Problems to be Solved by the Invention
The blackout laser device described in Japanese Patent No. 2943 supports a laser tube (a helium gas laser type 1 mmW rectilinear deflection type disposed in a cylindrical protective tube made of aluminum) so as to be automatically vertical by a gyro. The laser tube is placed inside the windshield suspended from the head, and the windshield has a plurality of screw-in fixtures for fixing the protection tube of the laser tube, so the laser tube can be destabilized. Although it can be prevented, apart from the power supply connection, and since a plurality of fixtures must be rotated individually, the work is very troublesome.

Further, in the blackout device described in Japanese Patent Application Laid-Open No. Hei 6-297350, since the weight-supported support for supporting the laser projection device is in a free state, the device is transported and transported to the site. There was a problem in that the laser projection device could be damaged by collision with the inner wall or support of the cover during transportation, or when moving from place to place, or the pivot could be damaged, causing the projection of the vertical marking line to be out of order. .

The present invention provides a blackout laser device with a lock mechanism that can easily and reliably lock and release a weight-supported support that supports a laser projection device only by turning on and off a switch. It is intended to provide.

[0006]

According to the present invention, there is provided a blackout laser device with a lock mechanism, comprising: a rod having a central axis horizontal to the optical axis of a laser beam, at a central portion of a horizontal frame supported by a column erected on a base; A support that supports and fixes a laser projection device provided with a lens is pivotally supported by a pivot shaft so as to be capable of swinging like a weight in a vertical plane, and is radiated in a vertical plane direction through a rod lens from the laser projection device. In a blackout laser device that emits a light beam from the light emitting slit of the cover body to the outside, a support plate for an operating body is fixed to the lower surface of the horizontal frame, and both sides of the support plate for the operating body are fixed to the side walls. A bifurcated support lock body provided with an operation lever so as to protrude to a position that does not hinder the passage of laser light from the light emission slit of the body of the cover body, and is pivotably supported. A switch that is turned ON by pressing is fixed to one side wall of the holding body lock or the lower surface of the horizontal frame, and the pulling direction is changed with a straight line passing through the pivot point of the support locking body as a thought point. The lock body for the support and the horizontal frame are connected by a tension spring, and the switch of the laser projection device is turned ON by the operation lever,
A blackout laser device with a lock mechanism including a switch operation / lock mechanism that locks the swing of the support along the vertical plane by the support lock body by the OFF operation at the same time as being turned off. .

[0007]

When the operating lever is operated in one direction, the switch is pressed and maintained by the operating force and the holding force of the tension spring, and the switch of the device is operated. When the operating lever is operated in the opposite direction, it will be turned off.At the same time, the tension spring and the operating force will cooperate, and the support that supports and fixes the laser projection device will be sandwiched between the forks of the support lock. Locked. For this reason, in the OFF state of the device, the support is always locked and does not move, and the laser projection device collides with the inner wall and the support of the cover during handling such as transportation, transportation, movement, etc. Failures, such as damage and misalignment of the projection of the vertical marking line, are eliminated.

According to a second aspect of the present invention, a horizontal through-hole is formed below the pivotal position of the support in a direction along the vertical plane on the vertical center line of the support, A balance rod is loosely fitted in the horizontal through-hole to adjust and correct the imbalance in weight in the vertical direction caused by providing the laser projection device on the support by moving the balance rod to the left or right. Can be.

Of ON, performs OFF, OFF
During operation, the support locking member locks the support. Therefore, in the OFF state of the laser projection device, the support is always and securely locked and does not move, and the laser projection device collides with the inner wall and the support of the cover and is damaged during handling such as transportation, transportation, and movement. In addition, it is possible to provide a lock-equipped ink jetting device with excellent durability, in which a failure such as damage to a pivot portion and a deviation in projection of a vertical ink jetting line is eliminated.

In addition, a separate mechanism for locking the support is provided to perform another operation. Since the lock can be performed without uneconomical and inefficient operations, the operation is simple, and when the switch is turned off, the lock is always performed. Since the lock is always released, the lock can be quickly handled without being conscious of locking and unlocking, which is very convenient, and the stakeout workability is also improved.

As described in the second aspect, a horizontal through hole is formed below the pivotal position of the support on the vertical center line of the support and in the vertical plane direction. By loosely fitting the balance rod into the through-hole, the imbalance in the vertical direction caused by the provision of the laser projection device on the support is corrected by adjusting the movement of the balance rod to the left or right, and the laser beam is adjusted vertically. The radiation can be radiated to the line, so that accurate ink marking can be performed.
