Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a protective device for building construction based on folding and telescopic mechanisms. Background Technology

[0002] Construction safety devices are crucial equipment for ensuring safety at construction sites and protecting construction workers and those in the surrounding area from accidental injuries. These devices are primarily used in high-risk environments such as working at heights, deep pits, and along work edges to reduce the occurrence of falls, falling objects, and other accidents. Common construction safety devices include guardrails, safety nets, and protective barriers, which are placed around the construction area or along the edges of high-altitude work platforms to provide isolation and protection.

[0003] Traditional protective devices mostly use fixed steel structures or mesh fences. While providing protection, these devices are usually bulky and difficult to reuse after use. Especially after a project is completed, many protective devices are difficult to disassemble and reuse due to damage or fixed installation, resulting in a lot of waste and resource depletion. In addition, most traditional protective devices cannot be adjusted in length or height according to actual construction needs, making them inflexible in different construction scenarios and unable to adapt to changing construction environments. The installation process is also relatively cumbersome, usually requiring the use of specialized tools and multiple people to complete, which not only increases installation time but also increases construction costs. Utility Model Content

[0004] The purpose of this invention is to provide a protective device for building construction based on folding and telescopic mechanisms, so as to solve the problem of poor adjustability of traditional protective devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a folding and telescopic protective device for construction, comprising a first support column, a base, diagonal bracing bars, and a locking mechanism. The base is located at the lower end of the first support column. Both the first support column and the base are U-shaped strips, with the width of the base being less than that of the first support column. Diagonal bracing bars are provided between the first support column and the base. Locking mechanisms are located at both ends of the first support column, each including a fixing ring. A release button is located on the outer side of each fixing ring, and a first spring is provided between the release button and the fixing ring. The first support column supports and secures the entire device. The base provides a stable foundation and supports the stability of the upper structure. The diagonal bracing bars provide additional support force to help maintain the stability of the support column. The locking mechanism locks and unlocks the support structure. The fixing rings secure the locking mechanism to the support structure. The release button unlocks the fixed structure. The first spring ensures that the locking mechanism can quickly reset after release.

[0006] Preferably, locking pins are provided on the left and right sides of the upper end of the diagonal brace, and a second spring is provided on the inner side of the locking pin. The locking pins play a fixing role between the diagonal brace and the support structure, and the second spring is used to hold the locking pins in a fixed position and provide a reset function.

[0007] Preferably, a movable shaft is provided between the diagonal brace and the base, and a rotating shaft is provided at the connection between the base and the end of the first support column. The movable shaft allows the angle between the diagonal brace and the base to be adjusted, and the rotating shaft allows the support structure to be rotated and folded when stored.

[0008] Preferably, the first support column is provided with several through holes, and a second support column is provided on the rear side of the first support column. The through holes are used to adjust the height or position of the support column, and the second support column provides additional support force.

[0009] Preferably, the inner sides of the first and second support columns are provided with sliding grooves, and the sliding grooves are provided with sliders. The sliding grooves provide a sliding path for the sliders, and the sliders adjust the relative position of the support structures by sliding.

[0010] Preferably, a first folding rod is provided between the first support column and the second support column, a rotating shaft is provided between the first folding rod and the slider, and a fastening bolt is provided on the rotating shaft. The first folding rod connects to the support column and provides a folding function. The rotating shaft enables the folding rod to rotate and adjust its angle, and the fastening bolt is used to fix the angle of the folding rod.

[0011] Preferably, a second folding rod is provided at the lower end of the first folding rod, the first folding rod and the second folding rod are placed crosswise, and a pivot is provided at the intersection point. The second folding rod cooperates with the first folding rod to complete the folding action.

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

[0013] 1. This folding and telescopic protective device for building construction can achieve flexible adjustment of height and length through the cooperation of the first and second support columns. The sliding groove and slider between the first and second support columns allow the support structure to slide freely, thus facilitating the adjustment of the size of the protective device according to construction needs. The folding rod, through the design of the cross structure, can save space when folding. At the same time, the design of the fastening bolts ensures the stability of the structure during use and will not affect the stability of the device due to changes in the angle of the folding rod.

[0014] 2. This folding and telescopic protective device for construction enhances the stability between the support column and the base by incorporating diagonal bracing bars. The diagonal bracing bars are connected between the base and the support column via a movable shaft, ensuring the entire device remains stable even under external impact. The locking mechanism, with its release button and retaining ring design, allows for quick locking and releasing when folding is required. The second spring ensures the reliability of the locking pin during reset, ensuring the diagonal bracing bars are always in the correct position during use, supporting the weight and pressure of the entire device.

[0015] 3. The folding and telescopic protective device for construction uses a base and a rotating shaft design that allows the entire device to be easily folded and unfolded for storage. The rotating shaft at the end of the base and the first support column allows the support column to be folded parallel to the base. The movable shaft allows the angle between the diagonal brace and the base to be flexibly adjusted, thus allowing the entire device to occupy less space when not in use, making it convenient for storage and transportation. At the same time, the through-hole design on the first support column allows for a more flexible connection between the diagonal brace and the support column, effectively improving the overall adjustability of the device.
