Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a quick-release guardrail for construction. Background Technology

[0002] Standard guardrails, which are widely used in construction, typically consist of a base, posts, and horizontal railings connecting the posts. The design of such guardrails emphasizes structural stability, so the base and support rods generally adopt a rigid fixed connection method. However, this traditional fixed connection structure has brought significant problems in practical application and operation and maintenance. During transportation, the utilization rate of the vehicle compartment is low, there are many gaps, and it is difficult to stack tightly. During storage, the vehicle is not stable and occupies a huge area, resulting in high logistics and storage costs.

[0003] Furthermore, due to the strong connections, specialized tools are required, and disassembly is time-consuming and labor-intensive. After recycling, the entire structure still needs to be stored or transported, and space issues remain. Therefore, while existing standard guardrails meet basic isolation and protection needs in terms of functionality, they are insufficient in terms of transportation economy, storage convenience, and installation convenience. Utility Model Content

[0004] The main purpose of this utility model is to propose a quick-release guardrail for construction, which is designed to facilitate transportation and installation.

[0005] To achieve the above objectives, the quick-release guardrail for construction proposed in this utility model includes: The base has a slot on its side for inserting a base plate. A support rod, one end of which is fixedly connected to the base plate, and the axial direction of the support rod is perpendicular to the opening direction of the insertion slot.

[0023] Standard guardrails, which are widely used in construction, typically consist of a base, posts, and horizontal railings connecting the posts. The design of such guardrails emphasizes structural stability, so the base and support rods generally adopt a rigid fixed connection method. However, this traditional fixed connection structure has brought significant problems in practical application and operation and maintenance. During transportation, the utilization rate of the vehicle compartment is low, there are many gaps, and it is difficult to stack tightly. During storage, the vehicle is not stable and occupies a huge area, resulting in high logistics and storage costs.

[0024] Furthermore, due to the strong connections, specialized tools are required, and disassembly is time-consuming and labor-intensive. After recycling, the entire structure still needs to be stored or transported, and space issues remain. Therefore, while existing standard guardrails meet basic isolation and protection needs in terms of functionality, they are insufficient in terms of transportation economy, storage convenience, and installation convenience.

[0025] This utility model proposes a quick-release guardrail for construction.

[0026] Please see Figures 1 to 5In one embodiment of the present invention, the quick-release guardrail for construction includes a base 1, and the side of the base 1 is provided with an insertion groove 11 for inserting a base plate 2. Support rod 3, one end of which is fixedly connected to the base plate 2, and the axial direction of the support rod 3 is perpendicular to the opening direction of the insertion groove 11. The support surface 12 of the base 1 has a sliding notch 121 for inserting the support rod 3. The support surface 12 is provided with sliding platforms 122 on both sides, and the sliding platform 122 is provided with a slide rail 1221, and the extension direction of the slide rail 1221 is parallel to the axial direction of the support rod 3. Locking component 4 includes locking pin 41 and lifting rod 42. Both ends of the lifting rod 42 are slidably connected to the slide rails 1221 on opposite sides. The lifting rod 42 and the locking pin 41 are fixedly connected. The lifting rod 42 drives the locking pin 41 to move, so as to lock and unlock the base plate 2. The support surface 12 is provided with a mounting hole 123, and the mounting hole 123 is connected to the insertion groove 11. The locking pin 41 is slidably connected to the mounting hole 123. When the base plate 2 is in the locked state, the locking pin 41 is partially inserted into the limiting hole 21 provided in the base plate 2 to restrict the movement of the base plate 2. The support surface 12 is recessed to form a lifting groove 124, and the lifting groove 124 and the lifting rod 42 are correspondingly arranged to lift the lifting rod 42. The technical solution of this utility model achieves locking and unlocking of the base plate 2 by using the locking component 4. The support rod 3 and the base plate 2 are inserted into each other through the sliding notch 121 and the insertion groove 11, respectively, rather than being permanently fixed. When inserted, the lifting rod 42 can be raised to drive the locking pin 41 to move. The sliding platforms 122 on both sides guide the movement of the lifting rod 42. After the base plate 2 is in place, the lifting rod 42 is lowered, and the locking pin 41 is partially inserted into the limiting hole 21 to lock the base plate 2. Under no external force, the locking pin is not easy to disengage from the limiting hole 21. When disassembly is required, the locking can be released by raising the lifting rod 42, and the base plate 2 can be pushed out at the same time to separate it from the base 1 for easy transportation. The operator can insert his feet into the lifting groove 124 to raise the lifting rod 42, improving the convenience of installation and disassembly.

[0027] It should be noted that the slide rail 1221 is provided with blocking walls at both ends to limit the movement distance of the lifting rod 42, thereby preventing the locking pin 41 from disengaging from the mounting hole 123. During installation, there is no need to install the limiting pin separately; it is only necessary to lift or lower the lifting rod 42.

[0028] like Figure 1 As shown, when inserting or pushing the base plate 2 into the insertion slot 11, it is necessary to fix the base plate 2 or the base 1. Otherwise, it may be difficult to disengage or insert due to friction. The operator can control the movement of the locking pin 41 by stepping on the base 1 and lifting the lifting rod 42 with the toes. At the same time, the heel fixes the base 1. At this time, the operator can insert or push the support rod 3 by hand to drive the base 1 to insert or disengage from the insertion slot 11. The installation and disassembly can be completed by one person, and one person can control the movement of the base plate 2 and the movement of the locking pin 41 at the same time, which is convenient for installation and disassembly.

[0029] It should be noted that a lifting groove 124 for inserting toes is provided between the lifting rod 42 and the base 1.

[0030] In some embodiments, the lifting rod 42 is abutted by the blocking wall, leaving a gap between the lifting rod 42 and the base 1.

[0031] Optionally, the axial direction of the locking pin 41 is perpendicular to the axial direction of the lifting rod 42; When the base plate 2 is in the locked state, the lifting rod 42 abuts against the support surface 12.

[0032] like Figure 2 As shown, the locking pin 41 only needs to be partially inserted into the limiting hole 21 to complete the locking. If it is inserted too much, it needs to be moved a long distance to unlock. Therefore, the lifting rod 42 abuts against the support surface 12 to prevent the locking pin 41 from going too deep into the limiting hole 21.

[0033] Furthermore, during transportation, the lifting rod 42 can also abut against the support surface 12 to prevent damage.

[0034] like Figure 3 As shown, the lifting rod 42 is sleeved with a lifting sleeve 421, the lifting sleeve 421 is rotatably connected to the lifting rod 42, and the lifting sleeve 421 is correspondingly arranged with the lifting groove 124; There are two locking pins 41, which are located on opposite sides of the lifting sleeve 421, and the base plate 2 has two corresponding limiting holes 21.

[0035] It is understood that the lifting rod 42 is rotatably connected to the lifting sleeve 421. When the lifting rod 42 is lifted on the foot, rolling friction occurs between the lifting sleeve 421 and the rubber part instead of sliding friction, thereby reducing resistance.

[0036] Furthermore, the lifting sleeve 421 is also easy to hold by hand, and the base 1 can be moved by holding the lifting sleeve 421.

[0037] It is understood that the lifting sleeve 421 is provided with locking pins 41 on both sides to ensure the stability of the lifting and avoid tilting and jamming.

[0038] Optionally, a guide ramp 111 is provided at the opening of the insertion slot 11.

[0039] It is understood that the guide ramp 111 allows the base plate 2 to be inserted into the insertion slot 11 without precise alignment, thus improving ease of operation.

[0040] It is understandable that, in order to prevent the base plate 2 from shaking or tilting within the insertion groove 11, the insertion groove 11 is fitted with the base plate 2 with a clearance.

[0041] Optionally, the sidewall of the lifting groove 124 is connected to the outside of the base 1, and the bottom of the lifting groove 124 is provided with a stepping boss 1241. The projection of the lifting rod 42 at the bottom of the lifting groove 124 is located on the side of the stepping boss 1241 away from the outside.

[0042] like Figure 4 As shown, the step-mounted protrusion 1241 provides a rotation fulcrum for the foot. When lifting, the foot uses the step-mounted protrusion 1241 as a rigid support point, and the toes or forefoot lift the lifting rod 42, providing a larger lifting angle and requiring less effort.

[0043] In some embodiments, the cross-section of the lifting boss is arc-shaped to facilitate foot rotation.

[0044] like Figure 4 As shown, the lifting groove 124 is provided with a stepping inclined surface 1242, which is located on the side of the stepping protrusion 1241 near the outside.

[0045] Understandably, when the foot rotates around the stepping protrusion 1241, the heel will press down, and the stepping inclined surface 1242 provides space for the heel to press down, so as to complete the installation and disassembly by stepping on the base 1 with the foot.

[0046] like Figure 5 As shown, the quick-release guardrail for construction also includes a guardrail plate 5, and the guardrail plate 5 has plug-in blocks 51 on its opposite side walls along the length direction; The support rod 3 is connected to a connecting sleeve 6. The side wall of the connecting sleeve 6 is provided with an abutment plate 61. The abutment plate 61 has an insertion hole 611 for inserting the insertion block 51. The extension direction of the insertion hole 611 is parallel to the axis of the support rod 3, and the insertion block 51 partially abuts against the side of the abutment plate 61 away from the base 1.

[0047] It is understood that installing the guardrail plate 5 only requires aligning the two side plug blocks 51 with the plug holes 611 on the connecting sleeve 6 of the support rod 3 and inserting it vertically downward in a direction parallel to the axis of the support rod 3 to complete the installation; disassembly is achieved by simply lifting it out, realizing tool-free operation and making the operation simple.

[0048] In some embodiments, the guardrail panel 5 and the connecting rod are fixedly connected.

[0049] Optionally, the support rod 3 has an annular groove 31 formed in the concave part of its body; The connecting sleeve 6 is fitted into the annular groove 31, and the connecting sleeve 6 rotates around the support rod 3 to change the position of the guardrail 5.

[0050] It should be noted that the base plate 2 is fixedly connected to the support rod 3, and the base plate 2 cannot rotate relative to the base 1. Therefore, if the support rod 3 is fixedly connected to the guardrail 5, the guardrail 5 needs to be lifted and rotated by a certain angle as a whole when changing its position.

[0051] It is understood that the connecting sleeve 6 is fitted onto the annular groove 31, and the connecting sleeve 6 can rotate around the support rod 3, so as to change the position of the guardrail 5 without moving the base 1, thereby improving the ease of installation.

[0052] Optionally, the support rod 3 is sleeved with a plurality of the connecting sleeves 6.

[0053] It is understood that the guardrail 5 is connected to the support rod 3 through the connecting sleeve 6. By increasing the number of connecting sleeves 6 connected to the guardrail 5, the connection firmness can be improved and the connection stability can be guaranteed.

[0054] In some embodiments, one of the support rods 3 is simultaneously connected to multiple guardrail panels 5 via multiple connecting sleeves 6.

[0055] In one embodiment, one support rod 3 is sleeved with four connecting sleeves 6, two connecting sleeves 6 are connected to the same guardrail plate 5, one support rod 3 is connected to two guardrail plates 5 at the same time, and it is understood that the angle between the two guardrail plates 5 is adjustable to improve applicability.

[0056] Optionally, a plurality of abutment plates 61 are provided on the side wall of one of the connecting sleeves 6, and the plurality of abutment plates are arranged around the axis of the connecting sleeve 6 to connect the plurality of guardrail plates 5.

[0057] It is understood that, through multiple abutment plates, one support rod 3 can simultaneously connect multiple guardrail plates 5.

[0058] In one embodiment, one of the connecting sleeves 6 has two abutment plates on its sidewall, and the two abutment plates are respectively located on opposite sides of the connecting sleeve 6.

[0059] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
