Description

Technical Field

[0001] This utility model relates to the technical field of construction safety protection equipment, and in particular to a fixing device for a safety protection net for building scaffolding with a snap-on connecting buckle. Background Technology

[0002] Safety nets for building scaffolding are essential safety facilities in high-altitude construction, used to shield against falling objects and prevent construction workers from accidentally falling.

[0003] In existing construction practices, these safety nets usually need to be fixed to the building's scaffolding panels or scaffolding poles. Traditional fixing methods often rely on using wire for wrapping and binding, or using bolts and pressure plates for perforation and fastening.

[0004] However, the above-mentioned fixing methods have drawbacks. Whether it is wire binding or bolt tightening, the installation and disassembly process is very cumbersome and requires a lot of manpower and time. Especially in high-altitude working environments, the operation is inconvenient and inefficient. The reliability of this connection method is not high. The wire is prone to rust and breakage, and the bolt is prone to loosening. Moreover, it is difficult to achieve standardized and rapid assembly and disassembly, which cannot meet the requirements of modern building construction for high efficiency and high safety.

[0005] Therefore, this utility model proposes a building scaffolding safety net fixing device with a snap-on connecting buckle to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the fixing devices for safety nets on building scaffolding, such as cumbersome and time-consuming installation and disassembly, the need for additional tools, low operating efficiency, and unstable fixing reliability, this utility model aims to provide a building scaffolding safety net fixing device with a snap-on connector that has an improved structure and can effectively solve the above problems.

[0007] This utility model provides a building scaffold safety net fixing device with a snap-on connector. The fixing device is used to fix the building scaffold safety net with connecting columns to the building scaffold plate, and includes a fixing mechanism.

[0008] The fixing mechanism includes a first sleeve fixed to the outer frame plate, an mounting plate fixedly connected to the top of the first sleeve, a connecting block slidably connected to the first sleeve along its axial direction, two clamping plates for clamping the connecting column rotatably connected to the connecting block, and two sliding pressure plates for pressing the clamping plates slidably connected to the mounting plate along its transverse direction.

[0009] Furthermore, the fixing mechanism also includes a first spring telescopic rod connected between the first sleeve and the connecting block, and a second spring telescopic rod connected between the mounting plate and the sliding pressure plate. Through the elastic force of the spring telescopic rod, the automatic reset and clamping functions of the clamping plate and the sliding pressure plate are realized.

[0010] Preferably, a lever is fixedly connected to the sliding pressure plate. The lever extends outward through the top of the mounting plate, allowing the user to drive the sliding pressure plate apart by moving the lever, thereby releasing the clamping plate.

[0011] Preferably, the fixing device further includes a protective mechanism, which includes a first support column and a second support column. The connecting column is fixedly connected to the bottom of the first support column and the bottom of the second support column, respectively. At least one sliding rod is slidably connected to the first support column and the second support column, and the protective net is slidably installed on the sliding rod to form the main frame of the protective net.

[0012] Preferably, the fixing device further includes a second sleeve, which is used to pass through and connect the adjacent first support column and the second support column. The top of the first support column and the second support column are provided with positioning holes for the second sleeve to pass through, thereby realizing the modular splicing of the protective mechanism.

[0013] Preferably, the splicing ends of the first support column and the second support column have a cross-sectional shape that is staggered and interlocked with each other. This structure helps to provide initial positioning and torsional resistance during docking.

[0014] Preferably, a pressing block is slidably connected inside the second sleeve, and multiple limiting sliders are slidably connected radially on the inner wall of the second sleeve. The outer side of the pressing block is provided with an inclined surface that cooperates with the limiting slider. A third spring telescopic rod for driving the pressing block to reset is also connected inside the second sleeve. Radial locking is achieved through the pushing and repelling action of the inclined surface.

[0015] Preferably, a lifting rod is fixedly connected to the top of the compression block, and the lifting rod extends outward through the top of the second sleeve, forming a manual operation component of the internal locking mechanism.

[0016] Preferably, an annular block is fixedly connected to the outer wall of the second support column near the top position. The inner wall of the annular block is provided with a limiting groove that matches the shape of the limiting slider. The limiting slider extends out under the push of the extrusion block and is inserted into the limiting groove to form a firm lock.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems of cumbersome installation and disassembly, low efficiency and unstable connection caused by the use of wire binding or bolt fixing of protective nets in the prior art by setting a fixing mechanism in which the first sleeve, clamping plate, connecting block, sliding pressure plate and the first and second spring telescopic rods work together. It achieves the technical effect of quick installation and disassembly without tools, convenient operation, reliable connection and high efficiency.

[0019] 2. This utility model solves the problems of difficult splicing and weak connection between protective net modules in the prior art by setting a second sleeve with a built-in extrusion block, limit slider and return spring to pass through and lock the adjacent first support column and second support column. It achieves the technical effect of modular rapid splicing, stable connection and improved overall protective structure.

[0020] 3. This utility model, through the separate and detachable design of the fixing mechanism and the protective mechanism, as well as the modular splicing structure of the protective mechanism itself, solves the problems of poor overall integrity and low component reuse rate of the existing safety protection net system, and achieves the technical effects of clear structure, high degree of standardization, easy storage, transportation and reuse, and reduced construction costs.

[0027] 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.

[0028] Please refer to Figures 1 to 4 This utility model provides a building scaffold safety net fixing device with a snap-on connector, which aims to solve the problems of existing building scaffold safety net fixing methods, which usually use wire binding or bolt fastening, resulting in cumbersome installation and disassembly, low efficiency, the need for additional tools, and unstable connection reliability.

[0029] like Figure 1 As shown, the building scaffolding safety net fixing device includes a fixing mechanism 1 and a protective mechanism 2. The fixing mechanism 1 is used to fix the device on the building scaffolding plate 101. The protective mechanism 2 is detachably installed on the building scaffolding plate 101 through the fixing mechanism 1. The fixing mechanism 1 serves as the installation base for the entire device, providing a quick and stable connection foundation for the protective mechanism 2.

[0030] Specifically, such as Figure 2As shown, the fixing mechanism 1 includes a first sleeve 102. The cylinder of the first sleeve 102 passes through the mounting hole opened on the building scaffolding plate 101 and is fixedly connected to the building scaffolding plate 101. A mounting plate 107 is fixedly connected to the top opening of the first sleeve 102. Inside the first sleeve 102, a connecting block 103 is slidably connected along the axial direction of the first sleeve 102. Two clamping plates 105 are rotatably connected to the top of the connecting block 103. The inner sidewalls of the two clamping plates 105 are provided with slots for clamping. The two clamping plates 105 can open and close relative to each other with their rotatable connection point as the axis, for clamping or releasing the connecting column 106 at the bottom of the protective mechanism 2. Between the bottom inner wall of the first sleeve 102 and the bottom of the connecting block 103, a first spring telescopic rod 104 is connected along the axial direction of the first sleeve 102. In its natural extended state, the first spring telescopic rod 104 continuously pulls the connecting block 103 together with the two clamping plates 105 connected thereto upwards into the first sleeve 102.

[0031] Furthermore, inside the mounting plate 107, two sliding pressure plates 108 are symmetrically slidably connected laterally. The inner end faces of the two sliding pressure plates 108 are used to abut against and press the outer walls of the two clamping plates 105 in the closed state, thereby applying radial pressure to the two clamping plates 105 to prevent them from accidentally opening. Between the inner side wall of the mounting plate 107 and the opposite outer sides of the two sliding pressure plates 108, a second spring telescopic rod 109 is connected. In the natural compression state, the second spring telescopic rod 109 continuously pushes the two sliding pressure plates 108 toward the center, making them tend to close. Each sliding pressure plate 108 is also fixedly connected to a lever 1011. The lever 1011 extends outward through the top of the mounting plate 107, making it convenient for the user to pull the two sliding pressure plates 108 outward, so that they overcome the elastic force of the second spring telescopic rod 109 and separate from each other.

[0032] like Figure 3 As shown, the protective mechanism 2 includes a first support column 201 and a second support column 203 as its frame. A downwardly extending connecting column 106 is fixedly connected to the bottom of the first support column 201 and the bottom of the second support column 203. The size and shape of the connecting column 106 are adapted to the slot on the inner side of the clamping plate 105. At least one sliding rod 202 is connected vertically between the first support column 201 and the second support column 203. The protective net 2011 is slidably installed on the sliding rod 202.

[0033] To achieve modular splicing of multiple protective mechanisms 2, positioning holes are provided at the top of the first support column 201 and the top of the second support column 203, respectively, for the second sleeve 205 to pass through. The splicing ends of the first support column 201 and the second support column 203 have a cross-sectional shape that is staggered and interlocked with each other. This structure helps to perform preliminary alignment and limiting during splicing. An annular block 204 is also fixedly connected to the outer wall of the second support column 203 near the top. A limiting groove is provided on the inner wall of the annular block 204 to cooperate with the subsequent locking structure.

[0034] The second sleeve 205 has a hollow cylindrical structure, with a pressing block 207 slidably connected inside. The outer surface of the pressing block 207 is set as an inclined surface that mates with the bottom of the limiting slider 209. Multiple limiting sliders 209 are slidably connected radially on the cylinder wall of the second sleeve 205. When the pressing block 207 moves axially, its outer inclined surface can push the multiple limiting sliders 209 to extend or retract radially. Inside the second sleeve 205, a third spring telescopic rod 208 is also connected for driving the pressing block 207 to automatically reset. The top of the pressing block 207... A lifting rod 206 is fixedly connected to the part. The lifting rod 206 extends outward through the top of the second sleeve 205. In the assembled state, the second sleeve 205 passes through the positioning holes of the adjacent first support column 201 and second support column 203. When their positions are aligned, the lifting rod 206 is released, and the third spring telescopic rod 208 pushes the pressing block 207, thereby pushing out multiple limiting sliders 209 radially and locking them into the limiting groove of the annular block 204. Through this built-in radial locking mechanism, the firmness and stability of the connection between adjacent protective mechanisms 2 are ensured.

[0035] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0036] As a preferred embodiment, to facilitate user operation of the sliding pressure plate 108 to release or clamp the connecting column 106, such as Figure 2 As shown, a lever 1011 is fixedly connected to each sliding pressure plate 108. The lever 1011 passes through a preset through hole on the mounting plate 107 and extends outward to form an easy-to-grip operating component.

[0037] As another preferred embodiment, in order to provide initial alignment and torsional resistance when splicing the first support column 201 and the second support column 203, such as Figure 3 As shown, the splicing ends of the first support column 201 and the second support column 203 have a cross-sectional shape that is staggered and interlocked with each other, thereby achieving rapid positioning and circumferential limiting during docking.

[0038] As a further preferred embodiment, in order to achieve convenient control of the internal locking structure of the second sleeve 205, such as Figure 4As shown, a lifting rod 206 is fixedly connected to the top of the extrusion block 207. The rod of the lifting rod 206 passes through the central hole at the top of the second sleeve 205 and extends upward. The user can drive the extrusion block 207 to move axially by lifting the lifting rod 206.

[0039] As another preferred embodiment, in order to provide a reliable locking target for the limiting slider 209, such as Figure 3 and Figure 4 As shown, an annular block 204 is fixedly connected to the outer wall of the second support column 203 near the top. An annular limiting groove is provided on the inner wall of the annular block 204. The cross-sectional shape of the limiting groove is adapted to the head shape of the extended end of the limiting slider 209. When the limiting slider 209 extends radially, its head can be accurately inserted into the limiting groove to form a firm axial and radial lock.

[0040] The working principle of this utility model's building scaffolding safety net fixing device with snap-on connector is as follows:

[0041] When installing the protective mechanism 2, the user first pulls the two levers 1011 outwards. The levers 1011 cause the two sliding pressure plates 108 to overcome the elastic force of the second spring telescopic rod 109 and separate from each other. At this time, the clamping force on the outside of the clamping plate 105 is released. Then, the connecting post 106 at the bottom of the protective mechanism 2 is aligned with the opening of the first sleeve 102 and inserted downwards. The bottom of the connecting post 106 pushes the connecting block 103 downwards and compresses the first spring telescopic rod 104. At the same time, the two clamping plates 105 can move together. The rotating mechanism opens to accommodate the connecting post 106. Once the connecting post 106 is inserted into place, the lever 1011 is released, and the second spring telescopic rod 109 resets, pushing the two sliding pressure plates 108 to close towards the center. This, in turn, presses the outer walls of the two clamping plates 105, ensuring that the clamping plates 105 firmly hold the connecting post 106. Simultaneously, the upward rebound force of the first spring telescopic rod 104 will lift the connecting block 103 and the connecting post 106 upward, eliminating gaps and completing a quick and stable installation. The disassembly process is the reverse operation.

[0042] When assembling two adjacent protective mechanisms 2, the user first aligns the adjacent first support column 201 and second support column 203. The staggered cross-sectional shapes of their ends can assist in positioning. Then, the user lifts the lifting rod 206 on the second sleeve 205. The lifting rod 206 drives the pressing block 207 to move upward and compress the third spring telescopic rod 208. The inclined surface on the outer side of the pressing block 207 moves away from the limiting slider 209, allowing the limiting slider 209 to retract radially inward. At this time, the second sleeve 205 is passed through the positioning holes at the top of the first support column 201 and the second support column 203 until its end reaches the position of the annular block 204. Then, the lifting rod 206 is released, and the third spring telescopic rod 208 resets and pushes the pressing block 207 downward. The inclined surface of the pressing block 207 forcefully pushes multiple limiting sliders 209 outward radially, and their heads are locked into the limiting grooves on the inner wall of the annular block 204, thereby achieving a firm mechanical lock between the two protective mechanisms 2.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
