Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a cylinder device, and more particularly to a cylinder device that is used with attached equipment such as a position detection switch attached to the outer periphery of a polygonal main body.

[Background Art] For example, in a cylinder device that performs a predetermined work to the outside through the reciprocating motion of a piston driven by the action of fluid pressure, the position of the piston inside the main body is grasped from the outside and the predetermined work is performed. In order to transmit information to control equipment, etc., a position detection switch is attached to the outer periphery of the cylinder device body, which is sensitive to a magnet etc. that is integrally attached to the piston. In some cases, the system may be configured to facilitate smooth coordination with the system.

Conventionally, the method for installing the position detection switch as described above on the outer periphery of the cylinder device is to surround the cylinder body and the position detection switch with a steel strip, for example, and to attach the position detection switch to the outer periphery of the cylinder device body. It is conceivable to configure the switch so that it is tied in place, but the route of the cord connected from the outside of the position detection switch becomes cluttered and undefined, which detracts from the aesthetics of the cylinder device. There are problems such as increased space.

Furthermore, in cases where the cylinder device main body has a polygonal cross-section and is installed by bringing one side of the cylinder device into close contact with a predetermined mounting surface, the steel strip surrounding the cylinder device main body is connected to the main body and the mounting surface. There are also problems such as the fact that the cylinder device is sandwiched between the parts, resulting in a gap and incomplete adhesion, making the installation of the cylinder device unstable.

[Purpose of the invention] An object of the invention is to provide a cylinder device to which accessory equipment can be attached without spoiling the aesthetic appearance.

Another object of the present invention is to provide a cylinder device that can reduce the space required for routing a cord connected to an accessory device.

Still another object of the present invention is to provide a cylinder device that can be stably fixed to a mounting surface of a desired object with attached equipment attached thereto.

[Summary of the invention] The cylinder device of the present invention has a mounting groove formed by axially cutting grooves having an L-shaped cross section in close proximity and symmetrically on at least one surface of the outer circumference of a main body having a polygonal cross section. A desired accessory device is fitted and fixed in this mounting groove, and a cord connected to the accessory device is routed within the mounting groove.

[Function] According to the above-described cylinder device of the present invention, the cord connected to the accessory device to be attached is stored in the attachment groove, so that the routing route of the cord does not become irregular and disorderly. Ancillary equipment can be attached without spoiling the aesthetics, and the space required for cord routing can be reduced.

Furthermore, since the desired accessory device is fitted and fixed in the mounting groove, there is no need to attach a steel band to surround the cylinder body and secure the accessory device, and with the accessory device attached, the desired accessory device can be fixed. The cylinder device can be reliably fixed tightly to the mounting surface of the object.
