Description

Technical Field

[0001] This utility model relates to the technical field of guardrail devices, specifically an indoor guardrail device with an adjustable angle connector. Background Technology

[0002] Indoor railings are a fundamental component of building safety protection, widely used in stair handrails, balcony edges, corridor partitions, children's rooms, and elderly people's rooms. Their core function is to prevent people from falling and ensure safe passage. At the same time, they need to match the interior decoration style (such as modern minimalist, retro, light luxury, etc.), combining practicality and decoration.

[0003] According to the prior art (application number: 202222384215.0), the document describes that "the guardrail adjustment device includes an adjustment body, an adjustment component and a locking component. The adjustment body is provided with a first clamping part and a second clamping part to form a clamping space. The adjustment component is movably disposed in the clamping space and connected to the guardrail. The locking component is tightened or loosened by adjusting the distance between the clamping parts."

[0004] This utility model achieves single height adjustment only through the mechanical clamping of the clamping part and the locking fastener. Its adjustment dimension is limited to the vertical direction, and it relies on the tightening and loosening of bolts to complete the locking. It has problems such as cumbersome operation and poor angle adaptability, and cannot meet the installation requirements of irregular spaces such as curved balconies and stair corners. Therefore, it needs to be improved. Utility Model Content

[0007] As a further description of the above technical solution: The telescopic support column includes: a telescopic arm that slides inside the support column, and an adjusting block that is fixed to the upper end of the telescopic arm; and a fixing hole, which has two sets and passes through the base for connecting to the ground-fixed guardrail.

[0008] As a further description of the above technical solution: The angle connector includes: a locking element, arranged inside the adjusting block 1, with a slot at the bottom and slidably connected to the adjusting block 1; a sliding block 1, provided in two sets, one end with a square groove sliding in the rotation slot of the adjusting block 1, and the other end having a connecting hole 1; a spring 1, arranged inside the adjusting block 1, one end connected to the locking element and the other end connected to the adjusting block 1; and a bolt 1, passing through the connecting hole 1 and threadedly connected to a nut 1.

[0009] As a further description of the above technical solution: The bottom slot of the locking component abuts against a square groove in the sliding block.

[0010] As a further description of the above technical solution: The rotating connector includes: two sets of sliding blocks, one end of which slides in the rotating groove; and a connecting hole, which is opened at the other end of the sliding block and is penetrated by a bolt, the bolt being threadedly connected to a nut.

[0011] As a further description of the above technical solution: Both ends of the sliding block 1 and the sliding block 2 are engaged in the square grooves opened on one side of the fixed railing at both ends.

By using the locking part of the angle connector and the sliding block to elastically engage, and the sliding block of the rotating connector to slide and adjust, the angle of the guardrail can be adjusted in both vertical and horizontal planes through the cooperation of the two nodes. This makes it suitable for irregular spaces such as curved balconies and stair corners, solving the problem that traditional guardrails are difficult to adapt to complex installation environments.

[0014] 2. Vertical length adjustment is achieved by sliding the telescopic arm of the telescopic support column, and height fine-tuning is achieved by sliding the telescopic arm of the support column and engaging the spring lock with the locking hole. The dual-support structure is adaptable to different floor heights. Combined with the grounding of the base fixing hole, the overall load-bearing capacity and stability are improved, meeting the protective load requirements of civil buildings.

[0025] In this embodiment, the telescopic arm 102 is made of Q235B steel and its length is adjusted by sliding along the axial direction of the support column 101. The fixing hole 104 is bolted to the ground to realize the length adjustment of the telescopic support column 1 and enhance the stability of the guardrail device.

[0026] Example 2: Based on Example 1, in order to further improve adjustability, an angle connector 2 and a rotation connector 3 are arranged on the telescopic support column 1; Specifically, the angle connecting member 2 includes: a locking member 202, which is arranged inside the adjusting block 201, has a slot at the bottom, and is slidably connected to the adjusting block 201; a sliding block 203, which has two sets, one end of which has a square groove and slides in the rotation groove of the adjusting block 201, and the other end has a connecting hole 205; a spring 204, which is arranged inside the adjusting block 201, with one end connected to the locking member 202 and the other end connected to the adjusting block 201; and a bolt 206, which passes through the connecting hole 205 and is threadedly connected to the nut 207.

[0027] In a preferred embodiment, the locking element 202 is made of aluminum alloy and is supported by the elastic force of the spring 204 (made of spring steel) against the square groove of the sliding block 203 (made of aluminum alloy). Lifting the locking element 202 allows the sliding block 203 to slide along the rotating groove. The bolt 206 passes through the connecting hole 205 and is fastened to the nut 207.

[0028] Specifically, the bottom slot of the locking component 202 abuts against the square groove of the slider 203.

[0029] In this embodiment, the card slot is embedded in the square groove to restrict the sliding of the slider 203, enhance the locking stability of the angle connector 2, and prevent angle deviation.

[0030] Specifically, the rotating connector 3 includes: two sets of sliding blocks 302, one end of which slides in the rotating groove 306; and a connecting hole 305, which is opened at the other end of the sliding block 302 and is penetrated by a bolt 206, which is threadedly connected to a nut 207.

[0031] With this configuration, the sliding block 302, made of aluminum alloy, slides along the rotating groove 306, and the bolt 206 passes through the connecting hole 305 and is fastened to the nut 207.

[0032] Specifically, both ends of the slider 203 and the slider 302 are engaged in the square grooves opened on one side of the fixed rail 501. The bolt 206 passes through the through holes opened at both ends of the fixed rail 501 and is threadedly connected to the nut 207.

[0033] Among them, the ends of the sliding block 203 and the sliding block 302 are embedded in the square groove for positioning, and the bolt 206 passes through the through hole and is fastened to the nut 207, connecting the telescopic support column 1 and the crossbar 5.

[0034] Example 3: Based on Example 2, in order to further improve adjustability, an adjustment support column 4 is arranged in the middle of the horizontal bar 5; Specifically, the adjustable support column 4 includes: a second support column 401, with a fixed railing 501 connected to its bottom; a second telescopic arm 402, with a fixed railing 501 connected to its top, slidably connected within the second support column 401 for adjusting the height of the railing; a first lock hole 403, which is formed on the second support column 401 and is arranged in multiple sets; and a first elastic lock 404, which is slidably disposed in a groove inside the second telescopic arm 402 and has a second spring 405 at its bottom. The first elastic lock 404 can be pressed into the first lock hole 403 to limit the position of the second support column 401 and the second telescopic arm 402.

[0035] In this embodiment, the telescopic arm 402 slides axially along the support column 401, and the spring lock 404 is engaged in the lock hole 403 by the spring force of the spring 405, thus limiting the position of the support column 401 and the telescopic arm 402.

[0036] In actual use, first place the base 103 on the working ground, then use bolts to fix it to the ground by inserting them into the fixing holes 104. Then, connect the horizontal bar 5 to the angle connector 2, inserting the connecting holes 205 into the square slots on both sides of the fixed bar 501. Then, insert the bolts 206 into the through holes and connecting holes 205 of the fixed bar 501. Then, screw the nut 207 into the bolt 206 to fix it. Next, connect the horizontal bar 5 to the rotating connector 3, inserting the connecting holes 305 into the square slots of the fixed bar 501. Then, insert the bolts 206 into the through holes and connecting holes 305 of the fixed bar 501. Then, screw the nut 207 into the bolt 206 to fix it.

[0037] When the angle needs to be adjusted: First, an upward pulling force is applied to the locking member 202. The spring 204 arranged inside the adjusting block 201 is compressed and deformed by the upward pulling force, causing the bottom slot of the locking member 202 to leave the square groove of the sliding block 203, thus releasing the restriction of the locking member 202 on the sliding block 203. This allows the sliding block 203 to slide in the rotation groove opened in the adjusting block 201, thereby realizing the angle adjustment of the guardrail. When the angle is adjusted, the pulling force on the locking member 202 is released. The spring 204 is no longer under tension and automatically rebounds, pushing the locking member 202 to reset. The bottom slot of the locking member 202 abuts against the square groove of the sliding block 203, restricting the sliding of the sliding block 203 in the adjusting block 201.

[0038] When height adjustment is required: First, apply pressure to the spring lock 404. The spring lock 404 compresses the spring 405, causing the spring 405 to deform. The spring lock 404 slides into the lock hole 403, releasing the restriction of the telescopic arm 402 within the support column 401, allowing the telescopic arm 402 to slide within the support column 401 to adjust the height. When the height is adjusted, release the pressure on the spring lock 404. The spring 405, no longer under the pressure of the spring lock 404, automatically rebounds, pushing the spring lock 404 through the lock hole 403 to reset, thus restricting the sliding of the telescopic arm 402 within the support column 401.

[0039] This utility model achieves multi-angle adaptation of vertical and horizontal planes through a dual-node adjustable structure to meet the needs of irregular spaces such as stair corners. It improves the height adjustment accuracy and simplifies operation by using a dual-support adjustment system combined with the automatic positioning function of the elastic lock. The composite connection method of modular slots and bolts through enhances the structural stability compared with the single clamping and fixing of the existing technology, effectively solving the problem of insufficient installation adaptability of traditional guardrails in complex scenarios.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
