Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is used when mounting holes such as lamps, distribution boards (working power supply box), and equipment to the mounting holes of the pedestal and columns, and mounting with mounting bolts, washers, and nuts. It relates to a temporary fixing pin (jig).

[0002]

[Prior art]

 Conventionally, there are many lighting fixtures at high positions in each factory, heavy distribution boards supported by 3 to 4 people, installation of equipment, etc. Other pipe flanges are connected while suspended at high positions. For mounting work such as mounting, the mounting holes are aligned with the mounting holes of the pedestal, columns, etc. while supporting these mounting objects, and are directly mounted with bolts and nuts.

[0003]

[Problems to be solved by the device]

 This kind of mounting work involves handling heavy objects in an uncomfortable posture with a congested place such as another work piece, and in the case of connecting a light fixture or a pipe flange of a pipeline, it is a high place. Since there are many cases, heavy work for a long time and an unreasonable posture make the work troublesome and tired, and the back tends to be painful.

For example, as shown in FIG. 6 (A), when mounting a medium or small distribution board, it is supported by about three or four people, and the other person directly supports the mounting hole where the mounting object and the mount match. The mounting bolts, washers, and nuts are used to secure to, and heavy objects must be held and supported until the end of mounting.

Further, as shown in FIG. 6 (B), two people perform the work of mounting the lamp in the factory. This is usually when one person installs a 40W light fixture, put the light fixture on the shoulder on the scaffold, hold the bolt with the hole with one hand, and tighten the washer and nut with one hand, so drop the washers and nuts well. However, the work is difficult and requires a certain amount of skill. In addition, there is a safety problem when one person works by this method, so two people are usually forced to work. ing.

An object of the present invention is to develop an improved jig for solving such a problem so that the mounting work can be performed easily, safely and promptly.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the toggle pin of the present invention is provided with a split groove at the tip of a shaft portion provided with a collar at one end, and the center of gravity is biased in the split groove to pivotally support the rotary piece. The spring is fitted between the shaft and the washer and between the washer and the collar, and the rotating piece is held in a straight line with the shaft or at a right angle to the shaft by the washer and the spring. It is something that is done.

[0008]

[Action]

 In the product of the present invention, the washer is pushed by aligning the mounting holes of the mounting base with the mounting holes provided in the mounting seat of the mounted object and inserting the tip of the shaft portion of the toggle pin of the present invention into these mounting holes. Since the spring is compressed, the rotating piece rotates due to the deviation of the center of gravity around the pin center, and at the same time, the repulsive force of the spring pushes one end of the rotating piece on the rear surface of the mounting base, so that the rotating piece is perpendicular to the shaft. The T-shaped posture is retained and locked, the mounting seat can be fixed to the mounting base, and even if the weight of the mounting object is applied, it is locked in the T-shape, so there is no risk of disengagement. In addition, the force of the spring adjusts to changes in the thickness of the mounting body and mounting portion, and the body can be temporarily fixed with one touch.

Further, the attached toggle pin can be easily removed by pushing the flange side of the shaft portion, causing the washer to retract against the spring, and rotating the rotating piece in line with the shaft portion. Sequentially pass through the fully tightened mounting bolts, fit the flat washer and spring washer, and tighten the nut to secure.

To explain an example of its use, when installing a distribution board in a factory, as shown in FIG. 4, the distribution board (box) is supported by about three workers, and The washer moves against the spring by aligning the mounting holes with the gantry and inserting the toggle pin with one hand into the mounting hole with one hand, and the washer moves against the spring. It is rotated at right angles to the shaft part around the support pin, and the rotating piece is locked by the force of the spring on the back surface of the pedestal while maintaining a T-shaped posture with the shaft part, and attached to the main body with the collar and rotating piece. The part can be clamped and temporarily fixed. After that, pull out the toggle pins in sequence as described above and tighten them with the mounting bolts, washers, and nuts. At this time, it is not necessary to support and support heavy objects.

【Example】

 1 and 2 are a perspective view and a plan view of a toggle pin 1 according to the present invention, in which an end of a shaft portion 4 having a flange 3 with a flat knob portion 2 at one end is shown. A split groove 5 is provided in the center of the flat pivot piece 6 having a head portion 6'having substantially the same diameter as the shaft portion 4 and a heavy weight at the tip. The spring 9 is pivotally attached at 7, and a spring 9 is fitted between the washer 8 and the washer 8 and the collar 3, and both ends of the spring 9 are fixed to the collar 3 and the washer 8. Is maintained by a washer 8 and a spring 9 in a T-shaped posture in a straight line with the shaft portion or at a right angle to the shaft portion 4.

FIG. 3 shows a state of connection by the toggle pin 1, in which the attachment hole 13 of the support 12 is aligned with the attachment hole 11 of the support or the pedestal 10 and the toggle pin 1 is inserted to fix the collar 3 side. When pushed, the washer 8 retracts against the spring 9 and is disengaged from the rotating piece 6, so that the rotating piece 6 rotates about the pivot pin 7 as a fulcrum due to the biased gravity of the head 6 '. At the same time as taking a T-shaped posture perpendicular to the shaft portion 4, the column or pedestal 10 and the attachment 12 are clamped and fixed by the collar 3 and the rotating piece 6 by the force of the spring.

FIG. 4 shows a work state when the distribution board 14 is attached to a predetermined support stand 15 in a factory. About three people hold the distribution board 14 of the work power supply and support it. The mounting hole 17 of 6 is aligned with the mounting hole 18 of the column base 15, and the operator inserts and pushes in the toggle pin 1 with one hand. Both are temporarily fixed by the rotating piece 6.

In addition, in the case of mounting a number of electric lamps in each factory at a high position as shown in FIG. 6B, an operator who has stepped up on a stepladder supports the electric lamps with one hand and attaches them. And push the toggle pin 1 into the matching mounting hole from below with the other hand. As described above, the rotating piece 6 rotates at a right angle to the shaft portion 4 to engage the T-shape. Both can be temporarily stopped simply by stopping.

After the temporary fixing, the washer 8 is moved by pushing the flange side of the shaft portion 4. Therefore, when the rotating piece 6 is returned to the shaft portion 4 in a straight line, the toggle pin 1 is moved forward by the force of the spring 9. Since it pops out to the front and can be easily removed, it is fixed by using washers and nuts through the mounting bolts. Although the case of temporary fixing and fixing with bolts has been described, some attachments can be sufficiently attached only by attaching the toggle pin 1, and the present invention is not limited to the above, and can be used in a very wide range.

FIG. 5 shows a case of connecting the pipe 19 at a high position. It is also possible to align the holes of the pipe flanges 20 and 20 and temporarily fix using the toggle pin. In this case, Positioning by inserting the toggle pin, and bolt fixing by replacing it can be done easily, etc.Because the installation can be done with both hands, there is no danger of the washer or nut falling, and work can be done easily even when facing up .

[0017]

[Effect of device]

 The present invention requires an unreasonable posture with places where other work is congested, such as the installation of high-level lighting fixtures in each factory and the installation of small and medium-sized distribution boards (working power supply boxes). When mounting a heavy object, the toggle pin of the present invention can be rotated by the biased gravity due to the biased gravity by the operator holding the heavy object and pushing it into both the mounting holes of the mounting body and the mounting part with one hand. It moves to maintain a T-shaped posture at right angles to the shaft, and at the same time, the washer and the rotating piece clamp the two parts, the body and the mounting part, by means of spring pressure, and temporary fixing is completed with one touch. The number of workers can be reduced, and the time for handling heavy objects can be shortened, which significantly reduces the burden on workers and the working time.

Further, the attached toggle pin can be easily removed by pushing the flange side of the shaft portion and rotating the rotating piece in a straight line with the shaft portion.Thus, a flat washer, a spring washer, and a nut are inserted through the mounting holes through the bolts. It is easy to install and does not need to support heavy objects or shoulders as in the past, and you can be released from an unnatural and difficult posture. Also, in the mounting work at a high position, there is no need to worry about dropping parts, and the mounting work can be performed easily, safely and quickly, and the work can be simplified. In addition, the spring can be used to adjust the thickness of the attachment body to adjust the attachment, and it can be used not only for temporary fixing but also for ordinary wide-range attachment.
