Description

Technical Field

[0001] The utility model relates to the technical field of thermometers, in particular to a thermometer with a shielding structure. Background Art

[0002] Thermometer is also called "medical thermometer". The working substance of the thermometer is mercury. The volume of its glass bulb is much larger than that of the capillary tube. The mercury in the bulb undergoes a slight change due to the influence of body temperature. The expansion of the mercury volume causes a significant change in the length of the mercury column in the tube, so the body temperature can be read by checking the reading indicated by the mercury.

[0003] However, the mercury thermometers in the existing thermometers are mostly stored inside the plastic shell because the glass bulb container and the glass tube container are easily damaged and broken. They are taken out when used. During the process of measuring the body temperature after being taken out, they are not provided with a protective structure, which makes them easily damaged when bumped. Utility Model Content

[0004] The purpose of the utility model is to provide a thermometer with a shielding structure to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a thermometer with a shielding structure, comprising a mercury thermometer, an outer cylinder body is sleeved on the outer wall of the mercury thermometer, an annular groove is provided on the outer cylinder wall at the bottom of the outer cylinder body, an inner top and an inner bottom of the annular groove are provided with external thread grooves, a rotating sleeve is movably sleeved on the outer wall of the bottom of the outer cylinder body, a sleeve ring is fixedly connected to the inner top of the rotating sleeve, an inner wall of the inner circle side of the sleeve ring is provided with an internal thread groove, and the internal thread groove is adaptively arranged with the external thread groove.

[0006] Preferably, a first holding groove is formed on the outer wall of the outer cylinder above the annular groove.

[0007] Preferably, a plurality of second holding grooves are provided at equal intervals on the outer wall of the rotating sleeve.

[0008] Preferably, a viewing slot is provided through the outer wall of the outer cylinder.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the utility model is a thermometer with a shielding structure, which has a simple structure and is easy to use. A rubber outer cylinder is sleeved on the mercury thermometer, and a through viewing groove is provided on the outer cylinder, so that it does not affect the reading of the thermometer, and a freely retractable rotating sleeve is sleeved on the bottom of the outer cylinder. The rotating sleeve can be tightened and limited with the outer thread groove on the inner wall of the ring groove through the internal thread groove on the inner wall of the sleeve ring. The rotating sleeve and the outer cylinder can respectively protect the glass bulb container and the glass tube container in the mercury thermometer. Even if the thermometer is in use, the outer cylinder can still protect it, which can effectively make the thermometer have a certain anti-fall performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-5The utility model provides a technical solution: a thermometer with a shielding structure, including a mercury thermometer 3, an outer cylinder 1 is sleeved on the outer wall of the mercury thermometer 3, an annular groove 12 is provided on the outer cylinder wall at the bottom of the outer cylinder 1, and an outer thread groove 14 is provided at the inner top and inner bottom of the annular groove 12, a rotating sleeve 2 is movably sleeved on the outer wall at the bottom of the outer cylinder 1, a sleeve ring 22 is fixedly connected to the inner top of the rotating sleeve 2, an inner thread groove 23 is provided on the inner wall of the inner circle side of the sleeve ring 22, and the inner thread groove 23 is adapted to the outer thread groove 14.

[0018] A first holding groove 11 is provided on the outer wall of the outer cylinder 1 above the annular groove 12. The first holding groove 11 makes the thermometer more comfortable and stable when being held.
