AI Technical Summary
In modern construction, traditional wire rope or suspender binding methods in high-altitude hoisting operations are prone to be unreliable due to human factors, which may cause safety accidents such as tilting and falling off of the hanging object. Moreover, the weight of the hanging object itself may cause the wire rope or suspender to be twisted and deformed.
A high-altitude safety lock box for lifting a building is designed, made of high-strength stainless steel, with anti-slip texture inside, and slots are opened on both sides to install spring pins. The spring pin includes threaded pin rods, limit nuts, springs and cross baffles. By adjusting the position of the spring pins, it is suitable for lifting construction of different sizes to ensure that the lock box fits with the hanging object.
Effectively prevent lifting and falling off problems, improve construction safety, ensure that the spreader is firm and reliable, reduce construction costs, and the device is safe and environmentally friendly, and can be recycled.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction, in particular to a safety lock box for high-altitude hoisting of buildings. Background Technique
[0002] In modern building construction, high-altitude hoisting operations are a common and crucial task. At present, during the hoisting of steel structure purlins and roof panels, the traditional method is to use steel wires or slings to bundle materials for hoisting. However, due to human factors, there is a possibility that the binding is not firm and the lifting points are asymmetric, resulting in tilting and falling during the hoisting process, leading to safety accidents. Moreover, due to the weight of the lifted object, the steel wires and slings may also be distorted and deformed at the contact parts with the lifted object during the hoisting process. Content of the Utility Model
[0003] The purpose of the utility model is to provide a safety lock box for high-altitude hoisting of buildings to solve the problems raised in the above background technique.
[0004] To solve the above technical problems, the utility model provides the following technical solution: A safety lock box for high-altitude hoisting of buildings, including a lock box. A slot is opened on one long side of the lock box. A spring pin is installed in the slot. The spring pin includes a threaded pin rod, a limit nut, a spring, and a cross baffle. One end of the threaded pin rod passes through the slot and is connected to the cross baffle, and the other end is slidably connected to the long side of the lock box in cooperation with the limit nut. One end of the spring is fixedly connected to the cross baffle, and the other end abuts against the inner wall of the slot. The spring pin can move freely along the long side direction of the slot.
[0005] As a further description of the above solution, the lock box is made of high-strength stainless steel material, and the inner surface is provided with anti-slip patterns.
[0006] As a further description of the above solution, the diameter of the limit nut is greater than the width of the slot.
[0007] As a further description of the above solution, the horizontal and vertical dimensions of the cross baffle are both greater than the width of the slot.
[0008] As a further description of the above solution, a lifting ring is installed on the outer side of the long side of the lock box without a slot.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] The utility model uses a square stainless steel lock box as a carrier, which is firm and durable, not easy to deform. Spring pins are installed through slots on both sides, and the position can be flexibly adjusted, suitable for hoisting structures of any size. The lock box has a high degree of fit with the lifted object, and the lifting tool is firm and reliable, which can effectively prevent the problem of lifting and falling, improve construction safety. The whole device is safe, environmentally friendly, recyclable, and can reduce construction costs. Brief Description of the Drawings

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0016] As Figures 1-3 shown, this embodiment provides a safety lock box for high-altitude hoisting of buildings, including a lock box. A slot 2 is provided on one long side of the lock box 1, and a lifting ring 4 is installed outside the other long side. A spring pin 3 is installed in the slot 2. The spring pin 3 includes a threaded pin rod 3.1, a limit nut 3.3, a spring 3.4, and a cross baffle 3.2. One end of the threaded pin rod 3.1 passes through the slot 2 and is connected to the cross baffle 3.2, and the other end is slidably connected to the long side of the lock box 1 in cooperation with the limit nut 3.3. One end of the spring 3.4 is fixedly connected to the cross baffle 3.2, and the other end abuts against the inner wall of the slot 2. The spring pin 3 can move freely along the long side direction of the slot 2. By adjusting the position of the spring pin 3 in the slot 2, it is used to adapt to hoisting structures of different sizes, so that the lock box 1 fits perfectly with the lifted object.
[0017] As Figure 1 shown, the lock box 1 is made of high-strength stainless steel material, and the inner surface is provided with anti-slip lines to increase the friction with the lifted object and further improve the stability of hoisting.
[0018] As shown Figure 2 As shown, the diameter of the limit nut 3.3 is greater than the width of the slotted groove 2 to prevent the threaded pin rod 3.1 from completely disengaging from the slotted groove 2.
[0019] As shown Figure 1 As shown, both the horizontal and vertical dimensions of the cross baffle 3.2 are greater than the width of the slotted groove 2, so as to effectively block the threaded pin rod 3.1 and prevent it from falling into the interior of the slotted groove 2 during movement.
[0020] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
