Abstract

The utility model discloses a wall pulley. The wall pulley comprises a handheld handle (1), a plurality of springs (2) and a rope (3) arranged in the springs (2), wherein soft protecting sleeves (4) are arranged outside the springs (2) in a sleeved mode, the protecting sleeves (4) are elastic components which are stretchable in the length direction, and the maximum stretching length of the protecting sleeves (4) is consistent with the maximum stretching length of the springs (2) in the length direction. According to the wall pulley, due to the fact that the protecting sleeves are arranged outside the springs, when the wall pulley stretches or shrinks, the skin or the hair cannot be clamped by the springs due to blocking of the protecting sleeves, and safety of an exerciser is greatly improved.

Description

A kind of chest expander

Technical field

The utility model relates to sporting goods technical field, more particularly, relates to a kind of chest expander.

Background technology

Chest expander is one of conventional exercise apparatus of people, because it is simple and easy to use, small volume, can use at home, therefore be subject to extensively liking of people, particularly young man, daylong working is very tired, does not have again the sufficient time to go to body-building shop to take exercise at evening or weekend, using the utensils such as chest expander to carry out the best selection of adaptive physical exercise at home, is also one of the most effective exercising way.

Existing chest expander is by spring and pulls and supports handle and form, and in the process pulling, spring, pulling open in the process of shrinking again, is easy to sporter's skin or hair etc. to clamp, and easily causes unnecessary injury.

Utility model content

The technical problems to be solved in the utility model is easily clamped the problem of skin or hair for existing chest expander, a kind of chest expander is provided.

The technical solution of the utility model is as described below: a kind of chest expander, comprise: gripping handle, some springs and the built-in rope of spring, described in each root, the two ends of spring are removably connected with described gripping handle respectively, described in each root, the inside of spring is provided with a built-in rope of described spring, the two ends of the built-in rope of described spring are individually fixed in corresponding described spring end, the length of the built-in rope of described spring and described spring maximum tension state equal in length.

The outer cover of described spring is provided with the protective jacket of one deck flexibility, described protective jacket is at the telescopic elastic component of length direction, the two ends of described protective jacket are connected with described gripping handle by drag-line respectively, and described protective jacket is consistent in the maximum tension length of length direction and the maximum tension length of described spring.

Described protective jacket entangles some described springs simultaneously, or protective jacket described in sheathed one deck in outside of spring described in each root, and described protective jacket is transparent elastic cover.

The utility model is by the outer setting protective jacket at spring, and like this, when this chest expander shrinks in stretching again, due to the obstruct of this protective jacket, spring can not clamped skin or hair, and person taking exercise's security is improved greatly.

Gripping handle in the drawings, 1; 2, spring; 3, the built-in rope of spring; 4, protective jacket.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is conducted further description.

Embodiment mono-

The present embodiment provides a kind of chest expander, please refer to Fig. 1, this chest expander comprises: gripping handle 1, some springs 2 and the built-in rope 3 of spring, the two ends of each root spring 2 are removably connected with gripping handle 1 respectively, the inside of each root spring 2 is provided with a built-in rope 3 of spring, the two ends of the built-in rope 3 of spring are individually fixed in corresponding spring 2 ends, the length of the built-in rope 3 of spring and spring 2 maximum tension states equal in length.Like this, spring 2 is detachable, is applicable to the people of different strength and needs, and the built-in rope 3 of spring is set in the inside of spring 2, and, when spring is broken, the broken end fractureing can not scraped and is suspended to above personal and damages.

The outer cover of spring 2 is provided with the protective jacket 4 of one deck flexibility, protective jacket 4 is at the telescopic elastic component of length direction, the two ends of protective jacket 4 are connected with gripping handle 1 by drag-line respectively, and protective jacket 4 is consistent in the maximum tension length of length direction and the maximum tension length of described spring 2.Because people are to stretch near chest, neck or neck conventionally when using chest expander to take exercises, in the process of shrinking again after spring 2 is stretched, easily clamp skin or hair, this chest expander arranges protective jacket 4 and can avoid the accident of clamping skin or hair to occur.

Protective jacket 4 entangles all springs 2 of chest expander simultaneously, and protective jacket 4 is transparent elastic cover, can be specifically transparent elastic rubber sleeve or flexible fiber cover or mull cover.

Embodiment bis-

The present embodiment provides a kind of chest expander, please refer to Fig. 2, this chest expander comprises: gripping handle 1, some springs 2 and the built-in rope 3 of spring, the two ends of each root spring 2 are removably connected with gripping handle 1 respectively, the inside of each root spring 2 is provided with a built-in rope 3 of spring, the two ends of the built-in rope 3 of spring are individually fixed in corresponding spring 2 ends, the length of the built-in rope 3 of spring and spring 2 maximum tension states equal in length.Like this, spring 2 is detachable, is applicable to the people of different strength and needs, and the built-in rope 3 of spring is set in the inside of spring 2, and, when spring is broken, the broken end fractureing can not scraped and is suspended to above personal and damages.

The outer cover of spring 2 is provided with the protective jacket 4 of one deck flexibility, protective jacket 4 is at the telescopic elastic component of length direction, the two ends of protective jacket 4 are connected with the corresponding end of spring 2 by drag-line respectively, and protective jacket 4 is consistent in the maximum tension length of length direction and the maximum tension length of described spring 2.Because people are to stretch near chest, neck or neck conventionally when using chest expander to take exercises, in the process of shrinking again after spring 2 is stretched, easily clamp skin or hair, this chest expander arranges protective jacket 4 and can avoid the accident of clamping skin or hair to occur.
