped edge clamping block 18 continues to move, and the chassis will move synchronously. By making the back of the chassis directly contact the hollow plate 7 and the back plate 12, multi-directional clamping and fixing activities can be achieved.

[0054] When the angle needs to be adjusted, the semicircular internal gear 22 and the gear block 25 can be separated by moving the moving rod 26 closer to the fixed rod 21. At this time, the fixed cylinder 19 is rotated to a corresponding angle, and the angle of the accommodating chamber 2 is changed accordingly.

[0055] When no external force is applied, the semicircular internal gear 22 and the tooth block 25 can be in contact due to the presence of the spring 27. Due to the meshing relationship, the fixed cylinder 19 cannot rotate, and the accommodating chamber 2 is stably maintained at a certain angle.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
