[0024] Example 1

[0025] Reference Figure 1 and Figure 3 , which is the first embodiment of the utility model, provides an observation device that can be installed in a boiler fire observation hole, including:

[0026] The bearing mechanism 100 comprises a door frame 101, and a fire viewing hole outer frame 102 is fixedly mounted on the inner surface of the door frame 101;

[0027] The door frame 101 is used to support the fire viewing hole outer frame 102 .

[0028] The locking mechanism 200 includes a card slot guide rail 201 provided on the upper and lower sides of the inner surface of the door frame 101 , and a filter glass 202 is hinged on the inner surface of the card slot guide rail 201 .

[0029] The card slot track 201 is used to support the filter glass 202, and the filter glass 202 is made of a dark-colored, high-temperature-resistant material.

[0030] Specifically, the supporting mechanism 100 further includes a fire viewing hole 103 provided on the surface of the fire viewing hole outer frame 102 , and a fire viewing hole door 104 is hingedly connected to one side surface of the fire viewing hole outer frame 102 .

[0031] The fire viewing hole 103 is used to allow the staff to observe the environment inside the boiler, and the fire viewing hole door 104 is used to open or close the fire viewing hole 103.

[0032] Furthermore, the supporting mechanism 100 also includes a fire viewing door handle 105 adapted to be installed on a side surface of the fire viewing hole door 104, and a plurality of ear pieces 106 are distributed in an array on the outer surface of the door frame 101.

[0033] The fire-off door handle 105 is used to open or close the fire-viewing hole door 104 , and the ear piece 106 is used to install the door frame 101 .

[0034] When in use, align the fire viewing hole 103 on the surface of the fire viewing hole outer frame 102 with the fire viewing hole on the boiler surface, install the door frame 101 on the boiler surface through the ear piece 106, and then open the fire viewing hole door 104 through the fire viewing door handle 105.

[0035] In summary, the supporting mechanism 100 can be designed to install the slot guide rail according to the fire viewing hole frame, and the fire viewing hole frame can be installed on the surface of the boiler fire viewing hole through the ear piece. The installation process is relatively simple and does not require additional tools. It can reduce the installation time and labor costs to a certain extent, thereby improving the overall installation efficiency and reducing unnecessary costs.

[0036] Example 2

[0037] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides the structure and function of the locking mechanism.

[0038] Specifically, the locking mechanism 200 further includes a filter movable handle 203 adapted to be installed on one side surface of the filter glass 202 , and a connecting column 204 is fixedly connected to the other side surface of the filter glass 202 .

[0039] The movable handle 203 is used to move the filter glass 202 , and the filter glass 202 is used to support the connecting column 204 .

[0040] Furthermore, the locking mechanism 200 also includes a hinge column 205 fixedly connected to the other end of the connecting column 204 , a hinge ring 206 is hinged on the surface of the hinge column 205 , and a fixing block 207 is fixedly connected to the other end of the hinge column 205 .

[0041] The connecting column 204 is used to support the hinge column 205 , and the hinge column 205 is used to support the hinge ring 206 and the fixing block 207 .

[0042] Preferably, the locking mechanism 200 further includes a hinge groove 208 formed on one side of the inner surface of the door frame 101 , and a limiting groove 209 is formed on the upper surface of the hinge groove 208 .

[0043] It should be noted that the locking mechanism 200 further includes a spring 210 fixedly connected to a surface of one side of the limiting groove 209 , and the other end of the spring 210 is fixedly connected to a limiting block 211 , and the limiting block 211 is hinged in the limiting groove 209 .

[0044] The limiting groove 209 is used to support the spring 210 , and the spring 210 is used to connect the limiting block 211 .

[0045] When in use, after opening the fire viewing hole 103, the filter glass 202 in the slot track 201 is pulled to the center of the fire viewing hole 103, and at the same time, the filter glass 202 drives the connecting column 204 to move toward the hinge groove 208. When the filter glass 202 is in the center of the fire viewing hole 103, the connecting column 204 cooperates with the hinge column 205 to drive the fixing block 207 to squeeze the limit block 211, so that the limit block 211 is squeezed into the limit When the fixed block 207 is completely moved to the other side of the limit block 211, the limit block 211 and the spring 210 will lose the pressure of the fixed block 207. At this time, the limit block 211 is squeezed out of the limit groove 209 by the reaction force of the spring 210, so that the plane of the limit block 211 limits the plane of the fixed block 207. When the fire-watching work is completed, it moves toward the hinge groove 208 again. The filter glass 202 is pushed, so that the filter glass 202 drives the connecting column 204 to extend into the inner direction of the hinge groove 208. Through the movement of the connecting column 204, the hinge ring 206 applies a pressure to the limit block 211, and the limit block 211 is squeezed into the limit groove 209. At the same time, the limit block 211 applies a pressure to the spring 210. When the hinge ring 206 is completely moved to the other side of the limit block 211, the filter glass 202 is pulled away from the hinge groove 208. 02, the filter glass 202 drives the connecting column 204, the hinge column 205 and the fixed block 207 to move, and the hinge ring 206 will be stagnant due to the limitation of the limit block 211. When the groove opened by the plane lock of the fixed block 207 is moved to a position that fits the surface of the hinge ring 206, the limit block 211 is squeezed into the limit groove 209 again through the cooperation of the fixed block 207 and the inclined surface of the hinge ring 206, thereby releasing the limit of the filter glass 202.

[0046] In summary, the design of the locking mechanism 200 can install a laterally movable filter glass 202 in the slot track 201. After opening the fire viewing hole 103, the filter glass 202 in the slot track 201 is pulled to the center of the fire viewing hole 103. While preventing positive pressure, it can shield the glaring light, and the state of the combustion and heating surface in the furnace can be observed more clearly. At the same time, a quick locking function is added to the filter glass 202, which can avoid leakage, looseness or other safety hazards during operation of the device to a certain extent.
