Abstract
The utility model relates to a rotary clamping cylinder which is effective in sealing. The rotary clamping cylinder comprises a body, a front cover and a piston rod which is arranged inside the body. The front cover is provided with a center hole, and the piston rod penetrates out from the center hole of the front cover. The side wall of the body is provided with a screw hole, and a screw is arranged inside the screw hole. A screw rod is provided with a circular groove, and a sealing ring is arranged inside the circular groove. The outer wall of the front cover is provided with a positioning groove, and the end portion of the inner side of the screw is clamped inside the positioning groove. The rotary clamping cylinder has the advantages that standstill locking of the front cover is guaranteed and a good sealing effect is achieved, and is suitable for popularization and application.
Description
Technical field
The utility model relates to a kind of cylinder, relates in particular to a kind of revolution clamping cylinder.
Background technique
Revolution clamping cylinder as shown in Figure 1, comprise body 1, protecgulum 2, piston rod 3, screw 4, wherein in the locating slot of screw 4 precession protecgulums 2, start-stop transfers to use, and cementing seals on the screw thread of screw 4, its shortcoming is: as fruit product screw place after assembling is completed phenomenon that leaks air, because screw sticks together with body 1, refitting might destroy the situation of body 1 screw thread, therefore is difficult for reprocessing.
In Fig. 2, be to add a seal ring 5 in the middle of two screws 4, its shortcoming is: it has used three component to reach spline and seal action, has increased cost from operation; Be difficult for being mounted to ideal position when the assembling seal ring, cracky causes gas leakage; The screw of lower end is in operation easy to break.
The model utility content
The purpose of this utility model is to provide the revolution clamping cylinder of a kind of spline screw place effective sealing, to solve the problem that exists in background technique.
To achieve these goals, the technological scheme of the utility model revolution clamping cylinder is: a kind of revolution clamping cylinder, comprise body, protecgulum and be located at intrinsic piston rod, be covered with center hole before described, described piston rod passes from the center hole of protecgulum, described body sidewall is provided with screw, be provided with screw in screw, described lead screw is provided with circular groove, is provided with seal ring in circular groove, described front cover outer wall is provided with locating slot, and described screw inner end snaps in described locating slot.The design philosophy of this technological scheme is: section offers circular groove in lead screw, and the circular groove built-in ring had both guaranteed the protecgulum spline, had played again good sealing effect.
As preferably, described locating slot is circular blind hole, and its aperture and described screw inner end are adaptive.This is intended to guarantee that protecgulum can not shake.
As preferably, the inner end of described screw is polished rod, and described locating slot is unthreaded hole.
As preferably, described circular groove is positioned at the outboard end of lead screw.If circular groove is positioned at lead screw middle part or darker position, to be selected into the degree of depth excessive for seal ring, be difficult for being mounted to ideal position, and seal ring weares and teares easily.
As preferably, described screw is the hexagon socket head double-screw bolt.According to actual needs, the hexagon socket head double-screw bolt can screw in screw on body, can not expose impact operation and attractive in appearance.
The beneficial effect of the utility model revolution clamping cylinder is: both guaranteed the protecgulum spline, played again good sealing effect.
Description of drawings
Fig. 1 is a kind of structural representation of revolution clamping cylinder in prior art;
Fig. 2 is the another kind of structural representation of revolution clamping cylinder in prior art;
Fig. 3 is a kind of structural representation of the utility model revolution clamping cylinder.
Number in the figure is respectively: 1. body 2. protecgulum 3. piston rod 4. hexagon socket head double-screw bolt 5. seal rings.
Embodiment
Also by reference to the accompanying drawings the technical solution of the utility model is further described specifically below by embodiment.
Embodiment:
a kind of revolution clamping cylinder, as shown in Figure 3, comprise body 1, protecgulum 2 and be located at piston rod 3 in body 1, described protecgulum 2 is provided with center hole, described piston rod 3 passes from the center hole of protecgulum 2, described body 1 sidewall is provided with screw, be provided with hexagon socket head double-screw bolt 4 in screw, the inner end of hexagon socket head double-screw bolt 4 is polished rod, the outboard end of hexagon socket head double-screw bolt 4 has circular groove, be provided with seal ring 5 in circular groove, described protecgulum 2 outer walls are provided with locating slot, this locating slot is circular blind hole, and be unthreaded hole, its aperture and hexagon socket head double-screw bolt 4 inner ends are adaptive, described hexagon socket head double-screw bolt 4 inner ends snap in described locating slot.
During use, both guarantee the protecgulum spline, played again good sealing effect.
Above-mentioned described specific embodiment is only that the preferable examples explanation is done in design of the present utility model.All any modifications of making within spirit of the present utility model and principle or replenish or be equal to alternative, within all should being included in the protection domain of the utility model claim.
