Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to an electronic thermometer suitable for use as a women's thermometer or the like.

(Summary of the Invention) This electronic thermometer is used for women's thermometers, etc., and the thermometer body is also used as a cord reel, so that the case can be made smaller and the structure more compact.

(Background of the invention).

Since women's thermometers and the like are used to measure temperature by looking at the display section of the thermometer body while holding the temperature probe under the tongue, it is necessary to provide a relatively long connection cord on the thermometer body. Since this cord is a nuisance when measurements are not being taken, the inventors of the present invention previously proposed a thermometer body with a reel for winding the cord.

However, when the cord reel is assembled to the thermometer body, the base end of the cord and the thermometer body must be connected by a mechanical contact, such as a contact brush, and this mechanical contact portion There was an electrical loss, which could reduce measurement accuracy. In addition, when incorporating the cord reel into the thermometer body, since the cord reel occupies most of the inside of the case, it is necessary to secure space for storing the circuit section of the thermometer body, which inevitably requires the case. It was also pointed out that the disadvantage was that it became larger.

Furthermore, since the cord reel rotates in both directions, if the cord is wound in the wrong direction, the end of the cord pulled out from the reel will be wound up in a bent state, which may cause the cord to break.

(Purpose of the Invention) The present invention provides an electronic thermometer with a cord reel function, in which the thermometer body and the connection cord can be directly connected by soldering, etc., the case can be made smaller, and the cord reel is prohibited from reversing. The purpose is to add functionality and prevent cord breakage.

(Configuration and Effects of the Invention) In order to achieve the above object, the present invention includes a case, a cord that is retractably housed in the case, a temperature measuring probe provided at the tip of the cord, and a display surface that is visible through the case. The body of the thermometer is rotatably held in the case with the base end of the cord pulled out along the normal direction on the outer periphery, and the body of the thermometer also serves as a cord reel. and a stopper for preventing reversal located between the two parts.

With the above configuration, the present invention enables direct connection between the cord and the case by soldering or the like without relying on mechanical connection, and improves measurement accuracy and reliability. This also reduces the number of parts,
Cost reduction can be achieved.

Furthermore, since the case itself can be made smaller, marketability is improved. In other words, in addition to being practical as a measuring instrument, this type of women's thermometer is also required to be small and lightweight, easy to carry, and have a certain fashion sense. can be fully satisfied and the product quality can be improved.

Furthermore, in this invention, if an attempt is made to wind the cord in the opposite direction, the cord hits the stopper and cannot be wound, so the base end of the cord is always wound along the outer periphery from the normal direction of the thermometer body. The cord will not be bent, disconnected, or disconnected from the thermometer's internal circuit.

(Description of Embodiments) FIG. 1 is an exploded perspective view of a female thermometer according to the present invention, and FIG.
The figure is a perspective view of the assembled state.

In the figure, this women's thermometer consists of an upper case 1 and a lower case 2, which constitute a flat box-shaped case, and an upper and lower case 1.
2, a connecting cord 4 wound around the outer periphery of the thermometer body 3, and a temperature measuring probe 5 attached to the tip of the connecting cord 4 bent in an L-shape.

The upper and lower cases 1.2 have a thin square shape, and openings 1a and 2a are formed in the center to expose the upper and lower surfaces of the thermometer body 3.

Further, the upper and lower cases 1.2 are assembled by fitting three locking claws 6 erected on the edges of the lower case 2 into the upper case 1 side and joining them together with screws 7.

The thermometer main body 3 has a thin disc shape, and is rotatably held within the upper and lower cases 1.2 by abutting the inner peripheral portions of the openings 1a and 2a with seven flanges 3a formed on its upper and lower peripheral edges. be done.

Further, a plurality of guide plates 8 are formed inside the upper and lower cases 1.2 to abut against the peripheral edges of the seven flange 3a to smooth the rotation.

The base of the cord 4 is directly fixed inside the thermometer body 3 and drawn out from the outer periphery of the thermometer body 3, and is directly connected to the internal circuit of the thermometer body 3 by soldering or the like.

A display section 3b and a switch 3C are arranged on the front side of the thermometer main body 3. Further, on the back side, as shown in FIG. 3, an operating groove 3d for rotational operation and a mounting hole 3e into which a battery is installed are formed.
A lid 3f is arranged at e. Furthermore, an arrow 3q is formed on the back surface to indicate the winding direction of the cord 4.

The cord 4 is pulled out from a cord pulling notch 2b (the upper case 1 side is omitted) that is opened on one side of the upper and lower cases 1 and 2. A probe holding part 9 in which the temperature measuring probe 5 is housed is integrally formed on the sides of the upper and lower cases to protrude, and a pair of U-shaped locking parts 10 are formed within this probe holding part 9. A locking projection 10a is integrally provided at the tip of the locking portion 10, and as shown in FIG. 4, when the probe 5 is housed in the probe holding portion 9, the outer circumference of the probe 5 is locked. The probe 5 is held on the locking portion 10 by climbing over the stop projection 10a.

Therefore, in order to remove the probes 0-15 from the state in which they are held in the holding portion 9, the probes 5 are pulled out by placing a finger over the locking protrusion 10a and pulled out to the outside.

Then, if you pull out the cord 4 from the case, the thermometer body 3
It is pulled out to a predetermined length while rotating.

In addition, in order to store the cord 4 in the case from the drawn state, place your finger in the groove 3d provided on the back side and turn the thermometer body 3 in the direction of the arrow 39, and the cord 4 will be wound up.
It is stored inside the case.

In the completely retracted state, the temperature measuring probe 5 is in a position almost parallel to the probe holding part 9, so by pressing the probe 5 with your fingertip in this state, the outer periphery of the probe 5 will go over the locking protrusion 10a and engage the locking claw. It will be kept within 10.

Next, the configuration of the lead-out end of the cord 4 from the thermometer body 3 will be explained using FIG. 5.

In the figure, a stepped portion 30 with a part of the outer periphery cut out is formed at the pull-out position of the cord 4 of the thermometer body 3, and a grommet 41 constituting the base end of the cord 4 is formed in this notched stepped portion 30.
is attached along the normal direction of the thermometer body 3, and the cord 4 is further inserted into the grommet 41.

A stopper 12 for preventing reverse rotation is provided protruding from the inner bottom of the lower case 2 between the outer periphery of the flange portion 3a and the cord 4 near the notch 2b.

Although not shown, the same stopper is also provided protruding inside the upper case 1 side, and by bringing the upper and lower cases 1.2 together, both stoppers are brought into contact with each other.

As shown in the figure, the stopper 12 comes into contact with the tip of the grommet 41 when the cord 4 is pulled out to the maximum extent from the case, thereby stopping the cord 4 from being pulled out without applying any extra tension.

To wind the cord 4 from this state, wind it in the direction of the arrow [A], that is, in the direction indicated by the display arrow 3Q.
The cord 4 is wound along the outer periphery of the thermometer body from the normal line, so that the cord 4 is not forcibly bent and wound.

Further, if the winding direction is to be reversed as indicated by the arrow, the tip of the grommet 41 will come into contact with the stopper 12, and the reverse rotation will be prevented.

Furthermore, even if the cord 4 is in contact with the stopper 12 and the cord 4 is in contact with the stopper 12, the gap between the outer periphery of the thermometer body 3 and the stopper 12 is small, so even if the cord 4 is flexible, the cord 4 will fall into this gap. It never goes inside. therefore,
Even if an attempt is made to wind the cord 4 in the opposite direction while the cord 4 is being pulled out, the cord 4 cannot be wound, and can only be wound in the indicated direction.
