Description
Technical field
The present invention relates to a kind of chest expander for being easy to protect, belong to technical field of sports apparatus.
Background technology
Chest expander, is a kind of apparatus for being suitable for national physical training exercise.Taken exercise and be advantageous in that using chest expander：The upper arm two
Flesh, which is one piece, the muscle of two flesh heads, and its main function is to crook one's arm.When crooking one's arm, other one piece of muscle has equally also been used --
Brachialis.And only when doing the motion lifted on some forearms, such as high-order curved act of chest expander or trans high-order chest expander toy, brachialis
Just can fully it be taken exercise.In addition, the major muscles brachioradialis on forearm top, also play many effects in bent arm action, and
Being lifted by chest expander lateral bending can make brachioradialis be strengthened.
Existing chest expander can not realize protection when in use, cause skin to be clipped in spring, while pull handle is without anti-
Shield, its security is low, complex operation.
The content of the invention
In view of the above-mentioned problems, the technical problem to be solved in the present invention is to provide a kind of chest expander for being easy to protect.
A kind of chest expander for being easy to protect of the present invention, it includes pull handle, connecting seat, tension spring, protective jacket, screw thread
Set, screw rod, connection pivoted housing, connecting spring, protective air-bag；It is connected with the inside of the pull handle inside connecting seat, the connecting seat
Lateral wall be provided with several thread bush, the thread bush and be connected with screw rod, be connected with connection pivoted housing on the outside of the screw rod,
Connecting spring is connected between described two connection pivoted housings, the outer surface of the connecting spring is provided with protective air-bag, the drawing
It is provided with the madial wall of handle on arc ring, the madial wall of the connecting seat and is connected with connecting spring, before the connecting spring
End is provided with protective air-bag.
Preferably, the outer surface of the connecting spring is socketed with dirt-proof boot.
Preferably, being provided with inflation and deflating valve on the protective air-bag.
Preferably, the connection pivoted housing includes connecting shaft and pivoted housing, the outside connection pivoted housing of the connecting shaft.
Preferably, the protective jacket is flexible type protective jacket.
Compared with prior art, beneficial effects of the present invention are：Quick regulation and protection are easy to implement, safety is improved
Property, easy to use, easy to operate, efficiency high.
Brief description of the drawings：
For ease of explanation, the present invention is described in detail by following specific implementations and accompanying drawing.
Fig. 1 is structural representation of the invention.
In figure：1- pull handles；2- connecting seats；3- tension springs；4- protective jackets；5- thread bush；6- screw rods；7- connection pivoted housings；
8- connecting springs；9- protective air-bags.
Embodiment：
To make the object, technical solutions and advantages of the present invention of greater clarity, below by the specific implementation shown in accompanying drawing
Example describes the present invention.However, it should be understood that these descriptions are merely illustrative, and it is not intended to limit the scope of the present invention.This
Outside, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring idea of the invention.
As shown in figure 1, present embodiment uses following technical scheme：It includes pull handle 1, connecting seat 2, tension spring
3rd, protective jacket 4, thread bush 5, screw rod 6, connection pivoted housing 7, connecting spring 8, protective air-bag 9；The inner side of the pull handle 1 is connected with
Lateral wall inside joint chair 2, the connecting seat 2 is provided with several thread bush 5, the thread bush 5 and is connected with screw rod 6, described
The outside of screw rod 6 is connected between connection pivoted housing 7, described two connection pivoted housings 7 and is connected with connecting spring 8, the connecting spring 8
Outer surface be provided with protective air-bag 9, the madial wall of the pull handle 1 and be provided with arc ring, on the madial wall of the connecting seat 2
Connecting spring 8 is connected with, the front end of the connecting spring 8 is provided with protective air-bag 9.
