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

[0002] The bimetallic thermometer combines two metals with different linear expansion coefficients, with one end fixed. When the temperature changes, the two metals expand differently, driving the pointer to deflect to indicate the temperature. This is a bimetallic thermometer, as shown in the figure on the previous page. The temperature measurement range is -80~500C, and it is suitable for temperature measurement in industry when the accuracy requirements are not high.

[0026] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The technical solution in the embodiment of the present application effectively solves the technical problem that the display screen of the bimetallic thermometer accumulates a lot of dust after long-term use, so that the operator needs to clean the screen before observing the thermometer, which increases the workload of the staff. The overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a bimetallic thermometer, which comprises a thermometer body 1, and a protective mechanism is arranged outside the thermometer body 1;

[0028] The protection mechanism includes a protection plate 2, a fixing plate 3, a mounting groove 4, a connecting plate 5, a groove 6, a limiting plate 7 and a first spring 8;

[0029] The protective plate 2 is clamped on the outside of the thermometer body 1, the fixed plate 3 is arranged on the outside of the thermometer body 1, the mounting groove 4 is opened on the outside of the fixed plate 3, one end of the connecting plate 5 is slidably connected to the inside of the mounting groove 4, and the other end of the connecting plate 5 is fixedly connected to the outside of the protective plate 2, the groove 6 is opened in the inside of the mounting groove 4, the limit plate 7 is slidably connected to the inside of the groove 6, one end of the first spring 8 is fixedly connected to the inside of the groove 6, and the other end of the first spring 8 is fixedly connected to the outside of the limit plate 7.

[0030] By setting the protection plate 2 and cooperating with the limit plate 7, when checking the thermometer data, pull the connecting plate 5 so that one end of the connecting plate 5 is located in the installation groove 4, squeeze the limit plate 7 so that the limit plate 7 enters the inside of the groove 6. At this time, the first spring 8 is compressed. At this time, continue to pull the connecting plate 5 to release the connection between the connecting plate 5 and the installation groove 4. At this time, the connection between the protection plate 2 and the thermometer is released. At this time, the staff can check the data. When the checking is completed, align one end of the connecting plate 5 with the inside of the installation groove 4, and push the connecting plate 5. At this time, due to the special shape of the limit plate 7, as the connecting plate 5 moves, the connecting plate 5 squeezes the limit plate 7 so that the limit plate 7 enters the inside of the groove 6 When the connection between the connecting plate 5 and the limiting plate 7 is released, the limiting plate 7 pops outward under the action of the spring. At this time, the position of the connecting plate 5 is limited. At this time, the protective plate 2 is clamped on the outside of the thermometer. At this time, since the side of the protective plate 2 away from the connecting plate 5 is in contact with the thermometer display screen and fills the inner side of the shell close to the display screen, the probability of the shell sinking inward when hit is reduced, and the shell sinking is prevented from blocking the screen and affecting the staff's viewing of data. At the same time, the protective plate 2 covers the display screen to prevent dust from accumulating on the outside of the display screen, eliminating the cleaning work of the staff when viewing the data, and reducing the probability of damage to the display screen.

[0031] The groove 6 has two built-in grooves 13 formed therein, and the two built-in grooves 13 are both slidably connected with built-in plates 9;

[0032] The two built-in plates 9 are both fixedly mounted on a side of the limiting plate 7 close to the first spring 8 to limit the moving path of the limiting plate 7 .

[0033] A protective pad 10 is fixedly mounted on the outside of the protective plate 2;

[0034] The protective pad 10 fits the thermometer body 1 to prevent the protective plate 2 from damaging the display screen.

[0035] A threaded rod 11 is provided on the outside of the thermometer body 1;

[0036] One end of the fixing plate 3 away from the mounting groove 4 is threadedly connected to the outside of the threaded rod 11 , so as to facilitate the disassembly and assembly of the fixing plate 3 .

[0037] A placement groove 12 is provided on the outside of the thermometer body 1;

[0038] The threaded rod 11 is fixedly installed inside the placement groove 12 to prevent the threaded rod 11 from protruding.

[0039] A magnetic attraction plate 14 is fixedly mounted on one side of the mounting groove 4 close to the connecting plate 5, and an iron sheet 15 is fixedly mounted on one side of the connecting plate 5 close to the magnetic attraction plate 14;

[0040] The magnetic attraction plate 14 fits the outside of the iron sheet 15 to strengthen the connection between the connecting plate 5 and the mounting groove 4 .

[0041] By setting the threaded rod 11 and cooperating with the fixing plate 3, when the installation environment of the thermometer is narrow, after removing the protective plate 2, the fixing plate 3 is rotated to release the connection between the fixing plate 3 and the threaded rod 11. At this time, the external structure protruding from the thermometer is removed, and the threaded rod 11 is located inside the placement groove 12 without affecting the installation of the thermometer. The detachable fixing plate 3 is convenient for the staff to adjust according to the installation environment, thereby reducing the difficulty of installation.

[0042] Working principle:

[0043] By setting the protective plate 2 and cooperating with the limit plate 7, when checking the thermometer data, the connecting plate 5 is pulled so that one end of the connecting plate 5 located in the installation groove 4 squeezes the limit plate 7 so that the limit plate 7 enters the interior of the groove 6. At this time, the first spring 8 is compressed, and the connection between the magnetic plate 14 and the iron sheet 15 is released. At this time, the connecting plate 5 is continued to be pulled to release the connection between the connecting plate 5 and the installation groove 4. At this time, the connection between the protective plate 2 and the thermometer is released, and the staff can check the data at this time;

[0044] After checking, align one end of connecting plate 5 with the inside of mounting groove 4, and push connecting plate 5 at this time. At this time, due to the special shape of limit plate 7, as connecting plate 5 moves, connecting plate 5 squeezes limit plate 7 to make limit plate 7 enter the inside of groove 6. At this time, first spring 8 is compressed. When the connection between connecting plate 5 and limit plate 7 is released, limit plate 7 pops up outward under the action of spring. At this time, the position of connecting plate 5 is limited. At this time, magnetic suction plate 14 is in contact with the outside of iron sheet 15. At this time, protective plate 2 is clamped on the outside of thermometer. At this time, because the side of protective plate 2 away from connecting plate 5 is in contact with the display screen of thermometer and fills the inner side of the shell close to the display screen, the probability of the shell sinking inward when impacted is reduced, and the shell sinking is prevented from blocking the screen and affecting the staff to view data. At the same time, protective plate 2 covers the display screen so that dust cannot accumulate on the outside of the display screen, eliminating the cleaning work of the staff when viewing data, and reducing the probability of damage to the display screen.

[0045] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
