Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a tool holding structure.

[Prior Art] Conventionally, when performing maintenance, adjustment, parts replacement, etc. of electronic devices,
In each case, bring out the tool box from the storage and select the necessary tool, and after finishing the work, keep the tool, and the work of storing in the storage is troublesome and troublesome, so for some electronic devices, etc., We have tools that are frequently used,
I try to speed up the work. FIG. 5 is a conventional example showing such a tool holding structure, 1 is an opening / closing door for closing the opening of the apparatus housing, 2 is a tool holding member, and the tool holding member 2 is made of a metal plate, a resin material or the like. By being formed in a U shape in a side view, it is composed of a pair of horizontal bent portions 3a and 3b facing each other up and down, and a connecting portion 3c connecting the rear ends of the pair of bent portions 3a and 3b, Tool holding holes 5a, 5b into which the tool 4 is inserted from above are provided at the central portions of the respective bent portions 3a, 3b, and the connecting portion 3c is fixed to an appropriate position on the inner surface of the opening / closing door 1 by a set screw or the like.

The tool 4 is composed of a precision screwdriver or the like, and has, for example, a hexagonal head 4a, a large diameter portion 4b, a taper portion 4c and a small diameter portion 4d, and the large diameter portion 4b is a bent portion 3a on the upper side. Holding hole 5a
Further, the small diameter portion 4d is inserted and held in the tool holding hole 5b of the lower bent portion 3b.

The tool holding hole 5a is smaller than the outer diameter of the head 4a and has a large diameter portion.
The tool holding hole 5b has a hole diameter larger than the outer diameter of the large diameter portion 4b, and the tool holding hole 5b has a hole diameter smaller than the outer diameter of the large diameter portion 4b and larger than the outer diameter of the small diameter portion 4d. To prevent.

[Problems to be solved by the invention] However, in such a conventional tool holding structure, since the tool 4 can move within the tool holding holes 5a and 5b, rattling due to external vibration or the like and the cause of noise generation In addition, there is a problem in that if the device is tilted by a certain angle or inverted, the device may be easily dropped from the tool holding holes 5a and 5b and may be lost.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and its purpose is to prevent the tool from vibrating and falling off with a relatively simple structure, and securely hold and fix the tool. It is to provide a holding structure for a tool that is designed to be obtained.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a tool holding member having a tool holding hole into which a tool having an upper end portion protruding from a main body portion is inserted from above, and a tool holding member of the tool holding member. An elastic member located above and provided with a protrusion protruding from the tool mounting surface is disposed on the tool mounting surface, and the elastic member is constantly pressed against the upper end of the tool held by the tool holding member, The movement is prevented, and the housing provided with the tool holding member is prevented from tilting and falling off due to vibration or the like.

[Operation] In the present invention, the elastic member is compressed and deformed by the upper end portion of the tool, and the elastic force presses the tool so that it does not move.

[Embodiment] Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings.

FIG. 1 is a perspective view showing an embodiment of a tool holding structure according to the present invention, and FIG. 2 is a side sectional view of the structure. The fifth
The same parts as those of the conventional structure shown in the figure are designated by the same reference numerals. In these drawings, reference numeral 10 denotes a device housing such as an electronic device. A tool holding member 2 is provided at an appropriate position on an inner surface of an opening / closing door 1 which is openably and closably attached to a rear opening 11 of the device housing 10. 2 and an elastic member 12 located above the elastic member 12, which holds and fixes the tool 4.

Since the tool holding member 2 and the tool 4 are exactly the same as the conventional ones shown in FIG. 5, their explanations are omitted.

The elastic member 12 is formed of rubber, sponge, or the like into a rectangular block shape having an appropriate plate thickness, and has a projection portion protruding forward from the upper end portion of the front surface thereof and located above the tool holding hole 5a of the tool holding member 2. 13 are projected integrally. protrusion
The upper surface 13a of the member 13 is horizontal, the lower surface 13b is inclined rearward and downward, and the inclined surface intersects the front surface 12a of the elastic member 12 at an obtuse angle. And the elastic member
The front surface 12a of 12 is positioned in front of the rear surface of the head 4a of the tool 4 held by the tool holding member 2 by an appropriate dimension (eg, about 1 to 2 mm). Therefore, when the tool 4 is inserted into the tool holding holes 5a, 5b of the tool holding member 2, its head 4a
As shown in Fig. 2, a part of the tool is buried in the lower part of the front surface of the elastic member 12, and this prevents rattling of the tool 4 in the vertical and horizontal directions.

When inserting the tool 4 into the tool holding holes 5a and 5b, as shown in FIG. 3, the tool 4 is tilted forward at an appropriate angle and the lower end small diameter portion 4d is first inserted into the tool holding hole 5a from an obliquely upper position. When the head 4a is below the protrusion 13 of the elastic member 12 by inserting a certain amount of the diameter portion 4b, the head 4a is pressed against the upper front surface of the elastic member 12 in the substantially vertical state shown in FIG. Press down with the small diameter part 4d into the tool holding hole 5b
It is sufficient to insert it until 4c contacts the peripheral edge of the hole.

In this case, the protrusion 13 is located above the head 4a, so that even if the tool 4 comes out of the tool holding hole 5b, the tool holding member 2
Serves as a stopper to prevent the product from falling off.

When pulling out the tool 4 from the tool holding holes 5a and 5b, pull up the tool 4 right above to pull out the small-diameter portion 4d from the tool holding hole or 5b as opposed to the time of mounting, and then tilt forward to tilt the head 4a. protrusion
It may be located in front of 13, and in this state, pulled up in the axial direction and pulled out from the tool holding hole 5a.

Although the tool mounting surface is the inner side surface of the opening / closing door 1 in the above-described embodiment, the present invention is not limited to this and may be the inner wall surface of the device housing 10.

[Advantage of the Invention] As described above, the tool holding structure according to the present invention includes a tool holding member having a tool holding hole into which the tool is inserted,
Since it is composed of an elastic member that is located above the tool holding member and the upper end of the tool is pressed against it, it will not rattle due to vibration etc., and will not fall out of the tool holding hole even if the device is tilted or inverted. The tool can be stably and surely held and fixed, and the structure is simple, and the conventional structure can be improved simply by adding an elastic member.
