Abstract
The utility model discloses a kind of back strength tester, it includes an instrument box, it is installed on a cylinder, this cylinder is fixed on a base, it is fixed by a screw between cylinder and base, it is provided with a power transmission case in base, this power transmission case is relative with cylinder to be respectively arranged on base, power transmission case is arranged over a grip part, it is attached by a chain between this grip part and power transmission case, when grip part drives chain movement, grip part has an active force to chain, this active force is conveyed to power transmission case, by this power transmission case, power is reacted to instrument box, so, power scattering and disappearing in the middle of transmission can be greatly reduced, energy accurate response goes out the exercise intensity of user, the exercise time of Reasonable adjustment user.
Description
[technical field]
This utility model relates to a kind of back strength tester, the back strength tester of a kind of open air.
[background technology]
People's Working Life rhythm is fast now, make health tired out, people can often perform physical exercise by some body-building apparatus, such as back strength tester is exactly one of which, its structure is the simplest, one instrument box directly arrange in pairs or groups one grip part use, when user is when applying strength to grip part, instrument box then has certain reaction, but due to this simple in construction, power can be scattered and disappeared a lot during transmission, therefore cannot learn that the exercise intensity of user is the most reasonable, lack the effect then not having exercise, many then health can be harmful to, make health more tired out, even strain.
Therefore, it is necessary to design a kind of good back strength tester, to overcome the problems referred to above.
[utility model content]
For background technology problem encountered, the purpose of this utility model is to provide a kind of back strength tester coordinating to come accurate test number utilizing power transmission case and chain.
For achieving the above object, this utility model employing techniques below means:
A kind of back strength tester, it includes an instrument box, it is installed on a cylinder, this cylinder is fixed on a base, it is fixed by a screw between cylinder and base, it is provided with a power transmission case in base, this power transmission case is relative with cylinder to be respectively arranged on base, power transmission case is arranged over a grip part, being attached by a chain between this grip part and power transmission case, when grip part drives chain movement, grip part has an active force to chain, this active force is conveyed to power transmission case, reacts power to instrument box by this power transmission case.
Further, being provided with a hook part between power transmission case and base, this hook part is to power transmission case and base rotation.
Further, portion of chain can flexibly shrink in power transmission case.
Compared with prior art, this utility model has the advantages that
Above-mentioned back strength tester is when user uses, user can grasp grip part, being attached by chain between grip part and power transmission case, when grip part drives chain movement, grip part has an active force to chain, this active force is conveyed to power transmission case, by this power transmission case, power is reacted to instrument box, so, power scattering and disappearing in the middle of transmission can be greatly reduced, energy accurate response goes out the exercise intensity of user, the exercise time of Reasonable adjustment user.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram of this utility model back strength tester.
The drawing reference numeral explanation of detailed description of the invention:
| Instrument box 1 | Cylinder 2 | Screw 3 |
| Base 4 | Power transmission case 5 | Hook part 6 |
| Grip part 7 | Chain 8 |
[detailed description of the invention]
For ease of being better understood from the purpose of this utility model, structure, feature and effect etc., in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Refer to Fig. 1, this utility model back strength tester, temper use out of doors with for user (not shown).
Refer to Fig. 1, back strength tester includes an instrument box 1, it is installed on a cylinder 2, this cylinder 2 is fixed on a base 4, it is fixed by a screw 3 between cylinder 2 and base 4, it is provided with a power transmission case 5 in base 4, this power transmission case 5 is relative with cylinder 2 to be respectively arranged on base 4, and between power transmission case 5 and base 4, it is provided with a hook part 6, power transmission case 5 is rotated by this hook part 6 with base 4, facilitating user different angles to use this back strength tester, health need not one angle of holding and the action ossify, and possesses bigger motility.
Refer to Fig. 1, power transmission case 5 is arranged over a grip part 7, it is attached by a chain 8 between this grip part 7 and power transmission case 5, when grip part 7 drives chain 8 to move, grip part 7 has an active force to chain 8, this active force is conveyed to power transmission case 5, by this power transmission case 5, power is reacted to instrument box 1, and chain 8 part can flexibly shrink in power transmission case 5, so when child (not shown) in use, need not the chain 8 so grown, it would not loose, child is facilitated to use, when adult (not shown) in use, can be elastic chain 8 is pulled out suitable length, adult is facilitated to use.
Refer to Fig. 1, above-mentioned back strength tester is when user uses, and user can grasp grip part 7, is attached by chain 8 between grip part 7 and power transmission case 5, when grip part 7 drives chain 8 to move, grip part 7 has an active force to chain 8, and this active force is conveyed to power transmission case 5, reacts power to instrument box 1 by this power transmission case 5, so, can greatly reduce power scattering and disappearing in the middle of transmission, energy accurate response goes out the exercise intensity of user, the exercise time of Reasonable adjustment user.
Detailed description above is only the explanation of the preferred embodiment of this utility model, non-therefore limits to the scope of the claims of the present utility model, so, the equivalence techniques change that all utilization this creation description and diagramatic content are done, it is both contained in the scope of the claims of the present utility model.
