[0007] The fixed shaft is arranged on the threaded column; the guide screw passes through the limit seat, and the guide screw is threadedly connected to the threaded column;

[0008] A workpiece is arranged between the fixing plate and the threaded column. A mounting hole is provided at the edge of the workpiece, and the mounting hole is fitted with the side wall of the fixing shaft.

[0009] Furthermore, the limit seat is provided with a 90° tapered hole;

[0010] The guide screw is a countersunk screw, and the guide screw includes a head structure, and the head structure extends into the 90° tapered hole.

[0011] Furthermore, the guide screw is a captive screw.

[0019] Furthermore, the workpiece is a solid state disk.

[0020] The present invention provides a guide, limit, and fixing device comprising a limit seat, a guide screw, and a threaded post. The limit seat comprises a fixed plate and a fixed shaft connected to each other. The fixed shaft is mounted on the threaded post. The guide screw passes through the limit seat and is threadedly connected to the threaded post. A workpiece is positioned between the fixed plate and the threaded post.

[0027] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0028] The present invention provides a guide, limit, and fixation device. The following provides a plurality of embodiments to describe the guide, limit, and fixation device provided by the present invention in detail.

[0029] The guide limit fixing device provided in this embodiment is as follows: Figures 1 to 4 As shown, it includes a limit seat 1, a guide screw 2 and a threaded column 41; the limit seat 1 includes a fixed plate 11 and a fixed shaft 12 connected to each other; the fixed shaft 12 is set on the threaded column 41; the guide screw 2 passes through the limit seat 1, and the guide screw 2 is threadedly connected to the threaded column 41; the workpiece 5 is set between the fixed plate 11 and the threaded column 41, and the edge of the workpiece 5 is provided with a mounting hole 51, and the mounting hole 51 is in contact with the side wall of the fixed shaft 12.

[0030] like Figure 3 As shown, the fixed plate 11 is disposed above the fixed shaft 12, with the outer edge of the fixed plate 11 located outside the outer edge of the fixed shaft 12, and the fixed plate 11 and the fixed shaft 12 are fixed as one body. The fixed shaft 12 is disposed on a threaded post 41, and the workpiece 5 is disposed between the top surfaces of the fixed plate 11 and the threaded post 41. The mounting hole 51 of the workpiece 5 is aligned with the side wall of the fixed shaft 12. After the guide screw 2 passes through the limit seat 1, the guide screw 2 is threadedly connected to the threaded post 41, so that the limit seat 1 is fixed to the threaded post 41. At this time, the fixed plate 11 and the threaded post 41 cooperate to clamp the workpiece 5, so that the workpiece 5 is fixedly mounted between the limit seat 1 and the threaded post 41.

[0031] The mounting hole 51 is provided at the edge of the workpiece 5 , and the mounting hole 51 penetrates the edge of the workpiece 5 , thereby forming an opening at the edge of the workpiece 5 , and the fixing shaft 12 extends into the mounting hole 51 through the opening.

[0032] In a vibration and impact environment, when the workpiece 5 is about to deviate horizontally toward the fixed shaft 12, the fixed shaft 12 can support the workpiece 5 and limit the workpiece 5, thereby preventing the workpiece 5 from deviating horizontally and enabling the workpiece 5 to be accurately fixed and positioned. When the workpiece 5 is a solid state disk 3, the solid state disk 3 maintains good contact, thereby realizing the storage and retrieval functions well.

[0033] Furthermore, the limiting seat 1 is provided with a 90° tapered hole; the guide screw 2 is a countersunk screw, and the guide screw 2 includes a head structure 21, and the head structure 21 extends into the 90° tapered hole.

[0034] The head structure 21 extends into the 90° tapered hole, and the shape of the head structure 21 is adapted to the shape of the 90° tapered hole. The 90° tapered hole has a centering function, so that the guide screw 2 is coaxial with the 90° tapered hole, which plays a guiding role in the installation of the guide screw 2.

[0035] Furthermore, the mounting hole 51 is semicircular and the fixed shaft 12 is cylindrical. The mounting hole 51 fits with the fixed shaft 12 so that the mounting hole 51 and the limiting seat 1 are coaxially arranged.

[0036] By fitting the mounting hole 51 with the fixed shaft 12 and extending the head structure 21 into the 90° tapered hole, the mounting hole 51, the guide screw 2 and the 90° tapered hole are coaxial, thereby ensuring accurate installation of the workpiece 5 and reducing horizontal installation errors.

[0037] Furthermore, the guide screw 2 is a captive screw.

[0038] The guide screw 2 is a captive screw. After the guide screw 2 is matched with the limit seat 1, the guide screw 2 is not easy to fall off from the limit seat 1. The installation is flexible, so that the guide screw 2 and the limit seat 1 are matched to form a component, and together realize the guiding, limiting and fixing function of the workpiece 5.

[0039] Furthermore, the limit seat 1 is also provided with a threaded hole, and the 90° tapered hole is connected to the threaded hole; the guide screw 2 also includes a smooth rod 22 and a threaded rod 23, and the head structure 21, the smooth rod 22 and the threaded rod 23 are connected in sequence; the threaded rod 23 passes through the 90° tapered hole and the threaded hole in sequence, and the threaded rod 23 is threadedly connected to the threaded column 41.

[0040] The head structure 21, polished rod 22, and threaded rod 23 are sequentially fixedly connected to form the guide screw 2. The 90° tapered hole, threaded hole, and threaded column 41 are coaxially arranged, with the 90° tapered hole positioned above the threaded hole. After the threaded rod 23 passes through the 90° tapered hole, it can be threadedly connected to the threaded hole. The threaded rod 23 can rotate within the threaded hole. After the threaded rod 23 is screwed out of the threaded hole, the polished rod 22 enters the threaded hole. The polished rod 22 is spaced apart from the threaded hole, and the threads of the threaded rod 23 can abut against the bottom opening of the threaded hole, thereby preventing the guide screw 2 from falling out of the limit seat 1.

[0041] After the threaded rod 23 is threadedly connected to the threaded column 41 , the limiting seat 1 and the threaded column 41 can be fixed.

[0042] Furthermore, the fixing plate 11 is disc-shaped. The radius of the fixing plate 11 is larger than the radius of the fixing shaft 12, so that the fixing plate 11 and the threaded column 41 cooperate to clamp the workpiece 5. The dimensions of the fixing plate 11 and the fixing shaft 12 are designed according to the dimensions of the mounting hole 51.

[0043] The fixed disk 11 and the fixed shaft 12 can be fixed together by a fixed connection, or can be an integrated structure.

[0044] Furthermore, the guide, limit and fixation device further includes a base plate 4 , and the threaded column 41 is fixedly arranged on the base plate 4 .

[0045] The threaded column 41 can be fixedly connected to the base plate 4 or can be an integral structure with the base plate 4 .

[0046] The workpiece 5 may be a workpiece 5 with a mounting hole 51 provided on any edge thereof. In this embodiment, the workpiece 5 is a solid state disk 3 .

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
