In this embodiment, T shape base 1, L shape support 2 and sleeve pipe 3 all adopt the iron material to make, and this material has good wear-resisting corrosion resistance, and the structure is firm, and advantages such as cost is lower prolong its life.

Further, the first rotating shaft 21 penetrates through the through hole 121, the L-shaped support 2 is rotatably connected with the vertical rod 12 through the first rotating shaft 21, and a certain gap exists between the first rotating shaft 21 and the inner wall of the through hole 121, so that the vertical end of the L-shaped support 2 can rotate around the first rotating shaft 21.

Besides, the fixing block 321 is adapted to the inner diameter of the sleeve 3, and the fixing block 321 is in sleeve fit with the sleeve 3, in this embodiment, the inner diameter of the sleeve 3 is preferably 10cm, so that the fixing block 321 can be used to compress the spring 31 in the sleeve 3.

It should be noted that the second rotating shaft 331 penetrates through the connecting joint 323, the pressing rod 32 is rotatably connected with the rotating base 33 through the second rotating shaft 331, a through hole matched with the diameter of the second rotating shaft 331 is formed in the connecting joint 323, and a certain gap exists between the second rotating shaft 331 and the through hole, so that the top end of the pressing rod 32 can rotate around the second rotating shaft 331, and the pressing rod 32 can be kept in a vertical state all the time when a user lifts the L-shaped bracket 2 up and down.

Specifically, the top end of the pressure lever 32 is tightly welded with the connector 323, and the bottom end of the pressure lever 32 is tightly welded with the fixing block 321, so that the stability of the device is improved.

Furthermore, the user selects the spring 31 with a proper stiffness coefficient to train the dorsal muscles according to the training intensity, and puts the spring 31 into the sleeve 3 to train, wherein the spring 31 with a larger stiffness coefficient is more difficult to be extruded and deformed, and the training intensity is higher, and conversely, the spring 31 with a smaller stiffness coefficient is less easy to be extruded and deformed, and the training intensity is lower.

In this embodiment, a user sits on the cushion 111 of the support 11 with the back facing the L-shaped support 2, holds the handle 221 with both hands, and lifts the L-shaped support 2 up and down, because the vertical end of the L-shaped support 2 is rotatably connected to the vertical rod 12 of the T-shaped base 1 through the first rotating shaft 21, the L-shaped support 2 drives the press rod 32 on the rotating base 33 to press downward in the process of rotating around the first rotating shaft 21, because the top end of the press rod 32 is rotatably connected to the press rod 32 through the second rotating shaft 331, the user can always keep the press rod 32 in a vertical state when lifting the L-shaped support 2 up and down, and the fixing block 321 arranged at the bottom end of the press rod 32 extends into the sleeve 3 and compresses the spring 31 in the sleeve 3, thereby completing the training of the dorsal muscles, and simultaneously, the user selects the spring 31 with a proper stiffness coefficient according to the training intensity, and put spring 31 into sleeve pipe 3 and carry out the training of back muscle, the great spring 31 of coefficient of stiffness, because difficult by extrusion deformation, training intensity is higher, on the contrary, the less spring 31 of coefficient of stiffness, because easily by extrusion deformation, training intensity is lighter, simple structure, convenient to use solves the training intensity of back muscle training ware be not convenient for adjust the training ware, the problem that the function is comparatively single.

Example 2

As the utility model discloses a second kind of preferred embodiment is equipped with the leather sheath 222 on the handle 221, and leather sheath 222 cup joints the cooperation with handle 221, and leather sheath 222 adopts the rubber material in this embodiment, and this material has good wear-resisting corrosion resistance, and advantages such as antiskid effect is better can only increase the frictional force between user's palm and handle 221, prevents that the palm from skidding when the training.

Example 3

As the utility model discloses a third kind preferred embodiment, the bottom surface of fixed block 321 has closely welded spacing post 322, and spacing post 322 stretches into spring 31's inner circle, is convenient for utilize spacing post 322 to play limiting displacement to spring 31, prevents that spring 31 from taking place to rock when the training.

The utility model discloses a multi-functional back muscle training ware is when using, the user sits on cushion 111 on pillar 11 back to L shape support 2, both hands hold handle 221, and carry out the operation of carrying up and down to L shape support 2, because the vertical end of L shape support 2 rotates through first pivot 21 and montant 12 on the T shape base 1 and is connected, therefore, L shape support 2 drives depression bar 32 on the seat 33 and extrudes downwards in the process of rotating around first pivot 21, because the top of depression bar 32 is connected with depression bar 32 through second pivot 331 and rotation, when carrying up and down L shape support 2, depression bar 32 can remain vertical state all the time, and make the fixed block 321 that the depression bar 32 bottom set up stretch into sleeve pipe 3, and compress the spring 31 in sleeve pipe 3, the reciprocal operation process, with this, accomplish the training to the back muscle, and simultaneously, the user is according to intensity, select the spring 31 of suitable stiffness coefficient, and put into spring 31 and carry out the training of back muscle in the sleeve pipe 3, the great spring 31 of stiffness coefficient, because difficult by extrusion deformation, training intensity is higher, on the contrary, the less spring 31 of stiffness coefficient, because easy by extrusion deformation, training intensity is lighter, in addition, the bottom surface of fixed block 321 is equipped with spacing post 322, spacing post 322 stretches into spring 31's inner circle, be convenient for utilize spacing post 322 to play limiting displacement to spring 31, prevent that spring 31 from taking place to rock when training, moreover, the steam generator is simple in structure, high durability and convenient use, solve the training intensity that back muscle training ware is not convenient for adjust the training ware, the comparatively single problem of function, be convenient for popularize and promote.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
