Accuracy of measurement and measurement efficiency.
In order to solve the above technical problems, the technical solution that the utility model uses is：A kind of table of adjustable height is provided
Frame cushion cover, including：Cushion cover body contains external screw thread with set, the top of the cushion cover body is heightened, and lower part is smooth cylindrical surface, described
Contain ratchet between external screw thread and cylindrical surface, internal thread is contained on the top for heightening set, and lower part is along the circumferential direction symmetrical and equal
Even that two pieces of pawls are distributed with, the internal thread is engaged with the external screw thread, and two pieces of pawls are engaged with the ratchet.
In one preferred embodiment of the utility model, the dial framework cushion cover of the adjustable height, which further includes, to be rotatably installed in
Cushion cover body and the auxiliary sleeve between set is heightened, the auxiliary sleeve is in circular ring structure, and top is along the circumferential direction symmetrical and is uniformly distributed
There are two casting lug thereons；Two casting lug thereons are installed on respectively between two pieces of pawls, and the upper surface of the auxiliary sleeve with
The lower face for heightening set is in contact.
In one preferred embodiment of the utility model, the number of teeth of the ratchet is 20, screw pitch 1mm.
In one preferred embodiment of the utility model, the auxiliary sleeve can be rotated by 90 ° -180 ° counterclockwise along ratchet.
The beneficial effects of the utility model are：
（1）Padded precision is substantially increased, 0.05mm can be accurate to, can effectively ensure that the measurement accuracy of measurement dial framework；
（2）Padded regulating time is highly shortened, so as to improve the efficiency of bearing measuring；
（3）Versatility enhances, and greatly reduces stock's storage level.

Specific embodiment
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
- Fig. 5 is please referred to Fig.1, the utility model embodiment includes：
A kind of dial framework cushion cover of adjustable height, it is shown as shown in Figure 1, Figure 3 and Figure 4, including：Cushion cover body 1 and heighten set 2, the pad
External screw thread 11 is contained on the top of body 1, and lower part is smooth cylindrical surface 13, contains spine between the external screw thread 11 and cylindrical surface 13
Internal thread 21 is contained on wheel 12, the top for heightening set 2, and lower part is along the circumferential direction symmetrical and is evenly distributed with two pieces of pawls 22,
The internal thread 22 is engaged with the external screw thread 11, and two pieces of pawls 22 are engaged with the ratchet 12.When needing table
When the height of frame cushion cover is heightened, it can directly rotate and heighten set 2 to increase the height of dial framework cushion cover.
