In order to achieve the above purpose, the technical scheme of the utility model is that: a semi-paste sealing device comprises a vacuum chamber base, a vacuum chamber cover, a vacuum chamber rotating arm, a vacuum chamber rotating shaft and a semi-paste sealing mechanism, wherein the vacuum chamber cover is installed at the top of the vacuum chamber base through the vacuum chamber rotating arm, a vacuum chamber is arranged on the front end face of the vacuum chamber base, the vacuum chamber is installed on the vacuum chamber base through the two vacuum chamber rotating shafts, and the bottom of the vacuum chamber rotating shaft is installed on the vacuum chamber base through the semi-paste sealing mechanism.

Preferably, the semi-paste sealing mechanism comprises a high-elasticity plastic body, a semi-paste cavity, deep groove ball bearings, a supporting copper sleeve and a fastening nut, wherein a high-elasticity plastic body installation cavity is formed in the joint of the outer wall of the vacuum chamber rotating shaft and the vacuum chamber base downwards, a high-elasticity plastic body is installed in the high-elasticity plastic body installation cavity, the semi-paste cavity is installed at the bottom of the high-elasticity plastic body, the upper deep groove ball bearings and the lower deep groove ball bearings are installed at the periphery of the outer wall of the vacuum chamber rotating shaft at certain intervals, the supporting copper sleeve is installed between the two deep groove ball bearings, and the fastening nut is installed below the deep groove ball bearings at the lower position and on the end face of the bottom of the vacuum chamber base.

Preferably, the semi-paste cavity is filled with a semi-paste lubricant.

Preferably, two groups of O-shaped rings are sequentially arranged on the side wall of the supporting copper sleeve from inside to outside.

Preferably, the high-elasticity plastic body is in interference fit with the high-elasticity plastic body installation cavity and the vacuum chamber rotating shaft respectively.

Due to the adoption of the technical scheme, the beneficial effects of the utility model are that: the utility model discloses a half cream form emollient is in time sealed to the gap that produces at the rotation in-process between real empty room pivot and the real empty room, can not produce gas leakage phenomenon, because half cream form emollient is the fluid, consequently can realize the dynamic seal, and sealed effect is better, and the consumption is few moreover, need not often change, can effectively practice thrift the manufacturing cost who produces because of changing O type circle.

Drawings

The present invention will now be further described with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is the schematic diagram of the semi-section structure of the utility model.

In the figure: 1. the vacuum chamber comprises a vacuum chamber base, 2, a vacuum chamber cover, 3, a vacuum chamber rotating arm, 4, a vacuum chamber rotating shaft, 5, a semi-paste sealing mechanism, 51, a high-elasticity plastic body, 52, a semi-paste cavity, 53, a deep groove ball bearing, 54, a supporting copper sleeve, 55, a fastening nut, 56, a high-elasticity plastic body mounting cavity, 57, a semi-paste lubricant, 58, an O-shaped ring, 6 and a vacuum chamber.

Detailed Description

As shown in fig. 1 and 2, the utility model relates to a half cream sealing device, including real empty room base 1, vacuum chamber cap 2, real empty room rocking arm 3, real empty room pivot 4 and half cream sealing mechanism 5, real empty room base 1 top is installed vacuum chamber cap 2 through real empty room rocking arm 3, and the terminal surface is equipped with real empty room 6 before real empty room base 1, real empty room 6 is installed on real empty room base 1 through two real empty room pivots 4, the bottom of real empty room pivot 4 is installed on real empty room base 1 through half cream sealing mechanism 5.
