A kind of safety rope of length adjustable.Mainly solve present safety rope and scarcely can regulate effective length, long safety rope, that in the time falling, will fall is farther, causes unnecessary injury, in the time that safety rope is too short, can cause again inconvenience, the problem that even cannot use of using.It is characterized in that: described catching device comprises upper lock body and down lock body, described ratchet one end and upper lock body are hinged, and the other end is connected with down lock body, also comprise torsion spring, and described torsion spring one end compresses and coordinates with upper lock body top, and the other end presses on described ratchet on rope body.The utility model provides a kind of safety rope of length adjustable, upper down lock body in its catching device connects by ratchet, between ratchet and upper lock body, be also provided with the torsion spring that compresses ratchet, ratchet at ordinary times can clamping rope body, in the time that needs regulate length, can press down lock body, ratchet just unclamps rope body, thereby safety rope just can move and regulate effective length, simple in structure, easy to use, safe and reliable.
Description
Technical field
The utility model belongs to safety rope field, particularly a kind of safety rope of length adjustable.
Background technology
In the positioning operation of high-altitude, commonly use safety rope, present safety rope scarcely can regulate effective length (being the distance of human body to self-locking device), long safety rope, that in the time falling, will fall is farther, causes unnecessary injury, in the time that safety rope is too short, can cause again inconvenience, the problem that even cannot use of using.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of safety rope of length adjustable, mainly solve present safety rope and scarcely can regulate effective length, long safety rope, that in the time falling, will fall is farther, causes unnecessary injury, in the time that safety rope is too short, can cause again inconvenience, the problem that even cannot use of using.
The technical scheme that the utility model adopts is:
A kind of safety rope of length adjustable, comprise rope body, described rope body one end is provided with safety door hook, the other end is provided with catching device, in described catching device, be provided with the ratchet with the body adaptation of restricting, described ratchet is provided with the ratchet for one-way lock tight rope body, on described catching device, be also connected with hook, described catching device comprises upper lock body and down lock body, described ratchet one end and upper lock body are hinged, and the other end is connected with down lock body, also comprise torsion spring, described torsion spring one end compresses and coordinates with upper lock body top, and the other end presses on described ratchet on rope body.
Described down lock body comprises through hole, and described rope body is provided with the first wearing bush and the second wearing bush, between described first and second wearing bush, is provided with adjusting rope, and the diameter of described first and second wearing bush is greater than the diameter of through hole, and described catching device is located on adjusting rope.
Described ratchet comprises the first ratchet and the second ratchet, the parallel installation of described first and second ratchet.
Described upper lock body is provided with and the hanging hole of linking up with adaptive formation and being fixedly connected with.
The beneficial effects of the utility model are: the utility model provides a kind of safety rope of length adjustable, upper down lock body in its catching device connects by ratchet, between ratchet and upper lock body, be also provided with the torsion spring that compresses ratchet, ratchet at ordinary times can clamping rope body, in the time that needs regulate length, can press down lock body, ratchet just unclamps rope body, thereby safety rope just can move and regulate effective length, simple in structure, easy to use, safe and reliable.
Brief description of the drawings
Fig. 1 is the front view of an embodiment of the utility model.
Fig. 2 is the schematic internal view of an embodiment of the utility model.
In figure, rope body 1, safety door hook 2, catching device 3, ratchet 31, ratchet 38, hook 4, upper lock body 32, down lock body 33, torsion spring 34, through hole 35, adjusting rope 13, the first wearing bush 11, the second wearing bush 12, the first ratchet 311, the second ratchets 312, hanging hole 321.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail: as shown in Figure 1 with Figure 2, a kind of safety rope of length adjustable, comprise rope body 1, described rope body 1 one end is provided with safety door hook 2, the other end is provided with catching device 3, in described catching device 3, be provided with the ratchet 31 with body 1 adaptation of restricting, described ratchet 31 is provided with the ratchet 38 for one-way lock tight rope body 1, on described catching device 3, be also connected with hook 4, described catching device 3 comprises upper lock body 32 and down lock body 33, described ratchet 31 one end and upper lock body 32 are hinged, the other end is connected with down lock body 33, also comprise torsion spring 34, described torsion spring 34 one end compress and coordinate with upper lock body 32 tops, the other end presses on described ratchet 31 on rope body 1.The utility model provides a kind of safety rope of length adjustable, upper down lock body in its catching device connects by ratchet, between ratchet and upper lock body, be also provided with the torsion spring that compresses ratchet, ratchet at ordinary times can clamping rope body, in the time that needs regulate length, can press down lock body, ratchet just unclamps rope body, thereby safety rope just can move and regulate effective length, simple in structure, easy to use, safe and reliable.When rope body passes through ratchet, only have one direction to move, it is locked that other direction belongs to, torsion spring is pushed ratchet to the direction of locked rope body, realize the effect of pressing the body of restricting to a certain degree, in the time that needs regulate length, can exert pressure and be greater than the active force of torsion spring down lock body, ratchet and rope body are separated, thereby can regulate the effective length of safety rope, in the time being adjusted to the length of adaptation, unclamp hand, ratchet will press again rope body, simple in structure, easy to use, ratchet only has unidirectionally can compress rope body, i.e. the direction of ratchet one-way lock dead line body.
In the utility model, as shown in the figure, described down lock body 33 comprises through hole 35, described rope body 1 is provided with the first wearing bush 11 and the second wearing bush 12, between described first and second wearing bush, be provided with adjusting rope 13, the diameter of described first and second wearing bush is greater than the diameter of through hole 35, and described catching device 3 is located on adjusting rope 13.Because the diameter of described first and second wearing bush is greater than the diameter of through hole 35, catching device regulates in the scope of adjusting rope again, and wearing bush can wear prevention, and simple in structure, result of use is good, safe and reliable.
In the utility model, as shown in the figure, described ratchet 31 comprises the first ratchet 311 and the second ratchet 312, the parallel installation of described first and second ratchet.Two ratchets are more safe and reliable, and rationally utilized the space of catching device the inside, and simple in structure, result of use is good.
In the utility model, as shown in the figure, described upper lock body 32 is provided with the hanging hole 321 being fixedly connected with the formation of linking up with 4 adaptations.Simple in structure, result of use is good, safe and reliable.
Embodiment should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection domain of the present utility model.
