[0025] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0026] like Figure 1-6As shown in the figure, a bearing transportation tooling in an embodiment of the present utility model is shown, which includes a box body 100, cushion blocks 110, a limiting disc 120, a limiting rod 200 and a locking screw. A storage cavity for storing bearings is formed inside the box body 100; a plurality of cushion blocks 110 protrude upward from the bottom surface of the storage cavity, and both the inner and outer rings of the bearing are placed above the plurality of cushion blocks 110; the limiting disc 120 protrudes upward from the bottom surface of the storage cavity, a first nut is arranged above the center of the limiting disc 120, and the plurality of cushion blocks 110 are evenly distributed around the limiting disc 120; the length of the limiting rod 200 is greater than the outer diameter of the outer ring of the stored bearing, and a second nut 210 is arranged at the middle position of the outer surface, and the limiting rod 200 is placed above the bearing; the locking screw 300 includes a screw head 310, an annular handle 320 outside the screw head 310, a head-end thread 301 and a tail-end thread 302 formed on the locking screw 300. The thread directions of the head-end thread 301 and the tail-end thread 302 are opposite. The locking screw 300 passes through the second nut 210, its tail-end thread 302 is operably associated with the first nut, and its head-end thread 301 is operably associated with the second nut 210. The locking screw 300 is rotationally fixed relative to the limiting disc 120 and the limiting rod 200; and among them, an "I" - shaped force - bearing framework is formed among the plurality of cushion blocks 110, the limiting rod 200 and the locking screw 300.
[0027] It should be noted that the diameter of the screw head 310 is greater than the diameter of the second nut 210, which limits the screw head 310 and makes it more convenient for the operator to use when tightening the locking screw 300.
[0028] When the above - mentioned bearing transportation tooling is specifically used, a lifting handle is further provided on the box body 100. When the lifting vehicle is in transit, the hook of the lifting vehicle only needs to be moved into the lifting handle on the box body 100 to achieve flexible handling.
[0029] As Figure 1 and Figure 5 As shown in the figure, preferably, in an embodiment, a support seat 400 is further included. The support seat 400 is placed in the storage cavity, and both the inner and outer rings of the bearing are placed above the support seat 400. The support seat 400 is of a "冂" - shaped structure, and the support seat 400 includes a cross - frame bar 410, a pair of vertical frame bars 420 and a third nut 430. The third nut 430 is arranged above the cross - frame bar 410.
[0030] In an embodiment, the first nut 121, the second nut 210 and the third nut 430 are arranged on the same axis.
[0031] As Figure 6As shown, in one embodiment, the locking screw 300 further includes a middle thread 303 formed on the locking screw 300, the middle thread 303 having the same thread direction as the tail thread 302, the locking screw 300 passing through the second nut 210 and the third nut 430, the middle thread 303 being operatively associated with the third nut 430, and the locking screw 300 being rotatably fixed relative to the limiting plate 120, the limiting rod 200, and the support base 400.
[0032] In one embodiment, the major diameter of the head thread 301 is greater than the major diameter of the middle thread 303, and the major diameter of the middle thread 303 is greater than the major diameter of the tail thread 302.
[0033] In one embodiment, the major diameter of the head thread 301 is larger than the major diameter of the tail thread 302.
[0034] It should be noted that the major diameter of the thread at the head end 301, the major diameter of the thread at the middle section 303, and the major diameter of the thread at the tail end 302 gradually decrease, so that the locking screw 300 can pass smoothly through the second nut 210 and the third nut 430.
[0035] In one embodiment, the height of the limiting disc 120 is less than the height of the pad 110.
[0036] In one embodiment, the pad 110 and the box 100 are made of wood.
[0037] like Figure 3 As shown, preferably, in one embodiment, there are four pads 110.
[0038] In use, the operator places the bearing in the storage cavity and positions it on four pads 110. At this time, one end of the inner and outer rings of the bearing simultaneously contacts the upper surface of the pads 110. Then, the limiting rod 200 is placed above the bearing, at which point the other end of the inner and outer rings of the bearing simultaneously contacts the limiting rod 200. The locking screw 300 passes through the second nut 210, so that the tail thread 302 on the locking screw 300 is threadedly connected to the first nut 121, and the head thread 301 on the locking screw 300 is threadedly connected to the second nut 210. Since the tail thread 302 is a reverse thread and the head thread 301 is a forward thread, when the locking screw 300 rotates relative to the limiting rod 200 and the limiting plate 120, the limiting rod 200 and the pads 110 lock in opposite directions, thus fixing the bearing in the storage cavity.
[0039] Additionally, when a support base 400 is installed on the ground surface of the storage cavity, the locking screw 300 passes through the second nut 210 and the third nut 430, so that the tail thread 302 on the locking screw 300 is threadedly connected to the first nut 121, the middle thread 303 on the locking screw 300 is threadedly connected to the third nut 430, and the head thread 301 on the locking screw 300 is threadedly connected to the second nut 210. Since the tail thread 302 is a reverse thread, the middle thread 303 is a reverse thread, and the head thread 301 is a forward thread, when the locking screw 300 rotates relative to the limiting rod 200, the limiting plate 120, and the support base 400, the limiting rod 200 and the pad 110 are locked in opposite directions, and the limiting rod 200 and the support base 400 are locked in opposite directions, so that its bearing is fixed in the storage cavity.
