Because the running table part is light, the folding running table saves labor. After being folded, the angle between the running platform and the ground is about 90 degrees, and the occupied space is small. The front roller shaft and the running board are not directly connected, the front roller shaft and the running board are required to be respectively adjusted in the assembly process, the axis of the front roller shaft is parallel to the transverse symmetrical center line of the running board, the assembly precision is not easy to control, and the assembly cost is high.

The left fixed seat 3 of the running platform and the right fixed seat 4 of the running platform are all in the shape of angle steel which is vertically placed, the angle steel comprises a rear vertical plate 20 and a front vertical plate 18, the included angle between the rear vertical plate 20 and the front vertical plate 18 is 90 degrees, a U-shaped groove for bearing a front roller shaft 44 is arranged on the rear vertical plate 20, and a fixing nut 21 is fixedly arranged on the front vertical plate 18 and the rear vertical plate 20. Standing on one side of the running table
The left end of the front roller shaft 44 is provided with a through hole, and a screw is screwed into the fixing nut 21 of the left fixed seat 3 of the running platform through the through hole to fixedly connect the front roller shaft 44 with the machine base 1. A through hole is provided at the right end of the front drum shaft 44, and a screw is screwed into the fixing nut 21 through the through hole to fixedly connect the front drum shaft 44 with the housing 1.
The coaxial design of the running platform 30 and the specific structure of the independent running platform 30 are as follows: the running block 30 is shown in fig. 10: the running block 30 has a rectangular frame structure composed of a left bracket 31, a right bracket 32, a front roller 33 and a rear roller 34.
A front drum shaft left mounting hole is provided at the front end of the left bracket 31, a front drum shaft right mounting hole is provided at the front end of the right bracket 32, and a center line of the front drum shaft left mounting hole and the front drum shaft right mounting hole coincides with a center axis of the front drum 33. The front drum shaft 44 of the front drum 33 is disposed in the front drum shaft left mounting hole and the front drum shaft right mounting hole in a clearance fit so that the left and right brackets (31, 32) can pivot about the front drum shaft 44 at the same time.
The running board 35 is fixed on the left and right brackets (31, 32); a running belt 36 surrounding the front and rear rollers (33, 34) and the running plate 35; the front roller 33 has a function of carrying the running and is also a front end cross member of the frame.
The front drum 33 is provided with a pulley 19, and the motor 11 drives the front drum 33 to rotate via a v-belt 39 fitted over the pulley 19 of the front drum 33.
The technique of coaxial design allows the treadmill 30 to be assembled into a complete stand alone treadmill and the tread band tension can be adjusted on the complete treadmill (by adjusting the left and right adjustment screws 37, 38 to tighten the tread band 36 to the desired tension).
As shown in fig. 10, the left and right mounting holes of the front roller on the left and right brackets (31, 32) are mounted on the front roller shaft 44, and the coaxial design requires lengthening the front roller shaft (5-12 mm for each of the left and right ends of the front roller shaft), leaving the mounting dimensions of the left and right mounting holes of the front roller. In the process of using the running machine, in order to meet the requirement that the front roller shaft does not flex when bearing, the diameter and the length of the front roller shaft are designed according to the width dimension range of the running machine (the relation between the width dimension of the running machine which is generally designed and the maximum load born by the running machine is that the maximum load born by the running machine is small when the width of the running machine is narrow). If the material is selected as the most common steel Q235, the size range of the front roller shaft of the common running machine designed by taking the above factors into consideration is as follows: the length is 500-800 mm, and the diameter phi is 12-22 mm. The length of the shaft is short, the shaft selecting diameter is small, and conversely, the shaft selecting diameter is large. The size range of the front roller shaft of the running machine with the coaxial design is as follows: the length is 510-824 mm, and the diameter phi 12-22 mm. The comparison result of the two is: the total length range of the shaft is prolonged by 10-24 mm, the diameter range of the shaft is the same, and the fixed screw of M10-M14 mm for the fixed running platform is enough for use, while the diameter size range of the fixed screw of the fixed running platform is contained in the diameter size range of the shaft of the front roller, so that the force applied by the running platform is satisfied, and the shaft diameter does not need to be thickened.
When the axial diameter of the front drum shaft is phi 12 mm and the axial length is 510-570 mm, the front drum shaft does not flex and deform under rated load; the axial diameter of the front drum shaft is phi 15 mm, and when the axial length is 510-650 mm, the front drum shaft does not flex and deform under rated load; the axial diameter of the front drum shaft is more than or equal to phi 17-phi 22 mm, and when the axial length is 510-850 mm, the front drum shaft does not generate deflection deformation under rated load.
In the coaxial design, the left and right mounting holes of the front roller on the left and right brackets (31, 32) are mounted on the front roller shaft 44 at positions which are closer to the left fixed seat 3 and the right fixed seat 4 of the running platform 1, and the shearing force of the front roller shaft on the connecting point is small (because the closer to the moment arm is shorter), as shown in fig. 6, 7, 8 and 9. As shown in fig. 7, the range of mounting positions of the right bracket 32: the allowable distance between the right side of the front end ribbon-shaped flat plate 43 and the left side of the rear vertical plate 20 is in the range of 0.5 to 10 mm. The left bracket 31 is mounted in the same position as the right bracket 32.
We have developed two types of treadmills with the following dimensions:
The first: the front drum shaft length 624 mm, the shaft diameter phi 15 mm, the mounting position of the right bracket 32 is: as shown in fig. 7, the right side of the front end ribbon-shaped flat plate 43 is 2mm away from the left side of the rear riser 20. The mounting position of the left bracket 31 is the same as that of the right bracket 32;
The second: the front roller shaft length is 564 mm, the shaft diameter is 12 mm, and the mounting position of the right bracket 32 is: as shown in fig. 7, the right surface of the front end ribbon-shaped flat plate 43 is 2mm away from the left surface of the rear riser 20, and the left bracket 31 is mounted at the same position as the right bracket 32.
As shown in fig. 11, a force arm 2, a left fixed seat 3 and a right fixed seat 4 of the running platform for bearing the running platform 30, a motor fixed seat 5, a locking hole 45 and a power supply fixed seat 6 are fixedly arranged on the machine base 1. (two pin holes for fixing the motor are designed on the motor fixing seat 5), and a power panel is fixed on the power supply fixing seat 6. The base 1 is fixedly provided with a bottom leg fixing seat, and the bottom leg fixing seat comprises a left bottom leg fixing seat 9 and a right bottom leg fixing seat 10. The left bottom leg fixing seat 9 is provided with a left bottom leg 16, and the right bottom leg fixing seat 10 is provided with a right bottom leg 17 (as shown in fig. 12). The arm 2 is provided with an armrest fixing seat 8, an instrument fixing member 7 is arranged between the two armrest fixing seats 8, and an instrument 12 (shown in fig. 12) is fixedly arranged on the instrument fixing member 7. The armrest fixing seat 8 is provided with an armrest 13 (as shown in fig. 12).
As shown in fig. 12, the motor 11, the meter 12, the armrest 13, the power board 14, and the deck locking device 15 have been mounted one by one on the base 1.
The base 1 and the running block 30 are assembled, and fig. 6 is a schematic view of the unfolded running block, and fig. 8 is a schematic view of the folded running block. The assembly steps are as follows:
(1) The front roller 33 of the running table 30 is fixedly connected with the left running table fixing seat 3 and the right running table fixing seat 4 of the machine base 1. The method comprises the following steps: the left and right fixing screws 40 (the right fixing screws 40 are shown in fig. 9) are respectively fixed on the fixing nuts 21 of the left fixing seat 3 and the right fixing seat 4 of the running table.
(2) The front drum 33 and the motor 11 are connected by a v-ribbed belt 39. Then, the v-ribbed belt 39 is pulled to a desired tension by adjusting the position of the motor 11. The running machine is assembled through the two steps, and has the advantages that: the two independent components (the base 1 and the running platform 30) are connected and assembled together, so that the operation is very simple, time-saving and labor-saving, the assembly precision is high, the labor efficiency is high, and the production cost is low. Conventional treadmills are difficult to implement.
As shown in fig. 8 and 9: the running table locking device 15 is arranged at the right lower part of the running machine base 1, the front part of the right bracket 32 is a strip-shaped flat plate 43, and the strip-shaped flat plate 43 is matched with the running table locking device 15 to realize the locking and positioning of the running table. Fig. 4 is a schematic view of the frame when seen from the side of the running board to the frame 1.
As shown in fig. 12, 14 and 15, the running platform locking device 15 includes a locking block fixing member 23 and a blocking piece 22 fixedly arranged on a rear vertical plate 20 of a right fixing seat 4 of the running platform, wherein the locking block fixing member 23 is an inverted U-shaped groove body, and is composed of two vertical surfaces and a top surface which are arranged at intervals, pin holes are arranged at the lower parts of the two vertical surfaces, a locking block 24 is hinged between the two vertical surfaces in the locking block fixing member 23 through a pin shaft, and a notch is formed at the upper part of the rear vertical plate 20 corresponding to the upper part of the locking block fixing member 23 for the upper part of the locking block 24 to extend out of the rear vertical plate 20.
Fig. 14 is a part view of the right treadmill mount 4, the rear riser 20 of the right treadmill mount 4 being defined as a "blocking surface".
As shown in fig. 15, the locking block 24 comprises a 7-shaped structure formed by a transverse part and a vertical part, a vertical part nut is arranged at the lower end of the vertical part, and the vertical part nut is in threaded connection with the locking handle 25; the lower part of the vertical part is provided with a convex spring fixing seat, the nut and the spring fixing seat are distributed on two opposite surfaces of the vertical part, the spring fixing seat is provided with a spring, the other end of the spring is propped against the baffle 22, and the middle lower part of the vertical part is also provided with a pin hole above the spring fixing seat. As shown in fig. 9: the locking block 24 is installed in the U-shaped groove of the locking block fixing member 23 with a clearance fit therebetween, and is fixed together by a pin shaft 27. The locking block 24 is restrained in the locking block fixing piece 23, and can only rotate clockwise or anticlockwise by taking the pin shaft 27 as a rotating shaft; one end of the spring 26 is in contact with the baffle 22, and the other end is sleeved on the spring fixing seat of the locking block 24. When the vertical portion of the locking block 24 is in contact with the rear riser 20 (fig. 14) of the right fixed seat 4 of the running block, the locking block 24 cannot continue to rotate counterclockwise, but at this time the lateral portion of the locking block 24 has been protruded to the outside of the rear riser 20. The position of the lock block 24 is shown in fig. 9, where the lock block 24 is at the maximum angular position of counterclockwise rotation. Whether the lock block 24 is rotated clockwise or counterclockwise, the lock block 24 is constrained from continuing to rotate when rotated to the desired angle of design.
The bottom surface of the lateral portion of the lock block 24 is a slope, which is defined as an "automatic disengagement slope". The bottom surface of the transverse part of the locking block 24 is naturally intersected with the left side elevation of the middle section direction of the vertical part of the locking block 24. The left side elevation of the lock block 24 in the middle of the vertical portion is defined as a "constrained surface". And (3) injection: the 'automatic disengagement inclined plane' naturally intersects with the 'constrained surface'.
Action and function: fig. 9 shows the running block 30 in a folded state, in which the spring 26 always applies an elastic force to the lock block 24 to push the lock block 24, the lock block 24 is already at the maximum angular position after counterclockwise rotation, the lateral part of the lock block 24 extends below the band-shaped flat plate 43 in front of the right bracket 32 of the running block 30, and the running block 30 is locked.
To lower the running block 30, the running block 30 is first lightly pushed forward by hand so that the locking block 24 is not pressed by the running block 30, and simultaneously the locking handle 25 is pressed by the right foot, and the spring 26 is further compressed by the greater pressure to the left. The locking block 24 rotates clockwise by taking the pin shaft 27 as a rotating shaft, and rotates to the maximum angle required by design (at the moment, the spring is set to the maximum angle when compressed to the limit position), the transverse part of the locking block 24 is completely separated from the bottom surface of the strip-shaped flat plate 43 at the front end of the right bracket 32 of the running table 30, namely: the treadmill 30 is unlocked. The running block 30 is kept to be gradually placed on the ground (see fig. 6 and 7).
Note that: the locking handle 25 is not needed to be stepped on all the time in the operation process, and when the running platform 30 is unlocked and slowly falls down, the transverse part of the locking block 24 is contacted with the side surface of the strip-shaped flat plate 43 at the front end of the right bracket 32 of the running platform 30, so that the locking handle 25 is not needed to be forced.
If the running block 30 is folded again, the running block 30 is locked by simply lifting the running block 30 until it is folded to the position of fig. 8. The principle is as follows: when the running block 30 is lifted, the top surface of the front end ribbon-shaped flat plate 43 of the right bracket 32 of the running block 30 applies upward force against the inclined surface of the lateral part of the locking block 24. As shown in fig. 7, the "self-releasing slope" of the lock block 24 falls on the right bracket 32 of the running block 30, the lock block 24 starts to automatically rotate clockwise, when the running block 30 is folded under the front end band plate 43 of the right bracket 32 and passes the lateral part of the lock block 24, the lock block 24 starts to rotate counterclockwise under the urging force of the spring 26, and after turning to the maximum angle, the lateral part of the lock block 24 blocks the lower part of the front end band plate 43 of the right bracket 32, and the running block 30 is locked (fig. 9).
And (3) safety design: first layer security considerations: to lower the running block 30, the running block 30 is pushed forward and the locking handle 25 is depressed. Because the lock block 24 is subjected to a great pressure when the running block 30 is always pressed against the lock block 24, at this time, the lock block 24 is not easily rotated, and thus the running block 30 is not dropped by inadvertently touching the lock lever 25. No danger occurs.
Second layer security considerations: in order to prevent the danger of the running table 30 falling down by touching the two pieces (the locking handle 25 and the running table 30) by a child in the home in case of intention, the locking handle 25 can be detached (threaded connection, convenient disassembly and assembly) when the running machine is not used, and the locking handle 25 is like a key of a safety lock, so that the safety link is achieved.
The advantages are that: the locking device has the advantages of simple and smart structure, ingenious and reasonable design, easy processing and assembly, material and space saving, labor saving, safety and reliability and convenient use.

As shown in fig. 18, one end of the tightening strap 29 is fixed to the motor 11, and the other end is provided with a nut to be engaged with the tightening screw 41 provided in the locking hole when the v-ribbed belt 39 is to be tightened.
Step of installing motor 11 and advantages: the pin shaft of the motor connecting plate 28 on the motor 11 is connected with the pin hole of the motor fixing seat 5 on the machine base 1 (figure 11), the pin shaft is in clearance fit with the pin hole, and the motor 11 can rotate forwards or backwards (the direction far away from the running table 30 is the front direction or the reverse direction is the back direction) on the upper end surface of the motor fixing seat 5 by taking the pin shaft as a rotating shaft.
The poly V-belt 39 is hung on the front roller 33 and the belt wheel 19 of the motor 11, the tightening screw 41 (shown in fig. 16) passes through the locking hole of the stand 1 shown in fig. 11 from bottom to top (the locking hole is coincident with the position of the tightening screw 41 in fig. 16. At this time, the screw head of the tightening screw 41 is exposed at the bottom of the stand 1, the tightening screw 41 is the exposed screw head part of the same in fig. 16), then is connected with the nut of the tightening belt 29, the tightening screw 41 is screwed, the tightening belt 29 is pulled, the motor 11 is pulled to rotate forwards by taking the pin shaft as the rotating shaft, the poly V-belt 39 is pulled to be tightened until the required tension is reached, and the tightening screw is stopped.
As shown in fig. 16, the locking hole 45 is formed at the forefront end of the machine base 1, and the screw head of the tightening screw 41 is exposed at the lower end of the machine base 1, so as to facilitate the adjustment of the tension of the v-ribbed belt 39. Because the head of the tensioning screw 41 is always exposed, the tensioning screw is convenient for a user to adjust at any time according to needs when being used at ordinary times, and the case 42 is not required to be disassembled, so that the operation is simple and convenient. The adjustment of the after-sales door is not needed.
The motor connecting plate 28 and the tightening belt 29 on the motor 11 are very simple in structure and are made of few materials; the motor 11 is fixed on the motor fixing seat 5 simply and easily; tightening of v-ribbed belt 39 is also particularly easy. The outstanding advantages are: the operation is convenient, the structure is simple and reasonable, the material and production cost and after-sale cost are saved, and the use is convenient for users.
And (3) mounting-free design: foldable armrest: the state of the handrail 13 when the running machine is used is shown in fig. 1; when not in use, as shown in fig. 2. After-sales and users are free from the trouble of installing handrails; foldable bottom leg: the folding bottom leg needs to be unfolded when the treadmill is used or stored, as shown in fig. 1 and 2. At the moment, the running machine is stable in standing and cannot incline or roll over. When packing, the folding bottom legs are rotated and folded, as shown in fig. 3, so that the packing space is saved, the packing volume is small, and the packing device is easy to carry, saves labor and packing and transportation costs. After-sales and users are relieved of the trouble of installing the bottom leg.
