Description

The sebific duct chest expander

The utility model relates to a kind of human body exercising device, is a kind of improvement of human upper limb exercising device structure specifically.

The chest expander of people's use at present, generally form by handle and steel spring, produce elastic force after spring is stretched, it is long more to stretch, and spring deformation is big more, elastic force is also big more, around this principle, make chest expander, people are as health, upper limbs particularly, the exercising device in chest and muscle of back and joint.This instrumentation spring is as the parts of chest expander, and weight is heavier, and pliability is poor, and inconvenience is carried, and is careless slightly in the process that stretching is again and again shunk in the training of health because the hardness of steel spring own is big, gets on the human body, produces pain.Before the utility model design is finished, not seeing the chest expander identical with the utility model structure as yet uses in daily life, not seeing the chest expander identical with the utility model structure has sale on market, it is on the books in the literature also not see the chest expander identical with the utility model structure.

The purpose of this utility model is to provide a kind of sebific duct chest expander, and weight is low weight, is easy to carry, and can injure human body in the training process that stretching is again and again shunk.

For achieving the above object, the utility model adopts following technical proposals:

The sebific duct chest expander, by two handles, two handle bands, sebific duct, sebific duct padlock device constitutes, handle is cylindrical, the handle band passes a handle, has a sebific duct hole on the handle band at least, one end of sebific duct passes the sebific duct hole, in sebific duct, fill in a plastics glue pipe close, the sebific duct plug is the circular cone bench-type, big bottom surface is hollow, diameter is identical with the sebific duct bore dia, handle face diameter is less than the sebific duct bore dia, the other end of sebific duct passes the circular hole of sebific duct padlock device, another root handle band passes handle crack with seam and another handle of sebific duct padlock device, sebific duct padlock device is made of matrix and tension piece, matrix is the unit of plastic that has rectangular build cavity, cavity is positioned at the top of unit of plastic, account for 1/2nd of matrix volume, the top of matrix has a circular hole that communicates with cavity at least, an inclined hole identical with the circular hole quantity on matrix top arranged at the bottom of matrix, this inclined hole is concentric with the circular hole that the top of matrix communicates with cavity at the ellipse that the face that contacts with cavity forms, the tension piece is the identical unit of plastic of rectangular build cavity size with matrix, one side of tension piece has handle crack with seam, run through the circular hole of straining piece and the inclined hole that with circular hole intersect identical with matrix top circular hole quantity arranged on the tension piece, all the external diameter with sebific duct is close for the circular hole that tension piece and matrix are all or the aperture of inclined hole, the other end of sebific duct passes the circular hole of sebific duct padlock device, tension on the piece circular hole and the inclined hole of matrix bottom, in sebific duct, fill in a plastics glue pipe close, work as binding lever, fill in circular cone bench-type sebific duct plug in the sebific duct of insertion handle band, because the diameter of the big bottom surface of sebific duct plug is identical with the sebific duct bore dia, so an end of sebific duct is by being fixed on the handle band tightly, work as binding lever, insert the circular hole on the top of sebific duct padlock device matrix, the sebific duct of the circular hole on the tension piece and the inclined hole of matrix bottom, because the displacement of tension piece, make sebific duct being fixed on the sebific duct padlock device tightly, owing to have a sebific duct hole at least on the handle band, has a sebific duct hole on the sebific duct padlock device at least, can be provided with one, two, three, four, five sebific ducts.

The utility model has following effect and good effect:

Because the steel spring that adopts in the chest expander that the utility model adopts sebific duct to replace people to use, structurally done very big improvement, thereby, the weight of chest expander alleviates greatly, sebific duct has bigger flexibility and pliability than steel spring, thereby be easy to carry, and in the training process that stretching is again and again shunk, can not injure human body.
