Description
Technical field
The utility model relates to a kind of quartering hammer technical fields, more specifically, it relates to a kind of reversal valve and cylinder body oil
The cross-linked structure on road.
Background technique
It is equipped with reversal valve and cylinder body in traditional quartering hammer, there is corresponding oil circuit between reversal valve and cylinder body, in reversal valve
Oil circuit lead directly in cylinder body, although reversal valve is connected to cylinder body in this way, be easy to appear oil spilling, and be easy to appear
Oily situation oil circuit occurs.
Utility model content
In view of the deficienciess of the prior art, being not easy down oil the purpose of this utility model is to provide one kind and being not in
The reversal valve of oil spilling and the cross-linked structure of cylinder body oil circuit.
To achieve the above object, the utility model provides following technical solution: a kind of friendship of reversal valve and cylinder body oil circuit
It is coupled structure, including cylinder body, is equipped with plunger shaft, the lock chamber being connected to plunger shaft and the installation being placed on cylinder body in the cylinder body
Slot is equipped with the first oil duct in the mounting groove, and the second oil duct is equipped in the plunger shaft, and third oil duct is equipped in lock chamber, the
One oil duct is equipped with the first Oil Guide road, which connect with third oil duct, and first Oil Guide road is by with first
Oil duct is connected go side to end inclination is connected to third oil duct, and described cylinder body one end is equipped with sluice way, second oil duct and third
The second Oil Guide road being connected to sluice way is equipped on oil duct.
By using above-mentioned technical proposal, using the second oil duct being arranged in plunger shaft and lock chamber and third oil duct is used to
Install by the oil in the first Oil Guide road on the first oil duct, and the first Oil Guide road is arranged to it is skewed so that work when
It waits, is fallen in oil to the first oil duct to third oil duct, need certain height limitation and inclined limitation, further avoid
Oily situation occurs, and recycles the second oil duct and third oil duct to carry out the second Oil Guide road connecting with sluice way, leads by second
Oil duct forming circuit, and the effect of secondary oil storage, further prevent should oil inlet and there is down oily situation and occur, and
Plunger shaft can be given simultaneously and lock chamber plays internal lubrication effect.
The utility model is further arranged to: the second oil duct diameter is less than third oil duct diameter.
By using above-mentioned technical proposal, third oil duct diameter is less than by the second oil duct diameter, oil circuit can be accelerated and followed
Ring, and certain buffering is played by being relatively large in diameter third oil duct, it reduces oily phenomenon and occurs.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is the oil channel structures schematic diagram of the utility model embodiment.
Specific embodiment
The utility model embodiment is described further referring to figs. 1 to Fig. 2.
A kind of cross-linked structure of reversal valve and cylinder body oil circuit, including cylinder body 101, the cylinder body 101 is interior to be equipped with plunger shaft
102, the lock chamber 201 being connected to plunger shaft 102 and the mounting groove 301 being placed on cylinder body 101 are equipped in the mounting groove 301
First oil duct 32, the plunger shaft 102 is interior to be equipped with the second oil duct 13, is equipped with third oil duct 22, the first oil duct 32 in lock chamber 201
Be equipped with the first Oil Guide road 401, which connect with third oil duct 22, first Oil Guide road 401 by with
First oil duct 32 is connected go side to end inclination is connected to third oil duct 22, and described 101 one end of cylinder body is equipped with sluice way 501, described
The second Oil Guide road 502 being connected to sluice way 501 is equipped on second oil duct 13 and third oil duct 22.
By using above-mentioned technical proposal, using the second oil duct 13 and third are arranged in plunger shaft 102 and lock chamber 201
Oil duct 22 is used to install the oil for passing through the first Oil Guide road 401 on the first oil duct 32, and the first Oil Guide road 401 is arranged to tilt
Shape, so that at work, being fallen in oil to the first oil duct 32 to third oil duct 22, needing certain height limitation and incline
Oblique limitation further avoids down oily situation from occurring, and the second oil duct 13 and third oil duct 22 is recycled to carry out and sluice way 501
Second Oil Guide road 502 of connection is formed into a loop by the second Oil Guide road 502, and the effect of secondary oil storage, is further prevented
Should oil inlet and there is down oily situation and occur, and plunger shaft 102 can be given simultaneously and lock chamber 201 plays internal profit
Sliding effect.
The utility model is further arranged to: 13 diameter of the second oil duct is less than 22 diameter of third oil duct.
By using above-mentioned technical proposal, 22 diameter of third oil duct is less than by 13 diameter of the second oil duct, oil can be accelerated
Road circulation, and certain buffering is played by being relatively large in diameter third oil duct 22, it reduces oily phenomenon and occurs.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field
Art personnel carry out common variations and alternatives within the scope of technical solutions of the utility model should be included in the guarantor of the utility model
It protects in range.
