Abstract
The utility model discloses a piston rod with limit structure, include a piston cylinder and install the piston rod at the piston cylinder inner chamber, the upper end of the inner chamber of piston cylinder is provided with the screw thread, and installs limit structure through the screw thread, limit structure's the threaded board of upper end integrated into one piece, and limit structure lower extreme integrated into one piece has a limiting plate, the intermediate formation mounting groove of screw thread board and limiting plate, the upper end integrated into one piece of piston cylinder has the installation protruding, install adjusting device in the installation arch, rotating -structure is installed to adjusting device's upper end, the structure of device through improving current piston rod not only can the convenient reliable stroke to the piston rod be carried on spacingly, and all devices are seal structure moreover, greatly reduced the possibility of rustting and becoming invalid to axial motion can not take place and can cooperate step motor to reach fine regulation and control effect for adjusting device in accommodation process.
Description
Technical field
This utility model relates to piston rod technical field, a kind of piston rod with position limiting structure.
Background technology
Piston rod is a kind of conventional machinery, is generally used to the executive component as hydraulic means, but along with control
The complexity of system is more and more higher, and equipment sometimes needs the stroke of piston rod to be variable and controlled during using,
Therefore occur in that many piston rod control systems using travel switch to control, but this control system needs to install a lot of control
Electronic structure and need to install a travel switch on the hydraulic stem collapsing length that each is required, this is the most uncomfortable
Unify a little small-scale structure, and part uses the piston rod of external screw thread regulation and control can consume substantial amounts of lubricating oil for antirust, if
Can designing one, that a small amount of structure can be used just precisely effectively to carry out piston rod stroke is spacing and can be the most antirust
Novel piston rod just can solve problems, for this, we carry a kind of piston rod with position limiting structure much of that.
Utility model content
The purpose of this utility model is to provide a kind of piston rod with position limiting structure, to solve in above-mentioned background technology
The problem proposed.
For achieving the above object, this utility model following technical scheme of offer: a kind of piston rod with position limiting structure, bag
Including a piston cylinder and be arranged on the piston rod of piston cylinder inner chamber, the upper end of the inner chamber of described piston cylinder is provided with screw thread, and logical
Crossing screw thread and be provided with position limiting structure, the upper end of described position limiting structure is integrally formed with thread plate, and position limiting structure lower end one becomes
The intermediate formation mounting groove of type limited location plate, described thread plate and limiting plate, and on thread plate, have through hole, described piston cylinder
Upper end, integrally formed with installing projection, described installation projection is provided with adjusting means, and the upper end of described adjusting means is provided with
Rotational structure, and the lower end of adjusting means is provided with the poke rod matched with the through hole on position limiting structure, described poke rod
Bottom is provided with the anti-drop block matched with mounting groove.
Preferably, described rotational structure is the gear teeth or anti-slip veins.
Preferably, described anti-drop block be circular and with poke rod welded and installed.
Compared with prior art, the beneficial effects of the utility model are: this utility model is by improving existing piston rod
Structure, can not only convenient carry out spacing to the stroke of piston rod reliably, and all devices are sealing structure, significantly drop
The low probability lost efficacy of getting rusty, and adjusting means will not occur axially-movable can coordinate motor during regulation
Reach good regulating effect.

Fig. 3 is the structural representation of this utility model position limiting structure.
In figure: 1 piston rod, 2 adjusting meanss, 201 rotational structures, 202 poke rods, 203 anti-drop blocks, 3 installation projections, 4 limits
Bit architecture, 401 through holes, 402 thread plates, 403 mounting grooves, 404 limiting plates, 5 piston cylinders.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1-3, this utility model provides a kind of technical scheme: a kind of piston rod with position limiting structure, including
One piston cylinder 5 and be arranged on the piston rod 1 of piston cylinder 5 inner chamber, the upper end of the inner chamber of piston cylinder 5 is provided with screw thread, and passes through
Screw thread is provided with position limiting structure 4, and the upper end of position limiting structure 4 is integrally formed with thread plate 402, and position limiting structure 4 lower end one becomes
Type limited location plate 404, thread plate 402 and the intermediate formation mounting groove 403 of limiting plate 404, and have through hole on thread plate 402
401, the upper end of piston cylinder 5, integrally formed with installing protruding 3, is installed and is provided with adjusting means 2 on protruding 3, adjusting means 2 upper
End is provided with rotational structure 201, and rotational structure 201 is the gear teeth or anti-slip veins, and the lower end of adjusting means 2 is provided with and spacing knot
The poke rod 202 that through hole 401 on structure 4 matches, the bottom of poke rod 202 is provided with the anticreep matched with mounting groove 403
Block 203, anti-drop block 203 be circular and with poke rod 202 welded and installed, have only to device for regulating rotary 2 scalable during use
The position of position limiting structure 4 thus realize spacing purpose.
Embodiment the most of the present utility model, for the ordinary skill in the art,
It is appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, repair
Changing, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
