Specific embodiments

[0031] 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.

[0032] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and 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 thus cannot be construed as a limitation to the present utility model.

[0033] In this embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 , the present utility model provides a technical solution: including a base plate 1, a heat containment bin 2 and a transmission bin 3. A heat containment bin 2 is arranged on the left side of the upper end surface of the base plate 1, and a transmission bin 3 is installed on the right side of the upper end surface of the base plate 1. In addition, a dial 43 is fixedly arranged at the rear end of the right side of the upper end surface of the base plate 1. Moreover, an external connection pipe 21 is arranged in the middle of the left end of the heat containment bin 2, and a fixed rod 31 is fixedly installed at the front end of the lower side inside the transmission bin 3;

[0034] Among them, the base plate 1 is used to provide a relatively stable placement function for the overall device. At the same time, the material of the base plate 1 is hard rubber, which can provide good grounding friction function. The heat storage chamber 2 inputs the thermal expansion air pressure generated by the pressure-bearing part into its interior through the external connecting pipe 21. The transmission chamber 3 is used to provide a protection function for the internal transmission parts. The dial 43 is used to enable the user to directly observe the thermal expansion amount. The fixing rod 31 is used to provide a support and stability function for the right end of the heat storage chamber 2. The base plate 1 is fixedly installed with the heat storage chamber 2, the transmission chamber 3, and the dial 43 respectively by existing fixing methods. The heat storage chamber 2 and the external connecting pipe 21 are fixedly installed by existing flanges. The transmission chamber 3 and the fixing rod 31 are fixedly installed by existing screws.

[0035] Further, please refer to Figure 1 and Figure 2 , the sealing component is composed of a first sealing block 221, a second sealing block 222, and a connecting rod 223. The first sealing block 221 is arranged at the inner right end of the heat storage chamber 2. At the same time, the second sealing block 222 is fixedly installed on the right end face of the first sealing block 221. In addition, the connecting rod 223 is fixedly arranged at the right end face of the second sealing block 222 and penetrates through the right end of the heat storage chamber 2 and is installed inside the fixing rod 31;

[0036] Among them, the first sealing block 221 and the second sealing block 222 form an integrated structure, and at the same time provide a sealing function for the internal space of the heat storage chamber 2, dividing the inner part of the heat storage chamber 2 into left and right two parts of space. The first sealing block 221 and the second sealing block 222 provide a double sealing function for the inside of the heat storage chamber 2, making its sealing effect more perfect. The connecting rod 223 is slidably connected with the fixing rod 31. When the heat in the left side of the heat storage chamber 2 compresses the air and makes its volume expand, it will push the first sealing block 221 and the second sealing block 222 to move to the right, so that the connecting rod 223 moves synchronously to the right with it.

[0037] Further, please refer to Figure 1 , Figure 2 and Figure 3 , the transmission component is composed of a connecting rod 321, a first connecting disk 322, and a second connecting disk 323. The connecting rod 321 is arranged inside the clamping block at the upper end of the transmission chamber 3. At the same time, the first connecting disk 322 is fixedly installed at the left end of the connecting rod 321 and is connected with the connecting rod 223 inside the fixing rod 31. In addition, the second connecting disk 323 is fixedly arranged at the right end of the connecting rod 321 and is connected with the connecting disk 41. The connecting disk 41 is arranged at the rear lower side inside the transmission chamber 3. Furthermore, the pointer 42 is installed inside the dial 43 at the rear right side of the upper end face of the base plate 1 and is connected with the rear end face of the connecting disk 41;

[0038] Among them, the first connecting disk 322 meshes with the connecting rod 223. The connecting rod 321, the first connecting disk 322 and the second connecting disk 323 together form an integrated structure, so that the connecting rod 321, the first connecting disk 322 and the second connecting disk 323 can rotate synchronously. Both the front and rear ends of the connecting rod 321 are arranged in the clamping blocks on the upper side inside the transmission bin 3, so as to have a limiting function. The second connecting disk 323 meshes with the connecting disk 41, so that the connecting disk 41 can rotate synchronously with the second connecting disk 323. A limiting plate is arranged at the front end of the connecting disk 41, and a pointer 42 is fixedly installed at the rear end of the connecting disk 41 by an existing method, so that the pointer 42 can rotate synchronously with the connecting disk 41.

[0039] Working principle: Connect the external connecting pipe 21 to the pressure-bearing member in the external object whose thermal expansion amount needs to be measured, so that the space on the left side inside the heat storage bin 2 is independently divided left and right. When the thermal expansion amount on the left side of the heat storage bin 2 is too high, the heat expansion will cause the first sealing block 221 and the second sealing block 222 to move to the right, so that the connecting rod 223 moves to the right. The connecting rod 223 drives the first connecting disk 322 to rotate through its engagement with the first connecting disk 322. Then the first connecting disk 322 drives the second connecting disk 323 to rotate through the connecting rod 321, and further makes the second connecting disk 323 drive the connecting disk 41 to rotate synchronously. Finally, the pointer 42 on the rear end face of the connecting disk 41 is used for pointer-type numerical display.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
