[0025] Reference Figures 1 to 3, a safety protection device, including an inflatable component 100; a protective sleeve 200, used to accommodate a gas cylinder; a locking piece 310, connected to the inflatable component 100, and the locking piece 310 is used to lock the protective sleeve 200 to the inflatable component 100. The protective sleeve 200 can prevent the gas cylinder from bursting and injuring people when the fragments are exploded, and the locking piece 310 can lock the protective sleeve 200 when the gas cylinder is inflated to prevent the protective sleeve 200 from being separated by force to ensure safety. It can be understood that the gas cylinder refers to a gas cylinder with a one-way valve, and the one-way valve is installed at the mouth of the gas cylinder to prevent leakage when the gas cylinder is removed. It should be noted that the protective sleeve 200 can be cylindrical, square cylindrical or other shapes, and the protective sleeve 200 can be made of polyethylene fiber cloth, or steel or bronze alloy. It can be understood that the locking member 310 can be a locking block hinged on the inflatable component 100, the locking block includes a hinged end and a free end, and the locking block can rotate to allow the free end to clamp the external flange 210 of the protective sleeve 200. The locking member 310 can also be a top block driven by a cylinder or a hydraulic cylinder, and the top block fixes the protective sleeve 200 on the inflatable component 100.

[0026] Reference Figure 1 , an outer flange 210 is provided at one end of the protective sleeve 200 close to the inflatable component 100, and the locking member 310 is used to buckle the outer flange 210 of the protective sleeve 200. The outer flange 210 is provided to facilitate the locking member 310 to lock the protective sleeve 200, so as to facilitate the fixing of the protective sleeve 200. It is understandable that the outer flange 210 is arranged around the edge of the protective sleeve 200 and the outer flange 210 extends along the radial direction of the protective sleeve 200. It is understandable that the radial direction of the protective sleeve 200 refers to the extension direction perpendicular to the protective sleeve 200. It is understandable that the outer flange 210 can be continuous or discontinuous. The continuous outer flange 210 refers to one outer flange 210 arranged around the circumference of the protective sleeve 200, and the discontinuous outer flange 210 refers to multiple outer flanges 210 distributed around the circumference of the protective sleeve 200.

[0027] In some embodiments, the locking member 310 is rotatably connected to the inflatable component 100, and the locking member 310 is provided with a plurality of buckling portions 311. The outer flange 210 is provided with an escape opening 211 corresponding to the buckling portion 311. The buckling portion 311 and the escape opening 211 are provided to facilitate the installation and removal of the protective cover 200. It should be noted that the locking member 310 is annular, the inflatable core 110 is provided in the annular locking member 310, the buckling portion 311 is provided on the annular edge of the locking member 310 and the buckling portion 311 extends toward the center of the annular locking member 310, and the size of the escape opening 211 provided on the outer flange 210 is larger than the size of the buckling portion 311, so that the buckling portion 311 can pass through the escape opening 211. When in use, the protective sleeve 200 is connected to its external flange 210 and is placed close to the locking member 310, so that the pressing portion 311 on the locking member 310 passes through the avoidance opening 211 on the external flange 210, and then the locking member 310 is rotated to make the pressing portion 311 and the external flange 210 abut against each other.

[0028] In some embodiments, an elastic top block is provided in the locking member 310. When the locking member 310 is rotated and locked, the elastic top block pushes the protective sleeve 200 along the axis of the protective sleeve 200 in a direction away from the locking member 310, so that the external flange 210 of the protective sleeve 200 and the locking member 310 are locked more tightly.

[0029] In some embodiments, six pressing portions 311 are evenly distributed on the annular periphery of the locking member 310 .

[0030] In some embodiments, a limit block 120 is provided on the inflatable component 100, and a stop block 140 is provided on the lock member 310. The limit block 120 cooperates with the stop block 140 to limit the rotation angle of the lock member 310, so as to prevent the lock member 310 from rotating excessively, which makes it inconvenient to remove the protective cover 200. It can be understood that the limit block 120 on the inflatable component 100 is provided on the gas circuit connection block 130.

[0031] In some embodiments, the protective sleeve 200 includes a main body 230 and a cover 220, one end of the main body 230 is connected to the locking member 310, and the other end is detachably connected to the cover 220, and the cover 220 can reduce the frequent disassembly and assembly of the protective sleeve 200, thereby extending the service life of the safety protection device. It should be noted that the cover 220 can be connected to the end of the main body 230 away from the inflatable component 100 by threading, or can be connected to the end of the main body 230 away from the inflatable component 100 by interference. It can be understood that the interference connection is a connection achieved by using the interference fit between parts.

[0032] In some embodiments, a pressure relief hole 221 is provided on the protective sleeve 200 and / or the cover 220. The pressure relief hole 221 is used to release pressure when the gas cylinder in the protective sleeve 200 explodes to prevent the protective sleeve 200 from being shattered. It should be noted that there is at least one pressure relief hole 221, and the diameter of the pressure relief hole 221 is between 1 mm and 10 mm.

[0033] In some embodiments, the inflatable component 100 includes an air circuit connection block 130 and an inflatable core 110. One end of the inflatable core 110 is connected to the air circuit connection block 130, and the other end is used to connect to the gas cylinder. The air circuit connection block 130 is connected to an inflatable valve 132 and a pressure relief valve 133. The set air circuit connection block 130 can be used as an installation carrier for the inflatable core 110, the inflatable valve 132 and the pressure relief valve 133, so as to achieve centralized installation and reduce installation space. The set inflatable valve 132 and the pressure relief valve 133 can cooperate for inflation. It should be noted that the air circuit connection block 130 is also connected to an intake pressure gauge 131 and a gas cylinder pressure gauge 134. The intake pressure gauge 131 is used to detect the intake pressure, and the gas cylinder pressure gauge 134 is used to detect the gas cylinder pressure. It should be noted that when inflating, first connect the gas cylinder to the inflatable core 110, open the inflation valve 132, and close the pressure relief valve 133 to inflate the gas cylinder. At this time, the value of the gas cylinder pressure gauge 134 can be observed. When the value of the gas cylinder pressure gauge 134 reaches a predetermined value, close the inflation valve 132 and open the pressure relief valve 133. Since the gas cylinder itself has a one-way valve, the gas in the gas cylinder will not be lost, and the pressure relief valve 133 releases the residual air pressure inside the gas circuit to prevent the gas cylinder from bursting out due to the air pressure of the gas circuit when the gas cylinder is removed. It can be understood that the gas cylinder pressure gauge 134 detects the gas cylinder pressure by measuring the pressure at the mouth of the gas cylinder. When the gas cylinder is inflated, the gas cylinder belongs to an open space, and the gas cylinder pressure gauge 134 can detect the air pressure in the gas cylinder. It can be understood that the gas cylinder and the inflatable core 110 can be connected by threads or by snaps. It is understandable that the inflation component 100 further includes a high-pressure pump, which is connected to the gas circuit connection block 130 , and the high-pressure pump pressurizes the gas and delivers it to the gas circuit connection block 130 .

[0034] In some embodiments, the inflation component 100 may also be an inflation cylinder or an inflation gun.

[0035] In some embodiments, the inflatable core 110 is threadedly connected to the gas circuit connection block 130, and a tightening block 135 is also connected to the gas circuit connection block 130. The tightening block 135 is used to tighten the inflatable core 110 to prevent the inflatable core 110 from falling off. It should be noted that the tightening block 135 is threadedly connected to the gas circuit connection block 130, and when the tightening block 135 is rotated, the tightening block 135 pushes the inflatable core 110 downward to prevent the inflatable core 110 from falling off.

[0036] Reference Figure 3, and also includes a clamping mechanism 400, which is used to clamp the gas cylinder, making it convenient to connect the gas cylinder to the inflation core 110 when inflating the gas cylinder, and also convenient to remove the gas cylinder when the gas cylinder is fully inflated.

[0037] In some embodiments, the clamping mechanism 400 includes a clamping head 410 and a push rod 420. The clamping head 410 is connected to one end of the push rod 420 close to the inflatable assembly 100. The push rod 420 is connected to the protective sleeve 200 through an elastic member 430. The push rod 420 is used to drive the clamping head 410 to tighten the gas cylinder. The push rod 420 and the clamping head 410 have a simple structure and are easy to install and use. The elastic member 430 can also provide a pre-tightening force to keep the clamping mechanism 400 stable. It should be noted that a clamping opening is provided on the clamping head 410, and the clamping opening gradually decreases from the end close to the gas cylinder to the end away from the gas cylinder. When clamping the gas cylinder, the gas cylinder is tightened by the clamping head 410 to facilitate the operation of the gas cylinder.

[0038] In some embodiments, a knob 421 is connected to the push rod 420, and an anti-slip ridge 421a is provided on the knob 421. The gas cylinder is installed or removed by twisting the knob 421.

[0039] In some embodiments, the safety protection device is installed on a guide rail, that is, the safety protection device can slide along the extension direction of the guide rail. The guide rail can facilitate the movement of the safety protection device. When the gas cylinder needs to be installed, the safety protection device can be moved close to the gas cylinder, reducing the transportation distance of the gas cylinder, saving physical effort, and facilitating installation.

[0040] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
