Abstract
The utility model relates to a fixed force pull-off safety device, which comprises a shell and a core inserted into the shell, wherein clamping slots are formed on the side wall of the core; and ball contact structures correspondingly matched with the clamping slots are arranged on the shell. When the fixed force pull-off safety device is used, the core can be pulled out of the shell if a force on the same straight line reaches a set value; and after the core is separated from the shell, the force equal to the set value disappears, so that a safety protection function is realized.
Description
Technical field
The utility model relates to a kind of power of deciding and pulls 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.
The model utility content
The purpose of the utility model provides a kind of power of deciding and pulls safety.
For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of power of deciding pulls safety; 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.
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 model utility 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 the further understanding to the utility model, and constitutes the part of specification, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model.In the accompanying drawings:
Fig. 1 is that the utility model is decided the structural representation that power pulls safety.
Embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
As shown in Figure 1; A kind of power of deciding of the utility model 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 embodiment of the utility model; Be not limited to the utility model; Although the utility model 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 the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
