[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In the description of the present utility model, "first feature" and "second feature" may include one or more of the features. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0025] like Figure 1-Figure 5 The transformer maintenance safety belt safety hook hanging rod shown is characterized by comprising: a base 1, a connecting seat 4, a binding belt 7 and a tightening seat 8.

[0026] like Figure 1 and Figure 2 As shown, a vertical pole 2 is provided on the base 1, and a hanging ring 3 is provided on the pole 2. The hanging ring 3 can be used to connect a safety belt. The number of hanging rings 3 can be multiple, so that multiple safety belt hanging rings 33 better meet the needs of construction and can support multiple people working or one person working in multiple places. The specific number and height position of the hanging ring 3 are not limited here, and the design can be adjusted according to actual needs. In actual applications, multiple devices of this device can also be used according to needs. At this time, a steel wire rope can be used to connect the hanging rings 3 of several devices, so that the safety belt can be directly hung on the steel wire rope, so that it can slide at will, which is convenient for maintenance personnel to move in more positions.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the base 1 is detachably connected to the connecting seat 4 by a bolt connector, a first chain plate 5 is provided on one side of the connecting seat 4, and a second chain plate 6 is provided on the other side; a strap 7 is provided at the end of the first chain plate 5 away from the connecting seat 4; the tightening seat 8 includes a seat body 9, a twisting shaft 10 and a ratchet 15 limiting mechanism, the seat body 9 is provided at the end of the second chain plate 6 away from the connecting seat 4, the twisting shaft 10 is rotatably provided on the seat body 9, the twisting shaft 10 is provided with a belt threading hole 11, and the ratchet 15 limiting mechanism is used to limit the twisting shaft 10.

[0028] In practical applications, the device is generally installed on a cylindrical component, such as a cylindrical pipe rack. When in use, the strap 7 is passed through the strap hole 11 of the twist shaft 10, and then the strap 7 is tightened, and then the twist shaft 10 is rotated, and the strap 7 is continuously wound around the twist shaft 10 to achieve tightening of the strap 7. In this case, the continuously tightened strap 7 and the first chain plate 5 and the second chain plate 6 will tightly hold the cylindrical component in the middle, so that the device is firmly fixed.

[0029] Moreover, in the present device, the ratchet 15 limiting mechanism is used to lock and limit the twist shaft 10, which can effectively prevent the twist shaft 10 from loosening. This limiting form is simple and easy to implement.

[0030] In further settings, such as Figure 1-Figure 2 As shown, the upright pole 2 is detachably connected to the base 1, so that the upright pole 2 can be disassembled as needed, which is convenient for transportation and storage of the device. The base 1 is provided with a pipe sleeve 12, and the side wall of the pipe sleeve 12 is provided with a vertical groove, and the two sides of the groove are provided with ear plates 13 fixedly connected to the pipe sleeve 12, one ear plate 13 is provided with a screw hole, and the other ear plate 13 is provided with a through hole, and a screw 14 with a handle passes through the through hole and is connected to the screw hole, the upright pole 2 is inserted into the pipe sleeve 12, and the screw 14 is tightened. The pipe sleeve 12 is tightened to fix the upright pole 2, and the screw 14 is loosened to remove the upright pole 2, which is very convenient.

[0031] like Figure 3-Figure 5 As shown, the ratchet 15 limiting mechanism includes a ratchet 15, a pawl 16, a torsion spring 17, a pin 18 and a handle 20. The ratchet 15 is fixed on the twist shaft 10, the pin 18 is rotatably arranged on the seat body 9, the pawl 16 is fixed on the pin 18, the torsion spring 17 is sleeved on the pin 18, one end of the torsion spring 17 is connected to the seat body 9, and the other end is connected to the pawl 16. The pawl 16 engages with the ratchet 15 under the action of the torsion spring 17, and a handle 20 is fixed on one end of the pin 18.

[0032] Therefore, under the action of the torsion spring 17, the pawl 16 will always tend to engage with the ratchet 15, and the one-way locking of the winding shaft 10 can be achieved through the engagement of the pawl 16 and the ratchet 15. That is, in this case, the winding shaft 10 can rotate in the forward direction to tighten the strap 7, but cannot rotate in the reverse direction. When the strap 7 needs to be loosened, the handle 20 needs to be manually rotated to drive the pin 18 to overcome the elastic force of the torsion spring 17 and rotate. At this time, the pawl 16 is disengaged from the ratchet 15, and the winding shaft 10 can be rotated in the reverse direction to loosen the strap 7.

[0033] A screwing head 21 is fixedly provided at one end of the twisting shaft 10. The screwing head 21 is a hexagonal head, so that a tool such as a wrench can be used to clamp on the screwing head 21 to tighten the twisting shaft 10, which is labor-saving and convenient to operate.

[0034] To sum up, compared with existing products, the present device can disassemble the upright pole 2 as needed, which is convenient for transportation and storage of the present device. The twisted shaft 10 used to tighten the strap 7 is locked and limited by a ratchet 15 limiting mechanism, which can effectively prevent the twisted shaft 10 from loosening. This limiting form is simple and easy to implement. The overall structure of the present device is simple, easy to use, and highly practical.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
