Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, in particular to an anti-drop wrench for aerial work. Background Art

[0002] The adjustable wrench is a must-have tool for workers to carry out maintenance work at heights. It is used to tighten and strengthen the bolts of the tower. The UHV tower head bolts are mainly distributed in models M16, M20 and M24. When workers carry out bolt tightening work, they need to tighten each bolt. When using a wrench, they use a fixed wrench and an adjustable wrench in rotation to achieve the corresponding tightening rate. The intensity of workers working at high altitudes is high, and the use of multiple tools is difficult and heavy. The physical strength of the workers is consumed too quickly, and objects are prone to falling from high altitudes, which poses a great safety hazard. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figures 1 to 4 , an anti-drop wrench for high-altitude operation, comprising:

[0023] The wrench body 10 has two ends in a Z shape, and the wrench body 10 is provided with a first slide groove 101 and a second slide groove 102 penetrating therethrough, and the first slide groove 101 and the second slide groove 102 are communicated with each other;

[0024] Two circular wrench heads 2, each disposed at one end of the wrench body 10, the two wrench heads 2 are both provided with a first jaw 201 adapted to the hexagonal nut, and the two first jaws 201 are of different sizes;

[0025] A plurality of sleeves 3, which can cooperate with the first jaw 201 on one of the wrench heads 2, and a plurality of the sleeves 3 are provided with a second jaw 301 adapted to the hexagonal nut;

[0026] A plurality of stoppers 4, each of which is disposed at the upper and lower ends of the sleeve 3 and is detachably connected to the upper and lower ends of the sleeve 3;

[0027] The sliding part 5 includes a sliding rod 501 and two T-shaped locking rods 502. The sliding rod 501 can slide in the second sliding groove 102. The locking rods 502 are threadedly connected to the sliding rod 501.

[0028] The elastic rope 6 has one end connected to the slide bar 501. In the utility model, a wrench head 2 is provided at each end of the wrench body 10, and the first jaws 201 on the two wrench heads 2 are of different sizes. The wrench can be used in conjunction with two hexagonal nuts of different sizes. The sleeve 3 can be matched with the first jaw 201 and the sleeve 3 is provided with a second jaw 301. The second jaw 301 can be matched with the hexagonal nut. That is, when the wrench is in use, it can be used in conjunction with two hexagonal nuts of different specifications. When it is necessary to tighten or disassemble a hexagonal nut of a smaller specification, the sleeve 3 can be selected according to the hexagonal nut of the required specification, thereby improving the practicality of the wrench. In addition, the two ends of the wrench body 10 are in a Z shape, which makes it easier for workers to tighten or disassemble the hexagonal nuts. When the worker is operating, the hand is at a certain height from the object fixed by the bolt and the hexagonal nut to prevent the hand from touching the object and causing damage. The function of the stopper 4 prevents the sleeve 3 from falling off the first jaw 201. Due to the high-altitude operation, when the wrench is used, one end of the elastic rope 6 is tied to the worker's wrist, and the elastic rope 6 is pulled to move the sliding part 5 to the position close to the wrench head 2 to prevent the wrench from falling when the worker operates improperly. The sliding rod 501 is provided with a threaded hole through it, and one end of the two locking rods 502 are connected to the threaded holes on the sliding rod 501, and then the sliding rod 501 is fixed in the second slide groove 102, so that it can slide in the second slide groove 102. Specifically, one end of the locking rod 502 is provided with an external thread; the sleeve 3 is provided with a bolt model, which is convenient for quickly finding the corresponding sleeve 3.

[0029] As a preferred embodiment of the utility model, it may also have the following additional technical features:

[0030] In this embodiment, a screw 5021 is provided on one of the locking rods 502, and the screw 5021 is threadedly connected to one end of the other locking rod 502. One end of the locking rod 502 is provided with a threaded hole matched with the screw 5021, so that the connection between the sliding rod 501 and the two locking rods 502 is more firmly.

[0031] In this embodiment, a plurality of arc-shaped protrusions 5022 are provided on the locking rod 502 , and the arc-shaped protrusions 5022 are in contact with the side wall of the wrench body 10 , thereby reducing friction and facilitating movement.

[0032] In this embodiment, the stopper 4 is a rubber ring. During installation, the rubber ring is first put on one end of the sleeve 3. After the sleeve 3 can cooperate with the first jaw 201, the rubber ring is then put on the other end of the sleeve 3.

[0033] In this embodiment, one end of the elastic rope 6 is provided with an adjustable tightness movable rope buckle, and one end of the elastic rope 6 is knotted into a movable rope buckle. The operator only needs to put his hand into the rope buckle and pull the rope to adjust the tightness.

[0034] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
