Abstract
The utility model discloses a combined fastening structure, comprising a piston rod and further comprising a bushing, a sleeve and a clamp spring, wherein the bushing is in a detachable structure; the detachable bushing is clamped in a concave ring at the end part of a piston; and the sleeve is sleeved on the bushing and is positioned through the clamp spring. A spiral friction force on the end part of the former piston is converted into a squeezing force, so that the fastening is firm; the service life of the piston rod is prolonged; and the combined fastening structure is convenient to mount and dismount and is convenient to maintain.
Description
Technical field
The utility model relates to the mechanical fasteners technical field, especially relates to a kind of compound fastening structure.
Background technique
At present, the multiplex serrated nut fastening structure of the head of piston rod, serrated nut fastening structure using scope is wider.But this kind fastening structure has the following disadvantages:
1, the serrated nut Structural Joint is long-pending less, when thrust is larger, is prone to the slide nut dental phenomenon, affects fastening effect;
2, the slide nut dental phenomenon occurs, be not easy to maintenance.
The model utility content
Technical problem to be solved in the utility model provides a kind of compound fastening structure, to reach fastening firm, long service life, purpose easy to maintenance.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of compound fastening structure, comprise piston rod, also comprise edge cover, sleeve, jump ring, described edge cover is detachable structure, detachable edge cover is stuck in the scrobicular ring on the piston rod end, and jacket casing puts and locates by jump ring at edge.
Described edge cover is two symmetrical opening structures.
Described edge puts the jump ring groove that is provided with adaptive jump ring.
The utility model compared with prior art has the following advantages: the spiral friction power that original piston rod end is born has changed into extruding force, and is fastening firm, and piston rod prolongs working life, and easy accessibility is convenient to maintenance.
Description of drawings
The below makes brief description to the expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure:
Fig. 1 is the compound fastening structure schematic representation of the utility model.
Fig. 2 is the utility model structure of mosaic schematic representation.
Among the figure: 1. piston rod, 2. edge cover, 3. sleeve, 4. jump ring.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of compound fastening structure, comprise piston rod 1, edge cover 2, sleeve 3, jump ring 4, end at piston rod 1 is provided with scrobicular ring, edge cover 2 is detachable structure, in detachable edge cover 2 scrobicular rings that are stuck on piston rod 1 end, sleeve 3 is enclosed within on the edge cover 2 and passes through jump ring 4 location.The spiral friction power that original piston rod end is born has changed into extruding force, and is fastening firm, prolongs the working life of piston rod.
Preferably, edge cover 2 is two symmetrical opening structures.Easy accessibility is convenient to maintenance.
Preferably, edge cover 2 is provided with the jump ring groove of adaptive jump ring 4.Prevent the sleeve loose or dislocation, the location is reliable, guarantees fastening reliability.
Simple in structure, the easy accessibility, fastening firm of compound fastening structure of the present utility model.Only need during dismounting jump ring is taken off, withdraw from sleeve, can take off the edge cover.The lifting surface area of piston rod end can change according to the scrobicular ring diameter of piston rod end, and the spiral friction power that the nut of original piston rod end is born is transformed into the extruding force of piston rod, and piston rod prolongs working life relatively.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technological scheme carry out; or without improving design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
