Background technique
Hydraulic cylinder is very important a component for hydraulic machinery, and one is played the part of in entire hydraulic machinery and is held
The role of units, hydraulic cylinder is exactly that hydraulic energy is converted into mechanical energy in whole process；Its structure is simple, reliable operation, uses
It when realizing reciprocating motion, can remove deceleration device from, and not have drive gap, and movement is steady, therefore in the liquid of various machinery
It is used widely in pressure system.However the existing connector that connected pipes are used on the cylinder body of hydraulic cylinder, typically adopt
With the mode of welding on cylinder wall welding point, then by connector connected pipes, as shown in Fig. 1；Its there are the shortcomings that
Be: if connector is broken, cannot replace, and the orientation of connector be also it is nonadjustable, between hydraulic cylinder and oil pipe
Installation bring certain inconvenience.
Summary of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of assembly is simple, direction can
Adjust, be easily installed the hydraulic cylinder of oil pipe.
The purpose of this utility model is completed by following technical solution, this hydraulic cylinder include cylinder body, cylinder bottom seat,
Piston rod, the cylinder body and cylinder bottom seat integrally connected form, and piston rod is located in cylinder body and moves back and forth, the cylinder
Through-hole there are two being set on the casing wall of body, and two connectors for connected pipes are separately installed with by two through-holes；It is described
One end of connector be equipped with external screw thread, the through-hole wall on casing wall corresponding with the external screw thread is equipped with internal screw thread, and described connects
Head is in mating connection by external screw thread and the internal screw thread on through-hole wall；Internal screw thread on the external screw thread and through-hole wall of the connector
Between be coated with fastening glue.
Preferably, described externally threaded connector end that is equipped with is cone-shaped, the through-hole matched with the tip side is
Bellmouth；And it should have and be connected and fixed by way of taper thread sealed connection between externally threaded connector and through-hole.
Preferably, the other end of the connector is equipped with connector, and it is connected and fixed by the connector with oil pipe.
Preferably, there are two the connector sets, one be straight joint, one be bent sub, it is the straight joint, curved
On the through-hole that the casing wall that connector can be arbitrarily installed in cylinder body is equipped with.
Preferably, the fastening glue is screw thread glue.
The utility model has the following beneficial effects: by the through-hole for being provided with screw thread on cylinder wall, so that installation
The connector of oil pipe can orientation be adjustable is mounted on cylinder wall, and is coated with screw thread glue at the screw thread that the two is connected；With structure
Novel, replacement facilitates, is easily installed, the advantage that direction is adjustable.
Detailed description of the invention
Fig. 1 is the existing hydraulic cylinder structure schematic diagram with connector.
Fig. 2 is the hydraulic cylinder structure schematic diagram with connector of the utility model.
Fig. 3 is the part section enlarged structure schematic diagram at the A of Fig. 2.
Label in attached drawing is respectively as follows: 1, cylinder body；2, cylinder bottom seat；3, piston rod；4, connector；5, fastening glue；6, oil pipe；
11, through-hole；41, straight joint；42, bent sub；43, connector.
Specific embodiment
Below in conjunction with attached drawing 2, the present invention will be described in detail: the present invention includes cylinder body 1, cylinder bottom seat 2, piston rod 3,
The cylinder body 1 and 2 integrally connected of cylinder bottom seat form, and piston rod 3 is located in cylinder body 1 and moves back and forth, the cylinder body 1
Casing wall on set there are two through-hole 11, and be separately installed with two connectors 4 for connected pipes by two through-holes 11；Institute
The one end for the connector 4 stated is equipped with external screw thread, and 11 wall of through-hole on casing wall corresponding with the external screw thread is equipped with internal screw thread, described
Connector 4 by external screw thread and the internal screw thread on 11 wall of through-hole it is in mating connection；There are two the connector 4 is set, one is straight
Connector 41, one are bent sub 42, and the casing wall that the straight joint 41, bent sub 42 can be arbitrarily installed in cylinder body 1 is equipped with
Through-hole 11 on；I.e. straight joint 41, bent sub 42 can be exchanged arbitrarily or can be arbitrarily installed in one of them of two through-holes 11,
It is strong with interchangeability, in the case that oil pipe is more difficult be mounted on, only need to change the shape of lower contact 41 or adjust lower direction
Smoothly installation oil pipe brings certain convenience to construction.
As shown in Fig. 3, described externally threaded end of connector 4 that is equipped with is cone-shaped, and what is matched with the tip side is logical
Hole 11 is bellmouth；And it should have and be connected and fixed by way of taper thread sealed connection between externally threaded connector 4 and through-hole 11；
It is by the advantages of taper thread connection type: it is good to neutrality, so that connector 4 is not easy skew during the installation process, and seal
Performance is more prominent.
