In addition, in moving parts 11, preferably in the part for being possible to contact with guide member 10, being provided with advance by sliding
The guard block of the higher material formation of the less material of dynamic resistance, wear resistance.
If for example, the guard block of tabular, shaft-like to be set in advance as moving along to the long side direction of part 11, even if
Moving parts 11 is moved, and moving parts 11 is not also contacted directly with guide member 10, but guard block connects with guide member 10
Touch.So, if installing the guard block formed by the less material of resistance to sliding in advance, it can prevent because setting moving parts
11st, guide member 10 and cause bar 4 the increased situation of moving resistance.If in addition, installing in advance by the higher material of wear resistance
Expect the guard block formed, be then difficult to the damage for producing moving parts 11, therefore, it is possible to prevent because of the damage of moving parts 11
So that safeguarding the increased situation of frequency.
In addition, being used as the higher material of the less material of resistance to sliding used in guard block, wear resistance, Neng Goulie
Lift the resin materials such as polyethylene, polyamide.
If in addition, guard block to be arranged to moving parts 11 in a detachable manner, even if guard block is damaged
The main body of moving parts 11 is not also damaged, then by change guard block just can continue to carry out operation, therefore also have can
The advantage of easy and putting maintenance into practice operation in short time.If for example, as screw fix, the method by can simply dismount
Guard block is fixed on moving parts 11, then easily carries out the replacement operation of guard block.
In addition, the method that guard block is fixed on moving parts 11 is not particularly limited.For example, except above-mentioned spiral shell
Outside nail is fixed, it can be also fixed by the various methods such as adhesive.If moving parts 11 can be changed simply
Itself, then guard block is secured entirely on the problems such as mode of moving parts 11 will not produce disengaging in use, therefore preferably.
In addition, guard block, which can not be only arranged at moving parts 11, is also provided at guide member 10.In addition, guard block
It can also be not provided with being only arranged at guide member 10 in moving parts 11.
(proximity switch 20)
In addition, for the movement of bar 4, although operator can observe to confirm the shifting of moving parts 11 by visual observation
Move to confirm the movement of bar 4, but can more preferably automatically detect the amount of movement of bar 4.For example, in cylinder body 3, existing in advance
Near the end of the end opposite side protruded with bar 4 switch 20 is positioned proximate to (near right-hand member in Fig. 1).More specifically,
Under the state (state that i.e. cylinder main body 2 is shunk the most) that bar 4 is accommodated in cylinder body 3 completely, in advance before moving parts 11
End is positioned proximate to switch 20 (reference picture 1) near configured position.So, if bar 4 is accommodated in cylinder body 3 completely, approach
Switch 20 detects moving parts 11, therefore, it is possible to automatically grasp the storage of bar 4.So, easily realize with automatically carrying out
The extension for the system that the action of the plug of pin is associated.
