[0027] The utility model provides a steel structure handrail for a spiral staircase, which aims to solve the technical problem that the handrail is inconvenient to install in a narrow space in the prior art;

[0028] The utility model provides a technical solution:

[0029] First, see Figure 1-Figure 5 A steel structure handrail for a spiral staircase includes a guardrail plate 1 and a handrail body 2. The guardrail plate 1 is fixedly connected to the outer side of the pedal of the spiral staircase. The guardrail plate 1 and the handrail body 2 are both designed in a spiral structure, which is more suitable for the spiral staircase body. The handrail body 2 includes an upper handrail 202 and a lower handrail 203. By splicing the upper handrail 202 and the lower handrail 203, the handrail body 2 is designed in a spiral. The upper handrail 202 and the lower handrail 203 are respectively provided with a plug-in slot 1 and a plug-in slot 2 at both ends. The plug-in slot 1 is adapted to be installed with the plug-in slot 2. The plug-in slot 1 is placed against the plug-in slot 2 so that the upper handrail 202 and the lower handrail are connected. 203 is fixedly connected, a fixing buckle 2021 is connected to the side of the plug-in slot one close to the plug-in slot two, and the fixing buckle 2021 is designed in an arrow structure. A triangular slot is opened on the side of the plug-in slot two close to the plug-in slot one and corresponding to the position of the fixing buckle 2021. Press the plug-in slot one of the upper armrest 202 against the plug-in slot two of the lower armrest 203. At this time, due to the arrow design of the fixing buckle 2021, the fixing buckle 2021 is inserted into the triangular slot, and at the same time, the side of the fixing buckle 2021 away from the triangular slot is stuck in the triangular slot, so that the upper armrest 202 is fixedly connected with the lower armrest 203.

[0030] For further information, see Figure 1-Figure 4, multiple groups of guardrail rods 3 are installed between the guardrail plate 1 and the handrail body 2, and the guardrail rods 3 support the handrail body 2 on one side of the spiral staircase body to increase the safety of the spiral staircase. Multiple groups of fixing grooves 201 are equidistantly arranged on the surface of the handrail body 2, and the fixing grooves 201 are used to fix and connect multiple groups of guardrail rods 3 and the handrail body 2. Fixed grooves 101 are equidistantly arranged inside the guardrail plate 1 and at positions corresponding to the fixing grooves 201, so as to facilitate the installation of the guardrail rod 3. Triangular blocks are connected to both sides of the fixing grooves 1 201 and 101, and both ends of the guardrail rod 3 are embedded in the fixing grooves 1 201 and 101 through the triangular blocks. Both ends of the guardrail rod 3 are connected to fixed card blocks 301, and a card slot is arranged inside the fixed card block 301. Triangular fixing blocks 302 are slidably connected to both ends of the card slot. A spring is connected between the corner fixing blocks 302, and the triangular fixing blocks 302 are adapted and installed with the fixing groove 1 201 and the fixing groove 2 101. First, the fixing block 301 at one end of the guardrail rod 3 is inserted into the inside of the fixing groove 2 101. At this time, the spring is compressed, and the triangular fixing block 302 enters the slot. When the fixing block 301 enters the inside of the fixing groove 2 101 and is located at the lower side of the triangular block, the triangular fixing blocks 302 on both sides pop out due to the resilience of the spring. At this time, one side of the triangular fixing block 302 fits with one side of the triangular block, and the fixing block 301 is stuck in the inside of the fixing groove 1 201 to fix the guardrail rod 3 on the guardrail plate 1. Then the user presses the fixing groove 1 201 on one side of the handrail body 2 against the handrail body 2 to fix the handrail body 2 on the guardrail rod 3, so that the guardrail plate 1 is fixedly connected to the handrail body 2.

[0031] Finally, see Figure 1 , Figure 2 and Figure 5A reinforcing diagonal rod 4 is installed between every two groups of guardrails 3. The reinforcing diagonal rod 4 enhances the load-bearing capacity and stability between the guardrails 3, avoids shaking and tilting between multiple groups of guardrails 3, and prevents users from falling from a high altitude when going up and down stairs. Both ends of the reinforcing diagonal rod 4 are connected with plug-in blocks, and plug-in grooves are provided on the surfaces of multiple groups of guardrails 3 and at positions corresponding to the reinforcing diagonal rods 4. The plug-in blocks and the plug-in grooves are adapted for installation. The plug-in blocks and the plug-in grooves are both T-shaped structural designs. When installing, the user inserts the plug-in blocks at both ends of the reinforcing diagonal rod 4 into the interior of the plug-in grooves, so that the reinforcing diagonal rod 4 is connected to the guardrails 3 at both ends. The initial connection and fixation are carried out. A fixing block 5 is threadedly connected to the surface of the guardrail rod 3 at the position corresponding to the plug-in slot. The fixing block 5 is designed in a T-shaped structure. One side of the fixing block 5 is embedded in the plug-in slot. After the two ends of the reinforcing diagonal rod 4 are inserted into the plug-in slot, since the fixing block 5 is a T-shaped structure, the user inserts the protruding end of the fixing block 5 into the plug-in slot. At this time, one side of the fixing block 5 is against the plug-in block. Then the user fixes the fixing block 5 and the guardrail rod 3 with bolts, and fixes the plug-in block inside the guardrail rod 3 through the fixing block 5 to prevent the plug-in block from falling off from the plug-in slot due to external impact or vibration.

[0032] The working process of the utility model is as follows: when using the steel structure handrail for spiral staircase, the user inserts the fixing block 301 at one end of the guardrail rod 3 into the inside of the fixing groove 2 101. When the fixing block 301 enters the inside of the fixing groove 2 101 and is located at the lower side of the triangular block, the triangular fixing blocks 302 on both sides pop out due to the rebound force of the spring, and the fixing block 301 is stuck in the inside of the fixing groove 1 201. Then the user presses the fixing groove 1 201 on one side of the lower handrail 203 against the lower handrail 203 to fix the lower handrail 203 on the guardrail rod 3, and then the user puts the upper handrail 203 on the guardrail rod 3. The first plug-in slot of the hand 202 is pressed against the second plug-in slot of the lower handrail 203. At this time, the fixing buckle 2021 is inserted into the triangular slot, and the side of the fixing buckle 2021 away from the triangular slot is stuck in the triangular slot, so that the upper handrail 202 is fixedly connected to the lower handrail 203. At the same time, the fixing block 301 enters the fixing slot 1 201 on one side of the upper handrail 202. Then the user inserts the plug-in blocks at both ends of the reinforcing diagonal rod 4 into the interior of the plug-in slot, and then inserts the protruding end of the fixing block 5 into the interior of the plug-in slot. Then the user fixes the fixing block 5 to the guardrail rod 3 with bolts.

[0033] The whole operation process is simple and convenient. Compared with the existing handrails for spiral staircases, the utility model can quickly and conveniently fix and connect the handrail to the spiral staircase through the design of the fixed clamping block.
