Detailed Description

Certain terms are used throughout the description and claims to refer to particular components. Those of skill in the art will appreciate that a hardware manufacturer may refer to the same component by different names. The description and claims do not take the form of an element differentiated by name, but rather by functionality. As used throughout the specification and claims, the word "comprise" is an open-ended term, and thus should be interpreted to mean "include, but not limited to. The description hereinafter sets forth a preferred embodiment for practicing the utility model, but is not intended to limit the scope of the utility model, as the description is given for the purpose of illustrating the general principles of the utility model. The scope of the utility model is defined by the appended claims.

The present utility model will be described in further detail below with reference to the drawings, but is not limited thereto.

Examples

As shown in fig. 2 to 5, a chest type lifter comprises a lifter body 1, wherein a ratchet part 1a is arranged on the lifter body 1 through a first hinge shaft 1a1, a rope channel on the lifter body 1 is opened or closed through the ratchet part 1a which can be rotated, a lower connecting hole 1c is arranged at the lower end of the lifter body 1, an upper connecting part slot 1d is arranged at the upper end of the lifter body 1, a detachable bolt 1e is arranged at the position of the upper connecting part slot 1d, a knob part 1e1 is arranged at one end of the bolt 1e, a limit groove 1e2 is arranged at the other end of the bolt 1e, and the bolt 1e is arranged at the position of the upper connecting part slot 1d and then extends into the limit groove 1e2 through a pin 1f for limiting and fixing. As shown in fig. 6, in use, the lower connecting hole 1c of the lifter body 1 is connected with the lower connecting hook 2b in front of the seat belt 2, and the connecting belt 2a in front of the seat belt 2 is connected with the detachable plug pin 1e arranged at the position of the slot 1d of the connecting part, so that the plug pin 1e can be pulled out when the seat belt is worn, then the upper connecting belt 2a in front of the seat belt 2 is placed at the slot 1d of the connecting part, then the plug pin 1e is penetrated, and the pin 1f is further implanted into the limit slot 1e2 of the plug pin 1 e. Thereby making the wearing of the safety belt 2 more convenient and the suitability good.

Preferably, the limit groove 1e2 provided by the plug pin 1e is an annular groove. Therefore, the pin 1f is positioned at an eccentric position of the axis of the bolt 1e, and after the pin 1f stretches into the limit groove 1e2, the bolt 1e can also rotate, so that friction between the bolt 1e and the connecting belt 2a of the safety belt 2 in the using process can be reduced.

Preferably, a compressing torsion spring 1g is further arranged between the ratchet part 1a and the lifter main body 1, and the tooth part of the ratchet part 1a is always in a compressing state on the rope in the rope channel under the action of the compressing torsion spring 1 g.

More preferably, the ratchet part 1a is further provided with a trigger 1h, the trigger 1h is rotatably provided on the ratchet part 1a through a second hinge shaft 1h1, and a return spring 1i is further provided between the trigger 1h and the ratchet part 1 a.
