BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device such as a large measuring instrument, and more particularly, to a structure of a mounting portion of a handle used for moving the electronic device.

[0002]

2. Description of the Related Art As is well known, in an electronic measuring instrument as shown in FIG. 5, a handle 1A, which can be used as necessary, is provided on an instrument case 2A for convenience in moving to a measuring place. It may be provided on the side surface or the top surface.
That is, FIG. 6 shows such an attachment portion of the handle 1A, and an elongated hole 1b is formed in the attachment end 1a of the handle 1A so that the handle 1A can be pulled out from the side surface of the device case 2A if necessary. However, the mounting end portion 1a is supported by the device case 2A by the nut 5A using a fixing screw 4A for fixing the mounting portion cover 3A to the device case 2A.

That is, a positioning hole 6A into which the positioning projection 3a of the mounting portion cover 3A can be inserted is formed on the surface of the device case 2A, and the mounting portion cover 3A is press-formed.
Is the mounting boss 3b of the mounting portion cover 3A and the mounting end 1
It is attached to the equipment case 2A using the fixing screw 4A and the nut 5A penetrating the long hole 1b.

[0004]

However, according to such a conventional handle handle mounting structure, there is an advantage that the handle handle 1A can be securely mounted to the equipment case 2A, but the head 4a of the fixing screw 4A has a disadvantage. Since it is exposed to the outside, there is a disadvantage that a structure with good appearance cannot be obtained.

Further, in order to solve the above-mentioned appearance problem, a structure as shown in FIGS. 7 and 8 has been conventionally proposed. That is, in this structure, the device case 2B
A mounting hole 7B and a fixing hole 8B are formed on the surface of the handle 1B, and the locking flange 1c integrally formed with the mounting end 1a of the handle 1B is to be locked by the resin mounting cover 3B. Specifically, the mounting portion cover 3B in this structure includes an "L" -shaped hook 3b that can be inserted into the mounting hole 7B and a clip 3c that can be fixed to the fixing hole 8B.
The locking collar 1c of the handle 1B is locked by the pull-out preventing protrusion 3d of the mounting portion cover 3B.

However, according to such a structure,
Since the weight of the electronic device when the handle 1B is used is borne by the resin mounting cover 3B that is mechanically weak and is susceptible to aging, the valuable electronic device is dropped by breaking the mounting cover 3B. Due to the danger, there is a problem that cannot be adopted for a heavy electronic measuring instrument or the like. The object of the present invention is to improve the appearance of the electronic device in view of the above-described problem of the handle handle mounting structure of the conventional electronic device, to have excellent appearance, not to cause aging, and to reduce the weight of the electronic device regardless of the mounting portion cover. An object of the present invention is to provide a handle handle mounting structure for an electronic device that can reliably transmit the handle to a handle.

[0007]

According to the present invention, an object of the present invention is to provide a handle for an electronic device in which a mounting end of a handle is supported on a device case of the electronic device and the mounting end is blinded by a mounting cover. In the handle mounting structure, an insertion hole into which the handle side end of the mounting portion cover can be inserted, a locking hole into which a locking projection at the tip of the handle side end can be inserted, and a latch claw of the mounting portion cover inserted. A lock hole that can be formed in the device case, the mounting end of the handle is supported on the device case by a button screw via a retaining button, and the resin is large enough to surround the mounting end and the retaining button. Insert the handle-side end of the molded mounting portion cover into the insertion hole, move the mounting portion cover with respect to the device case with the latch claw inserted into the lock hole, and lock the locking projection. Fix in the hole It is achieved by the handle the handle attachment structure of the electronic device.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an embodiment of the present invention; FIG. FIG. 1 is an enlarged sectional view corresponding to FIG. 6 of a handle and handle mounting structure of an electronic device according to the present invention.

That is, between the chassis 10 and the device case 2 located inside the device case 2 of the electronic device, a washer interposed between the device case 2 to ensure that the weight of the electronic device can be transmitted to the device case 2. 11, a case fixing screw 12 and a nut 13 are mechanically integrated.

The mounting end 1a of the handle 1 is firmly supported in a screw hole 16 of the washer 11 by using a button screw 15 penetrated by the retaining button 14. That is,
A boss 14a of a retaining button 14 made of metal is inserted into a long hole 1b formed in the mounting end 1a of the handle handle 1. The tip of a button retaining screw 15 passing through the retaining button 14 is Since the screw is screwed into the screw hole 16 of the washer 11, the weight of the electronic device when the handle 1 is used can be reliably transmitted to the handle 1 via the chassis 10, the washer 11 and the button screw 15.

Each of the heads 12a and 15a of the above-mentioned retaining button 14, the mounting end 1a, the case fixing screw 12 and the button fixing screw 15 is formed by a resin molding into a cup shape having an open lower side. Covered by cover 3.
That is, a latch claw 3f that can be engaged with a lock hole 2f of the device case 2 described later is integrally formed at one end of the mounting portion cover 3, and an insertion hole of the device case 2 is formed at the other end of the mounting portion cover 3. An L-shaped handle-side end 3g that can be inserted into 2g (described later) is integrally formed. The handle side end 3g is formed with a handle hole 3h through which the mounting end 1a of the handle handle 1 can be introduced into the inside of the mounting portion cover 3. At the tip of the handle side end 3g, the equipment case 2 is provided. A locking projection 3i that can be engaged with a locking hole 2h (described later) is projected.
