Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water rescue equipment, in particular to a water rescue anti-slip lifesaving pull rod. BACKGROUND

[0002] The lifesaving pull rod is the most commonly used rescue tool in water rescue, and the end of the lifesaving pull rod is generally fixedly provided with a lifesaving ring. The lifesaving ring can provide a clear gripping point, so that the trapped person can more easily grab the pull rod in the water. The shape of the ring not only facilitates gripping, but also prevents the trapped person from slipping or being hit by water flow and dropping the pull rod, thereby improving the success rate of rescue. However, the lifesaving ring on the existing lifesaving pull rod cannot be quickly assembled, disassembled and replaced during actual rescue to adapt to different sizes of rescue space and different body types of trapped persons. In addition, for some trapped persons who are physically exhausted or unable to independently grip the lifesaving pull rod, the lifesaving ring cannot be deformed to form a barb to hook the clothing or other rescue equipment of the trapped person, helping the trapped person to escape from the dangerous area. SUMMARY

[0003] The purpose of the present application is to provide a water rescue anti-slip lifesaving pull rod to solve the problem of the lifesaving ring being unable to be conveniently replaced and deformed for better rescue as described in the background.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme: A water rescue anti-slip lifesaving pull rod, comprising: a pull rod body, a mounting bracket fixedly arranged on the pull rod body; A variable form rescue assembly installed on the mounting bracket for rescue; A convenient assembly and disassembly assembly installed on the pull rod body for fixing the variable form rescue assembly, and the convenient assembly and disassembly assembly can also drive the variable form rescue assembly to deform in cooperation with the variable form rescue assembly; A connection driving assembly installed on the pull rod body, connected with the convenient assembly and disassembly assembly to drive the convenient assembly and disassembly assembly to move, and the connection driving assembly is locked by the convenient assembly and disassembly assembly.

[0005] Further, the variable form rescue assembly comprises: a hinged bracket inserted into the mounting bracket and supported and positioned by the mounting bracket; Two half circular ring rods symmetrically hinged to the hinged bracket.

[0006] Further, the half circular ring rods are oppositely arranged to form a lifesaving ring, and the half circular ring rods are in the shape of a barb when rotating.

[0007] Further, the convenient installation and disassembly assembly comprises an adapter assembly bar movably mounted on the mounting bracket. A locking support plate is also mounted on the mounting bracket. A U-shaped moving frame is mounted on the adapter assembly bar.

[0008] Further, a first fixed pressing bar is fixedly arranged on the adapter assembly bar, and the hinged support frame is locked by the first fixed pressing bar, so that the hinged support frame is fixedly mounted on the mounting bracket.

[0009] Further, Z-shaped support plates are symmetrically fixed on both sides of the adapter assembly bar, the Z-shaped support plates are connected with the locking support plate, and the locking support plate is driven to move, and the semicircular ring rod is locked by the locking support plate.

[0010] Further, the locking support plate can also limit the driving U-shaped moving frame after unlocking the semicircular ring rod, so that the relative movement between the U-shaped moving frame and the adapter assembly bar occurs.

[0011] Further, the U-shaped moving frame movably connects an L-shaped support plate, the L-shaped support plate is fixedly provided with a deformation driving rod, and the semicircular ring rod is driven to rotate by the deformation driving rod.

[0012] Further, the connecting driving assembly comprises a threaded ring sleeve which is threadedly sleeved on the pull rod body. A interlocking movable ring is movably mounted on the threaded ring sleeve.

[0013] Further, the threaded ring sleeve is movably connected with the adapter assembly bar, and the adapter assembly bar is moved by the threaded ring sleeve.

[0014] Further, the interlocking movable ring is fixedly provided with a movable supporting rod, and the threaded ring sleeve is locked by cooperation of the movable supporting rod and the adapter assembly bar.

[0015] Compared with the prior art, the present application has the following advantages: 1. The semicircular ring rod formed by the pull rod body and the adapter assembly bar can be conveniently installed and disassembled, different sizes of the semicircular ring rod can be replaced according to the actual rescue process and the on-site environment, different sizes of the lifesaving circle can be formed, and the actual rescue demand can be met.

[0016] 2. When some trapped people are exhausted or unable to grab the lifesaving pull rod autonomously, the half-round ring rod can be rotated by moving the connecting assembly bar, so that the half-round ring rod becomes a barb, and the trapped people can be rescued by the barb-shaped half-round ring rod, helping them to escape from the dangerous area, which is practical and can adapt to different rescue situations.

[0017] 3. In addition, the lifesaving pull rod is simple to operate, and when the half-round ring rod is assembled and disassembled and the lifesaving circle is deformed, only the threaded ring sleeve needs to be rotated to complete the operation, which is convenient and fast.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0030] The present application provides a technical solution: As Figure 1 , Figure 2 and Figure 3As shown in the figure, a water area rescue anti-slip lifesaving pull rod, comprising: a pull rod body 1, a variable form rescue assembly, a convenient installation and disassembly assembly and a connection driving assembly, one end of the pull rod body 1 is welded and fixed with a limiting end disc 12, a supporting convex column 13 is welded and fixed on the limiting end disc 12, an installation support 14 is welded and fixed on the supporting convex column 13 away from the limiting end disc 12, the variable form rescue assembly is installed on the installation support 14 and supported by the installation support 14, so as to connect with the pull rod body 1 for rescue of the trapped person, the convenient installation and disassembly assembly is installed on the pull rod body 1 to fix the variable form rescue assembly, so as to ensure that the variable form rescue assembly can be stably and reliably installed on the pull rod body 1, thereby ensuring the smooth progress of the rescue work, and the convenient installation and disassembly assembly can also cooperate with the variable form rescue assembly to drive it to deform, that is, the variable form rescue assembly can be deformed from a lifesaving circle to an inverted hook, which is convenient for rescuing the trapped person who cannot hold the lifesaving pull rod by himself, the connection driving assembly is installed on the pull rod body 1 and connected with the convenient installation and disassembly assembly to drive the convenient installation and disassembly assembly to move, realizing the convenient installation and disassembly and deformation of the variable form rescue assembly, and the connection driving assembly is locked by the convenient installation and disassembly assembly to ensure the firmness of the installation of the variable form rescue assembly, in addition, the connection driving assembly can be limited by the limiting end disc 12.

[0031] As shown in the figure, Figure 2 , Figure 3 , Figure 6 and Figure 7 , the variable form rescue assembly comprises: a hinged support 2 and a semicircular ring rod 24, the hinged support 2 is inserted into the installation support 14 and positioned by the installation support 14, specifically, a limiting guide plate 16 is integrally formed in the inside of the installation support 14, a guide channel 23 is formed on the hinged support 2, when the hinged support 2 is inserted into the installation support 14, the limiting guide plate 16 is inserted into the guide channel 23, so that the hinged support 2 can be positioned under the cooperation of the limiting guide plate 16 and the guide channel 23, ensuring the accuracy of its installation, and two first through holes 15 are symmetrically formed on the bottom surface of the installation support 14.

[0032] The two semicircular rods 24 are symmetrically hinged on the hinge support frame 2 through the matching mounting blocks 26. The matching mounting slots 21 are symmetrically formed on the hinge support frame 2, and the matching mounting blocks 26 are hinged in the matching mounting slots 21. In addition, the second through holes 22 are formed in the bottom of the matching mounting slots 21, and the third through holes 27 are formed in the matching mounting blocks 26. When the hinge support frame 2 is inserted and mounted on the mounting support frame 14, the first through holes 15, the second through holes 22 and the third through holes 27 are vertically aligned, and the diameters of the first through holes 15, the second through holes 22 and the third through holes 27 are equal.

[0033] As shown in Figure 6 and Figure 8 , the two semicircular rods 24 are oppositely arranged to form a lifesaving circle. The lifesaving circle can provide a clear gripping point, so that the trapped person can more easily grab the pull rod in the water. The shape of the circle not only facilitates gripping, but also prevents the trapped person from dropping the pull rod due to slippery hands or water flow, thereby improving the success rate of rescue. When the semicircular rods 24 rotate, they become barbs, which can be used to hook the clothing of the trapped person or other lifesaving tools of the trapped person, take the trapped person away from the dangerous area, and help the trapped person escape.

[0034] As shown in Figure 2 , Figure 4 , Figure 9 and Figure 10 , the convenient mounting and dismounting assembly includes the connecting assembly bar 3, the locking support plate 4 and the U-shaped moving frame 5. The connecting assembly bar 3 is movably mounted on the mounting support frame 14. Specifically, the mounting vertical plate 17 is integrally formed on the mounting support frame 14, and the limiting channel 18 is formed on the mounting vertical plate 17. The inner wall of the limiting channel 18 is smooth and free of burrs. The support vertical plate 34 is welded and fixed on one end of the upper end of the connecting assembly bar 3. The first fixed pressing strip 341 is symmetrically welded and fixed on the upper end of the support vertical plate 34. The first fixed pressing strip 341 is inserted into the limiting channel 18 and in contact with the inner wall of the limiting channel 18. The connecting assembly bar 3 is supported by the cooperation of the limiting channel 18 and the first fixed pressing strip 341, and the first fixed pressing strip 341 can move in the limiting channel 18.

[0035] The locking support plate 4 is also mounted on the mounting support frame 14. Specifically, the locking insertion columns 41 are symmetrically fixed on the upper end of the locking support plate 4, and the locking insertion columns 41 are inserted into the first through holes 15.

[0036] The U-shaped moving frame 5 is installed on the connecting assembly strip 3. Specifically, a first supporting matching hole 51 is formed at the upper end of the U-shaped moving frame 5, a side wing protruding strip 35 is symmetrically welded and fixed at one end of the connecting assembly strip 3 close to the supporting vertical plate 34, and a first matching supporting rod 36 is welded and fixed on the side wing protruding strip 35. The surface of the first matching supporting rod 36 is smooth without burrs, and the first matching supporting rod 36 is inserted into the first supporting matching hole 51. The U-shaped moving frame 5 is supported through the cooperation of the first matching supporting rod 36 and the first supporting matching hole 51, and the U-shaped moving frame 5 can move along the first matching supporting rod 36.

[0037] When the first fixed pressing strip 341 moves synchronously with the connecting assembly strip 3, the articulated support frame 2 can be locked by the first fixed pressing strip 341. That is, when the first fixed pressing strip 341 moves in the direction of the pull rod body 1, the first fixed pressing strip 341 will press on the upper end surface of the articulated support frame 2, and the lower end surface of the articulated support frame 2 is in contact with the inner bottom surface of the mounting support frame 14. At the same time, the inner wall of the guide channel 23 is in contact with the limiting guide plate 16 on the mounting support frame 14. Thus, when the first fixed pressing strip 341 presses on the upper end surface of the articulated support frame 2, the articulated support frame 2 is fixedly installed on the mounting support frame 14, which can fully ensure the firmness and stability of the installation of the articulated support frame 2.

[0038] In addition, the second fixed pressing strip 342 is integrally formed on the first fixed pressing strip 341 away from the supporting vertical plate 34. When the two semicircular ring rods 24 form a lifesaving circle and are installed on the pull rod body 1, the first fixed pressing strip 341 moves to fix the articulated support frame 2, and at the same time, the first fixed pressing strip 341 drives the second fixed pressing strip 342 to move synchronously, so that the second fixed pressing strip 342 presses on the upper end surface of the matching mounting block 26. At this time, the lower end surface of the matching mounting block 26 is in contact with the inner bottom surface of the matching mounting groove 21. Thus, the semicircular ring rod 24 can be fixed through the cooperation of the second fixed pressing strip 342 and the matching mounting groove 21, so as to ensure the stability of the lifesaving circle.

[0039] The Z-shaped supporting plates 33 symmetrically arranged on both sides of the assembly strip 3 are welded and fixed, and are connected with the locking supporting plate 4 to drive the locking supporting plate 4 to move and lock the semicircular ring rod 24 through the locking supporting plate 4. Specifically, the first stable channel 331 is arranged at the upper end of the Z-shaped supporting plate 33, and the first stable channel 331 is connected with the displacement channel 332, and the second stable channel 333 is arranged at the lower end of the Z-shaped supporting plate 33, the displacement channel 332 is between the first stable channel 331 and the second stable channel 333, the lower end of the displacement channel 332 is in communication with the second stable channel 333, and the inner walls of the first stable channel 331, the displacement channel 332 and the second stable channel 333 are smooth without burrs, the support vertical plate 42 is symmetrically welded and fixed on the locking supporting plate 4, the displacement adjusting column 43 is welded and fixed on the inner end face of the support vertical plate 42, when the displacement adjusting column 43 is inserted into the first stable channel 331, the displacement adjusting column 43 is in contact with the inner wall of the first stable channel 331, at this time, the installation of the hinged support frame 2 is carried out, and in the installation process, the lock position inserting column 41 can be inserted into the third through hole 27 through the second through hole 22, and the lock position inserting column 41 is in contact with the inner wall of the third through hole 27, so that the semicircular ring rod 24 can be locked through the cooperation of the lock position inserting column 41 and the third through hole 27, so that the semicircular ring rod 24 cannot rotate, and the semicircular ring rod 24 can be doubly locked through the cooperation of the second fixed pressing strip 342, so as to further improve the stability of the lifesaving circle, and when the displacement adjusting column 43 moves relative to the displacement channel 332 and the second stable channel 333, the displacement adjusting column 43 is in contact with the inner walls of the displacement channel 332 and the second stable channel 333.

[0040] When the assembly strip 3 moves so that the displacement adjusting column 43 is inserted into the second stable channel 333 from the displacement channel 332, the displacement adjusting column 43 will move downward under the action of the displacement channel 332, thereby driving the locking supporting plate 4 to move downward, and the lock position inserting column 41 on the locking supporting plate 4 will exit the third through hole 27 as the locking supporting plate 4 moves downward, and at this time, the second fixed pressing strip 342 will no longer press on the cooperation mounting block 26, so that the semicircular ring rod 24 is in an unlocked state, and the lower end of the U-shaped moving frame 5 is inserted into the second stable channel 333, after the locking supporting plate 4 unlocks the semicircular ring rod 24, the displacement adjusting column 43 is in the second stable channel 333, which will be in contact with the U-shaped moving frame 5 to limit the U-shaped moving frame 5, and the U-shaped moving frame 5 moves relative to the assembly strip 3 as the assembly strip 3 moves.

[0041] The U-shaped moving frame 5 is hinged with a matching linkage rod 52, the upper end of the matching linkage rod 52 is hinged with an L-shaped supporting plate 53, the second supporting matching hole 54 is formed on the L-shaped supporting plate 53, the second matching supporting rod 37 is welded and fixed on the upper end of the side wing protruding strip 35, the second matching supporting rod 37 is matched with the second supporting matching hole 54, the L-shaped supporting plate 53 is limited through the matching of the two, and the deforming driving rod 55 is welded and fixed on the L-shaped supporting plate 53.

[0042] As shown in Figure 6 , the plug-in channel 25 is formed on one end of the semi-circular ring rod 24 close to the matching mounting block 26, and the inner wall of the plug-in channel 25 is smooth without burrs.

[0043] When the second fixed pressing strip 342 is pressed on the matching mounting block 26, the deforming driving rod 55 is plugged in the plug-in channel 25 at this time, and the deforming driving rod 55 is in contact with the inner wall of the plug-in channel 25. When the semi-circular ring rod 24 is in the unlocked state, and the relative movement between the U-shaped moving frame 5 and the linking assembly strip 3 occurs, the distance between the U-shaped moving frame 5 and the L-shaped supporting plate 53 becomes smaller, the L-shaped supporting plate 53 is moved upward under the action of the matching linkage rod 52, so that the deforming driving rod 55 is also moved upward, so that the semi-circular ring rod 24 is rotated upward under the action of the deforming driving rod 55, and the semi-circular ring rod 24 is driven to rotate by the deforming driving rod 55, so that the semi-circular ring rod 24 forms an inverted hook.

[0044] As shown in Figure 4 , Figure 5 and Figure 10 , the connecting driving assembly includes a threaded ring 6 and a interlocking movable ring 65, the threaded ring 6 is threadedly sleeved on the pull rod body 1, specifically, the matching thread 11 is arranged on one end of the pull rod body 1 close to the limiting end disc 12, the threaded ring 6 is threadedly matched with the matching thread 11, and the limiting end disc 12 can limit the threaded ring 6 when the threaded ring 6 is in contact with the limiting end disc 12, so as to avoid separation of the threaded ring 6 from the pull rod body 1.

[0045] The interlocking movable ring 65 is movably installed on the threaded ring 6. Specifically, a connecting support column 62 is welded and fixed on the threaded ring 6, a matching support ring 63 is welded and fixed on the end of the connecting support column 62 away from the threaded ring 6, the matching support ring 63 is symmetrically provided with movable through holes 64, the interlocking movable ring 65 is symmetrically and integrally provided with two protruding support blocks 66, the protruding support blocks 66 are welded and fixed with movable support rods 67, the movable support rods 67 are inserted into the movable through holes 64, the movable support rods 67 are sleeved with connecting springs 68, one end of the connecting springs 68 is welded and fixed on the protruding support blocks 66 of the interlocking movable ring 65, the other end is welded and fixed on the matching support ring 63, in addition, a limiting end block 69 is welded and fixed on one of the movable support rods 67, the limiting end block 69 limits the interlocking movable ring 65, avoiding separation of the interlocking movable ring 65 from the matching support ring 63 under excessive external force.

[0046] The threaded ring 6 is movably connected with the connecting assembly strip 3, the threaded ring 6 drives the connecting assembly strip 3 to move, specifically, the connecting assembly strip 3 is integrally provided with a linkage insertion block 31 at one end away from the support vertical plate 34, the threaded ring 6 is provided with a driving ring groove 61, the linkage insertion block 31 is inserted into the driving ring groove 61, the linkage insertion block 31 is in contact with the inner wall of the driving ring groove 61, and the threaded ring 6 can rotate relative to the linkage insertion block 31, so that the threaded ring 6 can drive the connecting assembly strip 3 to move synchronously when moving.

[0047] The connecting assembly strip 3 is provided with a lock ring insertion cavity 32 at one end close to the interlocking movable ring 65, when the movable support rod 67 without the limiting end block 69 is inserted into the lock ring insertion cavity 32, the threaded ring 6 can be locked by the cooperation of the movable support rod 67 and the lock ring insertion cavity 32, ensuring the stability of the lifesaving circle shape and the barb shape.

[0048] When the rod body 1 is not installed with the articulated support frame 2, the threaded ring sleeve 6 is in the position in contact with the limiting end disc 12, and when the articulated support frame 2 is installed, the semicircular ring rod 24 forms a lifesaving circle, and then the articulated support frame 2 is inserted into the mounting support frame 14 and positioned through the cooperation of the guide channel 23 and the limiting guide plate 16. When the articulated support frame 2 is inserted, the locking plug-in column 41 is also inserted into the third through hole 27, thereby fixing the semicircular ring rod 24 and preventing it from rotating. Then pull the interlocking movable ring 65 to make the movable supporting rod 67 exit the lock ring insertion cavity 32, so that the threaded ring sleeve 6 is in the unlocked state. Then rotate the interlocking movable ring 65 to drive the threaded ring sleeve 6 to rotate synchronously, so that the threaded ring sleeve 6 moves away from the limiting end disc 12 under the action of the thread. This can drive the connection assembly strip 3 to move synchronously, and the movement of the connection assembly strip 3 can press the first fixed pressing strip 341 on the articulated support frame 2 and the second fixed pressing strip 342 on the cooperating mounting block 26, thereby fixing the articulated support frame 2 and the semicircular ring rod 24. The installation of the articulated support frame 2 is very convenient, and the installation and removal of the articulated support frame 2 is very simple and fast. Therefore, different sizes of semicircular ring rods 24 can be replaced according to the actual rescue situation to form lifesaving circles of different sizes for use. After the articulated support frame 2 is fixed, the interlocking movable ring 65 is released to insert the movable supporting rod 67 into the lock ring insertion cavity 32 again. Since the connection assembly strip 3 cannot rotate, the interlocking movable ring 65 is limited when the movable supporting rod 67 is inserted into the lock ring insertion cavity 32, so that the threaded ring sleeve 6 cannot rotate, thereby achieving the locking of the threaded ring sleeve 6. This can ensure the stability of the installation of the articulated support frame 2. At this time, the displacement adjusting column 43 is still in the first stable channel 331, so that the semicircular ring rod 24 is double-locked. At this time, the deformed driving rod 55 is inserted into the insertion channel 25. When it needs to be deformed into an inverted hook shape, pull the interlocking movable ring 65 to separate the movable supporting rod 67 from the lock ring insertion cavity 32, and rotate the interlocking movable ring 65 again to make the threaded ring sleeve 6 continue to move away from the limiting end disc 12. This will make the displacement adjusting column 43 pass through the displacement channel 332 and be in the second stable channel 333, thereby driving the locking plug-in column 41 to move down and exit the third through hole 27 and be in the second through hole 22, which will not affect the rotation of the cooperating mounting block 26. At the same time, the second fixed pressing strip 342 passes through the cooperating mounting block 26, so that the semicircular ring rod 24 is in the unlocked state. With the continuous movement of the connection assembly strip 3, the displacement adjusting column 43 contacts the U-shaped moving frame 5 and is limited, so that the U-shaped moving frame 5 moves relative to the connection assembly strip 3, the distance between the U-shaped moving frame 5 and the L-shaped supporting plate 53 becomes smaller, and the L-shaped supporting plate 53 is driven to move up under the action of the cooperating linkage rod 52, thereby driving the deformed driving rod 55 to move up,Thus, the half-ring lever 24 is driven to rotate upward to form an inverted hook shape under the cooperation of the deformation driving lever 55 and the insertion channel 25, and then the interlocking movable ring 65 is released to enable the movable supporting lever 67 to be inserted into the lock ring insertion cavity 32, so that the utility of the lifesaving pull lever is stronger, the functionality is stronger, different rescue situations can be adapted, and the use is more convenient.

[0049] While embodiments of the present application have been shown and described, it is to be understood that the embodiments described are merely divergences of the principles and spirit of the present application and that numerous modifications, substitutions, replacements and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
