[0025] The following is combined with Figure 1-3 This application is described in further detail.

[0026] The present application embodiment discloses a device for installing and positioning a civil air defense door frame. Figure 1 and Figure 2 The installation and positioning device of the civil air defense door frame includes a bottom plate 1, the bottom wall of the bottom plate 1 is provided with a groove 12 for clamping with the bottom of the civil air defense door frame; a measuring rod 2 is arranged on the bottom plate 1, the measuring rod 2 is located outside the civil air defense door frame, the measuring rod 2 spans the bottom plate 1, and the bottom plate 1 is located at the center of the measuring rod 2, the length direction of the measuring rod 2 is parallel to the horizontal length direction of the civil air defense door frame, and the measuring rod 2 is fixedly provided with scales 3 along the center of the bottom plate 1 to both ends, and the length direction of the scales 3 is parallel to the length direction of the measuring rod 2. The rest of the structure on the bottom plate 1 is the same as that in the related art.

[0027] When in use, first stand the civil air defense door frame in the door opening of the wall, place the base plate 1 on the installation ground, so that the groove 12 of the base plate 1 is pressed against the bottom of the civil air defense door frame, and then move the base plate 1 so that the edges of the two sides of the door opening are aligned with the same scale 3 on the measuring rod 2, thereby adjusting the base plate 1 to the middle position of the door opening, and then the base plate 1 stops moving, and adjusts the position of the adjustment plate on the base plate 1 so that the pressure plates on both sides press the side walls of the civil air defense door frame tightly. Since the base plate 1 is located in the middle position of the door opening, the pressure plates on the base plate 1 are at an equal distance from the center of the base plate 1, so that the pressure plates on both sides of the base plate 1 can position the civil air defense door frame in the middle of the door opening, thereby helping to ensure the accurate positioning of the civil air defense door frame.

[0028] Reference Figure 2 and Figure 3 A slide groove 14 is provided on the upper surface of the measuring rod 2. The cross section of the slide groove 14 is T-shaped. The length direction of the slide groove 14 is parallel to the length direction of the measuring rod 2. Two T-shaped blocks 15 are relatively slidably arranged at both ends of the slide groove 14. The sliding direction of the T-shaped block 15 is parallel to the length direction of the measuring rod 2. A pointer 4 is fixed to the top wall of each T-shaped block 15, so that the T-shaped block 15 can drive the corresponding pointer 4 to slide along the length direction of the measuring rod 2; the pointer 4 extends toward the side close to the center of the bottom plate 1, and a driving member is provided on the measuring rod 2 for driving the two T-shaped blocks 15 to drive the corresponding pointers 4 to move closer to or away from each other.

[0029] Reference Figure 2 and Figure 3 In order to facilitate driving the two T-shaped blocks 15 to drive the corresponding pointers 4 to move closer to or away from each other, the driving member includes a bidirectional screw 5, which is rotatably inserted into the slide groove 14. The rotation axis of the bidirectional screw 5 is parallel to the length direction of the measuring rod 2. The two T-shaped blocks 15 are respectively threadedly sleeved on both ends of the bidirectional screw 5. A handle 16 is fixed to one end of the bidirectional screw 5 located outside the measuring rod 2 to facilitate the rotation of the bidirectional screw 5.

[0030] When in use, by rotating the handle 16, the handle 16 drives the bidirectional screw 5 to rotate, and the bidirectional screw 5 drives the two T-shaped blocks 15 to drive the corresponding pointers 4 to move closer or farther away from each other, and then the base plate 1 is moved so that the two pointers 4 point to the two side edges of the door opening respectively. Since the distances between the two pointers 4 and the center of the base plate 1 are equal, the base plate 1 is located in the center of the door opening. The pointer 4 extends the measuring rod 2, which can be more conveniently aligned with the edge of the door opening, facilitating the observation of the operator, so that the civil defense door frame supported by the base plate 1 can be located in the center of the door opening, ensuring the accurate positioning of the civil defense door opening.

[0031] Reference Figure 2A slot 7 is provided on one side of the bottom plate 1, and a support rod 6 is inserted into the slot 7. The support rod 6 is located outside the civil air defense door frame, and the support rod 6 is arranged in the vertical direction. The measuring rod 2 is arranged on the side of the top of the support rod 6 close to the center of the bottom plate 1. A first Velcro 8 is fixed to the bottom wall of the support rod 6, and a second Velcro 9 is fixed to the bottom wall of the slot 7. The second Velcro 9 is used to bond with the first Velcro 8. In other embodiments, the first Velcro 8 and the second Velcro 9 can be replaced by two magnets that are mutually attracted and matched, and the relative fixation of the support rod 6 and the bottom wall of the slot 7 can also be achieved by the two magnets.

[0032] Insert the support rod 6 into the slot 7, and fix the support rod 6 and the bottom plate 1 relatively by bonding the first Velcro 8 and the second Velcro 9, so that the support rod 6 is not easy to fall over; by setting the support rod 6, the measuring rod 2 is located at a certain height, which is convenient for observing whether the pointer 4 is aligned with the edge of the door opening. On the one hand, there is no need to bend down to adjust, which is convenient for operation; on the other hand, there is sufficient light and observation is easy. After use, pull the support rod 6 out of the slot 7 with force to separate the support rod 6 from the bottom plate 1, which is convenient for the separate transportation and storage of the bottom plate 1 and the measuring rod 2.

[0033] Reference Figure 2 and Figure 3 The measuring rod 2 is rotatably arranged on one side of the support rod 6 close to the center of the base plate 1, and the rotation axis of the measuring rod 2 is perpendicular to the length direction of the measuring rod 2. A fixed shaft 17 is fixed to one side of the upper end of the support rod 6 close to the center of the base plate 1, and the length direction of the fixed shaft 17 is parallel to the rotation axis of the measuring rod 2. A connecting block 18 is fixed to the bottom wall in the middle of the measuring rod 2, and the connecting block 18 is rotatably sleeved on the fixed shaft 17. A fixing part for fixing the measuring rod 2 and the support rod 6 relative to each other is provided on the support rod 6.

[0034] Reference Figure 2 and Figure 3 In order to facilitate the relative fixation of the measuring rod 2 and the support rod 6, the fixing part includes an insertion rod 10, which is slidably inserted into the support rod 6 and the fixed shaft 17. The sliding direction of the insertion rod 10 is parallel to the rotation axis of the measuring rod 2. The cross-section of the insertion rod 10 is polygonal. In the embodiment of the present application, the cross-section of the insertion rod 10 is square; a hole 11 for the insertion rod 10 to pass through is provided on one side of the connecting block 18 close to the center of the bottom plate 1. When the measuring rod 2 is perpendicular to the support rod 6, the hole 11 is aligned with the insertion rod 10.

[0035] When it is needed, remove the rod 10 from the socket 11, rotate the measuring rod 2 so that the measuring rod 2 is in a horizontal state, the measuring rod 2 is perpendicular to the support rod 6, and the scale 3 and pointer 4 on the measuring rod 2 are upward. At this time, the socket 11 on the connecting block 18 is aligned with the rod 10, and the rod 10 is moved toward the direction close to the socket 11 so that the rod 10 passes through the socket 11. Since the rod 10 is a square rod, the rotation of the measuring rod 2 is limited, so that the measuring rod 2 and the support rod 6 are relatively fixed, so as to facilitate the positioning of the bottom plate 1 and the civil defense door frame. When use is completed, remove the rod 10 from the socket 11, rotate the measuring rod 2 so that the measuring rod 2 is parallel to the support rod 6, which further facilitates the transportation and storage of the measuring rod 2 and reduces the occupied space.

[0036] Reference Figure 2 The bottom wall of the groove 12 is embedded with a plurality of balls 13 for contacting the upper surface of the bottom of the civil air defense door frame, and the plurality of balls 13 are arranged in a matrix. When in use, the bottom plate 1 is placed on the installation ground, so that the groove 12 is engaged with the bottom of the civil air defense door frame, and the balls 13 are in contact with the bottom of the civil air defense door frame. On the one hand, the civil air defense door frame is not easy to tilt, and on the other hand, the pressure plate on the bottom plate 1 is pressed against the civil air defense door frame. When the civil air defense door frame is driven to move horizontally, the civil air defense door frame can slide relative to the bottom plate 1, and it is not easy to drive the bottom plate 1 to move together.

[0037] The implementation principle of the embodiment of the present application is: when in use, first stand the civil defense door frame in the door opening of the wall, place the base plate 1 on the installation ground, so that the groove 12 of the base plate 1 is pressed against the bottom of the civil defense door frame, and the ball 13 is in contact with the upper surface of the bottom of the civil defense door frame, and then the support rod 6 is inserted into the slot 7, so that the measuring rod 2 is located on the side of the support rod 6 close to the center of the base plate 1, and the first Velcro 8 is bonded with the second Velcro 9; then move the insertion rod 10 out of the socket 11, rotate the measuring rod 2, so that the measuring rod 2 is in a horizontal state, and the scale 3 and pointer 4 on the measuring rod 2 are facing upward, at this time, the socket 11 on the connecting block 18 is aligned with the insertion rod 10, and then move the insertion rod 10 in the direction close to the socket 11, so that the insertion rod 10 passes through the socket 11, thereby limiting the rotation of the measuring rod 2.

[0038] Then rotate the handle 16, the handle 16 drives the bidirectional screw 5 to rotate, the bidirectional screw 5 drives the two T-shaped blocks 15 to drive the corresponding pointers 4 to move closer or farther away from each other, and move the base plate 1 so that the two pointers 4 point to the two side edges of the door opening respectively. Since the distances between the two pointers 4 and the center of the base plate 1 are equal, the base plate 1 is located in the center of the door opening. Then the base plate 1 no longer moves, and the position of the adjustment plate on the base plate 1 is adjusted so that the pressure plates on both sides press the side walls of the civil air defense door frame tightly. Since the base plate 1 is located in the middle position of the door opening, the pressure plates on both sides of the base plate 1 can position the civil air defense door frame in the middle position of the door opening, thereby helping to ensure the accurate positioning of the civil air defense door frame.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
