Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a portable safety belt fastener. Background Art

[0002] In construction projects, the scaffolding is usually erected 1.5 meters above the working surface. However, for the safety of personnel at the construction site, the scaffolding is usually erected about 2 meters above the working surface to serve as a hanging point for personnel safety belts. For those temporary operating frames, such construction is not only inconvenient but also leads to increased construction costs.

[0003] To this end, we propose a portable seat belt fastener. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a portable safety belt fastener.

[0005] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present utility model is:

[0006] A portable safety belt anchor comprises: a fixing tube, the bottom of which is inserted into a steel tube of a scaffold, the fixing tube being limited by a limiting mechanism and the inner wall of the steel tube of the scaffold, the limiting mechanism being arranged in the fixing tube; and a hanging ring, which is arranged on the tube wall at the upper part of the fixing tube and is used for hanging a safety belt.

[0007] By setting a fixed tube and a hanging ring for hanging a safety belt on the fixed tube, when working, the bottom of the fixed tube is inserted into the steel tube of the scaffolding, and the limiting mechanism limits the steel tube of the scaffolding to prevent the fixed tube from easily falling out of the steel tube of the scaffolding. This arrangement does not require a separate safety belt hanging point, saving construction costs. It is also easy to carry and use, and solves the problem of inconvenience in hanging a safety belt when working on the top of the scaffolding.

[0008] It is further defined that the fixed pipe includes an upper fixed section and a lower plug-in section, the outer diameter of the plug-in section matches the inner diameter of the steel pipe of the scaffolding, the outer diameter of the fixed section is larger than the outer diameter of the plug-in section, and a hanging ring is provided on the fixed section; in this way, the fixed pipe is divided into a fixed section and a plug-in section, and the plug-in section forms a limit on the insertion depth, which is more convenient to use and can be inserted into place.

[0009] It is further defined that the limit mechanism includes two limit rods and a return spring, the two limit rods are hinged in a scissor shape through a hinge shaft, the two ends of the hinge shaft are passed through the connection between the fixed section and the plug-in section, two connecting columns are provided on the inner sides of the tops of the two limit rods, the two ends of the return spring are respectively passed through the two connecting columns, the bottom outer sides of the two limit rods are provided with a horizontal anti-slip block, the top outer sides are provided with a horizontal pushing block, the side wall of the fixed section is provided with a pressing hole for pressing the anti-slip block, and the return spring is provided with a pressing hole for pressing the anti-slip block. When the spring is not under stress, the outer end of the anti-slip block extends out of the plug-in section; the two limit rods are hinged in a scissor shape, a pushing block is set at the top of the limit rod and an anti-slip block is set at the bottom, the pushing block is pressed through the pressing hole, the return spring is compressed, and the outer side of the anti-slip block is retracted into the plug-in section. At this time, the plug-in section is inserted into the steel pipe of the scaffolding. After it is fully inserted, the pushing block is released, the return spring is extended, and the anti-slip block is pushed out to contact the inner wall of the steel pipe of the scaffolding to form friction, which plays an anti-slip effect. The structure is simple and the operation is convenient.

[0010] It is further defined that it also includes a pushing mechanism, which is used to push the pushing block to move inward. The pushing mechanism includes a handle, a pushing block and a pull rope. The upper end of the handle is hinged to the tube wall of the fixed section through a hinge seat, and the pushing block is arranged on the inner side of the lower end of the handle. The two ends of the pull rope are respectively connected to the lower end of the handle and the tube wall of the fixed section. When the return spring is in a non-stressed state, the pushing block contacts the push block and the pull rope is in a taut state, and there is a gap fit between the push block and the pressing hole; a pushing mechanism is set to press the handle, and the lower section of the handle is pressed inward, driving the push block to extend into the pressing hole, thereby pushing the pushing block, which is more labor-saving and convenient. The gap fit between the push block and the pressing hole can ensure that the pushing block is not restricted when rotating around the hinge seat.

[0011] It is further defined that the anti-slip block is coated with a rubber layer; coating the anti-slip block with a rubber layer can increase the friction with the inner wall of the steel pipe of the scaffolding and improve the limiting effect.

[0012] It is further defined that the pushing block, the limiting rod and the anti-falling block are made as one body.

[0013] The beneficial effects of the utility model are as follows: by arranging the plug-in section and the limiting mechanism, the fixing pipe is inserted into the steel pipe of the scaffold and fixed, and the safety belt is hung on the hanging ring, thereby avoiding the process of separately setting the safety belt hanging point and reducing the construction cost.
