[0027] The following refers to Figs. 1-3 A quick splicing civil defense door is described in detail with a specific embodiment.It is understood that the following description is only illustrative, not a specific limitation on the utility model.

[0028] As Figs. 1-3 Indicated, a quick splicing civil defense door, comprising a door frame 100 and a civil defense door body 110 hinged on the door frame 100, the civil defense door body 110 is divided into three parts of first door body 111, second door body 112 and third door body 113, wherein the first door body 111 and the third door body 113 are connected with the door frame 100 by hinged mode.This hinged design allows the door body to rotate around the hinge, so as to realize the function of opening and closing.At the same time, the second door body 112 is designed to be detachably connected with the first door body 111 and the third door body 113, connecting the second door body 112 with the first door body 111 and the third door body 113 together can form a complete civil defense door.

[0029] By dividing the civil air defense door into three smaller parts, the volume and weight of each part are effectively controlled, making it easier to carry and transport, which greatly improves the applicability of the civil air defense door in complex environments, especially in situations that require frequent movement or transfer; Because of the use of detachable connection method, the installation personnel can more quickly assemble the door bodies together to form a complete civil air defense door, which not only saves the installation time, but also reduces the installation difficulty and improves the work efficiency; When a door body fails or needs maintenance, it can be disassembled for repair or replacement without disassembling the entire civil air defense door, which not only reduces the maintenance cost, but also prolongs the service life of the civil air defense door.

[0030] Further, the first door body 111 and the second door body 112 are provided with a clamping groove 120, and the second door body 112 is provided with a first clamping rod 1123 corresponding to the clamping groove 120 of the first door body 111 and a second clamping rod 1124 corresponding to the clamping groove 120 of the third door body 113. By accurately aligning and inserting the clamping groove 120, the first clamping rod 1123 and the second clamping rod 1124 can firmly connect the first door body 111, the second door body 112 and the third door body 113 together; The second door body 112 is provided with a control mechanism which can control the movement of the first clamping rod 1123 and the second clamping rod 1124 by mechanical means. When the door body needs to be connected or disassembled, the control mechanism drives the clamping rod to enter or move out of the clamping groove 120, so as to realize the quick connection and separation between the door bodies.

[0031] Further, the second door body 112 is formed with an installation cavity, and the end face of the second door body 112 close to the first door body 111 and the third door body 113 is provided with a through groove 130 connected with the installation cavity, and the clamping groove 120 is provided on the end face of the first door body 111 and the third door body 113 close to the second door body 112. The clamping rod is arranged in the installation cavity and can slide in the installation cavity, and the control mechanism can control the sliding of the clamping rod, so that the clamping rod enters the clamping groove 120 of the first door body 111 and the third door body 113 through the through groove 130; The clamping rod is arranged in the installation cavity in the second door body 112, which avoids the exposure of external mechanical structure by arranging the clamping rod and the control mechanism in the installation cavity, so that the civil air defense door is more neat and beautiful; The design of the installation cavity enables the clamping rod and the control mechanism to be arranged more compactly in the second door body 112, thereby reducing the overall volume and weight of the civil air defense door, which is conducive to improving the carrying and transportation efficiency of the civil air defense door, and also provides more space for the arrangement of other components; Hiding the clamping rod and the control mechanism in the installation cavity can effectively prevent external interference and damage, prolonging the service life of these components.

[0032] Further, the control mechanism described above is also arranged in the installation chamber, compared with the control mechanism exposed outside, arranging it in the installation chamber can make the outer appearance of the civil air defense door more neat and beautiful, such design conforms to the modern aesthetic concept, improves the overall image of the product; arranging the control mechanism in the installation chamber can make the structure of the whole door body more compact, which not only can reduce the volume of the civil air defense door, but also can improve the stability and reliability of the door body; since the control mechanism is hidden in the installation chamber, the user cannot directly touch these mechanisms when operating, thereby avoiding the safety problems caused by misoperation.

[0033] Further, the control mechanism described above includes a driving rod 1126 and a driving unit, the driving rod 1126 is divided into a first part corresponding to the first clamping rod 1123 and a second part corresponding to the second clamping rod 1124, a rotation axis is arranged in the installation chamber, the rotation axis is located between the first part and the second part, when the driving unit works, it will drive the first part and the second part of the driving rod 1126 to rotate around the rotation axis. Such rotary motion will be converted into the linear motion of the clamping rod, that is, drive the first clamping rod 1123 and the second clamping rod 1124 to enter or move out of the clamping groove 120, thereby realizing the connection or disassembly of the door body.

[0034] Further, the driving unit described above includes a mounting shaft 1125, a worm gear 1127 and a worm 1128 that mesh with each other, the axis of the mounting shaft 1125 coincides with the rotation axis and can rotate around the rotation axis, the worm gear 1127 is sleeved on the mounting shaft 1125 and fixed circumferentially with the mounting shaft 1125, the driving rod 1126 is fixedly arranged on the mounting shaft 1125, the worm 1128 is rotatably arranged in the installation chamber, the length direction of the worm 1128 is parallel to the length direction of the second door body 112, rotating the worm 1128 can drive the worm gear 1127 to rotate, the rotation of the worm gear 1127 drives the driving rod 1126 to rotate through the mounting shaft 1125; the design of such a driving unit makes it possible to control the driving rod 1126 by simply rotating the worm 1128, thereby controlling the entry or movement of the first clamping rod 1123 and the second clamping rod 1124 into or out of the clamping groove 120. This control method is simple and effective, and can greatly improve the splicing and disassembly efficiency of the civil air defense door; in addition, since the meshing of the worm gear 1127 and the worm 1128 has self-locking property, when the worm 1128 stops rotating, the worm gear 1127 and the mounting shaft 1125 will also remain at the current position, thereby ensuring the stability and reliability of the driving rod 1126 and the clamping rod, which is crucial for the safety and stability of the civil air defense door.

[0035] Further, a through hole is formed in the side wall of the second door body 112 perpendicular to the worm 1128, which is mainly used for facilitating the operation of the worm 1128; one end of the worm 1128 is designed to extend outward into the through hole, and a hexagonal head is arranged at the end of the worm 1128 located in the through hole, so that the user can insert a special tool (such as a hexagonal wrench) into the through hole from the side of the civil air defense door to connect with the hexagonal head of the worm 1128, and then rotate the worm 1128; since the through hole is located at the side of the civil air defense door, this position is relatively hidden and not easy to be touched by mistake. At the same time, the hexagonal head also needs a corresponding tool to operate, which further avoids the possibility of mistaken operation, thereby improving the safety of the civil air defense door.

[0036] Further, in the installation chamber, a first mounting plate 1121 is slidably arranged near one side of the first door body 111, and a second mounting plate 1122 is slidably arranged near one side of the third door body 113, which allows the first mounting plate 1121 and the second mounting plate 1122 to slide within the installation chamber; the number of the first clamping rod 1123 and the second clamping rod 1124 is designed to be more than two, which is to ensure that the civil air defense door has sufficient stability and firmness when spliced; the first clamping rod 1123 is mounted on the first mounting plate 1121, and the second clamping rod 1124 is mounted on the second mounting plate 1122; the drive rod 1126 is located between the first mounting plate 1121 and the second mounting plate 1122, and the rotation of the drive rod 1126 can drive the clamping rods on the first mounting plate 1121 and the second mounting plate 1122 to move synchronously; when the civil air defense door needs to be spliced, the drive rod 1126 rotates under the action of the above-mentioned driving unit, which drives the clamping rods on the first mounting plate 1121 and the second mounting plate 1122 to move to both sides at the same time, so that the first clamping rod 1123 enters the clamping groove 120 of the first door body 111, and the second clamping rod 1124 enters the clamping groove 120 of the third door body 113, thereby realizing the rapid splicing of the civil air defense door; conversely, when the civil air defense door needs to be disassembled, the drive rod 1126 reversely rotates, which drives the clamping rods to move out of the clamping grooves 120, thereby easily realizing the disassembly of the civil air defense door.

[0037] Further, the first mounting plate 1121 and the second mounting plate 1122 are provided with long strip-shaped fixing blocks 1129 near the end faces of the drive rod 1126; a slot extending in the length direction of the fixing block 1129 is formed in the side wall of the fixing block 1129; the end portions of the first part and the second part of the drive rod 1126 are provided with insertion rods (not shown in the figure) inserted into the slot; the insertion of the insertion rod into the slot forms a stable connection between the drive rod 1126 and the first mounting plate 1121 and the second mounting plate 1122, which, in combination with the self-locking characteristics of the worm wheel 1127 and the worm 1128, can ensure that the first clamping rod 1123 and the second clamping rod 1124 will not move downward due to their own gravity.

[0038] Further, positioning blocks 140 are arranged between the second door body 112 and the first door body 111 and between the second door body 112 and the third door body 113, which are designed to enable the civil air defense door to maintain high precision during installation, ensure accurate alignment and fixation between the door bodies, and greatly simplify the installation process of the civil air defense door.
