Description

Technical Field

[0001] This application relates to the technical field of mechanical equipment, and particularly relates to a manual rotating table. Background Art

[0002] A manual rotating table is a tool used to precisely adjust the angle or direction of an object. During production processes such as product assembly and testing, it is often necessary to manually rotate the platform. There are mainly the following two purposes for using the rotating platform:

[0003] One: It enables the operator to access different operating surfaces; two: It can implement different operating steps and synchronously perform them at two or more positions.

[0004] In the prior art, during the use of the rotating table, the limit upright post and the limit slot play a fixing role. When manually rotating the rotating table, the limit upright post and the limit slot cooperate to determine the angle of the rotating table. When it is subjected to rotational loads and impact loads during operation, the limit slot may deform. When the accuracy cannot be guaranteed during subsequent use, the entire rotating disk needs to be replaced, resulting in a relatively high cost.

[0005] For example, in a manually rotatable table that is easy to fix with the application number: CN201721089792.X, a technical solution is disclosed, including a footrest limit table, a limit post connection table, a rotating table, etc. The outside of the rotating table is symmetrically distributed with handles. The middle of the rotating table has a limit disk. The inside of the limit disk is evenly distributed with limit post slots. The top of the limit post connection table has a limit post. The limit post is inserted into the limit post slot. The limit post connection table is connected to the rotating table. The bottom of the limit disk has a bearing seat. The middle of the fixed seat has a support shaft. The support shaft is inserted into the bearing seat. The rotating table is connected to the fixed seat. The positioning plate is inserted into the positioning plate slot. The tooth post is inserted into the tooth post slot. The external teeth cooperate with the tooth slots. The lower part of the limit post connection table is evenly distributed with trapezoidal limit tables on both sides. The top of the footrest limit table is evenly distributed with trapezoidal limit table slots. The trapezoidal limit table is inserted into the trapezoidal limit table slot. The lower part of the limit post connection table has an arc-shaped insertion table. The top of the footrest limit table has an arc-shaped insertion table slot. The arc-shaped insertion table is inserted into the arc-shaped insertion table slot; combined with the above description and the attached Figure 2 It can be clearly seen that the limit post slots 32 are evenly distributed inside the limit disk 31, and there are still the above-mentioned problems, that is, when the limit post slots 32 have problems, the entire limit disk 31 needs to be replaced, resulting in a relatively high cost. Moreover, during actual use, the limit post slots 32 cannot be finely adjusted anymore.

[0006] In summary, a new technical solution is needed to solve the above technical problems. Summary of the Utility Model
