Description

Technical Field

[0001] This utility model relates to the field of fall protection technology for high-altitude operations, specifically to a full-body safety belt with left and right hip node modules. Background Technology

[0002] Full-body harnesses are the most important equipment for working at heights. They typically have two fall arrest points: one on the chest and one on the back. The chest fall arrest point, which primarily absorbs the impact of a fall, has a main webbing strip running from the chest to the hips. The back fall arrest point, which primarily absorbs the impact of a fall, has a main webbing strip running from the waist to the front legs. These webbing strips intersect at the left and right hips. Therefore, the arrangement of these webbing strips is crucial to the overall effectiveness of the full-body harness in protecting the worker's life during a fall.

[0003] However, most existing full-body seat belts are constructed by simply stitching webbing together in two directions: from the chest to the buttocks and from the lower back to the front legs. This structure has the following disadvantages:

[0004] 1. When workers are wearing full-body safety harnesses at heights, the webbing in the two directions interferes with each other, causing the webbing to twist and deform. This twisting may cause the webbing pattern to crack, posing a safety hazard. 2. Due to the interlacing of the webbing, it is impossible to design webbing adjustment devices at or near the location of the interlacing, causing significant discomfort to the wearer. 3. The relative angle between the webbing in the two directions cannot be effectively controlled within a reasonable range for worker comfort.

[0005] To address this, a full-body seatbelt with left and right hip node modules is proposed to prevent webbing from interfering with each other while improving the comfort of the wearer. Utility Model Content

[0006] The purpose of this utility model is to provide a whole-body seat belt left and right hip node module to overcome the structural defects of the existing whole-body seat belt with staggered left and right hip positions.

[0007] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0008] A full-body seat belt left and right hip node module includes a front webbing adjustment plate assembly and a rear webbing adjustment plate assembly. Both the front and rear webbing adjustment plate assemblies include a webbing adjustment plate, which is integrally formed. A fixed main shaft is rotatably connected between a pair of webbing adjustment plates. An angle limiting member is installed on the side of the pair of webbing adjustment plates that are close to each other. The pair of angle limiting members form a cross shape and can contact each other. The pair of webbing adjustment plates, the pair of angle limiting members, and the fixed main shaft are all arranged on the same axis. Each pair of webbing adjustment plates has a pair of wide webbing mounting holes and a pair of narrow webbing mounting holes, and the pair of narrow webbing mounting holes is located between the pair of wide webbing mounting holes.

[0009] Furthermore, the outer side of the webbing adjustment plate is provided with a pair of adjustment paddles near a pair of webbing mounting holes. The adjustment paddles have a central webbing mounting hole. The webbing adjustment plate and adjustment paddles are suitable for webbing with a width of 40mm to 46mm. At the same time, the free end of the webbing has a webbing end flap, which is used to abut against the central webbing mounting hole.

[0010] Furthermore, a pair of adjusting paddle limiting shafts are installed on the outer side of the webbing adjusting plate. The adjusting paddles have openings, and the adjusting paddle limiting shafts and openings are rotatably connected.

[0011] Furthermore, a baffle is installed at the free end of the adjusting paddle limit shaft.

[0012] Furthermore, each of the pair of webbing adjustment plates has a pair of stepped steps on the side that is close to each other, and the pair of stepped steps are respectively located at the edge of the pair of webbing mounting holes. Each of the pair of stepped steps is equipped with rubber and plastic anti-slip parts, and the surface of the rubber and plastic anti-slip parts is provided with anti-slip teeth to prevent the webbing from slipping when adjusting the length.

[0013] Furthermore, a wear-resistant protrusion is installed on the outer side of a pair of webbing adjustment plates near the middle, and a webbing installation transverse hole is opened on the side of the wear-resistant protrusion through the wear-resistant protrusion.

[0014] Furthermore, the rotation angle between a pair of webbing adjustment plates is limited to between 60° and 120° by a pair of angle limiting members.

[0015] Furthermore, the webbing adjustment plate has a rope mounting hole near its bottom for hanging the accompanying tool bag.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] I. The left and right hip node modules of this utility model are used in conjunction with the full-body safety belt. As an important accessory of the full-body safety belt, it replaces the structure of most existing full-body safety belts that are connected by webbing stitched together at the left and right hip positions. When in use, the main webbing from the chest to the buttocks at the front fall arrest point of the full-body safety belt, which mainly bears the impact of a fall, and the main webbing from the waist to the front legs at the back fall arrest point, which mainly bears the impact of a fall, intersect at the left and right hip positions. The node module of this utility model separates these two important webbings, avoiding damage to the webbing or even the entire full-body safety belt caused by irregular deformation, twisting, or cutting of the webbing in both directions under stress. The left and right hip node modules of the full-body safety belt provide greater safety protection for workers at heights.

[0018] 2. The left and right hip node modules of this utility model's full-body safety belt can be used in two ways: with a single webbing or with segmented webbing, providing more options for safety belt design and users. When used with a single webbing, the webbing passes through multiple webbing mounting holes, increasing friction under stress and effectively reducing webbing slippage within the components, resulting in more stable positioning of each component of the safety belt. When used with segmented webbing, the left and right hip node modules of the full-body safety belt can bear the tension of the webbing on both sides through the strength of their single-sided components. Simultaneously, the webbing adjustment devices on each side can adjust to a fixed length for wearers of different heights and body types, making the same full-body safety belt more suitable for different workers and improving the comfort of workers performing high-altitude work. In addition, the rubber and plastic anti-slip parts embedded in the webbing adjustment plate assembly, which come into contact with the webbing, further prevent the webbing from slipping through their spikes. This means that when wearing a full-body harness, the person working at height does not need to frequently tighten the webbing end, which is affected by shaking and the webbing's varying tightness.

[0019] 3. When manufacturing a full-body seatbelt, for the intersection of the webbing at the left and right hips, installation is simply completed by threading the webbing through the corresponding mounting holes on the node module according to the preset usage method. This makes the manufacturing of full-body seatbelts more convenient and faster while offering more functionality, avoiding the quality inconsistencies caused by traditional methods of sewing webbing together.

[0020] 4. The front and rear webbing adjustment plate assemblies rotate as personnel climb, walk, or engage in other activities. Compared to traditional webbing stitching methods, this significantly improves personnel comfort. Simultaneously, the unique angle adjustment device limits the interlacing angle of the front and rear webbing adjustment plates to a reasonable 60° to 120°, ensuring both convenient and safe operation for personnel.

[0021] 5. The left and right hip joint modules of this utility model are equipped with wear-resistant protrusions on the outermost side to prevent damage to the webbing on both sides, which are the main load-bearing components, due to personnel passing through narrow areas or scraping against walls, etc. The tool mounting holes at the bottom can be used to install ropes and carry a small number of tools or tool bags, bringing more practicality to the workers' wearing and use of the safety belt.

[0029] 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.

[0030] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a full-body seat belt left and right hip node module, which is a component of the full-body seat belt. When a person wears the full-body seat belt, this component is located at the left and right hip positions. It includes a front webbing adjustment plate assembly 1 and a rear webbing adjustment plate assembly 3. Both the front webbing adjustment plate assembly 1 and the rear webbing adjustment plate assembly 3 include webbing adjustment plates 11. A fixed main shaft 2 is rotatably connected between a pair of webbing adjustment plates 11. Angle limiting members 111 are installed on the side of the pair of webbing adjustment plates 11 that are close to each other. The pair of angle limiting members 111 form a cross shape and can contact each other. The pair of webbing adjustment plates 11, the pair of angle limiting members 111, and the fixed main shaft 2 are all arranged on the same axis. Each pair of webbing adjustment plates 11 has a pair of webbing mounting wide holes 112 and a pair of webbing mounting narrow holes 113, and the pair of webbing mounting narrow holes 113 are located between the pair of webbing mounting wide holes 112.

[0031] As an embodiment of the present invention, the outer side of the webbing adjustment plate 11 is provided with a pair of adjustment paddles 12 near a pair of webbing mounting holes 112, and the adjustment paddles 12 have a central webbing mounting hole.

[0032] As an embodiment of this utility model, a pair of adjusting paddle limiting shafts 13 are further installed on the outer side of the webbing adjusting plate 11. The adjusting paddle 12 has an opening, and the adjusting paddle limiting shaft 13 and the opening are rotatably connected.

[0033] As an embodiment of this utility model, a baffle is further installed on the free end of the adjusting paddle limiting shaft 13.

[0034] As an embodiment of the present utility model, the pair of webbing adjustment plates 11 are further provided with a pair of stepped steps on the side that is close to each other, and the pair of stepped steps are respectively located at the edge of the pair of webbing mounting wide holes 112. Rubber and plastic anti-slip parts 14 are installed in the pair of stepped steps, and the surface of the rubber and plastic anti-slip parts 14 is provided with anti-slip teeth.

[0035] As an embodiment of the present invention, further, a wear-resistant protrusion 115 is installed on the outer side of a pair of webbing adjustment plates 11 near the middle, and a webbing mounting transverse hole 114 penetrating the wear-resistant protrusion 115 is provided on the side of the wear-resistant protrusion 115.

[0036] As an embodiment of the present invention, the rotation angle between a pair of webbing adjustment plates 11 is further limited to between 60° and 120° by a pair of angle limiting members 111.

[0037] Specifically, the left and right hip joint modules of the full-body safety belt of this utility model have the following two main usage methods:

[0038] 1. For example Figure 4 As shown, the main webbing from the chest to the buttocks of the full-body seat belt passes sequentially through the webbing mounting gap between the front webbing adjusting plate assembly 1 and the rear webbing adjusting plate assembly 3, through the wide webbing mounting hole 112, the center webbing mounting hole of the adjusting lever 12, the narrow webbing mounting hole 113, the transverse webbing mounting hole 114, another narrow webbing mounting hole 113, the center webbing mounting hole of the adjusting lever 12, and the wide webbing mounting hole 112, before exiting. When the webbing is subjected to force at one end after passing through these mounting holes, it cannot slide due to the friction between the webbing and the mounting holes of the webbing adjusting plate 11, thus securing the webbing, which is the main force-bearing component of the full-body seat belt. The main webbing from the lower back to the front legs of the full-body seat belt is installed on the rear webbing adjusting plate assembly 3, which is identical to the front webbing adjusting plate assembly 1, and the installation method is the same. After the webbing is installed, the main webbing from the chest to the buttocks and the main webbing from the lower back to the front legs of the full-body seat belt are interlaced and separated through the left and right hip node modules of the full-body seat belt, while ensuring the positioning of the webbing at the node position of the full-body seat belt.

[0039] 2. For example Figure 5 As shown, the main webbing from the chest to the hips and the main webbing from the lower back to the front legs of the full-body seat belt are segmented. Taking the main webbing from the chest to the hips as an example, the end of the webbing on one side is inserted into the installation gap of the node module and then passes through the central webbing installation hole of the adjusting lever 12. After that, it returns to the installation gap of the node module through the gap between the adjusting lever 12 and the wide webbing installation hole 112, and passes through close to the rubber and plastic anti-slip part 14. Then, an anti-slip module is sewn onto the webbing end 5, and the webbing installation on that side is completed. The webbing installation method on the other side of the front webbing adjusting plate assembly 1 and the rear webbing adjusting plate assembly 3 is the same as the above method. After the webbing is installed, when the non-end side of the webbing is subjected to force, the adjusting lever 12 moves outward along the adjusting lever limiting axis 13 due to the force on the webbing, causing the webbing between it and the wide webbing installation hole 112 to be squeezed, ultimately achieving locking of the webbing end and bearing the force. The tension is transmitted through the front webbing adjustment plate 11 to the same structure on the other side, thus realizing the transmission of force between the webbing on both sides of the front webbing adjustment plate assembly 1 when the whole-body seat belt is under overall force. At this time, the webbing adjustment plate assembly body will act as the main force-bearing component. When the whole-body seat belt is not under force, the person can pull the webbing by hand, which will move the adjustment lever 12 along the center side, increasing the gap for accommodating the webbing, thereby realizing the adjustment of the webbing length. The left and right hip node modules of the whole-body seat belt are used as the webbing length adjustment device in four directions.

[0040] When workers are wearing full-body safety harnesses, the webbing that crosses at the left and right hip positions of the left and right hip nodes of the full-body safety harness will rotate. At the same time, the angle limiting component 111 limits the rotation angle to a reasonable angle, which not only prevents the webbing from twisting and curling, but also prevents the full-body safety harness from failing due to excessive change in angle.

[0041] When personnel are working while wearing full-body safety harnesses, the webbing wrapped around the metal parts experiences frequent tightening and loosening, which can cause the webbing to slip. The rubber and plastic anti-slip component 14 embedded in the front webbing adjustment plate assembly 1 can effectively prevent this gradual slippage.

[0042] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.
