Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lock knob fixing structure, and more particularly to a lock knob fixing structure used for a battery lock portion of a mobile phone or the like.

[Conventional technology]

2. Description of the Related Art Conventionally, as a lock knob fixing structure used for a battery lock part of a mobile phone, as shown in FIG. 2, there are grooves 22 on both sides of the back surface of the lock knob 21, and a spring 23 is put in this groove 22 to make a housing. One that is slidably held by sandwiching 24 and slides in the vertical direction. Also, as shown in FIG. 3, the lock knob 31 has a through hole 32 having two steps, and a spring 33 is provided in this through hole 32. There has been a device that locks a battery or the like placed in the housing by inserting the lock knob 31 and sliding the lock knob 31 in the vertical direction.

[Problems to be solved by the device]

In the example of FIG. 2, the conventional lock knob fixing structure described above holds the spring between the lock knob and the housing only by the spring pressure. Problems such as loss of slide operation function occur. Further, in the example of FIG. 3, the lock knob and the housing need to have a certain size in order to provide the rail portion for sliding operation, and the lock knob needs to be provided with two through holes. There is a drawback that the shape etc. becomes complicated.

[Means for Solving the Problems]

The lock knob fixing structure of the present invention includes a housing for mounting batteries on one surface, and a lock for locking the batteries provided on an end surface perpendicular to the surface slidably in a direction parallel to the end surface. A knob, a spring housed in a groove provided in the lock knob to apply a biasing force to the lock knob, a metal fitting to which the lock knob is slidably attached to the end surface, and the end surface of the housing In the area where the spring is located, and a recess for holding and guiding the spring.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

FIG. 1 (a) is an exploded perspective view of an embodiment of the present invention, and FIGS. 1 (b) and (c) are a side view and a rear view of a lock knob in this embodiment.

In this embodiment, a housing 14 for mounting batteries on one surface is provided.
A lock knob 11 that is slidably provided in a direction parallel to the end surface perpendicular to the surface of the housing 14 to lock the batteries, and a lock knob 11 that is housed in a groove 12 provided in the lock knob 11 Spring 15 that gives bias to
A metal fitting 16 for mounting the lock knob 11 with a screw 17 so as to be slidable on the end surface of the housing 14, and a spring provided on the end surface of the housing 14 where the spring 15 is located.
And a recess 13 for holding and guiding 15.

That is, as shown in FIG. 1, in this embodiment, grooves 12 are formed on both sides of the back surface.
The spring 15 is sandwiched between the lock knob 11 provided with the above and the casing 14 having the recess 13 for fixing the spring so as to fit in the grooves 12 on both sides of the rear surface, and the lock knob 11 is slid from the front side through the metal fitting 16 with the screw 17. Screw it so that it can move. This time,
The spring 15 has a structure in which it is sandwiched between grooves 12 on both sides of the back surface of the lock knob 11 and a housing 14, and is held and guided by a recess 13 provided in the housing 14.

According to this embodiment having such a structure, even if the lock knob 11 slides in the vertical direction to lock the batteries placed on the housing 14, the buckling of the spring 15 due to an impact or the like does not occur. A stable lock operation can be performed without generating.

[Effect of device]

As described above, the present invention has a structure in which the spring is sandwiched between the groove on the back surface of the lock knob and the housing, and the spring end portion is inserted into the recessed portion provided in the housing to guide the spring retention. Due to such reasons, the spring does not buckle and come off, and the lock knob itself can be made small, resulting in a great practical effect.
