Description

Technical Field

[0001] The utility model relates to the technical field of safety clothing, in particular to a connection and hanging point of a safety clothing for high-altitude operations that is resistant to breaking. Background Art

[0002] Aerial work refers to work performed in a high-altitude environment, such as cleaning the exterior walls of buildings, maintenance of large machines, installation of wires and cables, roof repairs, etc. In aerial work, workers face dangers such as wind and rain, falling objects, and electric shocks. Therefore, effective safety measures must be taken. Safety clothing is one of the necessary safety equipment for aerial work. It has functions such as protection, heat preservation, cold protection, rain protection, and wind protection, which can ensure the safety and comfort of workers in aerial work. At the same time, the choice of safety clothing is also very important. Different safety clothing is suitable for different aerial work environments. Improper selection will increase the safety risks of workers. For example, in aerial work without protective structures, it is necessary to wear safety clothing with hanging points. By hanging one end of the safety rope on the fixed anchor point and the other side on the hanging point of the safety clothing, workers can be protected when they fall accidentally during aerial work. However, due to the limited maximum tension on the hanging point of the safety clothing, if the hanging point is not used correctly according to regulations, the hanging point will be overstressed and instantly broken, which is not conducive to the protection of workers. Utility Model Content

[0003] The utility model aims to provide a connection and hanging point for safety clothing for high-altitude work which is resistant to breaking, so as to solve the problem of the safety clothing hanging point being broken by excessive instantaneous pulling force proposed in the above-mentioned background technology.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-6The utility model provides a technical solution: a connection hanging point for a safety clothing for high-altitude work that is resistant to breaking, comprising a fixing plate 1, a connecting belt 2 is sewn on the outer surface of the fixing plate 1, a limiting belt 3 is sewn on the outer surface of the connecting belt 2, and one end of a D-shaped ring 4 is arranged between the limiting belt 3 and the outer surface of the connecting belt 2, and an oblique pull mechanism is arranged on the outer surface of the fixing plate 1, which prevents the D-shaped ring 4 from being completely separated from the connection with the fixing plate 1 through the oblique pull structure.

[0029] The inclined-stay mechanism comprises: a limit seat 5, which is arranged on the outer surface of the fixed plate 1, and a connecting rod 6 is fixedly connected to the lower surface of the limit seat 5, and a locking bolt 7 is threadedly connected to the lower end of the connecting rod 6, a sliding limit rod 8 is installed inside the side surface of the limit seat 5, and one end of the limit rod 8 is fixedly connected to a connecting plate 9, and a return spring 10 is connected between the side surface of the connecting plate 9 and the side surface of the limit seat 5, the locking bolt 7 and the limit seat 5 are respectively located on both sides of the fixed plate 1, and the limit seat 5 is fixedly installed with the fixed plate 1 through the threaded connection of the locking bolt 7 and the connecting rod 6, the two ends of the limit rod 8 respectively penetrate the outer surfaces of both sides of the limit seat 5, and a clearance groove is opened on the upper surface of the limit seat 5 facing the plug-in board 11, and the clearance groove on the upper surface of the limit seat 5 is arranged opposite to the limit rod 8;

[0030] During installation, first insert the limit seat 5 into the fixed plate 1 through the connecting rod 6 and press the limit seat 5 onto the fixed plate 1 through the locking bolt 7, and then fix the fixed plate 1 to the hanging point position reserved for the safety clothing through the connecting piece. When the worker falls after the plug-in plate 11 is connected to the limit seat 5, the tension received by the D-shaped ring 4 is first transmitted to the connecting belt 2 and the limit belt 3. At this time, the connecting belt 2 and the limit belt 3 are deformed for buffering until the force generated by the fall is greater than the maximum force that the connection between the connecting belt 2 and the limit belt 3 and the fixed plate 1 can withstand. At this time, the connecting belt 2 and the limit belt 3 break and are disconnected from the fixed plate 1.

[0031] The inclined pull mechanism also includes: a plug-in board 11, which is arranged between two limit seats 5, and a holding column 12 is fixedly arranged on the upper surface of the plug-in board 11, and a clamping block 13 is fixedly arranged on the outer surfaces of both sides of the plug-in board 11, a connecting ring 14 is sleeved on the outer surface of the D-shaped ring 4, and an inclined belt 15 is connected between the outer surface of the connecting ring 14 and the upper surface of the plug-in board 11, the holding column 12 is a cylindrical design protruding from the upper surface of the plug-in board 11, and a hemispherical protrusion is arranged on the side surface of the holding column 12, and the clamping block 13 is a right-angled trapezoidal design, and the inclined surface of one end of the right-angled trapezoid of the clamping block 13 is arranged downward toward the fixed plate 1;

[0032] When installing the plug board 11, grasp the holding column 12 and press the plug board 11 downward through the block 13 to align it with the yield groove on the upper surface of the limit seat 5. The inclined surface of the block 13 squeezes the limit rod 8 so that the limit rod 8 slides and stretches the return spring 10 between the connecting plate 9 and the limit seat 5 until the block 13 completely slides to the bottom of the limit rod 8. The limit rod 8 slides and resets under the drive of the return spring 10 between the connecting plate 9 and the limit seat 5. At this time, the limit seat 5 maintains the limit of the plug board 11 through the limit rod 8. When the connecting belt 2 and the limit belt 3 are deformed, the plug board 11 applies tension to the D-shaped ring 4 from the side through the connecting ring 14 and the diagonal belt 15, thereby increasing the upper limit of the tension that the hanging point can withstand as a whole, thereby preventing it from breaking.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
