[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] In the present utility model, unless otherwise clearly defined and limited, the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0018] Such as Figures 1-4As shown in the figure, a quick-installation pointer-type square-shell thermometer includes a meter head 1, a temperature-sensing element 2 is arranged below the meter head 1, and a sleeve 3 is also included. A connection structure 4 for fixing the temperature-sensing element 2 is arranged between the temperature-sensing element 2 and the sleeve 3, and threads matching the installation part are arranged outside the sleeve 3. The temperature-sensing element 2 is a commonly used temperature-sensing element of a bimetal thermometer. A heat bimetal sheet wound into a spiral shape is used as the temperature-sensing device. One end of it is fixed, called the fixed end, and the other end is connected to a thin shaft, called the free end. A pointer inside the meter head 1 is connected to the free-end spool. When the temperature changes, the free end of the temperature-sensing device rotates accordingly, driving the pointer to generate an angular change and indicating the corresponding temperature on the scale dial. The pipeline or valve at the installation location is provided with internal threads matching the threads outside the sleeve 3, and the sleeve 3 can be fixed on the pipeline or valve through the threaded fit. When installing the thermometer, only need to insert the temperature-sensing element 2 into the sleeve, and cooperate with the sleeve 3 through the connection structure 4 to fix the temperature-sensing element 2 in the sleeve 3 to complete the installation of the thermometer. The sleeve 3 is preferably a copper sleeve because copper has good heat transfer effect, making the data measured by the thermometer more accurate.

[0019] For the described quick-installation pointer-type square-shell thermometer, the fixed connection structure 4 includes elastic claws 21 circumferentially arranged at the tail end of the temperature-sensing element 2, and the number of the elastic claws is at least two. The elastic claws 21 cooperate with the inner wall of the sleeve 3 to play a role in fixing the temperature-sensing element 2. Setting the elastic claws 21 at the tail end increases the stroke of the elastic claws 21 when being pulled out, making it more difficult for the temperature-sensing element to come out. The elastic claws 21 are evenly arranged circumferentially to make the fixation more stable.

[0020] For the described quick-installation pointer-type square-shell thermometer, the connection structure 4 includes a silica gel ring 22 arranged at the top of the temperature-sensing element 2. The silica gel ring 22 has an interference fit with the inner surface of the sleeve 3, and the silica gel ring 22 is at least one. The silica gel ring 22 has elasticity and has an interference fit with the inner wall of the sleeve 3. It can not only fix the temperature-sensing element 2, but also seal the upper opening of the sleeve 3, so that heat cannot escape from the upper opening of the sleeve 3, seal the heat inside the copper sleeve, reduce heat loss, and make the temperature measurement more accurate.

[0021] For the described quick-installation pointer-type square-shell thermometer, an annular groove 23 is arranged above the temperature-sensing element 2, and the silica gel ring 22 is located in the annular groove 23. The function of the annular groove 23 is to limit the position of the silica gel ring 22 and prevent the silica gel ring 22 from moving up and down. When multiple silica gel rings 23 are provided, the number of annular grooves 23 is equal to the number of silica gel rings 22, and one silica gel ring 22 is arranged in each annular groove 23.

[0022] The described quick-installation pointer-type square-case thermometer has an adjustable warning pointer 11 provided on the thermometer head. Commonly used thermometers usually paint the scale line at the warning temperature red, and when the thermometer pointer points to the red position, the temperature reaches the warning temperature. Different pipelines or valves may have different temperatures, and the warning temperatures may also be different. The same thermometer cannot be used at another position. Therefore, an adjustable warning pointer 11 is provided. When the temperature measurement position needs to be changed, the head can be opened, and the warning pointer 11 can be manually adjusted to the position of the warning temperature scale line to achieve the warning effect. Two warning pointers can be set, corresponding to the upper and lower limits of the temperature range.

[0023] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the overall concept of the present invention, several changes and improvements can still be made, and these should also be regarded as the protection scope of the present invention.
