Detailed description of the invention
The Lazy Susan preventing coming off as shown in Figures 1 to 3, comprising: rotor plate 1, base 2, clamp ring 3 and fastener 4, wherein:
Rotor plate 1, is extended with rotating shaft 11 downwards in the middle part of the bottom surface of this rotor plate 1, and the appearance of this rotating shaft 11 is provided with external screw thread (not shown);
Base 2, the bottom surface of the end face support rotor plate 1 of this base 2 and both be rotatably assorted, base 2 has pass for rotating shaft 11 turn hole 21, turn in the base 2 below hole 21 rotation space 22 being provided with and turning hole 21 with this and be communicated with, rotating shaft 11 turns hole 21 with this and is rotatably assorted and stretches into rotation space 22;
Clamp ring 3, the inner ring of this clamp ring 3 is provided with the internal thread (not shown) with external screw thread threaded engagement, and this clamp ring 3 is located on rotating shaft 11 by the threaded engagement of external screw thread and internal thread;
Fastener 4, between base 2 and clamp ring 3, and is separated by with base 2, and to prevent friction, this fastener 4 is affixed removably with rotating shaft 11, clamp ring 3 respectively.
When assembling or dismounting, clamp ring 3 substantially increases mounting or dismounting efficiency with the thread connecting mode of rotating shaft 11, and by turning the spacing of hole 21 and rotating shaft 11, and the support of base 2 pairs of rotor plates 1 and being rotatably assorted, then rotor plate 1 can be stablized, rotate smoothly, simultaneously, clamp ring 3 can easily screw-threaded coupling in rotating shaft 11, and fix removably with fastener 4, clamp ring 3 and rotating shaft 11 timing synchronization are rotated, can prevent clamp ring 3 from getting loose, and have clamp ring 3 due to rotating shaft 11 being locked, then rotating shaft 11 also can not come off from turning hole 21, effectively prevent coming off of rotor plate 1.Rotation space 22 provides the sufficient space of rotation to fastener 4 and clamp ring 3, prevents friction.Base 2 bottom surface turned below hole 21 of this example is extended with pipe 23 downwards, this pipe 23 enclose the space of covering and be rotation space 22.
As shown in Figure 4, the fastener 4 of this example is in ring shape, and be located on rotating shaft 11, the inner ring of this fastener 4 is radially-inwardly protruding with projection 41, rotating shaft 11 has and blocks for projection 41 draw-in groove 111 be inserted into, the outer ring radial phase of this fastener 4 is extended with resilient fingers 42, and this resilient fingers 42 snatch is in clamp ring 3.Inserted the mode of draw-in groove 111 by projection 41, both conjunction convenient for assembly can dismantle, effectively can ensure again the synchronous axial system of fastener 4 and rotating shaft 11, to make resilient fingers 42 effectively fixing and locking circle 3.For further effectively, fixing and locking circle 3 easily, this example resilient fingers 42 be multiple, be distributed in the outer ring of fastener 4, by multiple resilient fingers 42 with uniform force ground fixing and locking circle 3.Resilient fingers 42 is curved, and the end face of clamp ring 3 is provided with inclined-plane 31, is beneficial to resilient fingers 42 pairs of clamp rings 3 further and produces effective grasping force.
As shown in Figure 3, draw-in groove 111 extends to the bottom surface of rotating shaft 11 by the circumferential lateral surface of rotating shaft 11, then, when fastener 4 is upwards overlapped by the bottom of rotating shaft 11, projection 41 also will snap in along draw-in groove 111, improves assembling and removal efficiency.
As shown in Figure 2, between the end face of fastener 4 and the bottom surface of base 2, be provided with the first thrust bearing 5, fastener 4 through this first thrust bearing 5 back-off in turning hole 21 and being rotatably assorted with base 2.First thrust bearing 5 can adopt needle roller thrust bearing, to promote enough axial bearing capacities and overall thinning rotating disk.By the undertaking effect of the first thrust bearing 5, both can effectively prevent fastener 4 and base 2 from rubbing, can make again fastener 4, clamp ring 3 stably back-off in turning hole 21, the rotation of rotor plate 1 will be more steady, even if there is External Force Acting also still can held stationary, improve the effect preventing rotor plate 1 from coming off further.
For convenience of use, as shown in figures 2-3, rotor plate 1 and base 2 all rounded.For strengthening the intensity of base 2 and making the height of whole rotating disk less, the periphery of base 2 is extended with annular seating 24 downwards, the bottom surface of base 2 is also extended with many reinforcements 25 downwards, one end of reinforcement 25 is connected with pipe 23, the other end of reinforcement 25 is connected with annular seating 24, and each reinforcement 25 radially distributes centered by pipe 23.The second thrust bearing 6 is provided with between the end face of base 2 and the bottom surface of rotor plate 1, base 2 is rotatably assorted with rotor plate 1 through this second thrust bearing 6, as shown in Figure 5, the end face of base 2 has the circular groove 26 for holding the second thrust bearing 6, to make rotor plate 1 can relative to the smooth and easy rotation of base 2.Second thrust bearing 6 can adopt needle roller thrust bearing, to promote enough axial bearing capacities and overall thinning rotating disk.
Above-mentioned embodiment is only preferred embodiment of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
