Description

Technical Field

[0001] This utility model belongs to the field of building scaffolding installation technology, and in particular relates to a fall-prevention safety locking device structure for building scaffolding. Background Technology

[0002] Construction scaffolding is a temporary working platform or access route erected to ensure the smooth progress of construction. It is usually composed of poles (such as steel pipes), connectors (fasteners) and other accessories, and can be assembled into various forms according to project needs, such as ground-mounted, cantilevered or attached lifting scaffolding.

[0003] Traditional construction scaffolding typically uses two clamps to connect and fix the ends of two steel pipes when using locking devices. This method results in a small fixed area for the steel pipes, leading to insufficient overall stability. Under strong impacts or severe shaking, the steel pipes are prone to detaching from the clamps, causing them to fall and posing a serious safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a fall-prevention safety locking device structure for construction scaffolding. By setting up an anti-fall mechanism, specifically, the scaffolding is positioned and fitted onto a sleeve, then a pin is inserted into the sleeve and the scaffolding, and a nut is installed to restrict the pin, thereby preventing the scaffolding from falling. Subsequently, two clamping blocks are used to lock and fix the scaffolding in place with fixing bolts and locking nuts, improving the fixing effect, making the contact area of ​​the scaffolding after installation larger, and the fixation more secure, greatly reducing the possibility of shaking. This solves the problem of traditional construction scaffolding using locking devices, which usually uses two clamping blocks to connect and fix the ends of two steel pipes. This method results in a small fixed area of ​​the steel pipe, insufficient overall stability, and easy for the steel pipe to detach from the clamping blocks, thus causing a fall.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a fall-prevention safety lock structure for construction scaffolding, including a lock fixing block, with the scaffolding mounted on top of the lock fixing block, and a positioning protrusion fixedly connected to the bottom outer surface of the scaffolding. It also includes:

[0007] The anti-fall-off mechanism consists of two sets, located at the top and bottom of the lock fixing block, respectively. The upper anti-fall-off mechanism includes a sleeve fixedly connected to the top of the lock fixing block. Both the sleeve and the scaffolding have insertion holes, into which pins are inserted. Two clamping blocks are provided at the top of the sleeve. Two fixing bolts are fixedly connected to the clamping block on the left side, and locking nuts are threaded onto the fixing bolts. The fixing bolts and clamping blocks are integrally formed.

[0008] The sleeve has a positioning groove on its front side, the scaffold is placed between two clamping blocks, and the scaffold is inserted into the sleeve.

[0009] Furthermore, the positioning protrusion is positioned and inserted into the positioning groove, one end of the pin is fixedly connected to a limiting protrusion, and the other end of the pin is fixedly connected to a threaded shaft, on which a nut is threaded; when the pin is inserted into the sleeve and scaffold, and the nut is installed on one end of the threaded shaft of the pin, the cooperation between the nut and the limiting protrusion will restrict the pin and prevent it from falling off.

[0010] Wherein, after the scaffold is inserted into the sleeve, the insertion hole on the scaffold corresponds to the insertion hole on the sleeve, and the pin is used to restrict the scaffold on the sleeve.

[0011] Furthermore, the inner wall of the clamping block is fixedly connected with several protrusions, and the clamping block is semi-circular. The clamping block contacts the surface of the scaffolding through the protrusions on the inner wall. The two clamping blocks are pushed to clamp the scaffolding, and then the two clamping blocks are locked and fixed with locking nuts to clamp and fix the scaffolding.

[0012] Furthermore, a number of connecting rods are fixedly connected to the outer end of the clamping block, and a connecting seat is slidably connected to the outer side of the connecting rod. The bottom of the connecting seat is fixedly connected to the top of the sleeve. The connecting rod slides through the connecting seat and extends to the outside. The connecting rod and the connecting seat cooperate to support the clamping block. The side of the connecting rod away from the clamping block is protruding. When the clamping block moves, the connecting rod will slide on the connecting seat, so that the clamping block moves in a straight line.

[0013] Furthermore, a rotating ring is provided on the outer side of the lock fixing block, and a mounting plate is fixedly connected to the back of the rotating ring. A limiting ring is fixedly connected to the inner wall of the rotating ring. An annular limiting groove is opened on the outer surface of the lock fixing block, and the limiting ring is rotatably connected in the limiting groove. The rotating ring rotates on the lock fixing block through the limiting ring, which can adjust the angle of another lock.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model sets up an anti-fall-off mechanism, specifically by positioning the scaffolding onto the sleeve, then inserting pins into the sleeve and scaffolding and installing nuts to restrict the pins, thereby preventing the scaffolding from falling off. Then, two clamps are used to lock and fix the scaffolding with fixing bolts and locking nuts, improving the fixing effect, making the contact area of ​​the scaffolding larger after installation, making the fixation more secure, and greatly reducing the occurrence of shaking.

[0016] 2. This utility model features a rotating ring, specifically, another set of locks can be installed on the mounting plate with screws, and the rotating ring rotates on the lock fixing block through a limiting ring, which can adjust the angle of the other lock. The lock can be adjusted to a suitable position according to the installation situation to meet different installation needs of scaffolding.

Two fixing bolts 234 are fixedly connected to the clamping block 23 on the left side. Locking nuts 235 are threaded onto the fixing bolts 234. The scaffold 11 is positioned. The scaffold 11 is fitted onto the sleeve 21, and then the pin 22 is inserted into the sleeve 21 and the scaffold 11 and a nut is installed to secure the pin, thereby preventing the scaffold 11 from falling off. Then, the two clamping blocks 23 are used to lock and fix the scaffold 11 with the cooperation of the fixing bolts 234 and the locking nut 235, which improves the fixing effect, makes the contact area of ​​the scaffold 11 larger after installation, and makes the fixation more secure, greatly reducing the possibility of shaking. The sleeve 21 has a positioning groove 211 on the front, and the scaffold 11 is placed between the two clamping blocks 23, and the scaffold 11 is inserted into the sleeve 21.

[0029] The positioning protrusion 111 is positioned and inserted into the positioning groove 211. One end of the pin 22 is fixedly connected to the limiting protrusion 221, and the other end of the pin 22 is fixedly connected to the threaded shaft, on which a nut is threaded.

Then, the two clamping blocks 23 are pushed, and the connecting rod 232 slides on the connecting seat 233. The fixing bolt 234 is inserted into the other clamping block 23. The two clamping blocks 23 are then locked and fixed with the locking nut 235. At this time, the protrusion 231 will contact the surface of the scaffold 11 to increase the friction and improve the fixing effect of the scaffold 11, thus completing the installation of the scaffold 11.
