Abstract
Description
Technical Field
[0001] The utility model belongs to the field of mine, tunnel mining and underground working wear, and in particular relates to a foldable inflatable back clip for underground mine protection. Background Art
[0002] At present, underground mining in mines in my country is becoming more and more frequent, and workers are required to continuously dig a large number of tunnels underground. However, the underground situation is complex and changeable, and personal safety is the primary consideration. At present, most of the mining back clips on the market are composed of straps, guard plates and connectors, with a relatively simple structure. Their protective performance does not meet the safety requirements of underground mining workers. In order to deal with this problem, buffer gaskets and thickened guard plates are used. However, thickened guard plates cause inconvenience in movement and heavy burden on operators during underground operations. Therefore, it is very necessary to develop a foldable and inflatable back clip for underground mining to enhance the protection of personal safety of operators and reduce their own burden. Utility Model Content
[0003] The utility model aims to provide a foldable inflatable back clip for underground mines, which has the advantages of wear resistance, moisture absorption, easy wearing, anti-impact and the like, thus ensuring the personal safety of underground mine workers.
[0004] To achieve the above purpose, the utility model provides the following solutions:
[0005] The utility model provides a foldable inflatable back clip for underground mine protection, comprising a nylon inner clip, an external air bag, a PVC frame and Velcro, wherein the nylon inner clip is located at the innermost side of the foldable inflatable back clip for underground mine protection of the utility model; the external air bag is fitted on the outer side of the nylon inner clip, and is provided with an inflation hole and a connecting port for overall inflation and deflation; the PVC frame is composed of 4-5 PVC plates connected by nylon ropes; the Velcro is fixed to the back of the foldable inflatable back clip for underground mine protection, and is used to adjust the tightness of the foldable inflatable back clip for underground mine protection; the waist of the foldable inflatable back clip for underground mine protection is not sewn, so it can be quickly put on.
[0006] Preferably, the innermost side of the nylon inner clip is made of non-toxic, lightweight, moisture-absorbing and wear-resistant nylon cloth;
[0007] Preferably, the external airbag is provided with a connecting port at the chest position to facilitate folding and storage after deflation;
[0008] Preferably, the PVC skeleton simulates the structure of the human spine to make the human body more comfortable;
[0009] Preferably, the Velcro at the outermost portion of the back clip can be adjusted in tightness and fixed according to the user's body shape.
[0010] Compared with the prior art, the utility model has achieved the following technical effects:
[0011] The utility model arranges nylon at the innermost side of the back clip and wraps the outer side with an air bag, thereby greatly improving the anti-collision effect; and adopts a PVC skeleton structure to simulate the human spine structure, so that the staff can feel more comfortable and light after wearing it; the Velcro on the outermost side of the back clip can adjust the tightness and fix it according to the body shape of the user.
[0012] The utility model provides a foldable inflatable back clip for underground mine protection. The innermost side of the back clip uses nylon cloth, and the outer side is equipped with an air bag that can significantly improve the impact resistance. The skeleton structure made of PVC material simulates the human spine, providing a more comfortable and light wearing experience for underground workers. In addition, the outermost layer of the back clip is equipped with Velcro that can be adjusted according to the wearer's body shape to facilitate personalized adjustment of tightness and fixation. This design not only takes safety into consideration, but also takes into account wearing comfort and practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0021] In this application, unless otherwise clearly specified and limited, the terms "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0022] See also Figure 1 As shown, a foldable inflatable back clip for underground mine protection includes a nylon inner clip 1, an external air bag 2, a PVC frame 3 and a Velcro 4. The nylon inner clip is built into the innermost part of the foldable inflatable back clip for underground mine protection. The nylon material has the advantages of being non-toxic, light, having excellent mechanical strength, moisture absorption and wear resistance, and good corrosion resistance. The external air bag 2 is on the outer side of the nylon inner clip 1, fits the nylon inner clip 1, and has an inflation hole 22 at the lower end for easy inflation and deflation. A connecting port 23 is also provided at the chest position for easy folding and storage after deflation. The PVC frame 3 is composed of 4-5 PVC plates 31 connected by nylon ropes 32, forming a back protection product. The Velcro 4 plays a role in adjusting the tightness and fixing at the outermost part of the back clip, and can perfectly fit the individual's body shape by adjusting the tightness. The waist of the foldable inflatable back clip for underground mine protection is not sewn, so it can be quickly put on.
[0023] See also Figure 2 As shown, a schematic diagram of the innermost nylon inner clip of a foldable inflatable back clip for underground mine protection has the characteristics of wear resistance, moisture absorption and heat absorption; see Figure 3-4 As shown, an inflation hole 22 is provided at the lower end of the external airbag 2, and inflation preparation is performed before use. After use, the inflation hole 22 can be opened to deflate the air. In addition, due to the design of a connecting port 23 at the chest position, the inflation and deflation speed can be accelerated. A PVC frame 3 is provided in the middle position of the rear part of the external airbag 2. The PVC frame 3 is composed of PVC plates 31 connected by nylon ropes 32 to simulate the structure of the human spine. It is more comfortable and light during operation. Since the middle of the PVC frame is connected by nylon ropes, it is easy to fold and store after use and deflation.
