Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is applicable to electrical products, etc.
The present invention relates to a device having a screw-fastened exterior body in which an exterior cover is screwed to the device body and can be disassembled.

0002

2. Description of the Related Art Generally, equipment that requires disassembly, such as electrical appliances, has an exterior cover fixed to the equipment body with screws, making the exterior cover removable. During disassembly work, the screws removed from the exterior cover were placed casually around the device, or a case was prepared to store the screws and stored there.

However, since the screws removed during disassembly were not placed in fixed locations, the following problems occurred.

(1) Using a similar screw in the wrong position.

(2) Screws are often lost.

(3) Forgetting to install screws.

(4) Even when a case is used to store the removed screws, the case must be prepared for each worker, and since screws of different types and lengths are mixed in the case, it is difficult to store similar screws. It may happen that the screw is used in the wrong position.

[0008]

[Problems to be Solved by the Invention] The problem to be solved by the present invention is that when screwing the exterior case of a removed device back to its original state, the screws may be installed in the wrong position, lost, or incorrectly. There is a problem in installing it.

[0009] An object of the present invention is to provide a device having a screw-fastening type exterior body that allows the screws to be reliably tightened to their original positions when the exterior cover is removed from the device body.

0010

[Means for Solving the Problems] A device having a screw-tightened exterior body that achieves the object of the present invention has a structure in which the back side of the exterior body, which is removably fixed to the device body by screw-fastening, is attached to the device. The present invention is characterized in that a storage portion for storing screws for fixing the exterior body is provided for each screw.

[0011]

[Operation] Since the device having the screw fastening type exterior body configured as described above stores the removed screws one by one in a predetermined storage portion of the exterior body, incorrect installation, loss, or forgetting to attach them is prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 3 are views showing an embodiment of a device having a screw-fastened exterior body according to the present invention.

In the device of this embodiment, as shown in FIG. 2, the top cover 1 is fastened to the main body 12 of the device using screws 14a to 14d, and the bottom cover 13 is fastened to the main body 12 of the device using screws 13a to 13d. Assemble the lower cover 13 first.
After tightening with the lower lid screws 13a to 13d, the upper lid 1 is fastened with the upper lid screws 14a to 14d. Disassembly is performed by removing the upper cover 1 and then removing the lower cover 14. At this time, the top cover 1 that is removed first is placed with its back side facing upward as shown in FIG. 1, and the screws 5 are placed in the storage section 2, which will be described later.

As shown in FIG. 3, on the back side 1a of the top lid 1, a pictorial display section 3 is provided at the center to indicate the positional relationship between the main body 12 of the device, the top lid 1, and the bottom lid 13, and the mounting positions of screws. A screw storage section 2 partitioned by a frame is formed around it in correspondence with the mounting position of each screw, and these screw storage sections 2 correspond one-to-one to the number of screws used for assembly. Further, the picture display section 3 displays the types of screws, such as countersunk screws M3×5 and pan head screws M3×4, corresponding to each storage section 2. 4 indicates a screw hole into which a screw is inserted.

As described above, when disassembling the device of this embodiment, the screws 14a to 14d for the top cover are placed in the corresponding storage areas 2 formed on the back side of the top cover 1 that is first removed. Then, remove the screws 13a to 13 of the lower cover 13.
d is placed in a predetermined storage part of the upper lid 1. Therefore, it is possible to prevent screws from being lost and to prevent them from being installed in the wrong position during assembly. Furthermore, since the types of screws are displayed, even if you accidentally lose a screw during assembly, you can easily determine what type of screw to use.

FIG. 4 is a perspective view showing another embodiment of the device according to the invention.

In the above-described embodiment, the storage section for storing the removed screws is partitioned into a frame shape, but in this embodiment, the storage section 22 is partitioned into a hole section 22 as shown in FIG.
It can be stored in a predetermined position by forming the screw into a protrusion shape having a shape of 1.a and placing the removed screw in the hole 22a of the corresponding storage part 22 so as to be inserted thereinto.

According to this embodiment, since the screw is stored with its head always facing upward, the screw can be easily taken out from the storage portion by using, for example, a magnetized screwdriver. , work efficiency is improved.

[0019]

[Effects of the Invention] As explained above, according to the present invention,
The following effects can be obtained.

(1) Since there is a storage part for screws, workability during assembly is good and loss of screws can be prevented.

(2) Since the number of screw storage portions corresponds one-to-one with the number of screws, there is no chance of installing a screw in the wrong position or forgetting to install a screw.

(3) Even if you accidentally lose a screw during assembly,
You can easily determine the type of screw to use immediately.

(4) There is no need to separately prepare a dedicated case to store the screws.
