the shoulder strap 11 is in an inverted V shape, the back hanging ring 16 is fixedly connected to the corner point of the shoulder strap 2, and two strap body units at one end of the shoulder strap 11, which is far away from the back hanging ring 16, respectively extend downwards and are sequentially sewn and fixed with the waist belt 13 and the leg straps 14; the shoulder strap 1 is a closed loop, one end of the stretched two ends of the shoulder strap passes through the back hanging ring 16, and the other end of the stretched two ends of the shoulder strap is sewn with the chest strap 12 to form a double shoulder strap; the waist ring 15 is fixedly connected to the waist belt 13 and is positioned right below the front chest belt 12; the lock catch 17 is connected between the free end of the front chest belt 12 and the waist ring 15; the connecting belt 18 is fixedly connected between the leg belt 14 and the waist belt 13 and close to one side of the waist ring 15, and is used for reinforcing the leg belt 14;
in the preferred embodiment, the shoulder straps 1, the back straps 11, the waist straps 13 and/or the leg straps 14 are provided with adjusting buckles 19. Through adopting above-mentioned technical scheme, adjust the setting of knot 19 for operating personnel can adjust by oneself according to the needs of dressing, makes the safety belt fit more, so that high altitude construction.
In addition, still the rigid coupling has protecting band 2 on waistband 13, protecting band 2 keeps away from waistband 13's one end rigid coupling has safety hook 3 for carry out the hook with the railing that operating personnel climbed, thereby protect operating personnel. In this embodiment, the two sets of the protective belts 2 and the safety hooks 3 are respectively disposed on two sides of the waist belt 13. During high altitude construction, operating personnel accessible two sets of protecting band 2 and safety hook 3 carry out the hook to improve the security that operating personnel climbed.
As shown in fig. 1 and 2, the safety hook 3 includes a hook 31 and a hook component 32 which are C-shaped, the hook 31 is a main body of the safety hook 3, one end of the hook 31 is rotationally connected with two hinge shafts through bearings along a radial direction, the two hinge shafts are located on the same axis, each hinge shaft is sleeved with a torsion spring 311, and the hinge shaft is used for installing the hook component 32.
As shown in fig. 2 and 3, the hook assembly 32 includes a hinge plate 321, a movable post 322 and a fixed post 323, two sides of the hinge plate 321 are fixedly connected with two hinge shafts respectively, a torsion spring 311 is sleeved on each hinge shaft, one end of the torsion spring 311 is fixedly connected with the hinge plate 321, the other end of the torsion spring is fixedly connected with the hook 31, the movable post 322 is fixedly connected with one end of the hinge plate 321 far away from the hinge shaft, the fixed post 323 is fixedly connected with one end of the hook 31 far away from the hinge shaft, and the movable post 322 is connected with the fixed post 323. In this embodiment, the hinge plate 321 is an arc plate, the diameter of the hinge plate 321 is greater than that of the hook 31, the hinge plate 321 surrounds half of one end of the hook 31 where the hinge shaft is disposed, and a part of the end is exposed, one end of the hinge shaft, which is far away from the hook 31, is welded to the inner peripheral wall of the hinge plate 321, one end of the torsion spring 311 is welded to the hinge plate 321, the other end of the torsion spring is welded to the hook 31, and the torsion spring 311 is in an unstressed state at this time, a yielding opening is formed in the plate surface of the hinge plate 321, and when the hinge plate 321 rotates along the hinge shaft, the hook 31 can just penetrate through the.
Furthermore, a clamping strip 3221 is fixedly connected to the movable post 322, a clamping groove 3231 is formed in the fixed post 323, and the clamping strip 3221 is clamped with the clamping groove 3231. Through adopting above-mentioned technical scheme, card strip 3221 and draw-in groove 3231's joint cooperation can carry out axial and radial dual spacing to activity post 322 and fixed column 323, then further reduces the possibility that safety hook 3 unhook. Specifically, the movable post 322 is coaxially welded at one end of the hinge plate 321 away from the hook 31, a semi-cylindrical first gap is axially cut at one end of the movable post 322 away from the hinge plate 321, and a rectangular clamping strip 3221 is axially and integrally formed on the cross section of the first gap. Correspondingly, the fixing column 323 is coaxially welded at one end of the hook 31 far away from the hinge shaft, a semi-cylindrical second gap is axially cut at one end of the fixing column 323 far away from the hook 31, a rectangular clamping groove 3231 is axially formed in the cross section of the second gap, and the clamping groove 3231 can be embedded and matched with the clamping strip 3221.
The specific implementation principle is as follows:
when the safety hook 3 is in a closed state, the arc-shaped opening of the hinged plate 321 is opposite to the C-shaped opening of the hook 31, the first opening of the movable post 322 is opposite to the C-shaped opening of the hook 31, the second opening of the fixed post 323 is opposite to the C-shaped opening of the hook 31, the opening of the movable post 322 is overlapped with the opening of the fixed post 323, and the clamping strip 3221 is just embedded in the clamping groove 3231, when the safety hook 3 is used, a worker can take the safety hook 3 to align the movable post 322 with the climbing handrail and apply force to push the movable post 322, at the moment, the movable post 322 can rotate towards the C-shaped opening of the hook 31 along the hinged shaft, the clamping strip 3221 can be pulled out of the clamping groove 3231 so that the safety hook 3 is opened and closed, the handrail can smoothly enter the safety hook 3, at the moment, due to the arrangement of the torsion spring 311, after the safety hook 3 hooks the handrail, the movable post 322 can rebound to an original state, namely, the, card strip 3221 also can imbed draw-in groove 3231 again, safety hook 3 is in the closure state again, has accomplished safety hook 3 this moment promptly and has got fixedly in the hook on the railing, when needs remove safety hook 3, utilizes the hand push movable column 322 to rotate to make safety hook 3 be in the state that opens and shuts, then take off safety hook 3 from the railing can, when the continuous climbing that makes progress of staff in the same reason, usable above-mentioned safety hook 3's use mode, it can to get or remove to hook once more.
Here, when the worker completes the work high above the ground and climbs downward, the worker uses the safety hook 3 in the same manner as described above.
Adopt this embodiment, setting through this safety belt, the staff is when the climbing, the first opening of activity post 322 can form radially spacingly with the second opening of fixed column 323 coincidence in pothook subassembly 32, card 3221 can form axial and radial dual spacing again with draw-in groove 3231's cooperation, pothook subassembly 32's structure has carried out more comprehensive spacing to safety hook 3 promptly, and simultaneously, safety hook 3 gets the railing after the hook, the railing is in the safety hook 3 no matter how movable, because the structure of activity post 322 and fixed column 323, all be difficult for making safety hook 3 open and shut, then make the phenomenon that safety hook 3 is difficult for taking place to unhook in the use, staff's safety when further having guaranteed high altitude construction.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
