End cap and pressure cylinder seal end cap, are equipped with telescopic elastic telescopic between piston rod packing end cap and pressure cylinder sealing end cap
Connector sleeve, piston rod packing end cap and pressure cylinder sealing end cap are located at the both ends of intermediate expansion section pipe.The utility model knot
Structure is simple, at low cost, can effectively prevent dust adherency on the piston rod；But the device dirt-proof boot both ends are using simple set
It connects, only carries out the device that short distance moves repeatedly suitable for similar piston rod, operating path variation this for feed screw nut is greatly
Device be easier to fall off, and the rear enclosure that falls off picks up to be more troublesome.
Summary of the invention
In order to solve the above-mentioned technical problem, the utility model aim is to propose that a kind of fast-connecting type for feed screw nut is flexible
Dirt-proof boot, can effective dust while, easy to connect, fixation, economic cost is low.
In order to achieve the above technical purposes, the utility model uses following technical scheme:
A kind of fast-connecting type flexible dustproof set for feed screw nut, including telescopic dirt-proof boot ontology, the dirt-proof boot
Ontology is the cylinder of several annular corrugated pipes composition；The dirt-proof boot further includes the fixation machine for being fixedly arranged on dirt-proof boot body end
Structure；The fixed mechanism includes the interior fixed part that outer fixing portion and outer wall are fixedly connected with outer fixing portion inner wall；Outer fixing portion
Outer wall is equipped at least one shackle member for being used for connection wire rod pair of nut；The sidewall thickness of interior fixed part is along close to dirt-proof boot sheet
The direction of body gradually increases.
Preferably, the outer wall of the outer fixing portion offers annular groove, and dirt-proof boot ontology and outer fixing portion pass through setting
It is detachably connected in the clip in annular groove；By the way that dirt-proof boot ontology to be detachably connected with outer fixing portion, when dirt-proof boot sheet
When body is damaged because using, can replacement dirt-proof boot ontology, effectively save economic cost.
Preferably, the shackle member includes pedestal and claw；Flexible connector is equipped between the claw and pedestal, thus
It not only can quickly but also firmly realize the connection of dirt-proof boot and feed screw nut.
It is further preferred that the flexible connector is spring.
Preferably, the shackle member includes pedestal, claw and press strip；The pedestal is hinged with press strip end, the card
It is hinged in the middle part of pawl end and press strip, rotate clawed end portions can along press strip end；By pressing down on press strip tail end, make claw
It is mobile to nearly dirt-proof boot end；It is lifted up press strip tail end, it is mobile to remote dirt-proof boot end to make claw, to realize easily and fast anti-
The fixation and disassembly of dirt set.
Preferably, the material of the outer fixing portion is metal or PCV, and the material of the interior fixed part is rubber or excellent power
Glue, thus guarantee that fixed part both has certain degree of hardness, it is wear-resisting firm, and it is convenient for grafting, it is connected firmly.
Dirt-proof boot described in the utility model when in use, the fixed part at dirt-proof boot ontology both ends respectively with feed screw nut pair or
The quick grafting of dirt-proof boot and feed screw nut pair or rack is realized in rack connection by inner wall in the interior fixed part of gradient setting,
Then by the shackle member and feed screw nut pair or rack clamping on the outside of outer fixing portion, dirt-proof boot is further fixed；When dirt-proof boot sheet
When body appearance abrasion needs replacing, the clip that will be connected and fixed dirt-proof boot ontology and fixed part unclamps, and replacement dirt-proof boot ontology is
Can, simple and convenient, economic cost is low.
Detailed description of the invention
The structural schematic diagram of Fig. 1 the utility model fast-connecting type flexible dustproof set；
Fig. 2 is the schematic diagram of dirt-proof boot ontology in Fig. 1.
Specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.Embodiment be merely to illustrate and
Unrestricted the technical solution of the utility model, any modifications or substitutions for not departing from the spirit and scope of the utility model, should all
Cover within the scope of the utility model claims protection.
Embodiment
A kind of fast-connecting type flexible dustproof set for feed screw nut, as depicted in figs. 1 and 2, including by several annular ripples
The telescopic cylinder-shaped dirt-proof boot ontology 1 of pipe composition and the fixed mechanism set on 1 end of dirt-proof boot ontology；The fixed mechanism
Interior fixed part 3 including metal material columnar outer fixing portion 2 and rubber material, the outer wall and outer fixing portion 2 of interior fixed part 3
Inner wall bonding；The sidewall thickness of interior fixed part 3 is gradually increased along the direction close to dirt-proof boot ontology 1, is set by inner wall in the gradient
The interior fixed part 3 set is convenient for the quick grafting of dirt-proof boot and feed screw nut pair or rack；
The outer wall of outer fixing portion 2 offers annular groove, and dirt-proof boot ontology 1 is recessed by being set to annular with outer fixing portion 2
