Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction protection technology, and in particular relates to a protective railing that is easy to install. Background Technology
[0002] Safety railings in building construction are various structures and measures installed to ensure safety during the construction process, prevent accidents, and protect the safety of personnel and equipment. These safety railings are widely used in the field of building construction.
[0003] To facilitate transportation and carrying, guardrails are mostly designed as modular structures, formed by assembling multiple parts together. Current guardrails utilize numerous threaded fastening structures during assembly. The assembly process requires positioning each part before securing adjacent parts with these threads, resulting in low efficiency. Therefore, further research is needed to improve the assembly efficiency of guardrails. Utility Model Content
[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a guardrail that is easy to install, has simple assembly operation, high assembly efficiency, and stable structure.
[0005] In view of this, the present invention provides a protective fence that is easy to install, comprising:
[0006] The base has two sets of female components on it.
[0007] The main column has a movable column at its top. One end of the movable column is rotatably connected to the main column, and the end of the movable column away from the main column can swing to a position perpendicular to the main column.
[0008] The secondary column has a first connector at its top, which can be connected to the end of the movable column away from the main column.
[0009] Two sets of sub-components are respectively set on the side walls of the main column and the secondary column. The sub-components can rotate relative to the main column or the secondary column. The sub-components can be axially fitted onto the parent component. At this time, the rotation of the sub-components relative to the parent component can restrict the axial movement of both.
[0010] The locking component can be connected to two sets of sub-components simultaneously to restrict the rotation of the two sets of sub-components relative to the main column or the secondary column.
[0011] In this technical solution, by cooperating with the main column, movable column, secondary column and first connecting piece, the assembly of the upper part of the guardrail is completed by installing the first connecting piece between the movable column and the secondary column. For the assembly of the lower part of the guardrail, by fitting two sets of sub-parts into two sets of mother parts respectively, and then rotating the two sets of sub-parts respectively, the upper part of the guardrail is fixed on the base. Finally, the rotation of the two sets of sub-parts is restricted by the locking piece, so that the upper part of the guardrail is stably fixed on the base.
[0012] In the above technical solution, furthermore, when the two sets of sub-components are connected to the two sets of parent components respectively, the bottom surfaces of the main column and the secondary column can simultaneously contact the base.
[0013] In the above technical solution, furthermore, the end of the movable column away from the main column can swing to a state parallel to the main column.
[0014] In the above technical solution, the first connecting member further includes a first threaded hole, a first through hole, and a threaded fastener. The first threaded hole is located at the end of the movable column away from the main column, the first through hole is located on the top side wall of the secondary column, and the threaded end of the threaded fastener passes through the first through hole and is threadedly connected to the first threaded hole.
[0015] In the above technical solution, further, the mother component includes a fixed post and multiple connecting blocks. The multiple connecting blocks are spaced apart circumferentially on the side wall of the fixed post. Each of the lower part of the side wall of the multiple connecting blocks has a slot along the same circumferential direction. The daughter component includes a fixed sleeve and multiple movable blocks. The multiple movable blocks are spaced apart circumferentially on the inner wall of the fixed sleeve. Each of the lower part of the side wall of the multiple movable blocks has a locking block along the same circumferential direction. The movable blocks and locking blocks can simultaneously pass between two adjacent connecting blocks, and the locking blocks can engage in the slots.
[0016] In the above technical solution, the sub-component further includes an installation section, which is rotatably connected to the main column or the secondary column. When the installation section rotates, it can drive the fixed sleeve to rotate. A second through hole is provided on the side wall of one set of installation sections, and a second threaded hole is provided on the side wall of another set of installation sections. The locking member is a long rod with a threaded structure at one end. The threaded end of the locking member passes through the second through hole and is threadedly connected to the second threaded hole.
[0017] The beneficial effects of this utility model are:
[0018] 1. Through the swing-type design of the movable column and the main column, only one point of connection and fixation between the end of the movable column and the secondary column is required when assembling the upper part of the guardrail. In addition, through the rotation and snap-fit design of two sets of sub-components and two sets of mother components, a quick installation method of "one set and one rotation" is realized. Finally, the rotation of the two sets of sub-components is constrained by the locking component to ensure a stable connection between the upper and lower parts of the guardrail. Compared with the traditional multi-step operation of positioning and then tightening, and the installation of more threaded structures, the guardrail of this utility model has high assembly efficiency and good structural stability.
[0019] 2. The mechanical interlock is formed by rotating and snapping the sub-components with the mother component to prevent axial displacement of both. The locking component further restricts the rotation of both sets of sub-components. This double locking ensures reliable connection of the guardrail.
[0020] 3. The movable column can swing relative to the main column until the two are parallel, which can save transportation space when the guardrail is in the disassembled state and reduce transportation costs. Attached Figure Description

It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0035] like Figures 1-9 As shown, this embodiment provides a guardrail that is easy to install, including: a base 1, two sets of female parts 2, a main column 3, a secondary column 5, two sets of female parts 7, and a locking part 8;
[0036] Overall structure
[0037] In this embodiment, the base 1 can be stably placed on the ground of the construction site. Please refer to [link / reference]. Figure 3 and Figure 4Two sets of female parts 2 are provided on the upper surface of the base 1;
[0038] Please see Figure 1 The top of the main column 3 is provided with a movable column 4. One end of the movable column 4 is rotatably connected to the main column 3, so that the end of the movable column 4 away from the main column 3 can swing with the other end as the fulcrum.
[0039] Please see Figure 2 The secondary column 5 is distributed parallel to the main column 3 at intervals. The top of the secondary column 5 is provided with a first connector 6, which can be connected to the end of the movable column 4 away from the main column 3.
[0040] Two sets of sub-components 7 are respectively set on the side walls of the main column 3 and the secondary column 5. The sub-components 7 can rotate relative to the main column 3 or the secondary column 5. The sub-components 7 can be sleeved on the mother component 2 along the axial direction. At this time, the rotation of the sub-components 7 relative to the mother component 2 can restrict the axial movement of both.
[0041] The locking component 8 can be connected to two sets of sub-components 7 simultaneously, thereby restricting the rotation of the two sets of sub-components 7 relative to the main column 3 or the secondary column 5.
[0042] In addition, please see Figure 1 and Figure 2 When the locking element 8 is connected to both sets of sub-parts 7 at the same time, from the perspective of the overall guardrail structure, the locking element 8 can be regarded as a blocking structure in the guardrail.
[0043] Structure and fit of each component
[0044] 1. Fit between main column 3 and movable column 4: One end of movable column 4 is connected to the top side wall of main column 3 via a pin. Please refer to [link / reference]. Figure 3 and Figure 4 When assembling the guardrail, the end of the movable post 4 furthest from the main post 3 can swing to a position perpendicular to the main post 3. At this time, the movable post 4 can be connected and fixed to the secondary post 5 through the first connecting piece 6. Preferably, when the movable post 4 swings to a position perpendicular to the main post 3, the end surface of the movable post 4 near the main post 3 can contact the side wall of the main post 3. That is, the position perpendicular to the main post 3 is the endpoint of the upward swing of the movable post 4. This eliminates the need for separate positioning between the movable post 4 and the secondary post 5. Please refer to [link to relevant documentation]. Figure 5 When the guardrail is disassembled, the end of the movable column 4 that is away from the main column 3 can swing to a parallel state with the main column 3, which facilitates the transportation and storage of the main column 3 and the movable column 4.
[0045] 2. The fit between movable column 4 and secondary column 5: Please refer to... Figure 4The first connecting member 6 includes a first threaded hole 601, a first through hole 602, and a threaded fastener 603. The first threaded hole 601 is provided on the end face of the movable column 4 away from the main column 3, and the first through hole 602 is provided on the top side wall of the secondary column 5. The first through hole 602 penetrates the two opposite side walls of the secondary column 5. The first threaded hole 601 is positioned opposite the first through hole 602 when the movable column 4 is perpendicular to the main column 3. The threaded fastener 603 can be a screw or bolt from the prior art. The threaded fastener 603 has a threaded end and a fixed end. The threaded end of the threaded fastener 603 is adapted to the first threaded hole 601, and the threaded end of the threaded fastener 603 can pass through the first through hole 602, while the fixed end of the threaded fastener 603 cannot pass through the first through hole 602. Please refer to [link to previous section]. Figure 2 When assembling the guardrail, the threaded end of the threaded fastener 603 is passed through the first through hole 602 and then threaded into the first threaded hole 601 to connect and fix the movable column 4 and the sub-column 5.
[0046] 3. The fit between the two sets of sub-components 7 and the main column 3 and the secondary column 5: In this embodiment, the fit between the sub-components 7 and the main column 3 is the same as the fit between the sub-components 7 and the secondary column 5. Taking the fit between the sub-components 7 and the main column 3 as an example, an extension block perpendicular to the length direction of the main column 3 is provided on the side wall of the main column 3. The sub-components 7 are distributed parallel to the main column 3. One end of the sub-components 7 is rotatably connected to the bottom surface of the extension block, and the other end of the sub-components 7 is used to fit with the mother component 2.
[0047] 4. Structure of Sub-component 7: Sub-component 7 includes mounting section 704, fixing sleeve 701, and multiple movable blocks 702. For details, please refer to [link / reference needed]. Figure 7 The mounting section 704 is fixedly connected to the fixing sleeve 701. The outer contours of the mounting section 704 and the fixing sleeve 701 shown in the figure are not identical; this is merely an example. In actual manufacturing, the mounting section 704 and the fixing sleeve 701 can be an integral structure, meaning their outer contours are the same. Please refer to [link to relevant documentation]. Figure 8 The bottom surface of the fixed sleeve 701 is provided with a cylindrical groove. Multiple movable blocks 702 are arranged at intervals along the circumference of the fixed sleeve 701 on the inner wall of the fixed sleeve 701. The lower part of the side wall of the multiple movable blocks 702 is provided with a locking block 703 along the same circumferential direction. The number of movable blocks 702 in the figure is three as an example. In actual manufacturing, the number of movable blocks 702 can be two, four or other numbers. The locking block 703 can be provided on each movable block 702, or the locking block 703 can be provided on only a few of the movable blocks 702.
[0048] 5. Structure of Mother Component 2: Please refer to Figure 8The mother component 2 includes a fixed post 201 and multiple connecting blocks 202. The multiple connecting blocks 202 are spaced apart on the side wall of the fixed post 201 along the circumference. The lower middle part of the side wall of the multiple connecting blocks 202 is provided with a slot 203 along the same circumferential direction. The lower middle part here can be understood as the slot 203 not penetrating the top surface of the connecting block 202 in the axial direction.
[0049] 6. Fitting between sub-component 7 and parent component 2: The bottom of the fixed sleeve 701 can be axially fitted onto the outside of the fixed post 201 and connecting block 202, while the movable block 702 and the locking block 703 can simultaneously pass between two adjacent connecting blocks 202. The contour of the locking block 703 matches the contour of the slot 203. The fixed sleeve 701 can rotate in the forward circumferential direction to engage the locking block 703 into the slot 203, and rotate in the reverse circumferential direction to disengage the locking block 703 from the slot 203. Here, forward and reverse are relative. Figure 9 In the orientation sequence, counterclockwise is the positive direction, and clockwise is the negative direction.
[0050] 7. The fit between the female part 2 and the base 1: In this embodiment, the female part 2 is fixed on the upper surface of the base 1. The female part 2 can be fixed to the base 1 by welding or by threading. When the guardrail is disassembled, the female part 2 and the base 1 can still remain connected.
[0051] 8. The fit between the main column 3 and the secondary column 5 and the base 1: Please refer to... Figure 1 and Figure 2 When the two sets of sub-components 7 are connected to the two sets of mother components 2 respectively, the bottom surfaces of the main column 3 and the secondary column 5 can simultaneously contact the upper surface of the base 1, which can improve the overall structural stability of the guardrail.
[0052] 9. The fit between locking component 8 and the two sets of sub-components 7: Please refer to... Figure 3 and Figure 4 A second through hole 9 is provided on the side wall of one set of mounting sections 704, and a second threaded hole 10 is provided on the side wall of another set of mounting sections 704. The locking member 8 is a long rod with a threaded structure at one end. After the two sets of sub-parts 7 are rotated and engaged with the two sets of female parts 2 respectively, the second threaded hole 10 and the second through hole 9 are positioned opposite each other. At this time, the threaded end of the locking member 8 is passed through the second through hole 9 and threadedly connected to the second threaded hole 10, which can simultaneously restrict the rotation of the two sets of sub-parts 7 relative to the main column 3 or the secondary column 5.
[0053] Assembly process of guardrail
[0054] In the disassembled state, each guardrail consists of a main post 3, a movable post 4, and a set of sub-parts 7 as a single component. The threaded fastener 603 can be screwed into the first threaded hole 601 to prevent loss. The two sets of female parts 2 and the base 1 form a single component. The secondary post 5 and the set of sub-parts 7 are also single components. The locking element 8 is a single component. When assembling a guardrail:
[0055] ①The main column 3 is initially fixed to the base 1 by the cooperation of the sub-part 7 and a set of female parts 2, and the secondary column 5 is initially fixed to the base 1 by the cooperation of the sub-part 7 and a set of female parts 2;
[0056] ② The threaded end of the locking piece 8 is passed through the second through hole 9 and then threadedly connected to the second threaded hole 10, so that the main column 3 and the auxiliary column 5 are stably fixed on the base 1.
[0057] ③ Swing the end of the movable column 4 away from the main column 3 upward to the end position, and then thread the threaded end of the threaded fastener 603 through the first through hole 602 and thread it into the first threaded hole 601.
[0058] Repeat the above steps to assemble multiple guardrails. The guardrails can be placed at intervals to meet the protection needs of the construction site.
