The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 3, a safety mechanical lock comprises an attachment disc 1, a valve 2, a first rope 3 and a mechanical lock assembly 4, wherein the valve 2 is installed on the attachment disc 1, one end of the first rope 3 is movably clamped with the valve 2, the mechanical lock assembly 4 comprises a second rope 41, a fixing buckle 42 and a baffle 43, the fixing buckle 42 and the baffle 43 are fixed on the attachment disc 1, the second rope 41 comprises a rope sleeve 411 and a pull rope 412, the pull rope 412 penetrates through the baffle 43 and the rope sleeve 411 to be connected into a whole, the rope sleeve 411 is movably clamped between the fixing buckle 42 and the attachment disc 1, the rope sleeve 411 is connected with the middle of the first rope 3, and the other end of the first rope 3 is movably clamped with the baffle 43. Specifically, in this embodiment, the valve 2 is installed on the attachment plate 1, the connection between the attachment plate 1 and the outside is controlled by the valve 2, when the valve 2 is opened, the air pressure between the attachment plate 1 and the wall surface is increased, and the attachment plate 1 can be removed from the wall surface and reattached. The air valve 2 is in a normally closed state under the action of atmospheric pressure, and can be opened when a user manually overturns the air valve 2. In order to prevent the valve 2 from being opened by misoperation of a user, a mechanical lock assembly 4 is arranged to cooperate with the first rope 3 to control the valve 2. When the second rope 41 is acted by an external force downward along the direction of the pull rope 412, the rope sleeve 411 simultaneously acts the force on the first rope 3, the first rope 3 is simultaneously acted by an upward pulling force, so that one end of the first rope 3 is abutted to the baffle 43, and the first rope 3 is in a tightened state. When a user presses the valve 2, the first rope 3 between the valve 2 and the stop block 43 is tightened, so that the valve 2 cannot be overturned, the purpose of locking the valve 2 is achieved, and the user is prevented from touching the valve 2 by mistake. In the actual use process, the downward pulling force of the pulling rope 312 is usually provided by the foot of the user, the foot of the user steps on the pulling rope 412, the hand of the user grips on the attachment plate 1, and when the foot of the user steps on the corresponding pulling rope 412 all the time, the air valve 2 is locked, the attachment plate 1 cannot be inflated, and the attachment plate 1 cannot be loosened. When the user's foot leaves the pull rope 412, the second rope 41 and the first rope 3 are loosened at the same time, and the user can turn over the valve 2 by the first rope 3, so that the attachment plate 1 is loosened from the wall surface. In addition, because the people is when the climbing, the gravity that the user weight produced is whole to be transmitted to the fag end 411 by stay cord 412 on, fag end 411 atress and fixed knot 42 butt, only transmit partial pulling force to first rope 3 on, first rope 3 receives an ascending pulling force to tighten the back, its tip and baffle 3 butt, uses fixed knot 42 to undertake the most pulling force that the user climbed the time produced, avoids baffle 3 not hard up. The mechanical lock assembly 4 is integrated on the attachment plate 1, so that the personal safety of a user climbing on a high-altitude wall surface is ensured, the operation is simple, and the application prospect is better.

As shown in fig. 2-3, the first rope 3 is sleeved with a return spring 31, the return spring 31 is sleeved between the fixing buckle 42 and the baffle 43, one end of the return spring 31 is abutted against the fixing buckle 42, and the other end of the return spring 31 is fixedly connected with the first rope 3. Specifically, in this embodiment, the return spring 31 is sleeved on the first rope 3, and when the user presses the valve 2 by hand to open the valve, the first rope 3 is connected between the valve 2 and the stopper 43 in a tightened state, and the return spring 31 is compressed by the fixing buckle 42. When the external force applied by the user on the valve 2 disappears, the return spring 31 returns to the natural state to drive the first rope 3 to move downwards, so that the end of the first rope 3 close to the stop block 43 is automatically away, and the valve 2 is automatically closed by the tension of the first rope 3.

As shown in fig. 2 to 3, a protrusion 32 is disposed at one end of the first rope 3 adjacent to the baffle 43, and the first rope 3 penetrates through the baffle 43 and is connected to the protrusion 32. Specifically, in the present embodiment, in order to make the stopper 43 play a role of stopping, the protrusion 32 is disposed at the end of the first rope 3, the first rope 3 penetrates through the stopper 43 and is connected to the protrusion 32, and when the first rope 3 displaces in the stopper 43, the protrusion 32 stops and stops to prevent the first rope 3 from being pulled out of the stopper 43. In other embodiments, the end of the first rope 3 may be knotted to perform a stopping function.

As shown in fig. 2, the device further comprises a hose 5, wherein the hose 5 is fixedly mounted on the attachment plate 1, and the first rope 3 is movably mounted in the hose 5. Specifically, in order to avoid the scattered distribution of the first ropes 3 on the attachment plate 1, the hose 5 is arranged for restraining the first ropes 3, the hose 5 is fixed on the attachment plate 1 through a buckle and other components, and the diameter of the first ropes 3 is smaller than that of the hose 5, so that the first ropes 3 can freely displace in the hose 5 under the action of external force.

As shown in fig. 2 to 3, the mechanical lock assembly 4 further includes a housing 44, and the housing 44 covers the fixing buckle 42 and the baffle 43 and is connected to the attachment plate 1. Specifically, in this embodiment, set up shell 44 and play the guard action, avoid the direct first rope 3 and the contact of second rope 41 with the activity of user's hand, prevent that user's hand is injured, and avoid the entering of outside particulate matter, influence the operation of first rope 3 and second rope 41.

As shown in fig. 2, the first rope 3 and the second rope 41 are steel ropes. Specifically, the steel rope has strong tensile force, is not easy to break and has high reliability.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
