Description
Technical field
Provided by the utility model is the support rod of machinery field, be mainly used in various military equipments, engineering machinery and
Special vehicle is supported in the chamber door of fixation, moving condition.Specifically mechanical detent positioning support bar.
Background technique
Currently, support rod generallys use gas formula drive mechanism, mainly play a supportive role.Its working principle is that: in sealed tube
It inside fills high pressure gas with, has through-hole on moving piston, guarantee that the pressure in entire iron pipe will not change with the movement of piston.
And if Pneumatic power support lever advocate iron pipe and external atmosphere pressure acts on pressure difference in cross section of the piston rod.Pneumatic power support lever
Using high-pressure inert gas as power, support force is stable in entire impulse stroke.And there is buffer gear, it avoids in place
Impact, this is an advantage over the maximum feature of common support bar.And have the advantages that it is easy for installation, using safe, service free.Due to
Atmospheric pressure in seal pipe is constant, and the cross section of piston rod is certain, thus in entire stroke Pneumatic power support lever power
It keeps stablizing.
Pneumatic power support lever length longest in a free state can be by after by the ambient pressure of itself thrust is greater than
Compression, until minimum length.Pneumatic power support lever is when the external world applies pressure
With tensional state and two kinds of compressive state, can not voluntarily be locked in the stroke of work.
Summary of the invention
In order to make support rod, voluntarily locking positioning, the utility model provide mechanical detent in stretching travel
Positioning support bar.The support rod is stretched in socket and is turned to by the way that pawl is arranged in the interior ratchet holder coupled with six rib bars of socket
The technical issues of six rib rod lockings are positioned, solve support rod locking positioning by position rotary pawl.
The utility model solves scheme used by technical problem:
It is equipped with cylinder end connector in the side of socket, the other end is provided with six rib bars, and the outer end of six rib bars is equipped with rod ends,
The inner end of six rib bars is connected with ratchet holder by attachment pegs and slides in socket, and the lower part of ratchet holder is connected with power assistant spring.
Outer surface one end of the socket is cylinder, and other end ladder is punctured into six prismatics.
It is respectively equipped with stretching in the cylinder of the six prismatic proximal end of socket to turn to position and shrink steering position, and outside socket
The cylinder of end setting, which is put on, is correspondingly provided with head protector.
The ratchet holder is ladder circle cylindricality, and outer end is connect by attachment pegs with six rib bars, and passes through extension spring and pad
Circle is limited in socket ladder and shrinks at six prismatics.
The ratchet holder inner end is equipped with through slot, and pawl and the steering spring fixed using straight pin are equipped in through slot.
Good effect, since the utility model is commutated using pawl in stretching steering position and is locked on it；It is mentioned when contraction
Six rib bars are risen to steering position is shunk, pawl direction is turned and slides into tube walls, shrink support rod, quickly support, firm position, solve
Determined support rod voluntarily locking positioning the problem of.It is suitable for being used as positioning support bar.
Detailed description of the invention
Fig. 1 is the utility model main view.
In figure, 1. sockets, 1.1., which is stretched, turns to position, and 1.2., which is shunk, turns to position, 2. end connectors, 3. 6 rib bars, 4. rod ends
Connector, 5. ratchet holders, 5.5. through slot, 6. attachment pegs, 7. power assistant springs, 8. sets, 9. head protectors, 10. pawls, 11. straight pins,
12. steering spring, 13. extension springs, 14. washers.
Specific embodiment
According to the figure, it is equipped with cylinder end connector 2 in the side of socket 1, the other end is provided with six rib bars 3, the outer end of six rib bars
Equipped with rod ends 4, the inner end of six rib bars is connected with ratchet holder 5 by attachment pegs 6 and slides in socket, and the lower part of ratchet holder connects
It is connected to power assistant spring 7.
Outer surface one end of the socket is cylinder, and other end ladder is punctured into six prismatics.
Stretching is respectively equipped in the cylinder of the six prismatic proximal end of socket to turn to position 1.1 and shrink steering position 1.2, and
Head protector 9 is correspondingly provided on the cylinder set 8 of socket outer end setting.
The ratchet holder is ladder circle cylindricality, and outer end is connect by attachment pegs with six rib bars, and passes through 13 He of extension spring
Washer 14 is limited in socket ladder and shrinks at six prismatics.
The ratchet holder inner end is equipped with through slot 5.5, and pawl 10 and the steering bullet fixed using straight pin 11 are equipped in through slot
Spring 12.
Working principle of the utility model is:
When six rib bar art skatings, pawl is forward slided in tube walls, when reaching stretching steering position, is provided with pawl rotation
Turn space, while steering spring band pawl rotates, the head of pawl, which slides into stretch, turns to position, so that six rib rod lockings position；
When to shrink six rib bars, first stretching six rib bars and pawl is made to enter contraction steering position, pawl is provided with revolution space, is turning to
Under the drive of spring, pawl rotates so that the head of pawl is attached to tube walls and releases locking, in the effect of power assistant spring
Under, six rib bars are contracted to socket.
The course of work of the utility model:
1, six rib bars are pulled when support rod is stretched, pawl is forward slided in tube walls, is reached stretching on socket and is turned
When to position, steering spring pulls pawl rotation simultaneously to turn to position locking positioning stretching, and the positioning of six rib bars is stretched as holding state.
2, six rib bars are pulled when support rod is shunk, the pawl of locking is slided to when shrinking steering position, and extension spring is loose
Pawl is opened, so that pawl rotation slides into tube walls, under the auxiliary of power assistant spring, six rib bars are punctured into free state.
The characteristics of the utility model:
(1) easy to use: door need to only be reached when enabling after design height can voluntarily locking, operator has when door standard-sized sheet
Door at closing time only automatic unlocking and need to can smoothly be closed the slightly upper lift of door by obvious feel.
(2) good reliability: product is that mechanical rigid support construction intensity is high, and six rib bar axially positions are reliable and stable, single
Bearing capacity be greater than 6000N, there is good wind resisting stability, under the conditions of nine grades of strong gales, support car door that still can be stable.
Long service life: element is preferably made of stainless steel, wear-resistant, anticorrosive, and the overall work service life is more than
20000 times.
