Description

Technical Field

[0001] This utility model relates to the field of thermometer technology, specifically a thermometer scale magnification detection device. Background Technology

[0002] A thermometer is a tool that can accurately determine and measure temperature. It is divided into pointer thermometers and digital thermometers. Various types of thermometers have been designed and manufactured according to their different uses. The thermometers utilize the phenomenon that solids, liquids, and gases expand and contract with temperature. Under constant volume conditions, the pressure of a gas (or vapor) changes with temperature. The thermoelectric effect plays a role. Resistance changes with temperature. The effect of thermal radiation, etc.

[0003] Chinese utility model patent CN201828350U, published on May 11, 2011, discloses a thermometer integrating a sliding magnifying glass. The thermometer has a cylindrical glass tube and a temperature measuring medium inside the glass tube. The glass tube has a scale. The key feature is that a transparent sliding ring is fitted onto the glass tube and can slide along the glass tube. A magnifying glass for observing the scale is embedded in the transparent sliding ring. The thermometer of this utility model, which integrates a sliding magnifying glass, allows the transparent sliding ring to be slid to the desired position when a reading is needed, so that the scale can be clearly seen with the help of the magnifying glass, which is very convenient.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing thermometer scale magnification structure is designed to magnify the scale lines and values ​​at the measurement position when measuring body temperature. It cannot quickly detect whether all the scales on the thermometer are qualified, cannot meet the quality inspection requirements before the thermometer leaves the factory, and cannot quickly detect all the scale lines and values ​​on the thermometer. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that the existing thermometer scale magnification structure is designed to magnify the scale lines and values ​​at the measurement position when measuring body temperature, but cannot quickly detect whether all the scale lines on the thermometer are qualified, thus failing to meet the quality inspection requirements before the thermometer leaves the factory, and cannot quickly detect all the scale lines and values ​​on the thermometer. The invention provides a thermometer scale magnification and detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention discloses a thermometer scale magnification detection device, comprising a placement detection tube for placing the thermometer to be tested; the placement detection tube is made of transparent material; symmetrical grooves are formed inside the placement detection tube; a lens plate is fixedly connected inside the symmetrical grooves; and a convex lens is fixedly connected inside the placement detection tube corresponding to the lens plate.

[0008] Furthermore, a counterweight base plate is fixedly connected to the lower end of the detection tube.

[0009] Furthermore, a counterweight ring is fitted onto the lower end of the detection tube.

[0010] The thermometer scale magnification detection device provided by this utility model has the following beneficial effects:

[0011] 1. This utility model involves vertically inserting a thermometer with the scale line to be tested into a detection tube. When the scale line is aligned with a convex lens, the shape of the thermometer scale line can be directly observed by magnifying the lens. Even when the thermometer scale line is located on the side or behind, the shape of the thermometer scale line can still be observed by magnifying the lens under the reflection of the lens plate. This eliminates the need to rotate the thermometer to align the scale line with the convex lens, reducing one step in the testing process and improving the efficiency of the inspection.

[0012] 2. This utility model utilizes the large area of ​​the counterweight base plate in contact with the ground for support, thereby enabling more stable operation when visually inspecting the thermometer scale by placing the detection tube, ensuring stable operation throughout the entire process; the metal counterweight ring ensures that the detection tube is placed vertically and stably on the plane, maintaining stability even if external forces are accidentally applied to the detection tube during the actual testing process, making the testing process more convenient.

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0021] Please see Figure 1-3 As shown, a thermometer scale magnification detection device includes a placement detection tube 1 for placing the thermometer to be tested; the placement detection tube 1 is made of transparent material; symmetrical grooves 3 are formed inside the placement detection tube 1; a lens plate 4 is fixedly connected inside the symmetrical grooves 3; a convex lens 5 is fixedly connected inside the placement detection tube 1 corresponding to the lens plate 4. By vertically inserting the thermometer with the scale line to be tested into the placement detection tube 1, when the scale line is aligned with the convex lens 5, the shape of the thermometer scale line can be directly observed by magnifying the convex lens 5. When the thermometer scale line is located on the side or behind, the shape of the thermometer scale line can still be observed by magnifying the convex lens 5 under the reflection of the lens plate 4. This eliminates the need to rotate the thermometer to align the scale line with the convex lens 5, reducing one action during detection and improving the efficiency of the inspection.

[0022] The lower end of the placement detection tube 1 is fixed with a counterweight base plate 2. The large area of ​​the counterweight base plate 2 is in contact with the ground, which makes the operation more stable when visually inspecting the scale of the thermometer by placing the detection tube 1, so that the whole process remains stable.

[0023] A counterweight ring 6 is fitted to the lower end of the test tube 1. The metal counterweight ring 6 ensures that the test tube 1 is placed vertically and stably on the plane. In the actual testing process, the test tube 1 can be kept stable even if there is an external force that is accidentally applied, making the testing process more convenient.

[0024] A limiting tube 7 is sleeved on the upper end of the placement detection tube 1. The limiting tube 7 serves as a guide structure, allowing the thermometer to be accurately placed into the placement detection tube 1 for testing, thus improving testing efficiency.

[0025] The side of the limiting tube 7 has a through hole with a threaded fastener 8. By rotating the fastener 8, the limiting tube 7 is stably fixed at the upper end of the detection tube 1, which makes the insertion process of the guide thermometer more stable and reduces the risk of jerking and disintegration.

[0026] The limiting tube 7 has a guide groove 9 corresponding to the lens plate 4 and the convex lens 5. The guide groove 9 prevents the thermometer from colliding with the lens plate 4 and the convex lens 5 when it is inserted, thus avoiding scratches and damage. This allows for faster detection of the thermometer's scale and enables visual magnification to check the accuracy of the scale lines.
