Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense doors, in particular to a door frame measuring device for civil air defense doors. Background Art

[0002] The civil air defense door is the door at the entrance and exit of the people's defense project. When the civil air defense door is processed, the door frame is measured to ensure that the size and flatness of the civil air defense door are within the qualified range, which is convenient for subsequent installation and use.

[0003] In the prior art, when measuring door frames, the dimensions of the door frames are usually measured by a tape measure to ensure that the dimensions of the door frames are within the qualified dimensions, and then the flatness of the door frames is checked by a level. When deviations occur, adjustments are made. When the door frames are adjusted and trimmed, the dimensions and flatness of the door frames change. When it is necessary to verify whether they are within the appropriate range, the dimensions and flatness need to be measured again, resulting in a cumbersome overall measurement process. At the same time, measurements relying on manual handheld instruments are prone to deviations, resulting in inaccurate dimensions. Therefore, we propose a measuring device for civil air defense door frames. Utility Model Content

At this time, the fixing frame 2 is fitted with both sides of the door frame body 1, and then the clamping seat 5 and the fixing frame 2 are clamped with the door frame body 1 through the rebound of the spring 702, thereby ensuring the connection between the fixing frame 2 and the clamping seat 5 and the door frame body 1, thereby facilitating the pressure sensor 3 and the distance sensor 4 to move on the door frame body 1 to measure the door frame body 1, measure the flatness of the door frame body 1 through the pressure sensor 3, and measure the size of the door frame body 1 through the distance sensor 4, complete the simultaneous measurement, and observe the changes in time.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The utility model embodiment discloses a device for measuring a door frame of a civil air defense door.

[0027] According to the attached Figure 1-3 As shown, it includes a door frame body 1 and a fixing frame 2, and the fixing frame 2 is fitted with the door frame body 1; a fixing seat 201 is fixedly connected to the fixing frame 2, and a pressure sensor 3 and a distance sensor 4 are installed on the fixing seat 201. The pressure sensor 3 is fitted with the door frame, and the flatness of the door frame body 1 is effectively observed under the pressure change of the pressure sensor 3. At the same time, when the pressure sensor 3 moves, the distance sensor 4 moves accordingly. At this time, the distance sensor 4 moves along the door frame body 1 to measure the size on the door frame body 1 to detect whether there is a deviation. The fixing frame 2 is provided with:

[0028] The clamping assembly includes a clamping seat 5 and a threaded rod 7. The clamping seat 5 is slidably connected to the outer peripheral wall of the threaded rod 7, and the threaded rod 7 is slidably connected to the inner wall of the fixing frame 2. The clamping assembly is clamped with the door frame body 1 through the clamping seat 5 and the fixing frame 2. By pulling the fixing frame 2, the fixing frame 2 slides along the outer peripheral wall of the threaded rod 7. At this time, the fixing frame 2 is fitted with both sides of the door frame body 1, and then the clamping seat 5 and the fixing frame 2 are clamped with the door frame body 1 through the rebound of the spring 702 to ensure the connection between the fixing frame 2 and the clamping seat 5 and the door frame body 1, thereby facilitating the pressure sensor 3 and the distance sensor 4 to move on the door frame body 1 to measure the door frame body 1, measure the flatness of the door frame body 1 through the pressure sensor 3, and measure the size of the door frame body 1 through the distance sensor 4, complete the simultaneous measurement, and observe the changes in time.

[0029] A mounting base 202 is fixedly connected to the outer wall of the fixing base 201. The mounting base 202 and the distance measuring sensor 4 are fixed by bolts. The distance measuring sensor 4 is installed on the fixing base 201 through the mounting base 202. Under the action of the mounting base 202, the distance measuring sensor 4 is stably installed on the fixing base 201, which is convenient for the normal use of the distance measuring sensor 4.

[0030] A connecting seat 6 is provided corresponding to the fixing seat 201, and the connecting seat 6 is fitted with the other side of the door frame body 1. A pulley is rotatably connected to the inner wall of the connecting seat 6. When the clamping seat 5 is pulled to drive the fixing seat 201 and the fixing frame 2 to slide on the door frame body 1, the pulley on the connecting seat 6 is fitted with the door frame body 1, which facilitates the overall movement of the fixing frame 2, the fixing seat 201 and the clamping seat 5.

[0031] The connecting seat 6 is fixedly connected to the clamping seat 5, and the outer wall of the clamping seat 5 is fitted with a nut seat 703, which is threadedly connected to the threaded rod 7. When the clamping seat 5 and the fixing seat 201 are not clamped stably on the door frame body 1, the nut seat 703 is rotated along the outer wall of the threaded rod 7, and the clamping seat 5 and the fixing frame 2 are fitted with both sides of the door frame body 1.

[0032] One end of the threaded rod 7 is fixedly connected to a contact seat 701, and the contact seat 701 is slidably connected to the inner wall of the fixing frame 2. At this time, the nut seat 703 rotates, driving the threaded rod 7 to slide along the inner wall of the fixing frame 2. As the threaded rod 7 moves, the contact seat 701 moves accordingly.

[0033] A spring 702 is fixedly connected to the outer wall of the contact seat 701, and the other end of the spring 702 is fixedly connected to the inner wall of the fixing frame 2. The spring 702 is sleeved on the outer peripheral wall of the threaded rod 7. When the contact seat 701 moves to further squeeze the spring 702, the spring 702 rebounds, and the clamping seat 5 and the fixing frame 2 are pulled to clamp the two sides of the door frame body 1 more tightly, thereby ensuring the stability of the fixing frame 2 and the clamping seat 5 and the door frame body 1.

[0034] At this time, the clamping seat 5 is pulled to drive the fixing frame 2 and the fixing seat 201 to slide along the door frame body 1, and the pressure sensor 3 and the distance sensor 4 on the fixing seat 201 move downward at the same time, and then the pressure sensor 3 and the distance sensor 4 move along the door frame body 1, the pressure sensor 3 measures the flatness of the door frame body 1, and the distance sensor 4 measures the size of the door frame body 1;

[0035] When the measurement is completed, the threaded rod 7 is moved by pulling the clamping seat 5. At this time, the threaded rod 7 moves to separate the clamping seat 5 from the door frame body 1, and the clamping seat 5 and the fixing frame 2 can be separated from the door frame body 1 and removed.
