Description

Technical Field

[0001] This utility model relates to the field of protective railings, and more particularly to a protective railing for civil defense projects. Background Technology

[0002] Civil defense engineering guardrails are facilities used to improve the safety of civil defense engineering projects. They are mainly installed in high-altitude or dangerous areas inside or outside the project to prevent people from falling from heights or being hit by objects.

[0003] Especially in civil defense engineering passageways or stairwells, guardrails are typically required. These guardrails usually have a narrow entrance / exit to guide orderly passage and prevent accidental falls when there are many people. However, the location of the entrance / exit is generally fixed and cannot be adjusted. In special circumstances where the entrance / exit location needs to be changed, the entire guardrail often needs to be replaced, which is time-consuming and labor-intensive. Therefore, this application document provides a type of guardrail for civil defense engineering. Utility Model Content

[0004] The purpose of this utility model is to provide a civil defense engineering protective railing that is simple to operate and easy to adjust the position of the entrance and exit.

[0005] This utility model is achieved through the following measures: A protective railing for civil defense engineering is characterized by comprising a horizontal bar set on the ground inside the passage entrance, wherein several sets of fences are set on the horizontal bar, and the several sets of fences are connected to each other to form a whole, forming a blockage of the passage entrance. If an exit needs to be left at a certain position, the fence at that position can be removed, thereby achieving the effect of adjusting the entrance according to the situation. The fence includes a rectangular frame, and several rods are set inside the rectangular frame.

[0006] When using this guardrail, it is first fixed to both sides of the passage entrance and exit with expansion bolts. When the passage entrance and exit do not need protection, several sets of the guardrail can be stored on the placement plate and the wall near the passage entrance and exit can be rotated. When protection is needed, the guardrail on the placement plate can be slid onto the horizontal bar. At the same time, the required number of guardrails can be slid according to the width of the reserved exit. Then, the guardrail can be slid to the corresponding position according to the position of the reserved exit.

[0007] Adjacent fences are connected and secured by inserting a strip plate on one side into the corresponding slot.

[0008] The specific features of this utility model also include: The upper side of the horizontal bar is provided with a T-shaped groove, and a number of sets of cooperating T-shaped sliding rods are slidably arranged in the T-shaped groove, and the fence is provided on the T-shaped sliding rods; The side of the horizontal bar is provided with several sets of locking bolts that cooperate with the T-shaped slide bar. The locking bolts are threaded into the T-shaped slide groove. The side of the T-shaped slide bar is provided with insertion holes that cooperate with the locking bolts. When the fence is slid to a suitable position, the fence is fixed by inserting the locking bolts into the insertion holes.

[0009] The horizontal bar is provided with a vertical bar one and a vertical bar two at both ends. Both vertical bar one and vertical bar two are provided with a fixing plate on their outer side facing the outside of the channel. Expansion bolts are provided on the fixing plate to fix them to the walls on both sides of the channel entrance and exit.

[0010] A placement plate is rotatably mounted on the horizontal rod near the inner side of the vertical rod. When the placement plate rotates, it can slide along the upper side of the horizontal rod, that is, it can rotate onto the horizontal rod. A groove is provided on the upper side of the placement plate. A sliding groove is provided on each of the opposite sides of the groove. A slider is provided at both ends of the T-shaped sliding rod, which slides in cooperation with the sliding groove and the slider slides in cooperation with the lower groove of the T-shaped sliding groove.

[0011] The groove has a through groove one on the side near the horizontal bar, allowing the T-shaped slider to slide through. The horizontal bar has a through groove two on the side near the vertical bar, which cooperates with the through groove one and extends to the bottom of the T-shaped slide groove. When the placement plate rotates, causing the through groove one to rotate above the through groove two, the T-shaped slider can slide through the through groove one into the through groove two, and then slide along the T-shaped slide groove. The free end of the placement plate is provided with a notch that extends into the groove and the through groove. The notch engages with the upper part of the T-shaped slide bar and the rectangular frame, meaning that the fence can slide along the T-shaped slide bar through the notch. When the passage entrance does not require protection, several sets of the fences can be stored on the placement plate. When protection is required, the fences on the placement plate are slid onto the horizontal bar. At the same time, the required number of fences can be slid according to the width of the reserved exit, and then the fences are slid to the corresponding positions according to the position of the reserved exit. A second sliding groove is provided on one end face of the upper side of the rectangular frame, and an insert plate is slidably disposed in the second sliding groove. A slot that mates with the insert plate is provided on the other end face of the upper side of the rectangular frame. Two adjacent fences are connected by inserting the insert plate into the corresponding slot.

[0012] A long slide groove is provided on the upper side of the rectangular frame, which passes through the second slide groove. A screw rod is provided on the insert plate. The upper end of the screw rod passes through the long slide groove and is provided with a handle. The lower end of the screw rod passes through the insert plate. When the fence is stored, the handle is rotated so that the screw rod is pressed against the bottom surface of the second slide groove, thereby locking and fixing the insert plate and preventing the insert plate from sliding out.

[0013] A through hole is provided on the upper side of the rectangular frame, leading to the slot. A locking rod is slidably installed through the through hole. A locking hole is provided on the insert plate to cooperate with the locking rod. When the insert plate is inserted into the slot, the lower end of the locking rod falls into the locking hole, thereby achieving a fixed connection between two adjacent fences.

[0014] A circular plate is provided at the upper end of the locking rod, and a spring is provided around the locking rod. One end of the spring is fixed to the circular plate, and the other end of the spring is fixed to the upper side of the rectangular frame. A handle is provided on the upper side of the circular plate. When the spring is engaged, the lower end of the locking rod is inserted into the locking hole. Pulling the handle can compress the spring, causing the locking rod to disengage from the locking hole, thereby locking the insert plate.

[0015] The beneficial effects of this utility model are as follows: the solution provided in this application document has a simple structure and is easy to operate. In particular, the setting of several sets of fences can reserve entrance and exit positions according to the situation. At the same time, when the fences are not needed, several sets of fences can be stored on the placement board. Then the placement board can be rotated to be close to the wall to completely open the entrance and exit of the entire passage. Attached Figure Description
