Description

Technical Field

[0001] This utility model relates to the field of hose cover technology, and in particular to a hose cover confined space rescue device. Background Technology

[0002] A hose cap is an interface sealing component used with fire hoses or fluid conveying hoses. Its core function is to seal the ends of the hose or unused interfaces to prevent internal fluid leakage and external impurities from entering, while protecting the hose interfaces from damage.

[0003] The operation of existing caps mostly relies on threaded engagement and multi-clamp unlocking, and some require the assistance of tools such as wrenches. In emergency rescue scenarios, the cumbersome operation steps can delay the establishment of oxygen supply channels and affect the timeliness of rescue. In addition, although a few improved caps have added external operating parts, they are not equipped with reliable limiting structures. During the process of water hose handling and joint connection, the operating parts are prone to accidental displacement due to vibration and collision, resulting in oxygen leakage or abnormal flow, which can disrupt the stability of oxygen supply.

[0004] Therefore, it is necessary to provide a new confined space rescue device with a water hose cover to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a water hose cover confined space rescue device.

[0006] This utility model provides a confined space rescue device with a hose cover, which includes: a cover, a ring body, a connector, and a snap-fit ​​mechanism. A groove is provided on the upper surface of the cover. One end of the snap-fit ​​mechanism is fixedly connected to the inner wall of the groove on the upper surface of the cover. One side of the ring body is fixedly connected to the inner wall of the cover. One side of the connector is movably connected to one side of the cover.

[0007] The ring body includes a fixed ring, a gear ring, a lever plate, and a connecting mechanism. The two ends of the fixed ring are fixedly connected to the two sides of the inner wall of the ring body, respectively. The outer surface of the gear ring is rotatably connected to the inner wall of the ring body. One end of the lever plate is fixedly connected to the outer surface of the gear ring. The surface of the lever plate is rotatably connected to the inner wall of the sliding groove opened on the surface of the ring body. The surface of the lever plate is rotatably connected to the inner wall of the moving groove opened on the surface of the end cap. One side of the connecting mechanism is rotatably connected to the inner wall of the gear ring.

[0008] Preferably, the connecting mechanism includes multiple gears and multiple tooth blocks. One side of each gear is rotatably connected to the inner wall of the ring, the surfaces of the multiple gears mesh with the inner side of the gear ring, the surfaces of the multiple tooth blocks mesh with the surfaces of the multiple gears, and the surfaces of the multiple tooth blocks are slidably connected to the inner wall of the through hole opened on the surface of the fixed ring.

[0009] Preferably, the snap-fit ​​mechanism includes a pull plate, an elastic element, and a plug rod. The surface of the pull plate is slidably connected to the inner wall of the groove opened on the upper surface of the cover. The bottom of the pull plate is fixedly connected to the top of the elastic element. The bottom of the elastic element is fixedly connected to the bottom wall of the groove. The top of the plug rod is fixedly connected to the bottom of the pull plate. The surface of the plug rod is slidably connected to the inner wall of the through hole opened on the bottom wall of the groove. The bottom of the plug rod is slidably connected to the inner wall of the through hole opened on the surface of the push plate.

[0010] Preferably, the elastic element is a spring, which is sleeved on the outer surface of the insert rod, with the top of the spring fixedly connected to the bottom of the pull plate and the bottom of the spring fixedly connected to the bottom wall of the slide groove.

[0011] Preferably, the connector includes an inner ring, one end of which is fixedly connected to the inner wall of the connector, and multiple slots are formed on the outer surface of the inner ring, with the multiple slots slidably connected to one end of multiple tooth blocks.

[0012] Preferably, the top of the cover is provided with a connecting pipe, and one end of the connecting rod is fixedly connected to the inner wall of the through hole opened on the top of the cover.

[0013] Compared with related technologies, the confined space rescue device with a water hose cover provided by this utility model has the following beneficial effects:

[0014] 1. The cap and connector are aligned and rotated to achieve initial positioning and sealing. The rotating plate drives the gear ring to rotate, which in turn drives multiple gears to rotate. This causes multiple racks to move within the through holes on the surface of the fixing ring and engage with multiple slots on the inner ring surface. No additional tools such as wrenches are needed to quickly and securely seal the cap and connector, significantly shortening the time required to establish the oxygen supply channel and improving rescue efficiency. At the same time, it ensures that the moving distance and engagement torque of each rack are consistent during the fixing process, guaranteeing the reliability of the fixation and preventing damage to individual components due to uneven stress.

[0015] 2. By pulling the pull plate, the insertion rod moves upward. When the lever moves below the insertion rod, release the pull plate. The spring drives the insertion rod to move downward and abut against the inner wall of the through hole on the lever surface, thus quickly completing the limit fixation or unlocking of the lever. This effectively prevents the lever from accidentally shifting due to vibration or collision during water hose handling, connector docking, etc., and avoids abnormal oxygen flow or leakage.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1-5 ,in, Figure 1 This is a schematic diagram of a preferred embodiment of a confined space rescue device with a hose cover provided by this utility model; Figure 2 This is a bottom view of the cover shown in this utility model; Figure 3 This is a side view of the snap-fit ​​mechanism shown in this utility model; Figure 4 This is a cross-sectional view of the annular body shown in this utility model; Figure 5 This is a side view of the connector shown in this utility model.

[0024] In the specific implementation process, such as Figure 1-5 As shown, it includes: 1. a cap 1, a ring 3, a connector 5 and a snap-fit ​​mechanism. A groove 103 is provided on the upper surface of the cap 1. One end of the snap-fit ​​mechanism is fixedly connected to the inner wall of the groove 103 on the upper surface of the cap 1. One side of the ring 3 is fixedly connected to the inner wall of the cap 1. One side of the connector 5 is movably connected to one side of the cap 1.

[0025] The ring body 3 includes a fixed ring 302, a gear ring 303, a lever plate 304, and a connecting mechanism. The two ends of the fixed ring 302 are fixedly connected to the two sides of the inner wall of the ring body 3, respectively. The outer surface of the gear ring 303 is rotatably connected to the inner wall of the ring body 3. One end of the lever plate 304 is fixedly connected to the outer surface of the gear ring 303. The surface of the lever plate 304 is rotatably connected to the inner wall of the sliding groove 301 opened on the surface of the ring body 3. The surface of the lever plate 304 is rotatably connected to the inner wall of the moving groove 104 opened on the surface of the cover 1. One side of the connecting mechanism is rotatably connected to the inner wall of the gear ring 303.

[0026] The connecting mechanism includes multiple gears 305 and multiple tooth blocks 306. One side of each gear 305 is rotatably connected to the inner wall of the ring 3. The surfaces of the gears 305 mesh with the inner side of the gear ring 303. The surfaces of the tooth blocks 306 mesh with the surfaces of the gears 305. The surfaces of the tooth blocks 306 are slidably connected to the inner wall of the through hole on the surface of the fixed ring 302. Rotating the lever 304 drives the gear ring 303 to rotate, which in turn drives the multiple gears 305 to rotate. This causes the multiple racks to move within the through hole on the surface of the fixed ring 302 and abut against and fix with the multiple slots 502 on the surface of the inner ring 501. Without the need for wrenches or other additional tools, the sealing of the cap 1 and the connector 5 can be quickly completed, which greatly shortens the time for establishing the oxygen supply channel and improves the efficiency of rescue.

[0027] The locking mechanism includes a pull plate 201, an elastic element, and a plug rod 203. The surface of the pull plate 201 is slidably connected to the inner wall of the groove 103 opened on the upper surface of the end cap 1. The bottom of the pull plate 201 is fixedly connected to the top of the elastic element, and the bottom of the elastic element is fixedly connected to the bottom wall of the groove 103. The top of the plug rod 203 is fixedly connected to the bottom of the pull plate 201. The surface of the plug rod 203 is slidably connected to the inner wall of the through hole opened on the bottom wall of the groove 103. The bottom of the plug rod 203 is slidably connected to the inner wall of the through hole opened on the surface of the lever plate 304. By pulling the pull plate 201, the plug rod 203 moves upward. When the lever plate 304 moves below the plug rod 203, the pull plate 201 is released. The spring 202 drives the plug rod 203 to move downward and abut against the inner wall of the through hole on the surface of the lever, thus quickly completing the limiting and fixing or unlocking of the lever. This effectively prevents the lever from accidentally shifting due to vibration or collision during water hose handling, connector 5 docking, etc.

[0028] The elastic element is spring 202, which is sleeved on the outer surface of the insert rod 203. The top of spring 202 is fixedly connected to the bottom of pull plate 201, and the bottom of spring 202 is fixedly connected to the bottom wall of slide groove 103.

[0029] The connector 5 includes an inner ring 501, one end of which is fixedly connected to the inner wall of the connector 5. Multiple slots 502 are opened on the outer surface of the inner ring 501. The multiple slots 502 are slidably connected to one end of multiple tooth blocks 306. A sealing gasket is provided on the surface of the inner ring 501.

[0030] The top of the cap 1 is provided with a connecting pipe 102. One end of the connecting rod is fixedly connected to the inner wall of the through hole opened on the top of the cap 1. There are two fixed connections inside the cap 1 for connecting to the connector 5. The other end of the connecting pipe 102 is connected to the gas tank.

[0031] The working principle provided by this utility model is as follows:

[0032] By aligning the cap 1 with the connector 5 and rotating them, a preliminary limiting seal is achieved. Rotating the lever 304 drives the gear ring 303 to rotate, simultaneously rotating multiple gears 305. This causes multiple racks to move within the through-holes on the surface of the fixing ring 302 and abut against multiple slots 502 on the surface of the inner ring 501. Without the need for wrenches or other additional tools, the cap 1 and connector 5 are quickly and securely fixed, significantly shortening the time required to establish an oxygen supply channel and improving rescue efficiency. Simultaneously, it ensures that each gear block 306 moves a certain distance and abuts during the fixing process. Consistent torque ensures reliable fixation and prevents damage to individual components due to uneven force. Pulling the pull plate 201 moves the insertion rod 203 upward. When the lever plate 304 moves below the insertion rod 203, the pull plate 201 is released, and the spring 202 drives the insertion rod 203 downward to abut against the inner wall of the through hole on the lever surface, thus quickly completing the limit fixation or unlocking of the lever. This effectively prevents the lever from accidentally shifting due to vibration or collision during water hose handling, connector 5 docking, etc., and avoids abnormal oxygen flow or leakage.
