The falling-off preventing treadmill has the advantages that the pedals can be effectively prevented from falling off, and the falling-off preventing treadmill is easy to assemble.

Description

Anti-rash dress treadmills

Technical field

The present invention relates to body-building apparatus technical field, especially relate to a kind of anti-rash dress treadmills.

Background technology

Treadmills is the current comparatively body-building apparatus of fashion.Conventionally, this treadmills comprises underframe, and this underframe is provided with 2 pedals, and these 2 pedal bottoms are connected with elastic force apparatus.This elastic force apparatus can be the parts such as stage clip, hydraulic cylinder.Its defect is: because pedal is many, by screw, be limited on underframe, thereby screw used is easy to come off and cause pedal to come off, user needs frequent inspection and maintenance then, very inconvenience.

Summary of the invention

The object of this invention is to provide a kind of anti-rash dress treadmills, it has the advantages that effectively to prevent that pedal from coming off and being easy to assemble.

The technical solution adopted in the present invention is: anti-rash dress treadmills, comprise underframe, this underframe is provided with 2 pedals, these 2 pedal bottoms are connected with elastic force apparatus, the left and right sides on described underframe top is all welded with an inner tube that is level, this inner tube outer end has at least 2 locating slots, and the inside of this inner tube is provided with the female installing plate of a middle part tool, the first locating piece that the edge of this installing plate has and this locating slot matches between two, after the outer end bundle mouth of this inner tube, this installing plate is stuck in to the outer end oral area of this inner tube, simultaneously, the cover that the outer gap of this inner tube coordinates has outer tube, these 2 pedals are welded in respectively on the outer surface of these 2 outer tubes, and, in this internal thread, be bolted with screw, on this screw, cover has pad, the second locating piece that the inner surface of this pad is provided with and this locating slot matches between two.

The outside that is positioned at this pad on described screw is also overlapped and is had sheathing.

The advantage that the present invention has is: can effectively prevent that pedal from coming off and being easy to assembling.The pad contacting with outer tube on anti-rash dress treadmills of the present invention cannot rotate, and can not contact with outer tube, thereby screw can not become flexible for the screw of spacing shim, and pad can not come off then, has avoided being welded with the coming off of outer tube of pedal.Meanwhile, such treadmills is without carrying out the too much operations such as location and installation, then comparatively simple.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described:

Fig. 1 is the anti-rash dress treadmills schematic perspective view of embodiments of the invention;

Fig. 2 is the perspective exploded view of embodiments of the invention middle external tube, inner tube and attaching parts thereof.

The specific embodiment

Embodiment, is shown in shown in Fig. 1 and Fig. 2: anti-rash dress treadmills, comprises underframe 10.This underframe 10 is provided with 2 pedals 20, and these 2 pedal 20 bottoms are connected with elastic force apparatus (not shown on figure).More specifically, the left and right sides on these underframe 10 tops is all welded with an inner tube 30 that is level.These inner tube 30 outer ends have at least 2 locating slots 31.So-called outer end, refers to the one end away from the center of this underframe 10.The inside of this inner tube 30 is provided with the installing plate 40 that a middle part has internal thread 41, the first locating piece 42 that the edge of this installing plate 40 has and this locating slot 31 matches between two.That is, this first locating piece 42 corresponding being stuck in this locating slot 31 between two.After the outer end bundle mouth of this inner tube 30, this installing plate 40 is stuck in to the outer end oral area of this inner tube 30.That is, by modes such as extruding, make the outer end oral area of this inner tube 30 form bundle mouthful.Meanwhile, the cover that the outer gap of this inner tube 30 coordinates has outer tube 50, and these 2 pedals 20 are welded in respectively on the outer surface of these 2 outer tubes 50.And, in this internal thread 41, be bolted with screw 60.The second locating piece 71 that on this screw 60, cover has pad 70, the inner surface of this pad 70 to be provided with and this locating slot 31 matches between two.So-called inner surface refers to this pad 70 near a side surface of the center of this underframe 10.That is, after this screw 60 is screwed, 70 pairs of these outer tubes 50 of this pad have carried out spacing this outer tube 50 that makes and cannot skid off from this inner tube 30, and this second locating piece 71 corresponding snapping in this locating slot 31 between two, and this pad 70 can not produce rotation then.And, be easy to loosening screw 60 and can not contact with this outer tube 50, avoided the loosening of this screw 60.

Further say, the outside that is positioned at this pad 70 on this screw 60 is also overlapped and is had sheathing 80.Like this, increased the aesthetic measure of this treadmills, and when adopting elastomeric material to prepare this sheathing 80, this sheathing 80 also plays the fastening effect with buffering to a certain degree that makes this screw 60.

The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
