Abstract

A thermometer quick linkage apparatus comprises an elastic member, a button, a probe, and a chamber having one end provided with an opening for receiving the end portion of the probe, and the other end also provided with an opening for receiving the button. Within the chamber, one end of the elastic member connects with the button, and the other end thereof connects with the probe. The elastic member is configured such that, when the button is pressed to compress the elastic member to a certain degree, the end portion of the button comes into contact with the end portion of the probe, and when the button is pressed further down, the probe is pushed away from the chamber. The apparatus is simplified in structure, and allows quick replacement of the probe jacket, and therefore is cost-efficient.

Claims

1. A thermometer quick linkage apparatus, comprising:

an elastic member;

a button having an end provided with an inclined plane;

a probe configured to communicate with a host of the thermometer via a leading wire, the probe having an inclined plane provided at a suitable position on the probe to match with the inclined plane on the button; and

a chamber having a first end provided with an opening for receiving an end portion of the probe, having a second end opposite the first end, and having a side provided with an opening through which a portion of the button is received into an interior of the chamber;

wherein, within the chamber, one end of the elastic member connects with the second end of the chamber, and another end of the elastic member connects with the probe; and

wherein the inclined plane on the button and the inclined plane on the probe are configured such that, when the button is pressed so as to move a greater portion thereof into the interior of the chamber, the inclined plane on the button slides a distance along the inclined plane on the probe so as to push the probe away from the second end of the chamber.

2. The thermometer quick linkage apparatus according to claim 1, wherein the elastic member is a helical spring, one end of which connects with the other end portion of the chamber, and the other end of which is inserted onto the end portion of the probe.

3. The thermometer quick linkage apparatus according to claim 1, wherein a stop member is provided on a portion of the button that is located within the chamber to prevent the button from disengaging from the chamber;

and a stop member is also provided on a portion of the probe that is located within the chamber to prevent the probe from disengaging from the chamber, the stop member defining the position of the elastic member.

4. The thermometer quick linkage apparatus according to claim 1, wherein a neck portion is provided on the opening end of the chamber, protruding outwards for receiving the probe, and is dimensioned to have a probe jacket inserted thereon and to mate snugly with the probe jacket.

5. The thermometer quick linkage apparatus according to claim 1, wherein the elastic member encompasses the end portion of the probe, wherein the end portion of the probe is spaced from an inner wall of the chamber so as not to contact the chamber, and wherein the end portion of the probe remains spaced from the inner wall of the chamber so as not to contact the chamber when the button is pressed.

6. The thermometer quick linkage apparatus according to claim 1, wherein the elastic member and the probe are arranged to be substantially coaxial.
