Description

Blocking structure

The invention relates to a plug structure, in particular to a plug structure which is provided with a support portion which can prevent the first clamping stop from being cracked when being rotated, and the plug has structural strength. The plug is screwed onto the nut, and the nut is coupled to the main shaft, and the nut is a nut for a precision nut, a lock nut or a rolling bearing.

As previously known, the sealing structure provided on the high-speed spindle and its nut is used, such as Taiwan Patent Application No. 094202119, certificate number M273418, which is the patent application filed by the applicant. The closure structure includes: The utility model relates to a sealing structure of a high-speed spindle and a nut thereof, wherein the sealing body is provided with a screw locking portion with respect to the high-speed spindle or the nut thereof, and the end of the screw locking portion forms a clamping stop portion, and the clamping and stopping portion thereof is A structural form in which the thread is tightened and clamped to form a structure in which the opposing structure forms a stop.

Please refer to the eighth and ninth figures. The eighth figure is a perspective view of the conventional plug 30 structure, and the ninth is a side view of the conventional plug 30 structure. The structure of the plug 30 is the M273418 patent case. The structure of the closure 10 is shown in the drawings. The conventional closure 30 includes a third screwing portion 31, a second clamping stop portion 311, a screwing end portion 312, and a second end surface 32. And the second driving unit 34.

However, the conventional high-speed spindle and its plug sealing structure and the missing of the conventional plug 30 are:

1. The screwing end portion 312 of the plug 30 is in a tapered form, that is, the second clamping stop. The closer the movable portion 311 is to the second end face 32, the thickness is close to zero. If the user applies the force when the plug 30 is screwed into the balance hole 31, the screw end portion 312 is easily broken by the driving force, thus Unable to reach its stop effect.

2. The screwing end portion 312 of the sealing portion 30 is in a tapered shape, that is, the thickness of the second clamping and stopping portion 311 near the second end surface 32 is close to zero, so the screwing is blocked. The action of 30 is basically manual screwing, and in general, there are a plurality of balance holes 31 of the nut 30, and the action of screwing is relatively labor-intensive.

In view of the lack of the above-mentioned conventional plugging structure, the creator has been engaged in the manufacturing development and design experience of related industries for many years, and finally has a product that can solve the drawbacks of the blocked structure.

The conventional sealing device is not structurally strong at the second clamping stop. The sealing structure of the present invention is provided with a supporting portion having a predetermined thickness, and the supporting portion prevents the first clamping. The moving part is cracked when it is rotated, and the sealing has structural strength.

A sealing structure, comprising: a nut, the nut is provided with a fourth screwing portion, and the fourth screwing portion is screwed with a threaded knot structure of a high speed spindle, the nut capping The first screw hole has a first screwing portion; the first screwing hole is internally provided with a first screwing portion; and the plurality of plugging portions are externally provided with a second screwing portion of an external thread shape, the second screwing portion The part is screwed to the first screwing portion of the nut, so that the plugging system is screwed to the first screwing hole of the nut, and the second screwing portion is opposite to the open end of the first screwing hole Forming a first clamping stop portion in a tapered shape, the closure end is provided with a first end surface near one end of the first clamping stop portion, the first clamping stop portion and the first end surface The support system has a support portion having a thickness. That is, the first clamping stop has a thickness at least closest to the first end surface, and the supporting portion has a structural strength at the first clamping stop, and the first end surface is provided with First drive unit.

The sealing portion is provided with a supporting portion, wherein the supporting portion has a structural strength at the first clamping and stopping portion, and the thickness of the first clamping and stopping portion closest to the first end surface is at least a supporting portion When the plug is screwed to the first screw hole, the screwing force of the screw does not cause the first clamp stop to crack. The nut has a plurality of first screw holes. After the plug is provided with a support portion, the plug can be screwed using a pneumatic tool, and the rotary power system of the pneumatic tool is less controllable, but the rotary power is Nor does it damage the first clamping stop, so that the action of screwing the sealing is faster. The plug can achieve fast screw locks and the purpose of using wind noise reduction.
