Problems solved by technology

Now some methods are to temporarily tie one end of a rope to the tool, and the other end to the wrist or the belt on the body of the installation and maintenance personnel. This method is very temporary and random, and it is difficult to bind and easy to loosen. Maintenance personnel are unwilling to operate in this way, often causing accidents

Embodiment Construction

[0012] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0013] Such as figure 1 and figure 2 As shown, a tool anti-dropping device includes: an adhesive button upper cover 1, an adhesive button lower cover 2, a wrist guard 3, a safety rope 4, a spring buckle 5, a hook seat 6, and a hook 7. The two ends of the safety rope 4 are respectively connected to the hook seat 6 and the wrist guard 3, the adhesive buckle upper cover 1 and the adhesive buckle lower cover 2 are sewn on the said wrist guard 3, and the hook seat 6 is fixedly connected with Hook 7 and spring buckle 5.

[0014] The safety rope 4 is made of high tensile strength material (such as nylon).

[0015] Described wristband 3 is made of soft and high-intensity material (such as canvas).

[0016] The working process of the present invention is: when using the installation and maintenance tools of air conditioners and other equipment, first open ...

Abstract

The invention relates to a tool anti-falling device comprising an adhesive fastener upper cover, an adhesive fastener lower cover, a wrist guard, a safety rope, a spring fastener, a hook base and a hook. Both ends of the safety rope are respectively connected with the hook base and the wrist guard which is sewed with the adhesive fastener upper cover and the adhesive fastener lower cover; the hook base is fixedly connected with the hook and the spring fastener; the safety rope is made from a material (such as nylon) with high tensile strength; and the wrist guard is made from a flexible and high-strength material (such as canvas). When the tool anti-falling device provided by the invention is in use, a mounting and repairing tool can be effectively prevented from falling from overhead so as to avoid the danger of smashing objects or knocking people. The device is rapid and convenient to operate without influencing the normal use of the mounting and repairing tool and has a simple structure and convenience in manufacture.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a tool anti-dropping device. Background technique [0002] In the installation and maintenance of air conditioners and other equipment at high altitude, it is often necessary to use tools such as adjustable wrenches and pipe wrench. During installation and maintenance operations, sometimes it takes a lot of force to loosen or tighten pipe fittings, nuts, etc. If too much force is used, the tool is easy to leave the hand, especially when there is oil on the handle of the tool. At this time, the tool will fall to the ground, which not only delays working hours, but also has the danger of smashing objects or even injuring people. Now some methods are to temporarily tie one end of a rope to the tool, and the other end to the wrist or the belt on the body of the installation and maintenance personnel. This method is very temporary and random, and it is difficult to bind and easy to loosen. Maintena...
