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.

(I main point 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 can be made more compact.

(Background of the Invention) Women's thermometers and the like are designed to measure temperature by looking at the display on the thermometer body with the temperature measuring probe under the tongue, so they require a relatively long connection cord to be connected to the thermometer body. It is necessary to provide 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, space must also be secured to accommodate the circuit section of the thermometer body, which inevitably results in The drawback of the larger case was also pointed out.

(Objective of the Invention) The present invention provides an electronic thermometer with a cord reel function that allows the thermometer main body and the connection cord to be directly connected by soldering, etc., and that the case can be made smaller and that the display is easier to see during use. , the purpose is to improve operability.

(Structure and Effects of the Invention) In order to achieve the above object, the present invention includes a case, a cord that can be pulled out at the bottom of the case, a temperature measuring probe provided at the tip of the cord, and a display surface on the front of the case. It consists of a thermometer body that is rotatably held in a case in a visible state and also serves as a cord reel, with the base end of the cord pulled out from the outer periphery, and the base end of the cord is held in the normal direction of the thermometer body. At the same time, when the display surface of the thermometer body is rotated to the front position that matches the front of the case, it touches the base of the cord between the cord and the outer periphery of the thermometer body, and the rotation of the thermometer body The case is characterized by a stopper that stops the movement.

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, the display surface of the thermometer main body is located at a front position that coincides with the front of the case when the cord is pulled out to the maximum, so that the display is easy to see and the switch is easy to operate.

(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.
A thermometer body 3 is held between the thermometer body 3, a connection cord 4 wound around the outer periphery of the thermometer body 3, and a temperature measuring probe 5 attached to the tip of the connection cord 4 bent in an abbreviated 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 for indicating the direction in which the cord 4 is wound is formed on the back surface.

The cord 4 is pulled out from a cord pull-out notch 2b (the upper case 1 side is omitted) opened at one side of the lower part of the upper and lower cases 1.2. A probe holding part 9 in which a temperature measuring probe 5 is housed is integrally formed on the lower side of the upper and lower cases 1.2 on the drawer end side, and a pair of U-shaped locking parts are formed inside this probe holding part 9. Part 10
is formed. A locking protrusion 10 is provided at the tip of the locking portion 10.
a is integrally protruded, and as shown in FIG.
-15 is housed in the probe holding part 9, the outer periphery of the probe 5 climbs over the locking protrusion 10a and the locking part 10
The probe 5 is held in place.

Therefore, in order to remove the probe 5 from the state in which it is held in the holding portion 9, the probe 5 is pulled out by placing a finger on the holding portion 9, and the probe 5 is pulled out over the locking protrusion 10a.

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 3Q, and the cord 4 will be wound up.
It is stored inside the case.

In the fully retracted state, the temperature measuring probe 5 is in a position almost parallel to the probe holding part 9, so in this state, the temperature measuring probe 5 is
By pressing 15 with a fingertip, the outer periphery of the bulb 5 passes over the locking protrusion 10a and is held within the locking pawl 10.

The above operations are most convenient to use when the case is viewed from the front and held with one hand, with the holding part 9 positioned at the bottom. When the thermometer main body 3 is at its rotation stop position with the cord 4 pulled out, the display section 3b coincides with the front of the case and assumes the front position. This structure will be further explained using FIG. 5.

In the figure, a stepped portion 30 with a part of the outer periphery cut out is formed at the pulled-out position of the hood 4 of the thermometer main 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.

In the vicinity of the notch 2b, a stopper 12 for the pull-out position 1111 is provided between the outer periphery of the 7 flange portion 3a and the cord 4.
protrudes from the inner bottom of the lower case 2.

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 shoulder 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.

In other words, the contact position between the grommet 41 and the stopper 12 is the rotation stop position of the thermometer main body 3, so at this rotation stop position, the front position of the display part 3b is adjusted to the case as shown in FIGS. 3 and 5. By matching the front position, the display can be made easier to see.

The stopper 12 also has a reverse rotation prevention function.

In other words, to wind up the cord 4 from the maximum pull-out position, wind it in the direction of the arrow [A], that is, if you wind it in the direction indicated by the display arrow 39, the cord 4 will be wound up from the point 11L along the outer periphery of the thermometer body. This prevents the cord 4 from being forcibly bent and wound up.

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 up, and can only be wound in the indicated direction, thereby preventing wire breakage due to forcibly winding the cord 4 in the opposite direction.
