Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 shows the structure of such a spinning screw, and several embodiments are listed below with reference to the figures.
Example 1:
a spinning screw comprises a screw 1 and accessories thereof, wherein the accessories comprise a base 2, an intermediate plate 3, a movable plate 4, an upper top plate 5 and a guide post 6 penetrating through the base 2, the intermediate plate 3, the movable plate 4 and the upper top plate 5 from bottom to top, wherein the upper top plate 5, the intermediate plate 3 and the guide post 6 are fixedly connected, and the movable plate 4 and the base 2 are movably connected with the guide post 6; a spring 7 is sleeved on the guide post 6 between the base 2 and the middle plate 3; the screw rod 1 penetrates through the upper top plate 5, the movable plate 4, the middle plate 3 and the base 2, the thread section of the screw rod 1 is arranged between the upper top plate 5 and the middle plate 3, the top end of the screw rod 1 is rotatably connected with the upper top plate 5 through a bearing, the movable plate 4 is rotatably connected with the screw rod 1 through threads, and the middle plate 3 and the base 2 are rotatably connected with the screw rod 1.
The length of the thread section on the screw 1 and the thread pitch are designed according to requirements. When not pressed, the base 2 is supported by the spring 7. When the movable plate 4 is pressed downwards, the screw rod 1 rotates in the movable plate 4 under the action of the threads of the movable plate 4, and meanwhile, the base 2 together with the guide column 6 moves downwards, and the screw rod 1 also moves downwards along with the base, so that the spinning at the bottom end of the screw rod 1 is formed. When in use, the base 2 can be placed at a proper position according to the object to be pressed, and a space for placing the object to be pressed is reserved.
Example 2:
on the basis of the embodiment 1, it is further defined that the bottom end of the threaded section of the screw rod 1 is rotatably connected with the middle plate 3 through a bearing. The rotation of the screw rod 1 is more stable, and the effect is more prominent particularly in a high-speed rotation application scene.
Example 3:
on the basis of embodiment 1, the positions of the guide posts 6 can be designed according to the size of the installation space, the stability requirement and the like, and the guide posts are preferably three or more in number and are uniformly distributed around the circumferential direction of the screw rod 1.
Example 4:
on the basis of the embodiment 1, it is further defined that the upper top plate 5, the middle plate 3 and the guide post 6 are fixedly connected in a manner that a screw 8 is arranged to penetrate through the upper top plate 5 or the middle plate 3 through threads and abut against the side wall of the guide post 6. The fixing of the guide post 6 can be released by taking down the screw 8, and the installation and the disassembly are convenient.
