Abstract
A kind of fixed turgor cylinder mandrel, relate to oil cylinder production and processing technical field, its main body is mandrel rod, it is characterized in that: the port of described mandrel rod is provided with notch, and the port of mandrel rod is arranged with tensioning ring, and the bottom of tensioning ring is provided with back-up ring.The beneficial effects of the utility model: the utility model utilizes nylon rod to have the feature of very obdurability, tightens up the port of oil cylinder mandrel, effectively control mandrel port spreading degree in the running, and can carry out in time tightening up recovery after spreading.Port has four notches, and what be conducive to port tightens up recovery.
Description
Technical field:
The utility model relates to oil cylinder production and processing technical field, particularly relates to a kind of fixed turgor cylinder mandrel.
Background technology:
Oil cylinder mandrel used in the market all adopts rubber ring as tensioning ring, and rubber ring is easily aging, and the elasticity of rubber ring is large, but the dynamics of tightening up of rubber ring is less, to the port of oil cylinder mandrel play to tighten up active force little.And rubber ring is once after aging, need to change tensioning ring, need to change after oil cylinder dismounting.Because rubber ring is soon aging, easily damaged, need frequently to change, add work difficulty and labour intensity.And the port of oil cylinder mandrel on market is three notches, when after oil cylinder mandrel spreading, under the tightening up of rubber ring, be difficult to recover.
Utility model content:
Technical problem to be solved in the utility model is the defect overcoming prior art, provides a kind of and has very strong tightening force and the fixed turgor cylinder mandrel easily recovered.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of fixed turgor cylinder mandrel, its main body is mandrel rod, it is characterized in that: the port of described mandrel rod is provided with notch, and the port of mandrel rod is arranged with tensioning ring, and the bottom of tensioning ring is provided with back-up ring.
Described tensioning ring is that nylon rod is made.
Described tensioning ring is located at outside notch.
The port of described mandrel rod is provided with four notches, and mandrel rod port is divided into four parts by four notches.
The beneficial effects of the utility model: the utility model utilizes nylon rod to have the feature of very obdurability, tightens up the port of oil cylinder mandrel, effectively control mandrel port spreading degree in the running, and can carry out in time tightening up recovery after spreading.Port has four notches, and what be conducive to port tightens up recovery.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of fixed turgor cylinder mandrel, its main body is mandrel rod 1, and the port of its mandrel rod 1 is provided with notch 4, and the port of mandrel rod 1 is arranged with tensioning ring 2, and the bottom of tensioning ring 2 is provided with back-up ring 3.Tensioning ring 2 is made for nylon rod.Tensioning ring 2 is located at outside notch 4.The port of mandrel rod 1 is provided with four notches, 4, four notches 4 and mandrel rod 1 port is divided into four parts.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
