DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0027] The embodiment of the present application provides a collision-resistant computer expansion card, which solves the problem that traditional computer expansion cards are generally fixed to the chassis by a plate on the expansion card, thereby fixing the expansion card. However, the expansion card is usually not protected on the outside and is easily damaged by collision with tools during the installation of other equipment or subsequent maintenance of the computer. In addition, the expansion card is fixed in a single manner and may become loose or detached.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] The utility model embodiment discloses an anti-collision computer expansion card. Figure 1-5 As shown, it includes an expansion card body 1 and a fixing plate 101 fixedly connected to the expansion card body 1, the fixing plate 101 is fixed to the chassis body 2, and an anti-collision mechanism is provided on the expansion card body 1, and the anti-collision mechanism includes:

[0030] The first card connection rail 3 is arranged on the expansion card body 1;

[0031] The bearing block 4 is movably connected to the first card rail 3;

[0032] An anti-collision frame 5 is arranged on the bearing block 4;

[0033] A second card rail 6 is movably connected to the bearing block 4, and the second card rail 6 is fixedly connected to the chassis body 2;

[0034] The positioning assembly is arranged on the bearing block 4 , and is used to lock the positions of the bearing block 4 and the second card rail 6 .

[0035] The positioning assembly includes a sleeve 7 fixedly connected to the bearing block 4, a slider 701 is slidably connected inside the sleeve 7, and a positioning pin 702 is fixedly connected to the slider 701;

[0036] A locking hole 601 is provided on the second card rail 6, and the positioning pin 702 is movably engaged in the locking hole 601. The structural design of the positioning component is simple, and the positioning component can be used to conveniently fix the position of the supporting block 4 and the first card rail 3. It is only necessary to engage the positioning pin 702 in the locking hole 601.

[0037] Furthermore, a screw rod 703 is threadedly connected to the sleeve 7, and the screw rod 703 is rotatably connected to the slider 701. A rotating handle is provided on the screw rod 703. The screw rod 703 is convenient for adjusting the position of the slider 701, and then the position of the positioning pin 702 is adjusted, making the positioning assembly easy to operate.

[0038] The supporting block 4 is provided with a first clamping strip 401 for clamping the first clamping rail 3, and the supporting block 4 is provided with a second clamping strip 402 for clamping the second clamping rail 6.

[0039] The anti-collision computer expansion card is convenient for installing the expansion card body 1 in position when in use. First, the fixing plate 101 is connected and fixed to the chassis body 2, and then the anti-collision frame 5 and the bearing block 4 are installed to provide anti-collision protection for the expansion card body 1, thereby ensuring good stability of the expansion card body 1.

[0040] When installing the anti-collision mechanism on the expansion card body 1, the operation is simple and convenient, saving time and effort. During the operation:

[0041] Firstly, align the first card strip 401 and the second card strip 402 with the inside of the first card connection rail 3 and the second card connection rail 6 respectively for insertion;

[0042] When the first card strip 401 and the second card strip 402 are completely inserted into the first card connection rail 3 and the second card connection rail 6, the anti-collision frame 5 forms an outer protection for the expansion card body 1;

[0043] Finally, the positioning assembly is used to fix the positions of the carrier block 4 and the first connecting rail 3 . During operation, the screw rod 703 is directly rotated. The screw rod 703 pushes the slider 701 and the positioning pin 702 to move, and the positioning pin 702 is inserted into the lock hole 601 .

[0044] The anti-collision mechanism of the device has a compact overall structure. It not only protects the outer side of the expansion card body 1 with the anti-collision frame 5, but also reinforces the fixation of the expansion card body 1 on the chassis body 2 through the card connection and positioning design of the first card connection rail 3, the second card connection rail 6 and the carrier block 4, thereby ensuring the stability of the force on the expansion card body 1.
