Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a belt type wrench device. Background Art

[0002] During construction, a large number of small components such as pipes need to be rotated and tightened. In order to meet the standardization and regularization of construction, it is usually necessary to rotate and tighten small components such as pipes of different diameters without causing damage, especially pipes with larger diameters. However, at the construction site, a simple wrench device suitable for the rotation and tightening of small components such as pipes and flexible and easy to operate is rare, and the existing tightening devices are not simple and flexible enough and cannot be used for the rotation and tightening of small components such as pipes, resulting in increased costs and inconvenience in construction. Therefore, we need to propose a belt wrench device. Utility Model Content

[0003] The purpose of the utility model is to provide a belt wrench device, which overcomes the problems that traditional fastening devices are not simple and flexible enough and cannot be used for the rotational fastening of small components such as pipes, thereby causing increased costs and inconvenience in construction, so that the rotational fastening method for small components such as pipes is improved to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A belt wrench device comprises a belt, one side of which is fixedly provided with teeth for clamping small pipe components, one end of the belt is provided with a connector, and one end of the connector is connected with an elbow handle used in conjunction with the belt.

[0006] Preferably, the connecting member includes two groups of rotating shafts, one group of rotating shafts is rotatably installed on one end of the belt, and the other group of rotating shafts is rotatably installed on the end of the elbow handle close to the elbow, and a group of connecting plates are installed on the outer walls of the adjacent ends of the two groups of rotating shafts.

[0007] Preferably, both end portions of the rotating shaft are fixedly connected with limiting plates, and one side of the limiting plates is in contact with the side wall of the connecting plate.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The utility model arranges a belt to tightly cover the object to be rotated, so that the teeth on the belt contact the outer wall of the tubular part to be rotated, and then the elbow handle is held and the belt at the elbow handle is held and rotated. During the rotation, the elbow of the elbow handle will be tightly pressed on the belt. As the elbow handle rotates, the belt is increasingly tightly covered on the outer side of the tubular part to be rotated until the tubular part to be rotated rotates along with the belt under the action of friction, thereby realizing rotation and tightening of small components such as pipes. When the rotation and tightening are completed, the elbow handle is rotated in the opposite direction. At this time, the pressure on the belt at the elbow of the elbow handle disappears, and the belt can be removed from the small components such as pipes that have been rotated and tightened. This not only makes it convenient for construction personnel to manufacture the device on demand, but also ensures the rotation effect, and is convenient for construction personnel to rotate small components such as pipes. The utility model has the advantages of flexible and easy use, simple structure, reduced cost, and improved efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] 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.

[0015] See also Figure 1-3 The utility model provides a belt wrench device, including a belt 1, one side of the belt 1 is fixedly installed with teeth 2 for clamping small pipe components, one end of the belt 1 is installed with a connecting piece 3, and one end of the connecting piece 3 is connected to an elbow handle 4 used in conjunction with the belt 1.

[0016] The connecting member 3 includes two groups of rotating shafts 31, one group of rotating shafts 31 is rotatably installed on one end of the belt 1, and the other group of rotating shafts 31 is rotatably installed on the end of the elbow handle 4 close to the elbow. A group of connecting plates 32 are installed on the outer walls of the adjacent ends of the two groups of rotating shafts 31, so as to facilitate the connection of the two groups of rotating shafts 31 through the cooperation of the two groups of connecting plates 32.

[0017] Both ends of the rotating shaft 31 are fixedly connected with limiting pieces 33, and one side of the limiting piece 33 is in contact with the side wall of the connecting plate 32, so that the rotating shaft 31 can be limited by the limiting piece 33 to prevent the rotating shaft 31 from falling off.

[0018] It is worth noting that the site can make full and reasonable use of materials according to actual construction needs and make the device on demand at any time, saving costs and facilitating construction.

[0019] Working principle: When the utility model is constructed, according to the needs of the construction, firstly, one end of the belt 1 is passed through the gap between the connecting pieces 3 to make the belt 1 wind into a cavity, and the belt 1 is put on the outside of the tubular piece 5 to be rotated, so that the teeth 2 on the belt 1 are against the outer wall of the tubular piece 5 to be rotated, and then the elbow handle 4 is held and the belt 1 at the elbow handle 4 is held and rotated. During the rotation process, the elbow of the elbow handle 4 will be tightly pressed on the belt 1. As the elbow handle 4 rotates, the belt 1 is more and more tightly put on the outside of the tubular piece 5 to be rotated until the tubular piece 5 to be rotated is rotated. The tubular member 5 also rotates with the belt 1 under the action of friction, thereby realizing rotational tightening of small components such as pipes. When the rotation and tightening is completed, the elbow handle 4 is rotated in the opposite direction. At this time, the pressure on the belt 1 at the elbow of the elbow handle 4 disappears, and the belt 1 can be removed from the tubular member 5 to be rotated that has been rotationally tightened. Therefore, the device makes the rotational tightening method of small components such as pipes particularly convenient and safe, and solves the problem that traditional tightening devices are not simple and flexible enough and cannot be used for the tightening of small components such as pipes, thereby causing problems such as increased costs and inconvenience in construction.
