Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically a novel detachable guardrail. Background Technology

[0002] With the continuous development of the construction industry, the requirements for construction safety and work efficiency are becoming increasingly stringent and refined. At construction sites, guardrails are important facilities for ensuring personnel safety and preventing accidental falls and falling objects. Detachable guardrails are easy to install and dismantle, and construction workers can quickly adjust their position and layout according to the actual construction situation to ensure that the construction site is always in an effective protective state.

[0003] In existing technologies, multiple railings are often connected using a pin-and-slot method. This involves placing pins and slots at corresponding positions on adjacent railings, with the pins inserted into the slots to secure and connect them. However, this single-pin-and-slot connection method is vulnerable to various external forces during actual use, such as frequent vibrations from vehicles or strong impacts from accidental collisions. Under the repeated action of these forces, the contact points between the pins and slots rub against each other, causing wear. As the wear intensifies, the gap between the pins and slots widens, severely affecting the overall stability of the railing. The originally tightly connected railings become loose, causing the entire railing to sway. This swaying is particularly noticeable in windy weather. The swaying railings in the wind not only produce annoying noises and disturb the surrounding environment, but also significantly reduce their stability, failing to effectively provide protection and posing potential safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of detachable guardrail to solve the problem of wear and tear caused by the single pin-locking connection method mentioned in the background art, which is prone to wear and tear as the guardrail shakes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel detachable guardrail, including a base plate, and further including a detachable guardrail mounted on the top of the base plate, a lifting assembly mounted on the guardrail, a hollow cylinder fixedly connected to the guardrail, a pin fixedly connected to the lifting assembly, a positioning plate fixedly connected to the pin, an elastic assembly mounted on the pin, a support plate mounted on the elastic assembly, and an extension assembly mounted on the base plate. The pin and support plate are inserted into the hollow cylinder by adjusting the assembly, and the support plate is supported by the elastic assembly to contact the hollow cylinder.

[0006] In the preferred embodiment of this technical solution, four support plates are provided, and the four support plates are evenly distributed in a circular array outside the pin.

[0007] According to the preferred embodiment of this technical solution, the lifting assembly includes a threaded rod rotatably connected to the guardrail and a slider threadedly connected to the threaded rod. The rotation of the threaded rod drives the slider and the pin to move through the threaded pair.

[0008] In the preferred embodiment of this technical solution, the guardrail has a matching groove at the corresponding position of the slider, and the slider slides inside the groove.

[0009] In a preferred embodiment of this technical solution, the elastic component includes a damping block and a first spring fixedly connected between the pin and the support plate, the first spring pushing the support plate to move away from the pin.

[0010] According to the preferred embodiment of this technical solution, the extension component includes a connecting plate fixedly connected to the base plate, an extension plate rotatably connected to the base plate, a plug rod slidably connected to the base plate, a pull ring fixedly connected to the top of the plug rod, and a second spring fixedly connected between the pull ring and the base plate. The extension plate rotates to contact the ground where the base plate is installed.

[0011] In the preferred embodiment of this technical solution, the extension plate has a locking hole at the corresponding position of the insertion rod, and the insertion rod is locked inside the locking hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By using elastic components to keep the support plate in close contact with the inner wall of the hollow cylinder, the elastic extension compensates for wear caused by friction, and prevents gaps from appearing between the support plate and the hollow cylinder, thus avoiding shaking.

[0014] 2. By extending the contact area with the ground, the base plate is increased, thus increasing the friction and stability between the object and the supporting surface. The larger contact area of ​​the extension plate can effectively enhance the stability of the guardrail, reduce the risk of it tipping over due to its high center of gravity, and provide reliable protection for the safety of users.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 -5. This utility model provides an embodiment: a novel detachable guardrail, including a base plate 1, and further including a guardrail 21 detachably installed on the top of the base plate 1, a lifting assembly installed on the guardrail 21, a hollow cylinder 31 fixedly connected to the guardrail 21, a pin 32 fixedly connected to the lifting assembly, a positioning plate 33 fixedly connected to the pin 32, an elastic component installed on the pin 32, a support plate 34 installed on the elastic component, and an extension assembly installed on the base plate 1. The adjusting assembly drives the pin 32 and the support plate 34 to be inserted into the hollow cylinder 31. The elastic component supports the support plate 34 to contact the hollow cylinder 31. The lifting component can adjust the height of the pin 32, thereby driving the pin 32 to insert or disengage from the hollow cylinder 31. When the pin 32 is inserted into the hollow cylinder 31, the positioning plate 33 abuts against the top of the hollow cylinder 31, and the adjustment can be stopped. The elastic component pushes the support plate 34 to contact the inner wall of the hollow cylinder 31, driving the support plate 34 to continuously contact the hollow cylinder 31, thereby compensating for wear caused by friction and avoiding loosening due to control. The extension component expands the contact area with the ground, thereby ensuring the stability of the base plate 1 and the guardrail 21 during installation. The guardrail 21 can be installed by bolts or welded to the top of the base plate 1. The specific connection method can be selected according to actual production.

[0023] Please see Figure 4 A further solution based on this embodiment is as follows: four support plates 34 are provided, and the four support plates 34 are evenly distributed in a circumferential array outside the pin 32. The four support plates 34 simultaneously contact the hollow cylinder 31 to expand the contact area, thereby ensuring the stability of the connection between the pin 32 and the hollow cylinder 31.

[0024] Please see Figure 1 , 2A further solution based on this embodiment is as follows: the lifting assembly includes a threaded rod 22 rotatably connected to the guardrail 21 and a slider 23 threadedly connected to the threaded rod 22. The rotation of the threaded rod 22 drives the slider 23 together with the pin 32 to move through the threaded pair. The thread makes the positioning plate 33 tightly abut against the top of the hollow cylinder 31 to prevent the slider 23 from moving up and down and to stabilize the position of the pin 32.

[0025] Please see Figure 2 A further solution based on this embodiment is: the guardrail 21 has a matching groove at the corresponding position of the slider 23, and the slider 23 slides inside the groove. The groove limits the slider 23, making the slider 23 slide more smoothly and stably, and it will not rotate with the threaded rod 22, thus avoiding jamming during adjustment.

[0026] Please see Figure 4 A further solution based on this embodiment is as follows: the elastic component includes a damping block 41 and a first spring 42 fixedly connected between the pin 32 and the support plate 34. The first spring 42 pushes the support plate 34 to move away from the pin 32. Through the extensibility of the first spring 42, the support plate 34 is continuously in contact with the hollow cylinder 31. The damping block 41 can absorb vibration. The damping block 41 can be made of butyl rubber, such as "butyl gold damping sheet", which has excellent corrosion resistance, no corrosive effect on metals, plastics, rubber and other materials, and no irritation to human skin. Its closed-cell structure can effectively isolate corrosive media while maintaining damping performance.

[0027] Please see Figure 1 , 5 A further solution based on this embodiment is as follows: the extension component includes a connecting plate 51 fixedly connected to the base plate 1, an extension plate 52 rotatably connected to the base plate 1, a plug rod 53 slidably connected to the base plate 1, a pull ring 54 fixedly connected to the top of the plug rod 53, and a second spring 55 fixedly connected between the pull ring 54 and the base plate 1. The extension plate 52 rotates to contact the ground where the base plate 1 is installed. It can pass through the hole on the connecting plate 51 to initially position the base plate 1. Then, the extension plate 52 is rotated to extend, increasing the contact with the ground and avoiding the problem that the guardrail 21 has a high center of gravity and is easy to tip over.

[0028] Please see Figure 5 A further solution based on this embodiment is: the extension plate 52 has a locking hole at the corresponding position of the insertion rod 53, and the insertion rod 53 is locked inside the locking hole, which can position the extension plate 52 and prevent the extension plate 52 from rotating on its own.

[0029] Working principle: When connecting multiple guardrails 21, rotate the threaded rod 22 to raise the position of the pin 32. Then, align the hollow cylinder 31 with the corresponding position at the bottom of the pin 32. Then, rotate the threaded rod 22 in the opposite direction to drive the slider 23 to descend. The slider 23 drives the pin 32 to descend. The pin 32, together with the support plate 34, is inserted into the interior of the hollow cylinder 31 until the positioning plate 33 abuts against the top of the hollow cylinder 31. Then, stop rotating the threaded rod 22. At this time, the damping block 41 and the first spring 42 make the support plate 34 fit tightly against the inner wall of the hollow cylinder 31. First, pull up the pull ring 54. The pull ring 54 drives the insertion rod 53 and stretches the second spring 55 at the same time. Then, rotate the extension plate 52 ninety degrees and then release the pull ring 54. The second spring 55 retracts the insertion rod 53 to reset, thus locking it into the locking hole of the extension plate 52. The cone can be inserted into the soil through the hole on the connecting plate 51.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
