Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a quick-detachable safety guardrail for building construction. Background Art

[0002] Building construction includes foundation construction, main structure construction, roof construction and decoration construction, etc. The place of construction is called "building construction site" or "construction site". Safety guardrails are guardrails used to protect facilities and equipment at the building construction site. Safety guardrails are widely used in the field of building construction.

[0003] In the process of using the existing safety guardrail, a rigid protective net and a connecting frame are usually used for installation, and then the protective net and the connecting frame are connected by installing bolts, so as to protect the construction personnel when they are working. Since the protective net is rigid, its hardness cannot be stretched. Due to the different sizes of the protective net, the surface installation position is different. Since the installation point of the connecting frame is fixed, when the installation point of the protective net is different from the installation point of the connecting frame, auxiliary installation parts are required to be installed on the surface of the connecting frame, and then the protective net and the connecting frame are connected by auxiliary installation parts. Auxiliary parts such as hooks, steel ropes, etc., in this way, when disassembling the protective net, the protective net needs to be removed from the hook or steel rope first, and then the hook or steel rope is removed from the connecting frame to complete the overall disassembly of the guardrail. In this way, whether it is disassembly or installation, the workload of the staff is greatly increased, thereby wasting the time of the staff. For this reason, we propose a quick-detachable safety guardrail for construction to solve the above problems. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a quick-detachable safety guardrail for construction, which has the following beneficial effects.

[0018] 1. The utility model uses a hand crank to drive the threaded rod to rotate. Since the threads on the surface of the threaded rod and the threads in the inner cavity of the threaded sleeve are threadedly connected, the rotation of the threaded rod drives the threaded sleeve to move, and the movement of the threaded sleeve drives the connecting rod to move, and the movement of the connecting rod drives the mounting block to move to a specified position. The staff can adjust the position of the mounting block according to the installation point of the protective net, eliminating the step of connecting the protective net to the connecting frame with auxiliary parts, thereby improving the efficiency of installing or disassembling the protective net, greatly improving the work efficiency of the staff, and solving the troubles of the staff.

[0019] 2. The utility model can make the first mounting bolt rotate in its inner cavity through the mounting hole. Since the thread in the inner cavity of the mounting hole is threadedly connected with the thread on the surface of the first mounting bolt, the first mounting bolt can move up and down when it rotates. For example, when the first mounting bolt rotates forward, it moves downward. Conversely, when the first mounting bolt rotates reversely, it moves upward. When the first mounting bolt moves downward to connect with the connecting hole on the ground or the surface of the designated mounting position, since the thread in the connecting hole is threadedly connected with the thread on the surface of the first mounting bolt, the connecting frame is effectively locked and fixed, thereby completing the installation of the connecting frame.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 The utility model: a quick-detachable safety guardrail for construction, includes a connecting frame 1, both sides of the connecting frame 1 are fixedly connected with a shell 5, the bottom of the shell 5 is movably connected with a hand crank 4, the top of the hand crank 4 is fixedly connected with a threaded rod 9, and the top of the threaded rod 9 penetrates through the inner cavity of the shell 5 and is threadedly connected with a threaded sleeve 10, one side of the threaded sleeve 10 is fixedly connected with a connecting rod 13, one side of the connecting rod 13 penetrates through the outside of the shell 5 and is fixedly connected with a mounting block 8, and a protective net 6 is fixedly installed on the surface of the mounting block 8.

[0026] Through the above technical scheme, the hand crank 4 can be used to easily drive the threaded rod 9 to rotate. Since the threads on the surface of the threaded rod 9 and the threads in the inner cavity of the threaded sleeve 10 are threadedly connected, the rotation of the threaded rod 9 drives the threaded sleeve 10 to move, and the movement of the threaded sleeve 10 drives the connecting rod 13 to move, and the movement of the connecting rod 13 drives the mounting block 8 to move to the specified position. The staff can adjust the position of the mounting block 8 according to the installation point of the protective net 6, eliminating the step of connecting the protective net 6 to the connecting frame 1 with auxiliary parts, thereby improving the efficiency of installing or disassembling the protective net 6, greatly improving the work efficiency of the staff, and solving the troubles of the staff.

[0027] Specifically, the bottom of the connecting frame 1 is fixedly connected to a mounting plate 2, mounting holes are provided around the surface of the mounting plate 2, and the inner cavity of the mounting hole is threadedly connected to a first mounting bolt 3, one side of the inner cavity of the shell 5 is fixedly connected to a slide rail 12, the other side of the threaded sleeve 10 is fixedly connected to a slider 11, and the surface of the slider 11 is slidably connected to the inner cavity of the slide rail 12, the top of the inner cavity of the shell 5 is fixedly connected to a bearing, and the top of the threaded rod 9 is rotatably connected to the inner cavity of the bearing, a first screw hole 7 is provided on the surface of the mounting block 8, and second screw holes are provided on both sides of both ends of the protective net 6, the second screw hole and the first screw hole 7 are symmetrical, and the first screw hole 7 and the inner cavity of the second screw hole are threadedly connected to a second The mounting bolt 14 can allow the first mounting bolt 3 to rotate in its inner cavity through the mounting hole. Since the thread in the inner cavity of the mounting hole is threadedly connected with the thread on the surface of the first mounting bolt 3, the rotation of the first mounting bolt 3 enables itself to move up and down. For example, when the first mounting bolt 3 rotates forward, it moves downward. Conversely, when the first mounting bolt 3 rotates reversely, it moves upward. When the first mounting bolt 3 moves downward to connect with the connecting hole on the ground or the surface of the designated installation position, since the thread in the connecting hole is threadedly connected with the thread on the surface of the first mounting bolt 3, the connecting frame 1 is effectively locked and fixed, thereby completing the installation of the connecting frame 1.

[0028] The working principle of the utility model is as follows: first, the user moves the connecting frame 1 to the designated position, and then the user aligns the mounting hole on the surface of the mounting plate 2 with the connecting hole at the mounting position, and then takes out the first mounting bolt 3, inserts it into the inner cavity of the mounting hole, and uses the installation tool to twist the first mounting bolt 3 to rotate. Since the thread in the inner cavity of the mounting hole is threadedly connected with the thread on the surface of the first mounting bolt 3, the rotation of the first mounting bolt 3 enables itself to move up and down. For example, when the first mounting bolt 3 rotates forward, it moves downward, and conversely, when the first mounting bolt 3 is reversed, it moves upward. When the first mounting bolt 3 moves downward to connect with the ground or the connecting hole on the surface of the designated installation position, since the thread in the connecting hole is threadedly connected with the thread on the surface of the first mounting bolt 3, the connecting frame 1 is effectively locked and fixed, thereby completing the installation of the connecting frame 1. Conversely, when the connecting frame 1 needs to be disassembled, the user uses the installation tool The user can then rotate the hand crank 4 to remove the threaded rod 9 from the inner cavity of the threaded sleeve 10, and the threaded rod 9 can be rotated to move the threaded sleeve 10, and the movement of the threaded sleeve 10 can drive the connecting rod 13 to move, and the movement of the connecting rod 13 can drive the mounting block 8 to move to the specified position. The staff can adjust the position of the mounting block 8 according to the installation point of the protective net 6, and then the user makes the second screw holes on both sides of the protective net 6 symmetrical with the first screw holes 7, and then rotates the second mounting bolts 14 into the inner cavity of the second screw holes and the first screw holes 7, and when the threads on the surface of the second mounting bolts 14 are threadedly connected with the threads in the first screw holes 7 and the inner cavity of the second screw holes, the installation of the protective net 6 is completed. Figure 1 As shown, it is the state of the protective net 6 after installation. When the protective net 6 needs to be disassembled, the user only needs to use a tool to reverse the second mounting bolt 14 to disengage the second screw hole and the inner cavity of the first screw hole 7 to complete the disassembly of the protective net 6, thereby improving the disassembly and assembly efficiency of the staff and solving the troubles of the staff.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
