[0022] The following is combined with Figure 1-3 This application is described in further detail.

[0023] The present application embodiment discloses a positioning device for an outer handle of a civil air defense door leaf, referring to Figure 1 A positioning device for the outer handle of a civil air defense door comprises a clamping plate 1, a limiting assembly, a mounting frame 2 and a fixing assembly 3. The clamping plate 1 is a plate body with a C-shaped cross section. The gap of the clamping plate 1 is adapted to the thickness of the door leaf, so that the clamping plate 1 can be clamped and connected to the door leaf. The limiting assembly is arranged on the clamping plate 1. When the clamping plate 1 is connected to the door leaf, the limiting assembly is connected to the door leaf and is used to fix the clamping plate 1 to the door leaf. The mounting frame 2 is detachably mounted on the clamping plate 1. The fixing assembly 3 is arranged on the mounting frame 2 and is connected to the door leaf handle. The fixing assembly 3 is used to fix the handle.

[0024] When installing the door leaf handle to the specified position on the door leaf, clamp the clamping plate 1 at the position on the door leaf corresponding to the handle. At this time, the clamping plate 1 is fixed to the door leaf through the limit assembly, and then the position of the handle is aligned and installed on the mounting frame 2. The handle is fixed to the mounting frame 2 through the fixing assembly 3, thereby achieving the effect of fixing the handle; thereafter, the handle is connected to the door lock system and the door leaf installation, and there is no need to manually fix the handle position during the installation process, so that the handle is easy to install on the door leaf.

[0025] Referring to Figure *, the limiting assembly includes a first limiting unit 4 and a second limiting unit 5. When the clamping plate 1 is clamped on the door leaf, the first limiting unit 4 is connected to the door leaf to prevent the clamping plate 1 from moving away from the door leaf, and the second limiting unit 5 is connected to the door leaf and is used to prevent the clamping plate 1 from moving along the length direction of the door leaf.

[0026] Reference Figure 1 and Figure 2 The first limiting unit 4 includes a first limiting block 41 and a first spring 42. The clamping plate 1 includes a web and wing plates on both sides of the web. A first limiting groove 21 is provided on the inner wall of the wing plate of the clamping plate 1. The bottom wall of the first limiting groove 21 is tilted so that the cross-sectional shape of the first limiting groove 21 is a right-angled trapezoid, and the depth of the first limiting groove 21 close to the web of the clamping plate 1 is greater than the depth of the clamping plate 1 away from the web. The first limiting block 41 is a wedge-shaped block, one side of the first limiting block 41 is in contact with the bottom wall of the first limiting groove 21, and the other side of the first limiting block 41 is parallel to the web plane of the clamping plate 1. The first limiting block 41 is slidably disposed in the first limiting groove 21. The first spring 42 is located in the first limiting groove 21 , one end of the first spring 42 is connected to the first limiting block 41 , and the other end is connected to the side wall of the first limiting groove 21 . The first spring 42 makes the first limiting block 41 always have a tendency to move away from the web of the clamping plate 1 .

[0027] When the clamping plate 1 is clamped to the door leaf, the clamping plate 1 moves toward the door leaf, and the door leaf pushes the first limit block 41 to move toward the end of the first limit groove 21 with a deeper depth, so that the clamping plate 1 can be smoothly clamped to the door leaf. Under the action of the spring, the clamping plate 1 always has a tendency to move toward the end of the first limit groove 21 with a shallower depth, and the first limit block 41 always keeps one side in contact with the bottom wall of the first limit groove 21 and the other side in contact with the door leaf. When the clamping plate 1 has a tendency to move away from the door leaf, the first limit block 41 clamps the clamping plate 1 on the door leaf, thereby preventing the clamping plate 1 from moving away from the door leaf.

[0028] Reference Figure 1 and Figure 3The second limiting unit 5 includes a second limiting block 51 and a second spring 52. Two second limiting grooves 22 are provided on the inner wall of the wing plate on the same side of the clamping plate 1. The bottom walls of the two second limiting grooves 22 are inclined so that the cross-sectional shapes of the two second limiting grooves 22 are both right-angled trapezoids. The two second limiting grooves 22 with deep depths are close to each other, and the two second limiting grooves 22 with shallow depths are far away from each other. The second limiting block 51 is also a wedge-shaped block. The second limiting block 51 is provided in the two second limiting grooves 22. One side of the second limiting block 51 is in contact with the bottom wall of the second limiting groove 22, and the other side of the second limiting block 51 is parallel to the plane of the wing plate of the clamping plate 1. The second spring 52 is also provided in the two second limiting grooves 22. One end of the second spring 52 is connected to the second limiting block 51, and the other end of the second limiting block 51 is connected to the side wall of the second limiting groove 22. The second spring 52 makes the second limiting block 51 always have a tendency to move toward the end of the second limiting groove 22 with a shallow depth.

[0029] After the clamping plate 1 is clamped on the door leaf, since the two second limiting grooves 22 with deep sides are close to each other and the shallow sides are far away from each other, when the clamping plate 1 moves along the length direction of the door leaf on the door leaf, it will drive one of the second limiting blocks 51 to move toward the shallow end of the corresponding second limiting groove 22, thereby hindering the movement of the clamping plate 1; the combination of the second limiting blocks 51 in the two second limiting grooves 22 makes it impossible for the clamping plate 1 to move along the length direction of the door leaf.

[0030] Reference Figure 2 and Figure 3 The first limiting unit 4 and the second limiting unit 5 are both provided on the inner walls of the two side wing plates of the clamping plate 1. The first limiting unit 4 and the second limiting unit 5 on the two side wing plates of the clamping plate 1 are used to fix the clamping plate 1 together, thereby improving the clamping effect of the clamping plate 1 on the door leaf.

[0031] Reference Figure 2 and Figure 3 Slide blocks (not shown in the drawings) are provided on both side walls of the first limit block 41 and the second limit block 51, and slide grooves 23 adapted to the slide blocks are provided on both side walls of the first limit groove 21 and the second limit groove 22. The slide grooves 23 on the side walls of the first limit groove 21 are parallel to the bottom wall of the first limit groove 21, and the slide grooves 23 on the side walls of the second limit groove 22 are parallel to the bottom wall of the second limit groove 22. Through the cooperation between the slide block and the slide groove 23, the first limit block 41 can only move in the first limit groove 21, and the second limit block 51 can only move in the second limit groove 22, so as to prevent the first limit block 41 and the second limit block 51 from being separated from the clamping plate 1, and one side of the first limit block 41 is always in contact with the bottom wall of the first limit groove 21, and one side of the second limit block 51 is always in contact with the bottom wall of the second limit groove 22.

[0032] Reference Figure 2 and Figure 3 Electromagnets 6 are embedded on the side walls of the first limiting groove 21 and the second limiting groove 22 where the depth is deep, and the first limiting block 41 and the second limiting block 51 are both made of magnetic conductive metal. When it is necessary to remove the clamping plate 1 from the door leaf, multiple electromagnets 6 are activated, and the electromagnets 6 adsorb the first limiting block 41 and the second limiting block 51, so that the first limiting block 41 moves toward the end of the first limiting groove 21 where the depth is deep, and the second limiting block 51 moves toward the end of the second limiting groove 22 where the depth is deep, thereby separating the first limiting block 41 and the second limiting block 51 from the clamping plate 1, making it easier to remove the clamping plate 1 from the door leaf.

[0033] Reference Figure 1 The mounting frame 2 is an L-shaped plate body. The vertical section of the mounting frame 2 is detachably mounted on the clamping plate 1 by bolts, and the horizontal section of the mounting frame 2 extends horizontally toward the door leaf. The fixing assembly 3 includes a fixing plate 31. A receiving groove 32 for receiving the door leaf handle is provided at the top of the horizontal section of the mounting frame 2. The shape of the fixing plate 31 matches the shape of the handle. The fixing plate 31 is rotatably arranged on the mounting frame 2 and is located above the opening of the receiving groove 32. When fixing the handle, the handle is placed in the receiving groove 32. After the position of the handle is determined, the fixing plate 31 is rotated to cover the handle, and the handle is pressed and fixed in the receiving groove 32 by tightening the bolts to achieve the fixing of the handle.

[0034] The implementation principle of a positioning device for the outer handle of a civil defense door leaf in an embodiment of the present application is as follows: when the door leaf handle is installed to a specified position on the door leaf, the clamping plate 1 is clamped at a position on the door leaf corresponding to the handle. At this time, the clamping plate 1 is fixed to the door leaf through a limiting assembly, and then the position of the handle is aligned and installed on the mounting frame 2. The handle is fixed to the mounting frame 2 through a fixing assembly 3, thereby achieving an effect of fixing the handle; thereafter, the handle is connected to the door lock system and to the door leaf installation, and during the installation process, there is no need to manually fix the position of the handle, which facilitates the installation of the handle on the door leaf.
