Description
Technical field
This utility model relates to sports equipment technical field.
Background technology
Along with expanding economy and the busy work of people so that people increasingly lack suitable outdoor activity.Along with the raising of people's living standard, tempered the part becoming many people life by body-building apparatus, especially small-sized body-building apparatus is more paid close attention to, and existing applicable home-use equipment is fewer.Such as, chest-developer is subject to liking of many youth, middle age and student.But existing chest-developer is made up of two handles and middle spring, and the maximum drawback of this chest-developer is: one, resistance is unadjustable, and chest-developer can not be adjusted by body builder according to self-demand.Thus decreasing demand crowd, it is impossible to provide more appropriate body-building strength to body builder.Two, the life-span is short, because the principle of existing chest-developer is to reach to provide Hui Li and resistance by flexural spring, and spring is by bending the best usage that generation power is not spring.Fact proved, existing chest-developer General Life is comparatively short, and camber of spring or spring generally can be occurred after using 3000-8000 time to disconnect.
Utility model content
Technical problem to be solved in the utility model, is the technical deficiency for above-mentioned existence, it is provided that a kind of strength scalable chest-developer, and its simple in construction is easy to use, it is possible to regulate the size of the strength of chest-developer according to the demand of user.
The technical solution adopted in the utility model is: provide a kind of strength scalable chest-developer, including two armed levers and U-shaped gripper shoe；The end of each armed lever is fixedly connected with gear, and two gear engagements rotating shaft are connected to U-shaped gripper shoe；Each armed lever other end is provided with handle；Each handle outer end is mounted on protection hand strap；U-shaped support plate top surface is fixed with support bar；Post upper is fixed with pulling force crossbeam；Pulling force crossbeam two ends all slidably connect slide block；The upper end of each slide block is by puller bolt and the fastening of pulling force crossbeam；The lower end of each slide block is being connected to tension spring；The lower end of tension spring is connected with the armed lever of homonymy；Pulling force beam surface upper is longitudinally provided with pulling force scale.
Optimizing the technical program further, the support bar of strength scalable chest-developer is telescopic supporting rod, and is held out against fixing by puller bolt.
Optimizing the technical program further, armed lever and the pulling force crossbeam of strength scalable chest-developer are glass fibre material.
The beneficial effects of the utility model are: 1, user two holds handle, and two handss firmly break downwards armed lever simultaneously, and two armed levers, under the rotation of gear, move downward；And U-shaped gripper shoe position will not become, the upper end that pulling force crossbeam hauls tension spring is motionless, and when armed lever moves downward, tension spring is elongated, and has a reverse tightening force can act on armed lever, thus can complete the train on of chest-developer；When user needs strength to alleviate, it is possible to slide block is slided to the inside, and the displacement slided in both sides wants consistent, and such both sides strength just can be identical；The advantage of this device is in that: product structure is simple, and cost is low, it is possible to better meet the user demand to strength, it is to avoid user buys the chest-developer of multiple different strength.2, described support bar is telescopic supporting rod, and holds out against fixing by holding out against screw, if user needs strength bigger；Can skid to outermost, telescopic supporting rod is reached highest point simultaneously, increasing the distance between pulling force crossbeam and armed lever, pulling force crossbeam pulls up tension spring, and user is when taking exercise, it is longer that tension spring is drawn, the reverse contractility of such tension spring can be bigger, it is possible to meets the demand that user is big to strength, and slide block is moved to inner side, telescopic supporting rod is preferably minimized, and is the minimum state of this device strength；So can better meet user's demand to different strength.3, armed lever and pulling force crossbeam are glass fibre material, according to glass fibre characteristic, under not reducing the effect that user uses, it is possible to alleviate the weight of this device, be user-friendly to.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in Figure 1-2, strength scalable chest-developer, including two armed levers 1 and U-shaped gripper shoe 2；The end of each armed lever 1 is fixedly connected with gear 3, and two gear 3 engagements rotating shaft are connected to U-shaped gripper shoe 2；Each armed lever 1 other end is provided with handle 4；Each handle 4 outer end is mounted on protection hand strap 5；U-shaped gripper shoe 2 end face is fixed with support bar 6；Support bar 6 upper end is fixed with pulling force crossbeam 7；Pulling force crossbeam 7 two ends all slidably connect slide block 8；The upper end of each slide block 8 is fastened by puller bolt and pulling force crossbeam 7；The lower end of each slide block 8 is being connected to tension spring 9；The lower end of tension spring 9 is connected with the armed lever 1 of homonymy；Pulling force crossbeam 7 upper surface is longitudinally provided with pulling force scale.Described support bar 6 is telescopic supporting rod, and holds out against fixing by holding out against screw.Armed lever 1 and pulling force crossbeam 7 are glass fibre material.
User two holds handle 4, and two handss firmly break downwards armed lever 1 simultaneously, and two armed levers 1, under the rotation of gear 3, move downward；And U-shaped gripper shoe 2 position will not become, the upper end that pulling force crossbeam 7 hauls tension spring 9 is motionless, and when armed lever 1 moves downward, tension spring 9 is elongated, and has a reverse tightening force can act on armed lever 1, thus can complete the train on of chest-developer；When user needs strength to alleviate, it is possible to slide block 8 is slided to the inside, and the displacement that two slider edges 8 slide wants consistent simultaneously, and such both sides strength just can be identical；The advantage of this device is in that: product structure is simple, and cost is low, it is possible to better meet the user demand to strength, it is to avoid user buys the chest-developer of multiple different strength.Described support bar 6 is telescopic supporting rod, and holds out against fixing by holding out against screw, if user needs strength bigger；Slide block 8 can be slided into outermost, telescopic supporting rod is reached highest point simultaneously, increase the distance between pulling force crossbeam 7 and armed lever 1, pulling force crossbeam 7 pulls up tension spring 9, user is when taking exercise, it is longer that tension spring 9 is drawn, and the reverse contractility of such tension spring 9 can be bigger, it is possible to meets the demand that user is big to strength；Slide block 8 is moved to inner side, and telescopic supporting rod is preferably minimized, and is the minimum state of this device strength；So can better meet user's demand to different strength.Armed lever 1 and pulling force crossbeam 7 are glass fibre material, according to glass fibre characteristic, under not reducing the effect that user uses, it is possible to alleviate the weight of this device, be user-friendly to.
Points for attention during use: in use, user must pack in protecting hand band 5 by handle, in order to avoid hands is sliding makes cost apparatus bullet wound user；Armed lever 1 is blocked by U-shaped gripper shoe 2 end face, moves upward so will not be pulled by tension spring 9, and armed lever 1 can only be moved downwards by user.
Glass fibre is the Inorganic Non-metallic Materials of a kind of excellent performance, and advantage is good insulating, thermostability is strong, corrosion resistance good, and mechanical strength is high；This device adopts glass fibre material, when good mechanical performance, moreover it is possible to alleviate the weight of this device, be user-friendly to.
This device should be held out against fixing between slide block 8 and pulling force crossbeam 7 by puller bolt；Prevent in a situation of use where, occur that slide block 8 slides, cause user cannot better use this device.
