Abstract
The utility model discloses a kind of one-way cylinder without oil pocket buffer structure, it includes piston（1）, it is characterised in that piston（1）It is interior to be equipped with plunger（3）, piston（1）And plunger（3）Between form cushion chamber（10）, plunger（3）In be equipped with nylon block（2）, piston（1）It is threadedly coupled piston rod（4）, piston（1）It is equipped with and cushion chamber（10）The hole communicated.The utility model is simple in structure, applied widely, and occupied space is few, good buffer effect, and buffering effect can be quantified and controlled, and solve the problems, such as that one-way cylinder can not realize hydraulic cushion without oil pocket.
Description
Technical field：
A kind of buffer structure, more particularly to a kind of one-way cylinder be the utility model is related to without oil pocket buffer structure.
Background technology：
Conventional cylinder buffer structure is required for cylinder buffer end to have hydraulic oil, by piston rod or piston extrusion protecgulum or
Hydraulic oil in rear cover cushion chamber comes into row buffering, and the chamber for not having hydraulic oil in one-way cylinder does not realize hydraulic way
Buffering.Even if one-way cylinder oil-free side can realize that buffering is also the mechanical damping of increase spring etc, buffering effect is undesirable
And service life is shorter.
Utility model content：
A kind of simple in structure, scope of application is provided the purpose of the utility model is to overcome the deficiency of above-mentioned prior art
Extensively, occupied space is few, good buffer effect, and buffering effect can be quantified and controlled, the one-way cylinder oil-free of service life length
Chamber buffer structure.
The purpose of this utility model can be reached by following measure：A kind of one-way cylinder without oil pocket buffer structure,
It includes piston, it is characterised in that is equipped with plunger in piston, cushion chamber is formed between piston and plunger, nylon is equipped with plunger
Block, piston thread connection piston rod, piston are equipped with the hole communicated with cushion chamber.
In order to further realize the purpose of this utility model, the piston is equipped with the stepped hole communicated with cushion chamber.
In order to further realize the purpose of this utility model, the piston is equipped with the processing hole communicated with cushion chamber,
Processing hole is connected through a screw thread the plug screw of middle with hole.
In order to further realize the purpose of this utility model, connected between the piston and plunger by elastic spring.
Conduction band, axis circle, gear are equipped with order to further realize the purpose of this utility model, between the piston and plunger
Circle.
The utility model can produce following good effect compared with the prior art：The utility model is simple in structure, is applicable in model
Enclose extensively, occupied space is few, good buffer effect, and buffering effect can be quantified and controlled.When oil cylinder leads to oily side pressurization, piston passes through
Stepped hole is oil-filled, and when piston reaches oil cylinder end, the plunger in piston bumps against with oil cylinder end, the hydraulic oil of buffer piston intracavitary
It is discharged fast into logical oily side from throttle orifice, cushioning effect is realized with this.The quantitative control of buffer speed is by adjusting rank
The size and length in terraced hole is realized.
Brief description of the drawings：
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram of the piston of the utility model the first embodiment；
Fig. 3 is the structure diagram of the piston of second of embodiment of the utility model.
Embodiment：Elaborate below in conjunction with the accompanying drawings to the preferred forms of the utility model：
Embodiment 1：A kind of one-way cylinder is without oil pocket buffer structure（Referring to Fig. 1, Fig. 2）, it includes piston 1, nylon block
2nd, plunger 3, piston rod 4, holding screw 5, elastic spring 6, conduction band 7, axis circle 8, baffle ring 9.Plunger 3, piston are equipped with piston 1
Cushion chamber 10 is formed between 1 and plunger 3, is connected between piston 1 and plunger 3 by elastic spring 6, nylon block 2 is filled by extruding
With enter plunger 3 among, between piston 1 and plunger 3 by conduction band 7, axis with circle 8, baffle ring 9 be oriented to and sealed, piston 1 and
It is connected through a screw thread between piston rod 4, it is locking by holding screw 5.A ladder communicated with cushion chamber 10 is processed on piston 1
Hole 1-1 is used for being used for throttling oil extraction in cushion chamber repairing and buffering course.
Operation principle：
When oil cylinder, which leads to oily side pressurization, leads to oil, by stepped hole 1-1 oil inlets in piston 1, by the plunger 3 in buffer unit
Get, due to the effect of elastic spring 6, plunger 3 cannot spin off from piston 1, be full of hydraulic pressure in cushion chamber 10 in piston 1
Oil, hydraulic oil in cushion chamber 10 cannot penetrate into oil cylinder obstructed oily one because axis encloses the sealing function of 8 and baffle ring 9
Side.When piston 1 runs to oil cylinder end, the nylon block 2 on plunger 3 bumps against with oil cylinder end, plunger 3 is returned to piston 1
In cushion chamber, the hydraulic oil in cushion chamber is discharged to logical oily side by stepped hole 1-1, due to the throttling action of stepped hole 1-1
Slow down the movement of oil cylinder piston 1, so as to play cushioning effect.
Embodiment 2：A kind of one-way cylinder is without oil pocket buffer structure（Referring to Fig. 1, Fig. 3）, its structure and principle and implementation
Example 1 is essentially identical, and difference lies in the rank for the oil extraction that throttles in the cushion chamber repairing to buffer unit and buffering course for it
Terraced hole can also be replaced with the structure in Fig. 3, and a hole 1-2 and screw thread 1-3 is processed on piston 1, one is tightened on screw thread 1-3
The plug screw 1-4 of a middle with hole.
Embodiment above is only that the preferred embodiment of the utility model is described, other preferred embodiments
Do not tire out one by one herein and state, and not the scope of the utility model is defined, do not departing from the spirit of the design of the utility model
Under the premise of, various modifications and improvement that this area ordinary skill technical staff makes the technical solution of the utility model should all
Fall within the protection domain that claims of the utility model determine.
