Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to an attaching / detaching tool with a handle for attaching / detaching a lid plate to / from an IC tester rack.

[0002]

[Prior art]

 In a conventional IC tester, a fixing screw or the like is used to attach a cover plate that covers the peripheral side of the IC tester rack to the rack. Further, in order to remove the lid plate from the rack, a recess is formed in the lid plate or a handle is provided.

[0003]

[Problems to be solved by the device]

 In a conventional IC tester rack, a concave portion or a handle is formed on the lid plate to remove the lid plate, which impairs the appearance. In addition, if the handle is hidden so as not to damage the appearance, there is a problem that the handle cannot be identified when the lid is removed.

According to the present invention, the movable plate is elastically held in the cover plate, and the movable plate is provided with a knob screw and a handle so that the appearance is improved and the handle is easy to identify. It is intended to provide an attached / detached device.

[0005]

[Means for Solving the Problems]

 In order to achieve this object, the present invention has a movable plate 3 that is elastically contained in a cover plate 2 that covers the peripheral side of an IC tester rack 1 and has one end bent to form a handle portion 3A, and a movable plate 3. And a hole 2A through which the knob portion 4A of the knob screw 4 enters and exits, and a hole 2B through which the knob portion 4A of the knob screw 4 enters and exits are formed in the cover plate 2. When the lid plate 2 is attached to the rack 1 with the knob screws 4, the moving plate 3 moves to the rack 1 side, and the surface of the handle portion 3A and the surface of the knob portion 4A coincide with the surface of the lid plate 2, When the lid plate 2 is detached from the rack 1, the moving plate 3 moves to the lid plate 2 side, and the handle portion 3A and the knob portion 4A project from the lid plate 2.

[0006]

[Action]

 In FIG. 1, the moving plate 3 is covered by the attached plate 5. A connecting plate 6 is attached to the attachment plate 5, and a guide rod 7 is erected on the connecting plate 6. The guide rod 7 has the compression coil spring 8 inserted therein and guides the moving plate 3 in the attached plate 5. The compression coil spring 8 is biased by a force that pushes the moving plate 3 toward the cover plate 2. The knob screw 4 is irremovably held on the moving plate 3 by an E-shaped retaining ring 4C. A handle portion 3A is formed at one end of the moving plate 3. A screw portion 4B is formed at the tip of the knob screw 4, and when the lid plate 2 is mounted on the rack 1 by rotating while pressing the knob portion 4A, the knob portion 4A and the handle portion 3A are buried in the lid plate 2. . When the knob screw 4 is rotated in the direction in which the cover plate 2 is detached, the moving plate 3 is pushed by the compression coil spring 8 and the handle portion 3A projects from the cover plate 2.

[0007]

【Example】

 Next, the structure of the attaching / detaching device for the lid plate according to the present invention will be described with reference to the embodiment of FIG. In FIG. 1, 1 is a rack, 2 is a cover plate, 3 is a moving plate, 4 is a knob screw, 5 is an attached plate, 6 is a connecting plate, 7 is a guide rod, and 8 is a compression coil spring.

In FIG. 1, an attachment plate 5 formed in a convex shape is fixed in the lid plate 2. A connecting plate 6 is attached to the upper part of the outer surface of the attachment plate 5. Two guide rods 7 are erected on the connecting plate 6 so as to project into the attachment plate 5. A compression coil spring 8 is inserted in the guide rod 7.

The moving plate 3 is guided by the guide rod 7 and moves in the attached plate 5. The compression coil spring 8 is biased by a force that presses the moving plate 3 against the cover plate 2. The moving plate 3 has a knob screw 4 rotatably held at a position substantially in the center of the line of intersection of the two guide rods 7. Further, since the knob screw 4 holds the moving plate 3 between the stepped portion of the knob portion 4A and the E-shaped retaining ring 4C, it does not fall off. A threaded portion 4B is formed at the tip of the knob screw 4. The lower end of the moving plate 3 is bent in a U shape to form a handle portion 3A.

The cover plate 2 is formed with a hole 2A through which the handle portion 3A comes in and out and a hole 2B through which the knob portion 4A of the knob screw 4 comes in and out.

Next, the operation of the present invention will be described with reference to FIG. FIG. 2 is a sectional view taken along line AA of FIG. FIG. 2A shows a state in which the cover plate 2 is detached from the rack 1. In FIG. 2A, since the moving plate 3 is pushed toward the cover plate 2 side by the compression coil spring 8, the handle portion 3A projects from the cover plate 2. The lid plate 2 can be easily removed from the rack 1 by holding the handle portion 3A.

When the lid plate 2 is mounted on the rack 1 by rotating while pushing the knob portion 4A from the state of FIG. 2A, the state of FIG. In FIG. 2A, since the moving plate 3 moves to the rack 1 side, and the surfaces of the handle portion 3A and the knob portion 4A coincide with the surface of the lid plate 2, the appearance of the lid plate is improved.

FIG. 3 is an external view of a rack using the attachment / detachment tool according to the present invention. In FIG. 3, two attachments are used on the upper part of the rack 1.

[0014]

[Effect of device]

 In this invention, the movable plate is elastically held in the cover plate, the movable plate is provided with a knob screw and a handle, and when the cover plate is mounted on the rack, the knob and the handle are buried in the cover plate, so the appearance of the rack Will get better. Further, when the lid plate is removed, the handle protrudes from the lid plate, so that the handle can be easily identified.
