[0001] The utility model relates to the field of industrial control computer motherboards, in particular to a fixing fixture for repairing industrial control computer motherboards. Background Art

[0002] Industrial control motherboard is a special motherboard mainly used in industrial computers to help process industrial projects. The industrial control motherboard is a card-shaped composite board, which is inlaid with various industrial components and various sockets like commercial motherboards. From the board type, the industrial control motherboard is relatively small, with two or three or four PCL ports, and two or more memory slots. A fixing fixture for repairing an industrial control motherboard is disclosed in the Chinese utility model patent with announcement number CN220260951U. The fixing fixture for repairing an industrial control motherboard avoids unnecessary secondary damage caused by looseness during the repair process, frees the hands of the maintenance personnel, and can reasonably adjust the height and inclination to cope with the height of the maintenance point, so that the personnel can repair the industrial control motherboard in the best state.

[0003] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: a certain number of circuit modules are generally arranged on the back of the industrial computer motherboard. In the above structure, the industrial computer motherboard is placed on a fixed table. When repairing the back, it needs to be disassembled and re-fixed, which makes the operation more complicated. For this reason, we designed a fixing fixture for repairing the industrial computer motherboard. Utility Model Content

[0004] In order to solve the technical problem that an industrial computer motherboard is placed on a fixed table and needs to be disassembled and re-fixed when repairing the back side, which makes the operation more complicated, the utility model provides a fixing fixture for repairing an industrial computer motherboard.

[0005] The utility model adopts the following technical scheme to realize a fixing jig for repairing an industrial computer motherboard, comprising two symmetrically distributed longitudinal frames, a transverse frame being fixed by screws in the middle above the two longitudinal frames, two movable frames being arranged above the transverse frames for sliding left and right, a deflection frame being rotatably installed on the upper inner side of the movable frame, and two fixing plates being arranged on the deflection frames for sliding back and forth, and fixing holes being formed through the fixing plates from top to bottom.

[0006] As a further improvement of the above scheme, guide rails are fixed on the front and rear side surfaces of the transverse frame, and guide sliders are installed on the lower ends of the outward sides of the two mobile frames. The guide sliders are connected to the guide rails for left and right sliding, which facilitates the left and right movement of the mobile frame, and then the distance between the two mobile frames can be changed as needed, which is suitable for fixing motherboards of various sizes;

[0007] The left and right sides of the mobile frame are penetrated to form a slide groove matching the guide rail, and the mobile frame is slidably placed on the guide rail and the longitudinal frame through the slide groove, thereby increasing the contact area and improving the firmness of the vertical installation of the mobile frame.

[0008] As a further improvement of the above scheme, a threaded hole is provided on the upper end surface of the guide slider, and a locking bolt is threadedly connected to the threaded hole. The bottom end of the locking bolt is tightly fitted with the upper surface of the horizontal frame. After the mobile frame is moved to a suitable position, the locking bolt is tightened again to fix the mobile frame, thereby facilitating the adjustment of the position of the mobile frame.

[0009] As a further improvement of the above scheme, adjustment slide holes are formed on the upper and lower sides of the deflection frame, and a movable plate is welded on the upper surface of the fixed plate. The movable plate and the fixed plate are designed to be perpendicular to each other and have a T-shaped structure. The movable plate is slid into the adjustment slide hole, and a fixing screw is provided on the top of the movable plate, and a nut is threadedly connected to the fixing screw. The fixed plate can move back and forth along the adjustment slide hole, thereby changing the distance between the two fixed plates on the same deflection frame. It is suitable for motherboards of various sizes, and the nut can be tightened again after moving to the appropriate position.

[0010] As a further improvement of the above scheme, circular holes are formed on the left and right sides of the upper part of the movable frame, and a deflection shaft is welded on the outward side of the deflection frame. The deflection shaft is rotatably placed in the circular hole and partially passes through the circular hole and is placed outside the circular hole. The deflection shaft is placed outside and is provided with threads and nuts. The nuts are tightly pressed against the outer surface of the movable frame. By changing the degree of compression between the nut and the movable frame, the deflection difficulty of the deflection frame can be changed, so that the deflection frame will not deflect under a certain degree of force, which is convenient for fixing the motherboard on the deflection frame and preventing it from shaking.

[0011] As a further improvement of the above scheme, a screw hole is opened on the top of the movable frame, and the screw hole is connected to the circular hole. A locking bolt 2 is threadedly connected inside the screw hole. The bottom end of the locking bolt 2 is tightly pressed against the outer ring surface of the deflection shaft. The deflection frame can be further fixed by tightening the locking bolt 2 after rotation, thereby improving stability.

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] Example:

[0023] Please combine Figure 1-Figure 4 The present embodiment is a fixing fixture for repairing an industrial computer motherboard, comprising two symmetrically distributed longitudinal frames 1, a transverse frame 2 is fixed with screws in the middle of the two longitudinal frames 1, two movable frames 3 are arranged above the transverse frames 2 for sliding left and right, a deflection frame 4 is rotatably installed on the upper inner side of the movable frames 3, and two fixing plates 5 are arranged on the deflection frames 4 for sliding back and forth, and fixing holes 51 are formed through the fixing plates 5 from top to bottom.

[0024] The front and rear surfaces of the transverse frame 2 are both fixed with guide rails 21, and the lower ends of the two mobile frames 3 facing outward are both installed with guide sliders 31, which are slidably connected to the guide rails 21 to facilitate the left and right movement of the mobile frames 3, and thus the spacing between the two mobile frames 3 can be changed as needed, which is suitable for fixing motherboards of various sizes;

[0025] The left and right sides of the mobile frame 3 are penetrated to form a slide groove matching the guide rail 21. The mobile frame 3 is slidably placed on the guide rail 21 and the longitudinal frame 1 through the slide groove, thereby increasing the contact area and improving the firmness of the vertical installation of the mobile frame 3.

[0026] A threaded hole is provided on the upper end surface of the guide slider 31, and a locking bolt 32 is threadedly connected to the threaded hole. The bottom end of the locking bolt 32 fits tightly with the upper surface of the transverse frame 2. After the mobile frame 3 is moved to a suitable position, the locking bolt 32 is tightened again to fix the mobile frame 3, which facilitates the adjustment of the position of the mobile frame 3.

[0027] Adjustment slide holes 41 are formed through the upper and lower sides of the deflection frame 4, and a movable plate 52 is welded on the upper surface of the fixed plate 5. The movable plate 52 is designed to be perpendicular to the fixed plate 5 and has a T-shaped structure. The movable plate 52 is slidably placed in the adjustment slide hole 41, and a fixing screw 53 is arranged on the top of the movable plate 52, and a nut is threadedly connected on the fixing screw 53. The fixed plate 5 can move forward and backward along the adjustment slide hole 41, thereby changing the distance between the two fixed plates 5 on the same deflection frame 4, which is suitable for motherboards of various sizes, and the nut can be tightened again after moving to the appropriate position.

[0028] Circular holes are formed on the left and right sides of the upper part of the mobile frame 3, and a deflection shaft 6 is welded on the outward side of the deflection frame 4. The deflection shaft 6 is rotatably placed in the circular hole and partially passes through the circular hole and is placed outside the circular hole. The deflection shaft 6 is placed outside and is provided with threads and nuts. The nuts are tightly pressed against the outer surface of the mobile frame 3. By changing the degree of compression between the nut and the mobile frame 3, the deflection difficulty of the deflection frame 4 can be changed, so that the deflection frame 4 will not deflect under a certain degree of force, which is convenient for fixing the motherboard on the deflection frame 4 and preventing it from shaking.

[0029] A screw hole is provided above the movable frame 3, and the screw hole is connected to the circular hole, and a locking bolt 61 is threadedly connected inside the screw hole, and the bottom end of the locking bolt 61 is tightly pressed against the outer ring surface of the deflection shaft 6. After the deflection frame 4 is rotated, the locking bolt 61 is tightened to further fix it, thereby improving stability.

[0030] The implementation principle of a fixing fixture for repairing an industrial computer motherboard in the embodiment of the present application is as follows: in actual use, firstly, the spacing between the two deflection frames 4 and the fixing plates 5 on the deflection frames 4 is adjusted according to the size of the motherboard. Specifically, the locking bolt 32 on the guide slider 31 is loosened, and the mobile frame 3 can be moved left and right at this time, and the deflection frame 4 will move along with it, so that the two fixing plates 5 on the two deflection frames 4 can be placed above the motherboard, that is, the fixing holes 51 on the fixing plates 5 can coincide with the holes at the corners of the motherboard, and then the locking bolt 32 can be tightened to fix the mobile frame 3;

[0031] Then, the fixed plate 5 on the moving deflection frame 4 is positioned so that the distance between the two fixed plates 5 on the same deflection frame 4 is consistent with the distance between the two holes on the same side of the motherboard, and then the nut on the fixing screw 53 is tightened. Then, the motherboard can be placed on the four fixed plates 5, and the holes at the four corners of the motherboard are respectively overlapped with the holes on the four fixed plates 5, and then bolts can be used to fix them.

[0032] After the motherboard is fixed on the four fixing plates 5, the deflection frame 4 can be rotated in any direction by loosening the locking bolt 61. When repairing the back side, it can be rotated 180 degrees and the locking bolt 61 can be tightened again.

[0033] By arranging two sliding mobile frames 3 on the transverse frame 2, a deflection frame 4 is rotatably arranged on the mobile frame 3, and two fixing plates 5 are slidably arranged on the inner side of the deflection frame 4, and the position of the fixing plate 5 can be adjusted as needed, so as to be suitable for fixing motherboards of various sizes;

[0034] The deflection frame 4 is rotatably connected to the mobile frame 3 through the deflection shaft 6, and the deflection shaft 6 is placed outside the mobile frame 3 and is provided with a thread and a nut, and the nut is tightly pressed against the outer surface of the mobile frame 3. By changing the degree of compression between the nut and the mobile frame 3, the deflection shaft 6 can be rotated under certain conditions, and the locking bolt 61 provided can be used to fix it after rotation, thereby facilitating the rotation of the motherboard in any direction, and facilitating the maintenance of the motherboard.

[0035] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
