Abstract

The utility model relates to an air bag of a positioning safety lock. The air bag of the utility model is an elongated slot-shaped telescopic air bag of which one end is fixed on one end of a cavity, and the other end can move in the cavity. The other end of the air bag is provided with a positioning post which can move in a guide hole of the other end of the cavity. The air bag is driven to telescope by a power source, and the positioning post is forced to move in the guide hole of the other end of the cavity, so a good telescopic ratio is formed. The positioning post can be effectively extended into or drawn back from a positioning hole on a sliding member or a rotating member inside a sliding sleeve or a shaft sleeve, so as to control the movement of a pivot. Accordingly, the purpose that the air bag is not easy to become fatigue and broken is achieved.

Description

The air bag of positioning security lock

Technical field

The utility model relates to a kind of air bag of positioning security lock, the air bag of the positioning security lock that particularly a kind of elongated slot is retractable.

Background technique

The air bag of known positioning security lock 1A is a flat air bag, extremely shown in Figure 7 as Fig. 6, these air bag 70 central tool hole clippings 71, card division 31 for locating column 30 1 ends fastens, the periphery of this air bag 70 is put in the first spiral shell portion 22 of cavity 20, bridges one to be the air packing 41 that encircles frame again, and spiral shell is established the connecting head 50 of a tool reducing screw subsequently, air bag 70 peripheries are anchored on the cavity 20, locating column 30 1 ends can be placed through in the guide hole 24 of cavity 20 the other ends; The second spiral shell portion 23 of mat cavity 20 is screwed in sliding sleeve/axle sleeve 60, so that fixedly spiral shell 231 spiral shells are solid, (figure does not show by power source, as air voltage source) to drive air bag 70 flexible, make locating column 30 stretch into/contract for the positioning hole 62 on slider/rotating component 61 in sliding sleeve/axle sleeve 60, to reach the purpose of control slider/rotating component 61 activities.

Because air bag is subjected to the promotion of power source, to the bigger shearing of periphery generation of air bag, and the distortion that this air bag can produce is limited, and needs very easily cause air bag tired, damaged with bigger power source, and then the flexible function of forfeiture locating column.

Novel content

So the improving of the above-mentioned disappearance of the utility model people thoughts is that the spy concentrates on studies and in conjunction with mechanics principle, propose a kind of reasonable in design and effectively improve the structure of above-mentioned disappearance finally.

Be the working life of the air bag that adapt to promote the positioning security lock, a kind of replacement elastic membrane chip air bag, and only need just can drive locating column and produce the structure that significantly moves with the low-power source, be only basic solution.

Main purpose of the present utility model is to provide a kind of air bag that can significantly carry stretching rate, to promote the working life of air bag, allow low power power source can drive air bag easily, to change the mobile position of locating column effectively, to reach the air bag that is difficult for causing tired, the damaged positioning security lock of air bag.

Its concrete structure is as follows:

The air bag of a kind of positioning security lock is characterized in that this air bag is the end that an end is fixed on cavity, and the retractable air bag of elongated slot that the other end is can be in cavity movable, the other end of this air bag have can be in the guide hole of the cavity the other end movable locating column.

The utility model mainly designs the retractable air bag of the preferable elongated slot of a stretching rate, to replace the flexible sheet of original flexible rate variance, flexible by the drive power source air bag, make locating column movable in the guide hole of the cavity the other end, force locating column to stretch into effectively/contract, with control slider/rotating component activity for the positioning hole on slider/rotating component in sliding sleeve/axle sleeve.

Thereby, reach and be difficult for the purpose that causes air bag tired, damaged; This air bag cooperates the positioning security lock to use, the location that can be applied to various gate switch widely is (as the door body stud shaft positioning control of sterilizing pan/autoclave ... Deng), the automatic straight line is toward covering mobile location (as the refuse arresting gear of lift arm automatic feeder, sluice ... Deng), and the location of automatic rotating shaft rotation angle is (as battery heat shrinking film work station wrapping machine, circular rotary parking lot ... Deng).

For making the auditor can further understand feature and technology contents such as structure of the present utility model, function, effect, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic reference and the explanation usefulness of only providing not is to be used for the utility model is limited.

Embodiment

See also Fig. 1, Fig. 2, disclose a kind of air bag 10 of positioning security lock 1 among the figure, it is the end that an end is fixed in cavity 20, the other end can be in cavity 20 the movable retractable air bag of elongated slot, one end opening tool flange 11 of this air bag 10, be cross-placed on tank 21 outer rims of cavity 20, the other end tool button card division 12, chimeric for the card division 31 of locating column 30; Flange by air packing 40 central tool perforation 41, wear on the flange 11 of air bag 10, with connecting head 50 that the first spiral shell portion, 22 spiral shells of cavity 20 are solid, flange 11 with fixation balloon 10, make the second spiral shell portion 23 of cavity 20 be screwed in sliding sleeve/axle sleeve 60 (as Fig. 5), screw tight with fixing spiral shell 231, (figure does not show by power source, as air voltage source) to drive air bag 10 flexible, it is movable to make in the guide hole 24 of locating column 30 in the second spiral shell portion 23, form easily stretch into/contract (as Fig. 3, shown in Figure 4) positioning hole 62 in sliding sleeve/axle sleeve 60 on slider/rotating component 61, with 61 activities of control slider/rotating component.

The air bag 10 of aforementioned positioning security lock, its longitudinal section is wavy or knuckle shape (figure does not show), and the stretching rate that tool is preferable only needs with the low-power source, just can drive locating column 30 and produce significantly mobile.

See also Fig. 5, the air bag that discloses a kind of positioning security lock among the figure is implemented in the positioning security lock, installs the stereogram on the axle sleeve of rotary work station again.Sliding sleeve/axle sleeve 60 1 ends in work station 6 are provided with slider/rotating component 61, the second spiral shell portion 23 of positioning security lock 1 is fixed on sliding sleeve/axle sleeve 60, so that fixedly spiral shell 231 spiral shells are solid, locating column 30 is penetrated the positioning hole 62 of slider/rotating component 61 by power source, make slider/rotating component 61 location (consulting Fig. 3 simultaneously), process in order to work station; Otherwise, make locating column 30 break away from the positioning hole 62 of slider/rotating component 61 by power source, then rotatable slider/rotating component 61 (consulting Fig. 4 simultaneously) carries out next one processing in order to work station.

The utility model produces significantly mobile by the air bag of drive power source position safety lock, reach and be difficult for the purpose that causes air bag tired, damaged, and can drive locating column easily and stretch into/contract for the positioning hole on slider/rotating component in sliding sleeve/axle sleeve, to reach control slider/rotating component activity, hence one can see that, and the utility model is tool novelty and progressive in fact, the application key element that meets novel patent is filed an application according to Patent Law then.

The above is preferred embodiment of the present utility model only, is not so inflexible limit claim of the present utility model, so the equivalent structure that uses specification of the present utility model and graphic content to do such as changes, all in like manner is contained in the scope of the present utility model.
