[0028] Embodiment
[0029] Referring to Figures 1 - 5 , the present utility model provides a safety rope, including an annular rope body, and a first limiting member is arranged on the annular rope body; one end of the annular rope body forms a first buckle 300 under the action of the first limiting member; a first fixing member 900 is arranged on the annular rope body, and a first return spring 600 is arranged between the first limiting member and the first fixing member 900. One end of the first return spring 600 abuts against the first limiting member, and the other end abuts against the first fixing member 900. And a connecting rope 150 between the first limiting member and the first fixing member 900 is sleeved on the first return spring 600. The first fixing member 900 is used to adjust the positioning point so that the first return spring 600 is in a pre-tightened state.
[0030] In some embodiments, the first buckle 300 of the safety rope is used to connect with a high-pressure hose 100. By moving the first fixing member 900 away from the first buckle 300, the first buckle 300 becomes larger, so that the high-pressure hose 100 can be inserted into the first buckle 300; the first return spring 600 moves the first fixing member 900 away from the first fixing member 900, making the first buckle 300 smaller; in order to make the connection between the safety rope and the high-pressure hose 100 more firm, by adjusting the positioning point of the first fixing member 900 on the annular rope body, the position of the positioning point of the first fixing member 900 on the annular rope body can be adjusted according to the specification of the high-pressure hose 100 and the change of the requirement for the pre-tightening force, thereby ensuring that the first return spring 600 can provide sufficient pre-tightening force. When the high-pressure hose 100 falls off, the first buckle 300 can firmly sleeve on the high-pressure hose 100, thereby enabling the safety rope to effectively prevent the high-pressure hose 100 from flying out disorderly and ensuring the safety during the use of the high-pressure hose 100.
[0031] The adjustment positioning point of the first fixing member 900 on the annular rope body enables the size of the first buckle 300 to be adjusted according to actual needs, so that the first buckle 300 can be conveniently sleeved on the high-pressure hose 100; then the size of the first buckle 300 is adjusted again so that the first buckle 300 will not detach from the high-pressure hose 100.
[0032] The first fixing member 900 can move on the annular rope body, thereby compressing the first return spring 600 and making the first limiting member always tend to move towards the first lock 300. That is, the first limiting member has a tendency to make the first lock 300 shrink, so that the first lock 300 can be firmly fixed on the annular rope body.
[0033] In an alternative embodiment, the first limiting member is provided with two guiding holes, and the annular rope body is passed through each of the guiding holes; the first limiting member includes a first guiding clip 700 and / or a guiding gasket 800.

The guiding gasket 800 is arranged between the first return spring 600 and the first guiding clip 700. A guiding hole is provided on the guiding gasket 800. The first return spring 600 can better abut against the first guiding clip 700 through the guiding gasket 800, so that the first return spring 600 can better apply an elastic force to the first limiting member.
[0035] In an alternative embodiment, the first fixing member 900 is a U-shaped shackle; the first return spring 600 is a convex compression spring or a cylindrical compression spring.
[0036] A first limiting member is arranged on the annular rope body. Two guiding holes are arranged on the first limiting member. The annular rope body is passed through the guiding holes. The first limiting member can move on the annular rope body, thereby adjusting the size of the first lock 300.
[0037] The first fixing member 900 is a U-shaped shackle. The first fixing member 900 can fix two connecting ropes 150 together and can adjust its position on the connecting ropes 150; this enables the first fixing member 900 to better play a supporting role, making the first return spring 600 in a compressed state and the first return spring 600 making the first limiting member always maintain a tendency to move towards the high-pressure rubber hose 100, so that the first lock 300 maintains a shrinking movement tendency.
[0038] Since the first return spring 600 is sleeved on the connecting rope 150, the first return spring 600 always maintains linear expansion and contraction, that is, the first return spring 600 can better act on the first limiting member.
[0039] In an alternative embodiment, the second limiting member forms a second lock 400 at the other end of the annular rope body, and the first limiting member and the second limiting member make the annular rope body between the first limiting member and the second limiting member form two juxtaposed connecting ropes 150.

[0042] Two guiding holes are provided on the second limiting member, and the annular rope main body is threaded through each guiding hole. The second limiting member includes a second guiding clip 140 and / or a guiding gasket 800.
[0043] In some embodiments, the first limiting member and the second limiting member have similar structures. The second limiting member includes a second guiding clip 140 or a guiding gasket 800, or the second limiting member includes a second guiding clip 140 and a guiding gasket 800.
[0044] A guiding gasket 800 is provided between the second return spring 120 and the second guiding clip 140. The second fixing member 130 can fix the two connecting ropes 150 together and can adjust its position on the connecting ropes 150; this enables the second fixing member 130 to better play a supporting role, keeps the second return spring 120 in a compressed state, and the second return spring 120 makes the second guiding clip 140 always maintain a tendency to move towards the fixed object, so that the second buckle 400 maintains a tendency to shrink.
[0045] A second return spring 120 is provided between the second limiting member and the second fixing member 130. One end of the second return spring 120 abuts against the second limiting member, and the other end abuts against the second fixing member 130.

[0046] In an optional embodiment, a clamping sleeve 200 or a U-shaped shackle is provided between the first fixing member 900 and the second fixing member 130 to keep the two connecting ropes 150 side by side.
[0047] The head and tail of the safety rope are connected to form a looped rope body. The buckle sleeve 200 is arranged at the connection of the head and tail of the safety rope, providing effective protection for the connection of the head and tail of the safety rope, not only extending the service life but also maintaining the beauty of the steel wire rope. Moreover, it can hide the burrs of the steel wire rope at the connection of the head and tail of the safety rope, preventing the steel wire burrs from hurting people. And the length of the safety rope can be freely designed according to the site, with any length taken, and it is convenient to manufacture.
[0048] Refer to Figure 3 In an alternative embodiment, a guiding gasket 800 is arranged on one side of the first return spring 600 and / or the second return spring 120 close to the first limiting member.
[0049] A guiding gasket 800 is arranged on one side of the first return spring 600 or the second return spring 120 close to the first limiting member, or on one side of both the first return spring 600 and the second return spring 120 close to the first limiting member; in this way, the first return spring 600 can better contact the first limiting member, and the elastic force of the first return spring 600 can be better applied to the first limiting member.
[0050] A guiding gasket 800 is arranged between the second return spring 120 and the second fixing member 130; in this way, the second fixing member 130 can better support the second return spring 120 through the guiding gasket 800, and the elastic force of the second return spring 120 can be better applied to the second limiting member.
[0051] In an alternative embodiment, the second fixing member 130 is a U-shaped shackle; the second return spring 120 is a convex middle compression spring or a cylindrical compression spring.
[0052] Both the first fixing member 900 and the second fixing member 130 can be U-shaped shackles, and both the first return spring 600 and the second return spring 120 can be convex middle compression springs or cylindrical compression springs. As a preferred embodiment, both the first return spring 600 and the second return spring 120 are convex middle compression springs. The convex middle compression spring has a simple structure. After pre-tightening, the spring will effectively contact the joint of the looped rope body and the high-pressure rubber hose 100. After compression, it serves as an energy buffer, not only maintaining the operation comfort but also making the guiding gasket 800 tightly adhere to the contact part of the safety rope and the high-pressure rubber hose 100.
[0053] In an alternative embodiment, it further includes a member 110. An installation hole is arranged on the member 110, and a third lock 500 is arranged on the second lock 400. The third lock 500 is used to connect with the member 110.
[0054] In an alternative embodiment, the looped rope body is a steel wire rope.
[0055] In some embodiments, in order to better connect the safety rope to the component 110, a third buckle 500 is provided on the second buckle 400 for facilitating separation from the second buckle 400; generally, the component 110 is fixedly arranged, and an assembly hole is provided on the component 110. The third buckle 500 is assembled on the assembly hole of the component 110, thus realizing the connection between the third buckle 500 and the component 110.
[0056] The third buckle 500 is connected to the second buckle 400, thus fixing the safety rope on the component 110. When the high-pressure hose 100 is detached, the safety rope can make the high-pressure hose 100 swing within the moving range, avoiding the phenomenon that the high-pressure hose 100 swings disorderly over a large range and causing damage to nearby equipment, pipeline accessories, operators, etc.
[0057] The main body of the annular rope is preferably a steel wire rope, and other rope bodies can also be used for the main body of the annular rope; one end of the safety rope is detachably hinged to the component 110, and the component 110 is fixedly arranged and cannot move; the other end of the safety rope is hinged to the threaded connection joint of the high-pressure hose 100; to prevent the pipeline vibration caused by excessive pressure during the use of the high-pressure hose 100 and the loosening caused by insecure connection, and the phenomenon that the joint of the high-pressure hose 100 loosens and falls off and flies out to hurt people, etc. Using a flexible safety rope can effectively prevent the uncertain damage to nearby equipment, pipelines and operators caused by disorderly flying out after loosening, thus ensuring safety during use.
[0058] Finally, 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 foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
