[Problems to be solved by the device]

 According to the present invention, a weight vibration control unit with a fitting insertion portion that has a fitting insertion hole that constitutes a vibration damping device for a down swing weight is fixed in a horizontal state, and further, a vibration damping device with a small hole that has an extremely small friction resistance force. The lower surface of the adjustment unit and the upper surface of the weight control unit are lightly abutted and slidably placed, and the downward swinging weight that rotates 360 degrees has the restoring force that the weight itself has to stop. It was designed so that it could be made to stand still reliably and quickly without obstruction.

Further, the support rods protruding from the upper portion of the weight are fitted into the fitting insertion holes of the upper and lower swing control portions and the fitting portions of the lower weight swing control portion, respectively, and the swing of the support rods is caused. This is intended to prevent biasing due to deviation and speed up the rest time of the weight.

[0013]

[Action]

 Since the operations of the inventions of claims 1 to 4 of the present invention are common, they will be described collectively.

When using the device of the present invention, for example, when looking at the vertical degree of a standing column, the vernier scale above and below the main scale to which the swing control control device for the downward swing weight is mounted is installed from the floor to the ceiling. Extend and align the marking line formed on the side wall of the vernier scale.

Further, when the studs are to be erected, the floor and the ceiling are marked with the marking line of the case body.

After that, the above-mentioned main scale and vernier scale are adjusted to expand and contract, and are brought into close contact with the side surface portion of the measured column. At that time, the upper part of the down swing weight is attached to the fit insertion part of the down swing weight control part with the fitting insertion part, the small hole of the swing down adjustment part, and the fit insertion hole of the upper and lower swing motion control part. A support rod that projects from and is connected to the hanging thread penetrates.

The anti-vibration adjusting unit, which is made of, for example, an extremely lightweight plastic plate material, is slid above the anti-vibration anti-vibration control unit of the weight set as described above, and is always in a mounted state. .

Further, a collar portion attached to the support rod is interposed in a gap portion of the upper / lower swing control unit so as not to be in close contact with the upper / lower swing control unit.

However, the weight is rotated in various directions through the support rod (for example, at most 360 degrees), and collides with the inside of the fitting insertion portion and the fitting insertion hole of each mechanism several times. Gradually enter the stationary state while repeating.

By the way, since the anti-vibration adjusting section which is placed above the anti-vibration control section of the plumb bob weight and is in a sliding state is extremely lightweight, the resistance force due to friction is small. The so-called resting force that the weight tries to stop is not disturbed. The anti-swing adjustment unit works only a small frictional force on the upper part of the anti-swing control unit of the downswing weight, so that the weight can be stopped smoothly without biasing the rest of the weight. Excuse me.

Further, the present invention limits the swing of the support rod during the fitting by the fitting hole of the upper and lower swing control section, and the swing control section of the down swing weight positioned below and the swing control section. The weight can be stopped still more quickly due to the friction with the stop adjustment unit.

Regarding the shape of the anti-vibration adjusting section, as a basic condition, a material that is lightweight and has an extremely small resistance value when friction with the lower weight control section is used. Therefore, a plastic plate material having a shape as shown in the drawing may be used.

[Effect of device]

 The present invention has the following effects.

According to the present invention, a weight vibration damping control unit having a fitting insertion portion is horizontally fixed to a rear side wall portion of a main scale, and a weight vibration damping adjustment portion with a small hole is always provided above the fitting insertion portion. Slide and place it, and insert the support rod with hanging thread protruding from the upper part of the weight into the fitting insertion part of the weight vibration suppression control part and the small hole of the vibration suppression adjustment part. Since the weight that swings freely in the front-rear and left-right directions is made to stand still while minimizing the resistance force generated when the lightweight anti-vibration adjustment section rubs, the weight should be kept in a biased state. It has nothing to do with it, and has the advantage of being able to stand still very smoothly.

Further, according to the present invention, since the collar portion fitted to the support rod is interposed in the gap portion of the upper and lower swing control section, even if the entire measuring instrument is overturned, the weight can largely move. Absent.

Further, according to the present invention, the upper / lower swing control section is attached in parallel with the weight swing control section, and the insertion hole of the upper / lower swing control section and the weight swing control section are attached. Since the insertion and insertion parts of the weight are made to have the same size and overlapped with each other, the stationary of the weight is alleviated at the same time as the collision caused when the supporting rod is swung, and the weight is reduced. It also has the advantage that it can perform surely and swiftly in synchronism with the function of the anti-vibration adjusting section.
