Abstract
The invention relates to a pull-apart safety at a constant force, which comprises a casing and a core inserted in the casing, wherein a clamping groove is arranged in the side wall of the core; and a roller latch structure which is correspondingly matched with the clamping groove is also arranged on the casing. When the pull-apart safety at the constant force which is disclosed by the invention is in use and a force on the same straight line reaches a set value, the core can be extracted from the casing; and after the core is separated from the casing, the force reaching the set value disappears and further the function of safely protecting is achieved.
Description
Technical field
The present invention relates to a kind of power of deciding and pull safety, particularly a kind of safety protection device that can be split up into two bodies when on straight line, receiving a certain size power automatically.
Background technique
In the use of reality, in the time of need working as the power that on same straight line, receives sometimes and reach certain value, connect two and can separate automatically by the object of this power, make the disappearance that this power is unexpected, to play the effect of safety protection.But, also have no a product can satisfy this requirement in the existing technology.
Summary of the invention
The purpose of this invention is to provide a kind of power of deciding and pull safety.
Be to realize above-mentioned purpose, the invention provides following technological scheme: a kind of decide power pulls safety, comprises the fuse that housing is interior with being plugged in housing, and the sidewall of fuse is provided with draw-in groove, also be provided with on the said housing with the draw-in groove corresponding matching bump the pearl structure.
The said pearl structure of bumping comprises the little mounting hole of outer imperial palace that radially is provided with along housing, and the inboard of mounting hole is provided with steel ball, the outside jackscrew that is spirally connected, and between jackscrew and steel ball, is pressed with spring.
Said housing is a cylindrical housings, is provided with blind hole in this housing, and said fuse correspondence is plugged in the blind hole.
Said housing two is connected with first steel wire, and fuse is provided with second steel wire.
The power of deciding of this invention pulls safety and in use is, when the power on same straight line reached setting value, fuse will be extracted in housing, and fuse is with after housing separates, and the power of above-mentioned setting value will disappear, and has played the effect of safety protection.
Description of drawings
Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of specification, is used to explain the present invention with embodiments of the invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is that the present invention decides the structural representation that power pulls safety.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
As shown in Figure 1; A kind of power of deciding of the present invention pulls the embodiment of safety; Comprise a columniform housing 32, housing 32 is provided with a blind hole 36, in this blind hole, is fitted with a columniform fuse 31; The sidewall of fuse 31 is provided with the draw-in groove of annular, on the sidewall of housing, also be provided with two with the draw-in groove corresponding matching bump the pearl structure.This bumps the pearl structure and comprises the little mounting hole of outer imperial palace that radially is provided with along housing; The inboard of mounting hole is provided with steel ball 33, and steel ball 33 matches with draw-in groove, and the arranged outside of mounting hole has jackscrew 34; Between jackscrew and steel ball, be pressed with spring 35; Can control the power that fuse is extracted in the housing through the adjustment jackscrew very easily to the decrement of spring, promptly when needing to transfer the power of extracting greatly, that jackscrew is inwardly stubborn; Increase the decrement of spring, reduce the power that fuse is extracted in the housing otherwise outwards twist the decrement that reduces spring.In addition, on housing, be connected with first steel wire 37, on fuse, be connected with second steel wire 30.
What should explain at last is: the above is merely the preferred embodiments of the present invention; Be not limited to the present invention; Although the present invention has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, and perhaps part technical characteristics wherein is equal to replacement.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (4)
1. decide power and pull safety for one kind, it is characterized in that: comprise housing and the fuse that is plugged in the housing, the sidewall of fuse is provided with draw-in groove, also be provided with on the said housing with the draw-in groove corresponding matching bump the pearl structure.
2. the power of deciding according to claim 1 pulls safety; It is characterized in that: the said pearl structure of bumping comprises the little mounting hole of outer imperial palace that radially is provided with along housing; The inboard of mounting hole is provided with steel ball, the outside jackscrew that is spirally connected, and between jackscrew and steel ball, is pressed with spring.
3. the power of deciding according to claim 1 and 2 pulls safety, it is characterized in that: said housing is a cylindrical housings, is provided with blind hole in this housing, and said fuse correspondence is plugged in the blind hole.
4. the power of deciding according to claim 3 pulls safety, it is characterized in that: said housing two is connected with first steel wire, and fuse is provided with second steel wire.
