Description

Technical Field

[0001] The invention belongs to the technical field of rescue equipment, and in particular relates to a protective device for emergency rescue. Background Art

[0002] After an emergency occurs, it is necessary to organize corresponding personnel for rescue. In order to reduce the physical injuries of rescuers during the rescue process, rescuers usually need to wear protective equipment to protect themselves. In the process of urban emergency rescue, some high-rise operations are usually involved, and existing protective devices are usually difficult to achieve high-altitude escape for rescuers. For example, in high-rise rescue operations, rescuers sometimes encounter fires and cannot escape from the corridor. At this time, they usually need to escape from windows, but in the existing technology, protective devices cannot provide protection for personnel when escaping from high altitudes. During the high-rise escape process, personnel need to prepare ropes and bind the two ends of the rope to themselves and the windows respectively. People originally need to pull the ropes down to escape, but people are prone to hand fatigue during long-term holding of the ropes. If they accidentally let go, it is easy to cause accidents. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0033] Reference Figure 1-4 One embodiment of the present invention provides a protective device for emergency rescue, including a backpack 1, in which some corresponding rescue devices can be loaded. In addition, the device also includes:

[0034] The reel 2 and the drawstring 3 are movably arranged on the backpack 1. One end of the drawstring 3 is connected to the reel 2, and the other end is used to connect to the window when escaping, or to tie some objects such as hooks to connect to the window. When the reel 2 is in motion, it can retract and release the drawstring 3. Similarly, when the drawstring 3 is pulled, the reel 2 will move.

[0035] The deceleration component 4 is installed on the backpack 1 and is used to limit the moving speed of the winding part 2. The deceleration component 4 has an adjustment end 401. When a person holds the adjustment end 401 and pinches it, the speed limiting effect of the deceleration component 4 on the winding part 2 can be correspondingly released according to the pinching force.

[0036] When the present invention cooperates with rescue personnel to escape from high-rise buildings, one end of the pull rope 3 is connected to the window, and the person can be lowered down by carrying the backpack 1 on the body. Under normal circumstances, the reel 2 can no longer move on the backpack 1 under the action of the deceleration component 4. When the person pinches the adjustment end 401, the pull rope 3 is tightened due to the gravity of the person, and the reel 2 can move, and the pull rope 3 is pulled out from the reel 2 to realize the lifting and lowering of the person. When it is necessary to increase the lifting and lowering speed, the pinching force on the adjustment end 401 can be increased, so that the person can freely control the falling speed. Compared with the prior art, the present device does not need to excessively consume the physical strength of the person, thereby fully ensuring the safety of the person.

[0037] Further, see Figure 4 In the present invention, the winding portion 2 is a circular structure, and a winding area 201 is constructed on its circumferential side. The drawstring 3 is connected to the inner side of the winding area 201. The winding portion 2 is rotatably arranged on the backpack 1. When the winding portion 2 rotates in two directions, the drawstring 3 can be wound up and released respectively.

[0038] Further, see Figure 1-4 In the present invention, the structure of the backpack 1 includes a first part and a second part 102 connected to each other. The first part 101 is used to fit the back and has a hard structure. The second part 102 is a soft structure and can be made of cotton cloth or leather. The roll-up part 2 is rotatably connected to the first part 101, and the hard structure can ensure the stability of the roll-up part 2 during rotation. In order to increase the practical function of the backpack 1, a detachable partition 7 is also provided in the backpack 1. The partition 7 cooperates with the first part 101 to form a cavity structure, and the roll-up part 2 is located therein, so that when other devices are loaded in the backpack 1, they will not affect each other with the roll-up part 2. The partition 7 can be installed on the first part 101 in a snap-on form for easy disassembly.

[0039] Further, see Figure 4 Regarding the rotation setting of the winding section 2, a plurality of rollers 5 are rotatably set on the first part 101, the winding section 2 is located between the plurality of rollers 5, and the peripheral side of the winding section 2 forms a roller 5 cooperation with the plurality of rollers 5, thereby achieving the effect of rotation installation on the first part 101. The plurality of rollers 5 are distributed on the peripheral side of the winding section 2 to support the winding section 2. This structure can effectively ensure the stability and firmness of the rotation installation of the winding section 2 on the first part 101.

[0040] Further, see Figure 5The deceleration component 4 includes a force spring 402, which is connected to the first part 101 and forms a resistance with the winding part 2. Through contact friction, the rotation process of the winding part 2 can be limited, thereby achieving the effect of deceleration and limiting the movement of the winding part 2.

[0041] Further, based on the above structure, continue to refer to Figure 5 A force plate 202 is also constructed on the winding part 2, one side of the force plate 202 is flush with one side of the winding part 2 and fits the first part 101, one end of the force spring 402 acts on the force plate 202 to achieve the effect of resisting the winding part 2. By applying force to the force plate 202, the contact friction between the end face of the winding part 2 and the first part 101 can be used to further increase the restriction effect on the winding part 2.

[0042] Further, see Figure 5 Regarding the working mode of the adjusting end 401, specifically, the deceleration assembly 4 also includes a resistance spring 403 and a telescopic cylinder 404, the resistance spring 403 is connected to the first part 101, the force spring 402 and the resistance spring 403 are connected through a connecting plate 6, the force spring 402 and the resistance spring 403 are in a compressed state under normal conditions, the telescopic cylinder 404 is connected between the first part 101 and the connecting plate 6, the adjusting end 401 is an inflatable part, and is connected to the telescopic cylinder 404, the adjusting end 401 can adopt a balloon structure, when the adjusting end 401 is pinched, air can be supplied to the telescopic cylinder 404 through the adjusting end 401, and when the telescopic cylinder 404 is extended, it pushes the connecting plate 6 away from the force-bearing plate 202, so that the compression state of the force spring 402 is relieved, thereby reducing the squeezing of the force-bearing plate 202, so as to reduce the restricting effect on the winding part 2.

[0043] Further, see Figure 3-4 as well as Figure 6-7 A protective shell 8 is fixedly provided on the first part 101, and a cutting knife 9 is slidably provided on the protective shell 8. A pushing end 10 is fixedly connected to the cutting knife 9, which is located outside the first part 101 so that people can hold and touch it. The cutting knife 9 can cut the pull rope 3 during its activity. A spring sheet is connected between the cutting knife 9 and the protective shell 8 to keep the cutting knife 9 away from the pull rope 3. During use, when a person reaches the ground, the cutting knife 9 can be moved by holding the pushing end 10, so that the pull rope 3 can be quickly cut off to release the pull rope 3 from binding the person, thereby increasing the use effect.

[0044] Further, see Figure 4 as well as Figure 6-7A rotating frame 11 is rotatably arranged on the first part 101, and the rotating frame 11 has at least a blocking end 11a and a limiting end 11b. A reset torsion spring is connected between the rotating frame 11 and the first part 101. In normal state, the rotating frame 11 rotates under the action of torque so that the blocking end 11a presses the pull rope 3, so that when the pull rope 3 is subjected to force, it will push the blocking end 11a in a straight state. At this time, the rotating frame 11 rotates to make the limiting end 11b and the cutting knife 9 engage with each other, so that the cutting knife 9 cannot move and cannot cut. This structure ensures that when the personnel are still in the process of hanging, the personnel accidentally touch the pushing end 10 and will not control the movement of the cutting knife 9, thereby increasing the safety effect; regarding the engaging state, a limiting hole is constructed on the cutting knife 9, and the limiting end 11b is directly inserted into the limiting hole when engaging with its engaging.

[0045] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
