Description

Technical Field

[0001] The utility model relates to the field of temperature gauge processing, in particular to a tool for installing a rear cover of a temperature gauge. Background Art

[0002] Thermometers are common temperature measuring instruments. Water heater thermometers are a type of thermometer used on water heaters. Their structure mainly includes a main shell, a core, a spring and a back cover. One side of the main shell is the display surface, and the other side is provided with a core groove for placing the core. A columnar mounting piece is provided outside the core groove, and a back cover matching it is installed. A spring is provided between the core and the back cover to press the core to prevent it from being dislocated.

[0003] At present, the connection between the main housing and the rear cover of the thermometer is mainly achieved by clamping the rear cover with a columnar mounting piece. The rear cover is bowl-shaped, the part close to the bowl mouth is cylindrical, and the side close to the bottom of the bowl is a cone surface, which is connected to the bottom of the bowl. The ends of the bowl mouth and the columnar mounting piece are provided with mutually matching clamping protrusions to achieve clamping in turn.

[0004] At present, when installing the back cover of the thermometer, most of them still adopt manual pressing to achieve the snap-in. Some workers will use auxiliary tools such as rubber hammers, but it is still based on manual pressing. This method is relatively primitive, and workers need to do a lot of physical labor, but the snap-in effect cannot be guaranteed. There are many cases of incomplete snap-in and tilted snap-in. The strength and direction of each manual pressing are different, resulting in the inability to produce thermometers with the same specifications. The quality of the finished product after the thermometer is installed cannot be guaranteed, and there are many defective products. Secondly, after long-term labor, the physical strength of the workers gradually decreases, and the installation speed will also slow down. This method of manually installing the back cover has obvious disadvantages and needs to be improved.

[0005] Therefore, in view of the shortcomings of the above scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, a thermometer back cover installation tool is provided to solve the problem of slow manual installation of the thermometer back cover and a large number of defective products.
