Description

[Detailed Description of the Invention] This invention relates to a mounting device for a pivot, that is, a suspension shaft, suspended between opposing surfaces such as inner walls of a housing.

Generally, in the internal structure of equipment assembled into a housing, such as a public telephone or a measurement display, it is necessary to utilize the space within the housing three-dimensionally to accommodate as many components as possible. , a structure is adopted in which middle plates are laid out in multiple rows within the casing, and sub-assemblies are attached to the entire surface of each middle plate. There is a method in which the area around the center plate is secured with screws to the frame of the case, but with this method, maintenance work on the equipment becomes troublesome because the center plate must be removed one by one during repairs, etc. There is a drawback.

Additionally, for the purpose of facilitating maintenance work, there is a method in which the middle plate is attached to the casing so that it can be opened laterally, allowing required subassemblies to be exposed to the outside with a single touch. It is troublesome to attach and detach the shaft that supports the plate from the casing, and this has the disadvantage that it tends to be more inconvenient when replacing the entire middle plate.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and the purpose of the present invention is to provide a suspension shaft mounting device that can be attached and detached with a single touch between opposing surfaces such as the inner walls of a housing. It's about doing.

The structure of the present invention for achieving the above object will be explained with reference to drawings corresponding to embodiments.

That is, the present invention provides a bearing in which one end of the pivot 4 is supported by being dropped into one inner wall of the casing 1, in a device for attaching the pivot 4 to the inner wall, which is suspended between opposing surfaces such as the inner wall of the casing 1. The recess 7a is formed, and the other end 4a of the pivot 4 is formed into a tapered shape.The other inner wall of the housing 1 is made of a long spring plate, and the diameter of the pivot 4 is formed on the plate surface. A bearing plate 9, which has a slot 9c with a width smaller than that of the original size, and a bearing hole 9a communicating with the slot 9c, is fixedly mounted so as to be suspended from a wall surface, and one end of the pivot 4 is inserted into the bearing recess. 7a, the tapered portion of the pivot 4 is fitted into the slot 9c, and the pivot 4 is raised up against the elasticity of the bearing plate 9 using the slot 9c as a guide. The suspension shaft mounting device is characterized in that the circumferential surface of the pivot shaft 4 in contact with the tapered portion is formed so as to be fitted into the bearing hole 9a.

Next, the operation of the present invention will be explained.

With one end of the pivot 4 engaged in the bearing recess 7a, the tapered portion of the other end of the pivot 4 is fitted into the slot 9c of the bearing plate 9, and the pivot 4 is erected using the slot 9c as a guide. By raising the bearing plate 9, the tapered portion pushes the bearing plate 9 and bends elastically. When the tapered portion reaches the bearing hole 9a, the pressing force is released and the bearing plate 9 returns to its original position. The peripheral surface fits into the bearing hole 9a. As a result, both ends of the pivot shaft 4 are supported by both inner walls of the housing 1.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

The housing to which the mounting device of the embodiment is applied has one side, that is, the first side, as shown in FIGS.
A box body 1 with an open front on the front right side in the figure, and a bread-shaped top lid 2 hinged to the right side of the opening edge of the box body 1
At the middle of the depth of the inner wall of the box body 1, a middle plate 3 made of a square plate is extended.

A pivot shaft 4 passes through the collar-shaped projections 3a formed on the upper and lower sides of the left end of the middle plate 3, and the pivot shaft 4 is fixed with a screw 5 inside each of the upper and lower penetrating portions. In addition to being prevented from coming out by ring 6,
The upper end portion 4a of the pivot shaft 4 is formed into a tapered shape such as a conical shape with a truncated top.

Further, a disc-shaped receiving plate 7 is welded to the left side of the bottom surface of the box body 1, and a bearing recess 7a with an enlarged diameter opening is formed in the center of the upper surface of the receiving plate 7. The lower end of the pivot 4 is supported and bearing in the recess 7a by being depressed.

In addition, a block-shaped base 8 is welded to the ceiling surface of the box body 1 at a location opposite to the receiving plate 7.
A base of a bearing plate 9 made of a longitudinal spring plate is fixed to the lower surface of the base 8, and a pivot 4 is located in the middle of the plate surface of the bearing plate 9 projecting forward from the base 8.
A bearing hole 9a to be fitted externally is opened, and a slot 9c having a width smaller than the diameter of the pivot 4 is opened between the bearing hole 9a and the tip end 9b so as to communicate with the bearing hole 9a. , an obliquely upward folding step is formed in the middle of the plate surface, and the height of the tip portion 9b is increased.

As shown in FIG. 4, the height relationship between the upper end of the pivot 4 and the bearing plate 9 in the assembled state is that the part slightly lower than the upper end 4a of the pivot 4 fits into the bearing hole 9a, It is supported.

Next, in the upper and lower two places on the inner surface of the right side of the front cover 2,
Each base 10a, 11a of the hinge arms 10, 11
The two arms 10 and 11 are formed in the same manner, except for the presence or absence of a long hole, which will be described later. First, the upper arm 10 will be explained.

The hinge arm 10 is formed by the above-mentioned base 10a, a projecting part 10b made of a long plate, and ears 10c projecting in a U-shape from the upper and lower edges of the tip of the projecting part 10b. A horizontal elongated hole 10d is formed near the upper edge of the tip of the protruding portion 10b.

Thus, the ear portion 10c circumscribes the upper and lower brim surfaces of the receiving plate 12, which has a U-shaped cross section and is welded to the side plate 1a of the box body 1 close to the opening side, and also extends to the hinge shaft 13 vertically suspended between the brim surfaces. It is attached to the shaft.

In addition, the formation mode of the lower hinge arm 11 is as follows.
It is exactly the same as the hinge arm described above, except that the elongated hole is not provided in the overhang.

In addition, a torsion coil spring 14 is wound around the upper hinge shaft 13, and a short pin 14a at the lower end of the spring 14 is hooked on the tip edge of the arm extension 10b. The long pin 14b at the upper end of the pin 14 projects through the long hole 10d, and has a rounded tip. In the illustrated normal position, the spring 14 is in a free state or has a slight preload elasticity, and the long pin 14b is just touching the edge of the long hole 10d.

In this way, the front cover 2 can freely rotate to open and close to the right around the hinge shaft 13, and the middle plate 3 can freely rotate around the pivot 4 when the front cover 2 is open. It can be rotated to open and close to the left, but when the middle plate 3 closes, it is closed by colliding with a stopper 15 made of an L-shaped plate welded to the right side of the ceiling surface of the box body 1. The component is positioned.

Here, the operation of the mounting device of the embodiment configured as described above and the intermediate plate 3 held by the device will be explained with reference to FIGS. 4 and 6b.

To attach the pivot shaft 4 as a suspension shaft to the box body 1, the lower end of the pivot shaft 4 is dropped diagonally into the bearing recess 7a of the support plate 7, and then the upper end portion 4a of the pivot shaft 4 is attached to the box body 1.
If it stands up in the depth direction of the inner space, its upper end 4a
first hits the lower surface of the tip 9a of the bearing plate 9 and pushes the tip 9a open against elasticity, and then, when it reaches the slot 9c, the top of the upper end 4a fits into the slot 9c. Furthermore, the upper end portion 4a moves while pushing open the inclined step portion of the slot 9c, and when it finally reaches the bearing hole 9a, the bearing hole 9a overcomes the lower end of the tapered upper end portion 4a, so that the bearing plate 9 returns to a free state due to elasticity, and the periphery of the pivot 4 is fitted into and supported by the bearing hole 9a.

In addition, when removing the pivot 4 from the box body 1, after manually pushing open the tip 9b of the bearing plate 9, tilt the pivot 4 forward and pull it out obliquely upward. can be carried out with one-touch operation, and when the pivot 4 is assembled, its upper and lower ends are supported in the bearing hole 9a and the bearing recess 7a, respectively, so that the pivot 4 is securely attached to the box. attached to body 1;

In addition, even if there is some slack when attaching the pivot 4, the slack will be shifted to one side by the positioning action (described below) when the middle plate 3 is closed, so it will not cause malfunction of the members attached to the pivot 4. It has no effect.

Specifically, when the front cover 2 is opened (FIG. 6b), the rounded tip of the long pin 14b of the spring 14 attached to the hinge arm 10 elastically presses the swinging end of the middle plate 3. As a result, the middle plate 3 comes into close contact with the stopper 15, and at the same time, the slack of the pivot 4 is also shifted toward the depth side.

According to the suspension shaft mounting device according to the present invention, both ends of the suspended pivot shaft 4 are dropped into the bearing recesses 7a provided in the suspension wall, and the bearing holes of the bearing plate 9 fixed to the suspension wall are provided. Since it is configured to be supported by push-fitting into the suspension shaft 9a, the suspension shaft 4 can be easily attached and detached, and this has the effect of making maintenance work for the assembly, etc. held by the suspension shaft 4 more efficient.
