Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-rescue device technology, and more specifically, to a self-rescue device with an adjustable belt mechanism. Background Technology
[0002] A compressed oxygen self-rescue device is a self-rescue and escape device that uses high-pressure compressed oxygen as its oxygen source. It is mainly used in coal mines, firefighting, and other fields when toxic or harmful gas leaks or oxygen deficiency and asphyxiation occur in the work environment. Personnel on site can escape the disaster area and save themselves by wearing the compressed oxygen self-rescue device. The principle of an isolated compressed oxygen self-rescue device is that in the event of a coal mine accident, opening the cylinder valve allows high-pressure oxygen to be reduced to normal atmospheric pressure by a pressure reducer, and then flows out through the pressure reducer's constant flow port into the breathing bag for breathing. The compressed oxygen self-rescue device includes a breathing bag, an oxygen cylinder, and calcium hydroxide for absorbing carbon dioxide. The calcium hydroxide is generally located in the device's chemical chamber. In related technologies, the user exhales into the breathing bag through a mouthpiece connected to it. The exhaled gas diffuses from the breathing bag into the calcium hydroxide in the chemical chamber, allowing the calcium hydroxide to absorb the carbon dioxide in the gas.
[0003] In fields such as coal mining, miners and other workers need to store self-rescue devices in charging cabinets (miner's lamps). Due to the limited space inside the charging cabinet, and the need to store miner's lamps, self-rescue devices, and personal belongings, the storage space for some self-rescue devices is limited and quite cramped. Some existing self-rescue devices have waist buckles for wearing belts, which increases the thickness of the self-rescue device, making it difficult to put or take out the self-rescue device into the charging cabinet and prone to getting stuck. In addition, some existing self-rescue devices have belts that can only be tied around the waist, which is a single way of wearing them and cannot meet the needs of different wearing methods in different scenarios, resulting in a poor user experience.

Detailed Implementation
[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0029] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.
[0030] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
[0031] See Figures 1-12This utility model provides a self-rescue device with an adjustable belt mechanism, comprising: a body 1, on which a waist buckle 2 and an adjustable belt mechanism are provided. The waist buckle 2 is hinged to the body 1. The adjustable belt mechanism includes an adjustable buckle 3 and a rope 4. The adjustable buckle 3 is threaded onto the body 1, and the rope 4 is threaded onto the adjustable buckle 3. The adjustable buckle 3 can be adjusted and self-positioned along the extension direction of the rope 4 under external force. A hinge block 5 for hinged waist buckle 2 is provided on one side of the body 1. A placement plane 101 is provided at the bottom of the body 1. The waist buckle 2 includes an integrally formed hinge shaft 21 and a shaft-shaped buckle body 22. The connecting shaft 21 is hinged to the hinge block 5. The first axis 221 of the shaft-shaped buckle body 22 is parallel to and does not coincide with the second axis 211 of the hinge shaft 21. The second axis 211 is the axis of rotation when the hinge shaft 21 rotates, and the axis of rotation is perpendicular to the placement plane 101. This utility model has a self-rescue device with an adjustable belt mechanism. The waist buckle can rotate and retract, which can reduce the thickness of the self-rescue device (i.e., the Y-axis dimension) after retraction, making it easier to put into and take out of narrow spaces. Through the adjustable buckle, the user can easily adjust the position of the rope according to the needs of wearing a back strap, neck strap, and waist belt.
[0032] See Figures 1-5 Two hinge shafts 21 are provided, each connected to one end of the shaft-shaped buckle body 22, and the two hinge shafts 21 are located on the same straight line; two hinge blocks 5 are provided, with each hinge shaft 21 and hinge block 5 corresponding to each other for hinge connection; the body 1 includes an upper cover 11 and a lower shell 12, and the hinge blocks 5 include a first hinge block 51 and a second hinge block 52, with the first hinge block 51 located on the upper cover 11 and the second hinge block 52 located on the lower shell 12; the waist buckle 2 is easy to install, and is assembled with the upper cover 11 and the lower shell 12 to achieve the installation of the waist buckle 2 and the body; a movable lock 13 is provided between the upper cover 11 and the lower shell 12, and the upper cover 11 and the lower shell 12 can be locked and unlocked by the movable lock 13. After locking, the top cover 11 can be easily removed for operation; the hinge block 5 is provided with a hinge hole 501, and the hinge shaft 21 is rotatably inserted into the hinge hole 501. The waist buckle 2 is easy to assemble, has a simple structure, and low production cost; the body 1 is provided with a mounting hole 102 for inserting the adjustment buckle 3. The mounting hole 102 is a waist-shaped hole, and the adjustment buckle 3 can slide and rotate at the waist-shaped hole to adjust to the appropriate position, thereby avoiding occupying too much lateral space (i.e., X-axis space) when storing, so as to facilitate placement and retrieval; a bending part 23 is provided between the hinge shaft 21 and the shaft-shaped buckle body 22. The bending part 23 makes the first axis 221 of the shaft-shaped buckle body 22 parallel and non-coincident with the second axis 211 of the hinge shaft 21.
[0033] See Figure 1 , Figure 7 , Figure 8 and Figure 9When the waist buckle 2 rotates, it has an extended state and an inward state. In the extended state, it is convenient for the user to put on the waist belt inside the waist buckle 2, and in the inward state, it is convenient to store. In the extended state, the distance between the shaft-shaped buckle body 22 and the main body 1 is the first gap L, which is the self-rescue device when in use. In the inward state, the distance between the shaft-shaped buckle body 22 and the main body 1 is the second gap M. The first gap L is greater than the second gap M, so that the thickness of the self-rescue device in the inward state is smaller than that in the extended state, making it easier to put into and take out of narrow spaces. After the waist buckle 2 in the extended state is rotated 90 degrees, it coincides with the waist buckle 2 in the inward state, making it easy to operate.
[0034] See Figure 1 , Figure 6 , Figure 10 , Figure 11 and Figure 12 There are two adjusting buckles 3, and the two ends of the rope 4 are respectively threaded through the two adjusting buckles 3. The adjusting buckle 3 includes a buckle frame 31 and a rod 32 slidably disposed on the buckle frame 31. The rod 32 divides the inner frame of the buckle frame 31 into two frame openings, and the edge of one frame opening is threaded onto the main body 1. The two ends of the rod 32 are respectively provided with sliding collars 321 for slidingly fitting onto the buckle frame 31. The frame opening includes a first frame opening 311 and a second frame opening 312. The rope 4 enters from the first side of the first frame opening 311, passes around the rod 32, and exits from the second side of the second frame opening 312. The first side and the second side are located on the same side of the adjusting buckle 3. The rope 4 is easy to thread and the adjustment operation is simple. There are two adjusting buckles 3, and the two ends of the rope 4 are respectively threaded through the two adjusting buckles 3. The position of the rope can be adjusted according to the needs to meet the wearing and use requirements of a back strap, neck strap, and waist belt. The rope can be adjusted to the desired position. Figure 10 As shown, it can function as a carrying strap; the straps can be adjusted to... Figure 12 As shown, the upper part of the rope hangs around the neck as a neck strap 41, and the lower part of the rope is tied around the waist as a waist belt 42, making it easier for the self-rescue device to avoid excessive swaying when performing actions such as crawling. Specifically, when using the self-rescue device, first hang the neck strap around the neck, and then use the waist belts on both sides to raise the height of the self-rescue device for self-positioning. At the same time, it will not cause friction between the back straps and the neck, shortening the original back strap length to the neck strap length to realize the neck strap function. At this time, the waist belts that have been pulled out on both sides can be wrapped around the back and tied to realize the waist belt function, providing a good user experience.
[0035] This utility model relates to a self-rescue device with an adjustable belt mechanism. The waist buckle can rotate and retract inward, reducing the thickness of the self-rescue device and facilitating insertion and removal from confined spaces. The adjustable buckle allows users to adjust the position of the strap as needed, accommodating the use of a shoulder strap, neck strap, or waist belt. The waist buckle is easily installed and the device is simple in structure and low in production cost, achieved through assembly of the upper and lower shells. The mounting hole is an oblong shape, allowing the adjustable buckle to move along it to the appropriate position, minimizing the space occupied in the lateral direction (X-axis) during storage. In the extended position, the user can easily wear a waist belt inside the buckle; in the retracted position, it facilitates storage. The thickness of the self-rescue device in the retracted state is smaller than that in the extended state, making it easy to insert and remove from confined spaces.
[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
