Abstract
The invention discloses a high-strength screw of a vacuum reaction machine. The high-strength screw comprises a rotating thread, a round sealing pipe is arranged on the side face of the rotating thread, and a square rotating opening is formed in the position opposite to the round sealing pipe. The round sealing pipe is made of elastic abrasion-resistant plastic, and the rotating thread is made of high-strength hard steel. Due to the fact that the round sealing pipe of the high-strength screw of the vacuum reaction machine is made of the elastic abrasion-resistant plastic, the fiction force of the element is increased, and air leakage is avoided. Due to the fact that the rotating thread is made of the high-strength hard steel, the safety of the element can be effectively ensured when the stress is too large.
Description
Technical field
The present invention relates to a kind of screw, or rather, is a kind of vacuum reaction machine high strength screw.
Background technique
Vacuum reaction machine, because by atmospheric pressure effect, is easy to gas leakage at screw interface place.Existing screw lacks high-intensity sealing effect mostly, therefore effectively extends surface of contact and greatly can improve sealing.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provide a kind of can the vacuum reaction machine high strength screw of effective sealing.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of vacuum reaction machine high strength screw, comprise a rotation screw thread, a sealing pipe is established in described rotation screw thread side, and a square rotation mouth is established on described sealing pipe opposite.
As preferred embodiment of the present invention, described sealing pipe is that elastic wear-resisting plastic cement is made.
As preferred embodiment of the present invention, described rotation screw thread is that high strength hard steel is made.
Because the sealing pipe described in vacuum reaction machine high strength screw of the present invention is that elastic wear-resisting plastic cement is made, thus increase the frictional force of this element, avoid gas leakage.Because described rotation screw thread is that high strength hard steel is made, thus when stressed excessive, effectively can ensure the Security of this element.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of vacuum reaction machine high strength screw of the present invention;
Fig. 2 is the perspective view of the vacuum reaction machine high strength screw in Fig. 1, is now another visual angle.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The invention provides a kind of can the vacuum reaction machine high strength screw of effective sealing.
As shown in Figure 1 and Figure 2, a kind of vacuum reaction machine high strength screw 1, comprises a rotation screw thread 2, and a sealing pipe 3 is established in described rotation screw thread 2 side, and a square rotation mouth 4 is established on described sealing pipe 3 opposite.
As shown in Figure 1 and Figure 2, described sealing pipe 3 is made for elastic wear-resisting plastic cement.
As shown in Figure 1 and Figure 2, described rotation screw thread 2 is made for high strength hard steel.
The sealing pipe described in vacuum reaction machine high strength screw of this invention is that elastic wear-resisting plastic cement is made, thus increases the frictional force of this element, avoids gas leakage.Because described rotation screw thread is that high strength hard steel is made, thus when stressed excessive, effectively can ensure the Security of this element.
Below only in one embodiment mentality of designing of the present invention is described, when system allows, the present invention can expand to external more function module simultaneously, thus expands its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
Claims (3)
1. vacuum reaction machine high strength screw (1), comprise a rotation screw thread (2), it is characterized in that, a sealing pipe (3) is established in described rotation screw thread (2) side, and a square rotation mouth (4) is established on described sealing pipe (3) opposite.
2. vacuum reaction machine high strength screw according to claim 1, is characterized in that, described sealing pipe (3) is made for elastic wear-resisting plastic cement.
3. vacuum reaction machine high strength screw according to claim 2, is characterized in that, described rotation screw thread (2) is made for high strength hard steel.
