Abstract

PURPOSE:To rapidly unify two boxes containing electronic component assemblies so as to be freely opened or closed. CONSTITUTION:In a tilt unit connecting a first box 1 with a second box containing assemblies composed of electronic components to be freely opened or closed, a cylindrical hole 3b having a specified depth is provided in the inside of the end face 3a of the shaft 3 inserted into the connection hole 2a of the second box 2. In the cylindrical hole 3b, a compression spring 4 and a movable member 5, on which a sliding face 5a is formed at the front end thereof, are provided. When the end 1c of the first box 1 abuts on the sliding face 5a, the movable member 5 is transferred while compressing the compression spring 4 in the cylindrical hole. And when it coincides with the connection hole 1a of the first box 1, the movable member 5 is pushed out into the connection hole 1a by the compression spring 4. Accordingly, it is not necessary to do work while positioning and hence, man-hours of the work can be reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for assembling two housings for housing electronic equipment components such as personal computers and word processors. The present invention relates to a tilt unit that can easily attach two housings.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
And connecting holes 1a, 1b and 2a, 2b with the second housing 2
The tilt unit 13 and the support component 14 were inserted and assembled to each other. FIG. 5 is a perspective view showing the external structure after assembly. The first housing 1 and the second housing 2 assembled in this way have a structure that opens and closes in the direction of the arrow with the tilt unit 13 and the support component 14 as a fulcrum.

Assembling procedure is as follows. First, as shown in FIG. 5, the housing 1 and the second housing 2 are aligned at the hinge portions A and B (), and the supporting component 14 is screwed into the second housing. Attached from the inside of the body 2 (), determine one position of the opening and closing fulcrum of the first casing 1 and the second casing 2 at the hinge portion A,
Next, the tilt unit 13 is attached from the inside of the second housing 2 with the screw 16 (), and the other position of the opening / closing fulcrum of the first and second housings 1 and 2 is determined by the hinge portion B. Was done by

[0004]

In such a conventional tilt unit, when the two housings are connected, it is necessary to align the mounting positions of the two housings, while maintaining the aligned state. Since it is necessary to turn over the two casings and attach the tilt unit from the inside of the second casing 2, a large number of man-hours are required.

The present invention solves such a problem, and an object of the present invention is to provide a tilt unit capable of combining two housings in a short time with a simple work content.

SUMMARY OF THE INVENTION The present invention provides a cylindrical shaft having a connecting portion which is inserted into connecting holes of a first housing and a second housing for accommodating a structural body and which is openably and closably connected. In a tilt unit including a body and a tilt spring arranged to be wound around the outer periphery of the cylindrical shaft body and biasing the first casing and the second casing to open. When the connecting portion of the shaft body is inserted into the connecting hole of the second casing, the end face thereof is formed so as to be substantially flush with the surface of the second casing. A cylindrical hole having a predetermined depth is provided in the compression hole, and the compression spring is compressed when the sliding surface is formed at the tip of the compression spring and the end portion of the first casing comes into contact with the compression spring. , A movable member that is pushed out by the compression spring when it matches the connection hole of the first housing is installed internally. Characterized in that was.

[0007]

When the end of the first housing is pushed into the sliding surface of the movable member that is inserted through the connecting hole of the second housing and protrudes from the end surface of the second housing, the component force generated by the angle of the sliding surface is generated. The movable member is moved into the cylindrical hole of the connecting portion. At this time, the compression spring is in a compressed state, and when the first housing moves and the connection hole reaches the position of the movable member, the movable member is pushed out by the compression spring and inserted into the connection hole to insert the first housing. The body and the second housing are connected.

As described above, since the first housing and the second housing can be connected to each other by the support component and the tilt unit that form the hinge and then the second housing can be inverted,
It is possible to eliminate the work while maintaining the positioning state,
Therefore, the work is simplified, and the work man-hour can be significantly reduced.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a cross-sectional view showing the main part of the configuration of the embodiment of the present invention, and FIG. 2 is a perspective view showing the external shape of the embodiment of the present invention.

The embodiment of the present invention has a cylindrical shape having a connecting portion which is inserted into the connecting holes 1a and 2a of the first housing 1 and the second housing 2 for accommodating the structure and which is openably and closably connected. A shaft body 3 and a tilt spring 6 which is arranged in a wound state around the cylindrical shaft body 3 and biases the first housing 1 and the second housing 2 to open. Further, as a feature of the present invention, when the connecting portion of the shaft body 3 is inserted into the connecting hole 2a of the second housing 2, the end face 3a of the end surface 3a is the second housing 2.
A cylindrical hole 3b having a predetermined depth is formed in the shaft core of the shaft body so as to be substantially flush with the surface of the compression spring 4, and the compression spring 4 and the sliding surface 5a at the tip end thereof. A movable member 5 that is formed to compress the compression spring 4 when the end portion 1c of the first housing 1 comes into contact with the movable member 5 and is pushed out by the compression spring 4 when the end portion 1c of the first housing 1 matches the connecting hole 1a of the first housing 1. Will be installed internally.

In assembling the first casing 1 and the second casing 2 using the tilt unit thus constructed, first, the tilt unit and the support are provided in the connecting holes 2a and 2b of the second casing 2. The parts are inserted in advance, and when the first housing 1 is attached, the connecting holes 1b are inserted into the supporting parts already inserted in the second housing 2.

When the first casing 1 is fitted to the second casing 2, the first casing 1 moves in the direction of the arrow as shown in FIG. 3, and its end portion 1c is the second casing. The sliding surface 5a of the movable member 5 protruding from the connecting hole 2a of the body 2 is brought into contact with the sliding surface 5a. When it further moves, a pressing force is applied to the sliding surface 5a of the movable member 5 by the end portion 1c, and the component force pushes the movable member 5 into the cylindrical hole 3b.

As the movable member 5 moves, the compression spring 4 enters a compressed state, and the first casing 1 further moves to move the movable member 5.
When the connection hole 1a reaches the position of, the compression spring 4 expands to insert the movable member 5 into the connection hole 1a of the first housing 1.

By such an operation, the first housing 1 and the second housing 2 are connected by the supporting parts and the tilt unit at the hinge portions A and B shown in FIG. As a result, it is possible to eliminate the work while maintaining the aligned state when turning over the work for screwing the support component and the tilt unit.

[0015]

As described above, according to the present invention, when connecting two casings, it is not necessary to align the connecting holes of the respective casings, and therefore the aligned state can be maintained. However, there is an effect that it is possible to eliminate the work of inverting the two housings, simplify the work content, and reduce the work man-hours.
