Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glass thermometers, especially a mercury-free glass thermometer. Background Art
[0002] A mercury-free glass thermometer is a temperature measuring instrument without mercury element. It uses a gallium-based liquid alloy as the temperature-sensing material, replacing the mercury in traditional mercury thermometers. This design not only retains the high-precision measurement ability of mercury thermometers (the error range is usually within ±0.15°C), but also eliminates the environmental pollution and health risks of mercury. Mercury-free glass thermometers usually have utility model patents and belong to class II medical devices. They are suitable for measuring body temperature in areas such as the mouth, armpit, or anus. Due to their non-toxic, harmless, and non-radiating characteristics, mercury-free glass thermometers meet international medical device standards and are environmentally friendly products.
[0003] Existing mercury-free glass thermometers are placed inside a protective shell when not in use, and the protective shell is used to protect them. However, there is no limit on the mercury-free glass thermometer. During the carrying process, the mercury-free glass thermometer can shake inside the protective shell, and the shaking causes the mercury-free glass thermometer to collide with the inner wall of the protective shell, which is likely to cause damage to the mercury-free glass thermometer. Content of the Utility Model
[0004] To solve the above technical problems, the utility model provides a mercury-free glass thermometer.
[0005] The utility model is realized by the following technical solutions: A mercury-free glass thermometer, including a protective outer shell, a protective cover is snap-connected to the right end of the protective outer shell, a pull ring is fixedly connected to the right end of the protective cover, a glass thermometer body is arranged inside the protective outer shell, a limiting spring is fixedly connected to the inner wall of the protective outer shell, one end of the limiting spring is fixedly connected to an inclined surface limiting plate, a protective pad is fixedly connected to the inner wall of the protective outer shell, and a sponge block is fixedly connected to the inner wall of the protective cover.
[0006] Through the above technical solutions, pulling the pull ring will drive the protective cover to move, so that the protective cover can be removed, and then the glass thermometer body inside the protective outer shell can be removed. The operation is convenient. The inclined surface structure of the inclined surface limiting plate causes the inclined surface limiting plate to move, compressing the limiting spring, allowing the measuring head of the glass thermometer body to enter the round hole, and then the elastic action of the limiting spring fixes the thermometer body to prevent the glass thermometer body from moving.
[0007] As a further improvement of the above solution, the number of the limiting springs is set to four, and the four limiting springs are symmetrically distributed with the protective outer shell as the center. The inner wall of the inclined surface limiting plate is in contact with the surface of the glass thermometer body.
[0008] Through the above technical solution, four limiting springs are used to increase the clamping force of the inclined surface limiting plate on the glass thermometer body.
[0009] As a further improvement of the above solution, the number of the inclined surface limiting plates is set to two, and the two inclined surface limiting plates are symmetrically distributed with the protective shell as the center.
[0010] As a further improvement of the above solution, circular holes are formed in the inner wall of the protective pad, and the left end of the glass thermometer body extends into the interior of the circular holes.
[0011] As a further improvement of the above solution, a fixing block is fixedly connected to the inner wall of the protective shell, and a rubber protective pad is fixedly connected to the inner wall of the fixing block.
[0012] Through the above technical solution, the surface of the glass thermometer body is protected by the rubber protective pad to prevent the glass thermometer body from being damaged by collision.
[0013] As a further improvement of the above solution, the fixing block is located at the right end of the inclined surface limiting plate, and the rubber protective pad is located outside the glass thermometer body.
[0014] As a further improvement of the above solution, a groove is formed in the inner wall of the sponge block, and the right end of the glass thermometer body extends into the interior of the groove.
[0015] Through the above technical solution, the sponge block inside the protective cover provides additional protection for the right end of the glass thermometer body, increasing the safety during storage.
[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0017] In the present utility model, by setting the limiting spring, the inclined surface limiting plate, the protective pad and the rubber protective pad, specifically, the glass thermometer body is passed through the rubber pad and then pushed into the protective shell. When the left end of the glass thermometer body contacts the inclined surface limiting plate, since the inner wall of the inclined surface limiting plate is inclined, the inclined surface limiting plates are pushed to move away from each other, compressing the limiting spring, so that the left end of the glass thermometer body enters the interior of the circular hole, thereby realizing the protection of the measuring head at the left end of the glass thermometer body. The glass thermometer body is clamped and fixed by the elastic force of the limiting spring in cooperation with the inclined surface limiting plate, and the glass thermometer body is limited by the rubber protective pad to prevent the glass thermometer body from shaking during carrying, thereby avoiding the glass thermometer body from being damaged by collision and extending the service life of the glass thermometer body.
[0018] The utility model provides protection for the right end of a glass thermometer body through a sponge block. Specifically, a protective cover is snap-fitted onto the surface of a protective housing, and the sponge block inside the protective cover safeguards the right end of the glass thermometer body. Meanwhile, a groove positions the glass thermometer body, enhancing the protection effect for the glass thermometer body. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Embodiment:
[0028] Please refer to Figures 1-5, the mercury-free glass thermometer of this embodiment includes a protective housing 1. A protective cover 2 is clamped at the right end of the protective housing 1. A pull ring 3 is fixedly connected to the right end of the protective cover 2. A glass thermometer body 4 is arranged inside the protective housing 1. A limiting spring 5 is fixedly connected to the inner wall of the protective housing 1. One end of the limiting spring 5 is fixedly connected to an inclined surface limiting plate 6. A protective pad 7 is fixedly connected to the inner wall of the protective housing 1. A sponge block 11 is fixedly connected to the inner wall of the protective cover 2. Push the glass thermometer body 4 through the rubber pad 10 and then into the protective housing 1. When the left end of the glass thermometer body 4 contacts the inclined surface limiting plate 6, since the inner wall of the inclined surface limiting plate 6 is an inclined surface, it will push the inclined surface limiting plates 6 to move away from each other, compressing the limiting spring 5, so that the left end of the glass thermometer body 4 enters the inside of the round hole 8, thus realizing the protection of the measuring head at the left end of the glass thermometer body 4. The glass thermometer body 4 is clamped and fixed by the elastic cooperation of the limiting spring 5 and the inclined surface limiting plate 6 to prevent the glass thermometer body 4 from shaking during carrying.
[0029] The number of the limiting springs 5 is set to four, and the four limiting springs 5 are symmetrically distributed with the protective housing 1 as the center. The inner wall of the inclined surface limiting plate 6 contacts the surface of the glass thermometer body 4.
[0030] The number of the inclined surface limiting plates 6 is set to two, and the two inclined surface limiting plates 6 are symmetrically distributed with the protective housing 1 as the center.
[0031] A round hole 8 is opened in the inner wall of the protective pad 7, and the left end of the glass thermometer body 4 extends into the inside of the round hole 8.
[0032] A fixing block 9 is fixedly connected to the inner wall of the protective housing 1, and a rubber protective pad 10 is fixedly connected to the inner wall of the fixing block 9.
[0033] The fixing block 9 is located at the right end of the inclined surface limiting plate 6, and the rubber protective pad 10 is located outside the glass thermometer body 4. The glass thermometer body 4 is limited by the rubber protective pad 10 to prevent the glass thermometer body 4 from shaking during carrying.
[0034] A groove 12 is opened in the inner wall of the sponge block 11, and the right end of the glass thermometer body 4 extends into the inside of the groove 12. Clamp the protective cover 2 on the surface of the protective housing 1. The right end of the glass thermometer body 4 is protected by the sponge block 11 inside the protective cover 2, improving the protection effect on the glass thermometer body 4.
[0035] The implementation principle of the mercury-free glass thermometer in the embodiments of this application is as follows: When in use, pulling the pull ring 3 will drive the protective cover 2 to move, so as to remove the protective cover 2, and then the glass thermometer body 4 inside the protective housing 1 can be removed. When storage is needed, the glass thermometer body 4 is passed through the rubber pad 10 and then pushed into the interior of the protective housing 1. When the left end of the glass thermometer body 4 contacts the inclined surface limiting plate 6, since the inner wall of the inclined surface limiting plate 6 is inclined, the inclined surface limiting plate 6 is pushed to move away from each other, compressing the limiting spring 5, so that the left end of the glass thermometer body 4 enters the interior of the circular hole 8, thereby realizing the protection of the measuring head at the left end of the glass thermometer body 4. The glass thermometer body 4 is clamped and fixed by the elastic cooperation of the limiting spring 5 and the inclined surface limiting plate 6, and the glass thermometer body 4 is limited by the rubber protection pad 10 to prevent the glass thermometer body 4 from shaking during carrying, thus avoiding the collision and damage of the glass thermometer body 4 and prolonging the service life of the glass thermometer body 4.
